Patent GB-569411-A (GB)
Abstract: 569,411. Cash registers. KOOPERATIVA FORBUNDET FORENING U.P.A. Sept. 30, 1942, No. 13703. Convention date, Sept. 30, 1941. [Class 106 (i)] A cash register comprises means for feeding, printing and cutting off a check slip, these means comprising printing rollers and a printing ribbon rendered effective by a plurality of hammers rising from beneath them, and also means whereby a bill may be inserted above the check slip and under the printing ribbon, and printed ; characterised by additional means which throw out of gear the feeding and cutting mechanisms for the check slips and cause a first impression on the inserted bill by all the hammers and a second impression by only some of the hammers. In normal voucher-issuing operations, the key 37 is in its outward inoperative position, and when a crank 67 is turned, the check-slip a is fed by a feed roller 5 and an upper roller 6 in known manner. When a roller 30 drops off a highpoint 33 of a cam 35, striking pins 36 of a spring-pressed member 29 actuate hammers 25, 26, 27, 28 which by their own momentum press the check-slip and the ink ribbon 72 against the type-wheels. A pin 53 on a gear 52 then rocks a member 51 to cause a lever 45 to contact a pin 55 on the hammer lever 28, while a portion 50 contacts the underside of the hammer levers 25, 26, 27 so that in the succeeding half-cycle, when the roller 30 drops off a second high point 34, the hammer levers are out of range of the pins 36 and printing does not take place. After further feeding of the check-slip, a cam 19 lifts an arm 13 to actuate a blade 8 which severs the voucher. Printing on, inserted material.-For printing bills, the key 37 is pressed inwards. A pin 39 on the key stem rocks a lever 42 to swing the lever 45 out of line with the pin 55. At the same time, an arm 56 displaces links 57, 58 to rock a lever 11 out of alignment with the arm 13 so as to disable the cutting mechanism. A pin 59 on the lever 11 displaces a plate 61 so as to move the roller 6 laterallv from the check slip and so to disable the check feed. The pin 59 also rocks a lever 65 which uncovers an opening 3 in the side of the casing to allow the insertion of a bill b from a guide plate 69 between the check slip a and the ink ribbon 72. In the manner previously described, printing takes place at the first half-cycle, and the bill which projects laterally of the check slip is fed by the laterally displaced feed roller 6 and lower roller 5. When the pin 53 actuates the arm 49, hammers 25, 26, 27 are rendered inoperative as before, but as the lever 45 does not contact the pin 55, the hammer 28 is 'operated to repeat the amount. Specification 438,574 is referred to.
