PROBLEM TO BE SOLVED: To provide an operation button by which a user can easily recognize that it is a 2-step switch. SOLUTION: When a user applies a pressurizing force on a second pressurizing surface 241a, a second pressurizing button 240a is so pressed down that the second pressurizing surface 241a comes to be almost flush with a first pressuring surface 221a. A second protrusion 245a that protrudes from a rear surface 243a of the second pressurizing surface 241a pressurizes a second push switch 274. This action enables a camera to prepare for a photographing operation such as photometry action. Then, the user applies a force on the first pressurizing surface 221a. Since the end close to a hole 222a side of a first pressurizing button 220a is engaged with a movement regulating member 260a, the first pressurizing button 220a swings with the end as a support point. Then, the first protrusion 225a pressurizes a first push switch 272. The pressurized first push switch 272 transmits a signal to DSP, and a camera 100 controlled by the DSP performs the photographing operation. COPYRIGHT: (C)2009,JPO&INPIT |
