Abstract
A recording apparatus includes a recording unit which records image data to a recording medium or reproduces image data from the recording medium, and a control unit which enables a first control mode for controlling the recording unit in response to a request from an external device if the apparatus can communicate with the external device, and disables the first control mode and enables a second control mode for controlling the recording unit in response to a request from a user. If the first control mode is disabled and the second control mode is enabled, the control unit determines whether a state of the recording medium is changed. If the state of the recording medium is changed, the control unit controls the recording unit so as to read the recording medium.
Claims16
A recording apparatus comprising:
- a recording unit configured to record image data to a recording medium;
- and
- a control unit configured to (a) enable a first mode for controlling the recording unit in response to a request from an external device if the recording apparatus is connected with the external device, (b) determine that a state of the recording medium is changed if the request from the external device is received while the first mode is enabled, and (c) enable a second mode for controlling the recording unit in response to a request from a user if the recording apparatus is disconnected from the external device,
- wherein if the request from the external device is received while the first mode is enabled and the control unit determines that the state of the recording medium is changed, the control unit controls the recording unit to obtain recording medium information from the recording medium, the recording medium information including information relating to the recording medium, and
- wherein if the request from the external device is not received while the first mode is enabled and the control unit determines that the state of the recording medium is not changed, the control unit controls the recording unit not to obtain the recording medium information from the recording medium.
A method of controlling a recording apparatus including a recording unit configured to record image data to a recording medium, the method comprising:
- if the recording apparatus is connected with the external device, controlling the recording apparatus to enable a first mode for controlling the recording unit in response to a request from an external device;
- controlling the recording apparatus to determine that a state of the recording medium is changed if the request from the external device is received while the first mode is enabled;
- if the recording apparatus is disconnected from the external device, controlling the recording apparatus to enable a second mode for controlling the recording unit in response to a request from a user;
- if the request from the external device is received while the first mode is enabled and the recording apparatus determines that the state of the recording medium is changed, controlling the recording unit to obtain recording medium information from the recording medium, the recording medium information including information relating to the recording medium;
- and
- if the request from the external device is not received while the first mode is enabled and the recording apparatus determines that the state of the recording medium is not changed, controlling the recording unit not to obtain the recording medium information from the recording medium.
