<p>PURPOSE:To prevent a careless operation in the middle of loading and unloading a cassette magazine by positioning the operational button of the 1st main body at an operable place when the 2nd main body comes to a standby position and setting said button inoperable at a separate place. CONSTITUTION:The 1st main body 1 has a variety of operational buttons 9, and the 2nd main body 2 has a through hole 10 at a position opposite to said buttons 9. The 2nd main body 2 is made slidable in a stroke range where the operational buttons 9 installed on the 1st main body 1 can be visible or invisible according as the 2nd main body 2 changes its attitude between the 1st and 2nd states. Namely, the 2nd main body 2 moves so as to reduce with respect to the 1st main body 1. The operational buttons 9 installed on the 1st main body 1 protrude from the through hole 10 installed on the 2nd main body 12 when a pinch roller is brought into a standby position on a capstan spindle, and the operational buttons 9 become operable. On the other hand, when the pinch roller is separated from the capstan spindle, the operational buttons 9 become inoperable.</p> |
