Next, referring to FIG.
The operation of the CIS 216 at the time of reading image information of an original in a state where the CIS 216 is mounted on the facsimile apparatus 100 will be described. FIG. 5 is a schematic diagram showing a CIS operation at the time of reading image information of a document in a state where the hand scanner according to the embodiment is mounted on a facsimile machine.

The document discharge roller 21 is located immediately above the CIS 216.
8 are arranged. The document discharge roller 218 and the hand scanner 124 are almost fixed to the facsimile machine 100. However, the document discharge roller 218 and the hand scanner 124 may not be properly arranged, that is, may not be horizontally arranged, depending on a manufacturing stage or an assembling operation.

For example, it is conceivable that the left end of the document discharge roller 218 is attached to the CIS 216 by being lowered downward as indicated by an arrow 501. In this case, the right end of the document discharge roller 218 naturally rises upward with respect to the CIS 216 as indicated by an arrow 502. Accordingly, the left end of the original 500 moves as indicated by an arrow 501, and the right end of the original 500 moves as indicated by an arrow 502. As a result, the document has irregularities and bends. further,
Along with the movement of the document 500, the CIS 216 also moves in the direction of the arrow 501 at the left end with the protrusion 404 serving as a fulcrum.
The right end of 216 moves in the direction of arrow 502. As a result, the original 500 and the CI
The distance from S216 is almost the same. As a result, CIS
Reference numeral 216 can accurately read the image information of the document 500.

The left end of the document discharge roller 218 is C
It is also conceivable that the document discharge roller 218 rises upward with respect to the IS 216 as indicated by an arrow 503 and the right end of the document discharge roller 218 falls downward with respect to the CIS 216 as indicated by an arrow 504. Also in this case, the original 500 is also inclined with the inclination of the original discharge roller 218, that is, unevenness or bending is caused. However, with the inclination of the document 500, the CIS 216
Lean too. Therefore, the CIS 216 can accurately read the image information of the document 500.

Next, referring to FIG.
The operation of the CIS 216 at the time of reading image information of a document in a state where the CIS 216 is removed from the facsimile apparatus 100 will be described. FIG. 6 is a schematic diagram showing the operation of the CIS at the time of reading image information of a document in a state where the hand scanner according to the above embodiment is detached from the facsimile apparatus.

When the hand scanner 124 is detached from the facsimile apparatus 100 and used, the image information of an original such as a magazine that has a bend or has irregularities may be read.

For example, the left end of the original 600 is the CIS 21
6 is a case where it curves downward as indicated by an arrow 601. In this case, the right end of the document 600 naturally rises upward and curves with respect to the CIS 216 as indicated by an arrow 602. That is, the document has irregularities or bends. However, with the curvature of the original 600, C
IS216 also has an arrow 601 at the left end with the projection 404 as a fulcrum.
, The right end of CIS 216 moves in the direction of arrow 602. Thereby, even at both ends of the document 600,
The distance between the document 600 and the CIS 216 becomes almost the same.
As a result, the CIS 216 can accurately read the image information of the document 600.

The left end of the document discharge roller 218 is C
There is also a case where the document discharge roller 218 rises upward with respect to the IS 216 as indicated by an arrow 603 and the right end of the document discharge roller 218 falls downward as indicated by an arrow 604 with respect to the CIS 216. Also in this case, the CIS2
16 leans too. Therefore, the CIS 216 can accurately read the image information of the document 600.

As described above, according to the above embodiment, if the original has irregularities or bends, the CIS 216
Swings following irregularities and bending of the document. This allows
The distance between the original and the CIS reading glass 217 can be kept constant. As a result, even if the original is uneven, the CIS 21
6 can read image information accurately.

In the above embodiment, the protrusion 401 provided with the CIS 216 is used as the holding mechanism of the CIS 216.
And the opening 403 formed on the hand scanner 124 side.
And a protrusion 404 provided on the hand scanner 124.
And adopted. Thus, the CIS 216 can be swingably held so as to follow the irregularities of the document. Further, since this configuration can be formed at the same time as the molding of the hand scanner 126, no special process is required. Furthermore, since this configuration does not require any special parts, the hand scanner 1
26 can be constructed at low cost.

According to the above-described embodiment, even when the hand scanner 124 is mounted on the facsimile apparatus 100, the CIS 216 can accurately read image information of an original having irregularities. Further, when the CIS 216 is arranged at a position facing a roller such as the document discharge roller 218 as in the above embodiment, the holding mechanism of the CIS 216 of the hand scanner 124 exhibits a particularly effective effect.

It should be noted that any holding mechanism other than the holding mechanism of the CIS 216 in the above embodiment may be used as long as the holding mechanism swings following the irregularities of the document.

In the above embodiment, the CIS 216 that swings following the irregularities of the original is replaced with the hand scanner 124.
However, the CIS 216 that swings following the irregularities of the document may be fixed to the main body of the facsimile apparatus.

[0072]

As described above, according to the present invention,
Even in the case of a document having irregularities or bending, the CIS swings according to the bending of the document, so that image information can be read accurately.
