Abstract

PURPOSE: To surely perform the tests of all the test object keys by adding the data for check of an operation input key to an addition part every time a key operated and inputted for the first time is detected and notifying the termination of a key input test mode when this addition value is matched with a set total value. CONSTITUTION: Whether a key is inputted in a key input test mode for the first time or not is automatically decided based on the tested flag F on a flag memory 33. In the case of the key inputted for the first time, the data 1 for check which is preliminarily set to a test object key is added to a counter memory 34. Therefore, the total number of the key operated for the first time is counted in a counter memory 34. In the total storage part 32 of a ROW, the total number X of all the keys on a keyboard is preliminarily set as the total of data for check. When the data of the counter memory 34 is matched with the total number X, the termination of a key input test is notified to an operator by a display, etc.

Has checked the input key and the output key code to check whether the operation key is operating normally.

[0003]

However, in the above-mentioned conventional key input test apparatus, since it is not possible to distinguish between the keys that have been tested and the keys that have not been tested, which key was tested by the operator? It is necessary to remember exactly, and if you make a memory mistake, you may end the test with an unchecked key left.

Therefore, according to the present invention, all the keys to be tested can be surely tested even if the operator does not remember which key has been tested, which reduces the burden on the operator and ensures high reliability. An object of the present invention is to provide a key input test device capable of executing a key input test.

[0005]

According to the present invention, there is provided check data setting means for setting check data respectively for a plurality of test target keys arranged on a keyboard, and for each test target key by this setting means. The total storage unit for storing the check data set in advance, the adding unit for adding the check data, the start declaring means for declaring the start of the key input test mode, and the key input by this declaring means. Clear means for clearing the addition part when the start of the test mode is declared, key code output means for outputting the key code corresponding to the input key when the key to be tested is keyed in the key input test mode, and the key When the key to be tested is pressed in the input test mode, that input key is first input in this key input test mode. Key input judging means for judging whether or not it is a key, and when it is judged that this is the first key input by this judging means, the checking data setting means adds the checking data set for the input key. Check data adding means for adding to the data of the adding section, data comparing means for comparing the data of the adding section with the data of the total storing section, and this comparing means confirms that the data of the adding section matches the data of the total storing section. And an end notifying means for notifying the end of the key input test mode.

[0006]

According to the present invention having such a configuration, the total of the check data set in each of the plurality of test target keys arranged on the keyboard is stored in advance in the total storage section. To test the keyboard, first declare the start of the key input test mode. Then, the addition unit is cleared. Then, the test target keys are input one by one. Then, the key code corresponding to the input test-target key is output, so confirm that it is functioning normally. Also, when it is determined that the input test target key is the first input key, the check data set for the input key is added to the data of the addition unit. Therefore, when the test of all the test target keys is completed, the data of the addition unit matches the data of the total storage unit. At this time, since the end of the key input test mode is notified, the operator does not need to memorize which key was tested.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In this embodiment, a case where a key input test device of the present invention is installed in an electronic cash register as an electronic device provided with a keyboard will be described.

FIG. 1 is a block diagram showing a main structure of an electronic cash register of this embodiment. This electronic cash register has a CPU (central processing unit) 1 as a control unit main body. In addition, a ROM (read only memory) 2 in which fixed data such as program data for controlling the CPU 1 is stored in advance, and sales data such as the number of sales of each product registered for sale and the amount of sales are sales registration processing. RA in which a memory area for
It is equipped with M (random access memory) 3.

Further, the electronic cash register receives a signal from the clock circuit 4 and the mode switch 5 for clocking the system date and time, and at the same time, a drawer opening device 6 for opening a drawer for accommodating cash from the CPU 1. For an I / O port 7 that sends a drive signal according to a command, a keyboard controller 9 that controls the keyboard 8 and takes in key data corresponding to an operation key, a front display 10 for an operator, and a customer-side display 11 for a customer A display controller 12 for controlling data display, a printer controller 14 for controlling a printer 13 for printing data on receipt paper and journal paper, etc. are mounted.

Then, the CPU 1, the ROM 2 and the RA 2
The M3, the clock circuit 4, the I / O port 7, and the controllers 9, 12, and 14 are electrically connected by a bus line 15 such as an address bus and a data bus.

The mode switch 5 is a switch for selectively switching various business modes such as "registration", "inspection", "settlement", and "setting". By the way, "Registration" means that the sales data of each product registered by entering the product code etc. is aggregated and the payment data registered by inputting the deposit amount and payment method is aggregated in the storage unit. This is the mode of business to be performed.

Further, "inspection" is a mode of operation in which data accumulated in the storage section by "registration" is output as an inspection report, and "settlement" is aggregated in the storage section as in "inspection". After outputting the data settlement report,
The mode of work for clearing the data in the storage unit, "setting" is a mode of work in which data necessary for executing various works such as "registration" is set in the storage unit in advance.

As shown in FIG. 2, the keyboard 8 is provided with a numeral key 21 for inputting numerical data such as an amount of money.
In addition to a plurality of department keys 22 in which department codes for classifying each product are preset, various keys such as a subtotal key 23, a current total key 24, a clear key 25, a receipt feed key 26, a journal feed key 27, and a cancel key 28 are also included. A key is provided.

Now, this electronic cash register is
All the keys arranged on the keyboard 8 are used as test target keys, and a key input test mode is selected by the mode switch 5 so that a key input test for testing whether these test target keys operate normally can be performed. Can be selected. Here, the mode switch 5 functions as a start declaring means for declaring the start of the key input test mode.

Further, as shown in FIG. 3A, a key code table 31 storing key codes corresponding to the key data of all the keys arranged on the keyboard 8 is preset in the ROM 2. In addition, a total storage unit 32 is set in which the total number X of all keys is stored in advance as the total of check data. That is, in this embodiment, the check data is set to "1" for all keys.

Further, as shown in FIG. 3B, the RAM 3 has a tested flag for identifying whether or not it has been tested for each key code corresponding to all the keys arranged on the keyboard 8. A flag memory 33 for storing F and a counter memory 34 as an adding unit for adding the check data are provided.

Thus, the CPU 1 is programmed so as to execute the processing shown in the flowchart of FIG. 4 when the key input test mode is selected by the mode switch 5.

That is, first, in ST (step) 1, the tested flag F of each key stored in the flag memory 33 is reset to "0" to bring it into an untested state. Further, as ST2, the count value A of the counter memory 34 is cleared to "0" (clear means).

Next, at ST3, the operation of any one of the keys on the keyboard 8 is awaited. In this state, when the key data is fetched through the keyboard controller 9, the key code table 31 is referred to as ST4, and if the key code corresponding to the key data is read out, it is displayed on the front display 10 (key. Code output means).

Next, as ST5, the flag memory 33 is set.
Is checked to check the tested flag F corresponding to the key code. Here, when the flag F is set to "1", the key that has been operated and input has already been tested in the key input test mode of this time, and the key has been input twice or more. Return to ST3 without performing
Wait for next key operation input. On the other hand, the same flag F
If is reset to "0", the key input by operation is a key that has not been tested in the current key input test mode and was input for the first time, so the flag F is set to "1" at ST6. Tested (key input judgment means).

Next, as ST7, the counter memory 3
The check data “1” for the key which is operated and input this time is added to 4 (check data adding means).

Next, as ST8, the counter memory 3 is
The data A of No. 4 and the data X preset in the total storage unit 32 are compared (data comparison means).

If they do not match, the test of all the keys arranged on the keyboard 8 has not been completed, and the process returns to ST3. On the other hand, data A and data X
If the and match, the test of all the keys arranged on the keyboard 8 has been completed, so in ST9, the front display 10 displays a message notifying the normal end of the key input test, and this process is executed. End (end notification means).

If the data A becomes larger than the data X in ST8, it is considered that the system is abnormal. Therefore, it is preferable to configure the program so that an error message is displayed on the front display 10. Further, as means for notifying the normal end of the key input test, not only display but also printing or buzzer sound may be used.

As described above, in the electronic cash register of this embodiment, when testing whether or not each key of the keyboard 8 operates normally, after the operator selects the key input test mode with the mode switch 5, Keyboard 8
All the keys as the test target keys arranged above are selected and pressed one after another. Then, the key code of the operated key is displayed on the front display unit 10. Therefore, the operator compares the pressed key with the displayed key code to confirm that the pressed key is operating normally. .

At this time, it is automatically determined based on the tested flag F on the flag memory 33 whether or not the key pressed as an internal process is the first key input in the current key input test mode. Then, in the case of the key input for the first time, the check data “1” preset for the test target key is added to the counter memory 34. The counter memory 34 is cleared to "0" when the key input test mode is selected by the mode switch 5. Therefore, the counter memory 34 counts the total number of keys operated for the first time in the current key input test mode.

In this embodiment, the total number X of all keys on the keyboard 8 is preset in the total storage section 32 of the ROM 2 as the total check data, and the data in the counter memory 34 is the total number. When the number X matches, the operator is notified of the completion of the work of the key input test this time by a display or the like.

Therefore, according to the present embodiment, when the key input test is performed, when the test of all the keys arranged on the keyboard 8 is completed, the operator is automatically notified of the end of the key input test. Therefore, even if the operator does not remember which key has been tested, all the test target keys can be tested reliably. Therefore, the burden on the operator is reduced, and a highly reliable key input test can be executed, which improves the practicability.

In the above-described embodiment, when the key to be tested is keyed in the key input test mode, the flag memory 33 serves as means for determining whether or not the input key is the first key input in the current key input test mode. However, the present invention is not limited to this. For example, the key code of the key input in this key input test mode is stored in the RAM.
3) Store and store in the buffer above, and every time there is a new key input, it is searched whether or not the key code of the key exists in the buffer, and when it does not exist, it is judged that it is the first key input. May be.

Further, in the above-mentioned embodiment, "1" which is common to all keys is set as the check data set for each of the plurality of test target keys arranged on the keyboard 8. However, for example, a different value for each key is used as the check data. You may set as. By doing so, when an attempt is made to end the test with an untested key left, the difference between the data set in the total storage unit 32 and the added value of the check data added in the counter memory 34. You will be able to guess to some extent which keys have not been tested.

Besides, it is needless to say that various modifications can be made without departing from the scope of the present invention.

[0032]

As described above in detail, according to the present invention, the total of the check data set in each of the plurality of test keys arranged on the keyboard is stored in advance and the check data is added. An adder is provided, and the check data of the operation input key is added to the adder every time the key input for the first operation in the key input test mode is detected, and the key is added when this added value matches the set total value. Since the end of the input test mode is notified, it is possible to reliably test all the keys to be tested even if the operator does not remember which key was tested, reducing the burden on the operator. It is possible to provide a key input test device that can perform a highly reliable key input test.
