<p>PURPOSE:To prevent a device or tape from being damaged due to missloading or incomplete loading, by providing a movable member which takes different positions for incomplete loading and complete loading of a cassette in order to make the cassette closing impossible through the movable member, if it is in incomplete position. CONSTITUTION:A cassette securing lever 8 and stop lever 10 are supported by an axis 7 of a cassette holding part 2. They are turned together by a spring 12 and forcibly moved in counterclockwise direction by a spring 11. If a cassette 25 is inserted, a securing part 8a of the lever 8 is pushed and turned in clockwise direction, and the lever 10 turns in the same way. If the holding part 2 is tried to be closed in this state, an end 10a of the lever 10 touches a stopping part 1a of a main body 1 so that the holding part can not be closed. If the cassette 25 is completely inserted, the lever 10 turns in counterclockwise direction and does not touch the stopping part 1a so that the closing is possible. As the result, miss- loading or incomplete loading is prevented so that the device and tape are prevented from being damaged.</p> |
