Abstract
930,835. Typewriters &c. KOOPERATIVA FORBUNDET. Dec. 8, 1959 [Dec. 8, 1958], No. 41773/59. Class 100 (4). A printing mechanism for a computing or accounting machine or for a cash register comprises type bars 2 directly fixed to actuators 1 of the machines which are set by sliding horizontally under the action of a magnet 5. A paper record strip 16 is fed through slots 14, 15 of a transparent guide 12 round the inside of which it is fed by an arm 18. To effect impression a bar-shaped platen 11 and pins 7 are moved together by an electromagnet 9 which acts on some or all the pins 7 simultaneously. After impression the arm 18 feeds the strip 16 until the printing can be viewed through the guide 12. The type bar portion 2 may be provided with a toothed bar 20 on its underside so that the pins 7, which are correspondingly shaped, align the bar for impression. The types 4, Fig. 3, are mounted on two sides of an angle-iron 2 which is pivotally mounted by end-pieces 3 on the actuator 1 so that either type set may be rotated to the operative position to change from printing positive amounts to printing negative balances. Specification 912,140 is referred to.
