Title:
SHEET FILM PACK
Document Type and Number:
Japanese Patent JP2003149771
Kind Code:
A
Abstract:

To prevent the light leakage from a counter housing chamber of a sheet film pack into a pack body.

A counter display plate 21 of a circular shape is freely rotationally movably dropped into a box-like counter housing chamber 20 formed at the end of the pack body 3 and a pressing plate 22 having a spring section 22a is guided and disposed in a guide groove 20a of the counter housing chamber 20 from above the same and further, a shielding plate 24 for shielding the light of a pull cap side aperture 30b of the counter housing chamber 20 is put and fixed from above the same. Even if external light enters the inside of the counter housing chamber 20 from a feed pawl accepting aperture, the arrival of this external light at the sheet film in the pack body 3 is blocked by the shielding plate 24. The spring end 22b of the pressing plate 22 is regulated by the inner wall surface of the shielding plate 24 and does not directly push up the pull cap and therefore the clearance between the sliding contact surface of the pack body and the pull cap can be prevented from being increased.
