No rotational movement occurs between the two. Gears 243 and 244 are fitted to the fixed support shafts 241 and 242, respectively, so as to be rotatable and slidable in the axial direction.

Note that annular grooves 245 and 246 are formed on the outer circumferential surfaces of the post portions extending below these gears 243 and 244. Additionally, boss portions 247, 248 are formed above the gears 243, 244 in these holes. And this gear 24
Friction rings 249 and 250 are rotatably fitted to the outer peripheral surfaces of the post portions 247 and 248 of No. 3 and 244, respectively. The lower surfaces of these friction wheels 249, 250 are in contact with felts 251, 252 fixed to the upper surfaces of the gears 243, 244, and are configured to be frictionally driven by the gears 243, 244, respectively. . Also, these friction wheels 24
Engagement pins 253 and 254 are fixed to 9 and 250, respectively. Further, the reel shafts 9 and 10 are rotatably fitted to the upper end sides of the support shafts 241 and 242.

Two pairs of rings 255 and 256 are attached to these reel shafts 9 and 10, respectively, in the axial direction of the support shafts 241 and 242 to prevent them from sliding or falling off.
Engaging pawls 257 and 258 are formed on the outer peripheral surfaces of these reel shafts 9 and 10 for transmitting rotational force to the pair of reels housed in the force set 15, and their lower portions Gear portions 259 and 260 that engage with the engagement pins 253 and 254 of the friction rings 249 and 250 are formed in the respective friction rings 249 and 250. For this purpose, the rotational force of the friction wheels 249, 250 is transmitted to the pair of reels in the force set 15 via the engagement pins 253, 254, the gear portions 259, 260, and the engagement claws 257, 258. There is. Compression springs 261 and 262 are interposed between the reels 9 and 10 and the friction wheels 249 and 250, which respectively move the friction wheels 249 and 250 and the gears 243 and 244 to the support shafts 241 and 242. It is pressed downward in the axial direction.
In addition, a cap 26 is attached to the upper end of these reel shafts 9 and 10.

It is configured to rotate together with 0. Next, the drive switching mechanism for the reel shafts 9 and 10 will be explained. A pair of bent pieces 265 are formed on the auxiliary chassis 238, and a pair of pins 266 are formed on these bent pieces 265.
is being closely watched.

A pair of elongated holes 268 of a slide cam 267 fit into these pins 266, and the slide cam 267 is supported by the dirt so as to be slidable left and right in FIG. 2 relative to the auxiliary chassis 238. A pair of cam portions 269 and 270 are formed on this slide cam 267. c These cam portions 269 and 270 are respectively connected to the first reference surface 269a.
, 270a and second reference surfaces 269b, 270b. Further, a bending piece 271 is formed on this slide cam 267, and a tension spring 272 is tensioned between this bending piece 271 and the pin 266. In the figure, it is slidably biased to the right. Further, a bent pressed portion 273 is formed on the upper surface of the slide cam 267.
This pressed portion 273 is pressed by the bent piece 191 of the operation slider 188, so that the slide cam 267 is slidably operated. Further, a pair of pins 274 and 275 are implanted and fixed on the auxiliary chassis 238 in correspondence with the reel shafts 9 and 10, respectively.

These pins 274 and 275 have L-shaped operation pieces 276 and 277, respectively, in FIG.
is slidably supported in the axial direction. One tip of each of these operation pieces 276 and 277 is connected to the gear 2.
43 and 244 into annular grooves 245 and 246. Also, a pin 2 is attached to the other end of the operating pieces 276, 277.
80, 281 are fixed holes, and these pins 280,
281 are the cam portions 26 of the slide cam 267, respectively;
We are in contact with 9,270. Therefore, the slide cam 267
The operating pieces 276 and 277 are configured to be operated by the cam action of the respective holes.

For example, the pin 280 is connected to the cam portion 269 of the slide cam 267.
When the operation piece 276 is on the second reference plane 269b, the operation piece 276 is pushed down against the compression spring 278. Therefore, at this time, the gear 243 and the friction ring 249 are in a state of being moved downward along the support shaft 241 by the compression spring 261, and therefore the engagement pin 253 is separated from the gear portion 259 of the reel shaft 9. This means that the transmission of rotational force from the gear 243 to the reel shaft 9 is cut off. On the other hand, when the pin 280 is on the first reference surface 269a of the cam portion 269, the operating piece 276 is in the upper position, the gear 243 and the friction ring 249 are also in the upper position, and therefore the engagement pin 253 is in the upper position.
is engaged with the gear portion 259. Therefore, rotational force is transmitted from the gear 243 to the reel shaft 9. Next, the operation of the micro tape recorder with the above configuration will be explained. 1 Switching operation to playback mode To switch to playback mode, simply operate the playback button 3 to the right in the stop mode shown in FIG.

C. The reproduction mode shown in FIG. 3 can be obtained by 1. That is, when the playback button 3 is pushed to the right, the auxiliary slider 21 fixed to the playback button 3 also moves to the right. In addition, in the stop mode, the auxiliary slider 21 and the playback slider 26
and are mutually tensioned by the tension spring 25, so that the pins 23a and 23b implanted in the reproduction slider 26 come into contact with the left end of the elongated hole 22 of the auxiliary slider 21 in FIG. ing. Therefore, when the auxiliary slider 21 moves to the right, the reproduction slider 26 simultaneously moves to the right in FIG. 2 against the tension spring 31, and reaches the position shown in FIG. 3. During this movement of the playback slider 26, the locked portion 33 of the slider 26 overcomes the locking portion 43 of the lock lever 40, and the playback slider 26 is locked at this position. Further, as the reproduction slider 26 moves to the right, the protrusion 32 of the slider 26 comes into contact with the inclined part 137 at the tip of the intermediate slider 132, and presses the intermediate slider 132 upward in FIG. , the slider 132 stops forward movement at the position where the protruding portion 32 of the reproducing slider 26 abuts the flat portion 138 of the intermediate slider 132.

At this time, since the stepped portion of the intermediate slider 132 is engaged with the bent piece 176 of the lock slider 172, as the intermediate slider 132 moves forward, the lock slider 174 also moves forward against the tension spring 177. become. For this reason, as will be described later, the rewind button 7 and the fast forward button 6 are not locked in the playback mode, and pressing these buttons 6, 7 results in the so-called queue mode and review mode being activated. By moving the intermediate slider 132 upward, the pressing portion 139 of the slider 132 presses the pin 142 of the intermediate lever 140, and the lever 140 is rotated counterclockwise about the pin 141 in FIG. let

By rotating this intermediate lever 140, a pin 143 implanted in this lever 140 is moved to the switching slider 1.
This slider 144 is pressed by pressing the pressed portion 150 of 44.
is moved to the left in FIG. 2 against the tension spring 149. For this purpose, the slider 144 operates the operating section 154 via the leaf spring 152, thereby causing the switch 153 to
closes. Therefore, power is supplied to the recording/reproducing circuit and the motor 196 starts rotating. Further, due to the rightward movement of the reproduction slider 26, the head substrate is removed via a tension spring 97 stretched between one tip 96 of the head substrate pressing lever 94 and the slider 26. As shown in FIG. 8, the pressing lever 94 rotates counterclockwise around a pin 95, and the other end 98 of the lever 94 presses a pin 99 implanted in the head board 73.

For this reason, the head board 73 resists the tension spring 78 and
Move upward as shown. Therefore, the recording/reproducing head 80 supported on the head substrate 73 also moves forward.
The force enters the set 15 through the front opening 17 of the force set 15 and comes into contact with the magnetic tape 18. However, the head arm support stand 81 and the head arm 83 are attached to this head board 73.
The erasing head 87 supported through the head arm 83 has a pin 85 formed on the head arm 83 that connects to the recording nullifier 1.
Since the head arm 83 is in contact with the protrusion 118 of the head 12, the head arm 83 is prevented from moving forward, and as a result, the head arm 83 rotates counterclockwise around the pin 82 relative to the head board 73. Also, due to the forward movement of the head board 73, the gear switching lever 1
The pin 203 implanted on the head substrate 73 moves from the first reference plane 88 of the opening 86 of the head substrate 73 to the second l reference plane 89 side.

As a result, the gear switching lever 199 is rotated clockwise about the pin 200 by the tension spring 202 as shown in FIG. 8, and is supported by the lever 199 via the support shaft 204. The friction ring 207 is in contact with the flywheel 210>. For this reason, the rotation of the motor 196 is
, a belt 208, a pulley 206, a friction wheel 207 and a flywheel 210, and the capstan is driven to rotate.
Also, due to the forward movement of the head board 73,
The pressing portion 91 of the head board 73 presses the protruding portion 227 of the idler switching slider 221, and the idler switching slider 221 moves upward against the tension spring 228 as shown in FIG. Therefore, the protruding piece 225 of the auxiliary lever 216 is pulled via the tension spring 226, whereby the auxiliary lever 216 rotates counterclockwise about the pin 220 as shown in FIG. For this purpose, this auxiliary lever 2
The idler 213 supported by the idler 16 via the idler level 214 contacts the friction ring 212 and the gear 243. In addition, in this playback mode, the slide cam 267
is not operated and is in the same state as the stop mode.

That is, as shown in FIG.
80 is in contact with the first reference surface 269a of the cam portion 269 of the slide cam 267, and is in contact with the pin 2 of the operation piece 277.
81 is in contact with the second reference surface 270b of the cam portion 270. Therefore, the gear 243 is in the upper position, and the friction wheel 243 is in the upper position.
The 49-pin 253 is engaged with a gear portion 259 of the reel shaft 9. On the other hand, the gear 244 is turned to the t position, and the friction ring 25
The zero pin 254 is engaged with the gear portion 260 of the reel shaft 10, and the whirl shaft 10 is in a down state where it is not rotationally driven. Therefore, the rotation of the motor 196 is caused by the pulley 197,
Belt 208, pulley 206, friction ring 207, flywheel 210, friction ring 212, idler 213, gear 24
3. The information is transmitted to the reel shaft 9 on the take-up side via the friction ring 249, pin 253 and gear part 259, and the reel shaft 9
In the figure, it is driven one rotation clockwise.

Further, due to the forward movement of the reproduction slider 26, the pin 102 located in the notch 103 of the slider 26 is also pushed, so that the auxiliary lever 100 moves counterclockwise around the pin 101 as shown in FIG. Therefore, the implanted pin 109 on this lever 100 moves to the right as shown in FIG.
The pinch lever 104, which is related to another pedestal 107 implanted in the The pinch roller 106 attached to the tip of the lever 104 connects to the capstan 2 via the magnetic tape 16.
Contact with 11.

For this purpose, the magnetic tape 16 is driven to run at a predetermined speed. The playback mode is switched as described above, and the magnetic tape 16 in the force set 15 runs at the same speed as the surface speed of the capstan 211, and is sequentially fed out from the reel fitted with the feed-out reel shaft 10. , is wound onto the I-knoll fitted with the take-up reel shaft 9.

The recording/reproducing head 30, which is in sliding contact with the running magnetic tape 16, reproduces the audio signal recorded on the tape 16. Next, the operation of canceling the reproduction mode, that is, the operation of switching from the reproduction mode to the stop mode, will be explained with particular reference to FIG.

Canceling the playback mode is achieved by pushing the playback button 3 to the left in the playback mode shown in FIG.

That is, as shown in FIG. 9, the auxiliary slider 21 to which the regeneration button 3 is fixed has its elongated hole 22 connected to the pin 23a,
23b, it is slidably supported relative to the reproduction slider 26. As shown in FIG. 8, in the reproduction mode, the pins 23a and 23b
The playback slider 26 is in contact with the left end of the lock lever! -40. Therefore, play button 3
When pressed to the left, the auxiliary slider 21 and the playback button 3 move against the tension spring 25 as shown in FIG.
Move to the left relative to 6. For this purpose, use the auxiliary slider 2.
The protrusion 34 of No. 1 presses one end 50 of a rotor release lever 35 rotatably supported by the pin 123b, and moves the lever 35 clockwise around the pivot 23b as shown in FIG. Rotate it. For this purpose, this lever 35
The other end 38 presses the lock portion 43 of the lock lever 40.
1 pressure, and then move this lever 40 to the pin 41 as shown in FIG.
Rotate counterclockwise around the bow tension spring 42. Therefore, the engagement between the lock portion 43 of the lock lever 40 and the locked portion 33 of the regeneration slider 26 is released.The regeneration slider 26 is pulled by the backward movement tension spring 〉31 and moves backward to the left in FIG. do. By this backward movement of the reproduction slider 26, an operation opposite to the switching from the stop mode to the reproduction mode described above is performed, and the reproduction mode is switched to the stop mode. In other words, when the playback slider 26 moves back
! Is it an auxiliary reno? 100 moves back, and as a result, the pinch roller 106 moves back via the bottom lever 104 and is separated from the capstan 211. Further, since the head board pressing renoma 94 moves back, the head board 73 moves back by the tension spring 78, and the recording/reproducing bend 30 moves back to the cassette opening 5.
escape from the front opening 17. Also gear switching reno←19
9 moves back counterclockwise around the pin 200, and the friction wheel 2
07 and the flywheel 210 are spaced apart from each other. Further, the idler switching slider 221 is moved back by the tension spring 226, and therefore the idler 213 is moved back via the auxiliary level 216 and the idler lever 214, and the friction wheel 212 is moved back.
and leaves the gear 243. Further playback slider 26
Due to the backward movement of the intermediate slider 132, the intermediate slider 132 is moved backward by the tension spring 177 via the lock slider 174. Therefore, the intermediate lever 140 and the switching slider 144 are both moved back by the tension spring 149, the switch 153 is opened, and the power supply to the motor 196 and the recording/reproducing circuit is stopped. As described above, the reproduction mode shown in FIG. 8 is switched to the stop mode shown in FIG. 2. cormorant
Operation of switching to recording mode To switch to recording mode, press the play button 3 to the right while keeping the record button 4 pressed in the stop mode shown in FIG.

By doing this, the recording mode shown in FIG. 10 is obtained. Furthermore, when this recording button 4 is pressed in the playback mode shown in FIG. 8, the locked part 51 of the recording button 4 is connected to the chassis. It abuts on the lower side of the provided lock portion 51a in FIG. Therefore, the recording button 4 does not move completely forward, and the recording button 4 is not locked. For this reason, even if the recording button 4 is operated in the playback mode, it is not possible to switch to the recording mode. On the other hand, when the playback button 3 is pressed to the right while the record button 4 is held down, the locked portion 51 of the record button 4 is locked by a lock portion 51a connected to the chassis.

Further, by pressing the playback button 3 to the right, the locked portion 33 of the playback slider 26 is locked by the locking portion 43 of the lock lever 40, similar to the switching operation outside the playback mode. As the recording button 4 moves forward, the pressing part 52 of the recording button 4 presses the pressed part 56 of the press recorder L53 supported by the auxiliary slider 21, and
-53 is rotated counterclockwise about the pin 54 as shown in FIG.

For this purpose, the pin 55 inserted into the recording slider 112 is located at the edge 11 of the recording slider 112 in FIG.
7 to move the nullider 112 upwardly in FIG. 10 against the tension spring 116. Therefore, the protrusion 118 of this slider 112 also moves upward. For this reason, the head arm 83, whose rotation was restricted by the protruding portion 118 via the pin 85, moves to the first position around the hibutsu 82.
As shown in FIG.
7 enters into the cassette 15 through the front opening 17 of the cassette 15 and comes into sliding contact with the magnetic tape 16. Further, when the recording slider 112 moves upward, the right side portion 120 of this slider 112 is attached to the bending piece 15 fixed to the rewind button 7.
Move to the position opposite 8.

At the same time, the protrusion 121 of this slider 112 is connected to the fast forward button 6.
Move to a position facing the For this reason, the rewind button 7 or the fast forward button 6 cannot be pressed in this recording mode. That is, in the recording mode, even if the rewind button 7 or the fast forward button 6 is pressed by mistake, the system is configured so that the mode cannot be switched to the rewind mode or the fast forward mode. Further, by the forward movement of the recording button 4, the recording button 4 presses a fish-shaped lever 57 supported by a switching slider 58, so that the lever 57 is rotated around a pin 59 as shown in FIG. It is rotated against the coil spring 60 in the correction direction.

For this reason, the pressed portion 61 of the fish-shaped lever 57 faces the pin 30 fixed to the reproduction slider 26. In this state, the reproduction slider 26 moves to the right as shown in FIG. 10, so the pin 30 presses the pressed portion 61 of the fish-shaped lever 57 and moves this lever 57 to the right. Since this fish-shaped lever 57 is supported by a pin 59 fixed to the switching slider 58, movement of this lever 57 causes the switching slider 58 to move to the right against the tension spring 70. Therefore, the operating piece 68 of the switch 67, which is associated with the switching slider 58 via the leaf spring 60, is operated to switch the circuit switching switch 67, and the recording/reproducing circuit changes from the playable state to the recordable state. Change. Further, at the same time as switching to the playback mode by moving the playback slider 26 to the right, the intermediate slider 13
2. The switch 153 is closed via the intermediate lever 140 and the switching slider 144. Further, the forward rotation of the head substrate pressing lever 94 causes the head substrate 73 to move forward, and in conjunction with this, the gear switching lever 199 rotates clockwise so that the friction ring 207 and the flywheel 210 come into contact with each other. Airad 213 contacts friction ring 212 and gear 243.
Furthermore, the pinch curler 106 comes into contact with the capstan 211 via the auxiliary lever 100. As described above, the stop mode is switched to the recording mode, the magnetic tape 16 is driven to run at a predetermined speed, and a predetermined audio signal is recorded on the magnetic tape 76 by the recording/reproducing head. . If the break-off claw 18 (see Fig. 1) for preventing accidental erasure of the record set 15 is broken off, the detection lever 134 rotates to the position shown by the imaginary line in Fig. 10 and enters the recording mode. This prevents the switching operation.

In conjunction with the forward movement of the recording button 4, the recording slider 112
moves forward, so that the pin 122 on this slider 112
also move. For this purpose, the coil spring 12 of the detection lever 124
6, forward rotation in the counterclockwise direction about the pin 125 in FIG. 10 is permitted. Since the force set 15 does not have the break-off pawl 18, the detection part 127 of the lever 124 enters the force set 15, and the step part 12 of this lever 124
9 makes contact with the contact portion 123 of the recording slider 112. Therefore, in this state, the recording slider 112 is prevented from moving further forward, and switching to the recording mode is no longer possible. Note that the operation for canceling the recording mode, that is, the operation for switching from the recording mode to the stop mode, is performed in substantially the same manner as the operation for canceling the playback mode shown in FIG.

That is, the regeneration button 3 is moved back to the left in FIG. 10, the auxiliary slider 21 is moved to the left with respect to the regeneration slider 26, and the lock release lever 35 is moved clockwise in FIG. 9 around the pin 23b. As a result, the lock lever 40 is rotated counterclockwise in FIG. let By this backward movement of the playback slider 26, the record button 4 moves to the left, and the lock part 51 and head link part 5 of the record button 4 are moved to the left.
The engagement with 1a is released.

For this purpose, the recording slider 112 has a tension spring 11 for double movement.
It is pulled by 6 and moves back. For this purpose, the head arm 83
The erase head 87 is rotated counterclockwise around the pin 82 in FIG. Furthermore, when the recording button 4 is released from the recording button 4, the fish-shaped lever 57 is rotated counterclockwise in FIG. 10 around the pin 59 by the coil spring 60. The pressed portion 6 of this lever 57
The contact between 1 and pinot 30 is released. Therefore, a switching slider 58 supporting this lever 57 via a pin 59
is moved back to the left in FIG. 10 by a tension spring 70 for back movement. As a result, this slider 58 and leaf spring 6
The associated switch 67 via 6 is switched, and the recording/reproducing circuit is switched from the recordable state to the playbackable state. It should be noted that the backward movement of the reproduction slider 26 other than those described above is the same as the case of switching from the reproduction mode to the stop mode.

3 Switching to Rewind Mode The rewind mode is obtained by pressing the rewind button 7 in the stop mode shown in FIG.

That is, when the rewind button 7 is pressed, the locked portion 161 of the rewind slider 157 pushes up the lock portion 178 of the lock slider 174, as shown in FIG. And lock part 1
78 relatively over the locked portion 161, the lock slider 174 is moved back by the tension spring 177, and the lock portion 178 of this slider 174 moves over the rewinding slider 15.
The rewinding slider 157 engages with the locked portion 161 of No.7.
is locked. Further, as the rewinding slider 157 moves forward, the projection 166 of the slider 157 presses the pin 164 of the operating lever 163.
rotates counterclockwise around pin 148 as shown in FIG.

For this purpose, the pressed portion 150 of the switching slider 144 is pressed by the pin 164, and the slider 144 is pressed by the tension spring 1.
49 to the left as shown in FIG. 11 to close a switch 153 which is associated with this slider 144 via a leaf spring 152. For this reason, the motor 196 starts rotating, and power is also supplied to the recording/reproducing circuit.
Further, as the operating lever 163 rotates, the thick pin 165 installed on the lower side of the lever 163 presses the pressed portion 190 of the operating slider 188.

Therefore, the operation slider 138 moves to the left against the tension spring 192, and the bent piece 191 of the slider 188 presses the pressed portion 273 of the slide cam 267. Therefore, the slide cam 267 changes from the state shown in FIG. 6 to the state shown in FIG. 12. That is, as shown in FIG.
contacts the reference surface 270a. For this purpose, the operating piece 276
moves downward along pin 274 against compression spring 278. Then, the gear 243 equipped with the annular groove 245 with which the tip of the operating piece 276 is engaged moves downward along the support shaft 241, and along with this, the friction ring 249 is also moved downward by the compression spring 261. Move to. For this purpose, the friction wheel 24
The pin 253 implanted in the gear part 2 of the roll shaft 9
59 is released, and rotational force is no longer transmitted from the gear 243 to the roll shaft 9. One operation piece 277
moves upward, so the gear 244 and the friction ring 250 move upward along the support shaft 242, and the pin 254 implanted in the friction ring 250 and the gear part 260 engage, and the rotation of the gear 244 This is transmitted to the reel shaft 10 via the friction ring 250, and the reel shaft 10 is in a state where it can be rotated one rotation counterclockwise in FIG. 11.

Moreover, when switching to the rewind mode, the head board 73 is not moved forward, but remains in the backward movement position.

Therefore, the gear switching lever 199 also does not rotate, and this lever 1
Gear 205 supported by 99 is engaged with carrier 231 . For this purpose, the rotation of the motor 196 is controlled by the pulley 197, the (sub)reto 208, and the pulley 197. J2O6, gear 2
05, the signal is transmitted to the reel shaft 10 via the carrier 231, the gear 244, the friction ring 250, the engagement pin 254, and the gear portion 260 of the reel shaft 10. The magnetic tape is therefore wound at high speed onto the delivery reel in the force set 15 which engages the reel shaft 10, and the rewind mode is established. Next, the operation of canceling the rewind mode, that is, the operation of switching from the rewind mode to the stop mode will be explained with reference to FIG.

To cancel this rewind mode, the playback button 3 may be pressed and moved further to the left from the stop position, as shown in FIG.

In this rewinding heat state, the playback button 3 remains in the stop mode state, and the pins 23a and 23b supporting the auxiliary slider 21 by the tension spring 25 are elongated as shown in FIG. It is in contact with the left end of the hole 22. In this state, if you push the auxiliary slider 21 to the left via the playback button 3 and move it, this auxiliary slider 2
1 moves relative to the reproduction slider 26 against the tension spring 25, and the protrusion 34 of the auxiliary slider 21 presses one end 36 of the lock release lever -35. For this reason, the lock release lever 35 rotates clockwise around the pin 23b implanted in the regeneration slider 26, and the lever 3
The pin 39 of No. 5 presses the mouth lever 40. Therefore, the lock lever 40 rotates counterclockwise about the pin 11 as shown in FIG. The pressing part 44 at the tip of this lever 40 is the pressed part 1 of the lock slider 174.
80 to move this slider 174 upward in FIG. For this purpose, this lock slider 1
The rotter portion 178 of 74 is separated from the locked portion 161 of the rewinding slider 157, whereby the rewinding slider 15
7 will be unlocked. Note that canceling the rotation of the rewind button 7 can also be achieved by operating the playback button 3 in the rewind mode to switch to the playback mode.

That is, when the playback button 3 is operated, the protrusion 32 of the playback slider 26 moves the intermediate slider 132 forward, but at this time, the bent piece 176 of the lock slider 174 engages with the stepped portion 136 of the intermediate slider 132. Therefore, the lock slider 174 also moves forward and the rewind button 7 is unlocked. Moreover, the rewinding slider 157 is connected to the tension spring 14.
9 and tension spring 192 in the backward movement direction via the operating lever 163.

It moves back by releasing the tsuku. Along with this, the switch 153 is opened by the backward movement of the switching slider 144, and the power supply to the motor 196 and the recording/reproducing circuit is cut off. Furthermore, as the rewinding slider 157 moves back and the rolling slider 188 moves back, the slide cam 267 is also moved back by the tension spring 272. For this purpose, operation piece 2
76 and 277 are switched from the state shown in FIG. 12 to state 5 not shown in FIG. break away. As a result, the reel shaft 9 on the winding side can be rotated again. 04 Switching operation to fast-forward mode 3 Switching to fast-forward mode can be done by pressing the fast-forward button 6 in the stop mode shown in FIG. . By doing this, the mode is switched from the stop mode to the fast forward mode shown in FIG. So, when you press fast forward button 6, this button 6 is stuck.
↓The fast-forward slider 167 moves forward, and the fast-forward slider 16
The opening and hook portion 171 of No. 7 pushes up the lock slider 174 and the rotor portion 179. Then, when the printer section 179 relatively climbs over the rotatable section 171, the lock slider 17
4 is moved back by a tension spring 177, and this slider 17
The rotor portion 179 of No. 4 engages with the locked portion 171 of the fast-forward slider 167, and the fast-forward slider 167 is locked. Further, due to the forward movement of this slider 167, the bent piece 172 of this slider 167 bends over the protruding piece 1 of the switching slider 144.
51 and pull this switching slider 144 to the tension spring 149.
14, and move it to the left against the

As a result, the changeover switch 153 is operated and closed, and power is supplied to the motor 196 and the recording/reproducing circuit. It should be noted that when switching to this fast forward mode (in other words, as in the case of switching to the rewind mode), the head board 73 is not moved forward, so the gear switching lever 199 also does not rotate. Gear 205 supported at 199 is engaged with carrier 231 .

Furthermore, when switching to this singing feed mode, the slide cam 267 is not operated, and as shown in FIG.
3 is engaged with the gear portion 259 of the reel shaft 9, and the pin 254 is disengaged from the gear portion 260 of the reel shaft 10. ．． For this reason, the rotation of the motor 196 is as follows:
8, Pui IJ2O6, gear 205, carrier 231. It is transmitted to the reel shaft 9 on the winding side via the gear 244, the gear 243, the friction ring 249, the pin 253, and the gear part 259. Therefore, the cassette opening 5 engaged with the tail → 11119
The magnetic tape 16 is wound at high speed onto a take-up reel inside the
A fast forward mode appears. Next, the release operation of the fast forward remote, that is, the switching operation from the fast forward mode to the stop mobile mode will be explained. This fast-forward mode can be canceled by moving the playback button 3 further to the left from the stop position in the same way as the rewind mode cancellation operation (see FIG. 13).
That is, by moving the ⅙ button 3 and moving the auxiliary slider 21 relative to the playback slider 26, the o vine release lever 3 is moved.
5 to move the lock slider 174 forward (against the tension spring 177) via the rotary lever 40 to unlock the fast-forward slider 167. Along with this, the switching slider 44 is moved back by the tension spring 149. For this reason, the switch 153 is switched open and the power supply to the motor 196 and the recording/reproduction/regeneration is cut off. 5. Switching to review mode Switching to review mode shown in FIG. 15 is performed by pressing the rewind button 7 in the playback mode (see FIG. 8). Obtained by manipulating.

Furthermore, this. - The review mode is for rewinding the magnetic tape 16 by a small amount in the playback mode. Therefore, in review mode 1, the device remains in this mode and is not locked. That is, when the rewind button 7 is pressed in the playback mode state, the rewind slider 157, which is biased to slide in the backward movement direction via the operation slider 138 and the operation lever 163 by the tension spring 192, is moved by the tension spring 192. It moves to the left G in FIG. 15 against this.

At this time, the lock slider 174 is pushed by the stepped portion 136 of the intermediate slider 132 that is moving forward and is moving upward in FIG. This slider 157 is not locked. As the rewinding slider 157 moves forward, the protruding piece 166 of the slider 157 moves against the pin 16 of the operating lever 163.
4 and rotates the lever 163 counterclockwise in FIG. 15 about the pin 148.

For this purpose, the pin 165 of this operating lever 163 presses the operating slider 188 and moves this slider 188 in the vertical direction in FIG. 15 against the tension spring 192. Therefore, the bent piece 191 of this slider 188 presses the pressed portion 273 of the slide cam 267 and the slide cam 26
7 to the left in FIG. For this purpose, the operation pieces 276 and 277 are operated, respectively, and the reel shaft 9,
10 is a pin 253 fixed to the friction ring 249, which changes from the state shown in FIG. 6 to the state shown in FIG. 12, as in the case of switching to the rewind mode.
is detached from the gear portion 259 of the reel shaft 9, and the friction ring 2
A pin 254 fixed to the reel shaft 10 engages with a gear portion 260 of the reel shaft 10. Therefore, the gear 243 is connected to the reel shaft 9.
The rotation of the gear 244 is not transmitted to the reel shaft 10.
The rotation is now in a state where it can be transmitted. Further, due to the forward movement of the rewinding slider 157, the pressing portion 162 of the slider 157 is pressed against the pressed portion 18 of the head board push-back lever 181.
4 to rotate this lever 181 counterclockwise in FIG. 15 about the pin 182. For this reason, the pressing portion 183 of this lever 181 is
In Figure 5, press the edge of the top end. Accordingly, the head board 73 moves downwardly in FIG. 15 against the tension spring 31 associated with the head board 73 via the pin 99 and the head board pressing lever 94. Head board 7
3 moves back, the pressing part 91 of the head board 73 separates from the protruding part 227 of the idler switching slider 221, and the idler switching slider 221 moves back by the tension spring 228. As a result, the auxiliary lever 216 is moved back to the pin position. The idler 213, which is supported by the lever 216 via the idler lever 214, is rotated clockwise in FIG.

Further, due to the backward movement of the head board 73, the bent piece 73a formed integrally with the head board 73 presses the pressed portion 104a of the pinch lever 104, and this lever 1
04 against the tension spring 108 in FIG.
Rotate counterclockwise around 01.

As a result, the pinch roller 106 is connected to the capstan 211.
This pinch roller 106 and capstan 2
11 is released. Due to the backward movement of the head board 73, the pin 203 of the gear switching lever 199 is moved from the second reference surface 89 side of the opening 86 of the head board 73. The pin 203 moves relatively toward the first reference surface 88 and is pressed by the first reference surface 88 .

Therefore, the gear switching lever 199 rotates around the pin 200 in the first position.
Rotates counterclockwise in Figure 5. For this reason, the friction wheel 207 supported by this lever 199 is separated from the flywheel 210, and the gear 205 also supported by the lever 199 meshes with the carrier 231. Therefore, the rotation of the motor 196 is River 97, Belt 208, Pui 1
j206, gear 205, carrier 231, gear 244,
The force is transmitted to the reel shaft 10 on the delivery side via the friction ring 250, pin 254 and gear portion 260, and the reel shaft 10 is driven counterclockwise in FIG. As a result, the feed-out magnetic tape 16 in the cassette opening 5 that is engaged with the reel shaft 10 is rewound, and the review mode is brought out. Note that in this review mode, the rewind button 7 is not locked as described above, so when the user releases his or her finger from the rewind button 7, the review mode is canceled.

In other words, the review mode is switched to the playback mode. In other words, when you release your finger from the rewind button 7, the rewind slider 157 to which this button 7 is fixed releases the tension spring 1.
92 to operate the slider 188 and the operating lever 16
It is returned via 3. And this rewind slider 15
As the operation slider 188 moves back together with the slide cam 7, the slide cam 267 also changes from the state shown in FIG. 12 to the state shown in FIG. As a result, the reel shaft 10 and the friction wheel 250 can be driven to rotate.
The transmission of rotational force between the two ends is cut off. Further, due to the backward movement of the rewinding slider 157, the pressing force on the head board push-back lever 181 is also released.
returns to the forward position.

Along with this, gear switching Leno? 199 also rotates and gear 20
5 is separated from the carrier 231, and the friction ring 207 comes into contact with the flywheel 210. Further, as the head board 73 returns to its forward position, the idler switching 7 rider 221 moves forward, and the auxiliary lever 216 moves forward, causing the idler 213 to move forward.
comes into contact with the friction wheel 212 and the gear 243 to enter the regeneration mode, and the signal recorded on the magnetic tape 16 in the portion rewound by the repeater operation is reproduced again. 6 Switching operation to queue mode FIG. 16 shows the queue mode.

Switching to the queue mode is performed by pressing the fast forward button 6 in the playback mode (see FIG. 8). Note that this cue mode is used when the magnetic tape 16 is used in the playback mode.
Therefore, in this cue mode, it remains in this mode and is not locked. That is, as shown in FIG. 16, when the fast-forward button 6 is pressed in the playback state, the fast-forward slider 167 moves forward together with the button 6 against the tension spring 170 for backward movement.

At this time, the lock slider 174 has already been moved forward, so the fast-forward slider 167 is not locked, as in the review mode. When this fast-forwarding slider 167 moves forward, this slider 1610) press section 1
73 is a pressed portion 185 of the head board push-back lever 181
Press this lever 181 to the first position around the pin 182.
It is rotated counterclockwise as shown in Figure 6.

Therefore, similarly to the switching operation to the review mode, the lever 181 pushes the head board 73 and causes it to move back. This backward movement of the head board 73 causes the pressing portion 9 of this board 73 to
1 is separated from the protrusion 227 of the idler switching slider 221, the idler 213 is moved away from the friction ring 212 and the gear 2.
Stay away from 43. At the same time, the gear switching lever 199 also rotates due to the backward movement of the head board 73, the friction ring 207 separates from the flywheel 210, the gear 205 meshes with the carrier 231, and the pinch roller 106 separates from the capstan 211. . Therefore, the rotation of the motor 196 is caused by the pulley 197, belt 208, pulley 206, gear 205, carrier 231, . This is transmitted to the reel shaft 9 via the gear 244, the gear 243, the friction ring 249, the pin 253, and the gear portion 259. The reel shaft 9 rotates clockwise at high speed in FIG. 16. For this reason, the magnetic tape 16 is wound at high speed on the take-up reel in the cassette 15 fitted with the reel shaft 9, and the queue mode is brought out.
As already mentioned, the fast-forward button 6 is not locked in this queue mode, so when you release your finger from the fast-forward button 6, the tension spring 170 of the fast-forward slider 167 causes it to move back. As a result, the pressing force on the head board push-back lever 181 is also released, so that the head board 73 returns to the forward movement position. In conjunction with this hole, the gear switching lever 199 is also actuated, the gear 205 is separated from the carrier 231, and the friction ring 207 comes into contact with the flywheel 210. Further, as the head board 73 returns to the forward position, the idler switching slider 221 moves forward, the auxiliary lever 216 rotates forward, the idler 213 comes into contact with the friction ring 212 and the gear 243, and enters the regeneration mode. Subsequently, the signals recorded on the magnetic tape 16 will be reproduced. Next, the features of the ultra-compact tape recorder described above are summarized as follows.

First, the playback button 3 and recording button 4 are provided on one side 2 of the tape recorder main body 1, and the fast forward button 6 and rewind button 7 are provided on the other side 5, so you can hold the main body 1 with one hand and use your thumb. You can perform various mode switching operations using your index finger.

Further, there is no need to provide various operation buttons, and so-called Pline N-operation is possible. In addition to the basic tape recorder operations such as playback, recording, rewinding, and fast forwarding, you can now also operate the review 1 and queue 1 functions.Additionally, new operation buttons have been added for the review 1 and queue 1 operations. Not yet.

In other words, if you press the rewind button 7 in the playback mode, you can get the review mode, and in the playback mode, you can press the fast forward button 6.
The configuration is such that the cue mode can be obtained by pressing .For this reason, the beginning of the magnetic tape 16 can be quickly and reliably found.Furthermore, in the recording mode, the forward movement of the recording slider 112 This slider 112
A right side portion 120 and a protrusion 121 respectively prevent the rewind button 7 and the fast forward button 6 from moving forward, thereby preventing switching to the review mode and queue mode.

Further, the unlocking operations of the fast forward button 6 and the rewind button 7 utilize the movement of the auxiliary slider 21 relative to the playback slider 26, which is related to the backward movement of the playback button 3. This is done by moving the lock slider 174 forward via the lock noma 46.

This reduces the number of operation buttons and makes operations more convenient. Note that unlocking of the fast forward button 6 and the rewind button 7 can also be realized by operating the playback button 3 in the fast forward mode or rewind mode to switch to the playback mode. That is, when the playback button 3 is operated, the protrusion 32 of the playback slider 26 moves the intermediate slider 132 forward, but at this time, the bent piece 176 of the lock slider 174 moves forward.
Since the lock slider 174 is engaged with the stepped portion 136 of the intermediate slider 132, the lock slider 174 also moves forward and the fast forward button 6 and rewind button 7 are unlocked. Also play button 3
The lock can be released by moving the regeneration button 3 in the backward movement direction, utilizing the movement of the auxiliary slider 21 relative to the regeneration slider 26, and moving the lock lever 40 backward with the lock release lever 35. It is becoming a reality.

For this reason, the number of operation buttons does not increase and it becomes possible to easily operate with one hand. Further, a recording button 4 is provided close to the playback button 3, and these operation buttons 3, 4
The directions of movement are perpendicular to each other.

Then, if you move only playback button 4, it becomes playback mode,
Further, when the playback button 3 is moved while the record button 4 is pressed, the recording mode is set. Therefore, it is possible to hold the tape recorder main body 1 with one hand and switch to the playback mode and the recording mode with one finger.
As explained above, according to the present invention, even if the operating member physically provided on the playback button is slid from the middle position to either the playback operation position or the high-speed feed release position, which are different directions, In either case, the lock plate for the high speed feed button is moved to the release position.

Therefore, high-speed forwarding modes such as rewinding and fast forwarding can be canceled by operating the playback button. Therefore, compared to conventional devices that require at least one stop button, the number of operation buttons is reduced, and the operation device of the tape recorder can be configured simply.
It becomes possible to downsize the tape recorder. Furthermore, as described above, since the number of operation buttons is reduced, it is less likely that other operation buttons will be operated by mistake, and erroneous operations can be prevented. Furthermore, according to the present invention, as described above, the high-speed feed mode can also be canceled by moving the + button from the neutral position to the playback operation position, so it is possible to directly switch from the high-speed feed mode to the playback mode. This makes operation much easier.
