Patent number: 11654704Abstract: A printer includes a gap adjustment unit that displaces a carriage in a Z-axis direction in which a gap changes. The gap adjustment unit has a sliding member that moves in a width direction integrally with the carriage, and a cam member that is interposed between the carriage and the sliding member and has a stepped portion in which a maintenance surface that maintains a position of the carriage in the Z-axis direction and an adjustment surface that changes the position of the carriage in the Z-axis direction are alternately arranged in the width direction. The gap adjustment unit is configured such that the cam member slides in the width direction with respect to the carriage and the sliding member to change the gap. The gap adjustment unit includes a buffer unit that decreases a displacement speed of the carriage in the Z-axis direction when the gap is reduced.Type: GrantFiled: October 6, 2021Date of Patent: May 23, 2023Assignee: Seiko Epson CorporationInventors: Keita Hanawa, Katsunari Kumagai, Kensuke Tamai
