Abstract
The number n of times of chewing is counted by chewing number of times calculation means () based on a change in the distance l from a photoreflector (), which is received together with time t by measurement value receiving means (). To vary hardness h of a bag () to a stage that can be sensed, according to the number n of times of chewing, a required air pressure is set according to the current number n of times, based on a hardness/air pressure correspondence recording unit () in which stages that have a significant difference therebetween and are stored in association with the number n of times of chewing are recorded. To realize the set air pressure inside the bag (), the amount of sucking performed using a vacuum pumpis controlled by air pressure control means ().
