摘要:
A surveying apparatus is provided that includes a sighting telescope, an imaging device, and an external orientation parameter calculator. The sighting telescope is rotatable about a horizontal axis and a vertical axis. The imaging device is integrally rotated with the sighting telescope and the imaging device has an optical axis that is different from the collimation axis. The external orientation parameter calculator calculates external orientation parameters of stereo images that are obtained by the imaging device in an erecting observation and in an inverse observation in terms of the position of the optical axis with respect to the collimation axis, and the sighting directions in the erection observation and in the inverse observation.

The invention provides a color image forming apparatus with photoreceptor belt. In a roll of the photoreceptor belt provided two pieces of rotatable rollers and guide plate with a curved surface so that the photoreceptor belt is moved while slidably coming in contact with the curved surface of the guide plate. Along the outer surface of the roll of the photoreceptor belt provided a plurality of developing devices at the curved surface to form a color toner image on the photoreceptor belt.

A color image forming apparatus wherein a photosensitive belt trained around a plurality of rollers is moved along a guide member, and the guide member is in contact under pressure by an elastic member with a space retaining member provided in each of image forming members facing the photosensitive belt. A color image forming apparatus wherein a photosensitive belt trained around a plurality of rollers is moved along a guide member, and each of given space retaining members is mounted coaxially with each of developing sleeves in the developing devices is in contact under pressure with the side end of the guide member facing the photosensitive belt by an elastic member.
摘要:
A developing apparatus having a developing roll including therein a developing sleeve and a magnet roll to be faced to an image retainer for developing an electrostatic latent image on the image retainer with a developer. A partition plate is provided between developer agitating members disposed below the developing roll. A developer removing device for removing the developer on the developing sleeve is provided on an upper portion of the partition plate.
摘要:
An image forming apparatus wherein a recording paper receiving cassette can be moved to a first position where the cassette is stored in the apparatus body and a second position where one portion of the cassette is withdrawn from the apparatus body so that the paper feed can be carried out, wherein when the cassette is withdrawn further from the apparatus body the cassette can be removed from the apparatus body. A process cartridge including a photosensitive belt and a plurality of developing devices are arranged around the photosensitive belt. The process cartridge is disposed above the recording paper receiving cassette, wherein the process cartridge can be withdrawn in the same direction as that of the recording paper receiving cassette when the recording paper feed path is opened.
摘要:
A color image forming apparatus wherein a belt-shaped image retainer faces an image forming device. The image forming device includes a charging device, exposure device and a plurality of developing devices which are juxtaposed with each other. The belt-shaped image retainer is in the form of a cartridge which is mounted removably in the apparatus body. The cartridge has a closable cover divided into several sections which are arranged at the positions facing the image device. The belt-shaped image retainer has a transversely movable shutter member for protecting spaced apart surface portions of the image retainer which would be otherwise exposed when the upper casing of the apparatus body is opened or when the image retainer is removed from the upper casing, by moving the shutter member transversely to cover the spaced apart exposed surface portions of the image retainer.
摘要:
A color image forming apparatus having an image retainer, a cleaning device for removing residual toner particles on the image retainer, and a device for releasing the cleaning device from the image retainer, which are integrally constructed as a process unit and can be taken out from an apparatus body. The cleaning device is in pressure contact with the image retainer when the process unit has been taken away. The device for releasing the cleaning device is mounted on the apparatus body.
摘要:
A color image forming apparatus has a plurality of developing devices and an automatic paper feed unit and a manual paper feed unit, each paper feed unit having a paper feed cassette. The paper feed units are provided below a belt-shaped image retainer. Paper ejection ports are provided above the image retainer for ejecting transfer materials which are fed from a paper feed unit, one of the paper ejection ports being selected according to the thickness of the transfer material. A thermal fixing condition is varied according to the transfer material thickness.
摘要:
An electrostatic image forming apparatus for forming a color image wherein plural developers are located substantially under the image retainer, at least two of the image retainer, the developer, and the cleaner being formed as a detachable unit.
