Description of the Related Art In an electric detonator, it is necessary to confirm that it is a good product at the time of manufacturing and shipping, and it is a principle to inspect the electric detonator immediately before use at a blasting site. In the inspection of non-delay electric detonators without the conventional electronic delay means, good or defective inspection is performed by passing a constant current small enough not to ignite the electric detonator to be inspected, and then mainly generating heat between the terminals of the electric detonator to be inspected. The drop voltage generated in the resistance element was measured to check whether the drop voltage was within a predetermined range. However, the electronic delay electric detonator cannot be inspected as described below by simply passing a minute current.

When the start switch 49 is turned on after connecting the terminals 11 and 12 to the terminals 34 and 35, turning on the power switch 26 and making each unit operable, the control unit 38 starts operating. The control unit 38 is composed of a microcomputer and sequentially performs programmed operations. First switch 3
6 is turned on, the switches 28 and 42 are turned off, and the resistance value of the resistor 37 is set to be sufficiently large with respect to the load connected to the terminals 34 and 35.
0 mA is supplied to the electric detonator 48. At this time, terminal 3
The voltage between 4 and 35 is detected by the voltage detection unit 44, and the input voltage can be amplified in the voltage detection unit 44 to a voltage at which it is easily detected, if necessary, and this detection voltage is taken into the control unit 38. In rare cases, it is judged whether or not it is normal. This supply current is such that the diode of the rectifier circuit 14 in the electric detonator 48 cannot be turned on, and the input resistor 1
A current flows only in No. 3 and the voltage drop caused thereby is near a predetermined value, for example, 170 mV (145 mV when the leg of the electric detonator 48 is not passed).
It is determined that 3 is correctly connected.

If the detection voltage is too high, it is determined that the input resistor 13 is disconnected and that the connection is defective.
If it is judged as defective, the display unit 45 displays an input resistor defect display, and if the input resistor 13 is removed, if the inspection is continued as it is, a large amount of electric energy will be stored in the energy storage capacitor 15 and actually, Since the ignition powder 21 may be ignited, the subsequent inspection is stopped.

中止する。When it is determined that the inspection of the input resistor is normal, the control unit 38 turns on only the switch 28, turns off the switches 36 and 42, and the rectifier circuit 1 of the electric detonator 48.
A current, for example 180 mA, at which a current barely flows through the diode 4 is supplied to the electric detonator 48. At this time, if the rectifying circuit 14 is normal, the two diodes in series are turned on, and the voltage between the terminals 34 and 35 is about 2.2V.
(It is about 1.75V without a leg). Terminals 34, 35
The voltage between them is detected by the voltage detection unit 44, taken into the control unit 38, and it is determined whether or not it is normal. That is, if the predetermined voltage is too low, a short circuit has occurred in the rectifier circuit 14, and if it is too high, the connection is broken, and an erroneous connection such as is detected.
The display unit 45 displays that the rectifier circuit 14 is defective. When the diode is short-circuited, electric energy is excessively stored in the energy storage capacitor 15, and later,
Since the ignition powder may be ignited, further inspections will be stopped.

示する。When it is determined that the rectifying circuit 14 is normal, the control unit 38 turns on the switches 28 and 42 and turns off the switch 36 so that the energy storage capacitor is set even if the set time of the electronic timer 17 is maximum. The electric energy stored in 15 does not ignite the electric detonator 48, but supplies to the electric detonator 48 a current, for example, 270 mA, which is sufficient to operate the electronic timer 17. By the above current control and supply of this current, the terminals 34, 3
The voltage between 5 changes, for example, as shown in FIG.
The supply of 0 mA causes the charge to be stored in the capacitor 15 relatively quickly, and the voltage between the terminals 34 and 35 rises. A predetermined time from the start of supplying this current, for example, about 5 to 6
The voltage between the terminals 34 and 35 when ms has passed is detected by the voltage detection unit 44. When this voltage is, for example, 3.3 V (2.6 V without a leg), it is determined that the capacitor 15 is connected and the capacitance value is normal. If the voltage is too low, the capacitance value of the capacitor 15 is too large and the inspection is performed as it is. If it continues, the electric detonator 48 may be ignited, so the inspection is stopped and the display unit 45 displays that the capacitor 15 is defective.

は比較的難かしい。When the capacitor 15 is normal, the predetermined current, for example, 270 mA is continuously supplied as it is. The electronic timer 17 normally starts operating at about 3V, for example. If the electronic timer 17 is normal, the electronic switch 18 is triggered at least until the maximum delay time of the electronic timer 17 has elapsed. Therefore, if normal, the electric energy of the capacitor 15 is supplied to the heating resistor element 19, and the voltage between the terminals 34 and 35 drops relatively rapidly. However, if the electronic switch 18 is defective, its connection is defective, or incomplete, the capacitor 15
Is not supplied to the heating resistance element 19 at all, or the supply speed thereof is too slow. Therefore, it is judged from the state of the voltage drop between the terminals 34 and 35 whether it is good or bad. In this case, since the voltage drop between the terminals 34 and 35 in the normal state is relatively rapid, the control unit 38 detects the start of the voltage drop and then the terminal 34 within a predetermined very short time thereafter. , 35, it is relatively difficult to detect whether or not it falls to a predetermined value.

The voltage is held so that the energy storage capacitor 15 is prevented from accumulating electric energy such that the electric detonator 48 is ignited.

In particular, it is easy to detect the time when the trigger is applied to the electronic switch at the terminals 34 and 35 and inspect whether the voltage of the terminals 34 and 35 becomes the predetermined value or less within a predetermined time since the period is short. It is difficult to do so, but as described above, the voltage drop state between the terminals 34 and 35 when the electronic switch is turned on is compared with the standard voltage drop state automatically created by the voltage drop. It can be easily inspected.
