Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape cassette adapter used, for example, when a tape cassette smaller than a standard type is installed in a standard type recording/reproducing machine. When the tape is fed out to form a predetermined tape path, by preventing the tape from being excessively fed out due to the tape feeding force, the tape path formation is accurate and the tape path is not distorted. To provide an adapter for a tape cassette that does not cause an accident such as a loading pole, a capstan, etc. on the recording/reproducing machine side hitting the tape and damaging the tape because the tape cassette mounting adapter is attached to the recording/reproducing machine.

If you want to use a small tape cassette used in a recording/playback device such as a video tape recorder in a recording/playback device that is larger than this small tape cassette, for example, a standard type tape cassette, you need to use a small tape cassette. You will need an adapter to convert it to a standard tape cassette. This adapter may simply serve as a housing nog if the tape path of the small tape cassette is configured the same as that of a standard tape cassette; Although it is small, it is not that small because it is the same as the tape path of a standard type tape cassette. Therefore, in order to make the small tape cassette substantially smaller, for example, the supply side IJ-
The distance between the tape cassette and the take-up reel is smaller than that of the standard type, and the compact tape cassette configured in this way is used for recording and playing back on a standard type recording/playback machine. The tape path must be changeable to accommodate standard types of recording/playback equipment.

The present application has been made in accordance with the following objectives, and examples thereof will be described below.

FIG. 1 is a perspective view of a tape cassette that is smaller than a standard type tape cassette used in, for example, a standard type recording/reproducing machine, with its front lid open.

In the figure, A is a small cassette, and this small cassette l-
The frame body A consists of an upper half 1, a lower half 2, and a front cover 3 for protecting the tape, and the front cover 3 is rotatably attached to the upper part of the front side of the upper half 1 by a support shaft 4. .

One end of the sliding piece 7, which is held so as to be able to slide in the groove by being pressed by a substantially U-shaped spring 6 inserted into a groove 5 bored in the side surface of the upper half 1, is attached to the front cover 3. When the front lid 3 is in the closed state, the front lid 3 is maintained in that state, and when the front lid 3 is opened, the open state is maintained.

Inside the small cassette A are a supply reel 8 and a take-up reel 9.
The distance between the supply reel 8 and the take-up reel 9 is equal to the distance between the supply reel disk and the take-up reel disk of a standard type recording/reproducing machine that cannot be installed only with this small cassette A. The distance between them is shorter than the distance between them. Further, the magnetic tape 1o is arranged such that it runs along a predetermined running path between the supply reel 8 and the take-up reel 9. That is, the magnetic tape 10 is wound onto the take-up reel 9 from the supply reel 8 through the guide poles 11 and 12. An uneven groove is formed on the lower surface of the lower flange of the supply side reel 8, and an uneven groove is also formed at a predetermined position of the lower half 2 corresponding to the uneven groove of the lower flange. The supply reel 8 is urged toward the lower half 2 by the action of the plate pie attached to the reel 8, and the concave and convex grooves engage with each other, and the supply reel 8 is fixed and wound around the supply reel 8. Prevents the magnetic tape from loosening. Lake, small cassette A
When the reel 8 is mounted on the recording and reproducing machine, the supply reel 8 is lifted by the supply reel disk of the recording and reproducing machine over a specified amount against the repulsive force of the plate pie on the side of the plate 1, and the uneven grooves are raised against each other. The mesh is released and rotation becomes possible. That is, in the lower half 2 at the position corresponding to the supply reel 8,
A hole 13 for inserting the supply reel disk of the recording/reproducing machine is formed, and the supply reel disk is inserted into the supply side reel 8.
will be inserted into. Further, the take-up reel 9 is inserted into a shaft 14 fixed to the lower half 2, and can rotate around this shaft 14.

A brake mechanism is provided to prevent the take-up reel 9 from rotating when the take-up reel 9 (Kid, small power cellar) A is not installed in the recording/reproducing machine. This brake mechanism consists of a brake that presses the upper surface of the peripheral edge of the lower flange 150 of the take-up reel 9. This brake is inserted into a shaft formed integrally with the lower half 2, and is pressed by the action of a spring. When the brake is pressed, a portion of the brake shoe comes into pressure contact with the 15 surface of the lower 7 flange,
The take-up reel 9 does not rotate so that the magnetic tape does not loosen. Furthermore, when the small cassette recorder) A is attached to a recording/reproducing device or an adapter described below, a force is applied that resists the repulsive force of the spring, and a part of the brake shoe separates from the lower flange 15 surface, causing the take-up reel 9 will be able to rotate. The rotation of the take-up reel 9 is performed by a driving force transmission medium that meshes with teeth 16 formed on the peripheral side surface of the lower flange 15 of the take-up reel 9, unlike the supply reel 80 system.

Therefore, when the small cassette (7) A is attached to the adapter for use in a recording/reproducing machine exclusively for this small cassette or a standard type recording/reproducing machine, the lower half 2 is attached so that the driving force transmission medium can mesh with the teeth 16. A notch 17 is formed.

Fig. 2 is a partial perspective view of a tape cassette adapter for using the small cassette in a standard type recording/reproducing machine, and Figs. 3 and 4 show a tape cassette adapter with one hinge removed. FIG.

In the figure, B is an adapter with an external shape that is almost the same as a standard type tape cassette.This adapter B consists of a front cover 30, -731 on the top, and -732 on the bottom, and accommodates the small cassette A. A storage section A' is configured. Further, a lid 33 is provided at the opening of this storage section A'.

Then, when the lid body 33 is opened and the small cassette A is attached to the storage section A' with the front lid 3 open, the contact piece of the switch 34 provided on the front side wall of the storage section A' will touch the small cassette. The small cassette A is suppressed by the rear part of the cassette A to be in the switched on state, and the small cassette A
When the lid 33 is closed after being attached, the lock part 3 of the lid 33
5 is fitted into and engaged with the four engaging portions 36 of the adapter B, and the contact piece of the switch 37 provided at the bottom of the engaging recess 36 is pressed so that it becomes sharp in the switch-on state.

That is, when the small cassette A is set in the storage section A' of the adapter B and the lid 33 is closed, the tape feeding mechanism described later is activated.

38 is a loading start button, and this loading start button 38 is a two-part switch 34°37
When pressed in the on state, the motor 39 is driven, and a little later than the start of driving of the motor 39, the motors 40 and 4 are activated.
1 is configured to be driven. Then, the tape feeding lever 42.4 is driven by the motor 40, 4.1.
3 rotates from the position shown by the solid line in FIG. 3 to the position shown by the solid line in FIG. 45, the tape is fed out to form a predetermined tape path, that is, a tape path substantially similar to the tape path of a standard type tape cassette.

The reason why the motor 39 is activated a little earlier than the motors 40 and 41 is to take into consideration the case where there is slack in the tape before the tape loading knob. If there is slack in the tape, turn the winding reel 9 of the small force roller A in the tape winding direction to wind the tape onto the winding reel 9. be.

The motor 40 is mounted on a mounting plate 46 having a cross-sectional shape, and the motor shaft of the motor 40 is inserted into a hole in the upright portion of the mounting plate 46 and is attached to the motor shaft of the motor 40. Since the worm 47 is attached, the gear 48 meshing with the worm 47 is rotated by the drive of the motor 40, and one end is connected to the gear 48 by rotation of the gear 48 in the counterclockwise direction in FIG. Move the bar 49 that is attached downward.

FIG. 5 is an explanatory diagram of the mechanism around the motor 4-0,
The bar 49 is composed of a lower bar 49' and an upper bar 49'', and the lower bar 49' is provided with pinots 50, 51, and the pins 50, 51 are inserted into the holes of the upper bar 49''. 52 and 53, one end side of the bar 49 "two-part bar 49" is rotatably attached to the pin 54 implanted on the gear 48, and the lower bar 49' of the bar 49 It is rotatably attached to a bottle 56 implanted in the rotating body 55 on the other end side, and the pinot 50
Since the coil spring 57 is attached between the rotating body 55 and the gear 48,
The upper bar 49'' and the lower bar 49' are pulled together.Then, the bar 49
When moved downward in the figure, the rotating body 55 rotates counterclockwise, and the tape feeding lever 42, which is integrally formed with the rotating body 55, is rotated to a stop position by the stopper 58. That is, the tape feeding lever 42 is displaced from the state shown in FIG. 3 to FIG. 4 by the drive of the motor 40, and the tape is fed out from the small cassette A.

At this time, one end of the bar 49 supported by the bin 54 is at point A1 in FIG. 4! 7A2 point position is reached, and then A3 point position is reached while resisting the tensile force of the coil spring 57. When the A3 point position is reached, the bar 49 in FIG. Since the gear 48 is configured to be located on the right side, even if one drive of the motor 40 is stopped due to the tensile force of the coil spring 57, the gear 48 will not rotate in the opposite direction.

The motor 40 is configured such that the tape feeding lever 42 is
In the state shown in the figure, the pin 59 implanted downward from the bottom of the gear 48 separates from the switch 60 and comes into pressure contact with the switch 61, at which point the motor 40 stops.

The motor 41, which is the drive source for rotating the tape feed lever 43, operates at the same time as the motor 40, somewhat later than the operation of the motor 39, but this motor 41 is not attached to the mounting plate 62, and the motor A rotational force is applied to the gear 64 from the worm 63 attached to the motor shaft of the tape feed bar 43, and the tape feed bar 43 is rotated.

Note that this gear 64 is rotatably supported by a mounting plate 65.

FIG. 6 is an explanatory diagram of the mechanism around the gear 64, in which one end of the bar 67 is connected to the pin 66 implanted in the gear 64, and the other end of the bar 67 is connected to the base of the tape feeding lever 43. They are rotatably attached to implanted pins 68, respectively. This bar 67, like bar 49, has a lower bar 67
' and the upper bar 67'', and the pin 69.70 implanted in the lower bar 67' is connected to the hole 7 bored in the upper bar 67''.
1, 72, and is polymerized with an E ring. or,
Coil springs 73 are installed in pinots 66 and 69. However, when the bar 67 is in the state shown in FIG. 3, this coil spring 73 exerts no spring force at all.

The driving force from the gear 64 is transmitted to the tape feeding lever 43 via the bar 67, and the tape feeding lever 43 is connected to the ceiling portion of the upper half 31 of the adapter B and the lower half portion at the base portion. The pin 66 of the gear 64 is rotatably supported at the bottom of the gear 84 shown in FIG.
When the tape reaching point B2 is reached, the tape feeding lever 43 is also moved to a predetermined position, and the tape is fed out from the small cassette A by the guide roller 45 provided at the tip of the tape feeding lever 43, and the tape of the standard type tape cassette is fed out. A tape path that is substantially the same as the tape path is now formed, and at this point the guide roller 45 is positioned by the stopper 74.

Furthermore, the gear 64 resists the spring force of the coil spring 73 from point B2 due to the driving force of the motor 41, and stops at point 83. That is, the pinot 75 provided below the gear 64 shifts from the contact state with the switch 76 to the contact state with the switch 77, and the drive of the motor 41 is stopped. Note that this motor stopping mechanism is similar to the stopping mechanism of the motor 40.

The gear 64 stops at the 83rd point, but in this state, that is, in the state shown in FIG.
Since the bar 67 is configured to be located below the imaginary line connecting the pin 68 and the pivot point of the gear 64, the spring force of the coil spring 73 will not cause the gear 64 to rotate in reverse. That is, the biasing mechanism for the gear 64 is also constructed in the same manner as the biasing mechanism for the gear 48.

Further, a lock arm 78 is provided which rotates according to the rotation of the gear 64, and locks the guide roller 45, which is driven by the rotation of the gear 64 and forms a predetermined tape path, in a predetermined position. .

In this locking mechanism, as shown in FIG. 7 in an exploded state, the lock arm 78 has an accommodating portion 79 having a substantially U-shaped cross section, and a lever 81 equipped with a rectangular coil spring 80 is mounted in the accommodating portion 79. One end of the torsion coil-bye 80 is engaged with the groove 82 of the accommodation portion 79, and the other end is engaged with the side wall of the lever 81. In this state, the pin 83 is inserted through the holes of the lock arm 78 and the lever 81, and the lock arm 78 and lever 81 are rotatably held on the ceiling of the adapter. Similarly, this pin 83 is attached to the ceiling by screwing into a hole 85 made in the head 84.

A pin 86 is provided on the lever 81.
The pin 66 of the gear 64 is loosely fitted into a long hole 88 formed at one end of the connector 87, and the pin 66 of the gear 64 is loosely fitted into a hole 89 formed at the other end of the connector 87. Further, one end of a coil spring 90 is attached to the lever 81, and the other end of the coil spring 90 is attached to a pin planted in the ceiling of the adapter. The center is biased counterclockwise. The lever 81, which is biased by the same force, is positioned by a pin 91.

Then, as shown in FIG. 4, the pin 66 of the gear 64 is set to B1.
When reaching point B2 from point B2, the tape feeding lever 43 changes from the state shown in FIG. 3 to the state shown in FIG. 4, and the guide roller 45 comes into contact with the stopper 74. Since the connector 87 and the lever 81 are connected to each other by the elongated hole 88 and the pin 86, the lock arm 78 does not operate, and from the moment the pin 66 passes the point B2, the lock arm 78 moves against the force of the coil spring 90. When the pin 66 reaches a point in front of the final position 83, the lock arm 78 holds the guide roller 45 from the outside, and when the pin 66 reaches the 83rd point, the lock arm 78 rotates clockwise. Accordingly, the cover 87 moves against the torsion coil spring 80 and presses the lock arm 78 against the guide roller 45.

Moreover, when the motor 39 operates in the state shown in FIG.
The rotational force of the motor 39 is transmitted to the roller 92, and...
This rotational friction force causes the holding member 93 of the roller 92 to rotate clockwise around the rotation shaft 94 of the motor 39,
The roller 92 and the rotating body 95 come into contact with each other, and the driving force is transmitted to the rotating body 95.

The rotational force of the rotating body 95 is transmitted to the gear 96 through a friction structure as shown in FIG.
The tape is transmitted to the take-up reel 9 to the small cassette through the gear 97 meshing with the gear 97 and the gear 98 integrally formed with the gear 97, so that the slack tape is taken up on the take-up reel 9. Become. Furthermore, when the tape is fed out from the small cassette A by the guide rollers 44 and 45 of the tape feeding lever, this driving force in the tape winding direction acts on the tape as a braking force in the opposite direction to the tape feeding direction. This prevents excess tape from being fed out even if the tape is pulled out forcefully. Further, this driving force in the tape winding direction is applied to the supply reel 8 of the small cassette A when the tape is pulled while the tape is wound to the maximum on the supply reel 8. The structure is such that a force that is somewhat smaller than the force that causes the supply reel 8 to spin idly against the applied brake is transmitted. This is designed to ensure that the tape is always fed out from the take-up reel 9 when the tape is fed out, and this friction structure is what controls this force. A gear 96 shown in FIG.
, and a spring 101 that presses this rotary body 95 in cooperation with an annular body 100, so that even when the tape is fed out to a predetermined position, the tape resists the braking force of the supply reel 8. The friction 7 torque is set so that the winding side reel 9 does not wind up.

Since this motor 39 is configured to stop after the motors 40 and 41 stop, the guide roller 4
4.45, the motor 39 is stopped after a predetermined tape path is formed, and the roller 92 is rotated counterclockwise by the force of the spring 102 and separated from the rotating body 95. Therefore, after a tape path that is approximately the same as that of a standard type tape cassette is formed, even if this adapter is attached to a standard type recording/playback machine and the recording/playback machine is operated, the recording/playback will not be possible. The take-up side reel disk of the machine is fitted into the guide hole 103 of the gear 96,
Even if the driving force of the take-up side reel disk is transmitted, since the roller 92 and the rotating body 95 are separated from each other, no braking force is applied.

Guide hole 1 into which the reel tiff on the winding side of the recording/reproducing machine fits
An annular recess 104 is formed in the ceiling of the adapter B in which the gear 96 having the number 03 is disposed, and the gear 96 is structured to be able to move somewhat within the range of the annular recess 104. The gears 97 and 98 that transmit the driving force to the winding side wheel 9 are the annular body 1 which is rotatably loosely fitted to the non-gear side wall of the gear 96 via a bearing 105.
06, and is adapted to move with the movement of the annular body 106.

Father, this gear 98 is rotatably attached to one end of a sliding plate 107, and the other end of the sliding plate 107 is the winding side of the small cassette A installed in the adapter storage section. It is rotatably attached to an adapter at a position corresponding to the rotational axis position of the reel 9. For example, even if the gear 96 is displaced, the gear 98 meshes with the take-up reel and the gear 97 is meshed with the gear 96,
The driving force of the reel disk on the take-up side of the recording/reproducing machine is reliably transmitted to the IJ-rule 9 on the take-up side.

The gear 96 is loosely engaged with an annular portion 109 provided at one end of the base portion 108 to which the motor 39 is attached, and the bearing 105 and the annular body 106 are located in the loosely engaged portion. It is press-fitted and held in place. Furthermore, the movement of this gear 96 is mainly centered around the spindle 110 in the vertical direction in FIG. move in conjunction with each other around these support shafts 110 and 111, and this movement also causes the annular recess 1
It is regulated by the periphery of 04.

The motor 39 is attached to the base portion 108, and the rotation shaft 94 of the motor 39 hangs down from the base hole 112. A holding member 93 is rotatably attached to this rotating shaft 94, and a recess 113 of this holding member 93
The shaft of the roller 92 is disposed in the roller 92, and the roller 92 is in pressure contact with the rotating shaft 94, and as described above, the roller 292 is rotated by the rotational friction force. As shown in FIG. 9, the roller 92 is attached by a bottle 114 passing through the lower part of the roller 92 and suspended horizontally on the side wall of the recess 113, and furthermore, a spring 115 is provided on the bottle 114. A spring force is applied to the protrusion 116 formed at the bottom of the recess 113 and the lower part of the roller 92, and with this configuration, the roller 92 is pressed against the rotating shaft 94. 117d'' is the opening of the recess 113 and facilitates attachment of the roller 92.

When the adapter B is configured as described above, the loading operation is as follows: open the lid 33 of the adapter B, open the front lid 3 of the small cassette A, attach it to the storage section A', and then load the lid. Close the body 33. Then switch 34.3
7 is turned on, the motor 39 is operated, and the roller 92, which is in pressure contact with the rotating shaft 94 of the motor 39, comes into contact with the rotating body 95 due to the rotation of the holding member 93, and the gear 96.
The driving force of the motor 39 is transmitted to the take-up reel 9 through 97 and 98, and the take-up reel 9 winds up the tape that is rotated L1 in the tape winding direction.

When the loading start button 38 is pressed to turn it on, the motor 40 operates, and the driving force is transmitted to the rotating body 55 via the gear 48 and the bar 49, causing the tape feeding lever 42 to rotate. The tape in the small cassette will now be fed out. Then, the tape feeding lever 42 rotates at the predetermined position 1, hits the stopper 58, and stops. However, the gear 48 continues to rotate in the same direction even after the tape feed lever 42 stops, and the bin 59 comes into contact with the switch 61, at which point the motor 40 stops.

Simultaneously with the operation of the tape feeding lever 42, the motor 41 is also operated by pressing the loading start button 38, and the driving force is transmitted to the tape feeding lever 43 via the gear 64 and the bar 67, and the tape feeding lever 43 is moved to a predetermined position. It rotates until it hits a stopper 74 and stops. However, the gear 64 rotates while further extending the coil spring 73, and the lock arm 7
8 to rotate the guide roller 4 of the tape feeding lever 43.
Lock arm 7 is applied by the force of torsion coil spring 8o to 5.
8 will be crimped. Similarly, after this crimping operation, the pin 75 of the gear 64 comes into contact with the switch 77, and at this point the motor 41 stops.

In this state, the tape of the small sumo wrestler Tsu I-A is fed out by the guide roller 44.45 of the tape feeding lever 42.43, and the tape path is approximately the same as that of a standard type tape cassette.

Then, by stopping the motors 40 and 41, the motor 3
9 is stopped and the holding member 9 is provided with a roller 92.
3 is rotated by the force of the spring 102, and the roller 92
moves away from the rotating body 95 and stops at the stop.

At the end of the above operation, the tape has been fed out from the small cassette A and a predetermined tape path has been formed, and recording and playback can be performed by attaching this small cassette attachment adapter to the recording/playback device. Become.

After recording and reproducing, when the small cassette attachment adapter is taken out from the recording and reproducing machine and the unloading knob button 118 is pressed, the motors 40, 4.1 rotate in the opposite direction to the above case, and the motor 39 rotates in the same manner again. direction, the tape winding 1 drive force is applied to the winding reel 9, and the pin 59
．． 75 contacts switch 60.76, motor 40.75 contacts switch 60.76.
41 stops and motor 39 also stops, resulting in the same state as when the small cassette A was attached to the adapter B. Therefore, open the lid 33 of the adapter B and access the storage section A'.
A smaller cassette A can be taken out.

During the loading operation, the coil springs 57 and 73 and the stopper 58 keep the motors 40 and 41 operating for a while even after the tape is fed out by the tape feeding lever and a predetermined tape path is formed. This is to keep the guide roller in a predetermined position (only one) by .74, and the reason why the motor 39 is also operated is to take up any slack in the tape after forming the tape path. Similarly, during anano loading operation, the motor 39 is operated even after the guide rollers 44 and 45 are in the position shown in FIG. 3 to prevent tape slack. This is to ensure that the tape is completely wound onto the take-up reel 9.

FIG. 10 is an explanatory diagram of another embodiment of the tape cassette adapter. In the figure, the same numbers as in FIGS. 2 to 9 have the same structure.

In the adapter of the above embodiment, the brake force is immediately released when the operation of the tape storage mechanism stops, and there is a risk that the tape may loosen if some impact force is applied to the adapter with a small cassette placed therein. In this embodiment, the braking force is always applied, so there is no such drawback.

That is, the roller 92 disposed on the holding member 93 is -
i is biased clockwise by the force of a spring 120 whose other end is stretched over the pin 119 and the holding portion side 93;
It is always in contact with the rotating body 95. Since the roller 92 is in contact with the rotation direction of the rotating body 95 in which the tape is fed out, a braking force is always applied within a range that does not exceed the frictional force of the friction clutch, so that the tape does not loosen. ing.

This braking force is generated when the adapter B is attached to the recording/playback machine, and the protrusion 122 of the brake lever 121 is pressed against the reel brake release partner on the winding side of a standard type tape cassette provided on the side of the record/playback machine. Brake lever 1
21 is rotated clockwise around the support shaft 123, the holding member 93 is pressed counterclockwise by the tip of the brake lever, and the roller 92 and the rotating body 95 are separated and released.

Similarly, when the adapter is not attached to the recording/reproducing device, the brake lever 121 is biased counterclockwise by the force of the spring 124, and the brake lever 121 is biased counterclockwise by the force of the spring 124.
is apart from the holding member 93. Further, the spacing between the holding member and the brake lever is such that the holding member and the tip of the brake lever do not come into contact with each other even when the base portion 108 in FIG. 10 moves in one direction. It is.

As mentioned above, the tape cassette adapter according to the present invention is an adapter used when a tape cassette smaller than a standard type tape cassette is attached to a standard type recording or reproducing machine, and is used when the tape cassette is attached to a standard type recording or reproducing machine. The tape storage means is provided with a tape feeding means for feeding the tape to a predetermined position from a small tape cassette, and a tape storage means for storing the fed tape in the small tape cassette, and the tape storage means is activated in response to the operation of the tape feeding means. Since the tape storage means acts on the tape when the tape is fed out by the tape feeding means, a predetermined tape path can be formed smoothly and accurately. Sometimes the tape is fed out more than necessary due to the tape tension, causing slack in the tape bus. It has the advantage of eliminating accidents such as damage to the tape.
