    • An operator panel for a data input unit has a printed circuit board on which key switches corresponding to a number of commodities are arrayed. A flexible sheet is bonded over the keytops of the key switches. Photographs depicting the external appearance and shape of the commodities, or sketches showing the characteristics of the commodities, are printed on the flexible sheet at positions overlying respective ones of the keytops. The sheet has enough flexibility to enable operation of the key switches without hindrance. To input data relating to a desired commodity, an operator finds the photograph or sketch of the commodity on the flexible sheet and presses this portion of the sheet, thereby pressing the underlying commodity key switch to effect the entry of the data.
    • 用于数据输入单元的操作面板具有印刷电路板,在其上排列与多个商品对应的按键开关。 柔性片粘合在钥匙开关的键盘上。 描述商品的外观和形状的照片或显示商品特征的草图被印刷在柔性片材上,覆盖相应的键顶。 该片材具有足够的灵活性,可以无障碍地启用钥匙开关的操作。 为了输入与期望的商品有关的数据,操作人员在柔性片材上找到商品的照片或草图并按压片材的该部分,从而按下下面的商品钥匙开关来实现数据的输入。
