The part 20 is provided in a state protruding upward. The drop-preventing protrusion 20 is formed in a rectangular cross section having a predetermined width and height or a rectangular cross section having a curved corner at the upper end surface. As shown in FIG. Along the width direction intersecting the depth direction of the apparatus main body 3, a protrusion shape is provided that is continuous between the insertion holes 17 to which the two opening / closing members 15 are attached. In this embodiment, as shown in FIG. 6, the drop-preventing protrusion 20 is set to a height equal to the upper surface 4 of the image reading apparatus main body 3. However, the present invention is not limited to this, and the height of the drop-preventing protrusion 20 may be set lower than the upper surface 4 of the image reading apparatus main body 3. The protrusion 20 for preventing the fall is integrally formed with, for example, an upper surface cover 21 made of synthetic resin or the like that covers the upper end surface on the back side of the image reading apparatus main body 3, and the surface of the upper surface cover 21 is low. A surface portion 18 is formed.

  Note that the drop-preventing protrusions 20 do not necessarily have to be provided in series between the two opening / closing members 15, and may be provided by being divided into a plurality along the width direction. Further, as shown in FIG. 8, the drop-preventing protrusion 20 is provided over a predetermined length only between the two opening / closing members 15 on the side serving as the reference 7 when the document 5 is placed. May be. In this case, as long as the length of the drop-preventing projection 20 is short, it is possible to further prevent the possibility of damaging the large document by contacting the drop-preventing projection 20.

  For example, as shown in FIG. 9, the drop prevention protrusion 20 opens the automatic document feeder 11 to take out the document 5 placed on the platen glass 6 of the image reading apparatus body 3. As the automatic document feeder 11 is opened, the document 5 is lifted together with the automatic document feeder 11, and then peeled off from the document pressing surface 12 of the automatic document feeder 11. The leading edge of the document 5 that moves from the gap G to the reading apparatus main body 2 to the back side of the image reading apparatus main body 3 collides with the protrusion 20 for preventing the dropping, thereby preventing the document 5 from falling. Is for.

  At this time, the lower surface portion 18 provided with the protrusion 20 for preventing the fall is set lower than the upper surface 4 of the image reading apparatus main body 3 as shown in FIGS. The leading end portion of the document 5 that has passed through the gap G between the conveying device 11 and the image reading device main body 2 moves along the surface of the low surface portion 18, and the leading end collides with the protrusion 20 for preventing the fall. Is prevented.

  As shown in FIG. 6, the drop-preventing protrusion 20 does not necessarily have to be provided at the rearmost end on the back surface side of the low surface portion 18. It may be provided at an arbitrary position. Further, when the above-described drop preventing projection 20 is provided at the rearmost end of the low surface portion 18, the front surface of the original 5 is positioned on the front side of the drop preventing projection 20. Accordingly, the fall of the drop preventing projection 20 protruding from the surface of the low surface portion 18 can be effectively used to prevent the document from dropping more reliably.

  However, as shown in FIG. 10, when the automatic document feeder 11 or a document pressing cover (not shown) is opened or closed, the rear side of the lower surface portion 18 rotates on the rear side of the automatic document feeder 11 or the like. Since this is a moving area, the rear side portion of the automatic document feeder 11 and the drop-preventing projection 20 do not interfere with each other. Even when the operator turns his / her finger to the back side of the automatic document feeder 11, the operator's finger is not caught between the automatic document feeder 11 and the protrusion 20 for preventing dropping. It is necessary to pay attention to.

  Specifically, as shown in FIG. 10, when the automatic document feeder 11 is opened (opening angle is 60 degrees, for example) on the back side of the open / close region of the automatic document feeder 11, the operator's finger It is necessary to secure a space (for example, an interval of about 15 mm) in which no gap is inserted. In order to satisfy such a requirement on the same surface as the upper surface 4 of the image reading apparatus body 3, the drop-preventing protrusion 20 is about 30 mm (= 15 mm) from the corner on the back side of the automatic document feeder 11. / Sin 30 [deg.]) Or more, it is necessary to provide a sufficient length on the back side of the upper surface 4 of the image reading apparatus main body 3, and the image reading apparatus main body 3 may be increased in size.

  On the other hand, the drop-preventing protrusion 20 is not provided on the same surface as the upper surface 4 of the image reading apparatus main body 2 but on the lower surface portion 18 lower than the upper surface 4 of the image reading apparatus main body 2, and the fall prevention is performed. By setting the height of the projection 20 for the image reading apparatus main body 2 to be equal to or lower than the upper surface 4 of the image reading apparatus main body 2, there is no restriction on the position where the drop preventing projection 20 is provided, and the image reading apparatus main body 2 is not enlarged. Further, it is possible to prevent the document 5 from falling by the drop preventing projection 20.

  From the standpoint of preventing the document 5 from falling, the drop prevention protrusion 20 may protrude higher than the upper surface 4 of the image reading apparatus main body 2, but the height of the drop prevention protrusion 20 is the same. If the upper surface 4 of the image reading apparatus main body 2 is exceeded, when a large document is placed on the upper surface 4 of the image reading apparatus main body 2, a part of the large document may abut against the protrusion 20 for preventing the fall and may be damaged. Therefore, it is desirable to set the height of the protrusion 20 for preventing the fall to be equal to or lower than the upper surface 4 of the image reading apparatus main body 2.

  With the above configuration, the image reading apparatus according to this embodiment can prevent the document from dropping while suppressing an increase in apparatus cost due to an increase in the number of parts as follows. It is possible to prevent the original document from being damaged.

  That is, in the image reading apparatus 1 according to the present embodiment, when the image reading apparatus 1 reads an image of the document 5, the image reading apparatus is opened with the automatic document feeder 11 open as shown in FIG. After the document 5 is placed at a predetermined position on the platen glass 6 of the main body 2, as shown in FIG. 3, the automatic document feeder 11 is closed to fix the document 5 on the platen glass 6.

  Thereafter, as shown in FIG. 3, the image reading apparatus 1 displays an image of the document 5 placed on the platen glass 6 by operating an image reading operation start button provided on the operation panel 2. However, the image reading element scans and exposes the image reading element through a light source, a mirror, or an imaging lens for illuminating a document disposed inside the image reading apparatus main body 2. It is like that.

  Thereafter, after the image reading operation of the document 5 is completed, as shown in FIG. 4, the automatic document feeder 11 is opened again, and an operation for taking out the document 5 placed on the platen glass 6 is performed.

  At this time, in the conventional image reading apparatus, when the automatic document feeder 11 or the document pressing cover is suddenly opened, the document 5 and the automatic document feeder 11 are moved together with the operation of opening the automatic document feeder 11. After being lifted from the platen glass 6, it falls from the document pressing surface 12 of the automatic document feeder 11, and from the gap G between the automatic document feeder 11 and the image reading device body 2, the back side of the image reading device body 2. The document 5 may fall.

  However, in this embodiment, as shown in FIGS. 1 and 9, the projection 20 for preventing document dropping is provided on the lower surface portion 18 located on the back side of the image reading apparatus main body 3. The leading end portion of the document 5 that has passed through the gap G between the document conveying device 11 and the image reading device main body 2 moves along the surface of the lower surface portion 18, and prevents document dropping provided on the back side of the image reading device main body 3. Therefore, it is prevented from falling to the rear side of the image reading apparatus main body 3 by stopping against the projection 20 for use.

  Further, in this embodiment, as shown in FIGS. 1 and 9, the projection 20 for preventing document dropping is not provided on the same surface as the upper surface 4 of the image reading apparatus body 2, but the image reading The lower surface portion 18 set lower than the upper surface 4 of the apparatus main body 2 is provided at a height equal to or lower than the upper surface 4 of the image reading apparatus main body 2.

  Therefore, in the image reading apparatus 1, as shown in FIGS. 1 and 2, when reading an image of a large document such as a design drawing, a map, or a poster, the automatic document feeder 11 is moved from the image reading apparatus main body 3. The upper surface 4 of the image reading apparatus main body 2 is removed and the upper surface 4 of the image reading apparatus main body 3 is opened. The unit 16 does not protrude upward from the upper surface 4 of the image reading device main body 3, so that even when a large document is spread on the upper surface 4 of the image reading device main body 3 and pressed by the operator. The large-size original does not hit the protrusion 20 for preventing the original from falling and is not damaged.

  As described above, in the image reading apparatus 1 according to the above-described embodiment, it is not necessary to provide a complicated mechanism or the like for projecting and retracting the projection 20 for dropping the document, and an increase in apparatus cost accompanying an increase in the number of parts is suppressed. Thus, it is possible to prevent the original from falling and to prevent the large-format original from being damaged.
