摘要： 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. Furthermore, since the returning movement of the main piezoelectric element includes a compulsory force of the auxiliary element as well as a returning force of itself, the returning movement of the main piezoelectric element is insured to be stable as well as speedy, so that very accurate exposure can be obtained.
摘要翻译：本发明涉及一种用于照相机的压电元件驱动型快门装置。快门装置包括主压电元件，其具有能够在关闭位置和打开位置之间移动的自由端，以驱动快门叶片以便打开和关闭;以及辅助压电元件，其具有用于推动快门的自由端当主压电元件的自由端从打开位置返回到关闭位置时，叶片朝向其关闭位置。当主压电元件返回到关闭位置即初始位置时，辅助压电元件有助于主压电元件的返回运动。因此，快门叶片可以以非常高的速度关闭。特别是当需要快门叶片的小孔时，这是非常有效的。此外，由于主压电元件的返回运动包括辅助元件的强制力以及其自身的返回力，所以主压电元件的返回运动保证稳定且快速，从而非常准确可以获得暴露。

摘要： 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. For operation of the shutter, a negative voltage is first applied across the piezo-electric element to set the same to its fixed home position, and then a positive voltage is applied to move the shutter from the home position to a predetermined opening position, whereafter the negative voltage is applied again to return the shutter to its initial position rapidly. The position of the shutter is also checked to assure proper operation of the camera.

摘要： 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.

摘要： A film feeding apparatus of a camera using a film having two perforations in each frame. A perforation detecting lever has claws spaced at a predetermined distance apart from each other so that the distance therebetween is equal to the distance between the two perforations which are adjacent to each other across the boundary between frames. The perforation detecting lever engages the perforations and disengages therefrom in unison with an operation for feeding one frame to be performed after the proceeding frame is exposed to light. As a result, film feeding is allowed to proceed until both claws simultaneously engage two respective perforations in the film which occurs after the film has advanced one frame.
