Description

  The present invention relates to a card inspection apparatus that inspects a card-shaped recording medium using a plurality of measurement apparatuses.

  In an inspection process for a card-shaped recording medium, an inspection based on inspection data by a plurality of measuring devices is generally performed (for example, Patent Document 1).

  Thus, when inspecting a card flowing continuously on the transport path using a plurality of measuring devices, inspection data in each measuring device is obtained for the same card.

  For example, consider a case where an inspection is performed using two measuring devices (A) and (B). FIG. 2 is a conceptual diagram of a card inspection apparatus that performs inspection using two measuring apparatuses. Referring to FIG. 2, when the card 11a is inspected by the measuring device 12a and then inspected by the measuring device 12b, if the card interval is shortened, the card 11a is checked with the next card before reaching the measuring device 12b. A certain card 11b reaches the measuring device 12a. As a result, the data belonging to the card 11a and the data belonging to the card 11b reach the PC (personal computer) 14 alternately. In other words, when the card interval changes, the order of the measurement data output from the two measuring devices changes and is sent to the PC 14.

  As described above, when determining whether the card is good or bad by combining the inspection data in the measuring device 12a and the inspection data in the measuring device 12b for one card 11a, the cards are regularly conveyed at regular intervals. In this case, there is no problem, but when the regularity is disturbed, a method for obtaining and inspecting data specified in the card 11a is necessary.

  At that time, in the conventional technique, the order is monitored by a host controller that is controlled by using a timing monitoring mechanism to identify which data belongs to which card. FIG. 3 is a conceptual diagram of a card inspection apparatus using a conventional timing monitoring mechanism. The timing monitoring mechanism 15 used at this time receives signals from position sensors arranged at regular intervals along the conveyance path, as shown by the white arrows continuing below the timing monitoring mechanism 15 in FIG. This is a mechanism for monitoring the position of the card based on it. As shown in the figure, based on the data from the timing monitoring mechanism 15, the PC 14 determines which card the data sent from the measuring device 12a and the measuring device 12b belongs to.

  However, the conventional technique as shown in FIG. 3 requires a complicated program in consideration of the conveyance timing, and the system of the entire card inspection apparatus is complicated. For example, in order to determine to which card one measurement data belongs even when an irregular conveyance such as when the card is momentarily jammed is performed, the measurement devices 12a and 12b It is necessary to arrange many sensors in between, and based on a large number of signals from each sensor, the measurement data by the measurement device 12a and the measurement data by the measurement device 12b belonging to a specific card are used as data from the same card. This is because it is necessary to judge.

  In this situation, an object of the present invention is to provide a simplified card inspection device having a determination function that data measured by a plurality of measurement devices belong to the same card. is there.

  In order to solve the above-mentioned problems, a card inspection system according to the present invention is a card inspection system for determining an inspection item based on data obtained by measuring a card-like recording medium continuously flowing on a conveyance path with a plurality of measuring devices. A counter that counts the number of passing sheets of the card-shaped recording medium provided in each of the measuring devices, and the measurement data output from each of the measuring devices includes the last of the passing number of sheets obtained by each of the counters. And an identification number adding means for adding a number of digits as an identification number, and measurement data in which the same identification number is added by collating the added identification numbers with respect to measurement data from a plurality of measurement devices And processing means for determining that the measurement data belongs to the same card-like recording medium.

  According to the present invention, there is no need for a card passing timing monitoring function. For example, a monitoring program for processing means using a PC can be simplified, and the entire system of the card inspection apparatus can be simplified.

  In particular, even when an instantaneous card jam occurs, measurement data belonging to one card is not regarded as measurement data of another card.

  That is, according to the present invention, it is possible to provide a simplified card inspection device having a function of determining that data measured by a plurality of measuring devices belong to the same card.

  A card inspection apparatus of the present invention is shown in a conceptual diagram in FIG. First, the card 11a flowing on the transport path is measured by the measuring device 12a. At the same time, the passing number counter 16a counts the number of passing cards. Next, in the identification number adding means 13a, the last digit of the number counted by the passing number counter 16a is added as an identification number to the measurement data obtained by the measuring device 12a and temporarily stored in the PC 14 as inspection data.

  Next, the card 11a flows on the transport path, and measurement is performed by the measuring device 12b. At the same time, the passing number counter 16b counts the number of passing cards. Next, the identification number adding means 13b adds the last digit of the number counted by the passing number counter 16b as an identification number to the measurement data obtained by the measuring device 12b and sends it to the PC 14 as inspection data.

  Thereafter, the PC 14 collates the identification numbers of the inspection data from the measuring device 12a and the inspection data from the measuring device 12b, thereby integrating the inspection data from the same card and determining the quality of the card.

  The identification means adding devices 13a and 13b may be incorporated in the PC 14 as processing means.

  By the way, the identification numbers added to the measurement data by the identification number adding means 13a and 13b change in the order of 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, for example, and the eleventh. Although the card number is changed as 1, 2,..., The identification number is the same within the change range of the actual card transport state, but one cycle (10 cards). The data of the cards that have been shifted as described above are mistakenly integrated as measurement data from the same card and are not used for determination of quality. This period can be easily changed by using a number other than a decimal number.

  Thus, a timing monitoring mechanism using a number of position sensors arranged along the transport path is not required, and a complicated control program associated therewith is also unnecessary. In other words, it was possible to easily recognize inspection data belonging to the same card even when card transportation was disrupted despite the fact that the system configuration was simple in response to irregularities in card transportation that could actually occur. .
