Description

ELECTRONIC CASH REGISTER

This utility model relates to the field of automation and computer technology and can be used to build electronic cash registers.

Known electronic keyboard computing machine (USSR Author's Certificate N 1068945, class G06F 15/02, 1982) containing an input unit, a synchronization unit, a microprogram control unit, an arithmetic device, a memory unit, a print control unit, a print unit.

The known device has limited capacity and limited functionality.

The closest technical solution is an electronic cash register (Europatent N 527423, class S076 1/12, publ. 02.17.93 (prototype), containing a processing and control unit, non-volatile random access memory, read-only memory, keyboard unit, display unit, indication control unit, print unit, address register, data and control bus, keyboard control unit.

The known device has wide functionality, but an excessive amount of equipment.

The achieved effect of this utility model is the implementation of wide functionality with a limited amount of equipment.

In the future, the utility model is illustrated by a description of a specific embodiment of the device. given in the drawing.

-f

non-volatile memory 3, read-only memory 4. register 5

addresses, block 6 control keyboard and indication, block 7

indications, block 8 keyboard, single-tape block 9 print, block

10 sound alarms, control bus 11, data bus 12.

The device can operate in three modes.

Calculator mode without printing. In this mode, the device operates as a normal calculator. In this case, a set of numbers and commands is carried out in block 8, converting them into data and addresses in block 6, transferring them to block 1, register 5, memory 2.4. The calculation results are transmitted through block 6 to block 7 and are recorded in memory 2. Control, synchronization of address formation, call and recording of data in memory is carried out by block 1.

Calculator mode with print. It differs from the previous one only in that at each stage all numbers and operations are printed on paper tape.

The main mode of operation of the device is cash register mode. In this mode, the design and functional features of the device are manifested. The presence in block 9 of only one tape does not allow at the same time with the work check to print the control check. Therefore, an intermediate storage of the data of a check in memory is provided. However, the printing of a check is mandatory. This can be done either after each work check,. either after the accumulation of a group of work checks, or based on the results of equipment operation for a selected period of time, for example, a working day.

control check. Such information is the number of sellers (cash register operators), check number, control tape number, total amount for sellers, for a group of checks. These and other similar information are recorded in memory 3. Standard information such as the cash register number, date, and others are recorded in memory 2. When using the cash register, the information in these memories is shared, which can significantly expand the functional amount of information.

In addition, to work on the cash register, you need to dial an individual operator number and the corresponding password. If a password is dialed that does not match the dialed number, the error is fixed and a repeated dialing operation is required. In this case, block 10 is activated and gives a signal. If earlier another operator worked on the cash register and knocked out checks, but did not print the control code, then when a new operator is registered, the control check of the previous one is automatically printed.

After the work is completed, the operator must exit registration to exclude access to the cash register of unauthorized persons. To do this, print a check.

When the device is operating, information and addresses are transmitted via bus 12, and control signals via bus 11.

Thus, the claimed cash register allows you to process and record more extensive functional information with less equipment. Reducing the amount of equipment is ensured by the use of one tape in the print unit and the addition of an electronic circuit with only one memory unit.
