CONSTITUTION:When a jacket body 1 is inserted to the holder part on the side of a magnetic recording and reproducing device, a projecting piece 35 to be the first projecting part is inserted into a guide groove 28, and its tip corner part 35A is moved along a slope 25 of a lock piece 22 to press a projecting part 30 into the jacket body 1 against the elastic force, and a pawl part 24 and a tip 21a of a detaining piece 21 are disengaged from each other. A tip edge 35A of the projecting piece 35 is brought into contact with the tip 21a of the detaining piece 21 to open window parts 12 and 13 gradually. When window parts 12 and 13 reach opening terminal positions, a pawl 36 to be the second projecting part drops to a notched recessed part 34 of a connection plate 17 and is engaged with its one side part. When the jacket body 1 is pulled out from the holder part, a cover body 14 is held between the projecting piece 35 and the pawl 36, and in this state, windows 12 and 13 are closed gradually.
