Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a POS device with a monitor function having a function of monitoring commands and data exchanged between an accessory device connected to the POS device and the POS device body. Is.

[0002]

2. Description of the Related Art A conventional POS device has a C
In many cases, a PU (central processing unit) and a main memory are provided, and various necessary auxiliary devices such as a handheld terminal, a modem, and a card reader are externally connected. The CPU of the main body is
It operates according to a program on the main memory, outputs a command from the POS device main body, operates a corresponding accessory device, and transmits and receives data. When debugging a program of a POS device and when a failure occurs, an external measuring device such as a monitor is connected to a predetermined terminal and a signal is monitored to check a command or data to find a cause of a bug or other failure. Taking the method.

[0003]

However, when debugging or when a failure occurs in the POS device, a measuring instrument such as a monitor is connected to investigate the cause of the error or failure.
There was a problem in that it was necessary to carry equipment such as measuring instruments to the place where the equipment was installed for carrying out the survey, and the work was very large and troublesome.

The present invention has been made in view of the above points, and eliminates the above problems and eliminates the need to carry a measuring instrument such as a monitor with a monitor function incorporated in the main body of the POS device. -To provide a POS device with functions.

[0005]

In order to solve the above problems, according to the present invention, as shown in FIGS. 1 and 2, a main memory 1-2 of a POS device 1 has a mode switching unit 1-2-3 and a monitor. A display processing unit 1-2-4 is provided to switch the mode to the monitor mode by the monitor key-1-11 at the time of debugging and at the time of failure occurrence. The monitor function is realized by temporarily storing the data in the main memory 1-2 of the POS device and outputting it to the display device 1-3 or the printing device 1-5 through the monitor display processing unit 1-2-4. Characterize.

[0006]

In the present invention, since the commands and data transmitted and received between the POS device main body and the accessory device can be easily confirmed on the screen of the display device 1-3 of the POS device 1, it is possible to know what state each other has. This makes it easy to debug the program because you can see at a glance if it is running in. Further, in the failure investigation at the place where the POS device 1 is installed, the work efficiency can be improved without carrying a measuring instrument such as a monitor as in the conventional case.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows an example of the configuration of a POS device with a monitor function of the present invention. As shown in the figure, this device is
It is composed of an S device body 1, a handheld terminal 2, a card reader 3, and a modem 4. The POS device body 1 includes a CPU 1-1, a main memory 1-2, a display device 1-3, and a key.
Board input device 1-4, printing device 1-5, interfaces 1-6, 1-7, 1-8, 1-9, 1-10, monitor key-1-11, bus 1 -12.

Handheld terminal 2, card reader 3,
Input / output signals from the auxiliary equipment of the modem 4 pass through the respective interfaces 1-8, 1-9, 1-10 and the main memory 1-2.
Is processed by the CPU 1-1.

FIG. 2 is an example of a functional block diagram of a POS device with a monitor function according to the present invention. A command processing unit 1-2-1, a data processing unit 1-2 are provided on the main memory 1-2.
2, mode switching unit 1-2-3, monitor display processing unit 1-2
-4 and the program of the device switching processing unit 1-2-5 are prepared.

It will be described with reference to FIG. Commands and data input from the keyboard input device 1-4 are processed by the command processing unit 1-2-1 and the data processing unit 1-2-2, and the mode switching processing unit 1 is processed. -2-3 in the normal mode and output to the corresponding accessory device through the device switching unit 1-2-5. That is, normally, the data between the POS device 1 and the attached device is not displayed on the screen of the display device 1-3.

When debugging or a failure occurs, the monitor key-1-11 on the POS device 1 is pressed to switch the mode switching section 1-2-3 to the monitor mode, and thereafter, transmission / reception with the auxiliary device is performed. The command and data are processed by the monitor display processing unit 1-2-4 and displayed on the screen of the display device 1-3 or printed on the printing device 1-5. The monitor mode is released by pressing the monitor key-1-11 again.

[0012]

As described in detail above, according to the present invention, the following effects are expected. The command and data transmitted / received between the POS device main body and the attached device are P
Since it can be easily confirmed on the screen of the display device of the OS device,
It makes it easy to debug the programs by clearly seeing how each other is operating. See also POS
Monitors the same as before even when investigating failures at equipment installation locations.
It is possible to improve work efficiency without having to carry measuring instruments such as.
