Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to the structure of a document table of a copying machine, which is particularly suitable for copying thick books.

(Prior Art) In a conventional general copying machine, as shown in FIG. 4, a reading surface 3 made of a glass plate is provided at the center of the platen on the upper surface of the box-shaped machine body 1. A corner 2'of the platen was adjacent to one end of the reading surface 3.

(Problems to be solved by the invention) When copying a book having a relatively large thickness with the above-described conventional copying machine, the binding portion A'of the book A is lifted from the reading surface 3 (see FIG. 4). , When copying in this state, the portion of the copy paper B corresponding to the vicinity of the binding position A'is
As shown in FIG. 5, a blackening B'occurs, and the characters and the like written in that portion are distorted, which makes it impossible to copy accurately.

(Object of the Invention) The present invention has been made in view of the above-mentioned points, and when copying a book having a large thickness, it is possible to suppress the lifting of the binding portion of the book from the reading surface as much as possible, and there is almost no darkening. An object of the present invention is to provide a copying machine capable of making accurate copying.

(Means for Solving Problems) The gist of the present invention for achieving the above-mentioned object is to provide a copying machine having a reading surface on the upper surface of a machine body having a box shape, and the copying machine is provided from one end of the reading surface. The corners of the document table reaching the side surface of the main body are inclined downward to be chamfered, and the corner member is attached to the side surface of the main body of the machine so that the corner member can be fitted into the chamfered portion and is rotatable.

(Operation) According to the copying machine of the present invention, when copying a book having a large thickness, first, the corner member that can be fitted into the chamfer is rotated to the side of the machine body to expose the chamfer. By positioning a binding position of the book at one end of the reading surface and covering the reading surface with the page to be copied, and fixing the other page along the chamfered portion inclined downward from one end of the reading surface,
By touching the reading surface deep into the binding area, you can make accurate and beautiful copies with little blackening and no distortion throughout. It should be noted that after the copying of the book is completed, the corner member rotated laterally of the machine body may be fitted in the chamfered portion as it is, which will not be an obstacle.

(Embodiment) An embodiment of the copying machine of the present invention will be described below with reference to the drawings.

1 and 2, the copying machine main body 1 has a box shape, and a document table 2 is formed on the upper end portion of the copying machine main body 1. A reading surface 3 made of a transparent glass plate is provided at the center of the upper surface of the document table 2. Further, a copy paper delivery port 4 is opened at a substantially intermediate position on one side of the machine body 1,
A copy paper receiver 5 is mounted so as to project laterally from the lower end of the delivery port 4. The corners of the document table 2 extending from one end of the reading surface 3 to the side surface of the machine body 1 are chamfered by inclining downward from one end of the reading surface 3. A cover body 7 is provided on the side surface of the machine body 1 below the chamfered portion 6 so as to cover above the delivery port 4. By the way, the cover body 7 has one end pivotally attached to the side surface of the machine body 1 so that the cover body 7 can be deployed laterally in a range of about 90 degrees from the state of being attached to the side surface of the machine body 1, and the cover body 7 is The chamfered portion 6 is provided at the end.
The corner member 8 which can be fitted to the is integrally projected. Therefore, when the cover body 7 is erected to the side of the machine body 1, the corner member 8 at the other end fits into the chamfered portion 6 so that the upper surface of the corner member 8 is flush with the reading surface 3. It constitutes a part of the document table 2. In other words, the structure is the same as that of the document table of the conventional copying machine described above (see FIG. 4). Therefore, for example, when copying a drawing, an original, or the like that is larger than the reading surface 3, or when there is an auxiliary facility (sorter or the like) that requires a corner portion of the original table 2 adjacent to one end of the reading surface 3, It is convenient to raise the cover body 7.

Next, the usage mode of the copying machine of the above-described embodiment will be described. When copying a sheet-shaped original document or a drawing, the cover 7 is erected, and the usage mode in this case is exactly the same as the conventional one. On the other hand, when trying to copy a necessary page from a thick book A such as an encyclopedia, as shown in FIGS. 1 and 2, the cover body 7 is unfolded to the side of the machine body 1 and stretched. The chamfered portion 6 of the document table 2 is exposed at one end of the reading surface 3. The page to be copied of the book A is covered on the reading surface 3, the binding position of the book A is positioned at one end of the reading surface 3, and the other page is added to the chamfered portion 6 inclined downward from one end of the reading surface 3. Hold on to. In this state, the reading surface 3 is brought into contact deeply with the binding portion of the book A, and the page to be copied can be surely copied. Further, since the upper portion of the delivery port 4 through which the copy paper is delivered is covered by the cover body 7, the delivery of the copy paper is not obstructed by the lower end portion of the book A during copying.

Next, FIG. 3 shows another embodiment of the present invention, which is different from the above embodiment in the following points. That is, in the copying machine according to the present embodiment, the lower end portion of the right-angled triangular prism-shaped corner member 9 corresponding to the chamfered portion 6 is rotatably pivoted on the side surface of the machine body 1 at the lower end of the chamfered portion 6 in the embodiment. When the corner member 9 is unfolded, the chamfered portion 6 and the lower inclined surface 9a of the corner member 9 are connected in a flush state, and the chamfered portion has an area twice that of the chamfered portion 6 of the embodiment. It is configured to be. Therefore, when a thick book or the like is copied, the book or the like is more securely fixed to the reading surface 3.

In addition, in FIG. 3, members common to the above-described embodiment are represented by using the same reference numerals as those in FIGS. 1 and 2.

(Effects of the Invention) As described above, since the present invention has the above-described configuration, it has the following effects.

(1) When copying a book having a large thickness, it is possible to suppress the floating from the reading surface in the vicinity of the binding position of the book as much as possible, so that almost no dark portion is generated on the copy paper, Characters can be copied accurately, and the finish of the entire copy paper is improved.

(2) The structure is not particularly complicated and the manufacturing cost is not higher than that of a conventional general copying machine.

(3) Since the corner member that can be fitted into the chamfer is provided on the side surface of the copying machine body so as to rotate, the corner member is fitted into the chamfer when copying a normal paper surface (other than a thick book). If they are combined, the corner member does not get in the way and the upper surface of the corner member can be flush with the reading surface. This is convenient when there is an accessory such as a sorter that requires a corner of the platen adjacent to one end of the surface.
