[1-1. Configuration of information processing system]
FIG. 1 is a diagram showing an overview of an information processing system according to the first embodiment of the present invention. With reference to FIG. 1, the outline of the information processing system according to the embodiment will be described.

  As illustrated in FIG. 1, an information processing system 10 according to the first embodiment of the present invention includes an information processing apparatus 100 as an example of a PC, and an optical drive 200 that performs processing according to a command from the information processing apparatus 100. It is what has. The optical drive 200 includes a tray 220, and the user opens the tray 220, places the optical disk on the tray 220, closes the tray 220, and causes the optical drive 200 to execute processing for handling data recorded on the optical disk. . In this embodiment, the information processing system 10 includes the optical drive 200 that handles an optical disc. However, the information processing system 10 takes in a recording medium by opening and closing the tray 220 instead of the optical drive 200. It is good also as having an apparatus which handles the data recorded on the recording medium.

  It is assumed that at least the information processing apparatus 100 is provided with an eject button E that the user presses to open and close the tray 220. In general, in addition to the eject button E provided in the information processing apparatus 100, the optical drive 200 is often provided with the eject button E. In the present embodiment, the optical drive 200 is particularly provided. The eject button E need not be provided.

  It is assumed that the information processing apparatus 100 is a notebook PC that can be carried by a user, but it is not always necessary to be able to carry it, and may be a stationary PC. The eject button E may be provided in any part of the information processing apparatus 100. For example, when the information processing apparatus 100 is a notebook PC, as shown in FIG. It may be provided on the side surface S of the processing apparatus 100. Further, the eject button E may be provided on the inner surface T of the information processing apparatus 100. The inner surface T is a portion that can be touched by the user when the lid 130 of the information processing apparatus 100 is opened, but cannot be touched by the user when the lid 130 of the information processing apparatus 100 is closed.

  In the present embodiment, the user opens the lid 130 of the information processing apparatus 100 when the information processing system 10 is used, and closes the lid 130 of the information processing apparatus 100 when the information processing system 10 is not used. Suppose. That is, the information processing apparatus 100 can determine that the user is using the information processing system 10 when the lid 130 is opened, and the user uses the information processing system 10 when the lid 130 is closed. It can be determined that they have not.

  In the present embodiment, when the information processing system 10 is used, the user displays the content displayed by an LCD (Liquid Crystal Display) 150 as an example of a display unit with the lid 130 opened. Assume browsing. For example, as shown in FIG. 1, the LCD 150 is provided on the inner surface T of the lid 130. That is, as described above, the information processing apparatus 100 can determine whether or not the user is using the information processing system 10 by opening and closing the lid 130, but can also determine by opening and closing the LCD 150. The information processing apparatus 100 includes the LCD 150 as an example of a display unit, but the display unit may be configured by another display device. Further, the display unit is not essential.

  For example, a case where the eject button E is provided at a place where the eject button E may be pressed regardless of the open / closed state of the lid 130 such as the side surface S is also assumed. For example, in such a case, it is beneficial to determine whether or not the user is using the information processing system 10 by opening and closing the lid 130. In other words, when the eject button E is pressed while the lid 130 is opened, the user may use the information processing system 10 to open and close the tray 220. Further, when the eject button E is pressed when the lid 130 is closed, it is assumed that the eject button E is pressed against the user's will even though the user is not using the information processing system 10. It can be determined not to open and close.

  In this embodiment, a method of opening and closing the tray 220 using a control device that is incorporated in the information processing apparatus 100 and can operate even when the information processing apparatus 100 is not powered on. Propose about. Accordingly, the tray 220 of the optical drive 200 can be opened and closed even when the information processing apparatus 100 is not powered on.

[1-2. Configuration of information processing system]
FIG. 2 is a diagram showing the configuration of the information processing system according to the first embodiment of the present invention. The configuration of the information processing system according to the embodiment will be described with reference to FIG.

  As shown in FIG. 2, the information processing system 10 according to the first embodiment of the present invention includes an information processing apparatus 100 and an optical drive 200. The information processing apparatus 100 includes an EC (Embedded Controller) 110, a CPU (Central Processing Unit) 140, an LCD 150, a North Bridge 160, a memory 170, a South Bridge 180, an HDD (Hard Disk Drive) 190, and the like as an example of a control apparatus. . The EC 110 and the optical drive 200 are connected by a predetermined communication path.

  The EC 110 is an LSI (Large Scale Integration) that is built in a notebook personal computer or the like as a standard, and is responsible for keyboard control, power management control of various power supply systems, and the like. In this embodiment, the EC 110 is used as an example of the control device, but a device other than the EC 110 may be used. In other words, the communication with the optical drive 200 via a predetermined communication path is enabled, and the optical drive 200 has a function of issuing a command, and can operate even when the information processing apparatus 100 is not turned on. If it is possible, other devices may be used.

  The CPU 140 has a function of controlling the operation of the information processing apparatus 100. The CPU 140 realizes the function by expanding the program stored in the HDD 190 in the memory 170 and executing the program expanded in the memory 170. There are various programs stored in the HDD 190, and an OS (Operating System) and the like are included therein. The HDD 190 has a function of storing data and programs used by the CPU 140. Since the HDD 190 is an example of a storage unit, another storage unit may be used instead of the HDD 190.

[1-3. Configuration of information processing system tray opening / closing section]
FIG. 3 is a diagram showing a configuration of a portion related to opening and closing of the tray of the information processing system according to the first embodiment of the present invention. With reference to FIG. 3, the structure of the part regarding tray opening / closing of the information processing system according to the embodiment will be described.

  As shown in FIG. 3, when the user presses the eject button E, the EC 110 detects the press of the eject button E. When the EC 110 detects pressing of the eject button E, the EC 110 outputs a power supply drive signal. The power supply drive signal is a signal for starting the supply of power to the optical drive 200, and can be output from the EC 110 by using a function already provided in the information processing system 10, for example. The flow of the power supply drive signal is controlled by an FET (Field Effect Transistor), and the voltage is limited by the regulator 240 included in the optical drive 200 to have power for starting the supply of power to the optical drive 200. A signal is supplied to the LSI 210. When the LSI 210 receives power supplied by the power supply drive signal, the LSI 210 performs processing to start supplying power to the optical drive 200 using the power. The LSI 210 functions as an example of a control unit.

  In addition, the EC 110 outputs an eject signal to the LSI 210 in a state where power supply to the power supply of the optical drive 200 is started. The timing at which the EC 110 outputs the eject signal is not particularly limited, but can be, for example, when a predetermined time t1 has elapsed since the power supply drive signal was output. The predetermined time t1 can be appropriately changed according to various parameters such as the time from when the EC 110 outputs the power supply drive signal to when the optical drive 200 is turned on. Further, the time t2 during which the ejection signal continues to be output (asserted time) t2 is not particularly limited, and can be appropriately changed according to the design of the LSI 210.

  As the eject signal, a signal for opening and closing the tray 220 already used by the optical drive 200 can be used. As a path used for transmitting the eject signal, a path already provided between the EC 110 and the optical drive 200 may be used, or a newly provided path may be used. When the LSI 210 receives an eject signal input from the EC 110, the LSI 210 performs a process of opening or closing the tray 220.

  Thus, the power supply drive signal and the eject signal are output from the EC 110 provided in the information processing apparatus 100. The EC 110 is operating even when power is not supplied to the information processing apparatus 100. That is, even when the information processing apparatus 100 is not turned on, the EC 110 can detect the pressing of the eject button E and output the power supply drive signal and the eject signal. When the optical drive 200 receives an input of a power supply drive signal, the optical drive 200 can turn on its power, and when it receives an eject signal, it can open or close the tray 220.

  If the EC 110 outputs an eject signal, the information processing apparatus 100 does not need to output the eject signal via the OS executed by the CPU 140 after detecting the pressing of the eject button E. Therefore, it is possible to quickly open and close the tray 220 by omitting the time required for the calculation for the ejection signal output by the OS.

[1-4. Functional configuration of control device]
FIG. 4 is a diagram illustrating a functional configuration of the control device according to the first embodiment of the present invention. With reference to FIG. 4, the functional configuration of the control device according to the embodiment will be described.

  As described above, the EC 110 functions as an example of a control device, is incorporated in the information processing apparatus 100, and can operate even when power is not supplied to the information processing apparatus 100. The EC 110 includes at least an ejection instruction detection unit 121, a power supply drive unit 122, and an ejection processing unit 123, and requires a state determination unit 124, an ejection execution notification unit 125, and a state acquisition unit 126. It is prepared accordingly.

  The eject instruction detecting unit 121 has a function of detecting a signal generated when the eject button E is pressed as an eject instruction. As described above, the eject button E may be provided on the side surface S of the information processing apparatus 100, may be provided on the inner surface T of the information processing apparatus 100, or may be provided on another side. It is good to be.

  The power supply drive unit 122 has a function of outputting a power supply drive signal for turning on the optical drive 200 when an ejection instruction is detected by the ejection instruction detection unit 121. The power supply drive signal output here is a signal for generating the power supplied to the optical drive 200 as described above. The optical drive 200 performs a process of turning on its own power using this power. As described above, for example, a function already provided in the EC 110 can be used as the function of the power supply drive unit 122 to output the power supply drive signal.

  The eject processing unit 123 has a function of outputting an eject signal for opening (or closing) the tray 220 provided in the optical drive 200. The timing at which the ejection processing unit 123 outputs the ejection signal is not particularly limited as described above. For example, after the power supply driving unit 122 outputs the power supply driving signal, only the predetermined time t1 is output. It can be when it has passed. In addition, the time t2 during which the ejection processing unit 123 continues to output the ejection signal is not particularly limited as described above, and can be appropriately changed according to the design of the LSI 210.

  The information processing apparatus 100 includes a state determination unit 124 and a state acquisition unit 126. The state determination unit 124 determines various states acquired by the state acquisition unit 126, and is output from the EC 110 according to the determination result. Various signals may be controlled.

  For example, the state acquisition unit 126 may acquire an open / close state that is information indicating whether or not the lid 130 of the information processing apparatus 100 is closed. In that case, the state determination unit 124 determines the open / closed state acquired by the state acquisition unit 126, and if it is determined that the lid 130 is closed, the power supply drive signal of the power supply drive unit 122 The output and the output of the eject signal by the eject processing unit 123 may be omitted. This is because, as described above, when the lid 130 is closed, there is a high possibility that the user is not using the information processing system 10, and the tray 220 needs to be opened and closed. This is because it is not expected.

  For example, the state acquisition unit 126 may acquire a startup state that is information indicating whether or not the OS being executed by the CPU 140 of the information processing apparatus 100 is started. In that case, the state determination unit 124 determines the activation state acquired by the state acquisition unit 126, and the ejection execution notification unit 125 determines that the OS is activated by the state determination unit 124. An eject notification, which is information indicating that the tray 220 has been opened, is notified to the OS. Thereby, the OS can detect the opening of the tray 220.

  The eject processing unit 123 may output a stop signal for turning off the power of the optical drive 200 when the state determination unit 124 determines that the OS is not activated. In that case, for example, when receiving an input of a stop signal, the optical drive 200 executes a process of turning off the power of the optical drive 200. As a case where the OS is not activated, a case where the information processing apparatus 100 is not turned on, a case where the OS is in a sleep state, a case where the OS is in a dormant state, or the like is assumed. In addition, as the case where the OS is activated, it is assumed that the OS is mainly activated. However, when the BIOS (Basic Input / Output System) is activated, the POST (Power On Self Test) is activated, etc. There may be.

  For example, the state acquisition unit 126 may acquire a power state that is information indicating whether or not the optical drive 200 is turned on. In that case, the state determination unit 124 determines the power supply state acquired by the state acquisition unit 126, and if it is determined that the optical drive 200 is turned on, the power supply drive unit 122 performs power supply drive. The output of the signal may be omitted.

[1-5. Tray opening process during power saving of information processing system]
In general, when the information processing apparatus 100 is not operated continuously for a predetermined time or more by the user while the OS installed in the information processing apparatus 100 is activated, the OS operates as the optical drive 200 as part of the power saving function. May be turned off. In such a case, there is a problem that the tray 220 cannot be opened and closed even when the eject button E provided in the optical drive 200 is pressed. Further, even if the eject button E provided in the information processing apparatus 100 is pressed, it is necessary to open and close the tray 220 through the OS. There is a problem that can not be done.

  Such a problem can be solved by applying the information processing apparatus 100 according to the present embodiment. Further, when both the information processing apparatus 100 and the optical drive 200 are provided with the eject button E, the user may not be able to easily determine which eject button E should be pressed. In the present embodiment, the eject button E may be provided in both the information processing apparatus 100 and the optical drive 200, but is provided in either the information processing apparatus 100 or the optical drive 200. Is more preferable.

  FIG. 5 is a diagram for explaining a tray opening process when the optical drive is not turned on during power saving of the information processing system according to the first embodiment of the present invention. With reference to FIG. 5, the tray opening process when the optical drive is not turned on at the time of power saving of the information processing system according to the embodiment will be described.

  As shown in FIG. 5, when the EC 110 detects that the eject button E has been pressed by an eject instruction (step S1), the EC 110 notifies the OS of ejection execution (step S2). The EC 110 outputs a power supply drive signal to turn on the optical drive 200 (step S3), and outputs an eject signal to the optical drive 200 (step S4). When the optical drive 200 receives the input of the eject signal, the optical drive 200 opens the tray 220 (step S5). The OS that has received the eject execution notification performs re-recognition of the optical drive 200 by the OS (step S6), and confirms that the tray 220 has been opened with the optical drive 200 (step S7).

  FIG. 6 is a diagram showing the flow of the tray opening process when the optical drive is not turned on when the information processing system according to the first embodiment of the present invention saves power. With reference to FIG. 6, the flow of the tray opening process when the optical drive is not turned on when the information processing system according to the embodiment saves power will be described.

  As shown in FIG. 6, when the user presses the eject button E when the optical drive 200 is not turned on in the power saving mode of the information processing apparatus 100, the EC 110 indicates that the eject button E has been pressed. Detect by. The EC 110 outputs a power supply drive signal to turn on the optical drive 200 and outputs an eject signal to the optical drive 200.

  When the optical drive 200 receives the input of the eject signal, the optical drive 200 opens the tray 220. Here, the LSI 210 of the optical drive 200 determines that it has received an eject signal when it receives a low level signal from the EC 110 for a predetermined time t2 or more, but it is understood that it has received an eject signal by another method. You may judge. The EC 110 issues an eject execution notification to the OS, and the OS that has received the eject execution notification recognizes the optical drive 200 in the OS and confirms that the tray 220 has been opened with the optical drive 200. For example, the OS may check the open / close state of the tray 220 to the optical drive 200 using an ATAPI (AT Attachment Packet Interface) command.

FIG. 7 is a diagram for explaining a tray opening process when the information processing apparatus according to the first embodiment of the present invention is not turned on. With reference to FIG. 7, the tray opening process when the information processing apparatus according to the embodiment is not turned on will be described.

  As shown in FIG. 7, when the EC 110 detects that the eject button E has been pressed by an eject instruction (step T1), it makes an open / close state acquisition request to the LCD open / close detection switch 230 (step T2), and the response LCD open / closed state notification is received (step T3). The LCD open / closed state corresponds to the open / closed state of the lid 130 in the above example. The open / closed state of the lid 130 is an example of a state acquired by the state acquisition unit 126.

  The EC 110 determines the LCD open / closed state, and if it is determined that the LCD 150 is open, the optical drive 200 is turned on by outputting a power supply drive signal (step T4), and the optical drive 200 is ejected. Is output (step T5). When the optical drive 200 receives the input of the eject signal, the optical drive 200 opens the tray 220 (step T6).

Transition to the state. The EC 110 outputs a power supply drive signal to turn on the optical drive 200 and outputs an eject signal to the optical drive 200.

  When the optical drive 200 receives the input of the eject signal, the optical drive 200 opens the tray 220. Here, the LSI 210 of the optical drive 200 determines that it has received an eject signal when it receives a low level signal from the EC 110 for a predetermined time t2 or more, but it is understood that it has received an eject signal by another method. You may judge. The EC 110 stops the power supply of the optical drive 200 by outputting a stop signal, and transitions to the sleep state.

If the eject instruction detection unit 121 determines that a change in the eject button E is not detected (“No” in step S101), the process ends. If it is determined that the change of the eject button E has been detected (“Yes” in step S101), the eject instruction detection unit 121 determines whether or not the eject button E has been pressed (step S102).

  If the eject instruction detection unit 121 determines that the eject button E has not been pressed (“No” in step S102), that is, if the pressed eject button E has been released, the process is terminated. If the eject instruction detection unit 121 determines that the eject button E has been pressed (“Yes” in step S102), the process proceeds to step S103.

  The state determination unit 124 of the information processing apparatus 100 determines whether the OS is running (step S103). If the state determination unit 124 determines that the OS is being started (“Yes” in step S103), the state determination unit 124 proceeds to step S104. If the state determination unit 124 determines that the OS is not being started (“No” in step S103). ”), The process proceeds to step S111. While the OS is starting up, as described above, various cases such as the BIOS starting up and the POST starting up may be included. In addition, when the OS is not running, as described above, there are various cases such as when the information processing apparatus 100 is not turned on, when the OS is in a sleep state, when the OS is in a dormant state, and so on. It may be included.

  The state determination unit 124 of the information processing apparatus 100 determines whether or not the OS is in a standby state (step S104). If the state determination unit 124 determines that the OS is in a standby state (“No” in step S104), the state determination unit 124 ends the process. If the state determination unit 124 determines that the OS is not in a standby state (“Yes” in step S104), the state determination unit 124 determines whether or not the optical drive 200 is turned on (step S105).

  If the state determination unit 124 of the information processing apparatus 100 determines that the optical drive 200 is turned on (“No” in step S105), the state determination unit 124 asserts an eject signal for a time t2 (step S110), and performs processing. Exit. As a case where the optical drive 200 is not turned on in this step, it is assumed that the OS has already been started. When the state determination unit 124 determines that the optical drive 200 is not turned on (“Yes” in step S105), the power supply drive unit 122 uses the power supply drive signal for turning on the optical drive 200. (Step S106), the ejection processing unit 123 waits for the time t1 (step S107), and then asserts the ejection signal for the time t2 (step S108). Next, the ejection execution notification unit 125 notifies the OS of ejection execution (step S109), and ends the process.

  The state determination unit 124 of the information processing apparatus 100 determines whether or not the LCD 150 is in a closed state (step S111). Here, step S111 is executed after step S103, but step S111 may be executed before step S103. If the state determination unit 124 determines that the LCD 150 is in a closed state (“Yes” in step S111), the state determination unit 124 ends the process. If the state determination unit 124 determines that the LCD 150 is in an open state (“No” in step S111), the state determination unit 124 determines whether or not the optical drive 200 is turned on (step S112).

  If the state determination unit 124 of the information processing apparatus 100 determines that the optical drive 200 is powered on (“No” in step S112), the process ends. If the state determination unit 124 determines that the optical drive 200 is not turned on (“Yes” in step S112), the power supply drive unit 122 uses the power supply drive signal for turning on the optical drive 200. (Step S113), the eject processing unit 123 waits for the time t1 (step S114), and then asserts the eject signal for the time t2 (step S115). Next, the ejection processing unit 123 outputs a stop signal to the optical drive 200 (step S116) and ends the process.

<2. Modification>
The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to such examples. It is obvious that a person having ordinary knowledge in the technical field to which the present invention pertains can come up with various changes or modifications within the scope of the technical idea described in the claims. Of course, it is understood that these also belong to the technical scope of the present invention.
