摘要:
A toner carrier includes a metal core, a barrel formed on an outer circumference of the metal core and including at least an elastic layer, and a coating formed on outer circumferences of both ends of the barrel. The coating has a thickness and a width of an outer circumference of the coating is different from a width of an inner circumference of the coating. The width is from an end surface of the barrel along an axis of the barrel, and the width of the outer circumference is larger than the width of the inner circumference so that the end surface of the coating is reversely inclined.
摘要:
A guidance device which performs measurement by placing an object without contact, comprising: a virtual image display unit displaying a virtual image; a sample display generation unit making the virtual image display unit display a sample virtual image based on a shape of the object at a position where the object is to be finally arranged; a status detection unit detecting a position and attitude of the object; a correction amount calculation unit calculating a difference between the position and attitude of the object and the position and attitude of the virtual image; and a guidance display generation device making the virtual image display unit display a guidance display indicating the calculated difference in the same position as the virtual image.
