Abstract: A moving-film display device includes a moving-film having fixed and movable ends, and a stationary body having a counter face that is shaped more distant from the moving-film as a position of the counter face shifts from the fixed end side to the movable end side. A colored portion is disposed at the movable end of the moving-film. An auxiliary electrode is disposed on the moving-film between the fixed end and the movable end. A scanning electrode and holding electrode are disposed on the counter face to face the auxiliary electrode on the fixed end side and movable end side, respectively. A signal line is electrically connected to the holding electrode to supply an image signal. A drive section is configured to control voltages to be supplied to the auxiliary electrode, the scanning electrode, and the holding electrode.

Abstract: A punching machine for the cards or paper bands used in jacquards, dobbies and the like, comprises horizontal punches individually actuated by pusher means through presser rods which may be selectively brought to an ineffective oblique position. Each presser rod is attached to a needle itself attached by its upper end to a vertical rod. All these vertical rods are alternately raised and permitted to return downwardly so as to reciprocate in front of individual electromagnets which are selectively energized to retain some of the said vertical rods at their raised position. The vertical rods are disposed in successive longitudinal rows and the electromagnets are arranged in corresponding superposed horizontal elongated banks, the vertical rods of each row terminating upwardly short of the next bank of electromagnets in order not to interfere with them.
