It is rotatably installed, and this drive shaft 5 is equipped with a drive device as defined in the present invention. The power of the electric motor 6 is transmitted through the chain and sprocket. A drive sprocket 12 is provided on the drive shaft 5 corresponding to each of the pillars 4. is set up. Note that this electric motor 6 has a speed reducer and can be operated in forward and reverse directions by a commercial power source. It can be rotated.

[0018] The support column 4 is formed by using a channel material that opens outward as shown in FIG. In the grooves 4a of the channel material of these supports 4, a chain as a wrapping medium is placed. The chain 7 is attached to the column 4, and the support 4 is a frame for attaching the chain 7. The portion 4a functions as a guide groove for the chain 7.

[0019] This chain 7 is installed at a lower position than the bed 1 on both sides of the bed 1. After winding the placed idle sprocket 8, it is guided to the center side of the pit 2, The drive sprocket installed on the drive shaft 5 passes through the second idle sprocket 11. It is wound around the jacket 12 to form a ring shape.

[0020] Therefore, each chain 7 installed on each pillar 4 is connected to the electric motor 6. It is possible to drive forward and backward at the same speed depending on the output.

[0021] The following light-shielding sheets 13 are attached to each of the pillars 4 configured in this way. There is.

[0022] The light-shielding sheet 13 is spaced approximately 50 cm apart from a completely light-shielding sheet material 14 with high reflectivity. Seven straight pipes 15 made of steel pipes attached to a sheet material 14 (in the invention of this application, the bar material) corresponding), and further connected to and held at both ends of this steel pipe 15. It has a light shielding sheet 16.

[0023] The lengths of the sheet material 14 and the steel pipe 15 of this light shielding sheet 13 are set at both sides of the bed 1. It is approximately 30 cm longer than the spacing between the pillars 4 installed at the ends. When the light-shielding sheet 13 is attached to the pillar 4, the ends of this light-shielding sheet 13 are attached to both sides. As shown in Figure 2, the second light-shielding sheet protrudes outward from the support 4. Each of the holes 16 is positioned to cover the outside of the support column 4 at the end.

[0024] In such a light shielding sheet 13, the light shielding sheet 13 is arranged at the front end of the chain 7 in the closing direction. straight pipe (hereinafter referred to as tip straight pipe 15a to distinguish this straight pipe from other straight pipes) is connected to the chain 7 via a string 17 as shown in FIG. 2, but other The straight pipe 15 is not connected to the chain 7.

[0025] Note that when connecting this straight pipe 15a to the chain 7, the straight pipe 15a is 5a is attached to each chain 7 of each support 4 so that it is horizontal. There is.

[0026] Therefore, as the electric motor 6 is driven, the light shielding sheet 13 is While maintaining the horizontal position, the pipe 15 moves along the outer periphery of the support column 4 in the area indicated by the arrow in FIG. It can be moved up and down within the range. Note that G in each figure indicates the ground.

[0027] In the short day processing apparatus S of this embodiment, the operation of the light shielding sheet 13 is as follows. It's good.
