Further, the child device key input device 24 has a display element 49 and an alarm element 50 corresponding to the display element 46 and the alarm element 47 of the parent device key input device 23, and when the display element 46 and the alarm element 47 operate, It is controlled by the CPU 41 of the master device key input device 23 so as to operate in parallel with this.

The monitor 22 is a television video signal from the CATV line 10.
It has a television signal receiving section 51 for receiving TVIN _O.
The television signal receiving section 51 selects one of a plurality of channel television image signals coming from the CATV line 10 by a built-in television channel circuit, and then similarly uses a built-in standard television. Three primary color signals RG having the format of a standard television system (for example, NTSC system) television signal in the decoding circuit
B1 is a cathode tube (CR
T) 54, thus displaying the reproduced image of the television video signal received on the CRT 54.

Similarly, the television signal receiving unit 51 reproduces the audio signal AUD1 from the television signal which is selected and received in the same manner.
The audio signal AUD1 is supplied to the speaker 56 through the switch circuit 55 of the sound device 58, and thereby the audio of the television video signal selected and received is reproduced.

The reception tuning operation of the television signal receiving section 51 is controlled by the control signal CON1 of the remote control circuit 57. The remote control circuit 57 has a remote control signal RM supplied from the master key input device 23.
It is controlled by T and gives a corresponding control signal CON1 to the television signal receiving section 51. At the same time, the remote control circuit 57 controls the switch circuits 53 and 55 by the control signal CON2 while controlling the television signal receiving section 51 by the control signal CON1 to output the three primary color signals RGB1. The audio signal AUD1 is supplied to the speaker 56 while being supplied to the CRT 54.

Here, when the key matrix 45 is designated and tuned to the television reception mode (that is, the "television" display mode), the master key input device 23 sends a remote control signal RMT corresponding to the CPU 41 via the input / output device 44. Then, the television signal receiving section 51 is controlled to be in the channel selection receiving state. In addition, the remote control circuit 57
When the key matrix 45 of the master key input device 23 is designated to the page image data reception mode (that is, the "management information" display mode), the switch circuits 53 and 55 are switched by the control signal CON2 to the video text data processing device 21 side. Switch operation to.

Further, the remote control circuit 57 receives the television signal by the control signals CON1 and CON2 when the key matrix 45 of the master device key input device 23 is designated in the superimpose reception mode (that is, the "screen composition" display mode). The television image signal RGB1 and the audio signal AUD1 of the unit 51 are input to the switch circuits 53 and 55. At this time, the video text data processing device 21 is operated by the master device key input device 23.
The switch circuit 53 is alternately switched by the superimpose bit SPI included in the image display signal VTX on the basis of the key input data inputted from the television display video signal RGB1 to the image display signal VTX. Display the screen where the image signal RGB2 of is superimposed.

The video text data processing device 21 has a video RAM 61 for supplying an image display signal VTX to the monitor 22 and a sound generator 62 for supplying an audio signal AUD2 to the monitor 22.

The video RAM 61 obtains an image signal RGB2 for displaying a page image on the CRT 54 and a superimpose bit SPI based on the page image data coming from the communication network 2 via the modem 35.

When the CPU 31 converts the page image data into the image display signal VTX and displays it on the CRT 54 of the monitor 22, the sound generator 62 generates a sound indicating this (for example, a click sound) under the control of the CPU 31. As a result, the user can be audibly notified of the arrival of new image display data.

In this way, the page image data transmitted from the center 3 to the terminal devices 1A, 1B, ...
The sound signal is converted into X and displayed on the CRT 54 of the monitor 22, and at the same time, an audio signal AUD2 is generated in the sound generator 62 each time page image data arrives.

The video text data processing device 21 includes a printer.
The page image data transmitted from the center 3 to the CPU 31 can be printed out and recorded by connecting a 63 and a recording device 64.

(G2) Basic data processing procedure In the above configuration, the information system is the terminal device 1A,
The center 3 creates device control data based on the request from 1B ..., and the device control data is used to control each device of the terminal devices 1A, 1B. It responds to display a screen based on a video signal.

That is, in step SP1 of FIG. 9, when the user operates a desired key using the master device key input device 23 of the terminal devices 1A, 1B ..., The CPU 41 of the master device key input device 23 operates in response to the following operation. The code data corresponding to the key operated in step SP2 is sent to the video text data processing device 21 through the input / output device 44.

At this time, the CPU 31 of the video text data processing device 21 fetches the code data from the master key input device 23 through the input / output device 37 in step SP3 and converts it into a code which can communicate with the center 3 and then in step SP4. It is determined whether or not a key for controlling the function of the video text data processing device 21 itself has been operated. If a positive result is obtained here, the CPU 31 moves to the next step SP5 and executes the processing. The processing of the video text data processing device 21 itself includes a two-screen mode, recording and reproducing page image data in the recording device 64, and printing out the data to the printer 63.

On the other hand, if a negative result is obtained in step SP4, the CPU 31 of the video text data processing device 21 moves to step SP6 and sends the key input data to the center 3 via the communication network 2.

Here, when controlling functions other than the video text data processing device 21, a request for pulling out page image data stored in the video text database 6 of the center 3, a request for inputting page image data for the entry / exit table, a dispatch center There is a vehicle dispatch request to 19, and a request to set the display mode of the monitor 22.

At this time, the host computer 4 of the center 3 receives and stores the key input data in step SP7, and then executes a process corresponding to the key input data in the next step SP8, and at the same time, responds to the request with page image data, or Communication network for device control data 2
It is sent back to the terminal device that issued the request via.

The center 3 stores the request data coming from the terminal at step SP7 each time the display mode is specified, the reception channel is specified, and the page image data to be extracted is specified from the terminal devices 1A, 1B .... By doing so, it is possible to create data for grasping the operational status of the information system.

At this time, in the terminal device, the CPU 31 of the video text data processing device 21 makes the center 3 in step SP9.
The data transmitted from the communication network 2 through the communication network 2 is received, and it is determined in the next step SP10 whether the data transmitted is the device control data.

Here, the device control data means control data for all the devices that the host computer 4 needs to control when viewed from the host computer 4 of the center 3, and the first control item is the video text data processing device 21. 2 has an item for controlling the display mode when displaying image data on the monitor 22, and a second item for controlling the master unit key input device 23 and the slave unit key input device 24. Among the control items for the master key input device 23, the items for controlling the display element 46 and the alarm element 47 included in the master key input device 23 and the items for controlling the output of the remote control signal RMT to the monitor 22. And are included.

On the other hand, when the data transmitted from the center 3 to the video text data processing device 21 is not the device control data, it becomes the page image data extracted from the video text database 6 of the center 3.

Therefore, the CPU 31 of the video text data processing device 21
When a negative result is obtained in step SP10, step SP
Moving to 11, the page image data is decoded into the image signal RGB2 in the video RAM 61, and the sound signal AUD2 is generated by driving the sound generator 62.

At this time, the monitor 22 displays the image signal at step SP12.
RGB2 is displayed on the CRT 54, and sound is generated in the speaker 56 based on the sound signal AUD2.

On the other hand, if an affirmative result is obtained in step SP10, the CPU 31 moves to step SP13 in FIG. 9 and the content of the data transmitted from the center 3 is the data for controlling the output mode of the video text data processing device 21 itself. Or not. If an affirmative result is obtained here, the CPU 31 executes the processing corresponding to the transmitted output mode control data in the video text data processing device 21 in step SP14. In this processing, the CPU 31 actually executes the program corresponding to the output mode control data transmitted from the program ROM 33.
It is executed by controlling the video RAM 61 and the sound generator 62.

On the other hand, if a negative result is obtained in step SP13, the CPU 31 proceeds to next step SP15. This step S
P15 is a step for judging whether or not the device control data transmitted from the center 3 is control data for the master key input device 23 (and the slave key input device 24), and a negative result is obtained. This means that the content of the device control data is the control data of the printer 63 or the recording device 64 provided in the video text data processing device 21, and accordingly, the CPU 31 shifts to step SP16. Printer 63,
The control operation of the recording device 64 is executed.

On the other hand, when a positive result is obtained in step SP15, this means that the content of the device control data transmitted from the center 3 is the control data for the master key input device 23, and therefore CP
The U31 proceeds to step SP17 to convert the control data into a code that can be easily processed by the CPU 41 of the master key input device 23 and transmits it to the CPU 41 of the master key input device 23.

At this time, the CPU 41 receives the transmitted control data in step SP18, and then moves to step SP19. This step SP19 is a step for judging whether or not the transmitted control data is data to be processed inside the master unit key input device 23 and the slave unit key input device 24, and the master unit key input device 23 The CPU 41 executes this judgment, and when a positive result is obtained, the CPU 41 performs processing in step SP20 based on the contents of the control data. As the processing, the master unit key input device 23 and the slave unit key input device
There is a process of driving the 24 display elements 46 and 49 and the alarm elements 47 and 50. Here, the display element 49 and the alarm element 50 of the child device key input device 24 are simultaneously driven in parallel with the display element 46 and the alarm element 47 of the parent device key input device 23 under the control of the CPU 41.

On the other hand, when a negative result is obtained in step SP19, this means that the content of the transmitted device control data is not the control data of the master device key input device 23 and the slave device key input device 24 itself. Since it means that the CPU 41 of the master device key input device 23
Move to P21 and send remote control signal RMT.

At this time, the remote control circuit 57 of the monitor 22
At the next step SP22, the remote control signal RM
TV reception signal receiving section 5 according to the content of receiving T
The control signal CON1 for 1 or the control signal CON2 for the switch circuits 53 and 55 of the display device 52 and the sound device 58 is supplied.

Thus, the remote control circuit 57 selects the channel to be received in accordance with the content of the remote control signal RMT, and thereby the switch circuits 53 and 55.
By switching to the television signal receiving section 51 side, the received video signal is displayed on the CRT 54 and sound is generated from the speaker 56. Further, the remote control circuit 57 switches the switch circuits 53 and 55 to the video text data processing device 21 side by the control signal CON2 according to the content of the remote control signal RMT, and the image from the video text data processing device 21 is displayed. The display signal VTX is displayed on the CRT 54, and a sound based on the output AUD2 of the sound generator 62 is generated from the speaker 56.

At this time, the CPU 31 of the video text data processing device 21 receives the code data in step SP49, converts the device control data contained in the received code data, and supplies it to the master device key input device 23. The CPU 41 of the master device key input device 23 receives the device control data at the next step SP50, causes the "attended" lamp 74AX (Fig. 7) to be lit and displayed, and "leaves" to indicate other leaving / leaving states. , Turn off the "absent" lamps 74BX and 74CX.

Thus, the fact that the automatic registration has been completed can be displayed on the master device key input device 23 of the terminal device, whereby the initialization process for the entry / exit table page image data is completed, and thereafter the terminal device enters a steady operation. .

The registration in the "attendance table" during this steady operation is such that when a change occurs in the attendance status, the user selects "attended", "away", "absent" switch 74A, 74B at step SP51,
This is done by operating one of the 74C (or 24A, 24B, 24C). At this time, the CPU 41 of the master device key input device 23
Moves to step SP52 and sends the corresponding key input data to the video text data processing device 21.

The CPU 31 of the video text data processing device 21 receives the key input data transmitted in step SP53, and after code conversion, sends the key input data to the center 3 in step SP54.

At this time, the host computer 4 of the center 3
After receiving and storing the key input data transmitted in SP55, in the following step SP56, the terminal device that performed the key input operation is identified based on the ID data included in the key input data, and this user is identified. After that, step SP57
Then, the code data for setting the lamp of the master key input device 23 to the operation mode is returned to the determined terminal device.

In step SP58, this code data is received by the CPU 31 of the video text data processing device 21 of the terminal device, and the device control data is code-converted and sent to the master key input device 23.

At this time, the master key input device 23 receives the device control data in step SP59, and turns on the corresponding one of the "attended", "away", and "absent" lamps 74AX, 74BX, 74CX. , Turn off the remaining lamps.

Therefore, for example, if the user who is in the seat is
When the "leaving" switch 74B is operated at, the "leaving" lamp 74BX of the master key input device 23 lights up under the control of the host computer 4 of the center 3 and other lamps (that is, "Attendant" lamp 74AX and "Absent" lamp 74CX) turn off. Thus, the user is in the center 3
Can be confirmed to have responded.

The host computer 4 of the center 3 uses the above-mentioned steps.
When a predetermined time elapses after sending the code data in SP57, in step SP60, the corresponding column (that is, the terminal that issued the request) in the "Enter / Exit table" page image data formed in the video text database 6 The data in the name field assigned to the device is updated according to the content of the key input data transmitted.

The processing steps in the above steps SP51 to SP60 are:
Every time the entry / exit input switch is operated in the master unit key input device 23 or the slave unit key input device 24, the "exit / exit table" page image data formed in the video text database 6 of the center 3 is repeated. The contents of will be updated every moment to the contents corresponding to the contents input in each terminal device. Therefore, if this "Enter / Exit" page image data is withdrawn as necessary, It is possible to read the status of officers and managers, etc., at a glance as a list format.

In addition to the above configuration, when the video text data processing device 21 of each terminal device 1A, 1B ... Is turned off,
Since the video text data processing device 21 is turned off in step SP61, the carrier cannot be sent to the center 3 in the following step SP62. At this time, the host computer 4 of the center 3 judges in step SP63 the ID code of the terminal device which has interrupted the carrier transmission, and in the following step SP64, the "entry / leaving table" page image data formed in the video text database 6 The "absent" data is automatically registered in the corresponding column (that is, the column assigned to the terminal device that is powered off).

Thus, when a large number of users of terminal devices leave the office by turning off the power of the video text data processing device 21 of the terminal device without inputting "absence" data when leaving the company, Also, the withdrawal status along with the actual situation can be left in the video text database 6.

(2) Reading the “Entry / Exit Table” The data that is accumulated momentarily in the “Exit / Exit Table” page image data of the video text database 6 of the center 3 is terminal device 1A, 1B according to the following two display modes. ......
Can be read as required.

(A) Page image display mode This display mode is a display mode in which the page image data of "entry / leaving table" is transmitted as the page image data and is displayed on the monitor 22, and is used in step SP71 of FIG.
