         6 . The medium transport device according to  claim 5 , wherein
 the first processing is processing of punching the medium and   the second processing is processing of binding the medium.   
     
     
         7 . The medium transport device according to  claim 1 , wherein
 the operation portion is attachable and detachable.   
     
     
         8 . A recording system comprising:
 the medium transport device according to  claim 1 ; and   the recording device including the recording unit configured to perform recording on the medium, wherein   a drive source is provided at the recording device.   
     
     
         9 . The recording system according to  claim 8 , further comprising
 a first path forming member attachable to and detachable from a device main body including the first discharge path, wherein   the first discharge path is formed by attaching the first path forming member to the device main body.   
     
     
         10 . The recording system according to  claim 9 , wherein
 the recording device includes an opening/closing body provided openably and closably with respect to the device main body, the opening/closing body being configured to be opened when the first path forming member is attached or detached, and   the operation unit is exposed by opening the opening/closing body.   
     
     
         11 . The recording system according to  claim 8 , wherein
 the recording unit is positioned below the transport unit and   the transport unit includes a holding unit configured to hold foreign matter generated in a transport path through which the medium is transported.   
     
     
         12 . The recording system according to  claim 8 , wherein
 the recording unit performs recording by ejecting a liquid onto the medium.   
     
     
         13 . A recording system comprising:
 the medium transport device according to  claim 2 ; and   the recording device including the recording unit configured to perform recording on the medium, wherein   the recording device includes an opening/closing body provided openably and closably with respect to a device main body including the first discharge path, the opening/closing body being configured to be opened when the first discharge path is accessed,   the operation unit is exposed by opening the opening/closing body,   the medium is fed into the first discharge path by inputting the operating force to the input unit,   the switching unit includes a pressed portion configured to be pressed by the opening/closing body,   when the opening/closing body is in a closed state, the switching unit is in the decoupled state as a result of the pressed portion being pressed by the opening/closing body, and   when the opening/closing body is in an open state, the switching unit is in the transmission state as a result of the pressed portion not being pressed by the opening/closing body.
