  • Publication number: 20170021571
    Abstract: The manufacturing apparatus (1) for three-dimensional moldings is provided with a molding block (20), a tag-supplying block (30) and a control unit (12). The molding block (20) is a molding device for molding a three-dimensional object by successively layering molding material layer by layer. The tag-supplying block (30) is a tag-supplying device for supplying a wireless communication tag to a specified position. The control unit (12) causes the tag-supplying block (30) to supply the wireless communication tag to the specified position of the molding material during layering of the molding material by the molding block (20) so that the wireless communication tag is embedded inside the three-dimensional molding that is obtained by layering the molding material.

  • Patent number: 9041973
    Abstract: Having specified written information on a first card newly placed at a base A which is a first workspace and the position where the first card is placed, a PC (100A) which is a control device at base A stores, in a memory, the written information and the position where the first card is placed as card information. A PC (100B) connected to this PC instructs a printing device (200B) to print a second card based on the specified written information. The PC (100B) presents the position where the second card is to be placed at a base B which is a second workspace based on the specified position where the first card is placed.

  • Patent number: 8891994
    Abstract: An image forming apparatus includes a secondary transfer belt that rotates, an imaging unit for forming a patch image of toner on the secondary transfer belt, and an upstream brush and a downstream brush coming into contact with the secondary transfer belt in a rotating state to remove the patch image from on the secondary transfer belt. A length p of the patch image formed by the imaging unit along a rotational direction of the secondary transfer belt, a distance b1 over which the secondary transfer belt rotates while the upstream brush makes one turn, and a distance b2 over which the secondary transfer belt rotates while the downstream brush makes one turn satisfy an expression: p?|b1?b2|.

  • Patent number: 8200125
    Abstract: A developing device using a liquid developer removes developer using the contact-rotation between rollers such as a developing roller and thin layer forming roller when an image is not formed, and includes a contact pressure modification section that modifies the contact pressure in the contact region between rollers rotating in contact with one another. When operation is performed to remove the developer using the contact-rotation between rollers with the supply of liquid developer being suspended, modifications are made to ensure that the contact pressure in the contact region is smaller than that during image formation.
