PROBLEM TO BE SOLVED: To provide facilitate mounting/dismounting of a display unit to a frame. SOLUTION: When knurling 10 is rotated in one direction, a screw 14 rotates. The screw 14 is freely rotatably held to a front frame 1 by a press plate 22 and a screw 21 and therefore when the screw 14 rotates, the internal thread plate 23 to which the screw 14 is screwed parts from the screw 14. Parting of the internal thread plate 23 from the screw 14 eventually leads to the removability, as an integral unit, of a supporting member 15 integrated with the internal thread plate 23, a cap 8, a lateral guide shaft 7, a longitudinal guide plate 9, a longitudinal position regulating recess 13 fitted to the longitudinal guide plate 9, a vertical guide cover 4 partly constituted by the longitudinal position regulating recess 13 and a display unit mounted at the vertical guide cover 4.
