Patent number: 11710004Abstract: A card reader includes a card conveyance path comprising upper and a lower conveyance paths to convey a card inserted into a device; and a reading unit that reads information on the card. Lower concave and convex portions are provided on an upper surface of the lower conveyance path behind the reading unit. Upper concave and convex portions are provided on a lower surface of the upper conveyance path to be fitted to the lower concave and convex portion. A pressing unit provides a fitted state of the lower and upper concave and convex portions when no object is present. A detection sensor detects a state where an interval between the lower and upper concave and convex portions is widened. The detection sensor detects the state where the interval is widened, to recognize that an object is inserted between the lower and upper concave and convex portions.Type: GrantFiled: February 1, 2022Date of Patent: July 25, 2023Assignee: HITACHI CHANNEL SOLUTIONS, CORP.Inventor: Takeshi Kageyama

Patent number: 7872554Abstract: A pulser ring and a second seal ring are separately formed. When a multipolar magnetic rotor of the pulser ring is bonded to an outer circumferential face of an outer cylindrical portion of an annular core portion, the multipolar magnetic rotor is opposed to a magnetic sensor in the radial direction. Due to the above structure, the multipolar magnetic rotor can be strongly supported by an outer cylindrical portion of the annular core portion. Therefore, even when a rotary centrifugal force is given to the multipolar magnetic rotor, it can not be swung in the radial direction. Accordingly, an interval of the multipolar magnetic rotor and the magnetic sensor in the radial direction, which are opposed to each other, can be maintained constant irrespective of an intensity of the centrifugal force.Type: GrantFiled: November 23, 2007Date of Patent: January 18, 2011Assignees: JTEKT Corporation, Uchiyama Manufacturing Corp.Inventors: Takeshi Kageyama, Katsura Koyagi, Masahiro Inoue
