Abstract: A tape display device comprises a housing supporting a pair of parallel rollers between which a tape is adapted to be wound back and forth to display different visual information contained on the tape. The rollers are driven by a continuous belt via an electric motor. One of the rollers is a tension roller which maintains tension in the tape as it is wound back and forth between the rollers. The tension roller consists of a cylinder having end caps for providing bearing surfaces which bear on respective bushes in the housing to provide rotational mounting of the roller. A drive pinion on the outside of the housing has a stub-axle which extends through the bush and end cap and into the cylinder. A spiral tension spring is attached between the end of the stub-axle and a flange of the end cap.

Abstract: An information board includes display bands having information printed thereon mounted on wind-up rolls, the wind-up rolls being mounted on an axle. A wind-up motor is used to rotate the axle when the motor is rotated in a first direction to wind-up a display band, thereby changing the information shown on the display band. The information board further includes a mechanism which changes the rotational motion of the motor, when rotated in the opposite direction, to axial motion for moving the axle axially. Coupling elements are mounted on the axle to engage a selected wind-up roll when the axle is moved in the axial direction.

Abstract: A poster display apparatus winds a film carrying the posters between spools. The surface speeds of rotation of the spools are equalized by a rising and falling weight carried by a cord interconnecting pulleys carried by the spool axles.

Abstract: An information display system is disclosed having a housing with a viewing window. An elongated flexible sheet is contained within the housing and a plurality of discrete visual messages are provided at longitudinal spaced intervals along the sheet while a controllable motor is mechanically drivenly connected with the sheet to control the position of the sheet. A coded index is also associated with each discrete visual message on the sheet. A microprocessor based central control unit receives input from a user via a keyboard of the desired visual message to be displayed through the housing window. After the user inputs the desired message, the control unit outputs control signals to a motor control module associated with the controllable motor. The motor control module decodes the output signal and then selectively activates the controllable motor in the housing to change the positioning of the sheet until the desired or target visual message is positioned in alignment with the housing viewing window.

Abstract: A device having a housing with two columns of windows and a date window adjacent the top window of one of the columns. A roll of paper is disposed within the housing, with the opposed ends of the paper fixed to separate shafts. The shafts are rotatably connected to the housing and rotation of the shaft moves the midportion of the roll of paper past the windows. An end of each shaft protrudes from the housing to permit manual rotation of the shafts, and the opposed end of one shaft is fitted with an end member. The end member has a conical nose and radially outwardly extending projections. Adjacent to the end member is a clock having a bar attached to the hour shaft for rotation therewith. The bar has a sufficient length to contact the projections of the end member, thereby causing the paper to move from one shaft toward the other.

Abstract: An apparatus and method of storing sheets of film-like material has a substrate which is wound and unwound from two rollers. An exposed portion of the substrate extends between the two rollers. A sheet to be stored is placed on the exposed portion of the substrate. The substrate is then further wound onto one of the rollers and unwound from the other roller. A counter determines the portion of the substrate upon which the sheet is stored by counting the revolutions of a counting roller and accumulating a storage count. To retrieve a stored sheet, the substrate is unwound from the roller upon which it was wound when the sheet was stored until the portion of the substrate upon which the stored sheet was placed is exposed. A counter counts the revolutions of the counting roller and causes the unwinding to cease when the storage count determined when the sheet was stored is reached. A bed is urged upwardly against the rollers to maintain tension on the substrate as it is wound and unwound.

Abstract: A changeable alphanumeric sign with printed characters is disclosed. The sign is universally changeable in the sense that any combination of alphanumeric characters may be displayed by selectively positioning a set of display tapes in each character window. Each set of tapes forms a broken-character display in the respective character window and all character windows are independently controlled to form a broken-word display. This arrangement minimizes the length of display tapes required. An open-loop positioning system is provided whereby all sets of tapes are concurrently but independently positioned to change the characters of the sign.
