The engaging member and the moving member are configured to be separated at a distance from one another when the medium is not conveyed. The moving member moves the imaging device by engaging with the engaging member only when the medium has a thickness greater than the distance.

A medium-discharging device includes: a device main body including a medium-discharging section that discharges a medium; a medium-receiving tray that receives the medium discharged by the medium-discharging section; and a pressing member that is configured to be attached to and detached from to the device main body and presses the medium discharged by the medium-discharging section against the medium-receiving tray in a state in which the pressing member is attached to the device main body, in which the pressing member is configured to switch, in the state in which the pressing member is attached to the device main body, between a first state in which the pressing member comes into contact with the medium-receiving tray and a second state in which the pressing member retreats upward so as to be apart from the medium-receiving tray.

An image reading apparatus includes a first image reading unit, a second image reading unit provided on a side opposite from the first image reading unit with respect to a sheet feeding passage, a first guiding member, a second guiding member, a first unit holding the first image reading unit and the second guiding member, and a second unit holding the second image reading unit and the first guiding member. One of the first unit and the second unit is movable relative to the other unit so as to open the sheet feeding passage.

An image reading device according to the present disclosure includes a support plate, a CCD sensor, an insulating member, a CCD mounting board and an elastic member. The CCD sensor is arranged on one surface of the support plate. The insulating member is arranged on the other surface of the support plate. The elastic member fixes the CCD mounting board to the support plate. The elastic member includes: a main body portion; a first arm and a second arm which are bent with respect to the main body portion and which have a first engagement portion and a second engagement portion that are engaged with the edges of the support plate; and a protrusion portion which is provided in the main body portion and which presses the CCD mounting board toward the support plate. The tip end portion of the first arm is bent at an acute angle.

A scanner is provided and includes a load bearing element, a scan assembly, a transparent plate and a casing. The load bearing element includes a support element and a base. The support element is disposed on the base and surrounds the base. The scan assembly is configured to perform a scan operation and is disposed on the base. The transparent plate is disposed on the support element and is configured to bear an object. The casing includes a first casing part and a second casing part. The second casing part includes a bottom plate and at least one cylinder. The at least one cylinder is disposed on the bottom plate. The load bearing element is disposed on the at least one cylinder, and is located between the first casing part and the second casing part. A first buffer space is formed between the base and the bottom plate.

An image reading apparatus includes a scanner casing having a contact glass on an upper face, and located on an upper side of a main body frame of the image forming apparatus, a document retention member openably covering the upper face of the scanner casing, a hinge mechanism pivotably supporting the document retention member, a leg portion to an upper end portion of which the hinge mechanism is fixed, an insertion hole formed in the scanner casing, and having an opening oriented upward, in which the leg portion is inserted; and a reinforcing tube attached to an inner face of the insertion hole. The scanner casing includes a first housing, and a second housing mounted on an upper side of the first housing. The reinforcing tube is held between the first housing and the second housing in an up-down direction, and restricted from moving in the up-down direction.

The present invention provides a smart, electronic desk to facilitate and improve interactive learning. The desk comprises a student desk having a table, a computer such as a tablet having a touch-screen interface, and a document camera all integrated together. The interface displays electronic information to the student and provides a graphic user interface that allows the student to interact with programs or apps through graphical icons and visual indicators. The document camera, also known as a visual presenter, captures images and/or video of documents or other objects placed on the table. The computer comprises a bilateral communications interface to communicate information such as, but not limited to video, between the computer and optional document camera at the electronic desk, and any number of other computers.

A document conveyance apparatus includes a loading portion having a loading surface for a document, a rotating member, a detection unit, a feeding roller, and a support portion. The rotating member includes a front end portion protruding from the loading surface and rotates about a rotary shaft by being in contact with the loaded document. The detection unit detects rotation of the rotating member and detects presence or absence of the loaded document. The feeding roller feeds the document by being in contact with the document loaded on the loading surface. The support portion rotatably supports the rotary shaft. When the rotary shaft is viewed from an axial direction, the rotary shaft includes a recessed portion recessed from an outer periphery section of the rotary shaft toward a shaft center of the rotary shaft. The support portion is in contact with the recessed portion to rotatably support the rotating member.

An image reading device includes a housing, a reading unit, a flat cable, and a support member. The reading unit is movably provided in the housing and configured to reciprocally move from a start position to an end position in a reading range. One end of the flat cable is coupled with the reading unit and a predetermined portion thereof on the other end side is fixed to the housing. The flat cable is stored in a bent state in the housing. The support member is provided in the reading unit and configured to support the flat cable and displace, in response to a movement position of the reading unit, a support point of the flat cable in an up-down direction with respect to a coupling portion coupling the one end of the flat cable with the reading unit.
