Abstract

A talking book includes front and back panels. A microcassette tape player and logical circuitry with left and right infrared detectors are located at the top of the back panel. A ring binder is located at the left of the back panel adjacent the spline and below the left and right infrared detectors. A housing below the ring binder carries an infrared source that energizes the left and right infrared detectors. The housing also carries a headset jack. A conduit located beside the ring binder accommodates wires between the logical circuitry and the housing.

Claims

1. Apparatus for providing recorded audible messages related to material being observed on sensible sheets comprising,

means for detachably securing said sensible sheets,

playback means for audibly reproducing sound messages recorded on a recording medium,

means for supporting said playback means and said means for detachably securing said sensible sheets in fixed relationship,

said means for detachably securing allowing easily turning said sheets as in a book to allow said sheets to exchange places between a left pile of sheets and a right pile of sheets and having means for guiding said sheets over a predetermined turning path when moving between said left and right piles,

switching means in fixed relationship to said playback means and said means for detachably securing for providing at least a start signal when a sensible sheet moves from one of said piles to the other,

said switching means comprising left and right switching means for being activated in sequence when a sheet moves over said predetermined turning path from one pile of the other.

and logical circuit means coupled to said left and right switching means for providing said start signal only when said sheet moves in a predetermined forward direction from one of said piles to the other,

said logical circuit means further including means responsive to a sheet moving in a predetermined backward direction from said other of said piles to said one of said piles for providing a stop signal,

means responsive to said stop signal for disabling said playback means and interrupting the production of audible sounds,

and means responsive to said start signal for activating said playback means to produce audible sound associated with a sheet.

2. Apparatus in accordance with claim 1 wherein said switching means further comprises a source of infrared energy and infrared energy detecting means,

said source of infrared energy and said infrared energy detecting means being separated by said predetermined turning path so that the infrared energy beam therebetween is interrupted only when a sensible sheet moves over said predetermined turning path,

said infrared energy detecting means including left and right infrared detecting means for sensing the direction of sheet movement.

3. Apparatus in accordance with claim 1 and further comprising,

means for receiving an audio signal from said playback means that may carry a stop code signal representative of the end of a message associated with a sheet being sensed,

means responsive to said stop code signal for providing a stop signal,

and means responsive to said stop signal for disabling said playback means and terminating the provision of audible sound therefrom.

4. Apparatus for providing recorded audible messages related to material being observed on sensible sheets in accordance with claim 1 and further comprising means for supporting said switching means in noncontacting relationship with said sheets, whereby movement of a sensible sheet from one of said piles to the other activates said switching means without producing mechanical movement of said switching means.

5. Apparatus in accordance with claim 1 wherein said means for detachably securing comprises a ring binder.

6. Apparatus in accordance with claim 5 wherein said playback means comprises a cassette tape player.

7. Apparatus for providing recorded audible messages related to material being observed on sensible sheets comprising,

means for detachably securing said sensible sheets,

playback means for audibly reproducing sound messages recorded on a recording medium,

means for supporting said playback means and said means for detachably securing said sensible sheets in fixed relationship,

said means for detachably securing allowing easily turning said sheets as in a book to allow said sheets to exchange places between a left pile of sheets and a right pile of sheets and having means for guiding said sheets over a predetermined turning path when moving between said left and right piles,

switching means in fixed relationship to said playback means and said means for detachably securing for providing at least a start signal when a sensible sheet moves from one of said piles to the other,

said switching means comprising a source of infrared energy and infrared energy detecting means,

said source of infrared energy and said infrared energy detecting means being separated by said predetermined turning path so that the infrared energy beam therebetween is interrupted only when a sensible sheet moves over said predetermined path,

said switching means further comprising left and right switching means for being activated in sequence when a sheet moves over said predetermined turning path from one pile to the other,

logical circuit means coupled to said left and right switching means for providing said start signal only when said sheet moves in a predetermined forward direction from one of said piles to the other,

and means responsive to said start signal for activating said playback means to produce audible sound associated with a sheet.

8. Apparatus for providing recorded audible messages related to material being observed on sensible sheets comprising,

means for detachably securing said sensible sheets,

playback means for audibly reproducing sound messages recorded on a recording medium,

means for supporting said playback means and said means for detachably securing said sensible sheets in fixed relationship,

said means for detachably securing allowing easily turning said sheets as in a book to allow said sheets to exchange places between a left pile of sheets and a right pile of sheets and having means for guiding said sheets over a predetermined turning path when moving between left and right piles,

switching means in fixed relationship to said playback means and said means for detachably securing for providing at least a start signal in response to movement of a sensible sheet from one of said piles to the other pile without producing any movement of the switching means,

means responsive to said start signal for activating said playback means to produce audible sound associated with a sheet,

and means for supporting said switching means in noncontacting relationship with said sheets.

9. Apparatus for providing recorded audible messages related to material being observed on sensible sheets in accordance with claim 8,

said switching means comprising left and right switching means for being activated in sequence when a sheet moves over said predetermined turning path from one pile to the other and further comprising,

logical circuit means coupled to said left and right switching means for providing said start signal only when said sheet moves in a predetermined forward direction from one of said piles to the other.
