  • Publication number: 20210212265
    Abstract: A modular flower panel adapter system is implemented in which individual flower panels are collectively utilized to hold and feature an arrangement of flowers. The flower panels, which are already holding an arrangement of flowers, are transportable using an adapter panel and a delivery cage. The adapter provides greater surface area for transportation and handling of the flower panel. A rack system and delivery cage are implemented to transport the combined unit of the flower panel and the adapter panel to an event. At the event, the adapter panel is disconnected and the flower panel is connected to a structural panel and support panel for assembly. Multiple structural panels are connected together using connectors, and each structural panel is attached to an individual flower panel for exhibition. A collection of flower panels laterally and adjacently positioned create a robust and customizable flower wall arrangement that is easily transportable and assembled.

  • Patent number: 6031599
    Abstract: The present invention provides a photo printer with an adjustable thermal print head. The printer includes a cantilever mechanism that raises or lowers a thermal print head for either removing a photo or printing the photo. The force exerted on the thermal print head is adjusted by an adjusting mechanism which uses an elastic mechanism with an adjusting screw and a spring. A platen roller feeds the photo through the device. The contacting stress between the thermal print heads and the platen roller is individually adjusted so that pressure can be maintained evenly at all times.

  • Patent number: 5997199
    Abstract: The present invention relates to a paper feeding module of a color picture printer for driving a picture back and forth through a printing module of the printer for printing. The printer comprises a housing. The printing module is installed inside the housing for printing the paper. The paper feeding module comprises a first roller, a second roller and an elastic device. The first roller is horizontally installed inside the housing and is rotatable. The second roller comprises at least two cylindrical sleeves mounted onto a revolving axle for clamping the paper with the first roller. The second roller is installed in parallel with, in contact with and above the first roller inside the housing, is moveable in a vertical direction, and is rotatable. When the first and second rollers are rotated in opposite directions, the paper is clamped and driven between the first roller and the sleeves of the second roller.
