  • Publication number: 20210062838
    Abstract: A joint mechanism includes a first route member and a second route member. The first route member includes; a first pivot point disposed in a first apparatus, which forms a portion of a transport route opposite a first surface of a sheet; and a first pivot section that extends from the first pivot point toward a second apparatus and that has a first abutment member. The second route member includes: a second pivot point disposed in the second apparatus, which forms a portion of the transport route opposite a second surface of the sheet; and a second pivot section that extends from the second pivot point toward the first apparatus and that has a second abutment member. The first abutment member abuts against the second route member and the second abutment member abuts against the first route member to maintain a space to transport the sheet.
