An endoscope apparatus includes a first optical system, a second optical system, a light-blocking shutter 35, a magnet rotor, drive coils 44 and 45, detection coils 41 and 42, and a CPU 80, the CPU 80 performs control to provide direct current to the drive coils 44 and 45 and control to provide alternating current to the detection coils 41 and 42, and where the alternating current is provided to the detection coils 41 and 42, the CPU 80 detects a pivotal position of the light-blocking shutter 35 by detecting variation of an inductance when a magnetic field generated in each of hollow portions of the detection coils 41 and 42 is blocked by a magnetic body, from a value of the alternating current. |
