Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper processing apparatus for feeding and discharging paper used for a printer, a scanner, etc., and more particularly to a paper processing apparatus having a plurality of paper feeding and discharging means. The present invention relates to a leaf processing device. 2. Description of the Related Art In recent years, OA equipment in offices has been known as FAX,
The use of composite paper such as copying and printers and the conversion of paper into plain paper in consideration of resource recycling are progressing. Under these circumstances, attention has been paid to a device that integrates a document reading unit (hereinafter, referred to as a “scanner”) and an ink jet printer and can realize four functions of a plain paper FAX, a digital copy, a computer printer, and a scanner. In particular, in order to reduce the installation space on the desk, the printer and scanner must be of a sheet-through type (a sheet-shaped recording paper or document is passed one by one to a predetermined area), It is desirable that the paper passing and the paper passing to the scanner coincide when projected from above. In consideration of the handling of paper by the printer and the scanner, the printer uses a front-side paper feed so that the print result can be seen, and the scanner uses a front-side paper feed so that the original can be easily set in the paper feed port. Layout. For this reason, if a printer output tray and a scanner paper feed tray are provided in the apparatus as in the related art, two trays are installed in front of the user, and one of the trays is installed in the air. As a result, he leaned to the front and jumped out, resulting in a feeling of oppression, which hindered his work on the desk. In addition, the paper ejection tray of the printer is eliminated,
If the paper is discharged onto the paper feed tray of a scanner that is installed almost horizontally near the desk top, there is no feeling of pressure, and if the desk is used as a part of the paper feed tray, the length of the paper feed tray will be shorter. It is possible to supply a very compact device with the minimum necessary. However, if the paper feed tray of the above-described scanner is shared with the printer paper discharge tray without the printer paper discharge tray disposed above the scanner, the paper size of the printer is reduced. And the paper size of the scanner, the printed paper may be fed from the scanner paper feed port together with the document read. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and it is possible to inexpensively and reliably mix print-out paper and a read original by improving the arrangement of a printer and a scanner and improving some parts of the scanner. It is another object of the present invention to provide a sheet processing apparatus capable of preventing erroneous reading. In order to achieve the above object, the present invention provides a tray for holding a first sheet supplied to a recording apparatus, and a tray for supplying a first sheet from the tray to the recording apparatus. A first sheet supply conveyance path, and a second sheet, which is above the supply conveyance path and is image-recorded by a recording unit.
And a discharge conveyance path for conveying and discharging the sheet in a direction opposite to the conveyance direction in the supply conveyance path, and the first sheet in a direction on the tray and substantially orthogonal to the supply direction of the first sheet. A pair of restricting means for restricting both side end positions of the sheet, wherein a conveyance reference of the second sheet is a left end of the second sheet with respect to a discharge conveyance direction of the second sheet; The second sheet, which is located outside the regulating unit on the right side with respect to the supply / conveying direction of the first sheet and is discharged from the discharge / conveyance path to the outside of the recording apparatus, is disposed on the regulating unit of the tray. The first sheet held on the tray is shifted and accumulated. In the present invention configured as described above, the reference for conveying the second sheet is the left end of the second sheet with respect to the discharging and conveying direction of the second sheet, and Since the first sheet is outside the right regulating means with respect to the supply / conveyance direction of the first sheet, when the second sheet is discharged out of the recording apparatus from the discharge conveyance path, the second sheet is placed on the right regulating means on the tray. It accumulates shifted from the first sheet. For this reason, the first sheet held via the regulating means on the tray and the second sheet discharged onto the first sheet are not mixed, and the two sheets can be surely sorted. Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an external perspective view showing an embodiment of the paper sheet processing apparatus of the present invention, and FIG. 2 is a longitudinal sectional view of the paper processing apparatus of FIG. Referring to FIGS. 1 and 2, a printer unit and a scanner unit are arranged inside a housing 1 of the paper sheet processing apparatus according to the present embodiment in such a manner that the paper passage area is divided into upper and lower parts. First, the scanner section will be described. The scanner unit is located at the lowermost part in the housing 1,
A paper feed tray 2 for feeding a document to be read protrudes from a side facing the user during use (hereinafter, referred to as “front of the apparatus”). A paper width guide (left) 3 and a paper width guide (right) for restricting a width direction substantially perpendicular to the traveling direction of the document and preventing the document from being transported in an oblique state are provided on the paper feed tray 2.
4 is slidably mounted. The paper width guide (left) 3 and the paper width guide (right) 4 are provided with a well-known mechanism that slides left and right with reference to the center of the guide width, so that the paper width guide (left) 3 and the paper width guide (right) By moving one of the four by hand, the other also moves. FIG. 3 shows a mechanism of the paper feed tray 2 having a paper width guide (left) 3 and a paper width guide (right) 4 as viewed from the back side thereof. The paper width guide (left) 3 is configured such that its bosses 5 and 6 are fitted in the left groove 7 of the tray 2 so as to be slidable right and left and connected to the bosses 5 and 6 with the tray 2 interposed therebetween. It is fixed integrally with the rack 8. On the other hand, the paper width guide (right) is similarly moved to the rack 11 via the bosses 9 and 10.
And is slidably fixed integrally with it. Since the rack gears of the racks 8 and 11 are meshed with the gear 12 rotatably supported at the center of the back surface of the tray, when one rack slides, the other rack slides via the gear 12. I have. That is, when one of the paper width guide (left) 3 and the paper width guide (right) 4 is slid, the other moves at the same distance in the opposite direction. Returning to FIG. 2, the document to be read whose width is regulated by the above mechanism is separated one by one by a separation pad 13 and a separation roller 14 arranged inside the housing 1, and then the scanner conveyance roller pair is separated. 15 and 16. The scanner transport roller pair 15, 16 is provided with a reading sensor 17.
It is rotationally driven by a motor (not shown) so that the original is conveyed at a predetermined reading speed. The reading sensor 17 is composed of a light source and a photoelectric conversion element array, and reads light / dark (monochrome) information of a document moving at a predetermined speed by converting it into an electric signal. On the side opposite to the reading sensor 17 across the document, there is a white platen 18 for preventing the document from floating and determining the reference brightness of white for reading, thereby maintaining the reading quality. Further forward, scanner discharge roller pairs 19 and 20 are provided, and a document is discharged to a scanner discharge tray 21 provided at the rear of the housing 1. Next, the printer section will be described. The printer section is located above the above-described scanner section, but the paper traveling direction is opposite to that of the scanner section. A paper feed tray 23 is provided at the rear of the housing 1, and a well-known claw separation is performed by a half-moon roller 24 and a claw (not shown) on one side end of the paper in the tray 23. The paper is sent to the pair of printer transport rollers 25 and 26. The pair of printer transport rollers 25 and 26 guide the paper onto a print platen 27 facing the inkjet head 28, transport the paper for each print width W of the inkjet head 28, and wait for the next print. The ink-jet head 28 can reciprocate along a pair of slide shafts 29 and 30 supported in parallel to the left and right sides of the housing 1 (in FIG. 2, in a direction perpendicular to the paper surface). A driving force is given by the belt, and printing is performed by flying ink droplets on the paper surface with a printing width W while moving from the right side to the left side of the housing 1 shown in FIG. The printing of the width W and the conveyance of the paper of the width W are alternately repeated, and after all the printing of the desired image information is finished, the paper is discharged out of the housing 1 by the pair of printer discharge rollers 31 and 32. FIG. 4 shows the positional relationship of the paper supply / discharge ports of the apparatus of this embodiment as viewed from the direction A in FIG. The ink-jet head 28 caps the nozzle portion at the time of non-printing in order to prevent the ink from drying and clogging the nozzle portion at the tip, or discharges ink from all the nozzles every several times of printing. It is necessary to take measures such as Therefore, as shown in FIG. 4, this kind of ink clogging prevention mechanism 33 is disposed outside the printing area on the printing start position side in order to minimize the loss of time required for printing. The printing start position is fixed as a one-sided conveyance reference so that loss does not increase. As shown in FIG. 4, the paper is fed from the scanner section by the paper feed tray 2 to the maximum letter width of 148 + 2 = 21 mm from the minimum A5 width of 148 mm on the basis of the center.
Covers paper sizes up to 8 mm. On the other hand, the paper is conveyed and discharged on the basis of the right side B in FIG. 4 in the printer section, but the paper size covers 148 to 218 mm from A5 to letter like the scanner section. The transport reference B of the printer unit is the maximum paper size (218 mm) or the minimum paper size (14 mm) of the scanner unit.
8 mm), it is arranged outside the position of the right guide 4. Further, the position of the left end (the opposite side to B) of the printer maximum paper size (or minimum paper size) is located inside the left guide 3 when the scanner unit has the maximum paper size (or minimum paper size). As a result, the paper discharged from the printer unit falls on the right guide 4 of the scanner unit. FIG. 5 shows a side view of the apparatus from which the paper has been discharged from the printer unit. As shown by a two-dot chain line in FIG. Since the paper is accumulated at a position shifted from the original 35, it does not mix with the original 35 transported to the scanner unit. If the print paper 34 falls over the right guide 4 and falls away from the housing 1, if the print paper 34 is dragged by the scanner document, it will be stopped by the right guide 4. I do not reach. Although the present embodiment has been described with reference to an example in which the printer unit is arranged at the upper part and the scanner part is arranged at the lower part, even when the scanner part is arranged at the upper part and the printer part is arranged at the lower part, the original discharged by the scanner is not affected. If it is configured to be deposited on the paper feed guide of the printer, it is possible to prevent the paper feed from being mixed. Further, in the paper transport standard, the scanner side is set as the center reference and the printer side is set as the one side reference. Conversely, the scanner side may be set as the one side reference and the printer side may be set as the center reference. As a criterion,
If the arrangement is such that the upper discharge paper is always deposited on the lower paper feed guide, the gist of the present invention is not spoiled. Although an example of the sheet processing apparatus according to the present invention has a scanner unit and a printer unit, a reading method of the scanner unit (for example, a CC using a reduction optical system) is used.
D reading etc.) and a printing method (for example, a laser beam method, a thermal transfer method, etc.) of the printer section are available, and a printing machine,
The present invention can be used with other devices such as a mark sheet reader. As described above, according to the present invention, the image is recorded by the recording means above the supply path of the first sheet supplied from the tray holding the first sheet into the recording apparatus. A discharge conveyance path for conveying and discharging the recorded second sheet in a direction opposite to the conveyance direction in the supply conveyance path is provided, and the second sheet is placed on a tray that regulates both side end positions of the first sheet. The first sheet held on the tray is shifted and deposited on the regulating means, so that the first sheet and the second sheet can be mixed inexpensively and reliably while being a compact device. The effect that it can prevent is produced.
