Abstract: A photographic camera having in a patrone chamber for loading a film patrone a rotational drive mechanism for rotating a film in a direction for loosening at least the film peripheral relative to an axis along a patrone axis and extending toward a leading edge of the film and a film insertion mechanism for inserting the leading edge of the film into a film outlet opening extending from the patrone chamber to a film exposure section with the rotation of the film. With this construction, when the film patrone is accommodated in the patrone chamber, wherever the leading edge of the film may be placed about the patrone axis, the film insertion mechanism rotates the film about the axis along the patrone axis thereby to guide the leading edge of the film to be inserted into the film outlet opening extending to a manually-operated film winding-up mechanism or to an automatic film winding-up device.

Abstract: A photographic camera of the type including a piezo-electric actuating element driven by energy accumulated in a capacitor for actuating a shutter wherein the piezo-electric element operates in stability to assure accurate appropriate opening and closing operation of the shutter of the camera and the capacitor is charged up rapidly to allow subsequent photographing operation to be done in a minute. In the camera, a charged voltage of the capacitor is checked several times to determine if it is sufficient to assure proper operation of the piezo-electric element, and if a then required level is not reached, then the capacitor is charged to the required voltage. While the capacitor is being charged, charging of a capacitor for a flash is inhibited.

Abstract: The disclosure relates a piezoelectric element-drive type shutter apparatus for camera. The shutter apparatus includes a main piezoelectric element having a free end which is able to move between a closed position and an opening position to drive shutter blades so as to be opened and closed, and an auxiliary piezoelectric element having a free end for urging the shutter blades toward its closed position when the free end of the main piezoelectric element returns from the opening position to the closed position. When the main piezoelectric element returns to the closed position, i.e. an initial position, the auxiliary piezoelectric element assists the returning movement of the main piezoelectric element. Accordingly, the shutter blades can be closed at a very high speed. This is very effective particularly when a small aperture of the shutter blade is desired.

Abstract: There is disclosed a light-sensitive device comprising: at least one light-sensitive element having a surface for receiving an incident light, and at least one color filter made from polyimide resin mixed with an organic pigment, applied on the light-receiving surface of the light-sensitive element. There is also disclosed a manufacturing method of a light-sensitive device having one or more light-sensitive regions, comprising the steps of:(a) applying at least one color filter layer on the light-receiving surface of a light-sensitive region formed on a wafer of a semiconductor material, said layer being made from a polyimide resin containing an organic pigment;(b) dicing said wafer into individual chips;(c) bonding one of said chips to a lead frame member having electrical lead means;(d) bonding electrical wires between the chip and said electrical lead means of said lead frame member for the connection to at least one external device; and(e) molding said chip bonded to said lead frame members with a resin.

Abstract: A shutter actuating device of the type employing a piezoelectric element as an actuating element which attains stabilization of the shutter opening speed of a shutter device. The device includes a piezoelectric element charging circuit which charges a piezoelectric element with constant current so that the rising speed of the charged voltage of the piezoelectric element may be maintained constant. Means is also disclosed for minimizing a time lag until a minimum aperture for exposure is reached after triggering of a shutter release operation. Higher constant charging current is supplied to the piezoelectric element until a time just before the minimum aperture for exposure is presented, and after then the piezoelectric element is charged with lower constant current.
