    • In an optical scanning apparatus, a light source includes a plurality of light emitting elements. A light beam output from the source is scanned and deflected by a polygon mirror so as to form an electrostatic latent image on a surface of a light sensitive member. A control unit controls the source so that the source outputs the light beam in a first period before a second period in which the light beam deflected by the mirror forms the image. During the first period for outputting the light beam from the source a period for scanning a non-image region of the member in a state in which the rotation speed of the mirror is being accelerated or decelerated is made longer than a period for scanning the non-image region of the member in a state in which the rotation speed of the mirror is controlled at a constant speed.
    • 在光学扫描装置中,光源包括多个发光元件。 从源极输出的光束被多面镜扫描并偏转,以便在感光元件的表面上形成静电潜像。 控制单元控制源,使得源在由反射镜偏转的光束形成图像的第二周期之前的第一周期内输出光束。 在用于从光源输出光束的第一周期期间,使得在反射镜的转速加速或减速的状态下扫描部件的非图像区域的周期比扫描非反射镜的周期长, 在反射镜的旋转速度以恒定速度被控制的状态下的构件的图像区域。

    • In an image formation apparatus having a function to detect a direction of an original image, in a case where an image formation mode is set by using a touch panel, a keybutton to instruct whether or not direction detection is to be performed is displayed on a setting screen of an image formation mode to which direction detection is effective, while such the key is not displayed on a setting screen of an image formation mode to which direction detection is not effective. The image formation mode to which direction detection is effective includes a mode to record images of one-face originals onto two faces of a sheet, a mode to arrange and record images of plural originals onto one sheet, a mode to perform stapling at designated corner positions of sheets, and the like.
    • 在具有检测原始图像的方向的功能的图像形成装置中,在通过使用触摸面板设定图像形成模式的情况下,指示是否执行方向检测的按键被显示在 设定方向检测有效的图像形成模式的设定画面,而不在方向检测无效的图像形成模式的设定画面上显示该键。 方向检测有效的图像形成模式包括将单面原稿的图像记录到纸张的两个面上的模式,将多张原稿的图像布置和记录到一张纸上的模式,在指定角度执行装订的模式 片材的位置等。
