When fitted, a guard wall positioned so as to overlap with the support plate is extended to the front side of the receiving metal fitting .

また、請求項２の発明は、上記請求項１の施錠装置において、前記解錠位置保持機構が、前記施錠杆に揺動可能に枢支された揺動保持部材と、該揺動保持部材を係止側に付勢するばね部材とから構成され、シリンダ錠によってカム部材が回動し該施錠杆が解錠位置まで摺動したとき、該揺動保持部材の係止片が基枠体の一部に係止されて当該位置を保持することを特徴とする。 The invention according to claim 2 is the locking device according to claim 1, wherein the unlocking position holding mechanism includes a swing holding member pivotally supported by the lock rod, and the swing holding member. And a spring member biased toward the locking side. When the cam member is rotated by the cylinder lock and the locking rod is slid to the unlocking position, the locking piece of the swing holding member is The position is held by being partially locked.

さらに、請求項３の発明は、請求項１記載の施錠装置において、施錠完了時に前記施錠杆の動きをロックするロック部材が前記基枠体の支持板に取り付けられ、該ロック部材は解錠時、カム部材の回動に応じてロックを解除することを特徴とする。 Further, the invention of claim 3 is the locking device according to claim 1, wherein a lock member for locking the movement of the lock rod is attached to the support plate of the base frame body when the lock is completed, and the lock member is unlocked at the time of unlocking. , and cancels the lock in accordance with the rotation of the cam member.

上記請求項１の施錠装置によれば、施錠杆の上部と下部に鉤部が設けられる一方、上部と下部の鉤部の間に１つまたは複数の鉤部が設けられ、前扉を閉鎖した際、少なくとも３つの鉤部が受け金具の係止部に係止されるから、従来の２個の鉤部を有した施錠装置に比べ、閉鎖保持力がより増大し、バールなどによる前扉のこじ開けを防止することができる。   According to the locking device of the first aspect, the hooks are provided on the upper and lower parts of the locking hook, while one or more hooks are provided between the upper and lower hooks to close the front door. At this time, since at least three hooks are locked to the locking part of the receiving metal fitting, the closing holding force is further increased as compared with the conventional locking device having two hooks, and the front door such as a bar is used. It is possible to prevent opening.

また、解錠時に施錠杆を解錠位置に保持し、前扉の閉鎖時に解錠位置の保持を解除する解錠位置保持機構を設けることにより、前扉の閉鎖時、前扉をより軽く良好に閉じることができる。すなわち、従来のスライド式の施錠杆を有する施錠装置では、前扉を閉鎖する際、施錠杆の鉤部が受け金具の係止部に接触し、その反力を施錠杆の長手方向に受けて施錠杆が摺動し、ロックされるため、鉤部が３個或はそれ以上になると、鉤部と係止部間の摩擦抵抗が増大し、前扉を閉じる力が大きく必要となるところ、施錠杆の解錠位置保持機構を設け、解錠時に施錠杆を解錠位置に保持し、前扉の閉鎖時に解錠位置の保持を解除する構成とすれば、前扉の閉鎖時に鉤部と係止部間の摩擦抵抗が殆ど発生せず、鉤部の数に関わらず、前扉を軽く閉じることができる。   In addition, the front door is lighter and better when the front door is closed by providing an unlocking position holding mechanism that holds the locking bar in the unlocked position when unlocked and releases the unlocked position when the front door is closed. Can be closed. That is, in a conventional locking device having a sliding lock rod, when the front door is closed, the hook portion of the lock rod comes into contact with the locking portion of the receiving metal and the reaction force is received in the longitudinal direction of the lock rod. Since the locking rod slides and is locked, if there are three or more collars, the frictional resistance between the collar and the locking part increases, and a large force to close the front door is required. If a mechanism for holding the unlocking position of the locking rod is provided, the locking rod is held in the unlocking position when unlocking, and the unlocking position is released when the front door is closed, Friction resistance between the locking portions hardly occurs, and the front door can be lightly closed regardless of the number of flanges.

また、前扉の閉鎖時、受け金具のガード壁によって前扉とキャビネット間の縦の隙間が完全に閉鎖され、施錠装置の施錠杆などの内部機構がガード壁により外側に対しガードされる状態となる。また、前扉の閉鎖時、施錠装置の基枠体の支持板の縁部が受け金具の嵌入部に嵌入するから、キャビネットに固定された受け金具と前扉に固定された施錠装置とは強固に一体化された状態となる。特に、前扉の隙間にバール状の不正工具を差し込んでこじ開けようとしたとき、前扉に横方向の大きな荷重がかかり、前扉がキャビネットに対し横方向にずれて、前扉の隙間が開く場合があるところ、基枠体の支持板の縁部が受け金具の嵌入部に嵌入して両者が一体化することより、堅強な構造となり、横方向の荷重に対する曲げ強度と閉鎖保持力が増大し、こじ開けによる不正解錠を防止することができる。 In addition , when the front door is closed, the vertical gap between the front door and the cabinet is completely closed by the guard wall of the catch metal, and the internal mechanism such as the locking rod of the locking device is guarded against the outside by the guard wall. Become. Further, when the front door is closed, the edge of the support plate of the base frame body of the locking device is inserted into the receiving portion of the receiving bracket, so that the receiving bracket fixed to the cabinet and the locking device fixed to the front door are strong. It will be in the state integrated. In particular, when a bar-shaped unauthorized tool is inserted into the front door gap to pry it open, a large lateral load is applied to the front door, causing the front door to move laterally with respect to the cabinet, opening the front door gap. In some cases, the edge of the support plate of the base frame body is fitted into the fitting part of the receiving metal fitting, and both are integrated, resulting in a strong structure and increased bending strength and closing retention force against lateral loads. In addition, unauthorized unlocking by prying open can be prevented.

また、請求項３の発明によれば、施錠完了時にロック部材が施錠杆の動きをロックするから、仮に不正な針金などを内側に差し込み、施錠杆を動かして不正解錠を行なおうとしても、施錠状態の施錠杆はロック部材によりロックされているから、不正解錠を防止することができる。 According to the invention of claim 3 , since the locking member locks the movement of the locking rod when the locking is completed, even if an unauthorized wire or the like is inserted inside and the locking rod is moved, the unlocking may be performed. Since the locked locking rod is locked by the lock member, unauthorized unlocking can be prevented.

Further, a coil spring 9 c is stretched between the spring hooking portion 15 b provided at the tip of the swing holding member 15 and the locking rod 10. The swing holding member 15 can swing back and forth around the pivot pin 15c, and is biased by the coil spring 9c to swing the locking piece 15a toward the mounting plate 2. . That is, as shown in FIGS. 2 and 5, when the stopper portion 2a is formed at the corresponding position of the mounting plate 2 of the base frame 1, and the locking rod 10 slides to the unlocked position, the biasing force of the coil spring 9c As a result, the swing holding member 15 swings, and the locking piece 15a is locked to the stopper portion 2a.

一方、取付板２の一部を形成する補助取付板４に穿設された挿入孔には、フランジ部付きのシリンダ錠７が前面側に突き出すように挿入され、そのフランジ部をねじ又はかしめで補助取付板４に固定して装着される。シリンダ錠７の錠軸には第一係合部８ａと第二係合部８ｂを持つカム部材８が固定される。図３の反時計方向にカム部材８を回動させた場合、カム部材８の第一係合部８ａは施錠杆１０の係合部１０ａに係合し、施錠杆１０を下方に摺動させ、４個の鉤部１０ａ〜１０ｄを下側に移動させて解錠する。   On the other hand, a cylinder lock 7 with a flange portion is inserted into an insertion hole formed in the auxiliary mounting plate 4 forming a part of the mounting plate 2 so as to protrude to the front side, and the flange portion is screwed or caulked. The auxiliary mounting plate 4 is fixedly mounted. A cam member 8 having a first engagement portion 8 a and a second engagement portion 8 b is fixed to the lock shaft of the cylinder lock 7. When the cam member 8 is rotated counterclockwise in FIG. 3, the first engaging portion 8a of the cam member 8 is engaged with the engaging portion 10a of the locking rod 10, and the locking rod 10 is slid downward. The four hooks 10a to 10d are moved downward to unlock them.

図５に示すように、支持板３におけるカム部材８の近傍位置には、施錠杆１０を施錠位置でロックするためのロック部材１６が、枢支ピン１６ａにより支持板３の内側面に揺動可能に枢支される。このように支持板３に枢支されるロック部材１６には、その先端にばね掛け部１６ｃが正面視で左側に突出して形成され、その係止部となるばね掛け部１６ｃと施錠杆１０との間にコイルばね９ｂが掛け渡される。そして、この係止部兼用のばね掛け部１６ｃは、コイルばね９ｂの付勢力により、施錠杆１０の対応位置に設けた係止部１０ｂに係止される側に付勢されている。   As shown in FIG. 5, in the vicinity of the cam member 8 on the support plate 3, a lock member 16 for locking the lock rod 10 in the lock position swings on the inner surface of the support plate 3 by a pivot pin 16a. It is pivoted as possible. In this way, the lock member 16 pivotally supported by the support plate 3 is formed with a spring hooking portion 16c projecting to the left in front view, and the spring hooking portion 16c serving as the locking portion and the locking rod 10 The coil spring 9b is stretched between. And this latching part 16c used as a latching part is urged | biased by the side latched by the latching | locking part 10b provided in the corresponding position of the locking rod 10 with the urging | biasing force of the coil spring 9b.

したがって、施錠状態において、施錠杆１０はロック部材１６のばね掛け部１６ｃが係止部１０ｂに進入して係止され、その移動をロックされた状態となる。さらに、ロック部材１６の末端には、ロック解除用係合部１６ｂがカム部材８側に突出して形成されている。このロック解除用係合部１６ｂは、シリンダ錠７の解錠操作時にカム部材８が解錠方向に回動したとき、その最初の段階で、第一係合部８ａにより押下げられ、ロック部材１６は非ロック位置に、つまり図１０のようにばね掛け部１６ｃを係止部１０ｂから退出させる。これにより、施錠杆１０のロックが解除されて、解錠方向に移動可能となり、その状態で、施錠杆１０はカム部材８の回動により下降して解錠が行なわれる。   Accordingly, in the locked state, the locking rod 10 is locked by the spring hooking portion 16c of the lock member 16 entering the locking portion 10b and locked. Further, an unlocking engagement portion 16 b is formed at the end of the lock member 16 so as to protrude toward the cam member 8. When the cam member 8 rotates in the unlocking direction during the unlocking operation of the cylinder lock 7, the unlocking engaging portion 16 b is pushed down by the first engaging portion 8 a at the first stage, and the locking member Reference numeral 16 denotes an unlocked position, that is, the spring hooking portion 16c is retracted from the locking portion 10b as shown in FIG. Thereby, the lock of the lock rod 10 is released, and the lock rod 10 can move in the unlocking direction. In this state, the lock rod 10 is lowered by the rotation of the cam member 8 and unlocked.

さらに、図５のように、スイッチ作動杆１７が支持板３と施錠杆１０の間に摺動可能に配設される。スイッチ作動杆１７には、その上部に係合部１７ａがカム部材８の第二係合部８ｂと係合可能に設けられ、カム部材８が図３の時計方向に回動したとき、その第二係合部８ｂが係合部１７ａに係合し、スイッチ作動杆１７は上方に摺動する。スイッチ作動杆１７と補助取付板４との間に、コイルばね９ｄが装着され、スイッチ作動杆１７はコイルばね９ｄにより下方に付勢されている。スイッチ作動杆１７の下部には、正面視で左側に突出して作動片１７ｂが設けられ、補助取付板４の下部に非接触スイッチ１９が取り付けられ、スイッチ作動杆１７が上方に摺動したとき、作動片１７ｂが非接触スイッチ１９に作用して、スイッチをオンオフ動作させる構造である。   Further, as shown in FIG. 5, the switch operating rod 17 is slidably disposed between the support plate 3 and the locking rod 10. The switch operating rod 17 is provided with an engaging portion 17a at an upper portion thereof so as to be engageable with the second engaging portion 8b of the cam member 8, and when the cam member 8 is rotated clockwise in FIG. The two engaging portions 8b engage with the engaging portions 17a, and the switch operating rod 17 slides upward. A coil spring 9d is mounted between the switch operating rod 17 and the auxiliary mounting plate 4, and the switch operating rod 17 is urged downward by the coil spring 9d. An operating piece 17b is provided at the lower part of the switch operating rod 17 so as to protrude to the left in front view. A non-contact switch 19 is attached to the lower part of the auxiliary mounting plate 4, and when the switch operating rod 17 slides upward, The actuating piece 17b acts on the non-contact switch 19 to turn the switch on and off.

このように構成された施錠装置は、図９に示すように、スロットマシンの前扉３１の内側に、シリンダ錠７の先端を前面に露出させ、第１鉤部１１〜第４鉤部１４をキャビネット３０側に向けた状態で、取付板２と固定ねじを用いて縦に取付けられる。一方、キャビネット３０の前開口部の正面視で右側の側壁の内側には、受け金具２０が縦に固定される。   As shown in FIG. 9, the locking device configured as described above exposes the front end of the cylinder lock 7 on the front side of the front door 31 of the slot machine, and the first hook part 11 to the fourth hook part 14. In the state facing the cabinet 30 side, it is vertically mounted using the mounting plate 2 and fixing screws. On the other hand, the receiving metal fitting 20 is fixed vertically inside the right side wall in front view of the front opening of the cabinet 30.

受け金具２０は、図７、図８に示すように、その本体が縦長の帯状金属板から形成され、特にその長さは、キャビネット３０の前開口部の上端から下端まで全体にわたって当接するように長尺に形成され、また、受け金具２０の前側には、図８のように、ガード壁２５が本体と同じ長さの帯状金属板を本体の前部に張り合わせ、且つ幅を拡幅するように固定されている。このように、受け金具２０は２枚の金属板を張り合わせることにより、非常に剛性を高くして幅広に形成され、キャビネット３０の縦辺部を補強すると共に、前扉３１との間に生じやすい隙間を塞ぐ機能を有している。   As shown in FIGS. 7 and 8, the metal fitting 20 is formed of a vertically long band-shaped metal plate, and particularly its length is in contact with the entire upper end to the lower end of the front opening of the cabinet 30. As shown in FIG. 8, the guard wall 25 is attached to the front part of the main body, and the width is widened on the front side of the metal fitting 20 as shown in FIG. It is fixed. In this manner, the receiving metal 20 is formed to be very wide with a very high rigidity by bonding two metal plates together, reinforcing the vertical side portion of the cabinet 30, and occurring between the front door 31. It has a function to close easy gaps.

さらに、受け金具２０には、正面視で左側面に、４個の係止部２１，２２，２３，２４が上記施錠杆１０の第１鉤部１１〜第４鉤部１４に対応した位置に、内側に突出して設けられる。また、受け金具２０には、上記基枠体１の支持板３の背面側縁部を嵌入させるために、複数のスリット状の嵌入部２６が、係止部２１〜２４の間と係止部２１の上方、及び係止部２４の下方に、合計６箇所に分かれて形成されている。   Further, on the receiving metal 20, the four locking portions 21, 22, 23, and 24 are located on the left side when viewed from the front, at positions corresponding to the first flange portion 11 to the fourth flange portion 14 of the locking rod 10. , Projecting inward. In addition, a plurality of slit-like fitting portions 26 are provided between the locking portions 21 to 24 and the locking portions in order to insert the back side edge portion of the support plate 3 of the base frame body 1 into the receiving bracket 20. A total of six locations are formed above 21 and below the locking portion 24.

これらの嵌入部２６は、金属板からなる受け金具本体の一部を階段状に折り曲げ、支持板３の縁部を嵌入可能な凹部を、ガード壁２５との間に形成している。ガード壁２５は、嵌入部２６より前方に突出し、キャビネット３０の前縁部と前扉３１との間に生じやすい隙間を、ガード壁２５により閉鎖するものである。さらに、受け金具２０の係止部２２の上方には、上述の揺動保持部材１５の先端部が前扉３１を閉じた際、当接する当接部２８が設けられ、キャビネット３０に対し前扉３１を閉じたとき、揺動保持部材１５の先端がこの当接部２８に当り、それにより、揺動保持部材１５が揺動して施錠杆１０の解錠位置保持を解除する。また、受け金具２０の下部には、上記支持板３の下部に設けた支持ローラ１８が閉鎖時に乗り上げる滑り板２７が設けられている。このような受け金具２０は、図１０のように、ガード壁２６がキャビネット３０の右側の側壁の前開口縁部を覆うように取り付けられている。   These fitting portions 26 are formed between the guard wall 25 and concave portions in which a part of the metal fitting body made of a metal plate is bent in a stepped manner and the edges of the support plate 3 can be fitted. The guard wall 25 protrudes forward from the fitting portion 26 and closes a gap that is likely to be generated between the front edge portion of the cabinet 30 and the front door 31 by the guard wall 25. Further, an abutting portion 28 that abuts when the front end portion of the swing holding member 15 closes the front door 31 is provided above the locking portion 22 of the metal fitting 20. When 31 is closed, the tip of the swing holding member 15 hits the abutting portion 28, thereby swinging the swing holding member 15 and releasing the unlocked position of the lock rod 10. In addition, a sliding plate 27 is provided at the lower part of the metal fitting 20 so that the supporting roller 18 provided at the lower part of the supporting plate 3 rides on when it is closed. As shown in FIG. 10, such a metal fitting 20 is attached so that the guard wall 26 covers the front opening edge of the right side wall of the cabinet 30.

前扉３１が閉じられ、施錠された状態においては、図９のように、施錠杆１０の第１鉤部１１〜第４鉤部１４が各々、受け金具２０の係止部２１，２２，２３，２４に係止され、さらに、基枠体１の支持板３の縁部が、受け金具２０の全体にわたり複数形成された嵌入部２６に嵌め込まれて、施錠状態となっている。   In the state where the front door 31 is closed and locked, as shown in FIG. 9, the first flange portion 11 to the fourth flange portion 14 of the locking rod 10 are respectively the locking portions 21, 22, 23 of the metal fitting 20. , 24, and the edge of the support plate 3 of the base frame 1 is fitted into a plurality of insertion portions 26 formed over the entire receiving metal fitting 20 to be locked.

したがって、４個の第１鉤部１１〜第４鉤部１４と受け金具２０の係止部２１，２２，２３，２４の係止により、充分な閉鎖保持力で前扉３１を閉鎖すると共に、嵌入部２６への支持板３の嵌入により、前扉３１側の施錠装置が強固に受け金具２０と一体となってロックされる。このため、バールなどの不正工具により前扉３１が横方向に大荷重を受けたような場合、施錠装置の基枠体１と受け金具２０によりその荷重を受けて、前扉３１の変形や隙間の拡大を阻止し、不正解錠を効果的に防止することができる。   Accordingly, the front door 31 is closed with a sufficient closing holding force by the engagement of the four first flange portions 11 to the fourth flange portion 14 and the locking portions 21, 22, 23, 24 of the receiving metal fitting 20, By inserting the support plate 3 into the insertion portion 26, the locking device on the front door 31 side is firmly and integrally locked with the receiving metal fitting 20. For this reason, when the front door 31 receives a large load in the lateral direction by an unauthorized tool such as a bar, the load is received by the base frame body 1 and the metal fitting 20 of the locking device, and the deformation or gap of the front door 31 is detected. Can be prevented and unauthorized unlocking can be effectively prevented.

また、施錠状態においては、ロック部材１６がそのばね掛け部の係止部１６ａを施錠杆１０の係止部１０ｂに係止して施錠杆１０の動きをロックするから、仮に不正な針金などを内側に差し込み、施錠杆を動かして不正解錠を行なおうとしても、施錠状態の施錠杆１０はロック部材１６によりロックされ、不正解錠を防止することができる。   In the locked state, the lock member 16 locks the locking portion 16b of the spring hook portion to the locking portion 10b of the locking rod 10 to lock the movement of the locking rod 10. Even if it is inserted inside and the locking rod is moved to perform unauthorized unlocking, the locked locking rod 10 in the locked state is locked by the lock member 16, and unauthorized unlocking can be prevented.

前扉３１をキーにより解錠する場合は、キーでシリンダ錠７の錠軸を回し、カム部材８を図３反時計方向に回転させる。このとき、カム部材８の第一係合部８ａが、先ずロック部材１６の係合部１６ｂに係合して、ロック部材１６を図１０の如く時計方向に回動させ、ロック部材１６の係止部兼用のばね掛け部１６ｃと施錠杆１０の係止部１０ｂとの係合を外してロックを解除する。更に、第１係合部８ａが施錠杆１０の係合部１０ａと係合してこれを下方へ摺動させ、図１０のように、４個の鉤部１１〜１４を下方に移動させる。   When unlocking the front door 31 with a key, the lock shaft of the cylinder lock 7 is rotated with the key, and the cam member 8 is rotated counterclockwise in FIG. At this time, the first engagement portion 8a of the cam member 8 is first engaged with the engagement portion 16b of the lock member 16, and the lock member 16 is rotated clockwise as shown in FIG. The lock is released by releasing the engagement between the spring hooking portion 16c serving also as a stopper and the locking portion 10b of the locking rod 10. Further, the first engaging portion 8a engages with the engaging portion 10a of the locking rod 10 and slides it downward, and moves the four flange portions 11 to 14 downward as shown in FIG.

この鉤部１１〜１４の移動によって、キャビネット３０側の受け金具２０の各係止部２１〜２４との係合が外れ、前扉３１は開放される。そして、上記のように解錠操作してキャビネット３０から前扉３１が開放されると、当接部２８による揺動保持部材１５の先端部の押さえが外れるため、揺動保持部材１５がコイルばね９ｃの付勢力により図１０の時計方向に回動する。このとき、揺動保持部材１５の係止片１５ａが取付板２の係止部２ａに係止され、図１０のように、施錠杆１０が解錠位置に保持される。また、ロック部材１６は、キーを解錠方向に回したとき、図１０のように時計方向に回動した状態となるが、キーを元の位置に戻せば、ロック部材１６はコイルばね９ｂの力により、図１１のような状態に戻り、揺動保持部材１５及び施錠杆１０は解除位置に保持される。   Due to the movement of the flange portions 11 to 14, the engagement with the respective locking portions 21 to 24 of the bracket 20 on the cabinet 30 side is released, and the front door 31 is opened. When the front door 31 is opened from the cabinet 30 by the unlocking operation as described above, the pressing of the tip end portion of the swing holding member 15 by the contact portion 28 is released, so that the swing holding member 15 is a coil spring. It is rotated in the clockwise direction of FIG. 10 by the urging force of 9c. At this time, the locking piece 15a of the swing holding member 15 is locked to the locking portion 2a of the mounting plate 2, and the locking rod 10 is held in the unlocked position as shown in FIG. When the key is rotated in the unlocking direction, the lock member 16 is rotated in the clockwise direction as shown in FIG. 10, but when the key is returned to the original position, the lock member 16 is rotated by the coil spring 9b. Due to the force, the state returns to the state shown in FIG.

そして次に、開放された前扉３１を施錠する場合、前扉３１をキャビネット３０に対し軽く押して閉じる。このとき、先ず、図１１に示す揺動保持部材１５の先端がキャビネット３０側の受け金具２０の当接部２８に当接し、図の反時計方向に揺動保持部材１５が押されて回動するため、その係止片１５ａと取付板２の係止部２ａとの係合が外れ、同時に前扉３１が閉鎖位置に達する。このとき、施錠杆１０はその係止が外れるため、コイルばね９ａの付勢力によって上方（施錠方向）に移動し、施錠杆１０の第１鉤部〜第４鉤部１１〜１４は、図９、図１２のように、受け金具２０の係止部２１〜２４に各々係止され、施錠状態となる。   Then, when locking the opened front door 31, the front door 31 is lightly pressed against the cabinet 30 and closed. At this time, first, the tip of the swing holding member 15 shown in FIG. 11 comes into contact with the abutting portion 28 of the receiving bracket 20 on the cabinet 30 side, and the swing holding member 15 is pushed and rotated counterclockwise in the drawing. Therefore, the engagement between the locking piece 15a and the locking portion 2a of the mounting plate 2 is released, and at the same time, the front door 31 reaches the closed position. At this time, since the locking rod 10 is unlocked, the locking rod 10 moves upward (locking direction) by the biasing force of the coil spring 9a, and the first to fourth hook portions 11 to 14 of the locking rod 10 are shown in FIG. As shown in FIG. 12, they are respectively locked by the locking portions 21 to 24 of the metal fitting 20 and are locked.

このように、本発明の施錠装置によれば、施錠杆１０に設けた４つの鉤部１１〜１４が受け金具２０の係止部２１〜２４に係止されるから、従来の２個の鉤部を有した施錠装置に比べ、閉鎖保持力がより増大し、バールなどによる前扉のこじ開けを防止することができる。また、施錠杆１０の解錠位置保持機構として揺動保持部材を設け、解錠時に施錠杆１０を解錠位置に保持し、前扉の閉鎖時に解錠位置の保持を解除するから、前扉３１の閉鎖時に鉤部１１〜１４と係止部２１〜２４間の摩擦抵抗が殆ど発生せず、鉤部の数に関わらず、前扉３１を軽く閉じることができる。   Thus, according to the locking device of the present invention, since the four hook parts 11 to 14 provided on the lock hook 10 are locked to the locking parts 21 to 24 of the receiving metal fitting 20, the two conventional hooks are provided. Compared to a locking device having a portion, the closing holding force is further increased, and the front door can be prevented from being opened by a bar or the like. Further, a rocking holding member is provided as an unlocking position holding mechanism of the locking rod 10, and the locking rod 10 is held in the unlocking position when unlocking, and the unlocking position is released when the front door is closed. Friction resistance between the flanges 11 to 14 and the locking portions 21 to 24 hardly occurs when 31 is closed, and the front door 31 can be lightly closed regardless of the number of flanges.

さらに、受け金具２０にはガード壁２５が固定されて補強され、施錠時、基枠体１の支持板３の縁部が受け金具１０の嵌入部２６に嵌入し、施錠装置と受け金具２０が一体に組み付いて施錠されるから、その構造は非常に堅強となって、バールなどを使用したこじ開けにより、前扉３１に横方向の荷重がかけられても、前扉の横方向のズレは阻止され、こじ開けによる不正解錠を防止することができる。   Further, the guard wall 25 is fixed and reinforced to the metal fitting 20, and at the time of locking, the edge of the support plate 3 of the base frame body 1 is fitted into the fitting portion 26 of the metal fitting 10, and the locking device and the metal fitting 20 are connected. Since it is assembled and locked together, its structure is very strong, and even if a lateral load is applied to the front door 31 by prying using a bar, the lateral displacement of the front door It is blocked and unauthorized unlocking by prying up can be prevented.

なお、上記実施形態では、スロットマシンの施錠装置について説明したが、パチンコ機などの他のゲーム機の施錠装置に適用することもできる。また、上記では施錠杆に４個の鉤部を設けたが、３個または５個の鉤部を設けて構成することもできる。   In the embodiment described above, the locking device of the slot machine has been described, but it can also be applied to a locking device of another game machine such as a pachinko machine. In the above description, the locking hook is provided with four hooks, but the lock hook may be provided with three or five hooks.
