    Abstract: A sheet conveyance device correcting skew of a sheet being conveyed includes: a rotational shaft extending perpendicularly to a sheet conveyance direction; conveyance rollers disposed at predefined intervals and into which the rotational shaft is inserted; gate members being coaxial with the conveyance rollers and disposed between the conveyance rollers along the rotational shaft, the gate members each having an arc-shaped part partially surrounding the rotational shaft and a stopper protruding radially outwards from the arc-shaped part; and a mounting plate elongated along the rotational shaft and being supported rotatably around the rotational shaft and holding the gate members in a same orientation. After the sheet abuts against at least one of the stoppers, the stoppers are pushed out of the conveyance path by the sheet. When the stoppers are positioned on the conveyance path, openings of the arc-shaped parts face toward a downstream side in the conveyance direction.

    Abstract: In a paper cassette, a guide slides on a tray to place a sheet at a proper position. A lift mechanism uses a restoring force of an elastic member to push up the tray and make the sheet on the tray approach a pickup roller. When the paper cassette is pushed by a user from an opened position, which is out of the housing of a printer, to a closed position, which is in the housing, an adjuster mechanism mechanically converts a force of the user pushing the paper cassette to the restoring force of the elastic member from a time the guide reaches a specific point on a trajectory along which the guide travels together with the paper cassette, thus adjusting the strength of the restoring force continuously to a distance by which the guide overruns the specific point.

    Abstract: A toner container attachable to and detachable from a main body of an image forming device and including: a first chamber containing toner; a second chamber adjacent to the first chamber through a partition wall and downstream of the first chamber in a toner supply direction; and a switching member in the second chamber that is movable or rotatable and has a shell structure. The partition wall has a first aperture. A bottom wall of the second chamber opposing the partition wall has a second aperture and sits on the main body. The shell has third and fourth apertures. The fourth aperture coincides with the second aperture when the third aperture coincides with the first aperture, and the first aperture is closed by the shell when the third aperture faces an inner wall surface of the second chamber.

    Abstract: An electrical machine includes an exhaust fan and an exhaust port on which an optional device is mounted. The optional device includes a duct, an electric fan, and an air flow sensor. Through the duct, an exhaust gas from the exhaust port is guided. The electric fan draws in the exhaust gas flowing through the duct and discharges the exhaust gas into an atmosphere. The air flow sensor detects presence or absence of the exhaust gas flowing from the electrical machine. The air flow sensor includes an air path partitioned from an inside of the duct by a partition wall. The air path includes an exhaust gas and an exit port. The exhaust gas intake port includes an opening facing the exhaust gas. The exit port communicates with the atmosphere at a position outside the duct.
