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: A data reading and writing apparatus reads such data as a photographic mode and the number of prints from a magnetic recording portion of a film. The apparatus can change the data and record the changed data onto the magnetic recording portion of the film.

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.

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 fixing device has a hollow fixing roller, and a pressing roller pressingly contacting the fixing roller to cooperate with the fixing roller to form a nip portion therebetween so as to fuse and fix a toner image onto a recording paper. The fixing device also has a heating element arranged within the fixing roller at a position eccentric from the axis of the fixing roller toward the nip portion, to locally heat the inner wall of the fixing roller at a position corresponding to the nip portion, so as to decrease the time necessary to heat the fixing roller, to prevent offset, and to prevent the recording paper from being wound onto the fixing roller.

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.

With such a control, a sorting mode process is prohibited when a required transfer sheet is one irrespective of whether the number of sheets of original is one or not.
