Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an electronic cash register, and more particularly to an electronic cash register having a transmission section and capable of transmitting data to and from a central processing unit.

Data transmission between multiple cash registers (terminals) and a central processing unit (referred to as a data aggregation machine or consolidator) can be carried out by, for example, aggregating the registered data of each terminal in the central processing unit, or transmitting data from the central processing unit to each terminal. This is done when setting date data etc.

By the way, there are cases where it is desired to use each terminal in a so-called offline mode, in which it is separated from the central processing unit.

To switch from online mode to offline mode,
It is preferable to use software with leads such as a changeover switch.

An object of the present invention is to select an online mode or an online mode in each terminal depending on whether or not a connection number (address number) for each terminal necessary for communicating with a central processing unit is set.

To summarize, this invention provides a memory in each terminal for setting the connection number used for communication with the central processing unit and the unique number (register number) of the cash register, and checks whether the connection number is set in this memory or not. to select online and online mode.

If the online mode is selected, the registration data is transmitted to the central processing unit and then the payment process is performed, and if the offline mode is selected, the payment processing is performed without transmitting the registration data to the central processing unit. We are making it possible to do this.

The present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a block diagram of a cash register (terminal), in which numeral 1 denotes an arithmetic processing unit constituting a control means provided with an arithmetic processing unit and a program.

2 is a keyboard, 3 is a display section, 4 is a memory, 5 is a printer, and 6 is a transmission section (modem).

FIG. 2 shows a detailed view of the keyboard 2.

Reference numeral 21 denotes a mode selection switch, which allows selection and setting of registration mode, mortar mode for processing returns, etc., settlement mode, setting mode, etc.

Among these modes, the registration mode and date mode can be selected and set using a key held by the clerk in charge of registration, but the payment or setting mode cannot be selected unless the manager uses another key.

22 is various function keys, 23 is a numeric key, 2
4 indicates each transaction key.

Figure 3 shows connection number setting area 3 provided in a part of memory 4.
1 and register number setting area 32.

A three-digit connection number is set in the connection number setting area 31, and a four-digit register number is set in the register number setting area 32.

The connection number is used as the address number of the terminal when communicating with the central processing unit (not shown), and when the connection number is not set, the setting area 31 is all O's.

(Figure 3a) - When a connection number is set in the power setting area 31, a call signal (
When a polling signal) is given, the number of the ringing signal (
Data transmission takes place between the central processing unit and the terminal set with the connection number that matches the polling address.

The register number is an identification number unique to a cash register, also called a machine number, and is printed along with the registration data when issuing a receipt, etc. so that it can be later determined from which cash register the receipt was issued.

Both the connection number and the register number are set manually using keys from the keyboard 2, but the mode selection switch 1 is set in the setting mode so that only a specific person, for example, an administrator such as a manager, can set the settings.

When using the online mode, the key sequence for setting is to enter a 7-digit code using the numerical keys and then operate the transaction keys.

In response to this operation, the first three digits of the code are set in the connection number setting area 31, and the remaining four digits are set in the register number setting area 32.

(Figure 3b) On the other hand, when using online, enter a 4-digit code using the numerical keys and then operate the transaction key field.

The input 4-digit code is in the register number setting area 32.
, and the connection number setting area 31 remains at all O's at this time.

Next, an example of how the connection numbers and register numbers set in each memory area 31 and 32 are used will be explained with reference to the flowchart in FIG.

When performing settlement processing at each cash register,
The registration data previously stored in the memory is printed by the printer 5.

After that, the registered data in the memory is cleared.

If the terminal performing the checkout process is in online mode, the registration data must be aggregated in the central processing unit (consolidator) before the memory is cleared.

A hauling selective signal is sequentially given from the central processing unit to each terminal, and each terminal sends registration data to the central processing unit at its assigned time.

As a specific example of payment processing, first set the mode selection switch to payment mode on each terminal, then press transaction key 42.
Operate Koji.

Subsequently, it is determined whether the numbers set in the connection number setting area 31 are all O's, and when the determination result is YES, it is determined that the offline mode is in effect, and therefore, the registered data in the memory is printed and cleared to finish the payment process. .

However, if the determination result is NO, this means that the mode is online, and transmission processing to the central processing unit is performed.

(Fig. 4a) As mentioned above, each terminal can transmit data with the central processing unit only during the allotted time, and therefore each terminal waits for the holing-selefting signal to be given from the central processing unit. ing.

The central processing unit gives a common hauling selecting signal to all connected terminals, and only terminals whose connection numbers are not all O receive their own connection number set in the memory area 31 and the polling signal given by the central processing unit. Compare.

Then, data transmission is started between the terminal with the matching connection number and the central processing unit, and the registered data stored in the terminal is aggregated in the central processing unit.

(Fig. 4b) According to the present invention, there is a connection number that is necessary as a terminal identification number when communicating with the central processing unit, and a register number that is printed as an identification number unique to the cash register when issuing a receipt. (machine number)
Since the online mode and online mode can be selected depending on whether or not the connection number is set, it is possible to select either mode using software without the need for extra hardware such as a changeover switch. becomes.

Additionally, if the terminal that performs the payment process is in online mode, the payment process is performed after transmitting the registration data to the central processing unit, so the central processing unit can collect data reliably without missing any data. becomes.
