Abstract: An image forming apparatus includes an upper body, an image reading device that is mounted in the upper body, a lower body that is placed under the upper body, an image forming device that is mounted in the lower body, a hinge member that connects the upper body and the lower body, at least one groove that is formed on the lower body, at least one link member that is connected to the upper body at one end and connected to the groove at the other end, and at least one elastic member that is connected to the lower body at one end and the link member at the other end. The groove has a first range where a moment to pivot the upper body to the close position is generated.

Abstract: An ink ribbon is formed from a belt shaped sheet body, and is wound around a pair of tubes. Spools are detachably mounted at each end of the tube bodies. An ink ribbon cartridge includes side plates formed with supporting openings for supporting corresponding spools. When the ink ribbon cartridge is mounted in a printing device, the spools are freely rotatable within the supporting openings. A protrusion is formed in an upper surface of the takeup-side of the cartridge. The protrusion provides a handle and an opening is formed in the takeup-side upper surface beneath the protrusion.

Abstract: An ink ribbon cartridge includes a frame having a first side, a second side, a third side, and fourth side. The first side and the second side extend in a widthwise direction and have supporting portions. The third side and the fourth side extend between the first side and the second side in a lengthwise direction perpendicular to the widthwise direction. The third side is formed with a protrusion protruding upward from an upper surface of the third side. A pair of tubes extend in the lengthwise direction and are supported by the supporting portions. An ink ribbon is wound around the pair of tubes.

Abstract: An upper case 5 is pivotable with respect to a case 2 by attachment with two frames 37. A sheet-supply tray 6 is pivotably mounted on the upper case 5. The sheet-supply tray 6 has a pair of left and right guides 35, 35 at a position near a sheet-supply port 13. The guides 35, 35 have a pair of separation ribs 42, 42 that define therebelow a sheet-supply pathway and thereabove a sheet discharge pathway. A synthetic resin hollow frame 40 with an integral slide rib 41 is fixed to the case 2. The slide rib 41 is formed with an outwardly curving surface 41a that is eccentric with an imaginary circle around a pivot shaft 38 of the upper case 5, wherein the free end of the slide rib 41 is farther from the shaft 38 than the fixed end. A horizontally protruding pin is fixed on one of the frames 37, and so pivots following the imaginary circle around the shaft 38.

Abstract: An ink ribbon is formed form a belt shaped sheet body, and is wound around a pair of tubes. Spools are detachably mounted at each end of the tube bodies. An ink ribbon cartridge includes side plates formed with supporting openings for supporting corresponding spools. Each supporting opening is formed with a cutout portion defined by edges. When the ink ribbon cartridge is mounted in a facsimile machine, the spools are freely rotatable within the supporting openings. On the other hand, when the ink ribbon cartridge is dismounted from the facsimile machine, engagement protrusions formed to the spools catch on the edges defining the cutout portions, thereby preventing the spools form rotating. As a result, the ink ribbon will not unintentionally greatly loosen.

Abstract: The invention provides an ink ribbon cartridge which ensures proper, reliable mounting of an ink ribbon. The ink ribbon cartridge of the invention includes a pair of spools, an ink ribbon including a band-like sheet wound around the pair of spools and provided with a layer of ink formed on one surface thereof, four spindles which have disk-shaped sections at one end and can be placed, for a specific length in both ends of the pair of spools, and a cover covering the pair of spools around which the sheet is wound and having four round holes in which the disk-shaped sections of each of the spindles are loosely fitted. In one of the four ends of the pair of spools, only the other end of a specific one of the four spindles can be inserted for a specific length, and one of the four round holes formed in the cover is formed such that only the disk-shaped section on one side of the specific spindle can be loosely fitted.

Abstract: A ribbon cassette is easily loaded without allowing a torsion force to be acted when the cassette is loaded into a printing apparatus and/or a facsimile apparatus each using the ribbon cassette. A ribbon cassette has a ribbon supplying part for supplying an ink ribbon, a ribbon take-up part for taking up the ink ribbon which is led from the ribbon supplying part and passed between a print head and a platen roller, and connecting parts for connecting the supplying and take-up parts. The connecting parts are provided with projecting holding parts for attachment or detachment, and the holding parts are positioned near the ribbon take-up part positioning on the side remote from a hinge member.
