Patent number: 7621615Abstract: An object of the present invention is to provide a print medium identifying device that can accurately detect various print media. Thus, according to the present invention, a light emitting section (LED) irradiates a surface of a print medium P with ultraviolet light and different light of a longer wave. A light receiving section (regular-reflection photo sensor and diffusive-reflection photo sensor) receives the light reflected by the surface of the print medium P to output a signal corresponding to the quantity of light received. Identifying section (signal processing section) identifies the type of the print medium on the basis of a signal output by the light receiving section when the print medium is irradiated with the ultraviolet light and a signal output by the light receiving section when the print medium is irradiated with the different light.Type: GrantFiled: March 29, 2005Date of Patent: November 24, 2009Assignee: Canon Kabushiki KaishaInventors: Shoji Kikuchi, Akira Miyakawa, Mitsuyuki Fujibayashi

Patent number: 6388774Abstract: A serial-scanning-type image reading apparatus includes a plurality of light guides. One end of each of the light guides is connected to a supporting plate provided for supporting an original thereon at a position a constant distance apart from a scanner head. The connecting position of each light guide to the supporting plate is in a region within a range in which the scanner head is movable but out of a region in which the original is transported. Each light guide extends from the connecting position to an exterior part of the apparatus. One of the plurality of light guides is selected depending on the operating status of the apparatus, and the scanner head is positioned so that light emitted from a light source is guided through the selected light guide to the exterior part of the apparatus. Thus, it is possible to provide a low-cost indicator for indicating the operating status of the image reading apparatus while maintaining the scanning element and the scanning region covered by a cover.Type: GrantFiled: August 20, 1998Date of Patent: May 14, 2002Assignee: Canon Kabushiki KaishaInventors: Tetsuji Kurata, Shoji Kikuchi

Patent number: 5737095Abstract: An image reading apparatus includes a plurality of light sources for illuminating an original, a photoelectric conversion device for converting light from the original illuminated by each of the plurality of illuminating means, and a discriminating circuit for discriminating whether or not any image exists on the original, based on image signals output from the photoelectric conversion device at least when the original is illuminated with light from one of the light sources, which possesses spectral characteristics including green. A control circuit controls the apparatus so that, when the discriminating circuit has determined that no image exists on the original, the manner of reading of the image with the light sources other than the light source employed in the discrimination performed by the discriminating circuit is changed from the manner of reading of the image with the light source employed in the discrimination.Type: GrantFiled: February 26, 1996Date of Patent: April 7, 1998Assignee: Canon Kabushiki KaishaInventors: Shoji Kikuchi, Mineo Nozaki

Patent number: 5588757Abstract: A recording apparatus for performing recording uses a carriage mounted with a recording head moving along a guide shaft. The recording apparatus includes a magnetic linear encoder consisting of a scale element magnetized and a detection unit for detecting magnetized information magnetized to the scale element. Provided also are clicks formed on any one of the detection unit and the carriage and click engaging portions formed in the other one of the detection unit and the carriage. The clicks engage with the click engaging portions, whereby the detection unit is snap-locked to the carriage. This enables the detection unit of the magnetic linear encoder to be readily attached to the carriage and besides, when attached, prevents disorder of the information magnetized to the scale element. Further, even when a position of the carriage shifts corresponding to sheets having different thicknesses, a sliding load of the carriage does not change.Type: GrantFiled: March 20, 1996Date of Patent: December 31, 1996Assignee: Canon Kabushiki KaishaInventors: Yasuhiro Unosawa, Shinji Kanemitsu, Makoto Kashimura, Makoto Takemura, Shoji Kikuchi, Shinya Matsui, Toshiyuki Onishi, Tetsuhiro Nitta, Masaru Sato, Hisashi Morioka
