摘要： A printer which is compact, can accurately supply paper and has reduced noise characteristics. Additionally, the printer enables easy correction of paper jams and can be selectively operated in various modes according to the user's preference. The printer includes a paper feed roller which is pivotable between a paper feed position and a non-feeding position, a drive force transmitting mechanism for transmitting a drive force to the paper feed roller, a carriage reciprocatively movable along the width of the paper fed by the paper feed roller, and an intermediate transmission mechanism attached to the side of the carriage. Only when the carriage is in a stand-by position, the intermediate transmission mechanism couples with the drive force transmitting mechanism to transmit to the paper feed roller a paper-feed directional rotating force so as to rotate the paper feed roller to the paper feed position. The intermediate transmission mechanism is preferably an idler rotatably mounted on the side of the carriage. The paper feed roller is preferably driven through a planetary gear mechanism including a sun gear provided on a drive shaft, a paper-feed roller holder rotatably mounted on the drive shaft, and a planetary gear coaxially provided with the paper feed roller supported with the paper-feed roller holder.

摘要： To avoid change in the property of an optical fiber, an optical fiber cord 100 has a structure fabricated by exposing a portion of the optical fiber 1 located at one end of an optical fiber core 15 which comprises a cushion layer 2 provided over the outer side of the optical fiber 1 and a cladding 3 provided over the outer side of the cushion layer 2; protecting one end of the exposed portion of the optical fiber 1 adjacent to the end of the cushion layer 3 with a roll of low hardness resin 4; and bonding the exposed portion of the optical fiber 1 to the capillary 32 of a ferrule 30 by an adhesive 20 so that the one end of the optical fiber core 15 is fixed integral with the ferrule 30. The stress of thermal shrinkage of the adhesive 20 is attenuated by the action of the low hardness resin 4 thus hardly acting on the optical fiber 1. Accordingly, a change in the property of the optical fiber 1 such as mode shift can be avoided.

摘要： One or more parts of an optical fiber is(are) exposed to a high temperature of gas flame for about 30 minutes so as to form one or more radially expanded core part(s) where a diameter of a core of the optical fiber is increased greater than its original size at a center and moderately decreased back to its original size as departing from the center. A part of the transmitting light leaks to the clad at the radially expanded core part. Leaked light hardly travels through the clad from the radially expanded core part to the output end of the optical fiber. This provides a function of an optical attenuator. Also, the attenuation is precisely adjusted to a desired level by controlling a size of the radially expanded core part. Furthermore, as an incident angle of the transmitting light from the core to the clad at the radially expanded core part becomes greater than conventional one, reflecting back the transmitting light to input side is prevented and the reflectance is minimized.
摘要翻译： 将光纤的一个或多个部分暴露于气体火焰的高温约30分钟，以便形成一个或多个径向扩大的芯部分，其中光纤的芯的直径增加 大于其中心的原始尺寸，并从中心偏离适度减小到原始尺寸。 透射光的一部分泄漏到径向膨胀的芯部的包层。 漏光几乎不会穿过包层从径向扩大的芯部到光纤的输出端。 这提供了光衰减器的功能。 此外，通过控制径向膨胀的芯部分的尺寸，将衰减精确地调节到期望的水平。 此外，由于从径向扩大的芯部的芯部到包层的透射光的入射角变得比常规透射光的入射角更大，所以防止透射光反射回输入侧，反射率最小化。
