In an optical disk as an information storage medium used in this optical disk device, frequency-modulated information signals are stored in an information storage layer in the form of rectangular small holes (bits).

The optical disk device is equipped with a mechanical unit that rotates such an optical disk, irradiates the information storage layer with a laser beam as a focal point, and stores and reproduces stored information using the reflected or transmitted light. There is. Further, the optical disk device is equipped with an electric circuit board that is a signal processing member that converts information stored and reproduced by the mechanical unit into electric signals.

Furthermore, an opening is formed in the front of the main body of the apparatus, into which an optical disc can be inserted and taken out.

Optical disk devices are usually mounted on racks.

The rack is configured to cover the main body of the optical disk device from above and below, as well as from the left and right sides. Therefore, the front and back surfaces of the optical disk device mounted on the rack are exposed to the outside, where the openings are formed.

Incidentally, optical disk devices require high accuracy when converting information on an optical disk into electrical signals.

Therefore, it is necessary to adjust the electric circuit board not only during manufacturing of the optical disk device but also during maintenance.

However, in conventional optical disk devices, in order to adjust the electrical circuit board, it is necessary to remove the top cover of the device body, remove the side wall, and pull out the board to the side, which is a cumbersome process. .

Furthermore, since the optical disk device is mounted on a rack, the device must be removed from the rack in order to remove the top cover and side walls of the device body, making adjustment of the electrical circuit board even more complicated.

(Problems to be Solved by the Invention) As described above, in the conventional information processing device, when the signal processing member is adjusted while the device is mounted on the rack, it is necessary to adjust the signal processing member after the device is removed from the rack. , which required complicated work such as disassembling the main body of the device.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide an information processing device whose signal processing members can be easily adjusted even when mounted on a rack.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention includes a mechanism section for storing and reproducing information on an information storage medium, and a mechanism section for storing and reproducing information on an information storage medium, and a mechanism section for storing and reproducing information by the operation of this mechanism section. a signal processing member for converting information into electrical signals; a device main body in which the mechanical section and the signal processing member are housed; and an opening formed in the front of the device main body into which the information storage medium can be inserted and removed. , and an adjustment port is provided on the front or back side of the apparatus main body so that the signal processing member can be adjusted from the τ side with respect to the mechanism section.

(Function) In the above configuration, adjustment of the signal processing member during manufacturing of the information processing device can be performed from the side with respect to the mechanism section through the adjustment port. Moreover, since the adjustment port is formed on the front or back of the device body, the signal processing member can be adjusted through the adjustment port even when the information processing device is mounted on a rack during maintenance or the like.
