摘要： A camera shutter equipped with a selftimer device has an interlocking member for coordinating the movement of the camera operating member and the selftimer device to obtain accurate operation of the shutter release member. The interlocking member has a first arm which engages with the operating member during movement thereof at the beginning portion of the shutter release motion and the operating member thereafter drives the interlocking member to a position in which the interlocking member actuates the selftimer device to initiate a timing operation. Near the end of the timing operation, the selftimer device engages with a second arm of the interlocking member and thereafter drives the interlocking member to another position during the course of which a translating lever mounted on the interlocking member actuates the shutter release member to initiate release of the shutter.

摘要： A focal plane shutter for a camera of the type wherein an image is viewed through the photographing lens by use of a viewfinder arranged on top of the camera body. The shutter blade mechanism comprises a group of opening blades and a group of closing blades, each group of blades consisting of a plurality of separate blades which are actuated to run in the vertical direction of the camera for exposing the film. The lower group of blades has a larger vertical dimension when in the retracted condition than the upper group of blades and such is achieved by using a different number or different size of blades in the two blade groups. In both groups, the slit-forming blades are mounted by means of a link mechanism to effect parallel running movement of the blades. The pivot shafts for mounting the slit-forming blades are disposed at a position outside of the region lying vertically below the viewfinder.

摘要： An automatic focusing device for an automatic focusing camera of the double image coincidence focusing type. A coupling mechanism causes an focus detecting movable mirror perform scanning motion according as the stroke of shutter releasing operation. Interlocking with the push-down of the shutter release button, focus detecting motion is performed while the distance from the focal plane to the photographing objective is indicated and/or memorized.During the first half of shutter releasing operation, focus detection and indication and/or memorization of the distance from the focal plane to the photographing objective are performed by the scanning motion of the movable mirror, and during the latter half of the shutter releasing operation, the indication and/or the lense focusing mechanism are controlled by a signal motion corresponding to the memorized value.The memorized value is scanned interlocked with the movement of a timing member released by shutter releasing operation or a focusing member and a lense displacement regulating mechanism is controlled by a signal motion corresponding to the memorized value.

摘要： A camera shutter includes a pair of spaced apart base plates supporting the various shutter components. At least one of the base plates is formed entirely of synthetic resin material which is electrically insulative and which possesses lubricating properties. The synthetic resin base plate has a set of tubular portions extending toward and connected to the other base plate and also has a set of shafts turnably supporting some of the shutter components, such as the control lever and control cam. The synthetic resin base plate also includes a hollow winding frame about which is wound a coil and in which is slidably inserted an armature to form an electromagnet for use in controlling the shutter operation. The use of a synthetic resin base plate dispenses with the necessity of separate lubrication and enables formation of a smaller shutter.

摘要： A camera shutter mechanism for opening and closing a shutter aperture to effect an exposure comprises a group of opening blades movable, when released, from a closed position covering the shutter aperture to an open position uncovering the shutter aperture to thereby initiate an exposure, and a group of closing blades movable, when released, from an open position uncovering the shutter aperture to a closed position covering the shutter aperture to thereby terminate the exposure. A release mechanism releases the opening blades thereby enabling them to move to the open position for initiating the exposure, and subsequently releases the closing blades thereby enabling them to move to the closed position for terminating the exposure. A driving member automatically operates immediately after completion of the exposure to move the group of opening blades back towards the closed position so that the aperture is at least partially covered thereby so as to improve the light-shielding capability of the shutter mechanism.

摘要： A camera shutter mechanism comprises a shutter actuating lever movable between a cocked position and a rest position to actuate a part of the camera shutter mechanism, and a cocking lever having an abutting portion for abutting the actuating lever to move the latter from the rest position thereof into the cocked position thereof. The cocking lever and the actuating lever together include a locking mechanism which releasably locks the actuating lever in the rest position. The locking mechanism and the abutting portion are arranged so that when the actuating lever approaches its rest position, it engages the abutting portion so as to rotate the cocking lever into a position in which the locking mechanism locks the actuating lever.

摘要： A shutter operating mechanism of a camera shutter which has an opening blade and a closing blade operated sequentially to open and close a shutter aperture for an exposure comprises an opening spring normally biasing the opening blade to move from a closed position in which the opening blade covers the shutter aperture to an open position in which the opening blade uncovers the shutter aperture; a second spring normally biasing the closing blade to move from a closed position in which the closing blade covers the shutter aperture to an open position in which the closing blade uncovers the shutter aperture; and a third spring normally biasing the closing blade to move from said open position to said closed position, the arrangement being such that when the shutter is charged, the opening blade and closing blade are in said closed position and when the shutter is released, the closing blade is moved under the bias of said second spring from said closed position to said open position, then the opening blade is moved under the bias of the opening spring from said closed position and to said open position, thereafter the closing blade is returned under the bias of said third spring from said open position to said closed position, thereby completing the exposure. The opening blade may then also be moved to closed position by a fourth spring.Furthermore, there are provided electrical contacts operated by the movement of the closing blade. When the closing blade is moved to uncover the aperture, the contacts are opened or closed and, after the exposure, are closed or opened again by returning movement of the closing blade to the first position.

摘要： In a camera having an aperture and a shutter of the type having opening blades and closing blades operable sequentially to make an exposure, an opening member for actuating the opening blades is releasably coupled to a driving member which is spring biased in a direction to move the opening blades to open position to initiate an exposure. A spring bias is also applied to a closing member for actuating the closing blades in a direction to close the camera aperture and thereby terminate the exposure. As the closing blades approach closed position, the closing member actuates the connecting member so as to release the opening member from the driving member and also engages the opening member so as to move it in a direction to return the opening blades toward set or aperture-closing position. The opening blades are thereby moved at least partially toward closed position as the closing blades complete their closing movement and the transfer of energy from the closing member to the opening member serves to decelerate the closing blades at the end of their movement and thereby reduce impact.
