Latest Patents

One of Harasina's most remarkable inventions is the flying printer. This device features a continuously-rotating ratchet wheel that drives a printing hammer through an interposed trigger lever. The print drum rotates continuously at a speed fixed in relation to the ratchet wheel. The design ensures that the striking face of a tooth on the ratchet wheel lies in the same plane as the stroke-receiving face of the trigger lever. This configuration enhances the efficiency of energy transfer from the ratchet wheel to the printing hammer. Additionally, the printer includes a paper-feed mechanism that operates intermittently while the drum rotates continuously. A ribbon-transfer mechanism is also integrated, allowing for the utilization of the entire ribbon and reducing the force needed to reverse the direction of transfer. This innovation results in a lighter driving mechanism, contributing to the overall compactness of the printer.
