Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate-like transparent member made of glass or the like, and a document is placed downward on a substantially horizontal flat surface. The present invention relates to a document positioning template used for a document camera device that captures a document of the document using a camera disposed below the document. 2. Description of the Related Art As shown in FIG. 4A, a document camera apparatus has a stage 1 made of a plate-shaped transparent member such as glass.
A document camera apparatus 100 in which a document 102 is placed downward on a document 01, and a document on the document 102 is imaged by a camera 103 serving as an image pickup means such as a CCD disposed below the document 102 to obtain image information. [0003] The acquired image information is transmitted to the projection device 104 by wire or wireless as an electric image signal, and is projected on a screen 105. A document camera device 100A with a projection function, in which the camera 103 and the projection means 106 constitute one device as shown in FIG. 4B, is also included in the category of the document camera device. A conventional overhead projector (hereinafter, referred to as OHP) having no function of converting document information into an electric image signal creates a document in which a document is printed on a transparent sheet for OHP, and places the document on a stage. Placed on
Light emitted from a light source arranged below penetrates the original,
Light including document information of a document is projected onto a screen by a magnifying lens and a reflecting mirror arranged above the stage. In this case, the reflecting mirror or the magnifying lens protruding above the stage may obstruct the field of view, and the manuscript of the transparent sheet must be prepared. However, the document camera apparatus described with reference to FIG. Thus, there is no protrusion above the stage and a plain paper original can be projected as it is, and further, a video signal or a computer image signal can be projected by adding a simple function. Therefore, in recent years, a combination of the document camera device 100 and the projection device 104 or the document camera device 100A with a projection function has been widely and generally used. In particular, in presentations, various expressions have been made possible by mixing the above-mentioned video signals and computer image signals with document documents. As shown in FIG. 5, the document camera apparatus can place a rectangular original such as Japanese Industrial Standard A row 4 on a glass stage 52 horizontally or vertically 51A or 51B. The entire reading range 53 is arranged such that the glass stage 52 and the center position Z are at the same position. When the document camera device has a zoom function, the same-size reading range 53A is
3 and the center position of the zoom reading range 54 is also
It is at the same position as the center position Z of the glass stage 52. Further, the length of the long side X of the reading range 54 at the time of zooming is set to the same length as the length of the short side Y of the same size reading range. That is, when the original is placed vertically as 51B, the entire width of the original in the width direction matches the projection range of the screen by the zoom function. Therefore, when the original is placed horizontally like 51A, the original is placed with a visual register so that the center of the original coincides with the center Z of the glass stage 52 so as to match the entire reading range. When the original is placed vertically like 51B, visual observation is performed so that the center of the original in the horizontal direction coincides with the center Z of the glass stage 52 so that the entire horizontal width coincides with the long side X of the reading range 54 during zooming. Place it with a guide. At this time, the vertical position of the document is set to a desired scroll position by visual registration. In this case, it is very difficult to position the original at an optimal position by visual registration. Usually, the position of the original is adjusted while looking at the screen on which the document of the original is actually projected, and the position of the presentation is adjusted. Then, temporarily presents unsightly images. This method has been commonly used in the past, and it is implicitly understood that it is difficult to avoid even for the audience of the presentation.However, in an effective presentation by mechanization in recent years, even if it is temporary, The ugliness of stopping the flow tends to be more pronounced. [0011] Here, the following improvement can be easily devised from the above-mentioned document positioning method. As shown in FIG. 6, in order to place a document horizontally like 51A, a line 6 serving as a mark for document positioning is placed near the outside of the corner of the entire reading range 53 of the glass stage 52.
Print 0. In addition, in order to place the original vertically, such as 51B, a line 61 serving as a mark for positioning the original in the width direction on the glass stage 52 is printed in an area that does not fall within the entire reading range 53. It is considered that if the original is placed on the glass stage 52 using the line 60 or 61 as a mark, the manual positioning of the original is facilitated. However, positioning and placing the original with the printed line as a mark requires a movement for simultaneously controlling the vertical and horizontal rotation angles of the original while visually observing the image. In this case, too, the position is adjusted while viewing the projected image on the screen. It is hard to say that it is a remarkable improvement as compared with the case where it does. Also, if an air layer is interposed between the glass stage 52 and the document and it is slippery,
It is not rare that the position is shifted again the moment the positioned hand is released. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and an original is brought into contact with a positioning template so that positioning can be easily performed without looking at a projected screen, and the present invention is effective. It is an object of the present invention to provide a document positioning template capable of performing a simple presentation. According to the present invention, an original is placed downward on a stage formed of a plate-like transparent member such as glass and having a substantially horizontal plane, and is disposed below the original. When using a document camera device that captures a document of the document with a camera, a U-shape is used, and a member that can be easily attached to and detached from the document camera device is used to form at least one right angle inside the U-shape. A first positioning unit formed by two sides formed by the first positioning unit and a second positioning unit formed by two sides formed by two ends of both ends of the U-shaped protrusion. It is an object of the present invention to provide a document positioning template characterized by facilitating the positioning of a general rectangular document either horizontally or vertically by contacting the document with the means. Embodiments of the present invention will be described below with reference to FIGS. 1, 2 and 3. FIG. 1 shows one embodiment of the present invention.
FIG. 1 is a perspective view showing an embodiment, and in FIG.
Denotes a document camera device, and 2 denotes a document positioning template. Reference numeral 3 denotes a stage peripheral portion formed on the same plane as the glass stage 52, and reference numerals 4A and 4B denote rib-like projections formed on the substantially vertical side surface 5 of the stage peripheral portion 3. The positioning template 2 is mounted in the direction of arrow A from above the document camera device 1 to allow the positioning template 2 to be mounted as shown in FIG.
And the function of document positioning can be achieved. FIG. 2 is a perspective view showing the lower surface of the positioning template 2. When the positioning template 2 is mounted on the document camera 1 as shown in FIG. 1A, the inner wall surface 7 of the positioning template 2 is attached to the document camera. 1, the rear surface of the projections 6A and 6B at both ends of the positioning template 2 is in contact with a surface 5A which forms one plane, and the rib-shaped projections 4A of the document camera device 1
4B. By the simple mounting operation as described above, as shown in FIG. 1 (b), on the upper surface of the document camera device 1, a side 8 and a side 9 which form a right angle inside the positioning template 2 are formed. The first positioning means and the second positioning means constituted by the sides 10 and 11 at the tips of both protruding portions of the positioning template 2 are arranged. As a result, as shown in FIG. 3 (a), when a rectangular original is placed horizontally, two sides intersecting the right angle of the horizontally placed original 51A are formed on the positioning template 2 by the first positioning means. Is positioned in contact with the sides 8 and 9 forming a right angle, and the position of the document coincides with the entire reading range 53. In addition, as shown in FIG. 3B, when a rectangular document is placed vertically, one side forming the long side of the vertically placed document 51 </ b> B is located on the side 1 of the tip of both protruding portions of the positioning template 2.
The document is positioned in contact with 0 and 11, and the position in the width direction of the document coincides with the long side X of the reading range 54 during zooming. Here, in this embodiment, the positioning of the original is realized by using two sides forming a right angle as the first positioning means in the positioning template 2, but the three inner sides of the U-shape are used by using the three sides inside. It is self-evident that the same effect can be obtained by positioning the document so that it fits in the document. In this embodiment, as a method of mounting the positioning template 2 to the document camera device 1, rib-shaped protrusions 4 A, 4 B on the back of the projections 6 A, 6 B at both ends of the positioning template 2 are provided. However, the present invention is not limited to this method, and even if a method using the fitting of unevenness such as a pin and a hole or a method using a Velcro tape is selected, the positioning template 2 for the document camera apparatus 1 can be used. Easy detachment is possible. According to the present invention, by using a positioning template, it is possible to position a document only by contacting the positioning portion of the positioning template. As a result, it is not necessary to adjust the position and angle of the original while watching the projected screen image, and an effective presentation can be realized.
Further, the positioning can be performed easily, reliably, and in a shorter time than when positioning the document in accordance with the mark printed on the surface of the stage on which the document is placed. Further, in the document camera with projection function 100A as shown in FIG. 4B, the position of the screen 105 is set high as shown in FIG. 7, and the document camera with projection function 100A is tilted. It is common to use it. In this case, the presence of the positioning template 2 can prevent the document 102 from sliding in the direction of arrow A. In addition, the positioning template can be easily attached to and detached from the document camera device, so that even a document larger than a specified paper size can be easily placed.
