Film transfer apparatus and a film transfer roller used therein |
摘要 |
A film transfer apparatus includes an apparatus casing having a feed-core support shaft for detachably mounting a feed core and a take-up core support shaft for detachably mounting a take-up core. The support shafts respectively include a transmission member for causing the feed core to provide a film ribbon take-up speed higher than a ribbon feed speed of the feed core. For slippably coupling the feed core rotation and the take-up core rotation, a slip coupling mechanism is provided. This mechanism is constituted by an engaged portion of the take-up core for engagement with a mating engaging portion of the take-up core support shaft. The engaged portion is elastically deformable to a non-transmission condition with application thereto of a force exceeding a predetermined level. Further, the engaged portion is provided with a mechanical strength smaller than the engaging portion.
