Title:
BUFFER MEMBER OF CAMERA SHUTTER
Document Type and Number:
Japanese Patent JP2014126810
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an inexpensive buffer member of a camera shutter that sufficiently absorbs the impact of a drive lever driving a shutter blade.SOLUTION: A buffer member (120) contains an upper surface (121) facing a drive lever (112), and in the upper surface (121), a square pyramidal-shape projection part (122) is provided. The square pyramidal-shape projection part (122) includes an apex (123). Consequently, the buffer member (120) starts contacting with the drive lever (112) from the apex (123). Namely, the buffer member (120) starts contacting with the drive lever (112) locally. Then, as the rotation of the drive lever (112) progresses, the buffer member is deformed and its contact area gradually becomes larger. As the result, the impact transmitted to the drive lever (112) can be sufficiently absorbed.
