The separated paper 34 is conveyed after the image is read by the close contact image, the sensor 32, and the read roller 45, and is transferred to the document leading detection sensor 48 located on the path of the original reading part. To detect the distinction between the plaintiff and the plaintiff.

Here, the operation state in which the document is conveyed will be described with reference to FIGS. 8 and 11.

8 is a state diagram showing the up and down rotation of the perturbation piece according to the displacement of the cam gear according to the present invention, and (a) to (e) of FIG. 9 are the initial action state diagram for feeding the originals of the document transmitting unit according to the present invention. (A) shows a position diagram of the cam gear, and (B) shows a position diagram of the perturbation piece perturbed in the cam portion.

As shown in the figure, when a predetermined number of documents 34 are loaded, the document 34 is detected by the document presence sensor 49, and the paper feeding operation is performed by the user's operation keys. At this time, the drive gear 42 is rotated in the clockwise direction (hereinafter referred to as 'electrostatic'), the perturbation piece 60 placed at any position of each end surface (from A to G) is the leftmost part of the A cross section (hereinafter referred to as 'the blackout'). (Hereinafter, the displacement in the left direction of the displacement of the perturbation piece on the cam is referred to as 'blackout'). This is referred to as an 'initial position setting process', and the document presence sensor 49 detects the document ( When 34) is detected, the starting position of the document feeder is set as the process to be executed. (Fig. 9 (a))

By the reverse rotational power of the drive gear 42, the second reduction gear 41 'is interrupted, and the cam gear 61 connected to the connecting piece 57 is rotated by a predetermined angle within the rotation range.

At this time, the cam gear 56 is rotated by a friction force between the second reduction gear 41 'and the cam gear 56, and the cam gear 56 is rotated at an initial position (far left of the cross section A) according to its rotational displacement. The perturbation piece 60 was moved to the end of the cross-section B end face of the cam 64, the cam gear 56 was turned away (Fig. 9 (b)), the drive gear 42 is There is a power outage.

The perturbation piece 60 is moved from the B point to the C point due to the power failure of the drive gear 42, and after the predetermined time has elapsed, the drive gear 42 is reversed again. The perturbation piece 60 is displaced to the right edge of the section D. At this time, the cam gear 56 is in contact with the idle gear 58 to transfer the power of the original driving motor 50 to the feed roller 31 so as to feed the document. Will be.

Here, the displacement of the perturbation piece 60 from the B end face of the cam gear 56 to the C end face is necessary to set the separation distance between the originals.

As shown in FIG. 4A, the cam gear 3 is engaged with the idle gear 16, and the driving force of the original driving motor 50 is the driving gear 42. It is transmitted to the second reduction gear 41, the cam gear 56, the idle gear 58, the belt 59 by the driving force, and thus the driving force is transmitted to the feed roller 31.

When the paper feed roller 31 is rotated, the friction force of the document separation piece 65 provided to contact the paper feed roller 31 and its lower side among the documents 34 loaded on the document loading table (not shown in the drawing), The single document 34 is started to be fed by the rotation speed of the document feed roller 31 (hereinafter referred to as V12), and the fed document 34 is detected by the document edge detection sensor 49 for a predetermined time. After elapsed, the image recorded on the document 34 is read by the optical unit. At this time, the perturbation piece 60 is moved to the position on the far left side of the cross section D. (Fig. 9 (e)).

Then, when the tip of the document 34 moves between the relay rollers 39, the drive gear 42 rotates forward, and the cam gear 56 in contact with the idle gear 58 is separated and moved to the left. It is rotated by a range, and the perturbing piece 60 rises from the cross section D to the cross section E to the cross section G and is moved back to the cross section A which is the initial position.

After the reading is completed, the document 34 continues to be discharged at a rotational speed of the relay roller 39 (hereinafter, V13).

At this time, when the original driving motor 50 is reversed, the perturbation piece 60 is moved from the A end face to the B end face so that it is no longer moved, and the cam gear 56 is the second reduction gear 41 '. ) Is in a state of being in line with

At this time, since the cam gear 56 and the idle gear 58 are in a separated state as in the initial state (Fig. 9 (b)), the driving force is not transmitted to the paper feed roller 31 and is stopped. The second document 34 'is in an unpaid state.

As described above, the paper is fed by one cycle driving of the cam gear 56 by the forward and reverse rotational power of the drive motor, and the transfer state of the second original will be described with reference to FIG.

(A) to (e) of FIG. 10 are functional state diagrams showing the inter-document transfer state of the document transmission unit according to the present invention, (A) is a state diagram showing the position of the cam gear and the transfer of the document, (B) is a cam section It shows the position of the perturbation piece perturbed in.

As shown in the figure, when the original driving motor 50 is moved to the C cross section by the electromotive drive 50 located in the cross-section B, the original driving motor 50 is reversed to the perturbation piece 60 ), The driving force is transmitted in the D cross-section position to feed the second document 34 '(Fig. 10 (a) and (b)).

At the moment when the tip of the second document 34 'is moved between the relay rollers 39, the perturbation piece 60 moves from the D cross section to the A cross section by the forward rotation of the drive gear 42. The relay roller 39 is rotated in the direction opposite to the original ejection direction to stop the front end of the original with a slight deflection. (Fig. 10 (c) in Fig. 10)

Subsequently, the relay roller 39 is rotated again in the document discharge direction by the reversal of the drive gear 42, and the perturbation piece 60 moves from the A cross section to the B cross section.

At this time, the cam gear 56 and the second reduction gear 42 'are in a straight line as in the case of FIG. 9 (b), and the moment when the document 34' leaves the paper feed roller 31 ( Since the cam gear 56 is separated from the idle gear 58 at the far left position of the cross section D, the driving force of the drive gear 42 is stopped without being transmitted to the document feed roller 31. Originals are fed only by the rollers 39 (Fig. 10 (d).

Therefore, a separation distance for separation from the next document 34 'is formed.

Subsequently, when the medium of the original is finished by the relay roller 39, the perturbation piece 60 moves from the C cross section D to the D cross section in the power transfer state to the document feed roller 31. It is ready for feeding. (Fig. 10 (e))

On the other hand, the recording sheet loaded in the recording sheet cassette 47 is rotated by the recording sheet feeding motor 46 driven by an external recording signal (not shown in the drawing) to rotate the recording sheet feeding roller 44 to record the recording sheet. Separately transport each.

The contents described so far include the feed / absence detection sensor 40 which detects the presence or absence of the document and recording paper conveyed from the paper feed and read-out part and the recording paper conveying part, and the paper feed roller 31 and the paper feed roller 44. The originals and recording papers are conveyed through the relay rollers 39, and the discharge paths of the originals and the recording paths of the recording papers are discharged to the discharge rollers 38 through the same transfer paths.

Here, as shown in FIG. 6, when the document is discharged (solid line is shown in the drawing), the originals passing through the discharge roller 38 with the solenoid 51 turned off are passed through the differential piece 55. When the recording sheet is discharged (shown by dotted lines in the drawing), the solenoid 51 is turned on, and the differential piece 55 is oriented about the hinge 52 so that the recording medium guide 54 is discharged. It is discharged past.
