Image recording apparatus including judging portion for judging whether image has been already recorded onto medium

摘要

An image recording apparatus includes: a tray for holding a medium; a conveying portion for conveying the tray; a recording portion for recording an image onto the medium held by the tray; a detecting portion for detecting the medium. A detection-region determining portion determines, a detection region of the medium which is to be detected and a detection-region memory portion memorizes the determined detection region. Prior to the next image recording, the detecting portion detects the detection region, based on the detection region that has been memorized in previous image recording. A judging portion judges whether the image has been already recorded onto the medium or not, based on result of detection made by the detecting portion.

主权项

1. An image recording apparatus comprising:
a tray configured to hold a disk; a conveying portion configured to convey said tray in a conveyance direction that is perpendicular to a main scanning direction; a recording portion configured to print an image onto the disk that is held by said tray; a detecting portion movable in the main scanning direction and configured to detect the disk and said tray; a detection-region determining portion configured to determine, based on the image printed in a recorded region of the disk, a detection region of the disk having at least a part of the image printed therein, the detection region being to be detected by said detecting portion, the detection region including at least a part of the recorded region; a detection-region memory portion configured to memorize a position of the detection region that has been determined by said detection-region determining portion; a controlling portion configured to cause, prior to a next printing of the image onto a disk that is held by said tray, moving said detecting portion to said detection region, by controlling said conveying portion and said detecting portion, based on the position of the detection region that has been memorized in said detection-region memory portion in previous printing of the image; and a judging portion configured to judge whether the image has been already printed onto the disk or not, based on a result of a detection of the at least a part of the image made by said detecting portion at said detection region.
