Patent ID: 8167305

Claim:
A transporting device comprising: a transporting unit that sequentially transports a plurality of transport media arranged in line in a transport direction; a plurality of medium sensing units that are disposed along the transport direction and that sense the presence/absence of each of the transport media; an encoder that outputs an encoder signal corresponding to an amount of driving for the transporting unit driven to transport each of the transport media; a paper management module that counts the encoder signal output from the encoder for each of the transport media to acquire a count value and that manages a transport status of each of the transport media; a determining unit that, when the count value for the encoder signal reaches a set value set for each of the medium sensing units and it is determined that the medium sensing unit has not sensed the transport medium, determines that a transport error has occurred in the transport medium; a transport controller that, when the determining unit determines that the transport error has occurred in the transport medium and there is a previous transport medium ahead of the transport medium, controls the transporting unit such that the transporting unit continues transporting the previous transport medium; and an error signaling unit that signals a location of occurrence of the transport error, wherein the paper management module stops counting up when the determining unit determines that the transport error has occurred in the transport medium, wherein the determining unit determines the location of occurrence of the transport error from the count value for the encoder signal at the time the paper management module stops counting up, and wherein the error signaling unit signals the location of occurrence of the transport error determined by the determining unit.
