Even if a light emitter 631 composed of a point light source such as a chip-type LED is used, unevenness in light emission of the display board 61 can be suppressed, and the display drawn on the display board 61 can be clearly seen. The

  The display board 61 is made of a transparent synthetic resin board, preferably a transparent acrylic board. Regarding the display of the display board 61, the display 611 of the method of using the electric vehicle power supply device P has four levels. In the lower part of the screen, a “currently supplied power” display 612 is displayed, and a “powering” display 613, a “failing” display 614, and a “power supply completed” display 615 are displayed in parallel below the display 612. In the bottom row, a sheet on which a display 616 of “Power cannot be supplied when this lamp is off” is attached to the surface of a transparent acrylic plate. In addition, the sheet is cut out to the size of the LED 621 that displays the 7-segment display next to the “currently supplied power amount” display 612. Therefore, when the 7-segment display is turned on, a display showing the amount of power supply appears through the transparent display board 61.

  In addition, on the light emitting board 63 located on the back side of the indications 613 to 615 of “power feeding”, “failing” and “power feeding completed” in parallel with the display board 61, orange, red, A plurality of light emitters 631 that emit green light are mounted, and are partitioned from each other by a partition plate 66 attached to the light emitting substrate 63 so that the respective displays have different colors. Similar to the LED 621 for displaying the 7-segment display, the partition plate 66 is also projected to the vicinity of the display plate 61, so that the light emitters 631 of different colors interfere with each other and the color is not mixed, so that it is clear. The power supply status can be identified by color. In addition, as described above, the light emitting substrate 63 on which a plurality of chip LEDs as the light emitters 631 are mounted is provided on the back side of the display board 61, and the chip LEDs emit white light, The entire display board 61 (the LED 621 that displays the 7-segment display and the portions other than the “power supply”, “failing”, and “power supply completion” displays 613 to 615) emits white light.

  The frame member 64 of the display device 6 is attached to the back surface of the surface portion 41 of the upper door 4a of the electric vehicle power supply device P by being fastened with a screw that attaches the surface portion 41 to the upper door 4a. The electric vehicle power supply device P used is configured. Note that a polycarbonate plate is preferably used as the surface portion 41 so as to protect the display plate 61 of the display device 6 located on the back surface thereof.

  As described above, the display of the display board 61 is configured by pasting a sheet on which the display contents are described or cut out on the front or back surface of the display board 61 made of a transparent acrylic plate. The display content may be formed by applying printing such as silk screen printing on the front or back surface of the display plate made of a transparent acrylic plate, and the display formation method is not particularly limited. Any method can be adopted.

  In addition, as shown in FIG. 12, a cover 67 may be attached to the LED 621 that displays a 7-segment display attached to the display substrate 62 so as to cover the periphery thereof. By doing so, when the LED 621 for displaying the 7-segment display is turned on, the influence of white light emitted from the light emitter 631 of the light-emitting substrate 63 is suppressed, and the 7-segment display is displayed through the display board 61. The display of the LED 621 can be read clearly. The material of the cover 67 is not particularly limited, but rubber or thermoplastic elastomer, which is a material that hardly damages the back surface of the display plate 61 even when the cover 67 contacts the back surface of the display plate 61, is used. In particular, black chloroprene rubber is preferably used. By using the black chloroprene rubber, the LED 621 for displaying the 7-segment display is outlined in black, so that the display becomes more conspicuous and easy to read.

  Note that white light emitted from the light emitter 631 of the light-emitting substrate 63 enters from the gap between the rear surface of the display board 61 and the front surface of the LED 621 that displays the 7-segment display, and the display of the LED 621 that displays the 7-segment display is difficult to see. In this case, it is preferable to substantially eliminate the gap between the rear surface of the display board 61 and the front surface of the LED 621 that displays the 7-segment display, and attach the cover 67 so as to cover the periphery of the LED 621 that displays the 7-segment display. When there is almost no influence of the white light emitted from the light emitter 631 of the substrate 63, the 7-segment display is displayed so that the front surface of the LED 621 for displaying the 7-segment display is flush with the front surface of the cover 67. A cover 67 may be attached around the LED 621 to be made. Moreover, the cover 67 is attached so that the said chloroprene rubber | gum etc. may be shape | molded in a short cylindrical body, and it may be externally fitted to LED621 which makes 7 segment display appear.
