[Problems to be solved by the invention]
However, these are all high-function screen-shared types, and have a problem that the device configuration is large and the price is relatively high.
[0005]
An object of the present invention is to provide an inexpensive device having both functions of an easy-to-view screen for projecting slides and images (also referred to as projection) at meetings and lectures and a whiteboard capable of performing writing for writing. Aim.
[0006]
[Means for Solving the Problems]
The present invention has been made to solve the above problems, and is a presentation device, comprising: a projector mounting section for mounting a projector; a transmissive screen for displaying various images projected from the projector; And a base for supporting the screen.
[0007]
According to the present invention, since a projector mounting section is provided, a commercially available projector can be mounted on the projector and used for presentation. In addition, the transmissive screen functions as a screen that displays various images from the projector, and also functions as a whiteboard that can be written or erased on its surface with a pen dedicated to a whiteboard. Therefore, compared to the conventional presentation device, it can be manufactured extremely simply and at low cost.
[0008]
In the presentation device, for example, a white board is further provided, and the base supports the transmissive screen and the white board.
[0009]
By doing so, it becomes possible to write on the whiteboard, and the visibility of the written content is improved.
[0010]
In the presentation device, for example, the transmissive screen and the whiteboard are each formed in a substantially rectangular shape.
[0011]
With this configuration, it is possible to form a single writing board in which the transmissive screen and the whiteboard are arranged adjacent to each other so that their surfaces are flush with each other. This means that writing becomes easier.
[0012]
In the presentation device, for example, the transmissive screen and the whiteboard are adjacent to each other.
[0013]
By doing so, the amount of movement of the line of sight between the transmissive screen and the whiteboard is reduced, so that it is easier to compare various images projected on the transmissive screen with the description of the images written on the whiteboard.
[0014]
In the presentation device, for example, the transmission screen and the whiteboard are flush.
[0015]
In this way, writing can be performed smoothly without being caught by the whiteboard pen or the like at the joint between the transmissive screen and the whiteboard.
[0016]
In the presentation device, for example, the projector mounting unit has a slide mechanism that slides the mounted projector with respect to the base.
[0017]
This makes it possible to appropriately project various images from the projector on the transmissive screen.
[0018]
In the presentation device, for example, the projector mounting unit has an angle adjusting mechanism that adjusts an angle of the mounted projector with respect to the base.
[0019]
This makes it possible to appropriately project various images from the projector P on the transmission screen.
[0020]
In the presentation device, for example, the transmission screen is a screen having a structure in which at least a screen sheet layer and a transparent panel layer are laminated in this order. This shows an example of the configuration of the transmission screen.
[0021]
By doing so, it becomes possible to write or erase on the surface of the transparent panel layer with a pen dedicated to whiteboard or the like.
[0022]
In the presentation device, for example, a protective layer for protecting the screen sheet layer may be further laminated on the transmission screen. The protective layer is, for example, a transparent panel layer.
[0023]
By doing so, it is possible to protect the screen sheet layer.
[0024]
Further, in the presentation device, for example, a reflector is further provided, and the projector mounted on the projector mounting unit projects various images on the transmissive screen via the reflector.
[0025]
In this way, the projection distance can be obtained in a relatively small space, so that the presentation device can be downsized. In addition, since the reflection plate covers the transmission screen, a shadow is formed on the rear surface of the transmission screen. This makes it possible to enhance the visibility of an image from the front of the transmission screen.
[0026]
In the presentation device, for example, the reflection plate is hinged to the base. In order to form a shadow on the rear surface of the transmissive screen, it is preferable that the hinge is provided on the base.
[0027]
In this case, the size can be reduced when the device is stored. Also, since the angle of the reflector can be adjusted, various images from the projector can be appropriately projected on the transmission screen.
[0028]

FIG. 2 is a diagram for explaining the structure of the transmission screen. FIG. 3 is a side view of the presentation device of the present embodiment.
[0029]
The presentation device 100 is a device used for a presentation at a conference or a lecture.
[0030]
As shown in FIG. 1, the presentation device 100 includes a transmission screen 110, a base 120, a projector mounting unit 130, a reflector 140, a sensor 150, a speaker 160, and the like.
[0031]
The transmission screen 110 is a screen for displaying various images projected (also referred to as projection) from the projector P mounted on the projector mounting unit 130. The transmission screen 110 is formed in a substantially rectangular shape, and as shown in FIG. 2, is a screen having a laminated structure (three-layer structure) in which a protective layer S1, a screen sheet layer S2, and a transparent panel layer S3 are laminated in this order. The protective layer S1 is for protecting the screen sheet layer S2, and is, for example, a transparent material made of an acrylic plate, a reinforced plastic plate, a glass plate, or the like subjected to an anti-reflection process. The transparent panel layer S3 is, for example, a transparent plate made of an acrylic plate, a reinforced plastic plate, or a glass plate. In addition, the same material as the transparent panel layer S3 may be used as the protective layer S1. The screen sheet layer S2 is, for example, a commercially available transmission screen. This is a translucent projection screen sheet, on the surface of which is formed a screen surface on which an image projected from the projector P is projected, and on the opposite surface thereof, a sealing surface. The transmissive screen is usually used by being attached to a shop window or the like via a sealing surface thereof.
[0032]
In the present embodiment, the transmission screen is attached to one surface of the transparent panel layer S3 via the sealing surface. Then, the surface of the transmission screen is covered with the protective layer S1. Thereby, the transmission screen 110 having a sandwich structure is obtained (see FIG. 2). As described above, since the protective layer S1 is provided, the screen sheet layer S2 can be protected. Further, it becomes possible to write or erase on the surface of the transparent panel layer S3 with a pen for exclusive use of a white board or the like.
[0033]
The base 120 supports the transmission screen 110. The base 120 includes a frame 121 for reinforcing the transmissive screen 110, a pair of legs 122, 122 for supporting the frame 121 from the left and right, and a reinforcing member 123 for connecting the pair of legs 122, 122. , 124.
[0034]
The pair of legs 122 is a bar-shaped member extending in the vertical direction, and their lower ends are formed in a T-shape in order to stably support the frame 121. The legs 122, 122 are connected by bar-shaped reinforcing members 123, 124, which extend substantially in the center and near the lower end, respectively, in the horizontal direction. For this reason, it is possible to use the presentation device 100 in a stable posture.
[0035]
At the upper ends of the legs 122, 122, the substantially central portions of the left and right frames of the frame 121 are rotatably mounted. This mounting method is the same as that of an existing whiteboard or the like. Therefore, the angle of the transmission screen 110 can be adjusted. Thereby, the visibility of the written contents and the like is improved.
[0036]
On the base 120 (frame frame 121), a reflector 140 for reflecting various images projected from the projector P and projecting it on the transmissive screen 110 is provided with hinge portions 125 on the frame frame 121 corresponding to the upper portion of the transmissive screen 110. Hinged through. The reflector 140 may be any as long as it can reflect various images projected from the projector P, and its material is not particularly limited. For example, the reflecting plate 140 can be a mirror-finished aluminum material, an acrylic plate, a glass plate, or a mirror. As shown in FIG. 3, the reflection plate 140 swings via the hinge 125 between a storage position P <b> 0 that makes almost surface contact with the transmission screen 110 and a use position P <b> 1 that forms a predetermined angle with the transmission screen 110. It is possible.
[0037]
In addition, both ends of the angle adjusting arm 141 are connected to substantially the center of the side surface of the reflection plate 140 and the substantially center of the one leg 122 via hinges H1 and H2, respectively. As shown in FIG. 3, the angle adjusting arm 141 includes a cylindrical member 141a having a predetermined length, a rod-shaped member 141b having a smaller diameter than the cylindrical member 141a and being coaxial with the cylindrical member 141a, and a cylindrical member 141a. It has a screw hole 141c penetrating from the inner surface to the outer surface, and a screw 141d screwed into the screw hole 141c.

Accordingly, the reflector 140 can be maintained at a predetermined angle with respect to the transmissive screen 110 by swinging the reflector 140 so as to form a predetermined angle with respect to the transmissive screen 110 and tightening the screw 141d. Has become. Thus, by adjusting the angle of the reflection plate 140 with respect to the transmission screen 110, various images from the projector P can be appropriately projected on the transmission screen 110.
[0039]
As described above, since the projection is performed by using the refraction (reflection plate 140) from the rear surface of the transmission screen 110, the projection distance can be obtained in a relatively small space, and the size of the presentation device 100 can be reduced. Further, since the reflecting plate 140 covers the rear surface of the transmission screen 110 as if it were a roof, a shadow is created on the rear surface of the transmission screen 110. This makes it possible to enhance the visibility of the image from the front of the transmissive screen 110. For this reason, the reflection plate 140 is formed in a substantially rectangular shape having substantially the same width as the transmission screen 110, but is formed slightly longer than the transmission screen 110 (see FIG. 3 and the like).
[0040]
Further, a projector mounting section 130 is provided on the base 120 (the reinforcing member 124). The projector mounting section 130 is for mounting the projector P. The projector P is connected to an information processing terminal or the like (not shown) such as a personal computer. Various images (slides, moving images, still images, etc.) input from the information processing terminal or the like are connected to the projector P. It has a function of projecting various images. As described above, since the projector mounting unit 130 is provided, various commercially available (general-purpose) projectors can be used as the projector P. Further, since the projector P is detachable, it can be made compact when stored.

The projector mounting unit 130 has a slide mechanism for sliding the mounted projector P back and forth with respect to the base 120 (reflecting plate 140), and an angle between the mounted projector P and the base 120 (reflecting plate 140). An angle adjustment mechanism is provided for adjustment. Therefore, by adjusting these mechanisms, various images projected from the projector P can be appropriately projected on the transmission screen 110.
[0042]
Various types of slide mechanisms are conceivable. For example, the projector mounting section 130 is attached to the projector mounting section main body 131 via a projector mounting section main body 131, a front-rear extending rail (not shown) mounted on the projector mounting section main body 131, and the rail. The projector P includes a projector mounting plate (not shown) capable of fixing the projector P by screwing or the like, and a screwing portion (not shown) for screwing and fixing the projector mounting plate at a predetermined position. This allows the projector P to slide back and forth by moving the projector mounting plate along the rail.
[0043]
Also, various types of angle adjusting mechanisms are conceivable. For example, the projector mounting portion 130 is configured by a bearing portion B rotatably attached to the reinforcing member 124 and a screwing portion (not shown) for screwing and fixing the projector mounting portion 130 to a predetermined position. Thus, the angle of the projector P can be adjusted via the bearing portion B.
[0044]
A commercially available sensor 160, speaker 170, and the like can be mounted on the base 120 (the right portion of the frame 121, etc.).
[0045]
The sensor 150 is for sensing the movement of a whiteboard pen or the like and inputting the movement to an information processing terminal such as a personal computer. The information processing terminal stores, displays, and prints the data. The speaker 160 is for outputting, for example, a voice or the like emitted by a user of the presentation device 100.
