摘要:
The disclosed light measurement compensation device for a camera includes the known resistors for aperture correction and for curvature correction in order to compensate for the error of light measurement in the full open aperture light measuring mode. The device also includes a resistor for compensating for the light measuring output difference present between two light measuring modes, or partial light measuring mode and average light measuring mode, and another resistor for shifting the light measuring output by a prescribed quantity. For this reason, even though the various light measuring modes, namely, full open aperture-average light measuring, stop down-partial light measuring, full open aperture-partial light measuring, and stop down-average light measuring modes, are selectively used, either an erroneous display or a drop of the exposure accuracy seldom takes place.

The disclosed light measuring arrangement is positioned to receive and measure light from a focusing screen on which a display of focusing conditions is superimposed. A correcting circuit corrects the object brightness sensed by the light measuring arrangement. When display segments of the display are selectively switched on and off, the correcting circuit produces an output signal representing a corresponding brightness correction factor which is applied to the light measuring arrangement.

The disclosed camera includes a view finder whose visual field displays a mark indicative of a focused condition. A display which extinguishes the mark either immediately after the detection of the in-focus condition or a predetermined time after the detection of the in-focus state condition, and generates an audible or visual mark outside the view finder's visual field.

A camera is arranged such that when a film housed in a film cartridge is loaded into a film cartridge chamber of the camera with a leader portion of the film remaining outside the camera and upon closure of the film cartridge chamber, the leader portion of the film is retracted into the camera and the film is wound onto a film winding spool. This camera comprises a retracted-amount measuring system for measuring the retracted-amount of film when the leader portion thereof is retracted into the camera and a wound-amount detector responsive to an output of the retracted-amount measuring system to determine the amount of the film wound onto the film winding spool.

A toilet system (10) with urine assay function is disclosed which comprises a toilet stool (12) having a toilet bowl (14) and a small urine-sampling cavity (52). A frame (42) is mounted on the toilet stool to support a testing sheet handling and transfer mechanism (30) which comprises a swingable carriage (46) and a slidable arm (50) supported by the carriage for linear telescoping movement. The carriage is swingable about a vertical axis (48) between a first position in which the carriage is oriented toward the sampling cavity and a second position in which the carriage is oriented to a lateral side of the stool wherein a disposal station is provided.The toilet system enables the use of testing sheets (32) which are made from water insoluble materials.Various other embodiments are also disclosed.The system provides a high degree of reliability of analysis.

The film loading date memory storage device of a camera which includes a film winding spool, a clock device for counting the present date and time; a store for storing the date information obtained at the clock device when the camera is loaded with a roll of film; and a display which displays the information on the film loading date stored at the store. The device is provided with film loading date detecting device which produces and supplies a film loading date signal to the store by detecting that the leader part of the film is taken up on the film winding spool.

The present patent application discloses a blank film advance control device for a camera, in which when the film loading cover is closed, the film is automatically advanced a prescribed number of blank frames. The device is provided with means for memorizing the fact that the advancing of the blank frames has completed and means for coordinating the memorizing means with the film loading cover to restore the memorizing state of the memory means at least until the film is rewound. With this, even if the film loading cover is accidentally opened and closed again after the end of the blank film advance, the camera is prevented from performing faulty operations, for example, a second cycle of blank film advance. Instead, it carries out a proper different operation from the first cycle of blank film advance which took place after the film loading cover was closed for the first time.
