A cartridge has a surface to be biased which is connected to a first surface extending in an intersecting direction that intersects with an insertion direction from an upstream side to a downstream side in the insertion direction, and an engaging portion engaging with a support member that supports the cartridge inside a main body and has a biasing member that biases an engaged portion to be engaged with the engaging portion in the intersecting direction. The engaged portion has a biasing surface extending in the intersecting direction from the upstream side to the downstream side in the insertion direction. Movement of the support member in the intersecting direction by the closing operation of an opening and closing member, the surface to be biased is biased by the biasing surface, the cartridge contacts with a positioning portion, and positioning of the cartridge is performed.
