IMPACT MEMORY UNIT

PURPOSE:To miniaturize and lighten a sensor box and to obtain the arrangement improving impact reproducibility and good impact response by incorporating an impact data operational memory means and an impact sensor in respectively separate boxes. CONSTITUTION:An impact memory unit is constituted of a sensor module box 2 having an impact sensor incorporated therein, a processing module box 1 having an operational memory means and a power supply built therein and the signal transmission medium 3 between both boxes. The box 2 is arranged at a position capable of detecting the actual impact of a product to be fed with good reproducibility and the box 1 is arranged at an arbitrary position spaced apart from said box 2 and both of them are connected in a signaling manner by the medium 3. By this method, the sensor module box 2 is made small-sized and light to improve impact response and the impact applied to the product to be fed can be picked up with good reproducibility.
