Abstract: An original-position confirming device adaptable to a relatively large sized copying machine is disclosed. The device comprises a transparent base plate which is supported on a platform of a copying machine and a pair of cylindrical lamps changable between two kinds of light intensity. During a mode for confirming the position of a desired original image, the lamps are moved to a desired position suitable for confirming the original image therethrough by manipulating manual operation switches. During a mode for copying the original, the lamps traverse the original at a predetermined rate.An operator can easily confirm the position of the original image to be copied by referring to a measuring scale provided on the platform.

Abstract: A method and apparatus for reproducing a desired portion of letters and/or patterns in an original on a copying paper, wherein the system is computerized so as to obtain the necessary information from the data stored with respect to the distance components derived from the original, and on the basis of the information, an area excluding the desired portion of the original is deelectrified so as to exclude the area from the expected reproduction of the desired portion on the copying paper.

Abstract: An electrically operated, hand-held tier for tying a length of fishline to a fishhook comprises a tying wheel mounted rotatably on a bearing boss for rotation in one direction. The tying wheel has an anchoring member secured thereto for holding releaseably one end portion of the fishline after the fishline has been passed through the bearing boss. One end of a fishhook opposite to its sharp point is adapted to be received in coaxial relation to the bearing boss and has a number of turns of the fishline formed thereon when the tying wheel is rotated several times thereabout. The rotation of the tying wheel is effective to form a knot on the fishline which is necessary to secure the fishhook to the fishline.

Abstract: An electric fishing float in which a cell used as a power source is an elongated cylindrical cell having an electrode axially upwardly extended from the top of the cell and with the shell of the cell serving as another or opposite electrode in order to turn on a light source such as a light emitting diode or miniature lamp positioned within an elongated float body adjacent the closed top end thereof.
