JPH11281775A - Automatic notification buzzer sounder having electric light display function of presentation number and elapsed presentation time in research presentation meeting by infrared remote control operation - Google Patents

Abstract

PROBLEM TO BE SOLVED: To automatize and save power of works to show a presentation number plate and to measure elapsed presentation time with a stop watch for each presenter, and generate specific notification buzzer which have been done manually in a research presentation meeting. SOLUTION: This device is constituted of an electric light indicator using a luminous diode 2 in a sheet of printed board 1 and an electronic circuit with a digital integrated circuit element 3. By placing it at a easily visible location in a research presentation meeting place, time is notified to the meeting participants and the presenter. When the presenter started the presentation, the present presentation number is automatically indicated with electric light by operation pressing the start button of an infrared remote controller, and the indication of elapsed presentation time by light and measurement are also initiated. The device is constituted of an electronic circuit so that a notification buzzer is sounded with an automatic speaker 7 when each notification buzzer set time of a preliminary buzzer time setter 4, a presentation time ending buzzer time setter 5, and a question time ending buzzer time setter 6 set in advance of research presentation meeting initiation matches the research presentation times.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of displaying a presentation number and an elapsed time of each presenter in a conference at a conference or the like by using an infrared remote controller. It is a device that automatically generates a notification bell that notifies a predetermined announcement elapsed time. This device is composed of an electronic circuit combining a lightning display circuit and a digital circuit, and saves the work of progressing the presentation time at a research presentation.

[0002]

2. Description of the Related Art Conventionally, a presentation number at a research presentation is:
A clerk posted a number card for each presenter at the venue. In addition, for each research presentation, the presentation time and question time per person are determined, and furthermore, the notification bell occurrence time such as pre-bell, presentation time end bell, question time end bell is also determined, The attendant measured the elapsed time of each presenter with a stopwatch and used a push bell to generate a notification bell. As described above, the task of advancing the presentation time in a research presentation has been performed manually, and a device similar to the device of the present invention has not been used at all.

[0003]

SUMMARY OF THE INVENTION The present invention provides a method of displaying an announcement number tag, which has been conventionally performed manually, and measuring the elapsed time of an announcement with a stopwatch for each presenter. The task of generating a notification bell is to be automated to save labor.

[0004]

The device of the present invention can be notified to the participants and presenters of a research presentation site by installing the device in an easily viewable location of the research presentation site.
When the presenter starts a presentation, pressing the start button on the infrared remote control automatically increases the presentation number by one, and electronically displays the current announcement number, and also displays and measures the elapsed time of the announcement. Start. After that, prior to the start of the research presentation, pre-bell, presentation time end bell,
Each announcement bell is automatically generated when each announcement bell, such as the question time end bell, coincides with the announcement elapsed time.

[0005] The present invention comprises an electronic circuit in which an electro-optical display circuit and a digital circuit are combined. By the presenter or attendant pressing the start button on the infrared remote control,
The count-up of the announcement number and the clock counter of the elapsed time of the announcement start, and the electric light indicator displays the data of the counter of the announcement number and the elapsed time of the announcement by numbers from 0 to 9. The predetermined notification bell is configured by an electronic circuit so that the announcement elapsed time and both data of each notification bell time setting device are compared and automatically generated when they match.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, an embodiment of the present invention is an apparatus comprising an electronic display including a light emitting diode 2 and a digital integrated circuit element 3 on a single printed circuit board 1. Will be announced to the participants and presenters at the venue by placing it in a place easily viewable at the venue of the research presentation.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The electronic circuit constituting the apparatus of FIG.
This will be described with reference to the block diagram of FIG. First, before the start of the research presentation, the predetermined notification bell occurrence time is set by three sets of notification bell time setting devices 8. In addition, when the presentation number starts from one or more, the presentation bell is set. It is necessary to perform initial setting by the number initial setting device 20.

When the presenter starts a presentation, by pressing the start switch 12 or the start button of the infrared remote controller 13, a signal is generated from the start signal generating circuit 15, and the count-up signal of the presentation number counter circuit 19 is generated. And the count start signal of the announcement elapsed time counter circuit 16.

At this time, the announcement number is displayed on the announcement number electronic display 18 through the announcement number display drive circuit by the binary number output data of the announcement number counter circuit 19. Since the announcement elapsed time counter circuit 16 counts the one second clock pulse generated by the clock signal generation circuit 11, the announcement elapsed time is calculated. It is displayed on the display 17.

Further, the binary output data of the announcement elapsed time counter circuit 16 is input to one of the digital comparators 10, and the other input is connected to each notification bell time setting device 8. Here, in each of the notification bell time setting devices 8, each of the time setting devices of the pre-bell 4, the presentation time end bell 5, and the question time end bell 6 is constituted by a decimal digital switch so that the setting can be easily changed. The circuit is configured to switch in the order of the pre-bell, the end of the presentation time, and the end of the question time. Therefore, when the data of each notification bell time setting unit 8 and the elapsed time of the announcement coincide, an output signal is generated from the digital comparator 10.

The notification bell signal generation circuit 9 generates a signal having a different time width and a different number of times for each notification bell based on an output signal from the digital comparator 10. The announcement bell can be announced to the presenter by using a sound source such as an electronic sound or a bell or a buzzer by the speaker 7 and loudspeaking in the venue of the research presentation.

[0012]

Since a device similar to the device of the present invention is not used at all, if the device of the present invention is used in a research presentation, a simple operation of pressing the start button of the infrared remote control once is required. In addition, it is possible to smoothly perform the presentation time, reduce human burden, and save labor.
