Topic As for this device it is possible to implement the prevention of simultaneous interposition of the multiple memory curd, it designates that it offers as purpose.Solutions As for this device the memorandum Ricardo reader encloses no type thing memory curd in regard to the memorandum Ricardo reader which can implement the prevention of simultaneous interposition of the multiple memory curd, has with the group of electric conduction terminal groups which are jointed insulating itself and with the memory curd which 2 possess the enclosing vessel of the memory curd at least. In addition, the spring piece which can prevent the simultaneous interposition of the multiple memory curd is set to the contiguity enclosing vessel to the reader. It is constituted from 3 parts of the contact section where the spring piece, was formed from the elasticity arm and the elasticity arm which are extended from the attaching part and the attaching part which are containment to insulating itself also is pushed to one contiguity enclosing vessel little. When a kind of memory curd is interposed in the enclosing vessel, the contact section deformation the elasticity arm to be pushed, occur in the elasticity arm, to rush by the contiguity enclosing vessel, the other memory curd becomes interposition impossible.
