Abstract

A portable physical checker which is provided with a display part, a group of the function changing-over keys and ten-keys for data input on the surface of the unit case where is sufficiently thinner than dimensions of height and width thereof and has the electrodes for measuring inner body impedance at reverse side of the above unit case, the central processing unit processes according to the input from above electrodes based on the setting with the above function changing-over keys and keys for data input and also the memory unit for data storage.

Claims

1. A card type physical checker comprising:

a case;

said case having a thickness substantially thinner than its height and width;

a rear face of said case;

a pair of electrodes provided as said rear face for measuring inner body impedance;

a front face of said case provided opposite said pair of electrodes, said front face having a display part;

key pad means for inputting basic physiological data; and

a group of function changing keys for selecting one of a plurality of desired operation modes, said selected operation mode adapted to accept data of measured body impedance from said pair of electrodes;

a central processing means positioned within said case for processing signals inputted from said electrodes and data inputted from said key pad in accordance with said one selected operation mode for determining body fat corresponding to said inner body impedance; and

a memory unit positioned within said case for storing data based on said signals inputted from said pair of electrodes and said data inputted from said key pad in said selected operation mode.
