Image recording apparatus for monitoring unauthorized copy jobs

摘要

An image recording apparatus includes a controller configured to: determine whether a change of a signal from a sensor indicates a case where a recording medium is conveyed by a conveyance mechanism or a case where the recording medium is placed on a placement unit without conveying by the conveyance mechanism, based on whether the recording medium is conveyed by the conveyance mechanism; start, when the reading unit is operated to start reading the image within a first predetermined time after the signal from the sensor is changed, monitoring to determine whether the recording medium is placed on the placement unit without conveying by the conveyance mechanism; and store, when it is determined during the monitoring that the recording medium is placed on the placement unit without conveying by the conveyance mechanism, data indicating an irregularity reading in the storage unit.

1. An image recording apparatus comprising:
a reading unit configured to read an image formed on a recording medium; a recording unit configured to record an image on the recording medium positioned in a recording area; a placement unit, on which the recording medium having the image recorded by the recording unit is placed; a conveyance mechanism configured to convey the recording medium to the placement unit via the recording area; a sensor configured to output a signal, based on whether the recording medium on the placement unit is detected; a storage unit; and a controller configured to control the reading unit, the recording unit, the conveyance mechanism, the sensor and the storage unit, wherein the controller is configured to: determine, when the signal received from the sensor is changed from a signal indicating that the recording medium is not detected to a signal indicating that the recording medium is detected, whether the change indicates a case where the recording medium is conveyed by the conveyance mechanism and is thus placed on the placement unit or a case where the recording medium is placed on the placement unit without conveying by the conveyance mechanism, based on whether the recording medium is conveyed by the conveyance mechanism; start, when the reading unit is operated to start reading the image within a first predetermined time after the signal received from the sensor is changed from the signal indicating that the recording medium is detected to the signal indicating that the recording medium is not detected, monitoring to determine whether the recording medium is placed on the placement unit without conveying by the conveyance mechanism; and store, when it is determined during the monitoring that the recording medium is placed on the placement unit without conveying by the conveyance mechanism, data indicating an irregularity reading in the storage unit.
