Abstract: The present invention provides a cylindrical printing blanket comprising a seamless sleeve and a sheet-like blanket having a fabric layer, a compressive layer and a surface printing layer, said sheet-like blanket being bonded onto the outer surface of said seamless sleeve. The blanket is made by cutting a long sheet-like blanket that has the fabric layer, the compressive layer and the surface printing layer and is bonded to the outer surface of the seamless sleeve, thus the operation can be done with good workability.

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 printer for printing characters on a recording medium includes, a printing drum provided on a first portion and a second portion of the outer periphery thereof respectively with a first set of type faces and a second set of type faces, the first set of type faces being adapted to print characters of odd or even digit positions in a row of characters to be printed while the second set of type faces is adapted to print remaining characters of even or odd digit positions in the row of characters to be printed, the top surface of each of the first and second sets of type faces being retracted from the outer periphery of the printing drum, and each face being provided with a resilient member on at least a part of circumference thereof; a hammer unit positioned in the printing drum and provided with a plurality of hammers, the hammers being adapted to selectively thrust faces of the first and second sets through the outer periphery of the printing drum to bring the hammers in pressure contact with the recording m
