Abstract
The platen gap adjustment mechanism 70 of a printer 1 adjusts a gap between a printhead 59 and a platen 25 by moving first and second guide rails 57, 58 that support the head carriage 59 in a gap adjustment direction relative to the platen 25. A rotary mechanism for synchronously rotating the first and second guide rails 57, 58 to adjust the gap has a rotary shaft 101 perpendicular to the first and second guide rails 57, 58; first and second drive-side gears (e.g. worms) 104, 105 disposed coaxially to the rotary shaft 101; a first driven-side gear (e.g. worm wheel) 106 disposed coaxially to the first guide rail 57 and meshing with the first drive-side gear 104; and a second driven-side gear (e.g. worm wheel) 107 disposed coaxially to the second guide rail 58 and meshing with the second drive-side gear 105.
