Patent ID: 8070157

Claim:
A recording apparatus comprising: a stacking section on which a recording target medium is stacked; edge guides which move in a width direction of the recording target medium and align side edges of the recording target medium which is stacked on the stacking section; a motor which moves the edge guides; a determining section which determines whether an electric current value at the time when the motor is driven reaches a predetermined threshold value; and a position detecting section which detects a position of the edge guides in the width direction, wherein when the side edges of the recording target medium are aligned, the edge guides move close to the recording target medium by means of power of the motor while the electric current value is being monitored by the determining section, and it is determined whether a difference between a position of the edge guides at the time when the electric current value reaches the predetermined threshold value and a position of the edge guides corresponding to the size of the recording target medium which is recognized on the basis of recording information by the recording apparatus is equal to or smaller than a predetermined allowable value, and wherein if it is determined that the difference is not equal to or smaller than the predetermined allowable value, the edge guides move away from the recording target medium by means of the power of the motor, and then, the edge guides move close to the recording target medium until the electric current value reaches the predetermined threshold value while the electric current value is being monitored.
