Patent number: 11718109Abstract: An information processing apparatus includes an acquisition unit, a decision unit, a determination unit, and a change unit. The acquisition unit acquires a measurement result regarding a printing medium characteristic value. The decision unit decides a candidate for a printing medium type based on the acquired measurement result, and a reference characteristic value of each of printing media types set in advance to identify a type of the measured printing medium. Information associated with the printing medium type to be printed is input. The determination unit determines whether to change the reference characteristic value of the printing medium type associated with the input information based on the measurement result and the printing medium type associated with the input information. Wherein, when the determination unit determines to change the reference characteristic value, the change unit changes the reference characteristic value of the printing medium type based on the measurement result.Type: GrantFiled: September 29, 2021Date of Patent: August 8, 2023Assignee: Canon Kabushiki KaishaInventors: Takehiko Kasamatsu, Yuki Igarashi, Koji Suda, Fumikazu Nishikawa, Yasushi Morimoto, Keiko Harada, Ryoma Ono

Patent number: 7539454Abstract: In a conventional printing apparatus with a plurality of paper feed ports, since a paper type limits the paper feed port usable for paper feed, a user must know in advance a paper feed port to set a paper sheet. This arrangement is not user-friendly. A printing apparatus according to the present invention, however, holds table information indicating the correspondence between paper types and paper feed ports usable for paper feed. When a paper type is designated together with input print data, information on a paper feed port usable for paper feed is acquired from the table information. A message is displayed to prompt the user to set a paper sheet on the paper feed port usable for paper feed so that the user can set an appropriate paper sheet.Type: GrantFiled: February 1, 2007Date of Patent: May 26, 2009Assignee: Canon Kabushiki KaishaInventor: Fumikazu Nishikawa

Patent number: 5612598Abstract: A drive frequency control system is used for a vibration driven motor including a vibrating member which generates a vibration therein upon application of a frequency signal to an electro-mechanical energy conversion element therein, and which uses the vibration as a driving force. The system includes a power supply circuit for supplying an electric power to the vibration driven motor, and a detection circuit for detecting a power supply voltage level of the electric power supplied by the power supply circuit, the detection circuit determining whether the power supply voltage level is less than a predetermined voltage level. A control circuit performs frequency control of the frequency signal of the basis of the determination of the detection circuit.Type: GrantFiled: December 30, 1992Date of Patent: March 18, 1997Assignee: Canon Kabushiki KaishaInventors: Hajime Fukui, Akio Atsuta, Fumikazu Nishikawa

Patent number: 5493163Abstract: A driving device drives a movable member, such as a lens barrel, using a vibration motor through a gear train. The scanning speed of the driving frequency of a periodic signal applied to the motor when the motor is activated is varied according to a backlash of the gear train. In this manner, a movable member can be driven to effect a fine focus adjustment regardless of the existence or non-existence of a backlash in the gear train.Type: GrantFiled: September 29, 1994Date of Patent: February 20, 1996Assignee: Canon Kabushiki KaishaInventor: Fumikazu Nishikawa

Patent number: 4670791Abstract: This invention is directed to a method and system which employs a distinguishing document placed between each document set which distinguished the documents for one destination from the documents of another destination. In accordance with this invention, the number of documents within each set are counted by counting the documents fed until the distinguishing document is detected, this number is then compared with the number entered in advance for each destination. When a difference between these numbers occurs, it is then determined that double feeding has occurred and a warning is indicated.Type: GrantFiled: July 27, 1983Date of Patent: June 2, 1987Assignee: Tokyo Shibaura Denki Kabushiki KaishaInventors: Tsuneo Murata, Yoshihiro Hirata, Toshio Miyagawa, Fumikazu Nishikawa
