An electronic device is provided. The electronic device includes a housing, a first printed circuit board seated inside the housing, and a second printed circuit board seated inside the housing such that a height of the second printed circuit board from the second surface is different from that of the first printed circuit board, wherein the first printed circuit board includes a mounting part on which at least one component is mounted, a first connector which extends from a first part of the mounting part. A portion of the first connector being substantially perpendicular to the mounting part and configured to be connected to the second printed circuit board, and a second connector which extends from a second part of the mounting part and configured to be connected to the second printed circuit board.

A reciprocating compressor includes a piston reciprocating in a chamber. A valve plate disposed at one end of the chamber includes a fluid inlet orifice and a fluid discharge orifice. Each orifice is covered by a valve in the form of a resilient material check valve arranged so that a free end thereof covers the respective orifice. Each valve comprises a resilient material check valve anchored at an end opposite its free end. Each valve includes a cut-out forming a resilient portion pressed against the valve plate for pre-biasing the valve to an open position.

An oil pickup structure of a compressor is constituted by a lubricant supplying apparatus of the tube type placed somewhat slantly at the end of the crank shaft, in which the tube has the cross-section with the same size throughout its over all length, at least one means for separating the refrigerating gas from the tube and discharging therefrom, and a projecting member mounted at the middle portion of the tube with being spaced away from said gas separating/discharging means so as to reduce the noise by the lubricant.
