Description

[Detailed Description of the Invention] The present invention is designed so that the cassette can be removed without any problems such as the magnetic head hitting the cassette even if the eject lever is operated directly during playback without stopping the playback. This invention relates to an ejection device for a tape recorder.

Some cassette type tape recorders have a cassette holder provided in a cassette storage section that can be rotated together with the cassette held therein, in order to facilitate the installation and removal of the cassette. When removing a cassette in such a device, the cassette holder is rotated by the force of a spring, but if the eject lever is operated during recording or playback when a magnetic head is fitted to the cassette. When the lock is released and the cassette holder is rotated in the opening direction by the force of the spring, the magnetic head may hit the cassette and be damaged. Therefore, some devices prevent the eject lever from being operated during the recording or playback state, or some devices first stop the eject lever when the eject lever is operated, then release the lock and eject. However, the former is troublesome to operate, and the latter cannot secure a large amount of lock between the eject lever and the cassette holder, so it is difficult to eject the cassette after it has stopped. When I started, the magnetic head sometimes hit the cassette.

Therefore, the present invention makes the movement of the eject lever different by 90 degrees when locking the cassette holder and when releasing the lock, so that in the unlikely event that the eject lever is operated during recording or playback, etc. However, the present invention provides an ejecting device for a tape recorder which is ejected after performing an operation such as stopping.

The present invention will be explained below with reference to the drawings. Reference numeral 1 denotes a cassette holder having a cassette holding part 2, and metal fittings 3, 3 attached to the rear end are pivotally supported on a base plate 5 by pins 4, 4. It is rotatably attached to the cassette storage chamber. Reference numeral 6 denotes a leaf spring that always urges the cassette holder 1 in the opening direction; 7, the cassette holder 1 is connected to the base plate 5 by fitting the pins 8, 8 projected from the base plate 5 into the long grooves 9, 9; It is an eject lever mounted so that it can slide in a parallel direction, and has a locking part 11 that protrudes from a frame-shaped part 10 formed by an opening formed in order to bend in a direction perpendicular to the cassette holder 1, and a long groove 12 of the board 5. It has a knob 13 that is more protruding. The ejection lever 7 is biased to the state shown in the figure by a spring 14, and the locking portion 11 has an inclined surface 15, and locks with the sloped locking piece 16 on the side surface of the cassette holder 1. is facilitated. A slide base 17 is slid by a plunger 18, and a magnetic head 19 is attached thereto. A reed switch 20 is turned on and off by the ejection lever 7, and excites the plunger 18.

Next, the operation of the present invention will be explained. First, in order to install the cassette 21 into the storage chamber of the tape recorder, push the knob 13 in the direction of the arrow a and slide the ejection lever 7. Stop part 1
1 and the locking piece 16, the cassette holder 1 is rotated in the opening direction by the urging force of the leaf spring 6. In this state, the cassette 21 is inserted through the front opening of the cassette holder 1, and the cassette 21 is held in the cassette holder 1. When the cassette holder 1 is subsequently rotated in the closing direction, the inclined locking piece 16 on the side surface of the cassette holder 1 comes into contact with the locking portion 11 of the eject lever 7. Then, the frame-shaped part 10 is bent and the locking part 11 moves in the direction of arrow b, and when it is pushed further, the locking piece 16 goes beyond the tip of the locking part 11 and enters below. In this state, cassette 2
The reel drive shaft meshes with the hub of 1, the cassette 21 is installed in the storage chamber, and the cassette holder 1 is operated by the urging force of the leaf spring 6 as the locking piece 16 locks with the locking portion 11. is maintained in that state against the

Next, for example, when a regeneration lever (not shown) is operated to enter the regeneration state, the power switch 21 is turned on. At this time, the reed switch 20 is turned on, so the voltage from the battery 22 is applied to the plunger 1.
8 and excites the plunger 18. Then, the slide base 17 is slid, and the magnetic head 19 is fitted into the cassette 1.
9 can be brought into contact with the tape 23. Therefore, as the tape 23 is run, music recorded on the tape 23 is played back.

When the playback is completed and the cassette 21 is taken out, a stop lever (not shown) is operated to stop it, and the power switch 20 is turned off and the plunger 1 is turned off.
8 is de-energized, the slide base 17 is returned by the force of the spring 24, and the magnetic head 19 is removed from the cassette 21. However, in the present invention, the cassette 21 can be ejected without any problem even when the eject lever 7 is directly operated from the playback state.

That is, when the eject lever 7 is pulled in the direction of arrow a against the biasing force of the spring 14, the leaf switch 20 is first turned off, the plunger 18 is de-energized, and when the slide base 17 is returned to its original position by the biasing force of the spring 24. , the magnetic head 19 is connected to the cassette 2
It is separated from 1. At this time, the lengths of the locking piece 16 and the engaging part 11 are set so that the locking piece 16 and the engaging part 11 are still engaged. After the leaf switch 20 is turned off, when the eject lever 7 is further pulled, the locking piece 16 and the locking portion 11
Since the cassette holder 1 is rotated in the opening direction by the biasing force of the leaf spring 6, the cassette 21 can be taken out from the opening of the cassette holder 1.

The tape recorder eject device of the present invention is
As mentioned above, when locking or releasing the cassette holder with the eject lever, the movements of the eject lever are made to differ by 90 degrees, so the movement of the eject lever is small when locking and when releasing. The movement of the eject lever can be increased. Therefore, when an eject operation is performed in the reproducing state, the cassette holder and the eject lever can be unlocked after first being brought to a halt state, thereby providing a simple eject device.
