The present invention aims to solve such problems, and each display board is easy to see, and
By having a structure in which some of the display panels can be easily replaced or a structure capable of displaying three or more types, a display device with high multi-screen display capability is provided.

[Means to solve the problem]

In order to achieve the above object, the display device of the present invention includes an endless drive member rotatably wound around a drive wheel fixed to a drive shaft and a driven wheel fixed to a driven shaft; A shaft portion pivotally attached to the driving member is provided at the end of the plate-shaped portion having display surfaces on both front and back surfaces, and a plurality of display plates arranged in a predetermined area of the driving member and the shaft portion are connected to each other. A first protrusion and a second protrusion protrudingly provided, and a first protrusion and a second protrusion disposed at either end of the rotation path of the driving member, the first protrusion and the second protrusion being slidably guided in a tilting prevention state. a first guide member having a cam that rotates, a second guide member that is disposed on the other of the two ends and has a cam that rotates half a time as the second protrusion is slidably guided; and a rotational movement of the drive member. It consists of a fixed display board placed inside the road.

Alternatively, instead of the fixed display board disposed inside the rotation path of the drive member, the plurality of display boards may be arranged in a predetermined region facing each other of the drive member.

[For production]

The operation of the display device configured as described above is as follows.

When an endless drive member is rotated and a plurality of display boards arranged in a predetermined area of the drive member are stopped in front of a fixed display board, advertisements displayed on the surface of each display board can be viewed.

Next, when the drive member is rotated and passed through the first guide member disposed at one end of the rotation path of the drive member, each display board rotates at one end without tilting. As the vehicle passes by, each display board reaches the rear rotating path with the surface facing inward of the rotating path, and the fixed display board is displayed.

Furthermore, when the drive member passes the other end of the rotation path, each display board is rotated by a half turn by the second guide member so that the surface of each display board faces inward of the rotation path. held,
When the vehicle stops in front of the turning path again, the back side of each display board is displayed.

Thus, three different displays are produced during one revolution of the drive member.

The fixed display board disposed inside the drive member can be easily replaced from above because there is nothing obstructing the upper part.

In a display device in which a plurality of display boards are arranged in opposing predetermined areas of the drive member instead of a fixed display board, the display boards arranged in two areas stop alternately in front every half rotation. Therefore, four types of display are made while the driving member rotates one and a half rotations.
