PURPOSE:To realize a reduced energy consumption without causing a drop of a service by generating different voices automatically with a good timing in accordance witn coming in and out of a man. CONSTITUTION:In case when a man comes in, a mat switch is operated in order of 2 3, and a signal becomes an on-signal in order of A B. When the on- signal A is inputted to an input terminal 12, an output signal C becomes on. While the output signal C is on, a voice generating part generates ''Welcome!''. When the on-signal B becomes off, the output signal C becomes on. In case when a man comes out, the mat switch is operated in order of 3 2, and the signal becomes an on-signal in order of B A. When the on-signal B is inputted to an input terminal 13, an output signal D of an output terminal 22 becomes on. While the output signal D is on, the voice generating part generates ''Thank you for your coming''. When the on-signal A becomes off, the output signal D becomes off. |
