JPS5813940B2 - Mode designation device in electronic register - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mode designation device in an electronic register.

Conventionally, in this type of electronic register having multiple modes such as "registration,""inspection," and "payment", the mode has been specified using a key switch a as shown in FIG.

However, in this case, since all of the same models have the same key switch a, it is possible to operate the electronic register of the same model even if the user is different, and there is a risk that the key may be misused due to theft or the like.

Furthermore, the rotation range of keys for store managers, cashiers, etc. differs from user to user, and it is technically difficult to accommodate these requests.

Furthermore, the design is affected by the shape and material of key switch a, and because key switch a is made of metal, there are problems such as the negative effect of static electricity on the internal circuit, and also because key switch a and the keyboard may be operated at the same time. This has the disadvantage that the design becomes complicated unless consideration is given to this.

Furthermore, some types of ECH are known to have memories for daily and monthly totals.

When performing "accounting" work with the ECR as described above, after switching the key switch a to "accounting" mode, press the "daily" 24 or "monthly total 125" key on the keyboard 1 as shown in Figure 2. By operating the system, daily and monthly account settlement operations can be performed.

Here, "Payment" means to turn the key switch a to "Payment "Z".
” and a specific star key (daily or monthly total)
This refers to the task of sequentially reading out the cumulative prices and quantities of products stored in the ECR by product, transaction, etc., displaying or printing them, and then clearing these memories.

Therefore, in the ECR mentioned above, if the daily total key 24 or the monthly total key 25 is operated incorrectly, the memory will be automatically erased, which has the drawback of causing a lot of damage to the grasp of sales information. ing.

In view of these points, the present invention provides "registration,""inspection," and "
By assigning code numbers to various modes such as "Payment" and specifying the mode using the number keys and specific function keys on the keyboard, the structure is simple and easy to design because no key switch is used. The mode can be easily specified by a simple key operation, and the code number corresponding to each mode can be set differently for each user or cashier.
Moreover, it is an object of the present invention to provide a mode designation device for an electronic register that can prevent mistakes even when operating different keys in the same mode.

Next, one embodiment of the present invention will be described with reference to FIGS. 2 to 5.

In Fig. 2, a keyboard 1 has touch keys such as numeric keys 2 such as ``0'' to ``9'' and ``00'', function keys 3 such as ``alternate'', and above them rsETJ SET as a specific function key. Each key 4 is provided, and the display 5 includes a department display section 6, an amount display section 7, and mode rungs 8, 9, and 10 corresponding to the four modes of "registration,""inspection,""payment," and "pause J," respectively. , 11 are provided respectively.

Also shown in FIG. 3 are a display controller 15 that controls the display 5 through a take bus 13 and an address bus 14 from the central processing unit 12, a keyboard processing circuit 16 that processes key input from the keyboard 1, and A printer controller 18 for controlling the printer 17 is provided, and a ROM 19 as a storage means for storing fixed data and a RAM 20 as a storage means for storing variable data are provided. Input/output data is being communicated.

In addition, the RAM 20 is provided with a number buffer 21, a 7-link buffer 22, a mode memory 23, and various other memories.
This memory corresponds to each of the four modes of "payment" and "pause" and stores each code number set by, for example, the keyboard 1.

Further, FIG. 4 is a circuit block diagram expressed to facilitate understanding of the operation of the present invention.

In the figure, keys 2, 4, 3, and 24 are on the keyboard 1.
It corresponds to the number key, SET key, alternate key, and date key above.

30 is a "SET" code memory storing a setting code, which is addressed to a specific area of the ROM 19 in FIG.

Similarly, the numeric register 31 and mode memory 23 are RAM
Addressed within 20.

Also flags 32, 33, 37, 46, 47, 48 are R
Addressed within AM20.

Comparator 35 as comparison means, address counter 38,
Memory processing circuit 39, decoder 45 and AND gate 34
, 36, 40, 41, 43, 44, 49 and the OR gate 42 are replaced by the functions of the central processing unit 12 and ROM 19 in FIG.

Also, tecoder 45 and flags 46, 47, 32, 48
and constitute a mode selection means.

Next, with reference to FIGS. 4 and 5, setting of code numbers for various modes and a mode designation method using the code numbers will be explained.

When setting a code number, the setting code is first set to a "setting" state, that is, a pre-sentable state. The setting code for this is stored in advance in the 'SET' code memory 30 area fixed in the ROM 19, and this setting code is After entering a number using the number key 2 on the keyboard 1 and temporarily storing it in the number register 31, press the SET key 4.
When the various memories in the AM 20 have been cleared, that is, the AND gate 34 opens in response to the non-set output Q of the 2 flag 32 and the set output of the numeral flag 330, and thereby the numeral data and setting code are cleared. A comparison is made by the comparator 35, and if the setting code is correctly input, the AND gate 36 is opened and the SET flag 37 is set to enter the "setting" state.

In other words, the flow shown in Figure 5 is A, B, C, C, and O.

Note that, if a switch exclusively for "setting" is provided without using a setting code, the "setting" state can be similarly set by turning on the switch and pressing the SET key 4.

Next, enter the code number corresponding to each mode using the numeric key 2, temporarily store it in the numeric register 31, and then press SET.
When the key 4 is pressed, the AND gate 34 opens in response to the non-set output of the Z flag 32 and the set output of the set i flag 330, and the comparator 35 first compares the set number with the set code. is different from the setting code, the comparator 35 outputs an rNO- signal, and this rNOJ
Upon receiving the signal, the set output of the SET flag 370, and the output of the M gate 34, the AND gate 49 opens and instructs the address counter 38 to output a write address.

Therefore, the data in the number register 31 is written to the mode memory 23, for example, the "REG" code memory, via the memory processing circuit 39.

In other words, the flow shown in Figure 5 is A, B, C, Work, Power, and Ki.

Repeat this four times to set the code numbers for the four modes. At this time, the method of memorization is as follows: [Registration (REG) Jr. Inspection (X) Jr. Settlement (Z) J [Stop (LOCK) J] It may be determined and stored sequentially by specifying the write address of the address counter 38.Also, if the number of digits to be entered is, for example, 4 digits and the first digit is 1, "Register (REG)"
J, if the first digit is 2, "Inspection (X)", if the first digit is 3, "Payment (Z)", if the first digit is 4, [Stop (LOCK)]
)J may be used to determine the position of the mode memory 23.

In this manner, by pressing the SET key 4 after entering the code number, the entered number data is stored in the corresponding predetermined mode memory 23.

Simultaneously corresponding mode lamps 8, 9, 10, 11
lights up to indicate that the code number for that mode has been set.

Furthermore, if printing by the printer 11 is added, the set code number remains as a memory.

When the code numbers for all four modes have been set, the "setting" state is canceled, but the specified function key 3 (in Fig. 2, it also serves as the "alternative" key) is used for this purpose. By pressing , it is determined that the SET is completed, the AND gate 40 is opened, and the SET flag 37 is
will be reset and the "setting" state will be released.

That is, the flow shown in Figure 5 A, H, and Q is taken.

Next, in normal operation, enter the set code number for the mode to be specified using the numeric key 2, and then press the SET key 4 to set the numeric flag 33 and output the Z flag 32. Upon receiving the set output and the non-set output of the SET flag 37, the AND gate 41 opens and gives a read address command to the address counter 38 via the OR gate 42.

As a result, first, the contents of the REG code memory of the mode memory 23 are given to the comparator 35 and compared with the contents of the numeric register 31, but if the comparator 35 is
”, the AND gate 43 opens,
Advance the address in the address counter 38.

In this way, the set number data and the code number in the mode memory 23 are compared, and a matching code number is searched for.

In this way, when the read code number matches the digit data, the rYEsJ signal is output from the comparator 35, and the A
The ND gut 44 is opened, and one of the flags 46, 47, 32, and 48 whose mode is selected and specified by the read address of the address counter 38 is set via the decoder 45, and the mode specified by the numeric key 2 is set. is declared.

At the same time, corresponding mode Langs 8, 9, 10, 11
lights up and the mode is displayed.

That is, the flow shown in Figure 5 is A, B, C, S, C, and S.

Further, in the embodiment described above, code numbers are associated with various modes, and the code numbers can be set freely by the user, but the code numbers are not limited to this, and may be fixed in advance by the manufacturer.

In this case, the mode memory 23 is not required in the RAM 20, and code numbers corresponding to each mode are fixed in the ROM 19. In other words, no operation is required to set the mode code, and the code number is determined in advance when specifying the mode. Enter the code number on keyboard 1 and then press SET.
When key 4 is pressed, a corresponding mode such as "registration" is designated.

Furthermore, in this embodiment, the settlement (Z) is shown for the daily account, but two mode memories 23 are provided, one of which is
By assigning two code numbers, one for the "mortar meter" and one for the "monthly meter," you can operate the daily and monthly totals by entering different code numbers before starting payment.

According to the present invention, in an electronic register having multiple modes such as "registration,""inspection," and "payment j," a code number is associated with each of the various modes, and these code numbers are used to control the number keys and W on the keyboard. Since the mode is specified using the function key of the keyboard, the structure is simple and the design is easy because the conventional key switch is not used and the key is also used as a touch key on the keyboard. Modes can be easily specified by simple key operations, code numbers corresponding to various modes can be set differently for each user or cashier, and different key operations in the same mode will not be mistaken. Furthermore, by making it possible to preset code numbers corresponding to various modes using the numeric keys and specific function keys, different code numbers can be freely preset to suit the user. This prevents the user from operating the machine.

In addition, it is possible to prevent mistakes such as accidentally operating the "daily" and "monthly" in the same mode "accounting".

In addition, a setting code is provided that commands the preset enable state, and by entering this setting code with the numeric key and pressing a specific function key, the preset state is set.Number data set by the numeric key By moving to a flow for selecting a mode when it is determined that the code does not match the setting code, the operation is simple, the design is easy, and the circuit configuration is also simple.
