摘要： A toner container includes a container body, an opening, a cover, a toner discharge port, a shutter, a cylindrical structure, protrusions, and an identifier. The shutter is attached to the cover and includes a main shutter covering the toner discharge port. The main shutter moves between a closed position to close the toner discharge port and an open position to open the toner discharge port. The protrusions are on both sides of the cover and protrude in a direction orthogonal to a toner container mounting direction. The identifier is on the cover to indicate a toner color. The cylindrical structure's leading end is downstream of leading ends of the protrusions in the mounting direction. The main shutter's leading end is downstream of the protrusions' leading ends in the mounting direction when the main shutter is in the closed position. The protrusions are downstream of the identifier in the mounting direction.

摘要： An image display control device according to the present invention includes a display control unit, an obtaining unit, a drawing unit, a deleting unit, and an operating unit. The display control unit displays an image on a display device. The obtaining unit obtains contact position information or proximity position information of a drawing device, which is relative to a display area of the display device. The drawing unit generates a drawn image, compose a display image of an information processing apparatus with the drawn image, and displays the composite image on the display device. The deleting unit deletes the drawn image from the displayed image, and display on the display device. The operating unit operates the information processing apparatus. The drawing device switches and specifies a generation and deletion of the drawn image, and an operation of the information processing apparatus.
