Latest Patents
Harada holds a patent for a sound dampening impact printer. This invention features a feeding path designed to guide printing paper efficiently through the printer. The cross-sectional shape of the feeding path is minimized to ensure it is just sufficient for the paper to pass through. A key component of this design is the inclusion of at least one resonator within the feeding path. The resonator consists of a case that defines a resonant chamber, with holes formed along the case that communicate with the feeding path. This innovative design effectively silences impact sounds generated by the printer's printing head, particularly at frequencies around the resonant frequency of the resonator. Additionally, the reduced area of the feeding path further contributes to noise reduction.
