Next, each mode of this day precoder with the above structure is demonstrated.

6 to 9 show the stop mode of the tape recorder, and by pressing the play button 11 in the stop mode, the tape recorder is switched to the play motor shown in FIG.

That is, when the regeneration button 11 is pressed, the regeneration lever 28 rotates counterclockwise in FIG. 10 centering on the pin 27, and the fixed portion 31 at the tip of the lever 28 is rotated. ) Is fixed by the fixing part 55 of the stop lever 52, so that the regeneration lever 28 is maintained in the reciprocating position. And the head board feedback lever 78 associated with this lever 28 and the spring 33 by the revolving movement of this regeneration lever 28 is centered on the pin 35, In FIG. It rotates clockwise and the pressing piece 81 of this lever 78 presses the edge of the lower end side in FIG. 10 of the head board 82. As shown in FIG. For this reason, the head board 82 is guided to the U-shaped groove 85 which the guide pin 83 and the roller 86 engage, and moves upward in FIG. 10 against the coil spring 87. As shown in FIG. Therefore, the recording / reproducing head 88 supported on the head substrate enters the cassette 5 from the front opening of the cassette 5 and contacts the magnetic tape.

In addition, the pinch roller lever 90, which has been blocked by the long hole 96 of the head substrate S2 by the tumbling of the head substrate 82, is also capable of reciprocating. The pinch roller lever 90 rotates counterclockwise around the pin 89 by the coil spring 93, and the pinch roller 95 supported by the lever 90 moves the magnetic tape. The capstan 130 is pressed against. The capstan 130 is driven by the motor 125 through the motor pulley 126, the belt 128, and the flywheel 127, so that the magnetic tape pressed against the capstan 130 may be driven. do.

In addition, when the pinch roller lever 90 rotates, the pressing piece 97 of the lever 90 moves upward in FIG. 10, and thus the pressing piece 97 causes the king to move through the pin 162. The idler switching lever 159, which has been blocked, is tensioned by the coil spring 160 via the idler support lever 157, and rotates clockwise in FIG. 10 around the pin 161. The idler support lever 157 connected through the idler switching lever 159 and the pin 158 moves upward and upward in FIG. 10, and the take-up idler 156 supported by the lever 157 The friction wheel of the driving wheel 146 of the rail stand 138 on the winding side of the friction wheel 135 sphere of the fly wheel 127 is in contact with it.

Therefore, the rotation of the flywheel 127 is transmitted to the rail stand 138 on the winding side via the take-up idler 156 and the driving wheel 146, and the magnetic tape that has traveled is engaged with the rail stand 138. It is wound up by the rail and a predetermined reproducing operation is performed.

When the tape recorder is stopped in the regeneration mode, the stop button 18 is rotated by pressing the stop button 18, and the fixing portion 31 of the lever 52 and the retentive lever 28 of the regeneration lever 28 are rotated. Unlock with). As a result, the regeneration lever 28 is reciprocated and the tape recorder is switched to the stationary mode.

In the tape recorder, for example, even if the eject button 13 is indeed pressed in the playback mode, the tape recorder is first switched to the stop mode, and then the cassette ejection is performed.

That is, when the eject button 13 is pressed as shown in FIGS. 13 to 15, the inclined portion 112 of the eject slider 105 integrated with the eject button 13 is first. The left end is pressed in FIG. 13 of the stationary slider 113, and this slider 113 is moved to the right in FIG. Then, the right end of the slider presses the locking piece 53 of the stop lever 52 and rotates the stop lever 52 counterclockwise around the point pin 36 in FIG. Therefore, the fixing portion 55 of the lever 52 and the fixing portion 31 of the regeneration lever 28 are released, whereby the tape recorder is switched from the regeneration motor to the stop mode.

When the eject button larger than the stroke required to release the regeneration lever 28 is pressed in this manner, the tip of the eject slider 105 presses the pin 108 to point the eject lever 107. It rotates clockwise in FIG. 14 about the pin 110. As shown in FIG. Then, the eject piece 111 of the eject lever 107 pushes the bottom face of the tape cassette 5 to eject the cassette 5 from the cassette mounting position.

Thus, in this tape recorder, even if the eject button is pressed, the instant cassette is first switched to the stop mode without ejecting, and then the ejection of the cassette 5 is performed. , 88, pinch rollers 95, capstan 130, cassette 5, and the like, can be prevented in advance. Also, in the regeneration mode, when the poise button 15 is pressed, a poise mode in which traveling of the magnetic tape is temporarily stopped is obtained. That is, when the poise button 15 is pressed in the playback mode shown in FIG. 10, the poise slider 100 slides to the left in FIG. 16 as shown in FIG. Defendant 103 is stopped by stop pin 29 on regeneration lever 28. In addition, the fixation of the poise slider 100 is not stopped unless the regeneration lever 28 is in the reciprocating position, and hence the poise operation is not performed except in the reproducing or recording mode.

The pressing piece 104 of the tip of this slider 100 presses the to-be-pressed arm 98 of the pinch roller lever 90 by the fluctuation of the poise slider 100, and this lever 90 is pin 89 It rotates clockwise in FIG. 16 centering on. For this reason, the pinch roller 95 supported by this pinch roller lever 90 is separated from the capstan 130, and crimping | compression of the magnetic tape to the capstan 130 is canceled | released. Therefore, the continuous running of the magnetic tape is also released. In addition, by the rotation of the pinch roller lever 90, the pressing piece 97 of the lever 90 presses the pin 162 of the idler switching lever 159, and the lever 159 is centered on the pin 161. Rotate in the counterclockwise direction in FIG. 16 to separate it from the idler 156 friction wheels 135 and 148 on the idler support lever 157 connected by the lever 159 and the pin 158. The drive of the rail zone 138 is released. For this reason, the magnetic tape stops temporarily. To release this poise, the poise button 15 is pushed upward in FIG. Since the hole 99 into which the point pin 35 is fitted is formed in a triangular shape, the poise slider 100 rotates counterclockwise around the pin 83 in FIG. The engagement between the fixed part 103 of the slider 100 and the fixing pin 29 of the regeneration slider 28 is released, whereby the poise slider 100 is restored to the right by the coil spring 102. . With the double acting of the poise slider 100, the pinch roller lever 90 also returns to its original position by the coil spring 93, and the pinch roller 95 compresses the magnetic tape against the capstan 130, and then the idler. 159 is also in contact with the friction wheels 135 and 148, so that the rail 138 is also driven to return to the regeneration mode.

When the stop button 18 is pressed during the poise operation, the stop lever 52 rotates to engage the fixing part 55 of the lever 52 with the fixing part 31 of the regeneration lever 28. Is released, and thus the regeneration lever 52 rotates clockwise in FIG. 16 around the point pin 27. As shown in FIG. Accordingly, the fixing pin 29 of the lever 52 also moves downward in FIG. 16 and the fixing of the poise slider 100 is released, and the poise slider 100 doubles by the coil spring 102. Thus, this poise operation is automatically released by switching to the stop mode.

Next, the operation of the recording mode will be described with reference to FIG.

This recording mode is achieved by pressing the recording button 10 in the stationary mode shown in FIG. That is, the pin 35, 36, 37 is guided by the pressing of the recording button 10, and the recording slider 38 slides upward in FIG. And the retaining part 41 of this slider 38 engages with the fixed part 50 of the fixed lever 48, and the slider 38 is fixed in a reciprocating position, and the erasing head 40 supported on this slider is carried out. Enters the cassette 5 and contacts the magnetic tape. In response to the movement of the recording button 10, the back of the button 10 presses the pressure-pressed portion 30 of the regeneration lever 28, and the regeneration lever 28 is centered on the point pen 27. Rotate clockwise at 17 degrees. If an elastic member, for example, a leaf spring 201 or the like is interposed between the back surface of the recording button 10 and the pressurized portion 30 of the regeneration lever 28, the pressing of the recording button 10 is performed. The overstroke of the regeneration lever 28 is absorbed, and the regeneration lever 28 is secured.

When the regeneration lever 28 is pressed by the recording button 10, the lever 28 rotates counterclockwise in FIG. 17 with the pin 27 as the center. The defendant portion 31 is stopped by the stop portion 55 of the stop lever 52, whereby the regeneration lever 28 is maintained in the revolving position. Then, by the revolving movement of the regeneration lever 28, the head board feedback lever 78 associated with the lever 28 and the spring 33 has a clock in FIG. 17 centering on the pin 35. Direction, the pressing piece 81 of the lever 78 presses the edge of the lower end side in FIG. 17 of the head substrate 82. For this reason, the head board 82 is guided to the U-shaped groove 85 in which the guide pin 83 and the roller 86 engage, and the coil spring 87 opposes and moves upwards in FIG. Therefore, the recording / playback head 88 supported by the head substrate 82 and switched to the recording state by the circuit switching switch other than the above enters into the cassette 5 from the front opening of the cassette 5, and the magnetic tape and Contact.

In addition, the pinch roller lever 90 in which the thrust movement is prevented by the long hole 95 of the head substrate 82 by the thrust of the head substrate 82 also becomes a state in which thrust movement is possible. The pinch roller lever 90 rotates counterclockwise in FIG. 17 with the coil spring 93 as the pin spring roller 93, and the pinch roller 95 supported by the lever 90. Presses the magnetic tape against the capstan 130. Since the capstan 130 is rotated by the motor 125 through the motor pulley 126, the belt 128, and the flywheel 127, the magnetic tape to be compressed to the capstan 130 is driven. do·

Moreover, when the pinch roller lever 90 pivots, the press piece 97 of this lever 90 will move up in FIG. 17, and the press piece 97 will move through the pin 162. The idler switching lever 159, which is supported for rotation, is tensioned by the coil spring 160 via the idler support lever 157, and rotates clockwise in FIG. 17 around the pin 161. The idler support lever 157 connected via the switching lever 159 and the pin 158 moves upward and upward in FIG. 17, and the take-up idler 156 supported by the lever 157 is plyed. The friction wheel 135 of the wheel 127 and the friction wheel 148 of the drive wheel 146 of the rail stand 138 on the winding side are contacted. Therefore, the rotation of the flywheel 127 is transmitted to the rail stand 138 on the winding side through the take-up idler 156 and the driving wheel, and the magnetic tape driven by the rail is wound by the rail engaging with the rail stand 138. A predetermined recording operation is performed.

In this recording mode, since the regeneration lever 28 is moving, the mode of the magnetic tape is also temporarily stopped and the poise operation is performed in this mode as well. This operation is described with reference to FIG. 18 as follows.

When the poise button 15 is pressed in the recording mode shown in FIG. 17, as shown in FIG. 18, the poise slider 100 slides to the left in FIG. 18, and the defendant of the slider 100 The government 103 is fixed by the fixing pin 29 on the regeneration lever 28. In addition, the fixation of the poise slider 100 is not fixed when the reproducing lever 28 is in the revolving position or, therefore, the poise operation is not performed except in the reproducing or recording mode.

By vibrating the poise slider 100, the pressing piece 104 at the tip of the slider 100 presses the presser arm 98 of the pinch roller lever 100, and the lever 90 is pushed by the pin 89. It rotates clockwise in FIG. 18 based on a center. For this reason, the pinch roller 95 supported by this pinch roller lever 90 is separated from the capster 130, and the crimp of the magnetic tape to the capstan 130 is released. Therefore, the regular driving of the self-tape is also released. In addition, by pressing the pinch roller lever 90, the pressing piece 97 of the lever 90 presses the pin 162 of the idler switching lever 159, and the lever 159 is centered on the pin 161. 18, the idler 159 on the support lever 157 connected by the lever 159 and the pin 158 is rotated by the friction wheels 135 and 148. The driving of the rail stand 138 is released by spaced apart. For this reason, the magnetic tape temporarily stops running.

To release the poise mode, the poise button 15 is pushed upward in FIG. Since the holes 99 fitted with the point pins 35 are formed in a triangular shape, the poise slider 100 rotates counterclockwise around the pins 83 in FIG. The engagement between the fixed part 103 of the slider 100 and the fixing pin 29 of the regeneration slider 28 is released, whereby the poise slider 100 doubles to the right by the coil spring 102. . With the double acting of the poise slider 100, the pinch roller lever 90 also returns to its original position by the coil spring 93, and the pinch roller 95 presses the magnetic tape against the capstan 130. The idler 159 is also in contact with the friction wheels 135 and 148 so that the rail 138 is also driven to return to the recording mode.

Next, the release of the recording mode shown in FIG. 17 will be described. To stop the recording mode and set the stop mode, the stop button 18 is pressed. By pressing the stop button 18, the stop lever 52 rotates counterclockwise around the point pin 36 in FIG. 17 against the coil spring 54. As shown in FIG. For this reason, the regeneration lever 28 stopped by the stop part 55 of this stop lever 52 is canceled | released.

When the regeneration lever 28 is released, the lever 28 rotates clockwise in FIG. 17 around the point pin 27. Then, the head substrate feedback lever 78 connected by the lever 28 and the spring 33 also rotates counterclockwise in FIG. 17 with the point pin 35 as the center. Pressing of the head board 82 by the press piece 81 is released, and the head board 82 double-acts by the coil spring 87. FIG. For this reason, the playhead 88 falls off the magnetic tape, and the long hole 96 of the head substrate 82 presses the pin 94 so that the pinch roller lever 90 is centered around the pin 89. Rotate clockwise in. Thereby, the crimping of the magnetic tape by the pinch roller 95 to the capstan 130 is canceled | released, and the constant speed running of the magnetic tape is canceled | released. In addition, the pressing piece 97 of the lever 90 presses the pin 162 of the idler switching lever 159 by the double rotation of the pinch roller lever 90 to the lever 159 and the pin 158. The idler supported by the idler support lever 157 connected by it is separated from the friction wheels 135 and 148. This cuts off the transmission of the rotational force to the rail zone 138.

In addition, by the pressing operation of the regular button 18, the release arm 56, which is addressed to the button, presses the arm of the fixed lever 48 and sets the lever 48 against the coil spring 49. Turn counterclockwise in FIG. For this reason, the engagement between the fixed lever portion 48 and the fixing portion 41 of the recording slider 38 is released, the fixing of the recording slider 38 is released, and the slider 38 has a coil spring ( 42, it slides downward in FIG. Therefore, the erasing head 40 supported on the slider 38 retreats and falls from the magnetic tape in the cassette 5.

Next, the fast mode of the tape coder will be described with reference to FIG.

The fast feed mode is achieved by pressing the fast feed button 17 in the stop mode shown in FIG. That is, the rapid-sliding slider 60 slides to the left side in FIG. 19 in response to the coil spring 62 due to the fluctuation of the quick-feed button 17, and the fixed part 63 of the slider 60 is fixed-slider ( 70 is oriented upward in FIG. 19, whereby the fixing portion 63 and the fixing portion 74 of the slider 70 are engaged. As a result, the rapid-sliding slider 60 is fixed at the king position shown in FIG.

The tip of the slider 60 moves to the left in FIG. 19 against the idler switching slider 65 in response to the fluctuation of the rapid-sliding slider 60. Accordingly, the gear switching lever 164, which has been prevented from rotating by the left side of the engaging recess 69 of the slider 65, becomes a rotatable counterpart, and the lever 164 is formed by the coil spring 166. It rotates counterclockwise in FIG. 19 about the support shaft 140 of 138, and the gear 163 supported on the lever 164 is meshed with the gear 137 of the flywheel 127. FIG. . Since the flywheel 127 is driven by the motor 125 through the motor pulley 126 and the belt 128, the bulb 146 of the rail stand 138 is driven by the flywheel 127. It is driven to rotate through the fast gear 163. Then, the rotation of the driving wheel 146 is carried out through the friction clutch and the driven wheel 141 made of the ring 149 made of felt, and the driven wheel 141 is a slit 153 of the sleeve 142. ) And the rail 138 engaged by the pin 152 so that the rail 138 rotates clockwise in FIG. 19 at a high speed. Therefore, the magnetic tape is wound at a high speed on the reel 195 on the winding side engaged with the reel zone 138, and the tape coder is switched to the fast feed moder.

Next, the operation of releasing the fast feed mode and switching to the stop mode will be described. This operation is achieved by pressing the stop button 19 in the fast feed mode shown in FIG. That is, when pressing the stop button 18, the stop lever 52 rotates counterclockwise in FIG. 19 centering on the point pin 36, and the lock release arm 56 of this lever 52 is rotated. ) Presses the inclined portion 75 of the fixed glider 70 to move the slider 79 upward in FIG. At this time, the engagement of the fastening slider 60 of the fastening slider 60 of the fixing part 74 of the slider 70 is released and the fast feeding slider 60 is turned to the right in FIG. 19 by the coil spring 62. Double acting. Therefore, the idler switching slider 65 pushed to the left by the rapid-sliding slider 60 also doubles to the right side in FIG. 19 by the coil spring 68. As a result, the gear switching lever 164 connected by the recess 69 and the bending piece 165 of the slider 65 rotates clockwise about the support shaft 140 of the rail 138. The gear 163 on the lever 164 is spaced apart from the gear 137 of the flywheel 127. Therefore, transmission of the rotational force from the flywheel 127 to the rail zone 138 is cut off, and the rotation of the rail zone 138 is stopped to become a stop mode.

Next, the rewinding mode of the tape recorder will be described with reference to FIG. The rewind mode is achieved by pressing the rewind button 16 in the stop mode shown in FIG. That is, when the rewind button 16 is pressed, the rewind lever 57 rotates clockwise in FIG. 20 around the point pin 37. Then, the lever 57 presses the idler switching lever 117 and rotates the lever 117 counterclockwise in FIG. 20 with the coil spring 118 facing the point pin 36. Therefore, the support of the rotation of the memory switching lever 169 in the clockwise direction by the tip of the lever 117 is released so that the switching lever 169 is clockwise by the coil spring 172. Rotate to As a result, the rewinding gear 170 supported by the lever 169 meshes with the gear 137 of the flywheel 127. Therefore, the rotation of the flywheel 127 which is rotationally driven by the motor 125 is transmitted to the driving wheel 147 of the rail stand 139 through the gear 170 and the intermediate gear 167. The rotation of the driving wheel 146 is again engaged by the slit 153 and the pin 152 of the sleeve 142 of the driven wheel through the friction clutch and the driven wheel 141 made of the felt ring 49. It is transmitted to the rail zone 139 and the rail zone 139 rotates counterclockwise in FIG. 20 at high speed. Accordingly, the magnetic tape is wound at a high speed on the rail 196 on the feeding side engaged with the rail zone 139, whereby the rewinding operation is performed.

Next, the operation of releasing this rewind mode and switching to the stop mode will be described. This operation is achieved by pressing the stop button 18 in the rewind mode shown in FIG. That is, when pressing the stop button 18, the stop lever 52 is rotated counterclockwise in FIG. 20 centering on the point pin 36, and the stop release arm 56 of this lever 52 is rotated. ) Presses the inclined portion 15 of the fixed slider 70 and moves the slider 70 upward in FIG. For this reason, the engagement between the fixing portion 75 of the slider 70 and the fixing portion 73 of the retaining portion 70 of the retracting lever 57 and the retracting portion of the rewinding lever 57 is released. The rewinding lever 57 rotates counterclockwise in FIG. 20 with the point pin 37 in the center. Accordingly, the idler switching lever 117 also rotates clockwise by the coil spring 118, and the tip of the lever 1l7 supports the gear 170, and a pin implanted in the gear switching lever 169. Press 170 is pressed. For this reason, the gear switching lever 169 rotates counterclockwise in FIG. 20 against the coil spring 172 about the pin 168, and the gear 170 supported by this lever 169 and Engagement with the gear 137 of the flywheel 127 is released. Accordingly, the rotation of the flywheel 127 from the flywheel 127 to the rail band 139 is stopped, and the stop mode is obtained.

Next, the operation of the cuu mode of the tape recorder will be described based on FIG. The cuu mode is an operation in which the magnetic tape is temporarily conveyed at a high speed in the reproducing mode, and is achieved by pressing the fast feeding button 17 in the reproducing mode shown in FIG. That is, this is achieved by pressing the fast feed button 17 in the playback mode. That is, when the quick feed button 17 is pressed in the regeneration mode, the quick feed slider 60 moves to the left in FIG. 21 against the coil spring 62. However, the pressurized portion 76 of the fixed slider 70 is pressed by the pressing surface 77 of the regeneration lever 28 in the revolving position, so that the fixed slider 70 is fixed upwardly in FIG. Since it moves to the release position, the rapid-sliding slider 60 is not fixed by the fixed slider 70.

Then, the pressing piece 64 of the slider 60 presses the arm 80 of the head board feedback lever 78 by the rush of the rapid-sliding slider 60, and the lever 78 is connected to the point pin 35. At the center, in the counterclockwise direction in FIG. Then, the pressing of the head substrate 82 by the pressing pin 81 of the lever 78 is released and double-acted by the head spring 82 of the coil spring 87.

For this reason, the recording / reproducing head 88 is slightly separated from the magnetic tape and rotates clockwise in FIG. 21 centering on the long hole 89 of the head substrate 82. As a result, the pressing of the magnetic tape to the capstan 130 by the pinch roller 95 is released, and the constant speed travel of the magnetic tape is released to one seat.

Moreover, by the double rotation of the pinch roller lever 90, the pressing piece 97 of this lever presses the pin 162 of the idler switching lever 159, and is connected by this lever 159 and the pin 158. The idler 156 supported by the idler support lever 157 is spaced apart from the friction wheels 135 and 148. Thereby, transmission of the rotational force to the rail zone 138 is also temporarily stopped. In addition, the tip of the slider 60 presses the idler switching slider 68 and moves the switching slider 65 to the left in FIG. 21 due to the fluctuation of the rapid slider 60 in opposition to the coil spring 68. Let's do it. Therefore, the gear switching lever 164, which has been prevented from turning by the left side of the engaging recess 69 of the slider 65, becomes a rotatable counterpart. The gear 163 rotated counterclockwise in FIG. 21 around the support shaft 140 of 138 and supported on the lever 164 is engaged with the gear 137 of the flywheel 127. . Since the flywheel 127 is rotationally driven by the motor 125 through the motor pulley 126 and the belt 128, the driving wheel 146 of the rail stand 138 is conveyed by the flywheel 127. It is driven to rotate through the gear 163. Then, the rotation of the driving wheel 146 is again performed by the slit 153 and the pin 152 of the slave 142 of the driven wheel 141 through the friction clutch and the driven wheel 141 of the felting ring 149. It is transmitted to the engaging rail 138, and the rail 138 rotates clockwise in FIG. 21 at a high speed. Therefore, the magnetic tape is temporarily wound at a high speed on the reel 195 on the winding side engaged with the reel zone 138, and the tape recorder can be switched to the cuu mode.

In addition, as described above, in the fast cue mode, the fast button 17 is not fixed. If the finger is released from the fast button 17 and the pressure button 17 is released, the fast feed slider 60 is coiled. The spring 62 doubles to the right in FIG. Therefore, the idler switching slider 65 which was lined to the left by this rapid-sliding slider also doubles to the right in FIG. 21 by the coil spring 68. FIG. As a result, the gear switching lever 164 connected by the recess 69 and the bending piece 165 of the slider 65 rotates clockwise about the support shaft 140 of the rail 138. The gear 163 on the lever 164 is spaced apart from the gear 137 of the flywheel 127. Therefore, the transmission of the rotational force to the flywheel 127 rail region 138 is interrupted.

In addition, by releasing the pressing force of the quick feed button 17, the pressing of the head board tightening lever 78 by the pressing piece 64 of the fast feed slider 60 is also released, and the head board tightening lever 78 is a spring 33. Rotates clockwise in FIG. 21 around the point pin 35. FIG. For this reason, the press piece 81 of this lever 78 is pressed by the edge part of the lower end side in FIG. 21 of the head board 82. As shown in FIG. For this reason, the head board 82 is guided to the U-shaped upper groove 5 where the guide pin 83 and the roller 86 engage, and move upward in FIG. 21 against the coil spring 87. Therefore, the recording / playback head 88 supported on the head substrate 82 enters the cassette 5 from the front opening of the cassette 5 and contacts the magnetic tape again.

In addition, the pinch roller lever 90, which was supported by the long hole 96 of the head substrate 82 by the tumbling of the head substrate 82, is also capable of reciprocating. The pinch roller lever 90 rotates counterclockwise around the pin 89 by the coil spring 93, and the pinch roller 95 supported by the lever 90 again capstans the magnetic tape. It presses against 130.

Since the capstan 130 is rotationally driven by the rotor 125 through the rotor pulley 126, the belt 128, and the flywheel 127, the magnetic tape compressed to the capstan 130 may resume driving. do.

In addition, when the pinch roller lever 90 rotates, the pressing piece 97 of the lever 90 moves upward in FIG. 21, so that the pressing piece 97 rotates through the pin 162. The idler switching lever 159, which has been held in place, is tensioned by the coil spring 160 via the idler support lever 157, and rotates clockwise in FIG. 21 with respect to the pin 161. The idler support lever 157 connected via the 159 and the pin 158 moves to the upper right in FIG. 21, and the take-up idler 156 supported by the lever 157 is again a flywheel. The friction wheel 135 of 127 and the friction wheel 148 of the bulb 146 of the rolling table 138 on the winding side are contacted. Therefore, the rotation of the flywheel 127 is transmitted to the rail stand 13S on the winding side through the take-up idler 156 and the driving wheel, and the traveling magnetic tape is wound up by the rail engaging with the rail stand 138. Then, the regeneration operation is performed again.

Next, the operation of the record viewer of this tape recorder will be described with reference to FIG. The view mode is an operation of temporarily returning the magnetic tape to a high speed in the regeneration mode, and is achieved by pressing the rewind button 16 in the regeneration motor shown in FIG. That is, by pressing the rewind button 16 in the regeneration motor, the rewind lever 57 rotates clockwise in FIG. 22 with the support pin 37 as the center. However, the pressing portion 76 of the fixed slider 70 is pressed by the pressing piece 77 of the regeneration lever 28 in the revolving position, so that the fixed slider 70 is upward in FIG. 22. That is, the lever 57 is retracted to the unlocking position, and therefore the rewinding lever 57 is not fixed by the fixed slider 70.

And by the revolving movement of the rewinding lever 57, the pressing piece 59 of this lever 57 presses the arm 80 of the head board rewinding lever 78, and this lever 78 is pushed by the point pin 35 ), The micro angle and the double rotation are rotated counterclockwise in FIG. Then, the pressing of the head board 82 by the press piece 81 of this lever 78 is released, and the head board 82 double-acts by the coil spring 87. As shown in FIG. For this reason, the recording / reproducing head 88 is slightly separated from the magnetic tape, and the long hole 96 of the head substrate 82 presses the pin 94 so that the pinch roller lever 90 is centered on the pin 89. Rotate clockwise in.

As a result, the pressing of the magnetic tape to the capstan 130 by the pinch roller 95 is released, and the constant speed traveling of the magnetic tape is temporarily released. In addition, the pressing piece 97 of the lever 90 presses the plate 162 to the pressing piece 97 of the lever 90 by the double rotation of the pinch roller 90 and is connected by the lever 159 and the pin 158. The idler 156 on which the idler lever 157 is supported is spaced apart from the friction wheels 135 and 148. As a result, the transmission of the rotational force to the rail zone 138 is also made temporary.

In addition, the lever 57 presses the idler switching lever 17 by the revolving movement of the rewinding lever 57, and the lever 117 is opposed to the coil spring 118 around the point pin 36. In Fig. 22 to rotate counterclockwise. Accordingly, the rotation of the gear switching lever 169 by the distal end of the lever 117 in contact with the pin 17 in the clockwise direction is released, and the switching lever 169 is clockwise by the coil spring 172. Is rotated to.

As a result, the rewinding gear 170 supported by the lever 169 meshes with the gear 137 of the flywheel 127. Therefore, the rotation of the flywheel 127, which is rotationally driven by the motor 125, is transmitted to the driving wheel 147 of the rail stand 139 through the gear 170 and the intermediate gear 167. Then, the rotation of the driving wheel 146 is again performed through the friction clutch and the driven wheel 141 made of the ring 149 made of felt, and the slit 153 and the pin 152 of the sleeve 142 of the driven wheel 141. Is delivered to the rail stand 139 which is engaged by the rail, so that the rail stand 139 rotates counterclockwise in FIG. 22 at a high speed. Accordingly, the magnetic tape is temporarily wound at a high speed on the rail 196 on the feeding side engaged with the rail zone 139, so that the rev operation is performed. As described above, since the rewind button 16 is not fixed in the reversing motor, when the release button 16 is released from the rewind button 16 and the pressure of the rewind button 16 is released, the rewind lever ( 57 is rotated counterclockwise in FIG. 22 with the point pin 37 as the center. Accordingly, the idler switching lever 117 also rotates clockwise by the coil spring 118, and the tip end of the lever 117 blocks the gear 170, and is further implanted in the gear switching lever 169. The pin 170 is pressed. For this reason, the gear switching lever 169 rotates counterclockwise in FIG. 22 against the coil spring 172 centering on the pin 168, and the gear 170 blocked by this lever 169. The meshing with the gear 137 of the flywheel of the will be released. Therefore, the transmission of the rotational force from the flywheel 127 to the reel zone 139 is totally cut off.

Further, the head board rewinding lever 78 is released as the pressing force of the head 78 rewinding lever 78 by the pressing piece 59 of the rewinding lever 57 by the release of the pressing of the rewinding button 16, and the head substrate rewinding lever 78 Rotates clockwise in FIG. 22 about the point pin 35 by a spring. For this reason, the press piece 81 of this lever 78 presses the edge of the lower end side in FIG. 22 of the head board 82. As shown in FIG.

For this reason, the head board 82 is guided to the magnetic hop 85 which the guide pin 83 and the roller 86 engage, and moves upward in FIG. 22 against the coil spring 87. As shown in FIG. Therefore, the recording / playback head 88 supported on the head substrate 82 enters into the cassette 5 from the front opening of the cassette 5 and comes in contact with the magnetic tape again.

In addition, the pinch roller lever 90, which has been blocked by the long hole 96 of the head substrate 82 due to the tumbling of the head substrate 82, is also capable of reciprocating movement. The pinch roller lever 90 rotates counterclockwise around the pin 89 by the coil spring 93, and the pinch roller 95 supported by the lever 90 again removes the magnetic tape. The capstan 130 is pressed against. Since the capstan 130 is driven by the motor 125 through the motor pulley 126, the belt 128, and the flywheel 127, the magnetic tape compressed to the capstan 130 may resume driving. do. In addition, when the pinch roller lever 90 rotates, the pressing piece 97 of the lever 90 moves upward in FIG. 22, so that the pressing piece 97 rotates through the pin 162 by the pressing piece 97. The idler switching lever 159 that was supporting the tensioner was tensioned by the coil spring 160 through the idler support lever 157, and rotated counterclockwise in FIG. 22 around the pin 161. The idler support lever 157, which is connected via the idler switching lever 159 and the pin 158, moves upward and upward in FIG. 22, and the rake-up idler 156 supported by the lever 157 Again, the friction wheel 135 of the flywheel 127 and the friction wheel 148 of the drive wheel 146 of the rail stand 138 on the winding side come into contact with each other. Therefore, the rotation of the flywheel 127 is wound by the rail engaging with the rail base 138 on the winding side via the take-up idler 156 and the driving wheel to perform the operation again.

Next, the operation of the one-touch cue of this tape recorder will be described with reference to FIG. The operation of this one-touch cue is a recording motor, which immediately switches to the cuu mode, and immediately switches to the playback mode by releasing the cue, so that the fast button 17 is pressed in the recording mode shown in FIG. Is achieved by pressing.

That is, when the fast feed button 17 is pressed in the recording mode, the fast feed button 17 moves to the left in FIG. 23 against the coil spring 62 of the fast feed slider 60. However, the pressing portion 76 of the fixed slider 70 is pressed by the pressing piece 77 of the regeneration lever 28 in the revolving position and the fixed slider 70 is fixed upwardly, i.e., fixed in FIG. Since it moves to the release position, the rapid-sliding slider 60 is not fixed by the fixed slider 70.

Then, the pressing piece 64 of the slider 60 presses the arm 51 of the fixed lever 48, and the lever 48 is centered on the support pin 36 by the tumbling of the slider 60. And rotates against the coil spring 49 in the counterclockwise direction in FIG. For this reason, the engagement of the fixing part 50 of this lever 48 and the fixing part 41 of the recording slider 38 is loosened | released, and the fixing of the recording slider 38 is released. Thus, the slider 38 is slid downward by the coil spring 42 in FIG. 23, and the erase head 40 supported by the slider 38 falls off the magnetic tape in the cassette 5. As shown in FIG. In addition, the double switch of the slider 38 switches the outside switch, so that the recording / reproducing circuit of the tape recorder is switched from the recording state to the reproduction state.

In addition, the pressing piece 64 of the slider 60 presses the arm 80 of the head board feedback lever 78 by the rapid movement of the slider 60 so that the lever 78 is centered on the point pin 35. In FIG. 23, it rotates counterclockwise although it is a small angle counterclockwise. Then, the pressing of the head substrate 82 by the pressing piece 81 of the lever 78 is released, and the head substrate 82 doubles by the coil spring 87. For this reason, the recording / reproducing head 88 slightly falls from the magnetic tape, and the hole hole 96 of the head substrate 82 presses the pin 94 so that the pinch roll lever 90 is centered on the pin 89. Rotate clockwise in the figure. As a result, the pressing of the magnetic tape to the capstan 130 by the pinch roller 95 is released, and the constant speed traveling of the magnetic tape is temporarily released. In addition, the pressing piece 97 of the lever 90 presses the pin 162 of the idler switching lever 159 by the double rotation of the pinch roller lever 90, and the lever 159 and the pin 158 The idler 156 supported by the idler support lever 157 connected thereto is spaced apart from the friction wheels 135 and 148. As a result, the transmission of the rotational force to the rail zone 138 is also temporarily interrupted. In addition, the tip of the slider 60 presses the idler switching slider 65 to move the switching slider 65 to the left in FIG. 23 against the coil spring 65 due to the fluctuation of the rapid slider 60. Let's do it. Therefore, the gear switching lever 164 which prevented rotation by the left part of the engaging recess 69 of this slider 65 becomes an opponent which can be rotated, and this lever 64 is a coil spring 166 by a coil stand. It rotates counterclockwise in FIG. 23 centering on the support shaft 140 of 138, and the gear 163 supported on this lever 164 is meshed with the gear 137 of the flywheel 127. FIG. All. Since the flywheel 127 is driven by the motor 125 through the motor pulley 126 and the belt 128, the driving wheel 146 of the rail stand 138 is fed by the flywheel 127. It rotates through the gear 163. The rotation of the driving wheel 146 is again performed by the slit 153 and the pin 152 of the sleeve 142 of the driven wheel 141 through the friction clutch made of the felt ring 149 and the driven wheel 141. Is delivered to the engaging rail 138, and the rail 138 rotates clockwise in FIG. 23 at a high speed. Therefore, the magnetic tape is temporarily wound at a high speed on the reel 195 on the winding side engaging with the rail 138, and the tape recorder is switched to the cuu mode.

In addition, as described above, the quick button 17 is not fixed in the cuu mode, so if the finger is released from the fast button, the quick feed slider 60 is connected to the coil spring 62. As a result, in Fig. 23, the abdominal pain is to the right. Therefore, the idler switching slider 65 pushed to the left by the rapid-sliding slider 60 also doubles to the right side at 23 degrees by the coil spring 68.

As a result, the gear switching lever 164 connected by the recess 69 and the bending piece 165 of the slider 65 rotates clockwise around the support shaft 140 of the rail 138. The gear 163 on the lever 164 is spaced apart from the gear 137 of the flywheel 127. Therefore, transmission of the rotational force from the flywheel 127 to the reel zone 138 is interrupted.

In addition, the pressing of the head substrate rewinding lever 78 by the pressing piece 94 of the rapid feeding slider 60 is also released by the release of the pressing of the fast feeding button 17, and the lever 78 rewinding the head substrate is a spring 33. Rotates clockwise in FIG. 23 with the point pin 35 as the center.

For this reason, the press piece 81 of this lever 7S presses the edge of the lower end side in FIG. 23 of the head board 82. FIG. As a result, the head substrate 82 is guided to the U-shaped groove 85 where the guide pin 83 and the roller 86 engage, and moves upward in FIG. 23 against the coil spring 87. Therefore, the recording / playback head 88 supported on the head substrate 82 and switched to the playback state enters the cassette 5 from the front opening of the cassette 5 and contacts the magnetic tape again.

In addition, the pinch roller lever 90 in which the thrust movement has been accumulated by the long hole 96 of the head substrate 82 is caused to be moved by the thrust of the head substrate 82. The pinch roller lever 90 rotates counterclockwise around the pin 90 by the coil spring 93, and the pinch roller 95 supported by the lever 90 again removes the magnetic tape. The capstan 130 is pressed against. Since the capstan 130 is driven to rotate through the motor pulley 126, the belt 128, and the flywheel 127 by the motor wheel 125, the magnetic tape that is attached to the capstan 130 resumes running. Done. In addition, when the pinch roller lever 90 rotates, the pressing piece 97 of the lever 90 moves upward in FIG. 23 so that the pressing piece 97 causes the king movement through the pin 162. The idler switching lever 159, which has been blocked, is tensioned by the coil spring 160 through the idler support lever 157, and rotates clockwise in FIG. 23 around the pin 161, and the idler switching lever is rotated. The idler support lever 157 connected via the 159 and the pin 158 moves to the upper right side in FIG. 23, and the take-up idler supported by the lever 157 is again the friction wheel of the flywheel. It contacts the 135 and the friction wheel 148 of the drive wheel 146 of the rail stand 138 on the winding side. Therefore, the rotation of the flywheel 127 is transmitted to the rail band 138 on the winding side through the take-up idler 156 and the driving wheel, and the magnetic tape driven by the rail band 138 and the rail 195 are engaged with each other. It is wound up and the play mode is manifested.

In this way, the operation of the one-touch cue releases the recording mode and immediately makes the cue mode, and switching from the cue mode to the playback mode is possible only by the operation of the quick button 17. All.

Next, the operation of the one-touch preview of this tape recorder will be described with reference to FIG. In addition, the operation of the one-touch revue is immediately switched from the recording mode to the revue mode, and immediately by the release of the revue mode to the playback mode as shown in FIG. 17. In other words, when the rewind button 16 is pressed in the recording mode, the rewind lever 57 rotates clockwise in FIG. 24 centering on the point pin 37. However, the fixed slider ( The pressed part 76 of 70 is pressed by the pressing piece of the regeneration lever 28 in the revolving position, so that the fixed slider 70 moves upward in Fig. 24, i.e., to the unlocked position, Therefore, the rewinding lever 57 is not fixed by the fixed slider 70.

And by the revolving rotation of the lever 57, the pressing piece 59 of this lever 57 presses the arm 51 of the fixed lever 48, and this lever 48 pushes the point pin 36. It rotates against the coil spring 49 counterclockwise in FIG. 24 based on a center. For this reason, the locking part 50 of this lever 48 and the fixing part 41 of the recording slider 38 are loosened | released, and the fixing of the recording slider 38 is released. Thus, the slider 28 is slid downward by the coil spring 42 in FIG. 24, and the erase head 40 supported by the slider 38 is separated from the magnetic tape in the cassette 5. As shown in FIG.

In addition, by the double acting of the slider 38, the switch other than that is switched, so that the recording / reproducing circuit of the tape recorder is switched from the recording state to the reproduction state. In addition, the pressing piece 59 of the lever 57 presses the lever 78, which presses the arm 80 of the lever 78 on which the head substrate is wound, by means of the yellowing movement of the rewinding lever 57. 35), a small angle and a double rotation are made counterclockwise in FIG. Then, the pressing of the head board 82 by the press piece 81 of this lever 78 is released, and the head board 82 double-acts by the coil spring 87. As shown in FIG. For this reason, the recording / reproducing head 88 slightly falls from the magnetic tape, and the long hole 96 of the head substrate 82 presses the pin 94 so that the pinch roller lever 90 is centered around the pin 89. Rotate clockwise in. As a result, the pressing of the magnetic tape to the capstan 130 by the pinch roller 95 is released, and the constant speed traveling of the magnetic tape is temporarily released. In addition, the pressing pin of the lever 90 presses the pin 162 of the idler switching lever 159 by the double rotation of the pinch roller lever 90 and is connected by the lever 159 and the pin 159. The idler 156 supported by the idler support lever 157 is spaced apart from the friction wheels 13 and 148. As a result, the transmission of the rotational force to the rail zone 138 is also temporarily interrupted.

In addition, the lever 57 presses the idler switching lever 117 by the revolving movement of the rewinding lever 57, and the lever 117 is driven against the coil spring 118 around the point pin 36. Rotate in the counterclockwise direction in FIG. Accordingly, the rotation of the gear switching lever 169 is prevented from clockwise rotation by the tip of the lever 117 in contact with the pin 171, and the switching lever 169 is clockwise by the coil spring 172. Rotate to

As a result, the rewinding gear 170 supported by the lever 169 meshes with the gear 137 of the flywheel 127. Therefore, the rotation of the flywheel 127 being rotated by the motor is transmitted to the driving wheel 147 of the rail stand 139 through the gear 170 and the intermediate gear 167. Then, the rotation of the driving wheel 146 is carried out again through the friction clutch of the ring 149 made of felt and the seed ring 141, and the slit 153 and the pin 152 of the sleeve 142 of the driven wheel 141. It is transmitted to the engaging rail 139, which is rotated counterclockwise in Figure 24 at a high speed. Therefore, the magnetic tape is temporarily wound at a high speed on the reel 196 on the sending side, which is engaged with the reel zone 139, whereby the rev operation is performed. In addition, as described above, the rewind button 16 is not fixed. Therefore, when the rewind button 16 is released from the rewind button 16 and the pressure of the rewind button 16 is released, the rewind lever ( 57 rotates counterclockwise in FIG. 24 centering on the point pin 37. As shown in FIG.

Accordingly, the idler switching lever 117 also rotates clockwise by the coil spring 118, and the tip end of the lever 117 supports the gear 170 and is implanted in the gear switching lever 169. The pin 170 is pressed. For this reason, the pin 170 implanted in the gear switching lever 169 is pressed. For this reason, the gear switching lever 169 rotates counterclockwise in FIG. 24 against the coil spring 172 centering on the pin 168, and the gear 170 supported by this lever 139 is supported. Meshing with the gear 137 of the flywheel 127 is released. Therefore, the transmission of the rotational force from the flywheel 127 to the reel zone 139 is cut off.

In addition, the pressing of the head substrate return lever 78 by the pressing piece 59 of the lever 57 rewinding by the release of the pressing of the rewinding button 16 is also released, and the lever 78 which rewinds the head substrate is a spring. (33) rotates clockwise in FIG. 24 centering on the point pin 35. As shown in FIG. For this reason, the press piece 81 of this lever 78 presses the edge of the lower side in FIG. 24 of the head board 82, and the head board 82 is guide-bar 83 and the roller 86 by this. ) Is guided by the U-shaped flaws (35) to be engaged and moves upward against the coil spring (87).

Therefore, the recording / playback head 88 supported on the head substrate 82 enters into the cassette 5 from the front opening of the cassette 5 and again contacts the magnetic tape.

In addition, the pinch roller lever 90 in which the thrust movement is prevented by the long hole 96 of the head substrate 82 is also capable of thrust movement. The pinch roller lever 90 rotates counterclockwise around the pin 89 by the coil coil spring 93, and the pinch roller 95 supported by the lever 90 again applies the magnetic tape. Capstan 130 is pressed against. Since the capstan 130 is rotationally driven by the motor 125 through the motor pulley 126, the belt 128, and the flywheel 127, the magnetic tape compressed by the capstan 130 may not travel. Will resume. In addition, when the pinch roller lever 90 rotates, the pressing piece 97 of the lever 90 moves upward in FIG. 24, and thus the pressing piece prevents the rotating movement through the pin 162. The idler switching lever 159 was tensioned by the coil spring 160 via the idler support lever 157, rotated clockwise in FIG. 24 around the pin 161, and the idler switching lever 159. And the idler support lever 157 connected through the pin 159 are moved upward in FIG. 24, and the make-up idler 156 supported by the lever 157 is again a flywheel 127. The friction wheel 135 is contacted with the friction wheel 148 of the driving wheel 146 of the rail stand 138 on the winding side. Therefore, the rotation of the flywheel 127 is transmitted to the rail band 138 on the winding side through the take-up idler 156 and the driving wheel 146, and the magnetic tape that travels is engaged with the rail band 138. It is wound by (195) and a reproduction mode is exhibited.

In this case, the operation of the dual touch revue can be performed by releasing the recording mode immediately to the revue mode, and again by only operating the button 17 which rewinds the switching mode from the revue mode. In the case of reproducing the media immediately, it is possible to provide a tape recorder which is very convenient and has excellent operability.

While the present invention has been described based on the embodiments, the present invention is not limited to the above embodiments and various modifications are possible based on the technical matters of the present invention.

For example, the above embodiment applies the present invention to a small tape recorder, but the present invention can be applied to a recording / playback apparatus other than a tape recorder, for example, a VTR.

As described above, according to the present invention, a regeneration operation member capable of switching the device to a regeneration state by the throttle, and the regeneration operation member reciprocated by the reciprocation, and the device can be switched to the recording state. A recording operation member, a high-speed feed operation member in which the apparatus is switched to a high-speed transfer state by the movement, a fixing member for fixing the regeneration operation member at the moving position, and a fixing for fixing the recording operation member at the moving position. The member is provided, and when the high speed feed operation member is moved in the recording state, the fixing member holding the upper recording operation member at the reciprocating position moves to the fixed and released position, thereby releasing the fixing of the recording operation member. It is. Therefore, according to the present invention, since the reproduction operation member is also moved by the movement of the recording operation member, it is not necessary to move the reproduction operation member in order to bring the recording state, and one-touch recording is achieved. In addition, when the high speed feed operation members such as the fast button, the rewind button, etc. are moved together in the recording state, the holding member holding the recording operation member in the royal circumference moves to the unlocking position, Since the fixing is released and the regenerating operation member is kept fixed at the other fixing member in the reciprocating position, this results in a square mode of one-touch cue or one-touch revue. Moreover, according to the present invention, the operation of these one-touch queues and one-touch levers is achieved without installing special logic mechanisms or system controllers, and since these functions are enabled by relatively small parts, they are compact and have excellent operability. It is possible to provide a reproducing apparatus at a low cost.
