Description

[Detailed Description of the Invention] The present invention relates to a lock plate for a push button of a tape recorder or the like.

Conventional lock plates only have the structure shown in Figures 1 and 2, that is, only one side of the lock plate has a hook portion that engages with a push button of a tape recorder, etc.
When trying to provide various functions to the push buttons of a tape recorder, etc., a lock plate must be manufactured each time.

This also means that a mold is required each time, which is also a bottleneck in terms of the cost of tape recorders and the like.

This project was devised to solve this problem, and to put it simply, a hook part that can lock the push button of a tape recorder etc. is formed not only on the front side of the lock plate but also on the back side, so that the type can be typed with one lock plate. It can be used as a lock plate for push buttons of tape recorders with different types, reducing the total mold cost, that is,
This makes it possible to reduce the price of tape recorders and the like.

The present invention will be explained in more detail below based on examples.

Figure 1 shows the front side of the proposed lock plate, Figure 2 shows the reverse side of the lock plate, and Figure 3 shows the lock plate in Figure 1 as seen from the direction of the arrow in the figure. What should be done is that Figure 2 is the lock plate in Figure 1 turned over, so it should be the 3rd one.
4 is a diagram for explaining the engagement relationship between the hook part on the lock plate of FIG. 1 and the push button of a tape recorder, etc.). FIG. 5 is a diagram for explaining the engagement relationship of the push buttons of a tape recorder, etc., which are similarly provided on the lock plate of FIG. 2.

Now, in FIG. 1, the hook part 2 provided on the surface A of the lock plate 1
REC buttons 14 and 5 on the tape recorder, respectively.
If the EW button 15 and the PLAY button 16 are made to correspond to all 16 buttons 17 in sequence, in FIG. In order to press the slope of the fishing part 4 of the lock plate 1 while resisting the biasing force of the spring 12 in the direction, the lock plate 1 has a shaft 1 inserted in the holes 10 and 11.
The lower end projections 16b of all 16 PLAY buttons 16 and all 16 rods 16a of the PLAY buttons 16 go up the slope of the hook 4 of the lock plate 1, and then the lock plate 1 The buttons 9, 130 are returned to their original state by constant biasing force in the clockwise direction r, and all 16 PLAY buttons 16 are locked to the fishing portion 4 of the plate 1, as shown by the dashed line in FIG.

Moreover, when the other buttons are operated in the same way, the heights of the hooks 2 to 5 provided on the lock plate 1 are the same, so that the PLAY button is locked.
All 16 buttons are unlocked.

In this manner, the hooks 2 to 5 provided on the surface A of the lock plate 10 in FIG. 1 function to lock the push buttons of a normal tape recorder.

Next, the hooks 6 to 9 provided on the back side B of the lock plate 1 in FIG. The lock plate 1 in FIG.
Since the lock plate shown in the figure is turned over, the hooks 6 to 9 are the buttons of the tape recorder that are pressed, the REC button 14, the REW button 15, and
They correspond to the PLAY button 16 and the FF button 17 in this order.

In FIG. 3, it can be seen that the lock plates in FIGS. 1 and 2 are reversed.

Next, the case of using the hook parts 6 to 9 provided on the back surface B of the lock plate 1 in FIG. 2 will be explained with reference to FIG.
It can be seen that when only the AY button 16 is pressed, the PLAY button 16 is engaged with the hook portion 8 of the lock plate 1 through the lower end protrusion 16b of the operating rod 16a.

Next, when pushing the FF button 11 with the PLAY button 16 locked, the springs 12 and 13 and the PLAY button 1
The FF
The button 11 is not locked to the hook portion 9.

This is because the height of the hook portion 9 is lower than that of the hook portion 8, and even if the FF button 17 is pressed and the lower end protrusion 17b of the operating rod 17a goes up the slope of the hook portion 9, the spring 130 Compared to the clockwise rotation biasing force, PLAY
The frictional engagement force between the button 16 and the hook portion 8 is much stronger (this engagement force prevents the lock plate 1 from returning to its original state, and when the FF button 17 is released, it is held at hand by the force of the spring 120). It ended up being in a state where the PLA
When the Y button 16 is locked and the FF button 17 is pressed, the tape recorder enters a so-called cue operation.

The same applies to the reverse review operation. In this way, the present project is equipped with hooks on the front and back sides of one lock plate corresponding to the push buttons of a tape recorder, etc., which have different functions, so there are essentially two locking plates in one mold. This also means that different types of lock plates can be manufactured, which leads to a reduction in the total mold cost and the manufacturing cost of tape recorders and the like.
