摘要： A media ejecting apparatus includes a conveyance roller, an ejection roller, and circuitry. The conveyance roller conveys a first medium and a second medium following the first medium. The ejection roller ejects the first medium and the second medium. The circuitry reduces a first ejection speed at which the ejection roller ejects the first medium. The circuitry determines a first skew of the first medium and a second skew of the second medium, and changes at least one of a reference for determining whether to reduce the first ejection speed, when to reduce the first ejection speed, a conveyance speed at which the conveyance roller conveys the second medium, or a time during which the conveyance roller stops conveying the second medium, based on the first skew or the second skew.

摘要： A media feeding apparatus includes: a feed roller, a separation roller, and a pressing portion to press one of the feed roller and the separation roller against the other to form a nip region. A surface of the feed roller has grooves extending in a width direction of the feed roller. The grooves are arranged with a pitch such that at least one groove is always present in the nip region during feeding of the medium. A width of each groove is 0.5 mm or greater and is set such that a contact area ratio is 0.5 or greater, the ratio being a value obtained by {(a surface area of the feed roller in the nip region−an area of the at least one groove of the feed roller in the nip region)}/(the surface area of the feed roller in the nip region). A surface of the separation roller has grooves extending in a circumferential direction of the separation roller.

摘要： A medium conveying apparatus includes a conveyance roller to convey a medium, a DC motor to drive the conveyance roller, a processor to rotate the DC motor, an encoder to output a first pulse signal whose cycle varies according to a rotation speed of the DC motor, and an imaging device to acquire an image acquired by imaging a conveyed medium in response to a pulse of a second pulse signal whose cycle is constant. The processor detects a number of pulses of the second pulse signal included in a predetermined cycle of the first pulse signal, and discards images acquired by the imaging device in the same number of pulses as difference between the detected number of pulses and a reference number, in a next cycle of the predetermined cycle of the first pulse signal, when the detected number of pulses exceeds the reference number.

摘要： An information processing system includes circuitry. The circuitry performs image processing on an image to generate a processed image. The circuitry acquires a correct character string for a text area in the processed image. The circuitry acquires a recognized character string by performing character recognition on the text area in the processed image. The circuitry performs collation between the correct character string and the recognized character string. The circuitry displays one or more windows reflecting a result of the collation between the correct character string and the recognized character string on a display for allowing a user to evaluate whether the image processing is suitable for character recognition. The circuitry controls a displaying manner of at least one window of the one or more windows to vary according to the result of the collation.

摘要： A medium conveyance apparatus includes a housing having a frame, a placing table provided on the housing to be openable and closeable and configured to place a medium when the placing table is in an opened state, a to-be-engaged portion provided on the frame, an engagement part provided on at least one side of the placing table to face the to-be-engaged portion when the placing table is in a closed state, a to-be-contacted portion provided on the frame, and a contact portion provided on the placing table. In the medium conveyance apparatus, when the placing table is in the closed state, the engagement part engages with the to-be-engaged portion and maintains the closed state of the placing table. In the medium conveyance apparatus, when the placing table is in the closed state, the contact portion contacts the to-be-contacted portion and restricts movement of the placing table and thereby restricting separation of the engagement part from the to-be-engaged portion.
