20150069697 | SHEET STACKING APPARATUS, SHEET STORAGE APPARATUS AND IMAGE FORMING APPARATUS EQUIPPED WITH THE SAME - A sheet stacking apparatus includes a sheet stacking unit having a stacking member, a contact member, a moving unit, and a regulating member. The contact member contacts an end portion of a sheet stacked on the stacking member. The moving unit moves the contact member from a standby position to a movement position to move the stacked sheet. The regulating member regulates, at a regulation position, a position of the stacked sheet from above, and moves from the regulation position by being pushed by the conveyed sheet. In a sheet width direction orthogonal to a direction in which the sheet is conveyed, the contact member and the regulating member are arranged at different positions, and in a thickness direction of the stacked sheet, an upper surface of the contact member located at the standby position is located above a lower surface of the regulating member located at the regulation position. | 03-12-2015 |
20150102556 | IMAGE FORMING APPARATUS - An image forming apparatus which include a sheet storage portion and a stacker portion and from which a user can easily receive a sheet is provided. | 04-16-2015 |
20150110538 | SHEET STORAGE DEVICE AND IMAGE FORMING APPARATUS - The present invention provides a sheet storage device having a high sheet receiving performance and whose size is reduced. | 04-23-2015 |
20150203319 | SHEET STORING APPARATUS AND IMAGE FORMING APPARATUS EQUIPPED THEREWITH - A sheet storing apparatus includes a plurality of sheet storing units. Each of the sheet storing unit includes a fixed stacking portion configured to stack thereon a sheet conveyed by conveyance roller pairs, and a pushing unit configured to contact an edge of the sheet stacked on the stacking portion and to move the sheet in a direction substantially perpendicular to the sheet conveyance direction. A drive transmission unit for transmitting a driving force generated by a motor to drive the pushing unit is located upstream of the fixed stacking portion with respect to a direction in which the pushing unit moves the sheet. When the pushing unit is moving the sheet, a part of the drive transmission unit enters the inside of a sheet stacking range of the fixed stacking portion. | 07-23-2015 |
20150291375 | SHEET STORAGE APPARATUS AND IMAGE FORMING APPARATUS - Provided is a sheet storage apparatus for storing a sheet conveyed by a sheet conveyance unit, wherein at a home position, at least a part of a sheet presence detection flag overlaps a rotational axis of a sheet presence detection flag of an adjacent sheet storage unit in a vertical direction. | 10-15-2015 |
20150298934 | IMAGE FORMING APPARATUS AND IMAGE FORMING SYSTEM - An image forming apparatus includes an apparatus main body, an image forming unit, a storage portion, a moving unit, a stack portion, and a conveyance unit, wherein if the storage portion can store the sheet, the conveyance unit conveys the sheet on which the image has been formed to the storage portion, and if the storage portion cannot store the sheet, the image forming apparatus transitions to a standby state and waits for a discharge instruction, and when the discharge instruction is received, the conveyance unit conveys the sheet on which the image has been formed to the stack portion. | 10-22-2015 |
20150301490 | IMAGE FORMING APPARATUS - An image forming apparatus includes an apparatus main body including an opening, an image forming unit, a storage portion, a moving unit, and a control unit. The control unit switches between a first state and a second state, the first state being a state where the moving unit is prohibited from moving and exposing a first sheet when information about a second user different from a first user who has instructed to print a first sheet is received, and the second state being a state where the moving unit is permitted to move and expose the first sheet if information about the second user is received. | 10-22-2015 |
20150307295 | IMAGE FORMING APPARATUS - An image forming apparatus of the invention includes an image forming unit configured to form an image on a sheet; a plurality of storage portions each configured to store the sheet with the image formed thereon by the image forming unit; an opening configured to expose the sheet stored in the storage portion to the outside; and a sheet moving unit configured to move the sheet until a leading edge of the sheet stored in the storage portion passes the opening and a portion of the sheet is exposed from the opening to the outside. The sheet moving unit exposes sheets stored in a plurality of the storage portions in a stacked manner from the opening. | 10-29-2015 |
