Thereafter, the arm member 3 comes into contact with a stopper 18 formed on the cabinet main body 1, so that the arm member 3 is stopped. Furthermore, the opening force of the hook spring 7 further rotates the cassette lid 2, and this rotating cassette lid 2 causes the interlocking member (shaft) of the cassette lid 2 to rotate.
When (5a) pushes the interlocking member (wall) (5b) of the cassette holder, the cassette holder 4 rotates, but since the arm member 3 has already stopped, the cassette holder 4 rotates with the arm member 3. It rotates around the fulcrum (support shaft 3a), and the opening angle of the cabinet 1 is larger than that of the cassette lid 2, and the bottom part is lifted up. The state is shown in FIG.

That is, the rod-shaped member of the interlocking member (shaft) (5a) of the cassette lid that is integrally constructed with the cassette lid 2 is the same as the rod-shaped member of the interlocking member (wall) (5b) of the cassette holder that is integrally constructed with the cassette holder 4. The cassette holder 4 is moved along the groove of the U-shaped groove member at the same time as the cassette holder 4 rotates around the support shaft 3a, and the state changes from FIG. 3 to FIG. 4. In the state shown in Fig. 4, the cassette holder 4 is tilted almost horizontally, and the tape cassette 6 stored therein is
can be easily taken out.

Effects of the Invention As is clear from the above description of the embodiments, the present invention includes a cassette lid that can be opened and closed at a fixed angle with respect to the cabinet body, and a biasing means that biases the cassette lid in the opening direction. , having an arm member supported coaxially with the cassette lid body and whose rotation is restricted at an angle smaller than the opening/closing angle of the cassette lid body and a tape cassette holding portion, and rotatably supported by the arm member. the cassette holder, and an interlocking member that operates so that the cassette bolter rotates about a rotation axis with respect to the arm member by the opening force of the cassette lid body by the urging means, even though rotation of the arm member is restricted; When the cassette lid is in the open state, the cassette holder is configured such that the bottom part is lifted up at the cabinet opening by the action of the interlocking member, and the opening angle is larger than that of the cassette lid, and the interlocking member (shaft) of the cassette lid
By providing the interlocking member (wall) of the cassette holder that is perpendicular to the closing direction of the cassette holder or inclined in the closing direction of the cassette lid, the interlocking member (axis) of the cassette lid can be aligned with the cassette holder when closing the cassette lid.
