Abstract

In a sheet package, the degree of stiffness of a side end portion on a side wall portion side making contact with a contact member in a storage portion of a printing unit is greater than the degree of stiffness of a side end portion on the side wall portion side that is pressed by a pressing guide member. Accordingly, when the sheet package is stored in the storage portion, even if the lid body is closed in a condition in which the sheet package is not loaded properly, that is, even if the side end portion of the sheet package is sandwiched between the lid body and the contact member, or a top face on the side on which the contact member is provided, the sheet package is never crushed and the sheet package can be correctly pushed into the storage portion by a pressing force of the lid body.

a contact portion in the storage portion with which an end portion on one of two ends of the sheet package in a width direction of the sheet that is perpendicular to the direction of a sheet discharged from the sheet package makes contact;
a pressing portion that presses an end portion on a side of the sheet package that is different from the end portion on the one of the two ends in such a way as to press the end portion of the one side of the sheet package against the contact portion;
and
a lid supported in such a way that it is capable of being opened/closed as it covers the storage portion,
wherein a degree of stiffness of the end portion on the one side that is brought into contact with the contact portion is greater than a degree of stiffness of the end portion on the other side that is pressed by the pressing portion.
