BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. The same members or functions as those in FIG. 4 are designated by the same reference numerals.

1 (a) and 1 (b) show a first embodiment of the present invention. A connector housing 11 mounted on the wiring board 8 is provided on the side of the holder portion 4 of the prism 5.
Are arranged. A connector 13 is built in a storage chamber 12 formed in the lower part of the connector housing 11, and a terminal 20 of the connector 13 is soldered to a circuit conductor of the wiring board 8.

A terminal introduction portion 14 having an upper opening is formed at an upper end portion of the connector housing 11, and the terminal introduction portion 14 is formed.
The storage chamber 12 is communicated with the storage chamber 12 via a slit 15.
A tapered surface 16 that is inclined toward the holder portion 4 is formed on one side wall of the terminal introduction portion 14, and the upper opening of the terminal introduction portion 14 is formed to be sufficiently larger than the wall thickness of the terminal 9 of the LCD 2. . On the upper surface of the connector housing 11,
Locking edge member 1 so as to partially close the opening of the terminal introducing portion 14.
7 is attached. The locking edge member 17 has a locking groove 18 formed inside and a tapered surface 19 formed at the upper inside edge.

Next, the process of assembling the LCD 2 will be described.
The LCD 2 is provided with a linear terminal 9 similar to the conventional one, and the terminal 9 is inserted along the tapered surface 16 of the connector housing 11 and the tapered surface 19 of the locking edge member 17. As a result, the tip 9b of the terminal 9 is inserted into the connector 13 through the slit 15 (see FIG. 1B).

The LCD 2 descends in a state of being inclined at an angle corresponding to the taper surface 19, and the back surface 2a of the front end portion of the LCD 2 first comes into contact with the holder portion 4 and is further pressed, as shown in FIG.
When the entire back surface comes into contact with the holder portion 4 as shown in (b), the restoring force of the spring of the terminal 9 pulls the LCD 2 toward the locking edge member 17, and the end edge portion is locked in the locking groove 18. . Therefore, a downward surface pressure 21 is generated on the LCD 2 due to the reaction force received from the locking groove 18, and the LCD 2 is securely fixed without backlash.

2 (a), 2 (b) and 3 show a second embodiment of the present invention. In this embodiment, LC
The terminal 9 of D2 is bent in a dogleg shape through a bent portion 9a in the middle (see FIG. 3). At the bottom of the terminal introduction portion 14 of the connector housing 11, a tapered surface 22 that is continuous with the slit 15 is formed. The locking edge member 17 of the first embodiment is not provided.

As shown in FIG. 2A, when the dogleg-shaped terminal 9 is inserted along the terminal introducing portion 14, the LCD 2 descends in a tilted state corresponding to the bending angle of the terminal 9, LCD2
When the back surface 2a of the tip portion first contacts the holder portion 4 and is further pressed, the entire back surface contacts the holder portion 4 and the tip 9b of the terminal 9 is inserted into the connector 13 as shown in FIG. At the same time, the terminal 9 is straightened in the connector housing 11, and the restoring force of the spring of the terminal 9 at this time causes LC
Surface pressure 21 is generated on the lower surface of D2, and it is securely fixed without backlash.

As described above, in the odtrip devices of the first and second embodiments, when the LCD 2 is set in the holder part 4, the reaction force of the terminal 9 causes a surface pressure to be generated between the LCD 2 and the holder part 4. Since it is fixed by using the bezel, it is possible to prevent backlash without holding it down by the bezel, and it is possible to reduce the number of parts and the number of assembling steps.
By providing the connector housing 11 of the terminal 9
The introduction of the LCD becomes easy, and the automatic assembly of the LCD, which has been difficult in the past, becomes easy.

[0022]

As described above in detail, according to the first aspect of the invention, the reaction force of the terminal causes the surface pressure to be generated between the LCD and the holder portion so as to fix them. Since the bezel for holding down is not required, the number of parts and the number of assembling steps can be reduced, and the terminal introducing portion facilitates the introduction of the connector housing of the terminal and enables the automatic assembly of the LCD. Further, since the bezel is not used, the dial can be attached in contact with the LCD surface, and therefore the depth from the dial surface to the LCD surface can be minimized.

According to the second aspect of the present invention, the locking edge member is provided, and when the LCD is set in the holder portion, one side edge of the LCD is provided in the locking groove of the locking edge member. Since the LCD is locked, one edge of the LCD is suppressed by the locking edge member, and a strong surface pressure of the LCD is generated, so that the play preventing function is further improved.

According to the third aspect of the invention, the LCD is fixed by the reaction force generated by straightening the terminal bent in a dogleg shape in the connector housing. , The LCD can be fixed only by the reaction force of the terminal without using other fixing members, and the configuration and assembly are simplified.

According to the invention of claim 4, a tapered surface is formed on one side wall of the opening having a size larger than the thickness of the terminal, and a slit communicating with the connector is formed from the tapered surface. Since the terminal introduction portion is used, the terminals of the LCD can be easily inserted into the terminal introduction portion, and the LCD assembly of the odotrip device can be easily automated.
