<p>PURPOSE:To prevent a recording paper from being contaminated immediately after the start of recording, without reducing a driving force of a recording head, by a method wherein energization of a driving member is stopped at least one time before a recording head is moved from a non-printing position to a printing position, and thereafter energization is restarted. CONSTITUTION:When a solenoid is energized at a recording-starting time T0, the recording head is started moving to the printing position. When the energization of the solenoid is stopped at time T1, the head is moved toward the printing position under inertia, but it is gradually decelerated to be stopped by a restoring force of the spring. When the solenoid is again energized at time T3, the head is again moved under acceleration toward the printing position, and reaches the printing position at time T4. Since the period of time T4-T3 is short, the velocity of the head at the time of reaching the printing position is low, so that an impact force is small, and the recording paper is not contaminated. Thereafter, energization of the solenoid is continued to time T5, thereby printing, and when the energization is stopped, the head is returned to the non-printing position by the restoring force of the spring.</p> |
