Body weight displayer for increase and decrease of body weight

摘要

PURPOSE: A scale for displaying variation in weight is provided to manage the weight of a user effectively by displaying the variation in weight immediately through numerical value per specific period or graphs, and to promote convenience in use of plural people by automatically discriminating a user to be measured even though plural people uses the same scale. CONSTITUTION: Each unit of a scale is powered on by a power supply(12) and a CPU(Central Processing Unit,8) is operated to convert analog value of weight into digital value in an ADC(Analog to Digital Converter,7) when a user steps on a weight sensor(6). The CPU displays a name or an ID(Identification) number of the user on a displayer(9) by selecting the proximate data of the user from a database of a memory(10) if the converted digital value is set regularly. If plural values of proximate data exist, plural names or ID numbers of plural individuals are displayed on the displayer. The plural names and ID numbers are checked by the user through a key(13) and recorded on each corresponding database. Date data is read out of a clock(11) and then recorded on the memory. The weight data of the selected date are displayed by numerical value or graphs on the display unit. When the user comes down from the scale, the CPU controls the power supply not to feed power any longer. If the user wants to check the weight changes without getting on the weight sensor, the user selects the own data mode with the key and checks the weight data of numerical value or graph type through the displayer.
