    摘要: A stage apparatus includes a base, a stage that can move along the surface of the base that serves as a movement plane, and an imparting mechanism that gives an inertia force to the base using a mass body that moves in a direction vertical to the movement plane. The movement of the mass body in the imparting mechanism in the vertical direction is controlled so that a force in the rotation direction around an axis parallel to the movement plane that is generated in the base when the stage moves along the movement plane is reduced. Thus, a drive reaction force that is generated when the stage is driven can be effectively cancelled out and the effect of the drive reaction force can be reduced.

    摘要: Mounting trays for storing therein sheet-shaped recording materials are used to record thereon images. A laser exposing unit forms a latent image of an image on the recording material in an exposure process by irradiating laser. A heat development unit performs a heat development process for the recording material on which the latent image has been formed. The mounting trays the laser exposing unit and the heat development unit are disposed along upper/lower directions of an image recording apparatus in this order of image processing operations for the recording material. A length of a transport path for a recording material is short within this image recording apparatus to shorten processing time.
