The movable part 12 is supported in the case 15 so as to be rotatable by interposing a rolling element between the outer peripheral surface of the cylindrical part 16 and the inner peripheral surface of the frame 29, for example. Is done.

  The flange portion 17 of the movable portion 12 has “0”, “1”, “2”, “3”, “4” as the second display design 18b for displaying the engine speed that is the second measurement amount. ”,“ 5 ”,“ 6 ”,“ 7 ”,“ 8 ”,“ 9 ”are arranged in a circular arc around the center. These characters serve as indicators of the engine speed of the vehicle in units of × 1000 r / min. The flange portion 17 excluding the display design 18b or the display design 18b has light transmission, and receives light from the light source 27b arranged on the back side, and shines in the illumination color of the light source 27b. It is like that. In order to further improve the visibility, the illumination colors of the light source 27a and the light source 27b are preferably different from each other. Further, teeth 25 that mesh with a gear 24 of a drive mechanism 21 to be described later are provided on the outer peripheral edge of the flange portion 17, and the movable portion 12 is driven to rotate by the drive mechanism 21.

  The drive mechanism 21 includes a drive device 22 housed in the case 15, a first gear 23 connected to the rotation shaft of the drive device 22, and a first gear 23 that is pivotally supported by the case 15 and meshes with the first gear 23. 2 gears 24. The first gear 23 and the second gear 24 constitute a speed reduction mechanism having a predetermined speed reduction ratio, and the driving unit 22 drives the movable portion 12 of the dial via this speed reduction mechanism. Note that the drive mechanism 21 is covered by the shielding portion 31 of the turning member 13.

  As the driving device 22 and the driving device 20 that drives the pointer 14, for example, a stepping motor or the like that can control the rotation angle in both forward and reverse directions can be used.

FIG. 3 shows a control system of the instrument 10.
The control circuit provided on the wiring board of the combination meter 50 includes a meter control unit 38 and a movable part drive control unit 39. The meter control unit 38 has an engine speed signal output from an engine control unit (ECU) 36 provided in the vehicle according to the engine speed, and a speed sensor 37 provided in the vehicle according to the traveling speed. The travel speed signal output in this way is input.

  The meter control unit 38 indicates the position of the pointer 14 in accordance with the traveling speed of the first display design 18a provided on the fixed portion 11 of the dial based on the input traveling speed signal. , And a pointer driving control signal corresponding to the calculation result is sent to the driving device 20. The meter control unit 38 sends the engine speed signal and the pointer drive control signal to the movable part drive control unit 39.

  The movable portion drive control unit 39 calculates the rotation angle of the pointer 14 from the input pointer drive control signal, and based on the rotation angle of the pointer 14 and the engine speed, the movable portion drive control unit 39 is provided in the movable portion 12 of the dial. The rotation angle of the movable part 12 is calculated so that the position corresponding to the engine speed of the display design 18b of 2 is arranged in the direction indicated by the pointer 14, and the movable part drive control signal corresponding to the calculation result is driven. Send to device 22.

  The driving device 20 drives the pointer 14 based on the input pointer driving control signal. Further, the driving device 22 drives the movable portion 12 based on the input operating portion driving control signal. In the case of using, for example, a DC motor as the driving device 22 and the driving device 20, for example, a DC motor or the like, an arbitrary rotating element (movable portion 12, pointer 14) using a rotation angle sensor such as an encoder is used. , Gears 23, 24, etc.) are detected, and the sensor outputs are fed back to the meter control unit 38 and the movable portion drive control unit 39 to calculate the rotational angles of the pointer 14 and the movable portion 12.

  Next, the operation of the vehicular instrument 10 configured as described above will be described.

  First, in the vehicle stop state, as shown in FIG. 1, the pointer 14 indicates the character “0” of the first display design 18a provided on the fixed portion 11 of the dial, and the dial is movable. The part 12 is in a state where the character “0” of the second display design 18 b is arranged in the direction indicated by the pointer 14.

  As the vehicle travels, as shown in FIG. 4, the driving device 20 drives the pointer 14 based on the input pointer drive control signal, whereby the pointer 14 is rotated to rotate the dial fixing portion 11. A location corresponding to the traveling speed of the first display design 18a provided in the is indicated, and the traveling speed is displayed.

  In synchronism with this, the driving device 22 drives the movable portion 12 of the dial via the gears 23 and 24 based on the input movable portion drive control signal, whereby the movable portion 12 rotates. The location corresponding to the engine speed of the second display design 18b provided in the movable portion 12 is arranged in the direction indicated by the pointer 14, and the engine speed is displayed.

  According to the vehicle instrument 10 of the present embodiment, the pointer 14 is rotated so as to indicate the location corresponding to the traveling speed of the first display design 18a provided on the fixed portion 11 of the dial, and the traveling speed is increased. At the same time, the movable portion 12 is rotated so that a position corresponding to the engine speed of the second display design 18b provided on the movable portion 12 of the dial is arranged in the direction indicated by the rotated pointer 14. The engine speed is displayed. As described above, since a plurality of measured amounts are displayed by the single pointer 14, there is a possibility that a problem may occur in which it is mistaken which display design each pointer indicates when using a plurality of pointers. In addition, the amount of line-of-sight movement can be reduced as compared with the case where a plurality of instruments are independently arranged for each measurement amount, thereby improving visibility. Since a plurality of measured amounts are displayed with a single meter, the occupied space can be reduced as compared with the case where a plurality of meters are arranged independently for each measured amount.
