<p>PROBLEM TO BE SOLVED: To prevent careless exposure state transfer of a content discharge port covered so as not to be exposed to an external space range of a shutter trigger mechanism.SOLUTION: When a shutter trigger mechanism is in an illustrated stationary mode, a slider 18 locks a stem joint 15 and a trigger lever 17. When sliding the slider 18 right, first, both an abutment state between a cam action part 17f and an arm-like action part 18d and an abutment state between a linear locked action part 17d and a linear lock action part 18m are released, and an abutment state between a cylindrical part lower end part of the stem joint 15 and an arc-shaped step part 18g is also released. By further slide operation, a trigger lever drive action part 18n depresses a lengthwise convex part 17e to expose a discharge port 15b. When performing pull operation of the trigger lever 17 in an exposure state thereof, the cam action part 17 drives a driven convex part 15d and a stem 14 integrated therewith downward, and a content is discharged from the discharge port 15b.</p> |
