  • Patent number: 11829817
    Abstract: A card reader includes a card lock mechanism for preventing pulling-out of a card from an insertion port when the card is jammed in a conveyance passage. The card lock mechanism includes a motor, a lock member driven by the motor to be moved between a contact position and a retreated position, a knob mechanically connected with the motor, and a detection mechanism for detecting the lock member located at the retreated position. The card reader includes a control part which is configured so that, after the motor is driven to move the lock member to the contact position, when the detection mechanism detects that the lock member has moved to the retreated position, the control part executes a tactile stimulation sequence in which the motor is driven to apply movement to the knob so that attention of an operator operating the knob is called in a tactile manner.

  • Patent number: 11791703
    Abstract: The actuator includes a magnetic drive mechanism to relatively move the movable body with respect to the support body. The magnetic drive mechanism has a magnet and a coil. The connecting element connected to the support body and the movable body is a viscoelastic member. The viscoelastic member has a temperature characteristic that a loss tangent (Tan ?) thereof measured by a dynamic viscoelasticity measurement decreases as a temperature rises. When using a silicone gel as the connecting element, the decrease in the peak value of the acceleration of the movable body caused by the decrease in the current flowing through the coil is cancelled by the increase in the peak value of the acceleration of the movable body caused by the decrease in Tan ? of the silicone gel. Therefore, the oscillation of the movable body is unchanged even if a temperature changes.
