<p>PROBLEM TO BE SOLVED: To provide a pulse generating circuit which can surely generate the pulse signals even when it's applied to any type of power voltage by using a connection circuit that can optionally set the electrical connection between the 1st and 2nd electrodes of each of transistors TR constructing a 2nd circuit. SOLUTION: Each of TRs 7 constructing a 2nd circuit secures an electrical connection state between an output terminal 19 and a terminal 17 via (n) TRs when a TR 6 conducts. Thereby, the electrical connection state is delayed between both terminals 19 and 17. A switch means 8 serving as a connection circuit is added to every TR 7. One of both ends of the means 8 is connected to one of both electrodes of the TR 7 with the other end of the means 8 connected to the other electrode of the TR 7 respectively. Then one of both electrodes of the TR 7 is short-circuited to the other electrode in response to the control signal that controls the operation of the means 8. Thus, it's possible to vary the width of the pulse signal which is outputted from the terminal 19 according to the state of the means 8.</p> |
