SCRAPPED DOCUMENT STORAGE BOX

PROBLEM TO BE SOLVED: To prevent document from being discharged by providing an inner door normally closing a putting-in passage communicating to the interior of a storage box main body and opening the charging passage in a cover part through a link mechanism interlocking with opening/operation of a putting-in port door. SOLUTION: An inner door opening/closing mechanism is provided with an inner door 22 covering the rear end opening of a guide frame 20 capably of being opened/ closed, and the one end is with a bracket 23 fixed to the upper frame, the other end is with the inner door 22, respectively connected so as to normally energize the inner door 22 to the closed position, The shaft 17 of a putting-in port door 18 is interlocked with the inner door 22 through first and second link plates 25, 26, and when a document is pushed in the putting-in port door and the door is rotationally moved inside, the shaft 17 is rotationally moved so as to move the second link plate 26. The lower closing face of the inner door 22 is opened at the rear end of the guide frame 20, and the document is fallingly put into a main body part. The one end side of the second link plate 26 is connected to the first link plate 25, and the other end side is connected to the rear part of the side frame 18. Hereby, the scrapped document can be put in the main body, and hence theft prevention can be insured.
