A paper storage unit for storing the blocked receipt paper is formed, and the paper storage unit is arranged at a position between the cutter and the discharge port. A taper portion for guiding the receipt sheet into the sheet storage section is provided.

[Action]

In the above-described configuration, if the receipt paper is pressed from the outside of the discharge port by the operator or the like while the receipt paper is discharged to the discharge port by driving the platen and the drive roller by the motor (not shown), the receipt paper cannot be discharged. The subsequent portion of the receipt paper starts to bend and bend in a direction in which it is easily bent due to curling when the receipt paper is in a roll shape before the discharge port. Further, since the receipt paper is provided in the paper feeding path of the receipt paper in the direction in which the receipt paper is easily bent due to the curl of the receipt paper in the feeding direction, the paper entrance and exit into the paper storage part. From, it is guided to the taper part provided in front of the discharge port and escapes,
The paper guide is stored in a U-shaped bent state along the bottom surface extending from the paper guide and the top surface composed of the apparatus cover. Further, the leading end of the U-shaped receipt paper is prevented from entering by the leading end surface and does not overflow from the paper storage unit.

For this reason, the receipt paper does not become jammed in the feeding path of the apparatus, and the receipt paper that has escaped to the paper storage section does not overflow from the paper storage section. It is possible to prevent the slack in the sheet and prevent the print deviation due to the slack. Further, it is possible to prevent the occurrence of a jam caused by the receipt paper which is prevented from being discharged from being caught on the tip of the print head or being caught by the driving roller.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a side sectional view of a main part showing a discharge mechanism of a receipt sheet processing apparatus according to the present invention.

In the figure, 1 is a receipt paper that is rolled and stored in a roll shape, 2 is a platen, 3 is a pinch roller that presses the receipt paper 1 against the platen 2, and 4 is a print head that is provided facing the platen 2. Then, the receipt paper 1 wound around the platen 2 is printed.

A pair of drive rollers 5 are provided above the platen 2 and the print head 4 and are driven by a motor (not shown).
Driven together with the receipt paper 1 to rotate in the direction of the arrow shown in the figure.
To supply.

Reference numerals 6 and 7 denote paper guides arranged above the pair of drive rollers 5, and a stamp 8 is arranged at the rear of the back surface of either one of the paper guides 6 and 7, and a stamp 8 is provided as necessary. The receipt paper 1 that has been projected and fed in the direction of the other paper guide is stamped with the store name, address, and the like. In this case, the other paper guide provided oppositely also serves as a platen.

9 is a cutter provided above the paper guides 6 and 7,
This is for cutting the printed portion of the receipt paper 1 on which printing, marking, etc. have been made.

Reference numeral 10 is a cover that covers the upper side of the apparatus, and has a discharge port 11 for discharging the receipt paper 1.

Reference numeral 12 denotes a paper storage portion provided between the discharge port 11 and the cutter 9, and the paper storage portion 12 is positioned in a direction in which the receipt paper is easily bent by curling when the paper is in a roll shape. Extend the upper end of the paper guide 7 along the cover 10 of the device by a length that can accommodate one receipt piece, and use this as the bottom part, and then fold the extended tip part to the cover 10 side. It is bent, and this is used as an end face portion, and the cover 10 is used as an upper face portion.

Further, among the projecting portions 11a formed to project inside the discharge port 11, the projecting portion 11a on the side of the paper storage portion 12 is cut out to form a taper portion 11b below, and the receipt paper 1 is stored in the paper storage portion 12. The shape is such that it can be easily inserted, and the paper inlet / outlet of the paper storage unit 12 is formed.

Incidentally, the receipt paper 1 in this configuration, after passing between the platen 2 and the pinch roller 3 as in the conventional case, is guided to the print head 4 along the outer periphery of the platen 2, and from here, between the pair of drive rollers 5 and. It is set in the paper feed path between the paper guides 6 and 7 and the cutter 9 to the discharge port 11.

Next, the operation of the above-described configuration will be described. First, printing is started by the print head 4, and the platen 2 and the drive roller 5 are rotationally driven in the arrow direction by a motor (not shown),
A line feed during the printing operation or the receipt paper 1 after printing is fed. Further, when the printing of the first line is performed or before that, the stamp 8 is driven to imprint a store name, an address, etc. at a predetermined position on the receipt paper 1.

During this processing operation, that is, when the operator or the like carelessly presses the receipt paper 1 discharged from the discharge port 11 with his / her finger before cutting by the cutter 9, Subsequent receipt paper 1 that can no longer be discharged begins to sag in the vicinity of the discharge port 11, folds in a direction in which it easily bends due to curling when it is in a roll shape, and bends along the taper portion 11b at the entrance and exit of the paper storage unit 12. It escapes to the paper storage unit 12, enters along the bottom surface and the top surface of the paper storage unit 12, and is stored in a U-shaped bent state as shown in FIG. Since the front end of the paper storage portion 12 is closed by the end surface portion, the receipt paper 1 bent in a U shape does not enter from the end surface portion first, and thus overflows around the paper storage portion 12. There is no such thing.

After that, the recorded portion of the receipt paper 1 is cut by the cutter 9 into one receipt piece, which is pulled out from the paper storage unit 12 by the operator.

The leading end portion of the receipt paper 1 in the apparatus after being cut is fed along the paper guide 6 located at a position facing the paper guide 7 having the paper storage portion 12 formed by curling when the paper is rolled. Therefore, it does not enter the entrance / exit of the paper storage unit 12.

[Effect of device]

As described above, according to the present invention, in a receipt paper processing device that pulls out one end of receipt paper stored in a roll shape and feeds it to an ejection port for processing, the receipt paper is fed to a feeding path of the receipt paper. The end portion of the paper guide, which is located in the direction in which it is easily bent due to curling when it is in a roll shape, extends along the cover of the apparatus for a predetermined length with a predetermined gap between the end and the end. The existing portion is the bottom portion, the tip side of this bottom portion is bent to the device cover side, and this is surrounded by the end face portion and the three faces with the device cover portion as the top face, and the discharge is prevented from the discharge port. A paper storage unit for storing the receipt paper is formed and disposed at a position between the cutter and the discharge port, and further, at the paper inlet / outlet of the paper storage unit, the receipt is sent from the discharge port into the paper storage unit. Led paper By providing the taper part, the operator, etc. may try to remove the receipt paper that is being ejected from the ejection port in a hurry and carelessly press the receipt paper before cutting from the outside of the ejection port with a finger etc. so that it cannot be ejected. If
The receipt paper that cannot be discharged is released into the paper storage unit and stored.

Therefore, there is no slack between the pinch roller and the drive roller as in the conventional case, it is possible to prevent the print misalignment caused by this, and also the loose receipt paper is caught at the tip of the print head, It is possible to prevent the occurrence of jam caused by being caught in the driving roller and to obtain a reliable discharging mechanism.

Further, since this paper storage section is arranged in a direction in which it easily bends with respect to the paper feed path due to winding when the receipt paper is in a roll shape, the receipt paper is easily moved to the paper storage section side. The paper is folded and escapes from the paper inlet / outlet, and is stored while being bent in a U shape along the bottom surface and the top surface forming the paper storage unit, and jams or sags in the paper feeding path. Can be reliably prevented.

Further, since the receipt paper which has escaped into the paper storage portion is stored inside the paper storage portion surrounded by the three surfaces of the bottom surface portion, the end surface portion and the top surface portion, it overflows to the outside. Therefore, there is no possibility that another mechanism inside the apparatus, that is, the stamp, the driving roller, the print head, or the like will be entangled or wound around and cause a new secondary failure.

Further, the paper storage portion is arranged along the device cover from the paper inlet / outlet provided directly below the discharge port, so that the escape portion for the receipt paper is secured without increasing the size of the device.
