Abstract

PURPOSE:To prevent previously printing inferiority such as a printing blur or the like from occurring by a method wherein a joint of an ink ribbon is detected, and printing near the joint is avoided. CONSTITUTION:A magnetized part 2 is provided near a joint 1b of an ink ribbon 1a. The magnetized part 2 is annexed to an end of the ink ribbon on a before stage of the ink ribbon before and after the joint. In the case where the magnetized part 2 of the ink ribbon 1a is detected by a magnetism detecting part 3, a control part 6 interrupts temporarily printing and besides, operates a ribbon feed mechanism 5. A constant distance of the ink ribbon 1a is sent by rotating a reel in a cassette 1, and the joint 1b of the ink ribbon 1a is forcibly made to pass a printing head part of an impact type printer, and an ink face other than the joint 1b of the ink ribbon 1a is made to face a front of the printing head. Printing at the joint 1b of the ink ribbon 1a is avoided thereby.

リボンの継なぎ目を検出する機構は装備していない。Conventionally, impact printers perform printing using ink ribbons with seams, but are not equipped with a mechanism for detecting the seams of the ink ribbon.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

上述した従来のプリンタではインクリボンの継なぎ目を
検出できないため、継なぎ目で印字してしまい印字かす
れなどの印字不良が発生するという欠点がある。The above-mentioned conventional printer cannot detect the seam of the ink ribbon, so it has the disadvantage that it prints at the seam, resulting in printing defects such as blurred print.

本発明の目的はインクリボンの継なぎ目での印字を回避
するインクリボンの継なぎ目検出機構を提供することに
ある。An object of the present invention is to provide an ink ribbon seam detection mechanism that avoids printing at the seam of the ink ribbon.

るものである。In order to achieve the above object, the ink ribbon seam detection mechanism according to the present invention includes an ink ribbon provided with a magnetized portion near the splice, a magnetic detection portion that detects the magnetized portion, and a magnetic detection portion that detects the magnetic portion. The printer has a control section that is activated by a detection signal from the control section to temporarily interrupt printing, and a ribbon feeding mechanism that is activated by a signal from the control section and feeds the ink ribbon.

付設しである。In FIG. 1, the ribbon cassette used in the present invention has a structure in which a reel (not shown) is housed inside a cassette case 1, an ink ribbon 1a is fed out from one reel, and a used ink ribbon 1a is wound onto the other reel. It is. This ink ribbon 1a is, for example, a plurality of ink ribbons of different colors successively spliced together in the length direction. Therefore, in the present invention, a magnetized portion 2 is provided near the seam 1b of the ink ribbon 1a. The magnetized portion 2 is attached to the end of the ink ribbon on the front stage of the spliced front and rear ink ribbons.

る。In the embodiment, when the magnetized part 2 of the ink ribbon 1a is detected by the magnetic detection part 3, the control part 4 temporarily interrupts printing, operates the ribbon feeder 5, and removes the magnetic part from the inside of the cassette case 1 (not shown). The ink ribbon 1a is fed by a certain amount by rotating the reel, and the seam 1b of the ink ribbon 1a is forced to pass through the print head portion of the impact printer, thereby removing ink from areas other than the seam 1b of the ink ribbon 1a. Printing at the seam 1b of the ink ribbon 1a is avoided by facing the front surface of the print head.
