<p>PURPOSE:To correspond to both upper opening and lower opening by providing a linking arm between a cam arm to be turned by an operating piece to be interlocked with a holder, which is provided in the almost center of a door to be supported by the upper or lower direction of a cassette inserting port, and an opener to execute the opening and closing of the door. CONSTITUTION:An operating piece 24a such as a pin, etc., is provided in a position to be almost coincident to the center of a tape cassette A which is inserted to the inserting port of a door 27 to be supported by the upper or lower direction of the cassette inserting port. Then, a linking arm 29 is provided between a cam arm 26, which is turned by the operating piece 24a, and an opener 28 which is supported and executes the opening and closing of the door by the turn. Accordingly, by changing the support position of the opener 28 up and down and changing the linking position of the linking arm 29, which links the opener 28 and cam arm 26, up and down to the support position of the opener 28, the motion of the opener 28 can be made reverse to the motion of the cam arm 26. Thus, the door can correspond to the both upper opening and lower opening.</p> |
