A sheet supporting device comprises a first supporting unit, a second supporting unit provided to the first supporting unit and drawable in a draw direction from an insert position, a supporting portion on which sheets are supported and provided ascendably/descendably in the first supporting unit, first and second turning portions configured to turn in linkage with an ascendance and descendance move of the supporting portion, an elevation portion, and an indicator. The elevation portion, whose one end is connected with the first turning portion and another end is connected with the second turning portion, is configured to form a link mechanism together with the first and second turning portions and the first supporting unit. The indicator is provided in the second supporting unit and indicates an amount of the sheets supported on the supporting portion by moving in response to an ascendance and descendance move of the elevation portion.

There is provided a sheet tray including: first, second and third trays. The second tray moves between a first position and a second position in which an overlapping area is smaller than that obtained in the first position. The third tray includes a third support surface and a fourth support surface. The third support surface includes a protrusion which protrudes upward to be positioned above the first support surface in a state that the third tray is in the first pivoting position. The third tray overlaps with the first support surface in a state that the second tray is in the first position and that at least a part, of the third tray, except for the protrusion is positioned below the first support surface, and the third tray does not overlap with the first support surface in a state that the second tray is in the second position.

A transport device includes a body unit, an accommodating unit that accommodates a recording medium and is mounted to be reciprocal with respect to the body unit, a pair of guide members that come in contact with end portions, in a width direction, of the recording medium to position the recording medium, the width direction intersecting with a transport direction of the recording medium, a first rail that is attached to the accommodating unit and guides reciprocation of the accommodating unit, and a second rail that is attached to the body unit to be movable in a direction, which intersects with a reciprocation direction of the accommodating unit, the second rail being assembled to the body unit to be slidable with respect to the first rail.

A transport device including: a body unit including a first cover member attached thereto to cover one side portion of an opening formed at one surface of the body unit, an accommodating unit including a second cover member attached thereto to cover the opening, the accommodating unit configured to accommodate a recording medium, the accommodating unit being reciprocally mounted with respect to the opening of the body unit, and a guide member provided on a bottom surface of the accommodating unit, the guide member configured to guide the accommodating unit so that when the accommodating unit is mounted in the body unit, while being fitted to a positioning pin provided in the body unit, the guide member is positioned so that the second cover member has a gap with the first cover member at a position where the accommodating unit is mounted in the body unit.

The present invention relates to a conveyor system (30) for transporting blanks (2) in a converting machine (1). The conveyor system comprises an endless first conveyor belt (32a) and a support structure (38). The support structure (38) comprising a plurality of rollers (56), each roller being attached to a roller frame (54) and arranged in a line, the roller frames being connected to each other by a connection mechanism (62). The connection mechanism (62) is extendable and retractable in the direction of transportation, such that a contact length (Lc) of the first conveyor belt is modified and all rollers remain in contact with the first conveyor belt.

Provided is a sheet feeding device including: a cassette housing section; a sheet storage cassette; and a sheet feeding unit. The sheet storage cassette includes a cassette base which is configured to store recording media that have a sheet form, and can be inserted into and removed from the cassette housing section. The sheet feeding unit is provided in the cassette housing section, and is configured to feed the recording media to be stored in the sheet storage cassette. A pair of fixed-side rails that are made of metal and are attached to the cassette housing section. The cassette base is made of a resin. A pair of inner rails that are coupled to the pair of fixed-side rails so that the pair of inner rails are slidable are formed integrally with side surfaces of the cassette base.

A system of mitigating force in a mechanical system, the system comprising a frame member, a first rail connected to the frame member, a second rail connected to the frame member and extending along the frame member in parallel to the first rail, an assembly movably engaging the first and second rails, and a first bracket located between the first and second rails, with at least one first bracket attachment secured to the frame member, the first bracket sharing an upper edge with a lower edge of the first rail, such that a downward force applied on the first rail is distributed to the first bracket and the frame member via the at least one first bracket attachment.

A sheet conveying apparatus, including: a base body having a conveyor surface; a separating roller configured to rotate about a first rotation axis parallel to a width direction of the conveyor surface and to convey a sheet downstream in a conveyance direction orthogonal to the width direction; a separating piece opposed to the separating roller and configured to cooperate with the separating roller to separate sheets being conveyed one by one; an attachment member removably attached to the base body at a position at which the attachment member is opposed to the separating roller, so as to form a part of the conveyor surface; a holder holding the separating piece and supported by the attachment member so as to be movable toward and away from the separating roller; and a first urging member provided between the attachment member and the holder for urging the separating piece toward the separating roller.

There is provided a sheet tray including: first, second and third trays. The second tray moves between a first position and a second position in which an overlapping area is smaller than that obtained in the first position. The third tray includes a third support surface and a fourth support surface. The third support surface includes a protrusion which protrudes upward to be positioned above the first support surface in a state that the third tray is in the first pivoting position. The third tray overlaps with the first support surface in a state that the second tray is in the first position and that at least a part, of the third tray, except for the protrusion is positioned below the first support surface, and the third tray does not overlap with the first support surface in a state that the second tray is in the second position.

Provided is a sheet stacking tray such that damage due to external force can be suppressed. The sheet stacking tray (30) is provided with a tray body (40), a first slide member (50), and a second slide member (60). When the first slide member and the second slide member are pulled out, the engagement between a first storage catch portion (44) of the tray body and a first latch portion (52) of the first slide member is released, and then the engagement between a second storage catch portion (54) of the first slide member and a second latch portion (62) of the second slide member is released.
