   BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to a cash transaction machine, and more particularly, to a withdrawal apparatus in which cash is withdrawn at the front surface or rear surface of a cash transaction machine. 
   2. Description of the Related Art 
   A cash transaction machine is an automation apparatus which can support a basic banking service such as depositing or withdrawing cash without a bank staff, regardless of place or time, with respect o financial service. The cash transaction machine may be divided into a cash dispenser and an automated teller machine according to whether cash is paid into or withdrawn and used for not only depositing or withdrawing cashes but also depositing or withdrawing checks, arranging bankbooks, and selling tickets. 
   Now, using the cash transaction machine is gradually increased in banks or other financial agency. Gradually, customers frequently use the cash transaction machine according that using the cash transaction machine becomes convenient. As increase of frequency of using the cash transaction machine, the amount of each banking transaction is increased together. According to the increase of the amount dealt via the cash transaction machine, a lot of notes are paid into or withdrawn. According to using the lot of notes, there are frequently generated unexpected matters due to movement or position interference between notes. 
     FIG. 1  is a perspective view of a conventional cash transaction machine. 
   Referring to  FIG. 1 , a cash transaction machine is an apparatus for depositing or withdrawing cashes or checks, in which several modules divided into function units, such as a magnetic card reading module, a bankbook arrangement module, a user interface module, and a note deposit/withdrawal module, are installed in a housing. 
   The magnetic card reading module is exposed outside via a card insertion part  10 , and the user interface module is exposed outside via a display screen  20  or a key input part  25 . 
   The note withdrawal module is exposed outside via a cash discharge part  30 . The cash discharge part  30  is according to a direct discharge type, in which previously requested amount of cash is prepared in the note withdrawal module and the cash is provided as a stack from the cash discharge part  30 . 
   In the front insertion type, the position of inserting the cassette is the same as the direction of the withdrawal part. In case that the front surface of a cash transaction machine is opened and closed, a withdrawal apparatus of the front insertion type is used. 
   In the rear insertion type, the position of inserting the cassette is opposite to the direction of the withdrawal part. In case that the rear surface of a cash transaction machine is opened and closed, a withdrawal apparatus of the rear insertion type is used. 
   Accordingly, in case that the cash cassette is changed, the front insertion type has to be used in the withdrawal apparatus of a cash transaction machine whose front surface is opened and closed and the rear insertion type has to be used in the withdrawal apparatus of a cash transaction machine whose rear surface is opened and closed. 
   SUMMARY OF THE INVENTION 
   To solve the described problems, the present invention provides a withdrawal apparatus capable of freely inserting paper media such as cash into the front surface or the rear surface of a cash transaction machine without regard of an opening and closing method of the cash transaction machine. 
   According to an aspect of the present invention, a withdrawal apparatus of a cash transaction machine includes a first transfer element and a second transfer element which are separated from each other, and a temporary stack part moves between the first transfer element and the second transfer element to function as a part of the second transfer element. For example, the temporary stack part may be located at an end portion of the first transfer element and receive paper media sheet by sheet from a storage. When a requested amount of the paper media is loaded, the temporary stack part moves to the second transfer element and locates a stack of the paper media on a transfer path of the second transfer element. The second transfer element may start to operate and transfer the paper media stack to a withdrawal part. 
   The transfer path is defined by the first transfer element and second transfer element. The first transfer element transfers the paper media from the storage to the temporary stack part, and the second transfer element transfers the paper media stack transferred by the temporary stack part to a withdrawal extension part. Generally, the first and second transfer elements move in one direction. 
   Also, the second transfer element includes an upper transfer part and a lower transfer part. The upper transfer part is provided above the transfer path to define its upper boundary, and includes upper rollers disposed at the both ends thereof and an upper rotation transfer belt passing through the upper rollers and rotating. The lower transfer part is provided below the transfer path to define its lower boundary. The upper transfer part is integrated in a body, while the lower transfer part may be integrated in a body or separated to form two or more bodies, such that the lower transfer part may provide an entry space for the temporary stack part. The lower transfer part includes lower rollers provided below the transfer path and at least one lower rotation transfer belt passing through the lower rollers and rotating the path except the entry space. 
   The lower transfer part may be longer than the upper transfer part to be projected from the both ends of the upper transfer part as the same length. Thus the second transfer element may have a symmetrical structure, and its symmetrical structure may be advantageously applied to the position change of a withdrawal extension part. 
   Also, converting the withdrawal apparatus into a front insertion type or a rear insertion type may be easily performed by using the first and second transfer element. Generally, a cassette is used for storing and inserting the paper media. In the front insertion type, the position of inserting the cassette is the same as the direction of the withdrawal part. In case that the front surface of a cash transaction machine is opened and closed, a withdrawal apparatus of the front insertion type is used. In the rear insertion type, the position of inserting the cassette is opposite to the direction of the withdrawal part. In case that the rear surface of a cash transaction machine is opened and closed, a withdrawal apparatus of the rear insertion type is used. In the withdrawal apparatus according to the present invention, the position of inserting the cassette is fixed, the position of the withdrawal part may changed by switching the rotation direction of the second transfer element. The change is possible because the first transfer element is separated from the second transfer element. The procedure of switching may be simply performed. 
   In this case, the withdrawal apparatus includes the function of withdrawal, and both of a module for only withdrawing and a module for deposit/withdrawal may be understood as the withdrawal apparatus. Also, the paper media transacted by the withdrawal apparatus is an article in a shape of a sheet, which has a certain value, such as notes, checks, gift certificates, and tickets. The paper media may be formed of a material that may be substitute for paper, such as a plastic thin film, in addition to paper.
