AI Technical Summary

⚠Technical Problem

The risk of ribbon shortage in existing printers can cause printers to malfunction, affecting print quality and efficiency.

⚗Method used

A single drive unit simultaneously drives the ribbon feed roll and the take-up roll. Through a one-way clutch and transmission gear structure, the ribbon feed roll and the take-up roll rotate actively and passively when paper is being fed or unloaded, thus maintaining consistent speeds.

🎯Benefits of technology

This effectively avoids the problem of ribbon shortages, ensures the printer works normally, and improves print quality and efficiency.

Abstract

The application belongs to the technical field of printing equipment, and particularly relates to a carbon tape conveying device and a printer. The carbon tape conveying device comprises a carbon tape, a driving member, a carbon tape feeding reel assembly and a carbon tape recycling reel assembly. The driving member has a rotatable output part, and the output part rotates around a first direction or a reverse direction of the first direction. The carbon tape feeding reel assembly is in transmission connection with the output part of the driving member. The carbon tape recycling reel assembly is in transmission connection with the output part of the driving member, and the carbon tape is arranged around the carbon tape feeding reel assembly and the carbon tape recycling reel assembly. Under the condition that the output part rotates around the first direction, the driving member drives the carbon tape recycling reel to rotate actively, and the carbon tape recycling reel drives the carbon tape feeding reel to rotate passively through the carbon tape. Under the condition that the output part rotates around the reverse direction of the first direction, the driving member drives the carbon tape feeding reel to rotate actively, and the carbon tape feeding reel drives the carbon tape recycling reel to rotate passively through the carbon tape. The application can improve the situation of carbon tape being pulled and broken, so that the printer can work normally.
