摘要： An electronic weighing apparatus comprises a slit plate provided to be displaceable in association with the weight of an article being placed on a weighing pan. A photosensitive device is provided in the vicinity of the split plate for generating a train of pulses responsive to the slits in association with the displacement of the slit plate. The slits are provided on the slit plate such that the pulses are obtained from the photosensitive device only if and when the amount of displacement exceeds that corresponding to a predetermined weight value. The slit plate is further provided with a magnetic shield plate at the position before the photosensitive device detects the slits for the first time when the slit plate is displaced by virtue of an article. A permanent magnet and a reed switch are provided to be faced to each other through the slit plate at a mechanical zero point position, such that the reed switch is turned on if and when the slit plate is displaced and the magnetic shield plate is removed from the mechanical zero point position, whereby various components of the electronic weighing apparatus are energized by a battery. The pulse train obtained from the photosensitive device is counted by an up/down counter, which is initially loaded with the data associated with the above described predetermined weight value when the reed switch is turned on. Accordingly, the up/down counter starts a count operation of the pulse train, starting from the above described initial count value associated with the above described predetermined weight value.
摘要翻译：电子称重装置包括狭缝板，该狭缝板设置成与被放置在称重盘上的物品的重量相关联地移动。在分隔板附近设置感光装置，用于与狭缝板的位移相关联地产生响应于狭缝的脉冲串。狭缝设置在狭缝板上，使得只有当位移量超过对应于预定重量值的位移量时，才从光敏装置获得脉冲。狭缝板还在光敏装置利用物品移动狭缝板之前第一次检测到狭缝之前的位置处设置有磁屏蔽板。永磁体和舌簧开关在机械零点位置处通过狭缝板彼此相对设置，使得当狭缝板移位并且磁屏蔽板被移除时，舌簧开关被接通机械零点位置，由此电子称重装置的各种部件由电池供电。从感光装置得到的脉冲串由上/下计数器计数，该计数器在簧片开关导通时首先加载与上述预定重量值相关联的数据。因此，上述上下计数器从上述与上述预定重量值相关的初始计数值开始，开始脉冲序列的计数操作。

摘要： System for providing a digital indication of the load on a scale, utilizing a relative position transducer to produce two output signals which vary between fixed levels in response to incremental displacements of the output indicator of the scale. The two signals are phase encoded in that one of the signals leads the other, depending upon the direction of displacement. The two signals are processed to determine the occurrence and direction of each increment of displacement, and the count in a digital counter is incremented or decremented in response to each increment according to the direction of the displacement.

摘要： A spring weighing scale includes an optical detector which generates a moire fringe pattern and moves the pattern as an optically amplified function of scale tare deflection. A first of a pair of parallel optical gratings moves with a scale tare structure, while a second reticle grating remains fixed. Passing through both gratings is a light beam which projects a fringe pattern upon a photodetector array. Placement of a load upon the scale results in movement of successive fringes across the photodetectors and the sequential generation of weight indicative signals which are counted to determine load weight. Automatic zero load adjustment is effected by a displacement linkage driven by a stepping motor to provide displacement of the photodetector array along the axis of pattern movement. The motor is controlled by a counter monitor to register the photodetector array with the pattern image no load position such that a null count is produced. The linkage employs a twin parallel threaded worm and socket to provide any requisite compensatory shift of a chassis which carries the photodetector array. In a further embodiment, the photodetector chassis is supported by a pair of parallel leaf springs which bias the chassis against an adjustment worm driven by the motor. Alternately, a sine bar sliding wedge is worm driven against the bias of the leaf springs to displace the chassis.

摘要： An electro-optical encoding device comprising a moveable member having a characteristic coded pattern of intermixed light reflecting and nonreflecting stripes representative of data to be electrically encoded. An electro-optical monitoring assembly is positioned adjacent the path of movement of the coded moveable member for serially illuminating the coded pattern of light reflecting and nonreflecting stripes with an interrogating light beam as the moveable member moves past the electrooptical monitoring assembly. The electrooptical monitoring assembly also includes an arrangement for serially receiving back pulses of light returned by the coded pattern of light-reflecting stripes and deriving serially coded output signals which are representative of the data encoded on the side of the moveable member. The electrooptical monitoring assembly comprises a source of illumination, a first optical subassembly for directing light from the source of illumination onto the characteristic coded pattern of light-reflecting stripes formed on the sides of the moveable member, a second optical subassembly for receiving light pulses reflected back from the pattern of light-reflecting stripes and for directing the received light pulses to the photosensitive surface of an electro-optic converter such as a photocell for converting the intelligence contained in the received light pulses into coded electrical signals representative of the data encoded on the moveable member.

摘要： An electronic weighing apparatus includes a switch mounted on a base surface thereof, actuated by an actuating member biased to support a portion of the base. When weight is applied to the apparatus, the actuating member is moved to a depressed position, thereby automatically energizing the apparatus. In addition, a tab is mounted to the base near the switch. Vertical forces can be applied to the tab to depress the actuating member without disturbing the zero position of the weighing apparatus.Furthermore, the apparatus includes an optical coded disc with a plurality of concentric code tracks. A light guide conducts light to a line on the disc which is parallel to but offset from a radius of the disc. Photosensors are positioned on the other side of the disc, opposed to the light guide. A mask is interposed between the photosensors and the light guide, which mask defines a plurality of apertures, each of which is oriented parallel to a radius of a respective code track such that no two of the apertures are parallel.
