A diffuser plate 37 or a holster 30 is placed on the back side of the liquid crystal upper panel 29, and this diffuser plate 37 spreads the light from the fluorescent lamp 38, which is the source of illumination T', and spreads the light evenly across the liquid crystal display panel 28. It will also be incident '+6-.

The fluorescent lamp 18 is, for example, a -I wavelength type high heat end high brightness 716 W type, and this fluorescent lamp 38 is placed horizontally with R + i in the Y row. , silicon 7
It is screwed to the lower case 32 via a musokerat 39. Further, since both ends of the filament 40 are supported by the electrodes 41, a natural frequency exists around approximately 67 Hz.

For this reason, the silicone rubber socket 39 is provided with a damper effect, and the filament 40 is oriented perpendicular to the road surface, which is less affected by the acceleration that the vehicle receives while driving, to provide salt resistance. There is. moreover,'
The power supply to the electrode 41 does not use gold and is directly soldered to the electrode pin to prevent non-lighting and flickering due to poor contact due to vibration.

The inner surface of the lower case 32 is made of white material or painted to increase light reflectance. moreover.

The diffusion plate 37 is made of a semi-transparent white acrylic plate, and has the effect of blocking heat generated by the fluorescent lamp 38. For light emission at low temperatures, an illumination chamber is formed by the lower case 32 and the acrylic plate of the diffuser &37, so the temperature of the fluorescent lamp 38 rises and the luminance of the light rises with time, ensuring a predetermined value. be done.

The display electrode of the liquid crystal cell 29 is connected to a printed circuit board 43 arranged on the back side of the lower case 32 via a beam wire 42 .

Light is guided from the fluorescent lamp 38 of the correction part to each button part 45 via an acrylic light guide 48 to illuminate each button part 45. In this way, since the case 32 including the keyboard portion 17 integrally forms the illumination room, there is no need to provide a key-dedicated lamp.

The liquid crystal cell 29 employs a TN transmission type, and is constructed as shown in FIG. 11.

An upper glass plate 50 and an F plate glass 51 are arranged on both sides of the liquid crystal 49, and a 1-E claw 5 is provided on the top surface of the first glass plate 50.
2, a lower polarizing plate 53 is disposed on the lower surface of the flat glass 51. Printing is performed on the lower surface of the lower polarizing plate 53,
A black mask printing section 54 and a color printing section 55 are formed.

The transparent display electrode shown in No. 141A is arranged loosely between the liquid crystal 49 and the lower glass plate 51.
When a voltage is applied to these display electrodes, light is transmitted through the liquid crystal 49, and is blocked when no voltage is applied.

The color printing section 55 is a section that forms characters, numbers, annular scene displays, etc. of the display section 16, and is printed in a desired color. The dimensions used for this printing and the ink used are transparent. Black: "The screen printing section 54 is the back 1 (part) of the display section 16. Since no electrode is provided in this section, no light is transmitted through the application of a voltage. That is, C; 8 is used to block the light, but since it is difficult to completely block the light due to the nature of liquid crystal, the liquid crystal 49 is used as a light shutter by physically blocking the light.

The liquid crystal segment of the display section 16 is constructed as shown in FIG. 12, and the traveling speed display section 19. Fuel cost 'j1 display section 20
The display is a concentric annular zone display, each with a part cut out to the center.

The notches 56 and 57 display the traveling speed and the amount of fuel remaining, and the warning display parts 19a and 20a in the center are arranged in four positions so as to be extinguished.

The pattern layout is divided into two parts 61b, 60d, and 61d, and the load capacitance is averaged.

The segment electrodes 58 and the common electrodes 59 are driven by applying a drive waveform of 1/2 duty and 1·'2 bias, and the annular sheet display section 60 is lit radially from the inside to the outside in order to display the display section. The area of the annular zone display section 61 is entirely lit, and the area of the annular zone display section 61 is gradually turned off in a radial direction from the outer JT toward the inside, thereby decreasing the area of the display section. By adopting such a multiplex drive system, it is possible to connect two annular zone display sections to one display electrode. Note that a static drive method may be adopted in which all segment electrodes 58 are driven independently.

Furthermore, the notches 62a and 62b of the segment electrodes, poles 58, and common electrodes 59 are formed so as to spread outward in a wedge shape, and the connecting wires 6 from this concentric annular zone display section 60
A routing space of 4,66,72,75 is secured. Furthermore, the notch 62a of the segment electrode 58 and the notch 6

In the verification mode where the speed signal is not manually input, the traveling speed display section 19 displays numbers 1 and 0 to 60 Km/h, etc., and the annular zone display section up to 30 Km/h is dark yellow, and the warning display sections 19a and 30 in the center are displayed. The annular zone display section for ~60 Km/h is colored dark red to suggest the display range of travel speed compared to the other black areas.

When a driving voltage based on a speed signal is applied to these, the color becomes brightly reduced or red, and the contrast between when the voltage is applied and when it is not applied is well maintained.

In this example, the zone resolution is every 2.5 Km/h, the adjacent spacing is 1.0 mm every 10 Km/h, and 5 K m
/H is set to 0.5mm, and other parts are set to 0°3mm to make it easy for riders to read.

As the speed signal increases, the liquid crystal annular zone display section 60 expands radially to increase its display area.
If the vehicle exceeds Km or 'h, the warning display section 19a at the center of the zone will turn red and act as a speed warning. Sara 11. The degree increases, and the 1-limit of the L quantity zone display section is 60 km,・'h
Even if the number exceeds 6, Table 2i is 6
It continues to display 0Km/h.

117f Remaining fuel [The A display section 20 has a 4-level zone display. The more fuel remains, the larger the zone becomes. As fuel is consumed, the remaining 111 decreases, and the zone display becomes smaller toward the center. Therefore, the area of the display section is reduced. Then, when the annular zone is displayed or the crosspiece is smaller than a predetermined value, the level display starts and the warning display section 20a blinks.

The trip meter/time display section 21 normally displays the time when the system is on, and when the mode key 23 of the keyboard section F is pressed, it becomes a trip meter, and switches each time it is pressed.

The display on the trip meter is 0.1+1'j-.

4-digit display from 0.0 to 999.9. The display switching cycle is 0. For each IKm, the display data is changed and the liquid crystal display is changed when the integrated value of distance pulses from a not-shown leet switch reaches OIKm.
