Abstract: A method for determining a charge/voltage conversion ratio of a solid state image pickup element with an electronic shutter function which is capable of transferring signal charge accumulated in a photosensitive portion to a substrate. A voltage of a predetermined first level is applied to the substrate to measure an output voltage at an output portion, and then a voltage of a second level higher than that of the first level is applied to the substrate to measure a current flowing through the substrate, thereby obtaining a charge/voltage conversion ratio in accordance with a ratio between the measured output voltage and the measured current.

Abstract: An intermittently operating driving mechanism for a record medium selecting apparatus of a player wherein two principal components thereof do not operate at a time but operate independently of each other to assure a high space factor and the interval of time over which each of them do not operate can be set freely. A tray base plate selectively receives, at an outwardly projected position, tape cassettes on cassette receiving members thereon and moves to a home position, at which one of the cassettes is selected. The selected cassette is transported by a tray driving plate to a playing position at which the cassette is played. Each of the tray base plate and the tray driving plate has a toothed portion, with which a gear of a cam plate is selectively engaged to move the tray base plate or the tray driving plate between the respective end positions of movement.

Abstract: A method for performing a reproduction and search operation on a data recording and reproducing device of the helical scan type which includes a pair of recording and reproducing heads mounted on a rotary drum. The method includes the steps of: (a) during the reproduction operation, transporting the tape and rotating the rotary drum such that a relative speed between said tape and the heads is either a first relative speed or a second relative speed which is less than the first relative speed; and (b) during the search operation, transporting the tape at a speed substantially greater than a tape speed used during the reproduction operation and rotating the rotary drum at a speed such that a relative speed between the tape and the heads is equal to the second lower relative speed.

Abstract: An apparatus for recording and reproducing digital signals using a helical scan in which a drum of reduced diameter is employed without changing the tape format. Two heads are mounted on a drum at the same height in opposition to each other with a product of the diameter D of the drum and the wrap-around angle of the tape with respect to the rotary drum being constant while the speed of the drum is increased to a speed N times higher than a predetermined speed. One of the heads is mounted higher than the other by a distance of (1-1/N)P to provide a step, and the other head being is mounted at a position an angle behind the position at which the other head directly opposes the one of the heads, which angle is defined by: ##EQU1## where L is the track length in the tape format used when the rotary drum rotates at the predetermined rotational speed, .THETA. is the track angle, P is the track pitch, and C is a constant dependent on the drum diameter D and the wrap-around angle.

Abstract: A solid state image pick-up device includes means for cancelling a difference in impedance between photo-sensing areas in a photo-sensitive array. The impedance difference cancelling means cancels or makes the difference of impedance at each photo-sensing area ignorable to unify the charge handling in respective photo-sensing areas. In practice, the impedance difference cancelling means provides a resistance high enough to make the impedance difference between respective photo-sensing areas ignorable.
