Abstract

PURPOSE:To monitor the state of a job which is not displayed by providing two job development memories corresponding to the display area of a CRT display device. CONSTITUTION:When window control is requested, a display management module 3 changes display of overall contents of a display development memory 51 of a primary job to display of mixture (indicated by oblique lines) of contents of a display area 51A of the memory 51 and those of a display area 52A of a display development memory 52 of a secondary job. Hereafter, a window management module 2 requests the display management module 3 to display contents of the display development memory 52 of the secondary job, thereby realizing an active window. Thus, two jobs are simultaneously operated and execution states of both jobs are recognized.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an active window control method, and particularly to an active window control method for controlling the screen of a POS system.

[Conventional technology]

In conventional POS systems, the first job is cashier work,
My secondary job was to communicate inventory data and sales data. However, since it was only possible to select either the primary job or the secondary job and display only one job on the display, it was not possible to monitor the status of the job that was not displayed.

[Problem to be solved by the invention]

As mentioned above, in such a POS system based on conventional technology, when the primary job is cash register work and the secondary job is communication work for inventory and sales data, the primary job is displayed on the display. The drawback is that it is not possible to monitor secondary jobs while performing work.

[Means to solve the problem]

The active window control method of the present invention includes a window management module that outputs window control information in accordance with key signals from a keyboard, and a memory that is controlled in accordance with the window control information from the window management module and a predetermined area of the memory. CR information on
a display management module for outputting to a T display device, two job expansion memories corresponding to the display area of the CRT display device, and the display management module outputs the output to the CRT display corresponding to the two job expansion memories. In the area of the apparatus, data from the corresponding job development memory is transferred to the CRT display device, and the contents of at least one of the job development memories are changed at predetermined time intervals.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

This embodiment includes a keyboard 1, a window management module 2, a display management module 3, a CRT display device 4, and a memory 5.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

When window control is requested or canceled by key operation (input) on the keyboard 1, the window management module 2 notifies the display management module 3 of the content.

When a window control request is made, the display management module 3 stores the display development memory 5 of the primary job until then.
1 was displayed in the entire area, now a mixture (shaded area) of the display area 51A of the display expansion memory 51 of the primary job and the display area 52A of the display expansion memory 52 of the secondary job is displayed. change. Thereafter, the window management module 2 makes it possible to realize an active window by requesting the display management module 3 to display the secondary job in the display expansion memory 52 at regular time intervals. At this time, on the display of the CRT display device 4, the data in the display area 51A of the display development memory 51 of the primary job is displayed on the primary job display section 41A, and the data in the display area 52A of the secondary job display development memory 52 is displayed.
data is displayed on the secondary job display section 42A.

When canceling window control, the display management module 3 displays a mixture of the display area 51A of the display expansion memory 51 of the primary job and the display area 52A of the display expansion memory 52 of the secondary job. In this case, the entire area of the display expansion memory 51 of the primary job is changed to be displayed on the entire area of the CRT display device 4. In addition, in such cases, most operations can be changed using software, so it is also possible to use conventional terminals.

〔Effect of the invention〕

As explained above, the present invention makes it possible to run two jobs at the same time and view the execution status of both jobs, making it easy and inexpensive to use in a system for simultaneous processing of cash register work and communication work in a POS system. Moreover, it becomes possible to operate in real time. This has the effect that it can be used to realize a new POS system.

Claims (1)

[Claims] a window management module that outputs window control information according to key signals from a keyboard; and a display management that controls a memory according to the window control information from the window management module and outputs information in a predetermined area of the memory to a CRT display device. and two job development memories corresponding to the display areas of the CRT display device, and the display management module allows areas of the CRT display device corresponding to the two job development memories to correspond to each other. An active window control method characterized in that data from the job expansion memory is transferred to the CRT display device, and the contents of at least one of the job expansion memories are changed at predetermined intervals.
