摘要： PURPOSE:To optimize the detection area of an illuminating type range-finding represented by an optical intervehicular distance meter. CONSTITUTION:The optical intervehicular distance meter is mounted in a running vehicle body and includes a pair of projection means 1 and reception means 2. The projection means 1 projects within a predetermined illuminating angle range a primary beam 5 including center luminous flux 3 and marginal luminous flux 4 toward a target vehicle body located in a predetermined range. The reception means 2 receives a secondary beam 10 reflected from the target object and measures the time required for the secondary beam to return, thereby measuring the intervehicular distance. The projection means 1 is provided with a liquid crystal filter 15 whereby the intensity of the marginal luminous flux 4 is variably lowered. Thereby, in a long range, the marginal luminous flux 4 is made ineffective while the center luminous flux 3 is kept effective so as to narrow an effective illuminating angle range. On the other hand, in a short range, the marginal luminous flux 4 is held effective to widen an effective illuminating angle range CA. Further, a control circuit 17 which adjusts the intensity of the marginal luminous flux 4 by controlling the liquid crystal filter 15, is provided so that the effective illuminating angle range can be set to the optimum.

摘要： PURPOSE:To enable fast consecutive photography by moving a mirror lock member away from a mirror lock position with a release operation end signal. CONSTITUTION:A mirror lock lever 405 is unable to swing counterclockwise because its leftward extending arm 405b is stopped by the pin 201b of the shaft part 201a of a release button 201, and an arm 401b and the arm 405a are isolated, so that a spring 406 enters a tensed state. Releasing operation is therefore performed in this state, and then the pin 201b of the release button 201 moves down, so the mirror lock lever 405 is allowed to swing counterclockwise through the operation of the tensed spring 406, thereby stopping a stopper pin 407 where it abuts on the arm 401b. A lock claw 405c locks a mirror holding frame 14a at this position. Consequently, a mirror 14 which has rocked to its elevation position is locked to inhibit the mirror from moving throughout the photography in fast consecutive photographic mode, thereby performing the fast photography.

摘要： PURPOSE:To enable a winding action by making a one-cycle action such that an open blade is carried from the second position to the first position and a closed blade vice versa both resisting respective restoring force and thereafter said blades are returned to respective initial positions through an intermediate position. CONSTITUTION:The blade-action controlling device for focal plane shutter is positioned movably between the first position to close an aperture and the second position to open the aperture. The one cycle is made such that the open blade is carried from its initial position where it is made movable from the first position to the second one while the closed blade is carried from its initial position where it is made movable from the second position to the first one through respective intermediate position where the open blade is made movable from the second position to the first one while the closed blade is from the first position to the second one, and further to respective initial positions. An open-blade driving lever 1 and a closed-blade driving lever 4 are attracted by respective electric magnets 18 when they come to a set-completing position being driven by a motor M. Consequently, the levers respectively move to and held at the first position to close the aperture, then move to and held at the second position to open the aperture. In such a way, the winking action is executed.

摘要： PURPOSE:To provide a motor, in which rotary balance can be kept for a prolonged term by inhibiting the generation of backlash in a device and which can be used for the prolonged term as compared to conventional devices by enabling second adjustment when rotary balance is lost. CONSTITUTION:The diameter of the revolution of a magnet yoke 13 is formed in size larger than a part of the outside diameter of a stator section, and a balance adjusting member 16 is mounted inside the magnet yoke 13. Since the balance adjusting member 16 is installed, the backlash of the member due to the vibrations of a motor is eliminated, thus employing the device for a prolonged term. The balance adjusting member 16 can be exchanged and mounted and dismantled without disassembling the device, thus easily adjusting balance again.

摘要： PURPOSE:To miniaturize the device by using a picture reproduction means to control a period for picture reproduction based on picture data read from a storage means to adjust the exposure thereby eliminating the need for a mechanical shutter. CONSTITUTION:Pixel data PD outputted from a frame memory 15 are converted into an analog pixel signal by a D/A converter 19 and fed to a video output signal processing section 20, converted into a picture signal and displayed on a CRT 21 as a reproduced picture. When an exposure time is longer than one frame period, a counter 24 counts down by one synchronously with a succeeding vertical synchronizing signal SV and a central control section 27 restarts an address counter 16. Then the same operation is repeated till the counter 24 stops down-count synchronously with the vertical synchronizing signal SV. As a result, a same still picture is continuously exposed on a silver salt film 23 based on the pixel data stored in the memory 15.
