Abstract

PURPOSE: To provide a jam detecting apparatus for duplicator or the like, in which a first and a second detectors for detecting passing of a travelling material are provided along the passage of the travelling material, and a timer is connected respectively to these detectors, whereby jamming of the travelling material can be detected in reliable manner also at the time when the material transporting speed is changed.
CONSTITUTION: At the inlet and the outlet of drying and fixing section of a duplicator, there are provided a first and a second detecting means 1, 2, each consisting of a light emitting element and a light receiving element, which produce an output when it is detected that travelling material 3 such as paper sheet is passing through the inlet and the outlet of the drying and fixing section in the direction of arrow shown in the drawing. Timers 5, 7 are reset when the output from the detectors 1, 2 is extinguished and determine their set time in association with pape (3) transporting speed. Output of detector 1 is supplied to timer 5 and also to one input terminal of AND-circuit 6, whereas output of timer 5 is supplied to the other input terminal of the circuit 6. Further, output of the detectors 1, 2 is supplied via an OR-circuit to AND-circuit 12, to control control circuit 15 for heater 4
