Of course, when intermittent current is input to the processing unit 32 from both the second left wiring 86 and the second right wiring 87, both the left turn symbol 40 and the right turn symbol 41 are displayed on the image display unit 31. Thus, by displaying the left turn symbol 40 and the right turn symbol 41 simultaneously, the parking / stopping state is displayed to the driver.

  In addition, when an intermittent current is input from the second left wiring 86 to the processing unit 32, the processing unit 32 outputs a sound that tells the driver to turn left through the sound reporting unit 33, and the second right wiring 87. When the intermittent current is input to the processing unit 32, a sound is output that informs the driver of the right turn through the sound reporting unit 33. Furthermore, when an intermittent current is input to the processing unit 32 from the second left wiring 86 and the second right wiring 87, the processing unit 32 outputs a voice that informs the driver that the vehicle is parked via the sound reporting unit 33. To do. In the above example, the operation state of the vehicle is transmitted to the driver by voice, but the operation state of the vehicle may be transmitted to the driver by a buzzer.

  Next, the blinking operation of the left and right turn lamps 74 and 75, the display of the turn symbols 40 and 41, and the blinking operation of the turn indicator lamp 63 (turn operation mark 53) will be described with reference to FIG. First, the case where the ignition switch 76 is in the on state, that is, the case where the flasher relay 70 and the processing unit 32 are in the driving state will be described. When the left turn switch 72 a is turned on by a user operation, an intermittent current is output from the flasher relay 70 to the first left wiring 82. The intermittent current output to the first left wiring 82 is input to the left turn lamp 74, the processing unit 32, and the turn indicator lamp 63 via the above-described current path. As a result, the left turn lamp 74 blinks, the left turn symbol 40 is displayed on the image display unit 31, and the turn indicator lamp 63 (turn operation mark 53) blinks. Then, it is notified by voice that a left turn is made from the reporting unit 33.

  On the other hand, when the right turn switch 72b is turned on by a user operation, an intermittent current is output from the flasher relay 70 to the first right wiring 83. The intermittent current output to the first right wiring 83 is input to the right turn lamp 75, the processing unit 32, and the turn indicator lamp 63 via the above-described current path. As a result, the right turn lamp 75 blinks, the right turn symbol 41 is displayed on the image display section 31, and the turn indicator lamp 63 (turn operation mark) blinks. And it is alert | reported by a voice | voice that the report sound part 33 turns right.

  When the user operates not the direction indicator 72 but the parking / stop indicator 73 and the parking / stop switch 73a is turned on, an intermittent current is output from the hazard relay 71 to the left connecting wire 89 and the right connecting wire 90. The As described above, the left connection wiring 89 is electrically connected to the first left wiring 82, and the right connection wiring 90 is electrically connected to the first right wiring 83. Therefore, the intermittent current of the hazard relay 71 is input to the left and right turn lamps 74 and 75, the processing unit 32, and the turn indicator lamp 63 via the above-described current path. As a result, the left and right turn lamps 74 and 75 blink, the left turn symbol 40 and the right turn symbol 41 are simultaneously displayed on the image display unit 31, and the turn indicator lamp 63 (turn operation mark 53) blinks. Then, it is notified by voice that the vehicle is parked and stopped from the reporting unit 33.

  Next, the case where the ignition switch 76 is in an off state, that is, the case where the flasher relay 70 and the processing unit 32 are in an off state will be described. In this case, even if the user operates the direction indicator 72, the flasher relay 70 is in an off state, and therefore no intermittent current is output from the flasher relay 70. Accordingly, when the direction indicator 72 is operated, the left and right turn lamps 74 and 75 do not blink, and the turn indicator lamp 63 (turn operation mark 53) does not blink. Further, since the processing unit 32 is also in an off state, the segments 35 to 39 are not displayed on the image display unit 31. On the other hand, since the hazard relay 71 is directly connected to the battery 77, the hazard relay 71 can be driven regardless of whether the ignition switch 76 is on or off. Therefore, when the parking switch 73 a is turned on by the user's operation, an intermittent current is output from the hazard relay 71 to the left connecting wire 89 and the right connecting wire 90. As a result, the left and right turn lamps 74 and 75 blink, and the turn indicator lamp 63 (turn operation mark 53) blinks. Although intermittent current is also input to the processing unit 32, the processing unit 32 is in an off state, so that the turn symbols 40 and 41 are not displayed on the image display unit 31, and the notification sound from the sound reporting unit 33 is displayed. There is no output.

  Next, the function and effect of the combination meter 100 according to the present embodiment will be described. As described above, when the ignition switch 76 is in the on state, the flasher relay 70, the processing unit 32, and the hazard relay 71 are in the drive state. However, when the ignition switch 76 is in the off state, only the hazard relay 71 is in the drive state. Therefore, when the ignition switch 76 is on, at least one of the left and right turn lamps 74 and 75 is blinked by the intermittent current of either the flasher relay 70 or the hazard relay 71, and the left turn symbol 40 and the right turn are displayed on the image display unit 31. At least one of the symbols 41 is displayed, and the turn indicator lamp 63 (turn operation mark 53) blinks. In addition, when the ignition switch 76 is in an OFF state, the left and right turn lamps 74 and 75 are blinked by the intermittent current of the hazard relay 71, the turn symbols 40 and 41 are not displayed on the image display unit 31, and the turn indicator lamp 63 ( The turn operation mark 53) blinks.

  As described above, according to the combination meter 100 according to the present embodiment, even when the number of the turn indicator lamp 63 is one, the turn operation mark is accompanied by the blinking operation of the left and right turn lamps 74 and 75 with the ignition switch 76 turned on. 53 is displayed in a blinking manner, and turn symbols 40 and 41 indicating any one of a left turn, a right turn, and a parking stop are displayed on the image display unit 31. Therefore, left and right turn lamps 74 provided outside the vehicle, The driver can clearly discriminate between 75 blinking operations. In addition, when the ignition switch 76 is in the OFF state, the turn operation mark 53 blinks in accordance with the blinking operation of the left and right turn lamps 74 and 75. Therefore, the driver clearly indicates the blinking operation of the left and right turn lamps 74 and 75. Can be determined.

The turn symbols 40 and 41 shown are displayed. According to this, for example, an image display is performed using a dedicated display mark as compared with a configuration in which a symbol indicating whether the vehicle is in a left turn, a right turn, or a parking stop is displayed on the image display unit 31. The number of segments displayed on the part 31 can be reduced.

  When the ignition switch 76 is on, the left turn symbol 40 is displayed on the image display unit 31 as the left turn lamp 74 blinks, and the right turn symbol 41 is displayed as the right turn lamp 75 blinks. . As described above, the left turn symbol 40 is constituted by the symbol segment 38 arranged on the left side, and the right turn symbol 41 is constituted by the symbol segment 38 arranged on the right side. Accordingly, since the blinking operation of the left and right turn lamps 74 and 75 and the position of the displayed turn symbols 40 and 41 coincide, the driver can easily blink the left and right turn lamps 74 and 75 mounted outside the vehicle. Can be determined.

  In the present embodiment, parking is indicated by both the left turn symbol 40 and the right turn symbol 41. According to this, the types of symbols displayed on the image display unit 31 are reduced compared to the configuration in which the symbol indicating parking and stopping is displayed on the image display unit 31, which is different from the left turn symbol 40 and the right turn symbol 41. Is done.

  The combination meter 100 according to the present embodiment includes a sound report unit 33 that conveys the operating state of the vehicle to the driver by sound. According to this, when the ignition switch 76 is in the on state, the driver does not need to visually recognize the image display unit 31 or the turn operation mark 53 at any of the left turn, the right turn, and the parking stop. Can be perceived.
