Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a physical projector called an opaque projector.

[Conventional technology]

As shown in FIG. 2, a conventional actual projector has a box-shaped stand support 2 that is erected on the rear part 1a of the stage 1 in an inclined manner so as to project upward from the stage 1.
A first reflecting mirror 5 facing the lower head window hole 4 and a second reflecting mirror 6 facing the first reflecting mirror 5 are disposed inside the upper end head 3 of the stand support 2. In addition, a television camera 7 is installed inside the stand column 2, and the subject 8 (for example, a photograph) placed on the stage 1 or the experimental state to be carried out on the stage 1 can be viewed in the first and second positions. It is configured to take pictures with a television camera 7 through reflecting mirrors 5 and 6, and display the photographed images of this television camera 7 on a television 9.

[Problem that the invention attempts to solve]

The conventional physical projector can project the image of the subject photographed by the television camera 7 onto the television 9 and view it on the spot, but since the television camera 7 cannot record or play back recordings, it cannot be viewed on the stage 1. This is inconvenient when you want to take a photo of the experimental state you are conducting. In other words, in the case of the television camera 7, the experimental conditions carried out on the stage 1 can be viewed on the television 9, but this can only be done once, and the same experimental condition cannot be viewed over and over again. There is a problem.

Furthermore, since the television camera 7 cannot record or play back recordings, even if it is possible to remove it from the camera attachment part (inside the stand column 2) and connect it to a TV in another location, the recorded and played images cannot be copied to the TV in another location. There is also the problem that it is not possible to show it.

[Means for solving problems]

In order to solve the above-mentioned conventional problems, the actual projector of this invention uses an integrated video camera 10 with a built-in cassette having a recording function or both recording and playback functions in place of the conventional television camera 7. A video camera 10 is removably mounted on a camera mounting section 11.

[Effect]

According to the actual projector having the above-mentioned configuration, the experimental conditions etc. to be conducted on the stage 1 are photographed by the integrated video camera 10, and the photographed images are displayed on the television 9 and simultaneously recorded on the cassette with the built-in camera. You can play this recording and watch it as many times as you like. Furthermore, it is also possible to remove the video camera 10 from the camera mounting portion 11 and connect it to a television set at another location, thereby allowing recorded and reproduced images to be viewed on the television set at another location.

〔Example〕

Hereinafter, an embodiment of this invention will be described with reference to the drawing in FIG. A box-shaped stand column 2 is installed in an inclined manner so as to extend upward from the table, and a first reflecting mirror 5 is disposed inside the head section 3 at the upper end of the stand column 2, facing the window hole 4 on the lower side of the head.
and a second reflecting mirror 6 facing this first reflecting mirror 5.
The internal position where the box rear cover 2a of the stand column 2 is attachably attached is a camera mounting part 11, and the camera mounting part 11 has a built-in cassette having a recording function or both recording and playback functions. An integrated video camera 10 is removably attached, and the subject 8 placed on the object table 1 or the experimental state carried out on the object table 1 is monitored through the first and second reflecting mirrors 5 and 6. The video camera 10 is configured so that the image taken by the video camera 10 can be displayed on a television 9 and simultaneously recorded on a cassette (not shown) with a built-in camera.

[Effect of idea]

Since the actual projector of this invention uses the integrated video camera 10 as described above,
An integrated video camera 10 is used to record the subject 8 placed on the stage 1 or the experimental state conducted on the stage 1.
The user can take a picture with the camera, display the photographed image on the television 9, and simultaneously record it on a cassette built into the camera, and can play back this recording and watch it any number of times. Further, the video camera 10
Since it is removably attached to the camera mounting part 11, it is also possible to remove the integrated video camera 10 from the camera mounting part 11 and connect it to a television set in another location, so that recorded and played back images can be viewed on the TV set in another location. becomes.

Claims (1)

[Scope of utility model registration request] An object 8 on the stage 1 is photographed by a television camera 7 through a first reflecting mirror 5 located above the stage and a second reflecting mirror 6 facing the first reflecting mirror 5. In an actual projector in which images captured by a television camera 7 are projected onto a television 9 for viewing, an integrated video camera 10 with a built-in cassette having a recording function or both recording and playback functions is used in place of the television camera 7. , an actual projector characterized in that the video camera 10 is removably mounted on a camera mounting section 11.
