Horizontal Cup Printer

This serial printer (Fig. 1) includes a printing element 10 which is in the shape of a cup. The print element 10 is moved traversely on a carrier by lead screw 4. The print element 10 has a plurality of fingers. For convenience of illustration, only fingers 10A, 10B and 10C are shown. Each of the fingers on print element 10 has two characters thereon. For example, finger 10A has characters 10A1 and 10A2.

Print element 10 is rotated by motor 20 which may be either a stepping motor or a servo motor. In order to place a selected finger in print position, motor 6, which may be a stepping motor or DC servo motor, operating through lead screw 4 and nut 13, moves the cup horizontally to the proper print position. The horizontal movement also selects either the first or second row of characters on the print element 10. Two print hammers 11 and 12 are positioned to strike the first and second rows of characters, respectively, on the print element. When the cup is positioned, the appropriate hammer is activated. Instead of utilizing two hammers as shown, a single moveable hammer could also be utilized.

Fig. 2 shows an enlargement of one of the fingers on print element 10. The second row of characters on each print element is partially surrounded by a cut- away portion 30, such that when the character in the second row is struck it does not produce shadow printing by the first character.
