DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings. POS according to this embodiment
The security device of the terminal has a schematic circuit configuration as shown in FIG. 1, and a plurality of (three) POS terminals 2, 10, and 11 are connected to the POS main device 1 and input from each. A predetermined POS is constituted by the data to be obtained. The POS terminal 2 is provided with a CPU 3 for controlling the operation of the entire device in a complex manner. The ROM 3 stores a predetermined operation program, and various master data (product master, keyboard master, etc.). R used for temporary storage of calculation and display data
AM5 is connected.

A keyboard 6 is provided for inputting the name and number of sales merchandise. One operation key corresponds to one merchandise, a merchandise name is input by code input, and a merchandise name is read by bar code reading. Is configured to be input. The display device 7 is a CPU.
3 so that a product name, a quantity, an amount, and the like can be displayed thereon.

An alarm 8 and a time setting unit 9 are connected to the CPU 3. The time setting unit 9 constitutes a part of a “detection unit” that outputs a detection signal when the operation of the data input unit by the keyboard 6 or the like is interrupted.
Is set in advance, and the alarm device 8 constitutes "warning means" for giving a warning based on the detection signal when the detection signal is output from the detection means.

Also, when the detection signal output from the "detection means" is input to the CPU 3, the "restriction means" for restricting the input operation with the keyboard 6 or the like is executed so that the CPU 3 is executed by the initiative operation. Be composed.

The POS terminal 10 and the POS terminal 11 are configured similarly to the POS terminal 2 configured as described above.
These cooperative operations include the POS terminals 2, 10, 1
Each of the terminals is provided with a function that, when any one of the operations is restricted, the other terminals can confirm that the operation is restricted.

Therefore, when the operation is started as shown in the flowchart of FIG.
Processing of data input by keyboard 6 etc. (operation)
It is determined whether or not is performed. If No, the process proceeds to the next step S2, the counter of the interval (timer) in which the process (operation) is not performed is increased, and the process proceeds to the next step S3. It is determined by the time setting unit 9 whether the magnitude relationship between the preset time T and the measurement time t is T> t, and in the case of Yes, the next step S4
Then, an alarm by the alarm 8 is given by a buzzer sound or the like. At the same time, the POS terminal 10 and the PO
Also in the S terminal 11, it can be confirmed that an alarm is issued to the POS terminal 2.

When an alarm is issued in step S4, the process immediately proceeds to step S5 to limit the operation. This restriction is specifically as follows.

That is, when the operator temporarily interrupts the input operation to confirm the product during the input operation using the keyboard 6 of the POS terminal 2 and leaves the place, the operator does not have to input any more. Time measurement is started, and the operation is restricted when the time exceeds the time T set in the time setting unit 9, so that it is impossible for a person other than the operator who is permitted to perform the operation to perform the operation. In this way, it is possible to prevent improper input, and it is possible to prevent fraud such as intentionally not entering a sales product or increasing the deposit amount.

When a cash drawer is attached to the POS terminal 2, the drawer can be completely prevented from being opened, and the worst situation such as theft can be prevented. Can be.

Returning to FIG. 2, if the determination in step S1 is Yes, that is, if an input has been made using the keyboard 6 or the like, the timer used in step S2 is reset and a series of operations is terminated. (Step S
6). If No in step S3, the input operation by the operator is within the set time T, in other words, the input operation is normally performed, and thus a series of operations is ended.

Note that the security device of the POS terminal according to the present embodiment employs a "detection means" so as to limit operation for preventing fraud if an input operation is not performed continuously during a predetermined time. Although it is configured, the detecting means may be configured to output a detection signal when an operator is not present in a predetermined area including a place where the POS terminal is installed.

Further, when the operation is restricted by the detecting means and the restriction is eliminated, a more complete POS system can be constructed by requesting the operator to input a security such as a personal identification number. .
