Description
本発明は、競馬、競輪、競艇、オート等の競技（レース）における電子判定装置のラインセンサーの方向を調整するためのあおり機構に関する。 The present invention relates to a tilt mechanism for adjusting the direction of a line sensor of an electronic determination device in a competition (race) such as horse racing, bicycle racing, boat racing, or auto.
従来、競馬等においてゴールライン上を連続してラインセンサーで撮像し、該撮像された画像から競馬等の着順判定やタイム表示を行うシステムが知られている。
前記競技用の電子判定装置にはラインセンサー（直線状のＣＣＤセンサー）が用いられており、該ラインセンサーは、レース場のゴールライン上を一定のスリット間隔でライン状に撮像し、該ライン状の画像を連続してモニター上に表示することにより着順判定画像としている。
2. Description of the Related Art Conventionally, a system is known in which a goal sensor is continuously imaged on a goal line in horse racing and the like, and arrival order determination and time display of horse racing are performed from the captured images.
A line sensor (linear CCD sensor) is used in the electronic judging device for competition, and the line sensor images the line on the goal line of the race track at a certain slit interval, These images are continuously displayed on the monitor to obtain an arrival order determination image.
これは、従来スリット・カメラでほぼ対象物（例えば、馬）の速度とほぼ同じ速度でフィルムを走らせて連続して撮影し、これを表示することにより着順判定画像としていたものをＣＣＤラインセンサーとモニターにより電子的に実現したものである。 This is a CCD line sensor that uses a slit camera to continuously shoot the film at approximately the same speed as the object (for example, a horse) and display it as an arrival order determination image. And electronically realized by a monitor.
図７に該着順判定画像の例を示す。なお、図７において、３１，３２は着順判定用のカーソル線である。審判員は、モニタに表示された映像において着順を判定する馬の先端にカーソル３１，３２を合わせて着順を判定する。 FIG. 7 shows an example of the arrival order determination image. In FIG. 7, 31 and 32 are cursor lines for determining the arrival order. The referee determines the arrival order by placing the cursors 31 and 32 on the tip of the horse for determining the arrival order in the video displayed on the monitor.
図６は、従来のスリットカメラを用いた着順判定装置の概念図を示す。図において、５１はレンズ、５２はスリットを有するスリット板、５３はフィルムであり、これらはカメラケースＣ内に収められている。ゴールライン５４上の物体像がレンズ５１およびスリットを通してフィルム５３上に結像するように配置し、フィルム５３をゴールライン上を通過する物体の速度で移動物体と逆方向に移動して巻き替えることにより図７に示すように、ゴールライン上を通過した移動物体の像がフィルムに写し込まれる。 FIG. 6 is a conceptual diagram of an arrival order determination apparatus using a conventional slit camera. In the figure, 51 is a lens, 52 is a slit plate having a slit, 53 is a film, and these are housed in a camera case C. The object image on the goal line 54 is arranged so as to form an image on the film 53 through the lens 51 and the slit, and the film 53 is moved in the direction opposite to the moving object at the speed of the object passing on the goal line and rewinded. As shown in FIG. 7, the image of the moving object that has passed over the goal line is imprinted on the film.
現在、前記競技用の電子判定装置には上記スリットカメラに替えてラインセンサー（直線状のＣＣＤセンサー）が用いられており、該ラインセンサーは、レース場のゴールライン上を一定のスリット間隔でライン状に撮像し、該ライン状の画像を連続してモニター上に表示することにより着順判定画像としている。 At present, a line sensor (linear CCD sensor) is used in the electronic judging device for competition instead of the slit camera, and the line sensor is arranged on the goal line of the race track at a certain slit interval. The line-shaped images are continuously displayed on the monitor to obtain an arrival order determination image.
上記ラインセンサ−は、正確にゴールライン上に合わせる必要がある。ゴールライン（判定基準線）とラインセンサーの撮像方向にずれが生じていると、正確に着順判定ができないことになる。例えば、ゴールラインとラインセンサーが僅かでも角度をもって設置されると、ゴールラインに到達した位置によって遅れて入った馬等が先に検出されたり、あるいは順位が同着と判定されてしまうことになる。また、ゴールラインとラインセンサーの方向が左右にずれると、その分ゴールラインからずれた位置で着順判定をすることになってしまう。 The line sensor needs to be accurately aligned on the goal line. If there is a deviation between the goal line (judgment reference line) and the imaging direction of the line sensor, the arrival order cannot be determined accurately. For example, if the goal line and the line sensor are installed with even a slight angle, a horse or the like that is delayed depending on the position that has reached the goal line will be detected first, or the rank will be determined to be the same. . In addition, if the direction of the goal line and the line sensor is shifted to the left or right, the arrival order is determined at a position shifted from the goal line.
競馬等においては、鼻の差で着順が決まるので、上記ラインセンサーを正確にゴールライン上に合わせることは重要である。
このため、上記従来の電子判定装置は、例えば、特開平６−２７６５２６号や特開平４−２６８５４８号公報に示されるように、図６のレンズ５１とスリット５２の間で分光してビューファインダでラインセンサーをゴールラインに合わせていた。
In horse racing and the like, the order of arrival is determined by the difference in the nose, so it is important to accurately align the line sensor on the goal line.
For this reason, the above-described conventional electronic determination device performs spectroscopic analysis between the lens 51 and the slit 52 in FIG. 6 and uses a viewfinder as disclosed in, for example, Japanese Patent Application Laid-Open Nos. 6-276526 and 4-268548. The line sensor was aligned with the goal line.
そのライン合わせの例が、特表平８−５０６２２５号公報にも示されている。このように、電子判定装置は判定基準線であるスタートラインまたはゴールライン上にラインセンサが正確に重なり合うように設置される。 An example of the line alignment is also shown in JP-T-8-506225. In this way, the electronic determination device is installed so that the line sensors accurately overlap the start line or goal line that is the determination reference line.
このライン合わせには、ラインセンサーを設置した基板の左右、バックフォーカス調整と共に、あおり角度（ラインを見る仰角）の調整が必要である。
従来、これら左右、あおり角、バックフォーカス調整は、ラインセンサーや回路を組み込んだ筐体の中に一体に設けられていたため、左右調整、あおり角調整、及びバックフォーカス調整を行うとカメラは固定され、再度調整することは非常に困難であった。
For this line alignment, it is necessary to adjust the tilt angle (the elevation angle at which the line is viewed) as well as the left and right and back focus adjustment of the substrate on which the line sensor is installed.
Conventionally, these left / right, tilt angle, and back focus adjustments were integrally provided in a housing incorporating a line sensor and circuit, so the camera is fixed when left / right adjustment, tilt angle adjustment, and back focus adjustment are performed. It was very difficult to adjust again.
しかし、あおり角度だけ調整したいような場合もあり、そのような場合に左右調整やバックフォーカス調整はそのままに、あおり角度のみ調整できると便利である。従来のものでは、すべて調整済みで固定されるので、再度調整しようとすると、すべて内部を開けて調整し直すので、あおり角度のみならず、左右調整やバックフォーカス調整まで最初からやり直す必要があった。
本発明は、ラインセンサーを用いた電子判定装置において、ラインセンサーのあおり角を左右調整やバックフォーカス調整をいじることなく、調整できるように、あおり角調整機構を左右調整やバックフォーカス調整と別機構にして、あおり角のみを容易に調整できるカメラ機構を提供することを目的とする。 The present invention relates to an electronic determination device using a line sensor, wherein the tilt angle adjustment mechanism is different from the left / right adjustment and back focus adjustment so that the tilt angle of the line sensor can be adjusted without changing the left / right adjustment or the back focus adjustment. It is an object of the present invention to provide a camera mechanism that can easily adjust only the tilt angle.
上記目的を達成するため、本発明の競技用電子判定装置のカメラヘッドは、レース場のゴールライン上を一定のスリット間隔でラインセンサーにより撮像し、該ライン状の画像を連続してモニター上に表示することにより着順判定画像とする競技用電子判定装置のカメラヘッドにおいて、ラインセンサーの左右のブレを調整する機構とバックフォーカス機構を有する前面板筐体、ラインセンサーおよび該ラインセンサーの制御回路を設けたプリント基板を有するラインセンサー設置筐体からなり、上記ラインセンサー設置筐体が上記前面板筐体に対して組み込まれ、かつ前傾または後傾方向に回転可能とすることにより、前面板筐体とラインセンサー設置筐体との間の組み込み角度が微調整され、該微調整により上記ラインセンサーのあおり角を調整することを特徴とする。 In order to achieve the above object, the camera head of the electronic judging device for competition according to the present invention images a line on the goal line of the race track with a line sensor at a constant slit interval, and continuously displays the line-shaped image on the monitor. In a camera head of an electronic judging device for competition which is displayed as an arrival order judging image by displaying, a front plate housing having a mechanism for adjusting left and right blur of the line sensor and a back focus mechanism, a line sensor, and a control circuit for the line sensor A line sensor installation housing having a printed circuit board provided with the line sensor installation housing, wherein the line sensor installation housing is incorporated with respect to the front plate housing and is rotatable forward or backward. The installation angle between the case and the case where the line sensor is installed is finely adjusted. And adjusting the.
さらに、前記前面板筐体の中心には垂直方向にあおり機構の調整用基準棒を設け、かつラインセンサー設置筐体にはあおり角度調整用のテーパー状（円錐状）の径をもつピンを設けて、上記あおり角度調整用の円錐状の径をもつピンの円錐状径の部分は上記あおり機構の調整用基準棒にバネ機構により圧接され、上記ピンのテーパー状（円錐状）径の部分を左右に移動させてラインセンサー設置筐体の前面板筐体に対する距離が調整されることによりラインセンサー設置筐体が前面板筐体に対して前傾または後傾方向に回転し、上記前面板筐体とラインセンサー設置筐体との間の組み込み角度が微調整されることを特徴とする。 Further, a vertical adjustment mechanism reference rod is provided in the center of the front plate casing, and a taper (conical) diameter pin for adjusting the tilt angle is provided on the line sensor installation casing. The conical diameter portion of the pin having the conical diameter for adjusting the tilt angle is pressed against the adjustment reference rod of the tilt mechanism by a spring mechanism, and the tapered (conical) diameter portion of the pin is By moving the line sensor installation housing to the left and right and adjusting the distance of the line sensor installation housing to the front plate housing, the line sensor installation housing rotates forward or backward with respect to the front plate housing. The installation angle between the body and the line sensor installation housing is finely adjusted.
本発明のカメラヘッドによれば、ラインセンサーの左右のブレを調整する機構とバックフォーカス機構を有する前面板筐体とラインセンサーおよび該ラインセンサーの制御回路を設けたプリント基板を有するラインセンサー設置筐体とを別体にして組み込み可能にし、一旦調整したラインセンサーの左右のブレを調整する機構とバックフォーカス機構を有する前面板筐体の調整箇所を固定したまま、ラインセンサーのあおり角のみを調整できるので、従来のようにあおり角調整の際にすべての調整をやり直す必要がないので、あおり角調整が容易に、簡単にできるようななった。 According to the camera head of the present invention, a line sensor installation housing having a front plate housing having a mechanism for adjusting left and right blur of the line sensor, a back focus mechanism, a line sensor, and a printed circuit board provided with a control circuit for the line sensor. The body can be assembled separately and adjusted, and only the tilt angle of the line sensor is adjusted while fixing the adjustment position of the front panel housing that has the back focus mechanism and the mechanism that adjusts the left and right blur of the line sensor once adjusted. Because it is possible, it is not necessary to redo all adjustments at the time of adjusting the tilt angle as in the past, so that the tilt angle can be adjusted easily and easily.

FIG. 1 shows an entire exploded view of the front plate housing 1. In FIG. 1, reference numeral 2 denotes a front plate, and a line sensor receiving plate 4 into which a line sensor is fitted behind the front plate 2 is screwed. In the center of the line sensor receiving plate 4, a pin 6 that fits into a groove of a line sensor front plate, which will be described later, is provided. On the upper rear side of the front plate 2, there is provided a reference rod 7 for adjusting the tilt mechanism described later.
The front plate 2, the line sensor receiving plate 4, the reference rod for adjusting the tilt mechanism and the like are all integrated by screwing to form the front plate housing 1.
図２は、上記前面板筐体に嵌合させて用いられるラインセンサー設置筐体８を示す。
図２において、９はラインセンサー前面板であり、該ラインセンサー前面板の中央部には溝１８，１９が切られていて、該溝１８，１９は、カメラを組み込んで使用する時、前記ラインセンサー受け板４の中央に設けられたピン６にはめ込まれる。１０は近赤外カットフィルタガラスであり、１１はラインセンサーのＣＣＤ撮像素子である。２０，２１，２２はプリント基板取り付け板であり、ラインセンサー１１を設置した前面プリント基板１２と該プリント基板から左右に延在するプリント基板取り付け板２０，２２からなる筐体が形成される。該プリント基板取り付け板２０，２１，２２にはラインセンサーの駆動処理を行う回路基板が設置されている。プリント基板取り付け板２０，２２の上方には、あおり角度調整用のテーパー状（円錐状）の径をもつピン１３が嵌挿されている。また、上記前面プリント基板２１の背後には、放熱板１６及び冷却用のファン１７が設けられている。
FIG. 2 shows the line sensor installation housing 8 used by being fitted to the front plate housing.
In FIG. 2, 9 is a line sensor front plate, and grooves 18 and 19 are cut in the center of the line sensor front plate, and the grooves 18 and 19 are used when the camera is incorporated and used. It fits into a pin 6 provided in the center of the sensor receiving plate 4. 10 is a near-infrared cut filter glass, and 11 is a CCD image sensor of a line sensor. Reference numerals 20, 21, and 22 denote printed circuit board mounting plates, which are formed with a casing including a front printed circuit board 12 on which the line sensor 11 is installed and printed circuit board mounting plates 20 and 22 extending from the printed circuit board to the left and right. The printed circuit board mounting plates 20, 21, and 22 are provided with circuit boards that perform line sensor drive processing. A pin 13 having a tapered (conical) diameter for adjusting the tilt angle is fitted above the printed circuit board mounting plates 20 and 22. A heat radiating plate 16 and a cooling fan 17 are provided behind the front printed circuit board 21.
これらラインセンサー前面板９，近赤外カットフィルタガラス１０，ラインセンサーのＣＣＤ撮像素子１１，プリント基板取り付け板２０，２１，２２、放熱板１６及び冷却用のファン１７はすべてねじ止めにより一体化されてラインセンサー設置筐体８となる。図３には、上記ラインセンサー設置筐体８の正面図、側面図、底面図を示す。 These line sensor front plate 9, near-infrared cut filter glass 10, line sensor CCD image pickup device 11, printed circuit board mounting plates 20, 21, 22, heat sink 16 and cooling fan 17 are all integrated by screwing. Thus, the line sensor installation housing 8 is obtained. FIG. 3 shows a front view, a side view, and a bottom view of the line sensor installation housing 8.
図４には、組み立て後の上記前面板筐体１を後方から見た平面図（図１において、右方向から見た図）を示す。図４において、７は、図１のあおり機構の調整用基準棒７であり、図４の左方、および下方には、ラインセンサー設置筐体８のあおり角度調整用のテーパー状（円錐状）の径をもつピン１３と上記あおり機構の調整用基準棒７との関係を示す上面図及び横断面図を示す。３８はベルトであり、４箇所のプーリー３４，３５，３６，３７に巻かれており、該ベルトの回転により図示されないバックフォーカス機構が調整される。長円形の穴４１，４２，４３はラインセンサーの上下、左右のブレの調整に用いられる。ラインセンサーの長手方向は正確にゴールライン上に合わせる必要があり、このため図３に示される光学系１４内のビューファインダー２５内の基準線とラインセンサ信号が一致するように上記長穴内のネジ止め位置が調整される。 FIG. 4 shows a plan view (as viewed from the right in FIG. 1) of the front panel housing 1 after assembly as viewed from the rear. 4, 7 is a reference rod 7 for adjusting the tilting mechanism of FIG. 1. On the left side and the lower side of FIG. 4, a tapered shape (conical shape) for adjusting the tilt angle of the line sensor installation housing 8 is shown. The top view and cross-sectional view which show the relationship between the pin 13 which has the diameter of this, and the reference | standard reference | standard 7 for adjustment of the said tilt mechanism are shown. A belt 38 is wound around four pulleys 34, 35, 36, and 37, and a back focus mechanism (not shown) is adjusted by the rotation of the belt. The oval holes 41, 42, and 43 are used to adjust the vertical and horizontal blur of the line sensor. The longitudinal direction of the line sensor needs to be accurately aligned with the goal line. For this reason, the screw in the elongated hole is set so that the reference line in the viewfinder 25 in the optical system 14 shown in FIG. The stop position is adjusted.
なお、ビューファインダ２５は、前述される従来のものと同様のもので、レンズとラインセンサー間に設置され撮像光を分光してラインセンサーの方向を基準方向に調整するためのものである。 The viewfinder 25 is the same as the conventional one described above, and is installed between the lens and the line sensor to divide the imaging light and adjust the direction of the line sensor to the reference direction.
図４に示されるように、上記あおり角度調整用の円錐状の径をもつピン１３の円錐状径の部分は上記あおり機構の調整用基準棒７に後述するバネ機構により圧接されている。従って、ネジ２３を回転させると、ピン１３のテーパー状（円錐状）径の部分は左右（図４左側面図において、上下方向）に移動し、このことにより図４の矢印Ａのごとくラインセンサー設置筐体８が前面板筐体１に対する距離が調整されてラインセンサー設置筐体８が前面板筐体１に対して前傾または後傾に回転し、前面板筐体１とラインセンサー設置筐体８との間の前傾または後傾の角度が微調整される。 As shown in FIG. 4, the conical diameter portion of the pin 13 having the conical diameter for adjusting the tilt angle is pressed against the adjustment reference rod 7 of the tilt mechanism by a spring mechanism described later. Therefore, when the screw 23 is rotated, the tapered (conical) diameter portion of the pin 13 moves to the left and right (up and down in the left side view of FIG. 4), and as a result, the line sensor as indicated by the arrow A in FIG. The distance between the installation housing 8 and the front plate housing 1 is adjusted, and the line sensor installation housing 8 rotates forward or backward with respect to the front plate housing 1, so that the front plate housing 1 and the line sensor installation housing are rotated. The forward or backward tilt angle with the body 8 is finely adjusted.
このことは、前面板筐体１は、ゴールライン方向に合わせて固定されて設置されているので、上記角度調整をすれば、ラインセンサー１１のあおり角が微調整されることになる。
なお、この場合のあおり角度とは、ラインセンサーの視点先が、垂直線上を上下する時の水平線と視点先とのなす角度（仰角）のことをいう。
This is because the front plate housing 1 is fixed and installed in accordance with the goal line direction, so that the tilt angle of the line sensor 11 is finely adjusted by adjusting the angle.
Note that the tilt angle in this case refers to an angle (elevation angle) between the horizontal line and the viewpoint point when the viewpoint point of the line sensor moves up and down on the vertical line.
図５に上記あおり角度調整用の円錐状の径をもつピン１３の円錐状径の部分と上記あおり機構の調整用基準棒７を圧接するためのバネ機構の例を示す。
バネ４６は、例えば図５に示すように、前面板筐体１の上部の係止穴４５とラインセンサー設置筐体８のプリント基板取り付け板２０，２２間に支持されたピン４７（図２に図示されていないが、図２のピン１５と同様のもの）との間に他のピン等に干渉しないように張られる。このことにより、ラインセンサー設置筐体８が前面板筐体１に対して前傾方向へ回転する方向に付勢され、上記あおり角度調整用の円錐状の径をもつピン１３の円錐状径の部分と上記あおり機構の調整用基準棒７を圧接する。なお、上記バネは上記箇所ではなく、その他の箇所でもラインセンサー設置筐体８が前面板筐体１に対して前傾方向へ回転する方向に付勢する位置であれば、どこでもよい。
FIG. 5 shows an example of a spring mechanism for press-contacting the conical diameter portion of the pin 13 having the conical diameter for adjusting the tilt angle and the adjusting reference rod 7 of the tilt mechanism.
For example, as shown in FIG. 5, the spring 46 is a pin 47 (see FIG. 2) supported between the locking hole 45 at the top of the front plate housing 1 and the printed circuit board mounting plates 20 and 22 of the line sensor installation housing 8. Although not shown, it is stretched so as not to interfere with other pins or the like. As a result, the line sensor installation housing 8 is urged in a direction that rotates forward with respect to the front plate housing 1, and the cone diameter of the pin 13 having the conical diameter for adjusting the tilt angle is increased. The portion and the reference rod 7 for adjusting the tilt mechanism are pressed against each other. Note that the spring is not limited to the above location, but may be any other location as long as the line sensor installation housing 8 is urged in the direction of rotating forward with respect to the front plate housing 1.
本発明のカメラヘッドを用いれば、ラインセンサーのあおり角の調整が他のバックフォーカスや左右調整を固定のままできるので、レース毎にあおり角を変更することもさほど困難ではなく、より的確な着順判定が簡便にできるようになったので、産業上の利用性は高い。 With the camera head of the present invention, the tilt angle of the line sensor can be adjusted with the other back focus and left / right adjustments fixed, so it is not difficult to change the tilt angle for each race. Since the order determination can be easily performed, industrial applicability is high.
