A feeding device in accordance with the present invention includes an arm mounted such that one edge thereof is rotatably supported and is capable of moving freely in the horizontal plane, a rotating section rotatably supported by the other edge of the arm and is capable of rotating freely in the horizontal plane to at least two paper feed positions, i.e. longitudinal and lateral feed positions, and a pivotal paper holding plate that is capable of rising. A rotating device is rotatably mounted in the vicinity of a corner of the rotating section and moves back and forth in a straight line in a direction orthogonal to the paper feed direction and permits the rotating section to rotate. A flexible joint is provided which is capable of pivoting in at least two directions and supports the pivotal paper holding plate at one point located in the corner formed by a non-feeding side of the rotating section when the rotating section is set in the longitudinal feed position and the non-feeding side of the rotating section when the rotating section is set in the lateral feed position, such that the pivotal paper holding palte uses the non-feeding side of the rotating sections as fulcrums when the pivotal paper plate pivots and rises.

Driving device for a rotatable cassette

A device for storing rectangular sheets to be fed into a sheet conveying path in an image forming apparatus comprises a sheet tray for stacking thereon the rectangular sheets. The movable tray having a first and second sides used for longitudinal and lateral feeds of a sheet with respect to the sheet conveying path, respectively, is movably supported on a base member for the movement between a first and second positions at which the first and second sides of the sheet tray are located at a constant position for the longitudinal and lateral feeds of the sheet, respectively. A connecting member is joined to the sheet tray at a position near the intersection of the first and second sides thereof. A reciprocating device is provided for causing the sheet tray to be moved between the first and second positions by reciprocating the connecting member in a direction transverse to the feeding direction of the sheet with respect to the sheet conveying path. A locking device is provided for locking the sheet tray to the base plate at diagonal positions to the connecting member with respect to the first and second positions of the sheet tray.
