Connecting structure between electrical connector of sheet feeder and electrical connector of image forming apparatus to be installed onto top of the sheet feeder
An electrical connector of an image forming apparatus exposes outward from a bottom surface of the image forming apparatus. An electrical connector of a sheet feeder protrudes from a top surface of the sheet feeder. The sheet feeder has a slider configured to be horizontally movable, while holding the electrical connector of the sheet feeder, between a connecting position at which the electrical connectors of the sheet feeder and image forming apparatus are connected and a disconnecting position at which the electrical connectors are disconnected. A locking member having a locking engaged part is fixed to the image forming apparatus. When the slider is moved to the connecting position, a locking engaging part of the slider engages the locking engaged part of the locking member so that the locking member and the slider are locked such that they cannot be separated vertically from each other.
1. A connecting structure between an electrical connector of a sheet feeder and an electrical connector of an image forming apparatus to be installed onto a top of the sheet feeder,
the electrical connector of the image forming apparatus being arranged to expose outward from a bottom surface of the image forming apparatus,
the electrical connector of the sheet feeder being arranged to protrude from a top surface of the sheet feeder,
the sheet feeder having a slider configured to be horizontally movable, while holding the electrical connector of the sheet feeder, between a connecting position at which the electrical connector of the sheet feeder is connected to the electrical connector of the image forming apparatus and a disconnecting position which is spaced from the connecting position and at which the electrical connector of the sheet feeder and the electrical connector of the image forming apparatus are disconnected,
the image forming apparatus having fixed thereto a locking member having a locking engaged part,
the slider having provided thereon a locking engaging part configured to be engageable with the locking engaged part,
wherein:
when the slider is at the connecting position, the locking engaging part of the slider engages with the locking engaged part of the locking member to lock the locking member and the slider such that the locking member and the slider cannot be separated vertically from each other; and
when the slider is at the disconnecting position, the locking engaging part of the slider and the locking engaged part of the locking member are disengaged to unlock the slider and the locking member.
2. The connecting structure of claim 1 , wherein the slider has a handle configured to able to be hand-gripped and the slider is configured to be movable between the connecting position and the disconnecting position through a manual operation using the handle.
3. The connecting structure of claim 2 , wherein:
the sheet feeder has a box member covering the slider; and
the handle is configured to be switchable between a usable state in which the handle protrudes out of the box member and a folded state in which the handle is housed in the box member.
4. The connecting structure of claim 1 , wherein:
the locking member has a cylindrical part and has a groove as the locking engaged portion, the groove being formed in a peripheral surface of the cylindrical part to surround an axis of the cylindrical part;
the slider has a through hole having an elongated hole shape, the through hole penetrating the slider vertically and being elongated in a moving direction of the slider; and
the though hole is configured such that when the slider is at the disconnecting position, the locking member is allowed to pass through the through hole vertically, and when the slider is moved to the connecting position from the disconnecting position, an edge of the through hole engages the groove to function as the locking engaging part.
5. The connecting structure of claim 4 , wherein:
the through hole has a large-diameter elongated hole part and a small-diameter hole part, the large-diameter elongated hole part being elongated in the moving direction of the slider and allowing vertical movement of the locking member, the small-diameter hole part connecting to one end in a longitudinal direction of the large-diameter elongated hole part and having a diameter smaller than a diameter of the large-diameter elongated hole part; and
an edge of the small-diameter hole part functions as the locking engaging part.
