For example, it is possible to display "Please move forward" and blink these characters, or move them to the right to call the driver's attention. Further, the display may be colored.
In that case, for example, one dot is made into a light emitting element of three colors,
By emitting light of a predetermined color, it is possible to create a character of an appropriate color.

<B> Position detecting element The position detecting element for detecting the entry position of the vehicle is a plurality of first position detecting elements 21 arranged in front of the entrance of the parking lot.
And a plurality of second position detecting elements 22 arranged in the back. The first position detection element 21 includes the first light emitting elements (a1 to a1).
5) and the first light receiving element (b1 to b5). Similarly, the second position detecting element 22 is the second light emitting element (a
6 to a10) and the second light receiving element (b6 to b10). The light emitting elements (a1 to a10) are at the bottom,
The light receiving elements (b1 to b10) are arranged above and along the approaching direction of the vehicle. Since the light emitted from the light emitting element is blocked by the vehicle body and the light receiving element cannot receive the light, the vehicle position can be detected. The signal detected by the position detection element is sent to the control device 7 via the cable 71. The control device 7 controls the display device 1 based on this signal.

<C> Rotary table 3 The rotary table 3 is rotatably controlled about a vertical axis,
It is used to rotate the vehicle at a right angle if necessary.
The turntable 3 has a pair of first correction rollers 40 on its upper surface.
And a pair of second correction rollers 50 are provided. These rollers correct the lateral position of the car body. That is, when the vehicle body is laterally displaced from the center position of the turntable 3, the correction roller rotates to forcibly move the vehicle body to the center. A rotary table recess 31 is provided at the center of the rotary table 3 in the entering direction. There are notches at both ends of the recess, and the first light emitting elements (a1 to a5) and the second light emitting elements (a6 to a10) are arranged below the notches. The light emitted from the light emitting element passes through this notch and reaches the light receiving element above.

<D> Correction Rollers 40, 50 FIGS. 3 to 4 show correction rollers arranged on the rotary table. The first correction roller 40 includes a plurality of roller groups 41, 42, ..., And the center line L of the rotary table 3.
Are arranged in parallel in parallel with. Each correction roller is set to have a gap that prevents the tire from falling. The second correction roller 50 also has the same structure as the first correction roller 40. The lengths of the first correction roller 40 and the second correction roller 50 are formed with a margin such that all four wheels can ride even in a vehicle model in which the distance between the front wheel F and the rear wheel R is different. The driving of the first correction roller 40 is performed by the sprocket 41a, 42a, ..., The drive unit 61 and the endless chain 63 provided at one end of each roller 41, 41 ,. The rollers 41, 42, ... And 46, 47, ... On both sides of the center line L of the first correction roller are rotated in the same direction by the drive unit 61. Similarly, the second correction roller 5
The rotation of 0 is also controlled by another drive unit (not shown) . A signal from an element (not shown) for detecting the lateral position of the vehicle is transmitted via the cable 71 to the controller 7
The rotation of the correction roller is controlled based on this signal. As a result, the front wheels F and the rear wheels R are carried by the rollers, and the vehicle is moved to the center position.

A method of guiding the vehicle will be described below. <B> Vehicle entry / forward When the vehicle enters the entrance of the parking lot, the display on the display device 1 in front of the driver is noticeable. At this time, the display device 1
Indicates that the vehicle is moving forward, for example, please move forward.
Further, when the vehicle moves forward, the first position detecting elements (a1, b
1) and (a2, b2) detect the tip of the vehicle one after another. <B> Vehicle deceleration When the first position detecting element (a5, b5) detects a vehicle,
The display device 1 displays deceleration, that is, drive slowly. Alternatively, the vehicle speed is calculated from the detection signal of the position detection element, and the same display is performed even when the approach speed is high.

<C> Stopping the Vehicle When the vehicle further enters, the second position detecting element 22 detects the front end of the vehicle and the first position detecting element 21 detects the rear end of the vehicle.
To detect. The center position of the vehicle is calculated by these first and second position detecting elements. Therefore, even if the vehicle body lengths are different, it is possible to know the center position of the vehicle. According to this measurement, when the vehicle comes to the stop position, the display device 1 displays a stop display, for example, stop. <D> Vehicle Retraction The vehicle position is detected by the first and second position detection elements, and when the vehicle has moved too far forward, the display device 1 displays a backward movement. When the display device retreats to an appropriate position, the display device switches the display and displays the stop. The stop position is wide enough to prevent an accident.

<E> Lateral correction of vehicle When the vehicle is laterally displaced, the front wheel F is forcibly moved to the center position by the rotation of the second correction roller 50. The position of the rear wheel R is similarly corrected by the first correction roller 40. <F> When the vehicle can be stopped at a predetermined stop position, the display device 1
Display cautions such as forgetting to pull the side brake or forgetting to remove the key. In this way, the driver can be used as an unmanned parking lot because it always calls the driver's attention.

[0013]

As described above, the present invention produces the following special effects. <B> Since the driving instruction can be displayed on the display device in correspondence with the entry position of the vehicle, even a beginner can accurately stop the vehicle at a predetermined position. <B> Since the position detection element detects the front end and the rear end of the vehicle, the center position of the vehicle can be detected even if the vehicle body length varies from vehicle to vehicle.
