Abstract

PURPOSE:To realize a lot of functions in the same work mode with few keys by selecting a function code concerned from a key setting table based on the selection condition code of a selection condition memory when multi-function keys are key-inputted. CONSTITUTION:When the multi-function keys 87a-87e on a keyboard 8 are key-inputted, the function code concerned is selected from the key setting table 41 based on the selection condition code of the selection code memory 42 and the key input processing of the multi-function key concerned is executed based on the selected function code. When the new selection condition code is generated by the processing operation, the new code is stored in the selection condition memory 42. When the multi-function keys 87a-87e are key-inputted, the other function code is selected and the key input processing based on the function code is executed. Thus, plural functions can be alloted to the multi-function keys 87a-87e without providing a shift key although processing operation timing differs even in the function of the same work mode.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to an electronic cash register having a keyboard provided with so-called multi-function keys that realize multiple functions with one key.

[Prior Art] Some conventional electronic cash registers have a key for declaring the end of registration for one customer in the registration mode, such as a deposit/account key, and a key for declaring the end of inputting setting data in the setting mode. It is known that the key can also be used as a key.

For example, in Japanese Patent Publication No. 1-43357, a keyboard is provided with a plurality of product keys and a classification key for switching the functions of these product keys, and in the registration mode, the function of each product key is changed to a classification key (shift key). A technique is disclosed in which switching is performed based on key input.

[Problems to be Solved by the Invention] As described above, in conventional electronic cash registers, it is known that the keyboard is provided with a multi-function key, that is, a key in which multiple functions are assigned to one key.
These multi-function keys must be assigned functions in different business modes, or if they are assigned functions in the same business mode, it is necessary to operate the shift key to switch functions.
Without providing a shift key, it was not possible to set multiple functions for the same business mode on a multi-function key.

Therefore, the present invention provides an electronic cache that allows multiple functions in the same business mode to be assigned to one multi-function key without the need for key operations of the shift key, and that can realize many functions in the same business mode with a small number of keys. It is intended to provide a register.

[Means for Solving the Problems] The present invention provides an electronic cash register that has a keyboard for inputting information on sales products, etc., and registers product sales data in a memory based on information input from the keyboard. In addition to providing a multi-function key on the keyboard, a key setting table in which multiple function codes are set corresponding to the key hard code of this multi-function key, and a selection condition code determined according to the current processing operation are provided. a selection condition memory for storing; a code selection means for selecting a corresponding function code from a key setting table based on a selection condition code in the selection condition memory when a multi-function key is keyed; and a function selected by the selection means. The multifunction key processing means executes key input processing of the multifunction key based on the code, and a plurality of functions having different processing operation timings in the same business mode are assigned to the multifunction key.

[Function] In the electronic cash register of the present invention configured as described above, when a multi-function key on the keyboard is inputted, the corresponding function code is selected from the key setting table based on the selection condition code in the selection condition memory. is selected, and key input processing for the multi-function key is executed based on the selected function code. When a new selection condition code is generated by the processing operation, the new code is stored in the selection condition memory. Thereafter, when the multi-function key is input, another function code is selected and key input processing based on the function code is executed.

Therefore, a plurality of functions can be assigned to a multifunction key without providing a shift key, even if the functions are in the same business mode, as long as the processing operation timings are different.

It is effective for

On the other hand, the ROM 3 stores program data and the like for the CPU to execute processes corresponding to various business modes.

The RAM 4 is formed with a memory for registering product sales data obtained based on information related to sales products input via the keyboard 8. As shown in FIG. 2, there is also a key setting table 41 in which 28 types of function codes and selection condition codes are arbitrarily set corresponding to the key hard code of each key arranged on the keyboard 8; A selection condition memory 42 is formed to store a selection condition code determined according to the processing operation.

Here, in the registration mode, the selection condition code S1 is stored in the selection condition memory 42 during idle time until sign-on is performed, and the transaction with the previous customer is completed or canceled and the product registration of the next customer is performed. During the preprocessing up to this point, the selection condition code S2 is stored. In addition, the selection condition code S3 is stored during the declaration process from the start of product registration for - customers until the closing operation is performed, and the selection condition code S3 is stored during the registration process until the closing operation is performed. Condition code S4
is memorized. -Furthermore, the selection condition code S5 is stored during the closing process after the closing operation is performed, and the selection condition code S6 is stored during the post-processing after the sign-off is performed.

Furthermore, arbitrary data can be set in the key setting table 41 in advance. Here, multi-function key 8
For 7a to 87e, the function code that matches the smaller selection condition code among the two function codes assigned to that key is set in the first function code area, and the smaller selection condition code is Set in the selection condition area.

On the other hand, for keys other than multi-function keys, the only type of function code assigned to that key is set in the first function code area, and the code SO indicating a single function is set in the selection condition area. It has become so.

The CPU is programmed to execute the process shown in the flowchart of FIG. 4 when a key input on the keyboard 8 is detected while the registration mode is selected by the mode switch 6. That is, first, the key hard code corresponding to the input key is obtained via the keyboard circuit 9.

Then, use the key hard code to set the key setting table 41.
Perform a search. As a result, if a corresponding key hard code is set in the table 41, the selection condition code corresponding to the key hard code is acquired. Here, if the corresponding selection condition code is SO, the input key is a single-function key, so the first function code corresponding to the key hard code is obtained, and the key processing according to that function code is performed. Execute. Thereafter, if the selection condition code is updated by the key processing operation, the contents of the selection condition memory 42 are changed to the updated code and the process is ended.

On the other hand, if the selection condition code of the key hard code corresponding to the input key is 51 to S6, the multifunction keys 878 to 87
Since this is a key input of e, the selection condition code stored in the selection condition memory 42 is read. If the selection condition code stored in the memory 42 is equal to or smaller than the selection condition code of the key hard code corresponding to the input key, the first function code corresponding to the key hard code is acquired. On the other hand, if the former selection condition code is larger than the latter selection condition code, the second function code corresponding to the key hard code is acquired. (
(Code selection means) After that, key processing is executed according to the acquired function code, and if the selection condition code is updated by the key processing operation, the contents of the selection condition memory 42 are changed to the updated code ( multi-function key processing means),
This process ends.

In this embodiment configured as described above, the multi-function key 878 is assigned an exchange key function and a transaction stop key function. Here, the exchange key function is the selection condition code S.
