Abstract: 1,040,594. Selective printing. BELL PUNCH CO. Ltd. Aug. 19, 1963 [Aug. 20, 1962], No. 32697/63. Heading B6F. [Also in Division G4] A system for recording transactions, e.g. a cash register, offers a limited selection of its input devices for actuation, e.g. illuminates a portion of a keyboard and then after a selected input has been made offers a different limited selection which depends on the first input. As described, a plurality of relay calculator cash registers each capable of addition, subtraction and multiplication are connected to a central store. General.-Each cash register has a lamp beneath each key so that when selected lamps are lit they can be seen through the keys, so as to put questions about the transaction being made. Answers are given by a salesman who presses one or more of the illuminated keys and/or inserts one or more punched card "tokens" giving for example his number and the account number of the customer. The register then steps to put further questions regarding the articles being sold and the method of payment. If the customer's credit card (Fig. 14, not shown) giving his account number, and a price tag (Fig. 15, not shown), have already been inserted, the register passes straight through these steps so that redundant questions are avoided. The price of an article may be multiplied by the number of articles of that type, the total price for a list of articles may be calculated, and tax charges, discounts and delivery charges may be taken into account. All the information inserted is printed on a sales slip which is inserted at the start of the transaction, and a record roll may be printed and retained in the machine. Keyboard.-The keyboard includes a bank of numerical keys 10 and two banks of control keys 12, 14. The keys may be of translucent plastics so that they may be illuminated from below. Depression of one or more of the illuminated keys closes corresponding contacts so that, when an enter key is depressed, corresponding relays are energized. An error key is also provided. An alternative keyboard may have no moving parts but may operate under the capacitance or leakage current due to the salesman's finger. The printer (Figs. 42 and 45, not shown) includes a guide 3558 for the reception of an inserted sales slip and a feed roller 3562 which is indexed intermittently to feed the slip step-bystep up a curved guide 3560 when a blocking pawl 3566 is withdrawn by a solenoid which works against the action of a spring 3570. The roller 3562 is indexed by a solenoid 3524 which is repeatedly energized thus repeatedly attracting its armature 3580 which co-operates with a non-return pawl 3582 to index a gear 3578 through a corresponding number of steps. Type wheels 3592 are similarly indexed to their desired positions. Between each advance of the slip, selected ones of a row of print hammers are operated to press the slip against an inked ribbon 3590. Each hammer is actuated by a corresponding slide bar 3608 which is moved rearwardly by a corresponding solenoid 3830. Duplicate copies may be produced or a record roll may be provided.
