  • Patent number: 8147155
    Abstract: A roll paper printer having a roll paper compartment in which roll paper is mounted so that it is freely rotatable inside the roll paper compartment with the compartment designed to prevent the roll paper from meandering from a given path of travel along which the paper roll is unwound. The design of the compartment prevents the edges of the paper from catching on steps between pairs of roll paper guides connected to or forming the sides of the roll paper compartment. Movable roll paper positioning plates 31 and 32 are urged toward each other by a tension spring 37 in the roll paper compartment 9 of the printer 1 located near the top of one pair of roll paper guides 28 and 29. The movable roll paper positioning plates 31 and 32 have roll paper positioning surfaces 31a and 32a which can contact the outside circumference part of the ends 10b and 10c of the roll paper 10.

  • Patent number: 8149850
    Abstract: A system and method for mediating the routing of asynchronous messages includes routing the asynchronous message to a first recipient, determining whether the first recipient opened the asynchronous message, and re-routing the asynchronous message to a second recipient who is qualified to receive and respond to the message if the first recipient fails to open the message. In an aspect, the second recipient is selected based upon the role that the second recipient performs within the system. In another aspect, the message is re-routed to the second recipient if the first recipient fails to open the message within a deadline imposed by the message sender. In another aspect, the message is re-routed to the second recipient if the first recipient fails to open the message within a deadline automatically imposed by the system when the message is of a certain type.
