Patent number: 7775614Abstract: The present invention provides complementary recording in that when a defective nozzle is generated, recording is performed by other normal nozzles. According to the present invention, a mask pattern used for multipath recording, which completes an image by multiple scannings with a recording head, is rewritten when a defective nozzle is generated. Rewriting mask data is produced in a CPU register, and the mask pattern is rewritten by repeating the produced mask data. According to the present invention, it is not necessary to prepare mask data by assuming a defective nozzle in advance, so that high speed complementary recording processing can be performed with simple configuration.Type: GrantFiled: April 11, 2005Date of Patent: August 17, 2010Assignee: Canon Kabushiki KaishaInventors: Mitsuharu Takizawa, Tatsuya Fukushima

Patent number: 6721060Abstract: A recording medium cutter capable of moving between two positions, a cutting position and a non-cutting position, in a short time, and also capable of cutting a recording medium at accurate positions. A main body (40) rotatably holding a rotary blade (32) and a driven blade (34) is located between side plates (36 and 38) of the cutter (30). A main shaft (39) serving as the center shaft of the rotary blade (32) is rotatably secured to the side plates (36 and 38). The main shaft (39) also serves as the rotating shaft of the main body (40). A driving motor is secured to the mounting plate (42) of the side plate (36). When the main shaft (39) is rotated by the driving motor (44), the rotary blade (32) rotates. Because the driven blade (34) is pressed against the side face of the rotary blade (32), as the rotary blade (32) rotates, the driven blade (34) revolves around the main shaft (39). As a result, the main body (40) also rotates around the main shaft (39).Type: GrantFiled: September 23, 1999Date of Patent: April 13, 2004Assignee: Canon Finetech Inc.Inventors: Iwao Kawamura, Ryouma Suzuki, Kazuhiro Murakami, Naoki Kiyohara, Kensuke Izuma, Kiyokazu Namekata, Tatsuo Fujimura, Mitsuharu Takizawa, Keiko Nazuka

Patent number: 5148089Abstract: An apparatus and method for controlling the velocity of a motor controls the motor by fuzzy inferential reasoning in a transitional period when the motor is started, changed in speed, reversed or stopped. Such fuzzy control eliminates an increase in the length of the transitional period caused by a limitation in supply current under conventional PLL control and makes possible a rapid transition to a target velocity. A plurality of fuzzy rules are provided and one of these fuzzy rules is selected in accordance with the length of the previous transitional period, thereby suppressing the effects of load fluctuation and the influence of a fluctuation in torque caused by a rise in temperature. Therefore, the length for transitional control of a motor can be shortened and the apparatus can be reduced in size.Type: GrantFiled: August 29, 1990Date of Patent: September 15, 1992Assignee: Canon Kabushiki KaishaInventors: Hideki Adachi, Mitsuharu Takizawa, Miho Nakayama, Taisei Fukada, Shinichi Nakamura, Satoshi Kuroyanagi, Hisatsugu Tahara, Hiroshi Ozaki, Masanori Miyata
