2. Description of the Related Art Conventionally, a pancake reel around which a plurality of copies of video software having the same contents are wound is mounted on a reel stand, and the copy tape is automatically transferred from the pancake reel mounted on the reel stand. A so-called video cassette loader has been proposed in which a copy tape of one video software is automatically accommodated in the video cassette by being pulled out.

In such a video cassette loader,
For example, 100 video cassettes can be made from one roll of pancake reel. The pancake reel on which all copy tapes are wound must be manually removed from the reel stand of the video cassette loader as a simple reel (generally called a hub), and a new pancake reel must be manually attached to the reel stand. Then, the work of winding a new video tape into the cassette by the video cassette loader is automatically performed.

In this case, in order to avoid the interruption of the winding operation, normally, two video cassette loaders are prepared, and while one pan of the video cassette loader is being replaced with another pancake reel. One was used to perform the operation, or tape winding operation.

However, in the conventional technique for operating two video cassette loaders in this manner, the volume occupied by the video cassette loader itself increases and the video cassette loaders operate independently of each other. There was a problem that the timing of exchanging the cake reels might be the same.

As a conventional technique for solving such a problem, there is a tape winding device disclosed in Japanese Patent Laid-Open No. 64-33783.

The magnetic tape 6 is pulled out from the magnetic tape 5, and the magnetic tape 6 pulled out to the empty cassette 7 is wound in the arrow direction.

[0008]

However, as shown in FIG.
In the conventional technique shown in (1), since the pancake reels 4 and 5 are arranged in a plane, as a result, the volume of one winding device becomes relatively large, and the operation of the device is not easy. There is a problem. In addition, in order to further increase the number of pancake reels, the volume of the device itself increases, and it is necessary to consider the strength of the device again. There was a problem that it would increase significantly.

The present invention has been made in view of the above problems, and it is an object of the present invention to provide a tape winding device capable of mounting a plurality of pancake reels and having a relatively small shape. To aim.
