The parts 65m and 70m are urged in the direction in which they approach each other. The first locking body 65 has a claw-shaped first locking portion 67 and rotates around the first pivot shaft 66 in the arrow A1 direction (unlocking direction) and the arrow A2 direction (locking direction). It is provided as possible. The second locking body 70 has a claw-shaped second locking portion 73 and rotates around the second pivot shaft 72 in the direction of arrow B1 (unlocking direction) and in the direction of arrow B2 (locking direction). It is provided as possible. The directions of arrows A1, A2 and arrows B1, B2 are the thickness direction of front door 3.

  When the front door 3 is locked to the gaming machine body 1, as shown in FIG. 5A, the striker 61 is engaged and locked in the locking groove 64 of the first locking body 65. Thus, the first locking portion 67 of the first locking body 65 and the second locking portion 73 of the second locking body 70 are locked. For this reason, the first locking body 65 of the front door 3 is locked to the striker 61 of the gaming machine main body 1. In this case, the urging force of the urging member 75 urges the first locking body 65 in the arrow A1 direction, and the second locking body 70 is urged in the arrow B2 direction. And the latching state (lock state) of the 1st latching | locking part 67 of the 1st latching body 65 and the 2nd latching | locking part 73 of the 2nd latching body 70 is maintained with the urging | biasing force of the biasing member 75.

  When unlocking the front door 3 with respect to the gaming machine main body 1, if the key is rotated in one direction while being inserted into the key cylinder 38, the cam 62 (sub movable body) moves in one direction in conjunction with this. And the slider 60 (main movable body) moves in one direction (upward, arrow Y1 direction) by the cam piece 62c, and the second locking body 70 moves around the second pivot shaft 72 in the arrow B1 direction. It rotates in the unlocking direction. As a result, as shown in FIG. 5B, the first locking portion 67 of the first locking body 65 and the second locking portion 73 of the second locking body 70 are released.

  And the 1st latching | locking part 67 of the 1st latching body 65 moves to the arrow A1 direction (unlocking direction) along the guide part 70x, contacting the guide part 70x of the 2nd latching body 70. FIG.

  Furthermore, as shown in FIG. 6 (A), the biasing force of the biasing member 75 causes the first locking body 65 to rotate around the first pivot shaft 66 in the direction of the arrow A1 (unlocking direction). Turn around. As a result, as shown in FIG. 6B, the direction of the locking groove 64 of the first locking body 65 changes to the unlocking direction, and the locking groove 64 of the first locking body 65 and the striker 61 are engaged. The lock is unlocked. If the front door 3 is opened in this state, the front door 3 can be opened with respect to the gaming machine body 1. The arrow A1 direction, the arrow A2 direction, the arrow B1 direction, and the arrow B2 direction are directions along the thickness of the front door 3.

  What is necessary is just to push the open front door 3 toward the game machine main body 1 when locking. In this case, as can be understood from FIG. 6B, when the front door 3 is pushed in the direction of the arrow W <b> 2, the striker 61 hits the wall surface 64 f of the locking groove 64 of the first locking body 65. The first locking body 65 rotates around the first pivot shaft 66 in the arrow A2 direction (locking direction) while resisting the urging force. Therefore, in a state where the striker 61 is locked in the locking groove 64 of the first locking body 65, the first locking portion 67 of the first locking body 65 and the second locking of the second locking body 70. The part 73 is locked. In this case, the first locking body 65 of the front door 3 is locked to the striker 61 of the gaming machine body 1, and the urging force of the urging member 75 causes the first locking portion 67 of the first locking body 65 to The locked state of the second locking body 70 with the second locking portion 73 is maintained.

  According to this embodiment, the striker 61 (lock locking portion), which is the main component of the locking device 6, employs a single lock system that locks a single location in the height direction of the front door 3. Therefore, the number of parts can be reduced and the size can be reduced as compared with the prior art in which a locking device for locking the front door 3 and the gaming machine main body 1 at two points, the upper part and the lower part, is provided. In the unlikely event that a foreign object such as a wire is inserted, the probability that the wire or other foreign material touches the various parts constituting the locking device 6 is reduced. Therefore, it becomes advantageous for suppressing fraud.

  Further, the features of this embodiment will be described. That is, as shown in FIGS. 3 and 4, the length connecting the upper end surface 3u of the front door 3 and the center PC of the operation unit 5 with the shortest distance is LA. The center point height of the length LA in the height direction is defined as PE. The height position M of the striker 61 (lock locking portion) that performs the locking function of the locking device 6 is provided in a region between the center point height PE and the operation portion 5. In other words, according to the present embodiment, when the length connecting the upper end surface 3u of the front door 3 and the center PC of the operation portion 5 with the shortest distance is LA and the length LA is 100%, the locking device 6 The height position M of the striker 61 (lock locking portion) that performs the locking function is provided in a region of 15 to 45% relative to the upper side from the center PC of the operation portion 5. In this case, when the above-mentioned length LA is 100%, the striker 61 (lock locking portion) that performs the locking function of the locking device 6 is 15-30% relative to the upper side from the center PC of the operation unit 5. It is preferable that it is provided in the region of 30% or 30% to 40%.

  When the above-described length LA is 100%, the length connecting the upper end surface 3u of the front door 3 and the striker 61 (lock locking portion) that performs the locking function of the locking device 6 with the shortest distance is LU. The length LU occupies 85 to 55% of the length LA (LA> LU> LB). In other words, when the length connecting the upper end surface 3u of the front door 3 and the center PC of the operation unit 5 with the shortest distance is LA, 85 to 55% of the length LA is occupied from the upper end surface 3u of the front door 3. In the region, the striker 61 (lock locking portion) that performs the locking function of the locking device 6 is not provided.

  According to the present embodiment in which the configuration described above is employed, the length connecting the upper end surface 3u of the front door 3 and the center PC of the operation unit 5 with the shortest distance is LA, and the length LA is 100. %, The height position M of the striker 61 (lock locking portion) that performs the locking function of the locking device 6 is provided in an area of 15 to 45% relative to the center PC of the operation portion 5 upward. ing. According to such a present Example, the fraudulent person pulls the operation part 5 of the front door 3 compulsorily (the arrow X1 direction shown in FIG. 4), and the front door 3, the gaming machine main body 1, When an illegal act is performed in order to forcibly form the gap Δt, the gap width of the gap Δt can be made as small as possible even when the gap Δt is formed. Therefore, it is advantageous for suppressing an illegal act starting from the fact that an unauthorized person pulls the operation unit 5.

  In addition, when the locking device 6 is a single lock system in which the front door 3 is locked to the gaming machine main body 1 in one place, a striker 61 (lock locking portion) that performs the locking function of the locking device 6 is positioned. In particular, if the operation unit 5 is too close, the distance between the upper end surface 3u of the front door 2 and the striker 61 (lock locking unit) that performs the locking function of the locking device 6 becomes excessive. As a result, when the opposite side of the operation unit 5, that is, the upper end surface 3u side of the front door 3 is forcibly opened by an unauthorized person, there is a gap between the front door 2 and the gaming machine body 1 even with a small load. There is a risk that it will be formed. For this reason, it is not preferable that the striker 61 (lock locking portion) that performs the locking function of the locking device 6 is positioned too close to the operation portion 5. Therefore, as described above, the striker 61 (lock locking portion) that performs the locking function of the locking device 6 is provided in the region of 15 to 45% relative to the upper side from the center PC of the operation portion 5. It is preferable.

  However, unlike the lower end surface 3 d side of the front door 3, the protruding operation unit 5 that tends to be a starting point of an illegal act involving pulling is not provided on the upper end surface 3 u side of the front door 3. Further, the fraudulent act on the upper end surface 3u side of the front door 3 is different from the fraudulent act on the operation unit 5 on the lower end surface 3d side of the front door 3, and it is easy for the surveillance camera, surrounding players, store clerks, etc. The frequency of actions is relatively low.

  According to the present embodiment, as described above, the amount of protrusion of the operation portion 5 from the surface 3f of the front door 3 is ΔX, the maximum diameter of the operation portion 5 is ΔD, and the striker 61 that performs the locking function of the locking device 6 is achieved. Assuming that the length between the (lock locking portion) and the axis PC of the operation portion 5 is LB, as can be understood from FIG. 4, the relationship is LB> ΔX and the relationship LB> ΔD. Furthermore, the striker 61 that performs the locking function of the locking device 6 is located above the uppermost end 5x of the operation unit 5 and projects the operation unit 5 in the vertical direction from the front surface 3f of the front door 3 toward the back surface. The striker 61 that performs the locking function of the locking device 6 is not located in the projected portion.

  Model tests were conducted on model products. Since this model product is not provided with the operation unit 5, it is assumed that the lower end surface is 3d '(see FIG. 3). In this test, the height dimension of the model product was set to 660 millimeters (dimension between 3u-3d '). Further, a striker 61 (lock engaging portion) that performs the locking function of the locking device 6 is disposed above the lower end surface 3d 'by a distance LE (260 millimeters). That is, the distance LE in the model test corresponds to a distance connecting the striker 61 (lock locking portion) that performs the locking function of the locking device 6 and the center PC of the operation unit 5 in the shortest distance in the actual gaming machine.

  In the model test described above, a load of 50 N was applied to the lower end (lower end surface 3d ') of the front door 3 in the tensile direction so as to form a gap between the front door 3 and the gaming machine body 1. At this time, the gap width of the gap Δt formed between the front door 3 and the gaming machine main body 1 was 1 millimeter. Further, when a load of 100 N was applied to the lower end (lower end surface 3d ′) of the front door 3, the gap width of the gap Δt formed between the front door 3 and the gaming machine body 1 was 1.5 millimeters. . As a countermeasure against fraud, it is preferable that the gap width is small. However, when a load of 100 N is applied, the gap width is considered to be within a range of 3 millimeters. When the front door 3 is pulled with a person standing, it is estimated that it corresponds to 100N.
