Patent number: 6854904Abstract: A printing/verifying direction section in a control section directs a thermal head controller and a sheet conveying motor controller to do printing in accordance with a detection result by a sheet position detection sensor, so as to print image data in a printing image storage section on a sheet (label) by a thermal head. Further, based on printing position data from a printing data storage section, the printing/verifying direction section directs a verification section controller to operate a scanner controller so as to permit a scanner to read an image of a printed mark. The verification section controller compares the read image with printing data in the printing data storage section to judge whether the image is good or no good. When it is no good, the mark is returned to a printing position by the thermal head by a direction of a printing/verifying controller, so that the thermal head prints an overwriting image in an overwriting image storage section on the mark.Type: GrantFiled: September 22, 2003Date of Patent: February 15, 2005Assignee: Tohoku Ricoh Co., Ltd.Inventors: Genzi Oshino, Atsushi Okamura

Patent number: 5476233Abstract: In a stacker for successively stacking cut papers on a bottom plate, a winding shaft for winding a non-cut continuous paper therearound is provided on a back side plate so as to project substantially perpendicularly to the paper restriction surface of the back side plate. This structure of the stacker makes it possible to stack the cut papers successively on the bottom plate and also makes it possible to easily wind the continuous paper around the winding shaft. In the stacker for successively stacking cut papers therein by inserting a cut paper beneath the previous stacked papers comprising a paper press for pressing the stacked papers from the top surface thereof and a press force switching mechanism for contacting the paper press and applying press force to the stacked cut papers until the stack height of the stacked papers reaches a prescribed value and for releasing the application of the press force when the stack height of the stacked papers exceeds the prescribed value.Type: GrantFiled: December 10, 1993Date of Patent: December 19, 1995Assignee: Tohoku Ricoh Co., Ltd.Inventors: Genzi Oshino, Katsuhiko Obata, Hideaki Matsuda

Patent number: 5414450Abstract: A thermal printer comprising a line type thermal head which is arranged substantially in parallel with the shaft of a platen and is swingably supported about the longitudinal central portion thereof can obtain clear printed letters and prevent the abrasion of the platen due to the direct contact between the thermal head and the platen even if the recording paper varies in width or thickness or is set on the platen one-sided. To achieve the above object, members for restricting the swinging of the thermal head are prodded at both end portions thereof, one of the members being adjustable in its restricting position and the thermal head is supported by a head supporting means composed of a head plate, a head frame and tension springs so as to be movable toward or away from the platen so that the thermal head is separated from the platen according to the thickness of the recording paper and does; not contact the platen.Type: GrantFiled: December 3, 1992Date of Patent: May 9, 1995Assignee: Tohoku Richo Co., Ltd.Inventors: Genzi Oshino, Isamu Suzuki

Patent number: 5407081Abstract: A stacker has a feed unit for feeding separate sheets in a direction, a stacking unit for stacking the separate sheets in a normal position, and a sheet classifying mechanism for shifting a sheet into a position different from the normal position, upstream of the stacking unit with respect to the direction. Sheets to be used to classify respective batches of sheets stacked by the stacking unit can selectively be shifted into the position different from the normal position by the sheet classifying mechanism. Since those shifted sheets can easily and clearly be recognized by the operator, the batches of stacked sheet can be sorted out with ease. The sheets remain sightly in appearance as no classifying ink mark is applied to those sheets used to classify the batches of stacked sheets.Type: GrantFiled: March 31, 1994Date of Patent: April 18, 1995Assignee: Tohoku Ricoh Co., Ltd.Inventors: Genzi Oshino, Hideaki Matsuda, Katsuhiko Obata

Patent number: 5248993Abstract: The invention relates to a thermal printer and a printing method thereby, using a step motor for feeding a sheet of paper, a scanning type thermal head and a control unit by which the paper feeding operation is temporarily stopped and the printing operation is restarted after the stopped period. This thermal printer further comprises a delay drive unit which drives the thermal head with delay of one or two clock periods, predetermined as a control parameter for this printing operation, by a phase switch timing point for the step motor, in response to the time-lag defined by the phase switch timing point to an actual paper feeding motion; and a pre-print unit which outputs a command signal to begin the printing operation of the thermal head for printing one or more times the print data which follows the final print data of when the paper feeding operation was stopped, prior to the above described regular drive operation of the thermal head at the restart of the printing operation.Type: GrantFiled: September 6, 1991Date of Patent: September 28, 1993Assignee: Tohoku Ricoh Co., Ltd.Inventors: Genzi Oshino, Yutaka Shibata, Hideaki Matsuda
