DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display device that can sequentially display a large number of display boards by circulating them between a display position and a hidden position.

[Prior Art] Such a display device has already been proposed by the present applicant, and is disclosed in, for example, Japanese Patent Laid-Open No. 146478/1983. Since the present invention can be suitably implemented in this manner, the prior art will first be explained with reference to FIGS. 1 to 3.

In FIGS. 1 to 3, the display device is equipped with a box indicated by 1, and a window hole is formed in the front side of the box, and a transparent plate 2 is fitted into the window hole. Four sprockets 3, 4, 5, and 6 are provided on each side of this box 1, and a chain 7 is stretched across these sprockets 3, 4, 5, and 6 in a rectangular manner. This chain 7
A gripper 10 is attached to each end of the support rod 9 supporting the display panel 8. Also, on both sides inside box 1 are sprockets 5 at the rear of the upper part.
A display board guide member 11 is provided which is inclined downward from the upper front sprocket 3 from just below the display board guide member 11. Near the end of this guide member 11 is a display board delivery vehicle 13 equipped with a plurality of arms 12. is provided. The chain 7 is intermittently rotated counterclockwise in FIG. 2 by the chain drive motor 14, and although not shown, the control mechanism is used to control the power switch and the display board 8.
A sound generator or the like is provided to explain the content.

When the motor 14 is driven during operation, the chain 7
moves in the direction of the arrow, and the display board gripped by the gripper 10 attached to the chain 7 also moves upward from the lower position 8', and when the gripper 10 passes over the sprocket 5, it is gripped by the gripper 10. The display board 8 that had been placed on the display board 8 is transferred to the guide members 11 provided on both sides. On the other hand, the display board 8 that was displayed for a predetermined time

However, such a known display device may be difficult to see depending on its installation location. For this purpose, for example, Utility Model Application Publication No. 55-8939 and
In Publication No. 16177, a technology was developed in which a light source was provided on the back of an advertisement to make the advertisement clearly visible. However, in these known techniques, the light source is located far away from the display board, making the display board unsightly. Especially in a circulating type display device, when the light source is provided behind the display board at the display position, the light source is not supported by the guiding member. The light source gets in the way when moving the display board to the display position. Furthermore, if a guiding member is not provided after the display board as in the above-mentioned Japanese Patent Application Laid-open No. 56-16177, the distance that the next display board must move when moving the display board becomes longer. , since it takes time,
It's inconvenient.

[Problems to be Solved] Accordingly, it is an object of the present invention to provide a display device that emits light only from the display board at the display position so that it is very clearly noticeable and highly effective in advertising.

[Means for Solving the Problems] According to the present invention, in a display device in which a large number of display boards are circulated between a display position and a concealment position to sequentially display a display, a plurality of light emitting panels that emit light when energized are provided. Means is provided on the display board, a conductive member electrically connected to the light emitting means is provided at the end of the supporting member of the display board, and a power source is provided at the end of the guiding member of the display board for guiding the display board to the display position. A connected conductive portion is provided.

[Description of the effects of the invention] Therefore, since the display board at the display position is located at the end of the guiding member, the current from the power source flows to the end of the support member through the conductive part provided at that position. The light passes through the provided conductive member and flows to the light emitting means of the display board which is electrically connected to the conductive member, and as a result, the light emitting means emits light. Since the light emitting means is provided on the display board, it is bright and easy to attract attention. Therefore, advertising effectiveness can be improved. It is especially effective at night when it is dark. Furthermore, since the display board emits light only when it is in the display position, it is energy efficient. Moreover, since the display board is provided with a light emitting means, the display board circulation work can be carried out in the same manner as before. The entire display board may be made to emit light, or only a specific part, such as a line in a picture, may be made to emit light, as in the case of a neon sign. For example, a light bulb may be used as the light emitting means for the display board, and when the display board is at the display position, electricity is applied to light the light bulb and cause the display board to emit light.

[Examples] Examples of the present invention will be described below with reference to the drawings.

Then, as described above, when the delivery wheel 13 is rotated by the gripper 10 and the display plate support rod 9 is separated from the conductive plate 21, the light bulb 16 is turned off.

FIG. 6 shows a second embodiment of the present invention, in which characters or pictures are drawn using color light bulbs. Reference numeral 22 denotes a light bulb support plate which is made up of three insulating plates, such as synthetic resin plates that do not undergo deformation due to heat, separated by an interval, and 23 and 23' are copper plates housed within each plate of the light bulb support plate 22. A conductive plate 16 is a color light bulb attached to the surface of the light bulb support plate 22 to form letters and pictures, and this light bulb 16 is connected to two conductive plates 23 and 23'. One of the conductive plates 23 is connected to the conductive cap 20 which is one of the conductive members of the support rod 9 of the display board 8, and the other conductive plate 23' is connected to the conductive cap 20 of the support rod 9 of the display board 8. It is connected to a conductive cap 20 which is a member.
