足１９ｂを屈曲して固定する構造としてある。FIG. 4 shows an LCD mounting structure using a conventional LCD mounting tool. As shown in FIG. 4, in the conventional LCD mounting structure, the LCD 1 is inserted into the metal frame 19a having the LCD display window (corner window) 13 from the lower side with the display surface of the LCD 1 facing upward. After inserting the L-shaped foot 19b of the frame into the fitting groove 33 of the printed wiring board 30 in a state where the rubber connector 20 is in contact with the electrode portion 2 at a right angle and the spacer 40 is interposed, the L-shaped foot 19b is inserted. The structure is such that 19b is bent and fixed.

品実装面積が減少するという問題がある。特に、最近の
電子機器の小型化によって、印刷配線基板自体が小さく
なっているため、ＬＣＤの面積分の部品実装制限は非常
に影響が大きく問題である。However, in the above-mentioned conventional LCD fixture, a spacer is interposed between the printed wiring board and the LCD in order to hold the LCD at a predetermined height position. Therefore, there is a problem that the component mounting area on the printed wiring board is reduced. In particular, the printed wiring board itself has become smaller due to the recent miniaturization of electronic devices, so that the component mounting restriction for the area of the LCD has a great influence and poses a problem.
【０００６】また、ＬＣＤの取付部材としてフレームと
スペーサの二部品が必要となるため、部品点数の増加、
組立工数の増加につながるという問題がある。Further, since two parts, a frame and a spacer, are required as an LCD mounting member, the number of parts increases,
There is a problem that it leads to an increase in assembly man-hours.

合、位置決め精度に欠けるという問題もある。In addition, the outer dimensions of the LCD itself have a large variation in dimensions as compared with general die products due to its manufacture.
The inner size of the frame needs to allow the maximum size of the LCD. Therefore, when the LCD size varies widely, there is also a problem that the positioning accuracy is insufficient.
