摘要:
An electro-developing type camera using an electro-developing recording medium on which an image is developed while an electric voltage is applied thereto. The image is read out from the electro-developing medium by a scanning mechanism. A color separation filter is disposed in front of the recording medium, so that R, G and B images are recorded on first, second and third recording areas, respectively. The color separation filter and the recording medium are disks rotatably provided. A photographing optical system is disposed at a first position at which the optical axis thereof is positioned above the rotational axes. The scanning mechanism is disposed at a second position at which the scanning mechanism is positioned under the rotational axes of the electro-developing recording medium and the color separation filter. Each of the recording areas is positioned above the rotational axes when a photographing operation of the recording area is carried out, and is positioned under the rotational axes when a reading operation of the image from the recording medium is carried out.

A view finder device has a Poro prism and a first optical system facing an emergent plane of the Poro prism. The first optical system is positioned beside the Poro prism and opposite to a recording medium passage through which an electro-developing recording medium is moved. A relay optical system is provided behind the recording medium passage, so that the eye point of the view finder is separated from the first optical system. A second optical system is provided behind the relay optical system, so that the image formed by the relay optical system is observed. Since the electro-developing recording medium can be moved between the first optical system and the relay optical system, the finder optical system can be disposed at a lower position.

A zoom finder is provided and includes a lens group for producing a field flattening effect for correcting a curvature of field. The zoom finder includes an objective optical system of a positive power having a first lens group of negative power, a second lens group of positive power, a third lens group of positive power, and an eyepiece optical system of positive power through which an image formed by the objective optical system is observed. The first lens group, the second lens group, the third lens group and the eyepiece optical systems are arranged in this order from an object side. The second lens group of the objective optical system is movable in an optical axis direction to vary the power, and the first and second lens groups are movable in association with each other in order to keep a constant diopter.

This invention provides a viewfinder which is mounted separately from a taking lens on a camera and wherein the occupying space of a parallax-correcting prism is minimized to arrange freely its optical design. And also, this invention provides a viewfinder decreasing the difference of the diopter and the fuzziness of the image between normal photographing mode and macro photographing mode. To achieve these objects, this viewfinder comprises a prism arranged in the optical path of said viewfinder to correct the parallax, and a driving mechanism to slide said prism in the direction normal to the axis of said lens system.

An electro-developing type camera has an electro-developing recording medium for recording and developing an optical image formed thereon. A conductive electric-charge-eliminating brush is provided to establish electrical contact and physical contact with the recording medium. The electric-charge eliminating brush eliminates an electric charge from the recording medium due to the electrical contact between the brush and the recording medium, and removes particulate matter such as dust from the recording medium due to the physical contact between the brush and the recording medium.
摘要:
An image recording device mounted on an electro-developing type camera using an electro-developing recording medium in which an object image obtained through a photographing optical system is electronically developed. The electro-developing recording medium has a first recording area in which the image is recorded, and a second recording area in which information other than the image is recorded. First and second electrodes are provided in the first and second recording areas, respectively, so that an electric voltage can be independently applied to the first and second recording areas. By exposing the first recording area while applying the voltage thereto, the image is recorded in the first recording area. By heating the second recording area without applying the voltage thereto, the information is recorded in the second recording area.
摘要:
In a new printer, a toner cartridge is mounted in the state where there is no toner in a reserve tank, and toner of the amount of filling toner D therein is supplied with the amount of full accommodation toner E for filling up the reserve tank by a toner supply mechanism. The toner of the amount of remaining surplus toner F remains in the toner cartridge. The amount of toner consumption G is measured by a dot counter during a printing execution. In the case where a toner density sensor detects a toner decreasing, the toner is supplied to a developing unit from the reserve tank. When it becomes G>F, it display-informs a user of “toner cartridge exchange is allowed”. Hereby, it enables to exchange the toner cartridge without stopping operation of the main body of the image forming apparatus using a two-component developer.
