Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the method for issuing the key function changes of the cash register of the present invention according to the preferred embodiment.

3 is a diagram showing a part of a table specifying initial data set for each key. As shown in this figure, each of the keys has a key number indicating a mounting position on the keyboard and a key name associated with an operation performed through key input, and is used for setting a function of a key or changing a setting character in a program mode. A function code is assigned.

An example of a key function change setting will be described with reference to the table of FIG. 3 as described above.

For the convenience of the user, when the key assigned to the key number "24" is set to perform the function of "cash key", first, select the program mode through the mode selection switch, and then, among the various setting operations that can be performed in the program mode, Key Function Change To select a setting operation, input the numeric keys "1", "0", "2" and "4" in order, and then press one of the function keys, "Enter key".

After the key function change setting operation is selected, the key designated as the key number "24" by entering the numeric keys "2" and "4", that is, previously used as "X / clock key" as shown in FIG. Select the old key.

Then enter the function code "1" and press the "Enter key" and optionally enter "Item 1 key" or "Item 2 key", which is a predetermined key to save or delete the previous entry, and complete the change setting. Or cancel.

Through the above-described procedure, a key previously used as an "X / clock key" performs a function of a "cash key".

4 is a view showing an example of a document output as a result of the method for issuing the key function change contents of the present invention applied to the cash register, and FIG. 5 is a flowchart illustrating the method for issuing the key function changes contents of the cash register according to the present invention. to be.

Referring to the flowchart of FIG. 5 and the aforementioned drawings, the procedure for issuing a method for issuing a key function change of the present invention will be described in detail as follows.

The key function change content issuing method of the cash register of the present invention preferably includes a part of the key function change setting process described above as an example.

Therefore, in step S10, it is determined whether the mode selected by the mode selection switch 32 provided in the current keyboard is a program mode.

If a mode other than the program mode is selected as a result of the determination in step S10, the process proceeds to step S12 where tasks that can be performed in the mode are progressed or waited.

However, if the determination result in step S10 is that the program mode is selected, the process proceeds to step S14 to determine whether or not the key function change setting operation is selected among various setting operations that can be performed in the program mode.

If a job other than the determination result key function change setting job is selected in step S14, the flow advances to step S16 to perform the job.

However, if the discrimination result key function change setting operation is selected in step S14, the flow advances to step S18 to receive a key number and a function code as shown in FIG.

The key number input in step S18 is for designating a key mounted at a predetermined position on the keyboard, and the function code is for changing the type of work performed by the key designated as the key number.

In the step S20 after the execution of the step S18, in order to be cautious in setting the key function change, it is again determined whether or not the change is to be set by the change inputted in the step S18.

If a key for canceling the determination result change setting in step S20 is inputted, the process proceeds to step S22 to delete data temporarily entered in the step S18 and temporarily stored in the RAM 50.

However, if a key for accepting the change result of the determination in step S20 is inputted, the process proceeds to step S24 and the temporary buffer provided in the RAM 50 to implement the present invention in step S18. Store in

In step S26 after performing step S24, it is determined whether or not the key function change setting is to be ended.

If the determination result in step S26 is to change the function of another key without ending the key function change setting, the process proceeds to step S18 to receive a corresponding key number and function code.

However, if the determination result in step S26 is to terminate the key function change setting, the process proceeds to step S28, in which initial data set on all keys provided on the keyboard, that is, the previous setting value and the step S24, are input to the temporary buffer. It is determined whether or not the recorded change set values are identical.

If the determination result in step S28 is that the previous setting value and the change setting value for any key do not match, the flow advances to step S30 to output the change as a document through the printer 20.

When the key having the key number "24" functions as the "cash key" as changed in the above-described key function change setting operation, as shown in FIG. 5, the key number of the key and the previous key name The X / clock key and the previous function code "27" and the newly entered contents of the key name "cash key" and the function code "1" are output.

After performing step S30, in step S32, the previous setting value is updated with the changed setting value and stored in the corresponding storage area.

On the other hand, when the determination result in step S28 is the same as the previous set value and the change set value, the step S10 without going through the change content document output operation in step S30 and the update storage operation such as step S32 Proceeds to end this routine.

The term 'step' used in the detailed description of the present invention reveals that the term 'step' may not be semantically consistent with the term 'step' used in the claims.

As described above, according to the method for outputting the key function change contents of the present invention, when the function of the key provided on the keyboard of the cash register is changed according to the user's usage environment, the user can publish the change contents as a document. It is easy to grasp and avoid the mistake of key operation and improve the work efficiency.
