PURPOSE: To enable the appropriate handling of a film and the secure cooling thereof after the use by providing a housing with a shaft extended in the longitudinal direction of the housing while riding over a filter housing unit, and providing a constraining member for surrounding the shaft with a notch provided in a grip of a filter and for fixing the grip of the filter. CONSTITUTION: A shaft 28 is arranged between two side walls of a holder connected to a housing 2 in both sides of a filter housing unit, and a second shaft 29 is arranged between the side walls. When a filter 22 is positioned at an outward rocking position, the second shaft 29 is surrounded by other cutout of a grip 23 of the filter, and furthermore, a lock piece 30 capable of being vibrated around the second shaft 29 and for surrounding a side wall of the holder like a fork-shape is provided as a constraining member. With this structure, handling of the filter 22 is facilitated, and the operation of a shutter is not hindered, and the rocking of the filter outward and inward of the housing part thereof can be performed remarkably accurately. |
