<p>A built-in gyrosensor (31) is attached to the rear of a rotary plate (33), which is attached to an attachment hole (24) formed in a side plate of the case of a car navigation system (21) in such a way that the gyrosensor (31) can rotate in a pitch axis direction around one axis. With this constitution, even if the main part of the navigation system (21) is mounted not horizontally with respect to the car body as shown in the Fig. 8, the attaching angle of the built-in gyrosensor (31) can be adjusted horizontally with respect to the car body by turning the rotary plate (33). For that purpose, it is preferable to print an angle scale, or a car model name on the outside face of the rotary plate (33) to indicate the angle to be turned.</p> |
