CONSTITUTION:When executing image pickup on print paper 46 whose length is L1, it is executed by use of a reflector 43 and an image pickup lens 11. In case of viewing a character, etc. on the blackboard, etc., a relay lens of a convex lens 33 is provided in the rear of the image pickup lens 11 on this optical axis, and on this convex lens 33, a focusing screen 28 for forming two focuses is provided. A picture on this focusing screen has size of L1, and can be viewed from an observation window 42 through a reflector 39. In this case, the length L1 of the image on the print paper 46 is reduced to length L2 on the focusing screen 28, therefore, the image seems to be bright. |
