PURPOSE:To improve usefulness preventing false alarms by displaying detected weight of food and cooking time obtained from the weight of food and by giving out information when a weight display does not continue for a certain space of time. CONSTITUTION:While detecting weight of food when a scale is still reeling right after food is placed on the scale, two registers not shown contained in a micro-computer 12 are compared and if they are different, the signal of R7 becomes high closing a transistor 18, lighting a light emitting diode 16 and an alarm 17 gives out a sound. If the two registers agree repeatedly, the signal at R7 becomes low and the light emitting diode 16 is turned off and the sound 17 is cut off. A time conversion key 14 is operated in this condition. This improves usefulness making accurate alarming. |
