At this time, when the document detection sensor (not shown) detects the feeding of the document P, the conveyance roller 13A shown in FIG. 5 is driven to rotate, and the document P is forcibly fed into the internal passage 11. .

(3) The reading unit 14 located in the internal passage 11 reads the image data of the document P moving in the direction of the arrow M1 along the internal passage 11.

(4) The document P from which the image data has been read is discharged from the document discharge port 15 to the outside in an upright state, and then guided to the curved surface 17 of the guide member 16 as shown by the arrow M2.
At this time, the document P discharged in an upright state from the document discharge port 15 moves forward along the curved surface 17 of the guide member 16 as shown by an arrow M2 in FIG. The curving surface 17 of the guide member 16 can form a curl in which the document P (this document is referred to as P1) is curved. Note that the curl is not limited to a state in which the document P is permanently deformed into a curved shape, but is a state in which the document P is elastically deformed along the guide member 16 or a state in which the lower edge contacts the upper surface of the desk. This includes a state in which the sheet is supported in a curved state by receiving frictional resistance.
Thereafter, as shown in FIG. 7, when the document P (P1) is separated from the transport roller 13A of the transport unit 13, the transport force of the transport unit 13 is lost, and the document P (P1) is placed on the installation surface by gravity as indicated by an arrow M3. It falls on the desk which becomes 200.
At this time, the original P (P1) can stand on a desk while maintaining the curved shape due to the curl of the curved shape provided by the curved surface 17 of the guide member 16. In addition, even if the curl does not occur, the document P can stand on its side as long as the document P bends along the curved surface 17.

(5) Thereafter, when the next original P (this original is referred to as P2) is continuously fed, as shown in FIG. 8, the guide member is overlapped with the preceding original P (P1). It moves in the direction of arrow M2 along the curved surface 17 of 16.
Thereafter, as shown in FIG. 9, when the document P (P2) is separated from the transport roller 13A of the transport unit 13, the transport force of the transport unit 13 is lost, and the document P (P2) falls on a desk serving as the mounting surface 200 due to gravity. I do.
At this time, the original P (P2) is placed on the placing surface 200 on the desk while maintaining the curved shape so as to overlap the original P (P1) due to the curl of the curved shape provided by the curved surface 17 of the guide member 16. Can be independent.

In the scanner device 101 of the first embodiment described in detail above, the guide member 16 having the curved surface 17 that is curved with a predetermined radius of curvature is provided at the document discharge port 15 at the rear of the housing 20.

Can have a curved shape.
As a result, the document P sent to the front of the housing 20 via the guide member 16 can stand upright on a desk via the curved surface 17 of the guide member 16. Accordingly, even when a plurality of originals P (P1, P2,...) Are continuously sent one by one, each original P becomes independent and can be stacked on a desk in an upright state. it can.
That is, in the scanner device 101, the guide member 16 having the curved surface 17 is provided at the rear of the housing 20 and at the outside of the document discharge port 15 with a simple configuration. A large number of originals P (P1, P2,...) After scanning can be stacked on a desk in an independent and upright state.

To summarize the above points, in the scanner device 101 according to the first embodiment, by arranging the housing 20 serving as the scanner main body vertically, the occupied area on the desk can be reduced and it does not become an obstacle.
Further, in the scanner device 101, the originals P (P1, P2,...) After the scan processing are independently accumulated on the placing surface 200 on the desk. No plate) or stopper is required, and space-saving installation can be realized.
Further, in the scanner device 101, the document P (P1, P2,...) After the scanning process is reversed by passing through the guide member 16 and returns to the front side (the direction of the arrow b1). The user can stand up and work without hand-picking the document P, always in a seated state.
Further, in the scanner device 101, since the size of the personal computer PC can be made smaller than that of the vertically placed personal computer, an effect of minimizing discomfort as an obstacle is exerted.
