To 9 are visually recognized.

Next, the electrical configuration of the pointer type display device in this embodiment will be described with reference to FIG. First, the pointer light source 7, the light-emitting area light source 8, and the scale plate light source 9 are systems in which turning on and off are controlled by a control means 10 comprising a microcomputer.

1c.

The key switch 11 is set to O by the user.
When operated from the FF position 11a to the ACC position 11b,
When the power supply from the battery 12 to various electric devices is started, and subsequently the ACC position 11b is operated to the IGN position 11c, the ignition device is activated and the engine is started. Thereby, the rotation sensor 13 detects the number of rotations of the engine,
The detection signal is input to the control means 10 as an input signal (power-on signal). In this embodiment, an engine start state in which an input signal from the rotation sensor is present is defined as a power-on state.

Further, the IGN position 11c is temporarily set by the user.
After that, the key switch 11 operated by the user is returned to the ACC position 11b again by the user, whereby the operation of the ignition device is stopped, but the power-on state (engine operation state) is continued. Then, when the user operates the key to the OFF position 11a from this state, the power supply to various electrical devices is cut off and the engine is stopped at the same time. In this embodiment, the power is turned off in this embodiment. When the key switch 11 is operated from the ACC position 11b to the OFF position 11a, the control means 10 receives an input signal (power-off signal) from the key switch 11.

Next, the processing procedure of the control means 10 in response to the operation of the key switch 11 will be described with reference to FIG. Here, the user turns the key switch 11 from the OFF position 11a to AC.
It is assumed that the operation is performed from the C position 11b to the IGN position 11c. First, in step S1, the control means 10 determines whether or not the power is on (whether or not the engine has started) based on an input signal (power-on signal) from the rotation sensor.

"YES (ON state)" in step S1
Is determined, the pointer light source 7 is determined in step S2.
Then, a lighting process of the scale plate light source 9 is performed. As a result, the indicator 41 of the pointer 4 emits light linearly to form a light emitting indicator, and the colored layer (measured value display) 53 emits light to form a light emitting display. This lighting process turns on the pointer light source 7 and the scale plate light source 9 substantially simultaneously.
It can also be turned on with a time difference. Further, each of the light sources 7 and 9 may be turned on so that the light emission luminance gradually increases.

It is determined whether or not a predetermined time (arbitrarily settable) has elapsed,
If the predetermined time has elapsed and it is determined to be “YES”,
In step S4, the light source 8 for the light emitting area is turned on. Thus, the light emitting area light source 8 is turned on a predetermined time after the pointer light source 7 and the scale plate light source 9 are turned on, and the light emitting instruction unit of the instruction unit 41 and the measured value display unit (colored layer) 53 are used. In addition to the light emitting display unit, the light emitting region R is visually recognized around the light emitting instruction unit. The above is the lighting processing procedure of each of the light sources 7 to 9.
When the light emitting region R is rotated according to the measured amount, the light emitting region R is visually recognized as a tail of light rotating following the light emitting instruction portion.

Next, a procedure for turning off the light sources 7 to 9 will be described. The control means 10 first determines whether or not the power is off based on an input signal (power-off signal) from the key switch 11 in step S5. If the determination is "YES (off state)", the process proceeds to step S6, where the light emitting region light source 8 is turned off, whereby the light emitting region disappears immediately. If it is determined “NO (not in the OFF state)” in step S5, the lighting state of the light source 8 for the light emitting area is maintained. Thereafter, in step S7, the light source 7 for the pointer and the light source 9 for the scale plate are turned off. As a result, after the light source 8 for the light emitting region is turned off first, the light source 7 for the pointer and the light source 9 for the scale plate are turned off, and the light emitting instruction portion and the light emitting display portion disappear after the light emitting region R. Note that a determination process such as step S3 may be performed between step S6 and step S7,
Also in the process of turning off each of the light sources 7 to 9 in step S6 and step S7, a process may be performed so that each of the light sources 7 to 9 gradually reduces the emission luminance. After the power is turned off, the power supply from the battery 12 to the control unit 10, the pointer light source 7, and the scale light source 9 is cut off. However, by using a backup power supply (not shown), the control unit 10, the pointer light source 7,
Electric power can be supplied to the scale plate light source 9.

By turning off the light source 7, the light emitting region R can be formed after the light emitting instruction portion is formed when the light source 7 is turned on, and the light emitting instruction portion can be turned off after the light emitting region R is turned off when the light source 7 is turned off. At the time of lighting, a light emitting instruction portion serving as a main element in performing the pointer type display can be visually recognized first, and subsequently, a light emitting region serving as a sub element can be visually recognized. After that, the light-emission instructing unit serving as a main element can be erased, whereby an expression method according to the ordering from the master to the slave can be established, and the display quality can be improved. Note that such a lighting / lighting-off process may be performed either at the time of lighting or at the time of lighting-out.

It is determined whether the power is off. If "YES (OFF state)" is determined in step S15, the process proceeds to step S16, in which the light sources 7 to 9 are simultaneously turned off.
The light emission instruction unit, the light emission display unit, and the light emission region R disappear almost simultaneously. If it is determined as “NO (not in the power-off state)” in step S15, the lighting state of each of the light sources 7 to 9 is maintained.

In this embodiment, as in the first embodiment, at the time of turning on each of the light sources 7 to 9, at least one of them is controlled so as to gradually increase the light emission luminance. When the light sources 7 to 9 are extinguished, the extinguishing control may be performed so that the emission luminance gradually decreases. In the turn-off processing, after step S15, the turn-off processing may be performed in a predetermined order similar to steps 6 and 7 of the first embodiment.

As described above, in this embodiment, the pointer type display formed by the scale plate 5 and the pointer 4 (indicator 41) constitutes a display for displaying the engine speed of the vehicle, and the switch is used for the vehicle. The first light sources 7 and 9 are turned on in response to a first input signal (power-on signal) from the key switch 11. To form a light emitting region R by turning on the second light source 8 in response to a second input signal from the rotation sensor that is subsequently input, thereby forming the light emitting region R. In addition to the same effect as the example, in addition to preventing the light emitting region R from being formed when the light emitting instruction unit (instruction unit 41) without the input signal from the rotation sensor 13 is stopped, the input signal from the rotation sensor 13 is provided. Activation of the flash indicator ( Since only capable of forming a light-emitting region R when rolling), expression technique (so-called light emitting region R to follow the emission instruction unit, to improve the degree of completion of the radar image), it is possible to improve display quality and marketability.

In addition to the operation control described above, the light-emitting area light source 8 is used in accordance with an input signal from the speed sensor 14 to execute the light-emitting area light source 8.

In this embodiment, as in the second embodiment, when the key switch 11 is operated from the OFF position 11a to the ACC position 11b, an input signal comprising a power ON signal is changed from the ACC position 11b to the OFF position 11a. When the operation is performed, the input signal including the power-off signal is input to the control means 10, and when the key switch 11 is operated from the ACC position 11b to the IGN position 11c and the engine is started, the input signal from the rotation sensor 13 is output.

At step S21, the power is turned on ("YE
S "), the lighting process of the pointer light source 7 and the scale plate light source 9 is performed in step S22. Thus, the indicator 41 of the pointer 4 emits light linearly to form a light emission indicator, and the colored layer (measured value display) 53 emits light to form a light emitting display.

After the processing of step S22, step S23
It is determined whether or not the engine is started based on the input signal from the rotation sensor 13 and the engine is started (“Y
If "ES") is determined, the process proceeds to step S24, where it is determined whether or not the vehicle is in a traveling state based on an input signal (second input signal) from the speed sensor 14.

If "YES (vehicle is running)" is determined in step S24, the light emission area light source 8 is turned on in step S25. Thus, the pointer light source 7 and the scale plate light source 9 are turned on (step S22).
After that, a predetermined process (step S23 and step S2)

These are the light sources 7 to 9
When the hands 4 are rotated through the driving device 3 according to the measured amount after the end of these processing procedures,
The light-emitting region R is visually recognized as a tail of light that rotates following the light-emitting instruction portion. At this time, for example, the speed sensor 1
The rotation direction (increase instruction direction or decrease instruction direction) of the pointer 4 is determined (arithmetic processing) in accordance with the input signal from the control unit 4, and at least one of the light sources 7 to 9 is determined according to the result of the determination (processing). For example, the light emitting area light source 8 is turned on and off,
Alternatively, the light emission luminance may be adjusted, or the amount of change in the input signal from the speed sensor 14 may be determined (arithmetic processing), and the light emission luminance may be changed according to the result of the determination (processing).

Next, the procedure for turning off the light sources 7 to 9 will be described. The control means 10 first determines in step S26 whether or not the vehicle is in a stopped state based on an input signal from the speed sensor 14, and when it is determined that "YES (the vehicle is in a stopped state)". In step S27, the light emitting area light source 8 is turned off. If the determination is "NO (the vehicle is not in a stopped state)", the lighting state of the light emitting region light source is continued. Thereafter, in step S28, the rotation sensor 1
It is determined whether or not the engine is stopped based on the input signal from the control unit 3 and if "YES (engine stop)" is determined, the pointer light source 7 and the scale light source 9 are determined in step S29.

As described above, in this embodiment, the pointer type display formed by the scale plate 5 and the pointer 4 (indicator 41) constitutes a display for displaying the speed of the vehicle, and the switch is a key for the vehicle. The first light source 7 is turned on in response to a first input signal (power-on signal) from the key switch 11 to emit light. An indicator can be formed, and the second light source 8 can be turned on in response to a second input signal from the speed sensor that is subsequently input to form the light emitting region R. In addition to similar effects,
This prevents the light emission region R from being formed when the light emission instruction unit (instruction unit 41) without the input signal from the speed sensor 13 is stopped, and prevents the light emission instruction unit with the input signal from the speed sensor 13 from operating (rotating). Since only the light emitting region R can be formed, it is possible to improve the degree of perfection of an expression method (a so-called radar image) in which the light emitting region R follows the light emitting instruction portion, and it is possible to improve display quality and commercial value.
