A wheel supporting mechanism for adjusting height of a housing supported by the wheels is provided. The wheel supporting mechanism includes wheels supporting a housing; an axle extending from each of the wheels; a wheel mounting member, which has a bearing rotatably supporting the axle, and which has a first end portion and a second end portion; a pivot supporting portion, which pivotally supports the wheel mounting member in relation to the housing; a pivot restriction member that restricts pivoting of the wheel mounting member by being engaged with a vicinity of the second end portion; and an adjustment member that adjusts a height of the housing in relation to the wheel by restricting a pivoting range of the wheel mounting member by connecting the pivot restriction member to the housing.
摘要:
Provided is a method for image formation capable of stably outputting high-quality images with no image density unevenness for a long period of time, in which the images formed are free from image defects of edge deletions and other deletions therein and which ensures good and uniform developability everywhere in the latent image region to be developed with preventing the latent image support used from being degraded. The method includes a step of forming a latent image on a latent image support, a step of developing the latent image on the latent image support with a two-component developer on a developer support disposed to face the latent image support, and a step of transferring the thus-developed toner image onto a transfer medium, wherein the developer support is a cylindrical sleeve having a diameter of at most 20 mm or the latent image support is a cylindrical sleeve having a diameter of at most 40 mm, and the resistance of the two-component developer is at least 1013&OHgr; in an electric field of 2 V/&mgr;m.

摘要:
The present invention provides toner for an electrostatic latent image developer, said toner being excellent in fluidity, chargeability, developability, transferability, and freedom from fogging on a photoreceptor and contamination of the interior of a developing device. The toner for an electrostatic latent image developer comprises spherical toner particles characterized by a shape index ML.sup.2 /A of less than 125 and has a correlation coefficient between X.sup.2/3 and Y, obtained by linear regression with respect to a straight line which passes through the origin of coordinate axes, of more than 0.6 where X is the light emitting voltage due to the carbon derived from the binder resin of the toner particles and Y is the light emitting voltage due to the element derived from the external additive.

By addition of polyglutamic acid or an edible salt thereof, in the case of breads and cakes, the baked volume is increased, an elastic and delicate grain of crumb is assured and a moist texture is provided, in the case of cookies and biscuits, a minimum of dimensional change on baking and a less stodgy texture are assured, in the case of noodles, the body and firm texture are increased and the dissolution of solid matters into boiling water is decreased.
摘要:
The present invention is directed to an operation detecting device of a camera for detecting the operation of an operation member such as the shutter member. The operation detecting device functions by detecting the electrical signal produced at the time at which a closed magnetic circuit is opened when a magnet operates so as to actuate or release the operation member.
摘要:
A manually operable or automatic film speed setting system adapted for use in an electronic exposure control apparatus of a photographic camera. When a film cartridge having an electrically conductive marker representative of the sensitivity of film therein is loaded in the camera, information representative of film speed is automatically introduced into the exposure value computer regardless of the manually switched position of the inherent film speed dial different from that for the sensitivity of the used film.
摘要:
A photographic device includes means for automatic control of the quantity of light from an electronic flash by comparing the brightness of a main object to be photographed with the brightness of a sub-object to be photographed, and the shutter of the camera opens during the time in response to the brightness of a sub-object to be photographed.
摘要:
An exposure control device for a single lens reflex camera has an exposure calculating mechanism for determining the amount of exposure in accordance with desired shutter time, aperture value, film sensitivity and brightness of the object to be photographed. The exposure calculating mechanism is carried along one external wall of a casing for the reflex mirror of the camera.
摘要:
A shutter release system for a camera having an electric shutter, made so that when a power source battery is exhausted preventing a shutter control circuit from properly functioning, it is detected to block shutter release and an electric control mode is changed over to a mechanical control mode by handling a change over means for conducting an exposure with a constant period of time.
