のとなる。In the configuration shown in FIG. 4, in order to perform good information reproduction, the light beam 1 and the disk 4, which is an information recording carrier, are required.
The position of the fence must always maintain a right angle. Therefore, the processing and assembly of optical parts such as the optical pickup main body 100 and the objective lens 2 is done at a high level! Although it is desirable to do this at the same time, such processing and assembly are complicated and therefore expensive.
このためディスク４と光学式ピックアップ本体１００と

る。To adjust the orthogonality of the light beam 17 with the disk 4 in the Y-Z plane, rotate the bolt 16 in the direction of arrow C1, so that the head 16B of the bolt 16 is in contact with the holder 14 and Since the mounting piece 101 of the main body 100 and the pin 16 are screwed together, the main body 100 rotates in the direction of the arrow D1 approaching the holder 14 using the pin 15 as a fulcrum, and as a result, the light beam 1 moves in the direction of the arrow El. On the other hand, when the bolt 16 is rotated in the direction of the arrow opposite to the above operation, the head 16 of the bolt 16 is tilted due to the elastic force of the spring.
a remains in contact with the holder 14, and the main body 100 rotates in the same direction as the arrow to move away from the holder 14 using the pin 15 as a fulcrum, and as a result, the light beam 1 also tilts in the direction of the arrow.

′しても応じきれないという問題点があった。By the above operation, the degree of orthogonality between the light beam 1 and the disk 4 in the Y-Z plane can be finely adjusted. Because of this, in order to adjust the emission direction of the light beam of the optical pickup, parts such as a halter and pins are required to hold the main body rotatably, making the overall structure complex. There was also the problem that the market demand for smaller and thinner devices could not be met.
