Abstract

920,162. Selective printing. NATIONAL CASH REGISTER CO. Nov. 22, 1961 [Jan. 10, 1961], No. 41762/61. Drawings to Specification. Class 100 (4). [Also in Group XL (c)] In a high-speed printer the current in the hammer-actuating solenoid is limited by a transistor circuit (see Group XL (c)) to a value not substantially greater than is required to saturate the associated electromagnet. The printer may be of the type comprising an array of type wheels rotating at 1,200 r.p.m. above the paper. Each character is printed by movement of a hammer in the form of a thin rod under the control of the transistor circuit. The printing time may be 50 Ás.; the paper being moved in steps at 20 lines per second.
