Hereinafter, the present invention will be explained in detail using drawings showing embodiments thereof.

FIG. 1 is a perspective view of a display device that is an embodiment of the present invention. A plate 2 is placed on the mounting table 1, and a plate 2' is placed on the plate 2,
The rear edges of the plates 2 and 2' are fixed by a hinge 3.
A groove 1D with a width approximately the same as the width of the plate 2 extends back and forth on the upper surface of the mounting table 1, on the part where the plate 2 is placed.Since the plate 2 fits into the groove 1D, it cannot slide back and forth. However, the left and right sides are being restrained. This method does not require the provision of a groove on the mounting table 1, but can be done by providing a rail on the mounting table 1 and providing a groove on the plate 2, or by providing a long hole on the mounting table 1 and two protrusions on the plate 2. Any method may be used as long as it is a mechanism that slides back and forth but is restrained from side to side, such as by fitting it into an elongated hole.

A long hole 6 is provided on the top surface of the mounting table 1.
A swinging rod 4 protrudes from the elongated hole 6, passes through an elongated hole 2H provided in the plate 2, and rotatably locks its tip portion 4P to the plate 2' at a position slightly forward of the rotation axis of the hinge 3. has been done. The lower end of the swinging rod 4 is rotatably supported within the mounting table 1, and is configured to swing back and forth by a drive mechanism provided within the mounting table 1. Reference numerals 5 and 5' on the front side of the mounting table 1 are a pair of reflective sensors on the transmitting side and the receiving side, which detect the approach of an object.

FIG. 2 is a side sectional view illustrating the operating mechanism of this embodiment. The crank rod 8 has one end fixed to an output shaft 10 of a motor (not shown) or a reducer connected to the motor, and has a crank pin 9 at the other end. The crank pin 9 fits into an elongated hole 4H provided in the swinging rod 4, and when the crank rod 8 rotates due to the rotation of the output shaft 10, it slides in the elongated hole 4H, causing the swinging rod 4 to swing back and forth. let Reference numeral 11 causes the aforementioned swinging rod 4 to swing back and forth. Reference numeral 11 denotes a shaft on which the lower end of the swinging rod 4 described above is rotatably supported within the mounting table 1. Here, unless the distance between the output shaft 10 and the crank pin 9 is smaller than the distance between the output shaft 10 and the shaft 11, the swinging rod 4 will not swing back and forth.

Next, the operation of the display device in this embodiment will be explained step by step. First, when a person stands in front of this display device, the reflective sensor reacts, the motor is energized by the control circuit shown in FIG. 3, and the crank 8 is rotated. When the crank 8 rotates, the swinging rod 4 swings back and forth about the shaft 11 due to the movement of the crank pin 9 that fits into the elongated hole 4H. When the swinging rod 4 swings back and forth, the swinging rod 4
The plate 2', which is fixed to the tip of the plate, reciprocates back and forth, and the plate 2 also slides back and forth. Here, since the swinging rod 4 rotates around the shaft 11, the tip of the swinging rod 4 is set at the farthest point from the perpendicular line drawn from the shaft 11 to the top surface of the mounting table 1. moving away from or approaching the top surface. Therefore, the point of the plate 2' that locks the swinging rod 4 also moves away from or approaches the top surface of the mounting table 1. However, since the plate 2 slides along the top surface of the mounting table 1, the plate 2
The plate 2' opens and closes around the axis of the hinge 3 while moving back and forth. Here, the plates 2 and 2' are also opened the most when the swinging rod 4 is located at the perpendicular line mentioned above. In the figure, shaft 11 is output shaft 1
0, the plates 2 and 2' close at the rear and open most at the front, but the shaft 11 is located in front of the output shaft 1.
0, the plates 2 and 2' can be opened at the rear and closed at the front, or depending on the anteroposterior relationship between the shaft 11 and the output shaft 10, they are most open at other positions. You can also do it like this.

As described above, when a person stands in front of this display device, the drive mechanism is energized by the detection signal from the sensor, and the two plates move back and forth to open and close the display device. The energization is stopped, and the two plates stop operating and become in a standby state. In this way, the person who came in front of this display device noticed that the inanimate board, which had been stationary until then, began to move back and forth, as if a living thing was opening and closing its mouth, and was surprised and intrigued. It can be attached.

Here, the two plates that open and close should not be just flat plates, but should be decorated with three-dimensional decoration, for example in the shape of a hamburger, especially in a shape that imitates an object that can be opened and closed around one end. For example, you can give the impression that the object is alive, and if you add sound when it moves, you can give the impression that the object is flexible, which makes it even more surprising. By giving more information, you can attract more interest. Note that Fig. 3 shows a switch circuit that controls the operation and stop of the drive mechanism in this embodiment, and the motor is energized when there is a detection signal from the sensor, but there are various other circuits as well. Conceivable.

The above is the configuration of this embodiment. In this embodiment, a mechanism that rotates the crank 8 is used as the swing drive mechanism, but it is not limited to this. For example, a mechanism that swings a clock pendulum, a solenoid A mechanism using . In short, any mechanism may be used as long as it swings the swinging rod 4 in a plane parallel to the sliding direction of the plate 2.

Further, in this embodiment, the plate 2 is slid back and forth, but it may be slid sideways as well. In this case, the swinging rod 4 also swings left and right.

Furthermore, in this embodiment, a reflective sensor is used to perform an operation while a person is standing in front of it, but the present invention is not limited to this, and a Matsuto switch is used instead of a reflective sensor. The operation may be performed when a person stands on the matsuto switch, or the operation may be performed at regular intervals by a timer without using a sensor.

Furthermore, with regard to stopping the operation in this embodiment, a position sensor such as a micro switch is provided on the swinging rod 4 or the crank 8, so that the plate 2, 2' reaches the closed position after the person leaves. It is also possible to make the plates 2, 2' stop only when the plates 2 and 2' are moved, giving the impression that they are living things.

Effects As described above, according to the present invention, the two plates suddenly start moving in a humorous way, as if a living creature is opening and closing its mouth to announce its presence.
Not only can it attract the attention and interest of people nearby, but because it has an extremely simple structure, it can be manufactured compactly and at low cost, and when used in conjunction with products or product advertisements, it does not take up much space. It can be used as an easily available advertising device, etc.
It is possible to provide a display device that can also be used as an ornament in a house.
