[0001]

[Industrial application]

 The present invention relates to a simple tester for checking the power supply voltage of an indoor wiring outlet into which a plug of a pachinko machine is inserted.

[0002]

[Prior Art]

 FIG. 5 is a front view showing a state in which a large number of pachinko machines are installed on the island stand. A large number of pachinko machines 90 are installed on the island stand 92, and a large number of outlets (not shown) are installed on the island stand 92 on the back side of the pachinko machine 90. These outlets have a mixture of 24V AC and 100V AC. This is because the power of the pachinko machine 90 is AC 24V while the power of the abnormality display lamp 94 above the island stand 92 is AC 100V. The structure of the above-mentioned outlet is exactly the same for both AC 24V and AC 100V.

[Problems to be solved by the device]

 By the way, a piece of paper with "24V" written on it was stuck to the plug of a pachinko machine, but it often happens that the plug is accidentally inserted into a 100V outlet. If you insert the plug of the pachinko machine into an outlet of 100V, the fuse inside the pachinko machine will be blown and the IC etc. mounted on the printed wiring board will be destroyed, so you must replace the fuse and the printed wiring board. Will disappear. In addition, to measure the outlet voltage with a general electric tester, you need to set the AC voltage, which is one of the many measurement functions, and measure with the two probes plugged into the outlet. Therefore, if you do not have some electrical knowledge, you will not be able to measure the correct voltage.For example, if you use the current measurement function to melt the fuse of the electrical tester, you may short the two probes. This could cause an accident such as operating the safety breaker and causing a temporary power failure. Furthermore, the measurement with the electric tester requires both hands to hold the electric tester while inserting the two probes into the container with one hand, which is a very troublesome work. The present invention has been devised in view of such circumstances, and a simple power supply for a pachinko machine that can easily prevent anyone from damaging the pachinko machine by mistakenly inserting the plug into a 100V outlet. The purpose is to provide a tester (hereinafter simply referred to as "tester").

[0007]

[Action]

 The operation of the tester according to claim 1 is as follows. Insert the plug into the power outlet with one hand. When the power source is 100 V AC, the high voltage notification unit operates. When the power supply is 24V AC, the high voltage notification unit does not operate.

The operation of the tester according to claim 2 is as follows. Insert the plug into the power outlet with one hand. When the power source is AC 100V, the normal voltage notification unit does not operate. When the power supply is 24V AC, the normal voltage notification unit operates.

The operation of the tester according to claim 3 is as follows. Insert the plug into the power outlet with one hand. When the power supply is 24V AC, the relay does not operate and the contacts remain closed. Therefore, the alternating voltage 24V is applied to the notification member, and the notification member operates. When the power supply is 100V AC, the relay operates and the contacts open. Therefore, the AC voltage of 100 V is not applied to the notification member, and the notification member does not operate.
