Abstract: A belt driving device includes plural rotating members around which a belt member extends, each rotating member rotating about a rotating shaft; and contact members disposed at both sides of the belt member in a width direction. The rotating members include a first rotating member, having a dimension less than a width of the belt member in a direction of the rotating shaft. Each contact member has a first contact point at which the contact member contacts the belt member and a second contact point closer to a corresponding one of the end portions in the width direction than the first contact point and at which the contact member contacts the belt member such that an angle between the contact member and the rotating shaft at the second contact point is greater than an angle between the contact member and the rotating shaft at the first contact point.

Abstract: A moving apparatus includes: an exposure unit that forms a latent image by exposure; a support unit that supports the exposure unit so that the exposure unit is displaceable, a guide groove guiding a movement of the support unit to move the exposure unit between an exposure position and a retracted position; a first link unit that includes a first shaft portion, and a second shaft portion that swings about the first shaft portion to transmit force used to move the exposure unit; a second link unit that connects the support unit and the second shaft portion of the first link unit; and a coupling shaft that connects the support unit and the second link unit and is guided by the guide groove.

Abstract: A moving mechanism includes a moving object to be moved between a first position and a second position where the moving object takes a stationary orientation different from a stationary orientation for the first position; a first projection and a second projection provided at different positions, respectively, on the moving object; a member having a first guiding groove that guides the first projection when the moving object is moved between the first position and the second position; and a member having a second guiding groove that guides the second projection when the moving object is moved between the first position and the second position, the second guiding groove having a different shape from the first guiding groove.

Abstract: A link mechanism includes a rotatable link having a fulcrum pin on which the rotatable link rotates, and a connecting pin provided at a different position from the fulcrum pin; and a supporting member having a guiding groove along which the connecting pin of the rotatable link that is moved between two positions is guided, and a supporting groove in which the fulcrum pin of the rotatable link is rotatably supported. The guiding groove of the supporting member includes a long-side guiding portion shaped with a curvature that is greater than a curvature of a substantially arc shape defined by a radius corresponding to a distance between the fulcrum pin and the connecting pin of the rotatable link. The supporting groove of the supporting member is a substantially oblong groove extending in a direction intersecting a direction in which the long-side guiding portion of the guiding groove extends.
