Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape winding adapter, and in particular to a small tape cassette attached to a tape cassette adapter that is used by attaching a tape cassette smaller than a standard type to a standard type recording/reproducing machine. The first reel connected to the supply reel of
A reel disk is provided, and a second reel disk is connected to a gear of a tape cassette adapter that meshes with a gear portion of a take-up reel of a small tape cassette. By providing a drive mechanism that drives in the tape winding direction and a mechanism that automatically stops this drive mechanism when the end of the tape is detected, for example, when playing a small tape cassette, the playback point of the tape can be adjusted. Even if the desired one or more is desired, it can be done with a simple device without having to be installed in a recording/reproducing machine one by one. Therefore, information can be recorded on multiple tape cassettes, and these multiple tape To provide a tape winding adapter which allows smooth reproduction even when it is desired to reproduce only a specific part of information recorded on a cassette.

The applicant has previously proposed a recording/playback device that is smaller than the standard type, and a tape cassette that is smaller than the standard type tape cassette used with this recording/playback device. We have proposed a tape cassette adapter that has approximately the same external shape as a standard type tape cassette, taking into consideration compatibility so that it can be used with a standard type recording/reproducing device.

Then, a small tape cassette is attached to this kind of miniaturized portable type recorder for recording, and this small tape cassette is attached to a tape cassette adapter, and this is used for recording and playback of a standard type of stationary type. You can record TV programs, etc. on a small tape cassette using a small recording/playback device via a tuner, and then use a tape cassette adapter to connect to a standard type recording/playback device installed at another location. It is expected that the number of cases where players will play the game by wearing them will increase significantly.

In such a usage pattern, it is thought that the number of cases where it is desired to sequentially reproduce only a desired portion of a plurality of tape cassettes will increase. In such cases, if you had to attach the tape cassette to an adapter, attach it to the recording/playback device, and then search for the necessary location, it would take a lot of time to prepare, and this would prevent smooth playback. Therefore, the enjoyment of playback is halved.

In other words, due to the short tape length of small tape cassettes, it is often necessary to split into multiple tape cassettes when recording a series of information, and in such cases, each small tape cassette is If a tape cassette had to be loaded into a recording/playback machine and rewound each time, it would take too much time to prepare for playback, making small tape cassettes difficult to use.

The present invention obviates the above-mentioned drawbacks and allows compact tape cassettes to be used very simply.

FIG. 1 is a perspective view of a tape cassette for a video tape recorder, which is smaller than a standard type tape cassette for use 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 of A consists of an upper nozzle 1, a lower nozzle 2, and a front cover 3 for protecting the tape. Possibly installed. 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.

(small force cera) Inside A are the supply side reel 8 and the take-up side 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 the Further, the magnetic tape 10 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 from the supply reel 8 to the take-up reel 9 via the guide poles 11 and 12. An uneven groove is formed on the lower surface of the lower flange of the supply side reel 80, and an uneven groove is also formed at a predetermined position on the lower flap 2 corresponding to the uneven groove on the lower flange. The supply reel 8 is urged toward the lower half 2 by the action of the leaf spring attached to the supply 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. When the small cassette A is installed in a recording/reproducing machine, etc., the supply reel 8 is filled with a specified amount of half 1 by the supply reel disk of the recording/reproducing machine, etc.
It is lifted to the side against the repulsive force of the leaf spring, and the grooves are disengaged from each other, allowing rotation. That is,
A hole 13 for inserting a supply reel disk of a recording/reproducing machine is formed in the lower half 2 at a position corresponding to the supply reel 8, so that the supply reel disk can be inserted into the supply reel 8. . Further, the take-up reel 9 is inserted into a shaft 14 fixed to the lower half 2, and this shaft 1
It can be rotated around 4.

A brake mechanism is disposed on the take-up reel 9 so that the take-up reel 9 does not rotate when the small cartridge A is not attached to the recording/reproducing machine. This brake mechanism consists of a brake that presses the upper surface of the peripheral edge of the lower flange 15 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. In the energized state, a portion of the shoe of the brake comes into pressure contact with the surface of the lower flange 15, so that the take-up reel 9 does not rotate and the magnetic tape does not loosen. When the small cassette A is attached to a recording/reproducing machine or a tape cassette adapter described later, a force is applied that resists the repulsive force of the spring, and a part of the brake shoe is separated from the lower flange 15 surface, causing the take-up reel 9 will be able to rotate. Rotate take-up reel 9, supply reel 8
Unlike the above method, this is carried out using 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. Therefore, when the small cassette A is attached to an adapter for use in a recording/playback machine exclusively for this small cassette or a standard type recording/playback machine, tooth 1
A notch 17 is formed in the lower half 2 so that a driving force transmission medium can mesh with the lower half 6.

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 the tape cassette adapter with the second nozzle removed. FIG.

In the same figure, reference numeral B denotes an adapter with an external shape that is approximately the same as that of a standard type tape cassette. l-
A storage section A' is configured to store A.

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. It is configured to be turned on by being pressed by the back part of A, 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 engagement recess 36 of the adapter B, and the contact piece of the switch 37 provided at the bottom of the engagement recess 36 is pressed to turn on the switch.

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 when this loading start button 38 is pressed with the switch 34°37 on, the motor 39 is driven, and a little later than the start of driving of the motor 39, the motor 40, 4
1 is configured to be driven. The tape feeding levers 42 and 43 are then driven by the motors 40 and 41.
rotates from the solid line position in FIG. 3 to the solid line position in FIG. The tape is fed out by 45,
A predetermined tape path, that is, a tape path substantially similar to the tape path of a standard type tape cassette is formed.

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 loading the tape. This is to allow the take-up reel 9 of the small cassette A to be rotated in the tape winding direction to wind up the tape on the take-up reel 9 if there is slack in the tape.

The motor 40 is mounted on a mounting plate 46 having a disconnected circuit 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 mounted. Since the worm 47 is attached to the shaft,
The drive of the motor 40 rotates the gear 48 meshing with the worm 47, and the counterclockwise rotation of the gear 48 in FIG. 3 causes the bar 49, one end of which is connected to the gear 48, to move downward. .

The bar 49 is composed of a lower bar and an upper bar, and the lower bar is provided with a pin, which is loosely fitted into the holes 52 and 53 of the upper bar. One end is rotatably attached to a pin 54 implanted on the gear 48, and the other end of the lower bar of the bar 49 is rotatably attached to a pin 56 implanted in a rotating body 55. and pin 5 on the bottom bar.
Since a coil spring 57 is installed between 4 and 4,
The bar 49 connecting the rotating body 55 and the gear 48 is configured such that its upper bar and lower bar are pulled together. When the bar 49 is moved downward in FIG. 3, the rotating body 55 rotates counterclockwise, and the stop position of the tape feed lever 42, which is integrated with the rotating body 55, is changed by the bust buckle 58. It will now be rotated.

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 pinot 54 reaches the point A2 from the point A in FIG. 4, and further reaches the point A3 while resisting the tensile force of the coil spring 57. When the A3 point position is reached, the positional relationship of the bar 49, that is, the bar 49 in FIG. Since the gear 48 is configured to be located on the right side, the gear 48 will not rotate in the opposite direction even if the driving of the motor 40 is stopped due to the tensile force of the coil bypass 57.

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 a driving source for rotating the tape feeding lever 43, starts operating the motor 40 a little later than the operation of the motor 39.
The motor 41 is attached to the mounting plate 62, and rotational force is transmitted from the worm 63 attached to the motor shaft of the motor 41 to the gear 64, which causes the tape feeding lever 43 to move. Rotation is performed. Note that this gear 64 is rotatably supported by a mounting plate 65.

One end of a bar 67 is rotatably attached to a pin 66 embedded in the gear 64, and the other end of the bar 67 is rotatably attached to a pin 68 embedded in the base of the tape feed lever 43. . Like the bar 49, this bar 67 consists of a lower bar and an upper bar, and a pin implanted in the lower part is loosely fitted into holes 71 and 72 drilled in the upper part. In addition, a coil 73 is attached to the pin 66 and the pin implanted in the lower bar; In the case of a state, no kuneka is working at all.

The driving force from the gear 64 is transmitted to the tape feeding lever 43 via the gear 67.
This tape feeding lever 43 is duffed at the base portion.

The pin 66 of the gear 64 moves from point B□ to point 81 as shown in FIG. Once reached, the tape feeding lever 43 also moves 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 is fed out from the tape tip of the standard type tape cassette. At this point, the guide roller 45 is positioned by the guide roller 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 until it reaches point 83 and stops. That is, the pin 75 provided on the lower side of the gear 64 moves from the contact state with the switch 76 to the contact state with the switch 77, and the driving 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 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, such a biasing mechanism for the gear 64 is configured similarly to 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, the lock arm 78 has a housing portion having a substantially U-shaped cross section, and this housing portion includes a torsion coil spring 80.
A lever 81 is housed, and a silicon coil spring 8
One end of the lever 81 is engaged with the groove of the housing portion, and the other end is engaged with the side wall of the lever 81. In this state, the pins are inserted into the holes of the lock arm 78 and lever 81, and the lock arm 78 and lever 81 are rotatably held on the ceiling of the adapter.

A pin 86 is provided on the lever 81, and this pin 86
6 is loosely fitted into an elongated hole 88 formed at one end of a connector 87, and a pin 66 of a gear 64 is loosely fitted into a hole formed at the other end of the connector 87. Further, one end of the U coil spring 90 is attached to the lever 81, and the other end of the coil spring 9o is attached to a pin planted in the ceiling of the adapter. In Figure 4, the force is applied counterclockwise. The lever 81c and the pin 91vc, which are biased by this biasing force, are used to position the lever 81c.

Then, as shown in FIG. 4, the pinot 66 of the gear 64 is B,
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 final position 83. The connector 87 is configured to move while resisting the I-siri coil spring 80 and press the lock arm 78 against the guide roller 45 when the connector 87 is rotated out of rotation.

Moreover, when the motor 39 operates in the state shown in FIG.
The rotational force of the motor 39 is transmitted to the row 292, and the holding member 93 of the roller 92 rotates clockwise around the rotation shaft 94 of the motor 39 due to the rotational frictional force between the roller 92 and the rotating body. 95 comes into contact with the rotating body 95, and the driving force is transmitted to the rotating body 95.

The rotational force of this rotating body 95 is transmitted to a gear 96 via a friction structure, and a gear 97 that meshes with this gear 96
Then, through the gear 98 formed integrally with the gear 97, the tape is transmitted to the take-up reel 9 of the small cassette 1-A, and the slack tape is wound onto the take-up reel 9. . Further, this driving force in the tape winding direction is applied to the tape from the small cassette A to the guide roller 44.4 of the tape feeding lever.
5, a braking force is applied to the tape in the opposite direction to the tape feeding direction, so that even if the tape is tried to be drawn out forcefully, excess tape is not fed out. In addition, this driving force in the tape winding direction is calculated when the tape is pulled while the tape is wound to the maximum on the supply reel 8 of the small force cera) A. 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 brake provided on the reel 8 is transmitted.

Since this motor 39 is configured to stop after the motors 40 and 41 stop, the guide roller 4
4.45, after a predetermined tape bus is formed, the motor 39 is stopped, 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 substantially the same as the tape path of a standard type tape cassette is formed, this adapter is connected so that the counting side reel disk is fitted into the gear 960 guide hole 103 and the take-up side reel disk is fitted. Even if the driving force is transmitted, the roller 92 and rotating body 95
Because it is far away from the brake, no braking force is applied.

An annular recess is formed in the ceiling of the adapter B in which the gear 96 is provided, in which the guide hole 103 into which the take-up reel disk of a recording/reproducing machine or the like fits is formed, and the range of this annular recess is The gear 96 is structured to be able to move somewhat freely within the winding reel 9, and the gear 97.9 can provide a driving force to the take-up reel 9.
8 is pivotally supported and attached to an annular body which is rotatably loosely fitted to the side wall of the non-geared part of the gear 96 via a bearing, and moves with the movement of the annular body.

Further, one end of a sliding plate 107 is rotatably attached to this gear 98, and the other end of the sliding plate 107 is attached to the take-up reel 9 of the small cassette A installed in the adapter storage section. For example, even if the gear 96 is displaced, the gear 98 will mesh with the take-up reel and the gear 97 will mesh with the take-up reel. It seems to be meshing with 96,
The driving force of the reel disk on the take-up side of the recording/reproducing machine is reliably transmitted to the reel 9 on the take-up side.

The gear 96 is loosely engaged with an annular portion provided at one end of the base portion 108 to which the motor 39 is attached, and the bearing and the annular body are press-fitted between this loosely engaged portion. Retained. Furthermore, the movement of this gear 96 is mainly centered around the support shaft 110 in the vertical direction in FIG.
1 as the center of the movement, and furthermore, these spindles 110,
111, and this movement is further restricted by the peripheral edge of the annular recess.

The motor 39 is attached to the base, but the rotation shaft 94 of the motor 39 hangs down from the base hole. A holding member 93 is rotatably attached to this rotating shaft 94, and a shaft of a roller 92 is disposed in a recessed portion of this holding member 93, and the roller 92 is in pressure contact with the rotating shaft 94. As described above, the roller 92 rotates due to the rotational frictional force.

Reference numeral 120 is a battery that is a rechargeable power source for the motors 39, 40, and 41.

When adapter B is configured as described above, the loady knob operation is as follows: first open the lid 33 of adapter B, then attach the small cassette A to the storage compartment A' with the front lid 3 of the small cassette A open; Close 33. Then switch 34.3
7 is turned on, the motor 39 is activated, 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 930, and the gear 96.
The driving force of the motor 39 is transmitted to the take-up side wheel 9 through 97 and 98, and the take-up side wheel 9 rotates in the tape winding direction to wind up the slack tape.

Then, when the Rope Ino Duster Start button 38 is pressed to turn on, the motor 40 operates, and the driving force is transmitted to the rotating body 55 via the gear 48 and the bar 49, rotating the tape feeding lever 42 and The tape in the cassette will now be fed out. Then, tape feed lever 4
2 rotates at a predetermined position, hits a 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 pin 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 a driving force is applied to the tape feeding lever 43 via the gear 64 and the bar 67. It rotates to the position and stops when it hits the stopper 74. However, the gear 64 rotates while further extending the coil spring 73, rotates the lock arm 78 via the connector 87 and lever 81, and the force of the torsion coil spring 80 causes the lock arm 78 to rotate on the guide roller 45 of the tape feed lever 43. The one who presses it roars. Furthermore, after this crimping operation,
Pin 75 of gear 64 contacts switch 77VC, and motor 41 stops at this point.

In this state, the tape to the small cassette is fed out by the guide rollers 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 stops and the holding part t19 where the roller 92 is provided
3 is rotated by the force of the spring 102, and the roller 92
moves away from the rotary body 95, hits the stopper and stops.

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, the small cassette mounting adapter is taken out from the recording and reproducing machine and rotated in the opposite direction to that described in the unloading description, and the motor 39 again rotates in the same direction to wind the tape winding 1 drive force. to the side reel 9, and to the bin 59.
When 75 contacts switch 60.76, motors 40,4
．． 1 stops, motor 39 also stops, and the small cassette)
It will be in the same state as when A was attached to 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.

Incidentally, during the loading operation, the coil spring 57, 73 and the stopper keep the motor 40, 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 allow the guide row to be wound up according to 58.74. Also, unloading as well! During operation, the reason why the motor 39 is operated even after the guide rollers 44 and 45 are in the position shown in FIG. 3 is to eliminate tape slack and completely wind the tape onto the take-up reel 9. This is to keep it safe.

In Figures 2 to 4 above, when the small cassette A is used in a standard type recording/recording/playback machine, it has a rechargeable power supply, and the motor is driven by this power supply, and the tape path forming mechanism is activated. We have described a tape cassette adapter that operates to form a tape path that is approximately the same as that of a standard type tape cassette, but the tape path forming mechanism manually operates the operating lever, which rotates the guide roller. The tape cassette adapter may be moved to form a predetermined tape path.

FIG. 5 is an explanatory view of the main parts of one embodiment of the tape winding adapter according to the present invention, and FIG. 6 is a diagram showing the small cassette l-A attached to the adapter B. FIG. 2 is an explanatory diagram of the relationship in which the tape is wound.

In the figure, reference numeral 0 indicates a tape winding adapter, and this adapter C has a storage portion in which the adapter B can be stored. Also, this storage section is provided with a lid (not shown).

When the small capacitor A mounting adapter B is installed in this storage part, the supply side reel disk 200 that connects with the supply reel 8 of the compact capacitor A, and the winding of the small capacitor A) are installed. Gear 98 and gear 9 meshing with teeth 16 of take-side reel 9
A winding-side reel disk 201 is provided which is inserted into and coupled to the guide hole 103 of the gear 96 meshing with the gear 97 integrally formed with the winding side reel disk 8 .

202 is a light emitting body for detecting the end of the tape when the small cassette mounting adapter with a predetermined tape path formed is stored in the storage section and the tape is wound; 204 is a photoreceptor, and the light emitter 202
When the light emitted from the tape is detected by the photoreceptors 203 and 204, this light is transmitted through the transparent portion at the end of the tape, and thus indicates the end of the tape.

Further, a hole 205 is formed in the bottom plate of this storage part, a slide cover 206 is provided in this hole 205, a protrusion 207 for a handle is formed in this slide cover 206, and further, Contact pieces 208 and 209 are attached to predetermined positions on the back surface of this slide cover 206. The contact pieces 208 and 209 are made of a conductive elastic material so that they can protrude onto the surface of the bottom plate of the storage section when the slide cover 206 is in the open state.

210 is a drive motor for the supply side reel disk 200, and 211 is a drive motor for the take-up side reel disk 201. When the plug 212 is inserted into the AO outlet and the power button 213 is pressed, the power lamp 214 lights up and the power is turned on. supplied and 1% EW button 215
When , for example, only the motor 210 is driven, and the tape 10 of the small cassette A attached to the adapter is wound in the REW direction, and when the FF button 216 is pressed, for example, only the motor 211 is driven, and the tape 10 of the small cassette A attached to the adapter is wound up in the REW direction. The tape 10 of the small cassette (A) is wound in the FF direction.

These motors 210.211 are mounted on the mounting plate 217.2.
Fixed circular bodies 221 and 222 are attached to the upper side of the motors 210 and 211 with washers 219 and 220 in between, and this fixed circular body 221
．． Felt 223 and 224 are on 222, and felt 2
Rotating circular bodies 225 and 226 are provided on the rotating circular bodies 23 and 224, and coil springs 227 and 228 are provided on the rotating circular bodies 225 and 226 to press the rotating circular bodies downward. Circular bodies 225, 226 and fixed circular body 221.
222 has a friction clutch configuration, in which the driving force from the motor 210 is transmitted to the supply reel 8 via the supply reel disk 200 while resisting friction, and the tape 10 is transferred from the take-up reel 9 to the supply side. reel 8
The driving force from the motor 211 is applied to the reel disk 201 on the winding side and the gear 9 while resisting the friction force.
6. The signal is transmitted to the take-up reel 9 via gears 97 and 98, and the tape 10 is wound from the supply reel 8 to the take-up reel 9. When the motor 210 is in operation, the motor 211 is inactive, and when the motor 211 is in operation, the motor 210 is inactive, and the tape tension on the supply reel 8 or the take-up reel 9 causes the supply side to be The reel 8 or the take-up reel 9 rotates accordingly. Also, for example, while the tape is being wound to the supply reel 8 side, the relative rotational speed balance between the supply reel 8 and the take-up reel 9 is lost, and the tape is completely unwound from the take-up reel 9 first. To prevent this, the back tension is applied to the tape by the friction force generated from the friction clutch structure.

Further, the motors 210 and 211 are configured to automatically stop when the tape being wound reaches the tape end based on the tape end detection output of the tape end detection mechanism using the light emitter 202 and the light receivers 203 and 204. .

In order to stop driving the motors 210 and 211 in the middle of the tape, instead of stopping at the end of the tape, the motor 21'0 and 211 are configured to stop when the stop button 229 is pressed. In addition, such a stop button 2
Even when the motor is stopped by pressing 29, the friction structure is still in effect, so the reel on the winding side will not rotate further due to inertia and excess tape will not be fed out.

230 is a reset button, 231 is a counter, 232 is a pulley attached to the motor shaft of the motor 211,
233 is a worm 234 meshing with the gear of the counter
Boo attached to 1. ', 235Vi' This is a belt that connects the pulleys 232 and 233, and is used to detect and display the amount of tape winding.

Further, 236 is a low power supply voltage section, and the plug 212 is connected to A.
, plug it into the O outlet, and press the power button 21
When 3 is pressed, D supplied through the low supply voltage section 236
C current causes power wrap 214 to illuminate.

Dad, this Adapter C has a charging function. For example, if the adapter for the tape cassette is the adapter B which uses a battery as its driving source as described above, if the battery power decreases, the tape loading knob will be affected.

Therefore, as shown in Fig. 7, the batch IJ of adapter B
- Slide the slide cover 121 provided on the lower side of the adapter B, and attach the contact pieces 122 and 123 to the F.
・The slide cover 20 of the adapter C is configured so that it can protrude from the cover 32 by its own elastic force.
6 is opened and the contact pieces 208 and 209 are prepared in advance so that the contact pieces 12 and 209 are protruded.
2.123 and the contact pieces 208 and 209 come into electrical contact with each other and are in a conductive state. When the charging button 237 is pressed in this state, the lamp 238 indicating that charging is in progress lights up, and the DC current converted by the low-voltage power supply unit passes through the contact pieces 208, 209, 122, and 123 to the battery 120. The battery is supplied to the battery, and charging is performed.

When charging is completed, the lamp 238 is turned off to indicate that charging is complete.

Note that this charging can be performed even during tape winding operation.

In addition, in the above adapter B, the tape feeding lever 42
．． 43, the power of the batch IJ-120 decreases and stops midway, and therefore, when the small cassette attachment adapter B is attached to such a straight adapter C, the There is a possibility that a collision may occur with the light emitting body 202 that is present.

Therefore, in consideration of this, the light emitting body 202 is designed to be movable. For example, as shown in Figure 8,
The mounting plate 239 of the light emitting body 202 is attached to the bottom plate of the storage part with a hinge, and the tip of the mounting plate 239 is held by contact pieces 240 and 241,
When the power button is pressed, the contact piece 240.241
The light emitter is in the operating state depending on the conduction state of the
When the mounting plate 239 is pressed downward, the mounting plate 239 rotates about the axis of the hinge, and the issuer 202 is moved by the contact piece 240.
241 becomes inactive and retracted from the upper surface of the bottom plate of the storage compartment, so even if the tape feed lever is in a halfway position, the small cassette mounting adapter B cannot be moved to the storage compartment of adapter C. can be completely attached to the Therefore, as long as the light emitting body 202 is retracted, there is no problem even in the above state.

Furthermore, in the above embodiment, the tape cassette adapter is of the type that has a rechargeable power source, but the tape path forming mechanism does not have a rechargeable power source that is operated manually using the operating lever. Even if it is of the same type, there is absolutely no problem with it. The tape winding adapter C of the above embodiment is a small cassette A.
As explained in the case of attachment adapter B, small cassette A attachment adapter B has essentially the same configuration as a standard type tape cassette, so it can be used as a tape winding adapter for a standard type tape cassette. will also be used.

Reference numeral 242 is a protrusion, which functions to release the reel brake of the standard type tape cassette when a standard type tape cassette is attached to the adapter C, and also serves to release the reel brake of the standard type tape cassette when the adapter C is attached to the adapter. C
Even when the adapter B is attached to the take-up reel of a small-sized tape cassette, it functions to release the brake of the indirect brake mechanism constructed in the adapter B.

As mentioned above, the tape winding adapter according to the present invention allows a tape cassette that is smaller than the standard type to be used in a standard type recording and/or playback machine. A storage section capable of storing a cassette adapter is configured, and when the tape cassette adapter to which the small tape cassette is attached is installed in the storage section, a first a reel disk, a second reel disk coupled to a gear of a tape cassette adder that meshes with a gear portion of a take-up reel of the small tape cassette, and a first and/or second reel disk. Since it is equipped with a drive mechanism that rotates in the tape winding direction, it is possible to play back information in cases where recorded information spans multiple tape cassettes due to the short tape length due to the nature of small tape cassettes. Even if you want to enjoy a tape cassette, there is no need to load the tape cassette into the recording/playback machine, wind the tape, and then go through the playback process. You can prepare the tape by winding it into the desired object.In particular, you can wind up a small tape cassette while it is attached to the tape cassette adapter, so you can attach it to the recording/playback machine as is, and it is easy to handle. becomes more convenient, allows you to prepare for playback smoothly, makes playback even more enjoyable, and
If the tape winding adapter configured as described above is further provided with a mechanism that detects the tape end when the tape winding is performed and stops the driving force of the tape winding drive mechanism, the tape winding This prevents the tape from being pulled even after the tape winding is completed, so the tape will not be damaged, and the tape winding operation can be performed without paying too much attention. Among these features, it allows the tape winding operation to be carried out with peace of mind and makes playback even more enjoyable.
