Abstract

PURPOSE:To prevent the falling of the powder of correction ink, by providing a support member having a surface almost the same to the guide surface of a guide part for guiding an ink ribbon and supporting said guide part. CONSTITUTION:The diameter at the part receiving a correction ribbon of a pulley 8 is made the same to the diameter of the receiving part of a pulley receiver 10 and the flange parts 8a, 8b provided to the upper and lower ends of the pulley are supported by the outside of the pulley receiver 10 to suppress the shaking of the pulley 8. By this method, the gap between the pulley 8 and the pulley receiver 10 is perfectly eliminated and, even if the offset of a tape is generated in the residual amount of the tape, the correction ribbon is not involved. A cassette 9 is arranged to the cassette frame on a carriage 4 and supplies an ink ribbon between a daisy wheel 6 and printing paper and winds up the same. When the correction ribbon 7 is supplied toward the hammer 5 through the pulley 8, the end part of the tape is prevented from being involved in the pulley 8 and the correction ribbon 7 is closely contacted with the pulley 8 and no strain is generated.

。In particular, as typewriters have become smaller, their printer units have become smaller, and in printers with carriages, a technique has been developed to place the correction tape vertically, that is, to attach the correction tape perpendicular to the direction of carriage movement. Ta.

みが生じて。However, if the axis of the pulley that guides the correction ribbon is fixed, the approach angle of the correction tape to the pulley will change depending on the amount of correction tape remaining, and the gap created between the pulley and the pulley receiver may cause the tape to fall. There is. At this time, if the tape tension is large, distortion will occur in the correction tape.

カバーアップタイプの修正テープの場合、修正インクの
粉が落るという欠点を有していた。Cover-up type correction tape has the disadvantage that correction ink powder falls off.

［目的］ 本発明は」二連の点を鑑みて、改良したプリンタを提供

れる印字紙にインクリボンを介して所望の印字をする。In the figure, 3 is a platen around which printing paper is wound. Reference numeral 4 denotes a carriage, which is moved on an axis arranged parallel to the platen 3 by a driving means (not shown). A hammer 5 is placed on the carriage 4 and impacts the Digiwheel by being driven electromagnetically. A digiwheel 6 having type characters is rotatably arranged on a carriage and is pressed by a hammer 5 to print desired characters on the printing paper wound around the platen 3 via an ink ribbon.

との間にインクリボン供給し、また＠き取る。As shown in FIG. 3A, the pulley 8 is received in a bobbin receiver lO having a hole 10a for receiving the bobbin shaft. Make the diameter of the part of the boo 98 that receives the correction ribbon the same as the diameter of the part of the pulley receiver 10 that receives the correction ribbon, and support the flanges 8a and 8b at the lower end of the pulley on the outside of the pulley receiver to suppress backlash of the pulley. I did it like that. By doing this, there is no gap between the pulley 8 and the pulley receiver 10, and the situation shown in FIG. The ribbon will not get caught. A cassette 9 is arranged on a cassette frame on a carriage, and supplies an ink ribbon between the Digiwheel 6 and printing paper, and also takes it away.
