Although the 105D is used less frequently, adjustments may be necessary from time to time. For this reason, it cannot be operated in the dark, so lighting is required. In the past, since it was used infrequently, no special lighting was provided, which was inconvenient when adjustments needed to be made in a dark place.

Further, in the conventional device, the panel frame 100 is removed and the light source 111 is replaced. Therefore, it was difficult to replace the light source 111.

The first object of this invention is to provide a structure of a display device that can reduce the area of the main operation panel.

A second purpose of this invention is to provide a display device that can illuminate even operating elements that are infrequently used.

A third object of this invention is to provide a display device in which the light source can be replaced without removing the panel frame, and maintenance can therefore be easily performed.

``Means for solving the problem'' This invention has a structure that has pores along the sides of the main operation panel and illuminates the main operation panel by shining light onto the main operation panel through these pores. In a display device for a ship equipped with lighting means, a main operation panel is provided to be openable and closable with respect to a panel frame, and a sub-operation panel is provided behind the main operation panel.
The side of the main operation panel on which the illumination means is provided is a rotating free end.

In this invention, a third operation panel is further provided along the lower side of the display window, and a rotary adjustment type adjuster, which is used relatively frequently, is attached to this third operation panel.

According to the configuration of this invention, the main operation panel is illuminated by the light emitted from the pores.Furthermore, by opening the main operation panel, the sub-operation panel installed behind it is also illuminated by the light emitted from the pores. Ru.

Furthermore, according to this invention, the rotary operation type adjuster, which is frequently used, is attached to the operation panel provided along the lower side of the display window, so the rotary operation type adjuster can be removed from the main operation panel. As a result, the area of the main operation panel can be reduced, and the overall shape of the device can be made smaller.

Furthermore, according to this invention, since the main operation panel has a structure that can be opened and closed, the screws fixing the light source that illuminates the pores can be loosened by opening the main operation panel. Therefore, the light source can be replaced without removing the panel frame.
