Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a manual operating device that uses mechanical means to reduce operating force.

For example, in the case of conventional intelligent manual operating devices used in tape recorders, etc., a predetermined key is pressed and the operating force is transmitted to an operating member provided corresponding to each key to operate the operating member. The device was configured to perform operations such as playback, recording, fast forwarding, rewinding, and stopping.

However, since the mechanism for performing various functions of the tape recorder acts as a load on each operating member, the conventional device requires a heavy pressing force and has poor operability. Therefore, an electromagnetic plunger is being considered as a device that can be operated with less force.

This operates the plunger by operating a switch and transmits the operating force of the plunger to each operating member.
This invention had drawbacks such as requiring a large-capacity plunger and an expensive transformer.The present invention was made based on these circumstances, and its purpose is to reduce the operating force by mechanical means. An object of the present invention is to provide an inexpensive manual operation device that can achieve the following.

On one surface of the large gear 17, a spiral cam part 20 is provided at the center and an annular protrusion 21 is provided on the periphery. A protrusion 22 and a substantially V-shaped starting protrusion 23 are formed on the outer periphery of the protrusion 22, respectively. In the figure, reference numeral 24 denotes a fixing plate, which is fixed in parallel to the tape recorder board, and the large gear 17 is positioned between the fixing plate 24 and the tape recorder board. The intermediate portion of the locking member 13 and one end portion of the cam lever 25 are attached to the fixing plate 24, respectively.

has a locking claw 28 bent at one end, and the fixing pin 2
Su that was passed between 9! The spring 30 is constantly biased in the counterclockwise direction in FIG.
The annular protrusion 21 is elastically brought into contact with the inner circumferential surface of the annular protrusion 21. On the other hand, a leaf switch 31 is attached to the tape recorder board. This switch 31 has 1 point and 3 points of first and second switching contacts.
A movable contact 31c made of a leaf spring is arranged between 1a and 31b,
A pressing piece 31d is attached to the tip of the first switching contact 31a, and the pressing piece 31d and the movable contact 31c are connected by a toggle spring 31e made of a leaf spring. In the case, the pressing piece 31d is brought into elastic contact with the side surface of the starting protrusion 23, and the large gear 1 is
7 in the direction of arrow 32 (counterclockwise),
The movable contact 31c is in contact with the first switching contact 31a, or the large gear 17 is moved in the direction of the arrow 32. The movable contact 31c comes into contact with the second switching contact 31b by operating as the movable contact 31c rotates (see FIGS. 6 and 8). and the second
As shown in the figure, the locking claw 29 of the locking member 13 is connected to the locking protrusion 22.
In a state where the large gear 17 is prohibited from rotating in the direction of the arrow 32, the pressing piece 31d of the switch 31 rides on the starting protrusion 23, and the movable contact 31c contacts the first switching contact 31a. The large gear 17 is urged in the direction of the arrow 32, and the notch 18 faces the pinion 16 to operatively separate the large gear 17 from the pinion 16. A cam roller 33 is attached to the middle portion of the cam lever 25.

The rotating end of the lever 25 and the connecting arm 6c of the transmission member 6 are connected via a spring 34, and a spring 35 is connected between the lever 25 and the fixing pin 29.
The cam roller 33 is brought into elastic contact with the outer periphery of the cam portion 20. FIG. 3 shows a motor drive circuit, in which a power switch 37 is connected in series to the DC power source 36, and a movable contact 31c of the leaf switch 31 is connected to the DC power source 36 in series.
A motor 38 for driving the capstan shaft 15 and a reel shaft (not shown) is connected via the second switching contact 31b in series.

The power switch 37 is closed in conjunction with playback, recording, fast-forwarding, or rewinding operations, and for example, when any of the operating members 3 for playback, recording, fast-forwarding, or rewinding moves forward. The closed state is maintained while the actuating member 3 is locked in the forward movement position by the locking plate 5. Next, the operation of this embodiment will be explained.

First, FIGS. 1 to 3 show the state before operation, in which the tape recorder is stopped.

Therefore, one of the buttons for playback, recording, fast forward, rewind, etc.
When one or two buttons are selected and pressed, the intervening body 7 located below is pushed down from above as indicated by arrow 9. When the locking piece 7e is lowered, the locking piece 7e slides into contact with the locking edge 10d of the release member 10 to rotate the release member 10 as shown in FIG. Push it against the spring 30 as shown by the arrow 14 in the drawings and FIG. 5 to disengage the locking pawl 28 of the locking member 13 from the locking protrusion 22 as shown in FIG. Then, the large gear 17 is pushed by the pressing piece 31d of the switch 31 and rotates slightly in the direction of the arrow 32 as shown in FIG.
The notch 18 moves in the same direction to engage the large gear 17 and pinion 16, and at the same time, the movable contact 31c of the switch 31 contacts the second switching contact 31b. This starts the motor 38 and rotates the carburetor shaft 15 and the reel shaft. When the large gear 17 meshes with the pinion 16 and the carbstan shaft 15 rotates, the large gear 17 is rotationally driven in the direction of arrow J 32 as shown in FIG. Cam roller 33
, and move the cam lever 25 against the spring 35 to the seventh position.
Move it counterclockwise as shown by arrow 36 to the position shown in the figure.
This forward movement of the cam lever 25 is transmitted to the transmission member 6 via the spring 34, and the transmission member 6 is
Rotate in the direction. At this time, the transmitting part 6 presses the contact part 7d of the insert 7 with the pressing part 6b, and pushes the insert 7 and the actuating member 3 together in the direction of arrow 38 in FIG. 8. The actuating member 3 is then locked in its forward movement position by the locking plate 5, and the tape recorder starts a predetermined operation. At this time, the power switch 37 closes as the push button is pressed.
Since the closed state is maintained while the actuating member 3 is locked to the locking plate 5, even if the movable contact 31c of the leaf switch 31 switches to the first switching contact 31a side during that time, the motor 3 remains closed.
8 does not stop. Furthermore, even if the transmission section 6 rotates in the direction of the arrow 37, the contacting section 7d of the insert 7 that has not been pushed down is not pushed by the pressing section 6b, and therefore the pushing section 7d is not pushed down. Only the intervening body 7 and the corresponding actuating member 3 are pushed by the transmission member 6 and rotated. On the other hand, the locking member 13 is pushed around by the pressing piece 1c of the release member 10 and eventually separates from the inner peripheral surface of the annular protrusion 21, but the large gear 17 rotates in the direction of arrow 32 and the locking member 13 The portion 22 is the locking claw 2
8, as shown in FIG. 8, the pressure by the pressing piece 10c is released and the spring 30 returns to the annular protrusion 2.
It comes into contact with the inner peripheral surface of 1.

Therefore, when the large gear 17 rotates once more and the notch 18 comes to face the pinion 16, the locking pawl 28 is hooked on the locking protrusion 22, and the large gear 17 is again operatively removed from the pinion 16. It is locked in the disengaged position. At this time, the pressing piece 31d of the switch 31 comes into elastic contact with the starting protrusion 23 again as shown in FIG. It can be rotated to a position where it engages with the When the large gear 17 rotates once, the cam roller 33 drops from the maximum radius to the minimum radius of the cam portion 20, and the cam lever 25 returns to its initial position, changing from the state shown in FIG. 7 to that shown in FIG.

At this time, the transmission member 6 also returns to the initial position together with the cam lever 25 as shown in FIG. 9, but the actuating member 3 is still held in the forward movement position by the locking plate 5. Also, the release section. Material 1
When the intervening body 7, which was held in the lowered position by the actuator 0, rotates together with the actuating member 3, it releases the locking pawl 7e from the locking edge 10d of the opening of the release member 1, and the While maintaining the rotational change position (tilt), the spring 8 returns to the upward position, resulting in the state shown in FIG. In other words, FIG. 9 shows a state in which a specific operating member 3 is locked in the forward movement position by the locking plate 5, and operations such as playback, recording, fast forwarding, or rewinding are performed. To cancel the state, just press the stop button. That is, when the stop push button is pressed in the ζ state shown in FIG. The actuating member 3 which is locked by the actuating member 3 is released, and the actuating member 3 returns to its original state without being locked by the locking plate 5. For example, during a playback operation, if you want to switch to another operation, such as a rewind operation, you can press the desired (rewind) button.

That is, when another intervening body 7 descends in the state shown in FIG. 9, the above operation is performed, and the actuating member 3 corresponding to the push button pressed later moves forward to replace the previous (regenerating) actuating member. It is locked by the locking plate 5 and switched to the desired (rewinding) operation. Furthermore, if the push button that causes the same operation to be pressed again is accidentally pressed while performing a specific operation, that is, in the state shown in FIG. The locking claw 7e locks the locking edge 10d of the release member 10, so the release/removal member 10 does not rotate.
Does not cause malfunction.

Note that operations such as recording, fast-forwarding (cue), rewinding (review), etc. are normally performed by pressing two buttons at the same time, but even with this manual operation/device, pressing two buttons at the same time will perform these operations. The two corresponding actuating members are locked in the forward movement position by the locking plate, allowing the desired operation to be performed.

According to the manual operating device configured as described above, the force for operating the actuating member 3 is given by the pinion 16 as the main rotating body, that is, the capstan shaft 15, and when manually operated, the force is simply transmitted between the intervening body 7 and the actuating member 3. Since it is only interposed between the actuating member 6 and the actuating member 6, the operating force can be significantly reduced compared to the conventional device in which the actuating member is directly actuated by manual operation.

Further, since the pinion 16 as the main rotating body is fixed to the capstan shaft 15, a drive source dedicated to the manual operating device is not required, and the structure can be simplified and the manufacturing cost can be reduced. In addition, since the intervening body 7 is selectively interposed between the transmission member 6 and the actuating member 3 to interlock both members 6 and 3, only the actuating member 3 corresponding to the manually operated intervening body 7 can be interlocked with the transmission member 6, one transmission member 6 can be shared by all the operating members 3, and no malfunction will occur due to the transmission member 6 being shared. Furthermore, the intervening body 7 is locked in the lowered position by the release member 10, and the lock is released by rotation of the actuating member 3, so the user does not have to keep pressing the push button until the actuating member 3 is activated. However, the problem that the intervening body 7 returns midway does not occur. In addition, since the intermediate body 7 that has been pushed down is held at the rotating position until the actuating member 3 returns to the initial position, by detecting the rotating intermediate body, mechanical or electrical It is possible to display what kind of operation is currently being performed through the means. This manual operation device can use the operating members, locking members, etc. of conventionally well-known tape recorders as is, and can utilize the rotational force of the capstan shaft, so there is no need to make any major design changes to existing tape recorders. It can be applied relatively easily. Note that the present invention is not limited to the above-mentioned embodiments, and can be implemented with various modifications.

For example, in the embodiment described above, the intervening body 7 is attached to each actuating member 3, but it may be attached to a common transmission member 6, or it may be attached to a completely different member. Further, in the above embodiment, the lowering of the intervening body 7 rotates the releasing member 10 to release the locking state of the locking member 13 with respect to the large gear 17. The locked state may be released by rotating in the opposite direction. Furthermore, although a part of the release member 10 (the locking edge 10d) is used as the intervening body locking portion, the intervening body locking portion may be provided in a part other than the release member. Further, the main and slave rotating bodies may be gears and a series of pulleys, for example, and may be configured to be interlocked via an endless belt. It is also possible to engage and disengage the two rotating bodies by changing the distance between the axes. Further, the intervening body does not need to be positioned between the transmission member and the actuating member, and it is sufficient if it is operatively interposed between the two members J. Further, in the embodiment, the movable contact 31c of the leaf switch 31 and the elasticity of the toggle spring 31e bias the large gear 17 in the direction of meshing with the pinion 16, but it is possible to perform this action with a member other than the switch. You can also do this. Further, in the embodiment, the intervening body is pressed down via a push button, but the intervening body may be manually operated directly. Of course, the present invention can also be applied to devices other than tape recorders.

As described above, according to the manual operating device of the present invention, the force for operating the actuating member is applied by the main rotating body, and in the manual operation, an intervening body is interposed between the actuating member and the transmission member, and Since the locking member is simply removed from the slave rotor through the release member, the operating force can be significantly reduced, and
Since it can be easily constructed by mechanical means, excellent effects such as lower manufacturing costs can be achieved compared to conventional devices using plungers.
