さらに、請求項3の施錠装置は、筐体側の内側に固定された受け部内のラックに、前扉側の内側に固定された装置本体の歯車部を噛合させて前扉を施錠する遊技機用施錠装置であって、受け部には歯車部を進入させる進入凹部が形成されると共に、進入凹部の内面にラックが歯車部の進入方向に向けて形成され、歯車部には、係合歯車が回転可能に軸支されると共に、係合歯車の軸と同軸上にラチェット歯車が軸支され、ラチェット歯車のラチェット爪を非噛合側に揺動させるための解錠部材が摺動可能に配設され、解錠部材をシリンダ錠の錠軸に固定したカム板に連係させたことを特徴とする。   Furthermore, the locking device according to claim 3 is for a gaming machine that locks the front door by meshing the gear portion of the device main body fixed on the inner side on the front door side with the rack in the receiving portion fixed on the inner side on the housing side. In the locking device, the receiving portion is formed with an entering recess for allowing the gear portion to enter, and a rack is formed on the inner surface of the entering recess toward the entering direction of the gear portion. The ratchet gear is pivotally supported coaxially with the shaft of the engaging gear, and an unlocking member for swinging the ratchet pawl of the ratchet gear to the non-meshing side is slidably disposed. The unlocking member is linked to a cam plate fixed to the lock shaft of the cylinder lock.

ここで、上記請求項3の施錠装置においては、請求項4のように、受け部は筐体の上部と下部に取り付けられると共に、歯車部は装置本体の基枠の上部と下部に取り付けられ、歯車部の係合歯車はラチェット歯車より小径に形成され、装置本体の基枠にシリンダ錠が固定され、基枠内にカム板が錠軸に固定されて配設され、カム板が係合する解錠部材を施錠方向に付勢するばね部材が設けられた構成とすることができる。   Here, in the locking device according to claim 3, as in claim 4, the receiving portion is attached to the upper and lower portions of the housing, and the gear portion is attached to the upper and lower portions of the base frame of the device main body. The engaging gear of the gear portion is formed to have a smaller diameter than the ratchet gear, the cylinder lock is fixed to the base frame of the apparatus main body, the cam plate is fixed to the lock shaft in the base frame, and the cam plate is engaged. It can be set as the structure provided with the spring member which urges | biases an unlocking member to a locking direction.

この遊技機用施錠装置は、遊技機の前扉を筐体に対し閉じると、前扉側の歯車部の係合歯車が筐体側の受け部の進入凹部内に進入する。このとき、装置本体側の係合歯車が、進入凹部内のラックに噛合して内部に進入する。ラックには多数の鋸歯が進入方向に向かって配置され、係合歯車にはラチェット歯車が噛合し或いは同軸上に配設されるため、係合歯車は後戻りすることができない。このため、前扉を筐体に対して閉じるに応じて、歯車部が受け部の奥まで進入し、その進入位置を保持するように係合歯車がラックに噛合すると共に、ラチェット歯車が係合歯車の開放側への回動をロックし、前扉は施錠状態となり、前扉をがたつきなく施錠することができる。   In this gaming machine locking device, when the front door of the gaming machine is closed with respect to the housing, the engaging gear of the gear portion on the front door side enters the entry recess of the receiving portion on the housing side. At this time, the engagement gear on the apparatus main body side meshes with the rack in the entry recess and enters the inside. A large number of saw teeth are arranged in the rack in the approach direction, and a ratchet gear is engaged with the engaging gear or is coaxially arranged, so that the engaging gear cannot be returned. For this reason, as the front door is closed with respect to the housing, the gear portion enters the depth of the receiving portion, the engagement gear meshes with the rack so as to maintain the entry position, and the ratchet gear engages. The rotation of the gear toward the opening side is locked, the front door is locked, and the front door can be locked without rattling.

さらに、歯車部の係合歯車をラチェット歯車より大径に或いは小径に形成してその歯数を変え、ギヤ比を1以外に変えることにより、前扉を筐体側に閉じる閉鎖力に応じて、係合歯車が噛合するラックのピッチより小さいピッチで、歯車部を受け部に対しロックすることができる。   Furthermore, according to the closing force that closes the front door to the housing side by changing the gear ratio to other than 1 by forming the engagement gear of the gear part larger or smaller than the ratchet gear and changing the number of teeth thereof, The gear portion can be locked to the receiving portion at a pitch smaller than the pitch of the rack with which the engaging gear meshes.

つまり、ラチェット歯車が係合歯車の歯数より細かい角度でロックすることができるため、係合歯車のピッチつまりラックの歯のピッチより細かいピッチで係合歯車のロックが可能となり、歯車部を有する装置本体の僅かな移動に応じて、ラックに噛合する係合歯車をロックすることができる。   In other words, since the ratchet gear can be locked at an angle finer than the number of teeth of the engagement gear, the engagement gear can be locked at a pitch finer than the pitch of the engagement gear, that is, the rack teeth, and has a gear portion. The engagement gear meshing with the rack can be locked according to the slight movement of the apparatus main body.

したがって、前扉を筐体側に押して閉じたとき、閉じる動作に応じてラックのピッチより細かいピッチでラチェット歯車と係合歯車がロックされるため、前扉は筐体に対しがたつきなく、堅固に施錠することができる。またこれによって、係合歯車とラックの歯は、ある程度大きく強固に製作することができ、強度の高い施錠装置とすることができる。   Therefore, when the front door is pushed and closed to the housing side, the ratchet gear and the engaging gear are locked at a pitch finer than the rack pitch according to the closing operation. Can be locked. In addition, the engaging gear and the rack teeth can be manufactured to a certain extent large and firmly, and a locking device with high strength can be obtained.

一方、前扉を解錠する場合は、キーによってシリンダ錠を回し、カム部材を所定方向に回転させると、カム部材の回動によって、それに連係された解錠部材が摺動してラチェット歯車のラチェット爪を外す方向に回動させる。これにより、ラチェット歯車の爪が外れて回動自在の状態となり、係合歯車が回動可能な状態となって前扉が解錠され、歯車部が回動しながら後退して受け部の進入凹部内から退出し、前扉は開放される。   On the other hand, when unlocking the front door, the cylinder lock is rotated by the key and the cam member is rotated in a predetermined direction. As the cam member rotates, the unlocking member linked to it slides and the ratchet gear rotates. Rotate in the direction to remove the ratchet pawl. As a result, the pawls of the ratchet gear come off and become rotatable, the engaging gear becomes rotatable, the front door is unlocked, and the gear part moves backward while rotating to enter the receiving part. Retreating from the inside of the recess, the front door is opened.

以下、本発明の実施例を図面に基づいて説明する。図1は前扉に取り付けられる装置本体1の右側面図を示し、図2はその背面図を示している。この施錠装置は、概略的には、筐体側の内側に固定された受け部21,22に、前扉側の内側に固定された装置本体1の歯車部3,4を進入させながらロックして前扉を施錠するように構成される。   Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a right side view of the apparatus main body 1 attached to the front door, and FIG. 2 shows a rear view thereof. In general, the locking device locks the receiving portions 21 and 22 fixed on the inner side of the casing while allowing the gear portions 3 and 4 of the device main body 1 fixed on the inner side of the front door to enter. Configured to lock the front door.

装置本体1は、縦長の基枠2を有し、基枠2は、長尺の取付板2aと支持板2bを直角に曲折してL型アングル状に形成される。その支持板2bの上部と下部に突出部が背面側に突出して形成され、その部分に歯車部3,4の係合歯車5,6が、水平軸により回転可能につまり垂直状態で回転可能に軸支されている。   The apparatus main body 1 has a vertically long base frame 2, and the base frame 2 is formed in an L-shaped angle by bending a long mounting plate 2a and a support plate 2b at a right angle. Projections are formed on the upper and lower portions of the support plate 2b so as to project to the back side, and the engagement gears 5 and 6 of the gear portions 3 and 4 can be rotated by the horizontal shaft, that is, in a vertical state. It is pivotally supported.

さらに、上部と下部の歯車部3,4には、各々、ラチェット歯車7,8が、上記各係合歯車5,6に噛合して、支持板2bの内側に水平軸により回転可能に軸支される。ラチェット歯車7,8は係合歯車5,6より小径に、係合歯車5,6はラチェット歯車7,8より大径に形成されている。つまり、係合歯車5,6とラチェット歯車7,8のギヤ比を例えば2:1に形成することにより、係合歯車5,6が噛合する後述のラック25,26の1ピッチの1/2のピッチで施錠ロックがかかるようにしている。   Further, ratchet gears 7 and 8 are respectively engaged with the engaging gears 5 and 6 on the upper and lower gear portions 3 and 4, and are supported on the inner side of the support plate 2b so as to be rotatable by a horizontal shaft. Is done. The ratchet gears 7 and 8 are formed to have a smaller diameter than the engagement gears 5 and 6, and the engagement gears 5 and 6 are formed to have a larger diameter than the ratchet gears 7 and 8. That is, by forming the gear ratio between the engagement gears 5 and 6 and the ratchet gears 7 and 8 to be 2: 1, for example, 1/2 of one pitch of racks 25 and 26 (described later) with which the engagement gears 5 and 6 mesh. The lock is locked at a pitch of.

さらに、上部と下部のラチェット歯車7,8には、各々その上方に、ラチェット爪9,10が軸9a,軸10aにより揺動可能に軸支され、上部と下部のラチェット爪9,10は各ラチェット歯車7,8に係合している。これにより、各ラチェット歯車7,8は、通常時、図1の時計方向には、ラチェット爪9,10の係止作用により回転を阻止され、反時計方向にのみ回転可能である。したがって、各ラチェット歯車7,8に噛合する上部と下部の係合歯車5,6は、通常時、図1の時計方向にのみ回転可能である。   Further, on the upper and lower ratchet gears 7 and 8, ratchet claws 9 and 10 are pivotally supported on the upper and lower ratchet gears 9 and 8 by shafts 9a and 10a, respectively. The ratchet gears 7 and 8 are engaged. Thus, the ratchet gears 7 and 8 are normally prevented from rotating in the clockwise direction of FIG. 1 by the latching action of the ratchet claws 9 and 10 and can be rotated only in the counterclockwise direction. Accordingly, the upper and lower engaging gears 5 and 6 meshing with the ratchet gears 7 and 8 can normally rotate only in the clockwise direction of FIG.

さらに、基枠2の支持板2bの外側に、支持板2bの長手方向にそって長尺の解錠部材11が摺動可能に配設され、その解錠部材11の上端と下端には、連結ピン9b、10bが軸支されている。その連結ピン9b、10bは、支持板2bに形成された長孔を通して外側から内側に挿通され、支持板2bの内側において、上部と下部の各ラチェット爪9,10の端部に連結されている。   Furthermore, on the outside of the support plate 2b of the base frame 2, a long unlocking member 11 is slidably disposed along the longitudinal direction of the support plate 2b. The connecting pins 9b and 10b are pivotally supported.

At this time, in the gear portions 3 and 4, since the ratchet gears 7 and 8 are meshed with the engagement gears 5 and 6, the ratchet gears 7 and 8 are driven to rotate, and the ratchet gears 7 and 8 are driven in a rotation direction. It rotates only (counterclockwise in FIG. 5) and does not rotate in the reverse direction due to the action of the ratchet claws 9a, 10a. For this reason, when the engagement gears 5 and 6 advance on the racks 25 and 26 while rotating only in the forward direction (right direction in FIG. 5), and the front door 31 is tightly closed by the housing 30, the closed state is established. Is locked.

また、係合歯車5,6がラック25,26上を噛合して前進するとき、後退方向への動きはラチェット歯車7,8により阻止されるが、係合歯車5,6とラチェット歯車7,8のギヤ比は、例えば2:1のように、係合歯車5,6の歯数がより多く設定されている。このため、係合歯車5,6がラック25,26上を噛合して進むとき、ラチェット歯車7,8の回転は、この場合、係合歯車5,6の例えば2倍となるから、係合歯車5,6がラック25,26上を移動するピッチは、ラック25,26の歯のピッチの1/2となって、より細かくなる。   Further, when the engagement gears 5 and 6 move forward while meshing on the racks 25 and 26, the backward movement is prevented by the ratchet gears 7 and 8, but the engagement gears 5 and 6 and the ratchet gears 7 and 8 are prevented. The gear ratio of 8 is set such that the number of teeth of the engagement gears 5 and 6 is larger, for example, 2: 1. For this reason, when the engagement gears 5 and 6 are engaged with each other on the racks 25 and 26, the rotation of the ratchet gears 7 and 8 is, in this case, twice that of the engagement gears 5 and 6, for example. The pitch at which the gears 5 and 6 move on the racks 25 and 26 becomes 1/2 of the pitch of the teeth of the racks 25 and 26 and becomes finer.

したがって、例えばラック25,26のピッチが1mmと比較的大きいピッチであっても、係合歯車5,6に移動ピッチは0.5mmという細かいピッチでロックすることができる。このため、ラック25,26、及び係合歯車5,6の歯は、比較的大きくして形成して強度を上げながら、閉鎖ピッチは細かくすることができる。   Therefore, for example, even if the racks 25 and 26 have a relatively large pitch of 1 mm, the engagement gears 5 and 6 can be locked at a fine pitch of 0.5 mm. Therefore, the racks 25 and 26 and the teeth of the engagement gears 5 and 6 can be formed to be relatively large to increase the strength, and the closing pitch can be made fine.

このように、係合歯車5,6がラック25,26上を噛合して前進しながら、前扉31が筐体30に対し閉じられるが、装置本体1の係合歯車5,6が、ラック25,26の鋸歯の例えば半ピッチという細かい押し込み量で、装置本体1が受け部21,22に対し徐々にロックされていくため、最終的に前扉31を閉じた状態では、扉と筐体の間に殆ど隙間が生じず、前扉31はがたつきのない状態で筐体30に対し堅固にロックされる。   As described above, while the engagement gears 5 and 6 mesh with and move forward on the racks 25 and 26, the front door 31 is closed with respect to the housing 30. Since the apparatus body 1 is gradually locked with respect to the receiving portions 21 and 22 with a small push amount of, for example, a half pitch of the saw blades 25 and 26, the door and the housing are finally closed when the front door 31 is closed. There is almost no gap between the front door 31 and the front door 31 is firmly locked to the housing 30 in a state where there is no backlash.

前扉31を解錠する場合は、図6に示すように、キー17をシリンダ錠13に差し込みその錠軸13aを回し、カム板12を図2の時計方向に回転させると、カム板12の回転により、カム板12の係合部12aが同方向に回動して、支持板2bの開口部2cを通して、解錠部材11の係合部11aに係合し、それを下方に摺動させる。このとき、解錠部材11が下降すると、その上端と下端に連結されたラチェット爪9,10が図6の時計方向に回動し、ラチェット爪9,10とラチェット歯車7,8の係合が外れる。   When unlocking the front door 31, as shown in FIG. 6, when the key 17 is inserted into the cylinder lock 13 and the lock shaft 13a is rotated to rotate the cam plate 12 in the clockwise direction in FIG. By the rotation, the engaging portion 12a of the cam plate 12 rotates in the same direction, engages with the engaging portion 11a of the unlocking member 11 through the opening 2c of the support plate 2b, and slides it downward. . At this time, when the unlocking member 11 is lowered, the ratchet claws 9 and 10 connected to the upper and lower ends of the unlocking member 11 rotate in the clockwise direction in FIG. 6, and the ratchet claws 9 and 10 and the ratchet gears 7 and 8 are engaged. Come off.

これにより、ラチェット歯車7,8がフリーな状態となり、上下の歯車部3,4の係合歯車5,6のロックが解除され、図示しない開方向への付勢手段あるいは開操作により、係合歯車5,6が受け部21,22のラック25,26上を回転しながら、進入凹部23,24内から退出し、前扉31は開放される。   As a result, the ratchet gears 7 and 8 become free, the engagement gears 5 and 6 of the upper and lower gear portions 3 and 4 are unlocked, and are engaged by an urging means or an opening operation in an unillustrated opening direction. While the gears 5 and 6 rotate on the racks 25 and 26 of the receiving portions 21 and 22, the gears 5 and 6 retreat from the entry recesses 23 and 24, and the front door 31 is opened.

このように、本施錠装置では、前扉31を筐体30に対し閉じるに応じて、上下の歯車部3,4の係合歯車5,6が受け部21,22内に進入し、その内側のラック25,26に噛合しながら奥に進入していく。このために、筐体30に対し前扉31を閉じて押し込んだとき、その押し込み量に応じて、装置本体1が受け部21,22側に進入しロックされる状態となり、最終的に前扉31を閉じた状態では、筐体30と前扉31との間に殆ど隙間が生じない状態となり、前扉31を筐体30に対しがたつきのない状態で堅固にロックすることができる。   Thus, in this locking device, as the front door 31 is closed with respect to the housing 30, the engagement gears 5 and 6 of the upper and lower gear portions 3 and 4 enter the receiving portions 21 and 22, While entering the racks 25, 26, they enter the back. For this reason, when the front door 31 is closed and pushed into the housing 30, the apparatus main body 1 enters the receiving portions 21 and 22 and is locked according to the pushing amount, and finally the front door. In a state where 31 is closed, there is almost no gap between the housing 30 and the front door 31, and the front door 31 can be firmly locked in a state where there is no backlash with respect to the housing 30.

また、受け部21,22内に設けたラック25,26の鋸歯はそのピッチが大きい場合でも、ラチェット歯車7,8と係合歯車5,6のギヤ比を例えば1:2のように小さくすることにより、係合歯車5,6を例えば半ピッチで進めることができ、細かい押し込み量でロックすることが可能となり、筐体30に対し前扉31を一層隙間なく且つがたつきなく施錠することができる。   Further, even when the pitch of the saw teeth of the racks 25 and 26 provided in the receiving portions 21 and 22 is large, the gear ratio between the ratchet gears 7 and 8 and the engagement gears 5 and 6 is reduced to, for example, 1: 2. Thus, the engaging gears 5 and 6 can be advanced at a half pitch, for example, and can be locked with a fine push-in amount, and the front door 31 can be locked to the housing 30 without any gaps and with less rattling. Can do.

図7〜図10は他の実施形態を示している。この例では、上部と下部の歯車部43,44のラチェット歯車47,48が、係合歯車45,46と同軸上に装着され、係合歯車45,46はラチェット歯車47,48より小径に形成される。   7 to 10 show other embodiments. In this example, the ratchet gears 47 and 48 of the upper and lower gear portions 43 and 44 are mounted coaxially with the engagement gears 45 and 46, and the engagement gears 45 and 46 are formed to have a smaller diameter than the ratchet gears 47 and 48. Is done.

すなわち、装置本体41は、上記と同様に、縦長の基枠42を有し、基枠42は、長尺の取付板42aと支持板42bを直角に曲折してL型アングル状に形成され、その支持板42bの上部と下部に突出部が背面側に突出して形成され、その部分に歯車部43,44の係合歯車45,46とラチェット歯車47,48が同軸上に同時に回転可能に軸支されている。   That is, the apparatus main body 41 has a vertically long base frame 42 as described above, and the base frame 42 is formed in an L-shaped angle by bending a long mounting plate 42a and a support plate 42b at right angles, Protruding portions are formed on the upper and lower portions of the support plate 42b so as to protrude to the back side, and the engaging gears 45, 46 and the ratchet gears 47, 48 of the gear portions 43, 44 are coaxially and simultaneously rotatable on the portions. It is supported.

また、各係合歯車45,46はラチェット歯車47,48より小径に形成されている。つまり、係合歯車45,46とラチェット歯車47,48のギヤ比を例えば1:2に形成することにより、係合歯車45,46が噛合する後述のラック65,66の1ピッチの1/2のピッチで施錠時のロックがかかるようにしている。   Further, the engagement gears 45 and 46 are formed with a smaller diameter than the ratchet gears 47 and 48. That is, by forming the gear ratio between the engagement gears 45 and 46 and the ratchet gears 47 and 48 to, for example, 1: 2, 1/2 of one pitch of racks 65 and 66 (described later) with which the engagement gears 45 and 46 mesh. The lock at the time of locking is applied at a pitch of.

さらに、上部と下部のラチェット歯車47,48には、各々その上方に、ラチェット爪49,50が軸49a,軸50aにより揺動可能に軸支され、上部と下部のラチェット爪49,50は各ラチェット歯車47,48に係合している。これにより、各ラチェット歯車47,48は、通常時、図7の反時計方向にラチェット爪9,10の係止作用により回転を阻止され、時計方向にのみ回転可能である。したがって、各ラチェット歯車47,48と同軸の係合歯車45,46は、通常時、図7の時計方向にのみ回転可能である。   Further, on the upper and lower ratchet gears 47, 48, ratchet pawls 49, 50 are pivotally supported on the upper and lower ratchet gears 47, 48 by shafts 49a, 50a, respectively. The ratchet gears 47 and 48 are engaged. Accordingly, the ratchet gears 47 and 48 are normally prevented from rotating in the counterclockwise direction of FIG. 7 by the latching action of the ratchet claws 9 and 10 and can be rotated only in the clockwise direction. Therefore, the engagement gears 45 and 46 coaxial with the ratchet gears 47 and 48 can normally rotate only in the clockwise direction of FIG.

さらに、図8のように、基枠42の支持板42bの外側に、支持板42bの長手方向にそって長尺の解錠部材51が摺動可能に配設され、その解錠部材51の上端と下端には、連結ピン49b、50bが軸支されている。その連結ピン49b、50bは、支持板42bに形成された長孔を通して外側から内側に挿通され、支持板42bの内側において、上部と下部の各ラチェット爪49,50の端部に連結されている。   Further, as shown in FIG. 8, a long unlocking member 51 is slidably disposed along the longitudinal direction of the support plate 42 b on the outside of the support plate 42 b of the base frame 42. Connecting pins 49b and 50b are pivotally supported at the upper and lower ends. The connecting pins 49b and 50b are inserted from the outside to the inside through long holes formed in the support plate 42b, and are connected to the end portions of the upper and lower ratchet claws 49 and 50 inside the support plate 42b. .

つまり、解錠部材51の上端と下端は、連結ピン49b、50bを介して、上部と下部のラチェット爪49,50の末端に連結され、解錠部材51を上下に摺動させたとき、ラチェット爪49,50がその軸49a,50aを軸にして揺動する。支持板42bの一部にガイドピン55が取り付けられ、解錠部材51に、そのガイドピン55が係合するガイド孔(長孔)が形成され、そのガイドピン55とガイド孔の係合により、解錠部材51は支持板42bに沿って所定の範囲で上下に摺動可能に支持される。   That is, the upper and lower ends of the unlocking member 51 are connected to the ends of the upper and lower ratchet claws 49 and 50 via the connecting pins 49b and 50b, and when the unlocking member 51 is slid up and down, the ratchet The claws 49 and 50 swing around the shafts 49a and 50a. A guide pin 55 is attached to a part of the support plate 42b, and a guide hole (long hole) for engaging the guide pin 55 is formed in the unlocking member 51. By engagement of the guide pin 55 and the guide hole, The unlocking member 51 is supported so as to be vertically slidable within a predetermined range along the support plate 42b.

解解錠部材51と支持板42bとの間にばね部材(コイルばね)54が掛けられ、解錠部材51はばね部材54により上方に付勢されている。したがって、通常時には、上部と下部のラチェット爪49,50はその先端の爪部をラチェット歯車47,48に係合させる状態にあり、解錠部材51を下方に移動させると、ラチェット爪49,50がその軸49a,50aを軸に上方に回動し、ラチェット歯車47,48との係合を外すように動作する。解錠部材51の中間部には、後述のカム板52と係合可能な係合部51aが形成され、支持板42bの対応箇所には、開口部42cが形成されている。   A spring member (coil spring) 54 is hung between the unlocking member 51 and the support plate 42 b, and the unlocking member 51 is biased upward by the spring member 54. Therefore, normally, the upper and lower ratchet pawls 49, 50 are in a state of engaging the pawl portions at the tips thereof with the ratchet gears 47, 48, and when the unlocking member 51 is moved downward, the ratchet pawls 49, 50 Rotates upward about the shafts 49a and 50a, and operates to disengage the ratchet gears 47 and 48. An engaging portion 51a that can be engaged with a cam plate 52, which will be described later, is formed at an intermediate portion of the unlocking member 51, and an opening 42c is formed at a corresponding portion of the support plate 42b.

さらに、基枠42の取付板42aの略中間部には、シリンダ錠53がその錠軸53aを基枠42の内側に挿入するように取り付けられる。シリンダ錠53の元部に突出した錠軸53aには、係合部52aを設けたカム板52が固定され、その係合部52aは錠軸53aの回動時、上記解錠部材51の係合部51aに係合可能である。   Further, a cylinder lock 53 is attached to a substantially middle portion of the attachment plate 42 a of the base frame 42 so that the lock shaft 53 a is inserted inside the base frame 42. A cam plate 52 provided with an engagement portion 52a is fixed to the lock shaft 53a protruding from the base portion of the cylinder lock 53, and the engagement portion 52a is engaged with the unlocking member 51 when the lock shaft 53a rotates. It can be engaged with the joint 51a.

一方、筐体30側に固定される受け部61,62は、図9に示すように、装置本体41の係合歯車45,46を進入させる進入凹部63,64が各々形成され、進入凹部63,64の内面底部にラック65,66が各々設けられる。受け部61,62は断面が略コ字状に形成され、上部に上板部67,68が形成され、内部に矩形断面形状の進入凹部63,64が形成され、ラック65,66がその底面に水平に形成されている。このラック65,66は各々上記係合歯車45、46と同じピッチの鋸歯を有し、その歯車と噛合可能である。進入凹部63,64は一方の端部に進入口を形成し、他方の端部も開口して形成される。また、上板部67,68の前部は、係合歯車45,46が進入しやすいように、少し上向きに曲げられている。   On the other hand, as shown in FIG. 9, the receiving portions 61 and 62 fixed to the housing 30 side are formed with entry recesses 63 and 64 for entering the engagement gears 45 and 46 of the apparatus main body 41, respectively. , 64 are respectively provided with racks 65, 66 at the bottom of the inner surface. The receiving portions 61 and 62 have a substantially U-shaped cross section, upper plate portions 67 and 68 are formed in the upper portion, entrance recesses 63 and 64 having a rectangular cross-sectional shape are formed inside, and the racks 65 and 66 are formed on the bottom surfaces thereof. It is formed horizontally. The racks 65 and 66 have saw teeth with the same pitch as the engagement gears 45 and 46, respectively, and can mesh with the gears. The entry recesses 63 and 64 are formed such that an entrance is formed at one end and the other end is also opened. Further, the front portions of the upper plate portions 67 and 68 are bent slightly upward so that the engagement gears 45 and 46 can easily enter.

上記構成の施錠装置は、図10に示すように、上記と同様にその装置本体41が、遊技機における例えば合成樹脂製の前扉31の内側に、シリンダ錠53の先端を前面に露出させ、装置本体41を遊技機の筐体30側に突出した状態に、縦方向に取り付けられる。一方、筐体30の内側の装置本体41に対応した上下位置(側壁の一部)には、受け部61、62がその進入凹部63,64の進入口を前方に向けて、固定ねじなどで固定される。   As shown in FIG. 10, the locking device having the above-described configuration is such that the device main body 41 exposes the front end of the cylinder lock 53 on the front surface inside the front door 31 made of, for example, a synthetic resin in the gaming machine, The device main body 41 is attached in the vertical direction so as to protrude toward the housing 30 side of the gaming machine. On the other hand, in the vertical position (part of the side wall) corresponding to the apparatus main body 41 inside the housing 30, the receiving portions 61 and 62 are directed forward with the entrances of the entrance recesses 63 and 64 with a fixing screw or the like. Fixed.

この遊技機用施錠装置は、遊技機における前扉31を筐体30に対し閉じると、図10に示すように、装置本体41の上部と下部の歯車部43,44の係合歯車45,46が筐体30側の上部と下部の受け部61,62の進入凹部63,64内に進入する。   In this gaming machine locking device, when the front door 31 of the gaming machine is closed with respect to the housing 30, the engaging gears 45, 46 of the upper and lower gear portions 43, 44 of the apparatus main body 41 are shown in FIG. Enters the recesses 63 and 64 of the upper and lower receiving portions 61 and 62 on the housing 30 side.

このとき、装置本体41の歯車部43,44の係合歯車45,46は、受け部63,64の内側のラック65,66に噛合して回転しながら進入していく。このとき、各歯車部43,44では、各係合歯車45,46と同軸上のラチェット歯車47,48が図10の時計方向にのみに回転し、ラチェット爪49a,50aに作用により逆方向には回転しない。このため、係合歯車45,46はラック65,66上を前進方向(図10の右方向)のみに回転しながら進み、前扉31が筐体30に密に閉鎖されたとき、その閉鎖状態がロックされる。   At this time, the engagement gears 45 and 46 of the gear portions 43 and 44 of the apparatus main body 41 are engaged with the racks 65 and 66 inside the receiving portions 63 and 64 and enter while rotating. At this time, in each of the gear portions 43 and 44, the ratchet gears 47 and 48 coaxial with the respective engagement gears 45 and 46 rotate only in the clockwise direction in FIG. 10, and reversely act on the ratchet claws 49a and 50a. Does not rotate. For this reason, when the engagement gears 45 and 46 move on the racks 65 and 66 while rotating only in the forward direction (right direction in FIG. 10), and the front door 31 is tightly closed by the housing 30, the closed state is established. Is locked.

また、係合歯車45,46がラック65,66上を噛合して前進するとき、後退方向への動きはラチェット歯車47,48により阻止されるが、係合歯車45,46とラチェット歯車47,48のギヤ比は例えば1:2のように、ラチェット歯車47,48の歯数がより多く設定されている。このため、係合歯車45,46がラック65,66上を噛合して進むとき、ラチェット歯車47,48の歯の進行度は、この場合、係合歯車45,46の2倍と多くなる。したがって、例えばラック65,66のピッチが1mmと比較的大きいピッチであっても、係合歯車65,66の移動ピッチは0.5mmという細かいピッチでロックすることができる。このため、ラック65,66、及び係合歯車45,46の歯は、比較的大きくして強度を上げて形成することができる。   Further, when the engagement gears 45 and 46 move forward while meshing on the racks 65 and 66, the backward movement is prevented by the ratchet gears 47 and 48, but the engagement gears 45 and 46 and the ratchet gear 47, The gear ratio of 48 is set so that the number of teeth of the ratchet gears 47 and 48 is larger, for example, 1: 2. For this reason, when the engagement gears 45 and 46 are engaged with each other on the racks 65 and 66, the progress of the teeth of the ratchet gears 47 and 48 is twice as large as that of the engagement gears 45 and 46 in this case. Therefore, even if the racks 65 and 66 have a relatively large pitch of 1 mm, for example, the engagement gears 65 and 66 can be locked at a fine pitch of 0.5 mm. For this reason, the teeth of the racks 65 and 66 and the engagement gears 45 and 46 can be formed relatively large to increase the strength.

このように、係合歯車45,46がラック65,66上を噛合して前進しながら、前扉31が筐体30に対し閉じられるが、装置本体41の係合歯車45,46が、ラック65,66の鋸歯の半ピッチという細かい押し込み量で、装置本体41が受け部61,62に対し徐々にロックされていくため、最終的に前扉31を閉じた状態では、扉と筐体の間に殆ど隙間が生じず、前扉31はがたつきのない状態で筐体30に対し堅固にロックされる。   As described above, while the engagement gears 45 and 46 mesh and move forward on the racks 65 and 66, the front door 31 is closed with respect to the housing 30, but the engagement gears 45 and 46 of the apparatus main body 41 are Since the apparatus main body 41 is gradually locked with respect to the receiving portions 61 and 62 with a small pressing amount of half pitch of the saw teeth of 65 and 66, when the front door 31 is finally closed, the door and the casing There is almost no gap between them, and the front door 31 is firmly locked to the housing 30 in a state where there is no backlash.

前扉31を解錠する場合は、キーをシリンダ錠53に差し込みその錠軸53aを回し、カム板52を回転させると、カム板52の回転により、カム板52の係合部52aが同方向に回動して、支持板42bの開口部42cを通して、解錠部材51の係合部51aに係合し、それを下方に摺動させる。このとき、解錠部材51が下降すると、その上端と下端に連結されたラチェット爪49,50が図10の反時計方向に回動し、ラチェット爪49,50とラチェット歯車47,48の係合が外れる。   When unlocking the front door 31, when the key is inserted into the cylinder lock 53 and the lock shaft 53a is rotated to rotate the cam plate 52, the engagement portion 52a of the cam plate 52 is rotated in the same direction by the rotation of the cam plate 52. To the engagement portion 51a of the unlocking member 51 through the opening 42c of the support plate 42b, and slide it downward. At this time, when the unlocking member 51 is lowered, the ratchet pawls 49 and 50 connected to the upper and lower ends of the unlocking member 51 are rotated in the counterclockwise direction in FIG. 10, and the ratchet pawls 49 and 50 are engaged with the ratchet gears 47 and 48. Comes off.

これにより、ラチェット歯車47,48がフリーな状態となり、上下の歯車部43,44の係合歯車45,46のロックが解除され、図示しない開方向への付勢手段あるいは開操作により、係合歯車45,46が受け部61,62のラック65,66上を回転しながら、進入凹部63,64内から退出し、前扉31は開放される。   As a result, the ratchet gears 47 and 48 become free, the locks of the engagement gears 45 and 46 of the upper and lower gear portions 43 and 44 are released, and the engagement gears 45 and 46 are engaged by an urging means or an opening operation in an opening direction (not shown) While the gears 45 and 46 rotate on the racks 65 and 66 of the receiving portions 61 and 62, the gears 45 and 46 retreat from the entry recesses 63 and 64, and the front door 31 is opened.

以上説明したように、本発明の遊技機用施錠装置によれば、前扉を筐体に対し閉じると、装置本体の歯車部が受け部内の進入凹部に進入して、受け部内のラックに噛合しながら進み、装置本体を取り付けた前扉が、受け部を設けた筐体に対しロックされる。このとき、装置本体の歯車部の係合歯車は、受け部内に進入してラチェット歯車の作用により後退不可能にロックされ、前扉を筐体に対して閉じる動作に応じて、係合歯車が受け部のラックに噛合して進みロックされるから、前扉を筐体に対し押し付けるように閉鎖して施錠した場合、前扉と筐体の間に殆ど隙間が生じず、前扉をがたつきのない状態で、堅固に施錠することができる。   As described above, according to the gaming machine locking device of the present invention, when the front door is closed with respect to the housing, the gear portion of the device body enters the entry recess in the receiving portion and meshes with the rack in the receiving portion. Then, the front door to which the apparatus main body is attached is locked to the housing provided with the receiving portion. At this time, the engagement gear of the gear portion of the apparatus main body enters the receiving portion and is locked so as not to be retracted by the action of the ratchet gear, and the engagement gear is moved according to the operation of closing the front door with respect to the housing. Since it is engaged and locked with the rack of the receiving part, when the front door is closed and locked so as to press against the housing, there is almost no gap between the front door and the housing, and the front door is rattled. It can be locked firmly without sticking.

また、係合歯車とそれに噛合するラチェット歯車のギヤ比を1より大きく設定することにより、係合歯車がラック上を進む際、ラックの1ピッチより小さいピッチで係合歯車をロックすることが可能となり、前扉の筐体に対する細かい押し込み量で前扉をロックすることが可能となり、筐体に対し前扉を一層隙間なく且つがたつきなく施錠することができる。   In addition, by setting the gear ratio of the engagement gear and the ratchet gear meshing with it larger than 1, it is possible to lock the engagement gear at a pitch smaller than 1 rack pitch when the engagement gear moves on the rack.
