してエンドレスとしている。 The print band is formed by, for example, embossing letters at the same pitch on the outer periphery of a metal strip-like thin plate by means such as etching, and the ends of the band are joined by welding means such as electron beam or laser beam to form an endless band.

損する等の重大な事故を起こすことがあつた。 The joint portion is located at the center between adjacent printed characters, and the adjacent printed characters are selected to have narrow character widths, such as "(" or ")". However, depending on the type of characters accommodated on the print band, it may not be possible to make the characters adjacent to the joint part narrower. In this case, if a joining part is provided at the center between the printed characters, the area where the strength is reduced due to the joining will be in the printed characters with a wide character width. As a result, the strength-decreased region is struck during printing, resulting in serious accidents such as the print band breaking at or near the joint.
本発明の目的は、上記した従来技術の欠点をな
くし、接合による強度低下領域が印字時に打撃さ

折損しないようにすることである。 An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art, to prevent the area where the strength is reduced due to bonding from being hit during printing, and to prevent the bonded portion or its vicinity from breaking.

明を説明する。 In the present invention, the joint portion is provided between the narrow character width type and the wide character width type, on the side of the narrow character width, so that the region of reduced strength due to the joint does not extend to the type on both sides of the joint. It is characterized by the following. The present invention will be explained below with reference to the drawings.

字２１及び２２の文字幅により決定され、このず
らし量δは次式で表わすことができる。 A print band 1 made of a metal strip-like thin plate has typefaces 2 and typemarks 3 formed integrally by etching or the like and embossed at the same pitch. The both-end joint portions 4 are provided between a wide type character 21 (M in the figure) and a narrow character type (period in the figure), and are shifted toward the narrow type type 22 side. There is. As shown in FIG. 2, the amount of offset δ between the type characters 21 and 22 from the center is determined by the character widths of the type characters 21 and 22 on both sides of the joint, and this amount of offset δ can be expressed by the following equation.
（Ｗ１／２＋Ｗ／２＋Ａ）−Ｐ／２＜δ＜Ｐ／２−（
Ｗ２／２＋Ｗ／２＋Ａ）
ここで、W1は文字幅の広い活字２１の文字

た。Ｐは各活字２間のピツチである。 (W 1 /2+W/2+A)-P/2<δ<P/2-(
W 2 /2 + W / 2 + A) Here, W 1 is the character width of the wide type 21, W 2 is the character width of the narrow type 22, w is the width of the joint 4, and A is the strength reduction due to joining. According to the experimental results, the length of the region was approximately 0.4 mm. P is the pitch between each type 2.

で、強度低下領域Ａが両側の活字２１，２２にか
かることはまずなくなる。従つて、強度低下領域
Ａが打撃されることがないので、接合部４または
その近傍で折損することはない。 Since the print band 1 of the present invention is joined by being shifted toward the narrower type 22 by the amount of shift δ, the reduced strength region A will hardly cover the type 21, 22 on both sides. Therefore, since the reduced strength region A is not hit, there is no chance of breakage at or near the joint 4.

させることはできない。 In addition, in FIG. 2, the joint part 4 is
2, since the printed characters 2 are formed with the same pitch as described above, the strength reduction area A will extend over or close to the wide printed characters 21, There is a risk of breakage due to direct impact or being affected during impact. In other words, it is not possible to join the letters at the center of the pitch between them.

る。 As described above, according to the present invention, it is possible to prevent the region of reduced strength due to joining from covering the printed characters on both sides, and the region of reduced strength is not hit during printing, thereby eliminating the possibility of breakage at the joint. , you can get a long-life printed band.
