【発明の詳細な説明】
本発明は、記鎌紙に印字するプリンタの紙送り機構に関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper feeding mechanism for a printer that prints on paper.
配縁紙に印字するプリンタの紙送りは１、ドツトプリン
タを、例にとると、第１図の印字パターンのωに示す如
く、一般の帳票や文章では、１／６インチの紙送り量が
標準である。ｆＯに示す如く、拡大文字や、グーラフイ
ック等の紙送りは、任意の紙送り量が必要とされる。For printers that print on border paper, the paper feed is 1, and for dot printers, for example, as shown by ω in the printing pattern in Figure 1, the standard paper feed is 1/6 inch for general forms and documents. It is. As shown in fO, an arbitrary paper feed amount is required for paper feeding for enlarged characters, goura flicks, and the like.
φ、ｆＯの例の様な各種の印字パターンを構成し、印字

ができるパルスモータを用いた紙送り機構が使用されて
いる。しかしパルスモータとその駆動回路は高価なため
、桁数が８０桁以上の＾級なプリンタや、特殊なへ用造
のみしか使用することができなかった。Conventionally, a paper feeding mechanism using a pulse motor whose pitch can be freely changed has been used as a paper feeding mechanism for forming and printing various printing patterns such as φ and fO. However, because pulse motors and their drive circuits are expensive, they could only be used in high-class printers with 80 or more digits or for special applications.
４０桁以下の小型で安価なプリンタの紙送り機構は、紙

てしまう。例えば１７６イ／テ送りのものが多く、標準
とされており、拡大文字や、グラフィック印字等任意や
紙送りができない欠点があった。The paper feed mechanism of small and inexpensive printers of 40 digits or less often uses a paper feed pawl to drive a paper feed pawl that is directly connected to a paper feed roller, and the paper feed amount is determined by the number of divisions of the paper feed pawl. It's decided. For example, 176 i/te feed is often used as the standard, but it has the drawback that it cannot print enlarged characters, graphics, etc., or paper feed.
本発明は、かかる欠点を除去したもので、その目的は、
任意の量の紙送りができ、安値で制御方ｌ＆が容易な紙
送り機構を提供するものである。The present invention eliminates such drawbacks, and its purpose is to:
To provide a paper feeding mechanism that can feed paper by any amount, is inexpensive, and is easy to control.
以下、本発明の一実施例を第２図、第５図、第４図、第
５図を使用して詳しく説明する。Hereinafter, one embodiment of the present invention will be described in detail using FIGS. 2, 5, 4, and 5.
９２図は紙送り機構の待機図、第５図は紙送り時の作動
図、第４図は任意の紙送り時の作動図である。FIG. 92 is a standby diagram of the paper feeding mechanism, FIG. 5 is an operation diagram when paper is being fed, and FIG. 4 is an operation diagram when an arbitrary paper is being fed.
定速回転しているカム１は、Ｒ１，Ｒ２，Ｒ５と５組の
リードを持ち、各々のリードに対応して、Ｔ１〜Ｔ５の
位置信号を出す位置信号装置２を同軸上に設けている。A cam 1 rotating at a constant speed has five sets of leads R1, R2, and R5, and a position signal device 2 that outputs position signals T1 to T5 is provided on the same axis corresponding to each lead. .
（位置信号装置の詳細は省略する。）

を規制する保合部５ｂ−５ｄを設けている。(Details of the position signal device will be omitted.) The paper feed lever S is provided with a paper feed claw 5 that engages with a paper feed spring 4 for paper feeding and rotates a paper feed claw 9. Further, the distal end portion is provided with retaining portions 5b to 5d that engage with the trigger lever 6 and regulate the rotation angle.

Ｈ間ｔができる様な配置、組立がされている。The trigger lever 6 is activated by energizing the trigger electromagnet 80.
It is sent to the trigger spring 7 and rotated in the direction of the arrow Byj. In order to facilitate rotation, the paper feed lever 5 is in contact with the engaging portion 5b of the trigger lever 62 at the position of the maximum lead R1 of the cam 1 at the portion 5a.
They are arranged and assembled in such a way that there is a distance between H and t.

rotates in the direction of arrow B, and is disengaged from the paper feed lever 5. The paper feed lever 5 follows the lead of the cam 1 by the tension of the paper feed lever spring 4, moves in the direction of arrow C (B), rotates the paper feed pawl 9 with the paper feed pawl 5, and rotates the paper feed pawl wheel 9. The paper feed row 210 on the same axis also rotates, and the paper 11

。The 5th E is a time chart with 0 energization and is an operation diagram performed, in which the paper feed lever 5 does not engage with the 50 part of the paper feed lever because the trigger lever 6 has been operated up to T5.
The cam slider rotates at R5fi and stops at 5d. Accordingly, the teeth of the paper feed ratchet 9 can feed two teeth 9a to 9c, resulting in a standard paper feed amount of 176 inches (for example).

る。Fig. 4 is a time chart of the energization. The difference from the 00 case described above is that the energization is from T1 to T2, which is shorter than 0, so the trigger lever 6 is 501il of the paper feed lever. engage. This is to regulate the rotation angle of the paper feed lever S, and moves the teeth of the paper feed ratchet from 9a to 9b.
You will have to send one tooth up to that point. This is half of the amount of paper feed compared to the case of a double-stroke, and can feed paper by, for example, 1/12 inch.

できる。In this way, the paper feed operation is performed, but in the above embodiment, the paper feed lever is engaged at five points s, and the paper feed ratchet wheel's feed *a is 1 to 2, but the number of engagement points is increased. It is also possible to provide four or more cams and increase the lead of the cam 1 accordingly to feed paper by an arbitrary amount. Further, as shown in FIG.
The paper feed amount can be changed even if a plurality of new ones are provided as shown in FIG.

するものである。As described above, the present invention provides a plurality of retaining portions on a part of the paper feed lever or the trigger lever, and changes the energization time of the p-electromagnet in accordance with the position signal of the cam. Therefore, it is possible to easily feed a desired amount of paper, and compared to the conventional one using a pulse motor, the paper feeding mechanism, including the drive circuit, is cheaper and easier to control. Various printing patterns are now possible even in a small 40-digit printer, achieving the initial objective.
