Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a push button device for a tape recorder, and in particular, by detecting an unrecorded portion of a plurality of songs recorded on a magnetic tape, the present invention automatically switches from high-speed forwarding to a playback state, and then switches to the next playback state. In a tape recorder that can automatically play back a song from the beginning, a press button of the tape recorder can be used to easily perform a queue operation and a review operation in addition to the operation of detecting an interval depending on the operation state of the button. It provides equipment.

Conventional tape recorders capable of performing song interval detection operations are only capable of fast forwarding and rewinding operations, and are not capable of performing cue or review operations. According to the invention,
All of the above operations are possible by adding only one button compared to conventional tape recorders, and operability is significantly improved compared to conventional tape recorders.

Hereinafter, the present invention will be explained in detail according to embodiments shown in the drawings.

Figures 1a and 1b are external views of a tape recorder equipped with a push button device of the present invention, and Figures 2 and below are internal configuration diagrams thereof. Below, these drawings will be explained.

In FIG. 5, 1 is a slide plate that can be slid in the directions of arrows A and B, 2 is a slide plate that can be slid only in the direction of arrow A, and 3 is a slide plate that can be slid only in the direction of arrow B.
C is in contact with an angle portion of a frame (not shown), so the slide plate 2 cannot slide in the direction opposite to arrow A. Furthermore, since one end 3a of the slide plate 3 is in contact with an angle portion of a frame (not shown), it cannot slide in the direction opposite to the arrow B. ), the slide plate 1 has a pin 1a and a notch 1
b, and the slide plate 2 is provided with pins 2a, 2b.
A pin 2b provided in the slide plate 2 is located in a notch 1b provided in the slide plate 1, and a tension spring is installed between the pin 1a of the slide plate 1 and the pin 2a of the slide plate 2. 23, and a tension spring 21 is provided between one end 2c of the slide plate 2 and the angle portion of the frame (not shown).
However, a tension spring 22 is also provided between one end 3a of the slide plate 3 and an angle portion of the frame (not shown). Due to the action of the tension springs 21 and 22,
One end 2c of slide plate 2 and one end 3 of slide plate 3
A is always in contact with an angle portion of the frame (not shown) unless the operation button is pressed. Furthermore, the slide plate 1 is always pulled in the direction of arrow A by the action of a tension spring 23 provided between the pin 1a of the slide plate 1 and the pin 2a of the slide plate 2, and therefore the slide plate 1 is constantly pulled in the direction of arrow A. Notch 1 of plate 1
The side portion 1c of b is always in pressure contact unless the operation button is pressed. When the slide plate 2 slides in the direction of arrow A, the slide plate 1 also becomes integral with the slide plate 2 due to the action of the tension spring 23 provided between the pin 2a of the slide plate 2 and the pin 1a of the slide plate 1. Move in the direction of arrow A. When slide plate 1 slides in the direction of arrow A, slide plate 1
Since the side part 1c of the notch 1b provided in the slide plate 2 pushes the pin 2b provided in the slide plate 2, the slide plate 2 also moves in the direction of arrow A together with the slide plate 1. Note that even if the slide plate 1 slides in the direction of arrow B, the slide plate 2
It cannot move in the direction of arrow B because point c is in contact with an angle portion of the frame (not shown).

The slide plate 3 can slide only in the direction B, completely independent of the slides 1 and 2. The slide plate 1 has protrusions 11, 12, 13 provided to obtain each operating state, the slide plate 2 also has protrusions 14, 15, and the slide plate 3 has protrusions 16, 1.

The apparatus of the present invention is constructed as described above and operates as follows. In addition to FIGS. 1 to 5, FIGS. 6 and subsequent figures will be used to explain the operation.

FIG. 6 shows the state in which the play button 5 is pressed. When each button is positioned in the state shown in FIG. 5, as the play button 5 is pushed in the direction of arrow C,
The pin 5a provided on the play button 5 moves along the protrusion 17 of the slide plate 3 shown in FIG. When the pin 5a moves along the protrusion 17, the slide plate 3
is slid in the direction of arrow B. At this time, the slide plates 1 and 2 do not move at all.

Then, as shown in FIG. 6, the pin 5a of the play button 5 engages with the hook portion 17a of the protrusion 17 of the slide plate 3. The play button 5 is thereby maintained in the pressed state, and during this time, each mechanism of the tape recorder is interlocked so that the tape is fed at the speed of the play state.

Further, when the fast forward button 6 is pressed while the play button 5 in FIG. 6 is pressed, a cue operation is obtained. FIG. 7 shows this state.
That is, while the play button 5 is pressed, the slide plate 3 continues to move in the direction of arrow B, so even if the fast-forward button 6 is pressed, the pin 6a of the fast-forward button 6 does not move as shown in FIG. As shown in FIG.
This is a so-called queue operation. At this time, when the fast forward button 6 is released, the fast forward button 6 is moved by the coil spring 26.
It will return to normal play state again.

Next, when it is desired to perform a fast-forward song interval detection operation, it is preferable to press the fast forward button 6 and the song interval detection button 7 at the same time while the play button 5 is being pressed as shown in FIG. FIG. 10 shows this state. That is, when the song interval detection button 7 is pressed while the play button 5 is pressed as shown in FIG. 6, the pin 7a of the song interval detection button 7 moves along the protrusion 15 of the slide plate 2. Finally, it is engaged with the hook portion 15a of the protruding portion 15 by the action of the tension spring 21 provided between the one end 2c of the slide plate 2 and the angle portion of the frame (not shown), but this pin 7a protrudes. When moving along the section 15, the slide plate 2 is slid in the direction of arrow A. At this time, by the action of the tension spring 23 provided between the pin 2a of the slide plate 2 and the pin 1a of the slide plate 1, the slide plate 1 is also slid together with the slide plate 2 in the direction of arrow A. FIG. 9 shows this state.
Further, when the fast forward button 6 is pressed while the play button 5 and the song interval detection button 7 in FIG. Finally, a tension spring 23 provided between the pin 1a of the slide plate 1 and the pin 2a of the slide plate 2 is attached to the hook portion 12a of the protrusion 12.
It is engaged by the action of. In addition, fast forward button 6
When the pin 6a moves along the protrusion 12 of the slide plate 1, the slide plate 1 is slid in the direction of arrow B, but at this time the slide plate 2 engages with the song interval detection button 7. Therefore, it does not move in the direction of arrow B. The one that shows this state is the first one.
0, a song interval detection mechanism linked to this time song interval detection button 7 is activated to perform song interval detection in the fast forward state. In addition, a plunger (not shown) having a suction force in the direction of arrow A is provided, and when a song interval is detected, the plunger is activated to pull the slide plate 2 in the direction A, thereby causing the slide plate 2 to slide. (At this time, the slide plate 1 is engaged with the fast forward button 6, so it cannot slide in the direction of arrow A.) By releasing the engagement, the song interval detection button 7 can be returned to its original position by the action of the coil spring 27. When the engagement between the slide plate 2 and the song interval detection button 7 is released, the slide plate 2 moves in the direction of arrow B by the action of a tension spring 21 provided between one end 2c of the slide plate 2 and the angle portion of the frame (not shown). , and returns to the original position (the position where one end 2c of the slide plate 2 hits the angle part of the frame (not shown)), but at that time, the slide plate 1 also touches the pin 2b provided on the slide plate 2.

By pressing c, the slide plate 1 slides in the direction of arrow B, the engagement between the slide plate 1 and the fast-forward button 6 is released, and the fast-forward button 6 is returned by the action of the coil spring 26, and at the same time, the slide plate 1 returns to its original position. do.
At this time, since the slide plate 3 remains engaged with the play button 5, the play state is automatically entered. Next, when the rewind button 8 is pressed while the play button 5 in FIG. 6 is pressed, a review operation is obtained. FIG. 8 shows this state. That is, while the play button 5 is pressed, the slide plate 3 continues to move in the direction of arrow B, so even if the rewind button 8 is pressed, the pin 8a of the rewind button 8 does not move as shown in FIG. As shown, the hook portion 19 of the protrusion 19 of the slide plate 3
a, the tape is rewound and the signal sound recorded on the tape can be heard at the same time, a so-called review operation. At this time, when the pressure on the rewind button 8 is released, the rewind button 8 returns to its original state due to the action of the coil spring 28, and returns to the normal play state.

When it is desired to perform a rewinding song interval detection operation, it is preferable to press the rewind button 8 and the song interval detection button 7 at the same time while the play button 5 is being pressed as shown in FIG. FIG. 11 shows this state. That is, when the song interval detection button 7 is pressed while the play button 5 is being pressed as shown in FIG. It moves along the protrusion 15 of the slide plate 2 and finally touches the hook part 15a of the protrusion 15.
The pin 7a moves along the protrusion 15, and is engaged by the tension spring 21 provided between the one end 2c of the slide plate 2 and the angle portion of the frame (not shown). At this time, the slide plate 2 is slid in the direction of arrow A.
At that time, pin 2a of slide plate 2 and slide plate 1

When the slide plate 1 moves along the protrusion 13 of the slide plate 1, the slide plate 1 is slid in the direction of arrow B, but at this time the slide plate 2 is engaged with the song interval detection button 7. Therefore, it does not move in the direction of arrow B. This state is shown in FIG. 11. At this time, the song interval detection mechanism linked to the song interval detection button 7 is operated to perform song interval detection in the rewinding state. Also, in the same way as the fast forward song interval detection operation, when a song interval is detected, the slide plate 2 is slid by acting on a plunger (not shown) and pulling the slide plate 2 in the direction of arrow A. , since the slide plate 1 is engaged with the rewind button 8, it cannot slide in the direction of arrow A), the pin 7a of the song interval detection button 7 and the hook portion 1 of the protrusion 15 of the slide plate 2
5a is disengaged, and the song interval detection button 7 can be returned to its original position by the action of the coil spring 27. When the engagement between the slide plate 2 and the song interval detection button 7 is released, the slide plate 2 moves in the direction of arrow B by the action of a tension spring 21 provided between one end 2c of the slide plate 2 and the angle portion of the frame (not shown). Move to
The slide plate 1 returns to its original position (the position where one end 2c of the slide plate 2 hits the angle part of the frame (not shown)), but at that time, the slide plate 1 also touches the slide plate 2.
By pushing the side part 1c of the notch 1b provided in the slide plate 1, the pin 2a provided in the arrow B
direction, the engagement between the slide plate 1 and the rewind button 8 is released, and at the same time the rewind button 8 is returned by the action of the coil spring 28, the slide plate 1 is returned to its original position. At this time, since the slide plate 3 remains engaged with the play button 5, the play state is automatically entered.

From the state shown in Figure 5, press the fast forward button 6 or rewind button 8.
Press to get normal fast forward or rewind status,
By pressing the play button 5 and the record button 9 at the same time, a recording state is obtained.

In order to eliminate the state in which each push button is pressed, it is preferable to press the stop button 4.

In this way, the present invention stacks three slide plates 1, 2, and 3 each having an appropriate number of protrusions with hook portions, and provides an appropriate number of push buttons with pins corresponding to these slide plates. In a tape recorder that can detect between songs, it is especially designed to perform queue and review operations.
By pressing the fast forward button 6 and the song interval detection button 7,
The rewinding song detection operation is performed using play button 5 and rewind button 8.
and a song interval detection button 7, a queue operation can be obtained by pressing a play button 5 and a fast forward button 6, and a review operation can be obtained by pressing a play button 5 and a rewind button 8.
