Abstract

Opening/closing operation is detected at a portable communication terminal that includes an opening/closing mechanism and upon predicting the occurrence of a shock resulting from at least one of the opening operation and the closing operation, the head of a hard disk drive is retracted to a safe position so as to prevent damage to the disk and the head.

Claims

1. A portable communication terminal, comprising:

a first body unit;

a second body unit;

an opening/closing mechanism used to open/close the first body unit and the second body unit relative to each other;

a hard disk drive at which data written onto a disk by using a head are stored;

a predicting device that detects opening operation/closing operation of the opening/closing mechanism and predicts occurrence of a shock attributable to at least one of the opening operation and the closing operation; and

a control device that retracts the head of the hard disk drive to a safe position so as to ensure that neither the disk nor the head becomes damaged, based upon a prediction of occurrence of shock by the predicting device.

2. A portable communication terminal according to claim 1, wherein:

the predicting device detects the opening operation of the opening/closing mechanism by detecting that the opening/closing mechanism, having been in a closed state, has become opened by a predetermined extent.

3. A portable communication terminal according to claim 1, wherein:

the predicting device detects the closing operation of the opening/closing mechanism by detecting that the opening/closing mechanism, having been in a open state, has become closed by a predetermined extent.

4. A portable communication terminal according to claim 1, wherein:

the opening/closing mechanism is any of;

a mechanism that opens/closes by allowing the first body unit and the second body unit to slide relative to each other, a mechanism that opens/closes by allowing the first body unit and the second body unit to fold relative to each other and a mechanism that opens/closes by allowing the first body unit and the second body unit to twist relative to each other.

5. A portable communication terminal according to claim 1, further comprising:

a state detection device that detects at least one of an open state and a closed state of the opening/closing mechanism, wherein;

the control device sets the head of the hard disk drive at a position at which write to disk is enabled, if the state detection device detects the open state or the closed state of the opening/closing mechanism.

6. A portable communication terminal according to claim 1, further comprising:

a state detection device that detects at least one of an open state and a closed state of the opening/closing mechanism, wherein;

the control device sets the head of the hard disk drive at a position at which read from disk is enabled, if the state detection device detects the open state or the closed state of the opening/closing mechanism.

7. A portable communication terminal according to claim 1, further comprising:

a state detection device that detects at least one of an open state and a closed state of the opening/closing mechanism, wherein;

if the state detection device detects the open state or the closed state at the opening/closing mechanism while the head is held at the safe position, the control device moves the head of the hard disk drive to a position at which a write into the disk is enabled.

8. A portable communication terminal according to claim 1, further comprising:

a state detection device that detects at least one of an open state and a closed state of the opening/closing mechanism, wherein;

if the state detection device detects the open state or the closed state at the opening/closing mechanism while the head is held at the safe position, the control device moves the head of the hard disk drive to a position at which a read from the disk is enabled.

9. A portable communication terminal according to claim 1, wherein:

the predicting device includes a detection device that detects the opening operation/closing operation of the opening/closing mechanism.

10. A portable communication terminal according to claim 9, wherein:

the detection device includes an acceleration sensor.

11. A portable communication terminal according to claim 4, wherein:

the predicting device includes an acceleration sensor;

if the opening/closing mechanism opens/closes as the first body unit and the second body unit are allowed to fold relative to each other, the acceleration sensor is disposed at least at one of an end of the first body unit located on a side opposite from a rotational center of the opening/closing mechanism and an end of the second body unit located on a side opposite from the rotational center of the opening/closing mechanism; and

if the opening/closing mechanism opens/closes as the first body unit and the second body unit are allowed to twist relative to each other, the acceleration sensor is disposed at least at one of an end of the first body unit located on a side opposite from a center of a rotating motion of the opening/closing mechanism and an end of the second body unit located on a side opposite from the center of the rotating motion of the opening/closing mechanism.

12. A portable communication terminal according to claim 1, further comprising:

a switching device that switches a data storage location to an external storage device connected via a wireless communication device based upon a prediction of occurrence of shock by the predicting device.

13. A portable communication terminal according to claim 1, further comprising:

an image-capturing device that captures an image, wherein;

image data obtained by capturing the image at the image-capturing device are stored into the hard disk drive.
