Claims (1)

[Scope of claim for utility model registration] (1) In addition to containing the main body of the information recording and reproducing device,
an outer box having an insertion/removal port for inserting and removing a cartridge case containing a recording medium; and an outer box rotatably attached to the inside of the outer box, and the cartridge case is inserted into the outer box. a first door that opens the insertion/ejection port when the cartridge case comes into contact with the cartridge case; a second door for opening and closing the insertion/ejection opening; and a second door provided in the outer box for moving the second door to close the insertion/ejection opening when the cartridge case is inserted in the outer box. An information recording and reproducing device comprising: a means of transportation; (2) The second door has an opening/closing part that protrudes from both ends of the lower edge to open and close the insertion/ejection opening, and a sliding part that is integrally formed with this opening/closing part. The moving means is a T-shaped plate made of , an L-shaped mounting bracket with its base end attached to the lower part of both ends inside the insertion/removal opening, and an L-shaped mounting bracket with its base end attached to the distal end of the mounting bracket so as to be rotatable about the middle part, and one end A lever that is in contact with the abutment part and whose other end is pushed down by the cartridge case and rotated to push up the second door, and whose upper end is fixed to the lower end of the second door. 2. The information recording and reproducing device according to claim 1, further comprising a spring whose lower end is fixed on the inner surface of the outer box and has a restoring force to pull down the second door.
