Image processing apparatus for accessing a storage medium on a sheet

An image processing apparatus comprising:

• a transport unit configured to transport a sheet;
• an access unit configured to access a storage medium attached to the sheet transported by the transport unit;
• and
• a controller configured to determine a length of an access time required for the access unit to complete access from a time when the access is started,
• wherein the controller is configured to control the transport unit to change a passing time during which the sheet attached with the storage medium passes an access range of the access unit, according to the length of the access time,
• wherein the image processing apparatus further comprises:
• a correction storage unit configured to store correction information which is used when the controller controls the transport unit to change the passing time, and
• wherein the controller is configured to, when access to the storage medium is not normally completed, update the correction information such that the passing time for a subsequent sheet increases.

An image processing apparatus comprising:

• a transport unit configured to transport a sheet;
• an access unit configured to access a storage medium attached to the sheet transported by the transport unit;
• a controller configured to determine a length of an access time required for the access unit to complete access from a time when the access is started;
• and
• wherein the controller is configured to control the transport unit to change a passing time during which the sheet attached with the storage medium passes an access range of the access unit, according to the length of the access time
• wherein the transport unit is capable of returning the sheet having passed through the access range of the access unit to the access range again, and
• wherein the controller controls the transport unit according to the number of times the sheet is to be passed through the access range of the access unit.
