Claim:
A digital multifunction peripheral that has a fingerprint reader capability, comprising: an image scanner; and a processor portion that controls the digital multifunction peripheral including the image scanner; wherein the image scanner further includes: a scanner main body having a document glass on which a document to be scanned is placed; a scanner cover provided above the document glass of the scanner main body; a finger insert portion provided on the scanner cover; a sensor that detects a finger inserted in the finger insert portion; a carriage, on which a light source and a photoelectric converter portion are mounted, provided so as to be movable inside the scanner main body; a carriage moving mechanism provided inside the scanner main body to move the carriage to a position of the finger insert portion along the document glass surface; an image processing portion that extracts personal identification information from a read image of the scanner; a display portion that displays the duration of time from when the user inserts his finger in the finger insert portion until the carriage of the scanner starts image reading of the finger insert portion; and a time set portion that sets as desired the duration of time from when the sensor detects the finger until the carriage of the scanner reaches a fingerprint read position, the time set portion including a first timer to set the duration of time from when the sensor detects the finger until the carriage reaches the fingerprint read position, and a second timer to set the duration of time from when the sensor detects the finger until a command to start reading the fingerprint is issued to the carriage, wherein: let T 1 and T 2 be times set in the first timer and the second timer, respectively, and T be a time needed for the carriage of the scanner to reach the finger insert portion from a standby position, then the times establish a relation substantially expressed by an equation: T 1 −T 2 =T.
