The direct currents from the rectifiers 52d1, 52d2, 70, 71, 72 are combined and supplied to the arithmetic control circuit 80 after being converted into direct currents via 70, 71, 72.

As a result, the rectifiers 52d1, 52d2, 7
The combined current output from 0, 71, and 72 is
Even if the coil assembly 51 is located above the center of each of the primary coils 33 and 34, the level is substantially the same as when the coil assembly 51 is located on the adjacent portion of the primary coils 33 and 34. That is, this combined current is always constant regardless of the moving position of the coil assembly 51. Therefore, electric power can be supplied to the arithmetic and control circuit 80 without contact even when the traveling body 9 moves.

Further, the arithmetic control circuit 80 is composed of a rectifying circuit, 5
When the traveling body 9 is located at a position where the voltage supplied from 2d1, 52d2, 71, 72, 73 is high, the rectifier circuit 52d
1, 52d2, 71, 72, 73 part of the electric power supplied from the electric storage device 40 is charged to the rectifier circuit 52d1, 52d
When the traveling body 9 is located at a position where the voltage supplied from 2, 71, 72, 73 is low, the electric power from the battery 40 is used to control the drive of the motors 14, 17.

(Driving of the traveling body 9) Now, the arithmetic control circuit 80
When the electric power is supplied from the rectifiers 52d1, 52d2, 70, 71, 72, the drive pulse can be supplied to the motors 14, 17.

Then, the parallel movement control program recorded in the information recording / reproducing device 86 is read by the arithmetic control circuit 83, and the vertical movement control information of the parallel movement control program is optically communicated from the light emission control circuit 89. When input to the arithmetic control circuit 80 via the means 82, the arithmetic control circuit 8
Based on this control information, 0 supplies a drive pulse to the motor 14 to control the drive of the motor 14. When the traveling wheels 13, 13 are driven to rotate in the arrangement direction of the vertical rack 10 of the traveling plate 8 by the drive of the motor 14, the fitting grooves 13a, 13a of the pair of front and rear traveling wheels 13, 13 become The running bodies 9 are moved in the arrangement direction of the vertical racks 10 while sequentially meshing with the engagement protrusions 10a and 10a of the racks 10 alternately.

At this time, one of the fitting grooves 13a, 13a of the traveling wheels 13, 13 is always engaged with the engaging projection 10a of the traveling plate 8,
It does not slip like the drive mechanism of a conventional traveling body.
Therefore, the traveling body 9 can be reliably moved by an amount corresponding to the rotation speed of the traveling wheels 13.

Therefore, when a stepping motor or the like is used as the motor 14, the rotational speed of the traveling wheel 13 can be determined in advance by the number of pulses input to the motor 14, and the traveling distance can be controlled. The body 9 can be accurately moved to the target position. For this reason,
There is no need to perform feedback control by providing a moving distance sensor or the like for measuring the moving distance.

When the horizontal movement control information of the parallel movement control program is input from the controller 81 to the arithmetic control circuit 80 via the optical communication means 82, the arithmetic control circuit 80 uses the control information as a basis. A drive pulse is supplied to the motor 17 to control the drive of the motor 17.

When the motor 17 is driven to rotate the sprockets 28 and 29 through the pinion gear 26, the reduction gear portion 18a, and the rotary shaft 27, the traveling body 9a is mounted on the lateral rack 10a. Is moved in the direction.

At this time, even if the traveling wheels 13, 13 are rolling, the barrel bearing 21 of at least one traveling wheel 13 of the front traveling module M1 and at least one traveling wheel of the rear traveling module M2. Since the barrel bearing 21 of 13 abuts on the traveling plate 8 and supports the traveling body 9, the resistance when moving in the extending direction of the vertical rack 10 becomes the rolling resistance of the barrel bearing 21. In the conventional drive mechanism for a traveling body, the traveling body 9 can be moved obliquely or laterally with a smaller resistance than the sliding resistance generated between the drive wheel and the support shaft.

In the traveling mechanism of this embodiment, the front and rear traveling modules M1 and M2 are arranged in front of and behind the traveling body 9a, but the invention is not limited to this, and only one traveling module M1 or M2 is provided. You may make it arrange | position in the said traveling body main body 9a. Also in this case, since the barrel-shaped bearing 21 of at least one traveling wheel 13 is in contact with the traveling plate 8, the same resistance as in the case where the two barrel-shaped bearings 21 and 21 are in contact is provided with a small resistance. The traveling body 9 can be moved obliquely or laterally.

Moreover, in the conventional traveling body moving mechanism, when the drive wheels reach the end of the support shaft and come into contact with the side wall of the traveling body supporting the support shaft, the driving wheels are further moved in the left-right direction. Since the drive wheels cannot slide, the lateral movement of the traveling body is restricted.

On the other hand, in this embodiment, since the barrel bearing 21 rolls in the arrangement direction of the horizontal rack 10a,
It is possible to reliably move the traveling body 9 on the traveling plate 8 only in the arrangement direction of the lateral rack 10a without restricting the movement of the traveling body 9 in the lateral direction.

In the drive mechanism of the traveling body 9 of this embodiment, since the traveling body 9 can be moved smoothly also in the arrangement direction of the lateral rack 10a, the energy loss of the motor 17 can be suppressed to the minimum. It has become possible to reduce the size and weight of the means.

(Translation control and display body 200)

Further, the traveling direction of the traveling body 9 is changed to the left-right direction, so that the magnetic absorber 201 causes the magnet M of the traveling body 9 to move.
When following G, the display body 200 is in a state of rotating around the wheels 210 of the substantially rotary support body 203. At the time of this change, the support shaft 204 is rotated by the action of the thrust bearing 205 so that the wheel 206 faces the moving direction of the center of the support shaft 204. The movement at the time of changing the direction does not become the same as the previous movement even if the display body 200 is made to perform a complicated movement and the display body 200 is controlled to move in the same pattern.

As described above, a plurality of display bodies 200 are provided, and the movement of each display body 200 is controlled according to the individual program pattern to avoid collision. Moreover, the movement at the time of changing the direction is not exactly the same as the previous movement even if the display body 200 is made to perform a complicated movement and the display body 200 is controlled to move in the same pattern. As a result, a plurality of display bodies 200
By giving the movement of the story a story, it is possible to attract attention to the display and display without getting tired of what you see.

Further, the customer moves the traveling body 9 of the target display body 200 to the near side by the customer operating device 85, so that the target display body 200 can be observed closer.

(Input of Parallel Movement Control Program) Furthermore, for example, when changing the display of products, the movement pattern of the display body 200 can be changed by using the input device 84. In this case, as shown in FIG.
While simultaneously displaying the position 9a of the traveling body 9 that drives the vehicle and checking the position 9a of each traveling body 9, the position 9a of each traveling body 9 is slightly moved and changed by the input device 84, and the changed position is changed. It is stored at any time and a movement pattern is constructed. The constructed movement pattern is recorded in the information recording / reproducing device 86 as a parallel movement control program. In this way, the parallel movement control program can be easily changed.
