Abstract:
A printer includes printing unit provided on a conveying path of a recording sheet and sheet feed unit provided on the downstream and upstream sides of the printing unit in a conveying direction of a recording sheet. The printer includes a platen roller, a first sheet feed roller, a second sheet feed roller, a first branch transmission gear group, a second branch transmission gear group, and thrust amount adjusting unit. A tooth trace of one of the gears of each of the first and second branch transmission gear groups has an inclination angle with respect to an axial direction, and the first and second branch transmission gear groups are formed of first and second idler gears including inclined gear portions of which inclined directions of tooth traces are the same as each other.

Abstract:
The present invention is directed to providing a paper carrying mechanism for a printing device, in which the number of parts and assembly processes can be reduced, and which the carrying deviation does not occur even if a recording medium is reciprocally carried. The paper carrying mechanism for a printer comprises a rotatable carrying roller 2, and a rotatable pressing roller 3 arranged above the carrying roller 2. The pressing roller 3 is arranged to have a gap G of ½ of the thickness of a recording medium 5, between the pressing roller 3 and the carrying roller 2. When the recording medium 5 is carried to the gap G, the pressing roller 3 is pushed up so that the carrying roller 2 is pressed against the recording medium 5 due to the weight of the pressing roller 3.

Abstract:
A ribbon cassette structure integrated with a paper feed tray includes a ribbon cassette that includes a pair of bobbin receiving units and is integrated with a paper feed tray. One of the pair of bobbin receiving units that are connected to each other, and the paper feed tray are pivotally connected to each other so as to be opened or closed between an open state where the one of the pair of bobbin receiving units and the paper feed tray are mostly separated from each other, and a closed state where the one of the pair of bobbin receiving units and the paper feed tray come in contact with each other.
Abstract:
In a printer having a printing means for printing a desired image on a recording paper, a switching means for switching a print condition of the printing means corresponding to the type of the recording paper is arranged. In a vicinity of a storage unit of the paper tray, a switching knob for switching printing in a full-page layout on the entire surface of the recording paper or in a divided layout on the recording paper divided into a predetermined number of pieces is arranged. By mounting the paper tray in a tray mounting portion of the printer, the print condition is switched corresponding to the type of the recording paper used, and by operating the switching means with the switching knob, the switching is performed to print in the divided layout or in the full-page layout.
Abstract:
A ribbon cassette contains an ink ribbon, a supply core and winding core around which ends of the ink ribbon are wound, a cassette case for rotatably supporting the supply rewinding cores, and a ribbon guide part guiding the path of the ink ribbon. The ink ribbon guide part is a meandering preventing portion constructed such that a portion of the ink ribbon guide part to be brought into slidable contact with a widthwise middle portion of the ink ribbon is wider than portions to be brought into slidable contact with widthwise ends of the ink ribbon. Further, by fitting both ends of a guide shaft for guiding the ink ribbon into first and second holes formed in first and second wall portions formed on the cassette case, the guide shaft 8 is rotatably supported in the first and second holes.
Abstract:
A computer including a body case housing a display, an outer member formed of an impact-resistant material integrally formed on the outside surface of the body case, and an outwardly-projecting cushioning portion formed at each corner of the outside member. Each of the cushioning portions has a first protective portion extending outwardly from the body case, and a second protective portion projecting curvilinearly with respect to the first protective portion and extending onto a surface or a back side of the body case. The cushioning portions are formed of an elastic material. Further, vent holes are formed in the body case which are sealed with a porous film which is permeable to gas but not permeable to water. The vent holes provide an escape path for gas produced by a battery, such as a nickel-hydrogen battery, in the event that the battery explodes within the body case.
