Card reader and control method therefor

A card reader comprising:

• an insertion port where a card is inserted and ejected;
• a conveyance passage where the card inserted from the insertion port is conveyed;
• and
• a card lock mechanism structured to prevent pulling-out of the card from the insertion port when the card is jammed in the conveyance passage;
• wherein the card lock mechanism comprises:
• a motor;
• a lock member which is provided with a blocking pawl structured to contact with the card and prevent pulling-out of the card and is driven by the motor to be moved between a contact position where the blocking pawl is contacted with the card and a retreated position where the blocking pawl is retreated from the conveyance passage;
• a knob mechanically connected with an output shaft of the motor;
• and
• a detection mechanism structured to detect the lock member located at the retreated position;
• wherein the card reader comprises a control part which controls a position of the lock member by driving the motor;
• and
• wherein the control part is configured so that, after the control part performs first control in which 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.
