Information Processing Apparatus and Power Supply Control Method for Information Processing Apparatus

An information processing apparatus comprising:

• an information storage device in which a loading/ejection mechanism for a removable medium is operated according to a change in a depressed state of a switch;
• a control device which records data on the removable medium and/or reads out data from the removable medium by controlling the information storage device;
• a power supply device capable of performing and stopping power supply to the information storage device and to the control device;
• a continuous power supply device capable of supplying power when power supply by the power supply device is stopped;
• a power switch with which power supply to the power supply device is started and stopped, and with which, at the time of starting power supply, the control device is started up in a normal startup mode in which general-purpose processing can be performed by a user program executed on an OS;
• and
• a power supply controller which operates by being supplied with power from the continuous power supply device, and which, when the depressed state of a switch provided on an outer portion or an inner portion of the information storage device is changed during stoppage of power supply from the power supply device to the information storage device, controls the power supply device so that the power supply device supplies power to the information storage device or to the information storage device and the control device, thereafter starts up the control device in an instant startup mode for reproducing or processing data in a predetermined format recorded on the removable medium, and controls the information storage device so that the removable medium loading/ejection mechanism is operated according to the change in the depressed state of the switch.

A power supply control method for an information processing apparatus having an information storage device in which a loading/ejection mechanism for a removable medium is operated according to a change in a depressed state of a switch,

• a control device which records data on the removable medium and/or reads out data from the removable medium by controlling the information storage device;
• a power supply device capable of performing and stopping power supply to the information storage device and to the control device;
• and
• a continuous power supply device capable of supplying power when power supply by the power supply device is stopped, the method comprising, when the depressed state of the switch is changed during stoppage of power supply from the power supply device to the information storage device, controlling the information storage device so that the removable medium loading/ejection mechanism is operated, by controlling, by means of a power supply controller which operates by being supplied with power from the continuous power supply device, the power supply device so that the power supply device supplies power to the information storage device or to the information storage device and the control device.

A power supply control method for an information processing apparatus having an information storage device in which a loading/ejection mechanism for a removable medium is operated according to a change in a depressed state of a switch;

• a control device which records data on the removable medium and/or reads out data from the removable medium by controlling the information storage device;
• a power supply device capable of performing and stopping power supply to the information storage device and to the control device;
• a power switch with which start-stop control of power supply by the power supply device is performed;
• a continuous power supply device capable of supplying power when power supply by the power supply device is stopped, and
• a power supply controller which operates by being supplied with power from the continuous power supply device, the method comprising:
• in the case of staring power supply from the power supply device by control with the power switch, starting up the control device in a normal startup mode in which general-purpose processing can be performed by a user program executed on an OS;
• when the depressed state of the switch is changed during stoppage of power supply from the power supply device to the information storage device, controlling by the power supply controller the power supply device so that the power supply device supplies power to the information storage device or to the information storage device and the control device, and starting up the control device in an instant startup mode for reproducing or processing data in a predetermined format recorded on the removable medium;
• and
• controlling the information storage device under a command from the power supply controller so that the removable medium loading/ejection mechanism is operated according to the depressed state of the switch.

An information storage device in which a loading/ejection mechanism for a removable medium is operated according to a change in a depressed state of a switch, comprising:

• a control device for controlling the information storage device so as to record data on the removable medium and/or read out data from the removable medium,
• a power supply device connected to the information storage device and being capable of performing and stopping power supply to the information storage device and to the control device, and
• a power switch for starting and stopping power supply by the power supply device,
• the power switch starting up the control device in a normal startup mode in which general-purpose processing can be performed by a user program executed on an OS upon start of power supply, wherein
• the information storage device further comprises a power supply controller which operates by being supplied with power from a continuous power supply device capable of supplying power even when power supply by the power supply device is stopped, and which, when the depressed state of a switch provided on an outer portion or an inner portion of the information storage device is changed during stoppage of power supply from the power supply device to the information storage device, controls the power supply device so that the power supply device supplies power to the information storage device or to the information storage device and the control device, thereafter starts up the control device in an instant startup mode for reproducing or processing data in a predetermined format recorded on the removable medium, and controls the information storage device so that the removable medium loading/ejection mechanism is operated according to the change in the depressed state of the switch.
