Is mounted on the mounting portion 32 of the holder receiver 15, and the second light source 24 is held by the holder receiver 15. Then, the collar portion 34 of the holder receiver 15 holding the second light source 24 is placed on the tip mounting portion 22. At this time, it is desirable that the holder receiver 15 is not easily detached from the tip mounting portion 22 (for example, press fitting). Similarly, it is desirable that the second light source 24 is not easily detached from the holder receiver 15. Next, the socket 25 is moved along the lead wire 19 toward the second light source 24, and the socket 25 is inserted into the insertion hole 23 to be engaged with the bottom wall 20. Thereafter, the display board 7 is assembled. After the display panel 7 is assembled, at least the tip of the light emitting diode 26 protrudes from the hole 36.

  In such an instrument, if the display device has different display contents such as the operating state of the vehicle or abnormal contents, and if it is desired to exchange the positions of the transmissive display by the lamp 17 and the direct display by the light emitting diode 26, or both When it is desired to display both the display directly by the light emitting diode 26 or when both displays are to be transmissive display by the lamp 17, as described above, the first lamp chamber 13 and the second lamp chamber 16, Each insertion hole 23 has the same shape, the outer diameter shape of the translucent member 12 and the holder receiver 15 accommodated in each lamp chamber 13 and 16, and the outer dimensions and outer diameter shapes of the first holder 18 and the socket 25. Since they are the same, each can be exchanged as a set.

  In this way, even in the case of changing the display form to a different display form in the display device that performs both the transmissive display by the light source and the direct display by the light source, the position of the hole 36 and the display contents are different. It is only necessary to prepare a display board, and there is no need to change the casing 4.

  Further, since the second light source 24 and the socket 25 are connected by the lead wire 19 and the socket 25 is movable along the lead wire 19, the light source mounting body 14 is placed in the second lamp chamber 16. Workability at the time of storage is good, and there is no possibility that an extra lead wire 19 remains (drawn) or is stretched in the second lamp chamber 16. Further, by providing the holder receiver 15 with the slit 33 through which only the lead wire 19 passes, the second light source 24 is held by the holder receiver 15 even if the second light source 24 and the socket 25 are connected by the lead wire 19. be able to.

  Further, the display plate 7 is disposed in front of the first lamp chamber 13 and the second lamp chamber 16, and the light transmitting member 37 is provided on the display plate 7 corresponding to the light transmitting member 12. Even if the display plate 7 is disposed on the member 12, the illumination light transmitted through the light transmitting member 12 can be recognized. In addition, since the hole 36 is provided corresponding to the light emitting diode 26, at least the tip of the light emitting diode 26 protrudes from the hole 36, and the display 38A is provided at the hole 36 (near the light emitting diode 26). The light emission of the light emitting diode 26 can be easily confirmed, and the meaning of the light emission can be understood easily even if the display portion corresponding to the light emitting diode 26 cannot be provided directly on the light emitting diode 26.

  The present invention is not limited to the above-described embodiment. For example, the first light emitter is the lamp 17 and the second light emitter is the light emitting diode 26, but the first light emitter is the light emitting diode. The second light emitter may be a small lamp. In addition, the fact that the first light source and translucent member, the light source mounting body, and the holder receiver in the present invention are provided so as to be replaceable means that they are interchangeable in terms of shape. Therefore, the light emission color of the light emitting diode 26 and the color tone of the translucent member 12 are arbitrary, and even when changing to a different display form, the color tone before and after replacement does not need to match.

  In addition, by providing a transmissive portion 37 at seven locations on the display plate corresponding to the transmissive member 12, the illumination light transmitted through the transmissive member 12 can be recognized. It is good as a part. Alternatively, it may be a frame-like member that covers the peripheral edge of the translucent member 12, the collar portion 34 of the holder receiver 15, and the like without using the display plate provided with the display portion. When the opening is used or when the display plate is not used, the display unit 38 may not be provided or may be provided on the translucent member 12.

  In the present invention, the first lamp chamber 13 refers to a lamp chamber in which the first light source 11 and the translucent member 12 are accommodated, and the second lamp chamber 16 refers to the light source assembly 14 and the holder receiver 15.
