The camera device 50 is located above the photo frame 910 of the printing and photo combination machine 90 ″, and the camera device 50 is used for photographing the identification card 100 carried in the transmission channel 912 of the photo frame 910.

To facilitate understanding of the present invention, the operation of the combined printing and photographing apparatus shown in fig. 1 to 8 will be described in detail below.

When the identification card 100 needs to be translated to a predetermined printing and photographing position, the first and second translation

upper driving wheels

931 and 933 are in initial positions (see fig. 8). A plurality of first translation upper driving wheels 931 are arranged perpendicular to the card direction, and a translation gap is formed between each first translation upper driving wheel 931 and the corresponding first translation lower driving wheel 932 so as to clamp one side of the card 100 and drive the card to translate; a plurality of second translation upper transmission wheels 933 are arranged in a direction perpendicular to the card direction, and a translation gap is formed between each second translation upper transmission wheel 933 and the corresponding second translation lower transmission wheel 934 so as to clamp the other side of the card 100 and drive the card to translate. At this point, the translating

upper drive wheels

931, 933 and translating

lower drive wheels

932, 934 act to transport the identification card 100.

When the card 100 is translated to the predetermined printing and when shooing position needs to be printed and shooed along transmission channel 921, third pivot 923 rotates to second direction of rotation, via third gear 9232 and first gear 9212 drive first pivot 921 rotates to make a plurality of first translation go up the transmission wheel 931 upset to the printing and the position of shooing, drive via fourth gear 9234 and second gear 9222 second pivot 922 rotates to make a plurality of second translation go up the transmission wheel 933 upset to the printing and the position of shooing. A plurality of first translating upper drive wheels 931 positioned parallel to the identification card direction such that the plurality of first translating upper drive wheels 931 avoid the identification card 100; a plurality of second translating upper drive wheels 933 are positioned parallel to the identification card orientation such that the plurality of second translating upper drive wheels 933 clear the identification card 100. That is, when the identification card at a predetermined printing and photographing position needs to be printed and photographed, the number of first translational upper drive wheels 931 and the number of second translational upper drive wheels 933 are opened. At this point, the baffle 942 enters the photoelectric sensor 944, and the sensor 940 generates and outputs a roll-to-bit signal. Subsequently, the camera device 50 located above the camera stand 910 takes a picture of the identification card 100 located at the pre-printing and photographing position, and the laser printing device prints the identification card.

When the certificate card 100 needs to be translated to leave a preset printing and photographing position after photographing and printing are completed, the third rotating shaft 923 rotates in a first rotating direction (the first rotating direction is opposite to the second rotating direction), the first rotating shaft 921 is driven to rotate through the third gear 9232 and the first gear 9222, so that the plurality of first translation upper transmission wheels 931 turn to an initial position, and the second rotating shaft 922 is driven to rotate through the fourth gear 9234 and the second gear 9222, so that the plurality of second translation upper transmission wheels 933 turn to the initial position. That is, when the card needs to be translated to reach or leave the predetermined photographing and printing position, the number of first translation upper driving wheels 931 and the number of second translation upper driving wheels 933 are reset (or closed). Subsequently, the translation module 930 sends out the identification card 100 in the original direction or the reverse direction.

Referring to fig. 5, the card flipping machine 30 ″ includes a translation mechanism and a flipping mechanism. The translation mechanism is configured to drive the card to translate; the fourth sensor 340 and the fifth sensor 350 are configured to cooperate to detect whether the card is in a predetermined translation position, that is, the fourth sensor 340 is configured to detect whether the translation front end of the current card exceeds the card flipping machine 30 "; the fifth sensor 350 is configured to detect whether the translated rear end of the current identification card exceeds the identification card flipping machine 30 ". The turnover mechanism is configured to turn over the identification card to turn over the current printing surface of the identification card from the first printing surface to the second printing surface. The third sensor 330 is configured to detect whether the card is flipped in a predetermined flipping position, i.e., the third sensor 330 is configured to detect whether the current flipping level of the card is present. It should be noted that in this embodiment, the detection principle of the second sensor 950, the third sensor 330, the fourth sensor 340, and the fifth sensor 350 is the same as that of the first sensor 940, and details are not repeated herein.
