る。 Next, the operation of the eject mechanism will be explained. First, in Fig. 1, the eject lever 2
When the button 2a at the upper end is pushed in the direction of the arrow, the ejector lever 2 slides downward and the lock pin 2b is disengaged from the engagement cam portion 4a of the slider 4. When the lock pin 2b is disengaged from the engaging cam portion 4a, the slider 4 slides in the direction of the arrow by the tension spring 5, and as shown in FIG. 4b pushes the protrusion 6a to move the head stand 6 to the eject position. Further, as the slider 4 moves, the release claw 4c at its tip pushes the lower part of the lock arm 7 to the right, causing the lock arm 7 to rotate counterclockwise (indicated by the arrow) against the tension spring 8. . When the lock arm 7 rotates, the lock claw 7a at the upper end of the lock arm 7 is removed from the protrusion 9a of the cassette holder 9.
The cassette holder 9 is rotated in the eject direction (arrow) as shown in FIG. 3 by the action of the torsion spring 12, and the cassette 11 can be taken out.

引張ばね８により元の位置に復帰している。 As the cassette boulder 9 rotates, the hanging piece 9b integrated with it also rotates clockwise, and the roller 13 pushes the slider 4 in contact with it to the left, so that the slider 4 It is pushed back in the direction of the arrow in Figure 3. When the slider 4 returns to its original position, the ejector lever 2 is raised again by the action of the tension spring 3 so that its engaging cam portion 4a engages with the lock pin 2b again. Further, as the slider 4 returns, the release claw 4c also moves to the left and separates from the lock arm 7, so that the lock arm 7 is also returned to its original position by the tension spring 8.
従つて、開放しているカセツトホルダー９を手

図の状態にロツクする。 Therefore, when the open cassette holder 9 is pushed closed by hand, the protruding piece 9 comes into contact with the slope 7a' of the lock claw 7a, causing the lock arm 7 to rotate slightly counterclockwise and locking the lock claw 7a. After passing through this point, the lock claw 7a returns again and fully engages with the protrusion 9, thereby moving the cassette holder 9 to the first position.
Lock in the state shown.

一側に配置してコンパクトにまとめられる利点が
ある。 As described above, in the present invention, since each member is attached to slide or rotate directly on the chassis, not only is the operation reliable and there are few failures, but also the ejecting operation of the cassette holder allows
Since the slider and other members are automatically returned to their original positions, a special operating mechanism for return is not required, and an eject mechanism with a simple and compact structure can be obtained. In addition, since the ejector lever is a push type, the hole in the cover through which the lever is passed can be the same size as the cross-sectional shape of the lever, eliminating the need for unnecessary slits and improving the appearance. There is no need to worry about objects or dirt getting inside through the slits in which the tape recorder moves, and there is also the advantage that all mechanical members can be arranged on one side of the tape recorder, making it compact.
