Description

[Detailed Description of the Invention] (i) Technical Field of the Invention The present invention is based on a key input control method, and particularly relates to a key input control method in an automatic transaction device comprising a plurality of input/output sections and one control section. It is.

(ii) Technical background An automatic transaction device is divided into an input/output section such as a card reader CIP, passbook printer PRU, cash counter CCU, bill validator BDU, etc., and a main control section that controls the entire transaction. It is now possible to control multiple input/output units using the main control unit of the stand.

This automatic transaction device is now widely used in banks and the like.

(iii) Prior art and problems Figure 1 shows a conventional example. In the figure, 0 is a control unit, 1 is a main control unit, 2 is a key input control unit, 3 is a transmission control unit, 5 is a key input I/O unit, 6 is a distributor,
7 is the key input unit side transmission control unit, 13 is the keyboard unit, CIP is the card reader, PRU is the passbook printer,
CCU is a cash counter, BDU is a bill validator, and IOX is an input/output control unit.

First, the main control section 1, which issues commands to each input/output section in order to control the progress of processing and transactions, issues a command to the key input control section 2 to designate an operation mode according to the type of transaction. Upon receiving the command, the key input control section 2 selects the key necessary for the transaction to be performed in the relevant operation mode, and notifies the key input I/O section 5 of the selected key. When the key input I/O unit 5 receives the key selection signal, the key input I/O unit 5 notifies the user by displaying the keys necessary for the transaction on the display provided in the keyboard unit 13, and also removes unnecessary keys at each stage of the transaction. Control is performed so that keys are not accepted even if they are input. Then, the keyboard section 1 is
The data input from the key No. 3 is transmitted to the key input control section 2 via the transmission control section 7 on the input/output section 4 side, the transmission control section 3 on the control section 0 side, and the distributor 6.

Here, each input/output unit (keyboard, CIP, PRU, CCU, BDU) on the control unit 0 side and input/output unit 4 side is connected by a single signal line, so data is exchanged while transmitting data one by one. Because I was doing this, my time was wasting away. Also, while one data is being transmitted, another data is transmitted from the key and cannot be received, so the user cannot receive the data by pressing the key rapidly in succession, so it is difficult to receive the data by pressing the key one by one. I had to press it, which was a pain.

In particular, the following problems arose: This is because the data sent from the key input I/O unit 5 to the control unit 0 is data that cannot be re-entered (for example,
Unit data “10,000”, “1000” when commanding amount input
Even if double transmission can be prevented by checking whether the data is already sent (such as
It was troublesome that the control unit 0 side had to check whether or not the data was permissible, and if the data type was not permissible, it had to refuse to accept it.

(iv) Object of the Invention The object of the present invention is to eliminate the above-mentioned drawbacks, provide a system configuration that can keep up with even high-speed key inputs, and lighten the burden on the control unit during transfer.

(v) Structure of the Invention An object of the present invention is to provide a key input control method for an automatic transaction device that is composed of a plurality of input/output units including at least a keyboard and a control unit that controls the input/output units as a whole. Storage means for sequentially storing data with valid display data appended to it for each predetermined unit, and verifying the validity of the valid display data appended to the data at the timing of sequentially reading data from the storage means and sending it to a control unit. The input/output section includes a transmitting means, and an invalidating means for receiving data sent from the control section and invalidating matching valid display data among the valid display data stored in the storage means, and the control section The department side is provided with re-input recognition means that stores the data sent from the transmission means, verifies the type of the data, and notifies the input/output unit of the type of data that should be prohibited from being re-entered. This is achieved by a key input control method featuring the following.

(vi) Examples of the invention The present invention will be explained in detail below using the drawings.
FIG. 2 shows an embodiment of the present invention. In the figures, the same numbers as in the previous figures indicate the same things. 4 is a key input I/O section 5 and other I/O sections (for example, CIP,
8 is a transmission section, 9 is a reception section, 10 is a key input processing section, 11 is a key interrupt reception section, 12 is an encoder, 14 is a queue which is a storage means, 15 is an input pattern storage unit; 16 is a cancel determination unit which is invalidation means;
17 is a key interrupt control section, and 18 is a key buffer section. In addition, 13 is a keyboard section, which includes general-purpose function (transaction mode type) keys 13-1 for specifying passbook entry, cash payment, transfer, etc.
Numeric keys 13-2, function keys 13-3 such as 10,000, 1,000, yen (transaction unit), and approval/cancellation (◎/×) are provided.

Below, before explaining the operation, an overview of each function will be explained.

(a) The main control section 1 first issues a command to the key input control section 2 in order to enable input using various keys on the keyboard 13 according to the type of transaction. This command includes general function key 13-1.
, a selection input with the "×;Cancel" key enabled, numeric key 13-2, a password input with the "x" key enabled, numeric key 13-2,
“10,000”, “1000”, “Yen”, “◎; Approval”, “×” Key 1
Enter the amount to make 3-3 valid, “◎” key,
There are confirmation inputs that enable the “x” key.

(b) Upon receiving the command, the key input control unit 2 selects the keys necessary for the process (that is, the key input control unit 2 selects the keys necessary for the process (that is, the key input control unit 2 selects the keys necessary for the process)
(can be specified for each function key such as "1000", "Yen", etc.), and thereby each input command (selection input,
The key input control unit 2 notifies the key input I/O unit 5 of each key validation/invalidity instruction (key selection signal) each time (password input, amount input, confirmation input).

At the same time, the type and procedure of keys to be operated by the user are displayed on the display provided in the keyboard section 13 to inform the user.

(c) When the key input I/O section 5 receives the key selection signal from the control section 0, it gives the key interrupt receiving section 11 valid/invalid instruction data for each key individually.

(d) The key interrupt reception unit 11 stores the user input keys notified from the encoder 12 in a table (not shown) in which enable/disable instructions for each key sent from the key input control unit 2 are stored. , it is checked whether each key has been designated as valid, and if so, the key input processing section 10 is notified. On the other hand, if invalidation is specified, the input data is ignored.

For example, if the operation mode of the transaction is "payment", the main control unit 1 issues an instruction to input the amount,
Number key 13-2 and function key 13-
3 Enable the “10,000”, “1000”, “Yen”, “◎”, and “×” keys. Since the operation guide at this time is displayed on the display, the user can input the amount of money he/she wishes to withdraw by pressing the number keys and function keys.

(e) Input data from the keyboard section 13 passes through the encoder 12 of the key input I/O section 5 and is notified to the keyboard interrupt reception section 11. If it is determined that the interrupt is valid for each individual key, it is sent to the key input processing section 10, stored in the queue 14, and sent from the transmission control 7 via the transmission section 8 to the transmission control 3 on the control section 0 side. , and is recognized by the key input control section 2 of the control section 0.

Now, the operation will be explained in detail in the case where the main control section 1 issues an instruction to input an amount of money.

The command is displayed on the display in a separate system (not shown), and at the same time, the contents of the transaction record to be performed are stored in the input pattern storage section.

Keys required for amount input command (numeric keys 13-
2. Function key 13-3 “10,000”,
“1000”, “yen”, “x” keys) are sent from the key input control unit 2 to the key interrupt reception unit 11 and the key interrupt control unit 1.
7 is notified as a valid key.

Since the amount input guide is displayed on the display, the user inputs the amount he/she wishes to withdraw using the inputtable keys on the keyboard section 13.
For example, if you want to withdraw "123,000 yen", "1", "2", "10,000", "3", "1000", "Yen"
The keys are pressed in this order, and input to the key interrupt reception unit 11 via the encoder 12 in this order.

In response to the numeric key inputs "1" and "2", the key interrupt accepting unit 11 uses a table (not shown) in which the valid/invalid instructions for each key are stored. refer. In the amount input command, the key input control unit 2 selects the numeric key 1.
3-2. Since the function keys 13-3 "10,000,""1,000,""yen,""◎," and "×" are notified as valid keys, the input numeric keys "1" and " 2” is enabled, and the key input processing unit 10
queue 14 with valid display data.
"1" and "2" are stored in this order.

This queue 14 includes a buffer section that sequentially stores input data from the keyboard 13 in predetermined units, a flag section that indicates whether the data stored in the buffer section is input data from a key that is displayed as valid. It consists of a counter that counts the amount of data stored according to the buffer size.

Now, when data "1" and "2" are sent from the key input processing section 10, valid display data is added to each data and stored in the buffer section. The counter counts "2" since two data "1" and "2" are stored.

Next, the data stored in the queue 14 are sequentially read out, and the validity display data attached to each data is checked again to see if it is valid, and if it is valid, it is sent to the control unit 0 side.
Every time one piece of data is transmitted, the data stored in the buffer section of the queue 14 is shifted to the location where the sequentially transmitted data was located, together with a valid flag, and the counter is set to "-1". Count.

After being output from the queue 14, it is transferred to the transmission control unit 3 on the control unit 0 side, the distributor 6, and the key input control unit 2 via the transmission unit 8 and the transmission control unit 7, and is transferred to the key buffer unit 18 as “1”. ”, “2”
Sort and store the data in this order.

Next, "10,000" is inputted from the function key 13-3 after the numeric key 13-2, which is similarly transferred to the key input control section 2 and stored in the key buffer section 18. Now, the key interrupt control unit 17 checks whether this "10,000" is data that can be re-entered for cash payment.

In contrast to the number keys 13-2, which allow repeated inputs, the function keys 13-3, ``10,000'', ``1000'', and ``yen'' keys, must be input once and then invalidated. It won't happen.

Therefore, the key interrupt control unit 17 determines whether key data can be re-entered or not, and when data that cannot be re-entered is input, it immediately invalidates the subsequent input of the corresponding key. The key input control unit 2 sends a signal to invalidate this “10,000” key data.
The key input I/O unit 5-side receiving unit 9 is notified through the key input I/O unit 5 side receiving unit 9 to select the key, and the cancel determination unit 16 which is the invalidating means and the key The interrupt reception unit 11 is notified.

Subsequently, "3" is inputted using the numeric key 13-2 after the "10,000" data, and is similarly stored in the key buffer section 18.

Next, when "1,000" is entered in the function key 13-3, the key interrupt reception section 11 checks whether the "1,000" key is valid, and if it is confirmed to be valid, the key is inputted via the key input processing section 10. It enters the queue 14, and the cancel determination section 16 checks again whether the "1000" key is valid, and if so, the transmission section 8...
“1” and “2” are sent to the key buffer section 18 via
Store “1,000” after “10,000” and “3”.

By the way, data such as "10,000/1000" is stored in the key buffer 18, and before a signal is sent from the key interrupt control section 17 to the key interrupt receiving section 11 to prohibit the use of the "10,000/1000" key from now on. , the "10,000/1000" key is pressed again from the keyboard 13, and the data may be stored in the queue 14. However, the cancel determination unit 16
Then, the input data stored in the queue 14 is
It is checked whether the data is the same as the data corresponding to the above-mentioned prohibition signal, and if the same data is recognized, the valid display input data is set as invalid display, so there is no fear that it will be sent to the control unit 0 side. In the above case, since the "10,000" and "1,000" keys were used once each, the key interrupt reception unit 11 and the cancellation determination unit 16 determine that these two types of key inputs will not be accepted. do.

Finally, "yen" is input, and when the input ends, a completion notification is issued from the key input control section 2, and the main control section 1 performs the next process.

Now, if the user presses the "X" key in the middle of key entry to restart the key entry, all previously entered data will be cancelled. This is because when the "x" key data passes through the key interrupt reception section 11 and is sent from the key input processing section 10 to the queue 14, the cancellation determination section 1
6, the data is recognized and “x” is placed in the queue 14.
All valid indications attached to data stored before the data are invalid indication data,
This is because it prevents the data from being sent to the control unit 0.

(vii) Effects of the Invention As explained in detail above, according to the present invention, even if key interrupts (inputs) become faster, a storage area called a queue is provided, so key inputs can be performed quickly. It is possible to configure a system that can keep up with the speed even when the speed is changed, which saves time.

You can also change key input, enable and disable keys, and
Since this is carried out on the O side, the burden on the control section is lightened.
