Image recording apparatus in which a recorded content or output for which the confidentiality is required can be prevented from being visible to another user

An image recording apparatus, comprising:

• a recording device configured to perform recording of an image on a recording medium;
• a plurality of discharge trays to which is discharged the recording medium on which the image has been recorded by the recording device, each of the plurality of discharge trays configured to enable the discharged recording medium on which the image has been recorded to be freely removed;
• a discharge mechanism configured to discharge, to any of the plurality of discharge trays, the recording medium on which the image has been recorded by the recording device;
• a plurality of detectors, each of which is provided for a corresponding one of the plurality of discharge trays for detecting presence and absence of the recording medium discharged on the corresponding one of the plurality of discharge trays;
• an input device through which is inputted authentication information in relation to image data which is transmitted from an exterior and based on which the image is recorded by the recording device;
• and
• a controller which is configured to control operations of the image recording apparatus and which includes:
• a reception portion configured to receive the image data;
• an authentication-information confirming portion configured to confirm whether or not the authentication information inputted through the input device contains specific information;
• a confirmation-necessity judging portion configured to judge, when the reception portion receives the image data, whether the confirmation by the authentication-information confirming portion with respect to the image data is necessary or not;
• a selecting portion configured to select, from among the plurality of discharge trays, one discharge tray on which the recording medium is not placed,
• wherein, when the confirmation-necessity judging portion judges that the confirmation by the authentication-information confirming portion with respect to the image data is necessary, the controller permits the selecting portion to select the one discharge tray, controls the recording device to record the image based on the image data after the authentication-information confirming portion has confirmed that the authentication information contains the specific information, and controls the discharge mechanism to discharge, to the one discharge tray selected by the selecting portion, the recording medium on which the image based on the image data has been recorded,
• wherein, when the confirmation-necessity judging portion judges that the confirmation by the authentication-information confirming portion with respect to the image data is not necessary, the controller controls the recording device to record the image based on the image data on the recording medium and controls the discharge mechanism to discharge, to any one of the discharge trays, the recording medium on which the image based on the image data has been recorded, and
• wherein the controller permits the selecting portion to stand by without conducting selection of one of the discharge trays until the selection by the selecting portion becomes possible, where the selection by the selecting portion is impossible when the confirmation-necessity judging portion judges that the confirmation by the authentication-information confirming portion with respect to the image data is necessary.
