A toner transporting device includes a screw that includes a spiral fin wound around a shaft portion and transports toner in the axial direction, and a toner crushing member that is disposed along the transport direction of the toner and crushes accumulated toner, wherein the toner crushing member includes a base portion that extends along the shaft portion of the screw, and a flexible plate member which is disposed at a position in which the flexible plate member bumps into and contacts the fin, and in which the downstream side in the transport direction of the toner in the screw is fixed to the base portion and the upstream side is separated from the base portion.
摘要:
A cutting apparatus configured to cut a sheet or a sheet bundle includes a cutting blade whose blade surface has a plurality of grooves. In the cutting apparatus, a scraping member enters the grooves provided on the blade surface to scrape off cutting scraps remaining after a cutting operation. Accordingly, the cutting apparatus can scrape off cutting scraps from the cutting blade even if the adhesive force of the cutting scraps is great.

A display apparatus 100 of the present invention includes: a memory 130; a display 101; an operation part 110; and a controller 150. The controller 150 controls the display 101, in the case where the image of image data acquired in the memory 130 is displayed as a stereoscopic image, such that the image of the image data acquired in the memory 130 is displayed as a planar image when an instruction for selection becomes receivable by the operation part 110.
摘要:
A recording material stacking apparatus equipped with a plurality of discharge ports and a plurality of stacking trays can be set to normal mode and large capacity stacking mode each having a different maximum loading capacity. A stacking tray on the upper side has a plurality of lower limit positions and uses a lower limit position located on the upper side when normal mode is selected. On the other hand, it uses a lower limit position located on the lower side when the large capacity stacking mode is selected. The lower limit position located below a stacking tray on the upper side when this large capacity stacking mode is selected exists at a position in which it blocks a lower discharge port of sheets. Selection of the large capacity stacking mode and normal mode is executed according to a result of computation from data input through an input portion.
摘要:
A sheet stacking apparatus includes a gripper configured to discharge a sheet, a plurality of stacker trays arranged in a row and configured to stack the discharged sheet, and a guiding unit configured to guide the discharged sheet to a predetermined position. The plurality of stacking trays are horizontally arranged so that a large number of sheets can be stacked without increasing the size of the sheet stacking apparatus.
