An electronic device comprises: a shielding object that is arranged at least in a plurality of directions and shields noise; and a Helmholtz silencer that is arranged in a direction where the shielding object does not exist, the shielding object and the silencer being arranged with respect to a noise source causing noise such as a driving source that is arranged inside an apparatus body, wherein a neck portion of the Helmholtz silencer is directed to the noise source, a plurality of such Helmholtz silencers are provided to correspond to at least two kinds of frequencies, and installed number of the Helmholtz silencers corresponding to at least two kinds of the frequencies respectively, is made different depending on a distance from the noise source.

Electronic device and image forming apparatus

An image forming apparatus includes an image forming unit configured to form an image; a drawer unit configured to be pulled out from a body of the image forming apparatus; a first lock unit configured to receive power from a power supply and perform at least one of lock and unlock of the drawer unit with respect to the body; and a second lock unit configured to perform lock and unlock of the drawer unit with respect to the body by a mechanical operation performed by an operator.

Image forming apparatus with locking drawer unit

The image forming apparatus includes an image forming section; a conveyance path to convey a recording medium to the image forming section; a drawer unit including the conveyance path and configured to be pulled out relative to the apparatus; an electrical cable to electrically connect the drawer unit and an interior of the apparatus even when the drawer unit is pulled out from the apparatus; and a cable holder (a first regulating member) to ensure that that the cable is securely prevented from protruding from the drawer unit. According to the present invention, the electric cable is prevented from running off from the drawer unit due to the folding of the cable caused by the regulating member, so that the electric cable is prevented from getting hung up on the parts disposed in the body.

An image forming apparatus includes a drawer unit configured to be drawn out from a body of the image forming apparatus. The drawer unit includes a carriage path for carrying a recording medium, a lock unit configured to lock the drawer unit in the body, a driving unit configured to drive the lock unit, the driving unit including at least a driving source, and a drawer unit cover configured to cover at least the drawer unit. The drawer unit cover is a part of an outer cover of the body arranged on a side in a drawing direction of the drawer unit. The drawer unit cover is attached to the drawer unit so that the drawer unit cover is removed from the drawer unit in a state where the drawer unit is attached to the body.

Provided is an image forming apparatus including an apparatus body, an operation display unit provided on top of the apparatus body and including an operation display surface that allows an input operation by a user and provides a display for the user, and a supporting member with one end thereof connected to the back of the operation display unit and the other end thereof connected to an upper surface of the apparatus body. The supporting member supports the operation display unit such that the operation display surface faces the front of the apparatus body. Operation display unit connecting sections that connect to the one end of the supporting member are provided on the back of the operation display unit and apparatus body connecting sections that connect to the other end of the supporting member are provided on the upper surface of the apparatus body.

A pressure-applying device includes a swingable unit body, a roller, an opposing member, a pressure-applying unit, and a drive-force transmitting unit. A swinging center of the unit body is set at a position distinct from a rotation center of the drive-force transmitting unit. A direction of action of driving force of the driving unit substantially coincides with a line joining the swinging center and a point at which pressure application force is applied by the pressure-applying unit. A direction of action of the pressure application force is substantially orthogonal to the direction of action of the driving force.

Pressure-applying device, transfer device, and image forming apparatus

An apparatus for use with an office machine for allowing operational conditions of the machine to be set up with ease and promoting easy handling of a menu sheet on which information for selecting the operational conditions are to be written. An operator can condition the machine for desired operation modes simply by marking a menu sheet and then inserting it in a menu sheet reader. Even when the menu sheet jams a transport path defined in the menu sheet reader, for example, it can be dealt with by simple processing.
