摘要： A sheet detection apparatus is provided which determines the presence or absence of a sheet on a sheet feed path as well as the type of sheet. The apparatus utilizes a light source to direct a predetermined amount of light to a sensor by reflecting off a sheet on the feed path or a reflector in the absence of any such sheet on the path. The presence or absence of the sheet is determined by comparing the output value of the sensor with predetermined reference values.

摘要： Ribbon lifting apparatus for a printing device having a print wheel and a ribbon cartridge. The lifting apparatus includes a pair of ribbon guides for supporting an exposed portion of a ribbon extending from an outlet opening of the ribbon cartridge to an inlet opening thereof. The pair of ribbon guides are supported by respective pairs of supporting levers which are swung in a plane parallel to the face plane of the print wheel. The pair of ribbon guides are lifted so that the lifting movement of the guides causes variation of a distance therebetween for keeping the path of the exposed length of ribbon substantially constant.

摘要： The carriage mounting the print head, for a printer, is supported at an upper guide bar with an upper bearing and at a lower guide bar with a lower-right bearing and a lower-left bearing. The printing device prints characters while driving the print head in reciprocal movement along the guide bars. The lower-left bearing has an eccentric center relative to the axis of the lower-guide bar. A lever fitted on the lower-left bearing allows the operator to rotate the lower-left bearing relative to the axis of the lower guide bar to adjust the height of print.

摘要： A sheet feed device for feeding sheets from a stack to a machine, such as a copier, is provided with rollers for feeding the top sheet of the stack to the entrance of the machine. When a sheet is being fed through the machine, the presence of the sheet is sensed and used to generate a signal to disengage the rollers from the stack to thereby ensure precise feeding of the sheets.

摘要： A sheet feed mechanism has an array of suction cups into and out of contact with an uppermost one of stacked sheets in a sheet cassette. After the suction cups are held against the uppermost sheet, a vacuum is developed in the suction cups to enable the suction cups to attract the uppermost sheet. Then, the suction cups are lifted with the uppermost sheet attracted thereto, and a leading end of the attracted and lifted uppermost sheet is nipped, and the sheet is delivered into a sheet feed path. When the suction cups are lifted, they are angularly moved about an axis to cause the leading end of the attracted uppermost sheet to be obliquely separated from other stacked sheets.

摘要： A feeding device for a printer having a combination of at least one feeding roller with an opposing pinch roller both upstream and downstream, in the feed direction, of a print position. The upstream and downstream side paper feeding rollers are made from metal and the upstream and downstream pinch rollers are made of a elastic material. The upstream and downstream side paper feeding rollers feed a paper sandwiched between the feeding rollers and opposing pinch rollers. The nip pressure on the downstream side is slightly stronger than the nip pressure on the upstream side so that the feed rate is slightly higher at the downstream side than at the upstream side. As a result, the paper is tant as it moves past the print position. Further, the paper is accurately positioned for each line, even after the paper has cleared than nip of the upstream side paper feeding and pinch rollers.
摘要翻译：一种用于打印机的进给装置，其具有在打印位置的进给方向上的上游和下游的至少一个进给辊和相对的夹送辊的组合。上游侧和下游侧进纸辊由金属制成，上游和下游夹送辊由弹性材料制成。上游侧和下游侧进纸辊供给夹在进料辊和相对夹送辊之间的纸。下游侧的辊隙压力比上游侧的辊隙压力略强，使得进料速率在下游侧比在上游侧略高。因此，纸张移动印刷位置是重要的。此外，即使在纸张已经比上游侧进纸和夹送辊的辊隙更清洁之后，纸张也被精确地定位。

摘要： A sheet feed arrangement having an upstream first and downstream second rollers for defining a part of a sheet feed path therebetween. A first sheet detector is disposed upstream of the first roller and a second sheet detector is disposed downstream of the second roller. These detectors transmit sheet detection signals when the sheet passes therealong. The detection signals are transmittable to a control unit. The control unit is connected to a first roller drive motor and stops rotation thereof if the sheet detection by the first detector is finished whereas a leading end of the sheet has not yet been detected by the second detector. If desired, the first roller is reversely rotated to discharge the sheet toward the upstream or sheet inlet side.
