<1-3. About the configuration of the function section>

  Here, the relationship of each functional unit for the DVD recorder 1 according to the first embodiment to perform the opening process of the present invention will be described with reference to the block diagram of FIG. In addition, the broken-line arrow line in FIG. 1 has shown the flow of the control signal.

  As shown in FIG. 1, the opening process of the present invention is performed by a code receiving unit 11a, an operation monitoring unit 11b, an opening / closing control unit 11c, and a setting unit 11d included in the control unit 11.

  The code receiving unit 11a receives a radio signal using infrared rays or the like from the remote controller 100, and analyzes a remote control code included in the radio signal. Then, a control instruction based on the analysis result is given to each unit, for example, the operation monitoring unit 11b. As a result, various processes based on user operations performed on the remote controller 100 are performed.

  The operation monitoring unit 11b monitors whether a predetermined operation is detected by the operation unit 13. The operation monitoring unit 11b monitors whether a predetermined remote control code is detected by the code receiving unit 11a. For example, it is monitored whether or not an operation for shifting the DVD recorder 1 from a power stop to an activated state or a remote control code including an instruction to reproduce recorded data is detected.

  Further, the operation monitoring unit 11b determines the type of operation detected and the operation indicated by the remote control code. The operation monitoring unit 11b classifies the operation type into two types. Specifically, a first operation that is effective regardless of the state of the optical disk mounted on the optical disk drive 106, and a second operation that is effective only when the optical disk is in the optical disk drive 106 (= general purpose). Operation).

  As the first operation, for example, a power start / stop operation (= power control operation) by the power button 101, a setup menu call operation or a recording reservation operation (= setting operation) by the function button group 102, or a mode switching operation (= function) The selection operation) corresponds to this. Examples of the second operation include a playback start / stop operation and a dubbing operation using the normal button group 103.

  The open / close control unit 11c is configured to detect the disc tray when the second operation is detected by the operation monitoring unit 11b when the disc tray of the optical disc drive 16 is closed and no optical disc is mounted on the disc tray. The optical disk drive 16 is controlled to perform the opening operation.

  The setting unit 11d receives settings related to various processes performed by the control unit 11 from the user. For example, a selection instruction for switching on / off the operation of the opening / closing control unit 11c is received. When the operation of the opening / closing controller 11c is designated as OFF, the disc tray opening operation is not performed even if the second operation is detected. The setting information indicating the setting contents is recorded in the flash memory 14 or the HDD 15.

  Specifically, the setting unit 11d controls the OSD processing unit 19 so as to generate, for example, an image signal for displaying the setting screen 200 illustrated in FIG. Then, the generated image signal is output to the display 2 via the external connection terminal 21. Thereby, the setting screen 200 is displayed on the display 2.

  As shown in FIG. 4, the setting screen 200 includes a message window 201 and a cursor 202. The user can select the “Yes” button or the “No” button included in the message window 201 by moving the cursor 202 using the operation unit 13 or the remote controller 100.

When a determination button (not shown) included in the operation unit 13 is pressed while the cursor 202 is positioned on the “Yes” button, the setting unit 11d performs opening / closing control so as to perform an opening process described below. Instruct the unit 11c.
<1-4. About opening process>

  Here, the opening process of the present invention performed by the DVD recorder 1 according to the first embodiment will be described with reference to the flowchart of FIG. In the process shown in FIG. 5, it is detected that the power source of the DVD recorder 1 is activated, the disc tray of the optical disc drive 16 is closed, and no optical disc is mounted on the disc tray. Start at the point.

  After the start of this process, the operation monitoring unit 11b determines whether a user operation by the operation unit 13 or the remote controller 100 is detected in step S110. If no user operation has been detected, the process proceeds to step S110 again to continue monitoring.

  When a user operation is detected, the operation monitoring unit 11b analyzes the received operation content in step S120. Specifically, for example, the type of the remote control code received by the code receiving unit 11a is determined. Based on the analysis result, the button pressed by the user is determined.

  Next, in step S130, the operation monitoring unit 11b branches the process depending on whether the pressed button is the power button. The power button is a button for switching ON / OFF of the main power supply of the DVD recorder 1, and corresponds to the power button 101 provided on the remote controller 100 and the button provided on the housing of the DVD recorder 1.

  If the pressed button is the power button, the operation monitoring unit 11b shifts the DVD recorder 1 to the power stop state in step S131, and then ends this process. If the pressed button is not the power button, the operation monitoring unit 11b branches the process in step S140 depending on whether or not the pressed button is a predetermined function button.

  The predetermined function button is a button for performing an operation that is effective regardless of the state of mounting of the optical disk on the disk tray, and corresponds to the button for performing the first operation described above.

  If the predetermined function button has been pressed, the operation monitoring unit 11b executes a process corresponding to the pressed function button in step S141, and then ends this process. For example, when the setup button is pressed, the system shifts to the setup state. Alternatively, when the transition button to the HDD mode is detected, the mode shifts to the HDD mode in which recording / reproduction by the HDD 15 is performed.

  If the pressed button is not the predetermined function button, the opening / closing control unit 11c controls the optical disc drive 16 to open the disc tray in step S150, and then ends this processing. As a result, the user can mount the optical disc on the optical disc drive 16.

  In step S150, the process corresponding to the button detected to be pressed is not performed. For example, even if the pressed button is an optical disc playback stop button, a playback stop processing command is not issued. As a result, this user operation is invalidated.

According to the present embodiment described above, when an operation that is effective only when the optical disc is not mounted on the disc tray and the optical disc is mounted is detected, regardless of the received operation instruction, Open the disc tray. This eliminates the need for the user to search for and press the open button on the disc tray, thereby reducing the operating procedure and improving operability.
