An example print medium supplying apparatus includes a print medium transporting device to pick up a print medium loaded in a loading portion and transport the picked-up print medium, a print medium alignment portion to align a leading end of the transported print medium, a first sensor to sense the print medium that passes through a feed roller of the print medium transporting device, and a processor to, based on a measured value with respect to the print medium sensed by the first sensor and a multi-feeding determination reference value corresponding to a sheet of the print medium, detect multi-feeding of the print medium and process the detected multi-feeding by controlling the print medium transporting device and the print medium alignment portion.

A medium conveying apparatus includes a conveying roller to convey a rectangular medium, and a processor to generate an input image acquired by imaging the conveyed medium, detect an overlap of the conveyed medium, detect an object area from the input image, determine whether an outer shape of the object area is rectangular, determine whether a multi-feed of the medium has occurred based on whether the overlap of the medium has been detected and whether the outer shape of the object area is rectangular, and execute an abnormality processing when it is determined that the multi-feed of the medium has occurred.

A medium conveying apparatus includes a pick roller feeding a medium, a separation roller placed on a downstream side of the pick roller in a conveying direction of a medium, an arrival detection sensor placed on a downstream side of the separation roller in the conveying direction and detecting arrival of a medium, a lift sensor detecting a lift of a medium between an upstream side of a roller nip of the pick roller and a downstream side of a roller nip of the separation roller, and a processor. The processor determines that a medium is a bound medium when a lift of a medium is detected by the lift sensor in a first predetermined period after detection of a front edge of a medium in a conveying direction by the arrival detection sensor, and executes abnormality processing when a medium is determined to be a bound medium.

A sheet feeding apparatus can perform appropriate separation corresponding to the type of sheet without an actuator which changes the separation action of a separation unit. For this purpose, a separation unit includes a first inclined part and a second inclined part, each having different inclination angles, and selects, in accordance with the type (stiffness, thickness, or the like) of sheet to be fed, either one of the first inclined part or the second inclined part as an inclined part used in separating sheets by lifting/lowering a tray, and separates sheets, so that appropriate separation can be performed in accordance with the type of sheet with a simple configuration.

A tiltenator of a media separator module (integrated within a valuable media depository) adaptively controls pressure maintained against a bunch of media as individual items from the bunch are fed through the media separator module.

A single material sheet is picked from a support member. A gripping member is aligned above the support member, where the gripping member includes a pair of spaced apart pinching members movably coupled with a main frame, and each pinching member includes an exposed gripping surface that is substantially planar and that faces an exposed surface of the material sheet. The gripping member is moved a first distance toward the exposed surface of the material sheet such that the gripping surfaces of the pinching members engage a portion of the material sheet. The pinching members for the gripping member are moved toward each other while the pinching members engage the portion of the material sheet so as to pinch the portion of the material sheet between the pinching members and vertically displace the material sheet from the support member.
