Abstract: A fluid-filled vibration damping device including a movable film housed within a housing space of a partition partitioning a pressure receiving chamber and an equilibrium chamber. An outer peripheral end of the movable film includes a contact part and a sealing part being respectively in contact with a pressure receiving chamber-side wall inner surface and an equilibrium chamber-side wall inner surface of the housing space. A communication passage, which communicates with a gap circumferentially between the movable film and the housing space, is provided away from the contact part in the outer peripheral end of the movable film. The outer peripheral end of the movable film will be separated from the equilibrium chamber-side wall inner surface due to a pressure differential arising between the two chambers so as to form a relief passage interconnecting the two chambers including the gap and the communication passage.

Abstract: A document feeder includes an input tray (part of a document placing portion) on which a document is placed, an output tray on which the document output from a document output port in an output direction is stacked, and a substrate including a light source that emits light to the output tray. The output tray is disposed below the input tray. The substrate is fixed to the document placing portion at an oblique angle relative to a horizontal reference of the document feeder such that the optical axis of the light source extends toward the document output port.

Abstract: An image-forming apparatus includes an image-reading unit. The image-reading unit includes a first member and a second member. The image-reading unit includes an original-document-feeding apparatus that conveys an original document from an original-document-loading tray to a discharge tray via a read position.

Abstract: When a first elapse time ?t3 from time point t1 of stop of a transport motor reaches a first specified time S1, a registration roller electromagnetic clutch is engaged. At time point t2 at which the first elapse time ?t3 reaches 50 ms, normal rotation of the transport motor is started. At time point t3 at which a second elapse time ?t4 from the time point t2 reaches a second specified time S2 (a given length of time), a reverse roller electromagnetic clutch is switched from an engaged state to a disengaged state, rendering reverse rollers and sheet discharge rollers freely rotatable. At subsequent time point t4, a coil of a solenoid is de-energized, to separate the reverse rollers from each other.
