Abstract: A CPU of a console includes a status recognition unit and a projector controller. The status recognition unit acquires subject position information, an adjustment end signal, and an irradiation end signal, which are progress status information indicating a progress status of radiography. The projector controller performs control of causing a projector to project guide information which is related to imaging aimed at a subject, the guide information corresponding to the progress status information, onto a preset projection surface of a radiography room.

Abstract: A CPU of an imaging management device has a status recognition unit, an entrance control unit, a speaker control unit, and a monitor control unit. The status recognition unit acquires progress status information indicating a progress status of radiography at each of the plurality of radiography rooms, such as subject position information indicating a position of a subject in the radiography room. The entrance control unit performs entrance control of the subject into the radiography room based on the progress status information. The speaker control unit and the monitor control unit perform output control of guide voice and guide information regarding imaging toward the subject. The entrance control by the entrance control unit and the output control by the speaker control unit and the monitor control unit are performed, thereby shifting the timing of the radiography at the plurality of radiography rooms.

Abstract: An image forming apparatus includes a reader reading an image, an image forming section forming an image on a recording medium, an exterior member having an outer surface housing the reader and the image forming section, and an operating display having an outer surface. The operating display is disposed in front of the reader, accepts an operation performed by an operator, displays an image, and is rotatable about a rotational axis disposed on its front side between a position in which the operating display faces an upper side and a position in which the operating display faces the front side. The outer surface of the exterior member has a first region which is a background behind the operating display in front view and which is colored in a color similar to a color of the outer surface of the operating display.
