专利汇可以提供Input method of data专利检索,专利查询,专利分析的服务。并且PURPOSE: To utilize positively the simultaneous pressing of keys and to obtain the maximum signal with the minimum number of contacts, by separating plural contacts from each other along a prescribed direction and superposing and arraying mutually the contacts in another prescribed direction so that the adjacent contacts are simultaneously turned on by a single switch.
CONSTITUTION: A speed switch, a handle switch, etc. are set up on a key input part 2 on the body of a case of an electronic game machine and these switches are connected to liquid crystal panel 12 through an LSI chip 11 built in the body. Plural 1st contacts 13
1 W13
4 and 2nd contacts 16
1 W16
12 are arrayed so as to be separated from each other along the prescribed direction and so as to be superposed on each other in another prescribed direction so that adjacent contacts 13
1 W13
4 and 16
1 W16
12 are simultaneously turned on by the single switch. Key common signals KO
2 WKO
4 from the chip 11 are connected to the contacts 13
1 W 13
4 and key input signals KI
1 WKI
7 are connected to the other contacts 16
1 W16
12 . Consequently, the simultaneous pressing of the keys is positively utilized and the maximum signal is obtained with the minimum number of contacts.
