摘要： A printer paper feed apparatus having a single-form feed function and a continuous-form feed function, in which a pin tractor mechanism (4) for feeding the continuous forms is situated upstream of the platen (11) and including a guide plate (3) for the single forms, pivotally supported (at 50) in the vicinity of a single-form insertion inlet (17a) for selectively assuming a horizontally accomodated position and a single-form insertion guide inclined position, a clutch (27) providing in a transmission system between a drive shaft (32) of the pin tractor mechanism (4) and the paper feed motor (12), and a mechanism for controlling engagement and disengagement of the clutch in dependence upon whether the guide plate (3) in the accomodated position or the inclined position. In the latter case, the clutch (27) is disengaged by the projection (54) of the guide plate (3) thereby terminating drive of the pin tractor mechanism (4).

摘要： A lens shutter comprises a shutter blades opening and closing lever (4) and an electrostrictive strain element (5) driving the lever (4). The arrangement being such that inertia forces acting on said lever (4) through engagement with said element (5) and vice versa are counterbalanced by each other, in order to eliminate variations of exposure caused by various positions of a camera. The basic portion of the electrostrictive strain element (5) is secured to a retaining member (6) supported rotatably on a shutter base plate (1) and the retaining member (6) may well be biased by a spring (8) to increase the inertia force of the electrostrictive strain element (5). Thereby, even if a shock is applied to the shutter from the outside, the shutter blades (2, 2ʹ) are not inadvertently opened and closed. The rotation of the retaining member (6) to rotate the opening and closing lever (4) in a wrong direction is prevented by an eccentric pin (9).
摘要翻译：透镜挡板包括快门叶片打开和关闭杆（4）和驱动杆（4）的电致伸缩应变元件（5）。该布置使得通过与所述元件（5）接合而作用在所述杆（4）上的惯性力彼此抵消，以便消除由相机的各种位置引起的曝光的变化。电致伸缩应变元件（5）的基本部分被固定到可旋转地支撑在闸板基板（1）上的保持构件（6）上，并且保持构件（6）可以很好地被弹簧（8）偏置，以增加电致伸缩应变元件（5）的惯性力。因此，即使从外部对快门施加冲击，快门叶片（2,2'）也不会被无意地打开和关闭。通过偏心销（9）防止保持构件（6）沿错误的方向旋转开关杆（4）的旋转。

摘要： The object detection apparatus of the photoelectric reflection type is comprised of an optical source (2) for generating an optical ray, an optical incident system (3) having an optical axis extending through an observation zone in a direction of its definite observation range for directing the optical ray along the optical axis, and an optical collecting system (5) for collecting the optical ray reflected by the object (4) which traverses the optical axis to focus on a receiving area (6) an optical spot, location of which depends on an axial distance of the object. Further, a definite photosensor is disposed to cover a part of the receiving area and operates only when an object enters into the observation zone within the observation range for detecting an optical spot within the covered part of the receiving area, and an output circuit is connected to output an object detection signal only when the photosensor detects the spot. Preferrably, the definite photosensor has a sensing face extending between one edge registered with a spot which corresponds to the farthest end of the observation range and another edge registered with another spot which corresponds to the closest end of the observation range. Further preferrably, the optical source includes a photoemitter for intermittently emitting a pulsive optical ray in response to a sampling signal, and the output circuit operates to produce successively a sampled data according to the intensity of the detected optical ray and to calculate a relative change between preceding and succeeding sampled data so as to output the object detection signal, when for example the object passes between the detection apparatus and a reflective background surface.
