An image reading apparatus includes a medium support section that supports a medium to be fed, a reading unit that performs reading on the medium fed from the medium support section, and a mounting section on which the medium to be set on the medium support section is mountable, the mounting section being located outside of a main body including the reading unit.

A light scanning apparatus including: a first holder attached to a housing and configured to hold a first laser light source; a second holder attached to the housing and configured to hold a second laser light source; and a lens to which the laser lights are first incident, wherein the first holder and the second holder are attached to the housing in mutually different positions in a rotation axis direction of a rotary polygon mirror and in an optical axis direction of the lens, so that a first incident light path from the first laser light source to the rotary polygon mirror is placed between a second incident light path from the second laser light source to the rotary polygon mirror and the lens, and the first holder and the second holder overlap one another in the rotation axis direction.

Provided is a method and a device for detecting open and closed states of a platen cover plate of an image reading apparatus. The method includes: controlling a scanning element to scan light at an edge of a platen to obtain a signal value representing a light intensity; determining whether an absolute difference value between the signal value and a preset standard value is greater than a preset tolerance value; sending a prompt signal to prompt a user to close the platen cover plate in response to the absolute difference value being greater than the preset tolerance value; and continuing to perform scanning work on a manuscript on the platen in response to the absolute difference value being not greater than the preset tolerance value. The influence on quality of the scanned image due to incomplete closing of the platen cover plate is prevented.

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.

In one example, an apparatus includes a plate configured to pivot about a pivot point, a pulley coupled to a first planar side of the plate and configured to rotate a belt, a motor coupled to the first planar side of the plate and configured to drive the pulley, and a torsion spring coupled to a second planar side of the plate that is opposite the first planar side and configured to apply tension to the belt.

A compact and portable printer, scanner and copier having dimensions and a housing allowing the device to be portable for travel with a laptop computer or other tablet or portable computing device. The three in one printer has a pivotal carriage for linear and rotational movement of the carriage and an ink cartridge. The printer also has an easily accessible removable ink cartridge maintenance system.

The invention relates to a printing system for printing images and/or documents with at least a first printing module.

To allow flexible setting up, the printing module has a cuboidal housing with a top part, a bottom part, a front part, a rear part and two side parts, the top part with the bottom part and also the two side parts forming a body, which is closed on the front side by the front part and on the rear side by the rear part, a receiving space for a printer being formed within the body and an operator interface and also a removal opening, connected to a removal compartment, for the print media coming out of the printer being formed in the front part.

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.

A multi-function apparatus includes a body, an image reading unit, a document cover and a locking member. The image reading unit is movable between a closed position and an opened position. The document cover is movable between a closed position and an opened position. The locking member is movable to a first position and a second position and includes a first engagement portion and a second engagement portion. In response to a movement of the document cover to the opened position, the locking member moves to the first position and locks the image reading unit to the closed position. In response to a movement of the image reading unit to the opened position, the locking member moves to the second position and locks the document cover to the closed position.

An image forming apparatus includes a printer unit; at least one of a copier unit and a facsimile unit; a lockable tray with a lock, to store a recording medium; an image formation controller to control at least one of the printer unit, the copier unit, and the facsimile unit in response to a request from a user. In response to a print request for printing using the lockable tray, the image formation controller determines whether the print request is from a user authorized to use the lockable tray based on association information between the lockable tray and the user authorized, and causes the printer unit to perform printing when the print request is from the user authorized. When the request is directed to the copier or facsimile unit, the image formation controller prohibits the copier or facsimile unit from performing printing using the lockable tray.
