  • Publication number: 20150117928
    Abstract: A recording medium storage apparatus has a storage cassette and a lock mechanism. The lock mechanism restricts movement of the storage cassette in the drawing direction. The lock mechanism has an engaging portion on an apparatus body and an engaged portion on the storage cassette. While the storage cassette is drawn out of the apparatus body, an abutting portion of the engaging portion moves along a first slope on the engaged portion toward a peak portion while swinging in a second direction in which it retracts from the engaged portion, and meanwhile the engaged portion rotates in a third direction so that the peak portion is displaced from a protruding position to a guiding position.

  • Publication number: 20150110538
    Abstract: The present invention provides a sheet storage device having a high sheet receiving performance and whose size is reduced. A point 272 of intersection of a first upper guide and a second upper guide is located upstream from a point 271 of intersection of a first lower guide and a second lower guide in a sheet conveyance direction. Thus, the size of the sheet storage device can be reduced while the sheet receiving performance remains unaffected.

    Abstract: A sheet stacking device includes a device main body, a sheet discharge unit, a sheet stacking portion and a sheet detector. The sheet discharge unit discharges sheets. The sheet stacking portion includes a sheet stacking surface on which the sheets are to be stacked. The opening is formed in the sheet stacking surface. The sheet detector includes a detection piece capable of projecting upwardly of the sheet stacking surface from the opening. The sheet detector detects a first state, a second state and a third state. The first state is a state where no sheet is placed on the sheet stacking surface. The second state is a state where a first number of the sheets discharged are placed on the sheet stacking surface. The third state is a state where a second number of the sheets larger than the first number are placed on the sheet stacking surface.
