    Abstract: PROBLEM TO BE SOLVED: To eliminate the restrictions of the quantity of rotation on the base of a turntable and securely transmit signal data to a signal ource by supplying electric power from the base to the turntable side in a noncontact manner and sending and receiving signal data as light signal data between the base and turntable in a noncontact manner. SOLUTION: The turntable is equipped with, for example, a video camera M and the turntable 12 rotates on the base 10, so that the device is used as, for example, a video monitor device for security. A noncontact power supply part 14 is provided opposite the base 10 and turntable 12 and supplies electric power to the 2nd processing circuit 44 of a noncontact signal transmission processing means 16 and the video camera M on the side of the turntable 12 without contacting. The noncontact signal transmission processing means 16 sends and receives the signal data of the video camera M as a signal source between the base 10 and turntable 12 as the light signal data through the hollow part 20a of a shaft 20 in a noncontact manner.

    Abstract: PURPOSE:To attain miniaturization, to reduce an axial loss and to improve reliability by providing a magnetic circuit cancelling magnetic attracting force between a rotor and a stator. CONSTITUTION:Coreless structure capable of cancelling or eliminating the magnetic attracting force between the rotor R and the stator S, in such a manner that a back yoke 6 is supported with respect to the flange part 4a of a plastic magnet 4 is adopted. Therefore, the load of force by the magnetic attracting force is not applied to a bearing 10, so that the bearing 10 can be miniaturized and an actuator can be made thinner in its axial direction. Further, a power feeding part 62 for taking out the driving force of each actuator can take out the driving force of each actuator, in its radial direction. A system for taking out the driving force is applied to a gimbal mechanism, to increase the degree of freedom of the design of the gimbal mechanism.

    Abstract: PURPOSE:To suppress the wear of a reel base, to prevent stick slip and to stabilize tape traveling by forming a string in a tape tension adjusting mechanism with belt-like material and bringing the string into contact with a reel base slidably and planely. CONSTITUTION:The string 4 is formed in the belt-like shape of prescribed width by plate work in a tape tension adjusting mechanism 1 which is constituted so that the string 4 is pressed to the guiding groove of the reel base 2 and the tension of a magnetic tape T is held constant. Thus, the string 4 is slidably and planely brought into contact with the reel base 2 formed of synthetic resin, and the wear of the reel base 2 is decreased, and simultaneously, the coefficient of friction is increased, then the change of braking force preventing the stick slip is suppressed. Consequently, the traveling of the tape is stabilized for a long time.

    Abstract: PURPOSE:To reduce the number of parts and manpower of the assembly by integrating a reel claw for engaging a reel to be wound with a magnetic tape with a reel base. CONSTITUTION:An arm piece 12 is deformably erected on the reel base 11 in the radial direction at a required space from a bearing cylinder 11a, and the reel claw 13 is projectively provided outwardly on the tip of this arm piece 12. When an engagement claw part 9 of the reel 7 runs on this reel claw 13, the reel claw 13 is pressed and the arm piece 12 is inclined and deformed to escape from the engagement claw part 9, thus preventing the reel 7 from floating to the reel base 11.

    Abstract: PURPOSE:To correct a hand blur simply and surely by reducing an image of an object formed on an image pickup face based on the result of detection by a hand blur detection means segmenting an outputting a picked-up picture on the image pickup face. CONSTITUTION:A signal processing circuit 8 converts an image pickup signal outputted from an image pickup element 2 into a video signal and stores it into a memory circuit 10. A hand blur detection circuit 11 receives a video signal outputted from the circuit 8 to detect the quantity of hand blur. A zoom lens drive circuit 12 on the occurrence of hand blur mooves a zoom lens group 4B toward the wide position in response to the quantity of hand blur. Thus, an image of an object formed on the image pickup face of the image pickup element 2 is reduced by the quantity corresponding to the hand blur. A memory control circuit 14 based on the result of detection of hand blur selects an address data of the memory circuit 10 and outputs the result. Thus, the hand blur is corrected from the video signal outputted from the circuit 10 based on the result of detection of the hand blur and then the hand blur is simply and surely corrected in this way.

    Abstract: PURPOSE:To reduce the load exerted on a tape at the tape rewinding time and to reduce the electric power consumption of a reel motor, etc. by rotating a rotary drum in the reverse direction to recording and reproducing times with winding the tape on the rotary drum. CONSTITUTION:When a rewinding switch 1 is pushed, a drum motor 4 is reversed by switching the driving circuit 3 of a rotary drum by the controller 2 of a microcomputer, etc. The rewinding travel of the tape is started at about the same time or just before the start of the reversal of the drum motor 4. The rotary drum is reversed at about several times or 30 times speed compared to recording and reproducing times. The load exerted on the tape is thus reduced drastically, the tape damage accompanied by the tape traveling is also reduced and the electric power consumption of a reel motor, etc. for driving the tape traveling is reduced as well.
