  • Patent number: 10204242
    Abstract: Provided is a card insertion and ejection mechanism to be mounted forward of a card reader structured to convey a card so that a longitudinal direction of the card is coincided with a conveying direction of the card, the card insertion and ejection mechanism being capable of preventing skimming and capable of sending into the card reader the card in an orientation capable of being processed by the card reader even when the card is inserted into the card insertion and ejection mechanism in any orientation. A card insertion and ejection mechanism takes in a card to a turning position when the card is inserted into a card insertion port with front and rear sides of the card directed correctly so that a short widthwise direction of the card is coincided with an “X” direction, and controls a card turning and conveying mechanism in a turning direction and at a turning angle based on a result of determination as to an orientation of the inserted card, to turn the card.

  • Patent number: 9767391
    Abstract: A card reader may include a card conveying mechanism; a guide; a magnetic head; a positioning member to position the card relative to the magnetic head; and a shutter. The positioning member may include a card abutting part to abut a third direction end of the card; and a card support part to contact a first direction side of the card. A distance between the card abutting part and a third direction end of the guide is shorter than a width in the short-side direction of the card. When the shutter has closed, a fourth direction end of the shutter is disposed on a first direction side of the guide. When the shutter has opened the opening, the shutter is disposed on the first direction side of the guide. The third direction end of the card may be guided to the card support part by the shutter.
