Abstract
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.
