<p>PURPOSE:To omit the retrimming and soldering processes and to facilitate an easy control process by obtaining the trimming value through a circuit having a trial process before a cutting process and then cutting a lead frame according to said trimming value. CONSTITUTION:The output of an oscillator 18 is applied to a counter 19 of four stages. The signal divided down 1/16 by the counter 19 is divided further by a counter 20 of 11 stages at the following place. Thus a pulse signal of 1Hz is delivered to servo as a clock of a second of a timepiece. This clock is applied to a time counter consisting of counters for seconds, 10sec, minutes, 10min, hour, day and month respectively. The time counter counts the 1-sec clocks successively and displays the time count data on a display circuit. While the counter 19 is presettable and increases equivalently the number of cycles of an oscillator 18 for each minute up to 0-16 by trimming. Then a trial is carried out before a trimming operation through a lead frame cutting action. Thus a signal similar to that obtained by trimming is set to the counter 19 a single pulse produced from a counter 21 every minute.</p> |
