光プリンタヘッドの点灯方法
Document Type and Number:
Japanese Patent JP4543487
Kind Code:
B2
Abstract:
An optical printer head is provided in which light exposure of one pixel may be increased. An optical printer head for exposing a photosensitive drum to form pixels thereon comprises a light-emitting element array including two or more lines of light-emitting points, and a rod-lens array for projecting light emitted from the light-emitting array onto the photosensitive drum to form a line of light spots. Each of the lines of light-emitting points has the same pitch in a main-scanning direction in parallel with an axis of rotation of the photosensitive drum, and the light-emitting points of respective lines of light-emitting points are arranged so as to be lined up in a sub-scanning direction perpendicular to the axis of rotation of the photosensitive drum.
