摘要： PURPOSE:To remove the slack of a tape by exerting a movement force toward a direction away from a tape extraction face on a tape reel even without using a special member. CONSTITUTION:Two tape reels in which both ends of a tape have been fixed and bonded are housed inside a cassette case in such a way that the lower end part of their hub is situated in a state having a slight margin inside a reel-stand insertion hole formed in the bottom wall of a cassette case. A part between the two tape reels of the tape is guided to the outside of the cassette case and positioned along a tape extraction face. The tip part of a reel pressure spring 20 whose mounting end part 20a is fixed to the cassette case 2, whose tip part 20b comes into elastic contact with a spring stop part 15c installed in the central part of the top part of the tape reel 13 and which presses the tape reel nearly toward the lower part is tilted in such a way that the direction P of the horizontal component force of a force by means of which said tip part presses the tape reel becomes a direction opposite to that of the tape extraction face 5.

摘要： PURPOSE:To prevent force in the direction of separating them from adding to upper and lower halves forming a cassette case even when excess force so as to make this lid move to the position of opening is applied to a front lid locked in the position of clogging to clog the front face of a magnetic tape. CONSTITUTION:The fulcrum pin 24 of the upper end part of a lid locking member 23 provided projectingly with an engaged projecting part 25 engaging with an engaging part 16 formed to the inside face of the front lid 9 energized repulsively by rotational force in the direction of moving the lower end forth is supported freely rotatably between both the upper and lower halves 3, 4 and simultaneously a stopper part 19 abutting or approaching to the upper face of the relevant engaged projecting part in a locked state where the above- mentioned engaged projecting part is engaged with the engaging part of the lid is formed to the lower half. Since the force applied to the front lid so as to rotate this lid in the direction of opening is received by the stopper part of the lower half through the engaging part and the engaged projecting part of the lid locking member, the above-mentioned force is unapplied so as to separate the upper and lower halves.

摘要： PURPOSE:To make a tape cassette campatible with a conventional tape cassette by making the inner lid of a tape cassette with an inner lid attached to the front lid to be openable with an opening lid member of a tape cassette without the inner lid. CONSTITUTION:When loading to a cassette loading part, a front lid 9 is opened to stick upwards by an opening lid part, and near the end of the opening operation, it is further opened by being pushed up with a projecting surface part 30, the inner lid moves above a magnetic tape T, an opening part 8 is completely opened, and the tape loading is executed. Then, an opening lid member with the same height as the opening lid part which opens the front lid 9 of a commonly used tape cassette without the inner lid 10 can be used. Thus, it becomes compatible with the conventional tape cassette.

摘要： PURPOSE:To improve the exactness of reel lock by twisting a link part by pressing one lock part, turning a lock part, moving the other lock part and rotating another tape reel in a direction increasing the tension of a tape. CONSTITUTION:A lock pawl 19a is moved in an arrow E direction by force F applied onto a lock arm 19, and a lock part 13 is turned in a counter-closwise direction by the torsion of a link part 14. With this turn, another lock arm 19' receives turning force in the counter-clockwise direction and therefore, a lock pawl 19'a is pressed to a gear 8' of a lower flange 7' on a T reel side. Then, a lower flange 7 further receives rotational force in an arrow B' direction. In such a way, since force in the direction increasing the tape tension is applied onto a magnetic tape 5 can be prevented from being unfastened. Thus, the suitable tension is applied onto the tape at all times and the reel lock is enabled without fail.

摘要： PURPOSE:To always set excellent exposure even in either case of outdoor or indoor by detecting the change of color temperature around an object (the change of photographing conditions) and changing a photometric condition for deciding exposure based on it. CONSTITUTION:In an electronic camera where the image light of the object is converted to an electric image pickup signal by an image pickup means, a system controller 1 controls both of an image pickup part 10 and a recording part 20. The image pickup part 10 has a white balance detection circuit 14 and detects the color temperature around the object based on the respective color components of the image pickup output of an image pickup element 12. The system controller 1 judges that the photographing is executed outdoors when the detected color temperature is >=400 deg.K and judges that it is executed indoors when the color temperature is

摘要： PURPOSE:To always set a satisfactory photometric area by varying a photometric area for determining exposure in response to a change in a lens focal length. CONSTITUTION:When an operator operates the zoom switch of an operating part 4 to select a photographing view angle, a zoom motor 15 drives a lens 2a to vary a view angle and output a desired view angle. Here, a zoom position detecting circuit 14 detects which range the zoom position lies in. Then a system controller 1 judges the detection signal of the zoom position detecting circuit 14 to determine a photometric range in a metering circuit 13. Consequently, in the case of tele photographing, the photometric range (s) is within a zoomed-up face of a figure. In the case of wide photographing, the photometric range (s) becomes small enough to meter only a figure in the central part. Thus, an optimum photometric area is automatically set in the case of tele or wide photographing.

摘要： PURPOSE:To stop a system to be driven quickly and highly accurately to a stop position by reciprocating the rotor of a step motor and vibrating the entire system to be driven. CONSTITUTION:A step motor 1 is coupled directly with a lead screw 2, and a pin 4 arranged on a linear arm 3 is engaged in the groove of the lead screw 2. Rotation of the step motor 1 causes rotation of the lead screw 2 thus moving the pin 4 and the linear arm 3 in the direction of an arrow LR. When the step motor 1 is stopped, two adjoining phases are excited with the vibration frequency of the system to be driven then they are excited with high region frequency to which the system does not respond.

摘要： PURPOSE:To rotate feeding and winding tape reels with respective required torque by changing the torque of rotation of a driven rotary member in case of the rotation in the 1st direction and the 2nd direction respectively. CONSTITUTION:The torque of rotation of the winding tape reel set up on a winding reel turn table is based upon the torque obtained by transmitting torque from a driving gear 23 to a driven gear 31 through felts 28, 37 and set up so as to be proper value required for the rotation of the winding tape reel. The torque of rotation of a feeding tape reel set up on a feeding reel turn table is based upon the torque obtained by transmitting the torque of the driving gear 23 to the driven gear 31 through felts 36, 37 and set up to a value larger than the torque of rotation of the winding tape reel so as to be a proper value required for the rotation of the feeding tape reel.
