专利汇可以提供Manual stopping-down device of single-lens reflex camera专利检索，专利查询，专利分析的服务。并且PURPOSE: To enable stopping-down state to be maintained as desired at any point before and after photographing irrespective of whether the shutter has been charged or not by enabling the iris to be maintained in the stopped-down state or opened as desired simply through pushing-down operation of a push-button.
CONSTITUTION: The aperture preset member of a photographing lens 30 having an aperture lever 29 and drive mechanisms 1, 2, etc. are connected by means of a spring 14 so that in the aperture automatic reset state where the iris is maintained at full open only the aperture preset member may be moved from the initial position corresponding to the aperture full open up to aperture value independently irrespective of the drive mechanisms. When an interlocking member interlocking to the pushing-down of a push-button 10 is provided and when the push button 10 is pushded once, the interlocking member is moved to move the aperture preset membr to the stopping-down position and be maintained there. When the push button is pushed once more, the interlocking member is reset to reset the aperture preset member to the initial position.
