Description

  The present invention relates to an exhibition case, and in particular, the light transmittance of a plate material surrounding the exhibition space for storing the exhibition, and the color, illuminance, direction, and light of the light that illuminates the exhibition from below the exhibition space. The present invention relates to an exhibition case that variously changes sound information such as music from a sound source playback device provided below.

  Various display cases are used to display archaeological and historical items and arts and crafts in museums and art galleries, and to display products in stores and exhibition halls. When an exhibit is a product, it is necessary to develop an exhibition strategy that enhances the image of the product and motivates purchasing. Therefore, the shape and function of the display case are devised. How to illuminate the exhibit is an important factor, but a technique for preventing the light source and the wiring from entering the view of the person viewing the exhibit at the same time as the exhibit is disclosed. For example, Patent Document 1 discloses a technique of illuminating an exhibit by providing a light reflector on the ceiling plate of an exhibition case and reflecting the light projected from the bottom of the exhibition space with the reflector. This technique is excellent in that the lighting fixtures and wiring are not exposed in the exhibition space, but there is a problem that the field of view is blocked when viewing the exhibit from above because the reflector is attached to the ceiling panel. Moreover, there is no technical idea to change the illumination.

Patent Document 2 discloses a technique in which a part of a transparent panel surrounding an exhibition space is configured by a liquid crystal display, and an explanation of the exhibit is displayed on the display. However, this technique has the effect of giving knowledge about exhibits in museums and the like, but it does not have the effect of sensuously purchasing goods.

As shown in FIG. 1, the display case 1 includes an exhibit storage unit 2 that forms an exhibition space for storing exhibits, and a support unit 3 that supports the exhibit storage unit 2. In order to put an exhibit (not shown) in and out of the exhibit storage unit 2, the exhibit storage unit 2 and the support unit 3 are separable.

FIG. 2 is a perspective view showing a state in which the exhibit storage portion 2 and the support portion 3 of the display case 1 are separated, and FIG. 3 is an exploded perspective view of the exhibit storage portion 2.
As shown in FIGS. 2 and 3, the exhibit storage unit 2 includes a frame body 4, a transparent upper plate 5 and three side plates (a front plate 6, a left side plate 7, and a right side plate 8). As a whole, it is a box shape in which the bottom 9 is opened. The frame 4 includes a back plate 10, a bottom frame portion 11 formed in a band shape surrounding the bottom portion 9 in a U shape, and a back frame portion 12 formed in a band shape surrounding the back plate 10 in a U shape. .
As the transparent plate material, a transparent plastic plate, for example, an acrylic plate is used, but a plastic plate of another material or a glass plate may be used.

Visible light transmittance is controlled by controlling the applied voltage on the surface of the transparent plate (upper surface plate 5, front surface plate 6, left side surface plate 7, and right side surface plate 8) on the inner side of the exhibit storage unit 2. A controllable liquid crystal plate is stacked to form a transmittance variable plate as a composite plate. The top plate 5 and the front plate 6 are stacked with three liquid crystal plates each of which can be individually controlled by being divided into three in the front-rear direction and the vertical direction. On the other hand, one liquid crystal plate is superimposed on each of the left side plate 7 and the right side plate 8. Of course, how to divide a single plate to control the transmittance or not to divide varies depending on what effect the designer wants. It is only an example.
The liquid crystal plate is formed by forming a transparent electrode on one surface of a glass plate, a plastic plate, etc., facing the transparent electrode forming surface and sandwiching the liquid crystal between them. In this embodiment, the liquid crystal is sandwiched between flexible plastic sheets. A plastic liquid crystal plate, for example, a Japanese plate glass UMU sheet (trade name) is used.

  FIG. 4 shows a method of superimposing the liquid crystal plate 13 on the transparent plate 14. A liquid crystal mounting portion 16 having grooves 15 formed at both ends of the transparent plate is provided, and the liquid crystal plate 13 is inserted into the grooves 15. In FIG. 4, the transparent plate member 14 and the liquid crystal attachment portion 16 are integrally molded. However, the liquid crystal attachment portion 16 may be formed in a rod shape and attached to the transparent plate member 14.

FIG. 5 is a perspective view of the exhibit storage unit 2 as viewed obliquely from behind and below.
When the liquid crystal plate 13 is a Japanese plate glass UMU sheet (trade name), a terminal 17 connected to a transparent electrode for applying a voltage to the liquid crystal is provided on one side of the liquid crystal plate 13. The wiring 18 is integrated in a connector 19 attached to the back plate 10 along the frame 4. The frame 4 is preferably formed of an opaque plate so that the wiring 18 and the connector 19 of the liquid crystal plate 13 are not visible from the outside of the exhibit storage unit 2.

As shown in FIG. 2, a light emitter 20 that illuminates the exhibit storage unit is provided on the upper surface of the support unit 3. The illuminant can be any kind of incandescent lamp, but it does not rise in temperature, has directivity, can easily control the color, illuminance, direction, etc. of light, and can produce a wide range of lighting effects. A light emitting diode (Light Emitting Diode) is preferable. In FIG. 2, five commercially available LED units in which LEDs of three colors are combined to form a unit are provided, but various arrangements may be possible depending on what lighting effect is aimed for. Moreover, you may combine light-emitting bodies other than LED.
The power source of the light emitter is inside the support 3 and is controlled by a control device described later.

The light emitter 20 is a light emitting element composed of a rectangular frame-shaped light emitter storage frame 21 formed of an opaque plate, and a light emitter storage upper plate 22 held by the light emitter storage frame and formed of a transparent plate. It is stored in the body storage unit 23. On the rear side of the luminous body storage frame 22, a connector 24 is installed at a position corresponding to the connector 19 attached to the frame 4, and when the exhibit storage unit 2 is placed on the support unit 3, the connectors 19 and 24 are Connected. In addition, the wiring (not shown) from the connector-24 is connected to a control device described later.
A back cover plate 25 is provided upright on the rear portion of the support portion 3.

The exhibits are displayed on the light emitter storage unit 23 or are displayed on a display stand (not shown). After the exhibit is placed on the light emitter storage unit 20 or the display stand, the exhibit storage unit 2 is placed on the support unit 3.
The light emitter housing frame 21 formed of an opaque material conceals the wiring 18 of the liquid crystal plate 13 provided along the inner surface of the bottom frame portion 11 of the frame 4. That is, the light emitter storage frame 21 is installed so as to be disposed inside the bottom frame 11 with a predetermined gap (a gap in which the wiring 18 can be stored), and the wiring 18 is disposed between the bottom frame portion 11 and the light emitter storage frame. It is stored in the gap of 20. Therefore, it is preferable that the upper surfaces of the light emitter storage frame 21 and the bottom frame portion 11 of the frame 4 have substantially the same height.
The back cover plate 25 of the support 3 covers and protects the wiring 18 and the connectors 19 and 24 of the liquid crystal plate 13 provided on the back surface of the back plate 10.
As described above, the connector 19 attached to the frame 4 and the connector 24 attached to the light emitter housing 21 are connected.

Speakers 26 are provided on the left and right side surfaces of the support unit 3 as sound source playback devices, and various sound information including music is played back in stereo. Depending on the situation of the exhibition, it may be inappropriate to use a speaker. In such a case, the sound source reproducing device may be a headphone.
Inside the support unit 3 is provided a control device (not shown) for controlling sound information reproduced by the speaker 26, a voltage applied to the liquid crystal plate 13, and a voltage applied to the light emitter 20 (LED). When a memory card is used as a storage medium for storing a control program and control data of the control device, a memory card reader (not shown) is provided, and a card slot 27 is provided on the support unit 3 on the front surface. .
It is preferable that all the side surfaces of the support portion 3 are formed of an opaque material so that the devices inside the support portion 3 cannot be seen from the outside.
In the above embodiment, in order to conceal the wiring portion 18 of the liquid crystal plate 13, the exhibit storage portion 2 is configured by using the frame 4 made of an opaque material. Depending on the installation position of the body 20, the frame body 4 may not be used, and only the side plate (including the back plate 10) and the top plate may be used.

  Next, a method for controlling the liquid crystal plate, the light emitter, and the sound source reproducing device will be described. In this embodiment, control data for controlling the blinking, illuminance, direction, and transmittance of the liquid crystal plate in synchronism with music suitable for the exhibit is taken into the control device, and the liquid crystal plate and light emitter are based on this. The sound source playback device (speaker) is driven synchronously.

FIG. 6 is a basic configuration diagram of the control device.
As shown in FIG. 6, the control data for controlling the transmittance of the liquid crystal plate and the blinking of the light emitting body, the illuminance, and the direction in synchronization with the music suitable for the exhibit, and based on this control data, the liquid crystal plate, the light emitting body, Control data fetching means 31 for fetching a control program for controlling the sound source reproduction device, storage means 32 for storing the fetched control data and control program, liquid crystal plate control data for controlling the liquid crystal plate driver 34 by the control data and the control program, It comprises light emitter control data for controlling the light emitter driver 35 and synchronization control means 33 for generating sound source reproduction device control data for controlling the amplifier 36 for driving the sound source reproduction device.
When the sound source playback device control data is compressed data, a decoder is further provided.

  The liquid crystal plate driver 34, the light emitter driver 35, and the amplifier 36 are designated so as to be compatible with the liquid crystal plate 13, the light emitter 20, and the sound source reproduction device 26 provided in the display case 1, respectively. The liquid crystal plate control data, the light emitter control data, and the sound source reproduction device control generated by the synchronization control means 33 are suitable for the liquid crystal plate driver 34, the light emitter driver 35, and the amplifier 36.

FIG. 7 is a block diagram showing the configuration of the control data generating means for generating control data.
As shown in FIG. 7, the control data generating means 37 includes a sound source data capturing means 38 for capturing music suitable for image enhancement of the exhibit, a transmittance of the liquid crystal plate 13 and a light emitter in synchronization with the timeline of the captured music. The synchronization control editing means 39 for generating the control data by inputting how to operate 20 and the control program for driving the liquid crystal plate 13, the light emitter 20 and the sound source reproduction device 26 based on the control data are stored in the storage medium. Control data writing means 40 for writing.
The sound source (sound information) captured by the sound source data capturing means 38 is not limited to music, but may be natural sounds such as wind and water, artificial synthesized sounds, animal voices, and the like.

A personal computer (PC) can be used as the control device. In that case, the control data generation means 37 is also included in the control device, and all control is instructed from the keyboard of the PC. However, it is not preferable to provide each display case with a PC because it increases the manufacturing cost of the display case.
Therefore, it is preferable to provide a data reading device for a recording medium storing control data as the control data fetching means 31 of the control device. In this embodiment, a memory card reader is provided. In that case, the control data writing means 40 of the control data generating means 37 is a memory card writer.
A memory card writer is connected to a PC provided separately from the display case, and control data is written to the memory card. The memory card in which the control data is written is inserted into the memory card reader of the control device, and the control data is captured.
In the present embodiment, the control data and the control program are read by the control data fetching means 31 of the control device, but the control program may be stored in the storage means 32 in advance.
Further, in the above-described embodiment, the control in which the liquid crystal plate and the light emitter are driven simply in synchronization with music is shown, but it goes without saying that various complicated controls are possible.

  It is also possible to provide a human sensor in the display case so that the music, the liquid crystal plate and the light emitter are driven only when the human sensor is activated. In that case, the control device stands by in the standby mode, and the auto start mode is set.

The form of the display case in the above-mentioned embodiments varies within the scope of the technical idea of the present invention depending on the transparent plate used, the material of the liquid crystal plate, the position where the electrode is taken out, the position where the light emitter is installed, the control method, etc. Needless to say, the design can be changed.
8 and 9 are perspective views showing other forms of the display case. By using a liquid crystal plate made of a plastic sheet, it is possible to have a curved shape or a shape that does not use an opaque plate on the back.
