Abstract

PURPOSE:To provide a paper delivery apparatus with which the paper is caught easily after printing with its curling tendency corrected. CONSTITUTION:A paper delivery port 11, warped in the breadthwise direction of paper 2, is provided to one side of a printing equipment main body 1 which incorporates a paper carriage passage through which long paper 2 wound up in a roll shape is carried, a paper feeding part, a printing mechanism and a cutter. A sleeve-shaped delivery passage 13, connected at its one end to the end part of the paper carriage passage and in a section which resembles closely to the shape of opening of the paper delivery port 11 as it approaches the delivery port 11, is provided. The paper 2, after printing is made thereon, is warped breadthwise gradually as it is fed through the delivery passage 13, and is discharged straight through the paper delivery port 11 without being slackened.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper discharge device used in a printing machine.

[0002]

2. Description of the Related Art Conventionally, there is a printing apparatus which prints on a sheet of paper wound in a roll and cuts the printed sheet with a cutter, such as when issuing a receipt. In such a printing device, as shown in FIG. 4, in order to take out the printed paper 2, the printing device main body 1
A linear sheet discharge port 15 is formed on the surface of the sheet.

[0003]

Since the paper 2 wound in a roll is ejected from the paper ejection port 15 with a curl, the paper 2 curls and is difficult to take out.
Such a phenomenon appears as a particularly remarkable phenomenon when the paper 2 having a weak stiffness is used or when the winding diameter of the paper 2 is small.

[0004]

According to the present invention, a paper feed path for feeding a long sheet wound in a roll, a paper feed section and a printing mechanism provided in the paper feed path are built-in. A printing device main body is provided, a cutter is provided on the downstream side of the printing mechanism in the paper conveyance path, and a discharge port curved in the width direction of the paper is provided on one surface of the printing device main body, and one end of the paper conveyance path is provided. A cylindrical paper discharge passage having a cross-sectional shape that is connected to the end portion and gradually approaches the shape of the opening surface of the paper discharge opening as it goes toward the paper discharge opening is provided.

[0005]

[Function] The printed sheet can be discharged little by little by curving in the width direction of the sheet by the sheet discharge path, and thus the sheet can be discharged straight from the curved sheet discharge port. It is possible to eject the paper, which makes it easy to grip the paper after printing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. The same parts as those described in FIG. 4 will be described using the same reference numerals. As shown in FIG. 3, the printing apparatus main body 1 is provided with a paper transport path 3. At one end of the paper transport path 3, a supply shaft 4 for winding and holding the long paper 2 in a roll shape is provided. Further, the paper transport path 3 is provided with a plurality of pairs of feed rollers 5, which are paper feed units, a printing mechanism 6, and a cutter 7. The printing mechanism 6
Is a carrier 8 held reciprocally along the width direction of the paper 2 and a print head 9 mounted on the carrier 8.
And a platen 10 facing the print head 9.

Next, as shown in FIG. 1, a discharge port 1 curved in the width direction of the sheet 2 is provided on the front side of the printer main body 1.
1 is formed. Note that, as shown in FIG. 2, instead of the paper ejection port 11, a paper ejection port 12 curved in a wave shape may be formed. The paper discharge port 11 or 12 and the paper transport path 3
Is connected to the end of the sheet by a sheet discharge passage 13 having a rectangular tube shape. The discharge path 13 has an opening surface 14 having a relatively large opening area at one end on the printing mechanism 6 side.
4 is formed in a rectangular tube shape whose cross-sectional area approaches the opening area of the paper discharge port 11 or 12 from the opposite side.

In such a structure, the paper 2 held by the supply shaft 4 is printed by the printing mechanism 6, conveyed by the feed roller 5, and gradually fed by the paper discharge passage 13.
11 or 12 that is curved while being curved in the width direction of the sheet
Is ejected from. Therefore, it is possible to apply tension to the paper 2 and eject the paper straight from the paper ejection port 11 or 12.
This makes it easy to grip the paper 2. The sheet 2 is cut by the cutter 7 when it is discharged for a certain length.

[0009]

According to the present invention, there is provided a main body of a printing apparatus having a paper feed path for feeding a long sheet wound in a roll shape, a paper feed section provided in the paper feed path, and a printing mechanism. A cutter is provided on the downstream side of the printing mechanism in the paper transport path, and a discharge port curved in the width direction of the paper is provided on one surface of the main body of the printing device, and one end is connected to the end portion of the paper transport path. Since a cylindrical paper discharge passage having a cross-sectional shape that gradually approaches the shape of the opening surface of the paper discharge outlet is provided toward the paper discharge outlet, the printed paper is gradually moved in the width direction of the paper by the paper discharge passage. It is possible to eject paper from a curved ejection port while curving it. Therefore, it is possible to tension the paper and eject it straight from the ejection port, which makes it easy to grip the printed sheet. Has the effect of being able to.
