れている場合もある。[Prior Art] Conventionally, there is an optical disc having an air sandwich structure as shown in FIG. This optical disc 31 is assembled by bonding two transparent substrates 31a, 31b made of acrylic or the like to an outer spacer 31d and an inner spacer 31e arranged concentrically with each other via an adhesive 31c. At this time, when using a photo-curable adhesive as the adhesive, a high pressure mercury lamp 39 is provided above the turntable 24,
Adhesion is performed by irradiating light for a predetermined time. in this case,
A quartz glass plate 36 and a metal ring 38 having a thickness of about 5 mm are placed as a weight, the information recording parts 35 and 37 are positioned inside each other, and each information recording part 35 or 37 and a spacer are placed.
It is assembled so that 31d and 31e do not overlap. In addition, the information recording units 35 and 37 may be provided on only one surface.

題もあった。In addition, although a rod-shaped lamp is provided in the light source in the light irradiation device and a mirror box with a slit is used,
The rod-shaped lamp has problems that it is difficult to remove heat rays, and that light from a light source is directly irradiated through a slit to a portion such as an information recording portion that does not need to be irradiated with light.

The weight consisting of is raised by the weight support 4.
In that case, the corner on the outer side of the bottom of the metal ring 38 is chamfered so that the metal ring 38 smoothly fits into the weight-positioning projection 5 and is supported by the weight-supporting body 4 at a predetermined position to rise. Incidentally, as a reminder, similarly to the case of ascending, the case 5 is mounted on the optical disk 31 on the turntable 24 by the descending of the weight support 4 while being fitted to the protrusion 5 and at the predetermined position. Therefore, the central fitting hole of the quartz glass plate 36 is fitted smoothly to the rotary shaft 24a of the turntable, and the metal ring is fitted smoothly to the side surface 24b of the turntable.

Stops when it further rises to a position that does not hinder the movement of the turntable 24 for entering and exiting. After that, the ball screw 12 is rotated by the rotation of the motor 13, which causes the turntable 24 to move on the rail 11 on the turntable moving table 10.
The optical disc 31 that has moved along with it and has been optically bonded is removed from the turntable 24. Thereafter, the same steps are repeated to perform the photo-adhesion process.

Is attached to the spacer ring while being held and fixed to the spacer ring in the casing.
