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 reciprocally movable carriage, an image forming unit, a first drive source, a vibration suppressor, and a vibration-suppression controller. The reciprocally movable carriage moves in a main scan direction. The image forming unit is mounted on the carriage. The first drive source moves the carriage. The vibration suppressor suppresses vibration caused by movement of the carriage, and includes a vibration suppression member having a mass smaller than a mass of the carriage and a second drive source independent of the first drive source to move the vibration suppression member. The vibration-suppression controller drives the second drive source to cause the vibration suppressor to perform vibration suppression operation during at least one of an acceleration period and a deceleration period of the carriage, and stops movement of the vibration suppression member during a constant-speed period of the carriage.

摘要： A heating device includes a holder, a receiver, a heating unit, a vertical mover, and circuitry. The holder holds a heating target object. The receiver removably holds the holder. The heating unit heats the heating target object. The vertical mover moves at least one of the receiver and the heating unit vertically relative to each other, between a non-contact heating position and a contact heating position. The circuitry causes the vertical mover to move the at least one of the receiver and the heating unit to the non-contact position, causes the heating unit to heat the heating target object in a non-contact state, causes the vertical mover to move the at least one of the receiver and the heating unit to the contact heating position, and causes the heating unit to heat the heating target object in a contact state.

摘要： In an image forming apparatus, a carriage mounts a recording head for discharging droplets, and moves in a main scan direction. A guide member slidably guides the carriage. An encoder scale is arranged along the main scan direction. An encoder sensor reads the encoder scale. The carriage includes a head mounting part for mounting the recording head, and a sensor attaching part for attaching the encoder sensor. The sensor attaching part is provided so as to be extended from the head mounting part. The encoder scale is arranged at a location which the encoder sensor can read. A partition member is provided to separate the head mounting part from the sensor attaching part in the carriage. The head mounting part is arranged in a first space, and the sensor attaching part and the encoder scale are arranged in a second space separated from the first space by the partition member.

摘要： An image forming apparatus includes a main body and a printing assembly. The printing assembly includes a carriage, an encoder scale, an encoder sensor, and a flexible cable. The carriage has a head mounting part and a board mounting part arranged along a direction perpendicular to the main scanning direction. The head mounting part mounts a recording head. The board mounting part mounts both the sensor and a carriage-side circuit board connected to the cable. A housing of the body has a first cover portion to cover an area opposing the head mounting part and a second cover portion to cover an area opposing the board mounting part. The first cover portion is openably disposed at the body to allow a user to open the first cover portion. The second cover portion is stationarily fixed at the body to prevent a user from opening the second cover portion.

摘要： A heating apparatus includes an apparatus body, a receiver, a heating device, and a partition. The receiver holds a heating target so that the heating target is insertable into and removable from the apparatus body. The heating device is disposed above the receiver, to heat the heating target. The partition partitions an upper space above the heating device into a first space facing the heating device and a second space facing an upper surface portion of the apparatus body.
