Printer with housing for rolled paper

A printer comprising:

• a case comprising an input port from which a rolled paper is put into a housing that houses the rolled paper;
• a cover provided to be rotatable between a closed position that closes the input port and an open position that opens the input port;
• a holding portion that is rotatably attached to the case, extends toward the input port, and holds the rolled paper;
• a biasing member that biases the holding portion in a first direction toward the rolled paper housed in the housing;
• a stopper mechanism provided in the cover and the holding portion that stops rotation of the holding portion in the first direction;
• and
• a linkage mechanism that rotates the holding portion in conjunction with the rotation of the cover when the cover rotates from the closed position to the open position,
• wherein, when the cover is in the closed position, the holding portion rotates in the first direction in accordance with an outer diameter of the rolled paper by a biasing force of the biasing member,
• wherein, when the cover rotates from the closed position to the open position, the holding portion rotates together with the cover against the biasing force of the biasing member,
• wherein the stopper mechanism controls the rotation of the holding portion in the first direction within a predetermined rotation range, and moves the cover and the holding portion together when the cover rotates from the closed position to the open position.
