Description

The present invention relates to a projector device and a production method using the projector device, and in particular, a projector device for production in which a moving image is projected onto a predetermined object at an event such as a wedding party, and an event using the projector device. About the production method to liven up.

In recent years, in facilities such as wedding reception halls and restaurants, services that produce images while projecting images with a projector have become widespread. For example, Japanese Patent No. 5919409 proposes a party production method in which a large number of beverage containers such as glasses are stacked in a tower shape, a screen is arranged around the container, and an image is projected on the screen. Japanese Patent Application Laid-Open No. 2018-101312 proposes a production method of projecting an animated three-dimensional image showing a cooking process of food and drink on a table in front of a customer who visits a restaurant with a projector.

In this way, at a facility such as a party venue or a restaurant, a great effect can be expected by performing an attraction that projects a moving image such as an animation on a table or a wall in front of the customer. However, in order to carry out such an effect, a projector is arranged in advance on the wall or ceiling of the facility, and wiring for providing electric power and image data to the projector is required. It takes a lot of time and cost.

On the other hand, Japanese Patent Application Laid-Open No. 2013-502606 proposes a table-integrated computer-controlled projector unit in which a projector is attached to the table as a means for projecting an image on the upper surface of the table, and the ceiling or wall of the facility. It is possible to realize the effect of projecting a moving image on the table in front of the customer while eliminating the trouble and cost of arranging the projector in advance and connecting the wiring.

However, in implementing this technology, although the labor and cost of arranging the projector in the facility is not required, it is necessary to construct a dedicated table equipped with a stand with a projector and a dedicated computer control system to some extent. In addition to the installation cost, it will be necessary to replace the table to install it in the existing facility. In addition, since the stand with an umbrella for hiding the projector stands in the center of the table, there is also a problem that the appearance is deteriorated.

Japanese Patent No. 5919409 Japanese Unexamined Patent Publication No. 2018-101312 Japanese Patent Application Laid-Open No. 2013-502606

The present invention is intended to solve the above-mentioned problems, and makes it possible to project a moving image onto an object at a predetermined event without requiring excessive labor and cost, and to obtain a large effect. The task is to do.

Therefore, the present invention includes a projector as a moving image projection means, a support arm that supports the projector downward above the table, and a mounting plate arranged on the table on which the object is placed, from above on the object. In a projector device that automatically projects a moving image, the support arm is erected with the base end side fixed at a predetermined position on the outer edge side of the mounting plate, and the mounting plate is a power supply means for supplying power. It is equipped with a control means for controlling the operation of the projector and a data input unit for inputting content data constituting the content to be projected, and a storage medium is connected or data is transmitted to the data input unit to input content data. By doing so, the feature is that the production is performed while projecting a moving image on the object.

In order to automatically project a moving image onto an object on the table, a means for supporting the projector downward and a control means for supplying power and moving image data to the projector in an appropriate state are required. If the projector is integrated with a projector, it will be a projector device with a certain size and weight, so a solid structure is required to support it above the object, and the projector device is supported. However, it becomes easy for the parties and viewers to notice the effect of the production. Therefore, as described above, by adopting a method in which elements other than the moving image projection means are provided on the mounting plate side on which the object is placed among such projector devices, those supported above the object can be made compact. Since it fits in and is difficult to recognize, it is easy to obtain a surprisingly large effect.

Further, in this projector device, the mounting plate is provided with a speaker, and by inputting content data having audio data in addition to the moving image data from the data input unit, it is linked to the projected contents of the moving image. If it is characterized by emitting sound, a larger effect can be obtained.

Further, in the above-mentioned projector device, the projector is supported by the support arm in a state where it can be rotated around the horizontal axis on the tip side of the support arm and can be fixed at a desired angle, and the projection direction thereof can be adjusted. If the feature is that the projector is supported at a position shifted from directly above the object, the video is projected in a positional relationship between the support arm and the projector so that they do not interfere with the production. Will be possible.

Furthermore, in the above-mentioned projector device, the mounting plate and / and the support arm are provided with a sensor for detecting the presence / / or movement of a surrounding person, and senses the presence / / or movement of a person. As a result, if it is characterized in that the projection of the moving image and / or the output of the sound are changed, the effect of the effect is further improved.

Then, the projector device equipped with the above-mentioned speaker is mounted on a table, a plate or a plate on which a plate is placed is placed on the mounting plate, and the content data is input to the data input unit to obtain a projector. If the production method is characterized in that the sound is emitted from the speaker while projecting a moving image on the upper surface of the plate or cake, a large production can be performed without any trouble while using relatively simple means at a predetermined event. The effect will be obtained.

According to the present invention in which the moving image projection means is supported above the object placed on the mounting plate and elements other than the moving image projection means of the projector device are provided on the mounting plate side, excessive labor is required in various events. While it is possible to project a moving image on an object at no cost, a large effect can be obtained.

It is a perspective view of the projector apparatus of the 2nd Embodiment in this invention. (A), (B), and (C) are plan views showing an example of the arrangement state of the projector device of FIG.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of the projector device 1A according to the first embodiment of the present invention, and FIG. 2 is a front view thereof. This projector device 1A is suitable as a means for producing a sound while projecting a moving image on the surface of a cake at a ceremony such as a cake cutting by a bride and groom at an event such as a wedding party.

Such a projector device 1A includes an ultra-small projector 4A, which is a moving image projection means having a downward projection hole opened on the lower surface side of a horizontally long rectangular casing, and an arch that supports the projector 4A in a downward state above the table. A mounting plate 2A having a shape and a disk-shaped mounting plate 2A for mounting an object on the upper surface while fixing and supporting the base end side of the support arm 5 is provided. It has a function to automatically project a moving image from above on the object placed on the table.

The support arm 5 is a pair of columns 50a, 50b made of straight tubular members that are vertically erected with the proximal end side fixed at the diagonal position on the outer edge side of the mounting plate 2A having a predetermined thickness. And a pair of arm bodies 51a and 51b made of tubular members that are inserted from the opening on the tip side of the columns 50a and 50b and bent laterally on the upper end side, and the tip of the bent horizontal portion of the arm bodies 51a and 51b. The projector 4A is supported in the meantime while the sides face each other.

As shown in the functional block diagram of FIG. 3, the disk-shaped mounting plate 2A includes a battery 25 as a power supply means for supplying power, a microcomputer, an amplifier, and the like inside the hollow disk-shaped casing 20. It is provided with a control unit 21 as a control means for performing various controls such as operation of the projector 4A, and a data input unit 28 for inputting content data constituting the contents projected by the projector 4A, other than the projector 4A. The biggest feature of the present invention is that all the elements of the projector device are arranged on the mounting plate 2A side.

That is, in order to automatically project a moving image onto an object on the table for the purpose of directing at an event, a means for supporting the projector downward and a control for supplying power and moving image data to the projector in an appropriate state. Means, etc. are required, but if these are integrated with the projector, it will be a projector device with a certain size and weight, so a solid structure is required to support this above the object. In addition to this, there is a problem that the projector device that is supported becomes conspicuous to the parties and viewers, which makes it easier to recognize the color of the production.

Therefore, in the present invention, among the above-mentioned projector devices, an element other than the projector, which is a moving image projection means, is provided on the mounting plate side on which the object is placed, so that the projector device is supported above the object. Since only a small projector is used, it is possible to secure a state in which it is difficult to recognize that a moving image is being projected using the projector, so that a large effect that is unexpected for the parties and viewers can be obtained.

As shown in FIG. 1, the data input unit 28 built in the mounting plate 2A has an SD card input slot, an AV connection terminal, and the like exposed on the peripheral surface side of the mounting plate 2A. , Content data can be easily input from the outside. Therefore, the content data can be easily transmitted by simply inserting the SD card, which is a storage medium for storing the content data, into the slot for the SD card, or connecting the connection cable extended from the PC or the like to the AV connection terminal and transmitting the data. Is input to automatically produce an effect while projecting a moving image on an object mounted on the mounting plate 2A.

Further, the mounting plate 2A is provided with speakers 26a and 26b in a state of being open on the peripheral surface of the casing 20, and by inputting content data having audio data in addition to the moving image data, the moving image can be projected. The fact that voice can be output while interlocking is also an important feature of this embodiment, which makes it possible to carry out an attraction that emits sound related to the content of the video while projecting the video on the object. Therefore, a larger effect can be expected.

Further, on the mounting plate 2A, an operating means 23 having an operating means such as a power switch for turning on / off the device, a knob for adjusting the brightness of the image, and a knob for adjusting the volume is arranged around the casing 20. It is provided so that it is exposed on the surface, and various operations can be performed manually. In addition to this, a wireless communication means 22 using a short-range communication method such as Bluetooth (registered trademark) is also built-in so that the device can be remotely operated while using a portable wireless communication means such as a smartphone. It has become.

By wirelessly inputting the content data from a smartphone, a PC, or the like that stores the content data via the wireless communication means 22 described above, it is possible to perform the production while demonstrating the content of the content on the projector device 1A. In this case, the wireless communication means 22 and the data input unit 28 are integrated to form a data input unit. Further, the above-mentioned operating means 23 is also provided with a charging terminal for supplying electric power to the battery 25, which is a secondary battery, to charge the battery 25.

FIG. 4 shows a state in which an example of the effect method using the projector device 1A described above is implemented. In this example, at the cake sword ceremony by the bride and groom at the wedding party, the projector device 1A is mounted on the main table, and the plate 90 on which the cake 80 is placed is placed on the mounting plate 2A. The upper surface of the cake 80 is in a flat state in which no decoration is placed on the plain cream in order to make it easier to capture a moving image.

An SD card storing content data for production is inserted and connected in advance to the data input unit 28, and the production person wirelessly controls the control unit 21 via the wireless communication means 22 while operating a smartphone or the like. By sending a command to the projector 4A, while projecting a moving image on the upper surface of the cake 80, the speakers 26a and 26b emit sound to liven up the cake cutting ceremony.

As described above, at an event such as a wedding party, an excellent effect can be easily executed while using a means having a relatively simple configuration such as the projector device 1A of the present embodiment. The projector 4A supported above the projector 4A has a battery 25, a control unit 21, a data input unit 28, and a speaker in the mounting plate 2A via a power supply wiring / data transmission wiring (not shown) inserted through the inside of the support arm 5. Since it is connected to 26a and 26b, it fits in an extremely compact size, so it does not look like it is being projected by a projector from above the object to the parties and viewers, which is quite surprising. A large effect will be obtained.

The projector 4A described above is supported in a state where it can be rotated around the horizontal axis on the tip side of the arm bodies 51a and 51b and can be fixed at a desired angle, and its projection direction can be adjusted. Therefore, while supporting the projector 4A at a position shifted from directly above the object, the support arm 5 and the projector 4A are positioned so as not to interfere with the production, and the projection position is set diagonally downward. It is also possible to adjust. Further, the arm bodies 51a and 51b of the support arm 5 are inserted into the columns 50a and 50b in a state where they can be expanded and contracted in the vertical direction, and after adjusting to an appropriate height, they are fixed by the fixing screws 55a and 55b. Can be done.

FIG. 5 shows the projector device 1B according to the second embodiment of the present invention. In this example, the support arm 6 that supports the projector 4B is not an arch type but a cantilever type consisting of only one support column 60 and an arm body 61 inserted therein, and the first described above. Parts such as the battery, the control unit, the speaker 36, and the data input unit 38, which are built in the mounting table 2A in the embodiment, are not built in the mounting table 2B, but are built in the casing 30 attached to the mounting table 2B. It is characterized by the fact that it is done.

The support arm 6 is supported by the tip side, although it is common with the projector device 1A in that the arm body 61 inserted in the support column 60 can be expanded and contracted up and down and the tip side thereof is bent horizontally. In the projector 4B, the tip side of the arm body 61 can be expanded and contracted in the horizontal direction and can be rotated around the horizontal axis, and can be fixed at each position and angle. Therefore, the horizontal position and the axial direction of the projector 4B The angle of is adjustable. Further, since the projector 4B is supported by the arm body 61, it can rotate in the axial direction in which the projector 4B is supported. Therefore, the projection position and projection direction of the projector 4A can be adjusted in various ways.

Further, the casing 30 that supports and fixes the base end side of the support column 60 while incorporating various parts is provided in a state of being mounted on the slide plate 31 inserted on the end edge side of the mounting plate 2B. The slide plate 31 can be expanded and contracted and fixed in position while sliding in a predetermined range along the centrifugal direction of the mounting plate 2B, and the casing 30, the support arm 6, and the projector 4B are integrated. , It can be separated by pulling it out from the mounting plate 2B. Therefore, in addition to being able to easily adjust the projection position of the projector 4B while matching the size and shape of the object to be mounted on the mounting plate 2B, it is convenient for transportation and storage if the slide plate 31 is removed from the mounting plate 2B. become.

FIG. 6 shows an example of the usage state of the projector device 1B in a plan view. As described above, the projector device 1B supports the projector 4B on the tip end side of the cantilever support arm 6, and rotates in the axial direction (vertical axis in the figure) in which the projector 4B is supported. It is possible and can be fixed at the rotated angle position.

Therefore, FIGS. 6A, 6B, and 6C are shown when adjusting the positions of the casing 30 and the support arm 6 so as not to get in the way, depending on the contents of the ceremony and attraction to be executed and the situation of the venue. As described above, the orientation of the moving image projected by the projector 4B around the vertical axis can be adjusted while rotating the projector 4B so that the orientation is always constant with respect to the front surface.

It should be noted that, in common with the projector device 1B of the present embodiment and the projector device 1A described above, the rotation and stop of the angle adjustment around the horizontal axis of the projectors 4A and 4B supported by the support arms 5 and 6 are performed. A driving means such as a step motor for performing this may be built in the support arms 5 and 6, and may be remotely executed by operating a smartphone or the like via wireless communication means. As a result, for example, if a moving image is projected on an object placed on the mounting plates 2A and 2B, and then the projectors 4A and 4B are rotated around the horizontal axis and projected on a wall or the like while being turned sideways, it is easy for the viewer to see. It is also possible to project a moving image at a position.

Further, in common with the projector devices 1A and 1B described above, the mounting plates 2A, 2B and / and the support arms 5 and 6 are provided with sensors for detecting the presence or / or movement of a person around them. By sensing the presence and / or movement, the projection of the moving image and / and the output of the sound may be changed, which can surprise the parties and the viewers and exert a more excellent effect. Will be.

As described above, in various events, the present invention has made it possible to project a moving image onto an object without requiring excessive labor and cost, and at the same time, a large effect can be obtained.
