Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a data input device such as an online counter data input device that inputs data using a numeric keypad or the like and updates a center's account file online.

Conventional Technology Conventionally, this type of online counter data input device has a system that prevents unauthorized access to the center's account file by unauthorized persons while the operator is away from the desk. There are means for this. The means for this is a key switch type, in which if the operator turns off the key switch, removes the key, and leaves the room, the operation cannot be performed unless the same key is used;
Alternatively, the operator code type is often used, in which the operator's number (operator code) is registered in advance in the device, and the device cannot be operated unless the operator code is input. (Unexamined Japanese Patent Publication No. 58-221428)
(See Japanese Patent Publication No. 55-41580).

Problems to be Solved by the Invention However, with the above-mentioned conventional counter data input device, it is possible to use the device easily if one has the same key or knows the operator code. There were serious problems in terms of security. In addition, this type of system is configured so that the operator code can be registered using almost the same operations as normal business processing.
There were similar problems with security.

The present invention solves these conventional problems, and aims to provide an excellent data input device that does not allow users to use the device simply by having the key or knowing the operator code. This is the purpose.

Means for Solving the Problems In order to achieve the above object, the present invention uses an away key and a person in charge key, and enables the device for the first time based on the correlation between their on/off states and a separately set password. It is configured so that it can be controlled in a usable state.

According to the present invention, if the device is once rendered inoperable by operating the leave key, in order to make it possible, the leave key must be operated again.
If you do not enter the pre-registered PIN, it will not become operational, and if you enter the PIN incorrectly several times, it will forcibly stop working, making it impossible for unspecified people to operate it at all. This has the effect of significantly improving both security and crime prevention.

Embodiment FIG. 1 shows the configuration of an embodiment of the present invention, and FIG. 2 shows a more detailed configuration of the control section. 1st
In Figures 1 and 2, 1 is a keyboard consisting of a numeric keypad, a function key, etc., and is used for inputting normal data signals, passwords, etc., 2 is a key for a person in charge, and keyboard 1 and key 2 are for gate circuits, respectively. Connected to 4. Among the outputs of the gate circuit 4, the password signal a and the specific number signal b are configured to be supplied to the state control circuit 5 together with the output of the away key 3 that disables key input while away from the seat.
The data signal c is configured to be supplied to the main control circuit and memory 7. The state control circuit 7 generates a guard signal d and a lock signal e, which are connected to a display 8, a main control circuit, and a memory 7, respectively.
It is also connected to the input terminal of the OR gate 6, and its output terminal is connected to the gate circuit 4. 9 is an alarm that issues an alarm when the main control circuit and memory 7 are in a locked state; 10 is an output unit that prints out the operator's operation record, processing details, etc.; 11
is a line control unit for communicating with the center, which is connected to and controlled by the main control circuit and memory 7, respectively.

Next, the operation of the above embodiment will be explained. In the embodiment described above, when the leave key 3 is operated in the work executable state, the state control circuit 5 generates a guard signal d, which is input to the gate circuit 4 through the OR gate 6, and the leave key 3 is activated. Disables all keystrokes until restarted. At the same time, the display 8 displays a guard state in which all key inputs are disabled and business execution is impossible. If the leave key 3 is operated again, the guard state is released and key input is possible, but business processing is not possible in this state. Subsequently, the gate circuit 4 recognizes that the pre-registered password is input, and the state control circuit 5 releases the guard state based on the password signal a generated as a result, making it possible to execute the business. If the input PIN number is different from the one registered in advance, it is regarded as an incorrect input, and if the PIN number is input incorrectly several times, the state control circuit 5 generates a lock signal e, and the gate circuit 4 activates a certain specific password. Inputs other than numbers are disabled, and the main control circuit and memory 7 lock the entire device and put it in an alarm state. Therefore, in this state, the buzzer in the alarm device 9 sounds, and the control of the output section 10 and circuit control section 11 is stopped. This alarm condition is configured to continue even after the device is powered off and turned on again. In the alarm state, when the person in charge key switch 2 is turned on and a specific number is keyed in, it is recognized by the gate circuit 4, the specific number signal b is input to the state control circuit 5, and the state control circuit 5 outputs the lock signal e. The occurrence is stopped and the alarm state of the main control circuit and memory 7 is canceled. Accordingly, this causes the buzzer to stop ringing and the key input is possible. Business can be resumed by further inputting the PIN number.

When a specific number is keyed in in the state where business execution is possible, the password registered in the gate circuit 4 becomes another signal f via the state control circuit 5 and is displayed on the display 8 by the main control circuit and memory 7, and this state Turn on the responsible person key switch 2 and operate the clear key provided on the keyboard 1 to enable the PIN code to be updated.Enter another PIN number and operate the registration key on the keyboard 1 as well. The password will be updated. Therefore, in order to resume business after that, the user must enter a new password.

In this way, according to the above embodiment, the leave key 3
Any key input from keyboard 1 can be invalidated by the operation of , and even if the operation is performed again, business execution will not be possible unless the PIN is entered correctly, thus reducing security. It is extremely advantageous in terms of security and crime prevention. If an incorrect password is entered several times, the entire device will be locked and an alarm will be issued. To cancel the alarm, turn on the separately provided supervisor key switch 2. Since this cannot be done without keying in a specific number, it is almost impossible for an unspecified person to use the device while the operator is away, and this reduces system security and crime prevention. It has the advantage that it can be made extremely high. Furthermore, according to the above embodiment, the PIN can be updated by turning on the responsible person key switch in the normal state and inputting a certain number, so if the PIN is known to someone else, etc. This has the advantage that it is possible to perform the above operation and change to a different PIN number, further ensuring security.

Incidentally, FIGS. 3 and 4 are a time chart and a flow chart, respectively, showing the operation of the above-described embodiment.

Effects of the Invention As is clear from the above embodiments, the present invention provides a leave key, which makes it impossible to input any keys by operating the leave key. It is configured so that there is no other way than to enter the PIN number, and if the PIN code is entered incorrectly, an alarm will be issued and the operation of the entire device will be locked, and a specific number must be entered to restart the system. This has the advantage that it is possible to completely prevent the device from being used by an unspecified person.
