1. 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.
