- Various types of copying machines have been proposed and put into practical use. Among these conventional copying machines, there are those that are mainly used for copying thick originals such as books, and those that are mainly used for copying thin single-sheet originals. When copying a sheet original with a copying machine that is mainly used for copying thick originals, the sheet original is generally placed on the original table, held down by the original holding cover, and then moved according to the number of copies you want to make. Copying is performed by reciprocating the document table or by reciprocating the projection optical system the same number of times. However, it is cumbersome to open and close the original holding cover and set the sheet original on the white original clay, and the wind pressure when opening and closing the cover may cause the set sheet original to shift or be blown away. Sometimes,
Very inconvenient and inefficient - This is a major drawback of this type of copying machine, as the types of originals to be copied are generally far more sheet originals than thick originals. Yes, on the other hand, some copying machines that are mainly used for copying sheet originals include those that perform scanning exposure by directly inserting the sheet original into the exposure section, and those that perform scanning exposure by directly inserting the sheet original into the exposure unit, and those that automatically feed the sheet original into a predetermined position into the device. There is a type in which the original is set in the original position, the exposure scan is repeated within the apparatus a number of times according to the number of copies desired, and then the original is automatically ejected. Among these, the former type of copying machine, which is mainly used for copying thick originals, has to wait for the completion of the exposure and scanning process for the previous original before replacing the next original. The operation is very slow because the sheets can be inserted one after another into the exposure section, and the reciprocating mechanism of the document table or the projection optical system is fixed, so the overall configuration of the device is simple. in,
It has the advantage of being inexpensive to manufacture. In addition, this type of copying machine may be able to copy thick originals by adding appropriate auxiliary means. As for the auxiliary means that makes it possible to copy thick originals, there is, for example, the one shown in No. 1. A document carrier on which a thick document l such as a book to be copied is placed is hidden in the document transport path of the sheet document copying machine 3, and is slid toward the exposure section j. The tip is the 1st flK
When the document detection sensor≦ is pressed, the first document conveyance roller 7 begins to rotate and conveyance of the document carrier 2 begins. The original is conveyed until its leading edge presses the first original detection sensor t, and is temporarily stopped by a clutch mechanism (not shown). The photosensitive drum 9 is rotated to a predetermined position, and conveyance is restarted at a predetermined timing in the copying process.

During the copying process when the conveyance is resumed, the document carrier is conveyed by the first document conveyance roller 7 and the first document conveyance roller 7σ, and the document carrier passes through the exposure window 12 for exposure by lighting the exposure lamp /). The image of the upper thick original l is projected onto the photosensitive drum 9 through the projection optical system 13. Exposure lamp with reflective mirror l#
It increases the lighting efficiency of l. The original carrier 2 that has been exposed is received until it is ejected. In order to convey such a document carrier, as shown in FIG. Binion 1lt - This is done by forming a binion I near the shaft end of the first document conveying roller and meshing the rank 17 with the binions /I and n.

However, in such a document carrier conveyance mechanism, after the document carrier 2 is once conveyed, the clutch mechanism stops the rotation of the binion/I at a predetermined position, and the copying machine waits for the document to be exposed. Must be. On the other hand, since the binion 19 is constantly rotating, when the binion is once stopped and then rotated again, the rotational phase of the binion /I of the first Haraaki conveyance shaft and the binion 19 of the @J Haraaki conveyance shaft may shift. Therefore, the conveyance is restarted and the binion/
When the tip of the rack of the document carrier conveyed by I engages with the pinion 19, the teeth of the rack break off, causing irregular conveyance of the carrier and causing harmful disturbances on the copied image, causing damage to the copied image. ``There are drawbacks that reduce quality.

The operation of the document carrier conveyance device having such a configuration will be explained. A book carrier 2 on which a thick original such as a book is placed is slid along the original transport path in the original transport direction. When the tip of the document carrier presses the actuator l of the first detection sensor 4, the main motor of the copying machine body B (not shown)
begins to drive, and the first conveyance shaft 2# rotates. At the same time, solenoid 1 is energized to remove the pawl from the gap between the teeth of ratchet 3 and open ratchet 36.
Therefore, the rotation of the first transport shaft n is transmitted to the binion ll' through the binion/9' fixed to the second transport shaft 2# and the timing bell) 3#.The ratchet 3t is in the open state, so the binion/I ' is integrally connected to the tome ring H via a bush integrated with the binion/I' and a clutch spring (not shown), and the first conveying shaft n is rotationally driven by the rotational force transmitted to the binion/I'. For this reason, the pinion/I mounted on the first conveyance shaft rotates the double-sided timing belt 1 and the pinion 19 loosely fitted on the first conveyance shaft. Book carrier is sensor 4 actuator #
At the position where 1 is pressed, the tip of the rack 17 engages with the double-sided timing bell (U), so the teeth n on the outer periphery of the double-sided timing bell ()L engage with the rack 17, and the document carrier is conveyed directly in the document conveyance direction. The document carrier λ is transported, and when its tip presses the actuator J of the second detection sensor L, the energization to the solenoid I is interrupted, and the claw N is moved by the spring 31 and engages with the teeth of the ratchet 3B. Stopping the rotation of the ratchet 9 Therefore, the clutch spring whose one end is locked to the ratchet 3 B stops rotating, but the pinion/l'
The bushing, which is integrated with the clutch spring, overcomes the frictional force with the clutch spring and rotates while sliding with the clutch spring. Therefore, the rotation of the binion /I/ is not transmitted to the first conveyance shaft n, and the double-sided timing belt stops rotating, so the document carrier
It remains temporarily stopped at the position where the actuator J of the detection sensor 4 is pushed. During this temporary stop, the double-sided timing belt 2/and the opinion 19 also stop, and the first conveying shaft 2#
is rotating, so the second conveyance shaft slides on the binion /9 and rotates. Next, when the copying process of the copying machine is ready, the solenoid n is energized at a predetermined timing to start the iris, and the first conveyance shaft, and therefore the double-sided timing belt, are rotated, so that the document carrier is again conveyed to the exposure section. ! transported to. In this case, Binion/I e /9
is always in mesh with the inner teeth n of the timing pel) V, so the rotational phases of both binions always maintain a predetermined relationship even when conveyance is restarted.
