Abstract
If a damper or a magnetic catch is used to make a guide member self-holdable in an opened state, a force is required for holding the weight of the guide member in the opened state. This increases an operation force for closing the guide member and degrades the operability. In contrast, if a mechanical holding mechanism without using the damper is employed, the hold may be disengaged without intention of a user. A sheet conveyance device includes an upper conveyance guide for guiding a conveyed sheet and a holding portion for holding the upper conveyance guide in an opened position with respect to a lower conveyance guide opposed thereto, wherein the upper conveyance guide includes an operation portion for disengaging engagement between the upper conveyance guide and the holding portion, and the holding portion includes an operation portion for disengaging engagement between the upper conveyance guide and the holding portion.
