    • An exposure device for forming an image on a photosensitive member is disclosed, which is provided with a shutter unit disposed between the photosensitive member and a light source. The shutter unit includes a plurality of shutter elements adapted to open and close for selective transmission of the light from the light source therethrough. Further provided are driving means for reciprocally moving the shutter unit along the row of the shutter elements, and control means for controlling opening and closure of the shutter elements.With the above constructed exposure device, the shutter elements are repeatedly opened or closed when moved to a different position along the row of shutter elements by means of driving means. An image of higher resolution is thus formed on the photosensitive member by means of the light passed through the light transmitting area corresponding to the shutter element kept open.
    • 公开了一种用于在感光构件上形成图像的曝光装置,其设置有设置在感光构件和光源之间的快门单元。 快门单元包括适于打开和关闭的多个快门元件,用于选择性地透射来自光源的光。 还提供有用于沿快门元件的行相互移动快门单元的驱动装置和用于控制快门元件的打开和关闭的控制装置。 利用上述构造的曝光装置,当通过驱动装置沿快门元件行移动到不同位置时,快门元件被重复地打开或关闭。 因此,通过穿过与保持打开的快门元件相对应的透光区域的光,在感光构件上形成较高分辨率的图像。
