<p>PURPOSE:To diminish the area in a moving course of an arm and to promote the degree of freedom of disposing parts and then to miniaturize the equipment by moving the arm provided with a tape drawing post in its lengthwise direction after turning the arm to a prescribed position. CONSTITUTION:When a cam plate 28 is driven to rotate, the arm 22 under the contact state with a protrusion 30 of the cam plate 28 due to energizing force of a spring 27 is turned together with the cam plate 28 around a supporting shaft 20. Then, when the arm 22 is turned to the prescribed position, the arm 22 is brought into contact with a stopper 29 provided on a substrate to be regulated in its turning position. Under such a circumstance, when the cam plate 28 is rotated, a pin 25 is pushed by a cam groove 24 formed in a spiral shape toward the outer circumference, the arm 2 is slid in its lengthwise direction against the spring 27, and the tape drawing post 23 is operated to draw out a tape from a cassette.</p> |
