Description

[Detailed description of the invention] The present invention relates to a tape winding adapter that winds tape in a tape cassette smaller than a standard type tape cassette. A reel disk coupled to the reel and a gear meshing with a gear portion of a take-up reel of a small tape cassette are provided, and a drive motor is provided to drive these reel disks and/or gears in the tape winding direction. For example, if you want to play back a small tape cassette at a desired location, you can do it with a simple device without having to install it in the recording/playback machine each time.
Therefore, even when information recording spans a plurality of small tape cassettes and it is desired to reproduce only a specific portion of the information recording of these plural small tape cassettes, the tape winding device allows for smooth playback. The purpose is to provide an adapter.

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 the frame of this small cassette A consists of an upper half 1, a lower half 2, and a front cover 3 for protecting the tape. It is rotatably attached to the upper part 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 cover 3 is in the closed state, the front cover 3 is maintained in that state, and when the front cover 3 is opened, the open state is maintained.

A supply reel 8 and a take-up reel 9 are arranged in the small cassette A, and the distance between the supply reel 8 and the take-up reel 9 is such that the distance between the supply reel 8 and the take-up reel 9 is a standard type that cannot be installed only in the small cassette A. The distance is shorter than the distance between the supply reel disk and the take-up reel disk of the recording/reproducing machine.
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 moved from the supply reel 8 to the guide pole 1.
1 and 12, and is then wound onto the take-up reel 9. An uneven groove is formed on the lower surface of the lower flange of the supply 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 biased toward the lower half 2 by the action of the attached leaf spring, and the uneven grooves engage with each other.
The supply reel 8 is fixed to prevent the magnetic tape wound on the supply reel 8 from loosening. still,
When the small cassette A is attached to a recording/reproducing machine or an adapter to be described later, the supply reel 8 is moved toward the half 1 side by a specified amount by the repulsive force of the leaf spring by the supply reel disk of the recording/reproducing machine or the reel disk of the adapter. It is lifted up against the resistance, and the engagement between the concavo-convex grooves is released and it becomes possible to rotate. That is, a hole 13 for inserting a supply reel disk 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. In addition, the take-up reel 9 is
It is inserted into a shaft 14 fixed to the lower half 2, and is rotatable about this shaft 14.

A brake mechanism is disposed on the take-up reel 9 so that the take-up reel 9 does not rotate when the small cassette 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 15 of the take-up reel 9. This brake is inserted into a shaft formed integrally with the lower half 2, and is operated by a spring. When it is pressed and energized, the shoe portion 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. Furthermore, when the small cassette A is attached to a recording/reproducing machine or an adapter described later, a force is applied that resists the repulsive force of the spring, the shoe part of the brake is separated from the lower flange 15 surface, and the take-up reel 9 can rotate. It becomes like this. The rotation of the take-up reel 9 is different from that of the supply reel 8,
This is accomplished 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. Therefore, a notch 17 is formed in the lower half 2 so that the driving force transmission medium can mesh with the teeth 16 when the small cassette A is attached to a recording/reproducing machine or an adapter exclusively for this small cassette.

Reference numerals 19 and 20 indicate grooves provided on the rear side of the small cassette A, and when the small cassette A is attached to the adapter described later, these grooves 19 and 20 engage with the protruding strips of the adapter, and the small cassette This is to prevent wobbling of A. Therefore, a structure may be adopted in which a groove is provided on the adapter side and a protruding strip is provided on the small cassette side.

When recording and reproducing using the small cassette A constructed as described above, if a recording/reproducing machine exclusively for this small cassette is used, it can be installed as is, or a standard type tape cassette larger than the small cassette A can be used. When using a standard type recording/playback machine that uses Let's do it.

However, since the tape length of such a small cassette is shorter than that of a standard type, when this type of small cassette A is used, it is inevitable that multiple small cassettes will be used in succession at once. There are many things. If you want to play back only the desired parts recorded on multiple small cassettes one after another, it would be too troublesome to have to attach each tape to a recording/playback machine and run the tape to find the desired part. This will reduce the enjoyment of the system by half, and furthermore, it will not be possible to respond in an emergency.

Therefore, for example, when playing the above-mentioned small cassette, it is possible to find a desired position without using a recording/reproducing machine.In other words, it is possible to move the tape of the next small cassette to the desired position while the previous small cassette is being played. We proposed a tape winding adapter that allows tape winding and smooth playback without halving the enjoyment of playback.

FIG. 2 is a perspective view of essential parts of an embodiment of the tape winding adapter according to the present invention, and FIG. 3 is an explanatory diagram when a small cassette is attached to the tape winding adapter.

In the figure, B is a tape winding adapter that has approximately the same external shape as a standard type tape cassette, and this adapter B has a storage section C that can store, for example, a small cassette A with the front lid 3 closed. It is configured.

When the small cassette A is installed in this storage part C, the grooves 19 and 20 of the small cassette A fit into this storage part C to position the small cassette and to prevent the small cassette A from being incorrectly inserted in the front and rear directions. Projections 30 and 31 are provided on the rear side wall surface thereof.

Furthermore, when the small cassette A is installed in the storage section C, the supply reel 8 of the small cassette A is slightly lifted, the brake of the supply reel 8 is released, and the driving force is transmitted to the supply reel 8. A reel disk 32 is provided, and a lower flange 15 of the small cassette A is provided.
A gear 33 that meshes with the teeth 16 is provided.

Although not shown, a protrusion is provided at a predetermined position in the storage section to release the brake on the take-up reel 9 when the small cassette A is installed in the storage section C.

34 is a drive motor for the reel disk 32, 35 is a drive motor for the gear 33, and when the plug 36 is inserted into an AC outlet and the power button 37 is pressed, the power lamp 38 lights up.
When power is supplied and the REW button 39 is pressed, for example, only the motor 34 is driven and the tape 10 of the small cassette A attached to the adapter is REWed.
If you press the FF button 40 again,
For example, only the motor 35 is driven so that the tape 10 of the small cassette A attached to the adapter is wound in the FF direction.

That is, the motors 34 and 35 are attached to the mounting plates 41 and 4.
Fixed circular bodies 45 and 46 are attached to the upper sides of the motors 34 and 35 with washers 43 and 44 in between, and these fixed circular bodies 4
Felts 47 and 48 are placed on the felts 5 and 46, rotary circular bodies 49 and 50 are placed on the felts 47 and 48, and the rotary circular bodies are pressed downward on the rotary circular bodies 49 and 50. Coil springs 51 and 52 are provided, and rotating circular bodies 49 and 50 and fixed circular body 4
5 and 46 have a friction clutch configuration, and the driving force from the motor 34 is transmitted to the supply reel 8 via the reel disk 32 while resisting the friction force, and the tape 10 is transferred to the take-up reel 9.
from the supply side reel 8, and the motor 35
The driving force from is transferred to gear 3 while resisting the friction force.
3 to the take-up reel 9, and the tape 1
0 is wound up from the supply reel 8 to the take-up reel 9. Note that when the motor 34 is in operation, the motor 35 is inactive, and when the motor 35 is in operation, the motor 34 is inactive, and the tape tension on the supply reel or take-up reel causes the supply side to be The reel or take-up reel rotates accordingly.

A reflecting plate (not shown) is provided at a predetermined position on the lower surface of the reel disk 32 and the gear 33, and a light emitting/receiving element 5 is provided corresponding to the reflecting plate.
3 and 54 are provided, the light emitted from the light emitting part of the light emitting light receiving element is reflected by the reflecting plate and received by the light receiving part, and the pulse from the light emitting light receiving element is detected, and this pulse is transmitted for a certain period of time. A tape end detection mechanism is provided which includes a control circuit that stops the winding drive when the tape ends, and the winding operation is automatically stopped when the tape to be wound reaches the final end.

A stop button 55 is used to stop the winding operation before the end of the tape is reached. Even when the take-up operation is stopped by pressing the stop button 55, the friction structure is in effect, so the take-up reel or the supply reel does not rotate further due to inertia, and the tape continues to flow. I've never had a time when my muscles loosened.

56 is a reset button, 57 is a counter, 58
is a pulley attached to the motor shaft of the motor 35; 59 is a pulley attached to a worm 60 meshing with the gear of the counter; 61 is a belt connecting the pulleys 58 and 59; It detects and displays.

Note that 62 is an AC/DC converter, and 63 is a lid.
