Description

  The present invention relates to an interactive environment construction method and a projector self-propelled support device used therefor. More specifically, a personal computer screen or the like is projected, or a dedicated electronic pen or finger is used as an electronic board. The interactive environment can be constructed easily, quickly and at low cost, and is suitable for implementation in educational institutions such as schools and related facilities, general companies, showrooms, event venues, large space facilities, etc. The present invention relates to an interactive environment construction method and a projector self-propelled support device used therefor.

  Along with the development and evolution of the information society, the use of projectors from the traditional forms of expression such as blackboards using chalk or whiteboards using markers in educational sites such as schools and corporate training rooms, etc. The construction of a so-called interactive environment that makes full use of IT, such as projection, display of a personal computer screen with a personal computer, and writing on an electronic board using an electronic pen or finger, etc., is strongly demanded. It is becoming.

  In constructing this interactive environment, it is called an electronic board, that is, a so-called interactive board including a flat-screen TV display for displaying images such as a personal computer and a DVD, and a white board that also serves as a projector projection screen. It is necessary to prepare a type of electronic board.

  However, in order to install this interactive board, there is a cost for installation work as well as the cost of the equipment itself. In many cases, an old blackboard or white board is already installed at the installation location. Therefore, there are restrictions on the installation location.

  On the other hand, there are many requests to use existing blackboards and whiteboards (including not only fixed walls but also movable ones) together with interactive boards. In that case, it is not only troublesome and troublesome to provide an interactive board and a projection screen each time, but also space constraints may be imposed. Furthermore, if the interactive board or screen for projection is separated from the blackboard or whiteboard for writing, it will be inconvenient to compare the projection items on the interactive board or screen with the written items on the blackboard or whiteboard. .

  Therefore, it is considered to add an interactive board function to a wall surface fixed board such as a blackboard or a white board in advance. For example, in Patent Documents 1 to 3, a rail is provided along the front or upper frame rear surface of the upper and lower frames of an existing wall surface fixed board, and a board having functions such as an electronic board and a screen is provided along the rail. It has been proposed to add functions such as an electronic board and a screen by slidably installing.

  However, when installing by this method, if the fixed wall type board is already installed, there is the trouble of having to remove the board itself or the rail each time it is installed or repaired. In addition, there is a problem that it is often impossible to perform construction when the existing wall surface fixed board is a UD type, a raising / lowering type or a draw type, or a curved surface type or a semi-curved surface type.

(It's just a wall, not a section.)

  The composite projector 8 used in the present invention has an interactive function by incorporating an interactive function in addition to a general projector function or by attaching an interactive unit. Here, the interactive function means that if you write on the projector projection surface using a dedicated electronic marker pen, finger, etc., the written characters and pictures will be transferred and stored in real time as electronic data to the personal computer via the interactive function section. This is a general term for a function that enables use as electronic data, a function that enables operation of a personal computer on the projection surface, and the like.

  As described above, the composite projector 8 enables the projection plane to be used as an interactive board even if the projection plane side is not provided with any function as an interactive board. A surface with a certain area is sufficient. Therefore, as described above, the projection surface is not only a board such as a white board or blackboard, but also a simple wall surface, floor surface, ceiling surface, door / window and other fittings, furniture, cloth surface, film surface. It may be a paper surface or a water surface. In the embodiment described later, a surface that moves together with the composite projector 8 is included.

  The composite projector 8 is movably installed, for example, on a peripheral wall or top surface in the classroom 1. For this purpose, the composite projector 8 is installed so as to be movable along a guide rail 9 disposed on the peripheral wall or top surface of the classroom 1. The guide rail 9 is arranged one-dimensionally, two-dimensionally or three-dimensionally on the projectable surface itself such as the whiteboard 5 or 6 or in the vicinity thereof. Therefore, the guide rail 9 may include a curved shape portion in whole or in part, and may include a twist shape portion in part.

Dimensional shape) or simply an I-shape (one-dimensional shape). Further, if the end of the guide rail 9 having the two-dimensional shape is extended toward the floor surface, it is a three-dimensional shape. The guide rail 9 does not necessarily have to be continuous, and may be intermittent. In this case, a plurality of composite projectors 8 are used.

  In the drawing, for the sake of convenience, the guide rail 9 is shown as if it exists on the floor surface of the classroom 1, but in reality, it is understood that the guide rail 9 in that case is arranged on the ceiling. I want to be. Further, in the figure, three composite projectors 8 are shown to indicate the movement position, but this does not necessarily mean that three composite projectors 8 are used.

  In addition, when the guide rail 9 is fixed to the peripheral wall or installed along the peripheral wall, the guide rail 9 is, for example, from the upper side of the front whiteboard (or blackboard) 5 on the front side through the wall surface 7 on the corridor side. Arranged in a U shape so as to reach the upper side of the rear whiteboard (or blackboard) 6, or arranged in an L shape extending from the upper side of the front whiteboard (or blackboard) 5 to the wall surface on the corridor side, or The front whiteboard (or blackboard) 5, the rear whiteboard (or blackboard) 6, or the corridor side wall surface 7 is arranged in an I-shape (linear shape).

  Although not shown, the guide rail 9 can be arranged not only in one classroom but also to extend to the next classroom, so that one composite projector 8 can be used in a plurality of classrooms. You can also.

  A cord for supplying power to the composite projector 8 (usually a curl cord) is housed in the guide rail 9 or suspended from the guide rail 9 via a runner. The guide rail 9 has a slide outlet function. By doing so, the codes can be omitted.

  Preferably, the composite projector 8 is movable along the guide rail 9. In this case, rail engaging means corresponding to the guide rail 9 is attached to the composite projector 8. The rail engaging means is, for example, a wheel that rotates in contact with the inner surface of the guide rail 6 having a C-shaped section. Of course, various other combinations of the guide rail 9 and the rail engaging means for the guide rail 9 are conceivable, and any configuration among them can be adopted. The movement of the composite projector 8 along the guide rail 9 can be performed automatically or by a human operation.

  In the example shown in FIGS. 2 and 3, the composite projector 8 is automatically operated in the horizontal direction along the projection target surface such as the peripheral wall or in the vertical direction (from the peripheral wall toward the ceiling surface or toward the floor surface). It is intended to run. In this case, the guide rail 9 is fixed to the peripheral wall or the like, or is arranged close to the peripheral wall or the like, but the illustrated example relates to the latter, and the composite projector 8 is supported by the self-propelled support device so as to be self-propelled. ing.

  The guide rail 9 there is fixed to and supported by the upper ends of a plurality of pole-shaped support stands 10, a rack 11 having teeth on the lower side, and a receiving member 12 arranged in parallel below the rack 11. It consists of

  The composite projector 8 is attached to the tip of a projector arm 14 that extends from a self-propelled portion 13 that is assembled to the guide rail 9. The wiring extending from the composite projector 8 is passed through the projector arm 14. The projector arm 14 is rotatably supported by inserting a receiving pipe 22 fixed to a support plate 21 provided horizontally at the upper end of the substrate 15 at the lower end thereof.

  The self-propelled portion 13 is fixed to the output shaft of the substrate 15, the forward / reverse rotation driving motor 16 installed on one side surface of the substrate 15, and the driving motor 16 protruding from the other side surface of the substrate 15, One or a plurality of lower horizontal rotating rollers 18, which are composed of pinions 17 meshing with the rack 11, are installed at the lower part of the substrate 15 and support the running and roll in contact with the front surface of the receiving member 12. And one or a plurality of upper horizontal rotating rollers 19 that roll on the back surface of the rack 11 and are placed on the upper surface of the rack 11. And one or a plurality of vertical rotating rollers 20 that rotate in contact with each other.

  The lower horizontal rotating roller 18 is pivotally supported at the horizontal portion of the angle member 23 fixed to the lower portion of the substrate 15, and the upper horizontal rotating roller 19 is pivotally supported at the horizontal portion of the angle member 24 fixed to the upper portion of the substrate 15. The vertical rotating roller 20 is pivotally supported at the vertical portion of the angle member 24.

  Further, a control panel installation base 25 is attached to the substrate 15, and a control panel 26 is disposed there. As the drive motor 16, either an AC type or a DC type can be used, and a corresponding device such as a battery or an AC adapter is built in the control panel 26. In a preferred embodiment, a reception sensor 31 that receives an instruction signal from a remote controller that is held by an operator is provided in the control panel 26.

  In a preferred embodiment, means for suspending the wiring 27 coming out of the control panel 26 in a bellows shape is provided. That is, a runner rail 28 is installed along the lower edge of the receiving member 12, and a number of runners 29 with rings that are movably engaged with the runner rail 28 are provided. Then, by passing the wiring 27 through the ring 30 of each runner 29 with a ring, the wiring 27 is suspended at appropriate intervals, and can be expanded and contracted appropriately in a bellows shape. Thus, when the self-running portion 13 moves, the wiring 27 is prevented from being entangled or obstructed, and the appearance is prevented from being deteriorated.

  In the above configuration, when the composite projector 8 is moved by operating the self-running unit 13, the drive motor 16 is rotated forward via the reception sensor 31 of the control panel 26, for example, by a remote control operation. As a result, the pinion 17 is rotationally driven, and the rotational driving force acts on the rack 11, but the rack 11 does not move, so the pinion 17 moves along the rack 11.

  During this moving operation, the load of the self-propelled portion 13 is received by the vertical rotating roller 20 rotating on the upper surface of the rack 11, and the tilt of the self-propelled portion 13 is received by the lower horizontal rotating roller 18. The upper horizontal rotating roller 19 is prevented from contacting and rolling with the rear surface of the rack 11. That is, the load of the composite projector 8 and the like related to the self-propelled portion 13 includes the force applied from the vertical rotating roller 20 to the upper surface of the rack 11, the force applied from the upper horizontal rotating roller 19 to the rear surface of the rack 11, and the lower horizontal rotating roller 18. Is supported by a balance of forces applied to the front surface of the receiving member 12.

  Then, when the composite projector 8 reaches the desired position, the operation of the drive motor 16 may be stopped. Moreover, the self-propelled part 3 can be moved in the opposite direction by rotating the drive motor 16 counterclockwise.

  In the example described above, the projection target of the composite projector 8 is assumed to be a fixed wall surface board such as an existing blackboard or whiteboard, or a wall surface or ceiling surface. In that case, an existing whiteboard or blackboard is assumed. It is possible to construct an interactive environment simply, quickly and at low cost by using these boards and walls as an interactive board without any modification.

  And since the compound projector 8 can move to arbitrary positions along the guide rail 9, in a large classroom etc., from the projection position with respect to a front whiteboard or a blackboard, a side wall and a white wall or whiteboard on the rear surface, or It can be moved to the projection position with respect to the ceiling surface for the convenience of students such as the backseat side, and the projection surface and the writing surface can be used close to each other. Blackboards and whiteboards can be used as they are.

  As described above, the guide rail 9 composed of the rack 11 and the receiving plate 12 is not necessarily a straight line, but may have a shape that is wholly or partially curved, or a shape that is twisted in the middle. can do. Therefore, for example, the guide rail 9 can be two-dimensional and three-dimensional layouts such as extending upward from the floor, curving at the upper part of the wall surface and extending in the lateral direction, and twisting along the ceiling along the ceiling. The application range is very wide. Further, since the guide rail 9 is not limited in length, it can be arranged over a plurality of chambers.

  The guide rail 9 and the self-propelled means shown in FIGS. 2 and 3 are not limited to the case where the projector is the composite projector 8 and can be applied to other types of projectors.

  Further, when the composite projector 8 is movable, the projection target surface is the above-mentioned whiteboard, blackboard or other wall-fixed or movable board, screen, wall surface, floor surface, ceiling surface, door, window, other fittings. In addition to the furniture, the cloth surface, the film surface, the paper surface, and the water surface, a moving projection surface 44 that is movably installed with the composite projector 8 is included (see FIG. 4). As the moving projection plane 44, a roll-up roll screen, a white board or the like is used, and the upper part thereof is fixed to the substrate 15.

  The method according to the present invention can be applied not only to the above-described wall-fixed board but also to an existing mobile board. That is, the mobile board is formed by supporting a board such as a blackboard or a white board with a stand provided with casters. In this case, an arbitrary upper side 42 of the board surface 41 to be projected is used. The composite projector 8 may be attached at the position (see FIG. 5).

  When the composite projector 8 attached to the upper side 42 of the board surface 41 is movable, the guide rail 9 is installed from the upper side 42 or from the upper side 42 to the side side according to the above embodiment, and the composite projector 8 Engaging means for the guide rail 9 may be provided at an appropriate position.

  In the case of this mobile board, it may be possible to use both sides of the board. In that case, the opposite surface can be used as an interactive board by rotating the projector arm and directing the composite projector 8 to the opposite surface of the board.

  In any of the embodiments described above, it is possible to write directly on educational software projected on the projector projection surface or data created by a personal computer from a remote location using a pointer or pen with a laser function mouse function. It is also possible to perform operations such as saving and recalling data.

  Although the present invention has been described in some detail with respect to its most preferred embodiments, it will be apparent that a wide variety of different embodiments can be constructed without departing from the spirit and scope of the invention, the invention being defined by the appended claims.
