摘要： An image forming apparatus has an image bearing member; toner image forming unit for forming a toner image with non-magnetic toner on an image bearing member; intermediate transfer member contactable to the image bearing member and movable along an endless path; primary transfer unit for effecting primary image transfer of the toner image formed on the image bearing member onto the intermediate transfer member at a first transfer position; secondary transfer unit for effecting a secondary image transfer of the toner image from the intermediate transfer member on the transfer material at a second transfer position; and a residual toner charger for charging the residual toner remaining on the intermediate transfer member to a polarity opposite from a regular polarity thereof. After the secondary image transfer, the residual toner remaining on the intermediate transfer member is charged by the residual toner charger to the opposite polarity, and is then passed through the first transfer position during the primary image transfer, so that the residual toner is transferred back to the image bearing member substantially simultaneously with a next primary image transfer, thus removing the residual toner from the intermediate transfer member.

摘要： A camera capable of operating in a standard or a panoramic photography mode is provided with an automatic focusing system that focuses on a subject in one of a plurality of areas within a photographic field. In the standard photography mode, the camera automatically selects one of the plurality of areas based on a predetermined algorithm and focuses on the selected area. In the panoramic photography mode, the camera selects one of the plurality of area in response to a user performed operation and focuses upon the selected area. When operating in the panoramic photographic mode, an area can be selected by using a manual selection device, or through use of a visual line position detection device. The visual line position detection device determines which area in the photographic field the photographer's eye is focused upon, and the focused upon area is then selected. The camera may include a display device that indicates which of the plurality of areas has been selected.

摘要： In a camera system including an electronic flash apparatus, a main capacitor of the flash apparatus is charged for a predetermined time interval, in response to a preparatory operation such as a first stroke of a release button. During this time interval, operation of an automatic distance measuring device, an automatic exposure controlling device and an object luminance discriminating circuit is prevented. A warning device warns a photographer that the main capacitor is insufficiently charged. Several voltage detectors detect different voltage levels of the main capacitor and produce detection signals for inhibiting the operation of the warning device and/or preventing further charging of the main capacitor.

摘要： A camera with a visual line position detection device is capable of shortening the time required for auto focus detection and capable of more accurate selection of the focus detection point. The camera includes a focus detection device to output the results of distance measurements at a plurality of points where focus detection is possible and to detect focus for one of these points. A liquid crystal display device displays on a screen specified symbols overlapping the subject image on the positions corresponding to each of the points. A microprocessor accepts the results of the distance measurements from the focus detection system and selects one of the points based on the photographer visual line position as the point for focus detection among all the points whose distances are measured and on which focus detection is possible, excluding the points with an infinite focus distance.

摘要： The operating mode contents of a camera can easily be set by the visual alignment action of the photographer and by manual operation. In a first embodiment, a camera is equipped with a visual line position detection device that detects the position of the visual line of the photographer, a mode contents setting device that sets the contents of the operating modes, and a control device that, when it is determined from the output of the visual line position detection device that the photographer is aligning his vision on a predetermined area, changes the camera mode of the mode contents setting device. In a second embodiment, it is possible to quickly switch the camera mode that is the object of manual operation to the object of the visual alignment operation. It is then possible to change the contents of the mode through the visual alignment action, constituting the manual operation in the second embodiment. A selection device is started through the operation of an operation device, such as a mode switching device, and accomplishes a process wherein the camera mode set through manual operation using a mode setting device is set as the camera mode that is the object of contents changing through the action of visual alignment on numerical value setting areas.
