Title:
RADIO DATA CARRIER RECOGNITION DEVICE
Document Type and Number:
Japanese Patent JP3854248
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To extend a recognition area of a radio data carrier without moving an irradiation direction of an antenna.
SOLUTION: A radio data carrier recognition device is provided with the antenna 3 for irradiating the prescribed recognition area 5 in which the radio data carrier is considered to position with an inquiry radio wave and a reflecting plate 4 arranged in a position confronted with an antenna face of the antenna 3. The reflecting plate 4 has a convex reflecting face which reflects the inquiry radio wave irradiated from the antenna 3 and extends an irradiation area of the inquiry radio wave much more than the recognition area.
