摘要： A printer is capable of preventing the formation of creases in a portion of an ink ribbon corresponding to a print head and of printing characters and images in good print quality without forming streaks attributable to creases in the ink ribbon. A main frame supports a feed spool and a takeup spool so that an ink ribbon extends between the feed spool and the takeup spool. A print head support frame supporting a print head and an ink ribbon guide is supported pivotally at one end thereof on the main frame. When the print head support frame is locked in place on the main frame, the ink ribbon guide depresses the ink ribbon so that the tension of a portion of the ink ribbon on one side of the main frame is higher than that of a portion of the same on the other side of the main frame while the printer is in an unoperational state and tension is distributed uniformly across a portion of the ink ribbon corresponding to the print head while the printer is in an operational state. Thus, creases are not formed in the ink ribbon while the printer is in the operational state.
摘要翻译：打印机能够防止在与打印头相对应的墨带的一部分中形成折痕，并且能够以良好的打印质量打印字符和图像，而不会形成可归因于墨带中的折痕的条纹。主框架支撑进给卷轴和卷取卷轴，使得墨带在进料卷轴和卷取卷轴之间延伸。支撑打印头和墨带引导件的打印头支撑框架在其一端枢转地支撑在主框架上。当打印头支撑框架被锁定在主框架上的适当位置时，墨带引导件压下墨带，使得主框架一侧的墨带部分的张力高于主框架的一部分当打印机处于操作状态时，打印机处于非操作状态，并且当打印机处于操作状态时，张力均匀地分布在与打印头对应的墨带的一部分上，在主框架的另一侧相同。因此，当打印机处于操作状态时，墨带中不会形成折痕。

摘要： A thermal transfer printing mechanism for use in a facsimile device includes a separating guide surface that is formed having a curve having a radius of curvature of not more than 1.2 mm. Consequently, the acceleration in a separating direction of an ink film separated from an image receiving sheet by the separating guide surface is increased, and the ink film is smoothly separated from the image receiving sheet. The separating guide surface may be formed as a bent thin plate, an embossed portion, a deformed edge of a supporting member, a plastic attachment, or a plastic tape. The separating guide surface is formed as a curve continuing from a feeding guide surface, and the feeding guide surface bends the sheet and the ink ribbon from a plane connecting a contact line of a thermal head and the ink ribbon and a contact line of the sheet and a sheet guide member provided downstream of the separating guide surface.

摘要： A liquid supply unit includes a main tank, a sub-tank, a pressure supply mechanism, an air communication hole, an air-permeable film and an excess pressure dispersion unit. The main tank stores liquid. The sub-tank is provided in a jet device, which ejects liquid droplets, and connected to the main tank. The pressure supply mechanism applies predetermined pressured to liquid in the main tank for supplying the liquid to the sub-tank. The air communication hole is provided on an upper surface of the sub-tank and communicates inside of the sub-tank with atmospheric air. The air-permeable film is provided for closing the air communication hole. The air-permeable film passes air, but not liquid. The excess pressure dispersion unit disperses excess pressure from the liquid supply unit when the liquid in the sub-tank becomes in contact with the air-permeable film and the pressure inside the sub-tank becomes higher than the predetermined pressure.

摘要： An air removal device for ink supply mechanism is provided which ensures separation of ink from an air permeable membrane after removal of air is completed. The air removal device includes an ink chamber, an air discharge passage, an air permeable membrane, a pump, and a movable member. The movable member is designed to be displaced between a first position and a second position. When the movable member is displaced to the second position to operate the pump, air collected in the ink chamber is discharged to the air discharge passage. When the pump is stopped and the movable member is displaced to the first position, one or both of air left in a portion of space in the ink chamber and air present downstream in an air discharge direction of the air permeable membrane flows in between the air permeable membrane and the ink inside the ink chamber.

摘要： At the lower end of a sheet-supporting surface, there is provided a fixed separation plate from and into the upper surface of which a separating device elongated in the sheet feed direction can protrude and retract. On either side thereof, there are provided first movable separation plates that can be inclined below the fixed separation plate. Stopper members are urged by an urging spring so as to pivot to a position below the supper surfaces of the first movable separation plates. When a pivoting operation lever is rotated, an operation arm is pressed by a cam mounted to an operation shaft through an operating portion, a second link, and a first link to upwardly rotate the stopper members, raising the lower edges of the stacked sheets above the upper surfaces of the separation plates to maintain the stacked set state.

摘要： In a sheet-supply device, a substantially T-shaped cutaway portion is provided in a projected portion, which is provided to an inclined wall and at a position corresponding to a sheet-supply roller near a lower end of the inclined wall that holds a stack of sheets loaded to a hopper portion. A first friction member is slidably supported in the cutaway portion so as to slide along the inclined wall from a downstream, normal position to an upstream position in a sheet feed direction. The first friction member includes a base portion and a pad portion, the pad portion is made of corkrubber and adhered to a surface of the base portion. A frictional coefficient μ of the pad portion is relatively high, i.e., frictional coefficient between adjacent sheets (approximately 0.6)≦μ≦1.0.

摘要： A sheet-supply device includes a pair of stopper members provided to a bottom plate of a hopper portion so as to move between a protruding position where upper surfaces of the stopper members protrude from a surface of the bottom plate and a retracted position where upper surfaces of the stopper members retract from the surface of the bottom plate, and a position change mechanism moving the stopper members between the protruding and retracted positions. By changing a timing of ascending the stopper members to the protruding position according to a type of the sheets to be fed, an appropriate resistance is applied to all of the sheets in the hopper portion except a topmost sheet during a sheet feed operation, thereby preventing a multi-feed problem. The stopper members moves up and down several times via the position change mechanism at a time between after the sheet feed operation is completed and before a next sheet feed operation starts, thereby positioning the sheets, which may cause the multi-feed problem, at a predetermined sheet holding position.
