Publication number: 20060183611Abstract: Machining is possible in such a manner that an optional position of a workpiece is positioned just under a tool by rotation of a turn table in a C-axis direction and movement of a spindle on a Y-Z plane, so that a width of a main unit in a X-axis direction can be made shorter in comparison with machining by moving the turn table in the X-axis direction. Besides, the turn table located on a front side of the main unit, an ATC located on the rear side thereof, and a separated control panel located on the rear side of the ATC, independent from the main unit can also make the width of a machining center in the X-axis direction shorter.Type: ApplicationFiled: April 21, 2006Publication date: August 17, 2006Inventors: Takao Taniguchi, Toshiyuki Andou, Mitsuhiro Yamada, Kazutaka Murai, Yuichiro Yoshimura, Jiro Nishida, Atsushi Kohama, Shigeto Noma, Michio Norimatsu, Seiichi Kodama, Haruhiko Koike

Patent number: 6963331Abstract: The invention aims to provide a coordinate input apparatus having high detection reliability and high efficiency and to control the influence of ambient light using a simple structure. The apparatus detects a light spot flashing on and off in a predetermined cycle and incident at a desired position on a coordinate input screen, and includes a detection device having photoelectric conversion elements corresponding to N pixels for detecting a light spot coordinate. The difference between signals from photoelectric elements in light emission state and in light non-emission state at each N pixel is found, and the smaller of the difference signals of the m-th pixel having the maximum difference signal is set as a threshold value. Effective pixels are identified based on the threshold value, and the coordinate is calculated by using the difference data of the selected effective pixels.Type: GrantFiled: March 14, 2000Date of Patent: November 8, 2005Assignee: Canon Kabushiki KaishaInventors: Katsuyuki Kobayashi, Masahide Hasegawa, Kiwamu Kobayashi, Masaaki Kanashiki, Atsushi Tanaka, Yuichiro Yoshimura

Patent number: 6664954Abstract: A cap covering a light-emitting element attached to the distal end of an indicator is held by a sliding member, and is slidably attached axially along the indicator. By pressing/separating the cap against/from a coordinate input surface, a tact switch operates interlockingly with the cap to switch driving control of the light-emitting element. For example, the light-emitting element is driven by pressing the cap, and driving of the light-emitting element is stopped by separating the cap. Since the cap covers the light-emitting element, the light-emitting element can be prevented from being worn and scratched. Driving control of the light-emitting element need not be additionally switched, resulting in high operability.Type: GrantFiled: November 3, 1999Date of Patent: December 16, 2003Assignee: Canon Kabushiki KaishaInventors: Yuichiro Yoshimura, Masahide Hasegawa, Kiwamu Kobayashi, Masaaki Kanashiki, Atsushi Tanaka, Katsuyuki Kobayashi

Patent number: 6611258Abstract: In a pen-input computer or the like, it is impossible to distinguish an input method and to execute a proper process according to the input method. A touch panel driver generates finger-input coordinate values for a display screen. A digitizer driver generates pen-input coordinate values for the display screen. A processor receives the coordinate values and additional information indicative of either the finger-input or the pen-input from a source discriminator, starts an inputting process according to the input method, and allows a virtual keyboard to be displayed onto the screen or allows a “CHR input pad” window to be opened.Type: GrantFiled: December 31, 1996Date of Patent: August 26, 2003Assignee: Canon Kabushiki KaishaInventors: Atsushi Tanaka, Yuichiro Yoshimura, Ryozo Yanagisawa, Katsuyuki Kobayashi, Masaki Tokioka, Hajime Sato

Patent number: 6570558Abstract: An influence by a vibration which is transmitted in the air is reduced, thereby preventing an erroneous detection of coordinates or a deterioration in a detecting precision. An elastic resin sheet is arranged on a coordinates input surface side of a vibration transmission plate so as to have a gap between the resin sheet and the vibration transmission plate and is fixed by an adhesive layer. When coordinates are inputted by a vibrator pen, namely, when a vibration is inputted, the resin sheet is warped by a writing pressure of the vibrator pen and the resin sheet comes into contact with the vibration transmission plate. Therefore, the vibration applied by the vibrator pen is efficiently transmitted to the vibration transmission plate.Type: GrantFiled: December 30, 1996Date of Patent: May 27, 2003Assignee: Canon Kabushiki KaishaInventors: Yuichiro Yoshimura, Atsushi Tanaka, Ryozo Yanagisawa, Katsuyuki Kobayashi, Masaki Tokioka, Hajime Sato
