Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Scope of the Invention] The present invention relates to an operating mechanism for a tape recorder, and particularly to improvements in means for controlling operating members for constant speed and high-speed tape running.

[Technical background of the invention and its problems]

Conventionally, tape recorders such as microcassette tape recorders have been provided with a pause mechanism for temporarily stopping the tape when running at a constant speed or at high speed.
This pause mechanism includes an electrical pause mechanism that operates electrically and a mechanical pause mechanism that operates mechanically.

By the way, in the case of the electric pause mechanism, when the pause is released during tape recording and playback, and the tape is then recorded and played again, there is a slight delay that prevents the start-up from occurring smoothly. There was a problem that there was no.

On the other hand, when a mechanical pause mechanism is used in a tape recorder that shares the constant speed and high speed drive mechanisms for the tape, the constant speed and fast forward systems are common to the reel stand and are controlled by adjusting the rotational speed of the motor. , and the rewind system was different. Therefore, in the pause state, the fast-forward system is controlled in the same way as the constant-speed system and becomes disabled.
The rewind system had operational problems because it could operate uncontrolled in the pause state.

[Purpose of the invention]

This invention has been made in view of the above circumstances, and is capable of smoothing the start-up after canceling a pause, and also eliminates operational problems with fast-forwarding and rewinding controls in a paused state. The purpose is to provide a mechanism.

[Summary of the invention]

That is, the present invention provides a tape recorder having a drive mechanism that shares a constant speed tape drive system and a high speed drive system, in which a high speed tape running operation mechanism is operated in conjunction with a pause operation mechanism that puts the constant speed tape drive system in a pause state. The device is configured to include a control mechanism that disables operation, releases the lock state of the high-speed running operation mechanism by a pause operation from the high-speed tape running state, and disables re-operation.

[Embodiments of the invention]

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 shows the overall structure of a microcassette tape recorder to which the present invention is applied. That is, on one side of the main chassis 11 formed of a metal plate material, pause, record, play, fast forward, rewind, and stop/eject operators 12 to 17 are provided with arrows A and 17, respectively.
It is supported movably in the B direction.

Further, a pair of reel stands 18 and 19 are rotatably supported at approximately the center of the main chassis 11. These reel stands 18 and 19 have
Gears 20 and 21 are formed coaxially, and the reel stands 18 and 19 and the gears 20 and 21 are configured to rotate together. Of these, the gear 20
A gear 22 is always meshed with the main chassis 11, and this gear is rotatably supported by a shaft 221 implanted in the main chassis 11.

Here, a capstan 23 is rotatably supported on a substantially perpendicular bisector connecting the rotation centers of the reel stands 18 and 19. This capstan 2
3 is inserted from the front side of the main chassis 11 to the back side without play, and the main chassis 11
The center axis of rotation of the flywheel 24 is formed on the back side of the flywheel 24 . The rotation of a motor 25 provided on one side of the main chassis 11 is transmitted to the flywheel 24 via a belt 26, and constantly drives the capstan 23 to rotate clockwise in the figure.

The main chassis 11 also has guide pins 27 and 28 on both sides of the capstan 23 for mounting a microtape cassette (not shown).
are provided for each.

Here, for example, when the playback operator 14 is pressed in the direction of arrow A, the playback slider 29 is interlocked and slid in the direction of arrow A. Then, the pinch roller 30 installed corresponding to the capstan 23 comes into contact with the capstan 23, and the recording/reproducing head 31 installed in parallel with the pinch roller 30 slides in the direction of arrow A, thereby touching the tape surface (not shown). is brought into contact with. At this time, the reel stand 18 is driven to rotate clockwise in the figure to reproduce the tape.

Further, the recording operator 13 can be operated in combination with the playback operator 14. Therefore, when the playback operation element 14 and the recording operation element 13 are operated in a combined manner, the reproduction slider 29 and the recording slider 32 are slid in the direction of arrow A in conjunction with each other. Then, as the playback slider 29 slides in the direction of arrow A, the pinch roller 30, recording/playback head 31, and reel stand 18 are in the same state as in the above playback state, and the recording slider 32 slides in the direction of arrow A. Along with this, the erasing head 33, which is arranged in parallel with the upper recording/reproducing head 31, is moved to enter the recording state.

Here, when the fast-forward operator 15 is operated in the direction of arrow A, the fast-forward slider 34 is interlocked and slid in the direction of arrow A, and the reel stand 18 is rotated clockwise in the figure at a higher speed than during playback. The state is set to fast forward.

Furthermore, when the rewind operator 16 is operated in the direction of arrow A, the rewind slider 35 is interlocked and slid in the direction of arrow A, and the reel stand 19 is driven to rotate at high speed counterclockwise in the figure, thereby rewinding the rewind. made with the state.

Here, the recording, playback, fast forward, and rewind operators 13 to 17 are each locked at the operating position by a locking mechanism to be described later. The locks at the operating positions of these operating elements 13 to 17 are released by operating the stop/eject operating element 17. This stop/eject operator 1
7 is a recording, playback, fast forward and rewind operator 13;
When any one of the controls 13 to 16 is operated, if you operate it once, each of the controls 13 to 16 will be unlocked, and if you operate it a second time, you will rotate an eject member (not shown) to eject the microcassette. It is designed so that you can do it.

The recording operation element 13 is configured to be locked at the operating position by a locking member 36 rotatably supported on the main chassis 11.

In addition, when the fast forward or rewind operators 15, 16 are operated in the playback state obtained by operating the playback operator 14, the fast forward or rewind operators 15, 1
6 is not locked in the operating position, and only while being pressed, the fast forward or rewind sliders 34, 35 are slid in the direction of arrow A, resulting in fast forward playback (queue) or rewind playback (review) status. . Furthermore, in a recording state in which the recording operator 13 and the playback operator 14 are operated in a combined manner, the rewind operator 16
When operated, only the recording operation element 13 is unlocked by the locking member 36, and the rewind operation element 16 is not locked in the operating position, but is in the rewind playback (review) state only while being pressed. becomes. When this pressing operation is stopped, the playback operator 14 remains locked at the operating position.
This puts the device into a playback state, and performs a so-called quick playback in which the previously recorded content can be immediately played back.

Here, when the pause operator 12 is operated in the playback state obtained by operating the playback operator 14, the rotation of the reel stand 18 is stopped by the pause operation mechanism 37, which will be described later, and the pinch roller 30 is moved from the capstan 23. Departed and recording/playback head 3
1 is released from the tape surface and is in a pause state.

By the way, the pose operator 12 is locked at the position where it is pressed in the direction of arrow A, and when the pose operator 12 is pressed again in the direction of arrow A from this locked position, the lock is released and it returns to the direction of arrow B. It has a push-button type operation in which it returns to its original position.

Next, the pause operation mechanism 37 operated in conjunction with the pressing operation of the pause operator 12 will be explained. First, as shown in FIG. 2, a notch 111 is cut out at one end of the main chassis 11.
is formed in the notch 111, and a pause mount 38 having a substantially U-shaped side surface is installed and attached with screws 39. This pose mount 38 has a through hole 381 formed in its back surface, and this through hole 381
One end of a pose member 40, which will be described later, is loosely inserted into the hole. A sliding shaft 382 is formed on the bottom of the pause mount 38 so as to face the notch 111 of the main chassis 11 .

Further, the pose operator 12 is attached to one end of a pose operating member 41, and the other end of the pose operating member 41 is projected toward the back side of the main chassis 11 and has an extending portion 411 in the operating direction. It is formed. This pose operation member 41 is formed with a notched engagement portion 412 corresponding to the through hole 381 of the pose mount 38, and one end of the pose member 40 is engaged with this engagement portion 412. has been done. The pose operation member 41 has a notch 417 formed near the pose operation element 12 on the back side of the main chassis 11, and a slide hole 41
3 is formed corresponding to the sliding shaft 382 of the pose mount 38, and a bent locking portion 414 is formed in a part of this sliding hole 413. The sliding shaft 382 of the pose mounting base 38 is connected to the sliding hole 413.
is inserted through a hole 421 formed at one end of the pause locking member 42, and a retaining ring 44 is attached to the tip thereof via a spring 43.
A recess 422 is formed in the pose lock member 42 so as to face the pose operation member 41 , and a cam portion 423 is located approximately at the center of the bottom surface of the recess 422 and corresponds to the bending locking portion 414 of the pose operation member 41 . It is formed by

Here, a bent portion 415 is formed in a part of the pose operation member 41, and this bent portion 415
A spring 45 is attached between the pose mount and the pause mount, so that the pose operation member 41 is biased in the reciprocal direction. The extended portion 411 of the pose operation member 41 has a long hole 41 extending in the operation direction.
6 is formed, and the shaft 112 implanted in the main chassis 11 is inserted into this elongated hole 416, so that the pose operation member 41 can be moved in the direction of arrows A,
It is supported slidably in the B direction. Therefore, when the pose operator 12 is pressed in the direction of arrow A, the bending locking portion 414 of the pose operation member 41
is locked by the cam portion 423 of the pose locking member 42, and the pose operator 12 is locked at the operating position. When the pose operator 12 is pressed again from this locked position, the bending locking portion 414 and the cam portion 423 are unlocked, and the spring 45 is released.
Due to the urging force, the pose operator 12 is returned to its original position.

Further, the extension portion 411 of the pose operation member 41
As shown in FIGS. 3a and 3b, the tip of the high-speed slider 46 is stacked with a predetermined space on one end of the high-speed slider 46 disposed on the back side of the main chassis 11. It is engaged with an engagement shaft 461 formed in 46. A substantially inverted triangular through hole 4 is provided at one end of the high speed slider 46.
62 is formed, and the shaft 113 implanted in the main chassis 11 is inserted into the through hole 462. Further, at the other end of the high speed slider 46,
A long hole 463 is formed, and the shaft 114 implanted in the main chassis 11 is inserted into the long hole 463. Therefore, the high speed slider 46
is supported rotatably around the other end while sliding in the directions of arrows C and D. This high-speed slider 46 has a bent piece 4 approximately in the center of one side thereof.
64 is formed, and this bent piece 464 and the shaft 11
A spring 47 is attached between the high-speed slider 46 and the high-speed slider 46 in the direction of arrow C. Further, a protrusion 465 is formed on the high-speed slider 46 so as to face the reel stands 18 and 19, and a shaft 466 is implanted in the protrusion 465 so as to face the main chassis 11. This axis 4
66, a gear pulley 48 is rotatably supported, and a gear portion 49 of this gear pulley 48 protrudes toward the surface side of the main chassis 11 and connects to the gear 22.
and the gear 21 of the reel stand 19, and is normally meshed with the gear 22 of these.
Therefore, when the pose operation member 41 is slid in the direction of arrow A, the engagement shaft 4 of the high-speed slider 46
61 is pressed, and this high-speed slider 46 is rotated clockwise in the figure while sliding slightly in the direction of arrow D. Therefore, the gear pulley 48 supported by the high-speed slider 46 is rotated so that its gear portion 49 is separated from the gear 22, and the reel stand 18 is rotated.
The rotation of is stopped.

Here, a control mechanism for the pinch roller 30 that is controlled in conjunction with the pressing operation of the pause operator 12 will be explained. That is, as shown in FIGS. 4a and 4b, one end of a substantially U-shaped pinch lever 50 is rotatably supported on a shaft 115 installed on the main chassis 11. The pinch roller 30 is rotatably supported at the end. The pinch lever 50 has a notch 501 cut out in the middle of its lower surface, and is biased counterclockwise in the drawing by a torsion spring (not shown).

Further, as described above, the pause member 40 whose one end is engaged with the engaging portion 412 of the pause operation member 41 has its other end rotated integrally with the one end of the pinch lever 50 around the shaft 115. Supported for free movement. At the other end of this pause member 40, a bending engagement portion 401 is provided at the notch 5 of the pinch lever 50.
01, and this bent engagement portion 401
is engaged with the notch 501. Therefore,
For example, in a tape playback state, when the pause operator 12 is pressed and the pause operating member 41 is slid in the direction of arrow A, the pause member 40 is rotated clockwise in the figure in conjunction with this. be moved. At this time, the bending engagement portion 401 of the pause member 40 presses the cutout portion 501 of the pinch lever 50 to rotate the pinch lever 50 clockwise in the figure, and detach the pinch roller 30 from the capstan 23. .

Next, the operation of the rotation transmission mechanism will be explained. First, when the playback operator 14 is pressed in the direction of arrow A, the playback slider 29 is slid in the same direction, and as described above, the pinch roller 30 comes into contact with the capstan 23 via the tape, and at the same time the recording/playback is performed. A head 31 is brought into contact with the tape surface. On the other hand, a switch (not shown) is turned on in conjunction with the regeneration operator 14 to rotate the motor 25, and the rotation of the motor 25 is transmitted to the gear pulley 4 via the belt 26.
8 and the flywheel 24. Therefore, as shown in FIG. 5, the gear pulley 48 has its gear portion 49 meshing with the gear 20 of the reel stand 18 via the normal gear 22, so that the reel 18 is rotationally driven and the tape is rolled. It is used for replay running.

Further, as shown in FIG. 3, when the recording and playback operators 13 and 14 are pressed together in the direction of arrow A,
In conjunction, the recording and playback sliders 32 and 29 are slid in the same direction. Among these, as the playback slider 29 slides, the pinch roller 30 and the recording/playback head 3
1, etc. are positioned in the same manner as in the above-described playback state, and as the recording slider 32 slides, the erasing head 33 is slid in the same direction and brought into contact with the tape surface.
This is where tape recording takes place.

Here, in the rotation transmission mechanism when the fast-forwarding operator 15 is operated, as shown in FIG.
Since the gear portion 49 is in mesh with the gear portion 49 via the gear 22, the tape can be fast-forwarded in this state. Therefore, when the fast-forward operator 15 is pressed in the direction of arrow A, a switch (not shown) is turned on in conjunction with this operation, causing the motor 25 to rotate at a higher speed than in the recording and playback state, and the tape is Fast forward running is performed.

Further, when the rewind operator 16 is operated, the rotation transmission mechanism is as shown in FIG.
When the rewind slider 35 is pressed in the direction of arrow A, the rewind slider 35 is slid in the same direction. Here, the high-speed slider 46 that engages with a part of the rewinding slider 35 is slid in the direction of the arrow C as the rewinding slider 35 slides in the direction of the arrow A. Gear pulley 48 supported by
is moved. Therefore, the gear part 49 of the gear pulley 48 is separated from the gear 22 and the reel stand 19 is removed.
The reel stand 19 is rotated by being meshed with the gear 21, and the tape is rewinded.

Incidentally, in conjunction with the operation of the rewind operator 15, a switch (not shown) is turned on, and the motor 25 is rotated at a higher speed than in the recording and reproducing states, thereby causing the tape to run at a high speed.

Here, the pose action performed by operating the pose operator 12 will be explained. First, in the state where the tape is being played back by operating the playback operator 14 described above, as shown in FIG.
When pressed in the direction of arrow A, the pose operation member 4
1 is slid in the same direction. Therefore, as described above, since the tip of the extending portion 411 of the pose operation member 41 presses the engagement shaft 461 of the high-speed slider 46 in the direction of the arrow A, the high-speed slider 46 slightly moves toward the direction indicated by the arrow D.
While being slid in the direction, it is rotated clockwise in the figure around the other end. Therefore, by interlocking the gear pulley 48 supported by this high-speed slider 46, the gear portion 49 of the gear pulley 48 is disengaged from the gear 22, and the pose operation member 41 is locked at the operation position by the lock mechanism 37 described above. Ru. At this time, the above-mentioned pose operation member 4
The pause member 40 that engages with the first engaging portion 412 is
Rotated as the pose operation member 41 slides,
The pinch roller 30 is removed from the capstan 23 and the recording/reproducing head 31 is removed from the tape surface, thereby creating a pause state in which the playback of the tape is stopped.

In addition, when the pause operator 12 is pressed in the direction of arrow A in the fast-forward running state of the tape formed by operating the fast-forward operator 15 described above, the high-speed slider 46 is operated, the gear pulley 48
The gear portion 49 is disengaged from the gear 22, the rotation of the reel stand 18 is stopped, and the pause operation member 41 is locked at the operation position, at which point the fast-forwarding of the tape is released.

Here, in the state in which the tape is rewinding by operating the rewind operator 16 described above, when the pause operator 12 is pressed in the direction of arrow A as shown in FIG. are slid in the same direction. Therefore, as described above, since the tip of the extending portion 411 of the pose operating member 41 presses the engagement shaft 461 of the high-speed slider 46 in the direction of arrow A, the high-speed slider 46 is slightly slid in the direction of arrow D while It is rotated clockwise in the figure around the end. Therefore, by interlocking the gear pulley 48 supported by this high-speed slider 46, the gear portion 49 of the gear pulley 48 is disengaged from the gear 21 of the reel stand 19, and the pause operation member 41 is locked at the operation position. Tape rewinding is released.

Next, play, fast forward and rewind controls 14,1
A lock mechanism and a lock control mechanism in which locks 5 and 16 are respectively locked in the operating position will be explained. That is, as shown in FIG.
1,341 is formed, and this through hole 291,341
Lock portions 292 and 342 are respectively formed at predetermined positions on one side of the. Of these, the fast-forward slider 34 has a locking portion 343 at a predetermined position on one side thereof.
is formed corresponding to the lock portion 341. on the other hand,
The rewinding slider 35 is formed with a protruding lock portion 351 at a predetermined position on the other side.
A locking portion 352 protruding from a predetermined position on one side thereof is formed corresponding to the locking portion 351 .

Here, on the back side of the main chassis 11 corresponding to the playback, fast forward and rewind sliders 29, 34 and 35, a pause slider 51 and a lock plate 52 are stacked at predetermined intervals so as to be substantially orthogonal to each other. Ru. The pose slider 51 and the lock plate 52 have elongated holes 511 and 52 at both ends thereof.
1, 512, 521 are formed in correspondence with each other, and in the elongated holes 511, 521 at one end and the elongated holes 512, 522 at the other end, shafts 116, 1
17 is inserted so that it is slidably supported in the directions of arrows C and D. Above pose slider 51
And the lock plate 52 has a pressing part 51 at one end thereof.
3,523 are formed respectively, and this pressing part 51
3,523 are the pose operation members 41, respectively.
It is interposed in the notch 417 of. Among these, bending locking portions 513 and 514 are formed on the pause slider 51, corresponding to the locking portions 343 and 352 of the fast forward and rewind sliders 34 and 35, respectively. On the other hand, the locking plate 52 is formed with a bent locking portion 524 having a predetermined dimension l' corresponding to the locking portion 292 of the reproducing slider 29, and a locking portion 524 of the fast-forwarding/rewinding slider 34, 35. 341, 352, bending locking parts 525, 5
26 are each formed with a predetermined dimension l. Therefore, the playback, fast forwarding and rewinding controls 14,1
5 and 16 are lock portions 291 of the playback, fast forward and rewind sliders 29, 34 and 35 in the operating state;
341 and 351 are respectively engaged with the bending engagement portions 524, 525 and 526 of the lock plate 52, and are locked in the operating position.

Now, suppose that the pose operating member 41 is slid in the direction of arrow A by pressing the pause operating element 12 as shown in FIG. 10B while the fast forward operating element 15 is being operated. Then, this pose operation member 4
The pose slider 51 and the pressing parts 513, 523 of the lock plate 52, which were interposed in the notch 417 of 1, are engaged with one end of the protruding piece removed from the notch 417 and are pressed in the direction of arrow D. The pose slider 51 and the lock plate 52 are slid in the direction of arrow D. At this time, the fast-forwarding slider 34 is disengaged from its lock portion 342 and the bent locking portion 525 of the lock plate 52, and is returned to its original position by the biasing force of a spring (not shown). Therefore, as shown in FIG. 10c, the locking portions 343, 352 of the fast forward and rewind sliders 51, 52 are opposed to the bending locking portions 514, 515 of the pause slider 51, so that
The fast-forward and rewind operators 15 and 16 are locked at the return position and are prevented from being operated, but the playback operator 14 is operable.

Further, when the pause operator 12 is operated while the playback operator 14 is being operated, the playback slider 29 has a bending locking portion 524 of the locking plate 52 corresponding to the locking portion 292 of the playback slider 29. Since it is formed with l', the lock cannot be released, and once the pause state is released, the tape will be played again.

If the pause operator 12 is operated while the rewind operator 16 is being operated, the operation will be substantially the same as when the pause operator 12 is operated while the fast forward operator 15 is being operated. When this is done, the rewind operator 16 is released from its lock and returned to its original position by the biasing force of a spring (not shown). Therefore, the fast forward and rewind operators 15 and 16
Since the locking portions 343, 352 and the bending locking portions 514, 515 of the pause slider 51 are opposed to each other, the fast forward and rewind operators 15, 1
6 is locked at the return position and its operation is prevented, so that it is no longer possible to do so, but the playback operator 14 can be operated.

Furthermore, although the lock control mechanism described above is realized using the pause slider 51 and the lock plate 52, as a modification, only the lock plate 52 may be used to achieve the same effect as the playback, fast forward and rewind operators 14, 1.
It is possible to control 5,16. That is, as shown in FIG. 11a, the fast forward slider 34
A locking portion 344 protruding from the through hole 341 is formed at a predetermined position opposite to the lock portion 342 . On the other hand, the rewinding slider 35 has a through hole 353.
A lock portion 354 is formed at a predetermined position in this through hole 353.
A locking portion 355 protrudes at a predetermined position opposite to 54.
is formed.

Here, for example, fast forward or rewind operator 1
When the pause operator 12 is operated while 5 and 16 are being operated, the lock plate 52 is slid in the direction of arrow D, so that the fast forward or rewind sliders 34 and 35 are moved.
The lock portions 342, 354 and the lock plate 52
The locking with the bending locking portions 525, 526 is released, and the spring is returned to the original position by the biasing force of the spring.
Therefore, as shown in FIG. 11b, the fast forward and rewind sliders 34 and 35 are
55 and the bent locking portions 525, 526 of the lock plate 52
Since the fast-forward and rewind operations 15 and 16 are locked at the return position and are prevented from being operated, the playback operation element 14 can be operated. .

Furthermore, if the pause operator 12 is operated while the playback operator 14 is being operated, the playback slider 14 will not be unlocked again as described above, and will be reactivated once the pause is released. The tape is played back.

In each of the above embodiments, the fast forward and rewind operators are canceled by operating the pause operator when the tape is fast forwarding and rewinding, and the fast forward and rewind operators cannot be operated in the pause state. It is something.

〔Effect of the invention〕

As described above, it is an object of the present invention to provide a good operating mechanism for a tape recorder that can smoothly start up after a pause is released, and can prevent malfunctions in the operation of the fast-forward and rewind operators in the pause state. I can do it.
