Abstract
A printer having a print ribbon feed mechanism is disclosed which allows optimal feeding of a print ribbon, eliminating unnecessary consumption of the ribbon. The mechanism includes first and second clamp means mounted on a stationary section and a print carrier of the machine, respectively, which are both controlled in accordance with movement of a print head from and to a print enabling position. Means are provided which are connected to a carrier indexing mechanism for impositively driving print ribbon supply and takeup spools disposed on the stationary section to wind a print ribbon onto them during a carrier return operation whereas they allow the ribbon to be unwound from the ribbon spools when the carrier advances.
