Reference numeral 9 denotes a display device that displays screen information stored in the display control section 6.

Next, the operation of the first conventional example will be explained.

First, when the presenter instructs the screen to be displayed from the display control instruction section 1, the operation processing section 5 reads the instructed screen information from the information storage section 4, and sends the screen information to the display control section 6 along with the display instruction. The 0 display control unit 6 develops and stores the received screen information into two-dimensional pixel data, and displays the stored screen information using the display bag W9. At this time, when the presenter gives an instruction to operate the electronic pointer stick 14a, the operation processing section 5 sends the pointer stick display control section 7 to the pointer stick operation section 2.
It sequentially sends out the manipulated variables obtained more continuously, and also sends out a superimposed display instruction to the display control section 6. The pointer stick display control unit 7 determines the display position from the current display position W (the position in the initial state may be set arbitrarily) and the operation amount sequentially sent from the operation processing unit 5, and controls the display. The position is transmitted to the display control unit 6. The display control unit 6 superimposes the image of the electronic pointing stick on the determined display position of the already stored screen information, and displays it on the display device 9 as shown in FIG. 6(b).

A specific configuration example of this first conventional example is shown in FIG. 6(a), and the display control instruction section 1 that can input instructions using an input means such as a mouse or a touch panel as the instruction stick operation section 2 is configured as shown in the figure. Display screen monitor la, memo for oral explanation l
b, a time display IC 1, and an operation menu 1d. In addition, FIG. 6(b) is a diagram showing an example of a display screen,
An image of the electronic pointing stick 14a is displayed in a superimposed manner.

FIG. 5 is a block diagram showing the configuration of an information display and explanation device as a second conventional example.
0. Further, the remote control means 12a is composed of a display control instruction section 1 through which the presenter issues control instructions for display, etc., and a transmission processing section 11 that transmits the instructions from the display control instruction section 1 as a signal.

Next, the operation of the second conventional example will be explained.

First, the presenter uses the display control instruction section 1 of the remote control means 12a.
When an instruction is given to a screen to be displayed, the transmission processing section 11 transmits the instruction signal to the control means 8b.In the control means 8b, the reception processing section 10 receives the instruction signal, and according to this instruction, the operation processing section 5 stores the information. The screen information instructed by the section 4 is read out and the display control section 1 is instructed to display it, and the screen information is sent out. The display control section 6 develops the received image information into two-dimensional pixel data and stores it, reads out the stored screen information, and displays it on the display device 9.

Further, FIG. 7(a) shows a specific configuration example of this remote control means 12a, such as a previous screen display button 13a, a next screen display button 13b, a screen brightness adjustment button 13c, a focus adjustment button 13d2, a display on/off button An operation menu is constructed from 13a, and FIG. 13B is a diagram showing an example of the display screen.

As can be seen from this figure, since the control means 8b in the second conventional example does not have a function of superimposing and displaying the image of the electronic pointing stick 14a, the presenter must also hold the pointing stick 14b and point out the explanation part.

[Problem to be solved by the invention]

Since the conventional information display and explanation device is configured as described above, (1) In the first conventional example, the screen display control and electronic instruction stick display can be operated, but the presentation position is fixed, so the presentation Presenters cannot move around to observe the audience's reactions, or presenters cannot make effective presentations that strongly emphasize their own image to the audience.

(2) In the second conventional example, a remote control is used as a remote control means, but the pointing stick cannot be operated on the remote control, and the presenter must hold the pointing stick separately from the remote control, so the operability is extremely poor.

There were issues such as:
