Abstract

PURPOSE:To connect plural data input devices to a terminal controller and to realize the simultaneous input operations of plural operators by adding a buffer memory, an interruption request signal generating circuit, and a data switching circuit to each data input device. CONSTITUTION:Each of data input devices 2a - 2n contains a buffer memory 23, an interruption request generating circuit 24, and a data switching circuit 25. The operators use the devices 2a - 2n and perform no transfer of data to a terminal controller 1 in a data input mode to store data in the memories 23. The circuit 24 functions to keep the interruption request signal in an OFF state while the operator is inputting data. The circuit 25 stores data into the memory 23. The interruption request signal is turned ON when the data are transferred to the controller 1, and the circuit 25 validate the transfer of data carried out to the controller 1 from the memory 23. Thus it is possible to connect the devices 2a - 2n to the controller 1 and to enable plural operator use these devices 2a - 2n at one time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data input device connected to a terminal control device.

[Conventional technology]

Conventional data input devices consist of function keys and data keys, and data entered by an operator from the data input device is immediately transferred to the terminal control device, where input processing is performed while checking the data on the display. Ta. Furthermore, only one data input device was connected to the terminal control device, and while one operator was using the data input device, other operators were unable to perform input processing. Related to this species are Jikai■862-
140,123 are listed.

[Problem to be solved by the invention]

In the conventional technology described above, data input from a data input device is transferred to a memory within a terminal control device and displayed on a display. The operator performs input processing while checking the data displayed on the display. Therefore, while the data input device is in use, the terminal control device is occupied and cannot be used by other operators, resulting in a poor input processing rate.

The purpose of the present invention is to store input data in a buffer memory in a data input device, and after manual processing is completed, issue an interrupt request signal from the data input device, enable connection with a terminal control device, and store input data in a buffer memory. from there to the memory in the terminal control device. Thereby, it is an object of the present invention to provide a data manpower device in which a plurality of operators can perform input operations at the same time without occupying the terminal control device during input operations by the operators.

[Means for Solving Problems] An object of the present invention is to provide a buffer memory, an interrupt request generation circuit, and a data switching circuit in a data input device, so that when an operator uses the data input device and is inputting data, the terminal control device The data is not transferred to (does not occupy), but is stored in the buffer memory. This is achieved by issuing an interrupt request signal to the terminal control device after the data input operation is completed by the circuit described above, and occupying the buffer memory only when data is transferred.

[Effect]

The interrupt request generation circuit keeps the interrupt request signal in the OFF state while the operator is inputting data, and the data switching circuit stores the data in the buffer memory. When data is to be transferred to the terminal control device, the 5 request signal is turned on, and the data switching circuit enables data transfer from the memory to the terminal control device. This allows multiple data input devices to be connected and multiple operators to use the data input devices at the same time.

Consists of a buffer memory 23, an interrupt request generation circuit 24, and a data switching circuit 25, connected to the terminal control device 1 by a data bus.When an operator inputs data using the terminal system, the data is displayed on the display device. In the conventional method, one operator uses the data input device to input data by pressing a key switch according to the guidance provided, and the input data is stored in the main memory in the terminal control device and displayed on the display device. During this time, other operators were unable to perform input operations, reducing the efficiency of input processing.

When the input operation is finished, the operator turns on the interrupt request signal generation circuit 24, and sends the interrupt request signal A to the data human-powered device adapter 15. Those who send it to,
Data is read from the buffer memory 23 and continuously transferred to the data input device adapter 15 via the data switching circuit 25 and the data bus B. The data device adapter 15 recognizes the interrupt request signal from which data input device fl and stores it in the main memory 12 and displays it on the display device 3. - When the data from the small input device to the terminal control device is finished, the interrupt request generation circuit is turned off.
