Patent ID: 8005347

Claim:
A recording/reproducing device that records or reproduces information, comprising: a hard disc drive that records the information; a display section; a power supply that supplies an electric power to the hard disc drive so as to bring the recording/reproducing device into an operating state; a power supply button that gives instructions for turning on and disconnecting the power supply; a drop sensor that detects a drop of the recording/reproducing device; a time counting section that counts a total drop time from a time at which the drop sensor detects the drop of the recording/reproducing device to a time at which the drop stops based on a drop detected signal from the drop sensor; a power supply control section that, when the time counting section counts a predetermined time or more for which the recording/reproducing device drops, controls the power supply so that the electric power to be supplied to the hard disc drive is forcibly disconnected and the recording/reproducing device is brought into an inoperable state; a memory; a writing section that, when the power supply control section forcibly disconnects the electric power to be supplied to the hard disc drive, writes into the memory a flag representing that the electric power is forcibly disconnected and data about the drop including the total drop time or a drop distance calculated based on the total drop time; and a display control section that, when the power supply button is pressed down by a user's operation to turn on the power supply and the flag is written into the memory, controls the display section so that information showing that the power supply is disconnected due to the drop of the recording/reproducing device is displayed thereon, wherein when the recording/reproducing device continues to drop after the electric power to be supplied to the hard disc drive is disconnected, the time counting section counts the total drop time including a drop time after the electric power is disconnected.
