DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of the refresh device of the present invention. This refreshing device includes a vibration stimulating device for giving a vibration stimulus to a user, a light stimulating device for giving a light stimulus, an air stimulating device for giving an air stimulus containing an aroma, and a sound stimulus. It is provided with a sound stimulating device and a control device for controlling each of the above devices. The configuration of each device will be described below.

First, the vibration stimulating device is constructed by incorporating the vibration stimulating means 2 in the chair 14. The chair 14 is of a reclining type in which the backrest portion 15 falls backward. A plurality of vibration stimulating means 2 are incorporated in the chair 14 so that, for example, when the user sits down, a comfortable vibration is given to the waist and legs. The vibration frequency of the vibration stimulating means 2 changes in a pattern of 1 / f fluctuation between 20 to 40 Hz, for example, and the magnitude (amplitude) of the vibration gradually decreases with time, and is detected by the relaxation degree detecting means. It is controlled by the degree of relaxation performed and guides the user to a relaxed state within a few minutes.
Here, the degree of relaxation detection means knows the activity of the autonomic nerve by, for example, mounting the sensor unit 1 at two points on the user's fingertip and measuring the skin electrical resistance (SRL) between the two points. , To estimate the degree of relaxation of the user.

Next, the structure of the optical stimulator will be described. A high illuminance lighting device 5 is attached to the head of the chair 14 described above. Further, a movable hood 4 that covers the user's head and blocks external light is attached to the head of the chair 14 so as to cover the lighting device 5. A light reflection plate 6 that diffuses light from the lighting fixture 5 to the face of the user is attached to the inside of the hood 4, and the light reflection plate 6 is approximately 10,000 at the position of the user's eyes.
A uniform illuminance of 0 lux is obtained. From the user's point of view, the inner wall of the hood 4 appears to be uniformly bright.

Next, the structure of the air stimulator will be described. Near the head of the chair 14, a blower opening 7 is arranged from the user's head to the neck to give a cold air stimulus. A blower 8 is housed in the lower portion of the chair 14, and cool air is guided to the air outlet 7 arranged on the head of the chair 14 via the air pipe 10 housed along the backrest portion 15. By changing the nozzle shape and the opening diameter of the blower opening 7, the blowing shape and strength of the cold air are temporally changed. An aroma generating unit 9 is provided in the middle of the air pipe 10, and raises the awakening level of the user by generating an arbitrary aroma.

Next, the structure of the sound stimulator will be described. In the sound stimulator, near the user's ear (for example, chair 1
4 headrest part) sound output part 1 like a speaker
1 is provided to generate a sound stimulus such as music or white noise that masks external sound during a relaxation period due to vibration stimulus.

Finally, the control device 12 is arranged, for example, in the lower part of the chair 14 and controls each of the stimulators in accordance with a preset time schedule. Specifically, when the user presses the start button of the operation unit 13, the illuminance of the photostimulation device is gradually reduced to darkness, and the sound stimulation device is operated to generate music for masking or white noise, After activating the relaxation device and relaxing the user for about 7 minutes, the illuminance of the photostimulation device is gradually raised this time, and after returning to the initial illuminance, it is blinked for several seconds, and the illuminance is further about 10,000 lux. In addition to raising the illuminance to a high illuminance, each device is operated so as to raise the arousal level of the user by activating the air stimulating device and applying the air stimulus for about 3 minutes.

The usage status of this embodiment will be described below. First, in the initial state, the illuminance of the photostimulator is about 5
It is set to 00 lux. The user attaches the sensor unit 1 of the relaxation degree detecting means to the fingertip, sits down on the reclining chair 14, and sets the initial value of the vibration intensity by the volume of the operation unit 13 of the control device 12. When the user presses the start button of the operation unit 13, the illuminance of the photostimulation device gradually decreases and becomes dark. The backrest portion 15 of the chair 14 falls down by about 180 degrees, and the user's waist and legs are subjected to vibration stimulation by the vibration stimulation means 2. The frequency of vibration is 20-40Hz in the initial state
Changes with the pattern of 1 / f fluctuation between
With the passage of time and as the user relaxes, the range of change narrows to around 30 Hz. On the other hand, the amplitude (strength) of the vibration changes with time,
It becomes weaker as the user relaxes. The degree of relaxation of the user is measured by the degree-of-relaxation detecting means at regular intervals (for example, every 3 seconds) based on the skin electrical resistance measured by the sensor unit 1. Further, masking sounds such as music and white noise are generated from the sound output unit 11 of the sound stimulator. As described above, the vibration stimulation by the vibration stimulation means 2 is appropriately controlled by the control device 12, so that the user is guided to the relaxed state within a few minutes, and the state is maintained for about 7 minutes. During this relaxing period, the user may be in a light sleep state. After the relaxation period of about 7 minutes has passed, the illuminance of the photostimulation device gradually rises, the brightness returns to the initial brightness after about 1 minute, and the blinking for 10 seconds causes the awakening level of the user to naturally increase. go. After that, the back portion 15 of the chair 14 rises up to about 90 degrees, and the illuminance of the light stimulus sharply rises to about 10000 lux. At the same time, from the head to the neck of the user, about 3 from the air outlet 7
Since the cold wind stimulus and the aroma stimulus are given for a minute, the arousal level of the user rises to such a degree that the user can immediately move to the next activity. Therefore, the user can relieve stress in a total of about 10 minutes, and can move on to the next work.
