Latest Patents
One of Manabe's latest patents is the "Ink ribbon cassette for printer." This invention features an ink roller made of plastic sponge that is impregnated with ink, along with an endless type ink ribbon that contacts the ink roller. The design includes a leaf spring member that maintains proper tension on the ink ribbon. During assembly, the pressure from the leaf spring is not applied until the ribbon is set. Once in place, the bow-shaped leaf spring is reversed, creating a snap action that applies the necessary tension. Additionally, as the ink volume in the ribbon decreases over time, the spring member applies pressure to the ink roller, allowing for ink transfer and extending the ribbon's service life.
Another significant invention is the "Audiovisual card reproducing device." This device allows users to insert an audiovisual card into a cabinet, enabling visual information on the card's upper surface to be viewed through a window. Simultaneously, audio information recorded on a disk mounted on the card's undersurface can be reproduced. The device includes mechanisms for correctly locating and holding the card in position, as well as preventive measures to avoid damage to the program groove of the disk-record and stylus during ejection or accidental removal.
