Abstract
Abstract Tape recorder with built-in program selector for moving a tape to a predetermined point in either the forward or reverse direction and automatically recording or playing back program beginning at that point. The program selector includes a reversible multi-digit counter which is connected to the take-up reel through a reversible gear train. The gear train is arranged in such manner that the counter counts up when the tape moves at the normal speed in the forward direction and counts down when the tape either moves in the reverse direction or moves at the fast speed in the forward direction. When the counter counts down to a predetermined count, tape movement is interrupted, and the tape is transduced at the normal speed in the forward direction.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
125 words
In a tape recorder having electrically energized motive means for moving a tape in forward and reverse direction, said motive means being adapted for selectively moving the tape at first and second speeds in the forward direction, a reversible multi-digit counter forming an integral part of the recorder, reversible drive gear means connecting the counter to the motive means for driving the counter in one direction when the tape is moving at the first speed in the forward direction and driving the counter in the opposite direction when the tape is moving at the second speed in the forward direction, and switch means operably connected to the counter and motive means for interrupting the movement of the tape when the counter reaches a predetermined number.
Claim 2
Dependent Claim
125 words
In a tape recorder having electrically energized motive means for moving a tape in forward and reverse direction, said motive means being adapted for selectively moving the tape at first and second speeds in the forward direction, a reversible multi-digit counter forming an integral part of the recorder, reversible drive gear means connecting the counter to the motive means for driving the counter in one direction when the tape is moving at the first speed in the forward direction and driving the counter in the opposite direction when the tape is moving at the second speed in the forward direction, and switch means operably connected to the counter and motive means for interrupting the movement of the tape when the counter reaches a predetermined number.
Claim 3
Dependent Claim
38 words
A tape recorder as in claim 1 together with means for conditioning the motive means to move the tape at the first speed in the forward direction a predetermined time after the movement of the tape is interrupted.
Claim 4
Dependent Claim
150 words
In a tape recorder having supply and take-up reels and electrically energized motive means for moving a tape in forward and reverse directions between said reels, said motive means being adapted for selectively moving the tape at first and second speeds in the forward direction, a multi-digit counter forming an integral part of the recorder, drive gear means connecting the counter to the motive means for driving said counter in one direction when the tape is moving at the first speed and driving the counter in the opposite direction when the tape is moving at the second speed, switch means operably connected to aid counter and said motive means for interrupting the movement of the tape when said counter reaches a predetermined number, and means for conditioning said motive means to move the tape at the first speed in the forward direction after the movement of the tape is interrupted.
Claim 5
Dependent Claim
150 words
In a tape recorder having supply and take-up reels and electrically energized motive means for moving a tape in forward and reverse directions between said reels, said motive means being adapted for selectively moving the tape at first and second speeds in the forward direction, a multi-digit counter forming an integral part of the recorder, drive gear means connecting the counter to the motive means for driving said counter in one direction when the tape is moving at the first speed and driving the counter in the opposite direction when the tape is moving at the second speed, switch means operably connected to aid counter and said motive means for interrupting the movement of the tape when said counter reaches a predetermined number, and means for conditioning said motive means to move the tape at the first speed in the forward direction after the movement of the tape is interrupted.
Claim 6
Dependent Claim
67 words
A tape recorder as in claim 3 wherein said drive gear means includes an input gear constrained for rotation with the take-up reel, an output gear operably connected to said counter, a drive train providing a predetermined gear ratio between the input and output gears, and means for changing the number of gears in said train while maintaining the ratio between said input and output gears constant.
Claim 7
Dependent Claim
31 words
A tape recorder as in claim 1 wherein the drive gear means is adapted for driving the counter in the opposite direction when the tape is moving in the reverse direction.
Claim 8
Dependent Claim
21 words
A tape recorder as in claim 4 wherein the means for changing the number of gears includes an electrically energized solenoid.
