Description

[Detailed Description of the Invention] The present invention provides inexpensive buttons that allow basic functions of a recording/playback device to be performed by operating them with a small number of operation buttons, and that also allow the user to know the content of the function being operated. It relates to an operating device.

In detail, you can use the play button, back button, and fast forward button to move back or fast forward without locking during play, and when you release your hand, it immediately returns to the playing state, and when backing or fast forwarding is done with lock. This relates to an operation button device for a recorder/player that automatically releases back or fast forward when the play button is locked, and at the same time each button is not locked to prevent erroneous operation. The purpose is to ensure that each operation necessary for recording and playback can be performed quickly with a small number of buttons.

Nine buttons with the following functions are known as operation buttons for recording and playback equipment.

(1) A play button (also commonly referred to as a feed button or a play button) that has the function of playing a sound by running a recording medium at a constant speed.

(2) A fast-forward button (commonly referred to as an FF button or a winding button) that has a function of winding the recording medium at a higher speed than during playback.

(3) A rewind button (commonly known as Back
button or rewind button).

(4) A stop button with a function to stop the play state, fast forward state or winding state.

(5) A recording button (also commonly referred to as a REC button) that has the function of recording on a recording medium that runs at a constant speed.

(6) A review button (also commonly referred to as a repeat button or space button) that, when pressed while the play button is pressed, rewinds the recording medium only while the button is pressed.

(7) Cue button (also known as cue button).

(8) An eject button with a function that facilitates ejecting the cassette containing the recording medium.

(9) A pause button with a function to pause the recording medium during recording or playback.

etc.

Generally, devices are equipped with nine buttons that have the above-mentioned functions, but depending on the specifications, they may also be equipped with various buttons that have other additional functions. There are devices that have fewer buttons than the above-mentioned general devices, such as dictation recorders.

Among these devices, general cassette tape recorders have a stop button (in case (4) above), an eject button (in case (8) above), a fast forward button (in case (2) above), and a cue button (in case (2) above). In the case of (7) above), and the rewind button (
In the case of (3) above) and the review button (in the case of (6) above)
These buttons, the play button above (in the case of (1) above), and the record button (in the case of (5) above)
(in the case of (9) above) and a pause button (in the case of (9) above), with a total of 6 buttons arranged in a row, and 5 of these, excluding only the pause button above, without the pause function. Usually, the buttons are arranged in a row.

However, in the case of such a recording/playback device, there are the following problems in operating each button when performing each function operation.

First, since several similar operation buttons are lined up in the same way, you must be careful when selecting and pressing the desired button, especially when pressing the stop button ((4) above). When trying to press a button (if applicable), it is often difficult to choose which button corresponds to the button.

Second, in the button operation mechanism of relatively low-cost equipment,
If two or more operation buttons are accidentally pushed in at the same time, these two buttons may become locked together, and even if they are not locked, the tape running function will work when pushed in.

In particular, there is a risk that the tape may break during fast forwarding (also known as FF, case (2) above) and rewinding (also known as back, case (3)).

By the way, if we distinguish between the above-mentioned operation buttons that have a basic function as a recording/playback device and those that do not,
Since the basic functions of a recording/playback device are satisfied if it can record and playback, the play button and record button are the two most basic operation buttons.

In this case, when recording, the play button and the record button are both operated, and when playing, only the play button is operated.

In this sense, these two buttons can be called basic operation buttons.

Next, in the sense that it would be convenient to have fast-forward and rewind functions in addition to the above-mentioned recording and playback function, the fast-forward and rewind buttons can be said to be secondary operation buttons next to the basic operation buttons described above. .

Furthermore, the stop button is a button for canceling or canceling the maintenance function of the basic operation button and secondary operation button, and is a so-called emergency button.
In the sense of a science button, it can be said to be a tertiary operation button following the above-mentioned secondary operation button.

In this way, various operation buttons can be ranked according to their functions and properties.

Therefore, the present invention eliminates the drawbacks of the conventional method by making it possible to perform each operation necessary for recording and playback reliably and quickly using only the three play buttons, back button, and fast forward button that can be pressed on and off independently. Next, one embodiment shown in the accompanying drawings will be described in detail.

In FIG. 1, reference numeral 1 denotes a housing, and the upper end of a reset plate 3 is pivotally attached to an upper horizontal shaft 2, and a helical spring 4 is attached to the upper horizontal shaft 2.
It is pressed so that it always rotates.

At the bottom, a play button 5, a back button 6, and a fast forward button 1, which can be slid back and forth with respect to the page, are arranged.

Each button is constantly pressed to the left by springs 9, 10, and 11 attached to a shaft at the bottom of the housing 1 (FIG. 4).

A pin 12, 13, 14 is provided protruding from the top of each button, and a shift lever (Figs. 2 and 4) 15, 16, 17 is pivotally mounted so as to be able to rotate around the pin 12. .

In FIG. 1, a shaft 18 provided at the center front of the housing 1 has three buttons corresponding to a play button 5, a back button 6, and a fast forward button 7.
The engagement levers 19, 20, 21 are pivotally connected, and the shaft 18 (
(Fig. 4), and one end 19', 20' in Fig. 4.

21' are engagement protrusions 22 and 23 of the reset plate 3.
．． 24, and the other ends 19'', 20'', 21'' are adapted to abut on one end of the shift levers 15, 16, 17 (FIG. 2).

In FIG. 2, reference numerals 25, 26, and 27 indicate plates attached to the housing 1 so as to press the left side of the shift levers 15, 16, and 17 of each button.

The rear part of the bottom surface of each button (Fig. 2), that is, the right part of the bottom surface (the fourth
In the figure), projections 28, 29, and 30 are provided.

A top hole 32 of a triangular interlock plate 31 (FIGS. 5 and 4) is fitted and pivoted on the bottom surface of the housing 1 so that it can swing around this hole. .

An engaging protrusion 34 is formed on the right side of the upper surface of the interlock plate 31 (FIG. 5) parallel to its bottom edge 33, and a groove 35 into which the right protrusion 28 on the lower surface of the play button is inserted is formed in the center of the engaging protrusion 34. It is formed.

Next, the operating state will be explained.

When the play button 5, back button 6, and fast forward button 7 are in the inactive position, shift levers 15, 16, 17 are moved as shown in FIG.
Since the pins 12, 13, and 14 are located in front of the leaf springs 25, 26, and 27, each shift lever 15, 16, and 17 receives a force that rotates clockwise as shown by arrow A in FIG. , the engagement recesses 36, 37, 38 formed on the left front side of the shift levers 15, 16, 17 are engaged with the engagement levers 19, 37, 38, respectively.
The front ends of 20 and 21 (FIG. 4) are engaged with 19'', 20'' and 21''.

At this time, the rear ends 19', 2 of the engagement levers 19, 20.
0', 21' are engagement protrusions 22 of the reset plate 3,
It is in contact with the lower parts of 23 and 24.

(Fig. 4) In Fig. 10, when the play button 5 is pressed now, the projection 28 of the button 5 slides to the right through the groove 35 of the interlock 31 against the elasticity of the spring 9, and at the same time the shift lever 15 is pressed. The front end 19'' of the engagement lever 19 engaged with the engagement step 36 (FIG. 2) is rotated counterclockwise in FIG. 3 is pressed, and the reset plate 3 is pressed and rotated counterclockwise around the pin 2 against the elasticity of the helical spring 4.

When the pin 12 of the shift lever 15 passes through the point of action of the leaf spring 25, the shift lever 15 receives a force to rotate counterclockwise as shown by arrow B as shown in FIG.
6 and the contact surface of the retaining step 36 of the front end 19'' of the engagement lever 19 is designed to be larger, so the engagement lever 19 is integrated with the shift lever 15. There is.

The rear end 19' of the engagement lever 19 is engaged with the corner of the engagement protrusion 22 of the reset plate 3, as shown in FIG.

When you release your hand, the play button 5 is pushed back by the spring 9, and the shift lever 15 is also pulled forward to engage the engagement step 36.
The frictional force between the contact surface of the front end 19'' of the engagement lever 19 becomes smaller, and the engagement step 36 becomes closer to the front end 19'' of the engagement lever 19.
9'' (FIG. 8), the other engagement step 36' engages with the front end 19'' of the engagement lever 19 and stops.

Next, when the locked play button 5 of FIG. 8 is pressed, the button 5 slides further to the right (FIGS. 10 and 11) against the elasticity of the spring 9, and the right end of the shift lever 15 is moved. Since the lower end of the reset plate 3 is pressed and rotated in the direction of arrow C, the engagement protrusion 22 is disengaged from the rear end 19' of the engagement lever 19 (FIG. 11), so that the engagement lever 19 is rotated clockwise.

When the user releases the hand, the play button 5 returns to its original position due to the elasticity of the spring 9 as shown in FIG.
engage with.

Next, when the play button 5 is locked, the protrusion 28 is fitted into the groove 35 of the interlock plate 31, so when the back button 6 or the fast forward button 7 is pressed at this time, the play button (not shown) is pressed. Even if the protrusions corresponding to the protrusions 28 contact the engaging protrusions 34 (FIG. 5) of the interlock plate 31, the interlock plate 31 cannot be rotated left or right, so it will not be locked and will not lock while being pressed. Only backward or fast-forward motions are performed, and when you release your hand, you immediately return to the playing state.

Next, when the play button 5 is not locked, when the back button 6 or the fast forward button 7 is pressed, the corresponding protrusion 2 (not shown) is pressed.
9 or 30 is the engagement protrusion 3 of the interlock plate 31
4 is pressed to swing the interlock plate 31 left and right, so it is locked in exactly the same way as the play button 5.

Then, when you release the button again, the lock is released and the button returns to its original position, just like when pressing play button 5.

Next, when the back button 6 or fast forward button 7 is locked,
When the play button 5 is pressed, the rear end 1 of the play button engagement lever 19
9' is longer than the rear end of any of the other engagement levers (not shown), so the rear end 19' pushes the lower end of the reset plate 3 in the direction C in Figure 4. The rear end of the engagement lever has an engagement protrusion 23, 24 (
11) and returns to the original position, the play button 5 is locked as described above, and play is immediately started.

According to the present invention, there is no need for a lock release button, and the play button, back button, and fast forward button can be turned on and off independently, allowing play, back, and fast forward operations to be performed independently. can be performed in a locked state, and even if the back button or fast forward button is pressed during the play operation, it will not lock, and the back or fast forward action will only be performed while the button is pressed, and if you release your hand, it will immediately return to the play state. be able to.

In this case, cue and review functions can be added using these fast-forward and back buttons, and in this way, the cue and review functions can be conveniently performed using three buttons.

Furthermore, if you lock the play button while the back button or fast forward button is locked, the back button or fast forward button will be automatically unlocked and you can immediately enter the play state, so there will be no erroneous operation and the operation will be reliably quick. Moreover, only three push-on/button-off buttons are required, and each shift lever is provided on each thin piece of soil, and these operations can be performed only by plane movement, making the device simple and inexpensive. This effect is even greater when each part is made by plastic molding.

It should be noted that the gist of the present invention will not be changed in any way even if any mechanism is used for each part as long as it has a mechanism that allows push-on and push-off.

Further, when recording and reproducing sound, the recording and reproducing apparatus according to the present invention may use any method such as magnetic, optical, or mechanical, and furthermore, it can use tapes, sheets, cards, disks, etc. as the recording and reproducing medium. This also includes cheating educational devices.
