An information processing apparatus includes a light emitting unit and a light receiving unit for receiving light output from the light emitting unit, and includes a detection unit for outputting a light reception signal indicating that the light receiving unit has received light from the light emitting unit, a driving signal output unit for outputting a driving signal to the detection unit so that the light emitting unit intermittently outputs light, a detection signal output unit for outputting, based on the output driving signal and the output light reception signal, a detection signal indicating whether an object exists between the light emitting unit and the light receiving unit, and a control unit including an interrupt port to which the output detection signal is input and for returning from a power saving state in response to the detection signal being input to the interrupt port in the power saving state.

An automatic document feeder (300) includes a housing (301), conveyance roller pairs (313 to 317), and a pressure releasing mechanism. The housing (301) is openably/closably attached to a main body of an image forming apparatus. The conveyance roller pairs (313 to 317) pinch an original document sheet with pressure and feed the original document sheet. The pressure releasing mechanism detaches one rollers (313b to 317b) of the conveyance roller pairs (313 to 317) from the other rollers (313a to 317a) in conjunction with an operation of opening the housing 301 against the main body.

An image forming apparatus includes an opening closing unit openably arranged between first and second positions and an associating mechanism connecting a body unit with the opening closing unit and operating in association with the opening closing unit. The associating mechanism includes plural compression springs and a buffer member, urges the opening closing unit with a first compression spring among the plural compression springs when the opening closing unit is placed at the first position, urges the opening closing unit with the first compression spring and a second compression spring when the opening closing unit is placed at a third portion between the first portion and the second position, and buffers the motion of the opening closing unit with the buffer member when the opening closing unit is placed at a fourth position between the second position and the third position.

An image reader device includes: an original placement part; a holder supporting the original placement part and forming, with the original placement part, a first boundary extending in a first direction; an image reading part movable in a vertical scan direction parallel to the first direction; and an open-close unit closable relative to the original placement part and including a press member which presses an original on the original placement part. The press member includes a first zone and a second zone arranged in the first direction. The first zone includes an extended portion extending beyond the first boundary from the original placement part to the holder when the open-close unit is located at a closed position.

An image reading apparatus includes: a housing including a processing unit configured to process image information; an opening and closing member openably and closably provided on the housing, the opening and closing member including a reading unit configured to read an image from an image holding medium and configured to obtain image information from the image; a connection member that electrically connects the reading unit and the processing unit; and a protective member including a first protective member rotatably supported by the opening and closing member and a second protective member rotatably supported by the housing and rotatably connected to the first protective member, wherein rotation axial directions of the first protective member and the second protective member are the same direction as a rotation axial direction of the opening and closing member, and the connection member is accommodated in the protective member and protected by the protective member.

A medium feeding device includes a lower portion unit in which a feeding roller is provided, and an upper portion unit in which a separating roller is provided and which is connected to the lower portion unit so as to be openable and closable. The lower portion unit has a cover member which covers a holding portion of the feeding roller while exposing a portion of the feeding roller to the transport path, and the cover member is configured to be removable in a direction including a component directed toward an upstream side in the transport direction by being attachable to and detachable from the lower portion unit.

A controller of an image reading apparatus is configured to cause the reading device to read an image on an original with moving a reading location from a first position to a second position, after reading the image on the original with moving the reading location from a third position to the first position, the third position being a position between the first position and the second position and spaced from the first position by a particular distance and determining a width of the original in the main scanning direction. The controller is configured to further move the reading location from the second position to the first position, and detect an instruction to continue reading a subsequent original during a period before the reading location reaches the third position. When the instruction is detected, the controller stops moving the reading location when it reaches the third position.

An image reading apparatus includes a conveyor defining a conveyance path including an upper path, a lower path including a reference portion and a first and second inclined portions, and a curved path, and a first reading unit for reading an image of the sheet when passing the first inclined portion. The conveyor includes a chute member forming a guide surface. The chute member includes a first chute member forming a first guide surface defining the upper path and a second chute member forming a second guide surface defining the first inclined portion. The first chute member forms a third guide surface defining the second inclined portion.

An upper unit configured to open and close an upper portion of a lower unit includes: a first reading unit disposed in a medium transport path, the first reading unit being configured to read a surface of a transported medium; a substrate coupled to the first reading unit; a cable having one end and another end, the one end being coupled to a first coupling portion of the first reading unit, the other end being coupled to a second coupling portion of the substrate; and a facing portion facing the lower unit in a state in which the upper unit is closed, the facing portion being configured to be attached to and detached from the upper unit. The cable is disposed at a position exposed when the facing portion is detached from the upper unit.

An image reading apparatus includes a scanner, a sensor, and a controller. The sensor is configured to detect an original at a predetermined position. The controller is configured to determine whether or not an immediate execution mode in which no user operation is needed to cause the scanner to start scanning is set, and in case the immediate execution mode is determined to be set, determine whether or not a scan start condition is satisfied. The scan start condition includes the sensor detecting the original at the predetermined position. The controller is configured to control the scanner to start scanning, upon a standby time of a predetermined amount being passed since the scan start condition is satisfied.
