ABSTRACT:
A roll sheet supplying mechanism for a recording device is disclosed. The mechanism allows for a roll sheet to be rolled into a recording device in a simple and convenient manner. The mechanism is comprised of a shaft having tapered end. The shaft supports the roll sheet and is positioned such that one end can be inserted within a fixed receiving portion while another end can be received within a movable receiving portion. A roll sheet is positioned on the shaft and the shaft is positioned on a support member such that the ends of the shaft are in alignment with the fixed end portion and the movable end portion. The movable end portion is retracted and may be locked into an open retracted position. The movable end portion is then released and is forced towards a shaft end by a biasing member. When the movable receiving portion contacts the tapered end of the shaft the shaft end is forced into the movable receiving end portion and consequently forces the other tapered end of the shaft into the fixed end receiving portion.
