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 apace by the partition member.

摘要： An optical-element angle adjustment device includes: a first protruding portion and a second protruding portion formed to protrude on the same axis from opposite positions across an optical mirror held by a mirror holding portion; a first adjustment member having an elongated hole formed along a direction corresponding to a first rotation direction representing a direction in which the axis is rotated, in which the second protruding portion is inserted; and a second adjustment member fitting with the second protruding portion protruding from the first adjustment member. A position of the second protruding portion in the elongated hole is adjusted using the first adjustment member. An angle of rotation of the second adjustment member in a second rotation direction with the axis as a rotation axis is adjusted. Thereafter positions of the first adjustment member and the second adjustment member are fixed.

摘要： A liquid discharge device includes a first liquid container, a liquid discharger, a second liquid container, a first liquid flow passage, and a second liquid flow passage. The first liquid container is configured to contain liquid. The liquid discharger is configured to discharge the liquid supplied from the first liquid container in a liquid supply direction. The second liquid container is configured to contain the liquid supplied from the first liquid container. The first liquid flow passage is a passage through which the liquid is supplied from the first liquid container to the liquid discharger via the second liquid container. The second liquid flow passage is a passage through which the liquid is supplied from the first liquid container to the liquid discharger without passing through the second liquid container.

摘要： A toner container includes a container body, an opening, a cover, a toner discharge port, a shutter, a cylindrical structure, protrusions, and an identifier. The shutter is attached to the cover and includes a main shutter covering the toner discharge port. The main shutter moves between a closed position to close the toner discharge port and an open position to open the toner discharge port. The protrusions are on both sides of the cover and protrude in a direction orthogonal to a toner container mounting direction. The identifier is on the cover to indicate a toner color. The cylindrical structure's leading end is downstream of leading ends of the protrusions in the mounting direction. The main shutter's leading end is downstream of the protrusions' leading ends in the mounting direction when the main shutter is in the closed position. The protrusions are downstream of the identifier in the mounting direction.
