Abstract

(57) [Summary] [Purpose] To provide an overhead projector device that can easily create and modify manuscripts. [Structure] A magnetic medium in which a manuscript is stored as display data of a document or drawing created by a word processor, a personal computer, etc. is set in the magnetic recording device 3. The stored contents of the magnetic medium are read out under the control of the control section 2, and inputted to the liquid crystal display section 4 to be displayed as a picture. This picture is projected onto a screen by a light source 6 and a reflecting mirror section 7.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to an overhead projector device.

0002

[Conventional technology]

Traditional overhead projector devices handwrite documents and drawings on transparent film. It is now possible to print or copy a manuscript as a manuscript, and then project the picture of this manuscript onto a screen. there was.

0003

[Problem that the idea aims to solve]

This traditional overhead projector device requires a lot of effort to create manuscripts. Another drawback is that the manuscript must be recreated every time a correction is made.

0004

[Means to solve the problem]

The overhead projector device of this invention uses a liquid crystal display that converts display data signals into pictures. It is equipped with a display section, and images generated by the liquid crystal display section are projected onto a screen. Also, the main idea The proposed overhead projector device uses a magnetic medium on which the display data signal is recorded. The device includes a magnetic recording device that reads recorded content from the body and outputs it to the liquid crystal display section. may have been completed.

【Example】

Next, the present invention will be explained with reference to the drawings.

[0006] FIG. 1 is a block diagram of an embodiment of the present invention.

[0007] In FIG. 1, 1 is an operation switch section for performing various operations, and 2 is an operation switch section 1. receives a signal from the magnetic recording device 3, reads the signal from the magnetic recording device 3, and displays it on the liquid crystal display section 4. A control unit that sends a signal, 3 is a magnetic recording unit that reads out display data recorded on a magnetic medium. a recording device; 4 is a liquid crystal display unit that displays the data read out by the control unit 3 as a picture; 5 is a liquid crystal display unit; A power supply unit that receives external power supply and generates light source power for the overhead projector. , 6 is the light of the overhead projector that is supplied with power from the power supply unit 5 and emits light. 7 is a reflection that projects the picture created by the light source 6 and the liquid crystal display section 4 onto the screen. This is the mirror section.

[0008] Documents and drawings created using word processors, personal computers, etc. Place the magnetic medium on which the original is stored as display data into the magnetic recording device 3 and operate it. When the operation switch section 1 is operated, the control section 2 operates the magnetic recording device 3 and records the magnetic medium. The content stored in is read out as an electrical signal and input to the liquid crystal display section 4. . The electrical signal input to the liquid crystal display section 4 is processed inside the liquid crystal display section and displayed as a picture. shown. The displayed picture is illuminated by the light source 6 from the back side of the liquid crystal display section 4. Therefore, it is reflected onto the reflecting mirror section 7 and finally projected onto the screen.

[0009] Display data is sent directly from a word processor, personal computer, etc. to the control unit 2. The magnetic recording device 3 may be omitted if input is made directly.

0010

[Effect of the idea]

As explained above, the present invention is applicable to word processors, personal computers, etc. This has the effect of making it easier to create and revise the manuscript. Also, saving manuscripts on magnetic media can reduce unnecessary paper documents. There is fruit.
