PURPOSE:To hold a cassette correctly and easily, by charging spring force in pressing in the cassette inserted in a holder, and using the charged force to perform following inserting operation and the retaining of the holder at a normal loading position. CONSTITUTION:When the cassette 1 is pressed in from an insertion entrance which is not shown in a figure, the end part of the cassette 1 abuts on the contacting part 7 of a moving body 8 and when it is further pressed in, the moving body moves forth against springs 20 and 22 along guide grooves 16 and 17. A guide pin 10 reaches the front end of the groove 16, the moving body 8 is rotated counterclockwise through the operation of the springs 20 and 22 locked by pins 12 and 13 each at one end, and the body 8 is locked by a lock piece 24 fixed to a solenoid 9. A driven body 18 is energized by the spring 20 at the same time, but stopped by a stop lever 26. The moving body 8 once finishes moving forth is released from being atopped and the driven body 18 moves forth by being energized by the spring 20 to rotate gears 30, 31, and 32, thereby loading the cassette 1 at the normal loading position. Thus, the cassette is loaded accuratey. |
