However, the above-mentioned conventional processing box has the following problems with respect to its installation position and alignment processing. That is, (1) the optical fiber has to have a large bending radius in view of the strength of the optical fiber as compared with a general cable, and it is necessary to secure a wide space around the processing box in the control panel. It becomes difficult to secure a space for arranging other supplies.

(2) Since the distance from the optical cable is fixed (supported) in the processing box to the optical connector portion of the connection destination, the number of optical cable support points between the processing box and the optical connector increases.

(3) Since the distance from the fixed position in the processing box to the optical connector portion of the connection destination is long, there is a portion that intersects with other wiring in the control panel. In addition, the examination of the laying route and the wiring work to prevent the intersections become complicated.

The present invention has been made to solve the above problems, and the purpose thereof is to facilitate the work of connecting an optical cable to a connector located in front of a printed wiring board, and also to secure a route of the optical cable and other internal parts. It is to provide an efficient control panel that secures a space for arranging items.

It is characterized in that the work can be performed from the front surface of the chassis and the inside of the control panel.

According to a fourth aspect of the present invention, in the control panel according to the first aspect, the second aspect or the third aspect, a support for the optical cable is provided on a front surface of a printed wiring board having a connector for connecting the optical cable. The feature is that a decorative plate having a function and an appearance function is attached.

[0011]

In the control panel of the present invention, the optical cable processing device has a part which is a dead space in the control panel in the past.
In addition, the space inside the chassis is effectively used when a surplus space is generated due to the number of printed wiring boards, and it can be easily installed.
