The playing card identification device 1 includes a card sending unit 2 and a number of sensors for detecting the number of pumps A (hereinafter referred to as “force A”) sent out from the card sending unit 2. , Type mark detector that detects the type mark (mark) of card A 4 A control unit 9 having an identification unit 5 for identifying what kind of force (type) the card A is based on the detection result from the type mark detection unit 4, and a sorting unit for sorting the card A 7, a display unit 8 composed of a monitor, and a specified number setting unit 37.

The card sending section 2 includes a set guide section 10 for stacking and setting the cards A, and a sending means 11 provided at the bottom of the 10 and configured to send out the lowest card A on the bottom. The card A sent out by the card 11 has an appropriate rotation resistance for lightly holding the card A at the outlet of the card guide portion (front wall) 13. A sphere for preventing the card A from being overlapped and sent. The card A sent from the sending roller 11 is sandwiched between the pair of rollers, and the card is sent out. The card is sent twice as fast as the sending speed of the sending roller 11 (2 or 3 times by changing the setting). It can be switched to either one of them.) It is composed of a pull-in sending unit 15 having a high pull-in speed.

The draw-in speed of the draw-in / feed-out unit 15 is set to be faster than the card send-out speed of the card send-out roller 11. Therefore, cards are sent out at appropriate intervals. As a result, when the card is passing, the laser beam or the red LED beam emitted from the light beam irradiating section 17 is interrupted in the number detection sensor 3, the light beam detecting section 18 does not sense the light beam, and the card passes. Then, since there is an interval between the next card and the laser beam, the laser beam hits the light beam sensing unit 18 and it is detected that one card has passed.

The number of cards A passed (the number of cards sent) is counted based on the detection signal of the number-of-sheets detection sensor 3.

The surrounding wall of the set guide part 10 is made of a transparent material, and the part where the card travels up to the card stock parts 21 and 22 is made of a transparent material on the front side.

Also, a method of reading the difference in reflectance between the type marks may be used.

Also, it is good to use a two-dimensional sensor and read the mark two-dimensionally (as a surface) at a time. This may be achieved by a method in which the shape of a type mark is stored by a CCD camera or the like, and the shape of the type mark is identified by comparing it with a previously stored type mark.

Also, a method of identifying the number of rows of marks, the color and the number may be used. This means that the mark has one row (1, 2, 3), the mark has two rows (4, 6), the mark has three rows (5, 7, 8, 9, 10), and the rows are consecutive Is (J, Q, K), which should be identified as a column rather than a mark. It is better to identify the color red as a diamond or a heart, and black as a club or a suede, detect numbers and marks and compare them as a whole to identify them. The identification unit 5 compares the detection data of the type mark detection unit 4 with the type mark data stored in the type mark storage unit 28 in advance to identify the type of the detected card. When there is an excess or deficiency of a card, the card is displayed on the display unit 8 and a notification buzzer 32 sounds. The display contents include displaying with a playing card, displaying marks and numbers, and the like. It is also good to display the counted number of cards.

FIG. 1 shows an example in which two of the missing playing cards are displayed as playing cards. In addition to the above, the display of an abnormal playing card may be a number and a single mark.

The display of the count value includes displaying the counted number value, displaying a predetermined number value in advance, and displaying the counted number value next to it.

FIG. 4 shows another display method on the display unit 8.

Insufficient cards (diamond 5) are indicated by marks and numbers, and the specified number 52 and count 51 are displayed below.

In this case, it indicates that five diamonds are not enough. By the way, when the number of counts is 52, there are two diamonds, and when the number of counts is 53, there are more diamonds.

The specified number setting section 37 specifies only the number of decks to be set in the set guide section 10, and the number of cards is fixed at 5 or 2 per deck. If it is 5 decks, 5 X 5 2 = 260 sheets. Rotate the knob with your finger to display and set the number of decks. If up to two digits can be set, two knobs for one digit and two digits are provided.

Counting and identification is done for each unit deck (games are usually played using multiple decks). The playing card is sent and counted. The card is identified. If there is no abnormality, the card of the next unit deck is sent and counted and identified. If there is an abnormality, the next unit deck is not sent out and the abnormality is notified.

The specified number setting section may set the number of decks and the number of cards. It can respond to the change of the specified number.
