A purpose of this invention is to totalize, store, and check special sales information concerning special customers or special purchasers, etc. Sales information of registered merchandise is totalized and stored in an area corresponding to a department code of a department file table specified in a product department, by an ordinary registration mode. When special registration process is specified by depressing a department shift key, a value of the product department is changed to a value specified in a department shift table by a special registration mode and the sales information is totalized and stored in an area corresponding to the department code of the department file table specified by the thus changed value. Accordingly, the special sales information can be totalized as ordinary sales information, and can be stored separately from the ordinary sales information.

In the present invention, data input/output equipment is connected in communication with a host machine which provides a plurality of service application programs by designating system parameters of one or more common programs. A mode setting feature designates at least a program setting mode and an execution mode. A program RAM stores at least one common program being loaded from the host machine. A parameter setting feature designates parameters included in the common program loaded in the program setting mode to define a plurality of application programs, each of which is available for a specified service. A parameter RAM memorizes the designated parameters. An entry data RAM memorizes entry data, and a service selecting feature designates one of the application programs in the execution mode.

Data I/O terminal equipment having mode setting functions for

Disclosed is an electronic cash register comprising an input unit including numeric keys to enter the numerical information such as price and function keys to enter a variety of transaction information, an internal processing circuit to process the numerical information entered by the input unit, an output unit to deliver numerical information entered by the input unit or numerical information processed by the internal processing circuit, a first memory to store the cumulative total values of the numerical information occurring from various transactions, a drawer to keep and store the cash, which is opened by an open command signal sent from the internal processing circuit at the end of various transactions, a timer to start timing in response to the open command signal of the drawer and to stop the timing action in relation to the closing action of the drawer, and a second memory to store a time information corresponding to the measured period by the timer according to the timing action of the timer.

A data input/output terminal includes a central processing unit, a random access memory (RAM), a display unit, and various data entry devices for inputting and outputting data to a host processor. The terminal includes the capability of setting program execution parameters which are necessary for the proper execution of various programs, and stores check sum codes of the parameters into an area of the RAM. Upon initial turn-on of power, the terminal determines the correct storage of the parameters in the RAM by re-calculating the check sum codes and comparing the re-calculated codes with the codes previously stored in the memory. The terminal also determines whether the RAM contains additional data storage capacity and indicates whether the RAM is capable of storing additional data or whether the RAM is full.

Data terminal with capability of checking memory storage capacity as

An electronic cash register includes an automatic registration instruction key for instructing an automatic registration operation wherein registration operation related to plural commodities is automatically conducted by the single actuation of the automatic registration instruction key. A preset system is provided for presetting desired operation sequence into a memory system. The automatic registration operation is conducted in accordance with the operation sequences stored in the memory system.

An electronic cash register includes a PLU instruction key for conducting the PLU (price look-up) function, and department keys for introducing the department information. A memory system is provided for presetting a desired PLU code to each of the department keys. When a desired department key is actuated in the direct PLU mode registration operation, the preset PLU code is read out to look up the unit cost stored in the memory area corresponding to the read out PLU code.

Electronic cash register having direct price look-up function

An electronic cash register includes department keys for instructing a department registration operation. A department memory includes a memory area for storing an automatic complex registration number which defines an automatic complex registration operation when a corresponding department key is actuated. A complex registration memory stores a set of desired PLU code numbers related to the automatic complex registration number. Thus, when a desired department key is actuated, the registration related to a plurality of commodities defined by the set of PLU code numbers stored in the complex registration memory is automatically conducted.

An electronic cash register includes a first memory storing a table of upper and lower limits of money amounts defining allowable input ranges of amounts of money during various transactions. A second memory stores codes for defining the upper and lower limits of money amounts for the various transactions by reference to the table of amounts of money stored in the first memory.

Electronic cash register system with input verification

An electronic cash register inhibits registration of information associated with a commodity unless an operator code comprised of a plurality of digits and identifying an operator is inputted. A preset code further allows selection of the manner of indicating and printing the inputted operator code. When an operator code comprised of a plurality of digits is entered by operating a decimal keyboard or ten-key (1) and an operator code key and when a first mode is set through a mode selection key (7), all the digits of the operator code are displayed in a display (11) and printed in a printer (12). If and when a second mode is set, only a predetermined partial digit or digits of the operator code comprised of a plurality of digits are printed and none of digits are displayed. If a third mode is set, both displaying and printing of the operator code are inhibited. Thus, a user can arbitrarily select whether the operator code should be displayed and printed, by switching the mode.

An electronic cash register includes a mode selector for selecting a registration mode or a check and adjustment mode. The memories for the storage of various sales are adjusted during the check and adjustment mode to correct errors. The pre-adjustment information is retained until a clear operation is selected by the operator. A machine-locked condition is established in response to the adjustment operation. In response to the machine-locked condition any key input other than those used during the check and adjustment mode are inhibited. The machine-locked condition is removed when the pre-adjustment information is erased during a clear operation.
