  The cover 9 has an opening 16 on the outer edge for wiring the LCD harness 10 connected to the printed wiring board built in the main body 2 to the printed wiring board built in the display unit 3.

  The aluminum sheet 17 is provided on the inner surface of the cover 9 and constitutes a ground potential. Therefore, when the surface of the LCD harness 10 is connected to the aluminum sheet 17 via a gasket or the like, high-frequency noise is shielded and stable conduction is obtained.

  The gasket 18 is bonded onto the aluminum sheet 17 and provided at a position corresponding to the rib 12. The gasket 18 corresponds to the second rib according to the present invention. Since the gasket 18 has a sponge shape inside, the LCD harness 10 can be elastically guided. Further, since the surface is conductive, it plays a role of being electrically connected to the LCD harness 10 and the aluminum sheet 17 and connected to the ground potential.

  Next, a case where the mask 8 having the LCD harness 10 fixing structure and the cover 9 are engaged will be described. A situation where the mask 8 is engaged with the main body 2 in a closed state will be described as an example. That is, the second surface 8B of the mask 8 provided with the ribs 12 and the claws 15 is exposed in the upward direction.

  First, the LCD harness 10 connected to the printed wiring board housed inside the main body 2 is wired through the opening portion 11 of the mask 8 that is rotatably provided via the main body 2 and the hinge portion 4.

  Next, the LCD harness 10 is hooked on the nail 15 according to the wiring path on the second surface 8B of the mask 8. At this stage, the LCD harness 10 exists on the upper surface 12A, but is not fixed to the guide groove 13.

  Next, the cover 9 is pressed at a position corresponding to the mask 8. At this time, the LCD harness 10 existing on the rib 12 is subjected to stress downward by the gasket 18 of the protruding cover 9. In other words, the LCD harness 10 falls into the guide groove 13 having a shape recessed at the upper surface 12A and is accommodated.

  Next, the cover 9 is engaged with the mask 8. That is, the LCD harness 10 is sandwiched between the guide groove 13 on the rib 12 and the gasket 18. The gasket 14 accommodated in the rib 12 and the gasket 18 are elastically deformed, so that the left and right directions of the LCD harness 10 are sandwiched in the left and right directions.

  The cover 9 is pressed against the upper part of the LCD harness 10 and is subjected to stress downward by a gasket 18 protruding from the cover 9. Since the gasket 18 is sponge-like inside, the gasket 18 is elastically deformed and can hold the LCD harness 10 elastically. Further, since the gasket 14 is housed in the internal space of the rib 12, the lower portion of the LCD harness 10 is also elastically held.

  Further, since the gasket 14 and the gasket 18 are conductive, they are connected to the ground potential and serve to stabilize conduction. That is, the upper portion of the LCD harness 10 is electrically connected to the aluminum sheet 17 that forms a ground potential via the gasket 18. The lower part of the LCD harness 10 is in contact with the gasket 14. Since the gasket 14 is in contact with the gasket 18, the gasket 14 is connected to the aluminum sheet 17 as a result. As described above, by sandwiching the upper and lower sides with a conductive gasket, it is connected to the ground potential and high-frequency noise is shielded.
