Abstract

Keyboard 1 contains a 128 x 128 matrix of Chinese character keys, each of which is adapted to be depressed by the operator to enter a code representative of the depressed character key into a computer. Keyboard 2, which contains a 16 x 16 matrix of "radical" keys, is provided for selecting any character keys on keyboard 1. Light source 3 illuminates all of the character keys on keyboard 1 through optical device 4. A plurality of optical masks one for each of the radical keys on keyboard 2 are provided in mask file 5. Upon depression of any radical key, the corresponding mask is moved from the mask file into the optical path.

Character Selection System for Chinese Character Keyboard

Keyboard 1 contains a 128 x 128 matrix of Chinese character keys, each of which is adapted to be depressed by the operator to enter a code representative of the depressed character key into a computer. Keyboard 2, which contains a 16 x 16 matrix of "radical" keys, is provided for selecting any character keys on keyboard 1. Light source 3 illuminates all of the character keys on keyboard 1 through optical device 4. A plurality of optical masks one for each of the radical keys on keyboard 2 are provided in mask file 5. Upon depression of any radical key, the corresponding mask is moved from the mask file into the optical path.

Assuming that Chinese character "*" on keyboard 1 is to be selected, first the operator depresses the radical key "*" on keyboard 2 to move the corresponding mask 6 into the optical path causing only those character keys on k keyboard 1 which have the radical "*" to be illuminated. Thus, the operator can find "*" key among the illuminated keys. If he wants to further restrict the scope of his search, he may further depress the radical key "*" to move the corresponding mask 7 into the optical path allowing only those character keys which have both radicals "*" and "*" to be illuminated. Similarly, further depression of the radical key "*", if desired, allows only those character keys which have radicals "*", "*" and "*" to be illuminated. Thus, the operator can easily select the desired...
