Abstract: Provided is a printed circuit board having a breakdown detection pattern formed thereon for preventing illicit acquisition of sensitive data, the printed circuit board being configured so that false detection of a disconnection or a short in the breakdown detection pattern can be prevented. The printed circuit board (7) comprises a breakdown detection pattern layer (32) wherein a breakdown detection pattern is formed for detecting a disconnection and/or a shorting thereof, a first pattern layer (31) disposed more to a Y1 direction side than the breakdown detection pattern layer (32), a second pattern layer (33) disposed more to a Y2 direction side than the breakdown detection pattern layer (32), and signal pattern layers (34 to 36) disposed more to the Y2 direction side than the second pattern layer (33). Formed in the first pattern layer (31) are a grounding pattern and a power source pattern covering the breakdown detection pattern from the Y1 direction side. Formed in the second pattern layer (33) are a grounding pattern and a power source pattern covering the breakdown detection pattern from the Y2 direction side.

Abstract: A card processing device may include a moving part having a support member and a presser member, the moving part being structured to move in the thickness direction of the card; a holding member; an abutting member; a first urging member urging the abutting member in the ejecting direction; a second urging member urging the moving part; and a drive source to move the moving part. In inserting the card, the holding member may slide from a hold position to a retreated position, and the moving part may move from an insertable and ejectable position to an insertion completion position. In ejecting the card, the moving part may move from the insertion completion position to the insertable and ejectable position, and the abutting member may push the card in the ejecting direction of the card.

Abstract: A magnetic field generator may include a magnetic field generation part including a resonance part including an inductor and a capacitor connected with each other, and which is structured so that an AC current is flowed between the inductor and the capacitor by charging electric charge to the capacitor and discharging the electric charge to generate a magnetic field by a resonance; a current direction monitoring section structured to monitor a direction of a current flowing through the inductor of the magnetic field generation part; and a judging section structured to control a timing for charging in the magnetic field generation part depending on the direction of the current flowing through the inductor which is obtained by monitoring of the current direction monitoring section.
