Description

[Detailed Description of the Invention] This invention relates to an improvement of an operator attachment mechanism for a tape recorder.

In recent years, there has been a demand for tape recorders that are small, lightweight, portable, and capable of long-term recording and playback, and in response to this demand, for example, microcassette tape recorders have been developed.
The next requirement for such a microcassette tape recorder is to make the shapes and combinations of the various parts organic, to reduce the number of parts, and to ensure smooth and reliable operation. It is to do so. In particular, for example, if you operate the rewind control in the recording mode, the record control will be unlocked at the operating position and will enter the review mode, allowing you to rewind. A more user-friendly and high-performance model equipped with various mechanisms such as a mechanism that automatically starts playing the previously recorded content (when you stop operating the controls) and an automatic stop mechanism (AOS). , is strongly requested.

This idea was made based on the above-mentioned circumstances, and it has a simple structure to attach the operator and the operation slider that moves each movable member of the tape recorder mechanism to a predetermined position in conjunction with the operation of the operator. Another object of the present invention is to provide an extremely good tape recorder operator attachment mechanism that can be easily and accurately installed.

Hereinafter, one embodiment of this invention will be described in detail with reference to the drawings. FIG. 1 shows the appearance of a microcassette tape recorder to which this invention is applied. That is, this microcassette tape recorder is sized so that the user can easily hold it in his/her left hand, and the approximately box-shaped cabinet 11 accommodates a microtape cassette (not shown) and stores the tape therein. A tape recorder mechanism section 12, a speaker section 13, and an operation section 1 for making the machine run and stop in a predetermined state.
4th class is arranged. Among these, the operation section 14 includes recording, playback, fast forward, rewind, stop and eject operators 15 to 19, as well as tape running speed ±10 from normal in tape recording or playback state.
[%] A changeover switch 20 for speeding up or slowing down, a changeover switch 21 for changing the tape running speed during recording and playback to 1.2 [cm/sec] or 2.4 [cm/sec], respectively, are provided. It is being The recording, playback, fast forward, rewind and stop/inject controls 15 to 19, changeover switches 20, 21, etc. can be easily operated by the user using only the thumb of the left hand, and can be operated with one touch using only one hand. I am learning how to do it.

In the figure, 22 is a built-in microphone, 23 is an external input jack, 24 is an earphone jack,
25 is a volume adjustment dial, 26 is a pause (for temporarily stopping tape running) operator, 27 is a carrying band, 28 is a tape counter, and 29 is its reset button.

FIG. 2 shows the tape recorder mechanism section 12 taken out, and its outline will first be explained. That is, in the figure, 30 is a main chassis, and a pair of reel stands 31 and 32 are rotatably supported approximately at the center thereof. This reel stand 3
1 and 32, a capstan 33 is rotatably supported, and on both sides of this capstan 33 are guide pins 34 and 35 for mounting a microtape cassette (not shown).
are planted in each. Also, the capstan 3 is placed on the substantially perpendicular bisector of the reel stands 31 and 32
A leaf spring 36 for holding the microtape cassette in the attached state is provided on the side opposite to the side where the microtape cassette 3 is provided. Furthermore, the main chassis 3
A motor 37 is attached to one corner of 0.

Here, at one end of the main chassis 30, the recording, playback, fast forward, rewind, and stop/eject operators 15 to 19 are supported so as to be movable in the directions of arrows A and B in the figure, respectively. For example, when the playback operator 16 is pressed in the direction of arrow A, the pinch roller 38 installed opposite to the capstan 33 is pressed against the capstan 33, and the recording/playback head 39 installed in parallel with the pinch roller 38 is pressed. Moved in the direction of operation. At this time, the reel stand 32 rotates in the direction of arrow C in the figure,
The tape recorder mechanism section 12 is placed in a playback state. Further, as will be described later, the recording operator 15 can be operated simultaneously with the playback operator 16, and when both operators 15 and 16 are operated together, the pinch roller 38, the recording/playback head 39, and the reel stand 32 are brought into the above-mentioned playback state. In addition, in conjunction with the operation of the recording operation element 15, the erasing head 40, which is arranged in parallel with the recording/reproducing head 39, is moved in the operating direction, and the tape recorder mechanism section 12 is brought into the recording state. be.

Furthermore, when the fast-forward operator 17 is operated, the reel stand 32 rotates faster in the direction of arrow C than during playback.
When the rewind operator 18 is operated, the reel stand 31 rotates at high speed in the direction of arrow D, and the tape recorder mechanism section 1
2 is a fast forward state and a rewind state. The recording, playback, fast forward, and rewind controls 15 to 18 are locked in their operating positions, but the locking of these controls 15 to 18 in their respective operating positions is due to the stop and eject controls. It can be canceled by operating 19.
When the stop/eject operator 19 is operated once, when any one of the recording, playback, fast forward, and rewind operators 15 to 18 is being operated, the stop/eject operator 19 releases the lock of the operator 15 to 18.
When operated for the second time, an eject member 41 provided near the motor 37 is rotated in the direction of the arrow in the figure, so that the microtape cassette can be ejected. In this microcassette tape recorder, ejecting means opening a cassette lid (not shown) covering the upper part of the tape recorder mechanism section 12, and the user can directly attach and detach the microtape cassette by hand.

Here, in this tape recorder mechanism section 12, when the fast forward or rewind operators 17, 18 are operated while the playback operator 16 is operated, the fast forward or rewind operators 17, 18 are not locked at the operating position. , it is in the queue or review state only while the press operation is being performed. Furthermore, if the rewind operator 18 is operated in a recording state in which both the recording and playback operators 15 and 16 are operated, only the recording operator 15 is unlocked, and the rewind operator 18 is locked at the operating position. First, it is in the review state only while the pressing operation is being performed, and when the operation is stopped, the playback state is entered by the playback operator 16, which is kept locked in the operating position, and the previously recorded content can be immediately played back. This is what is called a quick review. Furthermore, this tape recorder mechanism section 12 is provided with an automatic stop mechanism that operates only in the recording or playback state.

Further, a blind plate 42 is attached to a portion of the tape recorder mechanism section 12 where the micro tape cassette is attached. Furthermore, numeral 43 in the figure represents an erroneous erasure prevention member.

Here, the recording, playback, fast forward, rewind and stop/eject operators 15 to 19 are as follows:
They are arranged as shown in FIG. First, the recording operation element 15 is inserted through a through hole 161 formed in a part of the reproduction operation element 16 formed in the shape of a substantially rectangular parallelepiped, and the left side of the reproduction operation element 16 in the figure is inserted with a finger or the like. By pressing the button, both the recording and playback controls 15 and 16 are operated. and play, fast forward and rewind controls 16;
1 to 18 are arranged along the surface of the main chassis 30 on the upper side of the main chassis 30, respectively, and the stop/eject operator 19 is arranged on the lower side of the main chassis 30 in the figure, sandwiching the playback operator 16 and the main chassis 30. are placed in opposite positions.

By arranging each of the operators 15 to 19 as described above, operability can be rationally improved, and the structure can also be rationally reduced in size. That is, the operators 15 to 18 for running the tape are arranged in a row, and the operator 1 for stopping the tape running is arranged in a row.
9 are provided in separate rows, so the user can easily and accurately determine which operators are used for running the tape and stopping the tape running, sufficiently preventing erroneous operations and improving operability. It is.
This means that, for example, when an undesirable phenomenon such as tape winding occurs while the tape is being played back, users may accidentally operate the fast forward, rewind, etc. controls 17 and 18 in an attempt to immediately stop the tape running. It is also related to tape protection, such as being able to sufficiently prevent.

In addition, the tape running operators 15 to 18 are arranged on the upper surface of the main chassis 30, and the tape running stop operator 19 is arranged on the lower surface, so that they are linked to the operation of each operator 15 to 19. Each operation slider, lock plate, etc., which will be described later, can be supported on either side of the main chassis 30 as required for the configuration, and this can contribute to rational downsizing of the tape recorder. .

Further, a lock member 50 is rotatably supported at the tip of the pin 306, and the lock member 50 is urged in the direction of the arrow in FIG. 5 by a torsion spring 51. When the locking portion 501 of the locking member 50 and the bent locking piece 492 formed in the long hole 491 of the recording operation slider 49 are engaged, the recording operation slider 49 is locked at the operating position. This is something that is increasingly being done.

Further, the other end of the recording operation slider 49 is brought into contact with a protrusion 521 of a transmission member 52 rotatably supported by the shaft 307 of the main chassis 30 .

At this time, the erroneous erasure prevention member 43 is rotatably supported at a position facing one end of the recording slider 55 of the main chassis 30. This erroneous erasure prevention member 43 is biased clockwise in FIG. 4 by a torsion spring 58. Then, with the microtape cassette installed,
If the accidental erasure prevention claw is broken, the locking portion 431 of the accidental erasure prevention member 43 rotates clockwise in the figure.
This position is opposite to one end of the recording slider 55. Therefore, the recording slider 55 is not slid upward in the figure, and the recording operator 15 is not operated, thereby preventing erroneous erasure. In addition, if the accidental erasure prevention claw of the microtape cassette is not broken, the accidental erasure prevention claw comes into contact with the engaging portion 432 of the accidental erasure prevention member 43, and the accidental erasure prevention member 43 is rotated counterclockwise in the figure. let

Further, the rotation of the motor 37 is transmitted to the flywheel 89 and the pulley 811 of the gear pulley 81 via a belt 94.

Next, the detailed configuration and operation of each part of the tape recorder mechanism section 12 will be explained. That is, as shown in FIG. 7, a protrusion 162 is integrally formed on the reproduction operator 16 at a position facing the leaf spring-shaped contact piece 721 of the switch 72. As shown in FIG. The switch 72 is connected to the contact piece 721.
It has a plate spring-shaped contact piece 722 that is substantially parallel to the above, and the mutually opposing tips of both contact pieces 721 and 722 have a
Engagement electrodes 723 and 724 are formed, respectively. Further, the contact piece 721 is provided with a spacer 725 for ensuring a distance from the contact piece 722, and a spacer 725 that comes into contact with the protrusion 162 of the playback operator 16 and protects the engaging electrodes 723 and 724 from being strongly pressed against each other. A protective member 726 is attached.

Furthermore, at this time, the pinch lever 61 is biased counterclockwise in the figure around the pin 60 by the torsion spring 65, but its rotation is controlled by a fold formed at one end of the pinch lever 61. The music engagement piece 611 is connected to the playback operation slider 5 shown in FIG.
9, the pinch roller 38 is pressed against the step 599 formed on one side of the capstan 3.
3 so as not to come into contact with it. Further, one end of the connecting lever 85 protruding from the upper surface of the main chassis 30 (indicated by a solid line in the figure) is engaged with the bent engagement piece 611 of the pinch lever 61 and the one end 641 of the transmission lever 64. .

Here, as shown in FIG.
Suppose that the button is pressed in the direction of the arrow in the figure. Then,
The playback operation slider 59 is also slid in the same direction,
The head lever 62 and the transmission lever 64 supported by the pin 595 of the regeneration operation slider 59 are also moved upward in the figure. At this time, the head lever 62 is urged counterclockwise in the figure by the spring 63 around the pin 595, and its rotation is controlled by the head lever 62 being moved by the regeneration operation slider 59.
The head lever 62 is moved in parallel to the position shown in FIG. 8 while remaining in the state shown in FIG. . Therefore, the recording/reproducing head 39 is moved upward in the figure and comes into contact with the tape surface of a microtape cassette (not shown).

Also, since the playback operation slider 59 is moved upward in the figure, the stepped portion 599 is aligned with the pinch lever 61.
The pinch lever 61 is rotated counterclockwise in the figure by the biasing force of the torsion spring 65, and the pinch roller 38 is pressed against the capstan 33 via the tape. It is something. When the playback operation slider 59 is in its operating state, the lock portion 598 is locked to the bent portion 764 of the lock plate 76, so that
Locked in operating position.

At this time, the protrusion 162 of the playback operator 16 presses the protection member 726 of the switch 72, and the contact piece 7
The engaging electrodes 723 and 724 of 21 and 722 are brought into contact with each other. Therefore, the motor 37 rotates clockwise in FIG. 4, causing the gear pulley 81 and flywheel 89 to rotate in the same direction. here,
Since the gear 812 of the gear pulley 81 is normally meshed with the gear 45, the reel stand 32 rotates clockwise via the gears 45 and 44, and the tape is played back.

Note that when the switch 72 is turned on, a stabilized DC voltage is supplied to the motor 37 via a governor circuit, which will be described later.
At this time, the motor 37 rotates at a constant speed to run the tape.

Therefore, according to the above configuration, since the head lever 62 is directly attached to the regeneration operation slider 59 via the pin 595, it is possible to sufficiently contribute to reducing the number of parts and simplifying the configuration, and also to ensure reliable operation. It is possible to perform certain actions.
In this regard, in conventional tape recorders, the playback operation slider and the head chassis to which the recording/playback head is attached are interlocked via a spring or another member, or by mechanical engagement with each other. . For this reason, the number of parts tends to increase, which leads to a complicated structure and an increase in size, and when the parts are made small, there is a problem that the engaged state is uncertain and malfunctions are likely to occur.

However, since the head lever 62 is directly attached to the regeneration operation slider 59 rather than simply engaged, the interlocking relationship between the regeneration operation slider 59 and the head lever 62 can be achieved naturally and reliably, and the number of parts can be reduced. It is possible to promote the simplification of the configuration, and in turn, it can sufficiently contribute to downsizing of the tape recorder.
Further, in particular, in conventional tape recorders, the playback operation slider and the head chassis are arranged in a plane so that they slide in the same direction, resulting in an inconvenience that the occupied area becomes large. However, in the above configuration, the playback operation slider 59 and the head lever 62 are made substantially perpendicular to each other and are attached using the pin 595, so the attachment means is extremely simple and no space is required for attachment, and in this respect, the playback operation slider 59 and the head lever 62 are also compact. This will be advantageous for

In addition, a protrusion 162 formed on the playback operator 16
Since the drive switch 72 of the motor 37 is directly turned on and off using the switch, there is no need for a separate switch slider or the like as in the past, and the configuration is extremely simple and reliable switch switching is performed. It is something that can be done. Furthermore, the playback operator 16 (including the other operators 15, 17 to 19) protrudes from the tape recorder cabinet 11 to the outside. Disposing the switch 72 within the movement path of the playback operator 16 essentially means that the switch 72 is disposed close to the outside of the cabinet 11. This means that the switch 72
This means that it cannot be placed within 2. That is,
In tape recorders that are designed to be miniaturized, various parts are densely arranged on the main chassis 30.
Moreover, it is impossible to provide the switch 72 on the main chassis 30, and providing a space for installing the switch 72 is contrary to miniaturization. Therefore, by directly turning the switch 72 on and off with the playback operator 16, the switch 72 is installed outside the tape recorder mechanism 12, and reliable switch switching is possible. It is possible to organically promote the

Here, in the above-described playback state, as shown in FIG. 9, the playback operation slider 59 moves upward in the figure, so that the bent locking piece 593 separates from the protruding piece 502 of the locking member 50. . For this reason,
The lock member 50 is a torsion spring 51
It rotates counterclockwise in FIG. 9 due to the urging force (see FIG. 5). At this time, the rotation of the locking member 50 is such that the locking portion 501 is connected to the recording operation slider 49.
It is bent to a position facing the locking piece 492 (see FIG. 5). Therefore, even if you try to operate the recording operation element 15 in the playback state, the bent locking piece 492 of the recording operation slider 49 comes into contact with the locking part 501 of the locking member 50, making it impossible to operate it. This is designed to prevent follow-up recording.

Further, suppose that the fast-forward operator 17 is pressed in the above-described playback state, as shown in FIG. Then, the bent locking piece 663 (see FIG. 5) formed on one side of the fast-forward operation slider 66
It comes into contact with one end of the connecting lever 85 and rotates the connecting lever 85 counterclockwise in FIG. Therefore, the bending engagement piece 611 of the pinch lever 61 and the one part 641 of the transmission lever 64 are connected to the connecting lever 8.
5, the pinch lever 61 and the transmission lever 64 are respectively rotated slightly clockwise in the figure. As a result, the pinch roller 38 separates from the capstan 33 and the transmission lever 64
One side 641 of the head lever 62 presses the bent engagement piece 623 of the head lever 62 and rotates the head lever 62 slightly clockwise in the figure against the biasing force of the spring 63, so that the recording/playback head 39 It is retracted until it touches the surface. At this time, the tape is run at high speed in the fast-forward direction, and the tape recorder mechanism 12 is placed in a fast-forward playback state, a so-called queue state. Here, as shown in FIG.
98 is locked to the bent portion 764 of the lock plate 76, the lock portion 662 of the fast-forward operation slider 66 is configured not to be bent by the bent portion 765 of the lock plate 76. Therefore, the queue state can occur only while the fast-forwarding operator 17 is pressed.

On the other hand, assume that the rewind operator 18 is operated while the tape is being played back. Then, the rewind operation slider 77
Stepped portion 776 formed on one side of (see Figure 6)
is in contact with the upright locking piece 852 of the connecting lever 85, and the connecting lever 85 is rotated counterclockwise in FIG. Thereafter, the pinch roller 38 and the recording/reproducing head 39 are moved to the same position as in the queue state, and the tape is run at high speed in the rewinding direction, and the tape recorder mechanism 12 is brought into a rewinding and reproducing state, a so-called review state. It is something that At this time, the rewind operation slider 77 is also configured so as not to be locked at the operating position, and can enter the review state only while the rewind operation element 18 is being pressed.

Also, when both the recording and playback operators 15 and 16 are operated, the pinch roller 38 and the recording/playback head 3
No. 9 etc. are all placed in the position described above in the reproduction state. At this time, the recording operation slider 49 has its bent locking piece 492 connected to the locking portion 50 of the locking member 50.
1 and is locked in the operating position, and the 4th
As described in the figure, the erasing head 40 moves forward so as to come into contact with the tape surface, and recording is performed here.

In such a recording state, the rewind operator 18
Suppose you operate Then, as described above, the connection lever 85 is rotated counterclockwise in FIG. 10, and the transmission lever 64 is rotated clockwise in the figure. At this time, as shown in FIG.
The other part 642 of 4 is the upright piece 50 of the lock member 50.
3, and rotates the locking member 50 clockwise in FIG. Therefore, the locking portion 501 of the locking member 50 is disengaged from the bent locking piece 492 of the recording operation slider 49, and only the recording operation slider 49 is unlocked at its operating position. Thereafter, if the rewind operator 18 is continued to be pressed, the rewind operator 18 enters the review state as described above.
When the operation is stopped, the playback operation element 11 remains locked at the operating position, so the playback state continues. That is, a so-called quick review is performed in which the previously recorded content can be automatically rewound as a review state simply by operating the rewind operator 18, and then played back by stopping the operation of the rewind operator 18. It is something that can be done.

Next, the operation of the tape recorder mechanism section 12 when the rewind operator 18 is operated will be explained. That is, as shown in FIG. 11, when the rewind operator 18 is pushed to the right in the figure, the rewind operation slider 77 is also moved in the same direction. Therefore, the inclined portion 774 of the rewind operation slider 77 allows the pin 79 of the rewind slider 79 to
5 is pushed away, and the rewind slider 79 is slid to the left in the figure. As a result, the gear 812 of the gear pulley 81 is separated from the gear 45, and the gear 45 is moved away from the gear 45.
meshes with 7. Then, the gear 47 and the reel stand 3
1 is rotated in the direction of arrow H in the figure, and the tape is rewound here.

At this time, a switch to be described later is turned on in conjunction with the movement of the rewind operation slider 77. When this switch is on, it applies a DC voltage to the motor 37 without going through the governor circuit, and the motor 37 rotates at a higher speed than when it is in the recording and playback mode to rewind the tape. .

Here, in the rewinding slider 79, as shown in FIG.
By inserting the inside, it can be slid freely in the left and right directions in the figure. And this long hole 79
1,792 has a substantially rectangular shape as shown in the figure, and its left end in the figure is narrower in the lateral direction, and its right end in the figure is wider in the lateral direction. Here, in the normal state, as shown in FIG. 12a, the rewinding slider 79
are urged rightward in the figure by a spring 80, and the pins 753, 755 are inserted into the respective elongated holes 791, 7.
It is located at the left end of 92.

In this state, when the rewind operation slider 77 is operated upward in the figure, the rewind slider 79 is slid to the right in the figure, as shown in FIG. 12b, and the gear 812 and the gear 47 are It's something that fits together. At this time, each pin 753, 755 is positioned at the right end (wide side) of the elongated hole 791, 792. At this time, the pin 795 of the rewind slider 79 is pressed by the inclined portion 774 of the rewind operation slider 77, so the rewind slider 79 as a whole is rotated slightly counterclockwise in the figure. It turns out. This means that
This means that the gear 812 can be meshed with the gear 47 without any modification, as seen from the direction of rotation.

Therefore, elongated holes 791 and 792 as shown in FIG. 12 are formed in the unwinding slider 79, and the elongated holes 79
Since pins 753 and 755 are inserted into pins 91 and 792, respectively, and the rewinding slider 79 is biased diagonally by a spring 80 between the pin 755 and the pin 795, when the pin 795 is pressed by the inclined portion 774, The gear 812 connects the rewinding slider 79 to the gear 4.
7 can be engaged from the direction of biting, so that the rewinding operation can be carried out easily and reliably.

Furthermore, when the fast-forwarding operator 17 is operated, the gear 812 of the gear pulley 81 is normally engaged with the gear 44 of the reel stand 32, so the fast-forwarding state is entered as is. Note that even in this fast-forward state, the switch is turned on in conjunction with the fast-forward operation slider 66. Therefore, a DC voltage is applied to the motor 37 without going through the governor circuit, and the tape is fast-forwarded.

Here, the recording slider 55 (see FIG. 5)
The guide portion 309 that is slidably supported on the main chassis 30 will be explained. That is, as shown in FIG. 13, the guide portion 309 is formed by cutting and raising a predetermined portion of the main chassis 30. As shown in FIG. Specifically, as shown in FIGS. 14a and 14b, a predetermined portion of the main chassis 30 is formed into a substantially semicircular shape in which the width l ₁ of the base portion 951 is smaller than the width l ₂ of the tip portion, that is, the base portion 951 is cut and raised in the shape of a slightly constricted tongue in the width direction, and its tip 952 is bent approximately parallel to the surface of the main chassis 30, resulting in a so-called cut and bent shape.

The guide portions 309, 309 formed as described above are inserted into the long holes 551, 551 of the recording slider 55 as previously described in FIG. It is something to do.

Therefore, as described above, the guide portion 309
By forming the recording slider 55, the recording slider 55 can be guided without separately installing a guide pin or the like in the main chassis 30, and the number of parts can be reduced and the configuration can be extremely simple. Further, the guide portion 309 can be cut and bent at the same time by die cutting or the like, making manufacturing extremely easy.

Here, the reason why the width l ₁ of the base portion 951 of the guide portion 309 is made smaller than the width l ₂ of the tip portion 952 will be explained. In other words, when a predetermined portion of the main chassis 30 is cut and raised into a tongue shape, and the tip 952 of the cut and raised portion is bent so as to be approximately parallel to the surface of the main chassis 30, the bending pressure applied to the base 951 is Therefore, the base portion 951 is included in the width direction by the amount narrowed in the thickness direction. Therefore, taking into consideration the inclusion of the base 951 in the width direction, the width l ₁ of the base 951 when cut and raised is
is made smaller than the width l ₂ of the tip portion 952.

Next, the playback, fast forward and rewind controls 16
The attachment of the playback, fast forward and rewind operation sliders 59, 66 and 77 to the sliders 59, 66 and 77 will be explained.
That is, as shown in FIG. 15, at the rear end of each of the playback, fast forward and rewind operators 16 to 18,
Play, fast forward and rewind operation sliders 59, 6
6 and 77, which are bent into a substantially L-shape, are brought into contact and fixed. Here, the rewind operator 18 and the rewind operation slider 77
Since the attachment of the other playback and fast-forward operation sliders 16 and 17 and the playback and fast-forward operation sliders 59 and 66 is the same, the explanation thereof will be omitted.

First, one end of the rewind operation slider 77 is bent into a substantially L shape to form a mounting portion 777. A notch 778 is formed on one side of the attachment portion 777 into which a pin 181 protruding from the rear end surface of the rewind operator 18 can be fitted. Also,
At a predetermined position of the mounting portion 777, there is a through hole (not shown) into which a screw 96 is inserted, which is screwed into a screw hole (not shown) formed on the rear end surface of the rewind operator 18.
is formed. Further, in the upper part of the rear end view of the rewinding operator 18, a canopy-shaped protrusion 182 is formed so as to protrude by approximately the thickness of the attachment part 777, as shown in FIG.

The mounting portion 77 of the rewind operation slider 77
7 in FIG. 16 is brought into contact with the protrusion 182 of the rewind operator 18, and in this state slide the attachment part 777 along the protrusion 182 to remove the notch 7.
A pin 181 is fitted into 78. Thereafter, by fixing the mounting portion 777 and the rewinding operation element 18 with the screws 96, the rewinding operation element 18 and the rewinding operation slider 77 are attached.

Therefore, according to the above-described attachment means for the rewind operation element 18 and the rewind operation slider 77,
The upper end of the mounting portion 777 in FIG. 16 is in contact with the protrusion 182, and the notch 778 is fitted into the pin 181, so that the connection between the rewind operator 18 and the mounting portion 777 in the vertical and horizontal directions is Positioning can be performed extremely easily. Also, screw 96
Only one is required, which simplifies the configuration.

Here, playback operation slider 59 and playback operator 1
The screws 96 that fasten the substantially L-shaped receiving member 97 are also fastened together. A concave receiving portion 971 is formed at one end of this receiving member 97, and the torsion spring 69 is attached to this receiving portion 971.
One end (see FIG. 5) is locked, and the playback operator 16 is biased in the return direction.

Then, as described above, a mounting part is formed at one end of each operation slider, a notch is formed on one side of the mounting part, and the tip of the mounting part is connected to the protrusion (locking part) of the operator.
The feature of this invention is that each operator and each operating slider are attached by fitting the pin (protrusion) of the operator into the notch.

Next, as shown in FIG. 17, a brake 98 is attached to the stop operation slider 78, which comes into contact with the flywheel 89 when the stop operation slider 78 is pressed. There is. Now, as shown in FIG. 18, while the regeneration operator 16 is being operated, the stop/eject operator 19 is not being operated, so the brake 9
8 is not in contact with the flywheel 89. Therefore, the flywheel 89 rotates stably and the tape is played back. At this time, playback operator 1
Since the playback operation slider 59 is moved in the direction of arrow I in the figure in conjunction with the operation in step 6, the engagement portion 594
The eject lever 87, whose one end abuts, is rotated in the direction of arrow J in the figure. Therefore, the stepped portion 871 formed at the other end of the eject lever 87
The ejecting member 41 is located at a position that does not face the engaging portion 411 protruding from the lower surface of the main chassis 30.

Assume that in such a reproducing state, the stop/eject operator 19 is pressed as shown in FIG. Then, in response to the operation of the stop/eject operator 19, the stop operation slider 78 also moves in the same direction, and the lock plate 76 moves in the direction of the arrow K in the figure as described above.
The playback operator 16 is unlocked by moving in the direction shown in FIG. At this time, the brake 98 is moved to the flywheel 89.
is pressed, the rotation of the flywheel 89 is stopped, and tape running is immediately stopped based on this.
Here, when the lock plate 76 moves in the direction of arrow K in the figure, a protrusion 763 (sixth
(see figure) presses one end of the drive lever 86, causing the drive lever 86 to rotate in the direction of arrow L in FIG. Therefore, the eject lever 87 is pushed up slightly in the direction of arrow M in the figure. Also, at this time, the regeneration operation slider 59 returns to its original position, so that the engaging portion 594 is connected to the ejection lever 87.
It separates from one end. For this reason, the eject lever 87 is moved slightly in the direction of arrow M in the figure, and due to the biasing force of the spring 88 (see FIG. 6),
It is rotated in the direction of arrow N in the figure. At this time, the stepped portion 871 of the eject lever 87 does not engage with the engaging portion 411 of the ejecting member 41, and
It only comes into contact with the side wall of.

At this point, stop pressing the stop/eject operator 19, return it to its original position, and then return to the 20th position.
The stop/eject operator 19 is operated as shown in the figure. Then, the lock plate 76 slides in the direction of the arrow K in the figure, and as mentioned earlier, the protrusion 763
presses one end of the drive lever 86, causing the drive lever 86 to rotate in the direction of arrow L in the figure. Therefore, the eject lever 87 moves in the direction of the arrow M in the figure, and its stepped portion 871 engages with the engaging part 411 of the eject member 41, rotating the eject member 41 in the direction of the arrow O in the figure. An ejection operation is performed here. That is, when the stop/eject operator 19 is operated while the playback operator 16 is being operated, the playback operator 16 is unlocked, and when operated a second time, the double eject operation is performed. It is something that

In addition, as shown in FIG. 21, the rewind operator 1
8, the rewind operation slider 77
The stepped portion 776 contacts the connecting lever 85 and rotates the connecting lever 85 in the direction of arrow P in the figure. Therefore, the connecting lever 85 presses one end of the eject lever 87, and the connecting lever 85 presses the arrow J in the figure.
direction, and the stepped portion 871 is placed in a position where it does not face the engaging portion 411 of the ejecting member 41. Then, the tape is put into a rewind running state.

In this condition, stop/eject operator 1
9, the lock plate 76 moves in the direction of arrow K as previously explained in FIG. 19, the rewind operator 18 is unlocked, and the brake 98 is
is pressed against the flywheel 89, the rotation of the flywheel 89 is stopped, and tape running is stopped. At this time, in accordance with the movement of the lock plate 76, the eject lever 87 moves in the directions of the arrows M and N, and the stepped portion 871 moves against the eject member 41.
is not engaged. Then, when the stop/eject operator 19 is stopped and operated again, the 20th
Ejection is performed as explained in the figure.

Furthermore, when the fast forward operator 17 is operated,
The bent locking piece 663 (see FIG. 5) of the fast-forward operation slider 66 presses the connecting lever 85, and rotates the connecting lever 85 in the direction of arrow P in FIG. 21.
Therefore, similarly to the above, the eject lever 87 is placed in the position shown in FIG. 21, and the tape is rapidly forwarded. And stop/eject operator 19
When you operate the brake 98, the flywheel 89
When pressed, tape running is stopped, and the eject lever 87 is at the position shown in FIG. 19 and is not ejected. Thereafter, when the stop/eject operator 19 is stopped and pressed again, the eject lever 87 moves the eject member 41 as shown in FIG. 20, and eject is performed.

Therefore, a brake 98 is directly attached to the stop operation slider 78 that is linked to the operation of the stop/eject operator 19, and the rotation of the flywheel 89 is stopped by the brake 98.
To immediately and reliably stop tape running with a simple configuration, no matter what running state the tape is in.

In addition, since double eject can be performed via the lock plate 76 that is linked to the stop/eject operator 19, there is no need to newly equip a double eject mechanism, etc., and the configuration is extremely simple. At the same time, reliable operation can be performed.

Next, the main chassis 30 of the blind plate 42
This section explains how to install it. First, as shown in FIG. 5 again, the blind plate 42 is formed with through holes 421, 422 through which the reel stands 31, 32 are inserted, and through which the guide pins 34, 35 of the main chassis 30 are inserted. Approximately semicircular through hole 4
23,424 are formed. Further, screw holes are formed at the tips of the shafts 305, 307, 308 of the main chassis 30, and the shafts 305, 308 are provided with threaded holes.
Through holes 425 to 427 are formed in the portions of the blind plate 42 corresponding to the holes 7 and 308.

Here, as shown in FIG. 22, a regeneration operation slider 59 and a transmission member 52 are supported on the shafts 305, 307 of the main chassis 30. Then, the blind plate 42 is placed over this by inserting the guide pin 35 into the through hole 424. This guide pin 35 is attached to the main chassis 30.
A flange portion 351 is formed apart from the attachment portion of the playback operation slider 59 by the thickness of the blind plate 42 . Then, the blind plate 42 is inserted into the through hole 42.
With the guide pin 35 inserted into the second
As shown in FIG. 3, the edge of the through hole 424 of the blind plate 42 is inserted between the playback operation slider 59 and the flange 351 of the guide pin 35. In this state, the blindfold plate 42 can be temporarily fixed. Then, the screws 99, 99 are inserted through the through holes 425, 426 of the blind plate 42, and the shafts 305, 307 are inserted.
The blind plate 42 is attached to the main chassis 30 by being screwed to the main chassis 30.

In addition, when placing the blind plate 42 on the transmission member 52 and the regeneration operation slider 59 as shown in FIG. 35 is inserted. Thereafter, the blind plate 42 is rotated so as to cover the transmission member 52 with the through hole 426, and placed on the main chassis 30. Then, when inserting the guide pin 35 into the through-hole 424 of the blinding plate 42 and rotating the portion in which the through-hole 426 is formed to cover the transmission member 52, the left end 428 of the blinding plate 42 in the figure This can be easily done by being guided by the leaf spring 36 (see FIG. 5) for holding down the microtape cassette.

Here, in FIG. 22 and FIG. 23, the through hole 424 of the blind plate 42 and the guide pin 35 have been explained, but the other through holes 423 and the guide pin 34 have the same structure, and in the end, The blind plate 42 is temporarily fixed at two points, the guide pins 34 and 35.

Therefore, according to the mounting means for the blind plate 42 as described above, the blind plate 42 can be temporarily fastened before the screws 99 are fastened. The operational state of the tape recorder mechanism section 12 can also be tested in this state. Further, when placing the blind plate 42 on the main chassis 30 via predetermined movable members (transmission member 52, regeneration operation slider 59, etc.), the plate spring 36 serves as a guide, so assembly can be easily performed. It is something.

Next, the automatic stop mechanism of this tape recorder mechanism section 12 will be explained. That is, assuming that the tape recorder mechanism section 12 is now in the playback state, the flywheel 89 rotates in the direction of the arrow Q in the figure, as shown in FIG. , the gear 44 is rotated in the direction of arrow R, and stable tape playback is performed. At this time, the lock release lever 84 is activated by the torsion spring 785 (sixth
) is urged in the direction of arrow D in the figure, and one end of the lock release lever 84 is pushed into the extending portion 4.
The ASO lever 46 that comes into contact with 62 is indicated by arrow E in the figure.
biased in the direction. The other end of the lock release lever 84 faces a step 768 of the lock plate 76. Further, a pin 891 is provided near the rotation axis (capstan 33) of the flywheel 89.
A protruding pin 891 is formed in the tape playback state so that it does not come into contact with the engaging portion 841 formed at the center of the lock release lever 84 and having a sharp tip.

When the tape reaches the end in such a tape playback running state, the rotation of the reel stand 32 is stopped as shown in FIG. It is rotating in the R direction. For this reason, the tape is pulled and the gear 4
7, the ASO lever 46 is rotated in the direction of arrow S in the figure. The lock release lever 84 is then pressed by the extension portion 462 of the ASO lever 46.
is rotated in the direction of arrow T in the figure. At this time, the engaging portion 841 of the lock release lever 84 is located in the rotation path of the pin 891 of the flywheel 89.
Therefore, the pin 891 of the flywheel 89
Hitting the engaging part 841 of the lock release lever 84,
The lock release lever 84 is further rotated in the direction of arrow T. At this time, the other end of the lock release lever 84 presses the stepped portion 768 of the lock plate 76, causing the lock plate 76 to slide to the left in the figure. Therefore, the lock at the operating position of the playback operation slider 59 is released, and automatic stopping is performed at this point.

Here, the lock release lever 84 is the 26th lock release lever 84.
As shown in the figure, a long hole 842 is formed approximately in the center, and the main chassis 3 is located inside this long hole 842.
A pin 100 implanted in 0 is inserted through and rotatably supported. That is, the 27th
As shown in Figure a, when the lock release lever 84 is rotated (in the direction of arrow T in Figure 25) due to the rotation of the ASO lever 46, the lock release lever 84 still slides the lock plate 76. The stroke is not rotated enough. At this time, pin 10
0 is located at the left end of the elongated hole 842 in the figure. Then, the pin 891 of the flywheel 89 is struck by the tip of the engaging portion 841 of the lock release lever 84. Then, as shown in FIG. 27b, the pin 891 bites into the inclined portion of the engaging portion 841, and the lock release lever 84 is pulled until the pin 100 is located at the right end of the elongated hole 842 in the figure. and rotate clockwise in the figure. Therefore, the lock plate 76 is slid for the first time at this point, and automatic stopping is performed.

Therefore, a long hole 84 is formed in the lock release lever 84.
2, the pin 100 is located at the left end of the elongated hole 842 in FIG. 27 during tape playback and is biased in the direction of arrow D in the figure as shown in FIG. Therefore, the engaging portion 841 of the lock release lever 84 will not be inadvertently engaged with the pin 891 of the flywheel 89, and the regeneration operation can be performed stably. Further, at the end of the tape, the impact of the pin 891 causes the lock release lever 84 to have a rotation stroke sufficient to reliably engage the engaging portion 841 of the lock release lever 84 and the pin 891 and to slide the lock plate 76. The lock release lever 84 is moved to a position where it can be released, that is, the pin 100 is positioned at the right end of the elongated hole 842 in FIG.
It is possible to perform a reliable automatic stop.

Furthermore, the automatic stop operation described above operates in the same way during recording.

Here, as explained earlier in Figure 4, ASO
The bent locking piece 463 formed on the extending portion 462 of the lever 46 is connected to the elongated hole 592 of the regeneration operation slider 59.
It faces an inclined portion 597 formed in the. When the tape is stopped running, as shown in FIG. 28a, the inclined portion 597 of the playback operation slider 59
is engaged with a bent locking piece 463 of the ASO lever 46, and the ASO lever 46 is prevented from rotating about the shaft 305.

Further, in the tape playback state, as shown in FIG. 28b, since the playback operation slider 59 moves in conjunction with the operation of the playback operator 16, the inclined portion
7 is released from the bent locking piece 463 of the ASO lever 46, and the ASO lever 46 becomes rotatable and automatic stopping operation becomes possible.

Further, in the fast forwarding and rewinding states, as shown in FIG.
3 is engaged, the ASO lever 46 is no longer rotated, and automatic stopping is not performed.

Also, a review state obtained by operating the rewind operator 18 in the tape playback state will be explained. That is, as shown in FIG. 29a, the connecting lever 85
The locking portion 851 is connected to the protruding piece 4 of the ASO lever 46.
It is facing 64. For this reason, the rewind operator 1
8, as shown in FIG.
5, and the connecting lever 85 is rotated in the direction of arrow P in the figure. Then, the locking portion 851 of the connecting lever 85 engages with the protruding piece 464 of the ASO lever 46, preventing the ASO lever 46 from rotating and preventing automatic stopping.

Furthermore, in the tape playback state, the fast forward operator 17
Similarly, the queue state caused by operating the button will not be automatically stopped. That is,
When the fast-forward operation element 17 is operated, the bending locking piece 663 of the fast-forward operation slider 66 rotates the connecting lever 85 in the direction of arrow P in FIG. 29b. Therefore, the locking portion 851 of the connecting lever 85 engages with the protruding piece 464 of the ASO lever 46, and the ASO lever 4
6 is prevented from rotating.

In other words, automatic stop is performed only during recording and playback mode, and other modes such as fast forward, rewind,
Automatic stopping is not performed in the queue and review states.

Therefore, the rotation of the ASO lever 46 is prevented in fast forward, rewind, queue, and review conditions, so-called high-speed tape running conditions, and the ASO lever 46 is rotatable and automatically stopped in recording and playback conditions, so-called constant tape running conditions. Therefore, it is possible to prevent the automatic stop from malfunctioning.
In other words, in the automatic stop mechanism as described above, if the ASO lever 46 is made rotatable even when the tape is running at high speed, if the tape runs at high speed, it may be inadvertently caused by the vibrations and the tape pulling force during winding.
This causes the inconvenience that the ASO lever 46 rotates and automatically stops. For this reason, the ASO lever 46 is made rotatable only when the tape is running at a constant speed with relatively weak vibrations and tape pulling force during winding, thereby preventing the automatic stop from malfunctioning.

Next, the governor circuit portion will be explained.
That is, as shown in FIG. 30, the DC voltage +B
The power supply terminal 101 to which the voltage is applied is connected to the switch 7
2, adjust the tape playback speed to 1.2 [cm/
sec] or 2.4 [cm/sec] (double speed). This changeover switch 21 and both fixed contacts 212,
213 are connected to each other via resistors R ₁ and R ₂ , respectively, and the connection point thereof is connected to one power supply end of the motor 37 . Also, resistor R ₁ and
The connection point with R ₂ is connected to the movable contact piece S ₁₁ of the switch S ₁ which is interlocked with the fast forward and rewind operation sliders 66 and 77. This switch _S1 normally has its movable contact piece _S11 in contact with the fixed contact piece _S12 ,
The fast forwarding and rewinding operation sliders 66 and 77 are interlocked with each other and are brought into contact with the fixed contact piece _S13 .
The fixed contact piece S ₁₃ of the switch S ₁ is connected to the power supply terminal 101.

The fixed contact piece _S12 of the switch _S1 is connected to the emitter of a PNP transistor _Q1 , and is connected to a capacitor _C1 , a resistor _R3 , and a switch for increasing the tape playback speed by 10% compared to normal speed. The switch 7 is connected to the switch 7 via the switch 201 in series.
2 and the changeover switch 21. Furthermore, the base of the transistor Q ₁ is connected to the connection point between the capacitor C ₁ and the resistor R ₃ , and is also connected to the other power supply terminal of the motor 37 via the resistor R ₄ . In addition, the base of the transistor Q ₁ is connected to a resistor connected in parallel after passing through a diode D ₁ and a resistor R ₅ of the polarity shown in the figure in series.
It is connected to the connection point between the switch 72 and the changeover switch 21 via R ₅ and R ₇ . moreover,
The connection point between the diode D ₁ and the resistor R ₅ is the movable contact of the switch S ₂ which is linked to the changeover switch 21.
Connected to S ₂₁ . Both fixed contacts S ₂₂ and S ₂₃ of this switch S ₂ are connected to the other power supply terminal of the motor 37 via variable resistors R ₈ and R ₉ and resistors R ₁₀ and R ₁₁ in series, respectively. Note that a capacitor C ₂ is connected between both power supply terminals of the motor 37.

Here, the collector of the above transistor _Q1 is
It is connected to the base of NPN transistor _Q2 and is grounded via resistor _R12 . The collector of this transistor _Q2 is connected to the base of an NPN type transistor _Q3 , and is also connected to the connection point between the switch 72 and the changeover switch 21 via a resistor _R13 . Further, the base of the transistor _Q3 is connected to the base of the transistor _Q2 via a capacitor _C3 . Furthermore, the emitters of both transistors Q ₂ and Q ₃ are both grounded. Also, transistor Q ₃
The collector of is connected to the other power supply terminal of the motor 37.

Furthermore, the switch 72 and the changeover switch 21
A switch 202 is connected between the connection point between the resistors R ₁ and R 2 and the connection point between the resistors R 1 and R ₂ for slowing down the tape playback speed by 10% compared to normal speed. Although the switches 201 and 202 are shown separately in FIG. 30 for simplicity, they are used as the changeover switch 20 shown in FIG. 1 to selectively turn on each other.

If the playback operator 16 is now operated, the switch 72 is turned on. At this time, the changeover switch 21 and the switches S ₁ , S ₂ , 201, 202
Suppose that is in the position shown. Then, power terminal 1
After passing through the switch 72, the changeover switch 21 and the resistor _R1 , the DC voltage +B of 01 is applied to the transistor _Q1.
and the motor 37. At this time, transistor Q ₁ is supplied with a base bias voltage defined by variable resistor R ₈ and resistor R ₁₀ , and
Q ₁ and is controlled to apply a divided voltage to the motor 37 that causes the tape to run at 1.2 [cm/sec]. Moreover, even if the DC voltage +B changes, a stable DC voltage is always supplied to the motor 37, and the rotation speed of the motor 37 is always constant.

Further, when the movable contact 211 of the changeover switch 21 is switched to the fixed contact 213 side, the movable contact S ₂₁ of the switch S ₂ is also connected to the fixed contact S ₂₂ in conjunction with this. Therefore, the transistor Q ₁ is supplied with a base bias voltage defined by the variable resistor R ₉ and the resistor R ₁₁ , and the transistor Q ₁ is connected to the motor 3.
7 is controlled so as to apply a partial voltage that causes the tape to run at 2.4 [cm/sec]. This increases the tape constant running speed to 1.2 [cm/cm/
sec] and 2.4 [cm/sec] (double speed).

In addition, the changeover switch 21 and switch _S2 are
Assume that the switch 201 is turned on in the state shown in FIG. Then, resistor R ₃ causes transistor Q ₁
Since the emitter bias voltage of is specified, transistor Q ₁ controls the tape running speed of 1.2 to the motor 37.
It is controlled to apply a divided voltage that causes the vehicle to travel 10% faster than [cm/sec] as a standard. On the other hand, when the switch 202 is turned on, the transistor Q ₁ causes the motor 37 to set the tape running speed to 1.2 [cm/sec] as a reference.
It is controlled to apply a divided voltage that makes the vehicle run 10% slower. Also, increase the tape running speed.
Even when the speed is set to 2.4 [cm/sec], the tape running speed can be similarly increased by 10 [%].

Furthermore, when the fast forward and rewind operation elements 17 and 18 are operated, the fast forward and rewind operation slider 6
6, 77, movable contact piece S ₁₁ of switch S ₁
contacts the fixed contact piece _S13 . Therefore, the DC voltage +B of the power supply terminal 101 is directly applied to the motor 37, causing the motor 37 to rotate at a high speed, and the motor is in a high speed running state.

Here, the switch _S1 is not only switched in conjunction with the fast forward and rewind operation sliders 66, 77, but also in conjunction with the ASO lever 4 as shown in FIG.
It can also be switched in conjunction with the rotational movement of 6. In other words, the movable contact piece S ₁₁ of switch S ₁
are engaged with engagement pieces 465 and 466 that stand upright near the shaft 461 of the ASO lever 46. Although FIG. 31 shows two movable contact pieces _S11 , they are connected to each other within the switch _S1 and are actually a single electrode. Here, as mentioned earlier, under normal tape running at constant speed,
Since the ASO lever 46 is biased in the direction of arrow E in the figure, its engagement piece 465 presses the movable contact piece _S11 and connects it to the fixed contact piece _S12 . Then, when the tape reaches the end, the ASO
Since the lever 46 is rotated in the direction of arrow S in the figure,
The engagement piece 466 presses the movable contact piece _S11 and is connected to the fixed contact piece _S13 .

The switch _S1 is attached to the printed wiring board 102 and attached to the lower surface of the main chassis 30, as shown in FIG. A through hole 10 formed in this printed wiring board 102
3, the engagement pieces 465, 466 of the ASO lever 46
is inserted through and engaged with the movable contact piece _S11 .

Therefore, when the ASO lever 46 is rotated in the direction of the arrow S in FIG. ₃₁ , the movable contact piece _S11 of the switch S1 is connected to the fixed contact piece _S13 , so that The DC voltage +B of the power supply terminal 101 is applied to the motor 37, and the motor 37 is rotated with a larger rotational torque than when the tape is running at a constant speed. For this reason, pin 8 of flywheel 89
The force with which the lock plate 91 hits the engaging portion 841 of the lock release lever 84 can be increased, and the lock plate 76 can be reliably slid and unlocked.

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

Therefore, as detailed above, according to this invention, it is possible to easily attach the operator and the operation slider that moves each movable member of the tape recorder mechanism to a predetermined position in conjunction with the operation of the operator. Therefore, it is possible to provide an extremely good tape recorder operator mounting mechanism that has a simple structure and can be easily and accurately mounted.
