Field of Industrial Application The present invention relates to a data input device, and is suitable for application to, for example, an information system adapted to provide information to a large number of terminal devices from a center as needed. .

B. Summary of the Invention The present invention is a data input device used in an information system adapted to transfer data between a plurality of terminal devices and a center, and also includes a master device input means having a CPU as a terminal device and a CPU. In addition, a slave unit input means is provided, and the data input in the slave unit input means is converted into C of the master unit input means.
By configuring the data processing using the PU, it is possible to simplify the configuration of the data input means as the information system as a whole.

C Conventional Technology As an information system of this type, conventionally, terminal devices are scattered in many departments within a company, and in-house information accumulated in the center is supplied in response to a request from each terminal device. There is proposed a structure that can be done.

D. Problem to be Solved by the Invention In the conventional information system, however, the terminal device for inputting a request to the center can effectively utilize almost all functions of the center as much as possible. It is configured to have such a function. For this reason, a central processing unit (CPU) capable of exchanging data with the center is provided in all the terminal devices.

However, when an information system becomes large in scale and an attempt is made to increase the number of terminal devices that issue requests to the center, a terminal device having a function that allows all of the functions of the center to be used as each terminal device is required. If it is used, it is inevitable that the configuration of the terminal device as a whole system becomes large.

For example, information about items that are considered necessary for the management of the company in the center can be read by a terminal device assigned to an officer in charge of the management department, a manager, etc.
When considering an information system that can transmit contact information from the terminal device side to the center by using a data transmission network installed between the center and each terminal device, for example, the terminal assigned to the president When the device is used by the president himself, it is necessary to prepare a terminal device capable of reading the grade information having the highest degree of corporate confidentiality, but at the same time, a department attached to the president (for example, General affairs), unlike other positions, also needs to have a terminal device in order to perform the business that plays a part of the business of the president.
However, it is not necessary to obtain the information of the highest grade originally assigned to the president as the terminal device to be assigned to the general affairs officer, but the president actually requested it by the input operation of the general affairs officer. It is necessary to have the center perform the same processing as the case.

The present invention has been made in consideration of the above points, and as a terminal device, a master unit input means capable of responding to the function of the center is provided, and a part of the function is performed in association with the master unit input means. When a request is issued from the child device input means by providing the child device input means, the center performs the same processing as the input data input from the parent device input means. It is intended to propose an input device that is designed to be obtained.

E Means for Solving Problems In the present invention, in order to solve the problems, a plurality of terminal devices 1A, 1B are provided to the center 3 via the communication network 2.
, And the data is transferred between the terminal device that issued the request and the center based on the request data input from each of the terminal devices 1A, 1B. All or some of the terminal devices 1A, 1B ... Have a CPU 41 and a first data input device 45 that perform data processing so that they can communicate with the center 3, and the first data input device 45 The CPU 41 has a master input unit 23 for processing the input data, and a second data input device 48 having a data input function corresponding to a part of the data input function of the first data input device 45. Then
A slave unit input unit 24 is provided for inputting the data input by the second data input device 48 to the master unit input unit 23 and processing the data by the CPU 41 so that the data can be communicated with the center 3. To do.

The data inputted from the F unit child input means 24 is taken in the parent device input means 23 and processed by the CPU 41 thereof.

Thus, the CPU 41 of the parent device input means 23, the data input from its own data input device, that is, the first data input device 45, and the second data of the child device input means 24.
Data input from the data input device 48 of
Data is processed so that it can be delivered to and from each center.

Thus, when the terminal device is viewed from the center 3, there are two data input devices 45 and 48 as data input means, but only one CPU is provided as a CPU for these two data input devices. Therefore, the configuration of the input means when viewed as the entire information system can be further simplified.

[2] Data Input Unit The master device key input device 23 and the slave device key input device 24 of FIG. 1 function as a data input unit for sending key input data to the video text data processing device 21. Have a configuration.

(1) Configuration of Data Input Section The data input section of the master key input device 23 has a key input data generation section 91 including a data processing section 40 (FIG. 3) which is a microcomputer and a data selector 90. The data processing unit 40 generates a scan signal SCN composed of 8 [bit] line signals SCN0 to SCN7, and supplies the scan signal SCN to the row lines of the key matrix 45.

When a logical "H" level voltage is supplied to the eight column lines of the key matrix 45 via the resistor 92, and the key switch 93 provided at the intersection of the column line and the row line of the key matrix 45 is closed. , When the scan signal SCN given to the row line to which the closed key switch 93 is connected is at the logic "L" level, the data of the logic "L" level is output from the column line to which the closed key switch 93 is connected. The signal is adapted to be sent out, and thus the data having the code corresponding to the closed key switch 93 is obtained from the eight column lines of the key matrix 45.

That is, as shown in FIG. 3, scan output 1, 2, ...
The bits of the logic "L" level are switched in the order of 8 at predetermined time intervals in the order of scan outputs SCN0, SCN1 ... SCN7, whereby the row line of the key matrix 45 sequentially falls to the "L" level. By
Data having a bit of logic "L" level by timing corresponding to the scanning position of the key switch 93 is transmitted from the column line of the key matrix 45.

The key input data DT11 obtained on the first to fourth column lines of the key matrix 45 is connected to the input terminals 1A to 4A of the data selector 90, and the data selector 90 outputs the data of the input terminals 1A to 4A to the output terminal 1Y. .. to 4Y, the data DT11 obtained on the first to fourth column lines of the key matrix 45 when in the selection mode is sent to the 0th to 3rd input terminals KRT0 of the data processing section 40.
~ It is designed to be supplied to KRT3.

On the other hand, the input data DT12 obtained on the fifth to eighth column lines of the key matrix 45 is connected to the fourth to seventh input terminals KRT4 to KRT7 of the data processing unit 40, whereby the key matrix 45th to 8th
The data obtained on the second column line is supplied to the input terminals KRT4 to KRT7 of the data processing unit 40.

The key switch 93 of the key matrix 45 is turned on when a key top of the switch arranged on the keyboard (FIG. 6) of the master key input device 23 is operated,
A logic "L" level data output is sent to the connected column line.

The key switch unit 48 of the child device key input device 24 has a key switch 94 which is turned on when the switches 24A to 24D arranged on the keyboard (FIG. 7) of the child device key input device 24 are operated. When one of the switches 94 is turned on, the potential of the ground line 94A is output to the logic level forming circuit 95 of the master key input device 23 through the key switch 94 which is turned on.
As. The logic level forming circuit 95 has four sets of a series circuit of a resistor 95A and a zener diode 95B connected in series between a logic “H” level power supply line and ground, and connects a data output TOUT to each connection point. , 4 bits of data DT2 to be supplied to the input terminals 1B to 4B of the data selector 90 are transmitted from the output terminal thereof.

Thus, when each key switch 94 of the key switch unit 48 is closed, the data DT2 in which the corresponding bit falls to the logic "L" level is input to the data selector 90, and the data selector 90 outputs the input terminals 1B to 4B. When connected to the 1Y to 4Y sides, the data DT2 is input to the data processing unit 40 via the data selector 90 to the 0th to 3rd input terminals KRT0 to KRT3.

Key select signal output terminal KSEL of data processing unit 40
A key select signal KSELX for switching between the logic "L" and "H" levels at a predetermined cycle is output to the data selector 90 according to the key select signal KSELX.
Performs input data selection operation. That is, when the key select signal KSELX falls to the logic "L" level, the data selector 90 connects the input terminals 1A to 4A to the output terminals 1Y to 4Y, and from this state, the key select signal KSELX is at the logic "H" level. When it rises, the input terminals 1B to 4B are connected to the output terminals 1Y to 4Y. Thus, the data DT11 obtained from the key matrix 45 of the parent device key input device 23 and the data D obtained from the key switch unit 48 of the child device key input device 24.
T2 and T2 are sequentially and alternately fetched into the data processing unit 40.

(2) Operation of the data input section In this way, the data sequentially and alternately fetched into the data processing section 40 is under the control of the CPU 41 incorporated in the data processing section 40 according to the processing procedure shown in FIG. And the key input data KDATA is output to the video text data processing device 21.

In step SP1 of FIG. 2, when the main routine enters the subroutine consisting of the processing program for the data of the master key input device 23 and the slave key input device 24, the CPU 41 of the master key input device 23 determines the key input data. After the processing other than the data processing is executed in step SP2, the process proceeds to step SP3 and it is determined whether or not there is a key input from the key matrix 45 of the master key input device 23. If there is no key operated in the key matrix 45, a negative result is obtained in step SP3, and the CPU 41 causes the next step SP3.
Go to 4.

In step SP4, the CPU 41 determines whether or not a key input has been made from the key switch unit 48 of the child device key input device 24, and when a negative result is obtained, the CPU 41
Returns to step SP2 described above and repeatedly executes processing of other data.

The determination of step SP3 and step SP4 is made by the CPU4.
1 is executed by controlling the data input section as follows.

First, when the CPU 41 proceeds to step SP3, it lowers the key select signal KSELX to the logic "L" level and switches the data selector 90 to the input terminals 1A to 4A side. At this time, the data selector 90 uses the key matrix 4
The data DT11 output from the data processor 5 is input to the input terminals KRT0 to KRT3 of the data processing unit 40. On the other hand, other data DT12 of the key matrix 45 is directly input terminal KRT.
Since the data is input to 4-KRT7, it is possible to obtain a state in which the 8-bit return key input data KIN data output from the key matrix 45 is input to the data processing unit 40.

In this state, the CPU 41 causes the scan output SCN0 to
It is determined whether or not all the bits of the key input data signal, which are brought down to the logic "L" level for a predetermined time all at once and returned to the input terminals KRT0 to KRT7, have the logic "L" level. To do.

As a result, if all the bits are logic "H", this means that there is no operation by the key switch 93 of the key matrix 45, and accordingly, the CPU 41 causes the master key input device to operate. It can be determined that 23 has no key input.

On the other hand, one of the input terminals KRT0 to KRT7
If data of logical "L" level is obtained, it can be determined that there is an operated key in the key matrix 45.

When the CPU 41 enters step SP4, it switches the key select signal KSELX to the logic "H" level. In response to this, the data selector 90 switches to a state in which the input terminals 1B to 4B are connected to the output terminals 1Y to 4Y. In this state, the CPU 41 determines that the input terminals KRT0 to KRT
It is determined whether or not 3 has a bit of logic "L" level. As a result, if there is no logic "L" level bit, it can be determined that the key switch 94 of the child device key input device 24 has not operated the switch, and thus the CPU 41 obtains a negative result in step SP4.

On the other hand, if a positive result is obtained in step SP3, the CPU 41 moves to step SP5 and goes to SCN0 to SCN0.
The bit output S is sent to the SCN 7 as described above with reference to FIG.
CN0, SCN1 ... Sends a scan signal SCN for switching SCN7 to the logic "L" level in sequence, and after receiving the return key input data signal KIN returned to the input terminals KRT0 to KRT7, the next step Move to SP6. This step SP6 is a step for judging whether or not the same key is repeatedly pushed multiple times. If it is a multiple push, a positive result is obtained and the process proceeds to step SP7 to invalidate the master unit key input. After performing the processing, the process proceeds to the above-mentioned step SP4. On the other hand, if a negative result is obtained in step SP6, the CPU 41 moves to step SP8 and sends the key input data KDATA corresponding to the return key input data signal KIN, which is sent to the video text data processing device 21, and then to step SP4. Move.

Thus, when there is an operated key in the key matrix 45 of the master key input device 23, the CPU 41 sends the key input data KDATA to the video text data processing device 21 only when this key is not the multiple press.

Further, the CPU 41 sends the data D output from the key switch 48 of the child device key input device 24 in step SP4.
After T2 is fetched in step SP9, the process proceeds to the next step SP10. This step SP10 is a step for judging whether or not the key operated in the same manner as described above with respect to the above-mentioned step SP6 is a multi-press, and when it is judged that the key is a multi-press, the CPU 41 proceeds to the next step. After moving to SP11 and performing data processing for invalidating the key input data, the process returns to step SP2.

On the other hand, when a negative result is obtained in step SP10, the CPU 41 moves to step SP12 and takes the data DT2 taken into the data processing unit 40 via the data selector 90 into the video text data processing device 21 as the key input data KDATA. Send out.

Here, the key switches that can input data in the child device key input device 24 are the "present" switch 24A and the "away" switch.
A switch 24B, a "absent" switch 24C, and a "distributed" switch 24D are selected. These switches are arranged on the master key input device 23, as is apparent from FIGS. 6 and 7. Part of "switch" 74A, "seated" switch 74B,
This corresponds to the "absent" switch 74C and the "distributed" switch 76. This is the main unit key input device 23
Means that the handset device key input device 24 has a part of the functions of the input data that can be input by. Thus, by using the master unit key input device 23, the "present" switch 74
A, "Away" switch 74B, "Absent" switch 74
By operating the C and "distribute" switches 76, the corresponding key input data can be transmitted to the video text data processing device 21, and at the same time, the slave device key input device 2
Even if the "attended" switch 24A, the "leaved" switch 24B, the "absent" switch 24C, and the "distributed" switch 72D provided in No. 4 are operated, the corresponding key input data is similarly converted to the video text data processing device 21. Can be sent to.

Here, particular attention should be paid to the CPU 4 of the data processing unit 40.
1 is a key matrix 4 in which key input data DT2 input from the key switch unit 48 of the child device key input device 24 is input.
That is, the key input data DT11 and DT12 input from the step 5 are processed as separate input data.

As a result, the CPU 41 executes the processing of the key input data to be input to the parent device key input device 23, which is the original function, and the child device key input device 2 provided in association therewith.
