Claims

[Claims for Utility Model Registration] A plurality of detection units each consisting of a light emitting unit and a light receiving unit facing each other are arranged in multiple stages along a form conveyance path of a conveyance device through which forms are conveyed,
The jam detection device detects whether the form is conveyed normally by detecting that the form passes between the light emitting part and the light receiving part by the detection part, and the jam detection device starts operating in response to an activation signal; a timer circuit that causes the light emitting section to emit light for a predetermined light emitting time after a predetermined set time; and a timer circuit that causes the light emitting section to emit light for a predetermined light emitting time; a jam determination circuit that outputs an activation signal to a timer circuit of the detection section and outputs a jam signal if the light reception signal from the light emission section does not turn off during the light emission time of the light emission section; Jam detection characterized in that the activation signal of the timer circuit of the detection section is a document conveyance start command signal, and the activation signal of the timer circuits of the detection sections of the other stages is an activation signal output from the jam determination circuit of the previous stage.
