A touch key of an operation console includes a circuit board () having a light source (), a light transmitting portion () transmitting light, a non-transparent light shielding portion () and a semi-transparent operation panel () covering upper surfaces of the light transmitting portion and the light shielding portion. The light transmitting portion accommodates the light source. The surfaces of light transmitting portion and light shielding portion in contact with each other are tightly sealed, and the circuit board () and the light shielding portion () cover the light transmitting portion () such that the light is emitted only from the surface in contact with the operation panel (). Thus, leakage of light from around a figure indicating a touch key can be prevented, and the operation console comes to have a high-class look.

Image forming apparatus

A mobile vehicle comprising: an electric undercarriage including a wheel that can travel; and a distance detection unit and a protruding structure which are mounted on the electric undercarriage, wherein the distance detection unit is configured to emit light horizontally in a range of a predetermined center angle around the electric undercarriage and to be capable of detecting a distance to an object present within the range of the predetermined center angle, the protruding structure includes one or more of an antenna, a warning light, an imaging device, and a lift mechanism unit, and the protruding structure is placed on the electric undercarriage at a position outside the range of the predetermined center angle, whose mobile vehicle can reliably recognize an obstacle without creating a blind spot in a traveling direction.

An operating device includes a first support frame, a support shaft, an operating panel, a second support frame, and a spring. The first support frame is fixed to a front side of a main apparatus. The support shaft projects from the first support frame in a widthwise direction of the main apparatus. The second support frame is pivotally supported on the support shaft in such a manner as to be displaceable within a predetermined range in the widthwise direction while supporting the operating panel. The spring biases the second support frame in a first direction which the second support frame is pressed against the first support frame. The first support frame has a plurality of recesses on a circumference of a circle that is concentric with the support shaft. The second support frame has a first projection capable of being engaged into any one of the recesses.

Operating device, information processing apparatus, and image forming apparatus

An image forming apparatus in one embodiment of the present invention is an image forming apparatus that includes a main body that performs processing to form an image on a recording paper, the image forming apparatus including, an ion generating section that is external to the main body, generates ions and emits those ions to the outside.

An image processing device includes a processing section, a load section, an operating section, and a display unit. The processing section performs processing upon sheets of a recording medium. The operating section includes input keys which receive input operation for controlling the processing section, and is disposed over the load section. The display unit displays information corresponding to input operation from the operating section. And the operating section can be freely shifted between a pulled out position in which its input keys are exposed to the exterior, and a storage position in which it is stored internally, and, in the storage position, is disposed below the display unit.

Image processing device

Cleaning performance of a cleaning pad for cleaning a charging wire is maintained so that the charging voltage of an image carrier by a charging wire is stabilized. A charging wire cleaning apparatus is provided with a cleaning pad for cleaning a charging wire which charges an image carrier, a slider which is a supporting body for supporting the cleaning pad, and a screw shaft which is a moving mechanism for reciprocating the slider in parallel to the charging wire. When the slider is at a predetermined position of the reciprocation range, the cleaning pad and the charging wire are separated, and the cleaning pad is adapted to be shifted with respect to the charging wire in this state.

Charging wire cleaning apparatus

An image reading device includes an image reading section, a frame, and an operating unit. The image reading section is configured to obtain image data by reading an image carried on a document. The frame supports the image reading section. The operating unit has an operating section including a plurality of input keys adapted to receive an input operation for controlling the image reading section, and an operating unit body supporting the operating section for displacement between a drawn-out position in which the input keys are exposed to outside and a housed position in which the input keys are housed inside. The operating unit is supported by the frame.

In an image forming apparatus, an electrostatic latent image formed on a surface of a photoreceptor is developed into a toner image. A printing paper transported on a transport belt is brought into contact with the surface of the photoreceptor and an electric field is applied to the printing paper from a rear surface of the transport belt by a transfer roller to transfer the toner image onto the printing paper. The transfer roller applies different levels of electric field to the printing paper, so that a predetermined transfer electric field is applied to a region other than a leading edge of the printing paper being transported. An electric field weaker than the predetermined transfer electric field is applied to the leading edge. Even in the presence of a projection generated when the printing paper is cut, the printing paper naturally strips off from the surface of the photoreceptor.

Image forming apparatus, image forming method, and transfer device

A charging device includes a rotatable screw gear, a motor, a support, and a protruding member. The screw gear is positioned along length of a linear electrode. The motor rotates the screw gear in forward and reverse directions. The support holds the cleaning member mounted so as to be in contact with the electrode, and is mounted unrotatably but reciprocably between a first end and a second end of the electrode. The member extends perpendicular to the length of the electrode from the support, and has a projection for being elastically fitted into a thread groove of the screw gear along a radial direction of the screw gear. The member is configured in such a manner that a distance between a starting point of elastic deformation of the member and a contact point between the projection and a thread of the screw gear differs according to whether the support is moved forward or backward.

Charging device and image forming apparatus

An image forming apparatus and a maintenance method thereof are provided to enable rotation and replacement of a peeling claw at a suitable timing before the peeling claw is deformed or damaged. Several peeling members are disposed in a width direction of a drum-shaped photoreceptor. Each peeling member is disposed with a peeling claw and a collision sensor detecting that the peeling claw collides with a sheet. A collision history value of each peeling claw is stored and managed based on a collision detection signal from the collision sensor; if the peeling claw reaching a preset rotation request value exists in the read collision history values of the peeling claws, a rotation request of the relevant peeling claw is reported; the collision history value of the rotated peeling claw is rewritten; and if the peeling claw reaching the rotation request value does not exist, a print process is performed.
