Claims

[Scope of claim for utility model registration] A detection device that uses non-contact means to detect embossments formed under pressure on cards such as vinyl chloride.
a light projecting means for irradiating infrared light onto one side of the card; a light receiving means for receiving the infrared light transmitted through the card from the opposite side; and a light receiving means for blocking visible light entering the light receiving means. An emboss detection device comprising: visible light blocking means;
