Abstract

PURPOSE:To facilitate the assembling work of a device, by providing a relay connected to the line and plural time set means and by exciting the relay only for a time set to time set means by control circuit to absorb the variance of the excitation time and the pulse width of dial pulses. CONSTITUTION:A dial pulse transmitting device 1 is provided with a relay 3 connected to a subscriber's telephone line 2, and a relay driving circuit 5 is connected to this relay 3. A control circuit 9 such as a microprocessor is connected to this circuit 5 through a register 6 and a data bus 7, and further, plural time set means 11A,11B...are connected to the control circuit 9 through a register 10. In case that the width of pulses generated from the relay 3 of the pulse transmitting divice 1 is regulated within a constant standard, a voltage applied to the register 9 is adjusted by a jumper plug 13 of set terminals 11d and 11e of means 11A,11B... to adjust the operation time of the relay 3 due to the control of the control circuit 9, therby absorbing the variance of the eaxcitation time and the pulse width.
