[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an information processing apparatus capable of recording and / or reproducing a plurality of types of discs, and more particularly to an information processing device that shortens the processing time for disc determination.
[0002]
[Prior art]
A conventional information processing apparatus capable of recording and / or reproducing a plurality of types of discs includes a determination unit for automatically determining a loaded disc.
[0003]
FIG. 6 shows the flow of disk determination processing by the conventional determination means.
That is, when a disc is loaded into the apparatus main body, the determination means first determines whether or not the loaded disc is a CD (step S41). As a result, when the loaded disc is a CD (when it is determined Yes in step S41), information that a CD is loaded on the drive side is stored (step S42), and a command waiting state is entered. (Step S45).
[0004]
On the other hand, as a result of the determination, if the loaded disc is not a CD (if No is determined in step S41), it is next determined whether or not the loaded disc is a DVD (step S43). As a result, when the loaded disc is a DVD (when it is determined Yes in step S43), information that a DVD is loaded on the drive side is stored (step S44), and a command waiting state is entered. (Step S45).
[0005]
On the other hand, as a result of the determination, if the loaded disc is not a DVD (when it is determined No in step S43), an error process is performed because the disc cannot be determined (step S46).
[0006]
As described above, in the conventional disc determination process, discs are determined in a predetermined order. Therefore, when the loaded disc is a DVD, there is a problem that the determination process in step S41 becomes useless time, and a considerable waiting time is generated until DVD playback. This is the same when a CD is loaded when the flow of determination processing is DVD determination first and then CD determination. As described above, the conventional disc determination process has a problem in that the disc determination order is determined in advance.
[0007]
On the other hand, as one method for solving such a problem, two sets of a CD pickup unit and a CD signal processing circuit, a DVD pickup unit and a DVD signal processing circuit are mounted, and the CD signal processing circuit and the DVD signal are mounted. There has been proposed an optical pickup device having a configuration in which a circuit switching switch for switching between processing circuits is provided at a corner of a disk mounting surface of a drawer (tray) (see, for example, Patent Document 1).
[0008]
According to this optical pickup device, when a CD is placed in the drawer, the circuit changeover switch is switched to the CD side while the drawer is pulled out from the main body of the device, thereby shifting to the CD playback mode and loading the DVD in the drawer. When loading, switching the circuit switching switch to the DVD side with the drawer pulled out from the device main body shifts to the DVD playback mode, so that the disc determination process is omitted and the subsequent playback operation is performed quickly. Is possible.
[0009]

Japanese Patent Laid-Open No. 10-91992
[Problems to be solved by the invention]
However, in the apparatus of the above-mentioned patent publication 1, since it is necessary to mount two sets of signal processing systems of a CD pickup unit and a CD signal processing circuit and a DVD pickup unit and a DVD signal processing circuit, the apparatus becomes large. At the same time, there is a problem that the cost becomes expensive.
[0011]
Also, for example, if a CD is loaded but the circuit switch is accidentally switched to the DVD side and the drawer is loaded in the main body of the apparatus, it cannot be reproduced as it is. The user has to pull out the drawer again from the apparatus main body and switch the circuit switching switch to the CD side, which requires troublesome operations.
[0012]
The present invention was devised to solve such problems. The purpose of the present invention is to shorten the disc determination time by the user instructing the type of the disc to be loaded, and to specify the instruction from the user and the loaded disc. It is an object of the present invention to provide an information processing apparatus capable of automatically disc discriminating and starting a reproducing operation or a recording operation even when the type differs.
[0013]
[Means for Solving the Problems]
An information processing apparatus according to the present invention includes a determination unit that automatically determines the type of a loaded disc, and an eject that performs a pull-in operation of the disc placed on the tray into the device main body and a pull-out operation from the device main body. in the recording and / or reproducing an information processing apparatus capable of a plurality of types of disks and a switch, before SL during drawing operation of the disc by the operation of the ejection switch, automatic determination mode by pressing once the eject switch, 2 An input means for inputting an instruction signal for instructing the CD priority mode when it is continuously pressed and a DVD priority mode when it is continuously pressed to the determination means, and the type of mode instructed based on the instruction signal is displayed. and display means for said determination means, the starting point of the pull-in operation of the disc by the operation of the eject switch Start the disk determination processing, performs preferentially disc determined at the indicated mode according to the instruction signal 2 consecutive press or 3 consecutive press inputted, the once when the result of the determination is specified differently It is configured to perform an automatic determination mode similar to that in the case of pressing. In the CD priority mode, a disc type is determined by executing a playback process as if a CD is loaded, and in the DVD priority mode, It is characterized in that the disc type is determined by executing a reproduction process assuming that a DVD is loaded . Thus, even when the user mistakenly designates the type of the loaded disc, the automatic determination mode is finally executed, so that the loaded disc can be reliably determined.
[0017]

Although not shown, the system controller 10 stores a determination processing program for executing a disk determination process, which is a feature of the present invention, in an internal memory (ROM or the like).
[0022]
FIG. 2 shows an external view of the information processing apparatus configured as described above.
A drawer port 24 for a tray 23 is provided in the operation panel 22 on the front surface of the apparatus main body 21. Further, a volume switch 25 is provided on the left side of the lower part of the outlet 24, and a changeover switch 26 and an eject switch 27 are provided on the right side.
[0023]
FIG. 3 is an explanatory diagram in which the portion of the changeover switch 26 is enlarged.
The changeover switch 26 can be switched to one of three types of modes: a CD priority mode, a DVD priority mode, and an automatic determination mode. FIG. 6A shows a state in which the changeover switch 26 is switched to the automatic determination mode. In this automatic determination mode, as in the conventional processing, the CD or DVD is automatically determined based on the reflectance of light. Perform type determination. FIG. 5B shows a state in which the changeover switch 26 is switched to the CD priority mode. In this CD priority mode, the automatic determination process performed so far is skipped and a CD is inserted. As a result, the CD processing can be executed. FIG. 4C shows a state in which the changeover switch 26 is switched to the DVD priority mode. In this DVD priority mode, the automatic determination process performed so far is skipped and a DVD is inserted. As a result, DVD processing can be executed. However, if the user mistakenly sets the CD priority mode shown in FIG. 2 (b) and the DVD priority mode shown in FIG. 2 (c), information cannot be read from the disc. Judgment mode is executed.
[0024]
Next, in the information processing apparatus configured as described above, a disk determination process when the user loads the optical disk 1 into the apparatus main body will be described with reference to the flowchart shown in FIG.
[0025]
Before placing the optical disk 1 on the tray 23 pulled out from the apparatus main body 21 and loading it into the apparatus main body 1, the user switches the changeover switch 26 to instruct the type of the loaded optical disk 1 (step S1). Based on this instruction signal, the system controller 10 determines the type of the loaded optical disk 1 (step S2).
[0026]
As a result, when the changeover switch 26 is in the CD priority mode position and the instruction signal indicates the CD priority mode, the automatic determination process performed so far is skipped, and the information that the CD is inserted is stored in the internal information. (Step S3). Then, it is confirmed whether or not reading or writing is possible according to the stored information (step S4). If it is determined that it is possible, the CD processing can be executed (step S5), and a command waiting state is entered. Transition is made (step S10). On the other hand, when it is determined that reading or writing is impossible, the automatic determination process is executed as usual (step S9).
[0027]
On the other hand, if the result of determination in step S2 is that the changeover switch 26 is in the DVD priority mode position and the instruction signal indicates the DVD priority mode, the automatic determination processing that has been performed so far is skipped and the DVD is inserted. The information that it has been stored is stored inside (step S6). Then, it is confirmed whether or not reading or writing is possible according to the stored information (step S7). If it is determined that it is possible, the DVD processing can be executed (step S8), and a command waiting state is entered. Transition is made (step S10). On the other hand, when it is determined that reading or writing is impossible, the automatic determination process is executed as usual (step S9).
[0028]
If the result of determination in step S2 is that the changeover switch 26 is in the automatic determination mode position and the instruction signal indicates the automatic determination mode, automatic determination processing is executed as before (step S10).
[0029]
As described above , according to the information processing apparatus having the above-described configuration, when the CD priority mode or the DVD priority mode is designated by the changeover switch 26, the conventional automatic determination mode is not performed, and reading or writing is immediately performed. Since it can be made possible, the processing time for disc determination can be shortened.
[0030]
[Embodiment 1 ]
The information processing apparatus according to the first embodiment has a configuration in which the changeover switch 26 is deleted from the operation panel unit 22 of the apparatus main body 21 and the eject switch 27 is also used as the changeover switch 26 in the information processing apparatus having the above configuration. It is a thing.
[0031]
Specifically, during the pull-in operation of the tray 23 on which the optical disk 1 is placed, any one of three modes of the CD priority mode, the DVD priority mode, and the automatic determination mode is selected depending on the number of times the eject switch 27 is continuously pressed. It is what you specify.
[0032]
For example, when the eject switch is pressed once, an automatic determination mode is output, and when it is pressed twice continuously, a CD priority mode is output, and when it is pressed continuously three times, an instruction signal is output to the system controller 10. Is.
[0033]
Next, in the information processing apparatus configured as described above, a disk determination process when the user loads the optical disk 1 into the apparatus main body will be described with reference to the flowchart shown in FIG. However, here, a case where the disk determination process is performed during the disk pull-in operation will be described.
[0034]
The user pushes the eject switch 27 and pulls out the tray 23 from the apparatus main body 21. In this case, the system controller 10 confirms the position of the tray 23 by a tray detection sensor or the like (not shown), and confirms that the operation of the eject switch 27 is a disk pulling operation. In this case, the disk controller performs a disk determination process. Only the operation of pulling out the tray 23 is executed. At this point, the system controller 10 recognizes that the next time the eject switch 27 is operated, the operation is to pull the tray 23 and the mode is to execute the disc determination process. Further, the system controller 10 next monitors whether or not the eject switch 27 has been pressed (step S21).
[0035]
Thereafter, when the user places the desired optical disk 1 on the pulled-out tray 23 and operates the eject switch 27 to pull the tray 23 into the apparatus main body 21 (when it is determined Yes in step S21), The system controller 10 confirms whether or not the switch operation is a disk pull-in operation (step S22). In this case, since it is a disk pull-in operation, the system controller 10 performs a pull-in operation of the tray 23 into the apparatus main body 1 (step S23), and activates a disk determination processing program at this point in time to perform disk determination processing. Is started (step S24).
[0036]
That is, the system controller 10 confirms how many times the eject switch 27 has been pressed (step S25 to step S27). As a result, when the eject switch 27 is pressed once (when it is determined Yes in step S25), automatic determination processing is executed as usual (step S28), and thereafter, a transition is made to a command waiting state (step S28). S29).
[0037]
On the other hand, if the eject switch 27 is continuously pressed twice (No in step S25, Yes in step S26), it is determined that the CD priority mode is set, and the automatic determination performed so far is performed. The processing is skipped, and the information that the CD is inserted is stored inside (step S30). Then, it is confirmed whether or not reading or writing is possible according to the stored information (step S31). If it is determined that it is possible (when determined Yes), the CD processing can be executed (step S32). ), A transition is made to a command waiting state (step S29). On the other hand, when it is determined that reading or writing is impossible (when it is determined No in step S31), automatic determination processing is executed as usual (step S28).
[0038]
On the other hand, if the eject switch 27 is continuously pressed three times (No in step S25, No in step S26, Yes in step S27), it is determined that the DVD priority mode is selected, and so far. The automatic determination process that has been performed is skipped, and the information that the DVD is inserted is stored inside (step S33). Then, it is confirmed whether or not reading or writing is possible according to the stored information (step S34). If it is determined that it is possible (when determined Yes), the DVD processing can be executed (step S35). ), A transition is made to a command waiting state (step S29). On the other hand, if it is determined that reading or writing is impossible (No in step S34), automatic determination processing is executed as usual (step S28).
[0039]
In step S22, if the operation of the eject switch 27 is not a disk pull-in operation, other processing (specifically, a disk pull-out operation) corresponding to the switch operation is performed (step S36). In the above processing operation, the automatic determination process of step S28 is also performed when it is determined in step S27 that the eject switch 27 has been pressed three times or more. In this case, error processing or the like is performed. Also good.
[0040]
As described above, according to the information processing apparatus of the first embodiment, when the CD priority mode or the DVD priority mode is designated by the number of times the eject switch 27 is pressed during the disk pull-in operation, the conventional automatic determination process is performed. Since it is possible to immediately read or write without performing this, the processing time for disc determination can be shortened.
[0041]
In the first embodiment, the disk determination process based on the number of times the eject switch 27 is pressed is performed during the disk pulling operation, but may be performed during the disk pulling operation.
[0042]
In the first embodiment, the automatic determination mode, the CD priority mode, and the DVD priority mode are simply distinguished by the number of times the eject switch 27 is pressed. However, the present invention is not limited to this. For example, the normal one-time pressing may be set as the automatic determination mode, the long pressing (for example, 1 second or more) once may be set as the CD priority mode, and the long pressing twice may be set as the DVD priority mode. In this case, the number of times the eject switch 27 is pressed when the mode is designated can be reduced. In addition to this, various ways of pressing the eject switch 27 for distinguishing each mode can be devised, and mode determination based on how to push the eject switch 27 is performed by the system controller 10 side. Can be processed automatically.
[0043]
Furthermore, when a mode is specified by pressing the eject switch 27 as described above, a display unit such as an LED is provided on the operation panel unit 22 in order to clarify which mode is specified. For example, the mode specified by the user may be notified by turning off in the automatic determination mode, turning on in the CD priority mode, and blinking in the DVD priority mode.
【The invention's effect】
According to the information processing apparatus of the present invention, the operation panel unit of the apparatus main body is provided with the instruction means for the user to instruct the type of the disk to be loaded. Therefore, the time required for the conventional disc determination process can be shortened.
