Identification apparatus

摘要

An apparatus body is provided with a sensor face in which a plurality of sensor electrodes for detecting electrostatic capacitance are disposed. A recognition pattern formed by connecting a plurality of conductive spots through conductive lines is provided in an identification body. When the recognition pattern of the identification body is made to face the sensor face of the apparatus body, the plurality of sensor electrodes are electrically connected to one another through the recognition pattern to thereby generate a change of electrostatic capacitance so that the apparatus body can identify the recognition pattern based on the change of electrostatic capacitance. Thus, it is possible to provide an identification apparatus which can be manufactured inexpensively without use of an expensive apparatus such as an RFID system.

1. An identification apparatus comprising:
an identification body such as a top or a card; and an apparatus body for identifying an ID of the identification body; wherein:
the apparatus body has a sensor face in which a plurality of sensor electrodes for detecting a change of electrostatic capacitance are disposed;a recognition pattern formed by connecting a plurality of conductive spots through conductive lines is provided in the identification body;the conductive spots are allocated in a one-to-one correspondence with the sensor electrodes; andthe recognition pattern of the identification body is made to face the sensor face of the apparatus body so that the plurality of sensor electrodes can be electrically connected to one another through the recognition pattern to thereby generate a change of electrostatic capacitance that is produced through only contact between the identification body and the apparatus body such that the apparatus body identifies the recognition pattern based on the change of electrostatic capacitance.
