- control unit 80 shown in FIG. 3 is a case where the signal output from the micro switch 28 is switched in the order of the OFF signal, the ON signal, and the OFF signal within a predetermined time, and the first OFF signal thereof. Is operating the drive unit 70 when it is determined that the output has been continuously output for the preset reference time or longer, but it is determined that "the first OFF signal has been continuously output for the preset reference time or longer". It is also possible to adopt a configuration that excludes "case” from the conditions.
- the present invention is not limited to the above, and it is needless to say that the present invention can be variously modified and implemented within a range not deviating from the gist thereof. ..
