IMAGE READING APPARATUS

摘要

An image reading apparatus includes a reading portion that reads an image on a target object; a motor that cause the reading portion to move; and a control portion that controls the reading portion and the motor. Further, in a case where the motor does not enter a step-out state, the control portion executes a first reading operation that causes the reading portion to read the image simultaneously with causing the motor to cause the reading portion to move at a high speed, and in a case where the motor enters the step-out state, the control portion executes a second reading operation that causes the reading portion to read the image simultaneously with causing the motor to cause the reading portion to move at a low speed, and generates image data having a resolution lower than a high resolution corresponding to the low speed.

主权项

1. An image reading apparatus comprising:
a reading portion that reads an image on a target object; a driving source that cause the reading portion to move; and a control portion that controls the reading portion and the driving source, wherein, in a case where the driving source does not enter a step-out state, the control portion executes a first reading operation that causes the reading portion to read the image simultaneously with causing the driving source to cause the reading portion to move at a first movement speed, and in a case where the driving source enters the step-out state, the control portion executes a second reading operation that causes the reading portion to read the image simultaneously with causing the driving source to cause the reading portion to move at a second movement speed lower than the first movement speed, and generates image data having a resolution lower than a resolution corresponding to the second movement speed.
