摘要： A bypass feeder, which is included in an image forming apparatus, includes an opening/closing unit opening and closing with respect to an apparatus body between a unit closed state and a unit open state, a bypass tray opening and closing with respect to the opening/closing unit between a tray closed state and a tray open state, a linkage including a flexible-member fixing member and connecting the opening/closing unit to the apparatus body, and a flexible member having one end fixed to the fixing member and the other end fixed to the bypass tray. When the opening/closing unit is changed to the unit open state while the bypass tray is rotated away from the opening/closing unit to the tray open state, the fixing member of the linkage shifts by pulling the flexible member to hold the bypass tray at a substantially horizontal line with respect to a sheet loading surface.

摘要： A drive transmitter includes a first unit including a coupling portion having grooves spaced at an angle of 180 degrees in the rotational direction, and a second unit having projections spaced at an angle of 180 degrees in the rotational direction. The projections are configured to be inserted into the grooves of the coupling portion. The coupling portion has a guiding portion and a non-guiding portion. The guiding portion is sloped, with a height from a bottom face of the grooves decreasing in the rotational direction of the first unit, and is configured to guide the projections to the grooves. The non-guiding portion is disposed at a point symmetrical position to the guiding portion to an axial center of the first unit. One of the projections is not in contact with the non-guiding portion while another one of the projections is in contact with the guiding portion.

摘要： A sheet feeder, which is included in an image forming apparatus, includes a sheet bypass member openably closable to one side surface of a body of the image forming apparatus, a pickup roller to feed and convey a sheet loaded on the sheet bypass member, and an arm to hold the pickup roller and to open and close with the pickup roller. The arm includes a contact portion extending in a shape of projection toward an upstream side from the pickup roller in a sheet conveying direction of the sheet bypass member. As the sheet bypass member is rotated upward to be closed and stored to the side surface of the body, the contact portion of the arm contacts the sheet bypass member to rotate the arm upward to cause the sheet bypass member to approach to the side surface of the body.
