摘要： An image reading apparatus includes a first unit, a second unit that is pivotable against the first unit, and a controller. The first unit includes a platen, a member, and a movable first reader. The second unit includes an original tray, a conveyance unit that conveys an original from the original tray, a static second reader. The controller determines an opening/closing state of the second unit against the first unit based on read data obtained when the second reader reads the member. The first reader reads the first side of an original conveyed by the conveyance unit and the second reader reads the second side of the original when the original placed on the original tray is read. The first reader reads the first side while moving under the original when the original placed on the platen is read.

摘要： An original reader capable of being downsized without requiring a large-capacity image memory. A conveying path conveys an original. Sensors are arranged on the conveying path, for detecting the conveyed original. CCD line sensors read the conveyed original. A CPU of the image reader decides the size of the conveyed original based on the results of detection by the sensors. An image memory stores image data output from the line sensors. The CPU transmits the decided original size and the stored image data to a controller. When the CPU cannot decide the original size at a predetermined timing, it transmits one of original size candidates to the controller, as a provisional original size. When the size of the original decided afterwards is different from the provisional original size, the CPU retransmits the decided size of the original.

摘要： An image reading apparatus includes a detection unit provided at a position separated from a positioning portion by a predetermined distance in a first direction, a discriminator configured to determine a length, in the first direction, of a document, and a setting unit that sets a start position to a first position if a detection position at which the detection unit detects the document is not included in a range, in a second direction, of the transparent member that is covered by the document, and sets the start position to a second position if the detection position is included in the range and the detection unit does not detect the document, wherein, in the first direction, the distance between the first position and the positioning portion is larger than the distance between the second position and the positioning portion.

摘要： An image forming apparatus which is capable of reading an original, temporarily storing image data in a storage unit, and then transferring the image data to an image forming unit to improve FCOT in forming an image. A memory stores image data output from image reading units. An image forming unit forms an image on a recording medium based on the image data stored in the memory. A first memory output frequency in a first mode in which one side of an original is read and an image is formed on one side of a recording medium is lower than a second memory output frequency in a second mode in which both sides of an original are read and an image is formed both sides of a recording medium.
