Claims

[Scope of Claim for Utility Model Registration] 1. A human body presence/absence detection means for detecting the presence and departure of a human body in front of the urinal, and a period from when the presence of a human body is detected by the human body presence/absence detection means until the departure is detected. If the first time period has elapsed, a pre-use cleaning request signal is output, and if a second period of time has elapsed before detachment is detected after the first time period has elapsed, a post-use cleaning request signal is output. a signal processing unit that outputs the signal; a cleaning switch operating means that is driven by a motor to operate a cam to turn on a cleaning switch for the urinal; and the pre-use cleaning request signal output by the signal processing unit; Based on the after-use cleaning request signal,
An automatic flushing drive device for a urinal, comprising: a motor drive control section that controls driving of the motor of the flushing switch operating means. 2. The time during which the motor drive control unit drives the motor of the cleaning switch actuating means is longer when the after-use cleaning request signal is output than when the before-use cleaning request signal is output. The automatic flushing drive device for a urinal according to claim 1, characterized in that:
