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

Patent number: 5584591Abstract: When format information is changed, print area check data is generated as per the changed format information (S25). If the check data is found not to be printable within the print area of the tape defined by the printable width and set tape length ("YES" in S27), the changed format information is invalidated (S28), and a message indicating what has taken place appears on the display (S29). Whenever a character or the like is input, the corresponding print check data is generated (S33). If the data is found to be printable within the print area ("NO" in S35), a print-like image of that character is displayed; if the data is found not printable ("YES" in S35), a message indicating the unavailability of printing is displayed (S38), and the corresponding text appears on the display unit (S40).Type: GrantFiled: December 12, 1994Date of Patent: December 17, 1996Assignee: Brother Kogyo Kabushiki KaishaInventors: Masaharu Mori, Mayumi Nishio, Mika Oshige, Sachie Kanda

Patent number: 5577848Abstract: A keyboard where no finger pressure is needed to input data, that uses rows of emitters opposed by rows of detectors to detect a finger position, that is environmentally sealed, and inherently intrinsic safe. The keyboard has a mouse function so an operators finger can be tracked to position a cursor on a host display, and input normal keyboard functions. The keyboard has a field changeable coded overlay with indicia thereon so a scan pattern, ambient reference level or other application specific variables can be changed without breaking the environmental seal or powering down the keyboard. Further, the different scan patterns can include scanning the finger position by multiple emitter detector pairs at angles other than ninety degrees to give a cross check of detection. These said scan patterns can be further optimized to scan angled sets of keys and to adjust to different ambient light conditions so errors can be detected by the emitter detector pair closest to detection of a finger.Type: GrantFiled: September 23, 1994Date of Patent: November 26, 1996Inventor: James H.

Patent number: 5564848Abstract: A media handling subsystem picks a media sheet from a stack, then moves the picked sheet along a media path. Any skewing of the media sheet existing in the media stack or occurring during the pick cycle is removed before the sheet reaches a position to receive print markings. In particular, the alignment of the skewed media sheet is altered (i.e., the sheet is moved) to square the media sheet to the media path. An electro-optic sensor detects when the top of a media sheet enters between a drive roller and pinch roller. Upon entering, the media sheet moves a mechanical flag into the light circuit of the optical sensor. After the media sheet trips the flag, the drive roller moves the top edge of the media sheet backward along the media path out of the grasp of the pinch roller and drive roller. As the sheet moves out of the grasp, the top edge of the sheet falls into squared alignment with the drive roller and pinch roller. The squared media sheet then is moved forward tripping the flag again.Type: GrantFiled: June 7, 1995Date of Patent: October 15, 1996Assignee: Hewlett-Packard CompanyInventor: Jason Quintana

Patent number: 5547296Abstract: A method of controlling a transportation velocity of a printhead carriage of a serial printer is disclosed. The printhead carriage is driven by a motor via a timing belt. First, a characteristic equation, which includes a motor speed, a current applied to said motor, an equivalent disturbance indicating environmental variations affecting said motor speed, is discreted. Thereafter, the equivalent disturbance is estimated using the characteristic equation which has been discreted. A value of the equivalent disturbance is determined and subsequently, a value of the equivalent disturbance compensating level is calculated using a discrete low pass filter. Finally, a current to be applied to said motor is obtained by adding a compensating level of the controller to the level of the equivalent disturbance.Type: GrantFiled: May 24, 1994Date of Patent: August 20, 1996Assignee: NEC CorporationInventor: Naotoshi Iwazawa
