<p>PURPOSE:To miniaturize the device with a simple constitution effectively utilizing the force of a pressing means and to surely decide the position of a tape pulling-out member by providing the rotary center of a driving arm attached to a driving means on a position different from that for the rotary center of the driving means itself. CONSTITUTION:A tape pulling-out member 8S is moved along a guide groove 5S by the rotation of a driving gear JIS, raised, a position deciding member 9S is reached and further a restraining part 14S is moved away from a link 12S and stopped. At this time, the link 12S is rotated in an arrow A direction by a tension spring 13S, the member 8S is pressed in an arrow B direction, pushed and touched to a member 9S and its position is decided. At this time, the force F of the A direction becomes big, that is, F=Fs X L2/L1, by distances L1 and L2 and the pressing force Fs of the spring 13S. Also, the operation of a tape pulling-out member 8T is the same as this. Thus, the device is miniaturized having a simple constitution, the members 8S and 8T are surely press- contacted to the members 9S and 9T and the position is decided.</p> |
