A bill processing apparatus which is capable of reliably supplying information on a bill to the bill housing body side. The paper sheet processing apparatus has a bill housing part being capable of housing a bill inserted from a bill insertion slot, and also a reader/writer which wirelessly transmits information on the bill inserted from the bill insertion slot. The bill housing part has a coil antenna which wirelessly receives the information transmitted from the reader/writer, and a storage part which stores the information on the bill received from the coil antenna.

This disclosure relates to a method and apparatus for taking flexible sheets off a delivery belt, such as from a scanner or copier, and restacking them in the order and orientation (face) they were originally scanned in. This requires flipping over such sheets by use of a spindle wheel with a plurality of fingers defining slots therebetween for receiving the sheets and reversing their face (flipping). By knowing the speed of the delivery belt and using a continuously spinning spindle wheel it is possible to avoid the effects of momentum on the fingers which distorts their position during stopping and starting action. Instead, the spindle wheel is in constant rotation but the speed of rotation is adjusted from a first speed, then a second tapering speed, to a third speed which is adapted to ensure that the slot between fingers is accurately presented to the leading edge as it enters the slot and does not get rejected by an accidental encounter with a finger.

An image forming apparatus includes a conveyor, an actuator, an image forming unit, a detection unit, and a controller. The conveyor transports a sheet having a length measured in a transport direction. The actuator drives the conveyor. The image forming unit forms an image on the sheet. The detection unit includes a first sheet detection sensor that outputs a detection signal indicating whether the sheet transported by the conveyor passes through a first predetermined detection position. The controller controls the actuator based on the length of the sheet in response to an indication that the detection unit is not operating normally.

An image recording apparatus including: a recording unit; an accommodation part configured to accommodate therein a plurality of recording media including first and second recording medium and having a support surface on which the plurality of the recording media is supported; a conveying path; a feeder roller contacting the recording medium in the accommodation part from above; a reversing path; a recording medium detection unit located above the support surface and between the feeder roller and a downstream end of the support surface in the conveying direction; and a controller configured to control the feeder roller so as to feed the second recording medium in a manner that a front end portion of the second recording medium overlaps a rear end portion of the first recording medium, when the recording medium detection unit detects the rear end portion of the first recording medium fed by the feeder roller.

An image forming apparatus has a sheet feed portion, a conveying portion, a control portion, a first sensor having the detection position at a first position in the sheet conveying passage, and a second sensor having the detection position at a second position downstream of the first position in the sheet conveying direction. The control portion performs first sensing to sense whether the sheet's rear end has passed the first position within a first time of the start of the feeding and second sensing to sense whether the sheet's rear end has passed the second position within a second time of the start of the feeding. Even if the control portion is unable to sense passage of the sheet's rear end in the first sensing, when it senses passage of the sheet's rear end in the second sensing, it makes the conveying portion continue feeding the sheet.

A sheet conveyer, having a sheet tray, a tray-driving mechanism, a conveyance guide, a feed roller, a conveyer-driving mechanism, a first sensor, and a controller, is provided. The controller controls the tray-driving mechanism and the conveyer-driving mechanism, during a sequential conveying action, when the first sensor detects an upper-surface level being at a lower limit of a correct range, delay a lift-start timing, at which the tray-driving mechanism starts moving the sheet tray upward, to be later at least than a timing, at which the feed roller after feeding one of the sheets completely and pausing resumes rotating for feeding a next one of the sheets, and cause the sheet tray to complete moving to a higher position prior to completion of feeding of the next sheet.

A post-processing device includes a transport path along which a medium printed with liquid ejected by a liquid ejecting portion is transported, an intermediate tray on which the medium is stacked, a first transporting member starting a first transporting operation of transporting the medium upstream in a transport direction after a rear end of the medium passes through the transport path, a rear-end alignment portion that comes into contact with the rear end of the medium transported by the first transporting member and that aligns the medium, a control portion controlling an operation of the first transporting member, and a detection portion detecting a transporting state of the medium in the intermediate tray, in which when the control portion determines, from an output of the detection portion, that the medium reaches the rear-end alignment portion, the control portion regulates the first transporting operation of the first transporting member.

A sensor assembly configured to detect rolled stock on a core includes a sensor configured to detect a first roll of stock unwinding from a core, the stock unwinding from the core of the first roll is supplied as a web of stock, wherein in response to the sensor detecting a first detection configuration, the sensor takes no action and continues to detect the first roll, and wherein in response to the sensor detecting a second detection configuration, the sensor provides a command to a splice assembly to transition to a second roll of stock to replace the first roll of stock.

A bill processing apparatus which is capable of reliably supplying information on a bill to the bill housing body side. The paper sheet processing apparatus has a bill housing part (100) being capable of housing a bill inserted from a bill insertion slot, and also a reader/writer (142) which wirelessly transmits information on the bill inserted from the bill insertion slot. The bill housing part (100) has a coil antenna (104c) which wirelessly receives the information transmitted from the reader/writer (142), and a storage part (104b) which stores the information on the bill received from the coil antenna (104c).
