Abstract: A strobe device including, a strobe main body including a light emitting surface; a plate-like reflector provided on the strobe main body so as to be movable between a use position in which the reflector protrudes forward from the light emitting surface of the strobe main body and a storing position in which the reflector is retracted backward from the use position; a reflector magnetic member made of ferromagnetic material or permanent magnet and attached to the reflector; and a main body magnetic member made of ferromagnetic material or permanent magnet and attached to the strobe main body, wherein when the reflector approaches at least one of the use position and the storing position, the main body magnetic member magnetically attracts the reflector magnetic member and holds the reflector at the one of the use position and the storing position by magnetic attraction.

Abstract: To prevent a transformer such as a trigger transformer from becoming unable to perform transformation as designed due to short circuits caused by leakage of an insulating wax or the like even when the temperature of the transformer becomes high, a sealed chamber is formed in an outer bobbin which accommodates a secondary winding by a sealing member and the sealed chamber is filled with an insulating wax.

Abstract: A rotary operation switch including a support body, an operation member rotatably supported by the support body and a switch mechanism provided therebetween to define multiple positions in a rotational direction of the operation member, wherein one of the support body and the operation member defines multiple recesses corresponding to the multiple positions, and wherein the rotary operation switch includes: a movable engaging body formed of a permanent magnet or a magnetic material and provided on the other of the support body and the operation member to engage with or disengage from the recesses as the operation member is rotated; a guiding portion provided on the other of the support body and the operation member to guide the engaging body; and a magnetic attractive force generation portion provided on the one of the support body and the operation member to exert magnetic attractive force on the engaging body.
