Patent number: 8061804Abstract: A method of moving a cap apart from a printhead within a short period of time without damaging a printing apparatus when the cap sticks to the printhead. A cap moving unit is driven to try to move the cap apart from the printhead. When a detection unit for detecting that the cap has moved apart from the printhead detects that the cap has not moved apart from the printhead, it is controlled to slightly reciprocate the carriage while driving the cap moving unit. When the detection unit detects that the cap has moved apart from the printhead under this control, the slight reciprocation of the carriage is forcibly stopped.Type: GrantFiled: December 11, 2008Date of Patent: November 22, 2011Assignee: Canon Kabushiki KaishaInventors: Atsushi Shimizu, Masaaki Matsuura, Tsuyoshi Otani, Ken Hoshino

Patent number: 7584951Abstract: A conveying device which can determine whether an error occurred therein. When a transmission unit is in a transmission state, a sheet feed roller is driven by a DC motor to perform first driving for conveying a sheet up to a conveying roller. The occurrence of an error with respect to the sheet feed roller is determined based on information obtained from an encoder during the first driving. When the occurrence of an error is determined, second driving is performed. A conveyance error is determined based on a count value during the first driving and a count value during the second driving, which are both obtained from the encoder.Type: GrantFiled: June 27, 2007Date of Patent: September 8, 2009Assignee: Canon Kabushiki KaishaInventors: Tsuyoshi Otani, Hiroyuki Kakishima, Shinya Sonoda

Patent number: 7344224Abstract: A carriage, on which a recording head is mounted, and to which a moving unit is connected, reciprocates a recording area by the moving unit to perform recording by the recording head. In the carriage, a recording head mount part and a connection part to the moving unit are separately provided, and the mount part and the connection part are coupled by a coupling structure having a linear elastic member. Hereby, vibration from the moving unit is shielded in the division portion and is not transmitted to the recording head mount part. Therefore, recording accuracy of the recording head can be kept in a high state.Type: GrantFiled: January 27, 2005Date of Patent: March 18, 2008Assignee: Seiko Epson CorporationInventors: Takayuki Ishii, Kazumi Kamoi, Tsuyoshi Otani
