Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a test mark card used for adjusting the detection sensitivity and detection timing of a card reading device, particularly a card reading device that optically reads marks.

Generally, a card reading device is known that records information as a mark on the card by filling in a predetermined frame on the card with a black pencil or the like, and optically reads this mark to decipher the content of the information. ing.

By the way, this type of card reading device only detects with high precision the presence or absence of a mark written in a predetermined frame as information, and uses a test mark card to avoid erroneously detecting stains due to deterioration as marks. Detection sensitivity and detection timing are adjusted.

However, conventionally, when making adjustments, multiple test mark cards were printed with marks that should be detected and marks that should not be detected, covering three types of check items: mark density, size, and marking position. Because of the conventional method, a large amount of time was spent on adjustment work, resulting in poor work efficiency.

The present invention has been made in view of the above-mentioned conventional drawbacks, and one embodiment thereof will be described below with reference to the drawings.

In Fig. 1, a test mark card 1 has a plurality of mark entry frames 2, 2, ... (hereinafter simply mark entry frames) using colors that are not detected by the card reading device (so-called drop-out colors). (referred to as frame 2) is printed at a predetermined position.

3 is a first mark printed within the mark writing frame 2 as a mark of density and size that must be detected by the card reading device;
are printed at different positions within a plurality of mark writing frames 2, including the limit density and size that the card reading device must detect, as shown in FIG.

4 is a second mark printed in the mark writing frame 2 as a mark with a density that should not be detected by the card reading device, and the second mark 4 is detected by the card reading device as shown in FIG. The markings are printed at different positions within the plurality of marking frames 2, including a density limit that should not be used.

5 is a third mark printed within the mark entry frame 2 or beyond the mark entry frame 2 as a mark of a size that must not be detected by the card reading device, and the third mark 5 is shown in FIG. As shown, a plurality of marks are printed at different positions in the mark entry frame 2, including the limit size that the card reading device must not detect within the mark entry frame 2.

6 is a fourth mark printed outside the entry frame 2 as a mark that must not be detected by the card reading device, and this mark 6 is at the limit position that the card reading device must not detect, as shown in FIG. are printed at different positions between the multiple mark entry frames 2.

The present embodiment is configured as described above, but in order to adjust the detection sensitivity and detection timing of the card reading device using the test mark card 1, the first to fourth marks printed on the test mark card 1 must be adjusted in advance. Since the position of the mark is known, it is only necessary to have the card 1 read by the card reader once.

That is, if the card reading device detects only the first mark, it means that the card reading device is correctly adjusted, and if one of the other second to fourth marks is also detected. It is immediately clear that the cause is either detection sensitivity or detection timing, as well as poor adjustment.

In addition, in the above embodiment, the three types of mark density, size, and writing position are printed so that both the detection sensitivity and detection timing of the card reading device can be checked. When checking one of these marks, it is not necessary to print all three types of marks.

The test mark card of the present invention is as described above in detail, and has the following features:
It has the feature and advantage that detection timing can be adjusted efficiently in a short time.

Claims (1)

[Claims] 1. A test mark card printed with two or more types of marks among marks with different densities, marks with different sizes, and marks with different writing positions. 2. The test mark card according to claim 1, in which marks with different densities, marks with different sizes, and marks with different writing positions are all printed.
