Patent attributes
A tray mechanism for accommodating an electronic device in a casing having first and second side plates includes a sheet, a pin, a lock rod, a push rod, a tray having a bottom plate and third and fourth side plates, and a fixing plate disposed on the bottom plate. The pin is disposed on the sheet and is movable on the fixing plate. The lock rod and the push rod are slidably arranged on the fixing plate. The pin penetrates through a slot of the lock rod. A hook of the push rod releasably hooks the pin. When a block of the second side plate biases the push rod to separate the hook from the pin, the push rod pushes the pin to slide upward to retract the lock rod inwardly to separate an abutting end of the lock rod from a holding sheet of the first side plate.
