Abstract

PURPOSE:To efficiently perform the same job by alloting a portion of the job to plural persons in charge by using other terminal devices under the control of the same terminal control device as a main terminal device as a sub-terminal device for a self terminal device at an arbitrary point of time. CONSTITUTION:The sub-terminal device address that terminal devices 106, 107 other than a terminal device 105 are used as sub-terminal devices is inputted for a terminal control device 101 from a main terminal device. The terminal control device 101 registers the main terminal device and sub-terminal device address in a terminal device connection control table 103. Next, the access right flag corresponding to the main terminal device address is set to '1' and the access right flag corresponding to other terminal device address is set to '0'. When an access request for a central processing unit 108 from the terminal device 106, 107 exists, a terminal device address whose access right flag corresponded to a registered terminal address becomes '1' is retrieved and an access to the central processing unit 108 is performed from a terminal device having the terminal device address.

2. Description of the Related Art A conventional terminal control device is disclosed in Japanese Patent Laid-Open No. 62-8.
As described in Japanese Patent No. 9129, the display data of the main terminal device can be displayed on the sub terminal device in a state where the main terminal device and the sub terminal device are fixed in advance.

[0003]

In the above prior art, when the sub-terminal device user only refers to the screen data transferred from the main terminal device and contacts the host computer to correct the data, etc. There is no consideration for accessing the host computer from the terminal device,
There is a problem that only the main terminal device user who has the access right to the host computer can correct the data. The present invention has been made in order to solve the above-mentioned drawbacks inherent in the prior art. Therefore, an object of the present invention is to provide a terminal device user who is under the control of the terminal control device in a TSS or a network system. , To define a self-terminal device as a main terminal device and another terminal device as a sub-terminal device at any time so that a plurality of users can share one task.

[0004]

In order to achieve the above object, the terminal control device of the present invention controls its own terminal device to be the main terminal device at the same terminal control at the request of the terminal device user under the control of the control device. By defining another terminal device under device control as a sub terminal device, it is possible to transfer screen data from the main terminal device to any sub terminal device. Further, by using the access right of the main terminal device for the access from the sub terminal device to the host computer, the work can be efficiently performed.

[0005]

The terminal control device of the present invention allows the terminal device under control of the terminal control device to be the main terminal device and the other terminal device under control of the same terminal control device at any time according to a request from the user. By making it usable as a sub terminal device,
The screen data is transferred to the sub terminal device and the host computer is accessed from the sub terminal device. As a result, the same task can be shared by a plurality of persons in charge and efficiently performed.

FIG. 3, FIG. 4 and FIG. 5 are flowcharts showing the operation of the present invention.

The terminal control device (101) includes a terminal device connection control unit (102) and a screen data control unit (104), and the terminal devices (105 to 107) and the central processing unit (10).
8). Terminal device connection control unit (102)
Has a terminal device connection control table (103).

The terminal device connection control table (103)
The configuration will be described in detail with reference to FIG. The terminal device connection control table (103) has an access right flag (20) indicating whether or not it has the access right to the address (201) of the terminal device which has the main / sub relationship and the central processing unit (108).
2) and.

A method of creating the terminal device connection control table (103) will be described with reference to FIG.

The terminal device (105) currently in use indicates that the user uses the other terminal device (106, 107) as a sub-terminal device. The sub-terminal device address is given to the terminal control device (101) from the main terminal device. Input (302). The terminal control device (101) registers the main terminal device address and the sub terminal device address in the terminal address registration unit (201) of the terminal device connection control table (103). Next, the access right flag (202) corresponding to the main terminal device address is set to "1", and the access right flags (202) corresponding to the other terminal device addresses are set to "0" (305).

A method of accessing the central processing unit (108) from the sub terminal device will be described with reference to FIG. When there is an access request to the central processing unit (108) from any of the terminal units (106, 107) being used as the sub-terminal unit (501), the terminal unit address registered in the terminal unit connection control table (103). A terminal device address whose access right flag (202) corresponding to (201) is "1" is searched for (503), and a terminal device having the terminal device address accesses the central processing unit (108) (504). ).

A method of transferring screen data from the main terminal device to the sub terminal device will be described with reference to FIG. When there is a screen data transfer request from the main terminal device currently having the access right to the central processing unit (108) to the sub terminal device (40
1), the terminal control device (101) refers to the terminal device control table (103) (402), and the screen data being displayed on the main terminal device having the access right flag “1” has the access right flag “0”. Search all sub-terminals (40
In step 4), the data is transferred to all sub terminals (403).
