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 piezoelectric 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： 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 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 camera operated by a remote control device includes a zoom lens. The camera has a plurality of photographing modes. In a first mode, an object is photographed at a predetermined magnification and in a second mode, the object is photographed together with the background thereof. A desired photographing can be taken in response to a signal from the remote control device.Furthermore, the camera can rotate to upward, downward, rightward and leftward by a signal from the remote control device.

摘要： A camera system on which a remote control device enables photographing with a camera body directed to a user of the remote control device, is controlled by a program of a microcomputer for controlling provided in the camera body. In this program, while the lens direction of the camera body is being shifted by the remote control device, a release signal sent from the remote control device is disregarded. As a result, even if the user pushes a release button by mistake to transmit a release signal, the microcomputer does not accept a remote control release signal while the lens is moving by a remote control drive signal, thereby preventing exposure.
