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

Patent number: 11420457Abstract: An apparatus includes a gap adjuster that adjusts a gap in a vertical direction between a recording head and a supporting surface for supporting a medium. The gap adjuster adjusts the gap by engagement of a carriage, a slide member, and a cam member that is provided therebetween and has a stepped portion with an alternate-arrangement structure in a width direction. The gap adjuster includes a coil spring that urges the carriage with respect to the slide member in the direction that is the opposite of the transportation direction. A slide contact member is provided on an end of the coil spring.Type: GrantFiled: April 7, 2021Date of Patent: August 23, 2022Assignee: Seiko Epson CorporationInventors: Keita Hanawa, Kensuke Tamai, Katsumi Yamada, Tatsuya Ito
