Abstract
An electronic apparatus that performs switching with the use of a piezoelectric element comprises a piezoelectric element 11, a first monitor electrode 15, and a second monitor electrode 16, the latter two being provided thereon and intended to output electric shock signals that are generated when a shock has been applied to the piezoelectric element 11 to thereby distort it. Whereby, a shock is applied to the electronic apparatus that contains the piezoelectric element 11 and a shock is applied to the built-in piezoelectric element 11. This makes it possible to output for the purpose of controlling the operation of the respective functions an electronic shock signal that is generated when the piezoelectric element 11 is distorted. As a result, it is possible to reduce the number of switch parts for, and hence the size of, the electronic apparatus and reduce the amount of time and labor for performing the switching operation by utilizing the piezoelectric effect of the piezoelectric element.
