Abstract

PURPOSE:To prevent a lecturer from disturbing the pace of his lecture and exceeding the time limit of his lecture, by projecting various information on a screen and displaying time information additionally. CONSTITUTION:A time information display part 4 consisting of, for example, a transmission type liquid crystal display is provided in a part of a light radiation face 11 of an OHP body 1, and an operating part 5 for the display part 4 is buried in the side face of the body 1. When the time of the time information display part 4 is set to, for example, the current time by the operating part 5 and a film 2 is set onto the light radiation face 11 of the OHP body 1 and a light source is lit, information on the film 2 is sent to a screen 3 through a lens system 12 and is magnified and projected, and simultaneously, the current time is projected onto a part of the screen 3. The time of the display part 4 can switched to an elapsed time or a left time and is displayed on the screen 3.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a projector having the ability to add clock information.

Prior Art For example, at a lecture, etc., 14 pieces of information are displayed on a screen using a projector for the purpose of enhancing understanding of the content of the lecture, and based on this information, explanations are given6.
5 It is often done.

Problems with the conventional technology However, if the lζ projector is used frequently, the speaker may not be able to check the elapsed time of the lecture because the entire venue is dark, even when looking at a clock in the venue. . As a result, speakers sometimes disrupted the pace of their lectures or exceeded their pre-determined lecture time by a wide margin, which could lead to the content of the lecture being boring and lack excitement. .

OBJECTS OF THE INVENTION The present invention has been made to eliminate the above-mentioned drawbacks, and an object of the present invention is to provide a projector that can project various information on a screen and at the same time additionally display time information.

Summary of the Invention A transparent time information display section is provided on the light emitting surface on which the light from the light source is emitted and the transparent medium on which information is drawn is set. can be projected onto the screen.

Effects of the Invention Clock information can be displayed along with various information on the same screen, and when used at lectures, etc., the presenter can be accurately informed of various times, and high-quality lectures can be expected.

Examples of the invention An embodiment of the present invention will be described below with reference to the drawings.

In this case, this embodiment uses an overhead projector (
Hereinafter, it will be abbreviated as OHP. ) shows an example in which this invention is applied.

Drawing JcJ6, 1 is the OHP body, C (7) OH
The P main body 1 has a built-in light source (not shown) and has a light emitting surface 11 that emits the light of J:, r4e lt (I through a light leaking lens) on the upper surface. By setting a transparent medium 2 such as a film on which information is depicted, the information on the transparent medium 2 is enlarged and projected onto a screen 3 via a lens system 12. A part of the light emitting surface 11 has a time information display section 4 .

The display section 4 is composed of a transparent display, for example, a transparent liquid crystal display. Also, the clock body (not shown) that drives the time display section 4 is connected to the OHP body 11?
, and its operation section 5 is embedded in the side surface of the OHP main body l. In this case, the one hour information display section 4 is the operating section 5.
The current time is determined by the operation.

It is possible to display elapsed time, remaining time, etc.

Next, I will explain the effect.

Now, use the operation unit 5 to set the display on the time information display unit 4 to, for example, the current time. In this state, set the transparent medium 2 on the light emitting surface ll of the OHP main body 1.

Turn on the light source. Then, the information on the transparent medium 2 is sent to the screen 3 via the lens system 12, enlarged and projected, and at the same time, the current time displayed on the time information display section 4ζζ is projected on a part of the screen 3. Further, in this state, if the display on the display section 4 is switched to elapsed time, remaining time, etc. using the E operation section 5, these times can be displayed on a part of the screen 3.

Therefore, in this way, it is possible to display various information and clock information on the same screen E1, so when using it for a lecture etc., the lecturer can display the current time, elapsed time, remaining time, etc. while looking at the screen. can be known with certainty. As a result, lecture n can consider the pace of the lecture and each part while looking at these times, so it is possible to expect a lecture with a lot of content.

Other Embodiments of the Invention The present invention is not limited to the above-mentioned embodiments, but can be implemented in any suitable vehicle form without changing the gist. For example, although part of the description in E is about an OHP, the invention can also be applied to other projectors.
