An engaging mechanism includes a casing, a first engaging member and a second engaging member. The casing has a first engaging recess and a second engaging recess. The first engaging member is slidably disposed in the casing and has a first engaging portion. The second engaging member is rotatably disposed in the casing and has a second engaging portion. When the first engaging member is located at a first lock position, the second engaging member is able to rotate between a second lock position and a second unlock position. When the second engaging member is located at the second unlock position and the first engaging member slides from the first lock position to a first unlock position, the first engaging member pushes the second engaging member to rotate toward the second lock position, such that the second engaging portion blocks the second engaging recess.

Engaging mechanism

A chassis includes a housing, a partition, a movable member and a tray. The housing includes a top plate and a bottom plate, and the top plate is opposite to the bottom plate.

The movable member is connected to the partition. The movable member is configured to move between a first position and a second position. The tray includes a latch member. When the movable member is located at the first position and the tray is placed into the accommodating space, the movable member is embedded into the through hole and the latch member engages with the movable member. When the movable member is located at the second position, the movable member disengages from the through hole.
