摘要
It is an object of the present invention to provide a small thin integrated antenna type non-contact IC card reader/writer, the characteristic of which is stable, characterized in that: the device is seldom affected by the restriction of a place in which the device is installed; the device is seldom affected even when the coaxial cable is laid round the device; and it is unnecessary to adjust the resonance frequency of the antenna, so that the device can be easily installed.;An integrated antenna type non-contact IC card reader/writer of the invention comprises: a loop antenna (1) for supplying electric power and sending data to a non-contact IC card (102) by electromagnetic induction and for acquiring receiving data from the non-contact IC card by a change in the load; a control portion (4) for controlling a resonance matching circuit, wireless sending portion (2) and wireless receiving portion (3); and a control board on which the control portion is mounted, the control board (5) being accommodated in a shielded case (6), wherein the components are arranged and assembled so that a central axis of the loop antenna in the thickness direction and a central axis of the shielded case in the thickness direction can be made to substantially coincide with each other.
