PURPOSE:To integrally associate a debugging unit without loss of external appearance of a front panel by forming the panel openably in a door shape, and mounting debugging segments and ten keys on the rear surface of the panel. CONSTITUTION:A front panel 2 is openably provided in a door shape by a hinge 3 at a body 1. A clamping screw 7 is provided at the opposite side of the hinge 3 of the panel 2. Debugging segments and ten keys 5 are provided in a space on the rear surface of a printed board 4 provided on the rear side of the panel 2. The panel 2 is normally closed, and the segments, the ten keys 5 are not exposed outside a relay device. If a debugging operation is required, the screw 7 is removed, the panel 2 is opened in the door shape with the hinge 3 as an axis as indicated by a chain line, and hence they are present. Accordingly, the segment is operated by the ten keys to collect internal information and to debug it. |
