    摘要： An image forming apparatus is capable of forming a clear image by using laser beams projected from a plurality of laser light sources. The image forming apparatus forms an electrostatic latent image on a medium to be scanned by laser beams, which are projected from a plurality of laser light sources and periodically deflected by a rotational deflecting unit, so that the laser beams scan the medium, which is uniformly charged and moving in a sub-scanning direction, in a main-scanning direction perpendicular to the sub-scanning direction. A pixel clock generating unit generates pixel clocks, which are used for controlling timings of projection of the laser beams, separately for each of the laser light sources, and for performing a phase change of each of the pixel clocks; and a phase control unit that controls independently each of the pixel clocks.

    摘要： A projection screen 111 comprises a total reflection prism lens 114 and a lenticular lens 115 provided on the viewer's side of the total reflection prism lens 114. The total reflection prism lens 114 has a plurality of unit prisms 113 on its back surface (the outermost plane of incidence) on which imaging light L is incident. Each unit prism 113 has an apical angle λ that corresponds to the angle between the plane of incidence 113a and the plane of total reflection 113b, and the apical angles λ of the unit prisms 113 vary with the position of each unit prism 113 on the screen plane. In particular, the unit prisms 113 have apical angles λ varying continuously from 30° to 45° so that the apical angles λ on the side distant from the center O of the concentric circles are greater than the apical angles λ on the side close to this center O.

    摘要： A lenticular lens sheet having an entrance surface and an exit surface comprises a base part, an entrance lens part forming the entrance surface and having an array of a plurality of convex lens elements capable of gathering light rays. A tinted layer is formed at least in a portion of the entrance lens part near the entrance surface. A light absorbing layer is formed in light-nongathering regions in the exit surface in which light rays refracted by the convex lens elements do not gather.

    摘要： An image data storing device for an image forming apparatus having a plurality of line buffers to which image data are written from external equipment and from which the written image data are read to form an image. Selectors selectively cause the individual buffers into a read state, write state, and inoperative state. An image forming signal generator generates an image forming signal during one frame of image forming period. During an image forming period, the selectors condition each of the line buffers for any one of the above-mentioned three different states while, during a non-image forming period, they hold the line buffers in the individual states. This allows the line buffers to start operating under the same conditions whenever an image forming period is reached.
