the invention and accompanying drawings will now be discussed in reference to the numerals provided therein so as to enable one skilled in the art to practice the present invention . the drawings and descriptions are exemplary of various aspects of the invention and are not intended to narrow the scope of the appended claims . turning now to fig1 , a top schematic view of a mobile of the present invention is shown . the term mobile is used because the device may be hung so as to be viewed by an infant in a bed . however , it will be appreciated that the device can be attached to various structures in a manner such that the mobile can be readily displayed to a child while not in bed . for example , the device can be attached to the side of a crib , on a frame adjacent a booster seat or even to the back of a seat in an automobile . the mobile 10 is primarily used to hold a book 14 in an open position so as to selectively display the pages 18 of the book to a child . the mobile 10 works best with books 14 that have thick cardboard pages 18 , such as conventional infant books as this allows the book to be held open even when the book is facing downward . specialized books 14 may be provided as is desired . for example , books 14 with plastic pages 18 may be provided for use in hospitals or the like as these books may be sterilized . clamps 22 , or other retention devices are used to hold the book 14 to the body 26 of the mobile 10 . it has been discovered that most of the thick paged infant books will stay open if a small inward pressure is applied to the front and back pages of the book in the directions indicated by arrows 30 . thus , the clamps 22 compress the book somewhat in the direction 30 and aid in keeping the book open . moving the two sides of the book 14 adjacent the spine 38 of the book in the directions shown by arrows 34 will turn the pages 18 of the book , while keeping the pages open so as to display the pages of the book to a child . a motor 42 , such as a stepper motor , with an output gear 46 may be selectively rotated to move gear members 50 , 54 in the directions shown by arrows 34 to turn the pages 18 of the book 14 . the motor 42 is typically controlled by signals from a computer controller 58 which is programmed to move the motor at the desired time to turn the pages , and to move the motor the desired amount to turn a single page at a time . the mobile 10 may include memory 62 which contains the operating firmware to operate the mobile , and may also contain a battery 66 to provide power . a power jack may also be provided . the book 14 is mounted to pivotable arms 70 or some other retaining device which pivot at pivot points 74 and which are moved by the motor 42 , gear 46 , and gear elements 50 , 54 to turn the pages . it will be appreciated that the pages 18 may alternatively be turned by control levers which clip onto the pages of the book and which are selectively moved by one or more motors , or other page turning means known in the prior art . however , the present configuration is desirable because it minimizes the number of moving parts . the book may have memory storage thereon as shown in fig6 , such as flash memory or some other circuitry attached to the book or partially embedded in a cover of the book . the memory may be connected to the mobile 10 when the book is attached to the mobile . alternatively , memory may be provided separately and separately connected to the mobile as will be discussed . the mobile 10 is thus optimized for books which have thick pages , such as infants books , as these pages will hold their shape . this allows the mobile to be placed above or adjacent the crib or chair of a child so as to be seen when the child is laying on their back , or to be placed at the side of a crib or chair with the book in an upright position . also shown in fig1 is a mounting device 75 . the mounting device 75 can be used for holding the device to a conventional arm of a mobile , for attachment of the device to the side of a crib , or for holding the device to some other structure , such as a car seat . fig2 illustrates how the mobile 10 typically includes a dome cover 78 which keeps the child from contacting the book 14 or the operational mechanism of the mobile 10 . the cover 78 protects both the child and the mobile from harm or damage . the cover 78 is sized to allow the pages 18 to turn freely without contacting the cover . the cover is preferably a turn - lock cover wherein the cover can be attached by putting it in place and then rotating it a few degrees . this prevents the infant from removing the cover while making removal easy for an adult . of course , other attachment mechanisms can also be used . fig3 shows a front view of the mobile 10 , illustrating how the book 14 is easily viewed from the front of the mobile . the mobile will typically contain a speaker 82 which is used to present the audio recording to the child . alternatively , the means for presenting an audio recording may be detached from the main body of the mobile such as a separate speaker system . additionally , the mobile may also contain a light 86 . the light 86 may be used to illuminate the book 14 when the mobile is in use , allowing the room lights to be off . this may aid in drawing the child &# 39 ; s attention to the book . the light 86 will typically be directed towards the book and not towards the child , and thus may utilize a guard to prevent the light from shining at the child . additionally , the light may be mounted on a positionable arm , such as a flexible arm or an arm with joints therein , to allow the light to be properly aimed at the book . such an arm may allow the light to be better positioned to illuminate the book 14 . the light 86 may then be turned off after the book and audio recording are presented to the child to allow the child to sleep . the light 86 may also function as a nightlight or to present lighting effects such as soft changing colors if desired . the mobile 10 may also include letters , numbers , etc . ( as indicated at 90 ) which may be selectively illuminated as desired . the letters , numbers , etc . may be used as decoration , or may be used to teach the child in combination with books about letters , numbers , etc . the letters or numbers may have individual lights for illumination , or may be connected to a central light via fiber optics , etc . fig4 shows a control panel 94 of the mobile 10 . the control panel 94 may include a media reader 98 , such as a tape reader , for reading a tape , cd , or other media which contains the audio recording corresponding to the book 14 . the control panel 94 may also include a drive or port 106 for connecting flash media 110 or other media which contains the audio recording . a microphone 114 may be provided which allows a user to record the audio recording either to the tape 102 ( or cd , etc . ), flash media 110 , or onboard memory 62 . as such , the control panel 94 may include buttons such as a record bottom 118 , a stop button 122 , or a turn page button 126 which the user presses to indicate that it is time to turn the page . pressing the turn page button 126 may place an indicator signal in the audio recording which signals to the computer controller 58 that it is time to turn the page of the book . the user may thus record their own voice telling the story of a book and play the same to a child . such a configuration would allow any book to be used , and not just books produced with a specialized audio recording . the control panel may have a play button 130 , stop button 134 , or mode button 138 to control the operation of the mobile 10 . the mobile may thus be used to play the book and automatically turn off or revert to a nightlight or other mode afterwards , may be used to stop a book which is being played , may be placed into a music mode , nightlight mode , changing color mode , etc . the mobile 10 may thus be used with different types of books . the books may be conventional children &# 39 ; s story books . alternatively , the books may be books which teach letters , numbers , shapes , language skills , foreign languages , etc . many of such books may be used to educate a child . a photo album may also be used to familiarize a child with relatives . as shown in fig5 , a book 14 may be provided which has thick pages 18 and is sized for use with the mobile 10 , and which has pockets 142 formed on the pages to allow a person to place photographs or the like therein to present the same to the child . the mobile 10 allows a person to use commercially prepared books and audio recordings , and also allows a person to record a customized recording for a desired book . it is appreciated that the voice of a trusted parent may be more calming to a child than a strange voice . the media reader 98 or media drive / port 106 allow a user to record audio recordings on removable media and establish a library of books and recordings , rather than having to record the audio recording for each book every time the book is used . thus , a person may simply buy a handful of flash memory cards or tapes and record audio tracks for a number of books and have these readily available . the mobile of the present invention is desirable for parents of young children . a child may be entertained during waking hours , or the device may be used to help a child get back to sleep in the middle of the night when a parent may otherwise be too exhausted to stop and read a story to the child . the sound of the parent &# 39 ; s voice is reassuring to the child and the parent is able to go back to sleep . there is thus disclosed an improved children &# 39 ; s book mobile / entertainment device . it will be appreciated that numerous changes may be made to the present invention without departing from the scope of the claims . the appended claims are intended to cover such modifications .
a children &# 39 ; s mobile presents a book to a child . the mobile holds the book open and turns the pages at a predetermined time , and may also present an audio recording of the book to the child along with the book so as to ‘ read ’ the book to the child .
