Description

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

Conventional Structure and Problems In recent years, cassette tape recorders have become more compact and electronic, and the timing at which the head board to which the recording/playback head is attached has been retracted has tended to be delayed.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 tape cassette take-out hook 31 integrally formed with an opening/closing lid 30. Therefore, when taking out the tape cassette 32, the tape cassette 32 is pulled out at the same time as the opening operation of the opening/closing lid 30 begins, and the tape cassette 30 is pulled out before the head board retreats, so that the tape cassette 32 is not attached to the head etc. The problem was that it got stuck and could not be removed. As a method of delaying the timing of taking out the tape cassette, it is possible to increase the play space 33 between the stored tape cassette and the hook as shown by the imaginary line in FIG. However, there is a limit to the size of such a play space, and it cannot be applied.

OBJECTS OF THE INVENTION An object of the present invention is to provide a tape cassette ejecting device that can arbitrarily set the timing for ejecting a tape cassette without increasing the play space of the hooking claw that comes into contact with 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 a tape cassette, which is rotatably attached to the inner surface of the opening/closing lid, and the eject lever and the opening/closing lid are connected together. It is characterized by being constructed so that it can be joined with arbitrary play.

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

1 and 2 show a state in which a tape cassette 8 is attached, and a lid mounting plate 7 is provided with bent portions 18 that are pivotally supported on a rotation shaft 17 at both ends of a mounting plate 6 attached to a mechanism board 5. It consists of

An eject lever 11 is attached, which has a flange portion 15 rotatably fitted to the shaft 14 of the lid mounting plate 7, is provided with a hook 12 for the tape cassette 8, and is provided with a hook protrusion 13.

On the other hand, the eject lever 11 is attached to the inner surface of the opening/closing lid 4 fixed to the lid mounting plate 7 with screws or the like.
A hook protrusion 1 is placed at a position corresponding to the hook protrusion 13 of
A rib 9 having a diameter of 0 is integrally provided. At this time, as shown in FIG. 2, a play space 16 is provided between the eject lever 11 and the rib 9.

FIGS. 3 and 4 show a state in which the opening/closing lid 4 has begun to be opened. The hooking protrusion 10 of the rib 9, which is provided integrally with the opening/closing lid 4, moves simultaneously with the rotation of the opening/closing lid 4 about the shaft 17. The eject lever 11 moves only by the amount of movement of the rotating shaft 14, and the eject lever 1
Although the play space 16 formed by the first hooking protrusion 13 is reduced, it is still secured and 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, and the tape cassette 8 is pulled out by the hook 12 of the eject lever 11 for taking out the tape cassette.

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

Effects of the Invention As described above, according to the present invention, there is no need to provide a hook on the lower surface of the tape cassette in order to delay the timing at which the tape cassette starts to be pulled out when the tape cassette is taken out. Since the timing for taking out the tape cassette can be arbitrarily set by arranging the tape cassette only in a certain space, it has the advantage that it is extremely useful for miniaturization.

Claims (1)

[Claims] 1. An eject lever 11 having a hook 12 and a hook protrusion 13 for ejecting a tape cassette is rotatably attached to the inner surface of the open/close cover 4 which is rotatably supported, and when the open/close cover 4 is opened. It has a rib 9 that is integrally provided with the opening/closing lid 4 and forming a hooking protrusion 10 provided opposite to the protruding piece 13 to have a play space, and the opening/closing lid 4 is provided at a certain angle or more. A tape cassette ejecting device characterized in that when opened, the hook protrusion 13 and the hook protrusion 10 come into contact with each other and the eject lever 11 is pulled up.
