<p>The present invention provides a printer with which both position adjustment and attachment/detachment of a printing head can be performed easily. The printer includes: a platen roller; a printing head; a first head support member capable of rotating relative to a casing; a first shaft serving as a rotary axis of the first head support member; a second shaft that is attached to the first head support member and includes a large diameter portion and a small diameter portion having a different central axis to the rotary axis; and a second head support member, to which the printing head is attached, and which is formed with a first set of grooves into which the first shaft is inserted and a second set of grooves into which the second shaft is inserted, moves in accordance with rotation of the second shaft, when attached to the first head support member, due to engagement between the first set of grooves and the first shaft and engagement between the second set of grooves and the small diameter portion of the second shaft, and can be removed from the first head support member by moving the second shaft parallel to the axial direction.</p> |
