  • Patent number: 10518537
    Abstract: An inkjet printer is configured with capping stations for storing printheads in the printer during periods of printer inactivity so the viscosity of the ink in the nozzles of the inkjets of the printheads does not increase significantly. Each capping station has a printhead receptacle with an opening corresponding to a perimeter of a printhead, a pair of members pivotably mounted to the printhead receptacle so the members can move between a first position where the members expose the opening of the printhead receptacle and a second position where the members cover the opening of the printhead receptacle, and an actuator operatively connected to the pair of members to move the members between the first position and the second position. A controller is operatively connected to the actuator to operate the first actuator to move the members between the first position and the second position.

  • Patent number: 7096785
    Abstract: A stamp pad holder for use in a self-inking hand stamp. The stamp pad holder has a stamp die box that holds a stamp forming material, ink cartridge and plastic within the die box. The stamp forming material is placed at the bottom of the die box. An ink cartridge having a layer of soft, compressible, ink permeable material applied to its bottom surface is placed above the stamp forming material but separated by an impermeable film. The film prohibits ink from flowing from the ink cartridge to the stamp forming material until the film is pulled from the die box prior to use. This permits the ink from the ink cartridge to impregnate the stamp forming material. The soft, compressible, ink permeable material increases the rate of ink flow from the ink cartridge to the stamp forming material.

    Abstract: An integrated circuit screen printing nozzle that has a nozzle body, a first inner layer on the nozzle body, a second outer layer on the first layer, and an opening through the nozzle body, the first layer, and the second layer. The first and second layers can be an insert held within the body. The opening allows paste material to flow through the screen printing nozzle to the stencil mask. Also, the second outer layer includes a contact surface adapted to contact the stencil mask. One feature of the invention is that the first layer is softer (has a lower durometer) than the second layer. This allows the second layer to be more durable than the first layer and for the first layer to provide additional flexibility to the second layer. Therefore, the invention provides a nozzle that has the high durability characteristics of a hard outer surface with the compliance of a soft nozzle.

The stencil stamp includes a handgrip and a stencil stamp assembly. The stencil stamp assembly includes an ink bearing member covered with a thermal stencil sheet. The thermal stencil sheet has a plurality of pores on holes arranged in a pattern. During a stamping action, ink from the ink bearing member is forced through the pores in the stencil sheet and onto a recording sheet to form a stamped image on the recording sheet. The ink bearing member has at least two layers having different densities. The less dense layer is in contact with the thermal stencil sheet. The least dense layer provides a large ink storage capacity. The more dense layer has a higher ink holding capacity, which reduces the potential for ink leakage.

  • Patent number: 5595112
    Abstract: A guide hole 18 is formed in a left side wall 17 of a grip 2 provided to a stamp assembly 1. When the stamp assembly 1 is mounted to a thermal perforation unit 50, a guide bar 38 provided to the thermal perforation unit 50 is inserted into the guide hole 18. A protector clasp 18a for opening and closing the guide hole 18 is provided to the left side wall 17. The protector clasp 18a can be manually slid up and down in a protector clasp groove 17a. When the protector clasp 18a is in a lower position shown in FIG. 1 (a), the guide hole 18 is closed so that the stamp assembly 1 can not be mounted to the thermal perforation unit 50. When the protector clasp 18a is in an upper position shown in FIG. 1 (b), the guide hole 18 is closed so that the stamp assembly 1 can be mounted to the-thermal perforation unit 50.

  • Patent number: 5551337
    Abstract: A plate making device and method, wherein when a light sensor detects that the stencil plate inserted into the plate making device is provided with the through hole, the controller supplies a current to the thermal head for T1 seconds to control the heat time to be short, so that the perforation energy of the thermal head is reduced. On the other hand, when the light sensor detects that the stencil plate has no through hole, the controller supplies a current to the thermal head for T2 seconds longer than T1 seconds to control the heat time to be long, so that the perforation energy of the thermal head is increased. In this device, even when any type of stencil plate is used, the plate making process providing the best print quality for each stencil plate can be performed.

  • Patent number: 5483880
    Abstract: A stamp unit includes a grip portion to be grasped by a hand, a stamp portion that is fixedly linked to the grip portion, a skirt member covering the outer peripheral side of the stamp side, and a protection cap that is freely detachably mounted on the stamp portion. The skirt member is upwardly and downwardly slidably supported. At its nonuse time, the lower end of the skirt member projects to a position lower than a print face portion of the stamp portion. However, by locating the stamp unit at a print position and pressing the grip portion, the skirt member is moved upwardly, and the print face portion of the stamp member is pressed against a print surface, whereby ink oozes out from the print face portion to perform the print operation. The stamp unit is further provided with plural engaging holes formed at the lower portion of the grip member and plural engaging pawls that are provided at the upper portion of the stamp member and elastically engaged with the respective engaging holes.

  • Patent number: 5329848
    Abstract: To eliminate wasteful use of thermal stencil paper and thereby provide an inexpensive stamp device, a single thermal head is employed for both the thermal recording on a reversible thermal recording sheet for confirmation of a stamp image and the thermal perforation through the thermal stencil paper for creation of a stamp original. The stamp image is first thermally recorded on the reversible thermal recording sheet; the stamp image thus recorded is then confirmed; and the thermal stencil paper is thermally perforated in accordance with the stamp image to create the stamp original.
