The present invention relates to a competition determination device suitable for use in a water race such as a boat race where a visible goal line cannot be drawn.

"Prior Art" Conventionally, a determination device has been provided as a device for determining the order of arrival and flying in a race competition. This determination device is roughly configured by a camera called a slit camera and a light emitting display device that displays competition data by light emission. FIG. 6 is a device layout diagram when the conventional judging device is used for judging the arrival order of a boat race. In this figure, reference numeral 1 is a boat course, 2a to 2f are boats that are racing objects, 3 is a slit camera (described later) in which a slit is installed in front of a film, and 4a is a light emitting display unit that constitutes a part of a light emitting display device. Is. Slit camera 3 and light emitting display
4a are arranged opposite to each other on the extension line of the goal line AB via the boat course 1. Then, the boats 2a to 2f, which are race objects passing through the goal line A, are photographed, and a photograph determination of the order of arrival is made. At the time of photographing, the light emitting display unit 4a is also in an operating state, and bibliographical data such as a competition place is also photographed at the same time.

"Problems to be solved by the invention" By the way, in a track race (horse racing, etc.), it is possible to draw a goal line on the ground with a solid line, but in a water race (boat race, etc.), It is impossible to draw a solid goal line at.

For this reason, when the above-mentioned conventional determination device is applied to a water race, for example, the above-mentioned boat race, the slit camera 3 and the light emitting display unit 4a are accurately arranged facing each other on the invisible goal line. There was a problem that it was not always easy to do. If the installation position of the determination device is incorrect, the arrival order determination may be incorrect. For example, if the determination device is arranged on the line AB in FIG. 6, the boat 2f will be determined as the first place, but the line segment AC
If placed above, the boat 2a would be judged as the first place. As described above, according to the above-described conventional determination device, there is a disadvantage that the determination device is apt to be installed incorrectly, which may cause an error in the arrival order determination.

The present invention has been made in view of the above circumstances, and provides a determination device that is not likely to be installed outside the goal line even when applied to a water race where a solid goal line cannot be drawn. It is an object.

"Means for Solving the Problem" In order to solve the above-mentioned inconvenience, the present invention sequentially captures only the portions on a line of a plurality of moving objects that pass through a preset line, and A slit camera or a line sensor camera which projects a moving object in accordance with the order of passing through the line, and at least one or more light emitting units arranged in a direction perpendicular to the moving direction of the moving object, and through the line, A first light emitting means arranged opposite to the slit camera or the line sensor camera and on an extension of the line; and a light emitting portion, facing the slit camera or the line sensor camera and extending the line Second placed on the line
Light emitting means and light emitting control means for controlling the first and second light emitting means to simultaneously emit light at a predetermined interval, and the slit camera or line sensor camera, together with the plurality of moving objects, It is characterized in that each light emitting point of the first and second light emitting means is photographed.

[Operation] According to the configuration described above, the light emitting points of the first and second light emitting means are simultaneously imaged on the slit camera or the line sensor camera, so that the slit camera or the line sensor camera is on the extension line of the line. You can prove that it is installed in.

As a result, even in a water competition where a visible line cannot be drawn, it is possible to avoid the risk of installing the slit camera or the line sensor camera at a position that is not on the extension line of the line.
