Abstract: A photographic color temperature meter capable of measuring light including stationary light and flash light. The meter controls timing of light measurements so that light measurement is performed during the time when stationary light and flash light are included and when only stationary light is included. Thereafter, calculation of color temperature only of flash light is performed.

Abstract: A copying machine for forming an image by scanning a laser beam which is emitted from an optical system on a photosensitive member. Photosensors are provided at optically equivalent positions to a beginning portion and an end portion of a scanning line on a photosensitive member. A scanning time of a laser beam in the main scanning direction is measured by these photosensors. The measured time and a standard time for a copy magnification set by an operator are compared, and a correction value is calculated, and at the same time, magnification in the main scanning direction is corrected using the correcting value. Also, focusing (adjusting of the beam diameter) is carried out using the photosensors. Each of the photosensors contains a photoelectric transfer element, and a beam which comes through a slit is incident to the element. Each photosensor is provided with two slits. One is perpendicular to the main scanning direction, and the other is inclined to the main scanning direction.

Abstract: A camera comprises an angular velocity sensor for detecting camera-shake. The angular velocity sensor takes a certain time to be stabilized after its operation is started. When correction of camera-shake is required during the certain period, it is displayed that correction of camera-shake is not possible.As a result, a photographer using the camera with the camera-shake detection sensor refrains from photographing when correction of camera-shake is not possible.

Abstract: A camera has an electronic viewfinder for displaying an image of a subject to be photographed in accordance with image data from a scene. The displayed image encompasses an area larger than that of the scene to be photographed, to enable the camera user to view objects and events outside of the photographic frame. In addition, the image data can be processed in accordance with differing photographic conditions, such as changes in shutter speed, aperture or electronic flash emission, to permit the user to view the changes that occur under the differing conditions.

Abstract: An image forming apparatus includes a feeder for feeding a new paper accommodated in a feeding cassette, an image forming device which forms an image on the paper fed by the feeder, an intermediate container which temporarily accommodates the paper fed by the feeder and having the image thereon, a refeeder which refeeds the accommodated paper from the intermediate container to form an image on the paper again, a detector which detects presence or absence of paper to be fed by the refeeder for image formation, and a controller which effects a change-over from the paper feeding operation by the refeeder to the paper feeding operation by the feeder when the detector detects the absence of paper to be refed or forbids the paper feeding operation by the refeeder until the detector detects the absence of paper to be refed after the paper has been accommodated in the intermediate container.

Abstract: An image projecting apparatus for projecting an image recorded in a microfilm incorporated in a cartridge on a screen, for example, is furnished with a loading device which has a container storing a plurality of cartridges detachably attached thereto. The cartridges in the container are sequentially loaded at a prescribed position of a roll film carrier by a loading mechanism of the loading device and subjected to screening of a microfilm for retrieval of a desired image. The cartridge containing the microfilm which had undergone the screening is extracted from the prescribed position and returned to the container by a discharge mechanism. The discharge mechanism returns the cartridge loaded at the prescribed position via a path independent of the path used by the loading mechanism for moving the cartridge.

Abstract: A charging device and method in which a charging member, for example, of a brush, plate, film or roller type, for charging a charge-receiving member is disposed at a predetermined distance from the charge-receiving member. The distance is adjusted at not greater than a discharge start distance when the discharge is started and is adjusted at greater than the discharge start distance and less than a discharge stop distance after the discharge is started. The discharge start distance is the distance at the start of discharge when two electrodes are in close proximity as a voltage is applied, and the discharge stop distance is the distance directly before a stable discharge stops when two electrodes are separated while in state of discharge.

Abstract: In the printing apparatus wherein the laser diode is used as light source for writing images on an image carrier, a control transistor is serially connected to the laser diode. The magnitude of the drive current for driving the laser diode is adjusted in accordance with the magnitude of the base current of the control transistor. The base current of the control transistor is turned on when the main power supply is implemented. That is, the control transistor is pre-heated up to print command. Consequently, the drive current is stable from the initial image formation after the main power supply is turned on.

Abstract: An image forming apparatus capable of making copies under either predetermined standard copy conditions or copy conditions optionally set by an operator. After the final key input, or at the completion of a copying process, a first timer is set to count a predetermined time period. When the first timer finishes counting, the copy conditions are automatically set to the standard conditions. The above apparatus is provided with a guidance mode for the purpose of explaining the method for setting the functions and copy conditions within the apparatus to an inexperienced operator. In the case where the guidance mode is set by the operator, a second timer is set to count a predetermined time period longer than the time period counted by the first timer. When the second timer finishes counting, the copy conditions are automatically set to the standard conditions.

Abstract: A copying-machine management system for effecting centralized management of a plurality of copying machines in such a manner that data about problems developed during the maintenance of each copying machine is not counted as data about the problem occurring in each copying machine. A control CPU incorporated into a copying machine on the user side is electrically connected to a management CPU on the service station side through a communication line. Thus, a signal indicative of the state of the copying machine on the user side is sent to the management CPU on the service station, where each of the copying machines is managed. When a serviceman is sent to repair the copy machine, a serviceman mode is set. When the serviceman mode is set, the data indicating a problem is prohibited from being transmitted to the management CPU. Therefore, the data about a problem developed due to a reproduction test is not counted as the data about the problem occurring in each copying machine.
