A printer includes a fragment receiving section provided below a cutter and receiving a non-printing area cut off as a fragment falling thereinto, and a printed matter receiving section provided below the cutter and receiving a printing area cut off as a piece of printed matter and falling thereinto. The fragment receiving section includes a rocking plate rocked by a rocking mechanism between a first rocking position, where an upper end of the rocking plate resides on the downstream side in a paper conveying direction with respect to a cutting position so as to allow the fragment to fall into the fragment receiving section, and a second rocking position, where the upper end of the rocking plate resides on the upstream side in the paper conveying direction with respect to the cutting position so as to guide the piece of printed matter into the printed matter receiving section.
