Publication number: 20230067797Abstract: A printing apparatus includes: a roll sheet container that contains a roll sheet around which a recording sheet is wound; a first sheet guide that makes contact with a first surface of the recording sheet; a second sheet guide that makes contact with a second surface of the recording sheet; and a transport roller that transports the recording sheet. The first and second sheet guides are disposed so as to face each other to form a sheet route along which the recording sheet is to pass. The transport roller transports the recording sheet that passed along the sheet route. The second sheet guide includes: a projection that protrudes toward the roll sheet container; and a pushing section that extends from the projection along an outer circumference of the roll sheet and in a direction away from the first sheet guide.Type: ApplicationFiled: November 8, 2022Publication date: March 2, 2023Inventors: Takeshi TOKUDA, Rikuo YAMADA, Takehiro KOBAYASHI, Hideaki NISHIJIMA

Patent number: 9731524Abstract: A cutter blade moving mechanism moves a cutter blade to a forward position by a low output drive motor without an urging member urging the cutter blade to the forward position where media is cut. The first cutter blade moving mechanism has a drive gear that moves the first cutter blade forward and back; a drive motor; and a compound gear to which rotation of the drive motor is transferred. The intermittent teeth part of the compound gear meshes with a transfer gear after turning the compound gear is started by drive power from the drive motor, completing a rotation transfer path. Because there is a delay between when driving the drive motor starts and when the path transferring rotation from the drive motor to the drive gear is completed, rotational kinetic energy is stored in the compound gear during this delay. The transfer gear can therefore be turned with greater drive power (rotational kinetic energy) when the compound gear and transfer gear mesh.Type: GrantFiled: January 5, 2016Date of Patent: August 15, 2017Assignee: SEIKO EPSON CORPORATIONInventors: Hideaki Nishijima, Tetsugo Ishida, Hiroshi Narita, Rikuo Yamada

Patent number: 9522552Abstract: A cutter has a first cutter blade moving mechanism 24 that moves a first cutter blade 21 reciprocally between a forward position 21A where recording paper 3 is cut and a retracted position 21B separated from the forward position 21A; and a second cutter blade moving mechanism 25 that moves a second-cutter blade 22 between a contact position 22A where the paper is cut in contact with the first-cutter blade 21 and a release position 22B separated from the contact position. The second cutter blade moving mechanism 25 sets the second cutter blade 22 to the release position 22B before the first cutter blade moving mechanism 24 moves the first cutter blade 21 from the forward position 21A to the retracted position 21B. Wear and noise can be prevented because the two cutter blades 21, 22 do not contact after cutting the recording paper 3.Type: GrantFiled: December 14, 2015Date of Patent: December 20, 2016Assignee: Seiko Epson CorporationInventors: Tetsugo Ishida, Hideaki Nishijima
