An image reading device includes a reader, a transparent member, an opposing member, first and second conveyance rotators, and circuitry. The reader reads a sheet. The transparent member is disposed between the reader and the sheet. The opposing member is disposed facing the reader via the transparent member. The first conveyance rotator is disposed upstream from the reader in a conveyance direction of the sheet. The second conveyance rotator is disposed downstream from the reader in the conveyance direction. The circuitry cause the first conveyance rotator and the second conveyance rotator to convey a cleaning sheet at respective conveying speeds different from each other and bring the cleaning sheet into contact with at least one of the transparent member or the opposing member.

An image inspector includes a recording device and circuitry. The reading device is configured to read an image on a recording medium. The circuitry is configured to determine whether the recording medium has a wrinkle and an edge folding based on a plurality of positions on the image on the recording medium read by the reading device satisfying a predetermined relation. The circuitry is configured to determine whether the recording medium has the wrinkle based on the predetermined relation, and then determine whether the recording medium has the edge folding based on the predetermined relation.

Image inspector for detecting at least one abnormality of a recorded medium and image forming system incorporating the image inspector

An image reading device includes an image reader and circuitry. The image reader is configured to read an image on a recording medium. The circuitry is configured to obtain defective image information and defect type information based on the image on the recording medium read by the image reader, and determine an abnormality of the image on the recording medium based on the defective image information and the defect type information.

A reading apparatus includes a reading device and processing circuitry. The reading device reads a recording medium. The processing circuitry outputs maintenance information based on read information read by the reading device.

Reading apparatus and image forming system for outputting maintenance information

A reading apparatus includes a reading device and circuitry. The reading device reads a recording medium in a direction intersecting a conveyance direction of the recording medium. The circuitry detects a reference image for cutting processing of the recording medium, based on read information read by the reading device.

Reading apparatus, processing apparatus, and image forming system configured to correct a reference image detection position

An image inspecting device includes an abnormality detector and circuitry. The abnormality detector is configured to detect an abnormality of an inspection object image. The circuitry is configured to set a non-detection area to be excluded from a detection object area within which the abnormality detector detects an image abnormality and set an area including an abnormality detection portion as the non-detection area when a detection result obtained by the abnormality detector satisfies a non-detection condition.

Image inspecting device and image forming apparatus incorporating the image inspecting device

An image abnormality detecting device includes an image reader, an abnormality detector, a pattern holder, and circuitry. The image reader is configured to read an image on a recording medium. The abnormality detector is configured to detect abnormality of the image based on read information of the image on the recording medium, read by the image reader. The pattern holder has a check pattern and is disposed within a reading area of the image reader. The circuitry is configured to inspect a detecting operation of the abnormality detector based on read information of the check pattern read by the image reader.

An image reading device includes a transparent member unit including a transparent member, an opposing member opposed to the transparent member, and a reading mechanism. The reading mechanism irradiates the opposing member and a medium being conveyed between the transparent member and the opposing member with light through the transparent member and receive reflected light from the opposing member and the medium. The reading mechanism includes a position adjuster to which the transparent member unit is secured and a guide to guide the transparent member unit in a direction intersecting a direction of conveyance of the medium to detachably attach the transparent member unit to the reading mechanism. The position adjuster changes a position at which the transparent member unit is secured with respect to the reading mechanism. The transparent member unit is secured to the position adjuster.

A bill handling apparatus includes a first squeezing unit that performs a first squeezing of a bill in receiving the bill, and a second squeezing unit that performs a second squeezing of the bill after the first squeezing, wherein the first squeezing unit comprises a pair of conveying belts that convey the bill in a predetermined conveying direction in receiving the bill, a distance between both the conveying belts being gradually reduced in a direction of thickness of the bill in the predetermined conveying direction, and the second squeezing unit comprises a pair of rollers disposed at an end part of the first squeezing unit in the predetermined conveying direction.

Bill handling apparatus

A paper sheet receiving/dispensing apparatus includes strip films at least one of which is affixed, on at least one of front and back sides, with marks at intervals of a predetermined pattern in a predetermined shape and in a color different from a color of the strip films, a detection sensor for detecting the marks, and a storage device for storing a table that indicates an association between a roll outer diameter of the strip films wound around a winding drum and driving pulses of a stepping motor. The apparatus calculates the roll outer diameter based on the number of rotations of the winding drum, which is calculated based on detection pulses of the marks, and thicknesses of the strip films and a paper sheet, and controls rotations of the motor with driving pulses read from the table.

Paper sheet receiving/dispensing apparatus

A money input/output apparatus includes a bill accommodation unit, a mount unit, a detection unit, a second storage unit, an instruction reception unit, a conveyance unit, and a control unit. The control unit reads the denomination of the bill from the first storage unit and determines whether or not the read denomination of the bill corresponds to the denomination stored in the second storage unit in association with the mount unit on which mounting of the bill accommodation unit has been detected when the detection unit has detected that the bill accommodation unit has been mounted on the mount unit, starts reception of an instruction to input or output to the bill from the instruction receiving unit and makes the conveyance unit convey the bill in accordance with the instruction when the denominations have been determined to correspond. Thereby, a bill accommodation unit can be used for all denominations.

Money input/output apparatus, replenishing/collecting apparatus, and method of running money input/output apparatus

A conveying direction-switching device is formed by direction-changing drums each having the same hollow cylindrical shape having a length corresponding to a lateral width of paper money bills to be conveyed. The direction-changing drum has first to fourth openings arranged in the outer periphery thereof, in a manner spaced from each other by a rotational angle of 90 degrees, and the rotational angle position thereof is controlled to be a predetermined phase angle. Inside the direction-changing drum, the first opening and the fourth opening are connected by a paper money guide forming a first curved passage, the second opening and the fourth opening are connected by a paper money guide forming a straight passage, and the third opening and the fourth opening are connected by a paper money guide forming a second curved passage.
