Abstract

PURPOSE:To prevent a key input of an unfair data with an electronic cash register, by inhibiting the key input of a registration data if the key input is not started for the next registration data for a fixed time or longer and permitting the key input if the key input of the next registration data is started within the fixed time. CONSTITUTION:A sign-off process is carried out when a power supply switch is turned on, and a key input is inhibited for input of the sales data of goods. A control switch is set to a registration mode, and a responsible person number is fed through a keyboard 14 to be compared with each responsible person number preset to a memory 3. When the coincidence is obtained, a sign-on process is performed. Then a designated flag is set to the corresponding responsible person number memory, and at the same time a counter 25 of a timer circuit 22 is started. When the sales data is first fed, the flag under registration is set. Then the counter 25 is reset when the second and subsequent key inputs are applied. The counter 25 is reset if the key input is not started for a time longer than a fixed value. Then a sign-out process is carried out, and the counter 25 is released with the input of the set responsible person number.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a registration business lock method in an electronic character register.

[Technical background of the invention and its problems]

In conventional electronic cash registers, if the operator leaves his/her seat while inputting registration data for one customer, he or she manually signs out the machine by pressing a specific key. In addition, signing out means that the registration data that has been entered manually will be saved, and that the entry of keys for future registration data will be prohibited.To release this prohibited state, you will be required to enter your secret number or cashier number. There is. The number at this time must be the same as the number previously input, and an error will occur if the check or payment mode is set to a mode other than the registration mode.

However, in this type of system, if the operator forgets to press a specific key and leaves his/her seat, there is a risk that the registered data may be tampered with by an unauthorized key, which poses a management problem.

Furthermore, in the conventional electronic cash register, after the registration 7'-event key was manually pressed, the machine was signed off when the registration for one customer was completed by pressing the closing key. Sign-off means, for example, that the registration data for one customer is transmitted to a tally device such as a store controller, and key input of the registration data for the next customer is prohibited.To release this prohibited state, a secret number or cashier number is entered. It is supposed to be done. The number at this time may be different from the number entered at the time of registration of the previous customer, and after the number has been entered, inspections other than the registration mode and operations in the settlement mode can be performed.

However, with this type of device, you have to sign on each time you perform the tightening operation for each item, so you have to perform the number taichi every time you perform the tightening operation, which may be a problem when there are many customers. there were.

[Purpose of the invention]

This invention was made to solve such problems, and it is a registration business lock in the electronic thousand cash register that allows for precise management, improves work efficiency, and improves business operations. The purpose is to provide a method.

[Summary of the invention]

This invention stops the key input of the registered data when the key input of the next registered data is not started for a certain period of time or more, and stops the key input of the registered data when the key input of the next registered data starts within the specified time. The key is to allow human power.

The timer circuit 22 is formed by a clock oscillator 23.2, a manual underarm 24, and a clock counter 25, and the counter 25 is reset by the reset signal r from the output port 10, and the counter 25 is reset by the reset signal r from the output port 10, and the counter 25 is reset by the reset signal r from the output port 10.

The high level sign-on signal S from the AND gate 2
4, the counter 25 counts the clock from the clock oscillator 23, and when the counter 25 times out, it supplies a time-over signal t to the input port door.

As shown in FIG. 2, the keyboard 14 has "0" and "
00” “1” to “9” numeric keypad 26, “01” to “
30" department key 27, "Subtotal" subtotal key 28, r
A lock key 29 for the ship insurance policy J, a person in charge key 30 for "responsibility", etc. are provided.

The RAM 3 has five responsible person number memories 311 to 315 including a responsible person designation flag memory 31 as shown in FIG. A flag memory 32 and the like are provided during registration.

The responsible person number memories 311 to 315 can be preset with five responsible person numbers by turning the control switch 16 into the "setting" mode and using the numeric keypad 26 of the key gate 14 and the responsible person key 30. There is.

FIGS. 4 and 5 are flowcharts showing main processing performed by the microprocessor 1. When a power-on operation is performed fL, a sign-off process is performed. This sign-off process prohibits key personnel input for entering commodity sales data. In this state, the control switch 1
6 in the "registration" mode, and if the responsible person number is input from the keyboard 14, it is checked whether the responsible person number is reset in each of the responsible person number memories 311 to 315, and if it is not preset, an error occurs. Make it. Also, if it is preset, sign-on processing is performed. This sign-on process sets a flag in the responsible person designation flag memory 31 of the responsible person number memory in which the inputted responsible person number is preset, and resets the counter 26 of the timer circuit 22 via W capo-no 0. At the same time, the counting operation of the counter 25 is started. In this state, by switching the control switch 16, it is possible to shift to another mode other than the "registration" mode. When the first product sales data is entered manually for the customer, the registering flag memory 32 is not set at this time, so the registering flag memory 32 is set and the counter 25 is reset, toshi, and based on the key's manual input. Perform department registration processing. Furthermore, for the second and subsequent key manpower, department registration processing is performed based on the reset of the counter 25 and the key manpower.

1■.

If the registration flag memory 32 is set and there is no key input for registration, the input port door is controlled to check whether or not the time-over signal t is input from the timer circuit 22.

When the time-over signal t is input to the input port door, the counter 25 is set to 11 and sign-out processing is performed. This sign-out process is similar to the one shown in Figure 5, which prohibits any key input for registration (U) unless the responsible person number is re-keyed. To exit from this sign-out, the responsible person designation flag memory 31
Is it necessary to enter the same responsible person number as the responsible person number in the responsible person number memory that is set? Also, when the closing key 29 is pressed manually to finalize the registration for each item, the closing process such as totaling by manager, total totaling, issuing receipts, displaying change, etc., and resetting the registration flag memory 32 are performed. The drawer opening fold 1172 operates via the output boat 8 to open the drawer 19. After that, when the drawer 19 is closed, the drawer closing detection circuit 21
When the closing of the drawer 19 is detected, a detection signal d is output. This detection signal d' of the detector 91-0 is detected through the input port 2Ti, and the front counter 25 is reset with a reset signal r. When the time-over signal t is input from the counter 25 to the input port door while the registering flag memory 32 is reset, the counter 25 is reset and the person-in-charge designation flag memory 3 that has been set is reset.
1 and performs sign-on processing.

With this configuration, if the operator leaves his/her seat while registering product sales data for one customer, that is, while the registration flag memory 32 is set, the next The timer circuit 22 times out and you are signed out without any key input.

Henceforth, any manual input of keys for registration from the keyboard 14 is prohibited, and there is no risk of unauthorized key input. Thereafter, the operator returns to his/her seat and re-enters his or her manager's number using the keypad 14, and the sign-on status is resumed and registration for the customer can be continued. In this case, moving to a mode other than registration mode is prohibited. In this way, there is no need to perform a specific key human effort to sign out, so there is no need to forget to sign out, and data management for the 4th controller can be performed accurately and efficiently, and the key work is also simplified. .

In addition, if the drawer 19 is opened after closing the check for one customer, and the operator closes the drawer 19 after paying the change, if the operator immediately starts the registration operation for the next customer, the sign-on state will be restored. Continuously buzzing. However, if the operator leaves his/her seat, a time over signal t is output from the timer circuit 22 after a certain period of time, and the sign-on state is established.

In the second sign-off N%, the responsible person designation flag memo 1) 31
is cleared, so in order to cancel this sign-on state, all you have to do is manually key in the responsible person number preset in any one of the responsible person number memories 311 to 31'5. It is also possible to shift to a mode other than registration mode. Even if the closing process is performed for one customer in this way, the sign-off state will not occur immediately, and the sign-off will not occur until a certain period of time has elapsed after the drawer 19 is closed. Sometimes there is a screen 1 where you have to enter the responsible person number for each customer.
There is no additional work required, and the workability can be improved. Furthermore, since you are signed on when you leave your seat, there is no risk of someone using an unauthorized key, and you can manage your system neatly.

〔Effect of the invention〕

As described above, according to the present invention, the timer circuit automatically switches to the sign-out state or sign-off state after a certain period of time has elapsed without any key operation, so that incorrect data may be mixed in the data processed by the operator. There is no risk of damage, excellent management is possible, and work efficiency is improved.
It is possible to provide a registration business locking method for electronic cash registers that is highly effective in practical use.
