In order to display the number of drives in this way, it is necessary to store the number of drives in memory, but it is common for electrical appliances such as washing machines and dryers to be turned off when they are finished with use. At that time, a capacitor is connected that is charged while power is supplied, so that the contents stored in the memory will not be erased. Therefore, if it is desired to reset the count value in the memory, the charge in the capacitor is discharged and the voltage at the power supply terminal of the memory is set to 0 to r.

(c) Problem to be solved by the invention If it is possible to display the count value of the number of times the electrical equipment is driven every time a consumable part of the electrical equipment is replaced, it will be possible to increase the durability of the replaced consumable parts. Is there a
Also, it is easy to use because you can tell at a glance when to replace it.

Therefore, in the conventional example described above, it is sufficient to discharge the capacitor in order to change the count value, but in order to do so, a discharge circuit and a switch for activating or disabling the discharge circuit are added to the capacitor. The count value must be reset by operating the switch. However, to prevent this switch from being tampered with, it is usually installed in a place that is not wanted to be touched by people, such as on the control board. Therefore, when you want to use it, it takes a lot of time and effort to remove the exterior, and it is not easy to use.
