| 摘要 | PURPOSE: To reduce both the cost and the trouble factor of a keyboard by providing plural projection parts on the rear surface parts of key tops for identification of the information on the characters, symbols, etc., displayed on the surface parts of those key tops and forming plural switch members in response to said projection parts. CONSTITUTION: A keyboard main body 1 contains 24 key tops 2 of an approximately same form and is divided into a ten-key part and an auxiliary key part including a memory key, etc. Then 25 key switches 3 which work with press of those key tops 2 are formed at the positions opposite to the rear surface sides of the tops 2. Each switch 3 contains 9 switch members. Then plural projection parts 21 are provided on the rear surfaces of the tops 2 for identification of the information on the characters, symbols, etc., displayed on the surface parts of the tops 2. When a user pushes a key top 2, a switch member set at the position opposite to a part 21 works for input of the relevant information. COPYRIGHT: (C)1988,JPO&Japio |
