In this state, when the drive roller sucked by the belt suction mechanism is moved in the circumferential direction (horizontal direction), the circumferential surface of the drive roller comes into contact with the inner surface of the drive belt, and the drive belt is moved to the first and the first positions. It is in a state of being suspended by the second belt temporary suspension member and the drive roller.

As described above, the drive roller and the drive belt suspended on the first and second belt temporary suspension members are pulled out from the tray, and the third and fourth belt temporary suspension members are moved toward the drive belt. Then, the peripheral surfaces of these third and fourth belt temporary suspension members come into contact with the outer periphery of the drive belt, press the drive belt, and have a substantially T-shaped drive belt similar to the drive belt path system of the data cartridge.

Contact and release of contact can be performed smoothly.

In addition, since the pair of the belt temporary suspension members such as the first and second belt temporary suspension members or the third and fourth belt temporary suspension members are rotated in the same direction, the paired temporary suspension members are rotated. When, for example, the temporary belt suspension member makes contact with the drive belt, the wear resistance between the pair of temporary belt suspension member and the drive belt acts as a force to rotate the drive belt in the same direction, and the pair of belts. When the temporary suspension member comes into contact with the drive belt, it is possible to prevent the drive belt from expanding or contracting between these paired belt temporary suspension members.

.. 61 are arranged in an arc shape, so that the abrasion resistance with the drive belt 6 is reduced, and the third and fourth belt temporary suspension members 10, 11 and the drive belt 6 can be smoothly contacted and separated. In the embodiment, only the third and fourth belt temporary suspension members 10 and 11 are constituted by a large number of rotating rollers 61. This is because the third and fourth belt temporary suspension members 10 and 11 are larger than the first and second belt temporary suspension members 8 and 9 (the tape supply hub 16 and the second belt temporary suspension members 14 and 15 are larger than the first and second corner rollers 14 and 15). The diameter of the tape winding hub 17 is extremely large,
Since the third and fourth belt temporary suspension members 10 and 11 are made in accordance with the diameters of these hubs 16 and 17, the frictional resistance with the drive belt 6 also increases, so that the first and second belt temporary suspension members are increased. This is because the necessity is higher than the members, but if necessary, the first and second belt temporary suspension members 8 and 9 can be used.

In FIG. 4, when the first belt temporary suspension member 8 rotates clockwise and the second belt temporary suspension member 9 rotates counterclockwise, the first and second belt temporary suspension members are rotated. The drive belt 6 is partially contracted between the members 8 and 9,
Conversely, when the first belt temporary suspension member 8 rotates counterclockwise and the second belt temporary suspension member 9 rotates clockwise, the first belt temporary suspension member 8 moves between the first and second belt temporary suspension members 8 and 9. As a result, the drive belt 6 is partially extended.

The belt assembling apparatus of the present invention has the following effects.

(1) It is not necessary to attach a so-called temporary assembling device to the belt assembling device, whereby the entire structure of the belt assembling device can be simplified and downsized.

(2) The process of assembling the drive belt and the process of attaching the corner rollers, the tape supply hub, and the tape take-up hub can be dispersed, so that the operation time can be reduced in one process section and the working efficiency can be reduced. Can be planned.

(3) Since the belt temporary suspension member is formed in an arc shape by a number of rotating rollers, abrasion resistance between the belt temporary suspension member and the drive belt is reduced, and the belt temporary suspension member is applied to the drive belt. Contact and separation can be performed smoothly.

(4) Since the pair of belt temporary suspension members is rotated in the same direction, the drive belt partially contracts or contracts when these belt temporary suspension members come into contact with the drive belt. Extension can be prevented.
