Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a tape recorder equipped with a spring-back operation button that can be maintained in an activated position by hand and automatically returned to a non-activated position by a spring when released.

Small tape recorders such as micro cassette recorders are often operated by holding the main unit in the hand.
For this reason, springback type fast forward and cue buttons are generally used.

On the other hand, there may be times when it is more convenient to place such a tape recorder on a desk or the like for fast forwarding or cueing, and in such cases it is desirable to lock the button in this position.

However, until now, no mechanism has been developed that allows locking in the operating position and automatic return, which is a spring-back function, to be performed with a simple structure and without malfunction.

Therefore, this invention was devised in view of the above circumstances, and its purpose is to create a cassette tape with a simple spring-back operation button that is reliable and has less risk of malfunction. The purpose is to provide a recorder.

A cassette tape recorder according to an embodiment of the invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a tape recorder with the cassette lid in the open position, and in the figure, reference numeral 1 designates the main body of the tape recorder, which is large enough to be held and operated with one hand.

A cassette lid 3 whose one end is rotatably supported by a hinge 2 is provided on the upper surface of the main body 1.

A cassette storage chamber 4 is formed below the cassette lid 3, and the cassette is stored or taken out in the illustrated state in which the cassette lid 3 is in the open position.

A first operating button 5 is provided on one side of the main body 1 and is movable in the direction of arrow a and the opposite direction, and when this operating button 5 is slid in the direction of arrow a, it is in the play position. ,
When it is slid in the direction opposite to the arrow, it is held at the rewind position, and in the middle thereof, it is held at the stop position, so that it performs its respective functions.

Further, on the upper side of the main body 1, a second operation button, that is, a fast forward and cue button 6 is provided.

This second operation button 6 is held in the operating position when moved in the direction of the arrow, and is automatically returned from this operating position to the return position by a spring (not shown).

Further, when the second operation button 6 is held in the operation position when the first operation button 5 is in the stop position, it performs a fast forward function, and when the first operation button 5 is held in the play position and the rewind position, respectively. At some point, when it is slid into the active position, it performs the cue function and review function.

The tape recorder configured as described above is further provided with a locking mechanism 7 for locking the second operation button 6 in its operating position as required.

This locking mechanism 7 is inserted from the upper side of the tape recorder main body 1.
It has a lock pin 9 slidably inserted into a long hole 8 extending over the upper side of the cassette storage chamber 4 .

The lower end of this lock pin 9 faces the cassette storage chamber 4, and the upper end faces the lower surface of the second operation button 6. Normally, the compression spring 10 causes the lower end to face the cassette storage chamber 4.
It is biased downward so that it protrudes inward.

On the other hand, a lid spring 11 is provided protruding from the tip of the cassette lid 3 to lock the closed position of the cassette lid 3.

When the cassette lid 3 is closed, this lid pull 11
The cassette lid 3 is locked from the closed position by coming into pressure contact with the base end of the lock pin 9, sliding the pin 9 upward against the biasing force of the compression spring 10, and then engaging with the base end. It looks like this.

Further, a lock recess 12 is provided on the lower end surface of the second operation button 6.
is formed, and the lock pin 9 is connected to the lid springag 1.
When the second operation button 6 is moved to the operating position while being pressed upward by the button 1, the tip of the lock pin 9 is inserted and the operating position is locked.

In the cassette tape recorder having the above configuration, when the cassette lid 3 is held in the closed position, the lid spring 11 provided at the tip of the cassette lid 3 elastically presses the lock pin 9 upward, and the tip of the cassette lid 3 is held at the closed position. The second button is located on the bottom surface of the operation button 6.
They are brought into contact as shown in Figure A and Figure 2B.

In this state, when the operation button 6 is slid with a finger in the direction of the arrow to bring it to the operating position, the tip of the lock pin 9 is inserted into the recess 12 by the elastic force of the lid spring 11. As shown in FIGS. 3A and 3B, the second operating button 6 is locked in the operating position.

As a result, even if the finger is removed from the operating button 6, the operating button 6 will not be returned to its original non-operating position by a spring (not shown).

Therefore, depending on the position of the first operation button 5, the fast forward function, cue function, and review function are selectively performed.

In the above embodiment, the lock pin is pressed by the lid spring for locking the cassette lid in the closed position, but a pressing member may be provided separately from the lid spring.

Further, the locking mechanism is not limited to the above mechanism as long as it operates in response to opening and closing of the cassette lid and locks the operation button in the operating position.

The operation buttons to be locked are not limited to fast forward and cue buttons, but may also perform other functions.

As explained above, in the cassette tape recorder according to this invention, the springback type operation button is set to the pin state and unlocked state according to the opening/closing operation of the cassette lid, so there is less risk of erroneous operation, and the structure is simple. Switching between the above two states can be easily and reliably performed.
