Sheet conveyance device and image forming apparatus

A sheet conveyance device comprising:

• a first guide member configured to guide a conveyed sheet, the first guide member comprising a first operation member provided to be movable with respect to the guide member, the first sheet guide member being provided to be pivotable with respect to a second sheet guide member;
• and
• a holding member configured to be engageable with the first guide member to hold the first sheet guide member a first position, wherein the holding member includes a first member and a second operation member provided to be movable with respect to the first member,
• wherein the first operation member comprises a first engaged portion,
• wherein the second operation member comprises a first engaging portion configured to engage with the first engaged portion of the first operation member,
• wherein the holding member holds the first guide member by engagement between the first engaged portion and the first engaging portion, and
• wherein the engagement between the first engaged portion and the first engaging portion is disengaged by moving the first operation member in a first direction (F), and moving the second operation member in a second direction (E) that is different from the first direction (F).

A sheet conveyance device comprising:

• a first guide member configured to guide a conveyed sheet, the first guide member comprising a first operation member provided to be movable with respect to the first sheet guide member, the first sheet guide member being provided to be pivotable with respect to a second sheet guide member;
• and
• a holding member configured to be engageable with the first guide member to hold the first sheet guide member at a first position, wherein the holding member includes a first member and a second operation member provided to be movable with respect to the first member,
• wherein in the case that the first sheet guide member is at the first position, movement of the first operation member in a first direction and movement of the second operation member in a second different direction disengage the first guide member and the holding member such that the first sheet guide member such that it is moveable from the first position to a second position, and
• wherein the first guide member and the holding member remain engaged in the case that only one of the first operation member and the second operation member is moved in its respective direction.

An image forming apparatus comprising:

• an image forming unit configured to form an image on a sheet;
• and
• a sheet conveyance device configured to convey a sheet,
• wherein the sheet conveyance device includes:

• the first member comprises a first engaging portion configured to engage with the first engaged portion, and
• the second operation member comprises a second engaging portion configured to engage with the second engaged portion, and
• wherein the holding member holds the first guide member by engagement between the first engaged portion and the first engaging portion and engagement between the second engaged portion and the second engaging portion,
• the engagement between the first engaged portion and the first engaging portion is disengaged by moving the first operation member in a first direction, and
• the engagement between the second engaged portion and the second engaging portion is disengaged by moving the second operation member in a second direction that is different from the first direction.
