    摘要： In an image forming apparatus, a developing device is disposed adjacent to a belt-like photosensitive member. A rotary type developing device has a hollow cylindrical casing rotatable around a shaft having a central portion for rotation. The developing device includes a casing which is rotated in a predetermined direction, and four partitions which divide the casing to make four developing units which extend radially outward from the shaft. A toner storing section or hopper is provided on one side of the developing device, i.e., on a front side of the image forming apparatus, and a toner cartridge is detachable from a top of the hopper, and the toner cartridge is exchanged when an end signal of the toner is detected by a sensor in the casing. The toner hopper is filled by new toner from the toner cartridge, and the toner is carried by conveyor members, which control an amount of the toner in the casing, and a supply roller supplies the toner to a developing roller. Therefore, the device supplies a required amount of toner to a toner supply roller and a developing roller at all times. This provides an image forming apparatus with a great freedom of layout which needs a minimum sectional space relative to a photoconductive element and which, therefore, has a miniature configuration. Also, if amounts of transport of first and second conveyor members are adequately selected, a uniform developer distribution in a longitudinal direction without resorting to a complicated control is insured.

    摘要： A frequency converter is provided of which a frequency-dividing ratio is arbitrarily altered and retained after a power is turned off. The frequency converter has a programmable counter which outputs a signal having a desired frequency, a non-volatile memory for storing data for setting the frequency-dividing ratio and a control unit for controlling a writing operation of data stored into the non-volatile memory. The programmable counter, the non-volatile memory and the control unit are accommodated in a single package. The frequency converter may comprise a resonator and an oscillating circuit within the package so that the frequency converter can be treated as a single frequency generator such as a quartz-crystal oscillator.

    摘要： An apparatus and method for detecting an empty condition of toner cartridges containing toner for copiers, fax machines, printers and the like is disclosed. The cartridges may be mounted to a rotary developing device. According to one embodiment, when a toner cartridge has been rotatably positioned to a developing position, an empty condition is detected by emitting light into the toner cartridge and detecting the light coming out of its bottom. To accomplish this detection, a light source and a light sensor are fixedly located near a bottom corner of the toner cartridge at the developing position. Light is emitted into the toner cartridge at a predetermined oblique angle with respect to a side wall of the toner cartridge. Light exits out from the bottom wall if a predetermined amount of toner does not exist in the toner cartridge. Due to the oblique angle, the distance between the light source and the light sensor is substantially reduced and provides an accurate measurement. This reduced distance also results in a smaller end detection system.

    摘要： An electrical connector includes a frame, a connector main body received in the frame, a lock, a lock receiving part, and a releasing tool. The lock is formed on the frame or the connector main body, while the lock receiving part is formed on the other of the frame or the connector main body, corresponding with and engaging the lock. The releasing tool releases the lock that is engaged with the lock receiving part when the releasing tool is inserted the frame and the connector main body. The releasing tool disengages the lock and the lock receiving part when inserted in to the frame and connector main body, and then pushes the releasing tool receiving surface to separate the connector main body from the frame.

    摘要： A line head driving apparatus includes a correcting circuit which sets an electrical energy level to be applied to thermal elements to be greater than that indicated by multilevel image data supplied from a preprocessing circuit when a series of multilevel image data indicates an increase in an image density in a sub scan direction perpendicular to the main scan direction. On the other hand, the correcting circuit sets the electrical energy level to be applied to the thermal elements to be less than that indicated by the image data supplied from the preprocessing circuit when the series of multilevel image data indicates a decrease in the image density in the sub scan direction. The line head driving apparatus also includes a head driving circuit which drives the thermal elements in accordance with the electrical energy level set by the correcting circuit.
