When the switch SW7 is pressed, a series circuit of a pull-up resistor r2 and a resistor R6 is formed. As a result, the voltage VL2 between the line L2 and ground is Vcc, and the resistance of the pull-up resistor r6 Assuming that the value is r6 and the resistance value of the resistor R6 is also R6, VL2 = Vcc {R6 / (r2 + R6)}.

  When the switch SW8 is pressed, a series circuit of a pull-up resistor r2, a resistor R6, and a resistor R7 is formed. As a result, the voltage VL2 between the line L2 and the ground is the power supply voltage Vcc, and the pull-up resistor If the resistance value of r2 is also r2, the resistance value of resistor R6 is R6, and the resistance value of resistor R7 is R7, then VL2 = Vcc {(R6 + R7) / (r2 + R6 + R7)}.

  When the switch SW9 is pressed, a series circuit of a pull-up resistor r2, a resistor R6, a resistor R7, and a resistor R8 is formed. As a result, the voltage VL2 between the line L2 and the ground becomes the power supply voltage Vcc, If the resistance value of the up resistor r2 is also r2, the resistance value of the resistor R6 is R6, the resistance value of the resistor R7 is R7, and the resistance value of the resistor R8 is R8, then VL2 = Vcc {(R6 + R7 + R8) / (r2 + R6 + R7 + R8) )}become.

  When the switch SW10 is pressed, a series circuit of a pull-up resistor r2, a resistor R6, a resistor R7, a resistor R8, and a resistor R9 is formed. As a result, the voltage VL2 between the line L2 and the ground changes the power supply voltage to Vcc. When the resistance value of the pull-up resistor r2 is also r2, the resistance value of the resistor R6 is R6, the resistance value of the resistor R7 is R7, the resistance value of the resistor R8 is R8, and the resistance value of the resistor R9 is R9. VL2 = Vcc {(R6 + R7 + R8 + R9) / (r2 + R6 + R7 + R8 + R9)}.

  An AV (Audio Visual) substrate 2 receives an audio signal and a video signal from a tuner or an external input terminal (not shown) and performs predetermined audio signal processing and video signal processing, and controls the AV circuit 21. A sub-side microcomputer 22 is mounted as a sub-process control unit that performs control and processing related to test mode activation, which is a feature of the present embodiment. Although there are other components of the AV board 2, they are omitted here. The sub-side microcomputer 22 operates even when it is powered off when AC power is supplied to the optical disk device. Since the sub-side microcomputer 22 is not a flash type whose function can be changed, once it is manufactured, the function etc. cannot be changed, and it is common to enter the test mode for the optical disc apparatus of each manufacturer. It is desirable to adopt an activation method.

  The sub-side microcomputer 22 includes an A / D (analog / digital) conversion unit 23 that converts a voltage from the output terminal T1 of the switch substrate 1 into a digital value, and a digital switch from the A / D conversion unit 23 for the pressed switch.

When the detecting means 26 detects that the AC power is turned on in the pressed state, the pressed switch discriminating means 24 The test mode corresponding to the pressed switch is read from the table 25, set in the optical disk apparatus, and has test mode starting means 27 for starting the optical disk apparatus as the test mode, with one or more switches pressed. The optical disk apparatus is activated as a test mode in response to the AC power supply to the optical disk apparatus being turned on.

  The main board 3 is mounted with a decoder circuit 31 that inputs audio signals and video signals from the AV board 2 and performs decoding processing, and a main microcomputer 32 that performs main data processing and control of the apparatus. Yes. Although there are other constituent elements of the main board 3, they are omitted here. The main-side microcomputer 32 normally does not operate unless it is powered on operatively. However, when it is set to a constant power-on mode, which will be described later, the main-side microcomputer 32 operates even if it is operatively powered off.

  FIG. 2 is a view showing an example of the contents of a table showing the relationship between the push switch and the test mode when the AC power is turned on to the optical disc apparatus in a state where any switch on the switch board is pushed in the present embodiment. It is.

  In FIG. 2, a table 25 is provided in the sub-side microcomputer 22. According to Table 25, when the push switch is the switch SW9 (FWD key), the test mode always corresponds to the power-on mode, and when the push switch is the switch SW4 (CH / UP key) and the switch SW8 (STOP key), The test mode corresponds to forced F company remote control mode. When the push switch is the switch SW2 (CH / DOWN key) and the switch SW7 (PLAY key), the test mode corresponds to the AV board operation inspection mode, and the push switch is the switch SW3 (REC / SPEED key) and the switch SW10 ( When the REV key is selected, the test mode corresponds to the clock fast-forward mode.

  FIG. 3 is a flowchart for explaining test mode activation processing in the present embodiment. The test mode activation process will be described with reference to this flowchart and FIGS.

  First, insert the power plug of the optical disk device into an AC outlet and turn on the AC power to the optical disk device, or provide a power on / off switch between the AC outlet and the power plug of the optical disk device. When the AC power source is turned on by the power-on means such as turning on the AC power source and turning on the optical disk device (step S1), the sub-side microcomputer 22 is activated by releasing the reset (step S1). S2). When the sub-side microcomputer 22 is activated, the voltage (the voltage of the line L1 and the voltage of the line L2) from the output terminal T1 of the switch board 1 is received by the input terminal T2 of the AV board 2 via the connector C, and A / D The digital value is converted by the conversion means 23 (step S3).

  Next, the sub-side microcomputer 22 discriminates the push switch by the push switch discriminating means 24, but none of the switches SW1 to SW10 of the switch board 1 may be pushed. If the digital value from the A / D conversion means 23 when not pressed is detected, it is determined that there is no push switch (step S4), thereby starting the optical disk apparatus in the normal mode (step S10). The normal mode process is performed (step S11), and when the normal mode process ends (step S12), the process ends.

  When any one of the switches SW1 to SW10 on the switch board 1 is pressed, the push switch discriminating unit 24 outputs from the A / D conversion unit 23 when any one of the switches SW1 to SW10 is pressed. By detecting the digital value, it is determined that there is a push switch (step S4). Here, the switch-pressed state power-on detection means 26 detects that the AC power to the optical disc apparatus has been turned on while one or more switches are pressed. Further, the push switch discriminating unit 24 discriminates the pressed switch by referring to the digital value from the A / D conversion unit 23 (step S5).

  Next, the test mode starting unit 27 stores a test mode corresponding to the press switch determined by the press switch determining unit 24 when the switch pressed state power on detecting unit 26 detects that the AC power is turned on in the switch pressed state. 25 and set in the optical disk device (step S6), the optical disk device is activated as a test mode (step S7), a test mode process is performed (step S8), and the test mode process is completed (step S9). This processing is finished.

  For example, as the test mode, when the switch SW9 (FWD key) is pressed and AC power is turned on to the optical disk apparatus, the optical disk apparatus is always set to the power-on mode, and the software of the main microcomputer 32 is Used for debugging. The power-on mode is always turned off if the operation is turned off, the main board 3 is turned off, and the software development debugger is also down. The power is turned on inside the apparatus.

  Further, when the switch SW4 (CH / UP key) and the switch SW8 (STOP key) are pressed and the AC power is turned on to the optical disk apparatus, the forced F company remote control mode is set. Can be operated with the remote control. When the switch SW2 (CH / DOWN key) and the switch SW7 (PLAY key) are pressed and the AC power is turned on to the optical disk apparatus, the AV board operation inspection mode is set and the operation of the AV board 2 is performed. Can be inspected. As an inspection of the operation of the AV board 2, the main board 3 is not connected and, for example, the AV board 2 alone is used to check whether all segments of the display lamp are normally lit, and whether the tuner relationship is normal. There are inspections.

  Further, when the AC power is turned on to the optical disc apparatus with the switch SW3 (REC / SPEED key) and the switch SW10 (REV key) pressed, the clock fast-forward mode is set, for example, 10 minutes after timer reservation. For example, when the operation is performed after 20 minutes, it is not possible to wait for 10 minutes or 20 minutes in the operation test. For example, when the switch SW9 (FWD key) is pressed, the time can be advanced quickly.

  As described above, according to the present embodiment, in order to activate a desired test mode, when a predetermined switch is pressed and AC power is supplied to the optical disc apparatus in this depressed state, the desired test mode is activated. This eliminates the need to activate the test mode by pressing a dedicated test key on the remote control or combining and pressing multiple keys on the remote control as in the past. This eliminates the loss of time and makes it possible to start the test mode simply and quickly. As a result, the time required for testing the optical disc apparatus can be shortened, and the production cost can be reduced.
