a base portion on which the object is placed;

a post for supporting said image pickup means to be located above said base portion; and

illumination means for illuminating the object, wherein said post can be raised/lowered from/to a surface of said base portion, on which the object is placed,

said illumination means, which is provided with enclosures, each having an opening portion, can be raised/lowered from/to and are foldable to periphery portions of said base portion, and

the opening portions of each enclosure of said illumination means are covered with the periphery portions of said base portion when said image input apparatus is in a storage state having a collapsed configuration with said image pickup means resting on said base portion.

2. The apparatus according to claim 1, wherein said post and said illumination means can be solely or simultaneously raised/lowered.

3. The apparatus according to claim 1, wherein when said illumination means is folded, said illumination means can be stored at a level lower than a level of the surface on which the object is placed.

4. The apparatus according to claim 1, wherein one end of said post is axially supported on a corner of said base portion.

5. The apparatus according to claim 1, further comprising transmission illumination means, which is provided in said base portion, for illuminating the surface of said base portion from its underside, and wherein said illumination means, which is folded to the periphery portion of said base portion, provides illumination of the object via said transmission illumination means.

6. The apparatus according to claim 1, further comprising a supporting member for supporting said illumination means to be located above said base portion, wherein one end of said supporting member is supported to be pivotally movable to a side portion of said base portion.

7. An image input apparatus for picking up an image of an object using image pickup means, and outputting an image signal of the object, comprising:

a base portion on which the object is placed;

a post for supporting said image pickup means to be located above said base portion;

illumination means for illuminating the object, wherein said illumination means has enclosures with opening portions, and the opening portions of each enclosure of said illumination means are covered with periphery portions of said base portion when said image input apparatus is in a storage state having a collapsed configuration with said image pickup means resting on said base portion; and

a supporting member for supporting said illumination means to be located above said base portion,

wherein said post can be raised/lowered from/to a surface of said base portion, on which the object is placed,

one end of said supporting member being supported to be pivotally movable at the periphery portions of said base portion, and

said illumination means can be raised/lowered from/to and are foldable to the periphery portions of said base portion.

8. The apparatus according to claim 7, wherein said post and said illumination means can be solely or simultaneously raised/lowered.

9. The apparatus according to claim 7,

wherein when said illumination means is folded, said illumination means can be stored at a level lower than a level of the surface on which the object is placed.

10. The apparatus according to claim 7, wherein one end of said post is axially supported on a corner of said base portion.

11. An image input apparatus for picking up an image of an object using image pickup means, and outputting an image signal of the object, comprising:

a base portion on which the object is placed;

a post for supporting said image pickup means to be located above said base portion;

illumination means for illuminating the object;

a supporting member for supporting said illumination means to be located above said base portion,

wherein said post can be raised/lowered from/to a surface of said base portion, on which the object is placed,
