Abstract: A light deflector includes a rotary polygon mirror and a motor to rotate the rotary polygon mirror. The rotary polygon mirror includes reflecting surfaces to reflect light emitted from a light source and a hole portion provided in a rotational axis direction. The motor includes a shaft portion in the hole portion and a support member supporting the rotary polygon mirror. The support member is fixed to, and coaxial with, the shaft portion, and includes an insertion portion in the hole portion. The rotary polygon mirror includes a protruded portion near the hole portion and protruding from at least one reflecting surface orthogonal to the rotational axis direction. The protruded portion includes a fitting portion fitted to the shaft portion or the support member and in which a portion continued from a hole portion surface is protruded toward the rotation center more than the surface forming the hole portion.

Abstract: An image forming apparatus for forming an image on a recording material includes a photosensitive member; an optical scanning unit including a light source, an optical box, and a cover; and a fan. The fan is provided so that air from the fan directly impinges on the cover of the optical scanning unit. As seen in a direction perpendicular to a rotational axis of the rotatable polygonal mirror, a rib extending from a top plate of the cover toward an optical box side is provided at a portion of the cover in the neighborhood of a light beam emitting port of the optical scanning unit. The cover is provided with an extended portion extended from the rib in a light beam emitting direction.

Abstract: A transducer array including a plurality of transducers each of which receives an acoustic wave and transduces the received acoustic wave into an electric signal, and a support member supporting the transducers, and having an inner surface which is defined by a quadric surface of revolution formed according to an imaginary quadratic curve rotating about an imaginary rotation axis. Each transducer includes a receiving surface having a substantially parallelogram shape defined by four vertexes, the receiving surface being connected to the support member so as to be oriented towards the inner surface of the support, and a transducing element transducing an acoustic wave, received by the transducer via the receiving surface, into an electric signal. The receiving surface is arranged in the transducer array such that any one of the four vertexes is closer to the imaginary rotation axis than the other three vertexes.
