摘要： PURPOSE:To eliminate the unevenness of exposure by providing an actuating member which couples and actuates a shutter blade and whose actuating area is regulated by a shutter substrate, a locking member which locks a driving member against pressing force and a spring which presses the actuating member in the direction where it approaches to the driving member. CONSTITUTION:When a locking pawl 2 is separated from the driving member 4, the member 4 is turned by a driving spring 5 and abuts on the locking member 6, then it turns the member 6 in the same direction. Therefore, the member 4 turns a closing arm through the member 6 so as to actuate the shutter blade group. When the locking pawl 2 locks the member 4 by resisting the spring 5, the member 4 stands by a position distant from the member 6 and the member 6 is stretched by a tension spring 8 through a blade actuating member 3, so that the circumference part 6b of the member 6 is allowed to abut on a circular arc-shaped hole 1c and the actuating area is regulated. Thus, exposing accuracy is improved and the unevenness of exposure is prevented from occurring.

摘要： PURPOSE:To reduce the cost by forming a fitting surface for the other lens which is based upon the curvature of one lens on a frame body where one lens is formed integrally. CONSTITUTION:One lens 31 is formed on the frame body 25, the fitting surface for the other lens which is based upon the curvature of one lens 31 is formed on the frame body 25, and a frame body operation part 28 or operation guide part 34 is formed integrally with the frame body 25 where one lens 31 is formed integrally. Consequently, components of a camera is decreased in number and assembly man-hours and inspection man-hours are decreased correspondingly, so the cost of the lens support structure is reducible and the lens 31 and frame body 25 are united to eliminate play, thereby obtaining the high-reliability lens support structure.

摘要： PURPOSE:To permit automatic opening and closing of barriers without providing a motor to be exclusively used for opening and closing the barriers and to reduce the size and cost of the titled shutter by executing the opening and closing operations of the barriers covering the front face of a lens by means of the same motor before and after the actuation of a shutter. CONSTITUTION:Detention of a ratchet wheel 7 by a detaining lever 8 is released and a driving ring 1 and a distance ring 4 are turned right by the forward run of a step motor 2 when an electromagnet 9 is energized as a user operates a release button. The electromagnet 9 is demagnetized and the ring 4 is detained so that a photographing lens is positioned to the focal position when the ring comes to the set focal point. The barriers 12, 13 which are held closed are opened by the gear connection of an interlock gear 10 and a tooth-laced gear 11 when the driving ring 1 in the lens actuation range is turned right. The step motor 2 runs backward when a preset aperture quantity is attained. The ring 1 is then turned left to end the exposing action. The barriers 12, 13 return to the original positions.

摘要： PURPOSE: To enable selecting modes by a single board, by a method wherein branching parts facing to the respective lands are arranged in input lands and output lands which are connected with an external equipment, the respective lands with which electric elements are not connected initially but connected by selecting lands at the time of mode determination. CONSTITUTION: Lands 42a, 42b, 42c facing the branching parts of an output land are connected with lands 42a, 42b, 42c facing the branching parts of a first input land 43 and lands 44a, 44b facing the branching parts of an input signal land 44 for selecting the kinds of indications. According to distance measurement results, the binary number of pulses is serially outputted to the land 42a. The distance measurement results expressed in cm unit and mm unit are outputted to the lands 42b, 42. The lands 43a, 43b, 43c can designate the division points of distance, and select a short distance zone, a middle distance zone and a lsnf distance zone, respectively. The land 44a turns the display LED of an external equipment on, when the distance measurement results are obtained. The land 44b turns the LED on when the distance measurement results are not obtained.

摘要： PURPOSE: To operate a human body detector at all times without resting on an external power source by making up it with a generating set producing electric power with a water flow, a condensing set storing the generated electricity and a body detecting sensor detecting the presence of a user. CONSTITUTION: In order to store water in a water storage tank 2 again after flushing a toilet bowl, water is fed to the tank from a feed water pipe 2b. Then the water fed to an upper cover 2a of the tank 2 flows down toward an inner part of the tank 2 from a hole part 2c. Next, a water turbine 6a is rotated by dint of the fallen water and this rotation is transmitted to a first pulley 6b via a second pulley and a belt 6m, thereby rotating the turning shaft of a generator 6f. Thus this generator 6f operates for generation. In succession, electric power generated is stored in a condensing set 8 connected to this generator 6f. This condensing set 8 serves as a power source for a body detecting sensor 4, supplying electricity to this sensor 4. With this constitution, since a generating set is operated by way of utilizing the power of flushing water, electric charges are thus savable.

摘要： PURPOSE:To miniaturize a position detection device and enhance its precision by providing electrodes, one of which decreases its electrostatic capacity and the other increases it according to movement of a slider and converting differ ence between their electrostatic capacities into time delay by an integration circuit to make it a positional detection signal. CONSTITUTION:A bottom case 1 is grounded through a metal terminal 1b. A top case 2 is fixed to the bottom case 1, so that a slider 4 arranged movably in single direction on a groove 1a of the bottom case 1, is sandwiched between them. On a board 3, electrodes Ea and Eb are allocated, and according to the movement of the slider 4, the width of one electrode increases and that of the other electrode decreases at all times, thus, electrostatic capacity decreases and increases. The slider 4 consists of a knob 4a and a contact chip 4b, and the contact chip 4b is pressed and brought into contact with a side wall 1c for electrical conduction, and it can move while keeping a specified interval from the electrodes Ea and Eb.

摘要： PURPOSE:To instantaneously cut off supply of fluid in the case of a power failure or the like by interposing, between a drive member for moving a valve body and a drive source, a switch member capable of moving between a drive force transmitting position and a drive force cutting off position so as to operate the switch member at the time of power failure. CONSTITUTION:When a coil 28 is energized and an iron core 27 is excited, an attracting piece 21 is attracted and held. When a motor 23 is rotated forward, a slider 12 is moved right via a gear train. Although a pin 12e of the slider 12 is separated from an arm 16a of a lever 16, the lever 16 is located in a drive force transmitting position since the attracting piece 21 is attracted and held. When the slider 12 is further moved, a valve body 5 is pressed via a shaft 7, to be thus opened. In this state, the iron core 27 is de-excited to release the attracting piece 21 if energization to a device is cut off due to a power failure or the like. Consequently, the lever 16 is turned to a power untransmissible position by a spring 18 so that the valve body 5 is instantaneously closed by a closing spring 13.

摘要： PURPOSE:To take advantage of characteristics of two shutters according to an aim of photographing by selectively operating the lens shutter LS or a focal plane shutter FPS by one switching means and automatically setting the FPS even to a dark object exceeding the hand-shaking limit of the LS. CONSTITUTION:An image of an object is limited on an photographing plane 4 through a photographing lens 2 fitted to a camera main body 1, and formed on a photosensitive material F. The LS8 is provided behind the lens 2, and its opening is controlled by a 1st driving means D1 in an electronic circuit 10. The FPS11 provided on the base 12 of the main body 1 controls exposure time at a prescribed time interval by a 2nd driving means D2. The driving system calculating means 105 of the main body 1 inputs the focal length and film sensitivity of a metering circuit 101 inputting the brightness of the object and those of the lens of a range finding circuit 102 inputting a distance up to the object through means 104 and 20. According to an output from the means 105, a sequence control means SC switches and controls the driving means D1 and D2.
