Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an adapter used in conjunction with a tape winder for fast winding or rewinding of tape in a tape cartridge.

This type of tape winder is equipped with a take-up shaft and a supply shaft, and the distance between the shafts is preset to a certain dimension to correspond to the distance between the hub shafts of certain tape cartridges. There is. In other words, conventional tape winders are limited in the number of tape cartridges that can be used. Therefore, among tape winders, for example, those designed for audio Phillips-type tape cartridges have the disadvantage of not being able to quickly wind ultra-small tape cartridges smaller than that size, so-called micro cassettes. It was hot.

This invention focuses on this fact, and by using an adapter in conjunction with the present invention, it is possible to quickly wind or rewind tapes from various tape cartridges of different sizes using a single tape winder.

Below, the details will be explained based on the drawings. The tape winder 1 shown in the figure is for fast winding a Phillips type tape cartridge T, and this is a winder with claws a driven by a built-in motor. A take-up shaft 3 and a supply shaft 4 with a claw a to which back tension (pulling force in the direction opposite to the tape advancement) are provided upright on the tape cartridge mounting surface 1a, and the take-up shaft 3 The distance between the shafts and the supply shaft 4 matches the distance between the hubs of the Phillips type tape cartridge T.

The present adapter 2 has shaft insertion holes 7, 7 in the bottom wall 6 of the main case 5, which is formed by joining upper and lower cases 5a, 5b together in a lid-to-bottom manner. Transparent. Inside the main body case 5, main hubs 8, 8 are positioned above the shaft insertion holes 7, 7 and are rotatably installed, and sub-hubs 9 are arranged side by side between the main hubs 8, 8, and the sub-hubs 9 are disposed side by side. Peripheral gear 1 of flange 12 formed overhanging on the peripheral surface
3 is meshed with a gear 11 formed on the circumferential surface of the flange 10 of one main hub 8, and the upper end surface of one main hub 8 and the upper end surface of the sub hub 9 that meshes with the other main hub 8, Engagement elements 14, 14 each with a claw a
These engaging members 14, 14 project upward from holes 16, 16 opened in the upper wall 15 of the upper case 5a. Both engagers 1
The distance between 4 and 14 is shorter than the distance between the winding shaft 3 and the supply shaft 4 on the tape winder side, and is set to match the distance between the hub shafts of the audio microcassette t.

In such a case, remove the winding shaft 3 of the tape winder 1.
When rapidly winding a Phillips-type tape cartridge T having a hub-to-center distance that matches the distance between the hub and the supply shaft 4, place the tape cartridge T on the mounting surface 1a of the tape winder 1 as before. Then, one shaft insertion hole 18 of the tape cartridge T is inserted into the take-up shaft 3, and the other shaft insertion hole 18 is inserted into the supply shaft 4. When the winding shaft 3 is driven, the tape in the tape cartridge T is unwound from the hub above the shaft insertion hole 18 into which the supply shaft 4 is inserted, and is drawn out from the hub above the shaft insertion hole 1 into which the winding shaft 3 is inserted.
It is wound up on the hub above 8.

When rapidly winding a tape cartridge t smaller in size than the tape cartridge T, the adapter 2 of the present invention is used. In this case, as shown in FIG. 3, the shaft insertion holes 7, 7 of the adapter 2 are inserted into the winding shaft 3 and the supply shaft 4, and the adapter 2 is placed on the cartridge mounting surface 1a of the tape winder 1. Then, the shaft insertion holes 17, 17 of the tape cartridge t are inserted into the engaging members 14, 14, and the cartridge t is placed on the adapter 2. When the winding shaft 3 is then driven, the engaging element 14 rotates via the main hub 8 on the shaft insertion hole 7 into which the winding shaft 3 is inserted, and the tape in the cartridge t is inserted into the engaging element 14. It is wound around the hub above the shaft insertion hole 17. At this time, since the sub-hub 9, which is integrated with the engaging element 14 on the side that feeds out the tape, is in a transmission state with the supply shaft 4 via the main hub 8 which is in gear meshing with the sub-hub 9, the above-mentioned tape cartridge As in the case of fast winding, the tape is wound with back tension, so there is no slack in the tape.

In addition, when using the adapter 2, it is also possible to use the adapter 2 by inserting the main hub 8 on the side that is in a transmission state with the sub-hub 9 into the winding shaft 3 of the tape winder 1, contrary to the above usage method. However, in order to reduce the drive transmission loss as much as possible, it is possible to insert and connect the main hub 8, which is in a non-transmission relationship with the sub hub 9, to the drive shaft 3 as in the above embodiment. preferable.

Furthermore, the engaging members 14, 14 of the adapter 2 are connected to the fourth
As shown in the figures and FIG.
It may be possible to sink into the opening holes 16, 16 of No. 5. In this case, the engagers 14, 14 are molded separately from the main hub 8 and the sub-hub 9, respectively. Each engaging element 14 has a flange 20 integrally molded at its lower end, and a protruding piece 20a and a recess 20 at the periphery of the flange 20.
b are formed alternately in the circumferential direction. The engaging element 14 engages and disengages the protrusion 20a and the recess 20b of the flange 20 into the axial groove 21 formed on the inner periphery of the main hub 8 and the pawl a of the winding shaft 3 with respect to the main hub 8. By fitting the main hub 8 into the main hub 8 in alignment with the free claws a, the main hub 8 is mounted in a non-rotating manner and movable in the axial direction. Therefore, this engaging element 1
4 can be sunk into the main hub 8 when not in use, and is projected above the main hub 8 by the winding shaft 3 of the tape winder inserted from below the main hub 8 when in use. Also, the engager 1 is connected to the sub-hub 9.
4 has a flange 20 fitted around the inner periphery of the sub-hub 9 in a non-rotating manner and movable in the axial direction, as in the case of the engager 14 of the main hub 8 described above.
The difference is that a spring 22 is interposed between the flange 20 and the bottom wall 6 so that the force of the spring 22 causes the engager 14 to always protrude above the sub-hub 9. When the engaging element 14 is stored in a storage case or the like when not in use, it is pushed into the sub-hub 9 against the spring 22 under the pressure of the inner wall of the case.

Further, the main hub 8 and the sub-hub 9 may be driven by belt transmission instead of gear transmission. In addition, the distance between the engaging elements 14, 14 of the adapter 2 is made larger than the distance between the axes of the tape winder 1, and the tape cartridge has a distance between the hub axes larger than that of the tape cartridge to which the tape winder 1 is originally intended. It may also be possible to hang it on the tape winder 1 using the adapter 2 of the present invention.

The supply shaft 4 of the tape winder 1 may have a simple structure without a back tension applying mechanism.

Of course, the winding shaft 3 and the supply shaft 4 on the tape winder side are relative, and are used only for rewinding the tape in the tape cartridge (T or T) (in the figure, the supply shaft 4 is used as the winding shaft). Needless to say, it may also be something that is served as a gift.

Furthermore, the present invention can naturally be applied to video tape cartridges.

As explained above, this invention provides an adapter 2 that can be inserted into and removed from the winding shaft 3 and the supply shaft 4 of the tape winder 1, and connects the adapter 2 to the winding shaft 3 and the supply shaft 4, respectively. A pair of engaging elements 14, 14 are provided so that the distance between the winding shaft 3 and the supply shaft 4 is different from each other, and this engaging element 14,
14, the shaft insertion hole of the tape cartridge can be freely inserted and removed. Therefore, the tape winder may not be able to quickly wind or rewind tape cartridges that are smaller or larger than the size of the tape cartridge originally intended for use.
This is convenient because it can be easily done by simply replacing the adapter 2.
