A banknote feeder device (3) configured to interconnect and operate in conjunction with a banknote acceptor apparatus (2), the banknote feeder device (3) comprising a banknote transport mechanism operable, when the banknote feeder device (3) is connected to the banknote acceptor apparatus (2), to transport a banknote from a banknote input aperture to a banknote output aperture. The banknote transport mechanism comprises a linear succession of spaced-apart pairs of transport wheels (22) and each transport wheel extends at least partially through a banknote transport conduit surface into an interior cavity of the banknote transport conduit between the banknote input aperture and the banknote output aperture.

An image reading apparatus includes a document tray, a common transport route, a curved transport route, a linear transport route, a switching device, a document transport device, a first image sensor, a second image sensor, a trailing edge detector, a multi feed detector, a leading edge detector, and a controller. The controller determines a length of the document in the transport direction, on a basis of a time point that the leading edge detector has detected the leading edge of the document, a time point that the trailing edge detector has detected the trailing edge of the document, and a time point that a detection status of the multi feed detector has been switched to a non-detection state, and guides the document to the curved transport route or the linear transport route from the common transport route, according to the length of the document, by controlling the switching device.

A suction fan of a sheet feeder sucks in air through a sheet feeding belt to generate flotation air. The suction fan uses the flotation air to attract set sheets by suction. A belt motor rotates a sheet feeding belt and feeds out a sheet of the set sheets. An interval measurer measures a sheet-to-sheet interval when the suction fan is attracting the sheet by suction. Based on an output of the interval measurer, a controller recognizes the sheet-to-sheet interval. Based on the recognized sheet-to-sheet interval, the controller adjusts a flow rate of the flotation air.

A blanks storage unit for storing a stack of blanks includes: inlet and outlet sections of the blanks; a feed device having a support device to restingly receive the blanks of the stack of blanks; and a feed element for moving the blanks along a feed trajectory from the inlet section towards the outlet section. The unit also includes a guide device. At least one of the support device or the guide device is movable with respect to the other along a lifting trajectory between a transport configuration, in which said support device defines in the section a feed plane of the blanks and the blanks rest on the support device, and a sliding configuration in which the guide device is at least partially lifted with respect to the support device and the blanks rest on the guide device to be guided, sliding along the section towards the outlet.

The control section of the recording device can execute a power switching step of moving the carriage based on the reference movement amount M, a retry step of performing the power switching step with an amount obtained by subtracting an adjustment amount ma from the reference movement amount M after the adjustment as a reference movement amount M when the power transmission section is not switched from the power non-transmission state to the power transmission state as a result of the power switching step, and a reference movement amount correction step of holding an amount obtained by subtracting the adjustment amount mc from the reference movement amount M after the adjustment as a new reference movement amount M when the power transmission section is switched from the power non-transmission state to the power transmission state as a result of the retry step.
