Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an information processing device, and more particularly to an information processing device in which keys on a keyboard can be set.

[Conventional technology] Stores, etc. have electronic cash registers (hereinafter referred to as electronic cash registers) that register product prices and quantities for products purchased by customers.
(referred to as CR) has been installed.

Various ECRs have been known in the past, but some of them require initial setting of keyboard keys when first installed in a store. In such an ECR,
Select the initial setting mode using the mode changeover switch for selecting the operating mode, and press any key on the keyboard corresponding to each number from 0 to 9, the key corresponding to each alphabetic character from A to F, or the alphabetic key. Definitions were given to the enter key, which indicates the break in number input, the total key, which indicates total calculation, and the current/total key, which indicates change calculation.

[Problems to be Solved by the Invention] As mentioned above, in conventional ECRs, the operating mode can be changed to the initial setting mode simply by switching the mode changeover switch. There were times when I would end up selecting another operating mode.

Even if the initial setting operation is performed in a mode other than the initial setting mode, the keys cannot be set correctly.

Therefore, the main object of the present invention is to provide a key setting function that allows the operator to carry out the initial setting correctly by making the operator conscious of selecting the initial setting mode when selecting the initial setting mode. An object of the present invention is to provide an attached information processing device.

[Means for Solving the Problems] The present invention is an information processing device in which keys on a keyboard can be set, and the keyboard includes a plurality of keys that are not defined in advance.

The information processing device includes a determining means for determining whether any key on the keyboard has been pressed a predetermined number of times in succession, and a setting means for defining the keys on the keyboard in response to the output of the determining means. Prepared and configured.

[Operation] According to the present invention, in order to enter the initial setting mode, the operator needs to continuously press any key on the keyboard a predetermined number of times. This ensures that the operator is conscious of selecting the initial setting mode when selecting the mode.

[Embodiments of the Invention] An ECR will be described below as an embodiment of the present invention, but it should be pointed out in advance that this invention is not limited to ECRs, but can be applied to any information processing device that has a keyboard. .

An ECR according to an embodiment of the present invention is composed of a combination of parts prepared in advance. FIG. 2 is a diagram showing the parts used to construct such an ECR. As shown in FIG. 2, the parts that make up the ECR are the control box 1. Keyboard 2. Printer 3. display 4
．． These include a card reader 5 and a cash box 6. Keyboard 2. Printer 3. A plurality of types of display 4 and cash box 6 are prepared, and by combining them with control box 1 according to an order, a desired ECR can be supplied. The displays 4 include a customer display 41, an operator display 42, and a large display 43 capable of displaying a large amount of information.

Here, the key contents of the prepared keyboard 2 are not predetermined, but can be set according to the order when the ECR is shipped from the factory or installed at the user's store. It looks like this. Examples of keyboards are shown in FIGS. 3 and 5. These keyboards have keys arranged in a matrix.

The keyboard 21 shown in FIG.
Ten keys are arranged in the direction, and the keyboard 22 shown in FIG. 5 has twelve keys arranged in the X direction and six keys in the Y direction.

4 shows the key code of each key of the keyboard shown in FIG. 3, and FIG. 6 shows the key code of each key of the keyboard shown in FIG. 5. When you press a key, the key code corresponding to that key is output from the keyboard, but as explained later, before initial settings, the key code is not associated with the content of the key or the meaning of the key. .

Figure 7 shows an EC constructed by combining the parts shown in Figure 2.
FIG. In FIG. 7, ECRIO is comprised of a control box 1, a keyboard 2, a printer 3, a customer display 41, an operator display 42, and a cash box 6. A mode selection switch 24 as shown in FIG. 8 is provided near the key group 23 of the keyboard 2. The mode selection switch 24 is
This is for selecting the R operation mode, and can be switched to OFF position, S position, P1 position, P2 position, X position, and Z position. When switched to the OFF position, the power is turned off.
When the position is F and switched to the S position, initial settings are enabled, and when switched to the PL, P2°X and 2 positions, application programs can be operated.

FIG. 9 is a schematic block diagram showing the main electrical configuration of the ECR used to perform initial settings. In FIG. 9, the ECRIO is provided with a CPU II for controlling the operation of the ECR.

The CPUI 1 has the above-mentioned keyboard 2. Mode selection switch 24. In addition to the operator display 42, the RO
M12 and RAM13 are connected.

The ROM 12 stores an operating program for CPUI 1 based on a flowchart as shown in FIG. 10 later. R
AM13 includes an area for storing information specifying the content of the key for each key code.

The operation of writing key contents into this storage area will be explained later.

FIG. 1 is a diagram for explaining the operation of an ECR according to an embodiment of the present invention. When ECRIO is powered on, the CP
The UI 1 determines whether the mode selection switch 24 is switched to the S position. When the S position is selected, the system shifts to PS (power-on special) mode and performs various operations according to key operations on the keyboard.

For example, if the same key is pressed seven times in a row, fundamental key settings or key initialization is enabled. Fundamental key setting involves assigning "0" to "9", "A" to "F", "Clear", "Enter" or other function keys to each key on the keyboard.

Also, from the keyboard 2 defined by the fundamental key setting, "1""1"1"1",
When "Enter" is input, initial setup is performed. Initial setup loads application programs and system programs,
Furthermore, in the case of an ECR that has a communication function with other devices, initial settings for communication must be performed.

Furthermore, from keyboard 2, “0”, 0” “0”O”
When "Enter" is input, self-diagnosis is performed and "2" is input.
“2”, “2”, “2” When “Enter” is input, the input/output devices etc. are checked, and “9”, ’9”,
If “9”, “9” “Enter” is input,
Perform a memory check using a debugger.

In this ECR, initial clear (ICL) is performed as a process when the power is turned off and then restored during operation.
, auto clear (ACL) can be selected.

Initial clear is performed on RAM13 when the power is restored.
Auto clear means to continue operation while retaining the memory contents of the RAM 13 when the power is restored. Initial clear is selected by switching the mode selection switch 24, which is in the S position when the power is turned on, to a position other than the S position, and auto clear is selected when the mode selection switch 24 is in the S position when the power is turned on. It is selected when the selection switch 24 is in a position other than the S position.

FIG. 10 is a flowchart for explaining key operations for performing the fundamental key setting shown in FIG. 1. Next, the fundamental key setting operation will be explained with reference to FIGS. 1 to 10.

When the power is turned on, the CPU II determines whether the mode selection switch 24 has been switched to the S position, and if it has been switched to the S position, the CPU II shifts to the PS mode. In the PS mode, a counter that counts the number of times a key is pressed is cleared to O in step S1.

Subsequently, in step S2, the key buffer that stores the key code of the operated key is cleared.

Here, when performing fundamental key setting, the operator presses any key on the keyboard 2 seven times in succession. The CPU 11 waits until a key is pressed, and each time a key is pressed, it reads the key code corresponding to the pressed key. In step S3, when one key code is read, step S3
Proceed to step 4 and the counter that counts the number of key presses will be 0.
It is determined whether or not. If it is "0", the process advances to step S6 and the counter is incremented by one. Subsequently, in step S7, it is determined whether the counter has reached "7". In this case, the counter is “1”.
", so the process returns to step S3.Furthermore, when the key is pressed and the key code is read, it is determined in step S4 that the counter is not "0", so
In step S5, it is determined whether the key code is the same as the previous key code. If a key different from the previous key has been operated, the process advances to step S9, and key read processing is performed to perform a sequence different from the fundamental key setting.

On the other hand, if the same key as the previous one is operated, the counter is incremented by one in step S6. When the same key is pressed seven times in a row in this way, the process advances to step S8, and the fundamental key setting program is started.

Next, fundamental key setting will be explained. Fundamental key setting is the definition of the keys on the keyboard as described above. For example, a case will be explained in which keys for inputting "0" and "enter" are defined. In this case, "0 key?" is displayed on the operator display 42. The operator selects one of the keys on the keyboard as the key for inputting "0" and presses that key. As a result, the pressed key functions as the O key. Further, for example, when "Enter key?" is displayed, if a key used as an enter key is pressed, the pressed key functions as an enter key.

In this way, after performing fundamental key sorting, for example, “1”, ′1”1” “
1" and "Enter", the initial setup operation shown in FIG. 1 is performed.

As described above, in this embodiment, the mode selection switch 2
Fundamental key setting can only be performed when the key is placed in the S position and the same key is pressed 7 times in a row. You can prevent incorrect settings like this.

[Effects of the Invention] As described above, according to the present invention, since the initial settings are made consciously, the initial settings can be performed correctly.
