【発明の属する技術分野】
本発明は、遊技盤に設けられた障害釘を読み取る遊技盤読取装置に関する。
【0002】
【従来の技術】
周知のようにパチンコ機は、遊技盤の遊技領域に多数の障害釘が植設されており、これら障害釘の配置態様によってその入賞状態が決定され、たとえ同一の機種であっても、障害釘の相互間隔がわずかでも相違すれば遊技球通過の難易が大きく変化し、これに伴って各種入賞口に対する遊技球の入賞率に多大な影響を及ぼすようになる。従って、パチンコ機を設置する遊技店においては、遊技盤に設けられた障害釘の植設状態を如何に正確に把握できるかが、収支に基づく経営状態をバランスさせる上できわめて重要な課題となる。
【0003】
このため本件特許出願人は、特開2000−288173号公報に示されるような障害釘の状態判定方法を既に提案している。すなわち、基準となる遊技盤の画像と判定対象となる遊技盤の画像とを取得し、両画像を対応付けて重ね合わせることで判明する障害釘の位置ずれから、判定対象となる遊技盤に植設された障害釘の状態を判定しようとするものである。この方法によれば、基準となる遊技盤に植設された障害釘と、判定対象となる遊技盤に植設された障害釘との位置ずれが画像上に明確に現れるようになるため、特別な技能を有することなく障害釘の正確な植設状態を容易に、かつ客観的に判定することができるようになる。
【0004】
【発明が解決しようとする課題】
ところで、上述した障害釘の状態判定方法は、遊技盤の画像情報を正確に取得することが前提となる。しかしながら、上述した特開2000−288173号公報で例示するようにデジタルスチルカメラを適用した場合には、当該デジタルスチルカメラの取り扱い自体は容易であるものの、取得した画像の周縁部に比較的大きな歪みが発生する場合が多く、この歪みが障害釘の判定にも多大な影響を及ぼす虞れがある。
【0005】
しかも、遊技盤に対する撮像範囲がきわめて小さいため、1台のパチンコ機に対して多数の画像を取得する作業が必要となる。この結果、作業性の点において好ましいものとはいえないばかりか、個々の画像で撮影角度が異なる等、取得した画像毎に撮影条件が相違する確率も高くなり、最終的に得られる全体画像の正確性を低下させる要因ともなり得る。
【0006】
本発明は、上記実情に鑑みて、正確な遊技盤の画像情報を容易に取得することのできる方法及びその装置を提供することを解決課題とする。
【0007】
【課題を解決するための手段】
請求項1に記載の発明は、前面に画像入力面を有する外枠体と、前記外枠体の内部に支持されて前記画像入力面に沿って往復移動する読取ユニットとを備えるイメージスキャナと、前記イメージスキャナの画像入力面を垂直方向および水平方向に回転可能に前記イメージスキャナを支持する支持手段と、前記イメージスキャナの画像入力面がパチンコ機の遊技盤の所定の遊技領域に対応する高さ配置となるように前記支持手段をパチンコ機の設置された高さに対応させて固定する架台と、前記外枠体の画像入力面の周縁部を囲って環状に形成され、前記支持手段により前記画像入力面を前記遊技盤の遊技領域に所定間隔で近接配置させたときに前記遊技領域と前記画像入力面の周縁部を囲って環状に覆うフードと、前記外枠体または前記フードに設けられ、先端部を走査対象物となる前記遊技盤の盤面に当接させることにより、前記遊技盤の盤面に対する前記イメージスキャナの画像入力面が平行となるように規制して前記遊技盤の盤面から障害釘の先端までが前記読取ユニットの被写界深度内に位置するように所定長さの突き出し部材で構成された位置決めピンと、を備えたことを特徴とする遊技盤読取装置である。
【0011】
【発明の実施の形態】
以下、実施の形態を示す図面に基づいて本発明を詳細に説明する。
図1、図2および図3は、本発明に係る遊技盤読取装置の一実施形態を示したものである。また、図4は遊技盤読取装置の使用例を示す概略図で、店舗に設置されているパチンコ機に遊技盤読取装置を使用している状態を示している。ここで例示する遊技盤読取装置1は、パチンコ機Aの遊技盤Bに構成された遊技領域Cを撮像するためのものである。パチンコ機Aは、上部皿3、下部皿4、遊技盤Bなどを備えている。また、遊技盤読取装置1は、読取ユニット10が画像入力面10aに沿って矢印で示す左右方向に往復移動するイメージスキャナ20を備えている。
【0012】
読取ユニット10は、ユニット筐体11と、このユニット筐体11の内部に収容した光源12、リニアイメージセンサ13およびレンズ14を備えて構成してある。ユニット筐体11は、撮像すべき遊技領域Cの高さ寸法よりも大きな長さを有した角筒状を成し、その一側壁に読取用開口11aを設けたものである。光源12は、ユニット筐体11の読取用開口11aを通じて走査対象物に斜め方向から光を照射するためのもので、当該ユニット筐体11のほぼ全長に亘る部位に読取用開口11aの左右の両側に配置してある。図2からも明らかなように、この光源12の周囲には、当該光源12から発せられた光が走査対象物に対して効率良く照射されるように、その一部にランプリフレクタ15を設けてある。光源12としては、蛍光ランプ、希ガスランプ、ハロゲンランプ、LED等、適宜のものを適用すればよい。リニアイメージセンサ13は、CCD等の光電変換素子を直線状に配列することによって構成したもので、ユニット筐体11の読取用開口11aに対向する部位に取り付けてある。レンズ14は、光源12の光照射による走査対象物からの反射光をリニアイメージセンサ13に結像させるためのもので、読取用開口11aとリニアイメージセンサ13との間に設けてある。
【0013】
外枠体21の内部には、それぞれ上下各一対のガイドレール22が取り付けられている。外枠体21は遊技盤Bとほぼ同じ大きさの前面を有したもので、該前面の中央部に画像入力面10aを有している。画像入力面10aは、一辺の長さが遊技領域Cの長径よりも大きな矩形状を成すものである。ガイドレール22は、それぞれ外枠体21の内部において左右方向に沿って延在しており、互いの間に読取ユニット10を移動可能に支持するものである。この場合、読取ユニット10は、これらのガイドレール22に沿う移動が画像入力面10aに沿った適正な移動となるように、ユニット筐体11が上下方向(紙面垂直方向)に沿い、かつ読取用開口11aが画像入力面10aを介して外部に臨む姿勢で外枠体21の内部に支持させてある。なお、外枠体21には、モータ等の駆動手段Mが設けてある。この駆動手段Mは、常態において読取ユニット10を外枠体21の正面向かって右側となる初期位置に保持させる一方、起動スイッチ(図示せず)がONされた場合に所定の速度で読取ユニット10を左側に副走査移動させ、その後再び初期位置に復帰させるように機能する。
【0014】
また、イメージスキャナ20の外枠体21には、画像入力面10aの外側の周縁部を囲うようにフード30が固定されている。フード30は、画像入力面10aを遊技盤の遊技領域Cに所定間隔で近接配置させたときに、遊技盤の遊技領域Cと画像入力面10aの周縁部を囲って環状に覆い外光の影響を防止する。このフード30には、その前面周囲の複数箇所、具体的には少なくとも3カ所に位置決めピン33を設けてある。
【0015】
位置決めピン33は、個々の先端部を走査対象物に当接させることにより、当該走査対象物に対する外枠体21の姿勢を規制するためのものである。各位置決めピン33は、遊技盤Bに植設した障害釘Dの突出長さよりも大きく、しかも個々の先端部を走査対象物に当接させた場合に当該走査対象物の前面から手前側20mm程度の範囲が上述した読取ユニット10の被写界深度と合致するように所定長さの突き出し部材で構成され、また、その付け根部分が蝶番で結合されて必要に応じて折り畳み可能に構成してある。これら位置決めピン33は、フード30に設ける代わりに、イメージスキャナ20の外枠体21の前面周囲の複数箇所に設けることもできる。
【0016】
外枠体21の左右の側面には、一対の水平軸21a,21aが設けられている。この一対の水平軸21a,21aは、支持枠体40の左右の側面に回転可能に支持され、イメージスキャナ20は、画像入力面10aが外枠体21を介して垂直回転する態様で支持枠体40に支持される。
また、支持枠体40の一方の側面には、垂直方向の回転位置を微調整する微調整突起41が設けられ、微調整突起41に螺合された調整ねじ41aを回転して、外枠体21の一方の側面に設けられた突起23を押圧する。こうして支持枠体40の側面の調整ねじ41aを回転して、支持枠体40に対する外枠体21の回転位置を微調整することができる。
【0017】
また、支持枠体40の上下の側面には一対の垂直軸40a,40aが設けられている。枠の形状がコ字状の支持枠体50は、一対の支持バー50a,50aを回転軸50bで上下に連結した形状であり、支持枠体40の一対の垂直軸40a,40aはコ字状の支持枠体50の一対の支持バー50a,50aに回転可能に支持され、イメージスキャナ20は、画像入力面10aが外枠体21及び支持枠体40を介して水平回転する態様で支持枠体50に支持される。
【0018】
枠の形状がコ字状の支持枠体60は、一対の支持バー61a,61aを角筒部材62で上下に連結した形状であり、一対の支持バー61a,61aにはそれぞれ一対の垂直軸63a,63aが設けられている。また、下側の支持バー61aには油圧により伸縮する伸縮部材65及びその先端には係止片64が設けられている。この一対の垂直軸63a,63aには、支持枠体50の回転軸50bが回転可能に支持される。
【0019】
架台70は、左右両端下部に一対の脚部71a,71aを有したもので、各脚部71a,71aの下端に設けた車輪72によって床面上を適宜走行することが可能な走行枠体で形成した。架台70の脚部71a,71aは、図4に示すように、遊技店において各パチンコ機Aの前方に設置されている椅子Eの全高よりも大きな長さを有したものである。
この架台70の脚部71aの一方には支持枠体60の角筒部材62が嵌め込まれ、下側の支持バー61aに設けられた係止片64でねじにより、支持枠体60は脚部71aに固定されるが、伸縮部材65を伸縮させることで、脚部71aに対しての支持枠体60の取付け高さを調整することができる。この場合、支持枠体60が係止片64で脚部71aに固定される高さに多少の誤差があっても、遊技領域Cに対して画像入力面10aが大きく、画像入力面10aが遊技盤Bの遊技領域に設けられた障害釘をイメージスキャナで十分に読み取ることが可能な場合には、伸縮部材65を使用せずに鋼材などの長さの変化しない部材を使用することができる。
【0020】
上記のように構成した遊技盤読取装置1によって遊技領域Cを撮像する場合には、まず、図4に示すように、架台70を適宜走行させてパチンコ機Aのガラス枠Fを開き、架台70を遊技盤Bの前面に配置する。そして、フード30に設けた位置決めピン33の各先端をそれぞれ遊技盤Bの前面、好ましくは遊技領域外に当接させる。このとき、架台70に対して支持枠体40が適宜水平回転するとともに、支持枠体40に対してイメージスキャナ20の外枠体21が適宜垂直回転するため、遊技盤Bが如何なる姿勢であってもイメージスキャナ20の画像入力面10aは、垂直方向および水平方向に回転可能であり、3つの位置決めピン33を確実に遊技盤Bの前面に当接させることができる。
【0021】
ここで、3つの位置決めピン33が遊技盤Bの盤面に当接した状態においては、イメージスキャナ20の画像入力面10aが遊技盤Bの盤面と平行となり、しかも遊技盤Bの盤面から障害釘Dの先端までが読取ユニット10の被写界深度内に位置するようになる。従って、この状態から読取ユニット10を動作させ、具体的には光源12を点灯した状態でリニアイメージセンサ13による光電変換を開始し、さらに駆動手段Mによって当該読取ユニット10を移動(走査)させれば、遊技領域Cの全面に亘る広範な画像情報(遊技盤Bに貼着したセル画や障害釘Dを含んだもの)を一時に取得することが可能になる。
【0022】
そして、イメージスキャナ20で読み取った画像情報により、障害釘Dの位置ずれを調整したい場合には、回転軸50bでコ字状の支持枠体50を回転させて、支持枠体40及びこの支持枠体40に支持されているイメージスキャナ20等を支持枠体40ごと架台70の枠外方向に移動させる。そして、架台70の枠内でパチンコ機Aの遊技盤Bの略全面が見えるようにして、障害釘Dの調整作業を行うことができる。
【0023】
なお、イメージスキャナ20の画像入力面10aは、必ずしも遊技領域の全面の大きさである必要はなく、必要な部位のみを走査すれば十分である。
【0024】
【発明の効果】
以上説明したように、本発明の遊技盤読取方法によれば、デジタルスチルカメラを適用した場合のように、1台のパチンコ機に対して多数の画像を取得する作業が不要となり、作業性の点できわめて有利となる。
従って、この取得した画像情報をディスプレイ等に視認できる画像として表示させ、この表示された画像に基づいて障害釘Dの植設状態を判
定すれば、遊技店の収支に基づく経営状態をより正確にバランスさせることができるようになる。
【0025】
また、本発明の遊技盤読取装置によれば、パチンコ機の遊技盤の所定の遊技領域にイメージスキャナの画像入力面を位置決め設定し、該遊技領域に設けられた障害釘をイメージスキャナで読み取るようにしているため、二次元センサを用いるデジタルスチルカメラに比べて、歪みの少ない正確な画像を遊技盤の広範に亘って一度に取得することが可能になる。従って、例えばこの取得した画像に基づいて判定を行えば、より正確な障害釘の植設状態を容易に把握することができるようになる。

BACKGROUND OF THE INVENTION
The present invention relates to a game board reading device for reading an obstacle nail provided on a game board .
[0002]
[Prior art]
As is well known, pachinko machines have many obstacle nails planted in the game area of the game board, and the winning state is determined by the arrangement of these obstacle nails. Even if the mutual distance is slightly different, the difficulty of passing through the game ball changes greatly, and accordingly, the winning rate of the game ball with respect to various winning ports is greatly affected. Therefore, in a game store where a pachinko machine is installed, it is an extremely important issue to balance the management status based on the balance of payments how accurately the state of the obstacle nails provided on the game board can be grasped. .
[0003]
For this reason, the present applicant has already proposed a method for determining the state of the obstacle nail as disclosed in Japanese Patent Laid-Open No. 2000-288173. In other words, the image of the reference game board and the image of the game board to be determined are acquired, and the position difference of the obstacle nail that is found by associating and superimposing both images is placed on the game board to be determined. It is intended to determine the state of the obstacle nail provided. According to this method, since the positional deviation between the obstacle nail implanted in the reference game board and the obstacle nail implanted in the game board to be judged appears clearly on the image, Therefore, it is possible to easily and objectively determine the correct installation state of the obstacle nail without having the necessary skills.
[0004]
[Problems to be solved by the invention]
By the way, the above-described obstacle nail state determination method is premised on accurately obtaining image information of the game board. However, when a digital still camera is applied as exemplified in the above-mentioned Japanese Patent Application Laid-Open No. 2000-288173, the digital still camera is easy to handle, but a relatively large distortion occurs in the peripheral portion of the acquired image. In many cases, this distortion may greatly affect the determination of a faulty nail.
[0005]
Moreover, since the imaging range for the game board is extremely small, it is necessary to obtain a large number of images for one pachinko machine. As a result, not only is it not preferable in terms of workability, but also the probability that the shooting conditions differ for each acquired image, such as the shooting angle of each image being different, increases the overall image obtained finally. It can also be a factor that reduces accuracy.
[0006]
In view of the above circumstances, it is an object of the present invention to provide a method and apparatus capable of easily obtaining accurate game board image information.
[0007]

However, the height of attachment of the support frame body 60 to the leg portion 71a can be adjusted by expanding and contracting the elastic member 65. In this case, even if there is a slight error in the height at which the support frame 60 is fixed to the leg portion 71a by the locking piece 64, the image input surface 10a is larger than the game area C, and the image input surface 10a is a game. If the obstacle nail provided in the game area of the board B can be sufficiently read by the image scanner, a member whose length does not change can be used without using the elastic member 65.
[0020]
When the game area C is imaged by the gaming board reader 1 configured as described above, first, as shown in FIG. 4, the gantry 70 is appropriately traveled to open the glass frame F of the pachinko machine A, and the gantry 70. Is placed in front of the game board B. And each front-end | tip of the positioning pin 33 provided in the food | hood 30 is contact | abutted on the front surface of the game board B, respectively, Preferably it is outside a game area | region. At this time, the support frame 40 rotates horizontally with respect to the gantry 70, and the outer frame 21 of the image scanner 20 rotates appropriately vertically with respect to the support frame 40, so that the game board B is in any posture. The image input surface 10a of the image scanner 20 can be rotated in the vertical and horizontal directions, and the three positioning pins 33 can be brought into contact with the front surface of the game board B with certainty.
[0021]
Here, in a state where the three positioning pins 33 are in contact with the board surface of the game board B, the image input surface 10a of the image scanner 20 is parallel to the board surface of the game board B, and the obstacle nail D extends from the board surface of the game board B. To the tip of the reading unit 10 is positioned within the depth of field of the reading unit 10. Accordingly, the reading unit 10 is operated from this state, specifically, photoelectric conversion by the linear image sensor 13 is started with the light source 12 turned on, and the reading unit 10 is moved (scanned) by the driving means M. For example, it is possible to acquire a wide range of image information over the entire surface of the game area C (including a cell image and a failure nail D attached to the game board B) at a time.
[0022]
Then, when it is desired to adjust the displacement of the obstacle nail D based on the image information read by the image scanner 20, the U-shaped support frame 50 is rotated by the rotation shaft 50b, and the support frame 40 and the support frame The image scanner 20 and the like supported by the body 40 are moved together with the support frame body 40 toward the outside of the frame 70. Then, the adjustment operation of the obstacle nail D can be performed so that substantially the entire surface of the game board B of the pachinko machine A can be seen within the frame of the gantry 70.
[0023]
It should be noted that the image input surface 10a of the image scanner 20 does not necessarily have to be the entire size of the game area, and it is sufficient to scan only a necessary part.
[0024]
【The invention's effect】
As described above, according to the game board reading method of the present invention, it is not necessary to acquire a large number of images for one pachinko machine as in the case of applying a digital still camera, and the workability is improved. This is extremely advantageous.
Therefore, if the acquired image information is displayed on a display or the like as an image that can be visually recognized, and the planting state of the obstacle nail D is determined based on the displayed image, the management state based on the balance of the amusement store can be more accurately determined. You will be able to balance.
[0025]
Further, according to the game board reading device of the present invention, the image input surface of the image scanner is positioned and set in a predetermined game area of the game board of the pachinko machine, and the obstacle nail provided in the game area is read by the image scanner. Therefore, it is possible to acquire an accurate image with less distortion at a time over a wide range of the game board as compared with a digital still camera using a two-dimensional sensor. Therefore, for example, if a determination is made based on the acquired image, it is possible to easily grasp the more accurate installation state of the obstacle nail.
