One side of the two sides constituting the L-shape is positioned below the overlapping portion 21d, and the other side is positioned immediately next to the frame portion 42 as a specific portion other than the overlapping portion 21d. That is, the incident surface 26a of the light guide part 26 is positioned not next to the overlapping part 21d but next to the overlapping part 21d.

  An LED 75 as a light source for light guide that irradiates light to the incident surface 26 a is mounted on the substrate 60 at a position facing the incident surface 26 a of the light guide unit 26. The light from the LED 75 enters the light guide portion 26 from the incident surface 26 a and travels along the L-shape of the light guide portion 26 while reflecting the inside of the light guide portion 26. A part of the light passes through the overlapping portion 21d. Thereby, the overlapping portion 21d emits light.

  In addition to the overlapping portion 21d shown in FIG. 3, other overlapping portions 11c, 11d, and 21c are also provided with light guides for emitting light from the overlapping portions 11c, 11d, and 21c, respectively, as in FIG. 60 is mounted with an LED as a light guide light source for irradiating each light guide portion with light.

  Next, the electrical configuration of the vehicle meter unit 1 will be described. Here, FIG. 5 is a block diagram showing an electrical configuration of the vehicle meter unit 1. In FIG. 5, in addition to the vehicle meter unit 1, other configurations (body ECU 90 and the like) related to the operation of the vehicle meter unit 1 are also illustrated. As shown in FIG. 5, the electrical configuration of the vehicle meter unit 1 includes a control unit 83 (see FIG. 2) mounted on the substrate 60 as a main part and is electrically connected to the control unit 83. The display device 40, the stepping motor 82, the LEDs 71 to 75, and the mode setting SW 84 are included.

The ROM 832 stores various programs to be executed by the CPU 831. Specifically, the ROM 832 controls the stepping motor 82, which is an image display program that indicates what kind of image is displayed on the display device 40 at what timing. A motor control program to be performed, an LED control program to control lighting of the LEDs 71 to 75, and the like are stored. As described above, the display device 40 displays a connection image that connects the end portions 11a, 11b, 21a, and 21b of the meter frames 11 and 21, so the ROM 832 displays the connection image. The image data shown is stored as part of the image display program. In addition, the connection image displayed on the display device 40 differs depending on the mode. For this reason, the ROM 832 stores image data indicating the connection image for each mode. The RAM 833 is used to temporarily store various data when the CPU 831 executes various processes.

  A mode setting SW 84 connected to the input / output unit (I / O) 835 is a switch for setting a mode for changing the display impression of the vehicle meter unit 1.

The physical quantities related to the vehicle state are, for example, the vehicle speed, the engine speed, the average fuel consumption, the fuel remaining amount, the shift position, the outside air temperature, the cooling water temperature, and the battery remaining amount, and the control unit 83 converts these measured values into the body ECU 90. Is getting from.

  Various sensors 92 (for example, a vehicle speed sensor, a coolant temperature sensor, a remaining fuel sensor, a shift position sensor, etc.) for measuring these physical quantities are connected to the body ECU 90. The body system ECU 90 transmits the values of the various sensors 92 to the control unit 83 as measured values for reflecting the values on the meters 10 and 20 and the display device 40.

  In addition, a vehicle (not shown) on which the vehicle meter unit 1 of the present embodiment is mounted is provided with clearance sonars (included in various sensors 92) at five locations in the corners and the center of the rear of the vehicle. The body system ECU 90 also acquires the measurement value of each clearance sonar. The control unit 83 also acquires the measurement values of the clearance sonars from the body system ECU 90 in the (D) back mode.

  Further, the vehicle on which the vehicle meter unit 1 is mounted is a hybrid vehicle, and the body system ECU 90 has information indicating the charging status of the battery and the driving ratio between the engine and the motor in order to drive the motor of the vehicle. Information on hybrid driving is also acquired. In the (C) eco mode, the control unit 83 also acquires information related to the hybrid travel from the body system ECU 90.

  Next, how the meters 10 and 20 and the display device 40 are displayed in each mode will be described. Note that the display of the display device 40 is performed by the CPU 831 of the control unit 83. Specifically, the CPU 831 reads out image data to be displayed from the ROM 832 according to an image display program and draws a drawing circuit (based on each image data). A basic image is generated on a graphic memory (not shown). Further, when displaying the measurement value on the display device 40, the drawing data reflecting the measurement value is created in the drawing circuit, and is combined with the basic image on the graphic memory to be finally displayed. Generate an image.
