Description

[Detailed Description of the Invention] The present invention relates to a material presentation device that displays various materials on a monitor television built into the device.

In the past, various materials presentation devices with a so-called lectern-shaped external appearance have been proposed and put into practical use. The problem is that many of these products have an irregular shape, making it inconvenient to transport and store the product.

Regarding the presentation function, conventional products have the function of enlarging the document and projecting it on a monitor TV, but in order to freely select any part of the document and enlarge and display that part, you have to move the document on the shooting screen. There is an inconvenience that must be had.

The present invention was devised in view of the above-mentioned difficulties with conventional document presentation devices, and its configuration is such that a screen for photographing documents is formed on the top plate of a table-shaped main body, a monitor TV is installed, and In a document presentation device in which a television camera is installed in a storage section formed at the bottom of the top plate of the main body, standing walls are formed on three sides of the periphery of the top plate except for the front side, and a wall is placed on the top of the top plate at the top of the standing wall. A narrow sub-top plate that covers the front part is mounted, and a monitor TV is housed in the space formed by the sub-top plate and the top plate, while the screen is placed in the housing part of the table-like main body. The present invention is characterized in that a light source for irradiation is provided, the screen and the television camera are moved relative to each other, and a reflecting mirror is provided to direct the incident optical axis of the camera to the screen.

Next, an example of implementation of the present invention will be explained with reference to the drawings.

1 is a box-like table-like main body, and a top plate 1a with a rectangular plane.
, both side panels 1b and 1c, and the panel 1
The outer shape is composed of d and 1e. Accordingly, in the present invention, the upper portions of the side panels 1b, 1c and the front panel 1d are formed into standing walls 11b, 11c, 11d that protrude relatively largely from the upper surface of the top plate 1a.

Reference numeral 2 denotes a sub-top plate installed above the vertical walls 11b to 11d, and the top plate 2 is sized to cover only the front side of the top plate 1a. Therefore, both the above-mentioned top plates 1a, 2 and the standing walls 11b, 11c, 11
A monitor television 3 is housed in the space surrounded by d. 4 is a screen for photographing materials formed in the center of the top plate 1a, and 5 is a storage area surrounded by the top plate 1a and each of the panels 1b to 1d. A television camera 6 is suspended inside the front panel 1d, and reflecting mirrors 7 and 8 are disposed on the optical axis of the camera 6.

Here, the camera 6 is movably suspended from a Y-axis rail 61 via a roller 62, and the Y-axis rail 61 itself is suspended from an X-axis via a roller 63.
By being movably suspended from the shaft rail 64, the optical axis of the camera 6 can scan the screen 4 via the mirrors 7 and 8 in the X and Y axis directions. Although not shown, each of the rollers 62 and 63 is provided with a small motor as a drive source.
Further, the lens of the camera 6 includes a zoom lens 6.
By using the camera 6 and the action of the zoom lens 6a, the material on the screen 4 can be partially enlarged and photographed. The video output taken by this camera 6 is not only supplied to the monitor television 3, but also can of course be supplied to an external television.

Reference numeral 9 in the figure is an operation switch panel for the device of the present invention disposed on the top plate 1a, which is equipped with a power switch for the monitor television 3, television camera 6, etc., a light source switch, a camera movement switch, a zoom switch, etc. There is.

The basic function of the device of the present invention configured as described above is to photograph the material placed on the photographing screen 4 with the television camera 6, and project the image on a plurality of televisions including a monitor television. However, the device of the present invention has the following practical advantages over conventional products.

Since all the constituent members are housed within the external shape of the main body 1 of the teacher's desk, the overall external shape can be simplified and transportation and storage are convenient.

The monitor TV 3 consists of two top plates 1a and 2 and a standing wall 1.
Since it is surrounded by 1b to 11d, the image is not easily affected by indoor lighting and can be viewed as a clear image.

In the embodiment, since the television camera 6 is configured to scan the screen 4 in the X and Y axis directions, it is possible to easily take pictures of parts of the material.
If a zoom lens is used, partial enlarged images of a single document can be obtained while being arbitrarily and continuously changed.

Incidentally, in order to obtain such an effect, when the camera 6 is fixedly installed, the screen 4 may be provided movably in the X and Y axis directions with respect to the optical axis of the camera 6.
For example, the screen 4 may be movably mounted on a Y-axis rail, and the entire Y-axis rail may be movably mounted on an X-axis rail. In this case, the screen 4 is moved manually, but it goes without saying that it may be moved by itself using a drive source such as a motor.

The present invention is as described above, and the document presentation device is compact and smartly formed by eliminating any component parts that protrude outside the contour of the table-like main body, making it convenient to transport and store. Since it also has functions, it is useful as a data presentation device.
