Abstract

Provided is an electronic device such as a storage apparatus coping with, with a simple configuration, a situation where data transfer cannot be performed because of an occurrence of an abnormality in the connection using a connector or the like, at the time of occurrence of a shock due to an earthquake or the like.
The present invention is applied to an electronic device in which a drive that stores data and a control board having disposed thereon a controller that controls data transfer between the drive and another apparatus are connected via a connector. The electronic device includes: an acceleration sensor; and a vibration sensing processing section that controls a state of communication between the drive and the controller to temporarily stop data transfer performed by the drive, for a period during which a possibility of occurrence of an ongoing abnormality exists in the connection using the connector or the like, when the acceleration sensor has sensed an acceleration of exceeding an upper-limit threshold, and causes the temporarily stopped data transfer to resume when the acceleration sensor has sensed an acceleration of equal to or lower than a lower-limit threshold.

First claim

What is claimed is:

1 . An electronic device in which a drive that stores data and a control board having disposed thereon a controller that controls data transfer between the drive and another apparatus are connected to each other via a connector, the electronic device comprising:
an acceleration sensor that senses occurrence of a vibration; and a vibration sensing processing section that controls a state of communication between the drive and the controller to temporarily stop data transfer performed by the drive, when the acceleration sensor has sensed an acceleration exceeding an upper-limit threshold, and causes the temporarily stopped data transfer to resume when the acceleration sensor has sensed an acceleration of equal to or lower than a lower-limit threshold.

2 . The electronic device according to claim 1 , wherein
the vibration sensing processing section causes the controller to change the state of communication with the drive from a normal state to a data transfer stopped state, and to change the state of communication with the drive to the normal state at a time of resumption.

3 . The electronic device according to claim 2 , wherein,
during the data transfer stopped state, a memory disposed on the control board accumulates data being transferred, and, after the resumption of the temporarily stopped data transfer, the data accumulated in the memory is transferred to the drive.

4 . The electronic device according to claim 3 , wherein
the electronic device is stopped when it has become impossible for the memory to accumulate data.

5 . The electronic device according to claim 1 , wherein
the drive and the control board are mounted on a backboard attached to a housing, and the acceleration sensor is disposed on the backboard.

6 . The electronic device according to claim 1 , wherein
the drive and the control board are mounted on a backboard attached to a housing, and further, part of the control board is attached to the housing by a screw, and the acceleration sensor is disposed near a portion where the screw is attached on the control board.

7 . The electronic device according to claim 1 , wherein
the vibration sensing processing section allows the upper-limit threshold and the lower-limit threshold to be modified.

8 . An electronic device control method applied to an electronic device in which a drive that stores data and a control board having disposed thereon a controller that controls data transfer between the drive and another apparatus are connected to each other via a connector, the electronic device control method comprising:
a temporary stop process of temporarily stopping data transfer performed by the drive, when an acceleration sensed by an acceleration sensor that senses occurrence of a vibration exceeds an upper-limit threshold; and, after the temporary stop process, a resumption process of causing the temporarily stopped data transfer to resume when the acceleration sensor has sensed an acceleration of equal to or lower than a lower-limit threshold.
