Abstract: An electronic cash register includes a printer system for printing out a transaction data on a receipt bill or a journal paper. A print preset system is provided for selectively printing out the transaction data. A print inhibition preset key develops a print inhibition command which is stored at the last bit of a memory address of the corresponding transaction data. In a normal registration operation mode, a signal detection circuit functions to detect the print inhibition command stored in the last bit. When the print inhibition command is detected, the signal detection circuit functions to preclude the transaction data stored in the corresponding memory address from being transferred to the printer system.

Abstract: A read operation control system is included in an electronic cash register for checking purposes. The actual read operation is not conducted until the operator introduces numeral data indicating the cash amount contained in a drawer case of the electronic cash register. The thus introduced numeral data is compared with accumulated data stored in a memory section of the electronic cash register, the accumulated data representing the total cash amount registered into the electronic cash register. The difference between the introduced numeral data and the accumulated data is calculated, and the calculation result is printed out onto a check list.

Abstract: A numbering machine includes a digital data control system for varying the print data. A keyboard panel is provided for introducing a desired initial number from which the numbering operation should begin. A desired skip number is introduced through the keyboard panel to set the numerical gap between successively printed numbers so as to perform the numbering operation, for example, 2, 4, 6, 8, 10, . . . . The digital data control system can also perform a subtraction operation. Further, the number of times of the same data is printed may be preset to perform the numbering operation, for example, 1, 1, 1, 2, 2, 2, 3, 3, 3, . . . . These functions can be combined to perform a wide variety of numbering functions and sequences.

Abstract: An electronic cash register comprises a control switch for allowing and prohibiting printing and issuance of a receipt according to input data introduced by input keys and a delay circuit for deferring operation of the control switch for a predetermined period of time of the actuation of the control switch. The delay circuit provides accurate control for the allowance and prohibition of receipt printing and issuing operation independently of actuation timings when the control switch is energized, thereby preventing random printing and publication of the receipt dependently on the timed relationship of actuation of the control switch.

Abstract: A postage meter is provided with a combination whereby the detent members retarding the selector gears of the postage meter are removed immediately prior to the changing of the postage amount. The combination is also able to engage a bail lock-out mechanism at the same instant the detent is removed to prevent accidental meter trips or tampering with the meter.

Abstract: An electronic cash register comprises a keyboard having a plurality of numeral entry keys and function keys, a drawer to be opened after the depression of a specified function key, a printer for printing on a blank receipt the data defined by operation of the entry keys and function keys, and a receipt feed device for feeding a blank receipt and taking out a printed receipt. The electronic cash register is further provided with a detection device and a receipt cutting device. The detection device detects the drawer-shutting and thus actuates the receipt cutting device when the drawer is shut.

Abstract: A device for transmitting information in the form of an electrical signal to at least one mechanism for giving a readout of the information, comprises a readout mechanism which has at least one symbol wheel which carries symbols on its circumference. A plurality of angularly spaced and radially extending actuating members are affixed to a drive shaft which rotates to move the actuating members in a first plane. The actuating members are divertible into a second plane parallel to the first plane by a switch arranged in the plane of movement of the actuators so as to selectively divert the actuating members into a second plane. The actuating members have individual symbols corresponding to the number of readout symbols and guide walls are provided for supporting the actuators and the switch, as well as a gear drive for a symbol wheel in the respective first and second planes. A relay is employed for sensing the symbol position of the symbol wheel and it is connected to the switch to energize the switch.
