A combination of a semi-cylindrical reflecting mirror 2 consisting of a light bulb and a reflecting mirror 4, and a combination of a point light source 3 such as a small light bulb and a reflecting mirror 4, as shown in FIG. 2, have been put into practical use.

れるように構成されている。 These illumination devices are designed with optical characteristics such as the imaging lens traditionally used in exposure systems and the gradient index lens array (product name: self-occurring lens array) that has recently become widely used. Accordingly, the illuminance distribution on the document surface as shown in Figure 3 (a: ideal illuminance distribution in an exposure system using an imaging lens, b; ideal illuminance distribution in an exposure system using a gradient index lens array). illuminance distribution).

(2) 光源または反射鏡の開口部の形状を変化させ
る。 In the lighting device, a specific adjustment method for obtaining an ideal illuminance distribution includes, for example: (1) changing the number and position of segments in the light source; (When using a segment type halogen bulb as the light source) (2) Change the shape of the opening of the light source or reflector.

が現状である。 However, illumination devices using either adjustment method can only roughly set the ideal illuminance distribution, and for example, the illuminance distribution on the document surface may be tilted or uneven due to manufacturing variations in the light source or reflector. At present, it is not possible to make strict adjustments.

幅も複写幅に合わせて広くする必要がある。 In addition, when changing the specifications of an electronic copying machine (for example, when changing the maximum copy size from B4 to A3), the width of the light source unit that illuminates the document surface becomes wider because the width of the copy in the longitudinal direction of the slit becomes wider. It also needs to be widened to match the copy width.

照明装置。[Scope of Claims] 1. In the illumination system of a slit exposure type electronic copying machine, a plurality of light source units each consisting of a point light source that illuminates the surface of a document and a reflecting mirror with an elliptical cross-sectional shape, and a plurality of light source units integrated with this light source unit are provided. Consisting of a plurality of sliding parts that linearly slide in the longitudinal direction of the slit and rotationally slide in the document scanning direction (slit width direction), and a control part that individually adjusts the light of each light source unit, By linearly sliding the sliding portion in the longitudinal direction of the slit, the position of the light source unit in the longitudinal direction of the slit is changed, and by rotating and sliding the sliding portion in the document scanning direction, the posture of the light source unit in the document scanning direction is changed. 1. An illumination device for an electronic copying machine, characterized in that an arbitrary illuminance distribution can be obtained on the surface of a document by changing the amount of light from a light source unit through dimming of the control section. 2. The lighting device for an electronic copying machine as set forth in claim 1, wherein the plurality of light source units and the sliding portion have a structure that allows them to be attached to and removed from each other. 3. In the statement of claim 1, the sliding part is provided in the longitudinal direction of the slit, and the sliding part is in contact with the guide rail or shaft provided in the longitudinal direction of the slit and linearly slides in the longitudinal direction of the slit, and in the document scanning direction. a sliding carrier that rotates and slides;
An illumination device for an electronic copying machine, comprising a clamp for supporting and fixing the sliding carrier at an arbitrary position and posture on the guide rail or shaft. 4. The lighting device for an electronic copying machine as set forth in claim 3, characterized in that the guide rail or the shaft and the sliding carrier have a structure for supplying power to a light source unit. 5. The illumination device for an electronic copying machine as set forth in claim 3, characterized in that the sliding carrier has a structure that can be attached to and detached from a guide rail or a shaft.
