In a case in which the photometry region selected through a photometry region selection part is in the center of the screen, body spot photometry is selected for photometry of the object field, using luminous flux not passing through the screen. In all other cases, an output is selected for photometry of the image of the object field formed on the screen.

A lifting mechanism is arranged between a cartridge main body and a reel support member. With the cartridge main body set in a parts mounter, the lifting mechanism allows the reel support member to be supported by the cartridge main body so that the reel support member can be pivoted upward at a predetermined pivoting angle (set position PA.fwdarw.bar code read position PB). While cartridges are kept placed in the parts mounter, a parts supply reel attached to a given cartridge is made to project from other reels. This enables a bar code reader to read the parts code of a label adhered on one side surface of that reel.

An exposure calculation device for use in a camera, is provided with a light metering device for effecting light metering in each of plural areas divided in the object field and generating a light metering signal, containing information relating to the color of the object in each area. A first judgment device judges, whether the object in each area is colored or uncolored, based on the light metering signal and determining colored areas in which the object is colored and uncolored areas in which the object is uncolored; A second judgment device judges whether a predetermined uncolored area contains a white or black object, based on the light metering signals from the colored areas and those from the uncolored areas; An exposure value determining device determines the exposure value according to the light metering signals, based on the results of judgment by the first and second judgment devices.

This invention relates to a camera photometry system which uses accumulation-type photoelectric elements to output photometry information related to the brightness of the subject field. Its purpose is to provide a camera photometry system which has a simple structure and which contains a two dimensional photometry mechanism with a wide dynamic photometry range. A camera photometry system using this invention is composed of a two dimensional photometry mechanism made of multiple accumulation-type photoelectric elements, and an accumulation control mechanism which controls the accumulation time of the photoelectric elements, with the system structured so that the multiple photoelectric elements are grouped in separate areas and the accumulation control mechanism is positioned at each of these areas and controls the accumulation time of the photoelectric elements in each separate area.

The invention provides a camera photometry system that uses accumulation-type photometry elements to output photometric information related to the brightness of the subject field. The invention eliminates the smear phenomenon caused by the effects of the brightest parts of the subject field while also appropriately measuring the light of the major subject in the subject field. The invention is a camera photometry system equipped with a photometry mechanism which measures light using accumulation-type photoelectric elements by dividing the subject field into multiple photometry regions, and which outputs photometry information related to the brightness of the subject field, with the photometry element being equipped with a photoelectric mechanism for converting light into electricity which is stored and a transmission mechanism for transmitting the electric charge which is stored by the photoelectric mechanism. The system is configured so that the transmission mechanism transmits the electric charge from the top to the bottom with respect to the vertical direction of the subject field.

In a portable radio communication apparatus comprising an insulating case having an inner surface and a printed board housed in the insulating case, an antenna conductive film is coated on a predetermined region of the inner surface of the insulating case. A conductive ground film is coated on the remaining region of the inner surface of the insulating case with a constant gap from the outer periphery of the antenna. A first conductive member connects the antenna film with the conductive ground film. A plurality of second conductive members connect the conductive ground film with a ground pattern of a radio communication circuit on the printed board. A feeding member connects the antenna with an antenna terminal pad of the radio communication circuit. The second conductive members and feeding member are conductive rods.
