( 4 ) A lead wire pressing member 62 is provided at the front end of the groove 60 above the connector .

[0005]

The unit guide 40 is provided on the base plate 26 with the engaging claws 4.
2 fixed. The front surface of the unit guide 40 is fitted into the opening 46 of the device panel 20, and the engaging claw 50 on the lower surface of the front surface of the unit guide 40 is engaged with the device panel 20.
Is fixed by being fitted into the engagement opening 48. Next, the playing device unit 22 is inserted through the opening 46 of the device panel 20 and fixed with the screws 56. Performance equipment unit 22
Collar but when inserted into the rear slide unit guide 40 above, which is provided on both outer side surfaces of the playing equipment unit 22
A part 66 is formed integrally with the upper part of the unit guide 40.
The pressing piece 64 is pressed and fixed, and the lead wire 2
8 is located below the front end of the groove 60.
Therefore , the lead wire 28 having the required shortest length fits into the lead wire accommodating groove 60 of the unit guide 40, thereby preventing the lead wire from being caught by the playing device unit 22 and the unit guide 40. Is done. Further, since the lead wire holding member 62 is provided, the performance device unit 2 is provided.
When the connector 2 is removed, no excessive force is applied to the connector on the board 26. When the unit guide 40 is formed of a synthetic resin, the frictional resistance is small, and the insertion and extraction of the performance device unit 22 can be performed smoothly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below in detail with reference to the drawings. However, the materials, shapes, relative arrangements, and the like of the constituent members described in this embodiment are not intended to limit the scope of the present invention only to them, unless otherwise specified. This is just an example. FIG. 1 shows an embodiment of the structure of the present invention. In FIG. 1, reference numeral 20 denotes an equipment panel, 22 denotes a performance equipment unit such as a cassette unit, 26 denotes a board, and 40 denotes a unit guide made of synthetic resin. The unit guide 40 is provided on the control board 26 with an engaging claw 42 (FIGS. 4 and 5).
(See FIG. 2) into the engaging hole 44 of the substrate 26. The components of the control circuit of the performance device unit 22 are mounted on the board 26. As shown in FIG. 2, the device panel 20 is provided with an opening 46 and an engagement opening 48. At the same time as the front part of the unit guide 40 is fitted into the opening 46 of the equipment panel 20,
