ABSTRACT:
The marking device has a housing supporting a marking head for movement longitudinally and laterally preselected amounts controlled by a pair of stepper motors. The marking head has a plurality of marking pins that are air actuated and controlled by appropriate solenoids. The marking device is arranged to move the head longitudinally in a raster pattern so that each of the pins is actuated to form a portion of a character upon longitudinal movement through a selected distance. The marking head is then moved to a parallel y axis and subsequently moved longitudinally in a reverse direction. During the movement in a reverse direction, all of the pins are actuated to form other portions of the characters in the array. With this arrangement, a plurality of characters are simultaneously formed by impressing dots on an object until the marking head moves forward and backward on different y axes to simultaneously form all of the characters in the array. Another embodiment discloses a marking head having pairs of longitudinal lines of pins which are arranged to form characters with a double line.
