An optical module apparatus equipped with a latch coupler includes a carrier movable on a guiding rod. The guiding rod is coupled with a turnable check member. When the optical module apparatus is on a flat and using position, the check member may pass through a check trough to enable the carrier to move freely and linearly and reciprocally. When the optical module apparatus is mounted in an inclined manner and moved away from the using position, the check member is subject to the gravity force and turns in parallel with the direction of the gravity force, and is latched on the check trough to restrict the moving range of the carrier. Thus the optical module apparatus may be prevented from moving by external forces during transportation and avoid being damaged.
