BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer training device used for group training of computers in elementary schools, junior high schools, universities, and vocational schools.

[0002]

2. Description of the Related Art When teaching computer equipment,
A large number of child terminal devices corresponding to each student are placed in the classroom, and the parent terminal is placed for the teacher, and each student operates the child terminals according to the instruction from the teacher who operates the parent machine. There are many collective lessons. In such a collective learning device, a data transmission circuit is installed between the master unit in charge of the teacher and each slave unit in charge of each student, and the data transmission circuit is installed corresponding to the teacher's operation performed in the master unit. The image information instructed by the master computer is transmitted to the slave terminals, and the C information is installed in each slave.
The image is displayed on a display device such as an RT.

In such a training apparatus, the transmission method of the image information between the master and the slave is a computer network (LAN) which is digital transmission, or a unidirectional transmission (teacher → student) which is analog transmission, And full-duplex transmission (teacher → student, student → teacher) is used.

FIG. 5 shows an example of a conventional teaching device using a LAN, which is a computer of the teacher side master terminal device 11.
The output signal from 111 is sent to the student side terminal group via LAN12.
It is supposed to be transmitted to 13
Each of the slave terminal devices 131 to 13n of the computer 131
Make sure that the input is from 1 to 131n. Then, with respect to the master terminal device 11 and the slave terminal devices 1321 to 132n, the displays 112 and 1322 to 1322 to 132n which are CRTs for image display, respectively.
132n are provided.

That is, the image data can be transmitted and received by using the LAN 12, but when such a LAN 12 is used, the image data is digitized and transmitted. Because there is
The display screens of the displays 1321 to 132n cannot be switched instantaneously. In addition, since knowledge of communication software and the like is required, the number of people who use this training device will be limited, and the system will be expensive.

FIG. 6 shows an example of unidirectional transmission between a teacher and a student.
The output image information from the 111 is distributed to the distributor 113 and 141 to 14n.
To be connected to each of the slave terminal devices 131 to 13n. Then, in each of the slave terminal devices 131 to 13n, the transmission information is transmitted from the master side to the compensator 133 (hereinafter,
Terminal device 131 is shown as representative) and this compensator
The output from 133 is provided via multiplexer 134 to computers 1311-131n and to displays 1321-132n.

With this configuration, the teacher's display screen can be instantly displayed on the student's display. However, the teacher cannot display the display screen of any student on the screen of the display 112 on the teacher side. Therefore, when instructing each student individually, each student's terminal must be circulated, and distributors 141 to 14n are installed corresponding to each student side terminal device 131 to 13n. Therefore, a large amount of switch mechanism and coaxial cables are required.

FIG. 7 shows an example in the case of full-duplex transmission, in which the main controller which constitutes the master terminal device 11 is installed, and in the terminal group 13 on the student side, the terminal corresponding to each student. The devices 131 to 13n are divided into a plurality of groups, and the group controllers 161 to 16m are set corresponding to the respective groups. A coaxial cable is connected from each of the group controllers 161 to 16m to the slave terminal devices 131 to 13n of the corresponding group.

Here, in the main controller,
An operation panel 114 is provided together with a parent computer 111 and a display 112, and an output from the computer 111 is distributed to each group controller 161 to 16m via a distributor 113. And each group controller 161-16
The computer image information from m 2 is input to the distributor 116 via the compensators 1151 to 115m and supplied to the display 112. The operation signal of the operation panel 114 is supplied to the controller 117, and the controller 117 controls the distributor 116.

Each of the group controllers 161 to 16m is provided with a compensator 1611 to which output image information from the main controller is supplied, as represented by the controller 161, and input image information from this compensator 1611 is sent to a distributor 1612. It is supplied to the child device terminal devices 131 to 13n via the device. Further, the computer image information on the slave side is output from the multiplexer 1613 and supplied to the compensators 1151 to 115m of the main controller.

Further, each of the slave terminal devices 131 to 13n is provided with a computer 1311 and a display 1321 as represented by the device 131, and the image information from the group controller 161 is input to the multiplexer 1331 and the display 1321 is displayed. To be displayed. The output from the computer 1311 is output via the distributor 1341 and is sent to the multiplexer 1613 of the group controller 161.
Is input to the main controller of the master terminal device 11 via.

In the apparatus of such a system, since the two-way transmission enables the teacher and the student to switch the display screens instantly, the display can be doubled as compared with the case of the unidirectional transmission. This requires a component device and a coaxial cable, which results in an expensive and complicated structure and makes the installation work considerably complicated.
