Abstract:
A line thermal head letter printing method for printing letters on a print object sheet by using a line thermal head and a hot release type thermal transfer ribbon tape, comprising the steps of:providing a friction transmission including first transmission of power via a first one-way clutch gear configured to transmit a rotation of a stepping motor via a first transmission roller and second transmission of power via a second one-way clutch gear configured to be rotated by said first transmission roller via a second transmission roller;feeding a necessary amount of said ribbon tape at a velocity synchronized with a transfer velocity of said print object sheet by using said stepping motor; andwinding said ribbon tape via said friction transmission by a power rotating in one direction at a velocity higher than said transfer velocity of said print object sheet being transferred, said first one-way clutch gear transmitting a rotation of said stepping motor via said first transmission roller and said second one-way clutch gear being rotated by said first transmission roller via said second transmission roller for said winding.
