Abstract: 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.

Abstract: 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.

Abstract: A connection preventing member includes an insertion portion and a handle. The insertion portion is configured to mechanically engage with a connector housing having an opening connected to an input and output (I/O) port of an electric apparatus. The insertion portion includes a lock unit configured to engage with an engagement portion of the connector housing. The handle is connected to the insertion portion via a connecting portion. The handle is configured to be foldable at the connecting portion and separable from the insertion portion after the insertion portion is inserted into the connector housing. The lock unit is at a position at which the insertion portion covers a terminal portion of the connector housing when the lock unit engages with the engagement portion and the handle is separated from the insertion portion.

Abstract: 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.
