Abstract: To calculate a moving distance with high accuracy based on an acceleration acquired from an acceleration sensor. A mobile information terminal 1 performs gravity correction processing for an acceleration acquired from an acceleration sensor 18 to remove a gravitational acceleration component, calculates a distance by performing integration processing twice, and calculates a moving distance from extracted start and end points as compression depth. The mobile information terminal 1 notifies a rescuer who is performing cardiac massage of the compression depth in the immediately preceding compression operation so as to allow him or her to perform the cardiac massage with an adequate compression depth.

Abstract: A CD player includes a device main body, a blind panel that covers the front surface panel side of the device main body, an operating part for operating the device main body, a display part for displaying the contents of an operation, and a blind panel moving and operating mechanism for moving the blind panel between a shield position where the front surface panel side is shielded and an operative position where the front surface panel side is exposed and the operating part can be used. The operating part is arranged on a surface opposed to the front surface panel of the device main body in the shield position of the blind panel, and the display part is arranged on the front surface panel of the device main body. The size of the operating part and the size of the display part are enlarged to improve an operability and a viewability of the display part.
