Abstract:
An apparatus for processing used belts and bands of a machine for printing sheet elements comprises an accumulation bin having an upper portion for receiving the belts and bands from a supply arrangement and a lower portion provided with a grinder for grinding the belts and bands into small pieces. The grinder is automatically placed in operation intermittently under the control of a control arrangement, and the output of the grinder either discharges directly into a transport receptacle for the waste or into an evacuation pipe which conveys the waste to a transport receptacle at a remote location.
Abstract:
A thermal transfer type printing apparatus has a thermal head unit for selectively and thermally transferring an ink layer of an ink ribbon onto a paper sheet in response to printing information. The ink layer, in which blanks of ink corresponding to the printing information remain after printing, is heated and made molten by a heat roller, and the negative image formed by these ink blanks is thus rendered illegible.
Abstract:
A bursting apparatus is provided for separating and/or deleaving carbon paper from a multipart perforated continuous series of forms having carbon paper interleaved therein. The forms are fed to a bursting station which includes a clamp bar and a segmented bursting roller which is driven by a one-revolution clutch or the equivalent thereof. Each successive leading edge of the form actuates a stop-feed switch for automatically metering a single form length to the bursting station. The clutch is also actuated, thereby moving the clamp bar on the next succeeding form and the bursting roller revolves for one revolution to burst the leading form and deliver it to a deleaving station. The segmented burster roller has a slight helix on its engaging edge so that bursting tension will start at one edge and move progressively across the width of the form. The deleaving station has structure similar to that of the bursting station, but modified such that the clamping bar and bursting roller are positioned orthogonal to those in the bursting station and operate on the margin of the forms. When the leading edge of the form reaches stop fingers at the deleaving station, the clamp bar clamps one side margin of the form while the bursting roller revolves one revolution to separate the margin of the form to which the carbon paper is secured, thus deleaving the form. The bursting and deleaving operations are repetitive and continuous.
Abstract:
A printing device may include a medium conveying passage along which the printing medium is conveyed; a printing thermal head structured to heat an ink ribbon; a ribbon supplying part; a ribbon winding part; an erasing thermal head disposed between the printing thermal head and the ribbon winding part in a feed direction of the ink ribbon, the erasing thermal head heating the ink ribbon after ink is transferred by the printing thermal head; a transferred roller oppositely disposed to the erasing thermal head and is transferred with ink of the ink ribbon heated by the erasing thermal head; and a roller holding part which holds the transferred roller. The transferred roller may be capable of being attached to and detached from the roller holding part.
Abstract:
A printer with media supply spool adapted to sense type of media, and method of assembling same. A supply spool to be loaded into the printer is adapted to allow the printer to sense type of a media ribbon thereon. The supply spool comprises a shaft having a supply of media ribbon wound thereabout. A transceiver unit is disposed proximate the shaft. The transceiver is capable of transmitting a first electromagnetic field and sensing a second electromagnetic field. A transponder including a semi-conductor chip is integrally connected to the shaft and has encoded data previously stored therein indicative of the type of media ribbon. The chip is capable of receiving the first electromagnetic field to power the chip and then generating the second electromagnetic field as the chip is powered. The second electromagnetic field is characteristic of the data previously stored in the chip. The transceiver unit senses the second electromagnetic field, which second electromagnetic field has the data subsumed in the chip. The printer then operates in accordance with the data sensed by the transceiver to produce quality prints consistent with the type of donor being used.
Abstract:
The present invention discloses an image recording member in which a layer containing a setting type silicone resin having a Knoop hardness number of from 1 to 145 on the surface of a substrate made of paper, plastics or the like. Furthermore, this invention discloses a method for recycling an image recording member comprising the steps of contacting the image recording member with the outermost surface of an image releasing member, the outermost layer being formed from a pressure-sensitive adhesive or the like such as hot-melt silicone resin, heating these material and member to transfer a toner from the image recording member to the image releasing member, and separating the image recording member from the image releasing member. Thus, the invention can maintain good fixing of an image forming material with respect to the image recording member, while the image forming material can be removed from the image recording member without damaging the recording surface.
Abstract:
Apparatus for replenishing dye from a re-inkable belt after such apparatus has transferred dye to form an image in response to image signals on a moveable receiver includes a re-inkable belt moveable along an endless path and having a plurality of separated ink patches each one being adapted to receive and transfer a different colorant and a re-inking turret having a plurality of rollers each one of has different transferable colorant and corresponds to a particular ink patch. The receiver is moved into proximate contact with the ink patches at a nip position. The apparatus responds to the image signals for applying energy to the re-inkable belt at the nip position to imagewise transfer colorant from the re-inkable belt to the receiver depleting colorant in an imagewise pattern and imagewise replenishment of depleted colorant on the ink patches of the ink belt to transfer colorant into the ink transfer surface includes a structure responsive to the image signals and the position of the re-inkable belt to cause particular rollers to engage corresponding moving ink patches at an ink transfer position for transferring ink to such patches such that the transfer of colorant from each roller to the corresponding patches is in synchronization with the movement of the re-inkable belt.
Abstract:
A heat transfer recording apparatus for recording an image on a recording medium by transferring an ink possessed by an ink sheet to the transfer medium comprises conveying means for conveying the ink sheet and the recording medium, recording means for recording an image on the recording medium, and control means for controlling the recording means after an image has been recorded by the recording means so as to record the image over again by using the same data after the ink sheet has been conveyed while the recording medium being stopped.
Abstract:
A thermal transfer printing apparatus that comprises a thermal head, an ink transfer medium having an ink layer, a printing medium to which the ink is to be transferred, a platen for pressing the ink transfer medium together with the printing medium against the thermal head. The thermal head comprises a substrate, a plurality of heating elements disposed on a surface of the substrate close to an end of the substrate and two electrode lines connected to each of the plurality of heating elements and formed on the substrate. Each line extends from each heating element toward a direction opposite to the substrate end with respect to the heating elements. The apparatus further comprises a pulling out unit for separating and pulling out the ink transer medium from the printing medium after passing over a position of the heating elements and a direction change mechanism for changing direction of the ink transfer medium pulled out by the pulling out unit with respect to the surface of the substrate.
