<p>PURPOSE:To execute various operations by a simple constitution, by providing three electromagnetic plungers, two levers and prescribed members to be driven, and selectively using an electromagnetic plunger. CONSTITUTION:This device is equipped with the first and second electromagnetic plungers 45b, 45a, the first and second levers 37b, 37a which are driven by said plungers, and the third elecromagnetic plunger 88. Also, it is provided with members to be driven, consisting of slide plated 52a, 52b. When recording or reproducing, an arm 41b is rotated counterclockwise and an arm 39b clockwise, respectively, by exciting the plungers 45b, 88, the lever 37b is moved almost in parallel, the slide plate 52b is moved upward, a reel base is driven, a head is made to contact by pressure, and recording or reproducing is executed. In case a tape is made to run at a constant speed in the opposite direction, the plungers 45a, 88 are excited. In this way, various operations such as fast-forward and turn-back poses are executed by selectively using three plungers 45a, 45b and 88.</p> |
