One end of each support arm 30 is connected to the machine body 10, and the two support arms 30 are disposed opposite to each other, and a side surface of the two support arms 30 facing each other defines an inner side surface 301. In practical applications, each support arm 30 may be a rectangular body, and the inner side surface 301 of each support arm 30 may correspond to a wide side surface.

Each supporting arm 30 is provided with an auxiliary fixing member 31, a guiding member 32, a pivoting member 33 and a fixing member 34, the guiding member 32 of each supporting arm 30 is correspondingly located on the inner side surface 301, the pivoting member 33 of each supporting arm 30 is connected with the fixing member 34, and each fixing member 34 can rotate relative to the corresponding supporting arm 30 through the connected pivoting member 33. The length and shape of the supporting arm 30 may be designed according to the size of the actual drawing platform 20, and are not limited to the illustration. In practical applications, one end of each supporting arm 30 may be fixedly disposed on the machine body 10, and the mechanical strength of the two supporting arms 30 connected to the machine body 10 can correspondingly bear the weight of the drawing platform 20.

The auxiliary fixing member 31 of each supporting arm 30 is located at one side of the inner side surface 301 of the supporting arm 30, and the auxiliary fixing member 31 is connected with the supporting arm 30 through the pivot assembly 33; the auxiliary fixing member 31 can be controlled (for example, manually or electrically) to rotate relative to the supporting arm 30 via the pivot assembly 33.

The guide member 32 of each support arm 30 is disposed on the side of the auxiliary fixing member 31 opposite to the inner side surface 301 of the support arm 30. The guide assembly 32 may have two rows of rollers 321, and a guide passage 32a is correspondingly formed between the two rows of rollers 321. The number of the rollers 321 and the arrangement thereof of each supporting arm 30 can vary according to the requirement, for example, the number of the rollers 321 can vary according to the length of the supporting arm 30, but is not limited to the illustrated embodiment.

In different embodiments, the drawing platform 20 can be correspondingly located on one side of the lower stage frame 12, and one side surface 201 of the drawing platform 20 can be used for carrying the member to be exposed. When the drawing platform 20 carrying the piece to be exposed is drawn out of the machine body 10 and correspondingly located on the two supporting arms 30, the drawing platform 20 can rotate counterclockwise relative to the two supporting arms 30, so that the side 201 of the drawing platform 20 carrying the piece to be exposed can substantially face the user.

Referring to fig. 8 and 14, in practical applications, each supporting arm 30 can be pivotally connected to the machine body 10 through a pivot structure 37, and each supporting arm 30 can be operated by a user or an electric control mechanism to rotate relative to the machine body 10, and each supporting arm 30 can move between a retracted position (as shown in fig. 14) and an extended position (as shown in fig. 1). When the two support arms 30 are located at the retracted position, the inner side surfaces of the two support arms 30 are disposed to face the machine body 10; the inner sides of the two support arms 30 are disposed to face each other when the two support arms 30 are in the deployed position.

Specifically, when the two supporting arms 30 are not needed, the related user or the related electric control machine can operate the two supporting arms 30, so that the two supporting arms 30 can rotate from the extended position shown in fig. 1 to the machine body 10 through the pivot structure 37, and then be converted into the retracted position shown in fig. 14, thereby avoiding the problem that the supporting arms 30 protruding from the machine body 10 collide with the related personnel or machines under unexpected conditions.
