Reading apparatus, method of controlling reading apparatus, and non-transitory computer-readable storage medium storing program causing computer to control reading apparatus to correct reading position of document

A reading apparatus, comprising:

• a transparent member;
• a frame surrounding the transparent member;
• a plate-shaped member arranged on the transparent member;
• a transporter including a pair of rollers and transporting a document such that the document is brought into contact with the transparent member in a first position in a transport direction of the document and the document is brought into contact with the plate-shaped member in a second position in the transport direction;
• image sensor that is provided with respect to the transparent member to be configured to move in a moving direction along the transport direction and that reads the document;
• and
• a controller controlling movement and reading operation of the image sensor, wherein
• the image sensor reads the document transported by the transporter in a third position between the first position and the second position in the moving direction, the third position in which the document is out of contact with the plate-shaped member and the transparent member,
• the controller identifies the third position in accordance with a position of the plate-shaped member detected by the image sensor, and
• when a number of the document transported by the transporter exceeds a predetermined number, the controller causes the image sensor to read the plate-shaped member and detects abrasion of the plate-shaped member in accordance with a detected position of the plate-shaped member.

• and
• a controller controlling movement and reading operation of the image sensor, wherein
• the image sensor reads the document transported by the transporter at a third position between a first position and a second position in the moving direction, while the transporter transports the document in the transport direction,
• the document is brought into contact with the transparent member at the first position and is brought into contact with the plate-shaped member at the second position, which is positioned upstream of the first position in the transport direction,
• the document is out of contact with the plate-shaped member and the transparent member at the third position,
• the controller identifies the third position based on the first position or the second position,
• the image sensor does not read the document at the second position, and
• when a number of documents transported by the transporter exceeds a predetermined number, the controller causes the image sensor to read the plate-shaped member and detects abrasion of the plate-shaped member in accordance with a detected position of the plate-shaped member.
