Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape winding device and a winding method for holding a tape on a spool, and a tape cassette loaded with the tape wound by the winding device.

[0002]

2. Description of the Related Art A magnetic tape to be loaded in a tape cassette is wound and held on a spool (reel hub). This magnetic tape is wound around a spool (reel hub) having a width almost the same as the tape width for a predetermined length. To wind the magnetic tape around this spool (reel hub), the original tape is cut into a predetermined width. The magnetic tape is cut into a predetermined length in the tape longitudinal direction, and the tape cutting end is held by a spool (reel hub) and wound. This work is difficult to perform manually because the magnetic tape is narrow and the spool (reel hub) has a small diameter. For this reason, this work is almost mechanical.

[0003]

A conventional tape winding device for winding a magnetic tape around a spool (reel hub) is designed on the assumption that the cut end of the magnetic tape is straight. When the portion is straight, this end can be arranged along the peripheral surface of the spool (reel hub), and can be clamped and fixed by a clamp.

However, when the thickness of the magnetic tape is thin and the width of the tape is narrow, various stresses are applied to the tape when the tape is cut or when a magnetic layer is formed on the film and a raw material is manufactured, and as a result, in the longitudinal direction of the tape. When the tape is cut, the ends are not straight, but curled.

When the curling cut end of such a magnetic tape is fixed to the spool (reel hub), the conventional tape winding device accurately corresponds to the clamping position where the spool (reel hub) is clamped by the clamp. Therefore, in the case of a magnetic tape having a curling cut end, the non-defective product rate due to the clamp for the spool (reel hub) is 30% or less, and there is a problem that the yield is deteriorated.

The present invention has been made in view of the above point, and even if the cut end of the magnetic tape has a curling shape, the tape can be reliably fixed to the spool (reel hub) by clamping. An object of the present invention is to provide an apparatus, a winding method, and a tape cassette in which a tape wound by the winding apparatus is loaded.

[0007]

In order to achieve the above object, a tape winding device according to the present invention comprises a regulating means for regulating a tape with respect to a spool, and a cutting means for cutting the regulated tape. A tape guide means for guiding the cut end of the cut tape to the spool side, a tape holding means provided on the tape guide means for allowing the tape to follow the spool, and a clamp for sandwiching the tape end portion with respect to the spool. And a fitting means for fitting.

Further, according to the present invention, the tape is regulated to the spool by the regulating means, the regulated tape is cut by the cutting means, and the cut end portion of the cut tape is guided to the spool side by the tape guiding means. Then, the tape holding means provided in the tape guiding means is arranged along the spool, and the tape end portion is wound by fitting the clamp to the spool by the fitting means and sandwiching the clamp.

Further, according to the present invention, a regulating means for regulating the tape with respect to the spool, a cutting means for cutting the regulated tape, and a tape guiding means for guiding the cutting end of the cut tape to the spool side, A tape is wound by a tape winding device having tape holding means provided on the tape guiding means for moving the tape along the spool and fitting means for fitting the clamp for holding the tape end portion to the spool. The tape cassette is configured by loading.

[0010]

The magnetic tape is cut in a state where the position of the magnetic tape is regulated with respect to the spool, and the cut end is guided to the spool side by the guide means, and the tape holding means presses the spool peripheral surface with the guiding operation. Even if the tape end portion is attached to the curling shape, it is extended straight and is securely inserted into the clamp side, and the clamp is fitted by the fitting means so that the tape is clamped and the magnetic tape is securely attached to the spool. It is fixedly held and wound in a normal state.

In this way, the tape cassette in which the magnetic tape wound on the spool in the normal state is loaded is always recorded / reproduced in the normal state, and the reliability is improved.
