Therefore, the operation portion main body 2 interposed between the operation portion 26 for the operator to operate and the lock portion 30 that locks the game board 2 by locking the lock receiving portion 33 of the game board 2.
7, the shaft 31, the lock member 25, and the like function as a transmission member that transmits the movement of the operation unit 26 to the lock unit 30.

Game board lock mechanism 2 having such a structure
4, when the operation portion 26 is moved up and down from the front surface side of the inner frame 5, as shown in FIG.
5 is positioned substantially horizontally and the lock portion 30 is the game board mounting portion 9
When the operation portion 26 is moved downward from the locked state in which the lock member 25 largely protrudes inward, one end of the lock member 25 is pushed down by the connecting portion 28 and the lock member 25 rotates counterclockwise about the shaft 31. To do. Therefore, the protruding length of the lock portion 30 protruding into the game board mounting portion 9 is shortened, and the lock portion 30 is converted into the unlocked state. On the other hand, when the operating portion 26 is moved upward from this unlocked state, one end of the lock member 25 is pulled up by the connecting portion 28, so that the lock member 2
5 rotates clockwise about the shaft 31. Therefore, while the lock portion 30 descends, it largely projects into the game board mounting portion 9 and is converted into a locked state.

In this way, when the lock portion 30 largely projects into the game board mounting portion 9, the lock receiving portion 33 provided on the side surface of the game board 2 is located at the position where the lock portion 30 projects. The protruding lock portion 30 engages with the lock receiving portion 33 of the game board 2 to lock the game board 2 (lock state). The lock receiving portion 3 shown in FIG.
3 is formed as a V-shaped groove, and is formed by gradually decreasing the inner diameter in accordance with the direction in which the protrusion length increases while the lock portion 30 moves. Therefore,
When the lock portion 30 projects to a sufficient projecting length, the front and rear surfaces or ridges of the lock portion 30 are simultaneously engaged with the front and rear inner edges or inner surfaces of the V-shaped groove, whereby the front and rear position of the game board 2 is changed. It locks in a state where it is aligned with a predetermined position, and prevents back and forth movement.

In the locked state described above, the operating portion 26
Moving upward, the lock member 25 rotates counterclockwise about the shaft 31 to increase the lock portion 30 and decrease the protrusion length, and when the lock member 30 rotates sufficiently, the lock portion 30 locks the lock receiving portion. 33 is released, and the lock is released by this (unlocked state).

The game board lock mechanism 24 may have any structure as long as the game board 2 can be locked or unlocked in the game board mounting portion 9 by operating the operation portion 26 from the front surface of the inner frame 5. For example, the game board lock mechanism 2 shown in FIG.
4, a pressing protrusion 34 is formed at the tip of the lock portion 30 of the lock member 25, and the lock receiving portion 33 has an inclined receiver inclined in a direction of pressing the game board 2 to the rear side of the rear game board mounting portion 9. The part 35 is formed. In this game board lock mechanism 24, when the lock member 25 is rotated by operating the operation portion 26 to sufficiently engage the lock portion 30 with the lock receiving portion 33 and lock, the engagement depth increases. The pressing protrusion 34 gradually and strongly presses the inclined receiving portion 35.
Therefore, when the lock part 30 is engaged and locked sufficiently deeply, the pressing projection 34 presses the inclined receiving part 35 to the rear of the inner frame 5, whereby the game board 2 is sufficiently retracted and forced to a predetermined position. It is moved and there is no back and forth play.

The game board lock mechanism 24 shown in FIG.
The lock portion 30 of the lock member 25 is bifurcated, and the lock receiving portion 33 includes an engagement piece 36 that is inserted between the two lock portions 30 and fits between the lock portions 30. In this game board lock mechanism 24, when the lock member 25 is rotated by operating the operation portion 26, the bifurcated lock portion 30 enters the recess with the engagement piece 36 sandwiched therebetween. Then, when the lock receiving portion 33 rotates sufficiently, the bifurcated lock portion 30 sandwiches and locks the engaging piece 36, and regulates the front-back position of the game board 2. Therefore, when the lock portion 30 is engaged and locked sufficiently deeply, the game board 2 is forcibly moved to a predetermined position by this, and is locked in this state.

In this way, the inner frame 5 provided with the game board lock mechanism 24 for locking the game board 2 and the temporary fixing mechanism 20 is locked to the other side of the outer frame 6 by the hook which constitutes a part of the locking device. The member is locked on the free end side.

Further, the clear member storage frame 3 can be manually moved to the inner frame 5 if the game board lock mechanism 24 is converted to the locked state.
It is closed to a predetermined position (normal position where it can be operated without hindrance) by lightly pressing it to the side, and the free end side is locked to the other side of the inner frame 5 by another hook 37 that constitutes the locking device. On the other hand, if the game board lock mechanism 24 remains in the unlocked state, even if the game board lock mechanism 24 is pressed by hand, the clear member storage frame closing operation restricting mechanism 38 prevents the operator from closing the game board to a predetermined position, which allows the operator to play the game board. The lock mechanism 24 is configured to notify that the lock mechanism 24 is in the unlocked state. Then, when the clear member storage frame 3 is closed to a predetermined position, the hook 37 of the locking device locks the clear member storage frame 3, and when it is not closed to the predetermined position, it is not locked. Such locking of the inner frame 5 and the clear member storage frame 3 is such that when the key inserted into the key hole of the cylinder lock 39 provided on one side of the upper part of the inner frame 5 is rotated to one side, the inner frame 5 is rotated to the other side. Then, the clear member storage frame 3 is unlocked.

Next, the clear member storage frame 3 is provided at a position where the inner frame 5 and the clear member storage frame 3 are opposed to each other, that is, on the front side of the inner frame 5 and the back side of the clear member storage frame 3. The clear member storage frame closing operation restricting mechanism 38 for restricting the closing operation of the above will be described in relation to the state of the game board lock mechanism 24.

The clear member storage frame 3 is a synthetic resin frame body having a plate glass 11 or a transparent plastic plate mounted as a clear member in the central opening, and on the back side thereof, as shown in FIG. A material 60 is provided, and a through hole 61 through which the hook 37 of the locking device penetrates is provided in a part of the reinforcing material 60, and an edge of the through hole 61 is used as an engaging portion of the hook 37, so that the clear member storage frame 3 is normally operated. When the hook 37 is rotated to the position and normally closed with respect to the inner frame 5, the protruding length of the hook 37 and the engaging claw portion 3 are set so that the hook 37 engages with the engaging portion of the reinforcing member 60.
The position of 7'is set and the front and rear positions of the engaging portion are set.

Further, in the present embodiment, a part of the reinforcing member 60 corresponding to the position where the operation portion 26 functioning as the movable contact portion 62 stops in the unlocked state is used as the fixed contact portion 63, and the operation portion 26 is A concave contact avoiding portion 64 capable of accommodating the protruding tip portion of the operating portion 26 is formed in a part of the reinforcing member 60 corresponding to the position where it stops in the locked state. As shown in FIG. 10, the portion of the reinforcing member 60 that functions as the fixed contact portion 63 is
The clear member storage frame 3 is arranged at a position where the clear member storage frame 3 comes into contact with the operation portion 26 (movable contact portion 62) in the unlocked state before closing to the normal position. On the other hand, the contact avoidance section 64 is shown in FIG.
As shown in FIG. 5, the clear member storage frame 3 is formed in a concave shape with a sufficient depth so as not to contact the operation portion 26 in the locked state when the clear member storage frame 3 is closed at the normal position.

Therefore, when the operation member 26 of the game board lock mechanism 24 is in the unlocked state and the clear member storage frame 3 which is wide open is manually pushed to the inner frame 5 side to start the closing operation, FIG. As shown in (b), before the clear member storage frame 3 reaches the normal position of the inner frame 5, the fixed contact portion 63 on the clear member storage frame 3 side of the operation portion 26 as the movable contact portion 62. This fixed contact portion 6 is brought into contact with the protruding tip portion.
3 and the movable contact portion 62 contact each other, the clear member storage frame 3
The closing action of is blocked at this point. Therefore, the front end portion of the clear member storage frame 3 is still protruding from the front surface of the inner frame 5, and an operator who is pressing the clear member storage frame 3 by hand to close it does not It is possible to recognize that the clear member storage frame 3 has not been closed to the predetermined position, that is, that the player has forgotten to lock the game board lock mechanism 24 and tried to close the clear member storage frame 3. Further, unless the clear member storage frame 3 is closed to the normal position by the contact between the fixed contact portion 63 and the movable contact portion 62, the hook 37 does not sufficiently penetrate into the through hole 61 of the reinforcing plate 60. There is no need to lock it.

The operator who notices that he / she has forgotten to lock opens the clear member storage frame 3 again and then operates the operation section 26 (in this embodiment, the operation section 26 is slid upward) to lock the game board lock mechanism 24. When converted to, the game board 2 is locked. Then, when the clear member storage frame 3 is pressed again by hand to perform the closing operation, the operation portion 26 (movable contact portion 62) faces the fixed contact portion 63 this time, as shown in FIG. It moves out of the contact position by moving upward from the contact position, and the operating portion 26 in this state
Since the recess-shaped contact avoiding portion 64 is formed at a position opposed to, the clear member storage frame 3 is allowed to close to the normal position sufficiently deep with respect to the inner frame 5. In this way, when the clear member storage frame 3 is rotated to the normal position and closed, the front surfaces of the clear member storage frame 3 and the inner frame 5 become substantially flush with each other, and the hook 37 penetrates the reinforcing plate 60. Hole 61
It penetrates deeply inside, and the engaging claw 37 'of the hook 37 engages with the edge of the through hole 61 by the bias of the spring to lock it. In this state, the operation portion 26 of the game board lock mechanism 24 is housed in the contact avoidance portion 64 and its movement is restricted. You will never unlock it. Therefore, as long as the clear member storage frame 3 is closed, the locked state of the game board 2 is reliably maintained.

In this way, if the player forgets to lock the game board lock mechanism 24, the clear member storage frame 3 cannot be closed to a predetermined normal position. Therefore, if the user clears the clear member storage frame 3 by hand, he / she immediately notices that the lock is forgotten. Although it is configured, a game board lock state display means 70 is provided so that the lock state can be visually confirmed before closing the clear member storage frame 3.

Game board lock status display means 70 shown in the drawing
Is a front running portion of the inner frame 5 to which the operation section 26 is slidably mounted, which appears when the operation section 26 is unlocked, and is unlocked at a portion covered by the operation section 26 when locked. The display "open" is marked. Therefore, if the operating unit 26 is operated to convert it to the locked state, the display of “open” cannot be seen by the operator as shown in FIG. 11B, but the operator forgets the lock and remains in the unlocked state. Then, as shown in FIG. 11A, “released” remains displayed, and the operator is visually displayed that the unlocked state (opened). Therefore, the operator can confirm the lock of the game board 2 only by confirming the above-mentioned "open" display when closing the clear member storage frame 3.

The game board lock status display means 70 is
Any configuration may be used as long as the display changes between the locked state and the unlocked state of the game board lock mechanism 24 and the operator can visually confirm the locked state of the game board 2. For example, a portion that is covered by the operation portion in the locked state and that appears when the operation portion is disengaged in the unlocked state may be colored red.

Next, the game board 2 to be mounted on the game board mounting portion 9 of the inner frame 5 will be described. The game board 2 is shown in FIG.
As shown in FIG. 2 (a), a game section 10 is formed on the front surface by partitioning with a partitioning member such as a guide rail.
There are innumerable obstacle nails 40, prize winning devices 41, etc. in 0. The game board 2 according to the present embodiment is formed by molding a synthetic resin into a hollow substantially rectangular plate-like body as a whole, and a substantially circular game portion 10 is formed in a concave shape in a front surface portion 43 surrounded by edge surface portions 42 on the four vertical and horizontal directions. The curved surface between the circular inner edge of the front surface portion 43 and the outer edge of the game surface 44 functions as a partition member, and an inner guide rail 45 is provided inside a part of this partition member.
Is fixed to form a ball guide flow path 46, and an out port 47 is opened at the lowest position in the game section 10 surrounded by the inner guide rail 45 and the partition member, and an obstacle nail is provided in the game section 10. 40 are planted and a center accessory 48, a variable display device, and a winning device 41 are provided.

In the present embodiment, an out-ball flow-down path 49 is formed in the lower portion on the back side of the out port 47 so that the out-ball can be processed within the thickness of the game board 2. Further, a convex portion 50 for supporting the root of the obstacle nail 40 is integrally formed on the back side of the game surface 44 on which the obstacle nail 40 is planted. Therefore, even if the obstacle nail 40 made of metal is implanted on the game surface 44 made of synthetic resin (it may be insert-molded or separately driven), the obstacle nail 40 can be firmly supported, and at the time of nail adjustment. It will not be damaged by impact.

In addition, the game board 2 in this embodiment,
A temporary support mechanism 20 that can be held by the game board mounting portion 9 is provided on the same center line on one side corresponding to the bearing portion (shaft hole 23) provided on the game board mounting portion 9 and that can be held by the game board mounting portion 9 on the other side. The attracted portion 22 that constitutes a part of the above is provided, and the lock receiving portion 33 that constitutes a part of the game board lock mechanism 24 is provided.

Even if the parts are projected at a position where there is a small gap between the opening of the mounting portion 9 and the opening edge, it is not necessary to perform alignment work so that these protruding members enter the opening 16 of the game board mounting portion 9. By simply rotating the game board 2 about the rotation support shaft 51, the protruding portion is automatically inserted into the opening 16. Therefore, also in this respect, it contributes to facilitating the mounting work of the game board 2.

If the clearance between the opening 16 of the game board mounting portion 9 and the member projecting to the back side of the game board 2 can be set smaller than the conventional design, the back side of the game board 2 can be set. Since the members protruding to the front can be arranged in a wider range than in the past, the degree of freedom in design is increased, and the fun of the game can be enhanced by devising the arrangement of the parts in the game section 10. Further, a wiring cord is provided on the back side of the game board 2, and it may be necessary to pass the wiring cord into the opening 16 of the game board mounting portion 9, but one side of the game board 2 is rotatably supported. When the wiring cord is pivotally attached by the shaft 51, the work of passing the wiring cord through the opening 16 can be performed efficiently and safely with both hands.

When the game board 2 is rotated sufficiently, the edge surface portion 42 of the game board 2 contacts the positioning portion 17 to regulate the vertical and horizontal positions of the game board 2 and guide the game board 2 to a predetermined position. It In addition, when the game board 2 is sufficiently rotated and pressed,
The rear edge of the edge surface portion 42 contacts the positioning portion 17 and the retracted position is also regulated. Furthermore, the game board 2 is the positioning portion 1
When guided to a predetermined position by the action of 7, the attracted portion 22 provided on the back side of the game board 2 comes into contact with or comes close to the permanent magnet 21 on the game board mounting portion 9 side, so that the permanent magnet 21 is attracted. The attracted portion 22 is sucked by the force. Therefore, even if the operator releases his or her hand, the game board 2 is temporarily fixed in the game board mounting portion 9 by the attraction force of the permanent magnets 21 and holds that state. Therefore, if the operator first pushes the game board 2 into the game board mounting portion 9, he / she can release his / her hands with peace of mind, and can perform other work as necessary.

After the game board 2 is temporarily fixed by the above-mentioned temporary fixing operation, the operation portion 26 of the game board lock mechanism 24 provided on the front surface of the inner frame 5 is then operated. When the operation portion 26 is operated, as described above, the lock member 25 of the game board lock mechanism 24 rotates about the shaft 31, and the lock portion 30 engages with the lock receiving portion 33 of the game board 2, The game board 2 can be locked at a predetermined position. Further, when the operation panel 26 is operated to convert the game board lock mechanism 24 into the locked state, the display of “open” is displayed on the operation panel main body 27.
Covered by.

After the game board 2 is locked, the remaining work such as connecting the wiring cord of the member attached to the game board 2 to a predetermined connector is performed. When performing this work, the work will be performed on the back side of the inner frame 5,
Since the game board 2 is already locked to the inner frame 5 side, it is not necessary to take an unnatural posture such as pressing the game board 2 with one hand, and both hands can work in the natural posture on the back side of the inner frame 5. You can
