Description

  The present invention relates to a pachinko gaming machine having a structure in which a game area of a game board is double covered from the front by a front frame and an intermediate frame.

Some pachinko gaming machines have a structure in which a front frame is mounted on a support frame that supports a game board. The front frame supports a transparent front window and can be operated between a closed state that covers the game board from the front and an open state that moves forward compared to the closed state. This pachinko machine is equipped with a front frame locking mechanism. This front frame locking mechanism prohibits the front frame from being operated from the closed state to the open state based on locking the front frame to the closed state, and operates the front frame from the closed state to the open state. It is mounted for the purpose of preventing fraudulent acts such as bending the obstacle nail of the game board with fingers. However, when an unauthorized person forcibly operates the front frame from the closed state to the open state while the front frame is locked, a gap may be generated between the front frame and the support frame. For this reason, it is not possible to eliminate the possibility of fraudulent acts such as inserting a piano wire into the game board from the gap between the front frame and the support frame and bending the obstacle nail by hooking the piano wire on the game board's obstacle nail. .

When the intermediate frame 33 reaches the closed state from the open state, the intermediate frame lock fitting 41 passes rearward through the claw portion 39 of the intermediate frame lock plate 38, and the intermediate frame lock plate 38 is brought into the locked position by the spring force of the return spring. To rise. In the locked state of the intermediate frame lock mechanism, the claw portion 39 of the intermediate frame lock plate 38 is engaged with the intermediate frame lock fitting 38 from the front, and the intermediate frame 33 is locked in the closed state.

  As shown in FIG. 5, an operation lever 42 is connected to the intermediate frame lock plate 38. The operation lever 42 is covered by the front frame 4 so that it cannot be operated from the front when the front frame 4 is closed, and is exposed to be operable from the front when the front frame 4 is open. The operation lever 42 is for moving the intermediate frame lock plate 38 from the locked position to the unlocked position against the spring force of the return spring. The operator moves the front frame 4 while the intermediate frame 33 is locked. When the operation lever 42 is opened downward and the operation lever 42 is operated downward, the claw portion 39 of the intermediate frame lock plate 38 is detached from the intermediate frame lock fitting 41 based on the movement of the intermediate frame lock plate 38 from the lock position to the lock release position. When the operator operates the intermediate frame 33 forward in the unlocked state of the intermediate frame locking mechanism, the intermediate frame 33 rotates from the closed state to the open state, and the game area 29 of the game board 24 is opened.

  As shown in FIG. 6, a through-hole-shaped window portion 43 is formed in the front frame 4, and a cylindrical guard member 44 is inserted into the window portion 43. The guard member 44 is made of rubber and is in close contact with the inner peripheral surface of the window portion 43 by an elastic restoring force. A stopper 45 is joined to the rear end portion of the guard member 44, and the guard member 44 is extracted forward from the inner peripheral surface of the window portion 43 based on the stopper 45 coming into contact with the rear surface of the front frame 4. Is prevented.

  As shown in FIG. 6, an operation portion 46 is formed in the intermediate frame lock fitting 41. The operation portion 46 has a plate shape protruding forward from the intermediate frame 33, and is inserted into the through hole 4b in a closed state of the front frame 4 and the intermediate frame 33. This through hole 4b is formed in the reinforcing frame 4a of the front frame 4 so as to be positioned behind the window portion 43. In the state where each of the front frame 4 and the intermediate frame 33 is locked in the closed state, FIG. As shown by a solid line in FIG. 6, the front end portion of the operation portion 46 is in a retracted state in which it is movably inserted into the inner peripheral surface of the guard member 44 through the through hole 4b of the reinforcing frame 4a. In the retracted state of the operation unit 46, the front end surface of the operation unit 46 is positioned on the same plane as the front surface of the front frame 4, and the operator positions the operation unit 46 in the closed state of the front frame 4. Can be identified with the eye that the intermediate frame 33 is locked in the closed state.

  As shown by a two-dot chain line in FIG. 6, the operation portion 46 protrudes forward of the front frame 4 through the guard member 44 when the intermediate frame 33 is not operated in the closed state with the front frame 4 closed. The operator can visually identify that the intermediate frame 33 is not locked in the closed state by checking the position of the operation unit 46 with the front frame 4 as a reference in the closed state of the front frame 4. it can. The operation unit 46 can be operated from the front by the operator when the front frame 4 is closed, and the operator pushes the operation unit 46 from the protruding state to the retracted state when the front frame 4 is closed. Sometimes, the intermediate frame 33 is closed based on the pivot of the intermediate frame 33 about the shaft 34, and the intermediate frame locking mechanism locks the intermediate frame 33 in the closed state. The operating portion 46 is in close contact with the inner peripheral surface of the guard member 44 in the retracted state and the protruding state by the elastic restoring force of the guard member 44. It is impossible to insert a piano wire between the inner peripheral surfaces of 44.

According to the said Example 1, there exists the following effect.
An intermediate frame 33 is provided between the game board 24 and the front frame 4. The intermediate frame 33 moves independently of the front frame 4, and even when a gap is illegally generated between the front frame 4 and the inner frame 2 based on the force of the front frame 4 being operated. It is kept closed. For this reason, in order to illegally insert a piano wire into the game board 24, it is necessary to perform a highly difficult work of forcibly operating the intermediate frame 33 through an unauthorized gap between the front frame 4 and the inner frame 2. It becomes difficult to perform an illegal act of inserting a piano wire into the game board 24. When the intermediate frame 33 is locked in the closed state when the front frame 4 is closed, the operation unit 46 of the intermediate frame 33 is stopped in a predetermined retracted state. For this reason, it is identified that the intermediate frame 33 is not operated in the closed state based on the fact that the operation unit 46 is displaced forward from the retracted state with the front frame 4 in the closed state. The intermediate frame 33 can be operated to the closed state by operating the front frame 4 from the closed state to the open state.

  When the intermediate frame 33 is not operated in the closed state in the closed state of the front frame 4, the operation part 46 is protruded forward through the window part 43 of the front frame 4. For this reason, it is identified that the intermediate frame 33 is not operated in the closed state based on the operation unit 46 moving to the protruding state, and the operating unit 46 is retracted from the protruding state while the front frame 4 is closed. The intermediate frame 33 can be locked in the closed state by being pushed in. A rubber guard member 44 is fitted to the inner peripheral surface of the window 43, and the operation portion 46 is movably fitted to the inner peripheral surface of the guard member 44 so that the outer peripheral surface of the operation portion 46 is projected and retracted. Each of the states was brought into close contact with the inner peripheral surface of the guard member 44. For this reason, since the gap between the outer peripheral surface of the operation unit 46 and the inner peripheral surface of the window portion 43 is closed, the piano wire passes through the gap between the outer peripheral surface of the operation unit 46 and the inner peripheral surface of the window portion 43 from the front. It becomes impossible to perform cheating to insert.

  As shown in FIG. 7, a moving element 51 is inserted into the window 43 of the front frame 4 so as to be movable in the front-rear direction. An operation portion 52 is fixed to the front end portion of the moving element 51, and a spring receiver 53 is fixed to the rear end portion of the moving element 51. Each of the operating portion 52 and the spring receiver 53 has a hook shape protruding from the outer peripheral surface of the moving element 51. The outer peripheral surface of the moving element 51 is located between the spring receiver 53 and the front frame 4 and is rearward. A spring 54 is inserted, and a front spring 56 is inserted between the operation portion 52 and the front frame 4. Each of the rear spring 54 and the front spring 56 is composed of a compression coil spring, and the moving part 51 moves the operation portion 52 forward from the front frame 4 by both the spring force of the rear spring 54 and the spring force of the front spring 56. It is held in a protruding neutral state. In the neutral state of the moving element 51, each of the rear spring 54 and the front spring 56 is in a natural state, and each of the operation portion 52 and the spring receiver 53 is separated from the front frame 4.

  As shown in FIG. 7, a pressing portion 55 is formed on the intermediate frame lock fitting 41 of the intermediate frame 33. The pressing portion 55 has a plate shape protruding forward from the intermediate frame 33, and the pressing portion 55 is separated rearward from the spring receiver 53 of the moving element 51 in the closed state of the front frame 4 and the intermediate frame 33. Based on this, the movable element 51 is held in a neutral state. The pressing portion 55 presses the spring receiver 53 forward when the intermediate frame 33 is not operated in the closed state with the front frame 4 closed, and the intermediate frame 33 is closed with the front frame 4 closed. In the case where it is not operated, the pressing portion 55 presses the spring receiver 53 forward, so that the movable element 51 is operated from the neutral state to the protruding state against the spring force of the spring 54. In the protruding state of the moving element 51, the rear spring 54 contracts without contracting the front spring 56, and the moving element 51 is urged rearward by the spring force of the rear spring 54.

  The mover 51 can be pushed from the front when the front frame 4 is closed. When the operation unit 52 of the mover 51 is pushed backward while the mover 51 is projected, the mover 51 is moved. Move from the protruding state to the retracted state. The retracted state of the mover 51 is a state in which the mover 51 has moved backward compared to the neutral state. In the retracted state of the mover 51, the front spring 56 contracts without the rear spring 54 contracting, and the mover 51 retracts. It is biased forward by the spring force. When the moving element 51 is pushed from the protruding state to the retracted state, the intermediate frame 33 moves to the closed state based on the fact that the operating force of the moving element 51 is transmitted to the intermediate frame 33 through the pressing portion 55, and the intermediate frame locking mechanism. Locks the intermediate frame 33 in the closed state. When the pushing operation force is removed from the operation portion 52 of the moving element 51 in the retracted state of the moving element 51, the moving element 51 moves forward by the spring force of the front spring 56 and returns to the protruding state.

  As shown in FIG. 7, a rubber cover 57 is fixed to the front frame 4. This cover 57 covers the operation part 52 of the moving element 51 from the front, and prevents a piano wire from being inserted through the space between the outer peripheral surface of the moving element 51 and the inner peripheral surface of the window part 43 from the front. The cover 57 has a bellows shape that can be expanded and contracted, and the movable element 51 is allowed to move between the protruding state and the retracted state based on the elastic expansion and contraction of the cover 57.

According to the said Example 2, there exist the following effects.
When the intermediate frame 33 is not operated in the closed state in the closed state of the front frame 4, the mover 51 is moved to the forward protruding state through the window 43 of the front frame 4. For this reason, it is identified that the intermediate frame 33 is not operated to the closed state based on the movement of the movable element 51 to the protruding state, and the movable element 51 is retracted from the protruding state while the front frame 4 is closed. The intermediate frame 33 can be locked in the closed state by being pushed in.

As shown in FIG. 8, the pressing portion 55 of the intermediate frame 33 comes into contact with the spring receiver 53 of the moving element 51 from the rear in the closed state of the front frame 4 and the intermediate frame 33, and the rear spring 54 moves. The spring receiver 53 of the child 51 is held in a state of being in contact with the pressing portion 55 based on urging backward. This moving element 51 is based on pushing the pressing portion 55 backward via the spring receiver 53 when the front frame 4 is operated in the closed state with the front frame 4 and the intermediate frame 33 opened. The rear spring 54 functions as a shock absorber when the intermediate frame 33 is pushed rearward. [Other invention 1] describes Example 3.
