A camera having a television mode has a shutter unit for opening and closing a plurality of shutter blades used as a shutter and a diaphragm by rotating a step motor in normal and reverse directions; a photometric device for performing a photometric operation with respect to a photographed object; a mode switching device for selectively switching a television mode for photographing a picture image on a television screen and a normal mode for performing a normal photographing operation; a trigger switch for outputting an open signal in synchronization with an operation for opening the shutter blades and outputting a closed signal in synchronization with an operation for closing the shutter blades; and a calculator for calculating an exposure amount by photometric information provided by the photometric device when the normal photographing mode is selected by the mode switching device. The calculator converts the calculated exposure amount to a time from a generating time point of the open signal of the trigger switch to a time point of the reverse rotation of the step motor so as to control a program exposing operation with respect to the shutter unit. The calculator calculates the exposure amount by the photometric information provided by the photometric device when the television mode is selected.

In a photoelectric converting apparatus having a plurality of photosensors divided into an opening portion and a light shielding portion, a carrier eliminating structure to block the inflow of photosignals from the opening portion is provided between the photosensor in the light shielding portion and the photosensors in the opening portion. The photosensor comprises of a photoelectric converting transistor having a control electrode region to accumulate the carriers generated by the light excitation. The carrier eliminating structure has the same constitution as that of the photosensor. The potential of the control electrode region is fixed to a constant potential so as to attract the carriers from the opening portion.

An objective is to provide a body measurement device capable of carrying out a body measurement, such as of abdominal girth or chest girth, with a simple configuration which eliminates moving components. This body measurement device comprises: light projection devices which project linear light beams so as to encircle a measurement subject within a measurement plane; image capture devices which are positioned on the perimeter of the measurement subject such that the total circumference of the linear light beams which are projected upon the measurement subject are captured, and the optical axis of each respective image capture optical assembly is positioned in an oblique direction with respect to the measurement plane; a database which, with the measurement plane divided into respective measurement ranges of the image capture devices, associates two-dimensional coordinates with respect to captured images of the image capture devices with two-dimensional coordinates with respect to the measurement plane; and a computing device which, with the measurement plane divided into the respective measurement ranges of the image capture devices, queries the database from two-dimensional coordinates of a point with respect to the linear light beams with respect to the captured images of the respective image capture devices corresponding to the measurement plane, identifies two-dimensional coordinates with respect to the measurement plane, and computes a circumference of a body surface of the measurement subject with respect to the measurement plane.

In a print processing system, a storage server temporarily stores print data generated on a user client PC; a multifunction apparatus then obtains the print data from the storage server and prints the data, according to user's operation on the multifunction apparatus; and a management server manages a storage status of the print data on the storage server. The user client PC transmits to the storage server, bibliographic information associated with the print data concurrently when transmitting the data. The storage server stores thereon the print data obtained from the user client PC and transfers to the management server, the bibliographic information obtained from the user client PC. The management server manages the storage status of the print data on the storage server, based on the bibliographic information obtained from the storage server.

An active vibratory noise control apparatus has a speaker for canceling vibratory noise in the passenger compartment of a vehicle, the speaker being used as a speaker of one of different audio devices that can be installed on the vehicle. Each of the audio devices has a command key switch assembly. When the command key switch assembly is operated to turn off the transistor, a control signal is applied to a switching control circuit in an active vibratory noise control unit, which identifies the audio device installed on the vehicle. The active vibratory noise control unit generates a canceling signal matching characteristics of the speaker of the identified audio device for canceling vibratory noise in the passenger compartment.

A method for manufacturing connectors comprises providing a carrier strip with a plurality of first alignment apertures and a plurality of contacts arranged in a row. The carrier strip is cut to desired lengths to form contact band pieces. The first alignment apertures are engaged with first protrusions on a carrier tape to mount each of the contact band pieces to the carrier tape. The first protrusions have a smaller outer diameter than an inner diameter of the first alignment apertures such that there is slight play there between. Resin is insert molded around the rows of the contacts to form a housing. The contacts are then cut from the carrier strip.
