Techniques for determination of size of printable medium are described. In an example, a printing device includes an adjuster that is movable based on a size of a printable medium to be fed to the printing device. A first element is coupled to the adjuster and moves with the adjuster to indicate a position of the adjuster. A second element is movable relative to the adjuster. A position signal indicative of a distance between the second element and the first element is generated. The position signal can be used to determine the size of the printable medium.

A feeder device for feeding a stack of value documents to a singler device, and is configured to withdraw individual value documents from the stack. The feeder device includes a stop element having front and back sides; two lateral guide elements provided at the front side of the stop element and configured to guide the stack at two lateral sides of the stack towards the singler device; two support elements, on which the lateral guide elements are mounted; and two or more bearing elements by which the support elements are movably mounted on the stop element to allow the respective positions of the lateral guide elements and/or the distance of the lateral guide elements relative to each other to be changed. The invention further relates to an according method, a singler device, a singler module and a system for processing value documents.

An image reading apparatus includes a stacking portion, a feeding unit, a reading unit, and a discharge portion provided below the stacking portion. The feeding unit feeds a sheet stacked on the stacking portion in a feeding direction. The reading unit reads an image on the fed sheet and the discharge portion discharges the read sheet. The stacking portion includes first and second support surfaces that support the sheet and first and second regulating units to regulate a position of the sheet in a widthwise direction using two opposing ends of the sheet. The second support surface is retractable from a predetermined section above the discharge portion. The first support surface includes a downstream support portion that supports the sheet on a downstream side of the predetermined section in the feeding direction. A part of the second regulating surface is positioned on the downstream support portion.

A sheet separation device separates a non-bonding portion of a two-ply sheet in which two sheets are overlapped and bonded together at one end of the two-ply sheet. The sheet separation device includes a separator that includes a first separator and a second separator. The first separator is inserted into a gap between the two sheets of the two-ply sheet. The second separator is inserted between the two sheets at said another end of the two-ply sheet that is opposite to the one end of the two-ply sheet and moves in a width direction of the two-ply sheet after the first separator is inserted into the gap and relatively moves from the one end to said another end.

There is provided a sheet storage device including a regulation unit that includes a first contact portion configured to contact a stacking unit, and a second contact portion configured to contact a facing member. The first contact portion contacts the stacking unit in a state of being urged toward the stacking unit. The second contact portion contacts the facing member in a state of being urged toward the facing member.

A sheet supporting apparatus includes a positioning device to position a regulating portion to a sheet support. The positioning device includes a first group of teeth provided on the sheet support, a second group of teeth disposed at a position different from the first group of teeth provided on the sheet support, a third group of teeth provided on a regulator and capable of transiting to a first state of engaging with the first group of teeth and to a second state of engaging with less area of the first group of teeth than that in the first state, and a fourth group of teeth provided on the regulator and capable of transiting to a third state of engaging with the second group of teeth and to a fourth state of engaging with less area of the second group of teeth than that in the third state.

A sheet separation device separates a non-bonding portion of a two-ply sheet in which two sheets are overlapped and bonded together at one end of the two-ply sheet. The sheet separation device includes a separator that includes a first separator and a second separator. The first separator is inserted into a gap between the two sheets of the two-ply sheet. The second separator is inserted between the two sheets at said another end of the two-ply sheet that is opposite to the one end of the two-ply sheet and moves in a width direction of the two-ply sheet after the first separator is inserted into the gap and relatively moves from the one end to said another end.

A sheet feeding apparatus includes a supporting portion to support a sheet, a feeding portion to feed the supported sheet, and a base member opposed to the supporting portion so the sheet is supported by the supporting portion between the supporting portion and the base member. A regulation unit includes a regulation portion to regulate a position of an edge portion of the supported sheet and moves in a moving direction, and a sensor outputs an output value that changes in accordance with an amount of movement of the regulation unit. The sensor and the regulation unit are supported by the base member, and the sensor is supported by the base member at a position above an abutment position between the sheet supported by the supporting portion and the feeding portion in a gravity direction.

A medium placing device (feeding tray) includes a placement unit, a regulation unit (edge guide), a displacement unit, a detection unit, and an adjustment unit. The regulation unit (edge guide) includes a first regulation member (first edge guide) and a second regulation member (second edge guide). The displacement unit is capable of moving the first regulation member (first edge guide) and the second regulation member (second edge guide) in directions opposite to each other along a first direction. The detection unit is provided between the placement unit and the adjustment unit.

A sheet storage apparatus attached to an apparatus body in an attaching direction includes a sheet storage portion configured to store a sheet, a moving unit movably supported by the sheet storage portion in a moving direction parallel to the attaching direction, wherein the moving unit includes a regulation member and an extending member extending in the moving direction, the regulation member including a regulation surface regulating a position, in the moving direction, of the sheet stored in the sheet storage portion, and a first bonding surface extending along the moving direction, the extending member including a second bonding surface extending parallel to the first bonding surface, and wherein the first bonding surface and the second bonding surface are configured to be bonded to each other by adhesive.
