Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an improvement in the soft touch operation mechanism of a tape recorder.

As is well known, in a tape recorder, the various controls used to set the tape in a predetermined running state (recording, playback, fast forward, rewind, etc.) and stop running are light and easy to operate. So-called soft-touch operation has been implemented. The mechanism for performing this soft touch operation is such that when the desired operator is lightly moved in the operating direction without reaching the normal operation position, the rotational drive switch of the operator movement motor is turned on, and the rotational force of the motor is then used. The operator is being moved in the operating direction.

However, in the conventional soft touch operation mechanism as described above, a switch, a motor, etc. must be provided for each type of operator, making the configuration extremely complex and likely to be large. There is a problem in that it can only be applied to high-quality tape decks, etc., and is not suitable for, for example, small portable tape recorders that use batteries.

Therefore, there is a strong demand for the development of a soft touch operation mechanism that consumes extremely little power so that it can be fully applied to conventional battery-powered tape recorders. In addition, recent soft-touch mechanisms in particular do more than just reduce power consumption.
For example, the soft touch operation mechanism can be made into a unit so that it can be widely applied to various types of tape recorders, the time from the start to the end of the operation of the soft touch operation mechanism can be shortened, and protection can be provided when the battery power is consumed during operation. It is desired that sufficient consideration be given to the details in terms of structure, operation, and maintenance, such as taking countermeasures.

This idea was made based on the above circumstances, and when performing a so-called follow-up operation in which one of the operators of a tape recorder is operated in advance and another operator is operated, the soft touch operation mechanism is activated. An object of the present invention is to provide an extremely good soft touch operation mechanism for a tape recorder that does not impose unnecessary load on the motor that is the source of the tape recorder.

Hereinafter, one embodiment of this invention will be described in detail with reference to the drawings. FIGS. 1 and 2 show a unitized operating section, and first a brief overview of this operating section will be explained. That is, numerals 11 to 16 in the figure are a stop operator, a recording operator, a rewind operator, a playback operator, a fast-forward operator, and a pause (pause) operator, respectively. Each of these operators 11 to 16 is arranged to be movable in the directions of arrows A and B in the figure, respectively. Of the respective operators 11 to 16, the record, rewind, playback, and fast-forward operators 12 to 15 are adapted to be rotated at the operating positions pressed in the direction of arrow A, respectively. Further, the locks at the operating positions of the recording, rewind, playback, and fast-forward operators 12 to 15 are released by pressing the stop operator 11 in the direction of arrow A.
Note that this stop operation element 11 is not locked in the operating position. In addition, the above pose operator 1
6 is a well-known device in which it is locked at the operating position where it is pressed in the direction of arrow A, and when it is pressed slightly again in the direction of arrow A from the locked position, the lock is released and returned to the direction of arrow B to return to its original position. It uses a push-push type operation.

The stop, record, rewind, play, fast forward, and pause operators 11 to 16 are biased in the non-operating direction, that is, in the direction of arrow B, by springs 17 to 22, respectively, as shown in FIG. . Here, the springs 17 to 22 are of a type that does not have a very strong biasing force, and the recording, rewinding, playback and fast forwarding controls 12 are
15 to 15 are for simply moving the lock lever, push lever, gear lock lever, etc. to predetermined positions when pressed, and the details will be described later. They also move the head chassis, rewind or fast forward idler, etc. of the tape recorder mechanism to predetermined operating positions. Since the operation slider is not directly operated, it is extremely light and easy to operate.

The stop operator 11 also controls recording, rewinding,
Since it only releases the lock at each operation position of the playback and fast-forward controls 12 to 15, and does not return the direct operation slider from the predetermined operation position to its original state, the operation can be made extremely light. be. Furthermore, the pause operation element 16 only moves the lock lever, push lever, gear lock lever, etc. to a predetermined position, and directly operates the pause operation slider that moves the playback idler, pinch roller, etc. of the tape recorder mechanism. Since it is not a physical object, it is light and easy to operate.

That is, the stop, record, rewind, play, fast forward, and pause operators 11 to 16 are used to select and set a desired state from among multiple types of operating states and stop states of the tape recorder, respectively, and to directly operate the tape recorder. It is not intended to be activated or deactivated.

FIG. 3 shows a specific configuration of such an operating section. That is, each of the above-mentioned operators 11 to 16 is attached to one end of each of the operating members 23 to 28, respectively. And each of these operating members 2

9 is attached.

Here, elongated holes 231 to 281 extending in the longitudinal direction of the operating members 23 to 28 are formed at each end of each of the operating members 23 to 28, respectively. Then, each of the long hole portions 231 to 281
A shaft 40 passes through the shaft 40, and both ends of the shaft 40 have through holes 341 formed in the fittings 34, 35,
351 and are respectively fitted and supported. Further, this shaft 40 is connected to leg portions 41 provided at both ends of a gear lock lever 41 that is formed to straddle the operating members 24 to 28 other than the operating member 23.
The gear lock lever 41 is rotatably supported through the through holes 413 and 414 of No. 1,412. A gear lock pin 415 is provided approximately at the center of the gear lock lever 41 and projects outward.
In addition, at the right end of the gear lock lever 41 in the figure,
The gear lock lever 41 engages with the switch 38.
A projecting piece 416 is formed that can turn the switch 38 on and off in accordance with the rotation of the switch 38.

Here, the operating members 24 to 28 other than the operating member 23 are provided with the aforementioned lock lever, push lever, and the like. FIG. 4 shows the state in which the lock lever and push lever are installed. Here, only the operating member 26 to which the regeneration operator 14 is attached will be explained, and the other operating members 2
4, 25, 27, and 28 have similar configurations, so a description thereof will be omitted.

That is, the operation member 26 has two side plates 262 and 263 (only one side plate 262 is shown in FIG. 4) aligned with each other from the substantially central portion to the other end to which the playback operation element 14 is not attached. It is formed so that it can be installed. And both side plates 262, 263
connects the upper end center part and the other end part in the figure to the connecting part 2
64,265. here,
A lock lever 42 is supported by a shaft 43 approximately at the center of the operating member 26 and between the two side plates 262 and 263 so as to be rotatable in the directions of arrows C and D in the figure. The lock lever 42 is formed into a substantially U-shape, with its base end 412 protruding downward from the operating member 26 in the drawing, and the distal end portions of two pieces facing each other projecting upward from the operating member 26 in the drawing. It is supported by the following. Furthermore, a stepped portion 422 is formed at the tip of one of the two mutually opposing pieces of the lock lever 42. moreover,
The above-mentioned spring 21 is engaged between the base end 421 of the lock lever 42 and the mounting base 29, and urges the lock lever 42 to rotate in the direction of arrow C, and simultaneously operates the lock lever 42. The member 26 is urged in the direction of arrow B.

Further, the lock lever 42 and the connecting portion 26
4, a playback operation slider 44 is interposed. The playback operation slider 44 is supported by, for example, a main chassis 49 of the tape recorder mechanism so as to be slidable in the vertical direction in the figure.
When it is slid upward in the figure, it moves the head chassis, playback idler, etc. (not shown) to a position corresponding to the tape playback state. A notch 441 is formed in the lower part of the reproduction operation slider 44 in the figure. Furthermore, in the upper part of the notch 441 of the playback operation slider 44, there is a
An engagement hole 422 is formed at a position corresponding to the stepped portion 422 of the lock lever 42.

Here, one end of the push lever 45 is inserted into the notch 441 of the regeneration operation slider 44, and the tip of the one end is connected to the lock lever 4.
It faces the axis 43 of No. 2. This push lever 45 has its substantially central portion at one end of a substantially L-shaped transmission lever 46 which is rotatably supported by the shaft 40 being inserted into the corner between the side plates 262 and 263 of the operating member 26. It is supported by the portion 461 by a shaft 47 so as to be rotatable in the directions of arrows E and F in the figure. Also,
The other end 462 of the transmission lever 46 faces the lower end of the gear lock lever 41 in the drawing. Here, the other end of the push lever 45 is formed with an engaging portion 451 against which a drive slider, which will be described later, comes into contact. Further, the spring 48 is engaged between the locking portion 452 formed on the lower side of the push lever 45 in the figure and the locking portion 297 formed on the mounting base 29, so that the push lever 45 is moved around the shaft 47. The shaft 40 is biased in the direction of arrow F, and the transmission lever 46 is biased counterclockwise in the figure with the shaft 40 as the center.

Here, a playback operation slider 44 is interposed between the lock lever 42 and the connecting portion 264 of the operation member 26 to which the playback operation element 14 is attached, but other functions such as recording, rewinding, fast forwarding, etc. Between each lock lever provided on each operation member 24, 25, 27, 28 to which the pose operation elements 12, 13, 15, 16 are attached and the connecting part, there is a recording,
There are operation sliders for rewinding, fast forwarding, and pausing.

In this state, the gear lock lever 41
The gear lock pin 415 is inserted into a through hole 511 formed in a predetermined portion of a cam gear 51 which is rotatably supported by the main chassis 49 of the tape recorder mechanism section about a rotating shaft 50. This cam gear 51 has a notch 5 in a part as shown in FIG.
12 are formed. And this cam gear 5
A gear 54 fitted onto a rotating shaft 53 of a flywheel 52 rotatably supported by the main chassis 49 is provided at a position corresponding to the first notch 512 . In addition, the above flywheel 52
The rotating shaft 53 is extended to form a capstan. Furthermore, the rotational force of a motor 55 is transmitted to the flywheel rail 52 via a belt 56.

Here, the cam gear 51 has a notch 51
2 is in a position facing the gear 54, the through hole 5
The gear lock pin 415 of the gear lock lever 41 is inserted into the gear lock pin 415 of the gear lock lever 41. Further, when the notch 512 of the cam gear 51 is in a position facing the gear 54, the cam gear 51 is urged to rotate in the direction of arrow G in the figure by the action of a spring, which will be described later. Since it is inserted into the hole 511, the cam gear 51
is prevented from rotating, and the cam gear 51 and gear 54 do not mesh with each other.

Furthermore, the gear lock pin 415 of the gear lock lever 41 is connected to the through hole 511 of the cam gear 51 by a spring 57 that is engaged between the gear lock lever 41 and the main chassis 49.
is biased in the direction of intervening within the body.

Here, the cam gear 51 is formed with a cam 513 as shown in FIG.
3 is formed in a substantially semicircular shape as shown in the figure,
The arcuate portion on the right side of the rotation axis 50 in the figure is curved so as to rise sharply, while the arcuate portion on the left side of the rotation axis 50 in the figure is curved so as to rise more gently.
The cam 513 is in a position where the notch 512 of the cam gear 51 faces the gear 54, that is, in a state where the gear lock pin 415 of the gear lock lever 41 is inserted in the through hole 511 of the cam gear 51, the flat portion 514 of the cam 513 is formed in a substantially L-shape, and the corner portion of the flat portion 514 forms a drive lever 59 which is rotatably supported by the main chassis 49 by a rotating shaft 58.
The second portion is arranged to face one of the first portions.

Furthermore, a leaf spring 60 is provided on one side of the drive lever 59 to extend toward the tip.
This plate spring 60 has a tip end that is connected to the drive lever 5.
A substantially U-shaped locking portion 5 formed at the tip of one side of 9
91 is locked. In addition, the drive lever 5
The other end of the drive lever 9 is engaged with a switch 61, which will be described later, and is turned on and off in accordance with the rotation of the drive lever 59.

Here, the leaf spring 60 of the drive lever 59 is
The drive slider 62 is disposed opposite to one side of the drive slider 62, which is formed in a substantially L-shape. This drive slider 62 has screws 63 and 6 inserted into elongated holes 621 and 622, respectively, which are formed long in the vertical direction at predetermined positions.
3 is inserted through the main chassis 49 and screwed onto the main chassis 49, so that the main chassis 49 is slidably supported in the vertical direction in the figure. Further, a spring 64 is engaged between the other part of the drive slider 62 and one part of the drive lever 59, and if the drive slider 62 is used as a reference,
The drive lever 59 is biased clockwise in the figure. At this time, the drive lever 59 is engaged with the flat part 514 of the cam 513, and its rotation in the clockwise direction in the figure is caused by the extension of one part of the drive lever 59 formed on the other part of the drive slider 62. The protruding portion 623 is configured to contact the protruding portion 623, thereby applying a rotational force in the direction of the arrow G to the cam gear 51. Also,
This drive slider 62 is urged upward in the figure by a spring (not shown).

The operation of the above configuration will be explained below. First, as shown in FIG. 7, the playback operator 14 is pressed in the direction of arrow A. Then, the operating member 26 also moves in the same direction and is locked at the operating position by a locking mechanism to be described later, and the lock lever 42 supported by the operating member 26 via a shaft 43 has a stepped portion 422 that is connected to the regeneration operating slider. 4
By being in contact with the wall surface of 4, the spring 2
It is rotated in the direction of arrow D against the urging force of 1. That is, conversely, at this time, the stepped portion 422 of the lock lever 42 is pressed against the wall surface of the regeneration operation slider 44 by the biasing force of the spring 21.

Furthermore, when the operating member 26 is moved in the direction of arrow A, the shaft 43 comes into contact with one end of the push lever 45, and the push lever 45 is also moved in the direction of arrow A against the biasing force of the spring 48. At this time, the engaging portion 451 of the push lever 45 reaches directly below the drive slider 62 in the figure. Then,
A transmission lever 46 whose one end 461 is rotatably supported by the push lever 45 via a shaft 47
is rotated clockwise in the figure around the shaft 40. At this time, the other end 462 of the transmission lever 46
comes into contact with the lower end of the gear lock lever 41 in the figure,
The gear lock lever 41 is rotated counterclockwise in the figure. Therefore, the gear lock pin 415 is removed from the through hole 511 of the cam gear 51.

Then, as mentioned earlier, the cam gear 51 is normally urged to rotate in the direction of the arrow G in FIG. Therefore, when the gear lock pin 415 is removed from the through hole 511, the cam gear 51 is rotated in the direction of arrow G and meshes with the gear 54. Here, the motor 55 is always in the sixth
It is rotating in the direction of arrow H in the figure, and the flywheel rail 52 and gear 54, which are connected to the motor 55 through a belt 56 so as to be able to transmit rotational force, are also rotating in the same direction. Therefore, the cam gear 51 meshed with the gear 54 continues to rotate in the direction of arrow G as shown in FIG.

At this time, due to the rotation of the cam gear 51, the cam 5
13 also rotates, and its arcuate portion abuts one portion of the drive lever 59, and the curved bulge portion rotates the drive lever 59 counterclockwise in the figure about the rotation shaft 58. The leaf spring 60 provided on the drive lever 59 is connected to the drive slider 6.
2, and the drive slider 62 is slid downward in the figure. Then, as shown in FIG. 9, the drive slider 62 comes into contact with the engaging portion 451 of the push lever 45, and the push lever 45 is rotated about the shaft 47 in the direction of arrow F in the figure. Therefore, the other end of the push lever 45 separates from the shaft 43, engages with the notch 441 of the regeneration operation slider 44, and pushes the regeneration operation slider 44 upward in the figure.

When the playback operation slider 44 reaches a predetermined operation position, it will no longer move upward in the figure from that position, and the push lever 45 will also no longer rotate. However, since the rotation stroke of the drive lever 59 is set to be long with some allowance, the rotation of the push lever 45 stops and the drive slider 6
Even if the movement of No. 2 is stopped, the drive lever 59
It is rotated clockwise in the figure. At this time, the overstroke of the drive lever 59 is absorbed by the leaf spring 60.

Here, one end of the push lever 45 is attached to the shaft 43.
Even if the drive slider 62 is separated from the holding part 4 formed near the engaging part 451 of the push lever 45
53, the push lever 45 and drive slider 62 are held together by the biasing force of the spring 48.
and will not leave carelessly. Further, while the cam gear 51 is rotating, the gear lock pin 415 is pressed against a portion of the cam gear 51 where the through hole 511 is not provided by the spring 57 (see FIG. 5).

As mentioned above, when the playback operation slider 44 is pushed upward in the figure, the headshield, playback idler, etc. are moved to positions corresponding to the tape playback state, and the playback operation is performed here. . Here, playback operation slider 44
When the lock lever 42 is slid upward in the figure, the engagement hole 442 formed in the regeneration operation slider 44 reaches a position corresponding to the stepped portion 422 of the lock lever 42. Then, the lock lever 42 moves to its stepped portion 422.
is pressed against the wall surface of the regeneration operation slider 44, so that the stepped portion 422 is pressed against the wall surface of the regeneration operation slider 44.
The regeneration operation slider 44 is held in the pushed-up position. Then, the cam gear 51 rotates once, and the notch 512
When the cam 513 reaches a position facing the gear 54, the flat portion 514 of the cam 513 is again in a position corresponding to one portion of the drive lever 59. At this time, the drive slider 62 is slid upward in FIG. 8 by the action of the spring, and at the same time the through hole 511 of the cam gear 51
comes to a position corresponding to the gear lock pin 415, so the gear lock pin 41 is moved as shown in FIG.
5 is inserted into the through hole 511, and the rotation of the cam gear 51 is prevented. Furthermore, since the drive slider 62 separates from the engaging portion 451 of the push lever 45, the push lever 45 is pulled by the biasing force of the spring 48, and the transmission lever 46 is rotated counterclockwise in the figure about the shaft 40 to a position. will be moved. Therefore, the engaging portion 451 of the push lever 45 is located outside the movement path of the drive slider 62. Then, the reproduction operation slider 44 is locked at the position pushed up by the stepped portion 422 of the lock lever 42, and the tape reproduction operation is maintained.

Furthermore, the above operations can be similarly explained for the other recording, rewind, fast forward, and pause operators 12, 13, 15, and 16. During operation, the push levers corresponding to the respective operators 12, 13, 15, and 16 are moved to a position where they can be engaged with the drive slider 62, the gear lock pin 415 of the gear lock lever 41 is disengaged from the through hole 511 of the cam gear 51, and each The operation sliders (recording, rewind, fast forward, and pause operation sliders) are moved and locked at the respective positions.

Here, as means for biasing the cam gear 51 in the direction of arrow G in FIG.
If the driving slider 62 is urged upward in the figure with a stronger urging force than the leaf spring 60, one end of the driving lever 59 will engage with one end of the flat part 514 of the cam 513. Arrow G for cam gear 51
It can be biased in the direction.

Therefore, according to the above configuration, the operating section is made into a unit and the operating section is connected to each operating member 24.
The engaging portions of the push levers provided in the push levers 28 to 28 are attached to various tape recorders so that they can be freely engaged with and disengaged from the corresponding operating sliders of the tape recorder mechanism, so the same operating portion can be used with various types of tape recorders. It can be widely applied to tape recorders, and tape recorders can be easily operated by soft touch. In addition, since the operation of each operation slider corresponding to a plurality of operators is performed by the same drive source, that is, the rotational force of the flywheel 52, it is not necessary to install a motor etc. for each operation slider as in the conventional case. Therefore, the configuration is extremely simple.

Here, as shown in FIG. 10, when the playback operator 14 is operated, the push lever 45
Because one end is inserted into the notch 441 of the regeneration operation slider 44 by the action of the spring 48,
The engaging portion 451 of the push lever 45 is located outside the movement path of the drive slider 62. For this reason,
When the fast-forward and rewind operators 15 and 13 are operated in the above-mentioned playback state while trying to perform fast-forward playback (queuing) and rewind playback (review), the fast-forward and rewind operators 15 and 13 become attached. In conjunction with the movement of the operating members 27 and 25, the gear lock pin 415 of the gear lock lever 41 is disengaged from the through hole 511 of the cam gear 51, and the drive slider 62 is then moved downward in FIG. 10 as described above. However, the drive slider 62 does not engage with the push lever 45 and the operating members 27, 2
By engaging with the engaging portion of the push lever provided at 5 and rotating the push lever, the fast-forwarding and rewinding operation sliders are operated, thereby performing queue and review operations.

Therefore, the drive slider 62 is the operating member 2
The push levers 7 and 25 are engaged to operate the fast forward and rewind operation sliders, but the push lever 45 corresponding to the playback operator 14 is not engaged, so the movement force of the drive slider 62, that is, the rotation of the cam gear 51, is unnecessary. Therefore, the load on the motor 55 can be reduced, and power consumption can be reduced.
This is suitable for battery-powered tape recorders. In addition to the queue and review mode, when the pause operator 1 is being operated while the playback operator 14 is being operated.
The same applies when operating the drive slider 62.
engages only with the push lever of the operating member 28 to which the pose operator 16 is attached, and the pose operating slider is operated. In short, when performing a so-called follow-up operation in which one of the operators 12 to 16 is operated in advance and the other operators 12 to 16 are operated, the operator 12 to 16 that was operated earlier is The corresponding push levers are located outside the movement path of the drive slider 62, so that only the push levers corresponding to the operators 12 to 16 can later engage with the drive slider 62. Therefore, since the motor 55 can only move one push lever during the follow-up operation, there is no need to apply unnecessary load.

As described above, the feature of this invention is that when the operators 12 to 16 are operated, the push lever corresponding to the operators 12 to 16 is moved out of the movement path of the drive slider 62. This is the part that becomes.

Next, details of the drive lever 59 will be explained. That is, as shown in FIG. 11, the drive lever 59 is made of a synthetic resin material with a smooth surface so that it can easily rotate with respect to the main chassis 49. A pair of pins 592 and 593 are formed protruding from one side of the drive lever 59, and screw holes 594 and 595 are formed. A reinforcing plate 65, which is formed by bending the leaf spring 60 on one side, is attached to one side of the drive lever 59. This reinforcing plate 65 is attached. The reinforcing plate 65 is made of a metallic material, and has through holes 651 to 654 formed at positions corresponding to the pins 592, 593 and screw holes 594, 595 of the drive lever 59, respectively. Then, the pins 592, 593 of the drive lever 59 are fitted into the through holes 651, 652 of the reinforcing plate 65, and the through holes 653, 654 are fitted with the screws 661, 654.
662 is inserted into the screw hole 59 of the drive lever 59.
4,595, respectively, to be attached to the drive lever 59. Note that at this time, the tip of the leaf spring 60 is connected to the drive lever 59.
It is locked by a locking part 591 formed at one end of the.

Therefore, the leaf spring 60 and the reinforcing plate 65 are integrally formed, and by attaching the reinforcing plate 65 to the drive lever 59, the leaf spring 60 is also attached at the same time, which simplifies the installation work. This is easy and the drive lever 59 can be sufficiently reinforced. Here, since the drive lever 59 has a complicated shape as shown in FIG. 11 and needs to have a smooth surface so that it can be easily rotated, it is convenient to construct it by molding a synthetic resin material. It is. However,
Since the drive lever 59 is required to move the drive slider 62, a bending force in the direction of the arrow in the figure is applied to the drive lever 59, and the mechanical strength of the drive lever 59 is low if it is made only of synthetic resin. Therefore, it becomes necessary to reinforce the drive lever 59 with the reinforcing plate 65. Therefore, with the above-described configuration, the reinforcement degree 65 and the attachment of the leaf spring 60 can be performed at the same time, which is extremely effective.

Here, as shown in FIG. 12, the motor 5
5 is connected to power terminals 68 and 6 via a governor circuit 67.
9 power is being supplied. Also,
Both ends of the governor circuit 67 are connected to both contact pieces 381 and 382 of the switch 38, respectively. In a normal tape running state, the motor 55 is supplied with electric power obtained by reducing and stabilizing the electric power at the power supply terminals 68 and 69 by the governor circuit 67, and the motor 55 is rotated at a constant speed. On the other hand, the operator 12
16 to 16, the gear lock lever 41 moves its gear lock pin 415 in conjunction with this operation.
is rotated in a direction in which the cam gear 51 is removed from the through hole 511 of the cam gear 51. At this time, the switch 38 has its contact piece 381 connected to the protruding piece 416 of the gear lock lever 41.
, and both contact pieces 381 and 382 are brought into contact with each other. Therefore, the governor circuit 67 is short-circuited,
The power from the power terminals 68 and 69 is directly connected to the motor 55.
supplied to Therefore, the motor 55 is rotated at a higher speed and higher torque than when the tape is running.

For this reason, the cam gear 51 meshed with the gear 54
can be rotated quickly in the direction of arrow G in the figure. The fact that the rotational speed of the cam gear 51 can be made faster means that the operating elements 12 to 16 can be rotated faster.
After the gear lock pin 415 of the gear lock lever 41 is removed from the through hole 511 of the cam gear 51 by operating the cam gear 51, the cam gear 51 rotates and the operating sliders corresponding to the operated operators 12 to 16 are moved to the operating position. This means that the time it takes can be shortened.

Note that FIG. 13 shows the case where power is supplied to the motor 55 via the governor circuit 67 and the case where the governor circuit 67
When power is supplied to the motor 55 without going through the
It shows the relationship between rotational speed N and torque T, where the solid line in the figure shows the case where the governor circuit 67 is used, and the dotted line in the figure shows the case where the governor circuit 67 is not used.

Furthermore, after the operators 12 to 16 are operated,
During the so-called soft touch mechanism operation period until the operation slugs corresponding to the operated operators 12 to 16 are moved to the operation position, the means for supplying power to the motor 55 without going through the governor circuit 67 is as follows. It may be arranged as shown in FIG. In other words, both contact pieces 611 and 612 of the switch 61 that engage with the other end of the drive lever 59 are connected to both ends of the governor circuit 67, respectively. In this way, the cam gear 51 meshes with the gear 54, and the cam 513 causes the first
As shown in FIG. 5, when the drive lever 59 is rotated counterclockwise in the figure, both contact pieces 611 and 612 of the switch 61 come into contact and the governor circuit 67 is short-circuited.

Therefore, during the operating period of the soft touch mechanism, electric power is supplied to the motor 55 without going through the governor circuit 67, thereby increasing the rotational speed of the motor 55 and increasing the torque. can be performed quickly and in a short period of time.

Further, as shown in FIG. 14, a distance (l ₁ ) is provided between the center of the rotating shaft 50 of the flat portion 514 of the cam 513 and the right end in the figure. Therefore, when the cam gear 51 rotates in the direction of arrow G in the figure, when the cam 513 rotates the drive lever 59 counterclockwise in the figure, it first rotates largely and then rotates along the curve of the cam 513. This can contribute to the rotation of the drive lever 59 and, in turn, to the acceleration of the operation of the soft touch mechanism.

In addition, as shown in FIG. 16, the power switch 70 is turned on in conjunction with each operation slider to set the contact pieces 381, 382 of the switch 38 in a predetermined running state for the tape of the tape recorder mechanism. It may be connected to both ends respectively. In this way, for example, when the regeneration operation element 14 is operated, the gear lock lever 41 will lock the gear lock pin 415.
is rotated to a position where it is removed from the through hole 511 of the cam gear 51. At this time, both contact pieces 381 and 382 of the switch 38 are brought into contact via the protruding piece 416. Therefore, power is supplied to the motor 55,
The motor 55 is rotationally driven. Then, it is rotated by the rotational force of the cam gear 54, and the reproduction operation slider 44 is moved to the operation position as described above.
Therefore, in conjunction with the movement of the reproduction operation slider 44, the power switch 70 is turned on. and,
When the cam gear 51 rotates once, the gear lock pin 415 of the gear lock lever 41 is inserted into the through hole 511 of the cam gear 51, and both contact pieces 3 of the switch 38 are inserted.
81,382 will leave. However, since the power switch 70 is turned on at this time, power is supplied to the motor 55 and the tape is run while being played back.

Here, once the gear lock pin 415 is removed from the through hole 511 of the cam gear 51, the gear lock lever 41 holds both contact pieces of the switch 38 until the cam gear 51 rotates once and the gear lock pin 415 is inserted into the through hole 511 again. 381 and 382 are kept in contact with each other. Therefore, for example, even if the stop operator 11 is operated immediately after operating the regeneration operator 14, the gear lock pin 4
15 is removed from the through hole 511 of the cam gear 51, the switch 38 is turned on, and the gear 5
The cam gear 51 meshed with 4 rotates once and is reliably returned to its original position. Therefore, even if, for example, the stop operator 11 is operated immediately after the regeneration operator 14 is operated, the gear 54 and the cam gear 51 will not be stopped midway in meshing state, and the operation will be reliably performed. The cam gear 51 can be returned to its original state and can stand by for the next operation.

Also, the relationship between the state in which the gear lock pin 415 separates from the through hole 511 of the cam gear 51 and the corresponding operating state of the switch 38 will be explained. That is, as shown in FIG. 17a, the through hole 511 of the cam gear 51 is formed with a tapered portion 515 that widens from approximately the center of the thickness of the cam gear 51 in the direction in which the gear lock pin 415 comes out.
Here, when the gear lock pin 415 separates from the through hole 511 of the cam gear 51, as shown in FIG.
Both contact pieces 381 and 382 of No. 8 do not contact each other. Then, when the gear lock pin 415 reaches a position corresponding to the tapered portion 515 of the through hole 511, as shown in FIG. Press 415 to release gear lock lever 41
is moved in the direction of arrow I in the figure. At this time, both contact pieces 381 and 382 of the switch 38 are brought into sufficient contact so as to be pressed together.

Therefore, a switch 38 is connected in parallel to a power switch 70 that is turned on in conjunction with each operation slider to bring the tape into a predetermined running state, and a gear lock lever 41 that turns on and off this switch 38 is connected to a cam gear. Since the switch 38 is moved to be reliably turned on or off by the taper portion 515 of the switch 51, the operation elements 12 to 1
This can reliably eliminate the inconvenience that the gear 54 and the cam gear 51 are stopped midway while being engaged when the stop operation element 11 is operated immediately after the operation of the gear 54 and the cam gear 51.

Next, the protection slider 32 will be explained. That is, as shown in FIG. 18a, this protective slider 32 is connected to each operating member 24 to which the recording, rewinding, playback, and fast-forwarding controls 12 to 15 are attached.
The screws 33, 33 are inserted into long holes 321, 321 formed along the longitudinal direction at both ends of the holding plate 30, so as to be substantially orthogonal to the holding plate 30.
(See Fig. 3) and is supported so as to be slidable in the longitudinal direction. In addition, the protection slider 32
is urged rightward in the figure by a spring 71 being engaged between a through hole 322 formed at one end thereof and a pin 301 protruding from the holding plate 30 .

Here, pins 721 to 724 are provided protruding from each of the operating members 24 to 27, respectively.
The operating member 2 of the protective slider 32 is
At the end corresponding to the pin 721 of No. 4, there is a step that is positioned above the pin 721 in the figure with the protective slider 32 slid to the left in the figure, and prevents the operation member 24 from being operated in the direction of the arrow A. A portion 323 is formed. Further, an end of the protective slider 32 corresponding to the pin 724 of the operating member 27 is engaged with the pin 724, and when the operating member 27 is operated in the direction of arrow A, the protective slider 32 is slid to the left in the figure. A sloped portion 324 that can be tilted is formed.
Further, the operating member 25 of the protective slider 32,
Approximately square-shaped through holes 325 and 326 are formed in portions corresponding to the pins 722 and 723 of No. 26, respectively, and the pins 7
22 and 723 are loosely fitted. Here, the left end portions of the through holes 325 and 326 in the drawing are engaged with pins 722 and 723, respectively, and the protective slider 32 is moved in the left direction in the drawing with the operation members 25 and 26 being operated in the direction of arrow A. Slanted portions 327 and 328 that can be slid are formed respectively. Further, at the right end of the through hole 325 in the figure, a protective slider 32 is positioned above the pin 722 in the figure while being slid to the left in the figure, and prevents the operation member 25 from being operated in the direction of arrow A. Stepped portion 329
is formed.

If the playback operator 14 is now operated, the operating member 26 is slid in the direction of arrow A. Then, as shown in FIG.
26 to slide the protective slider 32 to the left in the figure. Therefore, the stepped portion 323 of the protective slider 32 is located above the pin 721 of the operating member 24 in the figure, and even if an attempt is made to operate the recording controller 12, the pin 721 of the operating member 24 is located above the stepped portion 323 of the protective slider 32. Abutted and made inoperable.

Furthermore, if the rewind operator 13 is operated with all of the operating members 24 to 27 in the non-operating position, the operating member 25 is slid in the direction of arrow A. Then, as shown in Figure 18b,
The pin 722 of the operating member 25 is moved to the position shown by the dotted line in the figure, and the pin 722 is moved to the position shown by the dotted line in the figure, and the pin 722
2, and slide the protective slider 32 to the left in the figure. Therefore, the stepped portion 323 of the protection slider 32
is located above the pin 721 of the operating member 24 in the figure, and the recording operator 12 is rendered inoperable.

Further, if the fast-forwarding operator 15 is operated with all the operating members 24 to 27 in the non-operating position, the operating member 27 is slid in the direction of arrow A. Then, as shown in FIG. 18c, the pin 724 of the operating member 27 presses the inclined portion 324 of the protection slider 32, causing the protection slider 32 to slide to the left in the figure. For this reason, the protection slider 3
The stepped portion 323 of No. 2 is located above the pin 721 of the operating member 24 in the figure, and the recording operator 12 is rendered inoperable.

That is, the rewind, play and fast forward controls 13
In a state where the recorder 15 is operated in advance, the recording operator 12 is rendered inoperable, thereby preventing so-called follow-up recording.

Further, as shown in FIG. 18c, the operating member 27
is in the operation position, the stepped portion 329 formed in the through hole 325 of the protection slider 32 is located above the pin 722 of the operation member 25 in the drawing. Therefore, even if an attempt is made to operate the rewind operator 13, the pin 722 of the operating member 25 comes into contact with the stepped portion 329 of the protection slider 32, making the operation impossible. Furthermore, as shown in FIG. 18b, when the operating member 25 is in the operating position, the pin 722 is at the position indicated by the dotted line in the figure, and the through hole 3 of the protective slider 32
It faces the right end of No. 25 in the figure. Therefore, the pin 724 of the operating member 27 is
Even if the user presses the inclined portion 324 of the protective slider 32 and tries to slide the protective slider 32 to the left in the figure, the pin 722 of the operating member 25 comes into contact with the right end of the through hole 325 of the protective slider 32 in the figure. Therefore, the protection slider 32 is not moved. Therefore, the fast-forward operator 15 is rendered inoperable.

That is, the rewind and fast forward operators 13, 15
are designed so that only one of them can be operated to prevent malfunctions.

In addition, when the operating member 26 is in the operating position, the pin 723 and the through hole 3 of the protective slider 32 are connected to each other.
Since there is a distance between the protection slider 32 and the right end of the slider 26 in the figure, the protection slider 32 can be further moved to the left in the figure from this position. Therefore, while the playback control 14 is being operated, the rewind or fast-forwarding controls 13 and 15 can be operated later, and there is no problem in performing review or cue operations. .

Therefore, by using a single protection slider 32, it is possible to prevent follow-up recording, rewind, and prevent both operations of the fast-forward controls 13 and 15, so the configuration is extremely simple, and the review and Kew can also be performed without any problems. Also, if rewind or fast forward operation buttons 13 and 15
If both are operated, the push levers corresponding to the rewind and fast forward operators 13 and 15 will both be moved to a position where they engage with the drive slider 62, and the drive slider 62 will not be able to rotate both push levers. Therefore, there is an inconvenience that a large load is applied to the motor 55. However, since both operations of the rewind and fast-forward operators 13 and 15 are prevented as described above, the drive slider 62 is configured to prevent the operation of either the rewind or fast-forward operators 13 and 15. child 13 or 15
All you have to do is turn the push lever that corresponds to
A large load is not applied to the motor 55.

Here, the pins 721 of each operating member 24 to 27
As shown in FIG. 3, cylindrical portions with a large diameter are formed on top of a cylindrical portion with a large diameter, and are provided as inserts in the operating members 24 to 27. Further, the operation members 23 and 28 to which the stop operation element 11 and the pause operation element 16 are attached
Similarly-shaped pins 725 and 726 are also provided respectively. The small-diameter cylindrical portion of the pin 726 of the operating member 28 to which the pose operator 16 is attached engages with a well-known push mechanism to cause the pose operator 16 to take a push-type operation mode. It's getting old. In addition, pins 721 to 724 of each operating member 24 to 27
The cylindrical portion having a large diameter is adapted to engage with the protective slider 32. Furthermore, the pin 725 of the operating member 23 to which the stop operator 11 is attached is
It doesn't interact with anything. That is, each of the operating members 23 to 28 is connected to the pins 725, 721 to 724, 7 in advance.
26, and the operating members 23 to 28 are mutually compatible.

Next, each of the operation members 24 to 27 to which the other operators 12 to 15, excluding the stop and pause operators 11 and 16, are attached is locked at the operating position, and each of the operation members 24 to 27 to which the other operators 12 to 15 are attached, excluding the stop and pause operators 11 and 16, is locked at the operating position, and each A locking mechanism for unlocking the operating members 24 to 27 at their operating positions will be described. That is, the 19th
As shown in FIG.
27, the operating elements 11 to 1 are slightly removed from their respective elongated holes 231 to 271 (see FIG. 3).
A lock slider 73 is provided at a portion closer to 5 so as to be substantially orthogonal thereto. This lock slider 7
3 is fixed in the longitudinal direction by inserting pins 302, 302 protruding from the holding plate 30 (see FIG. 3) into long holes 731, 731 formed along the longitudinal direction at both ends thereof. Supported in a slidable manner. Further, the lock slider 73 is rotated to the right in the figure by a spring 74 being engaged between a through hole 732 formed at one end thereof and a locking portion 303 provided on the holding plate 30. energized.

Here, lock pins 751 to 755 are formed on the operating members 23 to 27. The operating member 23 of the lock slider 73 is
A first inclined portion 733 is provided at a portion corresponding to the lock pin 751, which engages with the lock pin 51 when the operating member 23 is moved in the direction of arrow A in the figure, and can slide the lock slider 73 to the left in the figure.
Continuing with the first inclined part 733, a second inclined part 734 is formed in a substantially step-like shape and has a steeper inclination with respect to the lock pin 751 than the first inclined part 733. . Further, a portion of the lock slider 73 that corresponds to the lock pin 752 of the operating member 24 is engaged with the lock pin 752 while the operating member 24 is moved in the direction of arrow A in the figure, and the lock slider 73 is moved in the left direction in the figure. When the lock slider 73 is returned to the right in the figure by the biasing force of the spring 74 after the slope 735 and the lock pin 752 can be slid toward each other, the lock pin 752 contacts the lock pin 752 and the operating member 24 moves upward. A lock portion 736 is formed to prevent the device from returning in the direction of the middle arrow B.

Furthermore, the portion of the lock slider 73 that corresponds to the lock pin 754 of the operating member 26 has a
When the operating member 26 is moved in the direction of arrow A in the figure, it engages with the lock pin 754, and the lock slider 7
3 to the left in the figure.
When the lock pin 754 crosses the slope 737 and the lock slider 73 is returned to the right in the figure by the biasing force of the spring 74, it comes into contact with the lock pin 754 and the operating member 26 returns in the direction of arrow B in the figure. a first lock portion 738 that prevents
A second lock portion 739 is formed so as to slant upward continuously from the lock portion 738, and performs the same function as the first lock portion 738.

Also, the operating member 2 of the lock slider 73
The operating members 25 and 27 are respectively engaged with the lock pins 753 and 755 at the portions corresponding to the lock pins 735 and 755, respectively, while being moved in the direction of the arrow A in the figure, and the lock slider 73 is moved in the direction shown in the figure. First inclined parts 761, 762 that can be slid to the left and lock pins 753, 75
When the lock slider 73 is returned to the right in the figure by the biasing force of the spring 74, the lock pin 75
3,755 and the operating members 25, 27, respectively.
The lock portions 763 and 764 prevent the operation members 25 and 27 from returning in the direction of arrow B in the figure, and the lock pins 753 and 755 are engaged with the operating members 25 and 27, respectively, when the operation members 25 and 27 are further moved in the direction of arrow A in the figure. Second slanted portions 765 and 766 are formed, respectively, to allow the slider 73 to slide rightward in the figure.

If the rewind operator 13 is now operated alone, this operation moves the operating member 25 in the direction of arrow A in the figure. Then, the operating member 25
The lock pin 753 is the first lock pin 753 of the lock slider 73.
The lock slider 73 is slid to the left in the figure against the biasing force of the spring 74. Then, the lock pin 753 is
After crossing the slope 761, the lock slider 73
returns to the right in the figure again, and at this time lock pin 7
53 comes into contact with the lock portion 763, and the operating member 25 is locked in the operating position. When the stop operator 11 is operated in such a state, the operating member 23
The lock pin 751 presses the first inclined portion 733 and moves the lock slider 73 to the left in the figure. Therefore, the lock portion 763 is attached to the lock pin 75.
3, and the operating member 25 is returned in the direction of arrow B.

Further, when the fast forward operator 15 is operated, the locking and unlocking of the operating member 27 at the operating position can be explained in the same manner as the rewind operator 13.

Further, if the playback operator 14 is operated alone, the operation member 26 is moved in the direction of arrow A in the figure by this operation. Then, the lock pin 754 of the operating member 26 touches the inclined portion 7 of the lock slider 73.
37, the lock slider 73 is slid to the left in the figure against the biasing force of the spring 74. When the lock pin 754 passes over the slope 761, the lock slider 73 returns to the right in the figure again, as shown in FIG. is locked in the operating position. Furthermore, when the stop operator 11 is operated, the lock slider 73 slides to the left in the figure, and the first lock portion 738 disengages from the lock pin 754.
The operating member 26 is returned to its original position.

Note that when the recording operator 12 and the playback operator 14 are operated together, the playback operator 14 is locked at the operating position as described above, and the recording operator 12 is locked when the lock pin 752 of the operating member 24 hits the lock portion 736. It is designed to be locked in the operating position.

Here, as shown in FIG. 19b, when the playback operation element 14 is locked in the operation position, the lock pin 753 of the operation members 25, 27 to which the rewind and fast forward operation elements 13, 15 are attached, 755
The inclined portion 737, the first inclined portion 761, and
762, the slide stroke of the lock slider 73 to the left in the figure is defined. Therefore, if the fast forward operator 15 is operated while the tape recorder is in the queue state in the playback state, the operating member 27 is moved at once in the direction of the arrow A until the lock pin 755 abuts the second inclined portion 766. It is placed in a queue state. At this time, the lock pin 755 does not come into contact with the lock portion 764, so when the operation of the fast-forward operator 15 is stopped, the fast-forward operator 15 is returned to its original position, and the tape recorder returns to the playback state. In other words, the queue state occurs only while the fast-forward operator 15 is being operated.

Here, the fast forward operator 15 is moved to the operating member 2.
Suppose that the lock pin 755 of No. 7 is in contact with the second inclined portion 766 and is further pressed in the direction of arrow A in the figure. Then, the lock pin 755 presses the second inclined portion 766, causing the lock slider 73 to slide rightward in the figure. Therefore, the lock pin 754 of the operating member 26 is tilted from the first lock part 738 onto the second lock part 739, as shown in FIG. 19c. At this time, the lock portion 764 of the lock slider 73 is
The position is opposite to the lock pin 755 of the operation member 27, and even when the fast-forward operation element 15 is stopped,
The lock pin 755 is locked into the lock portion 764 as shown by the dotted line in the figure, so that the queue state is continued.

Therefore, when the fast-forward operator 15 is operated in the playback state, the lock pin 754 of the operating member 26 is moved from the first lock portion 738 to the second lock portion 739.
By applying the load of causing the fast-forwarding operator 15 to ride on the operator, it is possible to give a click feeling to the operator, thereby allowing the operator to decide whether or not to lock the fast-forward operator 15 at the operating position.

Furthermore, even when the rewind operator 13 is operated while the tape recorder is in the playback state and the tape recorder is not in the review state, a similar click feeling can be given to the operator, and the lock position of the rewind operator 13 can be determined. It is something that can be done.

Here, the tape recorder detects an unrecorded part between songs on the tape, and the detection signal moves the lock slider 73 from the state where the lock pin 754 of the operating member 26 is locked to the second lock portion 739 to the first position. If a mechanism is provided that allows the fast-forward operator 15 to slide slightly to the left in FIG. When the detection signal of the recording part is output,
The lock slider 73 is moved as shown in FIG. 19b, and the fast-forward operator 15 is unlocked from its operating position. Therefore, at the time when the detection signal is output, the tape recorder enters the playback state, and the first cue is found at this point.

Next, as shown in FIG.
8 may be used to mute the reproduced signal from the recording/reproducing head 77 during the operation of the soft touch mechanism. That is, the reproduced signal from the recording/reproducing head 77 is normally supplied to a speaker, an external output jack, etc. (not shown) via the equalizer amplifier 78, the amplifier 79, the resistor _R1 , and the output terminal 80. Amplifier 79 for piece 381
By connecting the switch 38 to the connection point between the switch 38 and the resistor R ₁ and grounding the contact piece 382, when the switch 38 is turned on, the playback signal from the recording/playback head 77 is transferred to the switch 38.
The signal is bypassed to the ground side through the circuit and is not supplied to the output terminal 80, allowing muting to be performed.

The reason why the reproduced signal from the recording/reproducing head 77 is muted during the operation of the soft touch mechanism will now be explained. For example, when the playback operation element 14 is operated with the tape running stopped, the gear lock pin 415 of the gear lock lever 41 is disengaged from the through hole 511 of the cam gear 51, and the playback operation slider 44 is then moved to a predetermined position via the drive slider 62 and push lever 45. will be moved to Then, until the reproducing operation slider 44 reaches a predetermined position, the recording/reproducing head 77 comes into contact with the tape and the tape continues to run.
At this time, the motor 55 is connected to the playback operation slider 4.
In order to move the flywheel 5, a larger load is applied than during normal tape running, and the flywheel 5
2's wah is getting louder. For this reason, when the recording/playback head 77 contacts the tape and starts running the tape as described above while the flywheel 52 has a large wow, the reproduced signal becomes very inaudible when converted into audio. Become young. and,
In this state, the cam gear 51 rotates once and the motor 55
This continues until the load on the soft touch mechanism is reduced, that is, during the operating period of the soft touch mechanism. Therefore, after the gear lock pin 415 of the gear lock lever 41 separates from the through hole 511 of the cam gear 51, the cam gear 51
By turning on the switch 38 and muting the playback signal until the player rotates once, it is possible to avoid outputting a playback signal with a large wah effect at the start of playback.

Further, the adverse effect on the playback signal due to the increase in wow of the flywheel 52 during the operation of the soft touch mechanism is not limited to the case where the playback operator 14 is operated as described above. , 15 or the pause operator 16, in other words, when the recording/playback head 77 is brought into contact with or separated from the tape,
This occurs when the contact state is transferred to another state. However, since the switch 38 is turned on and muting is performed when changing the mode of such a tape recorder, it is possible to prevent reproduction output due to an increase in wah.

Furthermore, as a means for applying muting during the operating period of the soft touch mechanism, as shown in _FIG . 612 may be grounded. By doing this, the switch 61 is turned on when the cam 513 of the cam gear 51 is rotating the drive lever 59, as shown in FIG. This will lead to mutating.

Moreover, although the above description has been made regarding muting of a reproduced signal, this can be similarly performed with regard to muting of a recorded signal. That is, although not shown in FIGS. 20 to 22, the recording/reproducing head 77 is supplied with signal from an external microphone or the like via a recording amplifier.
By interposing the switch 38 or 61 in the path where the recording signal is supplied to the recording/playback head 77, the recording signal is muted during the operation of the soft touch mechanism, and recording is performed while the flywheel 52 has a large wah effect. It is possible to prevent this from happening.

Here, as previously explained in FIGS. 12 to 15, during the operation period of the soft touch mechanism, the switch 38 or 61 is used to supply power to the motor 55 without going through the governor circuit 67, so that the operation can be started quickly. There is a mechanism to make it happen. FIGS. 23 and 24 show a modification based on such a mechanism. First, in the switch shown in FIG. 23, the contact piece 611 of the switch 61 is connected to one end of the governor circuit 67, and the contact piece 612 is connected to the contact piece 811 of another switch 81. Connect the contact piece 812 to the other end of the governor circuit 67. Both contact pieces 811, 812 of this switch 81 are plate-shaped with elasticity, and usually both contact pieces 811, 812
are spaced apart. Both contact pieces 811 and 812 of the switch 81 are then manually operated on the tape recorder.
A button 82 is provided for contacting the button 82.

With this configuration, if the tape recorder is now driven by battery power, the power terminals 68 and 69
will be supplied with battery power. and,
Normally, the contact pieces 811 and 812 of the switch 81 are separated from each other, so battery power is supplied to the motor 55 via the governor circuit 67 regardless of whether the switch 61 is on or off. That is, in the configuration shown in FIG. 23, battery power is supplied to the motor 55 via the governor circuit 67 even during the operation period of the soft touch mechanism.

Then, the battery power gradually becomes exhausted, and when the cam gear 51 rotates to the position shown in FIG.
Suppose that the rotation of has stopped. At this time, both contact pieces 811 and 8 of the switch 81 are operated by operating the button 82.
12, both ends of the governor circuit 67 are short-circuited via the switches 61 and 81, and the motor 55 is directly supplied with battery power. Therefore, a higher battery voltage is applied to the motor 55 by the amount that has been lowered by the governor circuit 67, and the motor 55 rotates again, causing the cam gear 5 to rotate.
1 is rotated to its original position.

Therefore, when the rotation of the motor 55 stops due to consumption of battery power while the soft touch mechanism is operating, the governor circuit 67 is removed and battery power is directly supplied to the motor 55 to rotate the motor 55. It is possible to prevent the cam gear 51 from stopping while still meshing with the gear 54,
The cam gear 51 can always be returned to its original position. For example, if the motor 55 stops rotating when the playback operator 14 is operated and the cam gear 51 is in the state shown in FIG. Since the tape is stuck inside the tape cassette, it becomes impossible to remove the tape cassette. In addition, the stop operation element 11 is provided with an eject operation,
A tape having a so-called double-action eject function in which when the stop operator 11 is operated once, the other operators 12 to 15 are returned to their original positions, and when the stop operator 11 is operated for the second time, an eject operation is performed. In the case of a recorder, even if the rewind and fast forward operators 13 and 15 are operated to reach the state shown in FIG. 23, there is a problem in that the eject cannot be performed.

However, when the motor 55 stops, the governor circuit 6
By removing 7, the cam gear 51 can be returned to its original position and the tape cassette can be taken out. Further, as described above, even when the soft touch mechanism is operating, battery power is supplied to the motor 55 through the governor circuit 67, and when the rotation of the motor 55 stops due to consumption of battery power with the cam gear 51 rotating halfway, Since battery power is directly supplied to the motor 55 without going through the governor circuit 67, the user can also determine when it is time to replace the battery.

Next, in the one shown in FIG. 24, the contact piece 611 of the switch 61 is connected to _the movable contact piece _S11 of the changeover switch S1. The first fixed contact piece _S12 of this changeover switch _S1 is connected to one power supply end of the motor 55, and is also connected to the _second fixed contact piece _S23 of the other changeover switch S2. Further, the second fixed contact piece _S13 of the changeover switch _S1 is connected to the other power supply terminal of the motor 55, and is also connected to the first fixed _contact piece _S22 of the changeover switch S2. and,
The movable contact piece S ₂₁ of the changeover switch S ₂ is connected to the power supply terminal 68, and the contact piece 612 of the switch 61 is connected to the power supply terminal 69.

Here, each movable contact piece of the above changeover switches S ₁ and S ₂
S ₁₁ and S ₂₁ are elastic plates, and are usually in contact with the respective second fixed contact pieces S ₁₃ and S ₂₃ . By operating a manually operable button 83 provided on the tape recorder, these changeover switches S ₁ and S ₂ simultaneously change the movable contact pieces S ₁₁ and S ₂₁ to the first fixed contact pieces S ₁₂ and S ₂₂ .

Here, the battery power is now exhausted and the cam gear 513
Suppose that the rotational speed becomes extremely slow at the position shown in FIG. At this time, when the button 83 is operated, the polarity of the battery voltage applied to the motor 55 is reversed, and the motor 55 rotates in the opposite direction. Therefore, the cam gear 51 is also rotated in the opposite direction, that is, counterclockwise in the figure.
Due to the shape of the curved portion 13 and the biasing of the drive lever 59 clockwise in the figure, the cam gear 5
1, the load is smaller when rotating counterclockwise in the figure. Therefore, the load on the motor 55 can be reduced.
The cam gear 51 can be returned to its original position when battery power is exhausted.

In addition, as a protective measure when the cam gear 51 stops in mesh with the gear 54 due to battery power consumption during operation of the soft touch mechanism, see Fig. 25a.
This may be done as shown in . That is, the cam gear 51 is slidable in the axial direction with respect to the rotating shaft 50, and the cam gear 51 is normally biased to the left in the figure by the spring 84. The cam gear 51 is biased leftward in the figure, and its cam 513 engages with the drive lever 59. The tape recorder is also provided with a release lever 85 that can be manually operated from the outside and slides the cam gear 51 to the right in the figure against the biasing force of the spring 84 to separate the cam 513 from the drive lever 59. There is. This release lever 85 is approximately L-shaped, and its corner portion is rotatably supported by a shaft 851 within the tape recorder. One end of the release lever 85 engages with the cam gear 51, and the other end protrudes outward from the tape recorder housing to which an operator 852 is attached. Further, the release lever 85 is biased counterclockwise in the figure by a spring 853 that is engaged between the other end and the tape recorder housing.

Now, the operator 1 that makes the tape run
2 to 15 are operated, and the cam gear 51 changes to the gear 54.
The cam 513 engages with the drive lever 59 and rotates.
Suppose that the rotation of the motor 55 stops due to consumption of battery power while the button is being pressed. At this time, as shown in FIG. 25b, the operator 852 is operated to rotate the release lever 85 clockwise in the figure against the urging force of the spring 853. Then, one end of the release lever 85 comes into contact with the cam gear 51, and the cam gear 51 is slid to the right in the figure against the biasing force of the spring 84. For this reason, the cam 51
3 is removed from the drive lever 59. At this time, the load on the motor 55 is lightened, so it rotates even though the electric power is consumed and moves the cam gear 51 into its notch 51.
2 and rotate it to a position facing the gear 54.
At the same time, the drive lever 59 is returned to its original position by the drive slider 62 being urged upward in FIG. 6, and protection is provided here when the battery power is exhausted.

Next, the automatic stop mechanism of the tape recorder will be explained. That is, in FIG. 26, 86 is one of the pair of reel stands. This reel stand 86 is provided with a friction plate 87 coaxially rotatable with the reel stand 86 with a predetermined frictional force and having a pair of substantially wing-shaped engaging portions 871 and 872. Further, both engaging portions 8 of the friction plate 87
71 and 872, there is located a first arm portion 881 of a tape stop detection lever 88, which has a substantially cross shape and whose intersection point is rotatably supported by a shaft 491 provided on the main chassis 49 of the tape recorder. ing. The shaft 491 is connected to the ASO lever 8.
A long hole 89 is formed in one end of 9 in the longitudinal direction.
1 to rotatably support the ASO lever 89. This ASO lever 89 has a spring 90 engaged between a through hole 892 formed in the approximate center thereof and a through hole 883 formed in the second arm portion 882 of the tape stop detection lever 88. As a result, it is interlocked with the tape stop detection lever 88.

The other end of the ASO lever 89 extends to the vicinity of an idler 92 that is provided coaxially with the flywheel 52 and is engaged with a pulley 91 that rotates together with the flywheel 52 so as to transmit rotational force. A pin 893 is implanted in the portion.
The idler 92 has a substantially cylindrical shape with a bottom, and a substantially cylindrical cam portion 922 is provided therein so as to be slightly eccentric with respect to the rotating shaft 921 of the idler 92. Then, the above-mentioned
The pin 893 of the ASO lever 89 is loosely fitted. Further, on the inner wall surface 923 of the idler 92, a flywheel 52 rotates in the direction of the arrow H in the figure at a portion farthest from the cam part 922, thereby causing the idler 92 to rotate in the direction of the arrow I in the figure. An engaging portion 925 is formed that engages with a pin 893 of the ASO lever 89 in a rotated state to move the ASO lever 89 downward in the figure against the biasing force of the spring 90.

When the ASO lever 89 is moved downward in the figure, the lock slider 73 shown in FIG. 19 is slid to the left in FIG. , rewind, play and fast forward controls 12 to 1
5 are each unlocked and returned to the non-operating position.

Further, in the vicinity of the third arm portion 884 of the tape stop detection lever 88, an engaging arm 93 protrudes from one end of an ASO bias lever 93 that is rotatably supported on the main chassis 49 about a shaft 492.
1 is located. This ASO bias lever 9
3, an extending portion 932 protruding from the other end;
A spring 94 is engaged between the main chassis 49 and a locking portion 493, so that the main chassis 49 is biased counterclockwise in the figure. and,
The rotation of the ASO bias lever 93 in the counterclockwise direction in the figure is caused by the engagement part 9 provided at the lower end in the figure.
33 reaches a position where it abuts against the top 625 of the drive slider 62.

Here, assuming that the tape is currently running in a predetermined state, either the engaging portion 871 or 872 of the friction plate 87 will move to the first position of the tape stop detection lever 88 depending on the tape running direction, that is, the rotating direction of the reel stand 86. 1 and rotates the tape stop detection lever 88 clockwise in the figure. As a result, the ASO lever 89 also rotates in the same direction, and its pin 893 comes into contact with the circumferential side of the cam portion 922 of the idler 92. Therefore, even if the idler 92 rotates, the pin 893 only traces the circumferential side of the cam portion 922 and does not engage with the engaging portion 925, so that stable tape running is performed.

Suppose, for example, that the tape reaches the end in such a tape running state and the tape running is stopped. Then, the rotation of the reel stand 86 is stopped, so the tape stop detection lever 88 and the ASO lever 89 are no longer subjected to biasing force. At this time, the flywheel 52 continues to rotate, and the idler 92 also
rotating in the direction. For this reason, ASO lever 8
9, the pin 893 is connected to the cam part 9 of the idler 92.
22 to the position closest to the inner wall surface 923, it no longer traces the circumferential side of the cam portion 922 and remains close to the inner wall surface 923. Therefore, the engaging portion 92 is attached to the pin 893.
5 is struck, the ASO lever 89 is moved downward in the figure, and is automatically stopped at this point.

For example, suppose that the rewind operator 13 is operated while the tape is being played and the review operation is not performed. Then, in conjunction with the operation of the rewind operator 13, the drive slider 62 moves downward in the figure as shown in FIG.
Leave from 3. Therefore, the ASO bias lever 93 is rotated counterclockwise in the figure by the biasing force of the spring 94. At this time, the engaging arm 931 of the ASO bias lever 93 contacts the third arm portion 884 of the tape stop detection lever 88, causing the tape stop detection lever 88 to rotate clockwise in the figure. For this reason, pin 893 of ASO lever 89
is forcibly pressed toward the circumferential side of the cam portion 922 of the idler 92.

When the drive slider 62 is returned to the position shown in FIG. 26, the tape is running in the review state, so the tape stop detection lever 88
is biased clockwise in the figure via the friction plate 87, so the pin 893 of the ASO lever 89 also pushes against the cam portion 9.
The state in which it is in contact with the 22nd circumference side is maintained.

Therefore, while the drive slider 62 reciprocates, the ASO bias lever 93 causes the pin 893 of the ASO lever 89 to engage the engaging portion 925 of the idler 92.
Since the cam part 922 is forcibly pressed against the circumferential side so as not to engage with the cam part 922, even if the tape running stops once when changing from the playback state to the review state, automatic stop is not performed. Can be done. That is, when switching from the regeneration state to the review state, the switching does not occur instantaneously, but until the cam gear 51 rotates, that is, the drive slider 62
It is necessary to wait until the tape has made one reciprocation, and it is possible to prevent the automatic stop from being erroneously performed due to the tape running being stopped during this time.

Furthermore, this can be similarly explained not only when transitioning from the playback state to the review state, but also when transitioning from the playback state to the queue state. However, especially when transitioning from the playback state to the review state, since the tape running direction is reversed, the tape running must necessarily be temporarily stopped, so this is particularly effective in this case.

Furthermore, the mechanism for preventing automatic stop during the operation of this soft touch operation mechanism is such that when the tape recorder is changed from the playback state to the queue or review state, the rewind and fast forward operation buttons 13 , 15 are locked in their operating positions, that is, when they are set to the one-shot cue state, the same effect is achieved. In other words, when the tape recorder is in the playback state, it can be automatically stopped whether the rewind or fast forward operators 13, 15 are locked at the operating position or not.

Next, the cam gear 51, drive lever 59, drive slider 62, etc. may be supported by a support plate 95 that supports the flywheel 52 instead of the main chassis 49, as shown in FIGS. 28 to 30. . That is, flywheel 5
As is clear from FIG. 29, 2 is rotatably supported by being interposed between the main chassis 49 and a support plate 95 disposed approximately parallel to the main chassis 49, so that it does not have the structure of a normal tape recorder. be. Therefore, by using the support plate 95 not only to support the flywheel 52 but also to support the cam gear 51, the drive lever 59, the drive slider 62, etc. that constitute the soft touch mechanism, the tape can be placed on the main chassis 49. Since only the recorder mechanism needs to be constructed, the construction is extremely simple and manufacturing is easy. In addition, the support plate 9
5 is replaced with one that supports the cam gear 51, drive lever 59, drive slider 62, etc., and there is no need to modify the mechanism on the main chassis 49. Therefore, a soft touch mechanism can be easily added to a conventional tape recorder. It is possible.

Note that this invention is not limited to the above-mentioned embodiments, and can be implemented with various modifications without departing from the gist thereof.

Therefore, as detailed above, according to this invention, when performing a so-called follow-up operation in which one of the operators of a tape recorder is operated in advance and another operator is operated, the soft touch is used. It is possible to provide an extremely good soft touch operation mechanism for a tape recorder that does not apply unnecessary load to the motor that is the drive source of the operation mechanism.
