  • the projection 17 may be employed three or more in number, in which case, by increasing the number of the combinations of presence or absence thereof, a number of installation holders 3 can be identified.
  • the type of the automotive vehicle can be recognized. Since depending on the type of automotive vehicle the site, at which the installation holder 3 is fitted, may vary and it may occur that the installation angle thereof may also vary, by correcting an acceleration data from the acceleration sensor 5 within the device main body 2 for each type of the automotive vehicle the driving behavior may require correction, but when as a result of identification of the holder 3 the installation angle of the device is known, the correction of the acceleration data become easy to accomplish. Accordingly, the type of the installation holder 3 can be recognized for each type and, therefore, the driving behavior appropriate to the type of the particular type of the automotive vehicle can be easily corrected.
  • Fig. 5 illustrates a block diagram showing the drive diagnosing device 1 designed in accordance with another preferred embodiment of the present invention. While in the practice of the previously described first embodiment of the present invention, the contact type lever switch is used and is made operable concurrently for the holder identification and for the mounting detection, in the practice of the second embodiment the concurrent use of the lever switch for the holder identification and for the mounting detection is eliminated and, instead thereof, the holder identification is provided separate from the device detection.
