A method and device for checking a joint of an electronic component is arranged to apply heat energy to a joint containing a heat conductive material and receive the infrared ray radiated from said joint with an infrared camera. By processing the image information output from the infrared camera, the method and device can offer an area of a defect, an area ratio of a defect, pixel coordinates, a temperature distribution pattern, a distance between central axes of a particular portion of the joint, or a gradient angle. The obtained value is compared with a predetermined value for determining the kind of a defect and whether or not the joint is defective.

An image forming apparatus comprising first and second developing units each of which has detector for detecting toner density in the developing unit, input member for inputting toner replenishment instructions to each of the first and second developing units, and first and second replenishing members provided respectively to the first and second developing units for replenishing the toner in response to the input of the toner replenishment instructions by an operator. One of the first and second developing units is selected by the operator upon the copying. In this image forming apparatus, the replenishing members replenish the toner to the first and second developing units having toner densities of less than a predetermined value irrespective of the selection of the developing units.

A plurality of lead wires such as those from an IC (an integrated circuit) is irradiated by a fan beam at same time. Infrared rays radiated from the portion which is irradiated by the fan beam and the periphery of the portion are detected so as to catch a thermogram exhibiting the temperature distribution. The thermogram is processed by image processing so as to produce a temperature distribution image. This image is visually compared with a standard temperature distribution-pattern on a display apparatus to judge whether soldering on those lead wires is defective or not.

Junction inspection method and apparatus for electronic parts

A control apparatus for controlling concentration of toner incorporated in developing material in a developing unit by means of controlling a toner replenishment to supply the toner in accordance with a toner concentration detected by a toner concentration detecting sensor in a first state wherein the detecting signal of the sensor is normal and to supply the toner by a constant volume at the predetermined period in a second state wherein the detecting signal of the sensor is abnormal.

An automatic paper feeder presses the surface of copying paper loaded on a paper loading plate in a paper cassette against a paper feeding roller, and feeds the paper sheet by sheet in accordance with the rotation of the roller. When a paper detector provided at a downstream side of the roller does not detect the paper within a specified period of time after starting a paper feeding operation, the automatic paper feeder rotates the roller in the reverse direction, at the same time releasing the pressure between the paper and the roller, and then increases the pressure and rotates the roller in the forward direction to restart the paper feeding operation.

Automatic paper feeder

A developing apparatus which includes a toner replenishing device for replenishing toner into the developing apparatus, a toner concentration detecting sensor for generating an output coresponding to the toner amount in a developing material stirred and transported through the developing apparatus, with the output containing a varying output periodically produced and stable output, a discriminating element for deriving the stable output of the outputs from the toner concentration detecting element, and a comparator for outputting a feeding signal to the toner replenishing device through comparison between the output from the discriminating element and a preliminarily set reference value.

Toner concentration control device for a developing apparatus

A copying apparatus comprises a document glass, an automatic document feeder that is free to be opened and closed with respect to the document glass, a paper feeding means, means for storing image formed papers and an image forming means. The image forming means is operable in a special paper-passing mode that permits the transfer paper to be ejected into the storing means without having the image formed thereon. The copying apparatus is provided with means for detecting the open and close actions of the automatic document feeder so that an alarm can be issued to remind the operator of the document left on the document glass according to the signal issued by the detecting means after the operation of the image forming means has been completed, and the operation of the alarm means can be inhibited after the operation of the image forming means in said paper-passing mode has been completed.
