<p>PURPOSE:To make a lock screw unnecessary by not using the lock screw and dropping a cassette pack consciously on the way of transportation and restoring the cassette pack to the regular state automatically when a user or the like uses it actually. CONSTITUTION:A voltage is applied to a control microcomputer 1 by a power switch 7 to set the control microcomputer 1 and a logic mechanism 4 to the start state. Though a key switch 2 provided on the front of a set is used thereafter to perform the normal operation, production processes such as adjustment are performed in this state on an actual production line. In the last process before shipping, a loading indication is inputted by a loading switch 6, and the mechanism is dropped to the running position after the completion of loading; and thereafter, the power switch 7 is turned off to ship the set in the normal method. When the set is delivered to the user, the user turns on the power switch 7 by the normal method, and the loading state of the set is detected to eject the set, and it is restored to the regular state.</p> |
