Patent application number | Description | Published |
20080315515 | Image forming apparatus - An image forming apparatus includes a first guide portion disposed to be movable for opening a transportation path of a medium; a second guide portion disposed to be movable for opening the transportation path and arranged adjacent to the first guide portion; a first transportation member for transporting the medium to the transportation path; and a second transportation member for discharging the medium from the transportation path to outside the image forming apparatus. Further, when the first guide portion and the second guide portion close the transportation path, the second guide portion is arranged to guide a rear edge of the medium. | 12-25-2008 |
20090206545 | Medium feeding cassette and image forming apparatus - A medium feeding cassette includes a cassette main body, a cassette extension member mounted to the cassette main body so as to be movable with respect to the cassette main body, and a locking mechanism configured to lock the cassette extension member at a predetermined position with respect to the cassette main body according to a size of the medium. The locking mechanism includes a locking member and a first locking groove that engage each other so as to lock the cassette extension member in the predetermined position. The locking member moves in a direction to release locking of the cassette extension member when a force is applied to the cassette extension member in a direction to retract the cassette extension member into the cassette main body. | 08-20-2009 |
20100244373 | Medium feeding device and image forming device - A medium feeding device includes: a sheet holding unit, which holds a sheet and is pivotally attached to a device main unit so that the sheet holding unit is pivotal between open and closed positions; a sheet feeding roller that is located close to the sheet holding unit and that feeds the sheet to the inside of the device main unit; and a driving shaft that is located on an axis that is different from a rotation shaft for the sheet feeding roller and that drives the rotation shaft. | 09-30-2010 |
20110233854 | Media-loaded device and image forming apparatus - A media-loaded device includes a main body and a guide unit. The main body, in which media are stackable, has a first engaging member. The guide unit is movable relative to the main body and has a disengaging member. The disengaging member has a second engaging member that engages with the first engaging member. The second engaging member is disengaged from the first engaging member by an external force applied to the disengaging member in a stacking direction of the media. | 09-29-2011 |
20120306149 | SHEET STORAGE CASSETTE AND IMAGE FORMING APPARATUS - A sheet storage cassette can include a sheet supporting board and a restriction guide. The sheet supporting board can support at least one sheet thereon. The restriction guide can be arranged on the sheet supporting board and include a sheet holding surface that is substantially perpendicular to the sheet support board. The restriction guide can further include a mark indicated part at an upper side thereof, where the mark indicated part can extend at least partly along a plane that intersects a plane of the holding surface and can indicate a maximum storage capacity level of the sheet storage cassette. | 12-06-2012 |
20130285310 | SHEET STORAGE CASSETTE AND IMAGE FORMING APPARATUS - A sheet storage cassette can include a sheet supporting board and a restriction guide. The sheet supporting board can support at least one sheet thereon. The restriction guide can be arranged on the sheet supporting board and include a sheet holding surface that is substantially perpendicular to the sheet support board. The restriction guide can further include a mark indicated part at an upper side thereof, where the mark indicated part can extend at least partly along a plane that intersects a plane of the holding surface and can indicate a maximum storage capacity level of the sheet storage cassette. | 10-31-2013 |
20140175739 | MEDIUM CARRYING DEVICE AND IMAGE FORMING APPARATUS - A medium carrying device includes a first pair of rollers that forms a nip part and carries a medium, the nip part being defined as an area where the rollers contact each other applying a pressure to other, a guide part that guides the medium to the first pair of rollers, and a medium detection member that includes a tip end part and a pivoting fulcrum and that is pivoted around the pivoting fulcrum by the medium as the medium moves along the guide part. In a case of being viewed from a roller axial direction of the first pair of rollers, the tip end part passes the nip part when the medium detection member pivots around the pivoting fulcrum as a center. | 06-26-2014 |
20150309462 | MEDIUM TRANSPORTATION APPARATUS, IMAGE FORMING APPARATUS, AND METHOD OF ASSEMBLING MEDIUM TRANSPORTATION APPARATUS - A medium transportation apparatus includes a transportation portion for transporting a medium; a first structure unit for forming a first transportation path to guide and transport the medium in a first direction from an upstream side in a medium transportation direction toward a downstream side in the medium transportation direction; and a second structure unit for forming an accommodation space to accommodate a part of the first structure unit. The first structure unit includes a first region disposed outside the accommodation space on the downstream side in the medium transportation direction and a second region disposed inside the accommodation space on the upstream side in the medium transportation direction. | 10-29-2015 |
