Abstract: An apparatus for forming a pattern has a beam position detector, a fine-section scale corrector, a pulse data selector, and a control pulse signal generator. The beam position detector measures a position of the beam on a scanning-line. The fine-section scale corrector changes a scale of a series of fine-sections to a series of corrected fine-sections, in accordance with a scale-change rate, to change a scale of the pattern. The pulse data selector selects a set of pulse data, corresponding to a length of the corrected fine section that the beam passes, from a series of sets of pulse data. The control pulse signal generator successively generates a sequence of control pulse signals in accordance with the selected set of pulse data.

Abstract: In a scanning optical system, a partial light blocking member having an annular light blocking part (for blocking off part of the incident laser beam entering the annular area around the central axis of the laser beam) is placed on an optical path between the laser light source and the polygon mirror. The scanning optical system including such a partial light blocking member is installed in a printer. By the effect of the partial light blocking member, the intensity of side lobes (several rings of light accompanying the main beam) is prevented from exceeding a threshold value even when optical surfaces of an imaging optical system of the scanning optical system have certain microscopic undulations, by which black stripes occurring in halftone printing can be eliminated.

Abstract: A zoom lens camera includes an optical-element drive mechanism for a photographing optical system, and a zooming-associating mechanism for associating a zooming-associated driven member with a zooming operation to be driven by the optical-element drive mechanism in a ready-to-photograph state, and for releasing the association of the zooming-associated driven member with the zooming operation between the ready-to-photograph state and the retracted state. The zooming-associating mechanism includes three rotational members, and includes a master rotational member and a slave rotational member at opposite ends thereof. Opposed surfaces of two adjacent rotational members include rotation transfer portions engaged with each other at predetermined relative angular positions so as to integrally rotate. The slave rotational member rotates together with the master rotational member after relative rotations among the two adjacent rotational members occur in sequence when the photographing optical system changes from the retracted state to the ready-to-photograph state.

Each of the plurality of optical path deflection units is capable of varying the deflection direction of the beam in the auxiliary scanning direction. A plurality of second imaging optical systems converge the beams deflected by the deflection units on target surfaces, respectively. A position adjusting system is provided to adjust a position of each of the second imaging optical systems so that the positional relationship of the second imaging optical system with respect to the beam incident thereon is maintained.
