The number of film cassettes 20 is multiple, and the multiple film cassettes 20 are slidably installed inside the frame 10, facilitating the pulling and placing of films in the film cassette 20. The multiple film cassettes 20 are arranged along the height direction.

[0029] The number of the conveying assemblies 30 is the same as that of the film cartridges 20. Each conveying assembly 30 is located at the upper end of a film cartridge 20 on the side far from the opening, and the conveying assembly 30 transfers the film in the film cartridge 20 to the conveying channel.

[0030] Please refer to Figures 3 to 6 , specifically, the conveying assembly 30 includes a mounting plate 31, a conveying driving member 32, a first transmission gear set 33, a second gear 34, and a third gear 35.

[0031] The conveying driving member 32 includes a motor 320 and a driving gear 321. The motor 320 is fixed to the inner side of the mounting plate 31, and the driving gear 321 is rotatably mounted on the mounting plate 31 and is in transmission connection with the motor 320. The first transmission gear set 33 includes a plurality of meshing gears, and the plurality of gears of the first transmission gear set 33 are rotatably mounted on the mounting plate 31. In this embodiment, the first transmission gear set 33 includes 6 meshing gears. The 6 meshing gears are arranged in the horizontal direction and extend from the side of the mounting plate 31 close to the opening to the side close to the conveying channel. The second gear 34 meshes with the first transmission gear set 33 and is used to transmit the power of the first transmission gear set 33 to the first conveying roller 40. The third gear 35 meshes with the first transmission gear set 33 and is used to transmit the power of the first transmission gear set 33 to the second transmission gear set 60.
