  • Patent number: 5704135
    Abstract: An instant photographic print drying device. The device has a stand which carries a fan and a heating coil. Downstream of the fan the photograph is held in place by clips. A timer is provided which can be set to a prescribed time to dry the photographs. An on/off switch is provided and a momentary switch is optionally present to provide a little more drying time, without resetting the timer. A thermostat might be included to prevent overheating of the coils, and possible overheating and burning of the photograph. Optionally, the clips holding the photograph in place can be connected to a micro-switch, which activates the timer controlling the fan and heating coil when a photograph is placed on the stand.
