ABSTRACT:
A data buffer for a label reader system including a data processor. The label reader system includes at least one label reader unit, a first memory means, a second memory means, and a data processor. The first memory means is separately, switchably connected by gate means to a label reading unit, and to the data processor. The second memory means is connected to the data processor. The label reading unit provides a control signal to the gate means so that when data is being transferred between the label reading unit and the first memory means, the data processor then only can transfer data to and from the second memory means. When no data transfer is occurring between the label reading unit and the first memory means, data can then be transferred between and among the first memory means, and second memory means.
