Description

本発明は、スロットマシン機等のゲーム機の前面枠（前扉）を、本体枠（キャビネット）に対し施錠するゲーム機の施錠装置に関し、特に不正解錠を効果的に防止し、スムーズに施錠・解錠操作を行なうことができる施錠装置に関する。 The present invention relates to a locking device of a game machine that locks a front frame (front door) of a game machine such as a slot machine machine to a main body frame (cabinet), and in particular, effectively prevents unauthorized unlocking and smoothly locks the game machine. -It is related with the locking device which can perform unlocking operation.

従来、ゲーム機の施錠装置として、一般に、基枠体の内側に作動杆が摺動可能に配設され、基枠体の支持板の上部と下部に鉤部材が、作動杆に連結されて傾動可能に枢支され、基枠体の取付板の中間部に、シリンダ錠がその錠軸を取付板に設けた孔から内側に差し込むように固定され、錠軸の先端に作動杆と係合するカム板が取り付けられた構成の施錠装置が使用されている。 Conventionally, as a locking device of a game machine, an operating rod is generally slidably disposed inside a base frame body, and a hook member is connected to the upper and lower portions of the support plate of the base frame body and tilted by being connected to the operating rod. It is pivotally supported, and the cylinder lock is fixed to the middle part of the mounting plate of the base frame body so that the lock shaft is inserted inward from the hole provided in the mounting plate, and is engaged with the operating rod at the tip of the lock shaft. A locking device having a configuration in which a cam plate is attached is used.

この種のゲーム機用施錠装置は、構造が強固で、施錠・解錠動作も確実に行うことができるものの、針金などで不正に操作された場合、不正解錠が行なわれる可能性があった。すなわち、ゲーム機の前面枠を不正に解錠するために、ゲーム機の前面枠と本体枠の隙間から針金などを差し込み、針金の先端で作動杆を係止して作動杆を解錠方向に動かした場合、作動杆の移動と共に、上下の鉤部材が解錠方向に傾動し、不正に解錠される虞があった。 This type of game machine locking device has a strong structure and can perform locking and unlocking operations with certainty. However, if it is illegally operated with a wire or the like, it may be unlocked. . In other words, in order to unlock the front frame of the game machine illegally, insert a wire etc. through the gap between the front frame of the game machine and the main body frame, and lock the operating rod with the tip of the wire to unlock the operating rod in the unlocking direction. When moved, the upper and lower hook members may tilt in the unlocking direction along with the movement of the operating hook, and there is a possibility that the unlocking may be illegally unlocked.

そこで、このような不正解錠を防止するために、従来、下部または上部の何れか一方の鉤部材が、不正針金などにより解錠方向に傾動された場合でも、他方の鉤部材は解錠方向に従動せずに、施錠状態を保持するようにして、不正解錠を防止する施錠装置が、下記特許文献１などで提案されている。
特開２００１−３４２７６２号公報 Therefore, conventionally, in order to prevent such unauthorized unlocking, even when either the lower or upper saddle member is tilted in the unlocking direction by an illegal wire or the like, the other saddle member is in the unlocking direction. Patent Document 1 below proposes a locking device that prevents unauthorized unlocking by keeping a locked state without being driven.
JP 2001-342762 A

しかしながら、従来のこの種の不正解錠を防止する施錠装置であっても、施錠状態において、上部と下部の鉤部材は物理的に解錠方向に傾動可能な状態となっているため、上部の鉤部材と下部の鉤部材の両方に不正な針金などを同時に引っ掛けて、解錠方向に引いて傾動させた場合には、不正解錠が可能となってしまい、非常に少ない確率ながら、やはり不正解除が行なわれる虞があった。 However, even in a conventional locking device that prevents this type of unauthorized unlocking, the upper and lower hook members are physically tiltable in the unlocking direction in the locked state. If an illegal wire or the like is hooked on both the heel member and the lower heel member at the same time and is pulled and tilted in the unlocking direction, unauthorized unlocking becomes possible, and although there is very little probability, it is also illegal. There was a risk of release.

本発明は、上記の点に鑑みてなされたもので、針金などを用いた不正解錠を完全に防止することができ、施錠・解錠操作もスムーズに行なうことができるゲーム機の施錠装置を提供することを目的とする。 The present invention has been made in view of the above points, and provides a locking device for a game machine that can completely prevent unauthorized unlocking using a wire or the like, and that can smoothly perform locking and unlocking operations.

さらに、請求項５のように、前記基枠体の内側にカバーガイド部材が該カム部材を覆って取り付けられ、該カバーガイド部材には、該カム部材の回動と錠軸の軸方向の移動をガイドする異形ガイド孔が形成されると共に、該カム部材を施錠位置に係止して該シリンダ錠の解錠側への移動を阻止する係止部が該カム部材に設けられた構成とすることができる。 Furthermore, as in claim 5, a cover guide member is attached to the inside of the base frame body so as to cover the cam member, and the cam member rotates and moves in the axial direction of the lock shaft. The cam member is formed with a locking portion for locking the cam member to the locking position and preventing the cylinder lock from moving to the unlocking side. be able to.

さらに、請求項６のように、前記カバーガイド部材の異形ガイド孔は、シリンダ錠にキーを差し込んで錠軸を解除側に回したとき、前記カム部材との係止が外れてシリンダ錠の引き出し動作を可能とする形状に形成され、該カム部材の軸方向の移動をガイドする係合ガイド部が該異形ガイド孔に設けられた構成とすることができる。 Further, as described in claim 6, when the key is inserted into the cylinder lock and the lock shaft is turned to the release side, the deformed guide hole of the cover guide member is disengaged from the cam member and pulled out of the cylinder lock. It is possible to adopt a configuration in which an engagement guide portion that is formed in a shape that enables operation and guides the movement of the cam member in the axial direction is provided in the deformed guide hole.

さらに、請求項７のように、前記シリンダ錠の錠軸またはカム部材に、キー挿入可能な中立位置に戻すための捻りばねが装着され、施錠時にシリンダ錠を押し込んだ際、該錠軸及びカム部材が該捻りばねの付勢力により中立位置に戻る構成とすることができる。 Further, as in claim 7, a torsion spring for returning to the neutral position where the key can be inserted is attached to the lock shaft or cam member of the cylinder lock, and when the cylinder lock is pushed in during locking, the lock shaft and cam The member can be configured to return to the neutral position by the biasing force of the torsion spring.

さらに、請求項８のように、前記シリンダ錠の元部にフランジが設けられ、該フランジに前記係止部材が固定され、前記カバーガイド部材の内側に複数のガイド筒が該シリンダ錠の軸方向に沿って設けられ、該フランジが該ガイド筒に摺動可能にガイドされる構成とすることができる。 Further, as in claim 8, a flange is provided at the base of the cylinder lock, the locking member is fixed to the flange, and a plurality of guide cylinders are arranged in the axial direction of the cylinder lock inside the cover guide member. The flange can be slidably guided by the guide tube.

上記構成の施錠装置は、前面枠をキャビネットに対し閉じると、受け金具がラッチ部材の拘束溝部内に進入し、受け金具がラッチ部材を押し込むようにしてラッチ部材がばね手段の付勢力に抗して回動し、ラッチ部材の拘束溝部内に受け金具が拘束された状態となる。この時、シリンダ錠が手動により或はばね部材の付勢力により基枠体に押し込まれ、ロック手段としての係止部材が作動杆を施錠位置にロックして、作動杆及びラッチ部材を施錠状態にロックする。受け金具はラッチ部材の拘束溝部内にロックされ施錠状態となる。 In the locking device having the above configuration, when the front frame is closed with respect to the cabinet, the receiving member enters the restraining groove of the latch member, and the receiving member pushes the latch member so that the latch member resists the biasing force of the spring means. And the bracket is restrained in the restraining groove of the latch member. At this time, the cylinder lock is pushed into the base frame manually or by the urging force of the spring member, and the locking member as the locking means locks the operating rod in the locking position, and puts the operating rod and the latch member in the locked state. Lock it. The catch is locked in the restraining groove of the latch member and is locked.

このように、施錠状態においては、係止部材が作動杆及びラッチ部材を施錠位置にロックするため、その移動や回動が不可能となり、不正な針金を前面枠の隙間から差し込んで、作動杆、ラッチ部材を動かして不正解除しようとしても、動かすことができず、完全に近い確率で不正解錠を防止することができる。 In this way, in the locked state, the locking member locks the operating rod and the latch member in the locked position, so that the movement and rotation of the locking member becomes impossible, and an illegal wire is inserted through the gap in the front frame, Even if the latch member is moved for unauthorized release, it cannot be moved, and unauthorized unlocking can be prevented with almost perfect probability.

また、解錠する場合は、シリンダ錠のキーを回し、且つシリンダ錠を基枠体から引き出すように操作する。これにより、シリンダ錠と共に係止部材が移動して作動杆のロックが解除され、ばね部材の付勢力により作動杆が解錠方向に移動し、ラッチ部材が解錠側に回動する。このとき、ラッチ部材はばね部材の付勢力により解錠方向に付勢されているため、ばね力により自動的に解錠位置に回動し、ロックされていた受け金具がラッチ部材の拘束溝部から外れ、前方に押し出され、解錠状態となる。 When unlocking, the key of the cylinder lock is turned and the cylinder lock is pulled out from the base frame. As a result, the locking member moves together with the cylinder lock, the lock of the operating rod is released, the operating rod moves in the unlocking direction by the biasing force of the spring member, and the latch member rotates to the unlocking side. At this time, since the latch member is urged in the unlocking direction by the urging force of the spring member, the latch member is automatically rotated to the unlocking position by the spring force, and the locked metal fitting is released from the restraining groove portion of the latch member. Detached, pushed forward, and unlocked.

このとき、ラッチ部材はばね部材により付勢されて解錠位置まで回動し、受け金具を押し出すように作用するため、固定側の受け金具から反動を受けて、前面枠が自動的に開き、使用者は解錠したことを容易に認識することができる。また、施錠操作は、使用者が例えばキーを持って前面枠を閉じると共に、同時にシリンダ錠を押し込むだけの簡単な操作で、或はシリンダ錠がばね部材により押し込む方向に付勢されている場合は、前面枠を閉じるだけの簡単な操作で、施錠することができる。また、解錠時にも、キーを回してシリンダ錠を引けば、シリンダ錠がそのまま引き出されて解錠されるため、極めてスムーズに施錠・解錠を行うことができる。 At this time, the latch member is urged by the spring member to rotate to the unlocked position and acts to push out the receiving bracket, so that the front frame is automatically opened by receiving a reaction from the receiving bracket on the fixed side, The user can easily recognize the unlocking. In addition, the locking operation is a simple operation in which the user closes the front frame with, for example, a key and simultaneously pushes in the cylinder lock, or when the cylinder lock is urged in the pushing direction by a spring member. It can be locked with a simple operation just by closing the front frame. Further, when unlocking, if the cylinder lock is pulled by turning the key, the cylinder lock is pulled out and unlocked as it is, so that the lock and unlock can be performed very smoothly.

また、図８に示すように、係止部材１０の取付部１０ｂには、シリンダ錠９を軸方向に移動可能にガイドする２本のガイド筒１５を通すためのガイド孔１０ｃが穿設され、さらに、中央には、錠軸９ｂを位置させると共に、錠軸９ｂの周りに捻りばね１４を装着するための円形凹部が形成されている。このような係止部材１０は、その取付部１０ｂがシリンダ錠９のフランジ９ａの正面側に固定されるが、さらにその取付部１０ｂの正面側には図９に示すようなカバー部材１１が固定ねじなどで固定される。このカバー部材１１にも、係止部材１０の取付部１０ｂと同様のガイド孔１１ｃと円形凹部が形成されている。シリンダ錠９が基枠体１に装着されたとき、係止部材１０の係止部１０ａは取付板２の幅広部２ａの角部に設けたスリット孔２ｃに挿入され、シリンダ錠９の摺動に応じてそのスリット孔２ｃ内を移動する。 Further, as shown in FIG. 8, a guide hole 10 c for passing two guide cylinders 15 that guide the cylinder lock 9 so as to be movable in the axial direction is formed in the mounting portion 10 b of the locking member 10. Furthermore, a circular recess is formed at the center for positioning the lock shaft 9b and for mounting the torsion spring 14 around the lock shaft 9b. Such a locking member 10 has a mounting portion 10b fixed to the front side of the flange 9a of the cylinder lock 9, and a cover member 11 as shown in FIG. 9 is fixed to the front side of the mounting portion 10b. It is fixed with screws. The cover member 11 is also formed with a guide hole 11c and a circular recess similar to the attachment portion 10b of the locking member 10. When the cylinder lock 9 is mounted on the base frame body 1, the locking portion 10 a of the locking member 10 is inserted into the slit hole 2 c provided at the corner of the wide portion 2 a of the mounting plate 2, and the cylinder lock 9 slides. In response to the movement in the slit hole 2c.

なお、カバー部材１１は、係止部材１０と一体に形成することもできる。また、係止部材１０は、或はカバー部材１１と一体化された係止部材は、シリンダ錠９のフランジ９ａと一体に形成することもできる。 The cover member 11 can be formed integrally with the locking member 10. Further, the locking member 10 or the locking member integrated with the cover member 11 can be formed integrally with the flange 9 a of the cylinder lock 9.

シリンダ錠９のフランジ９ａの正面側に係止部材１０とカバー部材１１が固定された状態で、その中央に突出する錠軸９ｂの周りに捻りばね１４が装着され、その上から図１２のようにカム部材１３が固定ねじより錠軸９ｂの先端部に固定される。カム部材１３は、図１１に示すように、中央の円形部の２箇所にばね掛け部１３ｆ、１３ｇが突設され、円形部の背面側に突出して第１ガイド部１３ａと第２ガイド部１３ｂが設けられ、第１ガイド部１３ａの外側にはスイッチ作動部１３ｅが外方に突き出すように設けられる。 With the locking member 10 and the cover member 11 fixed to the front side of the flange 9a of the cylinder lock 9, a torsion spring 14 is mounted around the lock shaft 9b protruding in the center, as shown in FIG. Further, the cam member 13 is fixed to the distal end portion of the lock shaft 9b by a fixing screw. As shown in FIG. 11, the cam member 13 has spring hook portions 13f and 13g projecting at two locations in the central circular portion, projecting to the back side of the circular portion, and a first guide portion 13a and a second guide portion 13b. The switch actuating portion 13e is provided outside the first guide portion 13a so as to protrude outward.

このカム部材１３は、従来の施錠装置のように連結杆或いは作動杆に作用して、鉤部材を回動或は摺動させるためのものではなく、解錠状態においてシリンダ錠９の錠軸９ｂの動きをロックし、シリンダ錠９を押し込んだ施錠状態においてその押し込み状態をロックするための係止部材として機能する部材であり、また、第１ガイド部１３ａに設けられたスイッチ作動部１３ｅのように、スイッチ作動部材として機能する部材である。カム部材１３の２箇所のばね掛け部１３ｆ、１３ｇには、上記捻りばね１４の両端が掛止され、錠軸９ｂとカム部材１１は、この捻りばね１４によって、その中立位置に常に戻されるように付勢される。 The cam member 13 does not act on the connecting rod or the actuating rod as in the conventional locking device to rotate or slide the rod member, but the lock shaft 9b of the cylinder lock 9 in the unlocked state. Is a member that functions as a locking member for locking the pushed state in the locked state in which the cylinder lock 9 is pushed in, and is like a switch operating part 13e provided in the first guide part 13a. In addition, the member functions as a switch operating member. Both ends of the torsion spring 14 are hooked to the two spring hook portions 13f and 13g of the cam member 13, so that the lock shaft 9b and the cam member 11 are always returned to their neutral positions by the torsion spring 14. Be energized by.

カム部材１３は、その第１ガイド部１３ａと第２ガイド部１３ｂが、シリンダ錠９の軸方向への摺動時に、後述のカバーガイド部材１２の異形ガイド孔１２ａ内を摺動して、その摺動をガイドするように作用する。また、図１１（ｂ）に示すように、第１ガイド部１３ａの元部には係止部１３ｃが段状に形成され、第２ガイド部１３ｂの元部には係止部１３ｄが段状に形成され、施錠時にシリンダ錠９が押し込まれ、錠軸９ａが中立位置に戻されたとき、係止部１３ｃ、１３ｄがカバーガイド部材１２の背面側に係止され、施錠係止状態を保持する。 The cam member 13 slides in a deformed guide hole 12a of a cover guide member 12 described later when the first guide portion 13a and the second guide portion 13b slide in the axial direction of the cylinder lock 9. It acts to guide the sliding. Further, as shown in FIG. 11B, a locking portion 13c is formed in a step shape at the base portion of the first guide portion 13a, and a locking portion 13d is formed in a step shape at the base portion of the second guide portion 13b. When the cylinder lock 9 is pushed in and the lock shaft 9a is returned to the neutral position, the locking portions 13c and 13d are locked to the back side of the cover guide member 12, and the locking lock state is maintained. To do.

また、解錠時にキーを右に回してシリンダ錠９を引き出したとき、図１５（ｂ）のように、カム部材１３の第１ガイド部１３ａと第２ガイド部１３ｂが、カバーガイド部材１２の異形ガイド孔１２ａ内の上下の係合ガイド部１２ｂに嵌合し、その状態を保持する構造となっている。つまり、シリンダ錠９にキーを挿入して解錠位置に回し、シリンダ錠９を引き出したとき、この第１ガイド部１３ａと第２ガイド部１３ｂが係合ガイド部１２ｂに嵌合して、キーの回動状態を保持するようにしている。 Further, when the cylinder lock 9 is pulled out by turning the key to the right during unlocking, the first guide portion 13a and the second guide portion 13b of the cam member 13 are connected to the cover guide member 12 as shown in FIG. The structure is such that the upper and lower engagement guide portions 12b in the deformed guide hole 12a are fitted and held in this state. That is, when the key is inserted into the cylinder lock 9 and turned to the unlocking position and the cylinder lock 9 is pulled out, the first guide portion 13a and the second guide portion 13b are fitted into the engagement guide portion 12b, and the key The rotation state is maintained.

基枠体１内の取付板２の幅広部２ａには、その背面側からシリンダ錠９のフランジ９ａ、カバー部材１１、係止部材１０を覆うようにカバーガイド部材１２が固定される。カバーガイド部材１２は、図１０に示すように、側面視で略コ字状に形成され、背面側の中央に異形ガイド孔１２ａが形成され、その上部と下部には２本のガイド筒１５に各々固定ねじ１６を挿入するための挿入孔が形成されている。この異形ガイド孔１２ａには背面側からカム部材１３が挿入され、カム部材１３はその中央に固定ねじが差し込まれ錠軸９ｂに固定される。異形ガイド孔１２ａには、カム部材１３を図１２（ｂ）の位置にキーを回して回動したとき、カム部材１３の第１ガイド部１３ａとガイド部１３ｂを係合させてガイドする係合ガイド部１２ｂが上部と下部に平坦部分として形成されている。 A cover guide member 12 is fixed to the wide portion 2a of the mounting plate 2 in the base frame 1 so as to cover the flange 9a, the cover member 11, and the locking member 10 of the cylinder lock 9 from the back side. As shown in FIG. 10, the cover guide member 12 is formed in a substantially U shape in a side view, and a deformed guide hole 12 a is formed in the center on the back side, and two guide cylinders 15 are formed at the upper part and the lower part. Insertion holes for inserting the fixing screws 16 are formed. A cam member 13 is inserted into the deformed guide hole 12a from the back side, and a fixing screw is inserted into the center of the cam member 13 and fixed to the lock shaft 9b. When the cam member 13 is rotated to the position shown in FIG. 12B by turning the key to the deformed guide hole 12a, the first guide portion 13a and the guide portion 13b of the cam member 13 are engaged and guided. Guide portions 12b are formed as flat portions at the upper and lower portions.

係止部材１０及びガイド部材１１をフランジ９ａに固定したシリンダ錠９を、基枠体１に取り付ける場合、図５に示すように、フランジ９ａなどの上部と下部に設けたガイド孔９ｃ、１０ｃ、１１ｃに２本のガイド筒１５を挿入した状態で、シリンダ錠９を基枠体１の内側からその幅広部２ａの挿入孔に差し込む。次に、カバーガイド部材１２をフランジ９ａ等の背面側に被せ、固定ねじ１６を挿入孔からガイド筒１５内に差し込み、幅広部２ａのねじ孔にねじ込み、カバーガイド部材１２を固定する。 When the cylinder lock 9 in which the locking member 10 and the guide member 11 are fixed to the flange 9a is attached to the base frame 1, as shown in FIG. 5, guide holes 9c, 10c provided in the upper and lower portions of the flange 9a, etc. With the two guide cylinders 15 inserted into 11c, the cylinder lock 9 is inserted into the insertion hole of the wide portion 2a from the inside of the base frame 1. Next, the cover guide member 12 is put on the back side of the flange 9a and the like, the fixing screw 16 is inserted into the guide tube 15 through the insertion hole, and is screwed into the screw hole of the wide portion 2a to fix the cover guide member 12.

これにより、シリンダ錠９は係止部材１０、カバー部材１１、カム部材１３と共にその軸方向に摺動可能に、つまり基枠体1に対し押しこみ引き出し可能に装着され、係止部材１０、カバー部材１１、カム部材１３はカバーガイド部材１２の内側で前後方向に移動可能に組み付けられる。 Thus, the cylinder lock 9 is mounted together with the locking member 10, the cover member 11, and the cam member 13 so as to be slidable in the axial direction thereof, that is, to be able to be pushed out and pulled out from the base frame 1, The member 11 and the cam member 13 are assembled inside the cover guide member 12 so as to be movable in the front-rear direction.

なお、基枠体１の支持板３の下部には、滑りローラ１７が回転可能に軸支され、中間支持板３ｅの外側には、作動スイッチを取り付けるための取付ブラケット１８が固定されている。取付ブラケット１８には、図示しない光電スイッチなどからなる非接触スイッチが取り付けられ、シリンダ錠９に差し込んだキーを左側に回したとき、カム部材１３が同方向に回動し、そのスイッチ作動部１３ｅが非接触スイッチの内側に進入し、スイッチ信号が発生する。 A sliding roller 17 is rotatably supported at the lower portion of the support plate 3 of the base frame 1, and a mounting bracket 18 for attaching an operation switch is fixed to the outside of the intermediate support plate 3 e. A non-contact switch such as a photoelectric switch (not shown) is attached to the mounting bracket 18, and when the key inserted into the cylinder lock 9 is turned to the left, the cam member 13 is rotated in the same direction, and the switch operating portion 13e. Enters the inside of the non-contact switch and a switch signal is generated.

このように構成された施錠装置は、図１８，図１９に示すように、ゲーム機の前扉（前面枠）２１の内側にその取付板２を当てて固定され、キャビネット（本体枠）２０の内側の対応位置には、受け金具２２，２３が取り付けられる。なお、受け金具は１本の受け金具本体に２個の係止部を設けて形成することもできる。 As shown in FIGS. 18 and 19, the locking device configured in this manner is fixed by placing the mounting plate 2 inside the front door (front frame) 21 of the game machine, and the cabinet (main body frame) 20. Receiving brackets 22 and 23 are attached to the inner corresponding positions. In addition, a receiving metal fitting can also be formed by providing two locking portions on one receiving metal fitting body.

受け金具２２，２３は、金属板をＬ形に曲折して形成され、板状の係止部を施錠装置側のラッチ部材５、６に対向し、正面を向くように取り付けられ、その板状の係止部はラッチ部材５，６の拘束溝部に進入し嵌合可能である。また、キャビネット２０の下部にはローラ受け２４が滑りローラ１７に対応した位置に取り付けられる。 The metal fittings 22 and 23 are formed by bending a metal plate into an L shape, and are attached so that the plate-like locking portions face the latch members 5 and 6 on the locking device side and face the front. The engaging portion can enter and be engaged with the restraining groove portion of the latch members 5 and 6. A roller receiver 24 is attached to a lower portion of the cabinet 20 at a position corresponding to the sliding roller 17.

前扉２１を開いた状態では、図１８のように、施錠装置は解錠状態にあり、図１６に示すように、シリンダ錠９は正面側に引き出され、これによって、係止部材１０の係止部１０ａが上部作動杆７と下部作動杆８の係止凸部７ａ，８ａから外れ、上部作動杆７と下部作動杆８はコイルばね４に付勢力によりカム部材側（中央側）に移動し、つまり上部作動杆７が下に移動して、上部のラッチ部材５が解錠状態となり、下部作動杆８が上に移動して、下部のラッチ部材６が解錠状態となっている。すなわち、コイルばね４の付勢力により、上部作動杆７は下方に移動した状態、下部作動杆８は上方に移動した状態となる。また、上部のラッチ部材５は背面側に開いて、その拘束溝部５ａを斜め下方に向け、下部のラッチ部材６は背面側に開いて、その拘束溝部６ａを斜め上方に向け、シリンダ錠９は正面側に引き出された状態となっている。 When the front door 21 is opened, the locking device is unlocked as shown in FIG. 18, and the cylinder lock 9 is pulled out to the front side as shown in FIG. The stop portion 10a is disengaged from the locking projections 7a and 8a of the upper operating rod 7 and the lower operating rod 8, and the upper operating rod 7 and the lower operating rod 8 move to the cam member side (center side) by the biasing force of the coil spring 4. That is, the upper operating rod 7 is moved downward, the upper latch member 5 is unlocked, the lower operating rod 8 is moved upward, and the lower latch member 6 is unlocked. That is, due to the biasing force of the coil spring 4, the upper operating rod 7 is moved downward and the lower operating rod 8 is moved upward. Further, the upper latch member 5 opens to the back side, the restraining groove portion 5a faces obliquely downward, the lower latch member 6 opens to the back side, the restraining groove portion 6a faces obliquely upward, and the cylinder lock 9 It is in the state pulled out to the front side.

なお、この解錠状態におけるシリンダ錠９は、図１５（ｂ）のように、その錠軸９ｂに固定されたカム部材１３の第１ガイド部１３ａと第２ガイド部１３ｂが、カバーガイド部材１２の異形ガイド孔１２ａ内の上下の係合ガイド部１２ｂに嵌合しているため、キーを右に回した状態で保持されている。つまり、通常のシリンダ錠を使用した場合、このようにキーを中立位置から回した状態では、キーを抜くことができないため、キーはキーを右に回した状態で保持される。 As shown in FIG. 15B, the cylinder lock 9 in this unlocked state includes the first guide portion 13a and the second guide portion 13b of the cam member 13 fixed to the lock shaft 9b. Since the upper and lower engagement guide portions 12b in the deformed guide hole 12a are fitted, the key is held in a state where the key is turned to the right. That is, when a normal cylinder lock is used, since the key cannot be removed when the key is turned from the neutral position in this way, the key is held with the key turned to the right.

ゲーム機が、図１８のように、前面枠２１を開いた状態において、前面枠２１を施錠する場合には、それを閉じて施錠するが、このとき、シリンダ錠９に差し込んだキーは解錠位置（右に回した位置）にロックされているから、使用者はキーを持った状態で、前面枠２１を押して閉じることができる。 When the game machine locks the front frame 21 with the front frame 21 open as shown in FIG. 18, the game machine is closed and locked. At this time, the key inserted into the cylinder lock 9 is unlocked. Since it is locked in the position (position turned to the right), the user can close the front frame 21 by pushing it with the key.

そして、図１９のように、前面枠２１をキャビネット２０側に閉じると、上下のラッチ部材５，６が、受け金具２２，２３の押し込み力を受けて相互に内側に回動しながら、その拘束溝部５ａ，６ａ内に受け金具２２，２３の板部が進入し、ラッチ部材５，６の拘束溝部５ａ，６ａが略真下または真上に向いたとき、完全にロックされた状態となる。このとき、図１５のように、上部作動杆７は上方に移動してその下部の係止凸部７ａは上にシフトし、下部作動杆８は下方に移動してその上部の係止凸部８ａは下にシフトするため、シリンダ錠９と共に軸方向に移動可能な係止部材１０は押し込み可能な状態となる。 Then, as shown in FIG. 19, when the front frame 21 is closed to the cabinet 20 side, the upper and lower latch members 5 and 6 receive the pushing force of the receiving brackets 22 and 23 and rotate to the inside to restrain each other. When the plate portions of the receiving fittings 22 and 23 enter the groove portions 5a and 6a and the restraining groove portions 5a and 6a of the latch members 5 and 6 are directed substantially directly below or directly above, they are completely locked. At this time, as shown in FIG. 15, the upper operating rod 7 moves upward and the lower locking projection 7a shifts upward, and the lower operating rod 8 moves downward and the upper locking projection 7a. Since 8a shifts downward, the locking member 10 that is movable in the axial direction together with the cylinder lock 9 is in a pushable state.

このため、使用者はキーを持った状態で、前面枠２１を押し込んで閉じたとき、押し込み力がシリンダ錠９にそのまま作用し、図１４のように、シリンダ錠９が基枠体１に押し込まれる。このとき、シリンダ錠９のフランジ９ａに固定された係止部材１０の係止部１０ａが、上部作動杆７の係止凸部７ａと下部作動杆８の係止凸部８ａの間に進入し、係止凸部７ａ，８ａが上下の係止部１０ａに係止される。よって、上部作動杆７と下部作動杆８及び上下のラッチ部材５，６がロックされ、施錠状態となる。 Therefore, when the user holds the key and pushes in and closes the front frame 21, the pushing force acts on the cylinder lock 9 as it is, and the cylinder lock 9 is pushed into the base frame 1 as shown in FIG. It is. At this time, the locking portion 10 a of the locking member 10 fixed to the flange 9 a of the cylinder lock 9 enters between the locking convex portion 7 a of the upper operating rod 7 and the locking convex portion 8 a of the lower operating rod 8. The locking projections 7a and 8a are locked to the upper and lower locking portions 10a. Therefore, the upper operating rod 7, the lower operating rod 8, and the upper and lower latch members 5 and 6 are locked and become locked.

また、このとき、カム部材１３は、図１３（ａ）のように、カバーガイド部材１２の異形ガイド孔１２ａの背面側に押し込まれ、左に回動可能な状態となるため、シリンダ錠９に差し込んだキーは、その錠軸９とカム部材１３は、捻りばね１４の付勢力によって、自動的に中立位置に戻される。そして、錠軸９とカム部材１３が、図１４のような中立位置に回動した状態では、図１３に示すように、カム部材１３の係止部１３ｃ、１３ｄがカバーガイド部材１２の背面に係止されるため、カム部材１３とシリンダ錠９はその位置でロックされる。したがって、この状態で、施錠は完了し、使用者は中立位置のシリンダ錠９からキーを抜くことができる。 Further, at this time, as shown in FIG. 13A, the cam member 13 is pushed into the back side of the deformed guide hole 12a of the cover guide member 12 and is turned to the left. As for the inserted key, the lock shaft 9 and the cam member 13 are automatically returned to the neutral position by the biasing force of the torsion spring 14. When the lock shaft 9 and the cam member 13 are rotated to the neutral position as shown in FIG. 14, the locking portions 13 c and 13 d of the cam member 13 are located on the back surface of the cover guide member 12 as shown in FIG. 13. Since it is locked, the cam member 13 and the cylinder lock 9 are locked at that position. Therefore, in this state, locking is completed and the user can remove the key from the cylinder lock 9 in the neutral position.

このように、施錠操作は、使用者が例えばキーを持って前面枠２１を閉じると共に、同時にシリンダ錠９を押し込むだけの簡単な操作で施錠することができる。また、このような施錠状態においては、図１４に示すように、係止部材１０の上下の係止部１０ａが上部作動杆７の係止凸部７ａと下部作動杆８の係止凸部８ａに係止されて、上部作動杆７と下部作動杆８及び上下のラッチ部材５，６が、完全にロックされ、その移動や回動が不可能となるため、不正な針金を差し込んで、上部作動杆７、下部作動杆８、ラッチ部材５，６を動かして不正解除しようとしても、全く不可能となる。 Thus, the locking operation can be locked by a simple operation in which the user closes the front frame 21 with a key, for example, and simultaneously pushes in the cylinder lock 9. Further, in such a locked state, as shown in FIG. 14, the upper and lower locking portions 10 a of the locking member 10 are locked to the locking projections 7 a of the upper actuation rod 7 and the locking projections 8 a of the lower actuation rod 8. The upper operating rod 7 and the lower operating rod 8 and the upper and lower latch members 5 and 6 are completely locked and cannot be moved or rotated. Even if the actuating rod 7, the lower actuating rod 8, and the latch members 5 and 6 are moved to try to release them illegally, it becomes impossible at all.

また、施錠状態においては、図１９のように、上下のラッチ部材５，６が間に受け金具２２，２３を挟むようにロックされるため、仮に前面枠２１を上下方向に動かして不正にラッチ部材５，６の係止を外そうとしても、不正解錠は不可能となる。さらに、ゲーム機の前面枠２１は通常、その左端部に蝶番が取り付けられ、前面枠２１の右側端部に施錠装置が縦に取り付けられ、その場合、前面枠の自由端側の隙間に近い施錠装置の部分は、基枠体１の内側となるが、不正解錠の際に不正操作されやすい上部作動杆７、下部作動杆８、ラッチ部材５，６、及びコイルばね４は、基枠体１の外側に配設されるため、これによっても、不正解除を解消することができる。 Further, in the locked state, as shown in FIG. 19, since the upper and lower latch members 5 and 6 are locked so as to sandwich the metal fittings 22 and 23 therebetween, the front frame 21 is temporarily moved up and down to be illegally latched. Even if the members 5 and 6 are unlocked, unauthorized unlocking is impossible. Further, the front frame 21 of the game machine is usually provided with a hinge at the left end thereof, and a locking device is vertically installed at the right end portion of the front frame 21. In this case, the locking is close to the clearance on the free end side of the front frame. The portion of the device is inside the base frame body 1, but the upper operating rod 7, the lower operating rod 8, the latch members 5 and 6, and the coil spring 4 that are easily manipulated during unauthorized unlocking are composed of the base frame body. Since it is disposed outside of 1, the unauthorized release can be resolved also by this.

一方、施錠装置を解錠操作する場合は、キーをシリンダ錠９に挿入し、それを右側に回す。すると、図１５に示すように、錠軸、カム部材１３が捻りばね１４の付勢力に抗して同方向に回動し、カム部材１３の第１ガイド部１３ａと第２ガイド部１３ｂがカバーガイド部材１２の異形ガイド孔１２ａの係止ガイド部１２ｂに沿った位置に回動したとき、カム部材１３及びシリンダ錠９が軸方向に移動可能となる。そしてその状態でキーを持ってシリンダ錠９を手前に引き出すように操作する。 On the other hand, when unlocking the locking device, the key is inserted into the cylinder lock 9 and turned to the right. Then, as shown in FIG. 15, the lock shaft and the cam member 13 rotate in the same direction against the urging force of the torsion spring 14, and the first guide portion 13a and the second guide portion 13b of the cam member 13 cover the cover. When the guide member 12 is rotated to a position along the locking guide portion 12b of the deformed guide hole 12a of the guide member 12, the cam member 13 and the cylinder lock 9 are movable in the axial direction. In this state, the user holds the key and operates to pull out the cylinder lock 9 toward the front.

このとき、図１５（ａ）のように、シリンダ錠９と共に係止部材１０が前方に引き出され、これにより、係止部材１０の係止部１０ａが上部作動杆７と下部作動杆８の係止凸部７ａ，８ａから外れる。このため、図１６のように、上部作動杆７と下部作動杆８は、コイルばね４の付勢力によりカム部材側（中央側）に移動し、つまり上部作動杆７が下に移動して、上部のラッチ部材５が解錠状態となり、下部作動杆８が上に移動して、下部のラッチ部材６が解錠状態となる。すなわち、コイルばね４の付勢力により、上部作動杆７は下方に移動し、下部作動杆８は上方に移動した状態となる。よって、上部のラッチ部材５は背面側に開いてその拘束溝部５ａを斜め下方に向けるように回動し、下部のラッチ部材６は背面側に開いてその拘束溝部６ａを斜め上方に向けるように回動し、これによって、受け金具２２，２３はラッチ部材５，６から突き出すように開放され、解錠される。 At this time, as shown in FIG. 15A, the locking member 10 is pulled forward together with the cylinder lock 9, whereby the locking portion 10 a of the locking member 10 is engaged with the upper operating rod 7 and the lower operating rod 8. Detach from the stop protrusions 7a, 8a. For this reason, as shown in FIG. 16, the upper operating rod 7 and the lower operating rod 8 are moved to the cam member side (center side) by the biasing force of the coil spring 4, that is, the upper operating rod 7 is moved downward, The upper latch member 5 is unlocked, the lower operating rod 8 is moved upward, and the lower latch member 6 is unlocked. That is, the upper operating rod 7 moves downward and the lower operating rod 8 moves upward due to the biasing force of the coil spring 4. Accordingly, the upper latch member 5 is opened to the rear side and rotated so that the restraining groove portion 5a faces obliquely downward, and the lower latch member 6 is opened to the rear side so that the restraining groove portion 6a faces obliquely upward. As a result, the receiving brackets 22 and 23 are opened so as to protrude from the latch members 5 and 6 and unlocked.

また、このとき、ラッチ部材５、６は、コイルばね４により解錠位置まで付勢されて回動するため、固定側の受け金具２２，２３をラッチ部材５、６が押した反動で、施錠装置側の前面枠２１が自動的に開き、使用者は解錠したことを容易に認識することができる。そしてこのとき、シリンダ錠９は、上記のように、正面側に引き出され、右に所定角度だけ回した状態に保持される。 At this time, since the latch members 5 and 6 are urged to the unlocked position by the coil spring 4 and rotate, the locking members 22 and 23 on the fixed side are rebounded by the latch members 5 and 6 and locked. The front frame 21 on the apparatus side automatically opens, and the user can easily recognize that the device has been unlocked. At this time, the cylinder lock 9 is pulled out to the front side as described above, and is held in a state where it is turned to the right by a predetermined angle.

一方、施錠状態において、シリンダ錠９にキーを差し込み、左に回すと、カム部材１３が同方向に回動して図１２（ｃ）の状態となる。このとき、その第１ガイド部１３ａ上のスイッチ作動部１３ｅが、取付ブラケット１８上の図示しない非接触スイッチに作用し、非接触スイッチからオンオフ信号がリセット信号などとして出力され、リセット操作などに使用される。 On the other hand, in the locked state, when the key is inserted into the cylinder lock 9 and turned to the left, the cam member 13 rotates in the same direction, and the state shown in FIG. At this time, the switch operating portion 13e on the first guide portion 13a acts on a non-contact switch (not shown) on the mounting bracket 18, and an on / off signal is output as a reset signal from the non-contact switch, which is used for a reset operation or the like. Is done.

このように、施錠状態においては、係止部材１０の上下の係止部１０ａが上部作動杆７の係止凸部７ａと下部作動杆８の係止凸部８ａに係止されて、上部作動杆７と下部作動杆８及び上下のラッチ部材５，６が、完全にロックされ、その移動や回動が不可能となる。したがって、不正な針金を前面枠の隙間から差し込んで、上部作動杆７、下部作動杆８、ラッチ部材５，６を動かして不正解除しようとしても、全く不可能となり、非常に高い確率で不正解錠を防止することができる。また、施錠操作は、使用者が例えばキーを持って前面枠２１を閉じると共に、同時にシリンダ錠９を押し込むだけの簡単な操作で施錠することができ、解錠時にも、キーを回してシリンダ錠９を引けば、シリンダ錠９がそのまま引き出されて解錠されるため、極めてスムーズに施錠解錠操作を行うことができる。 Thus, in the locked state, the upper and lower engaging portions 10a of the engaging member 10 are engaged with the engaging projection 7a of the upper operating rod 7 and the engaging convex portion 8a of the lower operating rod 8, and the upper operation is performed. The rod 7, the lower operating rod 8, and the upper and lower latch members 5, 6 are completely locked, and their movement and rotation are impossible. Therefore, even if an illegal wire is inserted through the gap in the front frame and the upper operating rod 7, the lower operating rod 8, and the latch members 5 and 6 are moved to cancel the illegal operation, it is completely impossible, and an incorrect answer is obtained with a very high probability. Locking can be prevented. The locking operation can be performed by a simple operation in which the user closes the front frame 21 with a key and simultaneously pushes in the cylinder lock 9 at the same time. If 9 is pulled, the cylinder lock 9 is pulled out and unlocked as it is, so that the unlocking operation can be performed very smoothly.

図２０は、他の実施形態を示している。この例では、シリンダ錠９の元部つまりフランジ９ａと基枠体１の取付板２の幅広部２ａとの間に、ばね部材（コイルばね）９ｃが、シリンダ錠９を基枠体１に押し込む方向に付勢した装着されている。このように、シリンダ錠９を基枠体１側に押し込む方向に付勢するばね部材９ｃを装着すれば、施錠時、前面枠２１を閉じて、ラッチ部材５，６を施錠位置に回動させれば、自動的にシリンダ錠９が基枠体１に押し込まれ、使用者はキーを持たずに前面枠２１を閉じるだけの簡単な操作で、施錠することができる。 FIG. 20 shows another embodiment. In this example, a spring member (coil spring) 9c pushes the cylinder lock 9 into the base frame 1 between the base portion of the cylinder lock 9, that is, the flange 9a and the wide portion 2a of the mounting plate 2 of the base frame 1. Mounted biased in the direction. Thus, if the spring member 9c that urges the cylinder lock 9 toward the base frame 1 is attached, the front frame 21 is closed and the latch members 5 and 6 are rotated to the locked position during locking. Then, the cylinder lock 9 is automatically pushed into the base frame body 1, and the user can lock it with a simple operation of simply closing the front frame 21 without holding the key.

なお、上記実施形態では、上部のラッチ部材５を下側に回動させ、下部のラッチ部材６を上側に回動させて施錠する構造としたが、上部のラッチ部材、下部のラッチ部材を共に同じ方向に回動させて施錠する構造とすることもでき、その場合は、上部と下部のラッチ部材を1本の作動杆で連結し、その作動杆と基枠体との間にコイルばねを装着して解錠方向に付勢し、施錠時にはシリンダ錠を押し込むことにより、その作動杆をロックする構造とすればよい。 In the above embodiment, the upper latch member 5 is pivoted downward and the lower latch member 6 is pivoted upward to lock the upper latch member. It can also be structured to lock by rotating in the same direction. In that case, the upper and lower latch members are connected with one operating rod, and a coil spring is connected between the operating rod and the base frame. A structure may be adopted in which the operating rod is attached and urged in the unlocking direction and the cylinder lock is pushed in to lock the operating rod.
