Abstract
Abstract An electronic apparatus includes power source for supplying a power, key input unit for inputting key instructions, a memory for memorizing the key instructions, a generator for generating a power off cancel instruction to be invalidated the power-off of the power supplied from the power source in response to at least one of the key instructions or at least one of the memorized instructions memorized by the memory, a detector for detecting the output of the power off cancel instruction generator, and a controller for controlling the power source in response to the output of the detector.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
91 words
A method for controlling power supply to an electronic apparatus wherein memory contents are erased upon a power-off, comprising the steps performed by said electronic apparatus, subsequent to a power-off operation resultant from octuation of a power switch, of: generating an instruction for inhibiting a switch-off of the power to said electronic apparatus after the power-off operation; detecting the inhibiting instruction developed by the step of generating; and controlling the power supply to continue supply of power to said electronic apparatus in response to the detected output of said inhibiting instruction.
Claim 2
Independent Claim
91 words
A method for controlling power supply to an electronic apparatus wherein memory contents are erased upon a power-off, comprising the steps performed by said electronic apparatus, subsequent to a power-off operation resultant from octuation of a power switch, of: generating an instruction for inhibiting a switch-off of the power to said electronic apparatus after the power-off operation; detecting the inhibiting instruction developed by the step of generating; and controlling the power supply to continue supply of power to said electronic apparatus in response to the detected output of said inhibiting instruction.
Claim 3
Dependent Claim
18 words
The method of claim 1 wherein said instruction for inhibiting is introduced into said device by an operator.
