    摘要： A printer for use with an ink ribbon having at least two printing tracks is provided with a print head that moves along a predetermined path adjacent to a recording medium. A line driver reciprocates the print head along the path in first and second directions. A multi-track ribbon comprises a plurality of printing tracks having portions thereof disposed between the print heads and a recording medium. A ribbon shift mechanism positions a preselected one of the tracks on the ink ribbon adjacent the print head for use in printing a response to movement of the print head. The ribbon shift mechanism comprises a printing track setting mechanism for moving the ribbon in one direction to set at one desired track height from among several preselected track heights corresponding to a selected one of predetermined amounts of movement of the print head in the first direction to a first end portion of the path. The ribbon shift mechanism also comprises a printing track releasing mechanism for moving the ribbon in an opposite direction to release from the set track height in response to movement of the print head in the second direction to a second end portion of the path.

    摘要： A compact, lightweight printer capable of using multi-track ink ribbons that facilitates multicolor printing, without having a dedicated track switching drive system. The printer employs a printing track setting member that is activated by contact pressure from a print head carriage when it moves in one direction and vertically displaces a ribbon frame supporting the ribbon to one of several preselected heights with respect to the print head. The setting member is preferably made in the form of a setting lever with a drive end for interacting with the print head carriage and a setting end with a series of setting height stops that interact with the ribbon frame. Rotation of the setting lever places different setting level stops under the frame which varies its height accordingly. A printing track release member is also provided which is activated by contact pressure from the print head carriage when it moves in an opposite direction and raises the ribbon frame to disengage the track setting member and move the ribbon support frame to a new height. The track release member is preferably formed as a rotatable release shaft with drive end for interacting with the print head carriage and a release end with a lever extending under and toward the ribbon cassette. Rotation of the track release member shaft causes the lever to raise the ribbon frame accordingly.

    摘要： A winding shaft, for use in a printer allows a wound recording paper to be easily removed therefrom. The winding shaft includes a shaft main body, a winding portion and a support-removing member. The winding portion, which sandwiches the shaft main body, winds the recording paper therearound. The shaft main body includes a pair of support-removing members, which respectively project from the shaft main body. The two support-removing members are respectively supported on the two side portions of the shaft main body in such a manner that they can be freely rotated about their respective support shafts. A tension-coiled spring is bridgingly disposed between the two support-removing members, so that the two support-removing members remain in standing positions when no external force is applied to them. If the recording paper is lightly rotated in a direction opposite to the winding direction of the recording paper, then the two support-removing members are brought down in the same direction due to an external force applied thereto from the innermost peripheral recording paper. As a result, the innermost peripheral recording paper is loosened, that is, is caused to float loosely from the outer peripheral surface of the shaft main body, thereby enabling the removal of the recording paper from the winding shaft.

    摘要翻译： 用于打印机中的卷绕轴允许容易地从其上移除卷绕的记录纸。 卷绕轴包括轴主体，卷绕部分和支撑件移除部件。 卷绕轴主体的卷绕部分绕着记录纸卷绕。 轴主体包括分别从轴主体突出的一对支撑移除构件。 两个支撑移除部件分别支撑在轴主体的两个侧部上，使得它们能够绕其各自的支撑轴自由旋转。 张紧螺旋弹簧桥接地布置在两个支撑移除构件之间，使得当没有施加外力时，两个支撑件移除构件保持在竖立位置。 如果记录纸在与记录纸的卷绕方向相反的方向上轻微旋转，则两个支撑件移除部件由于从最内侧的周边记录纸施加到其上的外力而沿同一方向下降。 结果，最内侧的周边记录纸被松动，从而从轴主体的外周表面松动地浮动，从而能够从卷轴移除记录纸。

    摘要： A print head 6 is disposed next to a transportation path for transporting a cut-sheet form V. A guide frame 17 with a guide member 17a projecting into the transportation path away from the print head 6 is disposed on the cut-sheet form V insertion opening side of the print head 6. A platen unit 16 with a platen 33 is mounted to rotate freely, and a frame member 30 is disposed on the platen unit 16. When the platen unit 16 is closed, the guide member 17a of the guide frame 17 and the guide member 30b of the frame member 30 touch, thus forming an ejection path guiding the roll paper S away from the junction with the cut-sheet form V transportation path. When the platen unit 16 is opened, the guide member 17a of guide frame 17 and the guide member 30b of frame member 30 separate, thereby enabling cut-sheet form V insertion.

    摘要： A printing apparatus comprises a platen, a dot impact print head (23) opposite to the platen, a mask plate (40) between the platen and the print head with a paper passage between the platen and the mask plate (40), and an ink ribbon (31) between the print head and the mask plate. Transport mechanisms are provided to move the mask plate (40) in a direction substantially perpendicular to said paper passage between a first position on the print head side and a second position on the platen side, the transport mechanisms being responsive to the position of the print head along the platen. In the first position of the mask plate a relatively wide gap between the platen and the mask plate enables easy paper insertion, while in the second position a relatively wide gap between the mask plate and the print head facilitates replacement of the ink ribbon without problems.
