PURPOSE: To obtain a small cassette with built-in memory, the contact points part of which is not exposed, by providing electric terminals inside a positioning hole or a detection hole or an erase preventing hole of the cassette.
CONSTITUTION: The contact points member 7 constituted of a metal is mounted inside the cassette positioning hole 3 on a main body 1 of the cassette. A bar- shaped contact points member 8 and an elastic member 12 such as a spring, etc., are inserted inside the positioning pin 11 of the main body side of an electronic device and vertically movable. When the main body 1 is inserted into the main body of the device, the pin 11 is inserted into the hole 3, then the member 7 is brought into contact with the member 8 at the time when the insertion is completed. Since the member 12 is being mounted on the member 8 at this time, the members 7 and 8 are pressed with a specified pressure, thereby the satisfied contact minimized in contact failure is realized.
