MEDIUM PROCESSING APPARATUS

摘要

A medium processing apparatus may include a medium conveying passage; a thermal head; a head holding part; and a moving mechanism structured to move the thermal head and the head holding part between a contact position and a retreated position. The head holding part may include a head holding member; a head support shaft structured to support the thermal head; and a pressing mechanism structured to press the thermal head toward the head holding member in the conveyance direction of the medium.

主权项

1. A medium processing apparatus for use with a medium in a card shape, the medium processing apparatus comprising:
a medium conveying passage where the medium is conveyed; a thermal head which is structured to contact with the medium passing the medium conveying passage and perform printing; a head holding part structured to hold the thermal head; and a moving mechanism structured to move the thermal head and the head holding part between a contact position where the thermal head contacts the medium and a retreated position where the thermal head is retreated from the medium conveying passage; wherein the head holding part comprises:
a head holding member;a head support shaft structured to support the thermal head so that the thermal head turns with respect to the head holding member with a conveyance direction of the medium when the thermal head and the head holding part are located at the contact position as an axial direction of turning; anda pressing mechanism structured to press the thermal head toward the head holding member in the conveyance direction of the medium when the thermal head and the head holding part are located at the contact position.
