Cover unit including a lock mechanism

摘要

A cover unit includes a cover element for a chamber of a chassis, rotatably supported at one end of the opening and a lock mechanism to lock the cover element in the chassis. The lock mechanism includes a lock element movable in parallel between a lock position and a release position, and having a latch portion to protrude from the cover element at the lock position, an elastic element to press the lock element to the lock position, a hole to receive the latch portion protruding from the cover element and restrict a movement of the latch portion, a receive element to hold the lock element in the release position against the elastic element, and a protrusion to press the receive element when the cover element is pressed onto the opening. The receive element releases the lock element from the release position, when pressed in the orthogonal direction.

主权项

1. A cover unit of an electronic device that includes an image sensor, the cover unit comprising:
a cover element to enclose an opening of a chamber of a chassis, rotatably supported at one end of the opening around an axis set at the one end; and a lock mechanism to lock the cover element in the chassis while the cover element is pressed onto an edge of the opening, the lock mechanism including a lock element contained in the cover element and movable in parallel between a lock position and a release position, and having a latch portion to protrude from the cover element at the lock position, an elastic element provided in the cover element to press the lock element to the lock position, a hole provided in the chassis, to receive the latch portion protruding from the cover element and restrict a movement of the latch portion in a direction orthogonal to a front surface of the cover element, a receive element provided in the cover element, to hold the lock element in the release position against an elastic force of the elastic element, and a protrusion provided in the chamber, to protrude in the orthogonal direction to press the receive element when the cover element is pressed onto the edge of the opening, wherein the receive element is configured to release the lock element from the release position, when pressed by the protrusion in the orthogonal direction by rotating the cover element around the axis set at the one end.
