[0038]
Next, the operation will be described.
FIG. 2 is a flowchart showing the selector automatic switching process A executed by the CPU 11a of the recording / reproducing apparatus 1. Hereinafter, the selector automatic switching processing A will be described with reference to FIG.
[0039]
When the MD mode is selected by operating the mode switching key, the selector 15 is switched to the MD side (step S1; YES), and a request for turning on the Net MD mode is input by operating the operation unit 12 (step S2; YES), the CPU 11a sets the operation mode to the Net MD mode (step S3) and switches the selector 15 to the USB side (step S4).
[0040]
After the selector 15 is switched to the USB side, a request for turning off the MD MD mode is not input by the operation unit 12 (step S5; NO), and an MD playback request command is input from the PC 2 via the USB 3 (step S6). YES), the CPU 11a switches the selector 15 to the MD side (step S7) and controls each part of the MD recording / reproducing unit 14 to reproduce the music data recorded on the MD and output it from the speaker 18 (step S8). ). When an MD playback stop command is input from the PC 2 (step S9; YES), the CPU 11a sets a built-in timer and starts measuring time (step S10), and waits for a time-up signal from the timer (step S11). ). If an MD playback request command is input from the PC 2 during this time (step S12; YES), the CPU 11a returns to step S8 and repeatedly executes steps S8 to S12. When the time-up signal from the timer is input (step S11; YES), the CPU 11a returns to step S4, switches the selector 15 to the USB side, and executes the processing after step S4.
[0041]
On the other hand, after the selector 15 is switched to the USB side in step S4, if a request for turning off the NetMD mode is input (step S5; YES), the CPU 11a sets the Net MD mode to OFF (step S13), and the selector 15 Is switched to the MD side (step S14).
[0042]
According to the selector automatic switching process A described above, when the operation mode is set to the Net MD mode by the operation of the operation unit 12, the CPU 11a automatically switches the selector 15 to the USB side. As a result, the music data of the PC 2 can be output to the speaker 18, so that the music data recorded on the hard disk 24 or the CD drive 25 of the PC 2 can be reproduced and output. On the other hand, if the selector 15 is on the USB side, music data from the MD cannot be output from the speaker 18. Therefore, when the MD playback request command is input from the PC 2, the CPU 11a automatically switches the selector 15 to the MD side. When an MD playback stop command is input from the PC 2, the CPU 11a automatically switches the selector 15 to the USB side. Here, depending on the application program of the PC 2, when one piece of MD is played back, it stops and may be played back. After the MD has stopped, the selector 15 is switched to the USB side after a predetermined time has passed in the stopped state.
[0043]
Therefore, the user does not need to perform mode switching operations in the recording / playback apparatus 1 each time when playing back music data, checking out to MD, playing back MD, etc. according to the recording / playback application program of the PC 2, and operability. And convenience is improved.
[0044]
Next, the selector automatic switching process B executed by the CPU 11a will be described with reference to the flowchart of FIG.
[0045]
When the MD mode is selected by operating the mode switching key, the selector 15 is switched to the MD side (step S21; YES), and a request for turning on the Net MD mode is input by operating the operation unit 12 (step S22; YES), the CPU 11a sets the operation mode to the Net MD mode (step S23).
[0046]
After setting to the Net MD mode, when a power OFF request is input from the power ON / OFF key of the operation unit 12 (step S24; YES), the CPU 11a determines whether or not the selector 15 has selected the MD side. (Step S25) When it is determined that the selector 15 has not selected the MD side (Step S25; NO), the selector 15 is switched to the MD side (Step S26), and the power OFF process is executed (Step S27). On the other hand, when the selector 15 determines that the MD side is selected (step S25; YES), the CPU 11a executes the power-off process as it is (step S27).
[0047]
According to the selector automatic switching process B described above, when a power OFF request is input from the power ON / OFF key of the operation unit 12 in the Net MD mode, the CPU 11a determines whether or not the selector 15 has selected the MD side. If it is determined that it is not on the MD side, the selector 15 is switched to the MD side and then the power OFF process is executed.
[0048]
Therefore, by executing the selector automatic switching process A described above, even if the user turns off the power when the state of the selector 15 is changed from the state at the start of the Net MD mode, the power is turned on next. At this time, since the selector 15 stands up in a state similar to the state at the start of the Net MD mode (MD side), there is no possibility that the user is uncomfortable by the automatic switching of the selector 15.
[0049]
Next, the selector backup process executed by the CPU 11a will be described with reference to the flowchart of FIG.
[0050]
When the MD mode is selected by operating the mode switching key, the selector 15 is switched to the MD side (step S31; YES), and a request for turning on the Net MD mode is input by operating the operation unit 12 (step S32; YES), the CPU 11a sets the operation mode to the Net MD mode (step S33).
[0051]
After switching to the Net MD mode, when the CPU 11a detects that the power plug of the recording / reproducing apparatus 1 has been unplugged from the AC outlet when the signal from the AC power supply becomes a Low signal (step S34; YES), the selector 15 It is determined whether or not the MD side is selected (step S35), and if the selector 15 determines that the MD side is not selected (step S35; NO), the contents of the selector backup RAM in the RAM 11c are rewritten to MD (step S35). S36), a backup process is executed (step S37). On the other hand, if the selector 15 determines that the MD side is selected (step S35; YES), the CPU 11a executes the backup process without rewriting the backup RAM (step S37).
[0052]
According to the selector backup process described above, when the CPU 11a detects the Low signal from the AC power supply, the CPU 11a determines whether or not the selector 15 selects the MD side. Execute backup processing after rewriting.
[0053]
Therefore, even if the user unplugs the plug from the AC outlet while the selector 15 has changed from the state at the start of the Net MD mode by executing the selector automatic switching processing A described above, When the power is turned on after being inserted into the outlet, the selector 15 stands up in a state similar to the state at the start of the Net MD mode (MD side), so that the automatic switching of the selector 15 gives the user a sense of incongruity. Disappears.
[0054]
In the present embodiment, the recording / reproducing apparatus 1 is configured to connect the plug to the AC outlet. However, the method for connecting to the power source is not limited to this, and for example, a DC outlet may be used.
[0055]
Next, the selector status display process executed by the CPU 11a will be described with reference to the flowchart of FIG.
[0056]
When the MD mode is selected by operating the mode switching key, the selector 15 is switched to the MD side (step S41; YES), and a request for turning on the Net MD mode is input by operating the operation unit 12 (step S42; YES), the CPU 11a sets the operation mode to the Net MD mode (step S43).
[0057]
After setting to the Net MD mode, the CPU 11a determines whether or not the selector 15 has selected the MD side (step S44), and determines that the selector 15 is in the MD side (step S44; YES). The display panel unit 13 displays that the selector 15 is on the MD side (step S45), and if the selector 15 is determined not to be on the MD side (step S44; YES), the selector 15 is connected to the display panel unit 13 with the USB. Is displayed (step S46). Until the NetMD mode OFF request is input (step S47; NO), the CPU 11a repeatedly executes steps S44 to S47.
[0058]
According to the selector state display process described above, when the Net MD mode is set, the CPU 11a determines whether or not the selector 15 is in a state where the MD side is selected. 13 displays that the state of the selector 15 is the MD side, and if it is determined that the state is not the MD side, the display unit 13 displays that the state of the selector 15 is the USB side. Therefore, the user can know the state of the selector 15 in the Net MD mode.
[0059]
As described above, by executing the above-described selector automatic switching processing A, B, selector backup processing, and selector status display processing by the CPU 11a, MD music data without the user performing mode switching operation in the Net MD mode. The music data input from the PC 2 can be reproduced. Further, the user can grasp the state of the selector 15. Further, even when the power is turned off or the AC outlet is pulled out in the Net MD mode, the state of the selector 15 can be returned to the state at the start of the Net MD mode when the recording / reproducing apparatus 1 is started up. The switching process can be performed without giving
