Description

[Detailed explanation of the idea] [Industrial application field]

The present invention relates to a display device used for in-store advertisements and the like.

[Summary of the idea]

In the present invention, when light is projected from behind the display board and a pattern provided between them is projected on the display board,
This is a display device in which a required portion of the above-mentioned pattern is depicted on a rotating member and a transparent portion of a rotating member.

[Conventional technology]

Known examples of this type of display device include a rotating display member with a spiral pattern placed at the front of a barber shop, and a display device in which a pattern repeatedly appears and disappears on a display board by blinking light. In addition, there are also designs that move.

[Problem that the idea aims to solve]

The problem here is that the above-mentioned rotating display members and flashing symbols are extremely common and do not attract attention, and those with moving symbols are quite complex and large for this purpose. A large-scale organization is required. The present invention was developed based on the above-mentioned circumstances, and has a relatively simple structure that gives rotating and oscillating motion to the design, improves the display effect on the display board, and makes it sufficiently noticeable. It is an object of the present invention to provide an improved light projection type display device.

[Means to solve the problem]

Therefore, in the present invention, in a device that projects light from behind a display board to project a pattern provided therebetween on the display board, a rotating member includes a transparent portion depicting a desired part of the pattern; The apparatus includes a motor that drives the rotating member, and a rotating member that swings in conjunction with the rotating member and includes a transparent portion depicting other required portions of the pattern. Further, in this case, it is preferable to include a light transmission regulating member provided with light transmission windows corresponding to the light transmission portions of the rotating member and the rotating member. By means of the slit provided in the rotating member and the light-transmitting window provided in the light-transmitting regulating member, a blinking pattern portion corresponding to the light-transmitting window can be formed on the display board. Further, a mirror surface facing the display board is formed in the non-transparent part of the light transmission regulating member, and a half mirror member is disposed between the display board and the light transmission regulating member, and the half mirror member In addition, it is also possible to draw the part of the pattern to be displayed on the display board.

【Example】

Hereinafter, one embodiment of the present invention will be specifically described with reference to the drawings. In the figure, reference numeral 1 is a translucent display board of a display device fitted into the front of the case 2, and in the embodiment shown in FIG.
Parts A and B of the design of the characters ``Pioneer'' and ``Pioneer'' are depicted. In addition, a light source 3 such as a fluorescent light is disposed at the rear to project light toward the display panel 1. Further, between the light source 3 and the display panel 1, a disc-shaped rotating member 4 is rotatably supported by suitable support means, and an output shaft of a motor 5 is connected to a gear 4a formed on the outer periphery of the disc-shaped rotating member 4. A pinion 5a provided on the shaft is engaged with the pinion 5a. The rotating member 4 is provided with a circular transparent portion 4b near its center of rotation, and this portion is filled with several types of cellophane, paraffin, etc. to obtain a color that mimics the surface gloss of a laser disc. Translucent colored pieces 6 are arranged radially. Furthermore, the rotating member 4 is provided with a plurality of slits 4c located outward from the transparent portion 4b and extending in the radial direction. Further, a disc-shaped rotating member 7 is provided alongside the rotating member 4, and this also includes, for example, a roller 8.
It is rotatably supported by support means consisting of a, 8b, and 8c, and a swinging arm 7a provided on the rotating member 7 rolls into contact with a cam 9 attached to the adjacent rotating member 4. has been done. In order to maintain this rolling contact state, the swing arm 7a is resiliently supported by a spring 10. The rotating member 7
is composed of a transparent portion 7b as a whole,
A pattern 11 of Ohm is depicted there. Further, a light transmission regulating member 12 is disposed between the rotating member 4 and the rotating member 7 and the display panel 1. The light transmission regulating member 12 includes a circular light transmission window 12 corresponding to the light transmission portion 4b of the rotation member 4.
a, and a transparent portion 7 of the rotating member 7.
It is provided with a circular transparent window 12b corresponding to b. In particular, in this embodiment, the light transmission regulating member 12
is composed of a transparent plate, and the transparent windows 12a, 12b are
A transparent portion of the light transmission regulating member 12 is located in the region, and a sheet made of a non-transparent material is adhered to the other region to form a non-transparent portion 12c. In addition, a small star-shaped light-transmitting window 12d is provided outside the outer periphery of the light-transmitting window 12a by making a hole in the sheet. In such a configuration, the rotating member 4 is rotated by the drive of the motor 5, and the rotating member 7 is rotated in the forward and reverse directions (swinging) by the action of the swinging arm 7a of the cam 9. In the process of movement of the pattern formed by the colored pieces 6 on the light portion 4b and the pattern 11 on the transparent portion 7b, the light projected from the light source 3 illuminates the transparent window 1.
On the display board 1 via 2a and 12b, a pattern C in which Ohm is dancing while holding a microphone, and a pattern D in which a laser disk is rotating with its unique color luster are expressed. Further, the light transmitted through the slit 4c expresses the shape of the transparent window 12d on the display board 1 as a "blinking star" pattern E. In this way, with a relatively simple configuration, a display with movement in both rotation and rocking can be realized on the display board 1, and the display can catch people's attention. In the above embodiment, in order to effectively express the pattern D on the display board 1, a translucent film such as paraffin is applied to the transparent portion 4b provided with the colored pieces 6 to blur the outline. may be coated. Further, in the above embodiment, the rotating member 4 is connected to the motor 5.
Although the light source 3 is driven indirectly, if there is no problem with light projection from the light source 3, the output shaft of the motor 5 may be directly connected to the center of rotation. Also,
The rotating member 7 may also be supported by providing a shaft in the center thereof. Further, in the above embodiment, the case where the light-transmitting window 12a is circular is explained, but the light-transmitting window 12a is not limited to this example, and as shown in FIG. The laser disc is shown in the form of a disk, and can also be made to appear to be rotating on a flat surface. In the embodiment shown in FIG. 3, portions A and B of the character design are not drawn on the display board 1, but are depicted on a half mirror member 13 provided between the display board 1 and the light transmission regulating member 12. They are depicted as 14a and 14b. Further, in this embodiment, the non-light-transmitting portion 12c of the light-transmitting regulating member 12 is formed of a mirror surface facing toward the display panel 1. Because of this configuration, the half mirror member 13
The character designs 14a and 14b drawn on the display board 1 are drawn multiple times. Thereby, a three-dimensional effect of the display on the display board 1 can be obtained.

[Effects of the invention] As detailed above, the present invention has a relatively simple structure, gives rotational and oscillating motion to the design, and
The display effect on the display board is improved, and a display device that attracts people's attention is constructed. Further, by regulating the light-transmitting area, the pattern can be made to stand out, and a flashing effect can also be obtained. Furthermore, by employing a half mirror or the like, various variations can be obtained, such as forming a three-dimensional image on the design on the display board.
