決め固定していた。2. Description of the Related Art For example, in an image input apparatus, a document placed on a document table is irradiated with light from a light source, which is a light emitting means, and the image of the document is photoelectrically converted by a reflected light from the document through a projection lens. When reading with a CCD as a means, the light source is positioned and fixed according to the angle of view and the focus position of the projection lens so that the image reflected by the document of the light source is not reflected within the angle of view of the CCD.

取りが行えるとは限らないという問題があった。When the illumination light source is fixed, the illumination light source is fixed at a position where the image is not reflected even when the angle of view of the lens is maximized. When the angle of view of the lens is set narrow, the range where the illumination light source is not reflected becomes large. However, since the illumination light source is fixed assuming that the angle of view of the lens is the largest, the illumination position cannot be changed according to the angle of view of the lens. Therefore, there is a problem in that it is not always possible to perform shooting and reading at an appropriate illumination position.

ト5,7からそれぞれCPU4に終了の信号を送る。FIG. 1 shows the configuration of the first embodiment of the present invention. In FIG. 1, a CCD 1 is a surface sensor, and a document illumination light source is a Xe tube 2. The light emitted from the Xe tube 2 strikes the original 3 placed on the original table 12 and is reflected. Manuscript 3
The reflected light from the light enters the CCD 1 by the function of the projection lens 6, and the original 3 can be read. The focus unit 5 and the zoom unit 7 are connected to the CPU 4. The zoom unit 7 adjusts the angle of view of the projection lens 6 according to a command from the CPU 4. Further, the focus unit 5 focuses the projection lens 6 according to a command from the CPU 4 so that the reflected light from the original 3 is imaged on the CCD 1. Even when the zoom lens is used, the focal position moves slightly with a change in the angle of view. For this reason,
It is desirable to perform focusing after adjusting the angle of view. When the focusing and the angle-of-view adjustment are completed, the two units 5 and 7 send end signals to the CPU 4, respectively.

Position the tube 2. The position of the Xe tube 2 is within a range where there is no reflection in the image. As shown in FIGS. 2 and 3,
The reflection range changes depending on the angle of view and the focus position of the projection lens 6. As shown in FIG. 2, when the angle of view of the projection lens 6 is widened or the focal position is farther away, the reflection range A shown by the diagonal line becomes wider. On the contrary, as shown in FIG. 3, when the angle of view of the projection lens 6 is narrowed or the focus position is close, the reflection range B shown by diagonal lines is narrowed. Therefore, FIG. 2 and FIG.
As shown in, the X-axis corresponds to the angle of view and focus position of the projection lens 6.
The position of the e-tube 2 is set in advance so that the difference in optical path length is the shortest within a range without reflection (the optical path length difference is the optical path length between the nearest side of the document and the light source, and the farthest side). The difference in the optical path length with the light source).

Is driven to move the rack gear 9 and the Xe tube 2. As described above, the position of the Xe tube 2 is determined based on the angle of view and the focus position of the projection lens 6. CPU4 is the motor 1
Based on the rotation amount of 1 and the output from the origin detection means (not shown), the movement amount of the rack gear 9 is obtained and the position of the Xe tube 2 is grasped. When it is determined that the Xe tube 2 has moved to the set position, the driving of the motor 11 is stopped.

The amount of light emitted from the Xe tube 2 is changed depending on the position of the tube 2. The amount of emitted light can be set by preparing a table corresponding to the angle of view and the focus position in advance and using it. Also,
In addition to changing the amount of emitted light, changing the gain value of CCD 1,
By changing the shading correction data, it is possible to deal with the change in the reflected light amount accompanying the change in the illumination position. These values are also set corresponding to the position of the Xe tube 2. The change of each value is performed by the instruction of the CPU 4.

You may set the gain value of CD1, and shading correction data. By adopting this method, it is possible to cope with a change in reflectance due to a difference in paper quality of the document, and it is possible to illuminate the document with a more appropriate light amount.

Therefore, the Xe tube 2 may be positioned at the same time when the projection lens 6 is focused and the angle of view is adjusted.

る。Since it is impossible to set the incident angle of the illumination light to 90 degrees, when there is only one illumination light source, there is a difference in the amount of illumination light between a portion far from the illumination light source of the original 3 and a portion near the same. As a result, uneven illumination may occur in the captured image, with bright and dark portions. 4 and 5
As in the second embodiment shown in, two Xe tubes 2 are provided,
Illuminating the original 3 from two directions can reduce uneven illumination. By combining the gears 13, 14, the pulley 15, the belt 16 and the like, it becomes possible to move the two illumination light sources with only one motor 11. However, FIG.
Also, the gear 14, the pulley 15, the belt 16 and the like in FIG.
The original 3 should be attached at a position where the irradiation light is not blocked.

In this case, the two rack gears 9 are attached so that the gear 10 is vertically sandwiched. In order to make the incident angles of the two Xe tubes 2 on the original 3 equal, the motor position is displaced in the horizontal direction from the center of the original. However, the motor 11 is attached to a position where the irradiation light on the original 3 is not blocked. Although the gear 10 and the rack gear 9 are located within the range of reflection in the image, the reflection can be prevented by processing the gear 10 and the rack gear 9 into black with low reflectance.
