Description

[Detailed explanation of the idea] Industrial applications The present invention relates to an electronic cash register.

BACKGROUND OF THE INVENTION Electronic cash registers (hereinafter referred to as cash registers) are installed at the fronts of various stores to perform so-called cash register operations. In such a cash register, the name of the product purchased by the customer, the purchase price, and the department to which the product belongs (for example, oranges belong to the fruit department) are entered using a predetermined code.

In such a cash register, when the type of product on display is changed, etc., the key function change operation (hereinafter referred to as changing the key layout) set to each key of the key input means of the cash register ) must be carried out. Further, cash registers are generally provided with a switch for switching the functional state between a functional state for performing so-called cash register operations and a program functional state for changing the key functions of each key.

FIG. 9 is a flowchart illustrating an operation for changing the key layout of such a conventional cash register. Referring to FIG. 9, after switching the functional state of the cash register to a state where the key layout can be changed as described above, among the programs that can be executed in such a state, a program for changing the key layout is shown. , enter the 3-digit numerical code corresponding to the program in question. Next, in step n2, the "." key is pressed, and then in step n3, the "@/FOR" key is pressed. Next, in step n4, a preset three-digit numerical code representing the desired key function is entered, followed by depressing the desired key on the keyboard.

Through the above operations, the key function specified in step n4 is assigned to the key on the keyboard pressed in step n5. Then follow the above steps
The process consisting of n4 and n5 is repeated to assign a desired key function to a desired key on the keyboard.
When such a key function assignment operation is completed, the "CA" key is pressed in step n6, thereby completing the key layout changing operation.

Problems to be solved by the invention In the conventional cash register described above, the key functions of "0-9", ".", "@/FOR", and "CA" necessary for changing the key layout are , which are assigned in advance to predetermined keys on the keyboard, and which cannot be changed.There has been a demand for expanding the functions of the cash register by making these changeable keys also changeable.

The purpose of the present invention is to solve the above-mentioned problems and to provide a cash register that can significantly increase the number of keys whose assigned key functions can be changed in the key input means of the cash register. It is.

(j) After the key function settings have been assigned, the processing circuit is Reference numeral 2 denotes an electronic cash register characterized by executing the above-mentioned cash register function.

Function In the electronic cash register according to the present invention, the keys 13, 14, 1 provided in the key input means 10 are
5, 18-21 are provided with fixed keys 13, 14 and keys 15, 18-21 whose key functions can be set.
includes the first group of keys 18 to 21, the second group of keys including the department key, and the remaining third group of keys, and for key function setting operations, the fixed keys 13, By turning on the power switch while operating the machine 14, it is possible to prevent the machine from erroneously performing the original operation of the cash register which performs the cash register function.

Further, according to the present invention, the first group of key functions including the numeric keypad is first set, then the department functions of the second group of keys are assigned, and then,
By assigning key functions to the keys of the third group, it is possible to easily change the key functions provided in the key input means 10, and it is also possible to easily change the key functions provided in the key input means 10. Forgetting to set a key function can be prevented as much as possible, thus improving the operability of the cash register, and also preventing forgetting to set a key function.

In addition, the CPU is connected to a printing means 8 realized by a so-called printer, a display means 9 that displays segments using a fluorescent display tube, etc., and a key input device via the control units 5, 6, and 7, respectively. Means 10 are respectively connected. Also CPU
2 includes a key function setting table 11 which has a configuration as described later and is realized by RAM or the like.
is connected.

FIG. 2 is a diagram showing the memory configuration of the cash register 1, and FIG. 3 is a diagram showing the configuration of the key function setting table 11. ROM3 of cash register 1 and
As shown in FIG. 2, the memory map consisting of RAM 4 has addresses as memory area 12.
It has an address space from _0000H to _FFFFH , of which
The address space from _4000H to _7FFFH is a so-called bank.
A plurality of memory spaces are allocated to the ROM based on a so-called bank switching control method.

In addition, the key function setting table 11 includes the input means 1
Key function setting areas 11-1, 11-2, 11-3, .
11-n. This key function setting table 1
For example, each start address of each of the key function setting areas 11-1 to 11-n of 1 is set in a fixed one-to-one correspondence with each key of the key input means 10.

FIG. 4 is a diagram showing the key layout of the key input means 10 of the cash register 1 shown in FIG. 1, and FIG. 5 is a flowchart illustrating the key layout changing operation of this embodiment. The key layout changing operation of this embodiment will be explained with reference to FIGS. 1 to 5. Generally, in the cash register 1, when a power switch (not shown) is turned on without any other operation, a program is immediately activated to realize an operating state in which a so-called cash register operation can be performed. To perform the key layout changing operation implemented in this embodiment, the following master reset operation is performed at step m1 in FIG.

That is, in the key input means 10 shown in FIG. 4, there are two keys as fixed keys, namely, the receipt feed key 13 and the journal feed key 14.
(The journal here refers to the printed paper on which monetary information is printed and stored on the cash register 1 side when the so-called normal cash register function, that is, the cash register function is being executed.) While lowering the power, turn on the power switch mentioned above.

By such a master reset operation, in step m2, the receipt feed key 13 and journal feed key 1 of the key input means 10 shown in the fourth figure are activated.
The key functions set for all the remaining keys except 4 (for example, the key 15 at the lower left corner of the fourth illustrated key input means 10 has a key function of "CB" when pressed).
) are all cleared, and all of these remaining keys 12
, no key functions are set.

At step m3, the count value of the counter 16 provided in the CPU 2 (see FIG. 1) is initialized and returned to, for example, "0".

Such a key layout changing operation is performed by basically dividing target key functions into three groups.
The first group to be changed is "0, 00, 1,... ,9,@/FOR,.,CL,
For example, there are 16 key functions of SBTL, CA.
The second group is department key functions in which department names to which various individual products belong are set, and the third group is the remaining key functions other than the first and second groups.

As described above, when the processing from step m1 onwards proceeds, the cash register 1 first requests a first group of key layout setting operations according to the program stored in the ROM 3. For example, in step m4 of FIG. 5, the display means 9 of the cash register 1
For example, a display like the one shown in Figure 6 will appear, and “0” will appear.
An operation is requested to set the key function to which position of the key input means 10 shown in the fourth figure. The process moves to step m5, and enters a so-called key input waiting state.

Next, in step m6, when the operator presses down a key at a desired position on the key input means 10 shown in FIG.
A different address is given to each key in each location (hereinafter, this unique address is referred to as a hard code and is expressed as a two-digit hexadecimal number A)
Read the register 1 provided in CPU 2.
Store in 7.

Next, in step m7, the CPU 2 determines whether the numerical value A of the hard code stored in the register 17 is greater than or equal to, for example, FD _H. If this judgment result is affirmative, it means that an error occurred in the pressing operation of the key, and the step
At step m8, error processing such as generating an alarm sound is performed, and then the process returns to step m5, where the key input waiting state is reached.

If the judgment result in step m7 is negative, it means that the key press operation was performed correctly, and the process moves to step m9, in which, for example, the first address of each key function setting area in the key function setting table 11 is searched. . In this way, for example, the key function setting area 11-1 can be found. At this time, key function setting area 1
A predetermined code representing a key function already stored in CPU 1-1 (hereinafter this code will be referred to as a function code, expressed as a two-digit hexadecimal number "B") is read and stored in register 17 provided in CPU 2. Store.

Next, the process moves to step m10, where it is determined whether the value "B" stored in the register 17 is " _00H ". Here, as the function code of the key at each arrangement position of the key input means 10 as described above,
" _00H " is not set during the so-called master reset explained in step m1 of this embodiment, but when such a "0" key function is assigned by the key function change operation currently in progress. only has function code “ _00H ”. Therefore, at present, no matter where the key is pressed in step m6, its function code, that is, the value "B" stored in register 17, is
is not " _00H ".

Therefore, the process moves to step m11, and the key function setting area 11-1 of the key function setting table 11 is
A predetermined code representing the "0" key function, for example " _00H ", is written in the key.

Next, the process moves to step m12, where the counter 16
The count value of is incremented by +1. Next, in step m13, it is determined whether the count value of the counter 16 exceeds 16. That is, it is determined whether the number of key functions set as the so-called first group as described above has been exceeded. If the judgment is affirmative, the CPU 2 performs an operation to set the next key function to be set, for example "1", to any key in the arrangement position of the key input means 10, based on the value of the counter 16 which has been incremented by +1. request. That is, the process returns to step m4, and the display on the display means 9 shown in FIG. 6 is performed in which "0" is changed to "1". Thereafter, operations similar to those described above are performed.

Here, in the setting operation after setting the "0" key function, a case will be explained in which the "0" key 18 (see FIG. 4) whose setting was registered in step m6 is pressed. At this time, the judgment result becomes affirmative in step m10, and the process proceeds to step m11.
Go directly to step m12 without moving to step m12. That is, for the key function setting operation that the CPU 2 requests the operator to perform at this time (for example, the "1" key function setting operation), the key function setting area of the key function setting table 11 corresponding to the "0" key 18 is 11-1, no code representing the "1" key function is written, and the counter value of the counter 16 is immediately incremented by +1. In other words, the "1" key function can not be set in the key input means 10. Thereafter, the above-described key function setting operations of the first group are successively performed in this manner.

FIG. 7 is a flowchart illustrating a second group of key function setting operations that are set based on the first group of key functions described above. In the operation described with reference to FIG. 5, the operator uses the so-called numeric keypad that has already been set to input a program number, such as "951", for setting the second group of key functions.
Input in step a1. Next, in step a2,
Again, press the "." key 19 that has already been set, and then press the "@/FOR" key 2 at step a3.
Press down on 0.

In step a4, the operator selects, for example, fresh food,
3 which are set corresponding to each category such as fruit.
Enter the digit code. Next step a5
Then, the user presses down the key at the desired position on the key input means 10 where the department code is to be set. Through this operation, the department function can be assigned to the key.

Alternatively, the "@/FOR" key 20 may be pressed in step a5, in which case the department function is not set and the process moves to step a6. At step a6, the "CA" key 21 (fourth
(see figure), the process goes to step a4.
Return to , move on to setting a new department code, and repeat this step by step.

On the other hand, in step a6, the "CA" key 2
When 1 is pressed, the department code setting operation as described above is completed.

FIG. 8 is a flowchart illustrating the setting operations of the key functions belonging to the third group. step
In b1, enter the code number that starts the program that performs such an operation, for example "950". Subsequently, in steps b2 and b3, the "." key 19 and the "@/FOR" key 20 are pressed down, respectively.
In step b4, enter the 3-digit preset code value representing the desired key function, and then
At b5, a key at a predetermined position belonging to the key input means 10 for which the key function is to be set is pressed down. By this operation, the key function specified in step b4 is assigned to the pressed key.

If the 3-digit code number representing the new key function is input without pressing the "CA" key 21 in the subsequent step b6, the process repeats the process consisting of steps b4 to b5. Any key function can be assigned to a key at any location.

On the other hand, in step b5, "@/FOR"
It is also possible to press the key 20, and in this case, the key function to be set at that point is not assigned to the key input means 10, and the process consisting of steps b4 and b5, or the "CA" key 21 in step b6 is performed. It is possible to move to the operation of In step b6, press the "CA" key 21
By pressing , the setting operation for the third group of key functions described above can be completed.

As described above, in the embodiment, it is possible to layout the key functions of the first group including the so-called numeric keys "0", "1", "2", ..., "9", etc. The operability of such a cash register 1 can be significantly improved.

Effects As described above, according to the present invention, the key input means 1
0 key function configurable keys 15, 18 to 21
is a first group of keys 18 to 21 including a numeric keypad;
It has a second group of keys including a department key for setting a product department name, and a third group of keys including remaining keys,
Fixed key 1 for further performing cash registration functions
3 and 14, in order to execute the money registration function after the key function setting operation, it is only necessary to turn on the power switch without operating the fixed keys 13 and 14, thereby achieving a smooth money registration function. You can also use the fixed key 1 for key function settings.
By turning on the power switch while operating keys 3 and 14, key function setting operations are not performed by mistake, and erroneous operations can be prevented.

Moreover, according to the present invention, the key function setting operation of the first group of keys 18 to 21 can be performed by the display means 9.
The key functions can be sequentially operated one by one while following the display, and the operability is good.
