Claims (1)

[Scope of utility model registration request] A capture means for capturing contact input information at each predetermined timing, a plurality of storage means for storing contact input information of a plurality of preceding times, contact input information stored in each storage means, and a capture means. a comparison means for comparing each input contact input information;
A contact whose preceding contact input information other than the most preceding contact input information from the comparing means is equal to the contact input information captured by the capturing means, and whose most preceding contact input information is captured by the capturing means. 1. A contact input state detection device comprising: a state change signal generating means that receives a discrimination signal indicating that the contact input information is different from the input information and outputs a signal indicating that the contact input information has changed.
