Description

[Detailed explanation of the idea]

The present invention relates to a status display device in which setting information of the device is inserted when displaying a test display on the status display device. Conventionally, transaction information systems installed in stores such as department stores and supermarkets have multiple transaction terminals (POS) 1 installed in the store, as shown in the system diagram in Figure 1, and a terminal installed in a central processing room. Processing control device 4
It is connected in a mozuru style via joint box (JB) 2. With this configuration, the POS program data stored in the floppy recorder 3 is initial program loaded into the POS 1 in response to a command from the terminal processing control device 4. In this case, a status display device such as a portable cassette loader 5 is usually used as an auxiliary device in case the floppy recorder 3 goes down for some reason. That is, the cassette loader 5 is connected to the J.B. 2, prepares in advance a cassette in which program data to be loaded into each POS 1 is recorded, and sequentially loads the contents. In order to monitor the operating state in this case, a display that indicates the type of fault with a three-digit code when a fault occurs, and five guide lamps that indicate the status of each part including an alarm are used in conjunction with the display. The number of operation buttons is limited to the minimum necessary to make the device smaller and lighter. In such a status display device, the reliability of the display that displays the details of the fault is most important, so the display function is tested before the loading operation. This test display follows the test program.

[Table] The following 15 is an indicator light indicating that J・B and POS are in operation. Reference numeral 16 indicates two operation buttons, which are used for start/stop (ST/SP) and clear alarm release (CL). 17 is
A switch 18 is used to set group numbers 1 to 4 of the POS program, and a switch 18 is used to set the mode. The mode switch 18 sets whether to perform initial program loading (IPL) of the POS using a cassette, recording (REC) by transferring data from the floppy recorder 3, or testing the display function before loading (TEST) as described above. It is something to do. The status display device has the above-described configuration and performs an auxiliary function for the terminal processing control device 4, but is characterized by reducing the number of operation buttons as much as possible for miniaturization and omitting input means such as a numeric keypad. On the other hand, an inconvenient problem has arisen. That is, although the device number, polling number, etc. set in this status display device should have been set in advance in the ROM or the like within the device, this cannot be confirmed.
Furthermore, it is not possible to confirm whether the group numbers (1 to 4), which are numbered for each similar POS program, are set in good contact. If you have a printer or numeric keypad, it would be easy to check these things, but this status display device does not have this method at all. An object of the present invention is to provide a simple display device that does not have a numeric keypad or the like and allows confirmation of setting information and information from a setting switch on a status display device as an auxiliary device. In order to achieve the above object, the status display device of the present invention includes a display register that stores status data related to the processing of the processing device, and a display register that reads the status data from the register according to the processing of the processing device and displays the status data. A status display device comprising a display device and a test switch, the pre-processing test switch repeatedly displaying predetermined status data from a memory in a predetermined order on the display device, the status setting switch configured to externally set the status. , a test display memory that stores setting information according to the state set by the state setting switch, and data stored in the display device by scanning and reading the display register and test display memory in a predetermined order. and a means for supplying the test display, and the display function is tested by inserting and displaying the setting information stored in the test display memory in a predetermined order into the test display that is repeated in the predetermined order. be. FIG. 3 is an explanatory diagram showing the configuration of an embodiment of the present invention. This figure shows the main parts of the cassette loader 5, and the configuration of the display operation panel surface is the same as that of FIG. 2, but the internal configuration is slightly different. The display 14, group number switch 17, and mode switch 18 shown in this figure are the same as those with the same numbers on the panel in FIG. In the same figure, the fixed memory (ROM) 23 has 3
Data area 23 ₁ to (000) to (999) with the same number
23 ₁₀ and device number (DA) data area 23 ₁₁
and non-volatile memory (RAM) 24.
A data area _{241 for a group number (GNO) for specifying a POS program is provided in the data area 241} , into which the number set by the group number switch 17 is written via the decoder 25. A multiplexer 22 having a ring counter uses the contents of each of these areas as an address counter, and starts operation when the mode switch 18 is set to test.
Cyclic switching is performed in the order of 23 ₁ →23 ₁₁ , 24 ₁ , the contents of each area are stored in the display register 21, and the contents are sequentially displayed on the display 14. As explained above, according to the present invention, for a status display device that is an auxiliary device that does not have a printer or a numeric keypad, the status display device can be used to display a cycle of the display for displaying the status related to the processing. By inserting the setting information, it is possible to check the display function and confirm the setting information at the same time before operation. This makes it possible to prevent errors and the like that conventionally occur because these setting information are not confirmed.
