摘要： An image forming apparatus includes a housing, a carriage, and a damping mechanism. The carriage includes an image forming mechanism and moves back and forth in a main scan direction. The damping mechanism generates an impact to suppress vibration caused by movement of the carriage. The damping mechanism suppresses vibration during at least one of acceleration and deceleration of the carriage, and is inactive during movement of the carriage at a constant speed. The damping mechanism suppresses vibration when acceleration of the carriage equals or exceeds a predetermined threshold acceleration. The damping mechanism includes a suppression member and a mass member that strikes the suppression member. The suppression member is at least one of a shock absorber and an elastic member. Shock absorbing characteristics of the shock absorber and elasticity of the elastic member are variable.

摘要： An image forming apparatus includes a recording head, a conveyance belt, a charger, a reverse passage, and an auxiliary conveyance roller. The belt is looped around at least two rollers to adhere a recording medium thereto by electrostatic force and convey the medium. The belt defines a normal conveyance area in which the medium is conveyed in a first direction. The reverse passage delivers the medium turned around in an area downstream from the belt in the first direction and sends the medium back again to a portion of the belt upstream from the head in the first direction. The reverse passage includes an opposite conveyance area of the belt in which the medium is conveyed in a second direction opposite the first direction. The auxiliary conveyance roller is disposed at least one of an entry part and an exit part of the opposite conveyance area.

摘要： An image capture system including two imaging systems of the same structure each having a wide-angle lens, which includes a front group, a reflection surface, and a rear group arranged in order from an object side, has a field angle larger than 180 degrees, and bends an optical axis of the front group toward the rear group by the reflection surface, and an imaging sensor, obtains an image in a solid angle of 4π radian by combining images imaged by the imaging systems. Each of the two wide-angle lenses includes the reflection surface between the front group and the rear group, the reflection surfaces are made to be common to the two imaging systems. This reduces an interval between lenses nearest to the object side in the front groups of the two wide-angle lenses, thereby reducing a distance between maximum field angles of the two wide-angle lenses.
