[0001]

[Industrial applications]

 The present invention relates to a general-purpose display device, and more particularly, to a general-purpose display device that can give a strong impression by giving a surprising visual change to a customer or the like.

[0002]

[Prior art]

 Display devices are used in various stores as a customer attraction medium that attracts attention, and various types of display devices have been proposed, from simple to complex.

In such a display device, a motor is fixed via a motor stand fixed to the side of the housing, and a smoke type polarizing plate is attached to the rotating shaft of the motor, and in front of this polarizing plate. In some cases, a diffuser plate, a polarizing plate, and a light-shielding plate with a see-through part are arranged in sequence, and in this case, the character display surface formed by the see-through part of the light-shielding plate is rotated by rotating the smoke-type polarizing plate. Some have made changes so that they can draw the attention of customers.

[0004]

[Problems to be solved by the device]

 By the way, the above-mentioned display device using the rotating polarizing plate can also exert a corresponding customer attraction force.

However, since the motor in the above-mentioned conventional device is fixed to the side of the housing via the motor stand, the thickness of the device itself inevitably becomes large, and it becomes large and heavy. However, there was an inconvenience that transportation costs and product costs increased. In addition, the changes that develop on the character display surface are limited to the repetition of light and dark patterns that are not so clear, which makes it less surprising and quickly tired of seeing, and the attention immediately drops. There was something wrong.

[0006]

[Means for Solving the Problems]

 The present invention has been made in view of the above problems of the conventional device. Among them, the structural feature of the invention according to claim 1 is that the light source and the light source disposed in front of the light source are A diffusing plate for diffusing light, a motor arranged via the diffusing plate, and a first smoke polarizing plate arranged on the front face of the diffusing plate so as to be freely rotatable via a rotation shaft of the motor. , A transparent plate that can be positioned in front of the first smoke polarizing plate to form light interference fringes, a second smoke polarizing plate disposed in front of the transparent plate, and a front surface of the second smoke polarizing plate. It is formed by a light-shielding plate with a see-through portion arranged.

In addition, the structural feature of the invention according to claim 2 is that a light source, a light diffusing plate that is disposed in front of the light source and diffuses light from the light source, and a light diffusing plate that is disposed via the light diffusing plate. Motor, a smoke polarizing plate disposed on the front surface of the diffuser plate so as to be freely rotatable through the rotation shaft of the motor, a transparent plate disposed on the front surface of the smoke polarizing plate, and the transparent plate. Of the first colored polarizing plate disposed on the front surface of the first colored polarizing plate, the second colored polarizing plate disposed on the front surface of the first colored polarizing plate having different colors and different directions from each other, and the second colored polarizing plate of the second colored polarizing plate. It is formed with a light-shielding plate with a see-through portion arranged on the front surface.

[0008]

[Action]

 Therefore, according to the first aspect of the invention, the light from the light source is transmitted through the diffuser plate while being diffused, and is attached to the rotating shaft of the motor to be rotatable. To reach the smoked polarizing plate.

Since the first smoke polarizing plate is rotatable, its directionality can be changed in accordance with the rotation angle. The light reaches the transparent plate which is located on the front surface of the second polarizing plate, and the light passes through the transparent plate to form the interference fringes and reaches the second smoke polarizing plate disposed in front of the transparent plate. After passing through, it reaches the light shielding plate.

Therefore, the light from the light source is arranged so as to be freely rotatable, the first smoke polarizing plate, the transparent plate capable of forming interference fringes of light, and the first plate disposed on the front surface thereof. By passing through the 2nd smoke polarizing plate, the light shielding plate changes its shape while exhibiting the same color pattern as the rainbow color caused by the oil film spreading on the water surface under the relationship with the rotation speed of the first smoke polarizing plate. It can be seen through the see-through part.

According to the second aspect of the invention, the light from the light source is transmitted through the light diffusing plate while passing through the light diffusing plate and is attached to the rotation shaft of the motor to be rotatable. It reaches the mork polarizing plate.

Since the smoke polarizing plate is rotatable, its directionality can be changed in accordance with the rotation angle, and while the directionality changes in this way, the transparent plate disposed on the front surface thereof can be changed. The light that reaches the plate material, passes through the transparent plate material, and the light reaches the first colored polarizing plate disposed on the front surface of the plate, passes through the first colored polarizing plate, and then the second colored polarized light. It reaches through the plate to the light shield plate.

Therefore, the light from the light source is arranged so as to be freely rotatable, and includes a smoke polarizing plate, and a first colored polarizing plate and a second colored polarizing plate which are arranged with different directions. It is observed through the see-through part of the light-shielding plate that the color of the first colored polarizing plate itself and the color of the second colored polarizing plate itself alternately change depending on the rotation speed of the smoke polarizing plate. It will be possible.

After that, the light reaches the light shielding plate 26 via the second colored polarizing plate 25.

Therefore, the light from the light source 11 is arranged so as to be freely rotatable, and the smoke polarizing plate 22 and the first colored polarizing plate 24 and the second colored polarizing plate 24 which are arranged in different directions. By passing through the polarizing plate 25, if the color of the first colored polarizing plate 24 itself is green and the color of the second colored polarizing plate 25 itself is red in accordance with the rotation speed of the smoke polarizing plate 22, light shielding is performed. Through the transparent portion 27 of the plate 26, it is possible to visually observe that the color changes alternately.

Therefore, an automobile, a flower, a face with glasses, or the like is drawn on the light-shielding plate 26, and, for example, the headlight part of the car, the petals of the flower, the lens part of the glasses, or the lip part of the face. When the transparent portion 27 is used as the transparent portion 27, by changing the color of the transparent portion 27 alone, it is possible to exert a peculiar display effect which is rich in appeal to the entire figure drawn on the light shielding plate.

Further, the diffuser plate 12 according to claim 1 or claim 2, the motor 14 disposed via the diffuser plate 12, and the rotation shaft 15 of the motor 14 are arranged so as to freely rotate.
