The projected images of murmuring and rural scenes are shaken, and it is possible to create a soothing impression that you can feel as if you are watching the scenery and colors that are subtly swayed by the wind through the lace curtains. Alternatively, similar effects can be obtained by projecting light of various colors from the light source unit 18 provided on the lower beam 4.

Next, an automatic control system that is an automatic control unit for the amount of air discharged from the screen 1 to the back side of the screen 1 will be described.
As shown in FIG. 12, the automatic control system is generally supplied with air from a blower 24 that is an air source, and any one of various fragrances 25 passes through one of valves f, g, h,. After being mixed and the air volume adjusted by the flow rate adjusting valve 26, the back side of the screen 1 from one or more locations of the air outlets A, B, C, D, E through the valves a, b, c, d, e It is comprised so that it may discharge.

In this automatic control system, in order to change the amount of air discharged from each of the air outlets A, B, C, D, E with time, various control patterns and types of fragrances are stored in the system in advance. This is configured to select and operate.
An example of this control pattern is shown in FIG. 13 (a). In this figure, the vertical axis represents the air discharge amount Q, the horizontal axis represents time T, and the discharge amount Q changes with the passage of time. X, Y, and Z in the figure are change patterns of the discharge amount Q, and indicate that these patterns are continuously and automatically controlled. In this case, pattern X stops rapidly after the discharge amount gradually increases with time, pattern Y gradually decreases after discharge amount gradually increases with time, and pattern Z has a constant discharge amount. It shows that there is a gradual decrease over time without changing time.

When executing the above pattern, for example, the air blowing of the pattern shown in FIG. 13 (a) is assigned to each of the air outlets A, B, C, D, E as shown in FIG. 13 (b). In this case, for example, the X pattern is divided into X1 to X5, X1 is assigned to the air outlet A, X2 is assigned to the air outlet B,... Sequentially, Y is divided into Y1, Y2 and Y1 Distributes Y2 to the air outlets D, E to the air outlets A, B, C, divides Z into Z1, Z2, and Z3, Z1 to the air outlet A, Z2 to the air outlet B, and Z3 to the air outlet C The air is distributed in order and blown.

Next, an example of a series of operations until the air is discharged from the system for automatically controlling the screen device of the present invention will be described based on the circuit diagram shown in FIG.

1. First, when “POWER-ON” is pressed, power is supplied from the AC power supply.
2. Next, the “air flow pattern switching switch B” is pressed to select and set a pre-stored air flow pattern. In this case, the start / stop switch A may be either ON or OFF. In other words, when it is turned on, air blowing can be operated, but the air flow, time, fragrance, etc. can be set even during operation.
4. After completing the setting of the air flow rate pattern, press the “fragrance pattern changeover switch C” to select the type of the fragrance stored in advance, and set the supply amount, supply time, and the like.
5. Next, press “illumination pattern changeover switch D” to set the illumination type, illuminance, lighting time, etc.
6. Next, press “Image Pattern Change Switch E” to set the image type.
7. When all settings are complete, turn on “Start / Stop Switch A”.

Automatic control starts with the above settings, valves a, b, c, d, e are opened, a valve for supplying the selected fragrance, for example, f is opened, air is supplied from an air source (blower), and fragrance or Air is discharged from the air outlet through the valves a, b, c, d, and e. In addition, lighting and images set in accordance with this are also displayed.
The above can also be operated by remote control.

Lighting and images can be projected before the “Start / Stop Switch” is turned on. You can also change the blast volume and fragrance even after turning on the "Start / Stop Switch". For the supply of the fragrance, instead of the configuration in which the fragrance circuit is provided in the air circuit in the present embodiment and discharged together with the air blowing, a discharge port dedicated to the fragrance may be provided separately from the air circuit. In this case, only the fragrance can be released without blowing.

Moreover, the types of patterns such as the amount of blown air and fragrance described above are not limited to the above. Moreover, you may operate only one part, without operating all of ventilation, a fragrance | flavor, illumination, and an image. For example, when only air blow, fragrance, and illumination are activated and the image is not activated, the image can be set not to be projected by selecting the image OFF when selecting the image pattern.

By the above automatic control system, it becomes possible to repeatedly blow the selected pattern and / or supply the fragrance for a predetermined time and continuously. Moreover, since the adjustment of the blast volume is patterned, the labor of adjustment can be saved. Since the amount of air to be discharged is different for each air outlet, various fluctuations occur in each part of the screen. This reproduces the scenery of grasslands and forests that fluctuate due to changes in the cold in nature, and provides an effective healing effect.
