Abstract
A small size apparatus for measuring and recording acceleration comprises an acceleration sensor, an A/D converter which converts the output signal of the acceleration sensor to a digital signal, a control element which processes the digital signal, a detachable external memory device which stores data of a change in acceleration and, a battery for supplying electric power to the sensor, the A/D converter, the control element and the external memory device. The small size apparatus is mounted on a moving body to be measured and the entire small size apparatus is driven by the battery. The correct attachment of the external memory device is detected by steps of writing data into a special address, reading the data out thereafter, and comparing the written data and read data. When the read data coincides with the written data, it is judged that the external memory device is correctly attached.
