Title:
FILM UNIT WITH LENS
Document Type and Number:
Japanese Patent JP3723257
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To keep operating physical force necessary for the operation of a film wind knob low even though a film unit with a lens is thinned, and to improve the operability of the film wind knob.
SOLUTION: The film wind knob 26 for winding photographic film 21 is pivotally attached to the peripheral part 25a of an aperture 25. The peripheral part 25a is formed to be deviated toward a back cover from the rotary shaft (a) of a spool 22 piercing an aperture 25, and the rotary shaft (b) of the knob 26 pivotally attached to the peripheral part 25a is deviated toward the back cover from the rotary shaft (a) of the spool 22. A driving shaft 26a where external teeth 26b are engraved is integrally provided on the lower surface of the knob 26. The outside diameter of the driving shaft 26a is formed to be considerably smaller than the inside diameter of the shaft hole 22a of the spool 22, and a part of the external teeth 26b of the driving shaft 26a is meshed with the internal teeth 22b of the shaft hole 22a in a state where their rotary shafts are deviated each other.
