Description

  The present invention relates to a medium processing apparatus such as a banknote cassette or a reject cassette for storing a medium such as a banknote, and an automatic transaction apparatus such as an automatic teller machine including the same.

A banknote cassette provided in a conventional automatic teller machine has a rectangular parallelepiped housing formed of two members including a front cover and a rear cover, and forms a storage space for storing banknotes therein. (For example, refer to Patent Document 1).
Some of the reject cassettes of the automatic teller machine have the same configuration as the banknote cassette 15 (see, for example, Patent Document 2).

Japanese Patent Laying-Open No. 2015-215790 (paragraph 0042, FIGS. 5 and 7) JP 2014-218353 A (paragraph 0193-paragraph 0194, FIG. 2)

In the conventional technology described above, a front cassette and a rear cover, which are two box-shaped members, one of which is opened, are assembled to form a housing for the reject cassette.
Normally, when assembling the front cover 62 and the rear cover 63 that form the housing 61 of the reject cassette, the mounting portion 64 of the front cover 62 is inserted into the inner surface side of the rear cover 63 as shown in FIG. After the combination, the door 65 provided with the lock is opened, the screw 66 is inserted into the through hole provided in the mounting portion 64 of the front cover 62, and is screwed into the screw hole provided in the rear cover 63. The door 67 is locked with a key after tightening with a driver 67.

  With this locking, the stored banknotes cannot be touched by anyone other than the owner of the key that normally unlocks the door.

There is a case where a force is applied to move in a direction opposite to each other (see arrows Z1 and Z2 shown in FIG. 11).

  At this time, since the screw 66 is screwed into the screw hole of the rear cover 63, the screw 66 moves in the same direction as the rear cover 63, and the mounting portion 64 of the front cover 62 to which the screw 66 is tightened is attached to the screw seat surface. It moves in the opposite direction while being pressed.

  For this reason, the screw 66 may loosen due to frictional force during sliding when the screw seat surface of the screw 66 and the mounting portion 64 move in different directions, and the front cover 62 is detached from the rear cover 63. In some cases, security problems may occur.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide means for preventing loosening of a screw when the front cover and the rear cover are fastened with screws.

  In order to solve the above problems, the present invention provides a medium processing apparatus comprising: a first cover that forms a part of an internal space that stores a medium; and a second cover that forms a remaining part of the internal space. The first cover is opposed to the screw fixing portion between a screw fixing portion for screwing a screw for fastening the first cover and the second cover with a predetermined gap. A screw seat surface receiving portion that comes into contact with a screw seat surface when the screw is tightened, and the second cover is inserted into the predetermined gap and provided with a hole through which the screw is inserted. It is characterized by having.

  As a result, the present invention can avoid the loosening of the screw by avoiding the sliding between the mounting portion and the screw seat surface of the screw.
