It is supported so that it can freely slide in the axial direction of c in the vertical direction in FIG. However, the above constant speed gear 1
9f is the constant speed gear 19f and the fourth gear of the reel shaft 19c.
A coiled spring 19b interposed between the spring receiver 19g provided at the lower end in the figure is normally biased upward in FIG. 4, and is in contact with the high speed gear 19m.

Here, the constant speed gear 19f is connected to the spring 19.
h, which meshes with the constant speed gear 39 in a state where it is urged upward in FIG. 4. In addition, in Figure 4,
Although the constant speed gear 191 and the constant speed gear 39 are separated from each other, this is drawn for convenience of drawing, and in reality, as shown in FIG.
are meshed with each other, and are now in a stopped state.

Then, in the stopped state as described above, for example, the playback operation panel 2
6 is operated, the switch slider 31 is slid in the direction of arrow E in FIG. 2 as described above, thereby turning on the power leaf switch and turning on the motor 2.
o is rotated clockwise in FIG. 2 (17-). Then motor 2 with

The rapid gear 41d is capable of meshing with the high speed gear 38.

Here, %Figure 5 shows the above-mentioned fast forward reverse drive gear 4.

This is a plan view of the fast-forwarding schiller 41b and the fast-forwarding gear 4Jd. That is, the fast forward lever 41
b is a hook portion 41e formed at the left end in FIG.
A coiled spring 4Jf is connected between the fast forward operation plate 29 and a hook portion 29h formed at the tip in the operation direction.
The fast forward operation panel 29 and the fast forward operation panel 29 are connected to each other.

Now, when the fast-forwarding operation plate 29 is in the non-operating position shown by the solid line in FIG. 5, the fast-forwarding shutter 4Jb is also rotated clockwise in the position shown by the solid line in FIG. being done. Here, when the fast-forward lever 41b is in the position shown by the solid line in FIG. 5, the fast-forward gear 41d
is spaced apart from the high speed gear 38. Therefore, in the recording and playback state described above and the rewinding state described later,
When the reel shaft 19a is rotated counterclockwise in FIG. 5 (clockwise during rewinding), the fast forward reverse drive gear 41 and the fast forward gear 41d are idly rotating.

Here, in the above-mentioned stopped state, move the fast forward operation plate 29 to the fifth position.
When the lock slider 2Jtl is pressed in the direction of arrow C in the figure, the fast forward operation plate 29 is at the position shown by the dotted line in FIG.
Suppose that C is locked.

Then, in conjunction with the operation of the fast-forward operation plate 29, the fast-forward lever 4Jb is rotated about the shaft 4ja'i in the direction counter to the hour hand in FIG. This fast forward Schilleper 4Jb wc
The rotation in the counterclockwise direction in FIG. 5 is performed until the fast feed gear 4Jd meshes with the high speed gear 38, which is the position shown by the dotted line in FIG.

Then, as mentioned above, the fast feed gear 4Jd becomes the high speed gear 3.

It is transmitted to the reel shaft 19a through the high speed gear 38, the fast feed power gear 41d, the fast forward drive gear 4, and the high speed gear 19, and the reel shaft 19e is rotated at high speed in the counterclockwise direction in FIG. Ru. On the other hand, when the fast-forward operation plate 29 is pressed, the protruding piece 2 formed on one side of the fast-forward operation plate 29
9b presses a retaining portion 24a'i formed at the rear end of the high-speed slider 24. For this reason, the high speed slider 24
becomes K when it is moved from the position shown by the solid line in FIG. 5 to the position shown by the dotted line in conjunction with the operation of the fast-forward operation panel 29. The movement of the high-speed slider 21-24 is achieved by rotating the head chassis 32 counterclockwise in FIG. 2 via the head chassis control lever 33 (see FIG. 2) as described above. , is used not only to separate the recording/reproducing head 14, pinch roller 15, etc. from the micro cassette tape, but also to resist the biasing force of the constant speed gear 19ft of the reel stand 19 and the spring 19b, which will be described in detail later. It is used for the action of separating from the constant speed gear 39 by sliding it downward in FIG. For this reason, as mentioned above, the reel shaft 19
A is rotated at high speed in the counterclockwise direction in FIG. 5, and the reel cap J9d is also rotated in the same direction, so that the micro cassette tape is run in a fast forward state.

Next, the reel stand 18, which serves as the winding side of the microcassette tape during rewinding, will be described. That is, as shown in FIG. 4 again, the bearing 18b, which has a substantially cylindrical shape and has a flange xa*t- at the lower end in FIG.
- The main chassis 111/c is fixedly provided, and the reel shaft 111c is rotatably loosely fitted into the bearing 22- holder 18b.
Ru. In the upper part of this reel shaft 18c in FIG.
The reel cap 18d is fitted, and the lower middle part of FIG.
A high speed gear 18e with a diameter of /4% is coaxially provided. Here, the above-mentioned one cap 18d and the high speed gear 1
8e each rotate integrally with the reel shaft 18a.

Further, one end portion of the rewinding lever 42 is rotatably supported by the bearing 18b. This rewind lever 42
A shaft 42a is implanted at the other end.
A large-diameter rewinding gear 42b, which is always in mesh with the high-speed gear 18, is rotatably supported at h. and,
This rewinding gear 42b is capable of meshing with the high speed gear 38.

Here, FIG. 6 shows the rewinding lever 42 and the rewinding gear 4jb in a plan view. That is,
The rewinding lever 42 has a coiled spring 42d between a hook portion 42a formed at the left end in FIG. 6 and a hook portion 281 formed at the tip of the rewinding operation plate 28 in the operating direction. (It will be busy if it is engaged), and is linked to the rewind operation plate 28.

Now, when the rewinding operation plate 28 is in the non-operating position shown by the solid line in FIG.
It has been rotated clockwise in the figure to the position shown by the solid line in the figure. Here, when the rewinding lever 42 is in the position shown by the solid line in FIG. 6, the rewinding gear 42b is separated from the high speed gear 38. Therefore, in the above-mentioned recording and playback states and fast-forwarding states, the reel shaft 18
When a is rotated counterclockwise in FIG.
2b is spinning idly.

Here, in the above-mentioned stopped state, move the rewind operation plate 28 to the sixth position.
Assume that the rewind operation plate 28 is locked to the lock slider 21 at the position shown by the dotted line in FIG. 6 by performing a suppressing operation in the direction of arrow C in the figure.

Then, in conjunction with the operation of the rewind operation plate 28, the rewind lever 42 is rotated counterclockwise in FIG. 6 about the bearing J8b'i. The sixth rewind lever 42
Rotation counterclockwise in the figure brings the rewinding gear 42b to a position where it meshes with the high-speed gear 38, which is the position shown by the dotted line in FIG.

Then, as described above, the rewind gear 42b is connected to the high speed gear 3.
8, the rotational force of the motor 20 is transmitted to the flywheel 17, which rotates counterclockwise in FIG.
0 rotational force is applied to the capstan gear 36. Drive gear 37. It is transmitted to the reel shaft 18c via the high-speed gear 38, the rewinding gear 4Jb, and the high-speed gear 18e, and the reel shaft 18c is rotated at high speed clockwise in FIG. 6.

On the other hand, when the rewinding operation plate 28 is pressed, the protruding piece 28b formed on one side of the rewinding operation plate 28
A retaining portion 2d formed at the rear end of the high-speed slider 24

The head chassis 32 is rotated counterclockwise in FIG. It is slid downward in FIG. 4 against the biasing force 19h and is separated from the constant speed gear 39. Then, as described above, the reel shaft 18e is rotated at high speed in the clockwise direction in FIG. 6, the reel cap lad is also rotated in the same direction, and the micro cassette tape is run here in a rewound state. .

When the stop operation plate 27 is operated in each of the playback, recording, fast forwarding, and rewinding states as explained above, it is locked by the lock slider 21 at the operation position one step earlier as described above. Recording operation board 25. Playback operation board 26
The locks of the one-rewind operation plate 28 and the fast-forward operation plate 29 are released, and the respective operation plates 25, 26, 28, and 29 are returned to their non-operating positions. Therefore, the switch slider 31 is also returned in the direction of arrow C in FIG. 6, the power leaf switch is turned off, and the rotation of the motor 20 is stopped. Then, the mechanism section is returned to the above-mentioned stopped state, and tape running is stopped. Note that when changing from the fast forward and rewind states to the stop state, the high speed slider 24 is returned to the upper position in FIGS. 5 and 6.
The constant speed gear 19f of the reel stand 19 is slid upward in FIG. 4 by the biasing force of the spring 19b, and returned to a state in which it meshes with the constant speed gear S9.

Next, in conjunction with the movement of the high-speed slider 24 in the direction of arrow C in FIGS. 5 and 6, the constant speed gear 19ff of the reel stand 19 moves downward in FIG. A mechanism for sliding the fixed speed gear 39 and separating it from the constant speed gear 39 will be explained. However, since this mechanism is related to the stop operation plate 27 and the temporary stop operation plate 30, the explanation will include them. That is, as shown in FIG. 7, a protruding piece 271L is formed on one side of the stop operation plate 27. As shown in FIG. This projecting piece 27a is a locking piece 43a formed on one side of the gear control slider 43, which is supported by the main chassis 11 so as to be slidable in the direction of arrow C in FIG. It is located above. Further, the gear control slider 43 is biased in the direction of the arrow in FIG. 7 by a spring (not shown).

On the other hand, a protruding piece 3 is provided on one side of the temporary stop operation plate 30.
0a is formed. This protruding piece 30& is the seventh part of the retaining part 24a formed at the rear end of the high-speed slider 24.
It is located at the top in the figure. In addition, this high-speed slider 24
The retaining portion 24e is located above the locking piece 4Jb in FIG. 7 extending from the lower part of the gear control slider 43 in FIG. Furthermore, a drive piece 43o is formed on the side of the gear control slider 43. This drive piece 43
As shown in FIG. 8, a is opposed to one end 44h of the gear control lever 44, which has a curved side surface.

The gear control lever 44 has a corner portion rotatably supported by a shaft 44b fixed to the main chassis 11. Further, the other end portion 44 of the gear control lever 44
c is in contact with the upper surface of the constant speed gear 191 of the reel stand 19 in FIG.

Now, assuming that the micro cassette tape recorder is in the above-mentioned playback state, as shown in FIG. 9(a)K,
Assume that the stop operation plate 27 is operated to suppress it. Then, the protruding piece 27m of the stop operation plate 27 comes into contact with the locking piece 4s* of the gear control slider 43, and the locking piece 43*f: FIG.
) to suppress in the middle and downward direction. For this reason, the gear control slider 43
is slid downward in FIG. 9 (IL), and its drive piece 4
3a is a gear control lever 4 as shown in FIG. 9(b).
4, and the one end 441 is touched by the ninth
Figure (b) Press in the direction of the middle seat. Therefore, the gear control lever 44 is rotated 29- in the middle clockwise direction as shown in FIG. The constant speed gear 19f is disengaged from the constant speed gear 39 by sliding it in the middle downward direction. Note that when the suppressing operation of the stop operation plate 27 is stopped, the stop operation plate 27 is returned to the upper position in FIG. is spring 19
Of course, it is slid upward in FIG. 9(b) by the biasing force of h, and is engaged with the constant speed gear 39.

Further, the operation of separating the constant speed gear 19 ft from the constant speed gear 39 in conjunction with the operation of the stop operation plate 27 as described above works in the same way when the micro cassette tape recorder is in the recording state. .

Further, suppose that the micro cassette tape recorder is in the playback state and the pause operation plate 30 is operated to suppress, as shown in FIG. 10(a). Then, as mentioned above, the temporary stop operation plate SO is moved to the position shown in FIG.
a) It is locked in the operating position shown by K. At this time, the protruding piece 30a of the temporary stop operation plate 30 presses the engaging portion 24at of the high-speed slider 24 downward in FIG. 10(a).
A high-speed slider 24 operates the fast forward and rewind operation plate z9.
In the same way as when operating z8, it is slid downward in FIG. 10(a). Therefore, the retaining portion 24c of the high-speed slider 24 locks the locking piece 43b of the gear control slider 43 at the tenth position.
Pushing downward in the figure, the gear control slider 43 eventually moves to the 10th position.
It slides downward in the middle of Figure (a). Therefore,
As mentioned earlier, as shown in FIG. 10(b), the gear control lever 44 is rotated clockwise in the middle of FIG. It is slid and removed from the constant speed gear 39. Therefore, the rotational force of the constant speed gear 390 is no longer transmitted to the reel shaft 19eK via the constant speed gear 191, so that the running of the micro cassette tape in the reproducing state can be temporarily stopped.

When the temporary stop operation plate 30t is pressed again at the operation position shown in FIG. 10(a), the temporary stop operation plate 30 is returned to the lower position in FIG. and the gear control slider 43 are also returned in the same direction. Therefore, the constant speed gear 19f is meshed with the rotating constant speed gear 39, and the micro cassette tape is again run in the playing state.

Here, as is clear from the above explanation, the high-speed slider 24 moves downward in FIG. The constant speed gear 19 ft functions to be slid and separated from the constant speed gear 39 via the gear control slider 43 and the gear control lever 44.

Furthermore, the above-mentioned pause operation works in the same way when the microcassette tape recorder is in the recording state.

In particular, as explained in FIGS. 9(a) and 9(b), we will explain how to disengage the constant speed gear 19f from the constant speed gear 39 in conjunction with the operation of the stop operation plate 27. do. That is, for example, if the micro cassette tape recorder is in the playback state and the stop operation panel 27 is operated, the playback operation panel 2
6 is returned to the non-operating position, and in conjunction with this, the power leaf switch is turned off, the rotation of the motor 20 is stopped, and the running of the microcassette tape is stopped. However, even if the power leaf switch is turned off and the power supply to the motor 20 is cut off, the flywheel 17 continues to rotate for a short time due to its busy nature.

The constant speed gear 39 is connected to the flywheel 17.
Since it rotates when zero rotational force is transmitted, if the constant speed gear 39 and the constant speed gear 19f are meshed even when the stop operation plate 27 is operated, the flywheel 11
The rotational force due to this quality is transmitted to the constant speed gear 19fIC. For this reason, the reel axis JJilc33
- Since the micro cassette tape is rotated by an amount corresponding to the rotation caused by the flywheel 170, the running of the micro cassette tape is not stopped immediately when the stop operation plate 21 is operated, resulting in so-called tape flow. There's a problem.

However, as shown in FIGS. 9(a) and 9(b) K, in conjunction with the operation of the stop operation plate 27, the constant speed gear 19f
By separating the ft from the constant speed gear 39, it is possible to prevent the rotational force due to the penetration of the flywheel 170 from being transmitted to the constant speed gear 19fK. Therefore, the running of the microcassette tape is stopped immediately when the stop operation plate 2rt is operated, and it is possible to prevent the tape from flowing.

Further, the effect of preventing the tape from flowing is that when the micro cassette tape recorder is in the recording state, the stop operation plate 27
Of course, the same thing happens when you operate .

Next, the micro cassette tape recorder 34- is equipped with an automatic stop mechanism (hereinafter referred to as ASO) that automatically stops the micro cassette tape when it reaches the end in each of playback, recording, fast forwarding and rewinding states. The ASO mechanism will be described below. That is, to explain with reference to FIG. 3 and FIG. 11 described above, first, the ASO lever 22 has a mounting shaft 22b attached to the main chassis 11 inserted through its approximate center. It is rotatably supported. The ASO lever 22 has a protrusion 22a that protrudes downward in FIG. 3 from one end thereof as the biasing lever 39c! ′!
By being loosely fitted into a long hole 39e formed at one end, it is interlocked with the biasing lever 39c.

Further, a retaining portion 22a (see FIG. 11) is formed at the other end of the ASO lever J2, and comes into contact with the circumferential side of the eccentric cam portion 3rd formed on the upper surface of the driving gear 37 in FIG. ing. Therefore, due to the rotational force of the motor 20,
When the drive gear 37 is rotated clockwise in FIG. 11 and the high speed gear 38 and constant speed gear 39 are rotated in the same direction, the biasing lever 39a is also biased clockwise in FIG. be done. Therefore, the ASO lever 22 is also biased clockwise in FIG. 11 about the mounting shaft 22bf, and its retaining portion 22c is pressed against the circumferential surface of the eccentric cam portion J7d.

For this reason, the ASO lever 22Vi, the drive gear 37
, while the high-speed gear 38 and the constant-speed gear 39 are rotating, the mounting shaft 22 follows the circumferential surface of the eccentric cam portion J7d.
It performs a rocking motion centering on b.

On the other hand, at the upper end of the ASO lever 22 in FIG.
A protruding piece 2 formed at one end of the lock slider 21
A protrusion 22d is formed that can be fitted to the base 1a. When the ASO lever 22 is swinging as described above, the protrusion 22d moves away from and approaches the protrusion 21a of the lock slider 21;
It is configured such that it is not engaged with the protruding piece ffJa.

Further, the ASO lever 22 has a driven portion 22e formed near the protrusion 22d.

This driven portion 22m is capable of engaging with a curved driving portion 31e formed on the upper surface of the driving gear 37 in FIG. The driven portion 22 of the ASO lever 22
As described above, when the ASO lever 22 is in the swinging motion, e is always located on the inner circumferential side of the drive section 37 in FIG. 11 when the drive section 37 is passed. There is.

First, the automatic stop operation during playback will be described. That is, when the micro cassette Teso recorder is in the playback state, the playback operation plate 26 is locked to the lock slider 21 at the operation position, and the drive gear 37 is rotated by the rotational force of the motor 20 as shown in FIG. The high speed gear 38 and the constant speed gear 39 are rotated in the same direction. The reel shaft 19a is connected to the constant speed gear 19ft which is meshed with the constant speed gear 39.
is rotated, and the 37-ASO lever 22 is performing a swinging motion.

When the micro cassette tape reaches the end in such a playing state, the reel shaft 19e and the constant speed gear 1.9f
rotation is forcibly stopped.

Therefore, the constant speed gear 39 meshed with the constant speed gear 191
The zero rotation is also stopped, and the biasing force in the clockwise direction in FIG. 11 is no longer applied to the biasing lever 39c. Therefore, A.S.
The engaging portion 22c of the O-lever 22 is no longer pressed against the circumferential surface of the eccentric cam portion 3rd of the drive gear 37.

However, the driving gear 37 continues to be rotated clockwise in FIG. 11 by the rotational force of the motor 20. At this time, a surface is created between the high speed gear 88 and the constant speed gear 39 via the friction member 40 (see FIG. 3).

For this reason, the above person li! The O lever 22 has its retaining portion 2
2c is defined at the position pressed by the maximum diameter portion of the eccentric cam portion J7d of the drive gear 37, and thereafter the eccentric cam portion J7d
7d will no longer follow. When the lever 22 is in this position, when the drive gear 37 is further rotated clockwise in FIG. 11, the drive portion 37e is engaged with the driven portion 22. It is. In this case, the driven part 22e is the 11th part of the driving part 37e.
It is engaged on the outer peripheral side in the figure. For this reason, the ASO lever 22
By moving the driven portion 22 along the outer periphery of the driving portion 37e of the driving gear 37, the driven portion 22.
It is rotated counterclockwise in Figure 1.

At this time, the protrusion 22d of the ASO lever 22 presses the protrusion 21*ft of the lock slider 21, causing the lock slider 21 to slide in the direction of arrow E in FIG. Therefore, the regeneration operation plate 26 that has been locked to the lock slider 21 is unlocked, the regeneration operation plate 26 is returned to the non-operation position, and automatic stopping is performed here.

Further, it goes without saying that even when the microcassette tape reaches its end in the recording state, an automatic stop operation is performed in the same way as described above. However, in this case, the lock slider 21! When slid in the direction of the arrow in FIG. 11, both the recording operation board 25 and the playback operation board 26 are returned to their non-operating positions.

Next, before explaining automatic stopping operations during fast forwarding and rewinding, the limiter lever 37c will be explained. That is, this limiter lever 37c is
As shown in FIG. 11, it is formed into a substantially curved shape, and is rotatably supported by a shaft 37f implanted in the drive gear 37 at its substantially central portion. This limiter lever 37
A pair of protrusions 3Bam38b are formed at one end of the high-speed gear 38 at opposing positions across the shaft 31*f.
and a hook portion 31 that is selectively engaged with 38a and B8d.
g is formed. i, the limiter lever 31e
The spring 37b is engaged between the through hole 97h formed at the other end and the through hole 371 formed in the drive gear 37, so that the hook portion s'ig
is the protrusion above! jam, 38b or 38e, and is biased in the direction of engagement with B8d.

Now, as shown in Fig. 11, the limiter lever 3
The hook portion 37g of re is the protrusion 38*, 3 of the high speed gear 38.
Assume that the drive gear 37 is rotated clockwise in FIG. 11 by the rotation of the motor 20 while being engaged with the drive gear 8b.

Then, the rotational force of the drive gear 370 is applied to the limiter lever J7.
a to the high-speed gear 38, and this high-speed gear 3
8 is transmitted to the constant speed gear 39 via the friction member 4o.

Here, as described above, drive gear 37. When a predetermined load is applied to the constant speed gear 39 while the high speed gear 38 and the constant speed gear 39 are rotating integrally, the rotation of the constant speed gear 39 is stopped, but the high speed gear 38 continues to rotate completely. (This state is the state in which the tape has reached the end in the playback state described above.) When a load greater than the predetermined load is applied to the high-speed gear 38, its rotation is stopped. Ru. At this time,
Since the drive gear 37 is rotated clockwise in FIG. 11 by the rotational force of the motor 20, the hook portion svz of the limiter lever 37c is forcibly removed from the protrusions 38*, 3'8b. Then, the hook portion svg is the next protrusion 38a,
311dK is engaged, but it is forcibly disengaged again, and this operation is repeated thereafter, resulting in a situation in which the rotation of the high speed gear 38 is stopped and the rotation of the drive gear 370 is continued.

This state corresponds to the state in which the microcassette tape reaches the end in the fast forwarding and rewinding states described below. That is, by making the driving gear 37 and the high-speed gear S8 interlocked by the limiter lever 31e, and by interlocking the high-speed gear 38 and the constant-speed gear 39 by the friction member 40, the difference in the strength of the interlocking relationship can be made. The reason for this will be explained later.

When the micro cassette tape recorder is in the fast forward/rewind state, the fast forward/rewind operation plate 29 and the rewind operation plate 28 are locked to the lock slider 21 at the operating position. The drive gear 37 is rotated clockwise in FIG. 11 by the rotational force, and the high speed gear 38 and constant speed gear 39 are accordingly rotated in the same direction.

For this reason, the rapid traverse gear 41d meshed with the high speed gear 38
and the reel shaft 19em 1 via the rewinding gear 42b, etc.
8c are rotated, and the ASO lever 22
is performing a rocking motion.

When the micro cassette tape reaches the end in such fast forwarding and rewinding states, the rotation of the reel shaft 1Qal 180 is forcibly stopped.

Therefore, the rotation of the high speed gear 38 is stopped, and as described above, the rotation of the high speed gear 38 is stopped.

The drive gear 37 is in a rotating state.

Further, at this time, as the rotation of the high speed gear 38 is stopped, the rotation of the constant speed gear 390 is also stopped, and as described above, the biasing force of the button and biasing lever JjcK is no longer applied. For this reason, A
The driven portion 22m of the SO lever 22 is engaged with the driving portion 37e of the driving gear 37, and the lock slider 21 is slid in the direction of the arrow E in FIG. 11, as described above. Therefore, the fast-forward operation plate 29 and the rewind operation plate 28, which were locked to the 0x slider 21, are unlocked, and automatic stopping is performed.

Therefore, according to the ASO mechanism as described above, the high-speed gear 38. Constant speed gear 39 and bias lever 390t that transmit rotational force to reel shaft 19a during recording and playback
-1 Since it is arranged coaxially, it occupies less space, which contributes to the miniaturization of the micro cassette tape recorder, and it is also advantageous in terms of ease of assembly because it can be easily assembled into one unit. In addition, since both the high speed gear 38 and the constant speed gear 39 are rotated in the same direction, recording and playback are possible.

Reel shaft 19 e # 18 e during fast forwarding and rewinding
Since there is no need to take into account that the direction of rotation of the ASO mechanism changes, the structure of the ASO mechanism can be simplified accordingly, and its operation can be ensured. In addition, the high-speed gear 38 is connected to a reel shaft 190 * 18 e on the winding side of the micro cassette tape during fast forwarding and rewinding so as to be able to transmit rotational force, and supplies the microcassette tape during fast forwarding and rewinding. The reel shaft 18c is the side.

19o is unloaded, so that unnecessary pack tension is not applied to the microcassette tape during fast forwarding and rewinding (smooth tape running).

By the way, as mentioned earlier, the drive gear 31 and the high speed gear 3
8 are interlocked through the limiter lever 31c', and the high speed gear 38 and constant speed gear 39 are interlocked through the friction member 40f, so that the strength of the interlocking relationship is different. I will explain about it. That is, during fast forwarding and rewinding, the rotational force of the high speed gear 38 is applied to the reel shaft 19a,
18e, and is transmitted to constant speed gear 390 during recording and playback.
The rotational force will be transmitted to the reel shaft 19e. However, as is well known with ordinary tape recorders,
Since it is necessary to rotate the reel shaft 19aalBe at high speed during fast forwarding and rewinding, the driving force for rotating the reel shaft 19 c s 18 e f during fast forwarding and rewinding is as follows.
It has to be stronger than the driving force that rotates the reel shaft 19ef during recording and playback, and also,
If the driving force that rotates the reel shaft 19a during recording and playback is the same as the driving force that rotates the reel shaft 19ca I8e during fast forwarding and rewinding, the reel shaft 19e will be rotated with more force than necessary during recording and playback. Therefore, when the microcassette tape reaches its end, unnecessary tension is applied to the tape, damaging the tape (9) and is also undesirable in terms of power consumption.

Therefore, the driving gear 37 and the high-speed gear 38 are connected to each other through the +V46-Mitsutareper 37c, and the high-speed gear 38 and the constant-speed gear 39 are connected to the driving gear 37 and the high-speed gear S8 through the friction member 40. By establishing a linkage relationship that is at least a little weaker, the rotational driving force applied to the reel shaft 196hi8c during recording and playback, fast forwarding, and rewinding can be set to appropriate values. It is something that can be done.

Furthermore, as a means of interlocking the drive gear 32 and the high-speed gear 38, it is possible to interpose a friction member between the drive gear 37 and the high-speed gear 3B. Spring 38b, 39rl shown in the figure
In addition to this, a separate spring is required to press the high-speed gear S8 against the drive gear 37, and this spring must generate an urging force of about 10 times or more than the springs s and sb described above. In this case, it is impossible to differentiate the strengths of the two interlocking relationships, and the structure becomes complicated and is not practical.

Therefore, as shown in FIG. 11, the limiter lever 37
(by making the driving gear 37 and the high-speed gear 38 interlocked using the spring 37b, etc.)
It is possible to realize an interlocking relationship with a predetermined strength with a simple configuration, and it is extremely practical.

Next, the micro cassette tape recorder is provided with safety measures using the above-described ASO mechanism. This safety measure is for recording and playback.

If the cassette holder 13 is opened while the micro cassette chive is running in the fast forward and rewind states, the ASO mechanism automatically stops the micro cassette chive in the cab stance. This prevents the wire from getting wrapped around the wire or causing damage. That is, as shown in FIG. 12, the ASO lever 22 has a protruding piece 22f formed near the driven portion 22. The protruding piece 221 can be engaged with one end of the opening/closing detection lever 23. The opening/closing detection lever 23 is rotatably supported by a shaft 23a implanted in the main chassis 11 at a substantially central portion thereof. Further, the other end of the opening/closing detection lever 23 is formed with an inclined portion 23b that can engage with the tip 13a of the extending portion 13d extending from one of the clamping portions 13c of the cassette holder 13. .

The opening/closing detection lever 23 has a coiled spring between the locking portion JJ (+) formed between one end thereof and the shaft 28m and the protrusion JJd formed on the main chassis 11. 23 is engaged, one end of the opening/closing detection lever 23 is biased in a direction to engage with the protruding piece 22f of the ASO lever 22.

Here, as shown in FIG. 13(a), when the cassette holder 13 is in the closed state, the opening/closing detection lever 23 has a distal end 13. (a) Since it is pressed in the used direction,
The opening/closing detection lever 2S is rotated clockwise in FIG.
The ASO lever 22 is spaced apart from the protruding piece 22f of the SO lever 22, so that the ASO lever 22 can freely perform the swinging motion described above.

Furthermore, as shown in FIG. 13(b), when the opening/closing detection lever 23 is in the cassette holder 15-gH4 state, its tip 13 is separated from the inclined part 23b of the opening/closing detection lever 23. It is rotated counterclockwise in FIG. 12 by the biasing force of the spring 23. Therefore, one end of the opening/closing detection lever 23 is engaged with the protruding piece 22f of the ASO lever 22, and Ago1+-2
2 is rotated clockwise in FIG. At this time, AS
The O-lever 22 is configured such that its retaining portion 22a is defined at substantially the same position as the position pressed by the maximum diameter portion of the eccentric cam portion 3rd of the drive gear 31.

Here, it is assumed that the cassette holder/-x3f is now in the closed state and the playback operation plate 26 is locked to the lock slider 21 as shown in FIG. Then, as mentioned earlier, the drive gear 37 shifts to the first position.
When the ASO lever 22 is rotated clockwise in FIG. 2 and the micro cassette tape is running, the ASO lever 22 performs a rocking motion and is in a stable playback state.

Assume that the cassette holder 13 is opened in this reproduction state. Then, as described above, the first opening/closing detection lever 23 is rotated clockwise in FIG. It is rotated counterclockwise in the figure. Therefore, as shown in FIG.
7 is rotated clockwise in the figure, its driving portion 37 is engaged with the driven portion 22 of the ASO lever 22. Then, similarly to the automatic stop operation described above, the protrusion 22d of the ASO lever 22 engages with the protrusion 21* of the lock slider 21, causing the lock slider 21f to slide in the direction of the arrow E in FIG. Therefore, the playback operation plate 26 is returned to the non-operation position, the rotation of the motor 20 is stopped, and problems such as the microcassette tape being wrapped around the capstan 16 can be prevented.

In addition, the above-mentioned safety measures also apply to K when the cassette holder 13 is opened while the micro cassette tape recorder is in the recording, fast forwarding, and rewinding states.
Of course, it works in the same way.

Therefore, according to the above safety measures, since the ASO mechanism is used, when the cassette holder 13 is in the open state, the member for stopping the micro cassette tape recorder is the open/close detection lever 23. and a spring 23, the structure is extremely economical and organic, and can operate reliably.

Here, the above-mentioned recording, playback one rewind and fast forward operation panel 25
．． 16.28.29t - locks in the operating position and engages the stop operating plate 27 and the ASO lever 22 to lock each operating plate 1
15, 26, 28, and 29, is provided on the surface side of the main chassis 11, on the side facing the tumbler micro tape cassette, as shown in FIG. . For this reason, main chassis 1
It is possible to improve the degree of freedom in arranging various movable members, gears, etc. for running the tape, which are provided on the solid side of Fig. It is something. Further, the ASO lever 22. The opening/closing detection lever 23, the high-speed slider 24, etc. are also provided on the front side of the main chassis 11 in FIG. 1 for the same reason as mentioned above.

By the way, as is clear from FIG. 1, the lock slider 2J and the ASO lever 22. Open/close detection lever 2
3 and the high-speed slider 24 are arranged in the main chassis 11 near the reel stand 18.19 and between the imaginary line where the axis of the reel stand 18.19 is placed and the operating section 12, and the cassette holder 13. It is designed such that it is not placed near the base 18m of the base 18m. This is due to the shape of the cassette half of the Micro 53-tape cassette.

That is, as is well known, the cassette half is formed so that the thickness of the portion where the head insertion hole and the pinch roller insertion hole are formed is larger than the thickness of the other portion.

This is particularly noticeable in the case of the cassette half of the conventionally known CONT4 tape cassette.

Then, the cassette half is mounted so that the thicker portion thereof faces the base 13m of the cassette holder 13. Therefore, if the lock slider 2 is disposed near the base 13a of the cassette holder 13 in the main chassis 11, the overall thickness of the micro cassette tape recorder becomes thicker, which results in the inconvenience of miniaturization.

As shown in FIG. 1, with the cassette holder 13 closed, the parts of the main chassis 11 that do not correspond to the thicker part of the cassette half, the tabs, and the reel stand 18. A lock slider 2 is located between the operating portion 12 and the imaginary line connecting the axes of the reel stand 18 and 19.

ASO lever 22. By providing the opening/closing detection lever 23, the high-speed slider 24, etc., it is possible to promote the thinning of the entire microcassette tape recorder, which in turn can contribute to miniaturization.

As described above, the lock slider 21 that locks the tape running operating member at the operating position is mounted on the surface of the main chassis 11 that faces one of the flat surfaces of the tape cassette, and on the thicker part of the tape cassette. A feature of the present invention is that it is disposed in a portion that does not face the opposite side, thereby promoting miniaturization.

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

〔Effect of the invention〕

Therefore, as described in detail above, according to the present invention, the arrangement position of the locking member that locks the tape running operating member that brings the tape into a predetermined running state at the operating position is selected, so that it is organically compact. Therefore, it is possible to provide an extremely good tape recorder device that facilitates the development of a wide range of applications.
