Abstract: PURPOSE: To exert no influence on an output of an operational amplifier in a normal state, by providing a diode bridge connected to the operational amplifier, and opening a circuit so that an excessive input provided from the outside is not provided to the operational amplifier.  
     CONSTITUTION: An input of a terminal 5 is provided to an operational amplifier 1, and reaches a terminal 6 through a diode bridge 2 constituted of diodes D 1 ∼ D 4 .

In case when a current has flowed to the diode 2 from an output of the operational amplifier 1, the bridge scarcely exerts influence on the output of the operational amplifier 1. On the other hand, if an excessive input of plus is provided to the terminal 6, the diodes D 2 , D 3  cut this excessive input, therefore, the excessive input does not reach the amplifier 1 side. Since the excessive input is provided to the electric power source 4, however, a protecting circuit for cutting off the electric power source 4 only in this case is provided.

CONSTITUTION:To use a barrel sinking waist-level viewfinder, an outer barrel 3 is turned to the left to be moved up along an up-down groove. Then the barrel 3 is turned to the right at the position where an elastic member 14 hits a flange part 3a. Thus an eyepiece 8 is held between a frame 7 and a support plate 6 to be fixed and to be ready for use. In case no loupe is used, a loupe catch 9 is turned against an elastic member 10 to move down the loupe. Then a hooking member 12 is made to engage the loupe against the energizing force of an elastic member 13 to store the loupe. When the loupe is used, the catch 9 is turned in the direction where the energizing force of the member 10 is obtained to release the hooking state between the members 12 and 13. Thus the loupe can be used by the energizing force of the member 10.
