Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a copying apparatus in which an automatic document feeder for automatically feeding documents is attached to a document table so as to be openable and closable.

Normally, a copying machine equipped with an automatic document feeder has one end of the automatic document feeder 2 rotatably mounted on the upper surface of the copier main body 1, as shown in FIGS. 1 and 2. It is attached so that it can be opened and closed to the document table 4 provided on the top surface of the unit 1 on which the document 3 is set, and when the automatic document feeder 2 is closed, the document table 4 is
I try to cover the entire surface of the area. The automatic document feeding device 2 has a plurality of rollers 7 and 8 fitted and fixed to a pair of shafts 6, 6 which are rotatably pivoted at both ends of a frame 5 having an open bottom. A conveyor belt 9 is placed between each roller 7 and 8. On the other hand, a portion of four drive rollers 10, which are rotated by being driven by a drive device disposed inside the main body 1, protrude near both sides of the document table 4 on the upper surface of the main body, and the automatic document feeding device 2 In the closed state, the rollers 7 and 8... are connected to the drive roller 10.
... is pressed to rotate the conveyor belt 9.

By the way, when copying, for example, a single-page original using such a copying machine, when the automatic original feeding device 2 is tilted toward the original platen 4 and the original 3 is inserted from the feeding side 2a, the original 3 is transferred to the conveyor belt 9... The document is conveyed to the document table 4 while being sandwiched between the drive rollers 10, is copied, and is discharged from the discharge side 2b. In addition, when the above-mentioned automatic document feeder 2 cannot be used, such as with books, etc., the object 11 to be copied is directly set on the document table 4 with the automatic document feeder 2 open as shown in FIG. do. In this case, the object 11 to be copied is entirely covered with a rubber sheet 12 removably attached to the upper surface of the main body 1 so that exposure light during copying does not leak to the outside.

Incidentally, the rubber sheet 12 is usually attached only when the automatic document feeder 2 cannot be used, such as when handling books, and is normally removed and stored. Therefore, each time a book or the like is to be copied, the rubber sheet 12 must be attached, which makes the operation very troublesome, and also requires a place to store the rubber sheet 12 when it is not needed, and there is a risk that the rubber sheet 12 may be lost. There is also. Furthermore, if the seat is repeatedly attached and detached, there are other problems such as the sheet surface becoming heavily soiled.

The present invention was developed in view of the above circumstances, and even when copying objects such as books for which automatic document feeding devices cannot be used, there is no need to attach or detach the rubber sheet each time, and the present invention has excellent operability. The purpose of this invention is to provide a copying device.

Embodiments of the present invention will be specifically described below with reference to FIGS. 3 and 4. Incidentally, the same parts as in the conventional copying apparatus already explained in FIGS. 1 and 2 are given the same numbers, and the explanation will be omitted.

A storage section 21 for storing the rubber sheet 20 covering the document table 4 is integrally formed on the circumferential wall surface of the main body 1 on the document supply side by press molding, etc., and the rubber sheet 20 is placed on the upper end of this storage section 21. The rubber sheet 20 is attached to the inward side wall surface 21a of the housing section 21 via a magnet 22 whose upper edge is rotatably mounted and the rubber sheet 20 is attached to its lower end. The inner side surface portion 21a of the main body portion 21a is inclined inward of the main body portion 1 from the upper portion to the lower portion thereof.

Further, a document receiving table 23 is provided on the upper surface of the main body 1 on the document discharge side to receive the copied document.

According to this configuration, when copying an object 11 such as a book for which the automatic document feeder 2 cannot be used, the object 11 is placed on the document table 4 with the automatic document feeder 2 open. The rubber sheet 20, which is directly set and stored in the storage section 21, is laid down on the document table 4 side, and the object 11 to be copied is covered with it to make a copy. In addition, when copying a single-page original, use the rubber sheet 20.
Fold it down to the storage section 21 side and store it within this storage section 21. Therefore, even when copying books or the like, there is no need to attach or detach the rubber sheet 20 each time, and when it is not needed, it can be stored in the storage section 21 provided on the side of the main body 1, making the operation extremely easy. It is simple, does not require a special storage place to store the removed rubber sheet, and there is no risk of powder loss or staining. Further, since the rubber sheet 20 is fixed along the inner side surface portion 21a of the main body which is inclined toward the inner side of the main body, it is difficult for dust and the like to adhere to the rubber sheet 20.
