Abstract
In a continuous mode, when a state in which a current value, which is output of a load detecting sensor, is equal to or more than a predetermined threshold (a current value) continues for a predetermined threshold (the number of times), it is determined that transportation is abnormal. In a cumulative mode, when the total number of times by which the current value, which is the output of the load detecting sensor, is equal to or more than the predetermined threshold (the current value) is equal to or more than a predetermined threshold, it is determined that the transportation is abnormal. A controller sets a detection mode of a first medium to the continuous mode, and sets a detection mode of a second medium to the cumulative mode.
Claims10
A transport apparatus, comprising:
- a transport mechanism that transports a medium;
- a sensor that detects a load on the transportation of the transport mechanism;
- and
- a processor that receives a result of the detection by the sensor and controls the transportation by the transport mechanism,
- wherein the processor acquires a type of the medium to be transported, and determines whether the transportation is normal or abnormal based on the acquired type of the medium and output of the sensor,
- wherein the processor,
- when the acquired medium is a first medium, if a state in which the output of the sensor is equal to or more than a predetermined threshold continues for a first predetermined number of times or more, determines that the transportation is abnormal, and
- when the acquired medium is a second medium, if the total number of times by which the output of the sensor is equal to or more than the predetermined threshold is equal to or more than a second predetermined number of times, determines that the transportation is abnormal,
- wherein when the sensor outputs a first pattern,
- the processor determines that the transportation is abnormal when the acquired medium is the first medium, and determines that the transportation is not abnormal when the acquired medium is the second medium having a transport length that is shorter than a transport length of the first medium.
