In recent years, high-frequency heating devices such as microwave ovens have become increasingly complex due to the expansion of cooking stoves and demands for effective use of space. That is, in addition to the high-frequency heating function, there are now composite food heating devices that incorporate multiple heating functions such as an open function, a grill function, and a steam function into one device.

In addition to being able to use each function independently, such a composite food heating device can also use high-frequency heating and other functions simultaneously or alternately, in which case it can shorten heating time and save energy. In addition to this, it also has the characteristic that it can sometimes make the taste of the food even better.

However, in this way, several types of functions can be used individually or in combination.

Operations such as selecting and setting the heating function are more complicated than ever before.
Since it may be difficult to associate the heating function with the object to be heated, the user is confused and the usability is considerably deteriorated.

3 P So, for example, the cooking device itself is equipped with a key arrangement that is operated by a perforated card, and the appropriate key is operated by the perforated card depending on the type of cooking.

2. Description of the Related Art Cooking devices that simplify the operation process by selecting a heating function, setting a heating time, and setting a heating temperature are becoming popular.

However, as the number of keys to be operated increases, depending on how the card holder is pressed, some keys may not be pressed sufficiently, and there is a risk that the cooker will start cooking without the above-mentioned key keys being insufficiently pressed. was there.
