Abstract

PURPOSE:To use an education supporting system even when a master is absent by sending master picture information to a system bus, and receiving the master picture information on the system bus without interposing the master by designating a picture switching mode at a booth side. CONSTITUTION:When the picture switching mode is set by operating a picture change-over switch 64 at a booth 32, a control part 61 in a control panel 41 fetches data on an information bus 33a via an interface 62, and projects it on a monitor 40 as monitor information. When the switch 64 is operated again, the data on the bus 33a is separated from the booth 32, and its own picture information is projected on the monitor 40 at the booth 32. Meanwhile, the information on the bus 33a can be received at the booth 32 side by operating a picture reading switch 54 without interposing the master 31, and a master picture can be selected arbitrarily by the panel operation of the booth. In such a way, the system can be effectively used even when the amster is absent.

Description

[Detailed Description of the Invention] CObject of the Invention J (Field of Industrial Application) The present invention relates to a word processing network system in which a plurality of word processors (hereinafter referred to as word processors) are connected by cables, and in particular, a word processor for teachers and a word processor for students. The present invention relates to an educational support system that supports group education by connecting a computer word processor, and a master device used in the system.

(Prior art) With the recent spread of Japanese word processors (word processors), word processors have been introduced in school education as well, and now there are educational support systems that connect word processors for teachers and word processors for students. is being developed. This educational support system is a system that supports group education by connecting a teacher's word processor and a student's word processor with a cable to form a word processor network, and transmitting and receiving images and audio between the teacher and students.

Figure 5 shows a conceptual diagram of this educational support system.

For exchanging information between teachers and students, use word processor 11 for teachers.
This is done through the master operation panel 12 connected to the student's word processor 13 and the booth operation panel 14 connected to the student word processor 13. In this case, the entire device used by the teacher is called the master. Additionally, all equipment used by students is called a booth.

In an educational support system, multiple booths are connected to a single master. That is, as shown in FIG. 6, cables are laid in a trunk line (bus) manner, and a maximum of eight trunk lines, for example, are connected to the master, and a maximum of eight booths, for example, are connected to one trunk line.

By the way, in the educational support system configured in this manner, as a means for the master to transmit screen information to the booth, there is a lecture mode in which master screen information is sequentially transmitted to the booth. This is achieved by operating the master operation panel each time. At this time, on the booth side that has received the screen information from the master, the self-screen is erased and the master screen is projected on the monitor instead. Therefore, if the booth side wants to view the self-view information, it is necessary to perform operations such as calling the master and asking it to terminate transmission.

In this way, conventionally, all exchanges of screen information between the master and the booth were managed by the master. That is, the master controlled the gate between the booth and the system bus, and caused the booth to receive information on the bus. For this reason, when the master (teacher) is absent, this system cannot function at all, and for example, it is not possible to conduct self-study classes that can be seen in regular school education, resulting in the problem that the master's constant presence is required. .

In addition, as shown in FIG. 7, the operation panel main body 2 on the master side
A plurality of booth selection switches 22a s 22b % 22c . . . for selecting a booth are arranged on the top of the booth selection switch 1.
It is electrically connected to any booth among the plurality of booths through b, 22C, and so on.

By the way, normally this kind of booth selection switch 22a
s 22b s 22c =-, for example, A1, B1
Only the physical numbers indicating the switch arrangement are given. For this reason, conventionally, the booth selection switch 22a122b
, 22c, . . . , it is necessary to refer to a list listing the switch numbers and student names, which poses problems such as the time it takes to select a booth.

(Problem to be solved by the invention) As mentioned above, 1. Conventionally, there was a drawback that the booth could not freely obtain the master screen. Furthermore, when selecting a booth on the master side, a list containing switch numbers and student names is required, which has the drawback of taking time.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide an educational support system that can optionally obtain a master screen by operating a panel on the booth side.

Another object of the present invention is to provide a master device used in the system that allows the master side to easily select a booth without requiring a list.

[Structure of the Invention] (Means and Effects for Solving the Problems) In other words, the educational support system according to the present invention allows the exchange of screen information between the master and the booth connected via the system bus to be performed using the operations that the master has. In an educational support system that uses a panel and an operation panel included in a booth, the master side specifies the screen viewing mode and sends master screen information to the system bus, the booth side specifies the screen switching mode, and the system Master screen information sent to the bus is received without intervention from the master.

With this configuration, the gate between the booth and the system bus, which normally depends on the control of the master, can be separated from the control of the master, so the master screen can be obtained optionally by panel operation on the booth side. This system can be used even when the master is not present.

Further, the master device used in the educational support system according to the present invention is provided with a sheet in which input targets for the plurality of booth selection switches provided on the operation panel body are written in correspondence with the plurality of booth selection switches provided on the main body of the operation panel. be.

If you use a sheet with this kind of configuration, you can understand the input target of the switch through the sheet, so
without the need for a list of switch numbers and student groups.
You can select the desired booth in a short time.

(Example) Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of the educational support system of the same embodiment. The master 31 and the booth 32 are connected via a system bus 33. System Has33 is
It consists of an information bus 33a and a control bus 33b. The information bus 33a is a bus for exchanging information such as video signals for projecting monitor images, vertical/horizontal signals, etc. between the master 31 and the booth 32. The control bus 33b is a bus for controlling information transferred through the information bus Baa.

The master 31 indicates all the equipment used by the teacher in the educational support system, including a word processor 34, a keyboard (KB) 35, and a monitor (CR).
T) It has a general word processor consisting of 3B and an operation panel 37 connected to this word processor.

The operation panel 37 is an operation device on the master 31 side when image information and audio are exchanged between the master 31 and the booth 32. As shown in FIG. 2, this operation panel 37 includes a control section 51. Interface (IF) 52, I10
It has a port 53 and a screen viewing switch 54.

The control unit 51 has a function of controlling the booth 32. The interface 52 connects the word processor main body 34 on the master 31 side to the system bus 33 configuring the word processor network. The I10 boat 53 performs input control of various switches provided on a master operation panel (not shown), including the screen viewing switch 54. The screen viewing switch 54 is a switch for specifying a screen viewing mode and sending master screen information to the system bus 33.

On the other hand, booth 82 shows the general equipment used by students in the educational support system, and like the master 31, it includes a word processor main body (word processor) 3B, a keyboard (KB
) 39 and a monitor (CRT) 40, and an operation panel 41 connected to this word processor. The operation panel 41 is a booth-side operation device used to exchange image information and audio between the master 31 and the booth 32. As shown in FIG. 3, this operation panel 41 includes a control section 61, an interface (IF) 62, an I1
0 port 63 and a screen changeover switch 64.

The control unit 61 has a function of following the control of the master 31. The interface 62 is the system bus 3
3 to connect the word processor main body 38 on the booth 32 side. I
The 10 boat 63 performs input control of various switches provided on the main body of the booth operation panel (not shown), including the screen changeover switch 64. The screen switching switch 64 specifies the screen switching mode, and the screen viewing switch 54 on the master 31 side
This is a switch for receiving master screen information sent to the system bus 33 by the operation of .

Note that a plurality of booths 32 can be connected to a single master 31, and here, a plurality of booths indicated as booths 1 to n are connected to the master 31 via a system bus 33.

Moreover, FIG. 4 is a diagram showing the structure of the booth list sheet of the same embodiment. The booth list sheet 71 is made of a material such as plastic that can be written with a marker or the like, and has a plurality of switch holes 72a, 72b,
72c... This switch through hole 72a
s 72b 172c... are a plurality of booth selection switches 2 provided on the operation panel main body 21 shown in FIG.
2a s 22b s 22c..., and here, one hole is provided corresponding to one example switch.

Next, the operation of this embodiment will be explained.

The monitor 36 of the master 31 and the monitor 40 of the booth 32 are
They are coupled by respective interfaces 52.62. What information is projected onto each monitor 3B, 40 is usually determined by the operation panel 37 on the master 31 side.
It is controlled by operating the .

That is, for example, when it is desired to project screen information of the master 31 (master screen information on the monitor 36) onto the monitor 40 of the booth 1, a switch on the master operation panel body having that function is operated. By operating this switch, the screen information projected on the monitor 3B is transferred to the interface 5.
2 to the information bus 33a of the system bus 33. Here, the control unit 51 in the operation panel 37 controls the interface 62 of the booth 1 through the control bus 33b, and transfers data on the information bus 33a to the booth 1.
This information will be imported into Booth 1 as monitor information.

By performing such control, the master screen information becomes the monitor screen information of the booth 1 as it is.

Incidentally, such exchange of screen information is always performed through the operation panel 37 of the master 31, and cannot be performed when the master is absent (when the teacher operating the operation panel 37 is absent). In such a case, the screen viewing switch 54 and the screen changeover switch 64 provided on the respective operation panel bodies of the master 31 and the booth 32 are used.

In the master 31, when the screen viewing switch 54 is operated, the screen viewing mode is set. When this screen viewing mode is set, the control unit 51 in the operation panel 37 transfers the screen information projected on the monitor 36 to the system bus 33.
The information is sent to the information bus 33a. In this case, the control unit 51 only sends master screen information to the information bus 33a via the interface 52, but does not control the interface 82 of the booth 32 via the control bus 33b as described above.

Therefore, at this time, the master 31 is connected to the information bus 33a.
Although the information being projected on the monitor 36 has been sent out, this information has not yet been taken into the booth 32 as booth monitor information. Therefore, the booth 32 controls its own interface 62 by operating the screen changeover switch 64, and takes in the data on the information bus 33a as booth monitor information.

That is, in the booth 32, the screen changeover switch 64
When you operate , the screen switching mode is set.

When the screen switching mode is set, the control section 61 in the operation panel 41 connects the information bus 3 through the interface B2.
The data on 3a is taken in and projected on the monitor 40 as monitor information. If the screen changeover switch 64 is operated again, the data on the information bus 33a will be transferred to the booth 32.
be separated from Thereby, in the booth 32, self-view information can be projected onto the monitor 40.

In this way, the gate between the booth 32 and the system bus 33, which normally depends on the control of the master 31, is separated from the control of the master 31 by operating the screen viewing switch 54, and is always kept open. On the other hand, on the booth 32 side, by operating the screen viewing switch 54, information on the information bus 33a can be received without intervention from the master 31. Therefore, the master screen can be obtained optionally by operating the booth's panel, making it possible to conduct self-study classes as seen in normal school education. This system can be used even at times.

In addition, in the master 31, the operation panel main body includes:
A plurality of booth selection switches 22a as shown in FIG.
, 22b, 22c... are arranged, and by operating the booth selection switches 22, 22b, 22c..., any one of the plurality of booths 32 indicated by booths 1 to n can be selected. Ru. In the example of FIG. 7, 64 booths can be selected by combinations of rAJ to rHJ and "1" to "8". Usually, booth selection switch 22 a 122 b 522 c...
- has only a physical number indicating the switch arrangement, such as A1.81, and the booth selection switch 22a
When operating the s22b, 22c, etc., a list containing the switch number and student name is required.

In such a case, the booth selection switch 22a122
b, 22c, etc., that is, the student name, are entered in the booth list sheet 71 shown in FIG.
22C..., it is possible to grasp the input target of the switch through the same sheet 71.

Therefore, it is possible to select a desired booth in a short time without requiring a list containing switch numbers and student names, and it is also possible to prevent selection errors and the like.

[Effects of the Invention] As described above, according to the present invention, the master side specifies the screen viewing mode and sends master screen information to the system bus,
Since the screen switching mode is specified on the booth side and the master screen information on the system bus is received without intervention from the master, the master screen can be obtained arbitrarily by operating the panel on the booth side, and the master screen is not present. This system can be used even at any time.

In addition, in correspondence with the multiple booth selection switches provided on the master operation panel, we have provided a sheet in which the input targets for the switches are written, so when selecting a booth on the master side, the switch number and student name can be written down. The desired booth can be selected in a short time without requiring a list.
