  • 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: 10083327
    Abstract: A card reader may include a magnetic sensor to detect whether magnetic data are recorded in the magnetic stripe of the card; a control section to supply electric power to the magnetic sensor and into which an output signal of the magnetic sensor is inputted; and a card insertion port into which the card is inserted and in which the magnetic sensor is disposed. The magnetic sensor may output an output signal when the electric power is supplied from the control section. The control section may supply the electric power to the magnetic sensor during a first supply time period which is shorter than a card passage time period.

  • Patent number: 9707614
    Abstract: Through a tube expanding processing simulation, a workpiece shape in a state where a tip of a workpiece 10 has advanced by 1.0 m or more after passing through a shoulder portion 3 of a tool 1 is evaluated. A hollow piece shape and a tool shape such that the external diameter is within ±1% of the target, the thickness is within ±7.5% of the target, and the internal gap between the hollow piece and the tool is 1.0 mm or less are obtained by repeated calculation, and thereby actual tube expanding manufacturing conditions are determined.
