Printing apparatus and tray unit

An object of the present invention is to provide a printing apparatus including a scanner unit openable and closable with respect to a printer body unit for simultaneously achieving smooth opening/closing movement and the downsizing of the apparatus. The printing apparatus includes a first gear member provided in the printer body unit and a second gear member which is attached to the scanner unit so as to be swingable with respect to the scanner unit and which is in mesh with the first gear member. When the scanner unit opens or closes with respect to the printer body unit, the second gear member swings with respect to the scanner unit while retaining a meshing state with the first gear member.

Printing apparatus

There is provided an image forming apparatus including a scanner unit configured to be openable on an apparatus front side with respect to a printer unit due to a first hinge portion on an apparatus rear side, a cover to cover a feed port configured to be openable due to a second hinge portion on the apparatus front side of the feed port, wherein a rotation axis of the first hinge portion is positioned on the apparatus rear side of a rotation axis of the second hinge portion in an apparatus depth direction. Interlocking with an operation to open the scanner unit, the cover moves while a portion thereof is in contact with a surface of the paper feed tray or the sheet placed thereon to open the cover in an interlocking manner.

Image forming apparatus

An operation device includes a cover and a substrate on which a plurality of electrodes which detects a capacitance and which is provided corresponding to each of a plurality of touch switches is mounted. The operation device includes a laminated structure in which at least an elastic sheet that is self-tacking and closely contacts a plurality of electrodes is inserted between the cover and the substrate. At least one through hole is formed at a location on the substrate facing the elastic sheet.

Image reading apparatus and operation device

A printing apparatus includes a printing unit located inside a housing, a scanner unit including a cover located on top of the printing unit, and an operation unit configured to be opened and closed with respect to the housing. When the operation unit is opened, the operation unit moves to a position where the operation unit hinders the opening and closing of the cover, and a part of the printing unit is exposed.

A touch panel includes a ring-like shaped light-transmissive portion. A ring-shaped diffusion surface is formed on the bottom surface of a light guide element. The ring-like shape includes a second region provided at a location corresponding to two light sources adjacent to a first region corresponding to one light source. A distance from a location of the ring-shaped light-transmissive portion to a periphery of the ring close to the light source is greater in the second region than in the first region. Light emitted from the light source and incident to the light guide element is diffusion-reflected on the diffusion surface and a part of the diffusion-reflected light illuminates the light-transmissive portion.

Operation device and image reading apparatus with a touch panel

A plurality of touch switches includes a first switch and a second switch provided adjacent to each other. A distance between an electrode and a surface of a cover at the location of the first switch is smaller than a distance between an electrode and the surface of the cover at the location of the second switch.

A graphic that indicates a switch is formed on a panel at a location corresponding to a first light guide element. A character to be displayed via the panel is formed on a second light guide element. The first light guide element is supported on a substrate, in close contact with an electrode, via a sheet-like shaped attaching member, and the second light guide element is supported by a base material without being supported on the substrate.

Operation device and image reading apparatus

On a bottom surface of a light guide element of an operation device including a panel with a light-transmissive portion, a reflection portion is formed in a first region thereof, which is close to a light source, and a first diffusion surface is formed in a second region of the bottom surface of the light guide element, which is a region distant from the light source. A light-incident side of the light guide element is a non-diffusion surface. Sides other than the light-incident side are second diffusion surfaces. Light that has been emitted from the light source and incident to the light guide element via the light-incident side is totally reflected and is then guided to the first and the second diffusion surfaces and a part of diffusion-reflected light illuminates the light-transmissive portion of the panel.

An image reading device includes a memory unit for storing positional information of a sensor for moving by a drive unit to read an image of a document and a control unit for controlling the drive unit to move the sensor based on the positional information stored in the memory unit. The control unit drives the drive unit by an amount of driving sufficient for an image reading unit to move in a predetermined direction to abut the stop members, controls the drive unit to move the sensor so as to detect the position mark, and updates the positional information of the memory unit to a predetermined initial value based on the detection of the position mark by the sensor. The image reading device can store data of a reference position promptly even if a photo-interrupter is not provided when the data of the reference position is not stored in a memory unit.

Image reading device, method of controlling the same, control program, storage medium and image forming apparatus provided with the image reading device

In an image reading apparatus which can read a transparent original and reflection original, a white background is formed like a sheet. The image reading apparatus is arranged to be movable by a pair of rollers which rotate using, e.g., the driving source of an original feeder. To read a transparent original, the white sheet is moved by the pair of rollers to a position where a transparent original reading illumination unit is exposed. This makes it possible to eliminate trouble in detaching the white background mounted on the back of an original platen in accordance with the type of an original to be read.

Image reading apparatus and image printing apparatus using the same

Images obtained by prescanning a transparent original by an image reading apparatus are output from a printing apparatus as a navigation sheet on which the images are laid out together with additional information fields. The navigation sheet containing additional information is read, and the additional information is recognized. The transparent original which is left after prescanning is scanned, and printing is performed on the basis of the recognized additional information. This makes it possible to print out a desired image under desired conditions from the transparent original, in which a plurality of images are recorded, by operating a single apparatus without any external device such as a host computer.
