Abstract: An image reading apparatus includes a discharging unit that discharges an original document read by a reading unit to a stacker, in which a controller of the image reading apparatus discharges a first original document at a first transporting speed caused when the original document specified from an original document length measured by the measuring unit is the first original document and discharges a second original document at a second transporting speed slower than the first transporting speed caused when the original document is the second original document longer than the first original document.

Abstract: An image reading apparatus includes a roller that transports a document; a reading unit that reads an image of the document which is transported; a DC motor that drives the roller; and a control unit that controls the DC motor. The control unit is configured to stop driving of the DC motor in a case where a driving load value obtained when the DC motor is driven exceeds a threshold. A first threshold which is applied in a case of a first document and a second threshold which is applied in a case of a second document of which a basis weight is larger than a first basis weight are set, and the first threshold is less than the second threshold.

Abstract: An image reading apparatus includes a medium mounting portion configured to mount a medium; a feeding means configured to feed a medium from the medium mounting portion; at least one edge guide each configured to regulate a corresponding one of at least one medium width direction edge of the medium having been mounted on the medium mounting portion; a reading means configured to read the medium and disposed on a further downstream side than the at least one edge guide in the medium feeding direction; and at least one medium detection means configured to detect the medium and disposed on a further downstream side than the at least one edge guide in the medium feeding direction and further outside in the medium width direction than at least one edge regulation position for the edge regulation by the at least one edge guide.

Abstract: An image reading apparatus is provided with a reader which reads a document, a transport roller which is provided on an upstream side of the reader in a document transport path in which the document is transported and transports the document to a reading position of the reader, and a controller which receives reading data of the reader and controls the transport roller, in which the controller receives the reading data from the reader to acquire a form of the document, and selects whether or not to stop driving of the transport roller based on the form.

Abstract: A medium feeder includes a feed roller that feeds a medium loaded on a medium loading section; a transport roller disposed downstream relative to the feed roller; a first driving source that drives at least the feed roller; a second driving source that drives at least the transport roller; and a housing that houses the feed roller, the transport roller, the first driving source, and the second driving source, wherein the housing includes a lower unit that constitutes a lower part of the housing, and an upper unit openable relative to the lower unit, and the first driving source and the second driving source are disposed on both sides relative to a center part of the lower unit in a width direction perpendicular to a medium transportation direction.

Abstract: When a power supply mode is an AC power mode, if a correction value which is read out from a non-volatile memory is a second correction value ?2 corresponding to a battery mode, a first correction value ?1 is calculated according to an equation ?1=?2×K2 using the second correction value ?2, and bidirectional printing is performed by controlling an ejection timing of a print head based on the first correction value ?1. Meanwhile, when a power supply mode is the battery mode, if the correction value is the first correction value ?1 corresponding to the AC power mode, the second correction value ?2 is calculated according to an equation ?2=?1×K1 using the first correction value ?1, and bidirectional printing is performed by controlling the ejection timing of the print head based on the second correction value ?2.
