Abstract: DIN rail installation kit including main body, spring hook, latch fastener and elastic element and combined with electronic device. When latch fastener is pulled down first to move to second position, buckle of latch fastener pushes down on hook body of spring hook, and after passing under hook body, hook end of hook body can be temporarily positioned on side wall of latch fastener. When user releases latch fastener, elastic element returns latch fastener, buckle is then buckled on buckle portion of hook body, and second buckle means of latch fastener is kept away from first buckle means of main body to present a removable state. When latch fastener is pulled down secondarily to return to first position, buckle is separated from buckle portion of hook body, and second buckle means and first buckle means are relatively buckled on DIN rail to exhibit a state of tight coupling.

Abstract: A multi-function peripheral having an automatic document feeding device (ADF) suited for being configured in a body of an apparatus is provided. The apparatus has a first and second power sources to drive the ADF to transmit a paper in or out of the body. The ADF includes a limiting structure, a swinging member and a blocking member. The first and second power sources drive the limiting structure and the swinging member to swing respectively. The blocking member has a first end connected to the swinging member and a second end extending toward the limiting structure. When the limiting structure is at a second position and the swinging member swings toward a third position, the second end is trapped into the limiting space. When the limiting structure moves toward a first position and the swinging member swings toward the third position, the second end escapes from the limiting space.

Abstract: A paper-feeding device and a multi-function printer (MFP) using the paper-feeding device are provided. The MFP includes a housing with the paper-feeding device installed thereon. The paper-feeding device includes an outer case, an inner case and a retainer. The outer case has first side-walls, openings and slots, in which each opening and each slot on the opening are correspondingly disposed on each first side-wall. The inner case is located beside the first side-walls of the outer case and has a second side-wall. The second side-wall has a position-limiting rib protruding towards the first side-walls. The retainer is located between the first side-walls and has a body, a protrusion and a pivot, in which the protrusion is disposed at a top-portion of the body and correspondingly located in the slots, and the pivot is located between the protrusion and a retaining-portion of the body and correspondingly locked in the openings.
