\"PushPhone_1\"<\/a><\/p>\n

\"PushPhone_2\"<\/a><\/p>\n

\"PushPhone_3\"<\/a><\/p>\n

In this telephone, a state\u00a0of the key matrix\u00a0is scanned by pull-down of signal lines, and\u00a0photocouplers are added\u00a0to act as a push\u2010button.<\/p>\n

\"TLP521\"<\/a><\/p>\n

TLP521-4 (4 units) x 4 packages<\/p>\n

\"Key<\/a><\/p>\n

The push\u2010buttons, “\u4fdd\u7559”, “\u30ad\u30e3\u30c3\u30c1”, “\u30ea\u30c0\u30a4\u30e4\u30eb”, are not used in this experiment.<\/p>\n

\"PushPhone<\/a><\/p>\n

The telephone\u00a0set is electrically<\/span> separated from the\u00a0controller circuit by photocoupler and relay units.<\/p>\n
