<p>PROBLEM TO BE SOLVED: To provide a paper conveyance device which detects opening and closing of an operation section provided on a paper conveyance passage property at low cost. SOLUTION: When an operation section 3 is closed, an actuator 21 provided in the operation section 3 brings a projection part 23 formed in a main body case into contact with a receive face 21b of the actuator 21, and a contact end part 21a of the actuator 21 is away from an open and close switch 20 provided on an operation port substrate 6 in the operation section 3 and is in off condition. When the operation section 3 is opened, the projection part 23 leaves the receive face 21b, and the contact end part 21a of the actuator 21 moves in the direction of the open and close switch 20 on the operation port substrate 6 due to its elasticity. The contact end part 21a of the actuator 21 pushes the open and close switch 20 to turn on the open and close switch 20 and detect that the operation section 3 is opened.</p> |
