【発明の詳細な説明】 プリンタの紙送り装置に関するものである。[Detailed description of the invention] This invention relates to a paper feeding device for a printer.
従来、インクジェットプリンタばかりでなく、一般の紙

ローラ５の間で行なわれる。Conventionally, not only inkjet printers but also general paper feeding devices have been constructed as shown in FIG. Fa
In the figure, 1 is a head unit, 2 is a platen provided opposite to the head unit 1, 3 is a paper guide that guides the paper 4, 5 is a pressure roller that presses the paper 4 against the platen 2, and 6 is a pressure roller that pinches the paper 4. The paper 4 is wrapped around the platen 2 by Rare, pressure roller 5, and vapor pail 6.
The printing is performed between the paper pail 6 and the pressure roller 5.

とができなかった。In the conventional device configured in this way, it is necessary to sandwich the leading edge of the paper 4 between the paper pails 6, so there is an area where printing cannot be performed at the leading edge of the paper 4, and the trailing edge of the paper 4 is also left in the same way. Printing could only be done while the paper was held between the pressure rollers 5, and a margin was required at the rear end. Furthermore, since there is no paper guide in the printing section and the direction in which the paper is fed is curved,
In order to automatically feed the paper 4, it was necessary to provide another paper guide mechanism in this portion. Since the paper 4 is still bent and set along the platen 2, there is a drawback that if the jetting width of the ink jetted from the printing part 1 is made larger than a certain width, the printed characters will be distorted. Furthermore, in impact printers, the platen 2 on the front of the carriage is used as a paper guide, but in inkjet printers, the front surface of the platen cannot be used as a guide because the platen 2 gets dirty.

提供するものである。以下、図面により実施例を詳細に
説明する。In order to solve the above-mentioned drawbacks of the conventional example, the present invention provides a paper guide on the front surface of the head section, and a roller that contacts near the top of the paper guide, so that the ink ejection position from the head section is adjusted to the paper guide. The purpose of this is to print when the leading edge of the paper reaches the printing position, so there is no margin at the leading edge of the paper, and the trailing edge of the paper is also placed close to the paper guide and main paper feed roller. You can print until the paper comes off, so
There are fewer margins, and because the paper is fed in a straight line, the paper can be set automatically without any other paper feeding mechanism.Also, since the paper does not bend, printing can be performed on a flat surface. Therefore, the present invention provides a paper feeding device for an inkjet printer that can widen the ink jetting width and can also be used in a multi-head inkjet printer. Hereinafter, embodiments will be described in detail with reference to the drawings.

紙ガイド７に押圧されている。FIG. 2 shows a configuration diagram of a paper feeding device according to an embodiment of the present invention, in which 1 is a head section, 7 is a paper guide provided in front of the head section 1, and 8 is a paper guide provided near the top of the paper guide 7. The main paper feed rollers in contact are a vertical paper feed roller 9 and a discharge roller 10 , and the main paper feed roller 8 is pressed against the paper guide 7 by a pressing mechanism 11 .

れて、紙４は紙ガイド７の直線部が長いため、曲がらな
いで上に進む。In the paper feeding device of this embodiment configured as described above, the paper 4 fed out by the vertical paper feeding roller 9 is moved to the paper guide 7.
The paper is fed straight upward along the paper guide 7 and the main paper feed row 28. The paper guide 7 uses a low-friction member, and the main paper feed roller 28 uses a high-friction coefficient member. Because it is long, it moves upward without bending.

がなくても印字ができるので、紙４の裏面に支えがない
部分で印字しても、紙４の腰の強さだけで曲がることが
なく、上へ送られ、排出ローラ１０にくわえ込まれる。Printing is performed on the paper 4 coming out of the paper guide 7 using ink jetted from the head section 1. Unlike impact printers, this inkjet printer can print without any support on the back side of the paper 4, so even if you print on a part of the back side of the paper 4 that has no support, it will bend just by the stiffness of the paper 4. The paper is sent upward without any problems, and is gripped by the discharge roller 10.

用することができる。The discharge rows 210 are in light contact with each other, rotate at a higher speed than the main paper feed roller 8, and constantly pull the paper 4 held in their mouths. Therefore, the ejection roller 210 can slide between the paper 4 and the paper 4, but if the drive roller of the ejection roller 10 is placed on the back side of the paper 4, the printed surface will not be soiled. , printing can be performed when the leading edge of the paper 4 reaches the printing position above the paper guide 7, so there is no need to create a margin at the leading edge of the paper 4, and the trailing edge of the paper 4 also
Since printing can be performed until the paper 4 comes off from the paper guide 7 and the main paper feed roller 8, the margin is small, only a few Im, and furthermore, there is no need for any other mechanism to feed the paper 4 in a straight line.
It can automatically cut the paper seven times, and since the paper 4 is not bent and printing is performed on a flat surface, the ink jetting width can be widened, and it can also be used in multi-ink jet printers.

が入れである。In FIG. 2, the paper guide 7 is fixed, the main paper feed roller 8 is pressed against the paper guide 7 by a pressing mechanism 11 and rotated by a drive belt 12, and the vertical paper feed roller 9 is rotated by the main paper feed roller. Although it rotates at the same peripheral speed as 8, a one-way clutch is engaged in the vertical paper feed roller 9 in case the paper 4 is pulled by the main paper feed roller 28.

付けるようにしている。FIG. 3 shows a configuration diagram of a paper feeding device according to another embodiment of the present invention, and parts with the same symbols as in FIG. 2 indicate the same devices, so explanations will be omitted. In the embodiment, the main paper feed row 28 is fixed, and the paper guide 7 presses the paper 4.

近づけることができ、印字位置が外乱に乱されることが
少なく、紙送り精度を上げ易いという利点がある。In the paper feeding device of this embodiment, the paper guide 7 is a thin plate,
Because of the spring properties of this plate body, it is brought into pressure contact with the main paper feed row 28, so the mechanism is simpler than the embodiment shown in FIG. 2, and the head portion 1 can be brought closer to the paper 4. This has the advantage that the printing position is less likely to be disturbed by external disturbances, and paper feeding accuracy can be easily improved.

る。As explained above, according to the present invention, since printing is performed near the top of the paper guide, it is possible to print on almost the entire surface of the paper, and it is also advantageous for automatic feeding.
It also has the advantage that it can be used in multi-head inkjet printers in which a large number of heads are arranged vertically.
