Abstract: An acceleration device can prevent abnormal acceleration of a vehicle even when an accelerator pedal is erroneously abnormally stepped on instead of a brake pedal, and alert a driver of occurrence of erroneously stepping on the accelerator pedal. Assuming that a driver erroneously steps on an accelerator pedal hard instead of a brake pedal, a magnet of a fixation part of a transmission/blocking mechanism and a magnetic opposing surface of a movable part are disengaged and separated from each other. Accordingly, movement of the accelerator pedal with respect to an accelerator lever is blocked, and the accelerator lever is returned to an idling state due to the action of the accelerator mechanism. Also, an impact and sound of the disengagement of the magnet is transmitted to the driver, and the foot takes a position different from a normal position. Accordingly, the driver can notice erroneous stepping on the accelerator pedal.

Abstract: A projection type image display apparatus (1) comprises a focus correction system (30). The system includes a temperature detection mechanism (16) for measuring temperature in the vicinity of a projection lens group (13), a correction amount calculation unit (18) for calculating a correction amount for correcting the focus shift caused by a temperature change, and a driving signal generation unit (19) for generating, based on the correction amount, a driving signal for driving a focus adjustment mechanism (15). If the user performs a focus adjustment using a focus operation input unit (23), a focus operation determination unit (21) determines that a focus adjustment has occurred independently of the focus correction system and changes a correction condition stored in a memory (20).
