The present invention is a picture print controlling device. Complex image signals which are input to the device are stored in memory and a picture is displayed on a monitor and/or is printed on a photographic paper. The addresses of a printed picture corresponding to a predetermined area of the monitor screen are separated from the remaining addresses of the screen and stored in designated addresses so that just the picture of the predetermined area can be printed and the remainder of the picture may not printed. If printed, data of the designated addresses are sequentially read to be printed. Furthermore, a user can choose the size and location of the predetermined area of the selected cut partial picture. In addition, the device of this invention may be applied to a picture print device such as a color video printer.

A clothes washing machine includes an outer tank, a plurality of vertical suspenders hung by their upper ends adjacent respective corners of the tank, and a water container disposed within the tank and supported at lower ends of the suspenders. The upper ends of the suspenders are secured to a cover member which is attached to an upper end of the tank. The upper end of each suspender projects through a rib-reinforced hole formed in the cover and is secured to the cover by a cap-pin fastener device. A unit constituted by the cover, suspenders, and water container can be tested prior to being installed in the tank.

Disclosed is an automatic contrast correction method and apparatus for optimizing contrast of a picture screen. There is included an effective picture screen extractor for extracting video data corresponding to the effective picture screen among video data in the picture screen, a plurality of amplifiers for receiving the video data and amplifying the received video data for output, and a microcomputer for comparing the average value which is calculated from the video data of the effective picture screen with a previously set reference value and regulating an amplification factor by supplying a control signal to the amplifiers according to the comparison result. Even if video images photographed toward the sun are printed, it can be prevented from being printed in a dark state, thereby obtaining a good quality of picture.
