いる。DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an assembly diagram of essential parts showing an embodiment of the present invention. In FIG. 1, 11 is an LCD frame,
11a is an LCD frame leg, 11b is an LCD frame claw, 12 is a circuit board, and 12a is a notch provided in the circuit board. Although not shown in the figure, a rubber connector is inserted between the LCD frame 11 and the circuit board 12, as in the conventional case, to electrically connect the LCD and the circuit board.

構造である。[0009] Regarding the actual shape of the LCD frame 11, it is preferable that the LCD frame 11 be box-shaped so that the mounting position of the LCD does not shift. A structure in which a rubber connector is used to connect the LCD and the circuit board, the LCD frame legs 11a are fitted into the notches 12a, and the LCD frame 11 is mounted on the circuit board 12 using the reaction force of the rubber connector. It is.

ので、爪部１１ｂのねじ曲げも不要である。Here, the portion through which the LCD frame leg portion 11a passes is not provided in the circuit board as shown in FIG. 5 in the conventional method.
By forming the notch 12a, the size thereof is the same as that of the LCD frame leg portion 11a, so that the LCD frame 11 can be mounted on the circuit board 12 with a smaller area than the conventional mounting area. Further, since the structure is such that the claw portion 11b is hooked using the end face of the circuit board 12a as a guide, there is no need to twist the claw portion 11b.
【００１１】図２は、他の実施例における切り欠き部１

持力が得られる。Reference numeral 12b denotes a groove provided in the notch 12a, into which the LCD frame claw 11b is fitted. Therefore, when an external force is applied to the LCD frame 11, it becomes difficult to come off from the circuit board 12, and sufficient maintaining force can be obtained without twisting the claw portions 11b inward to the circuit board.

This structure increases the contact pressure between the frame claw portion 11b and the electrical grounding contact surface. That is, the protrusion 1
This is because 1c reduces the contact area and increases the contact pressure per unit area. Therefore, reliable grounding is possible due to the contact pressure.

The structure is such that the LCD frame 41 is mounted on the circuit board 42 by fitting the claw portion 41a into the notch 42a. In this case as well, although not shown in the figure as in the case of FIG. 1, a rubber connector is inserted between the LCD frame 41 and the circuit board 42 as in the conventional case, and electrical connection between the LCD and the circuit board is made. .
