    • Methods and assemblies are described for displaying interchangeable graphics sheets on a display face of a merchandise cabinet such as a vending machine. The interchangeable sheets are stored on spool assemblies disposed within the cabinet and may be either manually or automatically manipulated in order to selectively register different graphics sheets within the display face of the vending machine. In a first embodiment, the graphics sheets have adhesive areas thereon in order to attach an old graphic sheet to a new graphic sheet to unwind the new graphic sheet from the spool assembly and position it into the display field on the face of the vending machine. The old graphics sheet functions as a leader for the new graphics sheet. In a second embodiment, the graphics sheets are provided with tear-off flexible leaders which are utilized to unwind the sheets from the storage spool assemblies and to position the graphics sheet into registry with the display fields on the face of the vending machine. In a third embodiment, an elongated graphics sheet having groups of graphic regions spaced thereon is wound onto a pair of spaced spool assemblies on opposite sides of the display field. A drive mechanism for rotating the spools is provided to selectively position selected ones of the groups of graphics into registry with the display field. A controller for selectively activating the drive mechanism to position the selected groups of graphics in the display field is provided and may include a timer for automatically activating the drive mechanism to change the groups of graphics or a suitable remote control and detector combination in order to selectively change the graphics by remote command signals.
    • 描述了用于在诸如自动售货机的商品橱柜的显示面上显示可互换的图形纸的方法和组件。 可互换的纸张存储在设置在机柜内的卷轴组件上,并且可以手动地或自动地操纵,以便在售货机的显示面内选择性地注册不同的图形纸。 在第一实施例中,图形片材在其上具有粘合区域,以便将旧的图形片材附接到新的图形片材,以从卷轴组件展开新的图形片材并将其定位到自动售货机的表面上的显示区域中。 旧的图形表作为新图形表格的领导者。 在第二实施例中,图形片材设置有撕开的柔性引导件,其用于从存储卷轴组件展开纸张并且将图形纸张与自动售货机的表面上的显示区域对准。 在第三实施例中,具有间隔开的图形区域组的细长图形片材被卷绕在显示区域的相对侧上的一对隔开的卷轴组件上。 用于旋转卷轴的驱动机构被提供以选择性地将图形组中的选定位置定位到与显示区域对齐。 提供了用于选择性地激活驱动机构以将所选择的图形组定位在显示区域中的控制器,并且可以包括用于自动激活驱动机构以改变图形组或适当的遥控器和检测器组合的定时器,以便选择性地 通过远程命令信号更改图形。
