    Abstract: A signal address system is adapted for use with apparatus for magnetically recording and reproducing a signal on a rotary member. At least one magnetic head is provided for recording and reproducing a video signal on a rotating magnetic member. The head is moved by drive pulses associated with field signals or frame signals of the video signal. Thus, the number of drive pulses may be used to provide an output signal representing the total number of drive pulses, which is substantially equivalent to an address signal. Thus, an address may be called out without requiring the recording and reproduction of a specific address signal on the magnetic medium.

    Abstract: An erasing system for a magnetic recording and reproducing apparatus using a rotary magnetic medium in which same magnetic head is used both for erasing and recording. The erasing action is started from a point when a stepping of the magnetic head has been substantially ended in a vertical blanking interval of a video signal and continued to a point of an end of an interval in unit of one field from a start of the stepping.

    Abstract: A recording and reproducing time indicator in a magnetic recording and reproducing apparatus which makes magnetic recording and reproduction by linear movement of magnetic heads in contact with a rotary magnetic medium. The indicator comprises a time indication part having a scale showing the position of magnetic heads into time, a pointer for indicating a scale on said time indication part, and a pointer driving means for moving said pointer in response to the position of magnetic heads moved by the head moving means.

    Abstract: A variable resistor comprises a rotatable screw shaft having a screw on the outer periphery thereof, a resistor disposed in parallel with the screw shaft, a movable member formed of a bent leaf spring of electroconductive metal, and a movable member holder through which the screw shaft passes. The movable member holder holds the movable member. The movable member has at one end thereof a slidable contact portion contacting with the resistor. The other end of the movable member contacts with the portions of the grooves of the screw having the effective screw diameter. The movable member also has a protuberant middle portion contacting with adjacent crests of the screw. The edge line of the other end of the movable member has an inclination angle with respect to a vertical plane to the axis of the screw shaft, which angle is reverse in direction to the lead angle of the screw and substantially equal to the lead angle in absolute value.

    Abstract: A tape cartridge loading device for loading and removing a tape cartridge in and from a chassis of a cartridge type recording and reproducing apparatus. Upon complete insertion of the cartridge into the chassis, a reel shaft is moved upwardly and fits into the cartridge. Upon withdrawal of the reel shaft from the cartridge, the cartridge is released from a locked position where it is ready for removal from the chassis.

    Abstract: An automatic gain control circuit is disclosed, the circuit being capable of varying an input voltage of a circuit amplifying an AGC voltage by means of a variable resistor, which voltage is to be fed to a high frequency stage of a television receiver. Accordingly, the location of a rising point where the AGC voltage makes a distinct increase on an input-signal intensity AGC voltage characteristic is likewise varied.
