Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an educational device suitable for application to a group language practice device, a group musical instrument practice device, etc., and particularly to a power supply control means thereof.

BACKGROUND TECHNOLOGY AND PROBLEMS In an educational device, for example, a group language practice device, a plurality of booths are provided for one console, and the power to each booth can be turned on and off freely from the booth side. being done.
On the other hand, the console side cannot freely control the power supply on the booth side.

Therefore, if the power of the booth is repeatedly turned on and off while the analyzer is operated to calculate the correct answer rate, etc., the number of attendees will change, making it impossible to obtain an accurate correct answer rate.

Also, even if the number of attendees changes due to a booth malfunction or a student leaving early, it is not possible to turn off the power to each booth independently from the console, so it is difficult to turn on the power to the booth, for example. Even if you leave early and leave early, the number of attendees will not change at all. Of course, even if the analyzer is operated in this state, accurate values cannot be expected.

Furthermore, in such a case, in order to turn off the power on the booth side, the teacher must go to the student's seat, which is somewhat inconvenient.

As described above, in the conventional power supply device for a language practice device, the analyzer cannot function properly, and there are noticeable inconveniences in use.

Purpose of the Invention Therefore, in this invention, it is possible to control the power on and off of the booth side only from the console side, so that even if the power of the booth side is repeatedly turned on and off, or the number of attendees changes due to early leaving, it is possible to control the power on and off of the booth side. This allows for immediate response.

SUMMARY OF THE INVENTION Therefore, in this invention, a power supply control means for a plurality of electronic devices provided on the booth side is provided, and this power supply control means can be controlled only based on a power on/off command signal provided on the console side. This is what I did.

Embodiment Next, a case in which an example of the teaching device according to the present invention is applied to a language practice device will be described in detail with reference to FIG. 1 and subsequent figures.

The educational device according to the present invention is equipped with a microcomputer and uses a display device to display all information such as the monitor on the side of the selection booth for teaching material content, the attendance status of students, etc. on the CRT, and to display the information on the display screen while looking at the contents on the display screen. This is a case where each corresponding mode can be selected by operating switching means provided on the display screen.

FIG. 1 shows the structure of an example of a transparent electrode switch which is a switching means provided on a display screen.

In the figure, S is a display screen, on the front of which a matrix-like switch pattern 4 is formed by disposing a transparent electrode 2 formed in a rectangular shape connected in the horizontal direction and a transparent electrode pattern 3 formed in a rectangular shape connected in the vertical direction, facing each other. It is formed. Although not shown, a lead wire 5 connected to a control circuit or the like is connected to each end 2A, 3A of the transparent electrode 2 and the transparent electrode pattern 3.

This transparent electrode switch 1 has a transparent electrode pattern 3.
By pressing and deforming it with a finger or the like and bringing it into contact with the transparent electrode 2, only the contact portion becomes electrically conductive. As a result, information such as a switching signal is supplied to a predetermined control circuit connected to the contact part, and based on that information, each mode on the console side or the booth side can be realized, and the status is displayed on the screen S.
displayed above.

For example, when the transparent electrode pattern 3B in the sixth column from the left end in FIG. 1 is pressed with the finger 6, the transparent electrode pattern 3B is deformed by this operation, and
It comes into contact with the transparent electrode 2B in the row, and becomes electrically conductive. As a result, the fourth row of transparent electrodes 2B from the top end
A signal is supplied to a control circuit connected to the resistor electrode pattern 3B in the sixth row from the left end.

Therefore, information patterns corresponding to the various modes described above are displayed on the screen S, and one of the display parts corresponding to the selection key provided in the information pattern is displayed using this transparent electrode switch. If you select 1, each mode will be selected.

Figure 2 shows an example of the display pattern on screen S that is obtained when the attendance display mode is selected. In this example, a total of 20 booths are arranged in 4 rows horizontally and 5 rows vertically. Attendance status is displayed.

In the figure, solid diagonal lines indicate attendance status, and empty booths indicate absence.
This attendance display is performed by a control circuit 10 as shown in FIG.
This is done by the output of

FIG. 3 particularly shows the power supply control system of the control circuit 10, in which 10a is a control circuit provided on the console side, and 10b is a control circuit provided on the booth side.

The control circuit 10a is provided with a console-side CPU 11 and is also provided with power supply means 12 for the booth, and this power supply means 12 is controlled based on commands from the console-side CPU 11. Further, the console side CPU 11 is associated with a rigid switch S _REJ used to confirm student attendance.

The control circuit 10b provided on the booth side has a booth side CPU 20 as shown in the figure, and a tape recorder 21 for recording and reproducing the tape teaching material contents in each booth, or a speaker or microphone for responding to the console side. An amplifier system 22 and the like are provided. L is a lamp for displaying attendance.

These tape recorder 21, amplifier 22, indicator light L, etc. are all connected to power supply means 12 via power supply control means 25. Further on the booth side
The CPU 20 is directly supplied with operating power from the power control means 12. Also this booth side CPU2
2 is associated with the attendance switch S _ATD for attendance.

Next, the operation of this power supply control circuit 10 will be explained with reference to the flowcharts of FIGS. 4 and 5.

First, when the student turns on the attend switch S _ATD , the signal is taken into the booth side CPU 20 and an attendance signal is formed in step 30, which is sent from the booth side CPU 20 through the data line 27 to the console side CPU 1 in step 31.
1. When a power-on command signal is generated from the console-side CPU 11, it is captured by the booth-side CPU 20 (step 32), and the capture of this power-on command signal is prohibited (step 32).
33). This will cause the attendee to switch back to the Attend switch.
Even if S _ATD is turned on, the data will be transferred to the booth side CPU2.
Not included in 2.

After prohibiting the reception of the attendance signal in step 33, in step 34, the booth side CPU 20
A power-on command signal is sent to the power supply control means 25, thereby controlling the power supply control means 25 and turning it on, and power is supplied from the power supply means 12 to each electronic device (tape recorder 21, etc.) on the booth side. Ru. The power supply control means 25 is the CPU on the booth side.
The on state is maintained until a power off command signal sent from 20 arrives.

On the other hand, the console side CPU 11 performs operations as shown in FIG. That is, in step 40, the attendance signal sent from the booth-side CPU 20 is taken in, and in step 41, a power-on command signal is sent to the booth-side CPU 20 through the data line 27, and at the same time, the attendance signal is sent to the analyzer provided on the console side in step 42. Send a signal. This causes the analyzer to change its number of attendees.

At the same time, student attendance is displayed in step 43. For example, as shown in Figure 2, when the third student in the first row (booth B ₁₃ ) turns on the attendance switch S _ATD , his/her attendance status will be displayed on the display screen S provided on the console side. .

With such a power supply device, when the analyzer is performing an operation to calculate the student's correct answer rate, etc., the number of attendees for the analyzer will not change even if the attend switch S _ATD of each booth is turned on or off. Since it does not change, it is possible to calculate the correct answer rate based on the correct number of attendees.

FIGS. 6 and 7 are flowcharts of power supply control used in the event of a booth failure or students leaving early.

For example, when a student in booth B ₁₃ shown in FIG. 2 expresses an intention to leave early, the teacher at the console turns on the redirect switch S _REJ . As a result, the attendance status displayed on the screen S can be cleared. So booth B ₁₃
By pressing the corresponding transparent electrode switch 1, the display state of that part is erased (step 50). Next, in step 51, a power off command signal is sent from the console side CPU 11 to the booth side CPU 20 through the data line 27, and an absence signal is sent to the analyzer provided on the console side (step 52). This changes the number of attendees for the analyzer.

On the other hand, in the booth side CPU 20, the seventh
As shown in the figure, first in step 55, the power off command signal sent from the console side CPU 11 is captured, and this capture causes the booth side to
In step 56, the CPU 20 cancels the prohibition of the attendance switch S _ATD from receiving the attendance signal. Next, in step 57, a power off command signal is sent to the power supply control means 25 to turn off the power on the booth side (step 57).
58).

If configured in this way, all you have to do is check whether a student leaves early, press the Redirect switch S _REJ on the console, and then select and press the corresponding booth selection key displayed on screen S. The corresponding booth will automatically turn off. at the same time,
Since a change in the attendance signal is sent to the analyzer, an accurate value can be obtained even when checking the correct answer rate after leaving work early. Of course, the power supply on the booth side is controlled only from the console side, so you can save yourself the trouble of going to the booth you left early and turning off the power.

It should be noted that when the all key ALL (not shown) is turned on, all attendance displays are made to disappear. At the same time, all power to the booth is turned off.

Effects of the Invention As explained above, according to this invention, once the attend switch S _ATD is turned on at the booth side, the power will continue to turn on and off no matter how many times the attend switch S _ATD is turned on and off. is not affected at all, and since no signal for changing the number of attendees is sent to the analyzer provided on the console side, the correct answer rate on the analyzer can be accurately displayed.

In addition, since the power to each booth can be turned off independently on the console side, even if a student leaves the booth due to a booth malfunction or a student leaves early, the console will automatically turn off the power to the booth. Since the power can be turned off, it is extremely convenient for operation.
