That is, both the front side and the rear side of the stopper 2θ are rotatably supported by hinges 275.75. Under normal conditions, the plate is pushed upward by the plate springs 76.degree. 76, and the blocking portion 77 protrudes beyond the document table 5 to position the document a. Also, when paper is ejected,
The document table 5 is pushed downward by the solenoid 69.
It is designed to be evacuated from.

As shown in FIG. 11, the original/document transporting device N9 in which each unit is configured in this manner has frames 78 and 79 attached to the rear side of the frame 61 of the transport unit 50, and these frames 78 and 79. It is supported by the upper part of the copying machine 1 via hinges 80, 80, and is thereby able to be opened and closed. The frame 78 also includes a drive motor 2.
A control printed wiring board (forward/reverse drive circuit) 48 and the like of No. 7 are attached, and are supplied with power and logic signals from the copying machine 1 via a connector 81 and the like.

Next, the operation of the document conveying device 9 will be explained. 2 and 12, first, when a document a is guided by the document insertion guide 7 and pressed against the document feed roller 12.13, an entrance switch consisting of an entrance reed switch 11 and a document detection actuator 10 is activated. 82 detects document a. This signal is sent to the main controller 83 of the copying machine I. When the main controller 83 receives this signal, it starts a preparation operation for starting the copying operation of the copying machine I. After a predetermined period of time, the main controller 83 switches the forward/reverse drive circuit 4 of the original transport device 9.
Send a reverse signal to 8. The forward/reverse drive circuit 48 rotates the drive motor 27 in the reverse direction based on this signal. This drive motor 27
Due to the reverse rotation, only the document feed roller Z2°13 rotates, and the document a is fed until it hits the aligning rollers 14 and 15, and is aligned. At this time, the force pushing the lower feed roller 13 (1u11 feed roller I2) is set weak, and the upper feed roller 12 slides on the document a, causing friction, but the upper feed roller 12 is made of white rubber. Since the feed roller I3 is made of white rubber, it will not stain the document a even if it is rubbed.It is more effective if the lower feed roller I3 is made of white rubber.

Next, the main controller 63 of the copying machine 1 controls the pulse disk 3.
6 and a rotation amount detection device 84 consisting of a laser beam detector 37
When it is detected that the drive motor 27 has rotated by a predetermined amount, a signal is sent to the forward/reverse control circuit 48 to stop the drive motor 27 from rotating in reverse and to rotate forward after a predetermined period of time. As a result, the drive motor 27 changes from the reverse rotation state to the normal rotation state, and the aligning roller 14. IB, transport bell) Z 6, l
i Paper rollers 21 and 22 rotate. Then, the document a is placed on the aligning roller 14. The document is sent onto the document table 5 by Z5 and the conveyor belt 16, and stopped with the leading end pressed against the stopper 20. When the drive motor 27 rotates forward by a predetermined rotation amount, the main controller 83 issues a stop signal to the forward/reverse drive circuit 48, thereby causing the drive motor 27 to rotate forward by a predetermined rotation amount.
stops, and the setting of document a is completed. It is also possible to use, for example, a white, soft, spongy roller instead of the conveyor belt I6.

Here, the conveyor belt 16 has a polyester core coated with preurethane to make the surface white, and
The outer surface is finished with a ribbed finish to obtain frictional force, and the conveying force is generated by the weight of the conveyor belt 16 and the leaf spring 67 that pushes the presser rollers 19 provided inside the conveyor belt 16.
It is obtained from the elastic force of... In addition, presser roller Z9
The total force pressing down on the conveyor belt 16 is approximately 100g.
It becomes. Further, the document a is conveyed with reference to the center, and the relationship between the document position when the document a hits the stocker 20 and the positions of the presser rollers 19 is as shown in FIG. Presser roller 19... is conveyor belt I
6 to hold the document a and transport it stably.In order to make this even more reliable, it is effective to forcibly corrugate a part of the transport belt I6. 1
As shown in FIGS. 3 and 14, the belt roller Z7 on the sheet feeding side is provided with large diameter portions 65, 65 approximately symmetrically with respect to the center. That is, for example, the outer diameter of the large diameter portion 65 is 25 mm compared to the standard outer diameter of the paper feed side belt roller 170 of 25 mm.
．． 6111 m, and this large diameter portion 65 creates bulges 85 at both ends of the conveyor belt 16, which actively presses both ends of the document a and increases the conveyance force.

In this case, the document a can be conveyed more smoothly if the force component for conveying the document a is distributed not only near the center but also at both ends. That is, for example, as shown in FIG. 15, when the resultant force F of the conveyance force acts on the center, the document a
If the distribution of the resistance force acting on the original A becomes uneven, it will generate a moment that rotates the original A, and the movement direction A of the original A becomes uneven.
will shift to A' or AI. This is substantially the same even if the conveying force is uniformly distributed over the entire width. However, in this embodiment, as shown in FIG. 16, the conveying force is intentionally distributed at both ends away from the center, so that the influence of the moment caused by the resistive force is unlikely to appear. Therefore, when the conveying force is distributed in the center, the document a is allowed to travel straighter than in the case where the conveyance force is uniformly distributed over the entire width, and the performance of conveying the document a to a predetermined position and causing it to stagger is improved. Figure 17 shows the waves of the bulges 85, 85 appearing on the surface of the conveyor belt 16 when viewed from below, and since the belt roller 18 on the paper ejection side is smooth, the conveyor belt 16 is on the paper ejection side. Is it flat? 20, and there is no adverse effect. Note that although the document a is conveyed based on the center reference, if the conveyance reference is different, it is better to change the distribution of the large diameter portions 65 and 65 as appropriate.

Further, as shown in FIGS. 13 and 14, a part of the frame 61 that supports the conveyance unit 50 is provided with a pressing portion 68 that pushes the conveyor belt I6 downward. Since it is pressed and guided reliably, no gap is created between the stone 4' 20 and the conveyor belt I6 through which the document a can pass. That is, for example frame 6
1 and the document table 5 is 53 m across the entire area, but the pressing part 68 is 1.5 va @, and only this is a gap of 1.5 mm, subtracting the belt thickness of 0.5111. 111I
This will be the gap between II. As a result, even if the conveyor belt 16 waves and vibrates, the gap will not become too large and the function of the stopper 420 will not be impaired.Although the pressing part 68 is provided in the center, for example, multiple parts can be placed at any location. It may be provided.

Moreover, even if it is appropriately placed at a location other than the vicinity of the stone arm 20, it is effective to suppress vibrations and waving of the conveyor belt Z6. In addition, if the pressing part 68 is rotatably attached to a fixed shaft 86 with a roller 87 to restrain the conveyor belt 16 as shown in FIG. 18, the friction with the conveyor belt 16 can be reduced. , which is very effective. In this case, the presser roller 19 floats due to the leaf spring 67, so that the conveyor belt 16 cannot be reliably suppressed.

Next, when the setting of the document a is completed as described above, a copying operation is performed, and when the copying operation is completed, the document ejecting operation is performed as follows. That is, the solenoid 69 is driven, thereby the stone/mother 20 is retracted from the surface of the document table 6, and the document a can be transported. After a predetermined period of time, the drive motor 27 starts normal rotation, the conveyor belt 16 rotates, and the document a is thereby conveyed past the stopper 20, and then is discharged onto the document discharge tray 8 by the discharge rollers 21 and 22. When the drive motor 27 rotates forward by a predetermined amount of rotation, the solenoid 69 becomes non-driven.
θ returns to its original position. Further, when the drive motor 27 has rotated by a predetermined amount, the drive motor 27 is stopped, and the ejection of the document a is completed. Note that the output loss isolator 88 is for detecting a paper jam, and determines the presence or absence of the document a at a predetermined timing to detect the presence or absence of a paper jam.

In the document conveying device 9 as described above, furthermore,
Since the drive motor 27, solenoid 69, etc. are all housed in the device, when installing it to the copier I, only 8111 connectors are needed for electrical connection to the copier 1, and all parts of the copier JK'4 are connected. There is no need to install it separately.゛Additionally, the parts that can be removed from the copying machine I include the Stone 9 unit 52, a protective cover, a magnet, etc.
The installation of all driving parts is completed by installing the document conveying device 9. Therefore, the document conveying device 9 can be easily added to the copying machine 1 later as an option.

In addition, the shift feed roller 12 is driven by one drive motor 27.
．． 13, Aligning roller 14゜15, Conveyor belt Z
6 and discharge rollers 21 and 22, the weight can be reduced and handling is easy.

Furthermore, if the conveyor belt 16 becomes dirty or damaged, it will be necessary to replace the conveyor belt 16.
, transport unit) 517. and the paper ejection unit 51 are connected by screws and a connecting frame 62, and when they are removed, each unit becomes separate and at the same time the belt roller I7
, 1B become free, the conveyor belt 16 can be easily attached and detached.

Next, a case where the document transport device 9 is not used will be explained.
Control is such that when a print switch (shown in FIG. 1) 89 of the copying machine I is pressed, the document conveying device 9 is not driven and only a copying operation is performed. That is, the main controller 83 is provided with a microcomputer, and its RAM is provided with a flag for storing the operating mode of the previous copying operation, as well as various control flags. As shown in FIG. 19, this A flag is set to "0" when a copying operation using the document transport device 9 is performed, and to "1" when a copying operation is performed without using the document transport device 9. be done. Here, as shown in FIG. 20, the document conveying device 9 is installed so as to be openable and closable with respect to the copying machine I, and is usually placed at the solid line position, so that the user can directly press the document af! - It can be opened to the position shown by the broken line so that it can be set on the document table 5. Whether document conveyance device I6 is closed or open is detected by position switch 90 and sent to main controller 83. Then, when the document conveyance device 9 is open, the A flag is reset to "0". The state of the A flag rlJ indicates that the original transport device 9 remains closed after a copying operation that does not use the original transport device 9 is performed. At this time, the document a from the previous copy still remains on the document table 5. Copying operations that do not use the document transport device 9 and are started by pressing the print switch 89 are accepted regardless of the flag, but copy operations that do not use the document transport device 9 and are started by inserting the document a into the document transport device 9 are accepted. This copying operation cannot be accepted when the document feeder 9 is open and when the A7 lag is "1". As a result, when the thick document a such as a book remains on the document table 5, the operation of the document conveyance device 9 is prohibited because the document conveyance device 9 is open. Further, when the thin document a remains on the document table 5, the A flag is set to "1", so the operation of the document conveying device 9 is prohibited. For example, after performing a copying operation that does not use the document feeder 9,
When the original a is inserted into the original transport device 9 before the original a is removed, K displays a paper jam indication and does not accept copies.

Next, a procedure for attaching the document conveying device 9 to the copying machine I will be explained.
