20100194030 | DRIVE TRANSMISSION APPARATUS AND FEEDING APPARATUS - A drive transmission apparatus includes a sun gear driven by a drive source, a planetary gear, a supporting member that supports the planetary gear capable of revolving around the sun gear in a rotatably engaged state with the sun gear, a driven gear that is engaged with the planetary gear when the planetary gear revolves and moves to an engagement position by the rotation of the sun gear in a first direction, and a rotational force providing unit that provides a rotational force to the driven gear to rotate the sun gear in a second direction opposite to the first direction via the planetary gear when the planetary gear is engaged with the driven gear. When the sun gear is rotated in the second direction by the drive source, the rotational force providing unit blocks the revolution of the planetary gear by rotating the planetary gear via the driven gear. | 08-05-2010 |
20110133393 | SHEET MATERIAL FEEDING APPARATUS AND IMAGE FORMING APPARATUS - The sheet material feeding apparatus according to this invention comprises a sheet material stacking unit selectively located at a feeding position for feeding a sheet material and at a standby position for non-feeding a sheet material; a first holding force applying unit configured to apply a first holding force and a second holding force applying unit configured to apply a second holding force for holding the guide member to the sheet material stacking unit; and a restraining unit configured to restrain the second holding force applying unit from applying the second holding force when the sheet material stacking unit is in the standby position. | 06-09-2011 |
20110211007 | PRINTING APPARATUS AND JAM RESTORATION METHOD IN PRINTING APPARATUS - In the event that occurrence of a jam has been detected during conveyance of a sheet, the sheet is cut at a cutter unit, and a user is prompted to perform manual jam restoration processing according to the location where the jam has occurred. If the jam has occurred upstream from the cutter unit, the cut sheets left downstream from the cutter unit are discharged as completed articles. | 09-01-2011 |
20110211897 | PRINTING APPARATUS, SHEET PROCESSING APPARATUS, AND SHEET WINDING DEVICE - A device includes a winding rotary member having a cylindrical shape; a holder having a rotating member, which is provided in the vicinity of a cylindrical surface of the winding rotary member, capable of nipping and conveying the sheet; a first driving mechanism configured to rotate the winding rotary member; and a second driving mechanism configured to rotate the rotating member. The winding rotary member rotates with the sheet is nipped with the rotatable holder, whereby the sheet is wound around the winding rotary member. | 09-01-2011 |
20110239839 | APPARATUS AND METHOD FOR CUTTING SHEET - A sheet is cut between a first conveying unit and a second conveying unit in a state in which the first and second conveying units halt and in which an upstream conveying unit conveys the sheet at a first speed; after the sheet is cut, the first conveying unit conveys the sheet at a second speed higher than the first speed to reduce a slack formed during the halting; after the sheet is cut, the second conveying unit conveys the downstream-side sheet at a third speed higher than the first speed; if the third conveying unit is nipping the sheet during cutting, the third conveying unit conveys the sheet at the third speed; and if the third conveying unit is not nipping the sheet, the third conveying unit conveys the sheet at the third speed or a fourth speed after the detecting unit detects the sheet. | 10-06-2011 |
20110262153 | PRINTING APPARATUS AND SHEET PROCESSING APPARATUS - At least one of processing units is capable of being pulled out of a main body of an apparatus during the occurrence of a sheet conveyance jam. A first cutter and a second cutter are arranged in the vicinity of the processing unit. The first cutter is configured to cut the sheet on an upstream of the processing unit. The second cutter is configured to cut the sheet on a downstream thereof. When the processing unit is pulled, the sheet is cut on the upstream and downstream of the processing unit. | 10-27-2011 |
20120194597 | METHOD OF PRINTING AND PRINTING APPARATUS - A reference mark is formed for cutting a sheet in a region between a first image printed on the sheet being conveyed and a second image, and the sheet is cut based on the detected reference mark. The second image is printed such that the length of the region in a conveying direction in which the sheet is conveyed corresponds to the length of the first image in the direction. | 08-02-2012 |
20130100219 | SHEET CONVEYANCE APPARATUS, PRINTING APPARATUS, AND JAM CLEARING METHOD - A sheet conveyance apparatus comprising: a first processing unit including a first sheet conveyance mechanism; a second processing unit including a second sheet conveyance mechanism; a cutting unit, interposed between the first processing unit and the second processing unit, for cutting the sheet; and a controlling unit that controls, in a case of trouble with sheet conveyance, driving of the first sheet conveyance mechanism until an end of the sheet reaches the first processing unit side beyond a cutting position of the cutting unit. | 04-25-2013 |
