Abstract

PURPOSE:To prevent assuredly the deflection of a tape due to the revolution inertia of a flywheel, etc. when a tape is changed to a pause mode from a constant speed drive mode with a simple constitution, by providing a control mechanism which sets rotor in a non-transmission state of revolving power in response to the operation of a tape drive stop control member. CONSTITUTION:A high-speed slider 24 is slided downward with each operation of a quick traversing control plate, a rewind control plate and a temporary stop control plate respectively. Thus a constant speed gear 19f is separated from a constant speed gear 39 via a gear control slider 43 and a gear control lever 44 to prevent the transmission of the revolving power due to the inertia of a flywheel to the gear 19f. Therefore the drive of a micro-cassette tape is stopped immediately at a time moment when a stop control plate 27 is operated. This prevent the deflection of the tape.

) Press in the direction of medium pressure. Therefore, the gear control lever 44 is rotated counterclockwise in FIG. 9(b), and the other end 44
c slides the constant speed gear 19f against the biasing force of the spring 19b to the lower force in FIG. 29- Incidentally, when the suppressing operation of the stop operation plate 27 is stopped, the stop operation plate 27 is returned to the upper blade in FIG. The speed gear 19f is biased by the spring J9h as shown in Fig. 9(b).
Of course, it is slid by the middle upper blade and meshed with the constant speed gear 39.

Further, the operation of separating the constant speed gear 1.9f 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. It is something.

Further, suppose that the micro cassette tape recorder is in the playback state and the pause operation plate 30 is suppressed as shown in FIG. 10 (0).
0 is locked at the operating position shown in FIG. 1O (,) by a button-button mechanism (not shown), as described above. At this time, the protruding piece 30m of the temporary stop operation plate 30 presses the retaining portion 24c of the high-speed slider 24 at 3 in Fig. 10 (,).
0- Since it is pressed downward, the high speed slider 24 is slid downward in FIG. Therefore, the retaining portion 24c of the high-speed slider 24 presses the locking piece 43b of the gear control slider 43 downward in FIG. 1O, and the gear control slider 43 is eventually slid downward in FIG. 10 (,). It is. Therefore, as mentioned earlier, Fig. 10 (b
), the gear control lever 44 is rotated in the medium clockwise direction in FIG. 10(b), and the constant speed gear 191 is slid downward in FIG. 10(b) and separated from the constant speed gear 39. There is something out there. Therefore, the rotational force of the constant speed gear 39 is no longer transmitted to the reel shaft 19e via the constant speed gear 19f, so that the running of the micro cassette tape in the reproducing state can be temporarily stopped.

Then, when the temporary stop operation plate 30 is operated to suppress it again at the operation position shown in FIG. The gear control slider 43 is also returned in the same direction. Therefore, the constant speed gear 19f meshes with the rotating constant speed gear 39, and the micro cassette tape can again run in the playing state.

Now, as is clear from the above description.

The high-speed slider 24 operates at the tenth position when the fast-forward operation plate 29, the rewind operation plate 28, and the pause operation plate 30 are operated.
The gear control slider 4 is slid downward in the figure (,).
3 and the gear control lever 44 to separate the constant speed gear 191 from the constant speed gear 39.

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

Here, as explained in FIGS. 9(a) and 9(b), it will be explained that the constant speed gear 19f can be detached from the constant speed gear 39 in conjunction with the operation of the stop operation plate 27. do. That is, for example, when the micro cassette tape recorder is put into the playback state and the stop operation plate 27 is operated, the playback operation plate 2 is activated as described above.
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 micro cassette tape is stopped. However, even if the power supply 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 inherent nature.

The constant speed gear 39 is connected to the flywheel 17.
The rotational force of the flywheel 17 is transmitted and rotates, so if the constant speed gear 39 and the constant speed gear 19f are in mesh with each other when the stop operation plate 27 is operated, the flywheel 17
The rotational force due to the nature of the rotational force will be transmitted to the constant speed gear 19f. For this reason, the reel shaft 19c is rotated extra by an amount corresponding to the inherent rotation of the flywheel 17, and the running of the micro cassette tape cannot be stopped immediately when the stop operation plate 22 is operated, so that the so-called tape run is not stopped immediately. 33-- There is a problem that a flow occurs.

However, as shown in Figures 9(a) and (b),
By causing the constant speed gear 19f to separate from the constant speed gear 39 in conjunction with the operation of the stop operation plate 27, the inherent rotational force of the flywheel 17 is transferred to the constant speed gear J9.
It is possible to prevent the information from being transmitted to f. Therefore, the running of the micro cassette tape is stopped immediately when the stop operation plate 27 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 can happen when you operate .

As described above, when the stop operation plate 27 is operated while the tape is traveling at a constant speed, the constant speed gear 19f is moved to the constant speed gear 3.
The feature of this invention is that the tape is separated from the tape 9 to prevent the tape from running.

34-Next, the micro cassette tape recorder has an automatic stop mechanism (hereinafter referred to as an ASO mechanism) that automatically stops the micro cassette tape when it reaches the end in each state of playback, recording, fast forwarding, and rewinding. ), and the ASO mechanism will be explained 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 the substantially central portion thereof. It is rotatably supported. And this AS
O lever 22i11. , the biasing lever 39c is the protrusion 22 that protrudes downward in FIG. 3 from one end thereof. 'By being loosely fitted into a long hole 39e formed at one end, it is interlocked with the biasing lever 39c.

Further, the other end of the ASO lever 22 is formed with a retaining portion 22c (see FIG. 11) that comes into contact with the circumferential side of the eccentric cam portion 37d 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 rotates clockwise in FIG. 11 and the high speed gear 38 and constant speed gear 39 rotate in the same direction, the biasing lever 39c is also biased clockwise in FIG. be done. Therefore, the above ASO lever 22 is also attached to the mounting shaft 2.
The ASO lever 22 is biased clockwise in FIG.
7° While the high-speed gear 38 and the constant-speed gear 39 are rotating, the mounting shaft 2 follows the circumferential surface of the eccentric cam portion J7d.
It performs a rocking motion centering around 2b.

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 that can be fitted with 1& is formed. Although this protrusion 22d moves away from or approaches the protrusion piece 21a of the lock slider 21 when the ASO lever 22 is swinging as described above,
The engaging portion is stroked so as not to be touched by the protruding piece 211L.

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

This driven portion 22e can be fitted to a curved driving portion 37e 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 oriented such that it is always located on the inner circumferential side of the drive section 37e in FIG. 11 when the drive section 37e is passed. There is.

First, the automatic stop operation during playback will be explained. That is, when the micro cassette tape 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 gearbox 37 is moved clockwise in FIG. 11 by the rotational force of the motor 20. The high speed gear 38 and the constant speed gear 39 are rotated in the same direction. and.

The reel shaft 19e is rotated via the constant speed gear 19f meshed with the constant speed gear 39, and the ASO lever 22 performs a swinging motion.

When the microcassette tape reaches the end in such a reproduction state, the rotation of the reel shaft 19c and the constant speed gear 191 is forcibly stopped.

Therefore, the constant speed gear 39 meshed with the constant speed gear 19f
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 37d 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 slip occurs between the high speed gear 38 and the constant speed gear 39 via the friction member 40 (see FIG. 3).

Therefore, the ASO lever 22 has a retaining portion 22c.
is defined at the position pressed by the maximum diameter portion of the eccentric cam portion J7d of the drive gear 37, and thereafter is no longer followed by the eccentric cam portion 37d. When the ASO lever 22 is set at such a position, the drive gear 3
7 is rotated clockwise in FIG. 11, the driving portion 37e is engaged with the driven portion 22e.

In this case, the 11th
It is engaged on the outer peripheral side in the figure. For this reason, the ASO lever 22
As the driven portion 22e follows the outer periphery of the driving portion 37e of the driving gear 37, the driven portion 22e moves further to the first position than the specified position previously pressed by the maximum diameter portion of the eccentric cam portion J7d.
It is rotated counterclockwise in Figure 1.

At this time, the protrusion 22rl of the ASO lever 22 presses the protrusion 21a of the lock slider 21, causing the lock slider 21 to slide in the direction of arrow (movement) in FIG. The regeneration operation plate 26 is unlocked, the regeneration operation plate 26 is returned to the non-operation position, and an automatic stop is performed at this point.

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, when the lock slider 21 is slid in the direction of the arrow (G) in FIG. .

Next, before explaining automatic stopping operations during fast forwarding and rewinding, the limiter lever 37c will be explained. That is, this limiter lever 37a is
As shown in FIG. 11, it is formed into a substantially curved shape and is rotatably supported by a shaft 371 implanted in the drive gear 37 at its substantially central portion. This limiter lever 37
A pair of protrusions 38h and 38b are formed at one end of the high-speed gear 38 at opposing positions across the shaft 37a.
and a hook portion 3 that is selectively engaged with 38c and 38rl.
7g is formed. In addition, the limiter lever 37
cB, the spring 37b is engaged between the through hole 37b formed at the other end and the through hole 971 formed in the drive gear 37, so that the hook portion 37g is connected to the protrusion 3B. i p '38 b or 38c, 3
8tl is biased in the direction of engagement.

Now, as shown in Fig. 11, the limiter lever 3
The hook portion 37g of 7c is the protrusion 38*, 3 of the high speed gear 38.
Assume that the driving gear 37 is rotated clockwise in FIG. 11 by the rotation of the motor 2o while being engaged with the motor 8b.

Then, the rotational force of the drive gear 370 is applied to the limiter lever 37.
c to the high-speed gear 38, and this high-speed gear 38
The rotational force 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 together, the constant speed gear 39 stops rotating, but the high speed gear 38 stops rotating. (This state is the state in which the tape reaches the end in the playback state described earlier). When a load larger than the predetermined load is applied to the high-speed gear 38, the rotation thereof is stopped. At this time, the drive gear 37 is rotated clockwise in FIG. 11 by the rotational force of the motor 20, so the hook portion 37g of the limiter lever 37c is forcibly removed from the protrusions 38a+38b. Then, the hook portion 37g1ff, the next protrusion J
8 c e 38 d is engaged, but it is forcibly disengaged again, and this operation is repeated thereafter, resulting in a state in which the rotation of the high speed gear 38 is stopped and the rotation of the drive gear 37 is continued. .

This state corresponds to the state in which the microcassette tape reaches the end in the fast forward and rewind states described below. That is, the drive gear 37 and the high speed gear 38 are interlocked by the limiter lever 37a, and the high speed gear 38 and the constant speed gear 39 are interlocked by the friction member 40, thereby creating a difference in the strength of the interlocking relationship. 42
- The reason for this will be explained later.

When the micro cassette tape recorder is put into the fast forward or rewind state, the fast forward operation plate 29 and the rewind operation plate 28 are locked to the lock slider 21 at the operation position, and the rotational force of the motor 20 The drive gear 37 is rotated clockwise in FIG. 11, and the high speed gear 38 and constant speed gear 39 are accordingly rotated in the same direction. For this reason, the reel shafts 19c and 18c are
are rotated respectively, and ASO Ray-q-2st
It is considered to be something that is performing a rocking motion.

When the microcassette tape reaches the end in such a fast forwarding and rewinding state, the rotation of the reel shafts 19c, 18c 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 and the driving gear 32 is kept rotating.

Further, at this time, as the rotation of the high speed gear 38 stops, the rotation of the constant speed gear 390 is also stopped, and as described above, no biasing force is applied to the biasing lever 39c. For this reason, AS
The driven portion 22e of the O lever 22 is engaged with the driving portion 37e of the driving gear 37, and as described above, the lock slider 2
1 is slid in the direction of arrow (g) in FIG. Therefore, the fast forward operation plate 29 and the rewind operation plate 28, which were locked to the lock slider 21, are unlocked, and automatic stopping is performed.

Therefore, according to the above-described more advanced ASO mechanism, the high-speed gear 38. Since the constant speed wheel 39 and the biasing lever 39c, which transmit rotational force to the reel shaft 19c during recording and playback, are arranged coaxially, the occupied space is small and the micro cassette tape recorder can be downsized. In addition, since it is easy to unitize, it is advantageous in terms of assembly workability. Further, since both the high speed gear 38 and the constant speed gear 39 are rotated in the same direction, recording and playback are possible.

Since there is no need to consider that the rotation direction of the reel shafts 19c and 18c changes during fast forwarding and rewinding, the AS
The structure of the O mechanism can be simplified, and reliable operation can be achieved. Further, the high-speed gear 38 is connected to the reel shafts 19c and 18e, which are the winding side of the micro cassette tape during fast forwarding and rewinding, so as to be able to transmit rotational force, and the reel shaft 18c, which is the supplying side of the micro cassette tape during fast forwarding and rewinding. .

Since J9cld is unloaded, the tape can be run smoothly without applying unnecessary pack tension to the microcassette tape during fast forwarding and rewinding.

Here, as mentioned earlier, the drive gear 37 and the high speed gear 3
8 in an interlocking relationship via the limiter lever 37a,
A description will be given of how the high-speed gear 38 and the constant-speed gear 39 are interlocked via the friction member 40 so that the strength of the interlocking relationship is different. That is, during fast forwarding and rewinding, the rotational force of the high speed gear 38 is transmitted to the reel shafts 19c, 18c, and during recording and playback, the rotational force of the constant speed gear 39 is transmitted to the reel shaft 19c. However, as is well known in ordinary tape recorders, it is necessary to rotate the reel shafts 19c and 18c at high speed during fast forwarding and rewinding.
The driving force for rotating the reel shafts 19e and 18e must be stronger than the driving force for rotating the reel shaft 19e during recording and playback. However, if the driving force that rotates the reel shaft 19e during recording and playback is the same as the driving force that rotates the reel shafts 19c and 18a during fast forwarding and rewinding, it will be necessary to use more force than necessary during recording and playback. Since the reel shaft 19e is rotationally driven, when the microcassette tape reaches the end, unnecessary tension is applied to the tape, which may damage the tape and is also undesirable in terms of power consumption.

46- Therefore, the drive gear 37 and the high speed gear 38 are interlocked via the limiter lever 37c, and the high speed gear 38 and the constant speed gear 39 are connected to each other via the friction member 4°. By establishing a weaker interlocking relationship than the interlocking relationship, it is possible to set the rotational driving force applied to the reel shafts 19C and 18c to appropriate values during recording and playback, and during fast forwarding and rewinding. be.

Further, as a means of interlocking the driving gear 37 and the high-speed gear 38, it is conceivable to interpose a friction member between the driving gear 37 and the high-speed gear 38, but if this is done, the third In addition to the springs 38b and 39d shown in the figure, a separate spring is required to press the high-speed gear 38 against the drive gear 37, and this spring generates an urging force approximately 10 times or more than the spring 38b described above. Otherwise, it would be impossible to differentiate the strengths of the two interlocking relationships as described above, and the structure would end up being complicated and not practical.

For this reason, as shown in figure 1, if limiter) #
-By using the J7c and the spring 37b, etc., to form an interlocking relationship between the drive gear 37 and the high speed gear 38, it is possible to realize an interlocking relationship with a predetermined strength with a simple configuration. , it is extremely practical.

Next, the micro cassette chip 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 teso is running in the fast forward 9 and rewind states, the ASO mechanism will automatically stop the micro cassette teso. This prevents the capstan 16 from being wrapped around the capstan 16 or being damaged. That is, as shown in FIG. 12, the ASO lever 22 has a protruding piece 22f formed near its driven portion 22e. 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 be engaged with the tip 13e of the extending portion 13a extending from one of the clamping portions 13c of the cassette holder 13. .

The opening/closing detection lever 23 has a coiled spring 23e engaged between an engaging part 23c formed between one end thereof and the shaft 23a and a protrusion 23d formed on the main chassis 11. By being attached, 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, the opening/closing detection lever 231rJ, FIG.
As shown in a), when the cassette holder 13 is in the closed state, its tip 13e presses the inclined portion 23b of the opening/closing detection lever 23 in the direction shown in FIG. It is rotated clockwise in FIG. 12 against the force. Therefore, one end of the opening/closing detection lever 23 is separated from the protruding piece 221 of the ASO lever 22, and the ASO lever 22
is designed to be able to freely perform the above-mentioned rocking motion.

Further, as shown in FIG. 13(b), when the cassette holder 13 is in the open state, the opening/closing detection lever 23 has its tip 13e connected to the inclined part 2 of the opening/closing detection lever 23.
3b, it is rotated counterclockwise in FIG. 12 by the biasing force of the spring 23a. Therefore, one end of the opening/closing detection lever 23 is connected to the ASO lever 2.
The ASO lever 22 is engaged with the second protruding piece 221, and the ASO lever 22 is engaged with the first
It is rotated clockwise in Figure 2. At this time, the ASO lever 22 is configured such that its retaining portion 22c is defined at approximately the same position as the position pressed by the maximum diameter portion of the eccentric cam portion J7d of the drive gear 37.

Here, assume that the cassette holder 13 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 described above, the drive gear 37 is rotated clockwise in FIG. 12, and while the micro cassette tube is running, the ASO lever 22 performs a rocking motion and is brought into a stable regeneration state. .

Assume that the cassette holder 13 is opened in this reproduction state. Then, as described above, the opening/closing detection lever 23 is rotated clockwise in FIG. It is rotated counterclockwise in the figure. Therefore, as shown in FIG.
When the is rotated clockwise in the figure, the drive portion 37e is
It is engaged with the driven portion 22e of the SO lever 22. Then, similarly to the automatic stop operation described above, the protrusion 22d of the ASO lever 22 engages with the protrusion piece 21111 of the lock slider 21, causing the lock slider 21 to slide in the direction indicated by the arrow in FIG. The operation plate 26 is returned to the non-operation position, the rotation of the motor 20 is stopped, and problems such as the micro cassette tube being wrapped around the cab stan 16 can be prevented.

In addition, the above-mentioned safety measures also apply when the cassette holder 13 is opened while the micro cassette chip 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 utilized, when the cassette holder 13 is in the open state, the member for stopping the micro cassette chip recorder is the open/close detection lever 23. Since only the spring 23e and spring 23e are required, the structure is extremely economical and organic, and can operate reliably.

Here, the above-mentioned recording, playback 2 rewind and fast forward operation board 25
, 26, 28, and 29 in the operation position, and engages with the stop operation plate 27 and the ASO-22 to lock each operation plate 2.
As shown in FIG. 1, the lock slider 21 for releasing the lock at 5,26,28°29 is provided on the front side of the main chassis 11, that is, on the side facing the microtape cassette. For this reason, the main chassis 11
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 surface side of Figure 1, and to ensure smooth and reliable operation. 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 above.

By the way, as is clear from FIG. 1, the lock slider 27, ASO lever 22. Open/close detection lever 23
The high-speed slider 24 and the like are arranged in the main chassis 11 in the vicinity of the reel stand 18.19 and between an imaginary line connecting the axis of the reel stand 18.19 and the operation unit 12;
5 disposed near the base 13a of the cassette holder 13.
3- It is made so that it does not occur. This is due to the shape of the cassette half of the microtape cassette.

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

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

Then, the cassette half is mounted so that the thicker part faces the base 13a of the cassette holder 13. For this reason, if the lock slider 21 and the like are arranged in the vicinity of the base 13a of the cassette holder 13 in the main chassis 11, the thickness of the entire microcassette tape recorder increases, which is inconvenient to miniaturization.

Therefore, when the cassette holder 13 is closed, as shown in FIG. , Q, Q - An imaginary line connecting the vicinity of the reel stand 1g and 19 and the axes of the reel stand 18 and 19 and the operation section I
2, the lock slider 21°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.

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 detailed above, according to the present invention, when the tape is changed from a constant speed running state to a stopped state, it is possible to reliably prevent the tape from flowing due to the rotation nature of the flywheel, etc. with a simple configuration. At the same time, it is possible to provide an extremely good tape recorder device which can effectively promote downsizing and weight reduction and is particularly suitable for micro cassette chip recorders.
