Description

Description: TECHNICAL FIELD The present invention relates to a magnetic tape winding device that connects a magnetic tape to a leader tape and winds the tape around a cassette.

[Conventional technology]

2. Description of the Related Art Conventionally, as a magnetic recording medium for recording various data such as sound and image, a cassette tape in which a magnetic tape is housed in a cassette has been widely used. In the manufacture of the cassette tape, an apparatus is used which prepares a cassette provided with a leader tape on a take-up shaft, and connects the leader tape with a magnetic tape to wind it.

The operation of such a winding device is such that the leader tape wound around the two winding shafts of the cassette held by the holding portion is pulled out and cut by a dedicated cutter, and then the cut leader tape is cut. A magnetic tape is connected to one side, the magnetic tape is wound around a winding shaft of a cassette of a predetermined length, and finally, the wound magnetic tape is cut by a special cutter and connected to the other of the above-described leader tapes. is there.

[Problems to be solved by the invention]

The connection between the leader tape and the magnetic tape is made by abutting the end of the leader tape and the end of the magnetic tape, and affixing a pricing tape to the tape back side of the abutting portion. And
Usually, the magnetic tape is often wound with its magnetic surface facing the outside of the cassette, and therefore, the splicing tape must be attached to the back of the magnetic surface, that is, the cassette case.

Therefore, in the above conventional example, many mechanisms such as a cassette holding mechanism, a splicing tape sticking mechanism, a splicing tape supply mechanism, and a tape holding mechanism must be three-dimensionally configured and arranged on the back side of the cassette. However, for this reason, there has been a problem that the configuration is complicated, maintenance is difficult, and it is difficult to take countermeasures at the time of trouble such as abnormal feeding of the splicing tape.

Further, in the above-mentioned conventional example, the mechanism must be three-dimensionally configured and arranged on the back side of the cassette, so that when attaching the splicing tape to the magnetic tape and the leader tape, the cassette is tilted or the tape is It is necessary to slide it to a sticking position far from the cassette. However, since the length of the leader tape is determined by the type of the cassette, in a device that winds a magnetic tape on a cassette of a short type of leader tape, many mechanisms must be arranged within a narrow range. There is a problem that such a configuration and arrangement is very difficult in terms of manufacturing.

Therefore, the present invention has been made in order to solve the above-mentioned problems of the prior art, and the object thereof is that the maintenance is easy, the configuration and the arrangement are simple, and a cassette having a short leader tape can be used. An object of the present invention is to provide a magnetic tape winding device that can be applied.

[Means for solving the problem]

The magnetic tape winding device according to the present invention holds a cassette provided with a leader tape on a winding shaft at a predetermined position, and attaches a splicing tape to the leader tape and the magnetic tape of the held cassette. In a magnetic tape winding device that connects and winds a magnetic tape, a first holding mechanism that is provided at a first position near the cassette and holds the leader tape, and on a same plane as the first position. A second holding mechanism that is provided at a certain second position and holds the magnetic tape, while holding the leader tape or the magnetic tape, at a position close to the first position and at the second position. A third holding mechanism that is switched to any one of a close position and a position that is switched together with the third holding mechanism so that the third holding mechanism is close to the first position; A tape cutter that cuts the magnetic tape when the third holding mechanism is at a position close to the second position, and a tape cutter that cuts the magnetic tape when the third holding mechanism is at a position close to the second position. And a sticking mechanism for sticking a splicing tape to a leader tape or a magnetic tape held by the third holding mechanism when it is at a position close to the second position.

(Operation)

In the present invention, the third holding mechanism is configured to be switchable to any one of a position close to the first holding mechanism and a position close to the second holding mechanism, and the third holding mechanism is the third holding mechanism. When at a position close to the second holding mechanism,
An attaching mechanism for attaching a splicing tape to a leader tape or a magnetic tape is provided. Therefore, when the third holding mechanism is located at a position close to the first holding mechanism near the cassette, there is no need to attach a splicing tape, and the configuration and arrangement are simplified, and many mechanisms are arranged on the same plane. Can be placed.
