It is not necessary to tamper with the non-contact sensor, and it is still possible to determine that the disconnection is not connected to the device. , the difference between the intensity of the number assigned to a non-contact sensor is reduced (4).

The detection signals detected by the touch sensors (22a), (22b) and the probes (25a) to (25d) are sent to the signal processor; the computer (; 14) controls the entire device and processes the components according to the signal (2 3 Based on the data, it is determined whether or not the branch circuit wiring D and the single circuit wirings A to C and E are disconnected. The signal source (2 1), the non-contact sensors (2 2a ) and (2 2b), the signal processing component (23), and the computer (24) are respectively the signal sources of the inspection device shown in FIG. 4 (1 1 The non-contact sensors (1 2 a) to (1 2 d), the signal processing unit (1 3 ), and the computer (14) are the same, and the following mainly describes the differences. The probes (25a) to (25d) are, for example, pins having electrical conductivity, and are in contact with the ends of the branch circuit wiring D to detect the inspection signal. In the inspection apparatus shown in Fig., the probes (25a) to (25d) are used instead of the non-contact sensor (1 2 b) of the inspection apparatus shown in Fig. 4. Although there are individual differences, in general, non-contact sensors are higher in price than probes, and probes can be used to construct inspection devices at a low price. However, the non-contact sensor, such as the description, has the advantage that one non-contact sensor can be used to inspect a plurality of single circuits, so that in the inspection device shown in FIG. 5, the two are mixed. .口 t 牡 &lt; ',, 0

In the case of Fig. 5, one end of each of the single wirings A to C and one of the branch circuit wirings J) is allocated to the non-contact sensor (223). Further, on the touch sensor (22b), an end portion of a single circuit wiring and one end portion of the eight wirings D are allocated. On the other hand, the probes (25a) to (25d) are respectively assigned to the left and right of the branch circuit wiring D. And on the top? Inspecting the structure of the inspection device' First, configure each non-touch sensing (2 2 a ) and (1 2 b ), as shown in Figure 5, and in the Baoshi | on the branch circuit with _

The following is the same as the case shown in Fig. 4, in which the signal source is controlled by the computer (24) to cause an inspection signal. At this time, for example, the inspection signals are sequentially supplied to the respective circuit wirings A to e in the order of the single circuit wiring A - B - C - the branch circuit wiring D - the branch circuit wiring e. Thus, each of the non-contact sensors (22a) and (22b) and the probes (25a) to (25d) detect the inspection signal, and the signal processing component (23) performs the specified processing for the detected inspection signal. . The signal processing component (23) sends information of the inspection signals detected by the non-contact sensors (22a) and (22d) and the probes (25a) to (25d) to the computer (丨4).

Here, the 'computer (24) supplies the timing of the inspection signal to the circuit wirings A to E according to the signal source (21), and the timings of the inspection signals detected by the non-contact sensors (12a) to (12c), and the determination is broken. Whether there is a line. At this time, the determination of whether or not each circuit wiring A to E is disconnected can be based on each non-contact sensor (12a) and (12b), and each probe (25 〇 to (25 (1), whether it is double / It is sufficient to determine the inspection signal of the above-mentioned day order as a reference. That is, if the inspection signal is detected, it can be determined that the line is not broken, and if the inspection signal is not detected, it can be determined that the disconnection has occurred. In the case shown in FIG. 5, one end of the branch circuit wiring D is allocated to the contact sensors (22a) and (22b), and two are not allocated.

Further, in the inspection apparatus of Fig. 5, the distribution methods of the non-contact sensors (22) and (22b), and the probes (25a) to (25d) are variously considered. For example, in the example shown in Figure 5, although in the non-contact sensor (22 &amp;) and

At this time, the presence or absence of the disconnection, the intensity and specification of the detected signal are measured. One end, but it is also possible to assign 2 to be judged by comparing the detection limits for the sensors.

Further, in the example shown in FIG. 5, both the end portion of the single circuit wiring A and the end portion of the branch circuit wiring ' are assigned to the non-contact sensors (22a) and (22b). The probes (25a) to (25d) are assigned to all of the remaining ends, but the probes may be allocated to one of the end portions of the branch circuit wiring 1), and the non-contact sensors may be assigned to the remaining ends. This day's non-contact sensing can also be assigned up to 2 ends.

Thus, in the inspection apparatus shown in Fig. 5, when a single circuit wiring and a branch circuit wiring are mixed, relative to ! The non-contact sensor distributes both the end of the single circuit wiring and the end of the branch circuit wiring, thereby reducing the number of non-contact sensors. Moreover, by arranging the probes at the remaining end portions of the branch circuit wiring, the number of non-contact sensors can be further reduced. The above description has been made in terms of preferred embodiments of the present invention, but the present invention is of course not limited thereto. In particular, regarding the manner of distribution of the non-contact sensor, various forms can be considered without departing from the gist of the present invention, and since [industry availability], as described above, a smaller number can be used according to the present invention. Touch the sensor and check the circuit wiring of the midway branch or the circuit wiring that exists in the mixture. [Description of component number] 1 Signal source
