Abstract

PURPOSE:To attain an optional use of an electronic cash register for plural responsible persons by providing plural responsible person keys and setting a code number to each responsible person. CONSTITUTION:A responsible person A feeds his/her code number by a ten-key 10, and this input code number is stored in an A resister 33. Then an A key 13a of a responsible person key 13 is pushed, and a subtractor 43 subtracts the responsible person code stored in an A preset area 34 from the value stored in the resister 33. Then a cash register is opened when the result of subtraction is set at ''0''. a responsible person B opens the cash register to reset a flag RSF40 when the person A opens the register and sets it in a register state. Then the release is prevented for the register state of the person A. Thus it is possible for each responsible person to operate the cash register independently from each other. The number of responsible persons sharing a single electronic cash register can be increased by increasing the number of keys 13, set areas and flags respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an electronic cash register that performs management functions for each person in charge.

(Off) Prior Art In conventional electronic cash registers, in order to register data for each person in charge separately, a plurality of buttons lock type switches or specific There are known key switches that the person in charge recognizes by rotating in the direction of the key, or key switch systems that output a code for the person in charge of the key just by inserting it.However, these push switches or keys The switch method is expensive, and the button switch method has the disadvantage that the switch of another person in charge may be pressed by mistake or intentionally.Also, the key switch method has the problem that keys are easily lost, When a large number of electronic cash registers of the same type are used on the same floor, as in the case of a case where a number of electronic cash registers of the same type are used, there is a drawback that one key can be used in common. There is also a known method, but in this method, when the IT contributor leaves his/her seat, the person in charge operates the cancel key, erases the person in charge code that is being operated, and waits for the next person to enter the person's code. Since the system is configured to be in a standby state, if the person in charge temporarily leaves his or her desk or forgets to press the cancel key, it is prohibited for another person in charge to enter the person's code manually in order to use it. The following drawback is that it cannot be used arbitrarily by multiple responsible persons because it will cause an error.

(C) Item P9 The present invention) A new manager management function that eliminates the above-mentioned drawbacks and can be used by multiple managers at will. The object of the present invention is to provide an electronic cash register with the following functions.

Next, the fourth factor of the construction of the present invention will be explained in detail according to the flowcharts shown in FIGS. 5 and 6.

First, please enter the responsible person code number 5 before starting the registration process.
The data is stored according to the processing procedure shown in the flowchart in the figure. To memorize the responsible person code number, first set the mode control lock (9) Ik: setting task (ps), and then enter the 94-digit responsible person code number using the numeric keypad + 1 (l) on the keyboard (2). When ・ is input manually, the input data is stored in the A register, and at the same time the flag NF (177
"1" is stored in the display 1611'' and the responsible person code number is displayed. Next, when the A key (15a) of the responsible person key 031 is pressed, "1" is set in the flag NF and the Since the responsible person code number of the digit is set, the contents of the A register Q are transferred to the preset area diagram, and the responsible person code number of the responsible person A is stored. Also, by pressing the B key (13b) of the person in charge key a3 according to the same procedure, the person in charge code number of the person in charge B is stored in the B preset area 4.

Next, the operation for starting the registration process after storing the responsible person code for each responsible person in the electronic cash register in advance in the electronic cash register will be explained based on the flowchart shown in Figure 6. Registration? To start, first set the o-le lock (9) to the Registration position (Reg), then enter the code Z of the person in charge of registration to open the electronic cash register. It is necessary to set it to a state where it can be registered.

For example, when person A enters his or her own person code number by hitting the numeric keypad on the keyboard (2), the person in charge code number entered manually is stored in register A, and the flag NPCiη is set to ``1''. Eki tlreru. Next, press the person in charge key (131 A key C15eL) h: to move to step 7A. Subtract the person in charge code number stored in the reset area diagram from the number stored in the 7A register digit. is performed by the subtracter J! unit f43, and the calculation result is stored in the iB register (sub)). If the result is rOJ, rlJt- is stored in the flag AF (to). That is, when the pre-stored responsible person code number is input and the 9th code JI matches, the electronic cash register is opened so that the responsible person A can use it.

At this time, if the next code number manually entered does not match the pre-stored code number of the responsible person A), an error will occur. This prevents people from using it without permission.

If you press the A key (15a) again with the magnetic cash register set and opened, the flag AFq will change to
1", so move to step) and flag NFG7 is set to "
0", so "1" is stored in the flag RSF (40) and the registration becomes possible. Then, the first customer's registration starts using the registration keyboard (2).

At the start of registration, by operating the department key etc. following the input of the amount, the process moves to step (to) and registration is performed, and when the total key (12a) is operated at the end of the registration, the total memory is Following the process, a receipt is issued and the registration of the first customer is completed.

At this time, by operating the total key (12a), flag I (SF (4)
“0” is stored in α and reset. Therefore, next time when you start registering the second customer, first operate the responsible person key A or - (15a) i to set the flag L-ISF+40 to enable registration, and then do the same as described above. 2
You can do it sequentially for registration 1 after the first person.

Next, when the person in charge A finishes the registration and leaves the seat,
Enter the person in charge code number manually from the keyboard (2) again.
When you press the A key (15aJ'), the code number entered is compared with the code number stored in advance in the same manner as described above, and if they match, the flag AFL and NPC17+ are set. Set "0" to close the operation of the electronic cash register by person A. Therefore, even if another person operates without permission, various key operations on the keyboard (2) will be impossible. .AM of the above procedure is shown in FIG.

By operating the B key (13b) of the person in charge key 03 in the same manner, the person in charge B can register. In this case, even if the person in charge A is using the
Regardless of the status of person A, person B can independently open and close an electronic cash register. In other words, the flag RS F (4α) indicating the state where registration is possible is configured to be reset with the total key (iza), and when registering, the person in charge key (I311k::) is always operated and set to the registered state each time. By doing this, for example, when person A opens the station and is in the green state, flag R3F+40 is reset when person B opens and prevents person A's registration status from being canceled. The responsible person can operate the cash register alone.By increasing the responsible person key A3, preset areas, and flags, it is possible for multiple responsible persons to use one electronic cash register. (f) Effects As described above, the electronic cash register of the present invention allows a person to input a code number that matches a code number stored in advance in a preset area for each person in charge, and then operate the person in charge key. By doing so, you can declare that any person in charge can perform the registration operation, manually enter the person in charge code number again after the registration process is completed, and then operate the person in charge key to prohibit registration fraud 1. It is structured so that it can be done with simple key operations.Therefore, there is no need to install interlocking switches, key switches, or special cancel switches for each person in charge. Even if you forget to operate the registration route, the next person can use it independently regardless of the operation, so it is easy to use and has a great effect on getting rid of prisoners.
