The electrode segments 36a to 36j are arranged and formed so that a neutral range, a drive range, a second speed range, and a low speed range can be specified within a region corresponding to one character. Here, the lamps 50a to 50b for illuminating the electrode portions 34 to 35 of the pattern electrode 33 of the liquid crystal panel 30 will be described with reference to FIG.

Each of the lamps 50a to 50b (1 in FIG. 2)
The lamps 50a to 50c are respectively housed in three cylinders (hereinafter, referred to as cylinders 70) extending from the surface of the circuit board 60. And is connected to the circuit board 40. This cylinder 70
Are fixed to the portion corresponding to the pattern electrode 33 on the back surface of the liquid crystal panel 22 at each opening.

The lamp 50a is located corresponding to the electrode part 34 of the pattern electrode 33, the lamp 50b is located corresponding to the electrode part 35, and the lamp 50c is located corresponding to the electrode part 36. Thus, each lamp is individually turned on to illuminate each corresponding electrode portion. The circuit board 60 is fixed to the bottom wall 41 of the box 40. Next, a driving circuit configuration of the liquid crystal panel 30 and the lamps 50a to 50c will be described with reference to FIG.

The shift switch SW detects a shift operation of the automatic transmission to any one of a parking range, a neutral range, a reverse range, a drive range, a second speed range, and a low speed range. The drive circuit 80 is supplied with power from the battery B via an ignition switch IG, applies a drive voltage between the two electrode substrates of the liquid crystal panel 30 according to the detection range of the shift switch SW, and controls each lamp 50a.
To 50b are turned on.

However, the drive circuit 80 is provided with a shift switch SW
When the detection range is the reverse range, the corresponding lamp 50b is intermittently lit as shown in FIG. 5A and synchronized with the lighting of the lamp 50b as shown in FIG. 5B. To drive the buzzer 90. The buzzer 90 is driven by the drive circuit 80 to generate a buzzer sound. Further, in the pattern electrode 33 of the liquid crystal panel 30, a drive voltage is constantly applied from the drive circuit 80 to the character electrode 34a (representing the character "P") of the electrode portion 34 when the ignition switch IG is turned on. The drive voltage is constantly applied from the drive circuit 80 to the character electrode 35a (representing the character “R”) of the electrode unit 35 when the ignition switch IG is turned on.

The outer frame electrode 34b of the electrode portion 34 (character "P")
The drive voltage is applied from the drive circuit 80 when the detection range of the shift switch SW is the parking range. The drive circuit 80 applies a drive voltage to the outer frame electrode 35b (representing the outer frame of the character “R”) of the electrode unit 35 when the detection range of the shift switch SW is the reverse range.

When the detection range of the shift switch SW is any range other than the reverse range and the parking range, each of the electrode segments 36a to 36j of the electrode section 36 applies a drive voltage from the drive circuit 80 in accordance with the detection range. Applied. The outer frame electrode 36k of the electrode portion 36
When the detection range of the shift switch SW is any range other than the reverse range and the parking range, a drive voltage is applied from the drive circuit 80.

In the first embodiment configured as described above, when the ignition switch IG is turned on, the drive circuit 80 turns on the lamps 50a to 50b.
Then, the lamps 50a to 50b are connected to the liquid crystal panel 22.
The light is emitted toward each corresponding part. When the ignition switch IG is turned on, the drive circuit 80 applies a drive voltage between the character electrode 34a (representing the character “P”) of the electrode portion 34 of the liquid crystal panel 30 and the other electrode substrate.

Then, the light from the lamp 50a passes through the region of the liquid crystal panel 30 including the character electrode 34a.
At the same time, when the ignition switch IG is turned on, the drive circuit 80 applies a drive voltage between the character electrode 35a (representing the character “R”) of the electrode portion 35 of the liquid crystal panel 30 and the other electrode substrate. .

Then, the light from the lamp 50b passes through a region of the liquid crystal panel 30 including the character electrode 35a.
When the automatic transmission is shifted to the parking range in such a state, the shift to the parking range is detected by the shift switch SW. As a result, the drive circuit 80 is connected to the outer frame electrode 3 of the electrode portion 34 of the liquid crystal panel 30
4b (representing the outer frame of the letter "P") and the other electrode substrate, a drive voltage is applied.

Then, the lamp 50 lit as described above is turned on.
The light from a transmits through a region of the liquid crystal panel 30 including the outer frame electrode 34b. Thereby, the liquid crystal panel 30
With the outer frame electrode 34b of the electrode portion 34, the fact that the parking range is set is displayed toward the reflecting surface 21 of the reflecting mirror 20. Therefore, the driver of the vehicle can
On the reflection surface 21 of FIG. 6, it is visually recognized that the parking range is set through the front panel 17 (FIG. 6).
(See (a)).

When the shift to the parking range (or the reverse range) is detected by the shift switch SW, the drive circuit 80 responds to the change of the shift to the parking range (or the reverse range). Each electrode segment 36b, 36c, 36f, 36i, 36
A drive voltage is also applied between g and 36j (representing the character “N”) and the other electrode substrate.

Therefore, the light from the lamp 50c is applied to each of the electrode segments 36b, 36c, 36 of the liquid crystal panel 30.
The light passes through the region including f, 36i, 36g, and 36j.
Here, when the automatic transmission is shifted to the reverse range, the shift to the reverse range is detected by the shift switch SW. Then, the drive circuit 80 intermittently lights the corresponding lamp 50b that is being turned on. Therefore, the lamp 50b emits light intermittently.

Then, the drive circuit 80 drives the buzzer 90 in synchronization with the lighting of the lamp 50b. Then, the buzzer 90 generates a buzzer sound. Further, the drive circuit 80 stops applying a drive voltage between the outer frame electrode 34b (representing the outer frame of the character “P”) of the electrode portion 34 of the liquid crystal panel 30 and the other electrode substrate, and the drive circuit 80 Reference numeral 80 applies a drive voltage between the outer frame electrode 35b (representing the outer frame of the character "R") of the electrode portion 35 of the liquid crystal panel 30 and the other electrode substrate.

Therefore, the light from the lamp 50a being lit does not pass through the region including the outer frame electrode 34b of the liquid crystal panel 30, while the light from the lamp 50b intermittently changes the outer frame of the liquid crystal panel 30. The light passes through a region including the electrode 34b. As a result, the liquid crystal panel 30 uses the outer frame electrode 35b of the electrode portion 35 to display the fact that the reverse range is set toward the reflecting surface 21 of the reflecting mirror 21 by intermittent light.

Therefore, the driver can use the reflecting surface 21 of the reflecting mirror 20.
Above, it is visually recognized through the front panel 17 that the reverse range is set (see FIG. 6B). At the same time, the driver is informed of the reverse range by the intermittent buzzer sound of the buzzer 90. Next, when the automatic transmission is shifted to any range other than the reverse range and the parking range, any range other than the reverse range and the parking range is detected by the shift switch SW.

Then, the drive circuit 80 stops driving the buzzer 90 and constantly lights the lamp 50b. Further, the drive circuit 80 stops applying the drive voltage between the outer frame electrode 35b (representing the outer frame of the character “R”) of the electrode portion 35 of the liquid crystal panel 30 and the other electrode substrate, and the drive circuit 80 A drive voltage 80 is applied between the outer frame electrode 36k of the electrode section 36 of the liquid crystal panel 30 (representing the outer frame of each electrode segment) and the other electrode substrate.

Therefore, the light from the lit lamp 50b does not pass through the region including the outer frame electrode 35b of the liquid crystal panel 30, while the light from the lamp 50c is not transmitted through the outer frame electrode of the liquid crystal panel 30. The light passes through an area including 36k.
Then, the drive circuit 80 applies a drive voltage between a corresponding one of the electrode segments 36a to 36j of the electrode portion 36 of the liquid crystal panel 30 corresponding to the detection range of the shift switch SW and the other electrode substrate.

Therefore, the light from the corresponding lamp 50c is
The light passes through a region of the liquid crystal panel 30 including the corresponding electrode segment. As a result, the liquid crystal panel 30 displays to the reflecting mirror 20 that the current range is one of the neutral range, the drive range, the second speed range, and the low speed range by the corresponding electrode segment.

Therefore, the driver can operate the reflecting surface 2 of the reflecting mirror 20.
In FIG. 6 (c), it is visually recognized through the front panel 17 that the selected range is any of the neutral range, the drive range, the second speed range, and the low speed range.
(See (d), (e) and (f)). As explained above,
In one electrode substrate of the liquid crystal panel 30, the electrode portion 34
(Representing a parking range) and an electrode portion 35 (representing a reverse range) were formed separately from an electrode portion 36 (representing a shift range other than the parking range and the reverse range).

For this reason, in the liquid crystal panel, an electrode section for specifying a plurality of shift ranges by a selective combination of a plurality of electrode segments in a region corresponding to one character (in the first embodiment, the electrode section 36 is used). ) Of the electrode segment can be reduced as compared with the related art. As a result,
A shift range by an electrode unit (in the first embodiment, it means the electrode unit 36) that specifies a plurality of shift ranges by a selective combination of a plurality of electrode segments in a region corresponding to one character in the liquid crystal panel. Display became easier to see. That is, in the first embodiment, the display of the neutral range, the drive range, the second speed range, and the low speed range is more easily recognized than in the related art.

The indicator in the first embodiment uses three electrode parts 34 to 36 to indicate the respective shift ranges. On the other hand, as a conventional indicator, there is an indicator which displays each shift range in a vertical or horizontal direction. The indicator of the first embodiment can reduce the display space as compared with such a conventional indicator.

As described above, the drive circuit 80 drives the buzzer # 90 in synchronization with the lighting of the lamp 50b. Therefore, the circuit configuration for driving buzzer # 90 is simplified. In the first embodiment, an example has been described in which the drive circuit 80 intermittently lights the lamp 50b when the automatic transmission is in the reverse range, and drives the buzzer # 90 in synchronization with the lighting. However, the present invention is not limited thereto, and the driving circuit 80 intermittently turns on the lamp 50b as shown in FIG.
As shown in FIG. 7B, the buzzer # 90 may be driven in synchronization with the turning off of the lamp 50b.

Further, in the first embodiment, an example is described in which the liquid crystal panel 22 is employed to display the parking range and the reverse range. However, the present invention is not limited to this. A display panel in which the effect is printed may be employed. In this case, in displaying the indicator, the liquid crystal panel 30 has only the ten electrode segments 36a to 36j without the character electrodes 34a and 35a and the outer frame electrodes 34b and 35b. .

Thus, the conventional indicator (FIG. 10)
And 14 FIG. 11).
Four electrode segments can be reduced as compared with the case where each shift range is displayed by a to 2 m. Therefore, the electrical connection between the drive circuit 80 and the liquid crystal panel 30 can be simplified.

In the first embodiment, the parking range and the reverse range are displayed by the corresponding outer frame electrodes 34b and 35b as described above. However, the present invention is not limited to this. The outer frame electrode 34b may be omitted, and the operation may be performed with the corresponding character electrodes 34a and 35a. In this case, the drive circuit 80 does not always apply a voltage between the character electrode 34a and the other electrode substrate as described above, but only when the shift to the parking range is detected, A drive voltage is applied between the substrate and the electrode substrate.

At the same time, the drive circuit 80 does not always apply a voltage between the character electrode 35a and the other electrode substrate, but only when a shift to the reverse range is detected. A voltage is applied between the electrode substrate. As a result, the number of electrode segments of the liquid crystal panel 30 is reduced to the two character electrodes 34a, 35a, the ten electrode segments 36a to 36j, and the outer frame electrode 36a.
k of thirteen.

Therefore, the number of electrode segments is reduced by one as compared with the case where each shift range is displayed by 14 electrode segments as in the prior art, so that the distance between the drive circuit 80 and the liquid crystal panel 30 is reduced. Simplifies the electrical connection configuration. Further, the outer frame electrode 36k of each of the electrode segments 36a to 36j may be omitted. in this case,
Since the number of electrode segments is one less than in the related art, the electrical connection between the drive circuit 80 and the liquid crystal panel 30 is further simplified.

(Second Embodiment) A second embodiment of the present invention will be described with reference to FIG. In the second embodiment, the pattern electrode section 33 of the liquid crystal panel 30 is provided with the electrode section 36 (electrode segments 36a to 36a) described in the first embodiment.
j) is formed.

The electrode section 37 includes five electrode segments 37a to 37e in a region corresponding to one character of the liquid crystal panel 30 in a drive range other than the parking range, the reverse range, the neutral range, the second speed range, and the like. It is arranged and formed so that the low-speed range can be specified. Other configurations are the same as those of the first embodiment.

In the second embodiment configured as described above, when the automatic transmission is shifted to a range other than the reverse range, the parking range, and the neutral range, the automatic transmission is set to a position other than the reverse range, the parking range, and the neutral range. Is detected by the shift switch SW. Then, the drive circuit 80 applies a drive voltage between the corresponding electrode segment corresponding to the detection range of the shift switch SW and the other electrode substrate among the electrode segments 37a to 37e of the electrode portion 37 of the liquid crystal panel 30.

Therefore, the light from the corresponding lamp 50c is
The light passes through a region of the liquid crystal panel 22 including the corresponding electrode segment. As a result, the liquid crystal panel 30 displays to the reflecting mirror 20 that the current range is one of the drive range, the second speed range, and the low speed range by the corresponding electrode segment.

Therefore, the driver can operate the reflecting surface 21 of the reflecting mirror 20.
Above, it is visually recognized through the front panel 17 that any of the drive range, the second speed range, and the low speed range is provided (see FIGS. 9A, 9D, and 9C). As described above, the five electrode segments 37a to 37e of the electrode unit 37 are provided with the parking range,
The drive range, the second speed range and the low speed range other than the reverse range and the neutral range are specified.

For this reason, an electrode section for specifying a plurality of shift ranges by a selective combination of a plurality of electrode segments in a region corresponding to one character in the liquid crystal panel (in the second embodiment, the electrode section 37 is not used). ) Can be reduced compared to the first embodiment. As a result, in the area corresponding to one character of the liquid crystal panel, the display of the shift range by the electrode unit (meaning the electrode unit 37) specifying the plurality of shift ranges by the selective combination of the plurality of electrode segments is further visually recognized. It became easy to do. That is, in the second embodiment, the display of the drive range, the second speed range, and the low speed range is more easily visually recognized than in the first embodiment.

In implementing the present invention, the display of the parking range, the reverse range and the neutral range in the second embodiment is not performed by the liquid crystal panel, but the parking range, the reverse range and the new range are displayed on the transparent plate member. The indication of each of the neutral ranges may be displayed on a display panel formed by printing. In this case, only five electrode segments 37a to 37e are used for display by the indicator, so that the number of electrode segments can be reduced by five as compared with the first embodiment. As a result, the electrical connection between the drive circuit 80 and the liquid crystal panel 22 is further simplified.

In each of the above embodiments, an example has been described in which the electrode segments of the liquid crystal panel 30 are employed as display segments. However, the present invention is not limited to this.
EL and LED may be adopted.
