Abstract
Abstract Educational apparatus in the form of a recording/reproducing unit accommodates a record media comparable in size to the familiar IBM tabulation card. The media has printed information on one side such as questions and answers, circuit diagrams, etc. that are visible to the user when in operating position and recorded information on the opposite side positioned for scanning by a transducer during playback and record modes. Preferably, the media has either the visible information or the magnetically stored information, or both, divided into blocks of convenient size representing different questions, multiple choice answers, or the like, with the recorded information and the visible information correlated with one another. Programming structures are provided in the apparatus enabling the user to roughly scan toward a selected block of information on the media but defining a plurality of program stops arranged adjacent the beginning of each of the blocks of information and facilitating the positioning of the transducer with respect to the first track in a selected block.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
193 words
Apparatus for selecting a desired location from among a plurality of locations on a record media, comprising: program means associated with said media, said program means having a plurality of program stops correlated with and corresponding in number to said plurality of locations, said program stops being oriented for engagement only from a preferred engaging direction; and scanning means in said apparatus, said scanning means being arranged for movement both in said preferred engaging direction and in a nonengaging direction opposite to said preferred direction, and having a member normally engageable with individual program stops only when said scanning means is moved in said preferred engaging direction; means for moving said scanning means at least in said preferred direction so that said engageable member moves into engagement with a selected one of said program stops corresponding to a said desired location and for moving said scanning means in said opposite nonengaging direction for manual random scanning; and means for selectively positioning said engaging member out of engaging relation with said program stops to enable nonengaging random scanning by said scanning means when moved in said preferred direction, as well as said opposite direction.
Claim 2
Dependent Claim
193 words
Apparatus for selecting a desired location from among a plurality of locations on a record media, comprising: program means associated with said media, said program means having a plurality of program stops correlated with and corresponding in number to said plurality of locations, said program stops being oriented for engagement only from a preferred engaging direction; and scanning means in said apparatus, said scanning means being arranged for movement both in said preferred engaging direction and in a nonengaging direction opposite to said preferred direction, and having a member normally engageable with individual program stops only when said scanning means is moved in said preferred engaging direction; means for moving said scanning means at least in said preferred direction so that said engageable member moves into engagement with a selected one of said program stops corresponding to a said desired location and for moving said scanning means in said opposite nonengaging direction for manual random scanning; and means for selectively positioning said engaging member out of engaging relation with said program stops to enable nonengaging random scanning by said scanning means when moved in said preferred direction, as well as said opposite direction.
Claim 3
Dependent Claim
45 words
The apparatus of claim 1 wherein: said program means comprises a toothed rack having program stops in the form of individual teeth, each formed for engagement on a selective basis by said scanning means only when said scanning means is moved in said preferred direction.
Claim 4
Dependent Claim
45 words
The apparatus of claim 1 wherein each of said program stops is positioned on a periodic basis to encompass two or more locations on a record media, therefore defining a block of information such as a question, an answer, a recording location, or the like.
Claim 5
Dependent Claim
44 words
The apparatus of claim 2 wherein said locations are further divided into a plurality of tracks and further comprising: escapement means associated with said program means and normally engaged with said scanning means for effecting escapement of said scanning means on a track-by-track basis.
Claim 6
Dependent Claim
39 words
The apparatus of claim 4 further comprising: manually operable release means for concurrently diSengaging said program means and said escapement means to enable free movement of said scanning means in relation to said media, as desired by the user.
