Memorial Stone QR Code Plate

Abstract

This memorial stone QR code plate reduces the effects of surface reflection unique to black granite, improving the visibility and readability of QR codes (registered trademark). [Solution] The memorial stone QR code plate of this invention has a QR code laser-engraved onto a black granite plate, and a colored layer is formed on the engraved area to suppress light reflection and improve contrast. The plate is supported by a base at an angle of approximately 45 to 75 degrees with respect to the vertical direction. The structure of this invention, which combines the plate and base, can be easily applied to a variety of installation environments such as indoor displays, cemeteries, and memorial spaces.

[0001] The present invention relates to a commemorative stone plate, particularly to a plate made of black granite with a QR code engraved thereon, suppressing the reflection of the engraved part, and improving the reading stability of the QR code by means of an inclined installation structure with a pedestal.

Background Art

[0002] Conventionally, a technology of engraving a QR code on a stone material such as a tombstone or a monument to provide information such as an image or a video has been known. However, black granite has strong gloss and reflection on its surface, and there is a problem that even when a QR code is engraved, the reading may become unstable depending on the light reflection conditions.

Summary of the Invention

Problems to be Solved by the Invention

[0003] An object of the present invention is to provide a memorial stone QR code plate that reduces the influence of light reflection on the QR code engraved on the surface of black granite and can be stably read in various installation environments indoors and outdoors.

Means for Solving the Problems

[0004] The present invention laser-engraves a QR code on a plate made of black granite, forms a coloring layer that suppresses light reflection and improves contrast on the engraved part, and has a structure in which the plate is supported by a pedestal at an angle of about 45 degrees to about 75 degrees with respect to the vertical direction. Thereby, it suppresses the incident of the reflected light on the stone surface directly onto the imaging surface, and improves the visibility and reading stability of the QR code.

Effects of the Invention

[0005] According to the present invention, the following effects can be obtained. (1) The colored layer formed on the engraved area suppresses the reflection characteristic of black granite, improving the contrast of the QR code. (2) By setting the plate at an angle of approximately 45 to 75 degrees relative to the vertical, reflections during shooting can be avoided, and QR code reading by smartphones, etc., can be made more stable. (3) Because it has a structure that combines a plate and a base, it can be easily adapted to a variety of installation environments such as burial sites, indoor exhibitions, and memorial spaces.
