An organic electroluminescence device 1 includes: an anode 3, a cathode 4 opposed to the anode 3 and an emitting layer 5 provided between the anode 3 and the cathode 4. Due to a spur gear being rotated clockwise by a motor, a sliding cover, with which the spur gear is engaging, is moved toward a removing portion such that an opening of a cassette stocker portion is opened. A mirror is moveably positioned between the image side of at least one lens and the image sensor.
