Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an operating device for a tape recorder that can set the tape drive mechanism to a desired operating mode, such as playback or fast forward, by soft touch operation.

Conventionally, the suction force of a plunger has been used to set the tape drive mechanism to a desired operating mode by soft touch operation, but since the tape drive mechanism is instantaneously switched when driven by such a plunger, There is a risk of applying a strong impact force to various parts of the drive mechanism, significantly reducing its mechanical life, and since the plunger and its connection mechanism are separately provided, assembly is time-consuming and space-consuming. Ta. Therefore, recently, tape recorders have appeared that make good use of the rotational force of the motor to switch the tape drive mechanism to a desired operating mode during soft touch operations, such as those shown in Figures 1 to 5. It's structured well. That is, in the figure, 1a to 1f are recording and rewinding devices which are slidably disposed through through holes (not shown) in the front and rear bent portions 3a and 3b of the mounting bracket 3 attached to the chassis 2, respectively. , a plurality of non-locking operating levers for playback, fast-forwarding, stopping, and pausing, etc., each of which is triggered in the direction of arrow A against a return spring (not shown). Reference numeral 4 denotes a trigger operation slide that is slidably provided in the left and right bent portions 3c and 3d of the mounting bracket 3 through through holes (not shown), and is always biased in the direction of arrow B by a spring (not shown). The trigger operation slide 4 has contact pieces 1 for each of the operation rods 1a to 1f.
Inclined portions 4a to 4f are provided at positions corresponding to a' to 1f', so that when any one of the operating rods 1a to 1f is triggered in the direction of arrow A, these contact pieces 1a' 〜1f′ corresponds to the inclined portion 4
The trigger operation lever 4 is made to slide in the opposite direction of arrow B by coming into contact with one of a to 4f.

Reference numeral 5 designates a trigger lever having a locking portion 5a at one end, and whose central portion is rotatably supported by a shaft 6 on the chassis 2, and the other end is fitted into the fitting hole 4g of the trigger operation slide 4. Therefore, when the trigger operation slide 4 slides in the direction opposite to arrow B, it is rotated counterclockwise. Reference numeral 7 denotes a flywheel which has a capstan 9 projecting from the upper surface of the chassis 2 via a capstan bearing 8 and is rotationally driven in a counterclockwise direction by a motor (not shown).
0 is provided integrally. Reference numeral 11 denotes a partially toothed gear 11 that has a partially toothed portion 11a and is rotatably supported 12 on the rear surface of the chassis 2 to mesh with the drive gear 10. is integrally provided, and when its toothless portion 11a faces the drive gear 10, it engages with the locking portion 5a of the trigger lever 5 to prevent clockwise rotation of the toothless gear 11. Protrusion 1
4 is provided. 15 is the long hole 16, 16
and the planting pins 17, 17 so as to be slidably provided on the rear surface of the chassis 2, and the protruding portion 1
A control slide 5' is biased in the opposite direction of arrow B by a spring 18 so as to be in constant contact with the eccentric cam 13 of the partially toothed gear 11, and the control slide 15 is energized when the partially toothed gear 11 rotates clockwise. When the partially toothed gear 11 is slid in the direction of arrow B through the contact relationship between the eccentric cam 13 and the protruding portion 15', and the partially toothed gear 11 is prevented from rotating clockwise by the trigger lever 5, the first As shown in the figure, the protruding portion 15' comes into contact with the eccentric cam 13 of the partially toothed gear 11 at a point outside the shortest diameter part, and imparts a clockwise rotational force to the partially toothed gear 11. .

Therefore, any one of the operating rods 1a to 1f is triggered in the direction of arrow A, and the trigger operating slide 4 slides in the opposite direction of arrow B, so that the toothless gear is engaged by the locking portion 5a of the trigger lever 5. When the engagement with the protrusion 14 of 11 is released, the partially toothed gear 1
1 is the protruding portion 1 of the eccentric cam 13 and the control slide 15
5', the control slide 15 is immediately rotated clockwise to mesh with the drive gear 10, and the eccentric cam 13 slides the control slide 15 in the opposite direction of arrow B while driving the control slide 15 clockwise. be done. and the partially toothed gear 11
After one rotation, the trigger lever 5 prevents the rotation with the toothless portion 11a facing the drive gear 10 again, and during that time the control slide 15 is rotated once.
Move back and forth only once. 19a to 19f are pressure pieces 1a'' to 1 of each operating rod 1a to 1f as shown in FIG.
axes 20a to 2 on the back of chassis 2, respectively
A mode switching lever is rotatably provided at 0f and slidable in the axial direction, and one end of the mode switching lever 19a to 19f is provided with the control slide 1.
A plurality of fitting pins 19a' to 19f' are provided to fit into the fitting holes 15a to 15f of No. 5, respectively.
As shown in the figure, each of the fitting pins 19a' to 19f' is connected to the fitting hole 15a to 15a by a plurality of springs 21a to 21f wound around each of the shafts 20a to 2f.
It is always energized in the direction of departure from 15f (counter-arrow A direction). and the mode switching lever 19
At the other ends of a, 19b, 19c, 19d, and 19f, there are operating levers for recording, rewinding, and playback, which are slidably provided on the back of the chassis 2 and are each energized in the direction of arrow C by a spring (not shown). 22a~
Operation pins 19a'' and 19 in contact with 22e, respectively.
b″, 19c″, 19d″, and 19f″ are provided.
Therefore, each of the operating levers 22a to 22e corresponds to each mode switching lever 19a, 19b, 19c, 19.
By rotating counterclockwise d and 19f, they are respectively caused to slide in the counter-arrow C direction, setting the tape drive mechanism section to a predetermined operation mode. Reference numeral 23 denotes a lock slide which is slidably provided on the rear surface of the chassis 2 through elongated holes 24, 24 and implant pins 25, 25, and which is always biased in the direction of arrow B by a spring 26. are lock portions 23a to 23a for locking the lock pieces 22a' to 22d' of each of the operating levers 22a to 22d to lock the operating levers 22a to 22d in the operating state;
23d, and has a release piece 23e that comes into contact with an operating pin 19e'' provided at the other end of the mode switching lever 19e for stopping.

Therefore, the lock slide 23 is slid in the opposite direction of arrow B through the abutting relationship between the operating pin 19e'' and the release piece 23e when the stop mode switching lever 19e is rotated counterclockwise. , each of the operating levers 22 by its locking portions 23a to 23d.
Unlock locks a to 22d. Note that each of the mode switching levers 19a to 19f is rotated clockwise by a spring (not shown), and as shown in FIG.
The stopper pieces 1a to 1f are in contact with each other. Further, 27 is a cassette, and 28 and 29 are a supply reel stand and a take-up reel stand provided on the chassis 2.

It is configured as described above, and its operation will be explained below.

First, in the stopped state, each of the operating rods 1a to 1f is in a non-operating position as shown in FIGS. Slide 4 is also in the non-sliding position. Therefore, the trigger lever 5 locks the partially toothed gear 11 with its partially toothed portion 11a facing the drive gear 10, as shown in FIG. 1, and prevents its rotation. The mode switching levers 19a and 19f facing the pieces 1a'' to 1f'', respectively, are also in a state where their fitting pins 19a' to 19f' are separated from the fitting holes 15a to 15f of the control slide 15, respectively, by the respective springs 21a to 21f. . Therefore, each of the operating levers 22a to 22d is not operated, and the tape drive mechanism is in the stop mode.

Next, when the regeneration operating rod 1c is triggered in the direction of arrow A against the biasing force of a spring (not shown) from such a stopped state, the contact piece 1
The trigger operation slide 4 is slid in the direction opposite to the arrow B through the contact relationship between c' and the inclined portion 4c, and the trigger lever 5 is also rotated counterclockwise accordingly. The mode switching lever 19c corresponding to 1c is also slid by its pressing piece 1c'' in the opposite direction of arrow C against the urging force of the spring 21c, and its fitting pin 19c' is inserted into the fitting hole 15c of the corresponding control slide 15. Therefore, since the locking portion 5a of the trigger lever 5 is disengaged from the protrusion 14 of the partially toothed gear 11, the partially toothed gear 11 is inserted into the eccentric cam 13 and the protrusion of the control slide 15 Spring 1 via installation part 15'
The control slide 15 is immediately rotated clockwise by the applying force of 8 to mesh with the drive gear 10, and is rotated clockwise by the drive gear 10 so that the eccentric cam 13 causes the control slide 15 to slide in the direction of arrow B. Driven. Therefore, the control slide 15 is made to slide in the direction of the arrow B against the biasing force of the spring 18, and therefore, the control slide 15 has a fitting pin 19c' fitted into the fitting hole 15c. The mode switching lever 19c is rotated counterclockwise, and the operation pin 19c'' is used to slide the regeneration operation lever 22c in the direction opposite to the arrow C.The regeneration operation lever 22c is The engagement between the lock piece 22c' and the lock portion 23c of the lock slide 23 locks the tape drive mechanism into a predetermined playback mode.

Then, when the toothless gear 11 rotates once and its toothless portion 11a faces the drive gear 10 again, the trigger operation slide 4 is already in its original rotation blocking position as the non-locking operating rod 1c returns.
The trigger lever 5, which has returned to its original state via the trigger lever 5, prevents its rotation and enters a state in which it waits for clockwise rotation by the spring 18. At this time, the regeneration mode switching lever 19c has returned to its original state in which its insertion pin 19c' has been removed from the insertion hole 15c of the control slide 15, and the control slide 15 also has its insertion holes 15a to 15f as described above. It has returned to its original state corresponding to the insertion pins 19a' to 19f' of each mode switching lever. Therefore, from this reproducing state, other operation modes can be set by operating the other operation levers 1a, 1b, 1c, 1d, 1f, etc.

Incidentally, when the operating rod 1c for regeneration is continued to be pushed in the direction of arrow A, the trigger lever 5 is rotated counterclockwise by the trigger operating slide 4 (that is, the protrusion of the partially toothed gear by the locking portion 5a) However, the stopper portion 5b is brought into the transition passage of the protrusion 14 in place of the locking portion 5a, and the toothless portion 11a of the toothless gear is held in the state in which the engagement with the toothless gear 14 is released.
When the gear 11 faces the drive gear 10, its rotation is immediately blocked, so the partially toothed gear 11 is not repeatedly driven to rotate clockwise (see FIG. 5).

Therefore, the operation lever 1e for stopping from such a reproducing state
When the trigger is operated in the direction of arrow A, similarly, the partially toothed gear 11 can be immediately rotated clockwise via the trigger operation slide 4 and the trigger lever 5 to mesh with the drive gear 10, and the mode for stopping can be switched. Fitting pin 19 of lever 19e
e' can be fitted into the fitting hole 15e of the control slide 15, the mode switching lever 19e can be rotated clockwise via the control slide 15, and the operating pin 19e'' can be locked via the release piece 23e. The slide 23 is slid in the opposite direction of arrow B to release the lock of the reproducing operation lever 22c by the lock portion 23c, and the tape drive mechanism is placed in a predetermined stop mode.

However, in a tape recorder having such a configuration, when performing a timer standby operation for playback or recording, for example, since each operating lever 1a to 1f is a non-locking type, the tape drive mechanism section must be activated for playback or recording before turning off the power. After setting the recording operation mode, it was necessary to perform a pause operation and set the timer standby state, and this operation was troublesome. Further, a special mechanism (for example, using a plunger or the like) is required to release the timer standby state (ie, temporary stop state) when the timer device or the like is powered on.

With this in mind, the present invention provides a separate standby operation lever and a standby locking slide that is controlled by the operation lever so that the timer standby operation can be performed easily. An example thereof will be described with reference to the drawings. Note that parts that are the same as those in the prior art will be given the same drawing numbers and their explanations will be omitted.

That is, like the trigger operation slide 4, 30 is slidably provided at the left and right bent portions 3c, 3d of the mounting bracket 3 through through holes (not shown), and is always kept in the operating position by a spring 31. The standby locking slide 30 is energized in the opposite direction of arrow B, and the standby locking slide 30 is in the operating position when the playback and recording operation rods 1a and 1c are energized.
are engaged with the contact pieces 1a', 1c' of the respective operating rods 1a, 1.
The control slide 1 has hook portions 30a and 30b for locking the control slide 15 in the direction of arrow B.
Therefore, when the control slide 15 moves in the direction of arrow B, the locking slide 30 has a bent portion 30c that comes into contact with the extending portion 15'' of the control slide 15. 15'', the playback and recording operating rod 1 is moved from the operating position to the non-operating position (in the direction of arrow B) by the control slide 15.
The movement is made to release the locking at the trigger operation positions of a and 1c. Further, the locking slide 30 is provided with an inclined portion 30d at a position corresponding to the abutment piece 1e' of the stop operation lever 1e, and when the stop operation lever 1e is operated, the abutment piece 30d 1e' and inclined part 3
It is moved to the non-operating position by contact with 0d. 3
2 is slidably disposed on the front and rear bent portions 3a, 3b of the extending mounting bracket 3 through a through hole (not shown) in the same manner as each of the operating rods 1a to 1f, and is attached to a spring 33. A standby operating lever that is operated in the direction of arrow A against the standby operating lever 32
The protrusion 3 of the locking slide 30 when not operated.
0e to set the locking slide 30 in a non-operating position independent of the operating rods 1a, 1c and the control slide 15, and a protrusion 30e of the locking slide 30 during operation.
The locking slide 30 has an allowance recess 32b into which the locking slide 30 is fitted to allow the locking slide 30 to move to the operating position.

Therefore, for example, when performing a timer standby operation for regeneration operation, the standby locking slide 3 is operated by operating the standby operating rod 32 against the biasing force of the spring 33 while the power is cut off.
0 is set to the operating position (that is, the protrusion 30e of the standby locking slide is fitted into the allowable recess 32b of the standby operating lever), and then the regeneration operating lever 1c is triggered in the direction of arrow A. The operating rod 1c can be put into a playback standby state in which it is locked at the trigger operating position by the hook portion 30b of the locking slide 30 for standby, and then when the power is turned on by a timer device or the like, the control slide is activated as described above. 15 is operated to set the tape drive mechanism section to a predetermined reproduction operation mode, and the operation of the control slide 15 moves the standby locking slide 30 to the non-operating position, and the locking slide 30 sets the tape drive mechanism to a predetermined playback operation mode. Operation rod 1
c and the standby operating rod 32 are unlocked.

Then, the standby operating rod 32 immediately returns to the non-operating position (in the direction of arrow A) due to the biasing force of the spring 33, and brings its blocking portion 32a into contact with the protruding portion 30e of the standby locking slide 30. The standby locking slide 30 is set to a non-operating position completely independent of the playback and recording operation rods 1a, 1c and the control slide 15.

The above has described the timer standby operation for playback operation, but the same applies to the timer standby operation for recording operation. After operating the standby operation lever 32 in the power-off state, both playback and recording operation levers 1a and 1c are operated. You can do the same thing by operating the trigger. Further, the standby state can be canceled by operating the standby operating rod 32 through the abutting relationship between the abutment piece 1e' and the inclined portion 30d by operating the stop operating lever 1e. By moving the locking slide 30 to the inoperative position, the same effect as the release by the control slide 15 can be performed.

As described above, according to the operating device of the tape recorder of the present invention, even if the trigger is operated from any of the plurality of operating rods, a single control that receives the rotational force of the motor and reciprocates only once and stops. A tape recorder in which the operating members corresponding to the respective operation rods are operated by members to lock the operating state thereof, and the tape drive mechanism is set to a desired operating mode such as playback or fast playback. a standby locking member that locks each of the playback and recording operation rods in a trigger operation position at a position, and is moved from an activated position to a non-activated position by the control member when the control member is activated; When the locking member is not operated, the locking member is set to a non-operating position unrelated to each of the operating rods and the control member, but when the locking member is operated, the locking member is moved to the working position and the locking member locks the operating state. A standby operating lever is provided, and when the standby operating lever is operated in a power-off state, the standby operating lever is locked by the locking member, and each of the playback and recording operating levers is locked. are set to a standby state in which they are locked at their respective trigger operation positions, and when the power is turned on from the standby state, the control member is operated to release the locking of the standby operating rod by the locking member and the locking member is turned off. It is configured to be moved to a non-operating position unrelated to the playback and recording operation levers and control members. Therefore, when performing a timer standby operation such as playback or recording, the tape drive mechanism section is set to the playback or recording operation mode in advance before the power is shut off, and then a pause operation is performed to set the timer standby state. Then, there is no need to perform so-called troublesome operations, and the timer standby state can be easily and reliably set.

Furthermore, when the timer standby operation is not performed, the standby locking member is moved to a non-operating position that is completely unrelated to the playback and recording operation rods and control members, so that normal playback or recording operations cannot be performed. At the same time, each operating rod is not locked in the trigger operating position one by one, and unnecessary movements of the operating device are eliminated to prevent malfunction of the operating device, and this effect is extremely useful in practice. It is something.
