Patent number: 11951735Abstract: A printing device includes: a printing unit printing on a recording paper; a feeder unit having a roller that rotates about a shaft and feeds the recording paper and a motor that rotates the shaft; a detection unit detecting the rotation of the shaft; and a control unit controlling the printing unit. The control unit calculates an electrifying time during which the printing unit is electrified and a non-electrifying time during which the printing unit is not electrified following the electrifying time, based on a detection signal from the detection unit. When the calculated non-electrifying time is less than a predetermined time, the control unit corrects the non-electrifying time in such a way that the non-electrifying time becomes equal to or longer than the predetermined time, and causes the printing unit to print.Type: GrantFiled: November 18, 2021Date of Patent: April 9, 2024Assignee: SEIKO EPSON CORPORATIONInventors: Hitoshi Ishino, Takehiro Kobayashi, Masanori Yumoto

Patent number: 11845267Abstract: A printing device includes: a printing unit printing on a recording paper; a feeder unit that has a roller rotating in a first direction about a shaft and feeding the recording paper, and a motor rotating the shaft; a detection unit detecting a rotation of the shaft in the first direction and a rotation thereof in a second direction opposite to the first direction; and a control unit controlling the feeder unit, based on the rotation of the shaft detected by the detection unit. The control unit causes the motor of the feeder unit to rotate the shaft in the first direction and then stop the shaft, and subsequently causes the motor to rotate the shaft in the first direction before the printing unit prints, based on the rotation of the shaft in the second direction detected by the detection unit.Type: GrantFiled: November 5, 2021Date of Patent: December 19, 2023Assignee: SEIKO EPSON CORPORATIONInventors: Takehiro Kobayashi, Hitoshi Ishino, Rikuo Yamada

Patent number: 9399357Abstract: The temperature of heat elements of a thermal head can be controlled with high precision by a process with a low processor load. A printer 100 that prints on thermal roll paper 102 based on print data has a thermal head 134 with multiple heat elements 136 arrayed in a sub-scanning direction CR perpendicular to the conveyance direction F of the thermal roll paper 102. The printer 100 has a current control unit 112 that segments the heat elements of the thermal head 134 into plural blocks, and controls the energize timing of the heat elements in each block based on the number of heat elements 136 that are energized in the thermal head 134.Type: GrantFiled: July 2, 2015Date of Patent: July 26, 2016Assignee: Seiko Epson CorporationInventors: Hitoshi Ishino, Hideki Furihata

Patent number: 8638351Abstract: A thermal printer having a thermal head with a heat element that heats a recording medium and forms a print dot by energizing the heat element generates a first energizing pulse that energizes continuously during a first period for forming a print dot when the recording medium conveyance speed is greater than a specific threshold value; and generates a second energizing pulse that alternates during the first period between energizing for a second period that is shorter than the first period and de-energizing for a third period when the recording medium conveyance speed is less than or equal to the threshold value.Type: GrantFiled: October 26, 2010Date of Patent: January 28, 2014Assignee: Seiko Epson CorporationInventors: Koji Yamada, Hitoshi Ishino

Patent number: 8139093Abstract: A thermal printer enables both duplex printing and simplex printing. A double-sided thermal printer 1 has a first arm 31 and a second arm 32 that opens and closes in conjunction with the first arm 31. A first platen roller 21 is mounted on the first arm 31, a second thermal print head 12 is mounted on the second arm 32, and a first thermal print head 11 and second platen roller 22 are disposed on the printer frame 30 side. When the operating cover 3 closes, the second thermal print head 12 on the second arm 32 is pressed against the second platen roller 22, the first platen roller 21 on the first arm 31 is pressed to the first thermal print head 11, and the double-sided thermal paper 6 can be set with no slack. For simplex printing, the paper transportation load can be reduced by pressing only the first platen roller 21 on the first arm to the first thermal print head 11.Type: GrantFiled: September 24, 2008Date of Patent: March 20, 2012Assignee: Seiko Epson CorporationInventors: Akira Koyabu, Toru Takami, Sadao Murata, Hitoshi Ishino
