Description

  The present invention relates to a lecture bulletin board, and more particularly to a lecture bulletin board having a simple structure and allowing a lecturer to easily read a manuscript without affecting the audience viewing the lecturer.

  Currently, when speaking at public gatherings, many speakers, with the exception of a small number of improvised speakers, either hold the manuscript by hand or use the manuscript as the stage for the lecture.

  When a speaker gives a lecture using a manuscript, the speaker puts the text written on the page in the visual range at the same time, making it difficult to read the sentences following the moment, and misreading or misreading. There is. In addition, since the font size cannot be adjusted as necessary, the speaker is always worried that reading one sentence will miss the entire lecture. As a result, the reading process proceeds with the manuscript being looked at, and the reading format is unknowingly unknown. As a result, the atmosphere of the entire lecture may change.

  When a lecturer gives a lecture at an indoor venue, classroom or outdoor construction site, airport, plaza, etc., the manuscript may be blown by a fan, mechanical wind, natural wind, or may be damaged by rain. Therefore, the contents of the lecture may not continue as planned.

  In addition, the speakers will be able to express the content of the lectures vividly and not to be regarded as readers or speakers who simply read the text aloud, while looking at the audience or students while speaking, While observing the order, add gaze, hand posture, or expression to move the gaze to the manuscript written on the page. At this time, if it takes too much time to search for subsequent sentences, the lecture will be interrupted and the atmosphere will be reduced. In addition, as a result of lecturer's disappointment, the evaluation of the lecture is greatly discounted, which may lead to failure of the lecture.

  It is necessary to solve the problem that the lecturer feels uncomfortable during the lecture due to the lecture manuscript.

  It is most common for speakers to speak while standing next to the desk. For this reason, it is necessary to reduce the size and weight of the lecture bulletin board so as not to disturb the speaker's line of sight or the viewer's attention.

  Accordingly, an object of the present invention is to provide a lecture posting apparatus that has a simple structure and allows a lecturer to easily read a manuscript.

  In order to achieve the above-described object, the lecture posting device according to the claims of the present invention includes a projection device and a display plate. The projection device can form an image on the display plate by projecting light rays onto the display plate, and the display plate is composed of several elongated objects that can receive the projected image, and these elongated objects are linked to each other. And there are gaps.

  The lecture posting apparatus includes a display plate capable of displaying an image. Among them, the display plate is composed of several elongated LCDs capable of displaying an image, and these LCDs are interlocked with each other and have a gap.

  The lecture posting device according to the present invention has a simple structure, and projects the content of the lecture on the display plate via the projection device or directly displays the content of the lecture from the elongated LCD display plate. The display plate is composed of several elongated objects that can receive a projection image, and these elongated objects are interlocked with each other and have a gap. For this reason, when viewing the bulletin board from the audience's direction, the line of sight passes through the gap between the narrow side (thickness direction) and the narrow side of the elongated object, so that the display plate cannot be seen and the narrow side of the elongated object is not visible. I can only see it. For the audience, the display plate appears to be nearly transparent. When viewed from the speaker's direction, a wide surface of an elongated object can be seen. In addition, the wide surface of the elongated object viewed from this direction constitutes the entire plate, so that the speaker can easily read the manuscript. In addition, each display plate is positioned in front of the speaker so that the audience does not affect the viewing of the speaker, so that the speaker and the audience can discuss each other without bowing down and looking for the manuscript, It is possible to proceed with the lecture as scheduled. This encourages interaction between the speaker and the audience, and makes the lecture lively. Moreover, since the content of the projection is controlled separately, it is possible to provide the content of the lecture according to the needs of the speaker.

  In summary, the lecture posting device according to the present invention has a simple structure, and allows the lecturer to read the manuscript easily and allows the lecture to proceed smoothly.

Embodiments of the present invention will be described below with reference to the drawings.
As shown in FIG. 1, a lecture posting apparatus 100 according to a first embodiment of the present invention includes a projection apparatus 1, a mirror set 2, a display plate 3, and a box 4. Among them, the projection device 1 and the mirror set 2 can be mounted inside the box 4 or in a lecture stand. And these three are positioned under the lecture stand. The display plate 3 is mounted on a lecture stand, and the projection apparatus 1 can form an image on the display plate 3 by transmitting light rays and refracting the display plate 3 by the mirror set 2. Moreover, it is possible to make the lecture bulletin board 100 independent as a single facility.

  Since the projection apparatus 1 can be any of a CRT display plate or LCD display driven by a projector, electronic equipment, an LCD display, a slide film, an actual product, or a handwritten manuscript, the content required by the speaker is projected onto the display plate 3. Is possible. For example, when the projector 1 is a projector, the contents of the lecture are stored in advance in a computer and the projector and the computer are connected or combined together, and then the contents of the lecture are displayed on the display plate via the projector. 3 is projected.

  When the projection apparatus 1 is mounted horizontally inside the box 4, the angle between the mirror set 2 and the lens 10 of the projection apparatus 1 is constant. The light beam emitted from the projection device 1 is refracted on the rear back surface or front surface of the display plate 3 via the mirror set 2 and forms an image. At this time, the display plate 3 is placed at the position of the real image as shown in FIG. Such a method of mounting the projection device 1 in the vertical direction allows direct projection from the projection device 1 onto the display plate 3 without relying on the mirror set 2.

  When the projection device 1 is mounted in the box 4 in the vertical direction, the light beam emitted from the projection device 1 is refracted through the mirror set 2 or directly to the front side or the back surface of the display plate 3. Image. At this time, the display plate 3 is placed at the position of the broken line as shown in FIG. Such a method of mounting the projection apparatus 1 allows direct image formation from the projection apparatus 1 onto the display plate 3 without relying on the mirror set 2.

  When the projection apparatus 1 projects a light beam on the rear back surface of the display plate 3 to form an image, the display plate employs a pattern material that can transmit the back light, so that the speaker can read the pattern contents. Is possible. Both of the above-described methods of projecting images on the two display plates can display clear images to the speaker. Further, when the projection device 1 projects onto the front side plate of the display plate 3, the content of the lecture on the projection device 1 is placed upward, and when projected onto the back side plate of the display plate 3, the content of the lecture on the projection device 1 By placing the face down, it is possible to show the image of the speaker facing the front in front of the front surface of the display plate.

  The mirror set 2 is composed of several reflecting mirrors, and includes a translucent mirror, a plane mirror, or a curved mirror. Further, the mirror set 2 can obtain a relatively large projected image by changing the direction of the light beam projected from the projection device 1 and increasing the space and distance between the lens of the projection device 1 and the plate. Further, in order to obtain a relatively large projection image under a relatively small space and distance, it is possible to employ an optical system such as a combination of translucent mirrors or a curved mirror. Therefore, since the image projected on the display plate 3 is sufficiently large and clear, it is possible for the speaker to easily identify the image.

  As shown in FIG. 2, the display plate 3 is mounted on a lecture stand and is composed of several elongated objects 30. The elongated object 30 is composed of an elongated mirror, slat or elongated LCD. The elongated object 30 is shaped like a bride and its relative angle can be fixed or adjusted. The elongated object 30 has a slat-like shape with a constant width and a relatively thin side surface. The elongated objects 30 are interlocked with each other and have a gap. At the same time, the surface of the elongated mirror, slat, or elongated LCD facing the audience is thin, so it looks almost transparent when viewed from the audience. Further, since the gap can transmit light, it is possible to show the speaker to the audience. When viewed from the speaker's direction, because of the viewing angle, the speaker saw a planar portion of an elongated object, and several elongated objects appear to be composed of a single plane and projected from the projector. It is possible to receive images. While the projector projects onto all elongate objects, all elongate objects each receive a partial image, but can be combined to form an entire image.

  The elongated object 30 is made of a metal or non-metal material, and can be any of a flat surface, an arc surface, a curved surface, or a mixed surface. Alternatively, any of translucent and the like is possible. For example, there are screens, rear projection television screens, and the like.

In order to connect or support the elongated object 30, the following method is used.
In the first method, fixing holes (not shown in the figure) are provided on both long side edges of the elongated object 30 in parallel, a frame 34 is provided at the long end, and a through hole is formed at a position corresponding to the fixing hole of the frame 34. (Not shown in the figure) is provided, and then the elongated unit 30 is supported and fixed by passing through the through hole and the fixing hole by the fixing unit 32. It is possible to control and adjust the inclination of the elongated object 30 by adjusting the frame 34.

  The second method is to form the elongated object 30 into a shape like a bride. Since such a molding principle is simple, it can be completed by using a mold or combining them.

  The third method is to employ a fixing method such as a method in which a veneer plate is bonded between the elongated objects 30 with an adhesive or a bolt, or a method in which these are connected to an external solid.

  The fourth method is to fix the edge between each elongated object 30.

  By mounting a spring between the above-described through-hole 32 and the bolt 37, it is possible to adjust the relative inclination between the elongated object 30 and the speaker, that is, to reduce the disturbance of the audience's line of sight. The adjustment mechanism is a manual or mechanical adjustment device controlled by an electronic circuit.

  Such a configuration method of the display plate 3 is to realize that the display plate is interrupted, separated, or continuous based on the principle that the vision varies depending on the angle.

  As shown in FIG. 3A, when the audience looks at the lecture stand from the F1 direction, since the elongated object 30 is a thin slat, the audience sees the thin side of the elongated object 30. This thin side is nearly transparent without affecting the audience's line of sight, so you can't see the slats, but you can see the speaker well.

  As shown in FIG. 3B, when the speaker looks at the display plate 3 from the F2 direction, the F2 direction faces a wide surface of the elongated object 30, so that even if each slat displays a separated partial pattern, When viewed from the direction of the elongated object 30, an entire screen is formed. One side facing the speaker can display the entire video. Therefore, it is possible to clearly show the video projected from the projection device 1 to the speaker.

  Because the display plate is located in front of the speaker, it is possible to have the speaker and the audience face-to-face with each other without having to look down and look for the manuscript to see if the content is wrong. It is. This encourages interaction between the speaker and the audience, and makes it possible to activate the lecture.

  FIG. 4 is a schematic diagram showing the configuration of the display plate. A translucent film 36 having a certain angle is connected between the elongated objects 30 of the display plate 3. Such a structure is close to that of a paper fan. The structure of the elongated object 30 of the display plate 3 having such a structure is the same as described above. It is possible to coat the transparent film 36 connected thereto with a transparent film or to form a frame shape. Since one side facing the speaker is one of wiping, cloth, plastic, etc., it is possible to receive a projection image. Therefore, when the spectator looks from the F1 direction, the line of sight passes through the translucent film 36, but the entire screen cannot be seen. When the speaker views from the F2 direction, a single image as shown in FIG. 3 is seen.

  When the above-described display plate 3 is in an operating state, the structure exhibits a developed state, that is, a parallelogram. It can be closed when it is not operating. Such a closed state is the same as the structure when the paper fan is closed, and the display plate 3 that can be closed is housed in the box 4 and is therefore convenient for carrying. If such a structure is a fixed type, the totality is good.

  In such a display plate structure, the side surface of the elongated object 30 is a thin side, but has a certain thickness. If the side surface of the elongated object 30 is processed, a pattern is created, or a LOGO is attached, it is possible to transfer the audience's line of sight and obtain an advertising effect.

  The box 4 is a shell having a cavity in which the projection device 1 and the mirror set 2 can be mounted. By having the hole 40 for transmitting the light beam on the surface above the box 4, the light beam radiated from the projection device 1 is refracted through the mirror set 2, passes through the hole 40, and is connected to the display plate 3. It is possible to image. Moreover, it is possible to fix the display plate on the box.

  When assembling, if the projection device 1 is mounted in the box 4 and the mirror set 2 is mounted corresponding to the hole on the surface of the box 4, the light beam can pass through the mirror set 2 and the hole 40. . Finally, the display plate 3 is mounted at a position where the light beam emitted from the projection device 1 is completely received. Moreover, it is possible to align the projection apparatus 1, the mirror set 2, and the display plate 3 as one piece of equipment. This makes it possible to wear the lecture bulletin board 100 without much effort.

  In operation, as shown in FIG. 1, the projection device 1 is activated, and the contents of the lecture are projected onto the display plate 3 by a mirror set. When the projection apparatus 1 projects an image on a position indicating a real image of the display plate 3, the image is projected directly on the front plate of the display plate 3. When the projection device 1 projects an image on the display plate 3 at a position indicating a virtual image, the image is projected on the rear plate of the display plate 3. Since the lecturer stands in front of the front plate of the display plate 3, it is possible to view a front image on the front plate of the display plate 3.

  If the image is not clear, the focus of the projection device 1 or the mirror set 2 may be adjusted until the image becomes clear. In addition, by adjusting the inclination of the elongated object 30 of the display plate 3 according to the normal viewing direction of the speaker and the viewing direction of the audience, the viewing direction of the audience is dispersed from the display plate 3 to make the viewing direction of the lecturer a continuous screen. It is possible to stay.

  As described above, since the lecture bulletin board 100 is located in front of the speaker's line of sight, when the speaker reports, not only can he relax and read the contents of the lecture, but also encourage exchange with the audience. It is possible to make it lively.

  Since the height of the display plate 3 of the above-described lecture posting apparatus 100 is not fixed, it can be adjusted according to the height of the speaker. If the image projected on the display plate 3 is not clean even after adjustment, the focus of the projection device 1 or the mirror set 2 may be adjusted until the image looks clear.

The lecture bulletin board 100 described above is only one embodiment of the present invention. Other embodiments of the lecture bulletin board 100 of the present invention are as follows.
As shown in FIG. 5, the lecture posting apparatus 100 according to the second embodiment includes a projection apparatus 1, a mirror set 2, and a display plate 3. The projection device 1, the mirror set 2, and the display plate 3 are the same as the projection device, the mirror set, and the display plate described in the first embodiment.

  In this embodiment, the projection device 1 is mounted at an arbitrary position, the lens is directed to the mirror set 2, and the mirror set 2 is mounted on the ceiling or other place, so that the light beam projected onto the display plate 3 is emitted. Attach the display plate 3 where the speaker looks.

  In this embodiment, if the projection apparatus 1 is mounted in front of and behind the display plate 3 and the mirror set 2 is mounted at a position where the projection of the projection apparatus 1 can be received, the light beam can be projected onto the display plate 3. is there. When the projector 1 projects the light beam on the front side plate of the display plate 3 through the mirror set 2, the content of the lecture is placed in front. When the light beam is projected onto the rear side plate of the display plate 3 through the mirror set 2, the content of the lecture is placed on the opposite surface. You can read the contents of the lecture from the front and back of the display plate 3 toward the front. For this reason, it is necessary to employ a pattern material capable of transmitting back light for the display plate.

As shown in FIG. 6, the lecture posting apparatus 100 according to the third embodiment includes a projection apparatus 1 ′, a pattern curtain 2 ′, and a display plate 3.
In the present embodiment, the pattern curtain 2 ′ is any one of subtitles, screen televisions, other displays, and real objects. The display plate 3 is composed of an elongated mirror, and the content displayed on the pattern screen 2 ′ is reflected from the display plate 3, so that the speaker can read the content of the pattern screen 2 ′ reflected from the display plate 3. Is possible. As long as the speaker reads the contents of the pattern curtain 2 ′ from the display plate 3, the pattern curtain 2 ′ can be mounted at an arbitrary position related to the display plate 3.

  The lecture posting apparatus 100 according to the fourth embodiment includes a projection apparatus 1 and a display plate 3 as shown in FIG. This embodiment has fewer mirror sets 2 than the previous embodiment, and the projection apparatus 1 directly projects an image on the display plate 3.

  In this embodiment, if the projection device 1 is mounted on the front of the display plate, for example, on the ceiling, wall, or stand, it is possible to project the pattern light beam directly onto the display plate 3. As shown in FIG. 1, since the display plate 3 presents various angles to the speaker, the display plate 3 can be viewed from above or below the speaker.

  In summary, the lecture posting device 100 according to the embodiment of the present invention projects the content of the lecture on the display plate 3 via the projection device 1 to form a clear image. Further, as long as the light beam can be projected onto the display plate 3, the mirror set 2 can be arranged in the light path between the projection device 1 and the display plate 3, and these three members can be set at arbitrary positions. is there. Such a lecture bulletin board device 100 allows the speaker to relax and read the contents of the lecture, so the lecture is not lively because of staring at the screen or memorizing the contents of the manuscript hard. That does not happen.

  As shown in FIGS. 8A, 8B, 8C, and 8D, the display plate 3 of the lecture bulletin board 100 according to the fifth embodiment is composed of several elongated LCDs. That is, the display plate 3 is formed by connecting several relatively short LCDs. The elongated LCD of the display plate 3 is fixed by a frame. Each LCD displays the contents of the part.
