摘要:
A liquid crystal display unit is described, which includes a first substrate, a second substrate opposing to the first substrate, pixel driving elements, first and second insulation layers, a planarizing film and a liquid crystal layer. The pixel driving elements are disposed on the first substrate and between the first and second substrates. The first insulation layer is deposited over the first substrate and the pixel driving elements. The planarizing film is formed on the first insulation layer. This planarizing film provides a substantially flat surface over the first substrate to minimize a height of a step present between an area corresponding to each pixel driving element and an area locating adjacent to the pixel driving element on the first substrate. The second insulation layer is formed on the planarizing film. The display electrodes are formed on the second insulation layer and electrically connected to the pixel driving elements, respectively. The liquid crystal layer is located between the first substrate and said second substrate.

A first reproduction signal is reproduced by use of a first pair of magnetic heads having first and second azimuth angles and arranged around a rotary drum at two opposing angular positions 180 degrees away from each other, respectively. A second reproduction signal is reproduced by use of a second pair of magnetic heads having first and second azimuth angles and arranged around the rotary drum at two opposing angular positions 180 degrees away from each other, respectively. A video signal is reproduced based on the first and second reproduction signals. The magnetic tape travel speed is set to a value (2n+1.+-.m/M) times higher than that in recording, where n is an integer of 0 or more; m and M are a natural number, respectively; T.gtoreq.12/(P+Q) (T: an integer) when m/M=2k/T; and P>0, Q>0.

An image formation apparatus such as a color copier or color printer comprises a plurality of development units, a development bias power source to supply power sources to the development units, a switch for allowing the output power of the development bias power source to be supplied to the development unit selected in accordance with a sequence control signal for image formation generated from a sequence controller, and a power supply control circuit to selectively to supply the output power of the development bias power source to the development unit which is developing only for a development period of time of each development unit. The development units are fixedly arranged near the photosensitive drum on which an electrostatic latent image is formed. The development bias power source includes both an AC component and a DC component. Since the amplitude, frequency, DC potential, and the like of the development bias power source are switched for each development unit selected, it is sufficient to use only one expensive power source. In this manner, image deterioration by the mechanical vibration due to the movement of the development unit can be eliminated.
