The present invention is a reciprocating movement freely installed and can be surely switched the operation mode of the tape recorder in relation to the selective operation of the rewinding control member and the fast-moving control member, all switching devices of the tape recorder of easy configuration with excellent operability It is about.

The on-vehicle tape recorder automatically sets the playback mode in conjunction with the loading of the tape cassette as disclosed in, for example, Utility Model Publication No. 87-13870 (Japan: Japanese Patent Application Laid-Open No. 62-138330), and the tape in a predetermined direction. It is configured to operate by driving at a constant speed. In addition, the selective feeding operation of the fast-feeding operation member and the rewinding operation member provided with the reciprocating motion freely causes the operation member to be caught in the king-operating position, so that the speed-feeding mode or the rewinding mode can be set, and the forward direction (regeneration direction) or The tape is fed at high speed in the reverse direction.

Specifically, the rewinding operation member and the fast-feeding operation member are installed in parallel with each other and inward reciprocatingly freely from the front side of the tape recorder so that the rewinding operation member and the fast-feeding operation member can be pushed in the double direction (forward) by the return spring. It is. Then, when the speed feed operation member is selectively operated in the throttle operation, the speed transfer control member is caught in the throttle operation position, the speed transfer mode is set, and the tape is driven at the high speed in the regeneration direction. When the rewinding operation member is operated by the rewinding operation, the rewinding operation member is held at the retracting position, the rewinding mode is set, and the tape traveling direction is reversed to drive the tape at high speed.

The release of the fastening mode or the rewinding mode set in this way causes the other operation member in the double operation position to move to a predetermined position (locking release position). By releasing and returning the operation member to the double-operation position to return to the original regeneration mode.

By the way, when canceling the speed transfer mode or the rewinding mode in this way, there is a possibility that the operation member may sometimes be operated to the position beyond the release position. In this case, for example, the rewinding operation member operated by the throttled operation that needs to be released from the throttled transfer mode is caught in the king operating position in place of the throttled transfer control member. Will be fulfilled.

As described above, in the conventional tape recorder, when one operation member is locked to the moving position, the rewind mode or the fast transfer mode set is canceled, and the operation returns to the original playback mode. The operation member may be moved more deeply than necessary.

In this case, the original regeneration mode is not set, and the speed feed mode and the rewind mode are set again. In order to prevent such a defect, it is necessary to add or subtract the kinetic operation amount (the pushing amount) of an operation member by hand, and operability fell.

The present invention has been made in view of the above circumstances, and its object is to perform the switching setting of the operation mode without adding or subtracting the manual operation of the rewinding operation member and the rapid transfer operation member by hand, and further improving its operability. The present invention provides a tape recorder mode switching device.

The mode for switching the tape recorder according to the present invention is provided with a rewinding operation member and a fast-feeding operation member which are parallel to each other and are provided freely for reciprocating operation, and set the regeneration mode when these operation members are in the mutually operating position. When one of the operation members has been moved in an alternative manner, the operation member is caught in the operation position of the tape to set the rewinding mode or the fast transfer mode of the tape, and at the same time, the other operation member is predetermined. When the operation is performed up to the position, the mode is switched by releasing the latch at the operation position of the one operation member and returning to the original regeneration mode, whereby the rewind operation member or the rapid transfer operation member is Alternatively, located in the reciprocating motion path and operated to a predetermined position for releasing the rewind mode or the rapid transfer mode. The amount of movement of the rewinding operation member and the speedy transfer operation member at the engaging position to the latching position is provided to the rewinding operation member and the speedy transfer operation member at the same time as providing a movement amount restrictor which abuts the contact portion of the ash to prevent further operation of the operation member. It is characterized in that a push-back portion is provided in contact with the regulator to position this movement amount regulator in the reciprocating motion path of the other operation member.

According to the present invention configured as described above, the fast-feeding operation member or the rewinding operation member may be selectively moved to the king-operated position so that the fast-feeding mode or the rewinding mode is set in the fast-feeding mode or the rewinding mode. Predetermined position (disengagement release position) for releasing the rewinding mode or the speeding mode of the other operation member by the movement amount restrictor which is displaced against the pressing retreat of the member and positioned in the reciprocating motion path of the other operation member. Over movement is blocked. Therefore, when the rewind mode (fast feed mode) is released, the operation member does not move more than necessary, so that the uneven speed feed mode (rewind mode) is not set. Can be set. In addition, since the moving amount of the operation member is regulated by the moving amount regulation member, it is not necessary to add or subtract the operation of the operation member by hand, thereby making it possible to improve its operability.

Hereinafter, a mode switching apparatus of a tape recorder according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view showing an overall schematic configuration of an on-vehicle tape recorder, and FIG. 2 is a side view in the direction of arrow II in FIG. First, a schematic configuration of a tape recorder will be described with reference to these drawings.

The tape cassette 10 is inserted into a cassette holder not shown in the arrow C direction orthogonal to the reciprocating direction of the head mounting plate 2, and the reel hub is reeled by moving the cassette holder to the regeneration operation position. Fit to (8, 9), it is loaded in the tape recorder. In conjunction with the mounting of the tape cassette 10, the head mounting plate 2 is moved (forwarded) in the direction of the arrow A, and both capstan shafts 4, 5 and one of the reel receivers 8, 9 Each is driven by rotation. At the same time, the pinch rollers 6, 7 on the same side are connected to the corresponding capstan shafts 4, 5 by pressing. As a result, the tape is driven at constant speed in one direction, and a reproducing mode in which the recording information of the tape is reproduced by the magnetic head 3 is set.

By the way, in the upper position of the magnetic head 3, the plate-shaped rewinding operation member 11 and the speed feed which are provided on the left end side (operation panel side) in the figure, respectively, are provided with a rewind button 11a and a speed transfer button 12a. As described below, the operation member 12 is disposed freely reciprocally in the state of being polymerized with each other and in the directions of arrows C and D.

That is, studs 13 and 14 are placed upright, respectively, as shown in FIG. 1 and FIG. 2 at positions next to the receiving space of the tape cassette 10 on the substrate 1. On the upper end of the stud 13, a guide plate 15 on which the rewinding operation member 11 and the fast-moving operation member 12 are mounted is fixed in parallel with the substrate 1.

As shown in the exploded perspective view of FIG. 3, the guide plate 15 is provided with a first guide hole 17 in a bent portion 16 formed by bending upwardly at one end thereof, and at the other end thereof in FIG. As shown in FIG. 3, the curved second guide hole 18 is provided. Moreover, as shown in FIG. 2 and FIG. 3, the bending piece 19 comprised by bending upward of the other end part side of this guide plate 15 is formed with the guide groove 20 of the said shape. The rewinding operation member 11 with respect to the guide plate 15 inserts the operation shortened portion into the guide hole 17 and fits one side portion into the guide groove 20, and the engaging groove of the tip portion thereof ( 21) is mounted freely reciprocating in the direction of the image cloth C, D in a state where it is engaged with the upper end of the other stud 14.

In addition, as shown in FIGS. 1 and 3, the rewinding operation member 11 is provided with a cam hole 22 in the center portion, and a pressing portion 23 protruding upwardly on one side of the tip portion. The pressing piece 24 is provided in the other side lower part of a front end part, and the spring receiving piece 25 is provided in the vicinity of the said cam hole 22. Moreover, as shown in FIG. The cam hole 22 has a circular arc portion with the same shape as the second guide hole 18 and is larger than the guide hole 18. Then, the rewinding operation member 11 is integrated on the guide plate 15 by joining the circular arc portion of the cam hole 22 with the circular arc portion of the second guide hole 18 to mount the spring receiving piece 25 and the guide plate. By the elastic bearing force of the tension spring 26 provided between the bent part 16 of (15), the double-direction direction (arrow D direction) is always supported.

In addition, as shown in FIG. 3, the fast-feeding operation member 12 has a cam hole 27 which is polymerized with the cam hole 22 of the rewinding operation member 11 at the center thereof. The spring receiving piece 28 is provided in the vicinity of 27, and the engaging groove 29 and the pressing part 30 are provided in the front-end | tip part, respectively. The fast-feeding operation member 12 inserts the engaging piece 31 adjacent to the operation end into the first guide hole 17 and at the same time inserts one side portion into the guide groove 20 and the front end portion thereof. The engaging groove 29 is polymerized on the upper side of the rewinding operation member 11 while being engaged with the upper end of the stud 14 so that the guide groove 15 is freely reciprocated in the direction of arrows C and D on the guide plate 15. . The fast-feeding operation member 12 is always in the double-direction direction (arrow) by the elastic bearing force of the tension spring 32 which is constructed between the spring receiving piece 28 and the bent portion 16 of the guide plate 15. C, D direction).

On the other hand, the tape running direction switching member 33 is mounted on the top of the stud 14 overlapping the speed transfer control member 12. The tape traveling direction switching member 33 is capable of reciprocating in the same direction as both of the operation members 11 and 12 by fitting the long hole 34 provided thereon to the upper end of the stud 14, and the stud ( 14) It is free to rotate around the center. As shown in FIG. 4, the tape travel direction switching member 33 is positioned at both front edges of the long holes 34 in front of the pressing portions 24 and 30 of the operation members 11 and 12, respectively. It has the shape which made into inclined surfaces 35 and 36, and made the front end into the arc surface 37. As shown in FIG. The operation force transmission member 44 which will be described later is disposed at the position opposite to the arc surface 37 so as to face the pressed portion 53.

In this way, the tape traveling direction switching member 33 is pressed by the pressing portion (11) of the operating member 11 when the rewinding operation member 11 moves in the arrow C direction by the pressing operation of the rewinding button 11a. 23, the inclined surface 36 on the right side is pushed and rotates counterclockwise as shown in FIG. In addition, when the speed control operation member 12 moves in the direction of the arrow due to the gambling operation of the speed control button 12a, the inclined surface 35 on the left side is pressed by the pressing part 30 of the operation member 12. It rotates clockwise as shown in FIG.

In addition, when both of the operation members 11 and 12 simultaneously move in the direction of arrow C by simultaneously pressing the rewinding button 11a and the governing movement button 12a, the tape traveling direction switching member 33 operates both. Each inclined surface (35, 36) is pressed simultaneously by the pressing portions (23, 30) of the members (11, 12), as shown in Figure 7, both of the operating member (11, 12) move in the direction of arrow C. At this time, the movement amount of the tape running direction switching member 33 is limited by the fitting relationship between the long hole 34 and the stud 14, and at the same time, the angle of the tape running direction switching member 33 is restricted by the restriction of the movement amount of the tape running direction switching member 33. The amount of tumbling of the operating members 11 and 12 is also regulated. In this simultaneous pressing, the regulating operation amount of the two operating members 11 and 12 is defined as [direction change amount] in this embodiment.

In addition, when the tape running direction switching member 33 moves in the direction indicated by the arrow C to the regulated position in this manner, the operation force transmission member 44 is prevented by the arc surface 37 of the tape running direction switching member 33. It functions by pressing the pressing part 53. As described later, the autoreverse mechanism (not shown) is started by the rotational movement of the operating force transmission member 44 to switch the running direction of the tape.

In the second guide hole 18 of the guide plate 15 and the cam holes 22 and 27 of the respective operation members 11 and 12, as shown in FIGS. At the tip of the head (39), a cam roller (38) freely supported by rotation is inserted. This rotary motion arm 39 is rotatably supported on the shaft 41 on which the substrate 1 is set up together with the pinch roller arm 40 which freely supports the pinch roller 6 on the left side described above. And the latching hole 42 which continued in the horizontal direction of the rotary motion arm 39 is arrange | positioned opposingly from the inner side to the cut piece 43 which protruded upwards to the head mounting plate 2. As shown in FIG.

In this way, when the speed control operation member 12 is moved beyond the above-mentioned [direction change amount], the cam roller 38 causes the cam hole 27 of the speed control operation member 12 as shown in Figs. 8A and 8B. The rotary motion arm 39 is rotated by being pushed by the cam surface 27a of the < RTI ID = 0.0 >) < / RTI > according to the guide hole 18 of the guide plate 15. By the rotational movement of the rotary motion arm 39, the cut pieces 43 of the head mounting plate 2 are pressed by the locking holes 42 of the rotary motion arm 39, and the head mounting plate 2 is A double operation (retraction) is performed in the direction of arrow B at the playback position.

Similarly, as shown in Figs. 9A and 9B, when the rewinding operation member 11 is operated over the above-mentioned [direction change amount], the cam roller 38 of the rewinding operation member 11 has a cam hole ( It is pushed by the cam surface 22a of 22, and is rotated along the guide hole 18 of the guide plate 15, and the rotary motion arm 39 rotates similarly. By the rotational movement of the rotary motion arm 39, the locking piece 42 of the rotary motion arm 39 is cut off, and the head mounting plate 2 is restored in the direction of arrow B from the regeneration position. It works.

Thus, in this embodiment, the actuation force of each of the operation members 11 and 12 required to rotate the rotary motion arm 39 and return the head mounting plate 2 to the regenerating position is referred to as [head pressing]. Return amount].

In addition, when both the tissue members 11 and 12 simultaneously operate in the direction of arrow C at the same time, as described above, the operation amount of the operation members 11 and 12 is less than the above [head press return amount]. Regulated by [turning direction]. Therefore, in this case, since the rotary motion arm 30 is not rotated by the operation members 11 and 12, the head mounting plate is not pressed back in the direction of arrow B.

By the way, in the vicinity of the tape traveling direction switching member 33 mentioned above, as shown in FIG. 10, the locking mechanism 32 and the operating force transmission member 44 are provided.

The locking mechanism 43 is a torsion member 46 which is freely propelled in rotational motion to a fixed shaft 45 mounted on the substrate 1, and a torsion for holding the locking member 46 in a counterclockwise direction in the drawing. It consists of the spring 47. A part of the locking member 46 is slidably connected to each of the operation members 11 and 12 along the side edge of the front end portion thereof, and the following exit portion 46a is provided with both of the operation members 11 and 12. The catching holes 50 for selectively catching the catching portions 48 and 49 formed at the tip are formed, respectively.

The locking member 46 is an operation member 11 which is in sliding contact with the following portion 46a when each of the operation members 11 and 12 moves in the direction of the arrow C beyond the above-mentioned [head pressing amount]. 12 is pressed by the locking portions 48 and 49, and rotates clockwise in response to the elastic bearing force of the torsion spring 47. Then, when the operation members 11 and 12 move in the direction of arrow C again, the locking member 46 is locked to the locking hole 50 as shown in FIGS. 10 and 11a, respectively. And 49 are rotated by the elastic bearing force of the torsion spring 47 to engage the operating members 11 and 12, and the operating members 11 and 12 are held at the corresponding royal operating positions.

Incidentally, the holding of the operation members 11 and 12 in the reciprocating operation position is alternatively performed. When the rewinding operation member 11 is held at the king operating position, the rewind mode is set in conjunction with this. When the speedy transfer control member 12 is held at the king operation position, the rewind mode is linked with this. Is set.

In this way, the operation | movement amount of the operation member which requires each operation member 11 and 12 to be locked to the operation | movement operation position by the locking member 46 is defined here as [mode setting amount] larger than the above-mentioned each movement amount.

If the rewinding operation member 11 is held by the locking mechanism 43 and the rewind mode is set to the predetermined position while the rewind mode is set, the interlocking operation member 12 is engaged. Sliding contact with the ear out portion 46a of the locking member 46 of the fitting portion 12 to rotate the locking member 46 in a clockwise direction. The locking movement of the rewinding operation member 11 by the locking member 46 is released by the rotational movement of the locking member 46 in the clockwise direction, and the rewinding operation member 11 of the tension spring 26 is removed. It is doubled by force. By returning the rewinding operation member 11 to the rewinding position, the rewinding mode is switched from the rewinding mode to the original regeneration mode. Similarly, the switching from the speed transfer mode to the regeneration mode is performed by releasing the rewinding operation member 11 to the predetermined position, thereby releasing the engagement of the speed transfer operation member 12 at the current operation position, and the speed transfer operation member. (12) is achieved by returning to the double action position by the force of the tension spring (32).

In this way, it is possible to release the engagement of one of the operation members 11 (12) held at the king operating position, and the predetermined position of the other operation member 12 (11) necessary for rotating the locking member 46. The operation amount up to is defined as [detachment release amount] in this embodiment. This [detent release amount] is a lower operating amount than the above-mentioned [direction change amount].

On the other hand, the operation force transmission member 44 is a shaft 52, which is installed on the substrate 1 as shown in FIG. 12 together with the pinch roller arm 51 that freely supports the pinch roller 7 on the right side described above. It is supported freely in rotation. The operating force transmitting member 44 is provided on the inner side of the pressing portion 53 facing the arc surface 37 of the tape traveling direction switching member 33 and the following portion 46a of the locking member 46. A nail-shaped projecting piece 54 in contact with each other, a V-shaped pressing piece 55 subjected to a pressing force by the pressing piece 24 of the rewinding operation member 11, and an upper surface of the substrate 1 It consists of the pressing pieces 56 and 57 which engage with the auto reverse mechanism which is not shown in figure.

Since this autoreverse mechanism is already known from Japanese Patent Application Laid-Open No. 60-138752, the detailed description thereof is omitted, but basically, the tape traveling direction is reversed whenever the tape traveling in one direction reaches the tape end. . The operating force transmission member 44 generates the same state as when reaching the tape end with respect to the autoreverse mechanism by the rotational movement, thereby switching the running direction of the tape.

In this way, the operation force transmission member 44 switches the tape traveling direction when both of the operation members 11 and 12 are operated at the same time as described above and the tape traveling direction switching member 33 moves in the arrow C direction. The circular arc surface 37 of the member 33 pushes and rotates.

Therefore, by simultaneously operating the reciprocating motions of both of the operation members 11 and 12, the operation force transmission member 44 is inserted into the tape travel direction switching member 33 so that the autoreverse mechanism can be started to switch the tape travel direction.

Moreover, this operation force transmission member 44 is pressed by the pressing piece 24 even when the pressing piece 24 is joined to the V-shaped hydraulic pressure piece 55 during the reciprocating movement of the rewinding operation member 11. Rotate directly. The joining of the pressing piece 24 and the V-shaped hydraulic piece 54 is performed so that the rewinding operation member 11 is operated at the position where only the above-mentioned "direction change amount" is operated. In other words, when the rewinding operation member 11 passes the position in the reciprocating direction and when passing in the reciprocating direction, the operating force transmission member 44 is rotated, and the autoreverse mechanism is started each time. You can switch to the tape running direction. When the rewinding mode is canceled by switching to the tape running direction accompanying the reciprocating movement of the rewinding operation member 11, the regeneration mode for running the tape in the original running direction is restored.

The device of this embodiment is characterized in that a moving amount regulator 58 is provided in addition to the above-described mechanism.

As shown in FIG. 3, the movement amount restrictor 58 protrudes the shaft 60 on one lower surface of the plate-shaped body 59 and protrudes the stopper portion 61 on the other upper surface. Has The moving amount restrictor 58 engages the shaft 60 in the engaging groove 62 of the guide plate 15 so as to rotate freely on the guide plate 15, and the respective operation members 11, 11. In the same direction as 12), only a predetermined amount is freely mounted.

In addition, a locking projection 63 engaging with the V-shaped locking groove 64 provided on one side edge of the guide plate 15 is provided on the lower surface of the middle portion of the plate-shaped body 59. In addition, the movement amount restrictor 58 is an elastic support force of the tension spring (elastic member) 66 placed on the shaft 60 and the spring joint 65 provided on the guide plate 15, and the locking projection 63 Is in a neutral position to be engaged with the locking groove (64). By this elastic bias to the neutral position, the movement amount restrictor 58 has an axis 1 ₁ (see FIG. 3) passing through the center of the shaft 60 and the center of the engaging projection 63. It is maintained in parallel with the reciprocating direction of the operation member (11, 12).

On the other hand, each of the operation members 11 and 12 is provided with L-shaped contact portions 67 and 68 cut inward to each other and arc-shaped push receding portions 69 and 70 continuous thereto. These pressing receding pieces 69 and 70 are moved amounts held in the neutral position by the elastic bearing force of the tension spring 66 when one of the operating members 11 and 12 swings in the direction of arrow C at the reciprocating position thereof. By sliding contact of the restrictor 58 to the side of the stopper portion 61, the movement amount restrictor 58 is rotated in the opposite direction about the axis 60. The stopper portion 61 is positioned in the reciprocating path of the other operation members 11 and 12 by the rotational movement of the movement restricting member 58 so as to be brought into contact with the contact portions 67 and 68. do.

That is, in the state where both the operating members 11 and 12 are in the reciprocating position in the arrow D direction, the movement amount restrictor 58 is maintained at the neutral position by the elastic support force of the tension spring 66. And as shown in FIG. 4, the stopper part 61 is located between the contact parts 67 and 68 of both operating members 11 and 12, and the reciprocating path | route of any of these contact parts 67 and 68 is carried out. Deviating from

In such a state, for example, when the rewinding operation member 11 is reciprocated in the direction of arrow C, the movement amount restrictor 58 is pressed by the pressing retreat 69 and rotates clockwise in the fourth way. When the stopper portion 61 reciprocates the speedy transfer control member 12 in the direction of arrow C, as shown in FIG. 5, the movement amount restrictor 58 is pressed by the pushback recess 70. The stopper part 61 is located on the reciprocating motion path of the contact part 69 of the rewinding operation member 11, as shown in FIG. .

Then, when the operation members 11 and 12 remaining in the king operating position in the state shown in FIG. 5 or 6 are subjected to the king operation, the operation members 11 and 12 are placed on the stop operation path. The contact amount between the contact portion 61 and the contact portions 67 and 68 restricts the amount of movement, which prevents the operation from exceeding the contact position. The control amount of operation of the operation members 11 and 12 by the movement amount restrictor 58, that is, the operation members 11 and 12 by abutting the contact portions 67 and 68 and the stopper portion 61, respectively. The amount of the motion limiting operation is equal to or greater than the above-described "hang release amount" and is set to an amount S smaller than the "direction change amount".

In this way, according to the movement amount restricting body 58, if the speed transfer control member 12 is operated in the direction of arrow C in the set state of the rewind mode shown in FIG. 5, the rewind operation is performed as described above. Even when the member 11 is released, the abutting portion 68 abuts against the stopper 61 of the movement amount restrictor 58, thereby preventing further lifting. Therefore, since the speed governing operation member 12 does not operate until the "directional telephone amount" and the "mode setting amount", only the release of the rewinding operation member 11 is reliably executed to ensure the original reproduction in the rewind mode. You can certainly switch modes to mode.

Similarly, when the rewinding operation member 11 is moved in the direction of arrow C in the setting state of the speeding mode shown in FIG. 6, the contacting part (after the release of the speeding operation part 12) is released. 67) abuts against the stopper portion 61 of the movement amount restricting member 58, so that the rewinding operation member 11 does not operate until the [direction switching amount] and the [mode setting amount]. Therefore, even in this case, only the release of the fast-moving operation member 12 can be surely executed, and the mode can be reliably executed from the fast-moving mode to the original regeneration mode.

The relationship between the movement amount S regulated in this way and the reciprocating amount of movement of the operation members 11 and 12 in each operation setting described above is as shown in FIG.

According to the embodiment apparatus provided with the movement amount restricting member 58 as described above, one of the rewinding operation member 11 or the fast-feeding operation member 12 is caught in its royal operation position and the rewinding mode or the tidal transfer mode is set. When the other operation member is operated by releasing the latch of the operation member, the operation member is not moved to an unintentional position. Then, only the release of one of the operation members can be secured, and the original playback mode can be switched. Furthermore, the mode change can be assured by the simple structure of providing the movement amount restrictor 58. In addition, since it is not necessary to add or subtract the kinetic operation amount of the operation member by hand, the operability can be greatly improved.

Next, another embodiment of the present invention will be described with reference to FIGS. 14 and 15. In this embodiment, the same parts as those in the first embodiment shown in FIGS. 1 to 13 described above are denoted by the same reference numerals, and detailed description thereof will be omitted.

In this embodiment, the moving amount regulator 58 protrudes the pin-shaped stopper portion 73 at the center of the upper surface of the circular cylindrical portion 72 having the annular groove 71 on the outer circumferential surface thereof, and at the same time, the pin shape at the center of the lower surface. It has a structure which protruded the spring joint part 74 of.

The moving amount restrictor 58 'having such a structure is manufactured by, for example, cutting.

On the other hand, the guide plate 15 is provided with a V-shaped groove 75 and an insertion hole 76 continuous with the V-shaped groove 75. The moving amount restrictor 58 'engages the annular groove 75 of the circular cylindrical portion 72 with the circumference of the groove 75 through the insertion through hole 76, and the spring fitting portions 74 and 65. The tension spring 66 is hypothesized between and, and it is attached to the groove 75 of the guide plate 15 freely for rotational movement and for sliding freely. In this mounting state, the movement amount restrictor 58 'is elastically supported by the elastic spring force of the tension spring 66 so as to be elastically supported as if it is located in the bent portion of the groove 75, and is maintained at the neutral position.

In the apparatus configured as described above, the stopper portion of the movement amount restricting member 58 'is moved when the rewinding operation member 11 is operated by the locking mechanism 43 so that the locking mechanism 43 is engaged in the running position, and the rewinding mode is set. 73 abuts against the pressing recess 69 in the reciprocating motion of the rewinding operation member 11, and is retracted by pressing in one direction (downward in FIG. 15) at a neutral position. As a result, as shown in FIG. 15, the movement amount restricting member 58 'is placed in the state in which the stopper portion 73 is placed on the running path of the abutting portion 68 of the speedy transfer control member 12. As shown in FIG. .

In this state, the above-mentioned spacing S is set between the stopper portion 73 of the movement amount restrictor 58 'and the abutting portion 68 of the speed control operation member 12. Therefore, in order to release the rewind mode and return to the original playback mode, press the quick turn operation button 12a to operate the fast-moving control member 12 to make the contact portion 68 move with the movement amount regulator 58 '. In the process until it comes in contact with the stopper portion 73 of (), the retraction of the rewinding operation member 11 is released, and then the movement of the speeding transfer member 12 is regulated. Therefore, as in the previous embodiment, there is no fear of excessively pressing the speed feed operation button 12a.

Further, when the rewinding operation member 11 is reciprocated in the state in which the speed control mode is set and returned to the original regeneration mode, the stopper portion 73 of the movement amount restrictor 58 'is returned as described above. Since the gap S is set between the stopper portion 73 'and the abutment portion 67 of the rewinding operation member 11, the gap S is set on the ridge path of the abutment portion 67 of the winding operation member 11. In this way, it is possible to reliably shift to the original regeneration mode by releasing the jamming of the speed feed operation member 12 without excessively pressing the rewinding operation member 11.

Therefore, even if the movement amount restrictor 58 'shown in this embodiment is used, mode switching of the tape recorder can be assured.

As described above, according to the present invention, when one of the operation members is caught in the reciprocating position and the rewind mode or the rapid transfer mode is set, the moving amount of the other operation member regulates the amount of movement of the other operation members, so that the rewinding mode or When excessively operating the other operation member to release the speed control mode and return to the original regeneration mode, the excessive press can be effectively prevented. In addition, the simple configuration makes it possible to prevent excessive pressing of the jaw member and to ensure mode switching. And the operability can be improved significantly.
