  • Patent number: 5813774
    Abstract: A ticket-printing device has a ribbon sensor and a mode-switching circuit. The mode-switching circuit automatically selects different printing conditions depending on whether or not the ribbon sensor detects the presence of an ink ribbon. The ink ribbon is wound on a supply spool and take-up spool. When the ink ribbon is replaced, a ribbon fixture holds the supply spool and take-up spool in correct relative positions so that they can be easily slipped onto a supply spool shaft and take-up spool shaft in the ticket-printing device.

  • Patent number: 5813344
    Abstract: In a method and an apparatus for removing an image forming substance such as toner from an image holding member such as a sheet of transfer paper, a liquid providing unit is constructed by plural coating devices such as three coating devices each having a coating roller, a restricting roller and a liquid container for liquid storage. The coating devices are arranged along a conveying path of the transfer paper sheet. A liquid is provided to the transfer paper sheet from both face sides thereof by using a mist generator, etc. in the liquid providing unit. The coating and restricting rollers are arranged such that no coating and restricting rollers come in contact with the transfer paper sheet so as not to restrict the transfer paper sheet. A surface of each of the coating and restricting rollers is desirably constructed such that this surface is hydrophilic. Another toner removing apparatus is also shown. A drive roller device for supporting an offset belt for conveying the transfer paper sheet is also shown.

  • Patent number: 5813773
    Abstract: Two column-shaped ribs are disposed between a ribbon spool and an inner wall of a lower case in a cassette case. When a film tape is an ink-receiving type, which needs an ink ribbon, a pathway traveling to the outside of the ribs is selected so that the film tape traveling through the case can be reliably prevented from contacting the ink ribbon wound around the ribbon spool. On the contrary, when the film tape is a heat-sensitive type, wherein printing is performed by a thermal head directly heating the film tape, a pathway which travels between the ribs is selected so that the tape can be prevented from being drawn back when the tape is flexible like paper.

  • Patent number: 5813343
    Abstract: A printing media roll mounting mechanism including a frame defining a roll compartment for accommodating a printing media roll. First and second roll holders are mounted in the compartment in axial alignment substantially perpendicular to the web path for concurrent oppositely directed linear movement. The first and second roll holders are spring urged toward one another but can be moved apart to receive different width media rolls therebetween. When the first roll holder is moved outwardly, e.g., to the right, against the spring urging, the second roll holder will also move outwardly to the left. The two roll holders are spring urged toward each other to respectively engage opposite ends of a media roll core placed therebetween.

  • Patent number: 5813771
    Abstract: A method is described for calibrating a printer and/or a scanner so that information can be printed at a desired location with respect to a sheet, the method comprising: storing a first set of markings as a first image in digital form; printing, using a printer to be calibrated, the first image on a sheet to form a printed sheet; scanning the printed sheet to generate a second image stored in digital form; comparing the first image and the second image, or an image derived from the second image, to determine a first transformation which maps the first set of markings in the second image, or the image derived from the second image, onto the first set of markings on the first image; storing parameters of the first transformation for subsequent use by applying the first transformation to information to be printed at the desired location. Using this method the bias transformations associated with a printer and/or a scanner can be accurately measured and stored for future use in printing.

  • Patent number: 5809932
    Abstract: An apparatus for automatically milking animals comprising a milking machine provided with teat cups. Each teat cup has three lines connected thereto which include a line causing the teat cup to pulsate, a line for carrying milk from the teat cup, and an air suction line extending into an enlarged lower space above the connection of the milk line. In the air suction line, a sensor can be incorporated for the purpose of ascertaining the pressure in the space wherein the animal's teat is received. The three lines received by the teat cup may be defined by side-by-side passages through a common flexible integral line. The enlarged lower part which contains the space receiving the air suction line has a greater diameter than the upper part in which the teat of the animal is received, and the upper and lower parts are removably interconnected to each other.

  • Patent number: 5809876
    Abstract: An imprinting system having a print head with a plurality of type for transferring ink from an inked ribbon onto a substrate. A typeholder having an open ended cavity defined by side walls for retaining the plurality of type, wherein the typeholder is removably disposeable in a recess of the print head. At least one side wall portion of the cavity is removably coupleable to the typeholder for permitting insertion and removal of the plurality of type into and from the cavity. And a resilient member protrudes into the cavity from at least one of the side walls, wherein the resilient member biases the plurality of type toward one of other the side walls to prevent shifting of the type in the cavity. A resilient member urges a button protruding from an outer surface of the typeholder into contact with the recess of the print head, and a magnetized striker plate disposed on another outer surface of the typeholder cooperates to securely retain the typeholder in the recess of the print head.

  • Patent number: 5812156
    Abstract: A printing system includes a replaceable cartridge for housing a supply of consumable marking media. The cartridge includes a cartridge memory for recording printing system-related parameters, including marking media parameters. A replaceable printing device, such as an ink jet head, includes a printhead memory for recording printing device-related parameters. A processor is coupled to the cartridge memory, the printhead memory and is responsive to parameters read from both memories to derive printing system function control values that are dependent upon one or more marking media parameters from the cartridge memory and one or more parameters from the printhead memory. The processor is thus able (in the case of an ink jet printing system) to determine a current ink supply value from a cumulative usage value stored on the cartridge memory and a drop volume parameter stored on the printhead memory.
