Reading apparatus and reading control method that reduces misalignment at a joint between a pixel read before a read-suspension event and a pixel read after the read-suspension event

A reading apparatus comprising:

• an image sensor;
• a movement mechanism including a motor configured to relatively move between a document and the image sensor;
• an encoder configured to detect information about the movement;
• and
• a control unit configured to control driving of the motor and reading by the image sensor based on detection by the encoder,
• wherein, when a read-suspension event occurs during the reading by the image sensor, the control unit performs control such that the reading is continued while decelerating the motor,
• a relative position of a last read pixel of the document with respect to a read position by the image sensor is monitored based on the detection by the encoder, and the driving of the motor is stopped when it is determined that the read position reaches a stop position set within the last read pixel, and
• after the stop, the motor is driven again in a same direction without being reversed, to resume the reading with a pixel next to the last read pixel.
