TECHNICAL FIELD OF THE INVENTION
The present invention relates to an optical disk device that records a program based on recording reservation data stored in a main body.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a general optical disk device is provided with a tray drive unit for moving a tray for mounting an optical disk between an open state and a closed state. The open state is a state in which the tray protrudes from the main body. In this state, the optical disk mounted on the tray is taken out, and the optical disk set in the main body is mounted on the tray. The closed state is a state in which the tray is stored in the main body. In this state, data is recorded on the optical disk placed on the tray and data is read.
[0003]
By the way, since the tray in the open state protrudes from the main body as described above, if the user keeps holding this state, there is a high possibility that the user will hit or hit an object and be damaged. Therefore, a general optical disk device is configured such that when the main power of the main body is turned off, if the tray is in the open state, the tray is closed and the main power is turned off.
[0004]
The state in which the main power is off is a so-called standby mode, in which a control unit that controls the operation of the main body and a reception unit that receives a code transmitted from a remote control, for example, a code that requests that the main power is turned on. In this state, operating power is supplied to a part of the main body.
[0005]
Further, Patent Documents 1 and 2 disclose optical disc devices that close a tray when an open state of the tray continues for a certain period of time even when the main power is on. When the user forgets to turn off the main power, the optical disk device does not keep the open state of the tray forever, even if the tray is open, and the user hits or hits an object. Thus, the tray can be more reliably prevented from being damaged.
[0006]
There is also an optical disk device having a recording function of recording a television broadcast program on an optical disk such as a DVD or VCD set in the main body. An optical disc device having a recording function is provided with a recording reservation function. As is well known, the recording reservation function is a function of recording a program based on recording reservation data including a recording start time, a recording end time, a channel on which the program to be recorded is broadcast, and the like, which are input to the main body in advance. It is. The optical disk device is provided with a storage unit (memory) for storing the recording reservation data input to the main body.

[Problems to be solved by the invention]
However, the optical disk device having the recording reservation function is configured not to execute the recording based on the recording reservation data stored in the main body when the main power is on. The reason for this configuration is that the user stops using the main unit for another purpose, such as stopping the recording of a program that the user has reserved for recording for some reason and watching a program recorded on another optical disk. In this case, if the recording reservation is prioritized, use by the user is hindered.
[0009]
Therefore, if the user forgets to turn off the main power after inputting the recording reservation data, there is a problem that the recording based on the recording reservation data is not executed.
[0010]
SUMMARY OF THE INVENTION An object of the present invention is to provide an optical disc apparatus capable of suppressing a situation in which recording based on recording reservation data is not executed when a user forgets to turn off a main power supply without hindering use of the user. Is to do.
[0011]
[Means for Solving the Problems]
An optical disk device according to the present invention has the following configuration in order to solve the above problems.
[0012]
Tray driving means for moving the tray on which the optical disc is placed, between a closed state stored in the main body and an open state protruding from the main body,
Tray state detecting means for detecting whether the tray is open or closed,
Receiving means for receiving a broadcasted program;
Recording reservation data receiving means for receiving input of recording reservation data,
Recording reservation data storage means for storing the recording reservation data received by the recording reservation data receiving means,
Recording means for recording the program received by the receiving means on an optical disc mounted on the tray in the closed state, based on the recording reservation data stored in the recording reservation data storage means, With
When the main power supply of the main body is turned off, if the state of the tray is an open state, in the optical disc apparatus in which the tray driving means closes the tray,
The tray drive unit may be configured such that the tray state detection unit sets the tray state to the open state a predetermined time before the recording start time included in the recording reservation data stored in the recording reservation data storage unit. If is detected, move the tray to the closed state,
When the tray driving means moves the open tray to the closed state a predetermined time before the recording start time included in the recording reservation data stored in the recording reservation data storage means, an optical disk is stored in the tray. Is determined, and if an optical disk is mounted, it is determined whether or not recording of a program based on the recording reservation data is possible on the optical disk. A control means is provided for causing the recording means to execute recording of a program based on the recording reservation data when the judgment is made.
[0013]
In this configuration, when the tray driving unit turns off the main power, the tray is closed. Therefore, when the tray is open, the main power of the main body is on. If the tray is in the open state a predetermined time before the recording start time included in the recording reservation data stored in the recording reservation data storage unit, the tray driving unit moves the tray to the closed state. Thereafter, the control means determines whether or not the optical disk is placed on the tray moved to the closed state, and whether or not it is possible to record a program based on the recording reservation data on the placed optical disk. If possible, the recording means executes recording based on the recording reservation data.
[0014]
Therefore, even if the operation of turning off the main power supply of the main body and the operation of closing the tray after the optical disk for recording the program based on the recording reservation data input by the user is placed on the tray, A program is recorded based on the recording reservation data input by the user.
[0015]
Incidentally, if the user performs an operation of turning off the main power supply of the main body after placing the optical disk for recording the program based on the recording reservation data on the tray, it is possible to perform the operation without particularly performing the operation of closing the tray. The tray is moved to the closed state by the driving means, and the main power of the main body is turned off.
[0016]
When the tray is in a closed state a predetermined time before the recording start time included in the recording reservation data stored in the recording reservation data storage means and the main power is on, the recording reservation data is used. Do not perform recording. Therefore, when the user stops using a main unit for another purpose, such as stopping recording of a program for which recording has been reserved for some reason and viewing a program recorded on another optical disc, the user is not allowed to use the main unit. There is no hindrance.
[0017]
Thus, it is possible to prevent a situation in which the recording based on the recording reservation data is not executed when the user forgets to turn off the main power without hindering the use of the user.
[0018]
Whether the program based on the recording reservation data can be recorded on the optical disc mounted on the tray is determined by using a writable optical disc such as a DVD-R or a DVD-RW. If it is determined that recording is possible. In other words, if the optical disk is not writable, for example, a DVD-ROM, it is determined that recording is not possible.
[0019]
Further, it is determined whether or not the recording of the program based on the recording reservation data is possible, in addition to whether or not the size of the free space of the optical disk is large enough to record the program based on the recording reservation data. You may. In this way, it is possible to prevent a situation in which the recording of the program based on the recording reservation data ends prematurely due to the lack of the free space and the unnecessary recording is executed.
[0020]

[0022]
In FIG. 1, reference numeral 15 denotes a tray drive unit which moves between an open state in which a tray 17 on which a DVD 20 to be set in the main body is placed is protruded from the main body and a closed state stored in the main body, and 16 denotes a tray drive unit. The sensor is turned on (or off) when the tray 17 is in the open state, and is turned off (or on) when the tray 17 is in the closed state. The sensor 16 corresponds to a tray state detecting means according to the present invention. The sensor 16 is, for example, a photo sensor. When the tray 17 is closed, a part of the tray 17 is located between the light emitting element and the light receiving element. When the tray 17 is open, the tray 17 is closed. Is mounted at a location that is not located between the light emitting element and the light receiving element.

[0023]
Further, the sensor 16 may be a micro switch or the like that is turned on when the tray 17 is pressed and turned off when the tray 17 is not pressed. In this case, the sensor 16 may be mounted at a position where the sensor is not pressed by the tray 17 when the tray 17 is in the open state, and at a position where the sensor 16 is pressed by the tray 17 when the tray 17 is in the closed state.
[0024]
It should be noted that a configuration for holding and rotating the DVD 20 set in the main body and a configuration for moving the pickup head 10 in the radial direction of the DVD 20 are not illustrated.
[0025]
The control unit 2 is provided with a memory for storing the recording reservation data input to the main unit. FIG. 3 is a diagram showing a configuration of a recording reservation data storage area of the memory. The information constituting the recording reservation data includes a recording start time, a recording end time, a channel to be recorded, and the like. This memory is also used as a working area for temporarily storing data generated during operation. Further, the control unit 2 has a timer for measuring the current time.
[0026]
The receiving unit 3 is a known tuner that extracts a television broadcast signal of a selected channel from television broadcast signals received by the antenna 21. The AV data generation unit 4 generates AV data to be recorded on the DVD 20, for example, AV data compressed in the MPEG2 format, based on the television broadcast signal extracted by the reception unit 3. The recording unit 5 records the AV data generated by the AV data generation unit 4 on the DVD 20. Specifically, the AV data is recorded on the DVD 20 by controlling the power of the laser beam output from the pickup head 10 based on the AV data generated by the AV data generation unit 4.
[0027]
The reading unit 6 reads AV data recorded on the DVD 20 set in the main body, for example, AV data compressed in the MPEG2 format. Specifically, the pickup head 10 irradiates a laser beam to the DVD 20 set in the main body, and detects the reflected light. The reading unit 6 reads AV data recorded on the DVD 20 based on a change in the level of the reflected light detected by the pickup head 10. The AV data processing unit 7 processes the AV data read by the reading unit 6. For example, if the AV data read from the DVD 20 is MPEG2 format AV data, the AV data is expanded. The output unit 8 outputs an analog video signal and an audio signal. The input unit 9 has a plurality of input keys for performing an input operation on the main body, and a remote control receiving unit for receiving a control code transmitted from a remote control (not shown).
[0028]
Next, the operation of the optical disc device 1 according to the embodiment of the present invention will be described. The optical disk device 1 of this embodiment operates in two modes: a standby mode in which the main power is off, and an operation mode in which the main power is on.
[0029]
First, the operation in the standby mode will be described. FIG. 4 is a flowchart showing an operation in a standby mode of the optical disk device according to the embodiment of the present invention. The optical disk device 1 monitors whether there is an input to turn on the main power supply in the input unit 9 or that the current time reaches immediately before (several tens of seconds before) the recording start time of the recording reservation data stored in the main body. (S1, s2). When receiving an input to turn on the main power supply, the optical disk device 1 turns on the main power supply (s3) and shifts to an operation mode described later (s4).
[0030]
When the current time reaches just before the recording start time of the recording reservation data stored in the main body, the optical disc apparatus 1 prepares for recording start such as spinning up the DVD 20 set in the main body (s5). When the current time reaches the recording start time of the recording reservation data stored in the main unit (s6), recording of a program broadcast on a channel included in the reservation recording data is started (s7). Thereafter, when the current time reaches the recording end time, the optical disk device 1 ends the recording started in s7 (s8, s9), and returns to s1.
[0031]
The optical disk device 1 measures the current time with a timer provided in the control unit 2.
[0032]
As described above, the optical disc apparatus 1 of this embodiment performs recording based on the recording reservation data stored in the main body in the standby mode in which the main power is off.
[0033]
Next, the operation in the operation mode will be described. FIG. 5 is a flowchart showing the operation of the optical disk device in the operation mode. The optical disc apparatus 1 monitors whether there is any input in the input unit 9 (s11), or monitors whether the current time reaches a predetermined time (several minutes before) the recording start time of the recording reservation data stored in the main body. (S12). If there is any input in the input unit 9, the optical disk device 1 performs processing according to the input (s13), and returns to s11. The processing performed in s13 includes moving the tray 17 from the closed state to the open state (tray open), moving the tray 17 from the open state to the closed state (tray close), and playing back the DVD 20 set in the main body. The processing includes starting, stopping reproduction, and storing recording reservation data input to the main body in a memory.
[0034]
When the optical disc device 1 detects in s12 that the current time has reached a predetermined time (several minutes before) the recording start time of the recording reservation data stored in the main body, the tray 17 is open or closed. It is determined whether it is in the state (s14). The determination at s14 is made based on the on / off state of the sensor 16. If the optical disk device 14 determines that the tray 17 is in the closed state in s14, the process returns to s11.
[0035]
Note that the reason why the tray 17 is in the closed state in s14 is considered that the user has stopped recording the program reserved for recording for some reason and is using the main body for another purpose.
[0036]
When the optical disk device 1 determines that the tray 17 is in the open state in s14, the optical disc apparatus 1 moves the tray 17 from the open state to the closed state by the tray driving unit 15 (s15). Then, it is determined whether the DVD 20 is placed on the tray 17 (s16). When the DVD 20 is placed on the tray 17, the optical disk device 1 detects the type and free space of the DVD (s17). The DVD 20 is provided with an RMA (Recording Management Area) as an area for managing recorded information. By reading the information recorded in the RMA, the size of the free space of the DVD 20 can be calculated.
[0037]
The optical disk apparatus 1 is a writable DVD 20 (DVD-R, DVD-RW) placed on the tray 17 and its free space is larger than the size required for recording a program based on the recording reservation data. If it is larger (s18, s19), the main power is turned off (s20), and the mode shifts to the standby mode shown in FIG. 4 (s21).
[0038]
Therefore, when the DVD 20 for recording a program based on the recording reservation data input by the user is placed on the tray 17 and then the operation of turning off the main power of the main body and the operation of closing the tray 17 are forgotten, the optical disk device 1 moves the tray 17 from the open state to the closed state a predetermined time before the recording start time based on the reserved recording data, turns off the main power supply, and shifts to the standby mode. As described in the standby mode, when the recording start time comes, the recording based on the recording reservation data is executed. Therefore, after the DVD 20 for recording the program based on the recording reservation data input by the user is placed on the tray 17, the operation of turning off the main power of the main body and the operation of closing the tray 17 are forgotten. Also, a program is recorded based on the recording reservation data. In addition, by providing the process of s19, it is possible to prevent execution of useless recording in which recording of a program based on the recording reservation data is terminated halfway due to lack of free space on the DVD 20.
[0039]
If the optical disc apparatus 1 determines that the DVD 20 is not placed on the tray 17 in s17, is not a writable DVD (DVD-ROM) in s18, or has insufficient free space in s19, it performs recording. After waiting for the recording start time included in the reservation data (s22), the main power is turned off in s20, and the mode shifts to the standby mode in s21.
[0040]
As described above, if the recording based on the recording reservation data cannot be performed because the DVD 20 is not placed on the tray 17 or the like, the main power is turned off after the recording start time included in the recording reservation data. Since the mode is shifted to the standby mode, when the mode shifts to the standby mode, the recording start time included in the recording reservation data has passed. Therefore, the recording process based on the recording reservation data is not started in the standby mode. In addition, the state in which the main power is turned on is not kept forever, and power consumption of the main body can be suppressed.
[0041]
In addition, by providing the process of s14, if the user stops recording the program for which recording was reserved for some reason and it is considered that the main body is used for another purpose, the process from s15 is performed. There is no hindrance to user use.
[0042]
In the above-described embodiment, the present invention has been described with an apparatus in which the recording medium is the DVD 20. However, an optical disk other than the DVD 20, for example, a CD-R or a CD-RW used for recording a Video CD is used as the recording medium. The present invention can be applied to an apparatus.
[0043]
【The invention's effect】
As described above, according to the present invention, the operation of turning off the main power of the main body and the operation of closing the tray after placing the optical disk for recording the program based on the recording reservation data input by the user on the tray If the user forgets to record, the program is recorded based on the recording reservation data, so that it is possible to suppress a situation where the recording based on the recording reservation data is not executed without hindering the user's use.
