Abstract: A recording drum has a clamp groove extending in its circumferential direction formed on its outer peripheral surface. A plurality of front end clamps are attached to the outer peripheral surface of the recording drum. Rear end clamps are attached so as to be movable and so as to be fixable along the clamp groove on the outer peripheral surface of the recording drum. A recording head is disposed ahead of the recording drum, and a clamp driving device is disposed behind the recording drum. The clamp driving device comprises a first driving device for fixing the front end clamps and fixing and releasing the rear end clamps and a second driving device for releasing the front end clamps. The front end clamps and the rear end clamps reliably fix a front end and a rear end of a plate to the outer peripheral surface of the recording drum by a reaction force produced by a spring and a centrifugal force produced by the rotation of the recording drum.

Abstract: The present invention relates to a method and an arrangement for transferring a conductive picture (12) to an irregular surface of a mobile phone casing (4) for shielding the mobile phone casing from electromagnetic radiation. It also relates to the printing colour used for the conductive picture and tampon pads (5) used for the transferring of the conductive printing colour to the phone casing (4). Conductive partial pictures (7) are printed on the irregular surface of the casing (4) step by step by means of tampon pads until the complete conductive picture (12) is achieved. The tampon pad has a shape corresponding to the surface of the phone casing. The printing colour has a composition, which facilitates the adhering on the tampon pad. The invention also describes a method for printing an electrical circuit pattern on a phone casing (4) by using the above mentioned tampon pads and printing colour.

Abstract: An automatic paper sensing apparatus for an ink jet printer which can supply and print sheets of paper can automatically subsequently sense the existence of paper when a message indicating the absence of paper is generated. A first arm is fixed to the actuator feed in the direction of a separator, a second arm is mounted rotatably around a hinge axis at one side of the separator moved by an adjustable lever so as to interlock slidably with the first arm, the second arm being supported elastically by a tension coil spring fixed at one side thereof to the separator, one side of the actuator feed can be attached and detached to and from an optical sensor by means of the interlocking of the first and second arms. When the actuator feed and the separator are provided with an arm which is slidably interlocked with each other, the automatic sensing apparatus can automatically sense the subsequent existence of paper in order to facilitate convenient use of the printer.

Abstract: A keyboard device includes a plurality of keyswitches each having a keytop movable up and down, wherein the angle of the keytop varies depending on whether the keytop is in an initial position or in a pressed position. In this structure, the keytop moves in a direction corresponding to the motion of an operator's finger and thus smooth operations can be achieved, as opposed to a conventional keyboard device in which a keytop moves vertically while maintaining itself horizontal and thus the motion of the keytop occurs in a direction different from the motion of an operator's finger.

Abstract: A drying/curing apparatus for a rotary screen printing machine includes a carriage supporting a flash curing unit. The curing unit has a height or thickness that is less than the gap between the workpiece platen of the printing machine and the printing screen. The drying apparatus includes a structure attached to a print station of the printing machine that is configured to permit reciprocation of the curing unit across a substrate supported on the workpiece platen after an ink layer has been applied to the substrate and the platen has been retracted from the print screen. The curing unit includes a plurality of heat generating elements, such as high power quartz lamps, that are directed toward the ink layer on the substrate. The curing unit includes an insulator plate disposed between the curing lamps and the printing screen of the printing machine when the curing unit travels across the workpiece platen.

Abstract: A process of fabricating weather resistant signage by screen printing indicia on a UV-treated impregnated polyester protective film using a Cellosolve acetate-based ink. The resulting sign is extremely resistant to solar UV, thus preserving the indicia brightness and clarity for a very long period of time even under the most extreme conditions. The screen printing process of the preferred embodiment comprises the steps of first preparing a film image, then preparing a fabric mesh ranging from 125 to 230 mesh for black and white images and ranging from 355 to 425 mesh for halftone color images. The fabric mesh is attached to a stencil and the film image is attached to the stencil. The combination is placed into a vacuum frame for exposure to high intensity light, after which the stencil is washed with pressurized water, dried by fan, taped and touched up for pinholes or other blemishes.

Abstract: A re-useable stencil kit made of a semi-rigid panel material for the application of painted address characters and a decorative painted background on a street curb. A base decorative background stencil (10) having an elongated opening featuring a decorative shape (12, 28) at the right and left sides of the opening. Address characters formed in separate, character stencil cards (18) featuring one address character (20) each, are arranged within the cavity of the opening in the background stencil along with blank spacer cards (22, 24, 26) to form the desired address. The spacer cards fill in void space on either side of, and center the character stencil cards, simultaneously masking the painted background. The stencils and spacers fit closely together to prevent paint over spray and to provide accurate character alignment.

Abstract: A compact ribbon cassette for dispensing and storing a ribbon or tape. The supply and take-up rolls of ribbon or tape are disposed upon a common rotatable shaft mounted for rotation within the housing. A unique chevron disposed adjacent the take-up roll and on the post-printing portion of the cassette causes the dispensed ribbon to reverse direction and change level and to be presented for storage upon the take-up roll. The ribbon cassette also includes a partition disposed between the supply and take-up rolls for preventing ink particles in the take-up portion of the housing from migrating and thereby contaminating the printing ribbon.
