The power saving control unit 2 reads the correspondence table from the ROM provided in the power saving control unit 2 (step S31). The power saving control unit 2 determines whether or not the changeover switch 3 is in the on state (step S32). When it is determined that the changeover switch 3 is in the on state (YES in step S32), the power saving control unit 2 displays the invalid function notification screen for a predetermined time (step S33) and turns off the main power switch 12 (step S34). . The power saving control unit 2 sets the first power saving state in which all the sub power switches 10 are turned off based on the correspondence table (step S35), and ends the power switch process.

  In step S <b> 32 for determining whether or not the changeover switch 3 is in the on state, the power saving control unit 2 determines that the changeover switch 3 is not in the on state (NO in step 32). It is determined whether or not (step S36). When the power saving control unit 2 determines that the power switch 1 is turned on (YES in step S36), the power saving control unit 2 sets a normal operation state in which all the sub power switches 10 are turned on based on the correspondence table (step S37).

When the power saving control unit 2 detects a recording start signal output from the recording reservation circuit 9, the power saving control unit 2 executes a recording reservation process. The power saving control unit 2 turns on the main power switch 12 (step S41). The power saving control unit 2 reads the correspondence table from the ROM included in the power saving control unit 2 (step S42), and the sub power switch other than the sub power switch 10f is turned off among the sub power switches 10 based on the correspondence table. A second power saving state in which the supply of power to the peripheral circuits except 16 is stopped is set (step S43). The power saving control unit 2 causes the recording circuit 18 to start recording (step S44). The power saving control unit 2 determines whether or not the recording circuit 18 has finished recording (step S45). If the power saving control unit 2 determines that the recording is not finished (NO in step S45), the power saving control unit 2 stands by until the recording is finished.

  When the power saving control unit 2 determines that the recording is finished (YES in step S45), the main power switch 12 is turned off (step S46), and it is determined whether the changeover switch 3 is in the on state (step S47). ). When it is determined that the changeover switch 3 is in the on state (YES in step S47), the power saving control unit 2 sets the first power saving state in which all the sub power switches 10 are turned off based on the correspondence table (step S48). Then, the recording reservation process is terminated. When the power saving control unit 2 determines that the changeover switch 3 is not in the ON state (NO in step S47), only the sub power switch 10c is turned off based on the correspondence table, and the supply of power only to the lighting circuit 7 is stopped. The standby state is set (step S49), and the recording reservation process is terminated.

  The quick start circuit 13 performs quick start by rotating the disk recording medium at a predetermined speed and calibrating the signal circuit and the optical circuit even when the power supply to the recording circuit 18 is stopped. Although an example of enabling is shown, the present invention is not limited to this, and the video acquisition circuit 17 may select and decode. In other words, the quick start circuit 13 continues the operation for a peripheral circuit that takes a long time from the start of power supply until it becomes operable, even if the power supply is stopped. Anything that makes it possible. The correspondence table shown in FIG. 3 shows a case where all the sub power switches 10 are turned off in the first power saving state. However, the present invention is not limited to this, and the sub power switch connected to at least one peripheral circuit is turned off. A power saving state in which power consumption is reduced as compared with the standby state may be set.

  The change-over switch 3 has been shown in the case where the first switch position and the second switch position correspond to the on state and the off state, respectively, but is not limited thereto, and may be configured to correspond to the off state and the on state, respectively. Good. Although an example in which power is supplied to the activation circuit 5 according to the correspondence table shown in FIG. 3 when the main power switch 12 is turned on by an on operation of the power switch 1 or a recording start signal is shown, the present invention is not limited to this. Rather, since it is not necessary to turn on the main power switch 12 by the activation circuit 5, a correspondence table is set so that the supply of power to the activation circuit 5 is stopped and stored in the ROM included in the power saving control unit 2. May be. Although an example in which power is supplied to the quick start circuit 13 according to the correspondence table shown in FIG. 3 when the changeover switch 3 is turned off is shown, the present invention is not limited to this, and the user can enable or disable the quick start. If the quick start is set to be invalid, the correspondence table may be changed so that the power supply to the quick start circuit 13 is stopped. In this case, the power saving control unit 2 may be configured to read the correspondence table stored in the ROM to the RAM and perform power saving control, and rewrite and change the correspondence table read to the RAM.

  In the recording device, when the changeover switch 3 is turned on by the user while the recording circuit 18 is recording, the example of setting the first power saving state after waiting for the end of the recording is shown, but the present invention is not limited to this. In the case where the recording circuit 18 is performing a dubbing operation for reproducing the recorded video and outputting it to another recording device connected to the outside, the first power saving state is set after waiting for the end of the dubbing operation. May be. Although an example in which the recording apparatus always outputs the broadcast signal from the output terminal 19 has been shown, the output of the broadcast signal may be stopped in the first power saving state and the second power saving state.

Embodiment 2
FIG. 10 is a schematic diagram illustrating an example of a detailed setting screen (selection screen) according to the second embodiment. In the second embodiment, the on / off state of the sub power switch 10 is set based on the correspondence table previously stored in the ROM provided in the power saving control unit 2 in the first embodiment. The sub power switch 10 to be turned off in the power saving state can be selected. The power saving control unit 2 reads the correspondence table stored in the ROM provided in the power saving control unit 2 to the RAM provided in the power saving control unit 2 and performs power saving control. When the remote operation signal indicates an operation for performing detailed setting of the changeover switch 3, the power saving control unit 2 generates a changeover switch detailed setting screen, outputs it from the output terminal 19, and displays it on an external display device. In the example of the changeover switch detailed setting screen shown in FIG. 10, the title “eco-mode detailed setting” indicating that it is a detailed setting screen related to the changeover switch 3 and the function to be turned off in the power saving state are displayed. The indicator is displayed.

When the user operates a cursor key provided in the remote control device or the reception unit 4, the cursor moves each indicator, and the indicator at the cursor position is selected and highlighted by operating the setting key. It is. In addition, a bulleted message explaining a function that is disabled when power supply is stopped is displayed. The power saving control unit 2 has a function corresponding to the selected indicator when the user operates a determination key included in the remote operation device or the reception unit 4 and receives a remote operation signal or an identification signal indicating the operation.
