Description

TECHNICAL FIELD The present invention relates to a card-type electric device that drives an electric device such as a washing machine or a dryer using a card.

(B) Conventional technology This kind of electric equipment is disclosed in Japanese Utility Model Publication No. 63-27678. This one discloses that the number of times the washing machine is driven is counted and the count value is displayed on the number display of the operation panel.

In order to display the number of times of driving as described above, it is necessary to store the number of times of driving in the memory, but in an electric device such as a washing machine or a dryer, it is common to turn off the power when finished using it. At that time, a capacitor that is charged while power is being supplied is connected so that the contents stored in the memory are not erased. Therefore, if you want to reset the count value in the memory, discharge the electric charge of the capacitor and set the power supply terminal voltage of the memory to 0V.

(C) Problem to be Solved by the Invention Whenever a consumable part of an electric device is replaced, the count value of the number of times the electric device is driven is reset so that the number of times can be displayed. You can see at a glance if you have it or when you should replace it,
It is easy to use.

Therefore, in the above-mentioned conventional example, the capacitor may be discharged in order to change the count value, but for that purpose, a discharge circuit and a switch for operating or not operating the discharge circuit are added to the capacitor, and The count value must be reset by operating the switch. However, this switch is usually provided in a place where it is not desired to be touched by a person because it does not want to be mischievous, for example, on a control board. Therefore, if the user intends to use the product, it is very troublesome to remove the outer casing, which is inconvenient.
