DOCUMENT CONVEYANCE DEVICE AND IMAGE FORMING APPARATUS

摘要

A document conveyance device according to the present disclosure includes a document conveyance path, a first actuator, a second actuator, and an optical sensor. The first actuator is disposed in the document conveyance path. The second actuator is disposed on a more downstream side than the first actuator in the document conveyance path in the document conveyance direction. An output state of the optical sensor is switched based on pivoting of the first actuator and second actuator. A tip end of the document passes the first actuator, whereby the optical sensor outputs a first output indicating a first state, the tip end of the document passes the second actuator, whereby the optical sensor outputs a second output indicating a second state, and a rear end of the document passes the first actuator, whereby the optical sensor outputs the first output.

1. A document conveyance device comprising:
a document conveyance path through which a document passes, a first actuator that is disposed in the document conveyance path and pivots in a predetermined direction by being butted by the document, a second actuator that is disposed on a more downstream side than the first actuator in the document conveyance path in a document conveyance direction and pivots in the predetermined direction by being butted by the document, and an optical sensor whose output state is switched based on the pivoting of the first actuator and second actuator,wherein the optical sensor outputs:
a first output indicating a first state in which the document does not pass the first actuator and the second actuator, the first output in a state in which a tip end of the document passes the first actuator, whereby only the first actuator of the first actuator and second actuator pivots in the predetermined direction, a second output indicating a second state, different from the first state, in which the tip end of the document passes the second actuator, whereby both the first actuator and the second actuator pivot in the predetermined direction, and the first output in a state in which a rear end of the document passes the first actuator, whereby the first actuator pivots in a direction opposite to the predetermined direction and the second actuator pivots in the predetermined direction.
