Description of the Related Art [0004] In general, a medium processing apparatus for handling paper media such as banknotes or checks includes a deposit / withdrawal unit, which is a space in which a customer inserts or receives a medium for deposit / withdrawal, a conveyance path through which a deposit / A temporary storage unit for temporarily storing the deposited medium after passing through the discriminating unit, a medium stored by the customer is stored, and the stored medium is withdrawn, And the like.

In recent years, it has become common to arrange a plurality of cassettes in the lower unit and a module to perform various functions for processing the medium in the upper unit, as the type of the medium to be handled becomes various, and the processing capacity of the medium increases. The cassette is housed in a safe to enhance the safety of the medium.

Therefore, the upper unit is disposed on the safe, the conveying path connecting the plurality of cassettes and the conveying path is accommodated in the safe as a lower unit, and a connection conveying path for conveying the medium between the upper unit and the lower unit is installed in the opening of the upper portion of the safe Thereby performing deposit and withdrawal of the medium.

In recent years, as the thickness of the safe increases to increase the security, the medium passing through the upper part of the safe is held by the conveying roller provided in the connecting conveying path by providing the connecting conveying path in the opening of the upper part of the safe. So that it can be returned to.

The upper unit and the lower unit are constructed so as to be capable of being housed in one side from the main body of the media processing apparatus. When a jam occurs in the medium at the connecting portion between the upper unit or the lower unit and the connecting and conveying path, The operation of the processing apparatus is stopped and an operator takes out the upper unit or the lower unit to the outside of the main body to perform maintenance work such as removal of the medium.

However, even if the upper unit or the lower unit is pulled out from the main body, the medium may remain in the connected conveyance path, and in this case, there is a problem that it becomes difficult to remove the medium. As one example of prior art for solving such a problem, Japanese Patent Application Laid-Open No. 2002-163704 discloses a method in which a pair of open / close guides provided on a conveying path connecting portion of a connecting conveying path are opened by a draw- It is known to prevent tearing or breakage of the medium at a portion of the substrate.

However, when the medium is left over the conveying path and the connecting conveying path of the unit only by providing such open / close guides, one end and the other end of the medium are sandwiched by the different conveying paths, There is a fear that the residual medium may be pulled from both sides and torn, so that it is difficult to easily remove the residual medium in the connection conveying path without breakage.

On the other hand, when a plurality of cassettes are provided in the lower unit, a driving gear for transmitting the driving force of the motor and a power transmission gear are connected to the conveying path connecting portion between the upper unit and the connecting conveying path, .

In this case, when the upper unit is pulled out or pulled out from the main body, interference may occur between the plurality of driving gears and the power transmission gears, so that the upper unit can be smoothly drawn out A gear arrangement structure between the conveying paths is required.
