Optical reader, control method of optical reader, and computer-readable recording medium that shortened first transport distance of medium

A control method of an optical reader including a transport section capable of transporting a medium which is a reading target in forward and backward directions along a transport path;

• and an optical reading section installed in the transporting path, the optical reading section that optically reads the medium which is transported by the transport section, the control method comprising:
• setting a transport direction of the medium at the time of reading of the medium on the basis of (1) a position of the medium before or when the reading of the medium is started and (2) a reading position of the optical reading section such, that a first transport distance of the medium until the reading of the medium is completed is shortened relative to a second transport distance until the reading of the medium is completed corresponding to a second transport direction different than the transport direction;
• and
• controlling the transport section and the optical reading section on the basis of the set transport direction.

A non-transitory computer-readable recording medium that stores a program which causes a control section that controls an optical reader including a transport section capable of transporting a medium which is a reading target in forward and backward directions along a transport path;

• and an optical reading section installed in the transporting path, the optical reading section that optically reads the medium which is transported by the transport section, to perform a control method comprising:
• setting a transport direction of the medium at the time of reading of the medium on the basis of (1) a position of the medium before or when the reading of the medium is started and (2) a reading position of the optical reading section, such that a first transport distance of the medium until the reading of the medium is completed is shortened relative to a second transport distance corresponding to a second transport direction different than the transport direction;
• controlling the transport section to transport the medium on the basis of the set transport direction;
• and
• controlling the optical reading section to optically read the medium on the basis of the set transport direction.
