A sheet tray provided with first and second trays respectively having first and second supporting surfaces. The second tray slidably assembled, in a first direction, to the first tray. The first and second supporting surfaces are configured to support sheets thereon. The first tray and the second tray have a first guide portion and a second guide portion which are formed at central parts, in a second direction perpendicular to the first direction, respectively. The second guide portion is configured to slidably contact the first guide portion to guide the slide movement of the second tray. A first separation regulating part formed on the first guide portion, and a second separation regulating part formed on the second guide portion are configured to engage with each other in the vertical direction to prevent separation of the first and second trays in the vertical direction, exceeding a particular dimension.

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.

It is described a winding apparatus for wrapping a material around a core of flat shape that rotates around a rotation axis rotating in its turn with a circular trajectory, controlling the laws of motion both of the core rotation around its axis and of the circular trajectory of its rotation axis, motor driven independently by means of electric cams, such as to cancel the variations of position and speed of the material at the entrance of the core The winding apparatus is used for producing electric energy accumulating devices.

The apparatus for processing flat objects includes a transport system with several rotatably mounted conveyor rollers, the flat objects transportable in the direction of transport, and at least one releasably mounted tool module releasably coupled to only one drive shaft or to a lower and an upper rotatably mounted drive shaft; is supported displaceable along the only one drive shaft or the lower and the upper drive shaft; and is equipped with tool parts for processing the flat objects, of which at least one is drivable by the lower or the upper drive shaft. The tool module is supported by a tool carrier which is displaceable by means of a rotatably mounted setting shaft in parallel to the only one drive shaft and to the lower and the upper drive shafts, and which tool carrier has at least one holding element which serves for releasably holding the tool module.

There is provided a sheet tray including: a first tray; a second tray supported by the first tray; and a third tray supported by the second tray. The second tray has a first engaging section engageable with the first tray at a second position; the third tray has a second engaging section contactable with the second tray, in a drawing direction from a first position toward the second position, at a fifth position between a third and a fourth position, and engageable with the second tray at the fourth position. The second engaging section is configured to be elastically deformable to be movable in a releasing direction in which the contact between the second engaging section and the second tray is released. The second and third trays are moved integrally in the drawing direction in a state that the second engaging section makes contact with the second tray.

Disclosed is a sheet stacking apparatus which includes a first stacking portion on which a sheet is stacked, a second stacking portion which is movable with respect to the first stacking portion, a third stacking portion which is detachably attachable to the first stacking portion or the second stacking portion and a restricting portion which restricts disengagement of the third stacking portion which has been attached. The second stacking portion is movable such that the second stacking portion is located at a first position where the restricting portion does not restrict disengagement of the third stacking portion and a second position where the restricting portion restricts disengagement of the third stacking portion which has been attached.

A feeding tray includes a first member supported, via a housing member, by a main body of a recording device configured to perform recording onto a medium, and a second member that includes a second support surface configured to support the medium and is coupled to the first member to be movable relatively to the first member, with a transport direction of the medium being a movement direction. The second member includes a second frame body forming an outer peripheral portion of the second member, and a plurality of second ribs spanning across the second frame body to form the second support surface.

A medium discharging apparatus includes a first tray in which a medium is received and placed, a second tray in which a medium discharged from the first tray is received, a discharging mechanism that discharges the medium from the first tray toward the second tray, and a first curl suppressing member that is located above a rear end region of the medium in the discharge direction and that moves so as to follow movement of the rear end region while maintaining an attitude of the medium until the medium placed on the first tray is discharged from the first tray to the second tray by the discharging mechanism and placed on the second tray.

A medium ejecting apparatus includes medium ejecting apparatus includes an ejection roller to eject a medium, a tray to load the medium ejected by the ejection roller, a medium regulating member provided with a load pressing portion on a front-end side thereof to apply a load to the medium ejected on the tray, and provided with an engaging portion on a base portion side opposite to the front-end portion, and a holding member provided with an engaged portion to engage with the engaging portion, to hold the medium regulating member in such a way that the medium regulating member can swing in a vertical direction with respect to an upper surface of the tray, and pivot along a rotation axis in a direction from the base side toward the front-end portion side, according to the ejection of the medium.

A roll feed includes a base body, a first tube roll having a rolling surface and a first bearing shaft, wherein the base body is configured to support the first tube roll and the first bearing shaft. The first bearing shaft and the first tube roll are configured to be detachably connected to each other for a rotationally fixed connection, wherein the base body is configured such that the first tube roll can be removed from the base body in an axial direction, wherein the axial direction is substantially parallel to an axis of rotation of the first tube roll.
