DATA INPUT DEVICE FOR INFORMATIION PROCESSING APPARATUS

摘要

A device for inputting data into an information processing apparatus using a communication cable. The device includes a sensing field including signal lines. The sensing field generates one or more signals when an object is proximate thereto. The device further includes at least one processor connected to the signal lines. The processor receives the signals and generates data based on the signals. The device additionally includes a port in communication with the processor for data output. The port is configured to connect to the cable end communicate the data over the cable to the information processing apparatus. The device includes a light source configured to illuminate keyboard symbols corresponding to areas of the sensing field. The device also includes an exterior surface covering the sensing field and obscuring the keyboard symbols from visibility unless the light source is providing illumination.

1. A device for inputting data into an information processing apparatus using a cable, the device comprising:
a sensing field including a plurality of signal fines, the sensing field generating one or more signals when an object is proximate the sensing field and communicating the signals over the signal lines indicative of location of the object; a processor connected to the signal lines in which the processor receives the signals from the sensing field and generates data based on the signals received; a port in communication with the processor which outputs data thereto, the port being configured to connect to the cable and communicate the date received from the processor over the cable to the information processing apparatus; a light source configured to illuminate keyboard symbols corresponding to areas of the sensing field; and an exterior surface covering the sensing field and obscuring the keyboard symbols from visibility unless the light source is providing illumination.
