Abstract
Abstract Apparatus which can be attached to or incorporated in a tape recorder for repeated automatic reproduction of information stored on a selected portion of magnetic wire or tape has a start button which is depressed to start a first counter when the user detects the foremost part of reproduction of information on the selected portion of wire or tape, and a stop button which is depressed to start a second counter when the user detects the end of information which is stored on the selected portion of wire or tape. At the same time the stop button causes a reversal in the direction of transport of the wire or tape and a movement of the sound head away from the wire or tape. The first counter is driven by the supply reel for the wire or tape during forward transport, and the second counter is driven while the supply reel rotates in a direction to collect the wire or tape whereby the first counter is reset to zero when the second counter assumes a position corresponding to that of the first counter at the end of reproduction of selected information. The resetting of first counter to zero position results in a return movement of the sound head into engagement with the wire or tape and in rotation of the takeup reel in a direction to collect the wire or tape. When the second counter is reset to zero, it automatically reverses the direction of movement of the wire or tape and causes the sound head to move away from the wire or tape. The counters may be operated mechanically or each thereof may constitute a digital counter.
