<p>PURPOSE:To simplify the whole constitution, and to make a tape recorder small in size by rotating a cam gear in accordance with an operation, and executing a series of operation control of a constant speed running, a high speed running, a stop and control of a reel mechanism, etc. by a rotational position of this cam gear. CONSTITUTION:A subframe 2 is fixed to a main frame 1 of a tape recorder, and a rotary head 3, a loading motor 4 functioning as a driving source, and a cam gear 5, etc. are attached to the frame 2. Also, tape loading blocks 14, 15 for winding a tape around the periphery of the head 3, and a pack guide member 16 from which the tape is drawn out by the blocks 14, 15 are provided. Moreover, a tape tension applying member for driving a tape pack loaded in the member 16 is provided. In this state, in accordance with an operation, a cam gear 5 is rotated, and by its rotational position, a series of control operations of constant speed running, high speed running, stop and control of the applying member 30, etc. are executed, and the whole constitution is simplified.</p> |
