摘要:
A dustproof view finder in which an image formed by an objective optical system is made erect by an image erecting optical system and is observed through an ocular optical system as an erect image, the optical system including a pair of front and rear optical elements spaced from one another at a predetermined distance to define an aerial space therebetween, and a seal member which encloses the aerial space.

A camera is provided having a finder optical system, a photographing optical system separate from the finder optical system, and a macro photographing mode. The camera includes a movable field frame which is normally located at an inoperative position in which it is retracted from an optical axis of the finder optical system, and which is moved to an operative position in which the movable field frame is in the finder optical axis in association with the transfer into the macro photographing mode. The movable field frame is provided with a field opening corresponding to a photographing range of the photographing optical system.
摘要:
A finder apparatus for use with a lens-shutter type camera composing a zoom imaging optical system, a zoom finder optical system separate from said zoom imaging optical system, and an electronic flash device. The zoom finder optical system is made as a real-image zoom finder apparatus, with part of the associated optical elements being disposed behind the electronic flash device, and part of the optical path from the objective lens to the eyepiece being bent backward of the electronic flash device to pass through the optical element disposed behind the electronic flash device.

A Kepler-type erect image viewfinder includes a first prism having an emergent surface being formed of a spherical or an aspherical surface and having a positive power. A second prism has an incident surface being formed of a spherical or aspherical surface and also having a positive power. The emergent surface of the first prism is spaced apart from the incident surface of the second prism, with an image-forming plane being positioned closer to the incident surface of the second prism than the emergent surface of the first prism. This arrangement enhances image magnification and compensates for field curvature, while simultaneously allowing for the viewfinder to have a reduced overall length.

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.
摘要:
A vehicle seat device in which a seat can be simply and reliably held at a storage position. In a vehicle seat, a vehicle width direction outer side end portion of a seat cushion is supported so as to be capable of rotating around a drive shaft having an axis along a vehicle front-rear direction, and the seat cushion can be switched between a seating configuration at which an occupant can be seated and a storage configuration at which the seat cushion stands erect along a vehicle cabin inner side surface, due to being rotated around the drive shaft by a driving motor. Further, the vehicle seat which is in the storage configuration is held at the storage configuration by a striker.
