Printer for Large Characters

In the airline industry, there is a need to print large characters. For example, it is useful if baggage checks are printed in large characters to aid in baggage handling. The drawing shows a simple and low-cost printer which can be used to print large characters.

Mounted over paper 1 moving in direction of arrow 2 is a linear array 3 of pens 4. Each pen 4 is mounted on an arm 5 pivotable about shaft 6 so as to be independently movable into and out of contact with paper 1, by selectively operating electric or fluid controls 7. In the example shown, the printer has just synthesized the characters PA.

Pens 4 can be of any convenient type such as felt-tip, fiber-tip, or ball-point pens, or can even be wheels or brushes. The character size and legibility are dependent on the number of pens 4 and their spacing across paper 1. Since the pen diameters will invariably be greater than the line pitch, the pens are staggered in the direction of movement of the paper. As an alternative and instead of using a linear array 3 of pens, some other array such as a circular array could be used.

If desired the pens 4 can be arranged to provide no gaps between the lines they draw. However, by using discrete lines to synthesize the characters, laser scanning for machine reading purposes becomes more feasible.
