An operation display device includes: a touch panel including a transparent base and an electrostatic capacitance sensor sheet, the transparent base having an operation surface in a front surface thereof to which or with which an operation body approaches or comes into contact, the sensor sheet being provided on a back surface of the transparent base to detect the approach or the contact of the operation body; a liquid crystal panel facing a back surface of the touch panel; an outer cover covering a portion of the touch panel other than a front surface of the touch panel; and a sealing member sealing a gap between the touch panel and the liquid crystal panel, the outer cover including a spacer between the touch panel and the liquid crystal panel, and the sensor sheet being not to be interposed between the transparent base and the spacer.

Operation display device and image forming apparatus

A display device includes an operation screen attached to an apparatus to accept instructions for the apparatus, display lamps each including a light emitter to provide notification of a state of the apparatus, a light source to emit light, a substrate on which the light source is mounted, a lens that makes up the light emitter of each one of the display lamps, a light guide to guide the light emitted from the light source to the lens, and a housing that covers the substrate. In the display device, the housing has an opening at which the lens is exposed, at an area including a corner formed by an edge of a top face on which the operation screen is disposed and a side face. In the display device, the lens and the light guide is coupled to each other at a coupling surface, and the coupling surface is orthogonal.

Display device and image forming apparatus

An extended operation device mountable to and demountable from an apparatus body includes an extended operation device body, an operation device, and a pair of insertion portions. The pair of insertion portions extend in a first direction parallel to an operation surface of the operation device with respect to the extended operation device body. One insertion portion and the other insertion portion of the pair of insertion portions are provided on one side and the other side, respectively, of the extended operation device body with respect to a central position of the extended operation device body in a second direction that is parallel to the operation surface of the operation device and intersects the first direction. The pair of insertion portions are inserted into a pair of insertion holes provided in the apparatus body to mount the extended operation device to the apparatus body.

Extended operation device and image forming apparatus

A cooling device, which is included in an image forming apparatus, includes a cooling device including an air blower, an airflow divider, an air flowing passage, and an air exhaust opening. The air blower blows air toward a cooling target device. The airflow divider divides the air exhausted from the air blower into at least two airflows such that an air flowing direction of the air is changed to a direction perpendicular to an air exhausting direction of the air. The at least two airflows pass through the air flowing passage. A wall of the air flowing passage is disposed facing the cooling target device. The air exhaust opening is disposed on the wall of the air flowing passage to cause the air to pass through toward the cooling target device disposed in a direction intersecting the air flowing direction in the air flowing passage.
