In a scanner, a medium transport apparatus includes an apparatus main body including a medium transport path from a supply unit, which supplies a medium, to a discharge unit, which discharges the medium, a switcher that switches an attitude of the apparatus main body with respect to a mounting surface on which the apparatus main body is mounted, and a controller that, when the attitude of the apparatus main body with respect to the mounting surface is switched, performs control in accordance with the attitude after the switching.

Medium transport apparatus and image reading apparatus

When a transport section transports be a media, a controller of an image reading apparatus determines the lengths of the media in the transport direction, based on detection results of a medium detector. When determining that a length of a medium is equal to or more than a threshold and then determining that a length of a subsequent medium is equal to or more than the threshold, the controller decreases an ejection speed of the subsequent medium to a second speed by the transport section. When determining that a length of a medium is equal to or more than the threshold and then determining that a length of a subsequent medium is less than the threshold, the controller decreases the ejection speed from the first speed to a third speed that is lower than the second speed by the transport section.

Image reading apparatus using plurality of media having different length

A reading apparatus includes a transport unit, a multi-feed detection unit, a reading unit, and a controller. When a multi-feed of the document is detected by the multi-feed detection unit, the controller multi-feeds causes the transport unit to discharge, downstream of the transport path, a multi-fed document for which the multi-feed is detected and then temporarily stops the transport, stores multi-fed page information indicating a page number of the multi-fed document, restarts the transport after the temporary stop, and after the reading unit reads a remaining document whose page succeeds a page of the multi-fed document, performs a re-reading process including the transporting and the reading of the multi-fed document, respectively, and inserts, based on the multi-fed page information, second read data acquired by the reading in the re-reading process into first read data acquired by the reading completed before the re-reading process.

Reading apparatus and reading control method

An image reading apparatus includes a reading unit, a transport unit that transport a document, a feeding unit that transports the document to the transport unit, a controller that stops the feeding operation of the feeding unit after the leading end of the preceding document transported from the feeding unit reaches the transport unit and restarts the feeding operation after the rear end of the preceding document passes a predetermined position. The controller, restarts the feeding operation a first time after the rear end of the succeeding document following the preceding document passes the predetermined position when a size of the preceding document indicates a first size, and restarts the feeding operation a second time after the rear end of the succeeding document passes the predetermined position where the second time is longer than the first time when the size indicates a second size larger than the first size.

Image reading apparatus and control method thereof

A reading apparatus includes a transport unit that transports a document along a transport path, a multi feed detection unit that detects multi feed for a transport document that is the document being transported by the transport unit, a reading unit that reads the transported document, and a controller that controls the transport unit, wherein the controller acquires a multi feed length that is a length of a range in which multi feed occurs in the transported document according to a detection result of multi feed by the multi feed detection unit, causes the transport unit to stop transport of a document following the transport document by when the multi feed length is equal to or greater than a predetermined threshold value for the multi feed length, and causes the transport unit to perform transport of the following document when the multi feed length is less than the threshold value.

Reading apparatus and multi feed detection method

A transporting apparatus (for example, image reading apparatus) includes a transporting mechanism that transports a document along a transporting path and a processing unit that determines an inclination error of the document. The processing unit determines whether or not the inclination error has occurred in accordance with a document size and a tilt angle of the document.

Transporting apparatus, program, and control method of transporting apparatus

In a continuous mode, when a state in which a current value, which is output of a load detecting sensor, is equal to or more than a predetermined threshold (a current value) continues for a predetermined threshold (the number of times), it is determined that transportation is abnormal. In a cumulative mode, when the total number of times by which the current value, which is the output of the load detecting sensor, is equal to or more than the predetermined threshold (the current value) is equal to or more than a predetermined threshold, it is determined that the transportation is abnormal. A controller sets a detection mode of a first medium to the continuous mode, and sets a detection mode of a second medium to the cumulative mode.

Transport apparatus

When consecutively feeding a plurality of media, an image scanning apparatus, according to the length of a preceding medium in a feed direction, changes the feed control for feeding the succeeding medium.

Image scanning apparatus

In a case in which a carrier sheet including transparent sheet portions of two pieces which can interpose a document therebetween, and a bonding portion which bonds sheet portions to each other is transported in a state in which the bonding portion is located on the downstream side in the transport direction, a reading unit is caused to start reading, after an upstream end of the bonding portion passed through the reading unit.

Image reading apparatus and image reading method

A feed detection unit which detects a document which is fed is provided at a position between a pinching position at which a feed roller and a frictional force application portion pinch the document and an intersecting position at which a tangential line of the feed roller which is closer to a downstream side in a transport direction than the pinching position is perpendicular to a transport path in the transport direction, which is a different position from the feed roller in a width direction which intersects the transport direction.

Image reading apparatus

An image reading apparatus is configured to read an image of each of documents transported in a transport path from an upstream side to a downstream side in a transport direction, acquires a correction factor for correcting a read image on the basis of a fed document number, and corrects the length of the read image in the transport direction on the basis of the correction factor which has been acquired.
