(Embodiment 1)
The embodiments of the invention according to claims 1 to 3, 9 to 11, 18 to 20, 26 to 28, 35 to 37, and 43 to 45 will be described with reference to FIGS. 1, 2, 3, 4, and 4. 5 will be described.

  FIG. 1 is a block diagram of a configuration when the information processing apparatus of the present invention is applied to a slot-in type CD-R / RW recording / reproducing apparatus. Reference numeral 1 denotes a removable medium, for example, a CD-ROM / R / RW, a DVD-ROM / R / RW, a DVD-RAM, a DVD-RAM with a cartridge, or a semiconductor memory medium. In the present embodiment, a case of a CD-R / RW disc will be described as an example. FIG. 2 is a perspective view showing an external appearance when a removable medium is inserted into a slot-in type CD-R / RW recording / reproducing apparatus. 3, 4, and 5 are flowcharts illustrating the flow of the medium LOAD / EJECT process of the information processing apparatus according to the present embodiment.

  In FIG. 1 and FIG. 2, reference numeral 2 denotes an information storage device, which loads the removable medium 1 to reproduce data in the removable medium 1 or record data on the removable medium 1. A host computer 3 is connected to the information storage device 2 by the interface device 4, and sends various operation commands to the information storage device 2 through the interface device 4 or data reproduced by the information storage device 2. Or take action. The interface device 4 generally uses, for example, an interface standardized for communication between a computer and an information storage device, such as ATAPI, SCSI, USB, and IEEE1394. Of course, even if an interface device 4 other than these standards is used, it can be similarly implemented if data and commands can be exchanged between the host computer 3 and the information storage device 2.

  A power supply device 5 is a power supply device 7 that is turned ON / OFF by a power switch 6 and a constant power supply device 8 that always supplies power as long as power is supplied to the power supply device 5 even if the power switch 6 is operated. It consists of. The power supply device 7 supplies power to the host computer 3 and the main power supply operating unit 9 in the information storage device 2. The main power supply operating unit 9 in the information storage device 2 is for operating the main functions of the information storage device 2, and includes a load / eject control unit 10, a CPU 11, a medium transport device 12, a removable medium playback device (not shown), and the like. Is included. The constant power supply device 8 supplies power to the power control device 13 in the information storage device 2. The power supply control device 13 controls the supply and stop of the power supply by the power supply device 7. The power supply control device 13 is always operated from the power supply device 8 while the power supply of the host computer 3 and the main power supply operating unit 9 is shut off. The minimum necessary power is supplied and operating.

  Reference numeral 17 is a medium discharge switch, and 18 is a medium insertion detection switch. The medium discharge switch 17 is provided outside the information storage device 2 and performs a medium discharge operation when pressed by the user. The medium insertion detection switch 18 is provided inside the device 2 and detects that the removable medium 1 has been inserted into the information storage device 2. When power is supplied from the power supply device 7 based on the detected switch state or change in the switch state, the CPU 11 connected to the switch 18 determines necessary processing and performs load / eject control. The unit 10 is operated, and the medium transport device 12 is driven to perform the LOAD / EJECT operation. For example, in the slot loading type information storage device, the medium transport device 12 is configured by a combination of a roller for transporting the medium 1 and a spring or gear for transporting the medium 1. In the slot loading type information storage device 2 of the present embodiment, as shown in FIG. 2, the removable medium 1 is automatically inserted into the inside of the device by directly inserting the removable medium 1 into the medium insertion slot 21 of the information storage device 2. In the same manner, the removable medium 1 is directly discharged from the medium insertion opening 21 when discharged.

Next, details of an actual operation for performing LOAD / EJECT will be described.
First, the operation when power is supplied from the power supply device 7 to the host computer 3 and the main power supply operating unit 9 will be described. When power is supplied to the main power supply operating unit 9, the CPU 11 controls the power supply control device 13 so that the power supply control operation of the power supply device 7 by the power supply control device 13 is not performed. For example, when the power supply of the main power supply operating unit 9 of the information storage device 2 is started, or when the CPU 11 is reset by hardware, the medium control switch 13 is pressed down as a power supply start factor. Alternatively, if it is not set that the state of the medium insertion detection switch 18 has changed, an output port from the CPU 11 to the power supply control device 13 is prepared. If the output state from the CPU 11 is H, the power supply control is performed. The device 13 may be stopped.

  When the medium discharge switch 17 is pressed in this state, the process A in FIG. 3A is executed. When it is determined in S301 that the removable medium 1 is loaded in the information storage device 2, if the CPU 11 detects that the medium discharge switch 17 is pressed, the load / eject control unit 10 is operated in S302 to The transport device 12 is driven to eject the removable medium 1 to the outside of the information storage device 2. Of course, if the removable medium 1 is rotating as a disk-shaped storage medium at this time, the disk is ejected after stopping the rotation, and if it is a non-disk medium such as a semiconductor memory, it is necessary to stop access. Naturally, the discharge is performed after the processing is performed.

When the removable medium 1 is not loaded in the information storage device 2, the slot loading type information storage device of the present embodiment performs no operation.
After the above processing is completed, the information storage device 2 is set in a standby state in S303. The standby state is a state in which power is supplied to the main power supply operating unit 9 of the information storage device 2, and the operation of unnecessary circuit blocks in the information storage device 2 is stopped to obtain the minimum necessary power consumption. That means. At this time, since the power supply control device 13 is in a non-operating state, the power supply from the power supply device 7 is continued in S304.

  Next, an operation when the logic of the medium insertion detection switch 18 is changed will be described. In the slot loading type information storage device 2 according to the present embodiment, when the removable medium 1 is inserted directly from the medium insertion port 21 to a certain position, the medium insertion detection switch 18 detects the insertion of the removable medium 1. At this time, the change in the logic of the medium insertion detection switch 18 varies depending on the structure of the mechanism. For example, the logic is turned ON (or OFF) when the removable medium 1 is inserted to a certain position, and further turned OFF (or ON) when the medium transport device 12 is operated and pulled into the information storage device 2. Cases that change or turn ON (or OFF) when the removable medium 1 is inserted to a certain position, and keep the ON (or OFF) state while the removable medium 1 is in the information storage device 2 thereafter. There are various cases.

  When the CPU 11 detects a change in the logical state of the medium insertion detection switch 18, the process B in FIG. 3B is executed. In S305, the load / eject control unit 10 is operated in accordance with the switch logic change of the medium loading sequence based on the structure of the information storage device 2 to drive the medium transport device 12, and the removable medium 1 is placed in the information storage device 2. At step S306, the recording / reproduction is enabled. For example, in the CD-R / RW recording / reproducing apparatus, the type of the medium 1 is discriminated, adjustments necessary for the recording / reproducing operation corresponding thereto, and acquisition of the disc information are performed, and the recording / reproducing state is enabled. After that, in step S307, the removable medium 1 is recorded / reproduced according to a command from the host computer 3. Even after these processes are completed, since the power supply control device 13 is in a non-operating state, the power supply by the power supply device 7 is continued in S308.

  Next, the operation in the case where power is not supplied from the power supply device 7 to the host computer 3 and the main power supply operating unit 9 and power is supplied only to the power supply device 13 by the constant power supply device 8 will be described. To do. When no power is supplied to the main power supply operating unit 9, the power supply control device 13 is in a state in which the power supply device 7 can supply power and control operations for stopping the power supply.

  In this state, when the medium ejection switch 17 is pressed (execution of process C in FIG. 4A) or the logical state of the medium insertion detection switch 18 changes (execution of process D in FIG. 4B) First, the power supply control device 13 detects that the medium discharge switch 17 or the medium insertion detection switch 18 has been pressed, and controls the power supply device 7 in S401 to control the main power supply operating unit 9 and the host computer 3. Start supplying power to the. At this time, the power supply control device 13 notifies the CPU 11 that the logic of the medium ejection switch 17 or the medium insertion detection switch 18 has changed while the power supply device 7 is stopped (S402). Specifically, for example, the CPU 11 includes a device that accesses a register on the power supply control device 13, and information on the switch whose state has changed is stored in the register after the main power supply operating unit 9 is turned on or reset. Depending on the logic state, the reason why the power is turned on is that the medium ejection switch 17 is pressed, the logic state of the medium insertion detection switch 18 is changed, or the power switch regardless of the change in the state of either switch. 6 determines whether the power is turned on.

  The CPU 11 determines whether or not the removable medium 1 exists in the information storage device 2 when the medium discharge switch 17 in FIG. 4A is pressed and the power supply is started due to the detected power-on factor. (S403). If a medium is present, a medium ejection operation (S404) is performed, and the information storage device 2 is set to a standby state in S412. If there is no medium, no operation is performed (S405), and the information storage device 2 is set in a standby state in S412.

  If the logical state of the medium insertion detection switch 18 changes in FIG. 4B, the load / eject control unit 10 is operated in S407 according to the switch logical change of the medium loading sequence on the structure of the information storage device 2. Then, the medium transporting device 12 is driven, and the removable medium 1 is drawn into the information storage device 2 so that it can be recorded and reproduced in S408. For example, in a CD-R / RW recording / reproducing apparatus, the type of medium is determined, adjustments necessary for the recording / reproducing operation corresponding thereto, and acquisition of disc information are performed, and recording / reproducing becomes possible. After that, in S409, the data in the removable medium 1 can be reproduced or recorded on the host computer 3.

  As in process E of FIG. 5A, when there is no change in the state of any of the switches and the power switch 6 is pressed and power supply is started, first, in S501, the power supply device 7 and the constant power supply device 8 Both start supplying power from the state where they are shut off. As a result, when the information storage device 2 is reset by hardware, a normal initial operation at power-on is performed. In this initial operation, after the power supply is started by the power supply device 7, the power supply control device 13 is disabled as described above (S502). For example, whether or not the removable medium 1 is loaded in the device is checked. If it is loaded, an operation for enabling recording / reproduction is performed (S504), and a reproduction or recording operation for data in the medium 1 is performed according to a command from the host computer 3 as necessary (S505). ). If not loaded, the information storage device 2 is set in a standby state in S506.

  Further, it is possible to further control the power supply of the main power supply operating unit 9 and the host computer 3 according to the factor that the power supply is started. For example, after the medium discharge switch 17 is pressed and the power supply is started and the medium discharge operation is performed, the information storage device 2 is set in a standby state in S412 of FIG. 13, the power supply start factor is reset and the power supply to the main power supply operating unit 9 and the host computer 3 by the power supply device 7 is stopped in S406. Thereby, when the medium discharge switch 17 is pressed in the power supply cut-off state, the power of the main power supply operating unit 9 and the host computer 3 can be cut off after performing the medium discharge operation.

  Further, when the logical state of the medium insertion detection switch 18 is changed and power supply is started and the removable medium 1 is loaded into the information storage device and is ready for recording and reproduction, S410 in FIG. In step S411, the power control device 13 becomes inoperable by resetting and canceling the factor information that the power supply is started by controlling the power control device 13, and in the next S411, the main power supply operating unit 9, the host The power supply of the computer 3 is continued as it is. If the logical state of the medium insertion detection switch 18 changes and power supply is started, but the removable medium 1 cannot be loaded into the information storage device 2 or the removable medium 1 does not exist, the CPU 11 Then, the power supply control device 13 is controlled, and the power supply device 7 can stop the power supply of the main power supply operating unit 9 and the host computer 3.

  When the power switch 6 is pressed and the power supply device 7 starts to supply power to the main power supply operating unit 9 and the host computer 3, both from the state where both the power supply device 7 and the constant power supply device 8 are shut off. When the power supply devices 7 and 8 start supplying power, the power supply control device 13 is in an inoperable state regardless of the presence or absence of the removable medium 1, so that the power supply of the power supply device 7 is continued. (S507).

  As for the operation when the power is shut off, as in the process F of FIG. 5B, either when the power supply of the power supply device 7 is cut off by the control of the power control device 13 or by the operation of the power switch 6. In S509, the inoperable command state of the power supply device 13 from the CPU 11 is released, and in S510, the power supply control device 13 is in an operable state.

  In the first embodiment, the case where the operation or inoperability of the power supply control device 13 is performed by the control from the port from the CPU 11 has been described as an example, but the power supply state of the power supply device 7 is monitored by the power supply control device 13. It can be similarly implemented by various methods such as a method.

  In the first embodiment, no operation is performed when the removable medium 1 is not present in the information storage device 2 while the main power supply operating unit 9 of the information storage device 2 is being supplied with power. The case where the information storage device 2 is set to the standby state has been described as an example, but in order to prevent a failure that cannot normally detect the presence of the removable medium 1 in the information storage device 2 from occurring and the medium cannot be ejected. Similarly, the load / eject control unit 10 is operated to drive the medium conveying device 12 to perform the medium discharging operation.

  In the first embodiment, when the main power supply operating unit 9 of the information storage device 2 is being supplied with power and the removable medium 1 does not exist in the information storage device 2, the information storage device 2 is put on standby. Although the case of setting the state has been described as an example, setting the standby state is a general operation of the information storage device, and can be similarly performed even when the standby state is not set.

  In the first embodiment, the case where the ejection operation of the removable medium 1 is performed by starting the power supply of the information storage device 2 by the operation of the medium ejection switch 17 has been described as an example. The medium discharging operation can be performed without power supply and the medium loading operation can be similarly performed even when the method described in this embodiment is used.

  In the first embodiment, the method in which the CPU 11 detects the factor that the power supply is started based on the register information of the power control device 13 has been described as an example. However, after the power control device 13 detects the operation of the medium discharge switch 17, Alternatively, after detecting the logic change of the medium insertion detection switch 18, the terminal connected to each switch is switched to the output terminal so as to maintain the logic state, and the changed logic state is maintained and input to the CPU 11. Further, after using one terminal connected to the CPU 11 to set a logic state (for example, normally when L is switched on and power is turned on due to a switch factor) to notify that the power is turned on due to a switch state change, In addition, power supply is started, such as a method of controlling the power supply device 7 to start power supply to the main power supply operating unit 9 and the host computer 3. It is equally capable of in any way as long as possible to notify factors to CPU 11.

  As described above, although the power supply control device 13 cannot stop the power supply, it can be realized with a very simple small-scale logic circuit, as in a normal information storage device standby or sleep state. In addition, it is possible to achieve much lower power consumption than the case where the power supply for each block is cut off inside the IC and only the necessary blocks are supplied with power.

  Therefore, according to the present embodiment, particularly in the slot loading type information storage device, power is supplied only to the power supply control device 13 while the power supply to the host computer 3 and the main power supply operating unit 9 is stopped. Therefore, the power consumption when the power supply of the entire apparatus is stopped can be minimized, and a change in the pressed state of the plurality of switches 6, 17, 18 included in the information storage device 2 can be detected and the power can be supplied as necessary. The supply can be started and the load / eject operation can be appropriately performed according to the logical states of the plurality of switches 6, 17, and 18, and the power supply device 7 is controlled according to the performed load / eject operation to Since power supply to the power supply operating unit 9 and the host computer 3 is stopped or continued, the information processing apparatus 2 is loaded after loading by inserting the medium 1. It is possible to provide a power supply control method for an information processing apparatus and an information processing apparatus capable of performing processing according to the contents of the medium 1 automatically.

(Embodiment 2)
Embodiments according to claims 12 to 14, claims 29 to 31, and claims 46 to 48 will be described below with reference to FIGS. 6, 7, 8, 9, and 10. FIG.

  FIG. 6 is a block diagram of a configuration when the information processing apparatus of the present invention is applied to a tray type CD-R / RW recording / reproducing apparatus. Reference numeral 1 denotes a removable medium, for example, a CD-ROM / R / RW, a DVD-ROM / R / RW, a DVD-RAM, a DVD-RAM with a cartridge, or a semiconductor memory medium. In the present embodiment, a case of a CD-R / RW disc will be described as an example. FIG. 7 is a perspective view showing an external appearance when a removable medium is inserted into a tray type CD-R / RW recording / reproducing apparatus. 8, 9, and 10 are flowcharts showing the flow of the medium LOAD / EJECT process of the information storage device according to the second embodiment.

  In FIG. 6 and FIG. 7, reference numeral 2 denotes an information storage device, which loads the removable medium 1 and reproduces data in the removable medium 1 or records data on the removable medium 1. Reference numeral 3 denotes a host computer, which is connected to the information storage device 2 and the interface device 4, and sends various operation commands to the information storage device 2 through the interface device 4, and data reproduced by the information storage device 2. Or take action. The interface device 4 generally uses, for example, an interface standardized for communication between a computer and an information storage device, such as ATAPI, SCSI, USB, and IEEE1394. Of course, even if an interface device 4 other than these standards is used, it can be similarly implemented if data and commands can be exchanged between the host computer 3 and the information storage device 2.

  A power supply device 5 is a power supply device 7 that is turned ON / OFF by a power switch 6 and a constant power supply device that always supplies power as long as power is supplied to the power supply device 5 even if the power switch 6 is turned OFF. 8. The power supply device 7 supplies power to the host computer 3 and the main power supply operating unit 9 in the information storage device 2. The main power supply operating unit 9 in the information storage device 2 is for operating the main functions of the information storage device 2, and includes a load / eject control unit 10, a CPU 11, a removable medium playback device (not shown), and the like. The constant power supply device 8 supplies power to the power control device 13 in the information storage device 2. The power supply control device 13 is operated with the minimum power necessary for operation while the power supply of the host computer 3 and the main power supply operating unit 9 is cut off.

  32 is a tray discharge detection switch, and 34 is a tray operation switch. The tray operation switch 34 is provided outside the information storage device 2 and performs the LOAD / EJECT operation of the medium transport tray 31 when pressed by the user. The tray discharge detection switch 32 is a switch provided inside the apparatus 2 and detects that the medium transport tray 31 is completely discharged.

  When power is supplied from the power supply device 7 based on the detected switch state or change in the switch state, the CPU 11 determines the necessary processing and operates the load / eject control unit 10 to operate the tray. The drive device 33 is driven to perform a LOAD / EJECT operation. For example, in the tray loading type information storage device, the tray driving device 33 is generally known to drive the medium carrying tray 31 by combining a loading motor, a gear, and a gear provided on the medium carrying tray 31. Yes. In the tray loading type information storage device 2 according to the second embodiment, the user presses the tray operation switch 34 after the removable medium 1 is directly placed on the medium transport tray 31 as shown in FIG. Alternatively, the removable medium 1 is automatically conveyed into the apparatus 2 for recording by pushing the medium conveyance tray 31 directly into the information storage apparatus 2 to change the logical state of the tray discharge detection switch 32. Reproducible state. Similarly, when the user depresses the tray operation switch 34, the removable medium 1 is ejected to the outside of the apparatus 2 together with the medium transport tray 31. When the medium transport tray 31 is completely discharged to the outside of the apparatus 2 and the logical state of the tray discharge detection switch 32 changes, the discharge operation is stopped.

Next, details of an actual operation for performing LOAD / EJECT will be described.
First, the operation when power is supplied from the power supply device 7 to the host computer 3 and the main power supply operating unit 9 will be described. When power is supplied to the main power supply operating unit 9, the CPU 11 controls the power supply control device 13 so that the power supply operation of the power supply device 7 is not performed. For example, an output port from the CPU 11 to the power supply control device 13 is prepared, and if the output state from the CPU 11 is H, the power supply control device 13 may be in a stopped state, that is, a non-operating state.

  In this state, when the tray operation switch 34 is pressed and the logic of the tray discharge detection switch 32 is not in the tray discharge state, the process G in FIG. 8A is executed. That is, regardless of whether or not the removable medium 1 is loaded in the information storage device 2, when the CPU 11 detects pressing of the tray operation switch 34, the load / eject control unit 10 is operated in S 801, and the tray drive device 33. To discharge the medium transport tray 31 to the outside of the information storage device 2. When the medium transport tray 31 is completely ejected to the outside of the information storage device 2, as described above, the logical state of the tray eject detection switch 32 changes, and this is detected by the CPU 11 and the eject operation of the medium transport tray 31 is performed. finish. Of course, if the removable medium 1 is present in the information storage device 2 and the removable medium 1 is a disk-shaped storage medium and is rotating at this time, the rotation is stopped and the discharge is performed. In the case of a non-disk medium such as a memory, it is natural that necessary processing such as access stop is performed. After that, in S802, the information storage device 2 is set in a standby state. After these processes are completed, the power supply control device 13 is in a non-operating state, and thus the power supply of the power supply device 7 is continued in S803.

  When the tray operation switch 34 is pressed and the tray discharge detection switch 32 is in the tray discharge state, or when the tray discharge detection switch 32 is changed from the tray discharge state, the process H in FIG. 8B is executed. The Here, when the CPU 11 detects the depression of the tray operation switch 34 or the state change of the tray discharge detection switch 32, the load / eject control unit 10 is operated in S804, and the tray driving device 33 is driven to move the medium transport tray 31. It is pulled into the information storage device 2. In step S805, the presence / absence of the removable medium 1 is detected. If the removable medium 1 is not placed on the medium transport tray 31, the information storage device 2 is set in a standby state in step S809. If the removable medium 1 is placed on the medium transport tray 31, the medium 1 is set in a recordable / reproducible state in S806. For example, in a CD-R / RW recording / reproducing apparatus, the type of medium is determined, adjustments necessary for the recording / reproducing operation corresponding thereto, and acquisition of disc information are performed, and recording / reproducing becomes possible. After that, in step S807, the removable medium 1 is recorded / reproduced according to a command from the host computer 3.

Even after these processes are completed, since the power supply control device 13 is in a non-operating state, the power supply of the power supply device 7 is continued in S808.
Next, the operation when power is not supplied from the power supply device 7 to the host computer 3 and the main power supply operating unit 9 and power is supplied only from the power supply device 8 to the power control device 13 will be described. . When the main power supply operating unit 9 is not supplied with power, the power supply control device 13 is in an operable state.

  When the tray operation switch 34 is pressed in this state, when the power supply control device 13 detects the pressing of the tray operation switch 34, the process I of FIG. 9A is executed. First, in step S <b> 901, the power supply device 7 is controlled to start power supply to the main power supply operating unit 9 and the host computer 3. At this time, in step S <b> 902, the power supply control device 13 notifies the CPU 11 that the tray operation switch 34 has been pressed while the power supply device 7 is stopped. Specifically, for example, the CPU 11 includes a device that accesses a register on the power supply control device 13, and the switch whose state has changed in the register after the main power supply operating unit 9 is turned on or when the information storage device 2 is reset. Information is stored, and depending on the logical state, the power is turned on regardless of whether the tray operation switch 34 is pressed, the logical state of the tray discharge detection switch 32 is changed, or neither switch is changed. The power switch 6 determines whether the power is turned on. The CPU 11 performs a loading or ejecting operation according to the detected power-on factor and the state of the medium transport tray 31 (S903). If the tray discharge detection switch 32 is in the tray discharge state, in S904, the load / eject control unit 10 is operated to drive the tray drive device 33 so that the medium transport tray 31 is placed inside the information storage device 2. In step S905, the presence / absence of the removable medium 1 is detected. At this time, if the removable medium 1 is not placed on the medium transport tray 31, the information storage device 2 is set in a standby state in S906. If the removable medium 1 is placed on the medium transport tray 31, the recording / reproducing state is set in S907. For example, in the CD-R / RW recording / reproducing apparatus, the type of the medium 1 is discriminated, and the recording / reproducing operation necessary for the recording / reproducing operation corresponding to the medium 1 is performed, and the recording / reproducing state is enabled.

  When the tray operation switch 34 is pressed, the power supply is started. If the tray discharge detection switch 32 is not in the tray discharge state in S903, the CPU 11 operates the load / eject control unit 10 in S910 to operate the tray. The drive device 33 is driven to discharge the medium transport tray 31 to the outside of the information storage device 2. When the medium transport tray 31 is completely ejected to the outside of the information storage device 2, as described above, the logical state of the tray eject detection switch 32 changes, and this is detected by the CPU 11 and the eject operation of the medium transport tray 31 is performed. finish. After that, in S906, the information storage device 2 is set in a standby state.

  If the logical state of the tray discharge detection switch 32 changes from the discharge state while the power supply control device 13 is in an operable state, the process J of FIG. 9B is executed. That is, first, in S911, the power supply device 7 is controlled to start power supply to the main power supply operating unit 9 and the host computer 3. At this time, in S912, the power supply control device 13 notifies the CPU 11 that the logical state of the tray discharge detection switch 32 has changed while the power supply device 7 is stopped. Thereafter, when the depression of the tray operation switch 34 is detected, the load / eject control unit 10 is operated in S904 to activate the tray drive device 33 in the same manner as when the tray discharge detection switch 32 is in the tray discharge state. Driven to pull the medium transport tray 31 into the information storage device 2. Next, the presence or absence of the removable medium 1 is detected in S905, and when the removable medium 1 is not placed on the medium transport tray 31, the information storage device 2 is set in a standby state in S906. If the removable medium 1 is placed on the medium transport tray 31 in S905, the recording / reproducing state is set in S907. For example, in the CD-R / RW recording / reproducing apparatus, the type of the medium 1 is discriminated, and the recording / reproducing operation necessary for the recording / reproducing operation corresponding to the medium 1 is performed, and the recording / reproducing state is enabled. After that, in S908, the power supply control device 13 becomes inoperable by resetting the power supply start factor. After that, in S909, the data in the removable medium 1 can be reproduced or recorded on the host computer 3.

  When the power switch 6 is pressed and the power supply is started without any change in the state of any of the switches 32 and 34 as in the process K of FIG. 10, both the power supply device 7 and the constant power supply device 8 are shut off. The power supply is started from the state that has been performed (S1001). As a result, the information storage device 2 is reset by hardware, and a normal initial operation is performed when the power is turned on. In this initial operation, for example, when the CPU 11 is initialized as described above, the power supply start factor of the power supply control device 13 is checked, and the power supply control device 13 is operated when the power supply start factor is not set. In step S1002, the tray discharge detection switch 32 is checked to determine whether or not the medium transport tray 31 is in a discharge state. If the medium transport tray 31 is in the ejected state, a tray loading process is performed in S1004. If it is not in the ejected state and after performing the tray loading process, it is determined whether the removable medium 1 is loaded in the apparatus, for example (S1005). If it is loaded, an operation for enabling recording / reproduction is performed (S1006), and data in the medium is reproduced or recorded as required by a command from the host computer 3 (S1007). If it is not loaded, the information storage device 2 is set in a standby state in S1008.

Further, it is possible to further control the power supply of the main power supply operating unit 9 and the host computer 3 according to the factor that the power supply is started.
For example, when the tray operation switch 34 in FIG. 9A is pressed to start the power supply and the tray ejection operation is performed, or the tray operation switch 34 is pressed to start the power supply, and the medium is transferred into the information storage device 2. When the tray 31 is loaded and the removable medium 1 does not exist in the medium transport tray 31, or when the tray discharge detection switch 32 in FIG. When the medium transport tray 31 is loaded and the removable medium 1 does not exist in the medium transport tray 31, the power supply start factor is reset in S908, and then the power control device 13 is connected from the CPU 11 to the CPU 11 in S913. The power of the main power supply operating unit 9 and the host computer 3 by the power supply device 7 is controlled. By stopping the supply can be cut off the main power operating section 9, the power of the host computer 3.

  Further, when the tray operation switch 34 in FIG. 9A is pressed, power supply is started, and the removable medium 1 is loaded into the information storage device 2 to enable recording and reproduction, or in FIG. 9B. When power supply is started by changing the state of the tray discharge detection switch 32 and the removable medium 1 is loaded into the information storage device 2 to enable recording and reproduction, the power supply start factor is reset in S908. As a result, the power supply control device 13 becomes inoperable. After that, in S909, the data in the removable medium 1 can be reproduced or the recording process can be performed on the host computer 3, and the power supply from the power supply device 7 is continued (S914).

  In FIG. 10, when the power switch 6 is pressed and the power supply device 7 starts to supply power to the main power supply operating unit 9 and the host computer 3, both the power supply device 7 and the constant power supply device 8 are shut off. When both 7 and 8 start supplying power from the state, the power supply control device 13 is in an inoperable state regardless of the presence or absence of the removable medium 1, so that the power supply of the power supply device 7 is continued. (S1009).

  The operation when the power is shut off is the same as that in the first embodiment, and the power supply of the power supply device 7 is controlled by the power control device 13 or by the operation of the power switch 6 as in the process F of FIG. In any case where the supply is interrupted, in S509, the inoperable command state of the power supply device 13 from the CPU 11 is canceled, and in S510, the power control device 13 becomes operable.

  In the second embodiment, the case where the operation or inoperability of the power supply control device 13 is performed by the control from the port from the CPU 11 has been described as an example. However, the power supply control device 13 monitors the power supply state of the power supply device 7. It can be similarly implemented by various methods.

  In the second embodiment, the case where the discharge operation of the medium transport tray 31 is performed by starting the power supply of the main power supply operating unit 9 by the operation of the tray operation switch 34 has been described as an example. Even when the tray discharge operation is performed without power supply using the discharge mechanism, and only the tray loading operation is performed by the method described in the second embodiment, the same operation can be performed.

  In the second embodiment, when the main power supply operating unit 9 of the information storage device 2 is being supplied with power, the removable medium 1 is not present in the information storage device 2, or the medium transport tray 31 is used. The case where the information storage device 2 is set in the standby state when the state is discharged is described as an example. However, setting the standby state is a general operation of the information storage device 2 and can be similarly performed even when the standby state is not set.

  In the second embodiment, the example in which the CPU 11 detects the factor of the start of power supply based on the register information of the power control device 13 has been described as an example. However, the power control device 13 detects the tray operation switch 34 or the tray discharge detection. After detecting the logical change of the switch 32, the terminals connected to the respective switches 32 and 34 are switched to output terminals so as to maintain the logical state, and the changed logical state is maintained and input to the CPU 11, and further After setting a logic state (for example, normally L, or H when power is turned on due to a switch factor) using one terminal connected to the CPU 11 to notify that the power has been turned on due to a switch state change The power supply is started, such as the one that controls the power supply device 7 to start the power supply of the main power supply operating unit 9 and the host computer 3. If it is possible to notify the factor CPU 11, it can be implemented similarly not limited.

  As described above, although the power supply control device 13 cannot stop the power supply, it can be realized with a very simple small-scale logic circuit, like a standby or sleep state of a normal information storage device. In comparison with the case where the power supply for each block is cut off inside the IC and only the necessary blocks are supplied with power, the power consumption can be made much smaller.

  Therefore, according to the second embodiment, especially in the tray loading type information storage device, power is supplied only to the power supply control device 13 while the power supply to the host computer 3 and the main power supply operating unit 9 is stopped. Therefore, power consumption when the power supply of the entire apparatus is stopped can be minimized, and a change in the pressed state of a plurality of switches provided in the information storage device 2 is detected and power supply is started as necessary. The load / eject operation can be appropriately performed according to the logic states of the plurality of switches, and the power supply device 7 is controlled according to the performed load / eject operation to control the main power supply operating unit 9 and the host computer 3. Since the power supply is stopped or continued, processing according to the contents of the medium 1 can be automatically performed after loading by inserting the medium. Power supply control method of the kill information processing apparatus and an information processing apparatus can be provided.

(Embodiment 3)
Embodiments according to claims 15 to 17, claims 32 to 34, and claims 49 to 51 will be described below with reference to FIGS. 11, 12, 13, 14, and 15. FIG.

  FIG. 11 is a block diagram of a configuration when the present invention is applied to a slim tray type CD-R / RW recording / reproducing apparatus. Reference numeral 1 denotes a removable medium, for example, a CD-ROM / R / RW, a DVD-ROM / R / RW, a DVD-RAM, a DVD-RAM with a cartridge, or a semiconductor memory medium. In the present embodiment, a case of a CD-R / RW disc will be described as an example. FIG. 12 is a perspective view showing an external appearance when a removable medium is loaded in a slim tray type CD-R / RW recording / reproducing apparatus.

  In FIG. 11 and FIG. 12, reference numeral 2 denotes an information storage device, which loads the removable medium 1 to reproduce data in the removable medium 1 or record data on the removable medium 1. A host computer 3 is connected to the information storage device 2 and the interface device 4, and sends various operation commands to the information storage device 2 through the interface device 4, and stores data reproduced by the information storage device 2. An operation such as receiving processing is performed. The interface device 4 generally uses, for example, a standardized interface for communication between a computer and an information storage device, such as ATAPI, SCSI, USB, and IEEE1394. Of course, even if an interface device other than these standards is used, it can be similarly implemented if data and commands can be exchanged between the host computer 3 and the information storage device 2.

  A power supply device 5 is a power supply device 7 that is turned ON / OFF by a power switch 6 and a constant power supply device 8 that always supplies power as long as power is supplied to the power supply device 5 even if the power switch 6 is operated. It consists of. The power supply device 7 supplies power to the host computer 3 and the main power supply operating unit 9 in the information storage device 2. The main power supply operating unit 9 in the information storage device 2 is a block for operating the main function of the information storage device 2, and includes an eject control unit 55, a CPU 11, and the like. A medium loading tray 52 includes a tray lock releasing device 51, a removable medium reproducing device (not shown), and the like, and similarly operates by power supply from the power supply device 7. The constant power supply device 8 supplies power to the power control device 13 in the information storage device 2. The power supply control device 13 is operated by supplying the minimum power necessary for operation while the host computer 3 is powered off.

  53 is a tray discharge switch, and 54 is a tray lock detection switch. The tray discharge switch 53 is provided outside the information storage device 2 and is electrically released from the locked state of the medium loading tray 52 in the information storage device 2 when pressed by the user. By releasing the locked state, the medium stacking tray 52, together with the tray discharge switch 53, stores the information storage by the action of an elastic body such as a spring (not shown) provided between the information storage device 2 and the medium stacking tray 52. It is discharged outside the device 2. The tray lock detection switch 54 is a switch provided inside the apparatus 2 and detects that the medium loading tray 52 is completely pushed into the information storage apparatus 2 and is locked.

  When power is supplied from the power supply device 7 based on the detected switch state or the change in the switch state, the CPU 11 to which the switches 53 and 54 are connected determines the necessary processing and determines the medium. An operation of ejecting the loading tray 52 or an operation of making the removable medium 1 in a recordable / reproducible state is performed.

  For example, in the slim tray loading type information storage device of the third embodiment, the tray lock release device 51 releases the locked state of the medium loading tray 52 in the information storage device 2 by a magnetic drive device such as a plunger. Etc. are common. Further, in the slim tray loading type information storage device 2 described in the third embodiment, as shown in FIG. 12, the removable medium 1 is placed on a turntable on a medium loading tray 52 including a medium reproducing device (not shown). After locking, the user pushes the medium loading tray 52 toward the inside of the information storage device 2 to be in the locked state, and the logical state of the tray lock detection switch 54 changes, whereby the removable medium 1 can be recorded and reproduced. Start the operation to put the state.

Next, details of an actual operation for performing LOAD / EJECT will be described.
First, the operation when power is supplied from the power supply device 7 to the host computer 3 and the main power supply operating unit 9 will be described. When power is supplied to the main power supply operating unit 9, the CPU 11 controls the power supply control device 13 so that the power supply control operation of the power supply device 7 is not performed. For example, an output port from the CPU 11 to the power supply control device 13 is prepared, and if the output state from the CPU 11 is H, the power supply control device 13 may be stopped.

  When the tray discharge switch 53 is pressed in this state, process L in FIG. 13A is executed. In process L, first, it is checked in S1301 whether or not the tray lock detection switch 54 is locked. In the locked state, regardless of whether or not the removable medium 1 is loaded in the information storage device 2, the eject control unit 55 is operated to drive the tray lock releasing device 51 in S1302. The locked state of the medium loading tray 52 is released. Then, the medium loading tray 52 is discharged to the outside of the information storage device 2 by the action of an elastic body such as a spring provided between the medium loading tray 52 and the main body of the information storage device 2. At this time, if the removable medium 1 is rotated by a disk-shaped storage medium, the rotation is stopped and then ejected. If it is a non-disk medium such as a semiconductor memory, necessary processing such as access stop is performed. Of course it is done. At this time, the medium loading tray 52 does not need to be completely discharged to the outside of the information storage device 2. If a certain amount is discharged, the user manually removes the medium loading tray 52 from the information storage device 2. The removable medium 1 can be loaded and removed by pulling it completely out. If the tray discharge switch 53 is pressed and the tray lock detection switch 54 is in the tray unlocked state, no operation is performed. After these processes, in step S1303, the main power supply operating unit 9, that is, the information storage device 2 is set in a standby state. In addition, since the power control device 13 is in a non-operating state after these processes are completed, the power supply by the power supply device 7 is continued in S1304.

  Next, the loading operation will be described. In a state where the medium loading tray 52 is ejected, the user stores information on the medium loading tray 52 in a state where the removable medium 1 is loaded on the medium loading tray 52 or a state where the medium 1 is not loaded. When the medium loading tray 52 is locked by being pushed into the apparatus 2, the process M in FIG. 13B is executed. When the medium loading tray 52 is locked, the tray lock detection switch 54 changes from the unlocked state to the locked state, and the CPU 11 detects this. Next, the presence / absence of the removable medium 1 is detected in S1305. If the removable medium 1 is not placed on the medium loading tray 52, the information storage device 2 is set in a standby state in S1306. The standby state is a state where power is supplied to the main power supply operating unit 9 of the information storage device 2, and the operation of unnecessary circuit blocks inside the information storage device 2 is stopped, so that the necessary power consumption is achieved. That is. At this time, since the power supply control device 13 is in a non-operating state, the power supply of the power supply device 7 is continued in S1307.

  If the removable medium 1 is placed on the medium placing tray 52 in S1305, the recording / reproducing state is set in S1308. For example, in the CD-R / RW recording / reproducing apparatus, the type of the medium 1 is discriminated, the adjustment necessary for the recording / reproducing operation corresponding thereto and the acquisition of the disc information are performed, and the recording / reproducing state is enabled. After that, recording / reproduction of the removable medium 1 is performed in accordance with a command from the host computer 3 in S1309. Even after these processes are completed, since the power supply control device 13 is in a non-operating state, similarly, the power supply by the power supply device 7 is continued in S1307.

  Next, an operation when power is not supplied from the power supply device 7 to the host computer 3 and the main power supply operating unit 9 and power is always supplied from the power supply device 8 to the power control device 13 will be described. When the main power supply operating unit 9 is not supplied with power, the power supply control device 13 is in an operable state.

  When the tray discharge switch 53 is pressed in this state, process N in FIG. 14A is executed. In process N, when the power supply control device 13 detects the pressing of the tray discharge switch 53, the tray lock logic of the tray lock detection switch 54 is detected in S1401. If the tray is locked, in step S1402, the power control device 13 controls the power supply device 7 to start supplying power to the main power supply operating unit 9 and the host computer 3. At this time, in S1403, the power supply control device 13 notifies the CPU 11 that the tray discharge switch 53 has been pressed while the power supply device 7 is stopped. Specifically, for example, the CPU 11 includes a device for accessing a register on the power control device 13, and after the main power supply operating unit 9 is turned on or reset, information on the switch whose state has changed is stored in the register. The power is turned on according to the logical state stored regardless of whether the tray ejection switch 53 is pressed or the logical state of the tray lock detection switch 54 is changed, or the state of either switch is changed. The switch 6 determines whether the power is turned on. The CPU 11 does not operate or performs an ejecting operation depending on the detected power-on factor and the state of the medium loading tray 52.

  When power supply is started by pressing the tray discharge switch 53 and the tray lock detection switch 54 is in the tray lock state, regardless of whether the removable medium 1 is loaded in the information storage device 2 or not. In step S <b> 1404, the ejection control unit 55 is operated to drive the tray lock release device 51 to release the locked state of the medium stacking tray 52. At this time, if the removable medium 1 is rotated by a disk-shaped storage medium, the rotation is stopped and then ejected. If it is a non-disk medium such as a semiconductor memory, necessary processing such as access stop is performed. Of course it is done. Then, the medium loading tray 52 is discharged to the outside of the information storage device 2 by the action of an elastic body such as a spring provided between the medium loading tray 52 and the main body of the information storage device 2. At this time, the medium loading tray 52 does not need to be completely discharged to the outside of the information storage device 2. If a certain amount is discharged, the user manually moves the medium loading tray 52 out of the information storage device 2. The removable medium 1 can be loaded and unloaded completely. After the medium loading tray 52 is ejected, the information storage device 2 is set in a standby state in S1405.

  If the tray lock detection switch 54 is in the tray unlocked state when the tray discharge switch 53 is pressed, the power control device 13 does not perform any operation, and the power supply device 7 also starts power supply. do not do. Of course, in the same manner as when power is being supplied, it is possible to forcibly release the tray lock in consideration of the case where the tray lock detection switch 54 is out of order. In this case, regardless of the logic of the tray lock detection switch 54, the above-described power supply start factor setting, power supply start, ejection, and transition to standby mode are performed.

  Next, in a state where the medium loading tray 52 is ejected, the user places the medium loading tray 52 in a state where the removable medium 1 is loaded on the medium loading tray 52 or in a state where no medium is loaded. The operation when the medium loading tray 52 is changed into the locked state by being pushed into the information storage device 2 will be described. Then, the process O of FIG.14 (b) is performed. That is, when the tray lock detection switch 54 changes from the unlocked state to the locked state and the power supply control device 13 detects this, the power supply device 7 is controlled in step S1407 to control the main power supply operating unit 9 and the host computer 3. Start supplying power to the. At this time, in step S1408, the power supply control device 13 notifies the CPU 11 that the tray lock detection switch 54 has changed from the unlocked state to the locked state while the power supply device 7 is stopped. The main power supply operating unit 9 that has started supplying power detects the presence or absence of the removable medium 1 in step S1409 under the control of the CPU 11. At this time, if the removable medium 1 is not placed on the medium placement tray 52, the information storage device 2 is set in a standby state in S1413. The standby state is a state in which power is supplied to the main power supply operating unit 9 of the information storage device 2, operation of unnecessary circuit blocks inside the information storage device 2 is stopped, and the minimum necessary power consumption is achieved. It is to be. If the removable medium 1 is loaded on the medium loading tray 52, the recording / reproducing state is set in S1410. For example, in the CD-R / RW recording / reproducing apparatus, the type of the medium 1 is discriminated, the adjustment necessary for the recording / reproducing operation corresponding thereto and the acquisition of the disc information are performed, and the recording / reproducing state is enabled.

  Further, it is possible to further control the power supply of the main power supply operating unit 9 and the host computer 3 depending on the factor of the start of power supply and the presence or absence of the removable medium 1. For example, when power supply is started by pressing the tray discharge switch 53 and the medium loading tray 52 is unlocked, or the logical state of the tray lock detection switch 54 changes from the unlocked state to the locked state, When the supply is started and it is detected that the removable medium 1 does not exist, the power supply start factor is reset in S1415, or the information storage device 2 is set in the standby state in S1417 and the power supply is started in S1416. After resetting the factors, in S1406 or S1414, the CPU 11 controls the power supply control device 13 to stop the power supply to the main power supply operating unit 9 and the host computer 3 by the power supply device 7. Thereby, after the tray lock release operation is performed when the tray discharge switch 53 is pressed in the power supply cut-off state, or after the medium loading tray 52 is pushed into the information storage device 2 in the power supply cut-off state, the lock is When the removable medium does not exist even though the state is reached, the main power supply operating unit 9 and the host computer 3 can be powered off.

  If the logical state of the tray lock detection switch 54 is changed from the unlocked state to the locked state and the power supply is started, and the removable medium 1 exists and is in a recordable / reproducible state, the power is turned on in S1411. Data in the removable medium 1 can be reproduced on the host computer 3 and recording processing can be performed by controlling the control device 13 and resetting and canceling the factor information that the power supply is started ( (S1412), the power supply from the power supply device 7 is continued (S1413).

  As in process P of FIG. 15, when there is no change in the state of any switch and the power switch 6 is pressed and power supply is started, both the power supply device 7 and the constant power supply device 8 are switched off from the power-off state. Supply is started (S1501), the information storage device 2 is reset by hardware, and a normal initial operation at power-on is performed. In this initial operation, for example, when the CPU 11 is initialized as described above, the power supply start factor of the power supply control device 13 is checked, and the power supply control device 13 is operated when the power supply start factor is not set. In step S1502, the tray lock detection switch 54 is checked to determine whether the medium loading tray 52 is locked. When the medium loading tray 52 is in the unlocked state, the main power supply operating unit 9 of the information storage device 2 is set in a standby state in S1504. If the medium loading tray 52 is locked, the presence / absence of the removable medium 1 is detected in S1505.

  If the removable medium 1 is not loaded on the medium loading tray 52, the main power supply operating unit 9 is set in a standby state in S1504. When the removable medium 1 is loaded on the medium loading tray 52, the recording / reproducing state is set in S1506. For example, in the CD-R / RW recording / reproducing apparatus, the type of the medium 1 is discriminated, the adjustment necessary for the recording / reproducing operation and the acquisition of the disc information are performed, and the recording / reproducing state is enabled. After that, in S1507, recording / reproduction of the removable medium 1 is performed according to a command from the host computer 3. Even after these processes are completed, since the power supply control device 13 is in a non-operating state, the power supply of the power supply device 7 is similarly continued in S1508.

  The operation when the power is shut off is the same as in the first embodiment, and the power supply of the power supply device 7 is controlled by the control of the power control device 13 or by the operation of the power switch 6 as in the process F of FIG. In any case where the power is shut off, in S509, the inoperable command state of the power supply device 13 from the CPU 11 is canceled, and in S510, the power control device 13 becomes operable.

  In the third embodiment, the case where the operation or inoperability of the power supply control device 13 is performed by the control from the port from the CPU 11 has been described as an example, but the method of monitoring the power supply state of the power supply device 7 by the power supply control device 13 It can be similarly implemented by various methods.

  In the third embodiment, the case where the unlock operation of the medium loading tray 52 is performed by starting the power supply of the main power supply operating unit 9 by the operation of the medium discharge switch 53 has been described as an example. The tray lock release operation using the forced tray lock release mechanism is performed without power supply, and only the operation when the logic of the tray lock detection switch 54 changes from the unlocked state to the locked state is described in the third embodiment. Even in the case of performing by this method, it can be similarly implemented.

  In the third embodiment, when the main power supply operating unit 9 of the information storage device 2 is being supplied with power, the removable medium 1 is not present in the information storage device 2, or the medium loading tray An example has been described in which the information storage device 2 is set to a standby state when 52 is discharged. However, setting the standby state is a general operation of the information storage device 2 and can be similarly performed even when the standby state is not set.

  In the third embodiment, the case where the CPU 11 detects the factor of the start of power supply based on the register information of the power control device 13 is described as an example. However, the power control device 13 detects the tray discharge switch 53 or the tray lock. After detecting the logical change of the switch 54, the terminals connected to the respective switches 53 and 54 are switched to the output terminals so as to maintain the logical state, and the changed logical state is maintained and input to the CPU 11, and further. After using one terminal connected to the CPU 11 to set a logic state (for example, normally when the power is turned on by L and H when the power is turned on) due to a change in the switch state, The power supply is started, such as the one that starts the power supply of the main power supply operating unit 9 and the host computer 3 by controlling the power supply device 7. Factors if possible be notified to the CPU 11, can be implemented similarly not limited.

  As described above, although the power supply control device 13 cannot stop the power supply, it can be realized with a very simple small-scale logic circuit, like a standby or sleep state of a normal information storage device. In comparison with the case where the power supply for each block is cut off inside the IC and only the necessary blocks are supplied with power, the power consumption can be made much smaller.

  Therefore, according to the third embodiment, particularly in the tray loading type information storage device, power is supplied only to the power supply control device 13 while the power supply to the host computer 3 and the main power supply operating unit 9 is stopped. Therefore, the power consumption when the power supply of the entire apparatus is stopped can be minimized, and a change in the pressed state of a plurality of switches provided in the information storage device is detected and power supply is started as necessary. The load / eject operation can be appropriately performed according to the logical state of the switch of the switch, and the power supply device 7 is controlled according to the performed load / eject operation to supply power to the main power supply operating unit 9 and the host computer 3. Since the supply is stopped or continued, the power consumption can be minimized, and after loading, processing according to the contents of the media can be performed automatically. Power supply control method that the information processing apparatus and an information processing apparatus can be provided.

  In FIG. 16, reference numeral 2 denotes an information storage device, which loads the removable medium 1 to reproduce data in the removable medium 1 or record data on the removable medium 1. A host computer 3 is connected to the information storage device 2 by the interface device 4, and sends various operation commands to the information storage device 2 through the interface device 4 or data reproduced by the information storage device 2. Or take action. The interface device 4 generally uses, for example, an interface standardized for communication between a computer and an information storage device, such as ATAPI, SCSI, USB, and IEEE1394. Of course, even if an interface device 4 other than these standards is used, it can be similarly implemented if data and commands can be exchanged between the host computer 3 and the information storage device 2.

  A power supply device 5 is a power supply device 7 that is turned ON / OFF by a power switch 6 and a constant power supply device 8 that always supplies power as long as power is supplied to the power supply device 5 even if the power switch 6 is operated. It consists of. The power supply device 7 supplies power to the host computer 3, the main power supply operating unit 9 in the information storage device 2, and the power supply control device 13. The main power supply operating unit 9 in the information storage device 2 is for operating the main functions of the information storage device 2, and includes a load / eject control unit 10, a CPU 11, a medium transport device 12, a removable medium playback device (not shown), and the like. Is included. The constant power supply device 8 supplies power to the power control device 13 in the information storage device 2. The power supply control device 13 controls the supply and stop of the power supply by the power supply device 7. The power supply control device 13 is always operated from the power supply device 8 while the power supply of the host computer 3 and the main power supply operating unit 9 is shut off. The minimum necessary power is supplied and operating.

  Reference numeral 17 is a medium discharge switch, and 18 is a medium insertion detection switch. The medium discharge switch 17 is provided outside the information storage device 2 and performs a medium discharge operation when pressed by the user. The medium insertion detection switch 18 is provided inside the device 2 and detects that the removable medium 1 has been inserted into the information storage device 2. When power is supplied from the power supply device 7 based on the detected switch state or change in the switch state, the CPU 11 connected to the switch 18 determines necessary processing and performs load / eject control. The unit 10 is operated, and the medium transport device 12 is driven to perform the LOAD / EJECT operation. For example, in the slot loading type information storage device, the medium transport device 12 is configured by a combination of a roller for transporting the medium 1 and a spring or gear for transporting the medium 1.

Next, details of an actual operation for performing LOAD / EJECT will be described.
First, the operation when the power is supplied from the power supply device 7 to the host computer 3 and the main power supply operating unit 9 is the same as the process A in FIG. 3A and the process B in FIG. is there. Next, when the power is not supplied from the power supply device 7 to the host computer 3 and the main power supply operating unit 9 and the power is supplied only to the power supply device 13 by the constant power supply device 8, the medium is discharged. When the switch 17 is pressed, the process C shown in FIG. 4A is executed. In addition, the operation at the time of power-off is the same as the process F in FIG.

  In the following, when power is not supplied from the power supply device 7 to the host computer 3 and the main power supply operating unit 9 and power is supplied only to the power supply device 13 by the constant power supply device 8, The operation when the logic state of the insertion switch 18 changes will be described. In this case, the process DX in FIG. 17 is executed. That is, first, the power supply control device 13 detects that the medium insertion switch 18 has been pressed, and controls the power supply device 7 to supply power to the main power supply operating unit 9 and the host computer 3 in S401. Start. At this time, the power supply control device 13 notifies the CPU 11 that the logic of the medium insertion detection switch 18 has changed while the power supply device 7 is stopped (S402). Specifically, for example, the CPU 11 includes a device that accesses a register on the power supply control device 13, and information on the switch whose state has changed is stored in the register after the main power supply operating unit 9 is turned on or reset. Depending on the logic state, the power is turned on regardless of whether the medium ejection switch 17 is pressed, the logic state of the medium insertion detection switch 18 is changed, or a change in the state of either switch. The switch 6 determines whether the power is turned on.

  When the power is supplied, the CPU 11 detects that the logical state of the medium insertion detection switch 18 has changed while the power supply device 7 is stopped by the notification of the power supply control device 13 in S402, and the removable medium 1 is loaded. The host computer 3 is activated in an instant activation mode for reproducing or processing the recorded data in a predetermined format (S1701). In S407, the load / eject control unit 10 is operated in accordance with the switch logic change of the medium loading sequence on the structure of the information storage device 2 to drive the medium transport device 12, and the removable medium 1 is stored in the information storage device 2. Pull in.

In S1702, it is determined whether or not the removable medium 1 exists in the information storage device 2. If the removable medium 1 exists, the medium 1 is set in a recordable / reproducible state (S408).
In step S1703, it is determined whether data of a predetermined type for instant activation is recorded on the medium 1. If recorded, data reproduction and processing are automatically started (S1704). In S410, the power control device 13 is controlled to reset and cancel the factor information that the power supply is started, so that the power control device 13 becomes inoperable. In the next S411, the main power supply operating unit 9. The power supply of the host computer 3 is continued as it is.

  The following process can be performed when the medium 1 does not exist in the apparatus in S1702 and when a predetermined type of data is not recorded in the medium 1 in S1703. That is, in S1705, the information storage device 2 is set in a standby state, and in S1706, the power supply control device 13 is controlled to reset and release the factor information that the power supply has been started. In the next S1707, power supply to the main power supply operating unit 9 and the host computer 3 is stopped.

  If the predetermined type of data is not recorded on the medium 1 in S1703, the following processing can also be performed. In other words, by controlling the power supply control device 13 in S1708 to reset and cancel the factor information that started the power supply, the power supply control device 13 is made inoperable, and in the next S1709, the host computer is restarted in the normal mode. to start.

  When power supply is started by pressing the power switch 6, activation in the normal mode is performed without performing activation in the instant mode. In this case, as shown in FIG. 18, power supply is started from the state where the power supply device 7 is shut off in S501. As a result, when the information storage device 2 is reset by hardware, a normal initial operation at power-on is performed. In this initial operation, the power supply device 7 starts power supply and then disables the power supply control device 13 (S502). Further, the host computer 3 is activated not in the instant mode but in the normal mode (S1801). Then, it is determined whether or not the removable medium 1 is loaded in the apparatus (S503). If it is loaded, an operation for enabling recording / reproduction is performed (S504), and a command from the host computer 3 is issued if necessary. Thus, the reproduction or recording operation of data in the medium 1 is performed (S505). If not loaded, the information storage device 2 is set in a standby state in S506. Then, the power supply is continued as it is (S507).

  In the case where power is not supplied from the power supply device 7 to the host computer 3 and the main power supply operating unit 9 and power is supplied only to the power control device 13 by the constant power supply device 8 as described above, Even when the discharge switch 17 is pressed, the host computer 3 is temporarily activated. The activation mode at this time may be either the instant mode or the normal mode. In this case, the power supply to the main power supply operating unit 9 and the host computer 3 is stopped after the medium discharging operation regardless of the activation mode.

  According to the fourth embodiment, the present invention can be suitably applied to moving images and audio data such as DVD-Video, Video CD, and CD Audio. Other than this, even if you can start up and play back in instant mode, you can perform the same operation for stop images, slideshow playback of still images, combinations of still images and audio data, video data of different standards, audio data, etc. It is.

  For example, the OS main body is recorded on a hard disk such as Microsoft Windows (registered trademark), and is started in order to expand and start it on the memory of the host computer main body. It can be considered that it takes a relatively long time. For example, an application that is recorded in the main body ROM and can be started up in an instant mode without a dedicated OS for DVD-Video, Video CD, or Audio playback, or a high-speed startup such as an OS for Linux or an embedded device. Is possible.

  When the host computer 3 is activated in the instant mode, the data on the removable medium 1 is automatically reproduced. At that time, by operating the keyboard, mouse and other input devices provided in the host computer 3, it is possible to perform fast forward, pause, stop playback, power-off of the information processing device, restart in the normal mode, and the like. . Of course, the power-off operation can also be performed by the power switch 6 of the information processing apparatus 2.

  The power supply from the constant power supply device 7 is a low-capacity power supply that can always supply power independently of other main body power supplies, such as ATX standard + 5V VSB. Of course, as long as the power supply control device 13 can be operated, a power supply of 3.3 V or any other voltage can be similarly applied.

  In the information processing apparatus and the power supply control method for the information processing apparatus according to the present invention, power is supplied only to the power control device while the power supply to the information storage device and the control device is stopped. The power consumption of the entire device when the power supply is stopped can be minimized, and the change in the pressed state of the switch provided in the information storage device is detected, and the power supply is performed as necessary to switch the logical state of the switch. In accordance with the load / eject operation can be appropriately performed, and further, the power supply device is controlled according to the performed load / eject operation to stop or continue the power supply to the information storage device and the control device. When ejecting, the power consumption is kept to a minimum, and by inserting the medium, the information processing device automatically performs processing according to the contents of the medium after loading. Disk recording and reproducing apparatus, a semiconductor memory media recording and reproducing apparatus is effective as such.
