    摘要： A cutting mechanism for a printing apparatus is described. The cutting mechanism is particularly suitable for tape printers. In the cutting mechanism, one of a cutting blade and an anvil is mounted for rolling motion with respect to the other so that as the rolling motion occurs a cut is made through the tape. Moreover, the cutting mechanism can be actuated by a handle which lies flush with the printer casing and which can be actuated externally of the casing.

    摘要： When selected documents traveling along a first feed path (46) are to be fed to a second feed path (48), a solenoid is energized causing pivotal movement of a pair of flipper arms (56a, 56b) so as to direct the documents onto the second feed path (48). When the solenoid is de-energized, documents on the first feed path (46) may proceed to the continuation portion thereof i.e., path (46a), or documents from the second feed path (48) may be fed to the continuation portion (46a) of the first feed path (46). The flipper arms (56a, 56b) are coupled by gearing mechanisms so that they are moveable relative to each other, pivotal movement of one flipper arm (56a, 56b) causing pivotal movement of the other arm (56a, 56b). Such relative movement between the flipper arms (56a, 56b) allows for a compact and reliable structure and activation of the mechanism is required only when documents are to be fed from the first feed path (46) to the second feed path (48).

    摘要翻译： 当沿着第一馈送路径（46）行进的选定文件被馈送到第二馈送路径（48）时，螺线管被激励，从而引起一对翻转臂（56a，56b）的枢转运动，以便将文档引导到 第二进给路径（48）。 当螺线管断电时，第一馈送路径（46）上的文件可以进行到其继续部分，即路径（46a），或者来自第二馈送路径（48）的文档可以被馈送到连续部分（46a） ）的第一馈送路径（46）。 引导臂（56a，56b）通过传动机构联接，使得它们相对于彼此可移动，一个引导臂（56a，56b）的枢转运动引起另一个臂（56a，56b）的枢转运动。 引导臂（56a，56b）之间的这种相对运动允许紧凑且可靠的结构，并且只有当文件从第一进给路径（46）进给到第二进给路径（48）时才需要启动机构。

    摘要： An automatic tape detecting and tape width identifying printing apparatus or tape holder wherein the printing apparatus and tape holder include an optical sensing arrangement having at least first and second optical sensing assemblies. The first and second optical sensing assemblies each, preferably, include a photo transistor and a light emitting diode. The photo transistor is located to receive and detect light from the light emitting diode. The first and second optical sensing assemblies are located to automatically detect the presence or absence of tape within the tape holder. In a preferred embodiment, the first optical sensing assembly is located to automatically discriminate the presence of a particular width, w2, of tape within the tape holder. In addition, the second optical sensing assembly is located to automatically discriminate the presence of a different width, w1, of tape within the tape holder. The presence or absence of tape, and, if present, the width of the tape are automatically detected and a signal indicating such is transmitted from the first and/or second optical sensing assemblies to a controller. The controller prevents operation of the print head in the absence of tape and, when present, controls the print head to print within the width of tape detected. Thus, the present invention automatically prevents damage to the print head or platen of the printing apparatus.
