Next, each operation from the assembly of the game board 1 to the inspection will be described. When assembling the game board 1, first, the game board 2 is set on the carriage 35 on the transfer line 32, and the parts shelf is
A required game part 37 is taken from 38, and the game part 37 is mounted in accordance with the required mounting hole 18 of the game board 2 on the carriage 35.
When the skilled worker has completed the predetermined work,
35 are sequentially sent to the lower side in the direction of arrow a, and each lower side worker similarly mounts the next game component 37 on the game board 2. Game board
When the mounting of each game component 37 from the front side of 2 is completed, the game board 2 on the cart 35 is inverted, and the relay board 21, the back cover 20, etc. are mounted on the back side of the game board 2, and each game component is mounted. After the lead wires connected to the electrical components 37 are drawn out and connected to the respective male connectors 27 of the relay board 21, the control board 26 containing the protection cover 25 is attached to the back cover 20. Finally, the female connector 28 of the flat cable 23 connected to the relay board 21 is temporarily fixed by the pair of locking claws 30 of the temporary fixing means 29.

At this time, if the flat cable 23 side of the female connector 28 is aligned with the pair of locking claws 30 and the flat cable 23 side is pulled toward the game board 2, each locking claw 30 is elastically deformed and the female connector 28 is deformed. Since the mold connector 28 fits between the grooves 31 of the locking claws 30, the female connector 28 can be temporarily and easily temporarily fixed. This completes the assembly work of the game board 1. When the assembling work is completed, the bogie 35 is sequentially pushed downward while the gaming board 1 is mounted, and the bogie 35 is moved along the transport line 32 to the transfer means 40 side of the inspection zone B. In the inspection zone B, the game board 1 is automatically inspected according to the sequence shown in the flowchart of FIG.

When the carriage 35 with the game board 1 mounted thereon reaches the transfer means 40 as shown in FIG. 2 and the detection means (not shown) detects the carriage 35 (step S1), the transfer means 40 Is actuated to clamp the game board 1 on the carriage 35 with the pair of clamp claws 63, and the swing board 59 swings the game board 1 and so on.
After 1 is raised, the moving body 57 moves along the ceiling rail 56 and inserts the gaming board 1 between the pair of guide rails 48 and 49 of the supply means 39 (step S2). After taking out the game board 1, the carriage 35 moves below the supply means 39 and the like on the transport rail 34.
And is sent to the assembly work zone A side. Therefore, the carriage 35 can be circulated without stagnation. Further, since the inspection zone B is located above the transport line 32, there is no waste of space and a narrow space can be effectively used.

When the transfer operation of the game board 1 by the transfer means 40 is completed (step S3), the drive roller 51 of the supply means 39
Is rotated to supply the gaming board 1 to the inspection position C while standing up (step S4). After the detecting means (not shown) detects the gaming board 1 at the inspection position C, the positioning means 53 operates. The positioning tool 54 is raised, and the upper end thereof is in the notch 19 of the game board 2.
And the game board 1 is locked at the inspection position C, whereby the supply of the game board 1 is completed (step S5). Next, the operation shifts to the inspection operation by the inspection means 42 (step S6). At the time of this inspection, first, the position detection unit 66 detects the female connector 28 of the game board 1, and the drive mechanism 65 moves the inspection head 64 vertically and horizontally by the control of the tracking control unit 67 according to the detected position. Move to match female connector 28. Then, the inspection head 64 advances, and each contact 41 at the tip of the inspection head 64 comes into contact with each contact of the female connector 28, and the game board
Each electrical component on the 1 side is connected to the inspection means 42 side.

Next, an inspection signal is sequentially sent from the transmission section 68 of the inspection means 42 to each electric component on the game board 1 side via each contact 41 of the inspection head 64, the female connector 28, the relay board 21, the lead wire and the like. , And the signal is received by the receiving unit 69 side, and the damage of each electric component, the disconnection of the lead wire, the connection failure, and the like are sequentially checked. For example, in the case of the liquid crystal display device of the variable symbol display device 5, a predetermined inspection signal, for example, a current signal similar to that at the time of normal operation is sequentially passed to each of the segments of the symbol display portion composed of seven segments, Each segment is checked for abnormalities. When a non-contact type detection switch is used as the detection switch of the ball input chuckers 7 to 10, a current signal similar to that at the time of normal operation is passed as an inspection signal to check for an abnormality.

When a normally open movable contact type detection switch is used as the detection switch of the ball-intake chuckers 7 to 10, the detection switch is in a normally open state, and inspection cannot be performed by merely passing a current. , Two or three levels of different test signals are supplied to the detection switch, and the quality of the detection switch is checked based on whether or not the contacts are conductive. For example,
If the contact between the contacts is turned on by a test signal of a low voltage equal to or lower than a predetermined level, the interval between the contacts is too small. Also, when a high voltage of a certain level or more is applied within a range where the contacts do not melt or fuse, if the contacts do not conduct at all despite the fact that the contacts normally conduct and turn on, the contact between the contacts does not occur. The spacing will be too wide. Therefore, by sending inspection signals of different voltages from the transmission unit 68 to the detection switch, it is possible to inspect the abnormality of the normally-open movable contact type detection switch.

After receiving the signals from the game board 1 at the receiving section 69 of the inspection means 42, the pass / fail judgment section 70 judges whether or not each electric component of the game board 1 has an abnormality, and specifies an abnormal location. (Step S7) The data of the determination result is stored in the output unit 71, and is displayed or recorded on a cathode ray tube, recording paper, or the like.
When the inspection of the game board 1 by the inspection means 42 is completed, the positioning means 53 releases the positioning of the game board 1, and the distribution means 45 and the like are operated according to the result of the quality judgment, and the game board 1 is transported to the non-defective product transport means 43 or the defective product transport means 44 side. That is, if the judgment result is a non-defective product, the supplying means 3
9, each drive roller 51, 88 of the distribution means 45 and the good product transport means 43
Are rotated to guide the game board 1 after the inspection to the non-defective goods transport means 43 via the distribution means 45 (steps S8 and S9).
It is conveyed to the lower side by the rotation of the drive roller of the non-defective product conveying means 43, and is sent to the product conveying means 46 via the merging means 47 (step S10).

If the result of the determination is defective, the defective game board 1b after inspection enters between the guide rails 85 and 86 of the distribution means 45, and then the drive roller 88 is stopped to move the game board 1. Is stopped, the drive motor 92 is operated, and the rotating plates 83, 84 are turned 90 degrees around the longitudinal axes 80, 81 through the gears 90, 91, and the guide rails 85, 86 are moved to the guide rails on the side of the defective article conveying means 44. 7
Connect to 4,75. Then, the distributing means 45 and the driving roller 88 of the defective product transporting means 44 are rotated, and
The defective game board 1b between the guide rails 85 and 86 is transferred between the guide rails 74 and 75 on the defective product transport means 44 side and sent to the defective product transport means 44 side (step S11). The drive rollers on the side of the defective product transport means 44 are on the upper side and the lower side so as to exclude the repair work zone D, and the defective product game board 1b sent to the defective product transport means 44 side is a defective product. It is stocked in the repair work zone D of the transport means 44 (step S12). When several defective product gaming boards 1 accumulate on the upper side of the defective transporting means 44, the defective product gaming boards 1b on the lower side are sequentially repaired (step S13).

In the repair work zone D, when an operator presses a key on the display device 77, a defective product game board is displayed on the CRT.
Since the defective portion 1b is displayed, the operator checks the indication of the abnormal portion displayed on the CRT and repairs the defective portion of the defective game board 1 according to the instruction. For example,
If the fluctuating symbol display device 5 is defective, the game board 1 is pulled between the guide rails 78 and 79 of the turntable 76, and the turntable
After turning the 76 to turn the defective game board 1b face down and removing the lead wires and the like of the liquid crystal display device, the turntable is turned again to return the game board 1 to the front. Then, the variable symbol display device 5 including the liquid crystal display device is removed and replaced with another variable symbol display device 5.

In this case, since the game board 1 is on the turntable 76 and the defective game board 1b in the upright state can be easily inverted as it is, the repair work can be performed easily and efficiently. Game parts 37 for repair are on the parts shelf 38,
The parts shelf 38 is located between the repair work zone D and the assembling work zone A, and the gaming parts 37 can be taken from both sides of the repair work zone D and the assembling work zone A.
There is no need to separately prepare game parts 37 for assembly and repair, and the parts shelf 38 can be used for both assembly and repair. Can be used. Game board 1 after repair
Is transported from the lower side of the defective product transporting means 44 to the product transporting means 46 via the merging means 47 (steps S9 and S1).
0). The repair work in the repair work zone D is performed by one or more workers according to the number of defective game boards 1 generated.
