By tying the second cords 6 and 7 together, the band 2 can be reciprocally attached along the longitudinal direction of the top plate 1.

Next, the operation of the subject fixed band moving device configured as described above will be described.

The subject M is laid down with the tabletop 1 in a horizontal position, and the band 2 is moved in the longitudinal direction of the tabletop 1, that is, the body axis direction of the subject M. At this time, the first and second slide pieces 8 and 9 which are integrated with the band 2 have pulleys 4a, 4b, 4c, 4d and 5 respectively.
It moves in the same direction in conjunction with the first and second cords 6, 7 that move by the action of a, 5b, 5c, 5d. Therefore,
The band 2 can be easily and quickly moved to a desired site of the subject M.

In addition, the band 2 is supported by the first and second cords 6 and 7 which are kept at an appropriate tension on the back surface 1a of the top plate 1 and comes into contact with or close to the back surface 1a. Even if 1 is in a horizontal position, the central portion of the band 2 on the back surface 1a does not hang downward, and therefore, even if an accessory is present near the back surface 1a of the top plate 1, the band 2 contacts this. There is no such thing.

Furthermore, even when an appropriate tension is applied to the first and second cords 6 and 7, this tension is absorbed by the first and second slide pieces 8 and 9, so that this tension is applied in the lateral direction of the band 2. No tension is directly applied, and therefore the band 2 itself does not extend in the lateral direction.

After moving the band 2 to a desired region of the subject M in this manner, the band 2 is wound around the subject M and the sticking portions at both ends thereof are superposed and stuck together, whereby the subject M is It can be fixed to the top plate 1.

When a plurality of bands 2 are provided, each band may be moved and the both ends adhered by the same operation as the above-mentioned case.

2 (a) and 2 (b) show another example of a state where the band and the slide piece are fixed to each other on the back surface 1a of the top plate 1. As shown in FIG. 2 (a), the three pieces of band 2a, 2b are provided. , 2c,

By fixing the one belt 2a alone,
The two pieces of bands 2b and 2c may be interlocked and moved in the longitudinal direction of the top plate 1, respectively.

3 (a), (b), and (c) show other examples of band moving means on the back surface 1a of the top plate 1, respectively.
By arranging the pulleys as shown in FIG. 3 (a), the first and second cord bodies 6 and 7 are crossed in an X shape, or as shown in FIG. 3 (b), there are four pulleys. Even if the first and second cord bodies 6 and 7 are crossed in the X-shape at the central portion of the top plate 1 by arranging 4a, 4b, 5a and 5b, the first and second cords, respectively. The two outer lines of the bodies 6 and 7 move in the same direction, and the same action and effect as those of the embodiment shown in FIG. 1 are achieved.

Further, as shown in FIG. 3 (c), six pulleys 14a, 14b, 14c, 15a, 15b, are formed on the back surface 1a of the top plate 1.
15c is disposed, and the first cord body 16 stretched by the pulleys 14a, 14b, 14c and the second cord body 17 stretched by the pulleys 15a, 15b, 15c do not cross each other. Even if connected through the slide pieces 8 and 9 of
Since the first and second slide pieces 8 and 9 move in the same direction, the same operational effect as in the case of the embodiment shown in FIG. 1 can be obtained.

In the above description, the tension adjusting means of the first cords 6 and 16 and the second cords 7 and 17 is not referred to.
Considering that each string expands and contracts due to external conditions such as humidity and temperature, an elastic member such as a spring is interposed in a part of each string to maintain tension and absorb expansion and contraction. In the embodiment of the present invention, it is preferable to add a mechanism for pressing a part of the above to the outer side or the inner side of the top plate and a mechanism for absorbing the slack of the string body by using the ratchet.

The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the gist thereof.

For example, if the band is made of a member that does not expand and contract in the above-described embodiment, it is not always necessary to use the slide piece, and in this case, the band can be directly fixed to the cord body.
