To easily and previously predict how many pieces of films can be stored even when a piece film having very different length is coexistently stored by providing a holding part holding the piece film for every piece film and receiving the piece film from the side of the long side of the holding part.

A holding case 21 is provided with plural storage chambers 23 functioning as the holding parts separated from each other by a horizontal partition wall 22. The storage chambers 23 are juxtaposed in a perpendicular direction and hold the piece film 2 one by one. Each of the chambers 23 has a wide aperture part for receiving 23a which can receive six frames of pictures for the side of the long side. Thus, the piece films 2 as many as the chambers 23 are stored regardless of the length of the piece film 2, so that the number of the piece films 2 which can be stored in one film magazine 10a does not differ in accordance with the length of each piece film 2.
