First Claim
1. A bar code reading device comprising:
- a transparent liquid crystal display means for displaying an image of a keyboard in a manual input mode;
a transparent touch sensor means formed on said liquid crystal display means for entering key-in data corresponding to portions thereof which are touched with reference to said image of a keyboard displayed on said liquid crystal display means;
a code reading means for, in a code reading mode, reading a bar code associated with an article by emitting a light beam through a window constituted by said liquid crystal display means and said touch sensor means, and for receiving therethrough a light beam reflected from the bar code; and
control means for selectively setting one of said manual input mode and said code reading mode, and for reading key-in data entered by said touch sensor means.

Abstract
A bar code reading device includes a code reading section for reading a bar code attached to an article by emitting a light beam through a window and receiving therethrough the light beam reflected from the bar code, and a manual input section for inputting article information by operation of a keyboard. In the bar code reading device, the manual input section includes a transparent liquid crystal display panel, a transparent touch sensor panel disposed on the liquid crystal display panel, and a control circuit for selectively setting one of a manual input mode and an automatic reading mode, driving the liquid crystal display panel so as to display an image of keyboard in the manual input mode and to erase the image of keyboard in the automatic reading mode, and reading key-in data entered by touching portions of the touch sensor panel with reference to the image of the displayed keyboard in the manual input mode. The light beam can be transmitted via the liquid crystal display panel and the touch sensor panel in the automatic reading mode.
