In addition, the main board may be provided in an orientation along the document transport path.

An image reading apparatus includes an image sensor, a document feeder, and a processor. The document feeder includes a first driving device, a second driving device, a third driving device, a first sensor, and a second sensor. The first driving device includes a pick-up member to move documents from a tray to a document conveying path using a driving force through a first clutch. The second driving device is to move the tray with the documents to a side of the pick-up member using a driving force through a second clutch. The third driving device to move the documents along the document conveying path onto the image sensor using the driving force of the motor The first and second sensors detect the documents on the document conveying path. The processor controls an operation of the first clutch based on the signals of the first and second sensors.

An image reading apparatus includes a supply tray which support sheets and includes a movable plate configured to move in correspondence to reduction in a number of the sheets supported on the supply tray, a discharge tray which is located below the supply tray and supports discharged sheets, a conveyance guide which guides a sheet conveyed from the supply tray toward the discharge tray, a reading sensor which reads an image on the sheet conveyed along the conveyance guide, and a discharge unit having a discharge opening for discharging the sheet to the discharge tray and moves from a third position to a fourth position in correspondence to reduction in the number of the sheets supported on the supply tray. A first timing for which the movable plate is to move and a second timing for which the discharge unit is to move are different.

A scanning device includes an outer shell, a glass platform, a contact image sensor, a paper feeding unit and an upper cover. An inside of the outer shell has an accommodating space. The glass platform is disposed to the outer shell. The glass platform includes an automatic paper fed and scanned area, and a static paper scan area. The contact image sensor is disposed in the accommodating space. The paper feeding unit is disposed to a top surface of the automatic paper fed and scanned area. The upper cover is pivotally disposed to a top surface of the static paper scan area. A top surface of the upper cover is recessed downward to form a paper loading groove.

An image reading apparatus includes a first medium support section, a casing, a reading unit, and a posture switching section. The first medium support section supports a medium to be fed. The casing includes a reading unit that performs reading on the medium fed from the first medium support section. The reading unit performs reading on the medium fed from the medium support section. The posture switching section is configured to switch between a first posture in which the casing is inclined obliquely and a second posture in which the casing is inclined with respect to a horizontal direction more than in the first posture. An upper face of the casing is configured to be utilized as a second medium support section that is configured to mount the medium when the casing is in the second posture.

A recording apparatus includes: an apparatus main body having a recording unit that performs recording onto a recording medium; and a document reading mechanism unit having a reading unit that reads a document and a document transport unit that transports a document to the reading unit, the document reading mechanism unit being provided in an upper part of the apparatus main body, wherein the apparatus main body includes: a feed roller that feeds the recording medium toward the front of the apparatus; and a frame having a frame surface intersecting the horizontal direction, the frame being located between the feed roller and the recording unit in an apparatus depth direction, and a part of the document reading mechanism unit overlaps the feed roller in the apparatus depth direction, and overlaps the frame in the vertical direction.

An image recording apparatus, including: a housing; an image recording portion held by the housing; a control board having a mounting face and disposed in the housing such that the mounting face extends along a perpendicular plane perpendicular to a height direction, a control circuit for controlling the image recording portion being provided on the control board; and a communication board having a mounting face and disposed in the housing such that the mounting face extends along the perpendicular plane, such that the communication board is distant from the control board in a direction along the perpendicular plane, and such that the communication board is located within a height range ranging to the control board from a distal end of a highest one of mounted components mounted on the control board, an interface circuit to be connected to a telephone line being provided on the communication board.

An image reading device comprises a document table having a plate-shaped transparent member for a document to be placed thereon, an image reading unit for reading the document placed on the upper surface of the transparent member from the lower surface side of the transparent member, a carriage for driving the image reading unit to move reciprocally, and a case for containing the carriage. The document table has a frame member along a periphery of the transparent member and is secured to the case by engagement right under the frame member.

There is provided a medium transport device including a placement section on which a medium is placed, a transport path through which the medium is transported, a feeding roller that feeds the medium, a set guide configured to switch between a contact position where the medium and the feeding roller are brought into contact and a separation position where the medium and the feeding roller are separated, a restricting section configured to switch between a restricting position for restricting feeding of the medium by coming into contact with a leading end of the medium and an allowing position for allowing the feeding of the medium, and a drive source that generates power for switching of the set guide and switching of the restricting section. The set guide and the restricting section are provided below the transport path in a direction of gravity.

A printer that improves user convenience for rotating collation printing is provided. In a printer having a rotating collation function, multiple paper feed ports configured to feed paper, an acquisition unit configured to acquire a user request, and a setting unit configured to enable or disable the rotating collation function, the setting unit sets the rotating collation function to enabled when the acquisition unit acquires a user request to enable the rotating collation function, a first paper of a specified size that is fed in a landscape orientation and a second paper of the specified size that is fed in a portrait orientation are set in multiple paper feed ports, and paper feed port selection is set to automatic.
