## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims the priority benefit of Taiwan application serial no. 100136752, filed on Oct. 11, 2011. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a printer, and more particularly, to a printer with a laminating function.
2. Description of Related Art
In offices today, printers and copiers are indispensable. When a document or photograph needs to be laminated, usually an additional laminating machine is used to perform lamination.
Laminating machines are not frequently used, and require a space to be placed. Thus, in order to save space, Taiwan Patent No. 1265857 discloses a printer combined with a laminating function. The aforementioned printer has two film rollers installed within specifically for laminating. After a document is fed into the printer, the document can be sent toward the two film rollers to perform laminating after printing or without printing. The printer can be used for only printing, only laminating, or both printing and laminating.
The printer respectively disposes two mechanisms for printing and laminating in the same body so that the printer can have both printing and laminating functions. Therefore, not only does the printer require a larger volume to store the printing and laminating structures, the production cost is also higher.
SUMMARY OF THE INVENTION

DESCRIPTION OF EMBODIMENTS
FIG. 1 is a schematic view of a printer according to an embodiment of the invention. A printer 100 of the embodiment includes a body 110, a printing mechanism 120, and a fixing mechanism 130. The body 110 includes a first transporting track 112. The printing mechanism 120 and the fixing mechanism 130 are disposed in the body 110. The first transporting track 112 respectively passes through the printing mechanism 120 and the fixing mechanism 130.
When the printer 100 executes a printing function, paper will transport from the first transporting track through the printing mechanism 120. When the paper passes through the printing mechanism 120, toner will adhere to the fibers of the paper. At this point, the toner on the paper will easily depart from its original position if affected by an external force. Thus, the paper that passed through the printing mechanism 120 will enter the fixing mechanism 130 so that the toner will fuse and permeate into the fibers of the paper. This way, the toner will be forever fixed onto the paper.
In the embodiment, the fixing mechanism 130 includes a heating mechanism 132 and a pressurized mechanism 134. The first transporting track 112 is located between the heating mechanism 132 and the pressurized mechanism 134. The heating mechanism 132 provides a toner fixed temperature or a laminating temperature according to need, and the pressurized mechanism 134 provides a toner fixed pressure or a laminating pressure according to need. The first transporting track 112 can transport objects that are to be printed or laminated, such as paper or films.
The user can first set to perform a printing procedure or a laminating procedure. When the user desires to use the printer 100 to perform the printing procedure, the user feeds paper into the printer 100, and the paper will first pass through the printing mechanism 120. Through the printing mechanism 120, toner is distributed on the paper. Then the paper enters the fixing mechanism 130, and the heating mechanism 132 provides a toner fixed temperature for the paper, and the pressurized mechanism 134 provides a toner fixed pressure for the paper. Through the fixing mechanism 130 heating and pressurizing the paper, the toner is fixed onto the paper.
When the user desires to use the printer 100 to perform the laminating procedure, the object to be laminated is covered with a film and fed into the printer. When performing the laminating function, the printing mechanism 120 does not operate. When the film passes through the fixing mechanism 130, the heating mechanism 132 provides a laminating temperature for the film, and the pressurized mechanism 134 provides a laminating pressure for the film. Through the fixing mechanism 130 heating and pressurizing the film, the lamination is complete. That is to say, the printer 100 of the invention adjusts a temperature and pressure of the fixing mechanism 130 according to need to complete a toner fix function or a laminating function.
In detail, the heating mechanism 132 includes a heating roller 132a. The heating roller 132a includes a heating tube 132b. The heating tube 132b is the heat source allowing the heating roller 132a to provide the toner fixed temperature or the laminating temperature. However, the heat source for the heating roller 132a is not limited thereto. In addition, the printer 100 includes a control module 140. The control module 140 is electrically connected to the heating mechanism 132, so as to control the heating mechanism 132 to provide the toner fixed temperature or the laminating temperature according to need.
The pressurized mechanism 134 includes a pressurized roller 134a, so that when the object to the printed or laminated passes through the fixing mechanism 130 through the first transporting track, it will be located between the heating roller 132a and the pressurized roller 134a. The printer 100 of the embodiment allows the object passing through to receive the toner fixed pressure or the laminating pressure through the pressurized roller 134a pressing against the heating roller 132a. In addition, the pressurized roller 134a includes an elastic surface layer 134b. An elasticity of the elastic surface layer 134b allows the pressing between the heating roller 132a and the pressurized roller 134a to be even tighter.
In the embodiment, the pressurized mechanism 134 further includes a first spring 134c, a base 134d, a second spring 134e, and a cam 134f. Two ends of the first spring 134c are respectively connected to the pressurized roller 134a and a side of the base 134d. The base 134d is hinged to the body 110. Two ends of the second spring 134e are respectively connected to the other side of the base 134d and the body 110. Since the cam 134f contacts the base 134d, rotating the cam 134f can adjust the position of the base 134d. This further adjusts the pressure the first spring 134c provides towards the pressurized roller 134a, so that the pressurized mechanism can provide the toner fixed pressure or the laminating pressure.
In the embodiment, the cam 134f can be rotated manually, so as to adjust the pressure provided by the pressurized mechanism 134. Of course, the control module 140 can also be electrically connected to the pressurized mechanism 134 to rotate the cam 134f, so as to change the pressure provided by the pressurized mechanism 134.
In addition, the printer of the embodiment further includes a rod 150, connected to the pressurized mechanism 134. When the object to be printed or laminated is jammed in the first transporting track 112 and lamination or printing can not be completed, the user can move the rod 150 so that the pressurized mechanism 134 can move to an open position relative to the heating mechanism 132. This way, the object to be printed or laminated can be taken out.
FIG. 2 is a schematic view of a printer according to another embodiment of the invention. A body 210 of a printer 200 of the embodiment includes a first transporting track 212 and a second transporting track 214. The second transporting track 214 passes through the fixing mechanism 230. The first transporting track 212 passes through the printing mechanism 220 and the fixing mechanism 230. As seen in FIG. 2, the first transporting track 212 meets with the second transporting track 214 before entering the fixing mechanism 230, and the first transporting track 212 and the second transporting track 214 will enter the fixing mechanism 230 as the same track to connect through an exit 216 of the body 210. The difference between the embodiment and the previous embodiment is in the embodiment of FIG. 1, regardless of executing a printing or laminating function, both use the first transporting track 112 to transport the object to be printed or laminated. As seen in FIG. 2, the track for executing the laminating function and the track for executing the printing function are separated. The second transporting track 214 is used as the track to transport film when executing the laminating function. The first transporting track 212 is used as the track to transport paper when executing the printing function.
FIG. 3 is a schematic view of a fixing mechanism of a printer according to yet another embodiment of the invention. The fixing mechanism 330 of the embodiment uses a magnetic method to provide pressure. In detail, the fixing mechanism 330 includes a heating mechanism 332 and a pressurized mechanism 334. The pressurized mechanism 334 includes a pressurized roller 334a, a first spring 334b, a magnetic base 334c, a second spring 334d, and an electromagnet 334e. Two ends of the first spring 334b are respectively connected to the pressurized roller 334a and a side of the magnetic base 334c. The magnetic base 334c is hinged to the body 310. Two ends of the second spring 334d are respectively connected to the other side of the magnetic base 334c and the body 310. The electromagnet 334e is disposed on the body 310 and corresponds to a position of the magnetic base 334c. 
In the embodiment, the magnetic force of the electromagnet 334e is adjusted to change the distance between the magnetic base 334c and the electromagnet 334e. This way, the deformation of the first spring 334b is affected so as to further change the force applied towards the pressurized roller 334a by the first spring 334b. As a result, the pressurized mechanism 334 can provide a toner fixed pressure when printing, or a laminating pressure when laminating.
FIG. 4 is a schematic view of a fixing mechanism of a printer according to still another embodiment of the invention. In the embodiment, the fixing mechanism 430 uses a gear wheel and a rack to change pressure. The fixing mechanism 430 includes a heating mechanism 432 and a pressurized mechanism 434. The pressurized mechanism 434 includes a pressurized roller 434a, a gear wheel 434b, a rack 434c, and a spring 434d. 
In the embodiment, the gear wheel 434b meshes with the rack 434c. Two ends of the spring 434d are respectively connected to the rack 434c and the pressurized mechanism 434. In the embodiment, a position of the gear wheel 434b in the printer does not change. Rotating the gear wheel 434b can change the position of the gear wheel 434b relative to the rack 434c. This changes the pressure applied to the spring 434d by the rack 434c, which causes the spring 434d to press against the pressurized roller 434a at a different pressure. As a result, the pressurized mechanism 434 of the embodiment can provide the toner fixed pressure or the laminating pressure.
FIG. 5 is a schematic view of a fixing mechanism of a printer according to still another embodiment of the invention. Referring to FIG. 5, in the embodiment, the fixing mechanism 530 includes a heating mechanism 532 and a pressurized mechanism 534. The pressurized mechanism 534 includes a pressurized roller 534a, an elastic surface layer 534b, a first spring 534c, a base 534d, a second spring 534e, a rod 534f, and a restricting element 534h. The elastic surface layer 534b covers the pressurized roller 534a. Two ends of the first spring 534c are respectively connected to the pressurized roller 534a and a side of the base 534d. The base 534d is hinged to the body 510. Two ends of the second spring 534e are respectively connected to the other side of the base 534d and the body 510. An end of the rod 534f is hinged to the pressurized roller 534a by a pivot 534i. The other end of the rod 534f is located outside the body 510. The rod 534f includes a press portion 534g, wherein the press portion 534g presses against the base 534d. The restricting element 534h is fixed to the base 534d and the pivot 534i is located in the restricting element 534h. The restricting element 534 is used to restrict the movement distance of the pivot 534i. 
When no pressure is applied to the rod 534f, a pressure exists between the pressurized roller 534a and the heating mechanism 532. Since the body 510 includes an opening 512 for the rod 534f to move up and down, in the embodiment, when an exposed portion of the rod 534f outside the body 510 is rotated up, the rod 534f is restricted by the opening 512 of the body 510 to only move a slight amount. At this point, the rod 534f will use the contact point with the body 510 as the fulcrum, so that the rod 534f located in the body 510 will move slightly downwards. Since the rod 534f is hinged with the pressurized roller 534a, the first spring 534c and the second spring 534e will slightly compress. Since the pressurized roller 534a includes the elastic surface layer 534b, even though the axis of the pressurized roller 534a is slightly away from the axis of the heating mechanism 532, the pressurized roller 534a still contacts the heating mechanism 532. Herein, the pressure between the pressurized roller 534a and the heating mechanism 532 is lowered. Thus, rotating the rod 534f can adjust the elasticity of the first spring 534c or the second spring 534e towards the pressurized roller 534a. This way the pressurized mechanism 534 can provide the toner fixed pressure or the laminating pressure.
In addition, if the paper or object is jammed by the pressurized roller 534a and the heating mechanism 532, in the embodiment, the portion of the rod 534f exposed outside the body 510 can be rotated downwards. Since the opening 512 of the body 510 allows the rod 534 to be rotated down, the press portion 534g will press down against the base 534d so that the second spring 534e is compressed. Since the pivot 534i between the pressurized roller 534a and the rod 534f is restricted by the restricting element 534h, the first spring 534c does not extend. Thus, in this condition, the pressurized roller 534a will move with the second spring 534e being compressed, away from the heating mechanism 532. This way the jammed paper can be removed.
To sum up, the printer of the invention adjusts a temperature and pressure of a fixing mechanism originally disposed in the printer to provide the conditions for executing a toner fix function or a laminating function. This way the printer of the invention does not require an additional laminating mechanism and can still simultaneously have both a printing function and a laminating function. Since an additional laminating mechanism is not required, the printer not only maintains its original volume, but also does not require additional cost because of the new laminating function.
Although the invention has been described with reference to the above embodiments, it will be apparent to one of the ordinary skill in the art that modifications to the described embodiment may be made without departing from the spirit of the invention. Accordingly, the scope of the invention will be defined by the attached claims not by the above detailed descriptions.
