Claim:
A medium transporting apparatus which is mounted on a recording apparatus main body for recording with respect to a medium to be recorded comprising: a transporting unit that is driven by a motor and transports the medium to be recorded in a transport direction; and a first transport path that has the transporting unit on a path and reverses the sides of the medium to be recorded when guiding the medium to be recorded which is transported by the transporting unit, wherein the first transport path is installed so as to be connected to the middle of a second transport path that guides the medium to be recorded between a mounting portion for mounting the medium to be recorded in the recording apparatus main body and a recording portion for recording with respect to the medium to be recorded, the medium transporting apparatus has a first mode in which after there has been recording on a first surface of a preceding medium to be recorded by the recording portion, according to the length of the medium to be recorded, in a state in which a first roller installed in the recording portion transports the preceding medium to be recorded in reverse to the upstream side in the transport direction at the time of recording and inserts it into the first transport path, and the transporting unit holds the preceding medium to be recorded, a second roller installed on the mounting portion transports a succeeding medium to be recorded to the recording portion side while guiding it to the second transport path, after there has been recording on a first surface of the succeeding medium to be recorded by the recording portion while the first roller transports the succeeding medium to be recorded, when the first roller transports the succeeding medium to be recorded in reverse to the upstream side in the transport direction at the time of recording and inserts it into the first transport path, the transporting unit retreats the preceding medium to be recorded, which is positioned in the first transport path, from a side which is opposite to the side where it was inserted into the first transport path, to the second transport path and transports it to the recording portion, after a second surface, which is a rear surface when there has been recording on the first surface of the preceding medium to be recorded is a front surface, by the recording portion, while the first roller transports the preceding medium to be recorded, when the first roller transports the preceding medium to be recorded to the downstream side in the transport direction at the time of recording, the transporting unit retreats the succeeding medium to be recorded, which is positioned in the first transport path, from the side which is opposite to the side where it was inserted into the first transport path, to the second transport path and transports it to the recording portion side.
