JPH0723824Y2 - Digital fare display with display panel illumination - Google Patents

Description

[Detailed Description of the Device] “Industrial Application Field” This device is provided, for example, in a bus vehicle to display a fare corresponding to a numbered ticket number, and particularly to make it easier for passengers to see the numbered ticket number at night. The present invention relates to a digital fare indicator with a display panel illumination.

"Prior art" In the digital fare display, a frame is printed on the display panel to form an array of fare sections consisting of the numbered ticket number printing section and the fare display transparent section, and the numbered ticket number is printed on each numbered ticket number printing section. Is printed, and the number display light emitting element is arranged behind each fare display transparent portion to display the fare.

In this type of digital fare indicator, the numbered ticket number becomes difficult to see at night, so an illumination lamp was attached to the outside to illuminate the numbered ticket number. However, this external lighting makes the display panel surface too bright, making it difficult to see the fare display area.

[Means for Solving the Problems] According to the present invention, the panel holding and end face blocking plates are respectively contacted with the three end faces of the display panel, and the display panel is held by the frame body by these panel holding and end face blocking plates. To be done. A fluorescent lamp is arranged so as to face an end surface of the display panel on which the panel pressing / end surface blocking plate is not provided. Further, the numbered ticket number is printed on each of the numbered ticket number printing portions of the display panel with the fluorescent paint containing glass beads.

"Operation" Light from a fluorescent lamp enters the display panel, and relatively uniform surface illumination is performed. The light emitted from this display panel is scattered by the glass beads in the paint of the ticket number, and the scattered paint stimulates the fluorescent paint to make the ticket number shine.

[Example] As shown in FIGS. 1 and 2, the front plate of the box 11 is a rectangular frame 12, and a display panel 13 made of a transparent acrylic plate is provided in the frame 12 so as to cover the frame 12. Incorporated. Display panel
End face blocking plate that also serves as a panel retainer on each of the upper, left, and right end faces 14
Are opposed to each other, and the display panel 13 is held by the frame body 12 by the panel pressing / end face blocking plate 14. The lower end surface of the display panel 13 is closely faced and a fluorescent lamp 15 is arranged along the lower end surface. The rear side of the fluorescent lamp 15 is a fluorescent lamp guide plate
Covered with 16. Below the fluorescent lamp 15, an inverter 17 for lighting the fluorescent lamp is arranged.

As shown in FIGS. 1 and 3, a frame line 18 is printed on the display panel 13 to form an array of fare sections including a numbered ticket number printing section 19 and a fare display transparent section 21. Numbered ticket number printing department
A numbered ticket number 22 is printed on 19 and the background of the numbered ticket number 22 is opaquely printed. A number display light emitting element 23 for displaying the fare is arranged behind the fare display transparent portion 21 so that the display of the number display light emitting element 23 can be seen from the outside.

Numbered ticket number 22 is printed with fluorescent paint with glass beads. For example, as shown in FIG. 4 (a), a numbered ticket number printing section
Opaque printing is performed on 19 so that the numbered ticket number 22 is a transparent character. Next, as shown in FIG. 4 (b), a numbered ticket number 22
Perform surface printing on. As the paint for surface printing, for example, a mixture of 70% organic solvent and 30% glass bead paint is used. Next, as shown in FIG. 4 (c), a numbered ticket number 22
Fluorescently print on. As the paint for the fluorescent printing, for example, a mixture of 60% organic solvent and 40% fluorescent paint is used. Finally, the numbered ticket number 22 is printed in white as shown in FIG. 4 (d). This printing makes numbered ticket number 22 brighter.

When the fluorescent lamp 15 is turned on, the light of the fluorescent lamp 15 enters the display panel 13 from its lower end surface and illuminates the entire surface of the display panel 13. The light entering the numbered ticket number 22 from the display panel 13 is scattered by the glass beads of the paint, and the scattered light stimulates the fluorescent paint so that the numbered ticket number 22 shines.

[Effect of device] As described above, according to this device, the numbered ticket number is printed at night with a simple structure in which the fluorescent lamp is placed along the edge of the display panel and the numbered ticket number is printed with the fluorescent paint containing glass beads. Is easy to see, and there is no fear that the fare display will be difficult to see.
