Abstract: In a stamp apparatus, a paper-sheet object is conveyed in the arrow direction between a presser roller and an impress hub having a predetermined character/symbol string. Since a cam is rotated in the arrow direction by a rotary solenoid, it makes the presser roller approach the impress hub via a roller and an arm. A separating lever is rotated in the arrow direction by a rotary solenoid from an initial position (position shown in the drawing) to a siding position. When the paper-sheet object is conveyed to between the presser roller and the impress hub, a stamp bonded on the bottom surface of the paper-sheet object is canceled with a postmark. A presser mechanism suppresses a rebound produced when the presser roller starts to urge the paper-sheet object, and also maintains a predetermined urging pressure of the presser roller relative to the paper-sheet object having a predetermined thickness or less.

Abstract: A polyurethane foam is used in combination with an ink tray having a housing having a first and second chamber. The first chamber has an overflow baffle extending laterally within said chamber to divide the first chamber into an inlet side and an outlet side. An inlet port is provided for receiving replenishing ink in the inlet side of the chamber and an outlet port is provided for removal of excess ink from said ink tray. A plurality of portals extending between the first and second chambers for directing replenishing ink to the second chamber from the inlet side of the first chamber and excess replenishing ink from the second chamber to the outlet side of the first chamber. An elongated inking roller is mounted to the housing. The absorption material is mounted in the second chamber to contact the replenishing ink. The absorption material has a portion extending from the second chamber and contacting the inking roller to allow the transfer of replenishing ink to the inking roller.

Abstract: An ink tray includes a housing having a first, second and third chamber. The first chamber has an overflow baffle extending laterally within said chamber to divide the first chamber into an inlet side and an outlet side. An inlet port extends into the first chamber for receiving replenishing ink in the inlet side of the chamber and an outlet port is provided for removal of excess ink from said ink tray. A plurality of portals extending between the first and second chambers for directing replenishing ink to the second chamber from the inlet side of the first chamber and excess replenishing ink from the second chamber to the outlet side of the first chamber. An elongated inking roller is rotatively mounted in the third chamber. The third chamber is configured to expose a longitudinal portion of said inking roller. Absorption material is mounted in the second chamber to contact the replenishing ink.

Abstract: Apparatus for affecting positional adjustment of a machine member has an adjustment screw nonrotatably connected to the machine member and screwed into a nut formed as a worm wheel. The worm wheel, meshes with a worm, connected by a worm shaft to an actuator assembly for rotating the worm. The worm shaft is rotatably and axially displaceably mounted in a housing in which the worm wheel is rotatably mounted and the worm shaft is rotatably and axially non-displaceably mounted in a slider, which is guided in the housing for movement in the axial direction of the worm shaft. The slider is reciprocable by a fluid-operable piston-cylinder unit to an extent which corresponds to the desired adjustment of the screw.
