２に記載の結露防止装置付カメラ。[Claims for Utility Model Registration] 1. A camera equipped with a lens barrier that is movable between a closed position that covers the photographic lens and an open position that does not cover the photographic lens, wherein the lens barrier is configured to heat the photographic lens. A camera with a dew condensation prevention device, comprising: a resistor installed on the lens barrier; and a control means for controlling energization of the resistor. 2. The lens barrier is provided with a driving device, and is driven to an open position by the driving device before photographing starts, and is returned to a closed position by the driving device when photographing ends. Camera with anti-condensation device. 3. Claim 1, wherein the control means starts timing in response to activation of a power switch and completion of photographing, continues counting for a predetermined period of time, and keeps the resistor in a heated state during the counting period. Or a camera with a dew condensation prevention device according to claim 2.
