Description

Conveying device and image forming apparatus Technical Field The present invention relates to a conveying device and an image forming apparatus. Background Patent document 1 discloses an automatic document feeder characterized by comprising a conveyance path member including a conveyance path surface constituting a conveyance path for conveying a document in an apparatus main body, one end side of the conveyance path member being rotatably supported by the apparatus main body and being opened when the other end side of the conveyance path member moves in a direction separating from the apparatus main body, a locking member mounted on a rotation shaft provided on the other end side of the conveyance path member, the locking member being biased in a 1 st rotation direction locked to a locked portion of the apparatus main body and being locked to the locked portion so as to hold the conveyance path member in a closed state of the conveyance path, and an operation member rotated by its or a biasing force in a2 nd rotation direction opposite to the 1 nd rotation direction to an operation position when the apparatus main body moves to an exposed position of the conveyance path member, the operation member being mounted with a tolerance in a direction of the rotation shaft, so as to be further locked from the rotation position in the 2 nd rotation direction by a self-weight. Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2013-81147 Disclosure of Invention Problems to be solved by the invention As a conveying device, a conveying device is considered which includes a device main body, an opening/closing portion which is attached to the device main body so as to be openable and closable between a closed position covering an upper surface of the device main body and an open position exposing the upper surface, and which has a conveying path for conveying a target material therein, and a conveying path member which has a conveying path surface constituting a part of the conveying path, one end side of the conveying path member being rotatably supported by the opening/closing portion, and the conveying path being opened when the other end side of the conveying path member moves downward from the opening/closing portion. As this conveying apparatus, there is considered a conveying apparatus including a locking portion rotatably attached to the other end side of the conveying path member, the locking portion holding the conveying path member in a state of closing the conveying path in a locked state of being locked to the locked portion, based on a force of locking the locking portion to a locked portion of the opening/closing portion, that is, a force applied in a1 st rotation direction. In this conveying device, in a non-locked state in which the locked portion is not locked to the locked portion, the operator directly pushes the conveying path member from below to bring the locked portion into contact with the locked portion, and the locked portion rotates in the 2 nd rotation direction opposite to the 1 st rotation direction. In such a conveying device, if the operator does not directly push the conveying path member, the locking portion cannot be rotated in the 2 nd rotation direction. Therefore, it is necessary to perform an operation of closing the opening/closing portion and an operation of rotating the locking portion in the 2 nd rotation direction, respectively. The purpose of the present invention is to enable the movement of an opening/closing part from an opening position to a closing position and the rotation of a locking part in the 2 nd rotation direction by a single operation. Means for solving the problems The invention according to claim 1 is a conveying apparatus comprising an apparatus main body, an opening/closing portion which is attached to the apparatus main body so as to be openable and closable between a closed position covering an upper surface of the apparatus main body and an open position exposing the upper surface, and which has a conveying path for conveying a target material therein, a conveying path member having a conveying path surface constituting a part of the conveying path, one end side of the conveying path member being rotatably supported by the opening/closing portion and being opened when the other end side of the conveying path member is moved downward from the opening/closing portion, and a locking portion which is rotatably attached to the other end side of the conveying path member, based on a force of the locking portion to the opening/closing portion, that is, a force applied in a 1 st rotational direction, the portion holding the conveying path member in a locked state of the member in the locking portion in a state, and rotating the locking portion in a non-locking direction of the first rotational direction, and pushing the locking portion in a state of the locking portion in a non-locking portion of the opening/closi
