Abstract: An electronic apparatus includes: a memory for storing voice data of an operation explanation related to a function of the electronic apparatus; a speaker for outputting operation explanatory voice based upon the voice data stored in the memory; a push-button for instructing an execution of the function with respect to the electronic apparatus; and a control unit for turning ON, or flickering the push-button when the operation explanatory voice is being outputted from the speaker.

Abstract: A constant speed driving apparatus comprises a starting means for starting a control unit, the first pulse-generating means for generating the first pulse signal with a predetermined frequency, a driving mechanism for driving a load, the second pulse-generating means for generating the second pulse signal corresponding to driving speed of the driving mechanism, and the control unit for controlling the driving mechanism on the basis of the first and second pulse signals.

Abstract: An autofocus camera has a photographing lens, a shutter normally urged in a shutter opening direction and arranged to be opened and closed after it has once been closed prior to a photographing operation, a mirror movable between a view position which allows light passing through the lens and the shutter to be transmitted to a viewfinder optical system and an exposure position which allows light passing through the photographing lens and the shutter to be transmitted to the surface of a film, and an automatic focus adjustment apparatus for automatically adjusting the position of the lens.

Abstract: A control device for a small press is provided with means preventing overloading of the drive motor, a timer for detecting when an operational cycle of the press has exceeded a normal value, and a position detector which notes the position of a cam of the press. The power switch of the drive motor is tripped to suspend the flow of current to the motor upon an indication of the foregoing, e.g., a detected over-current, an excessive cycle time, or an operation end position of the cam.
