[Example 1] An example in which the present invention is applied to a POS terminal will be described below with reference to the drawings.

FIG. 2 is an external view of the POS terminal, in which a keyboard 2 is provided at the center of the front of the housing 1 for inputting the product code of the product being sold, the sales amount, etc. In addition, a display section 3 is provided at the upper front of the housing 1 to display the sales amount 9 of the keyed product, the total amount, etc., and on the side of this display section 3, the sales amount 1 A dot printer 4 is provided for printing the total amount and the like.

Further, a drawer 5 for storing cash and the like is installed on the lower surface of the housing 1. Furthermore, a power switch 6 is provided on one side of the housing 1.

FIG. 3 is a block diagram of the POS terminal, in which 10 indicates a store controller, 11 indicates a main body of the terminal, and 12 indicates a power supply section of the terminal.

In the main body 11, a CPU (central processing unit) 13 has a built-in arithmetic circuit, a memory control circuit, etc., and performs predetermined arithmetic processing according to various input signals, and also inputs fixed data such as programs via a pass line 14. A ROM (read only memory) 15 for storing data and a RAM (random access memory) 16 for storing variable data such as input data and arithmetic processing data are operated. Further, a keyboard interface 17 for inputting key signals from the keyboard 2, a display interface 18 for driving and controlling the display unit 3, a printer interface 19 for driving and controlling the dot printer 4, a drawer interface 20 for opening the drawer 5, and a transmission line 2.
A communication interface 22 that controls data communication with a store controller 22 as a higher-level model connected via a path line 14 and an input/output port 23 are connected to the CPU 13 via a path line 14 .

The input/output boat 23 is connected to a power judgment switch 24 which is interlocked with the power switch 6. When the switch 24 is opened, a high level signal of the reference voltage r+5VJ is supplied, and when the switch 24 is closed, it is grounded. and becomes low level.

On the other hand, in the power supply section 12, the power supply circuit 25 applies a predetermined voltage to each component of the main body section 11, and a fuse 27, A noise filter 28, a power switch 6, a remote power controller 29, and a transformer 30 are interposed.

The remote power controller 29 is connected to the transmission line 2
When the power supply is commanded to turn on by a remote power signal given from the store controller 10 via the store controller 10, it operates to connect the power line, and when the power supply is commanded to turn off, it operates to disconnect the power line. , and the power switch 6 are connected in parallel.

FIG. 4 is a front view showing the appearance of the display section 3. FIG. As shown in the figure, the display unit 3 includes a 16-digit dot display 31 (D1 to D16) in which each digit is a [5×7] dot.
Payment mode, registration mode.

Status display LED group 32 indicating status such as registration, error, etc.
It is composed of. In this embodiment, the status display LE corresponding to the first digit D1 of the dot display 31:
Let D32a be a display element that indicates a state in which the power is turned on by the remote power controller 29.

Thus, the CPLJ 13 in the main body 11 executes the flowchart shown in FIG. 5 when a predetermined operating voltage is applied from the power supply circuit 25. That is, first, the input/output boat 23
．． After performing processing such as clearing the RAM 16, the status of the input/output board 23 is read (power supply determining means). If the boat 23 is at a low level, the power judgment switch 24 is closed in conjunction with the turning on of the power switch 6, so it is determined that the power was turned on by the power switch 6, and a dot is displayed on the display section 3. In the first digit D1 of the container 31, “
Display OII (notification means). At this time, the status display LED group 32 is all turned off.

On the other hand, if the boat 23 is at a high level, the power judgment switch 24 is open, so it is determined that the power is turned on by the remote power controller 29, and the RPC pre-state display LED 32a on the display unit 3 is turned on. (notification means). At this time, all digits of the dot display 31 are off.

Thereafter, the process shifts to normal processing as a POS terminal. At this time, the display state of the display unit 3 changes according to the generated display data.

In this way, in the POS terminal of this embodiment,
When the power switch 6 is turned on to turn on the power, the power determination switch 24 is closed in conjunction with the power switch 6, and the input/output port 23 becomes low level. As a result, the CPU 13 determines from the state of the boat 23 (low level) that the power was turned on by the power switch 6, and the lowest digit D of the dot display 31 on the display section 3
1 is displayed as “0”.

On the other hand, when the power switch 6 is not turned on, a remote power signal that instructs the store controller 10 to turn on the power is input to the remote power controller 29, and when the power is turned on under the control of the remote power controller 29, the power judgment switch Since port 24 is open, input/output port 23 becomes high level. As a result, C
At PLJ 13, it is determined from the state (high level) of the boat 23 that the W1 power source is turned on by the remote power controller 29, and the RPC pre-state display LED 32a on the display section 3 is lit.

Therefore, according to this embodiment, it is possible to reliably distinguish whether the power is turned on by the power switch 6 or by the remote power controller 29 depending on the display state of the display unit 3. That is, the first digit D1 of the dot display 31 is “0”.
'' is displayed, it is distinguished from the power switch 6, and when the RPC pre-state display LED 32a is lit, it is distinguished from the remote power controller 29.As a result, the When the power of the POS terminal is turned on, it can be easily recognized whether it is due to forgetting to turn off the cashier or due to remote control by the store controller 10, quickly detecting forgetting to turn off W18I, and simplifying management.

Although the above embodiment shows the case where the present invention is applied to a POS terminal, it can also be applied to various types of personal computers, etc., which are connected to a higher-level model such as a host computer through a transmission line, and are equipped with a remote power controller in addition to a power switch. Needless to say, it can be applied to terminals.

[Effects of the Invention] As detailed above, according to the present invention, it is possible to easily distinguish whether the power is turned on by the power switch or by remote control from a higher-level model, and it is possible to easily distinguish whether the power is turned on by the power switch or by remote control from a higher-level model. It is possible to provide a terminal device that allows you to easily check for forgetfulness.
