As shown in FIGS. 3 and 4 and 6A and 6B, the folded paper 101 loaded in the paper storage box 110 is inserted into the first guide 141 which is the beginning of the paper transfer path 103. . The first guide 141 extends to the printer 120 to guide the front end of the paper 101 to the printer 120.

The printer 120 is positioned at an upper end of the first guide 141, and a paper feed roller 151 is mounted at the lower end of the first guide 141 to correspond to the printer 120. The paper feed roller 151 rotates by the first motor 181 and advances the paper 101 printed by the printer 120 to the front.

The paper 101 printed by the printer 120 is advanced to the cutter 130 along the second guide 142. The paper is cut into sheets of paper 101c from the folded papers 101 connected as one by the operation of the cutter 130.

On the other hand, the third guide 143 is located in front of the cutter 130, the fourth guide 144 is located at the lower end of the third guide 143, the fifth guide in front of the fourth guide 144. 145 extends to the paper outlet 104. The first feed roller 161 is mounted to the rear end of the third guide 143, and the second feed roller 162 is mounted to the front end of the third guide 143, and the third feed roller (126) is attached to the rear end of the fifth guide 145. 163 is mounted and the discharge roller 152 is mounted at the tip.

Here, the first feed roller 161, the second feed roller 162, the third feed roller 163, the discharge roller 152 is located on the top of the guides (143, 145), each of these rollers ( In response to 161, 162, 163, and 152, idle rollers 171, 172, 173, and 174 are mounted below the guides 143 and 145 to freely rotate. The first conveying roller 161, the second conveying roller 162, the third conveying roller 163, the discharge roller 152 is rotated so as to advance the sheet 101c in contact with the sheet 101c, the corresponding Idle rollers 171, 172, 173, 174 serve to support the paper 101c.

Accordingly, the paper advanced by the paper feed roller 151 is caught by the first feed roller 161 and the idle roller 171 corresponding thereto, and the paper is rotated by the first feed roller 161 so that the paper is rotated by the third guide 143. Advance along

As shown in FIG. 4, a fourth guide 144 is positioned below the distal end of the third guide 143, and the fourth guide 144 is movably mounted so that the distal lower end of the third guide 143 is opened. It is closed.

Meanwhile, the fourth guide 144 is fixed to the guide shutter 191, and the guide shutter 191 is connected to the second motor 182. Therefore, the guide shutter 191 is rotated by the driving of the second motor 182, and the fourth guide 144 is also moved in accordance with the turning of the guide shutter 191, while opening the lower end of the third guide 143. Or close it.

Meanwhile, a pusher 193 is mounted at an upper portion corresponding to the fourth guide 144, and the pusher 193 is connected to the rotation shaft of the second feed roller 162 by a torsion spring 195. Here, the torsion spring 195 provides an elastic force to push the pusher 193 toward the fourth guide 144.

Therefore, when the fourth guide 144 closes the tip of the third guide 143, the pusher 193 is positioned in contact with the top surface of the fourth guide 144, and the fourth guide 144 moves. When opened, the vehicle pivots downward along the fourth guide 144 that is opened.

As described above, when the pusher 193 pivots downward, when the fourth guide 144 moves in the original position, that is, in the direction in which the lower end of the third guide 143 is closed, the pusher 193 moves to the fourth guide. It is pushed upward by 144 and is eventually positioned in contact with the upper surface of the fourth guide 144.

Even if the pusher 193 is in contact with the upper surface of the fourth guide 144, the elastic force of the torsion spring 195 is not so great that the tip of the paper 101c advancing by the second feed roller 162 is pusher ( Passes between 193 and the fourth guide 144.

Meanwhile, the paper 101c advanced through the third and fourth guides 143 and 144 enters the fifth guide 145, and the third feed roller 163 mounted at the rear end of the fifth guide 145. And the idle roller 173 corresponding thereto. When the third feed roller 163 rotates in this state, the front end of the sheet 101c is brought into contact with the discharge roller 152 in the stopped state while advancing along the fifth guide 145.

When the discharge roller 152 is rotated while the tip of the paper 101c is in contact with the discharge roller 152 as described above, the tip of the paper 101c is discharge roller 152 and the idle roller 174 corresponding thereto. The paper is discharged out of the printing apparatus 100 through the paper outlet 104.

5B and 6B, the first feed roller 161, the second feed roller 162, and the third feed roller 163 are connected by gears to interlock by the third motor 183. The discharge roller 152 is connected to the gear to rotate by the fourth motor 184.

Meanwhile, as shown in FIG. 5B, a sensor mounted on the printing apparatus 100 and a function thereof will be described.

As shown in FIG. 5B, the first guide 141 is equipped with a paper entry sensor 201 detecting a paper entry. The printer 120 is equipped with a thermal print head open / close sensor 202 to detect whether the thermal print head assembly is opened or closed when a paper jam occurs.

In addition, the mark sensor 203 is mounted between the cutter 130 and the printer 120 to detect the mark printed on the back of the paper 101 to check the position of the paper 101. When the mark of the sheet 101 is detected by the mark sensor 203, the sheet 101 is stopped and the cutter 130 is operated to cut the sheet 101.

In addition, a first paper path sensor 204 is mounted on the third guide 143 to check whether the paper 101c is in the third guide 143, and a shutter opening / closing sensor 205 is mounted on the guide shutter 191. The guide shutter 191 operates to detect whether the fourth guide 144 is opened or closed.

In addition, the paper eject sensor 206 is mounted between the front end of the third guide 143 and the rear end of the fifth guide 145 so that the rear end of the paper 101c positioned in the fifth guide 145 is opened. By detecting whether the guide 143 is drooping downward of the tip, it is detected whether residual paper is present during paper discharge.

A second paper path sensor 207 is mounted on the fifth guide 145 to detect whether there is paper in the fifth guide 145, and a paper recovery sensor 208 is mounted on the paper discharge port 104 to discharge the paper outlet. At 107, it is detected whether paper has been ejected.

Hereinafter, the operation relationship of the printing apparatus configured as described above will be described.

4 and 5b and 6a and 6b, the user inserts the tip of the paper 101 loaded in the paper storage box 110 into the first guide 141 and then pushes it. Then, the paper entering sensor 201 detects the paper 101 entered and operates the first motor 181 to rotate the paper feed roller 151. When the user keeps pushing the front end of the paper 101 into the first guide 141 and the front end of the paper 101 touches the rotating feed roller 151, the front end of the paper 101 is fed into the paper feed roller 141. In order to advance to the printer 120.

On the other hand, the paper 101 is printed by the printer 120 while the paper 101 advances to the printer 120 by the rotation of the paper feed roller 151. The front end of the printed sheet 101 is continuously transferred from the second guide 142 to the third guide 143 by the rotation of the paper feed roller 151.

The cutter 130 operates to cut the paper 101 while the front end of the paper 101 enters the third guide 143 by the predetermined length and is bitten by the first feed roller 161. Here, the fold 102 of the paper 101 operates at the rear end of the fold 102 past the cutter 130, and at the time of operation, the mark sensor 203 is printed on the back of the paper 101. When the feed roller 151 and the first feed roller 161 are stopped, the cutter 130 operates.

After the paper 101c is cut by the cutter 130, the first feed roller 161 is rotated to move the paper 101c held along the third guide 143.

Meanwhile, the first paper path sensor 204 mounted on the third guide 143 senses the paper 101c passing by. If the paper 101c does not advance after a predetermined time has elapsed, it is determined that a paper jam has occurred earlier, and the printing apparatus 100 is stopped.

When the paper 101c advances along the third guide 143, the fourth guide 144 is in a state in which the tip of the third guide 143 is closed, and the paper 101c transferred along the third guide 143. ) To support the fifth guide 145.

When the front end of the paper 101c enters the fifth guide 145 and the front end of the paper 101c contacts the discharge roller 152, the second motor 182 drives to guide the guide shutter 191. Turn around. Then, the lower end of the third guide 143 is opened while the fourth guide 144 fixed to the guide shutter 191 moves along the guide shutter 191.

As the fourth guide 144 is moved and the lower end of the third guide 143 is opened, the pusher 193 is pivoted downward by the elastic force of the torsion spring 195, and accordingly, FIG. ), The rear end of the paper 101c is bent to the lower portion of the third guide 143 by the pusher 193 through the opening to form a loop. At this time, the rear end of the paper 101c continues to be advanced by the rotation of the second feed roller 162. As a result, as shown in FIG. 4C, the rear end of the paper 101c is opened with the third guide ( 143) sag down.

Looking at the sheet of paper 101c 'positioned in the fifth guide 145 in this state, the tip of the sheet 101c' is positioned in contact with the discharge roller 152, and the middle of the sheet 101c 'is the fifth. Extending rearward along the guide 145, the rear end of the sheet 101c 'sags below the rear end of the fifth guide 145. As shown in FIG. In this way, even if the papers 101c 'and 101c "of A4 size (210mm * 297mm) are placed on the 5th guide 145, since the 3rd feed roller 163 is bitten, it is the paper 101c' and 101c". Do not flow down the rear end of the fifth guide 145, that is, the tip of the opened third guide 143.

As described above, in the state where one sheet of paper 101c 'is positioned in the fifth guide 145, the second motor 182 drives to restore the guide shutter 191 to its original position. Then, the fourth guide 144 closes the lower end of the opened third guide 143.

In this state, when the printing apparatus 100 is set to eject the sheet by sheet, the discharge roller 152 is driven, and the sheet 101c 'positioned in the fifth guide 145 is discharged from the sheet 104. Is discharged through.

However, when the printing apparatus 100 is set to eject a plurality of receipts, the printing apparatus is restarted as described above while the one sheet of paper 101c 'is positioned on the fifth guide 145. One sheet of paper 101c "is stacked on top of the first sheet of paper 101c '.

The plurality of sheets 101c 'and 101c "stacked on the fifth guide 145 are neatly stacked by their ends being in contact with the discharge roller 152, and the discharge roller 152 rotates in this state. A plurality of stacked sheets 101c 'and 101c "are discharged at once.

On the other hand, when comparing the 2nd feed roller 162 and the 3rd feed roller 163, the pressing force which the 2nd feed roller 162 presses the paper 101c "is larger than the 3rd feed roller 163. FIG. The reason for this is to minimize the friction generated between the sheets 101c 'and 101c "as the next sheet 101c" enters the state where the single sheet 101c' is positioned in the fifth guide 145. As a result, the paper 101c 'may be pushed by the friction of the paper 101c "entering the fifth guide 145 after the first paper 101c', thereby crushing or tearing the paper. .

On the other hand, if the paper 101c is not detected by the second paper path sensor 207, it is recognized that all of the paper covering the fifth guide 145 is discharged, and at this time, the paper 101c is applied to the paper eject sensor 206. When detected, only a part of the plurality of sheets is recognized as being discharged, and the printing apparatus 100 is stopped.

In addition, the paper recovery sensor 208 mounted on the paper outlet 104 detects whether the paper 101c has passed and recognizes that the customer does not take the paper when the paper is detected even after a certain time elapses, and the discharge roller 152. ), The paper located over the paper outlet 104 is recovered into the printing apparatus 100. At this time, the discharge roller 152 and the third feed roller 163 is reversely rotated together with the fourth guide 144 is moved to open. As a result, the sheet 101c falls off the tip of the opened third guide 143 and is recovered.

On the other hand, reference numeral 105, which is not described in Figure 5a is a case for protecting the printing apparatus 100, reference numeral 209, which is not described in Figure 5b is a discharge opening and closing sensor, it is opened to remove the jammed paper jams The sensor to detect the opening and closing of the outlet.

In addition, although the printing apparatus according to the present invention described above has described that the paper has an A4 size, a paper having a size of 1/3 (210mm * 99mm) or 2/3 (210mm * 198mm) with respect to the length of A4 is used. Even if it can express the object and effect of this invention fully.

In addition, in the foregoing, only the foldable paper is mentioned as the paper of the printing apparatus according to the present invention. Even if the rolled paper is rolled like a roll instead of the foldable paper, the object and effect of the present invention can be sufficiently expressed.

As described in detail above, in the printing apparatus of the present invention, since the rear end of the paper is bent and positioned not in the entry direction of the other paper while the leading edge of the cut paper is stagnant, the leading edge of the paper entering later and the paper entering the paper This solves the problem of paper jam which occurs when the rear end of the cable is interfered with and folded around the folding part.

In addition, the printing apparatus of the present invention is capable of outputting a paper on which a large amount of information is printed during the discharging process by discharging the stacked paper at a time while one to many sheets are stacked neatly before the printed paper is discharged. In addition, as a number of sheets are arranged, the paper is entangled during the discharging process.

In addition, the printing apparatus of the present invention can use a variety of papers if the length satisfies only the length from the third feed roller to the pusher and the shutter even when using non-standard paper, thereby widening the choice of printing paper.

In addition, the printing apparatus of the present invention is configured such that the printed paper goes straight from the printer to the paper discharge port without bypassing, thereby minimizing the paper transport path. Therefore, there is an advantage that it can minimize the time to print and discharge on the paper.

The technical idea of the printing apparatus of the present invention has been described above with the accompanying drawings, but this is by way of example only for describing the best embodiment of the present invention and not for limiting the present invention.
