1. A medium conveying apparatus comprising:
a motor in which a setting of a torque can be changed according to a supplied power;
a medium tray provided on a housing and to be raised, and including a placing surface;
a roller to abut on a medium placed on the medium tray to convey the medium; and
a processor to
control the motor so that the medium tray is located at a position at which the medium placed on the medium tray abuts on the roller, each time a particular number of media placed on the medium tray is conveyed, and
detect a position of the placing surface, wherein
the processor sets the torque of the motor to a first torque when the placing surface is in a first position, and sets the torque of the motor to a second torque smaller than the first torque when the placing surface is in a second position above the first position, and wherein
a gap between the housing where the medium tray is provided and the medium tray is exposed to an outside of the medium conveying apparatus, during conveying the medium.
