Abstract

PURPOSE:To prevent the unnecessary increase and decrease in the tension of a ribbon accompanying the irregular rotation of a supply reel, by providing a supply reel driving belt cooperated with a ribbon feed roller. CONSTITUTION:A ribbon 8 passes between a ribbon feed roller 3 and a pinch roller 7 from a supply reel 1 through a ribbon guide 5 and a printing head 6 to reach a take-up reel 2. A supply reel driving belt rotates with the rotation of the ribbon feed roller 3 to drive the ribbon wound over the supply reel 1. the ribbon 8 moves at a constant speed during by the rotation of the ribbon feed roller 3 but, at this time, the supply reel driving belt 4 also rotates at the same speed or at a linear speed slightly slower than said speed. Since the supply reel is driven by the supply reel driving belt, no excessive tension is applied to the ribbon and, since the supply reel is not rotated excessively by inertia when the feed of the ribbon is stopped, the ribbon is not slackened.

Description

【発明の詳細な説明】 ＆　発明の詳細な説明 〔産業上の利用分野〕 本発明はリボン送り機構に関し、特に通電転写式シリア
ルプリンタに用いらｎるリボン送り機構に関する。DETAILED DESCRIPTION OF THE INVENTION & DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a ribbon feeding mechanism, and more particularly to a ribbon feeding mechanism used in an electrical transfer type serial printer.

〔従来の技術〕[Conventional technology]

従来、この種のリボン送り機構は供給リール駆動ベルト
を有していなかった。Previously, this type of ribbon feeding mechanism did not have a supply reel drive belt.

〔発明が解決しようとする問題点〕[Problem that the invention seeks to solve]

上述した従来のリボン送り機構は、供給リール駆動ベル
トがないので、供給リール回転が不規則になりやすく、
送り出したリボンの張力を一定に′保つのがむずかしい
という欠点があった。The conventional ribbon feeding mechanism described above does not have a supply reel drive belt, so the supply reel rotation tends to be irregular.
The drawback was that it was difficult to maintain a constant tension in the ribbon as it was fed out.

〔問題点を解決するための手段〕[Means for solving problems]

本発明のリボン送り機構は、リボン送りローラと、リボ
ン供給リールに接し、リボン送りローラに連動して動く
供給リール駆動ベルトとを有している。The ribbon feed mechanism of the present invention includes a ribbon feed roller and a supply reel drive belt that is in contact with the ribbon supply reel and moves in conjunction with the ribbon feed roller.

Eight pieces of ribbon flow from the supply reel l, through the ribbon guide 5, the print head 6, between the ribbon feed row 23 and the pinch roller 7, and reach the take-up reel 2. The supply reel and drive belt rotate with the rotation of the ribbon feed roller 3, and drive the ribbon wound around the supply reel.

rotate at the same speed or at a slightly slower linear speed.

供給リールは、この供給リール駆動ベルトによって駆動
されるため、リボンには余分なテンシ璽ンがかからなく

分に回転する事がないため、リボンがたるむ事がない。The supply reel is driven by this supply reel drive belt, so no extra tension is applied to the ribbon, and when the ribbon feed is stopped, the supply reel does not rotate excessively due to inertia, so the ribbon becomes slack. There's nothing wrong.

〔発明の効果〕〔Effect of the invention〕
