Abstract

PURPOSE:To miniaturize a tape cassette unloading device by connecting an ejection lever to a cover with an optional play to increase a play space of a hook pawl touching the lower surface side of a tape cassette. CONSTITUTION:A play space 16 is secured between an ejection lever 11 and a rib 9 which is set in a body with a cover 4. A hook projection 10 of the rib 9 moves concurrently with turning of the cover 4 carried out centering on a shaft 17. In this case, however, the lever 11 attached to a rotary shaft 14 of a folded part 18 of a cover attachment plate 7 moves by just an amount equivalent to the shift of the shaft 14. Thus the space 16 consisting of the projection 10 and a hook projection bar 13 of the lever 11 is reduced but still secured. Thus it is impossible to obtain the power to pull out a tape cassette 8. When the cover 4 is turned and opened more, the space 16 is eliminated. Then the cassette 8 is pulled out by a hook pawl 12 for extraction of tape cassette provided to the lever 11.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a tape cassette ejecting device in a cassette tape recorder.

Conventional Structures and Problems In recent years, cassette tape recorders have become more compact and electronic, and the timing at which the head substrate to which the recording/playback head is mounted has been retracted has tended to be delayed.

FIG. 7 shows a conventional tape cassette ejecting device.

This tape cassette take-out device has a claw 31 as a tape cassette take-out hook integrated with the opening/closing lid 3o.

Therefore, when the tape cassette turtle 32 is taken out, the tape cassette 3
However, since the tape cassette 30 is pulled out before the head board retreats, the tape cassette 32 gets caught on the head and cannot be taken out. As a method of delaying the timing of taking out the tape cassette, it is possible to make the tape cassette and the hook that are housed as shown by the imaginary line in FIG. However, there is a limit to the size of such a play space, and it could not be applied.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a tape cassette ejecting device that allows the timing of ejecting the tape cassette to be arbitrarily set without increasing the play space for the hook that contacts the lower surface of the tape cassette. do.

Structure of the Invention In order to achieve the above object, the tape cassette ejecting device of the present invention includes an eject lever having a hook for ejecting the tape cassette, which is rotatably attached to the inner surface of the opening/closing lid;
A feature of the present invention is that the eject lever and the opening/closing lid are configured to be connected with a certain amount of play.

Description of examples 1 to 6 show one embodiment of the present invention.

Figures 1 and 2 show the state in which the tape cassette 8 is installed.
As shown, the lid mounting plate 7 is provided with bent portions 18 that are pivotally supported by rotating shafts 17 at both ends of the mounting plate 6 to which the mechanism board 5vC is attached.

The eject lever 1 has a flange portion 15 that rotatably fits on the shaft 14 of the lid mounting plate 7, a hook 12 for the tape cassette 8, and a protrusion 13 for the hook.
Install 1.

On the other hand, on the inner surface of the opening/closing lid 4 fixed to the lid mounting plate 7 with screws or the like, the eject lever 11 is hooked onto a protruding piece 1.
At a position corresponding to 3, the hook is integrally provided with a lip 9 having a protrusion 1o. At this time, as shown in FIG. 2, a play space 16 is provided between the eject lever 11 and the lip 9.

FIGS. 3 and 4 show a state in which the opening/closing lid 4 has begun to be opened. The protrusion 1o of the rib 9 provided integrally with the opening/closing lid 4 moves at the same time as the opening/closing lid 4 rotates around the axis 17, but
The eject lever 11 attached to the eject lever 11 moves only by the amount of movement of the rotating shaft 14, and the above-mentioned hook is formed by the protrusion 10 and the protrusion piece 13. Although the play space 16 is reduced, it is still secured. Therefore, it cannot be used as a force to pull out the tape cassette 8. When the opening/closing lid 4 is further rotated and opened, the play space 16 disappears.
Tape cassette 7) of eject lever 11 The tape cassette 8 is pulled out by the ejecting hook 12.

5 and 6 show the state in which the tape cassette 8 is pulled out.

Advantages of the Invention As described above, according to the present invention, there is no need to provide a hook on the bottom side of the tape cassette in order to delay the timing at which the tape cassette starts to be pulled out when taking out the tape cassette. Since the timing for taking out the tape cassette can be arbitrarily set by disposing the tape cassette only in the space of
