摘要： PROBLEM TO BE SOLVED: To provide an information portable terminal which can maintain the security of information even if an ID card is stolen or a password is known by deleting information on a storage device in information portable terminal equipment when the information portable terminal is taken out to a place out of a limited area where the information portable terminal is used. SOLUTION: A CPU 19 reads a self-identification code which is previously stored in a ROM 20 through an inner bus 18 and transmits identification code information which is read to a PHS radio base station. When the self- identification code is not returned from the PHS radio base station and an access counter is counted for not less than N, information in a RAM 21 is deleted. When the information portable terminal 100 cannot communicate with the PHS radio base station even if it tries not less than N times, it is judged that information portable terminal equipment 100 is taken out to a place out of an area that the PHS radio base station covers. Information in the RAM 21 in the information portable terminal 100 is deleted and a warning sound is issued.

摘要： PURPOSE:To reduce a power consumption by decreasing the basic frequency of an information processor according to a surrounding brightness. CONSTITUTION:A photodetector 1 detects a light made incident through a light receiving part 22, and outputs an electric signal corresponding to the surrounding brightness. Then, it is transmitted through an amplifier 2, and compared with a reference level by a comparator 3. A basic frequency from an oscillator 4 is frequency-divided by a frequency devider 5 according to the output of the comparator 3, and outputted as the basic frequency of a CPU. When a display screen 21 is closed, the light is not made incident to the light receiving part 22, and the basic frequency is frequency-divided and reduced. Thus, the power consumption of the CPU can be reduced.

摘要： PROBLEM TO BE SOLVED: To solve a problem that an incoming sound continuously rings although a user is absent when an incoming call arrives at a telephone set if the user leaves a seat after placing the telephone set on one's telephone set, that it is necessary to set and release a manner mode and an automatic answering mode by a manual operation and therefore it often occurs that setting and release are forgotten and that private information is possibly viewed by a third person at one's discretion when the user is absent if private information on an individual is stored in one's telephone set. SOLUTION: The telephone set 100 transmits a radio wave to a small unit 200 when the incoming call arrives and switches a system to ring the incoming sound or to the automatic answering mode according to whether the radio wave is to be received from the small unit 200 or not. The telephone set transmits the radio wave to the small unit at the time of an input operation and selects whether the function of the telephone set is to be suppressed or not according to whether the radio wave is to be received from the small unit or not.

摘要： PROBLEM TO BE SOLVED: To provide an AC adapter supporting device by which an AC adapter of a type different from a dedicated AC adapter can be used and an electronic appliance system using the same. SOLUTION: When the AC adapter is connected to one of plural DC jacks 11 of different types for inserting the plug of the AC adapter, a polarity detecting/switching circuit 9 detects the polarity of the output voltage of the connected AC adapter and when the polarity is unsuitable to the supply of power to an electronic appliance main body 1, the circuit 9 switches the polarity. A voltage detection circuit 8 discriminates whether the output voltage of the connected AC adapter is within a range allowable for supplying power to the main body 1 and discriminates whether the maximum allowable value of the output current of the connected AC adapter, which is detected by loading by a pseudo loading circuit 7, is sufficient to operate the main body, 1. When it is judged that the output voltage of the connected AC adapter is within the allowable range and that the output current has the sufficient value, power is supplied to the main body from the AC adapter.

摘要： PROBLEM TO BE SOLVED: To obtain an AC/DC adapter which can deal with a plurality of electronic apparatus having different maximum output value and output system by controlling the output of an electronic apparatus based on the decision results of the maximum output value and output system of the electronic apparatus. SOLUTION: An electronic apparatus 5 comprises a memory 7 storing the maximum output, value and an AC/DC adapter 1 comprises a circuit 3 for controlling the electronic apparatus 5 based on the maximum output and the output system thereof read out from a memory 7 upon connection with the electronic apparatus 5. Consequently, two or more electronic apparatus having different maximum output value and output system can be dealt with one AC/DC adapter and the cost and time required for developing an AC/DC adapter for each type of electronic apparatus can be curtailed. Furthermore, an AC/DC adapter taken out from an electronic apparatus can be connected with another electronic apparatus having a different maximum output value and used at all times.
