Title:
FILM UNIT WITH LENS
Document Type and Number:
Japanese Patent JPH1165032
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To prevent resale after improperly refilling a film. SOLUTION: In this unit body, a mark 45('F' in this case) that designates the name of a manufacturer or a sales company is formed on the front surface of a shutter blade 34 so that the magnified mark 45 can be seen from the outside of the unit body through the lens 9 when the shutter blade is at the closed position and hence, reuseing the unit body as it is can be prevented. If the mark 45 is shaved off, an excessive gap between the shutter blade 34 and a blade retainer 33a is produced, whereby play is produced so that it may happen that a picture taking opening 37 can not be shaded from the light or a recessed part formed on the back of the shutter blade 34 is penetrated and hence, a light leak occurs; thereby, it is prevented that a unit body which is recomposed by refilling a new photograph film cartridge in the original unit body misappropriated as it is unfairly sold.
