  • Patent number: 7900916
    Abstract: The first aspect of the present invention is a paper sheet transport mechanism. This mechanism comprises a first paper sheet guide that forms a first paper sheet transport path, the first paper sheet guide having a rotating shaft; a pushing unit that pushes the first paper sheet guide in a specified direction around the rotating shaft; a projecting member that moves in conjunction with movement of the first paper sheet guide; a second paper sheet guide that forms a second paper sheet transport path such that paper sheets are transferred between the first and second paper sheet guides; and a alignment unit that moves in conjunction with a retune movement of the second paper sheet guide to be in contact with the projecting member against the pushing by the pushing unit and to align one end of the first paper sheet guide and one end of the second paper sheet guide.

  • Patent number: 7276099
    Abstract: An object of the present invention is to provide an electric vacuum cleaner equipped with a compact and easy-to-operate cyclonic separation type dust collector. To accomplish the object, the present invention mounts a cyclonic separation cylinder (104) that centrifugally separates and captures dust and a dust collecting case (105) that contains a first auxiliary filter (106) detachably on the lower case (101) of the cleaner body (1) and part of air from the cyclonic separation cylinder (104) is fed to the motor-driven blower through the dust collecting case (105). The present invention mounts a cyclonic separation cylinder (104) that centrifugally separates and captures dust and a dust collecting case (105) that contains a first auxiliary filter (106) detachably on the lower case (101) of the cleaner body (1) and part of air from the cyclonic separation cylinder (104) is fed to the motor-driven blower through the dust collecting case (105) and a filter provided under it.

  • Patent number: 7207083
    Abstract: The electric vacuum cleaner is disclosed which includes a main body within which an electric blower and cyclonic separation cylinder are provided. A dust collecting case is provided in communication with the cyclonic separation cylinder to receive dust that has been separated from the inlet tube. The dust collecting case also includes a lifter arranged therein. Air received from the inlet tube is separated such that a portion is passed through the dust collecting case and a communicating passage. The air is subsequently merged and discharge through the electric blower.
