摘要： A line printer apparatus with which a printing control operation is carried out by using a printing mechanism and printing operation control unit in which the reversal of the motion of a printing unit is carried out in synchronization with the feeding of a paper to be printed. The apparatus includes a decision unit for deciding whether or not a shuttle carrying the printing unit should be stopped during the reversal of the motion in accordance with printing information supplied to a unit for controlling the driving of the shuttle and the condition of feeding of the paper; reversing motion stopping means for stopping the reversing motion of the printing unit and holding it in the stopped state by supplying reversing stopping information to the printing operation control means when the paper feeding time of the paper to be printed is greater than the time of the reversing motion of the printing unit; and releasing means for releasing the stopping of the reversing motion of the printing unit in relation to the timing of termination of paper feeding of the paper to be printed and restarting the printing from a printing starting position. Therefore, the printing operation is restarted immediately after the termination of a paper feeding operation even when the time of the paper feeding is longer than the time of reversing motion of the printing unit.

摘要： A printing apparatus includes an advancing circuit, such as a tractor, disposed on a first side of a printing head for feeding recording material. The printing apparatus has an improved tension circuit for providing adequate tension to the recording material in order to eliminate slack in the recording material, particularly during a manual feeding operation. Tension is provided by a motor driven driving roller which is disposed on a second side of the printing head opposite the first side. The driving roller is rotated in a direction in which tension is to be provided to the printing material by a tension motor. A rotary encoder, for example, is fixed to a rotating portion of the motor for driving a tractor which advances the recording material. The rotary encoder outputs position pulse signals indicating the displacement of the advancement elements. The tension motor is driven in response to the position pulse signals by a position feedback control operation performed by a control circuit. The tension circuit can also be employed in a printing apparatus which automatically advances recording material, thereby attaining the advantages set forth above.
