The present invention relates to a reducer () comprising: a hollow input shaft () having a driving surface () therein; an output shaft () which is accommodated inside the input shaft () and having an output shaft body () having an output shaft gear () formed along the circumferential direction on the outer surface; a plurality of rollers (R) aligned between the output shaft () and the driving surface () and extending in the axial direction; and ring-shaped caps () positioned on both sides of the axial direction of the rollers (R), wherein the rollers (R) are guided to move in the radial direction by means of the caps () and, when the input shaft () rotates, the rollers (R) are pressurized against the driving surface () to pressurize the output shaft gear (), so that the output shaft () rotates.

Reducer

Proposed is a combo antenna module which laminates a loop coil and an antenna sheet to configure a combo antenna, thereby preventing the degree of design freedom from being lowered and minimizing the manufacturing cost. The proposed combo antenna module includes a magnetic sheet, a loop coil disposed on the upper surface of the magnetic sheet, and an antenna sheet having the area smaller than that of the magnetic sheet, and disposed on the upper surface of the magnetic sheet, in which the antenna sheet overlaps a part of the loop coil.

Combo antenna module

Provided is an antenna module in which magnetic sheets are disposed on one surface and the other surface of an antenna sheet having a plurality of radiation patterns formed thereon, and an overlapping area between the magnetic sheets is formed to maximize antenna performance for electronic payment, short-range communication, and wireless charging. The provided antenna module comprises: the antenna sheet having radiation patterns formed thereon; a first magnetic sheet disposed on one side of the antenna sheet; and a second magnetic sheet disposed on the other side of the antenna sheet, wherein the first magnetic sheet and the second magnetic sheet form an overlapping area.
