DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for recording a key operation of a keyboard and error information resulting therefrom.

[0002]

2. Description of the Related Art In recent years, many devices have an input unit equipped with a display and a keyboard. When the device is in an abnormal state, if the operator recognizes an operation error, the device can cope with the abnormal state. Is easy, but the operator often does not recognize the operation error.

[0003]

In such a case, it is very difficult to distinguish whether the operation is an error or a device has a bug (error in a program), and it is troublesome to deal with an abnormal state. Many. In addition, in the case of an operation error or misrecognition of an operation, it is not only difficult to recognize the operation, but it is often very difficult for the operator to recognize the operation error. If there is a bug in the apparatus, it is necessary to reproduce the abnormal state, determine the cause, and remove the cause. However, an abnormal state often occurs only when a specific operation is performed, and in such a case, it is very difficult to reproduce the abnormal state and to determine the cause.

The present invention has been made in view of the above-mentioned problems, and provides a key operation recording method which records a key operation and related information, and facilitates investigation of a cause when an abnormal state occurs. The purpose is to:

[0005]

In order to achieve the above object, means for holding input information from an input means, and an input means
Of the screen displayed on the display means during input operation from the column
Means for holding surface information, and
Combines error information with retained input and screen information
Means for storing the information .

[0006] The input information is a pressed keyboard.
The screen information is the screen code of the display screen.
The error information is an error code,
Record the key operation history by combining the three codes.
It is something to remember .

[0007]

According to the above configuration, when an error occurs, the error information and the input which caused the error are displayed.
Not only can you record whether you have entered force information,
The screen information when the input information is input is also recorded.
Thus, the cause of the error can be understood, and it becomes easy to plan an error prevention measure.

[0008] Even if the same input information is input, the screen information
If the information is different, a different error may occur, so that error analysis can be easily performed in such a case. In particular, the key code of the keyboard on which the input information was pressed
Hardware, the same key is different on each display screen.
Even if it is assigned to the meaning, this key code
Screen information can be specified by the stored screen code.
The stored key code and error code.
Can understand the meaning of the word exactly.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of this embodiment.
1 is a display unit, 2 is a keyboard, and an operator presses a key corresponding to display contents of the display unit 1. A print unit 3 prints out the output. 4 is a display control unit for controlling the display unit 1, 5 is a key control unit for controlling the keyboard 2, 6 is a print control unit for controlling the printing unit 3, 7 is a ROM storing programs and data, 8 is a RAM, An MPU 9 controls the entire system. In addition, the input from the input means of claim 1
Screens displayed on means for holding information and display means
The means for holding the screen information of the MPU 9
An input register from the input means according to claim 1, which is an internal register.
Error information at the time of cropping together with input information and screen information
The means for storing is the RAM 8.

Next, the operation will be described. Keyboard 1
Key is pressed by the key control unit 4
U9 starts creating a key log. The MPU 9 requests the key code of the pressed key from the key control unit 5 and stores the key code sent from the key control unit 5 in an internal register. Next, the display controller 4 requests the screen code of the screen displayed when the key is pressed, and stores the screen code sent from the display controller 4 in an internal register. Next, MPU9
Creates a key log by combining the key code stored in the internal register with the screen code and the error code written in the RAM 8, and writes the key log in the RAM 8. Here, the error code is always rewritten to the latest state. The key log is stored in the RAM 8 in a fixed amount set in advance, and the excess amount is discarded from the oldest one. The stored key log is printed out from the printing unit 3 in response to a request.

FIG. 2 shows an example of printing a key log. In the figure, a key code, a screen code (DISPCODE), and an error code are described from the left, and the latest operation is displayed at the top. The state from 11 steps before is recorded, and until 4 steps before, the error code is 00 and no error has occurred. However, in step 3, when the key "01" was pressed with the screen code "2D", an error "04" occurred. The key "1" is displayed on the automatically switched display screen "09".
Pressing "E" switches to the menu screen "0A", making a key log output request with the key "1E", receiving this output request, and outputting it as a key log list from the printing unit 3. The key "1E" depressed in 2 is physically the same key but has a different screen, so that it is clearly recorded that the depression was performed in a completely different sense, which is useful for error analysis. In addition,
The printing example shows an example of 11 steps, but in the present embodiment, 128 steps are used.
The key log of the step is left.

[0012]

As is apparent from the above description, the present invention not only uses error information and input information but also screen information.
Error analysis can be performed accurately and easily.
It is possible to pursue the cause of the error and take measures to prevent the error.
Is beneficial for.
