Printing apparatus

A printing apparatus comprising:

• a printer body unit;
• an opening and closing unit provided on the printer body unit and having an open state in which a front-face side of the opening and closing unit is opened with respect to the printer body unit by a hinge provided on a back-face side of the printing apparatus and a closed state in which the front-face side of the opening and closing unit is closed with respect to the printer body by the hinge;
• a first gear member provided in the printer body unit;
• and
• a second gear member provided with a plurality of teeth along a longitudinal direction of the second gear member, the second gear member meshing with the first gear,
• wherein, in the longitudinal direction of the second gear member, one end of the second gear member is an attachment end and the other end of the second gear member is a distal end, the attachment end being attached to the opening and closing unit, the second gear member being configured to swing about the attachment end, and
• wherein the distal end of the second gear member is configured to swing to the front-face side in a case where the opening and closing unit moves from the open state to the closed state such that an angle between the distal end of the second gear member and a lower face of the opening and closing unit in the closed state is smaller than an angle between the second gear member and a lower face of the opening and closing unit in the open state.

• a second gear member provided with a plurality of teeth along a longitudinal direction of the second gear member, the second gear member meshing with the first gear member;
• a guide part provided on the printer body unit and having a shaft shape;
• and
• an engagement part provided on the second gear member and having a groove shape which is movably engaged to the guide part,
• wherein, in the longitudinal direction of the second gear member, one end of the second gear member is an attachment end and the other end of the second gear member is a distal end, the attachment end being attached to the opening and closing unit, the second gear member being configured to swing about the attachment end, and
• wherein a distance between the distal end of the second gear member and a lower face of the opening and closing unit, in a case where the opening and closing unit is in a closed state, is shorter than a distance between the distal end of the opening and closing unit and the lower face of the opening and closing unit in a case where the opening and closing unit is in an open state.
