INSTRUCTIONS: [Technical field to which the invention pertains], particularly an object having a platen cam for resetting. The present invention relates to an object carrying device that controls the inclination of an article to provide an automatic setting. Eight [Prior Art] In general, the paper feeding in the printer is all used to take the paper to rotate the paper to send the paper. 'This is the money-based printer must provide — apply force to the paper pick roller Between the paper and the paper to generate _ send _ need of the power. The object used to carry the green in the printer of the prior art is called the lifting paperboard, and an elastic crystal mold set under the lifting paperboard can provide the friction between the paper taking roller and the paper. Therefore, under normal operation, when the lord needs to replace or put the paper on the screaming age, the papermaker will pull it out, and the cardboard will be lifted by the force of the spring module, being topped. Lifting the cardboard often causes inconvenience when the user replaces the paper. Please refer to Fig. 1. Fig. 1 is a partial schematic view of a paper feed cassette 10 of a conventional printer. Referring to Figure 1, the paper feed cassette 1 will push a "^ hook 11 on the side wall 14 of the printer frame when pushed into the printer, and will drive a spring 12 when the hook 11 is pushed. While a support cylinder 13 is pulled up, the support cylinder π will lift a cardboard (not shown) to provide the pressure required to take the paper. However, this conventional structure is very complicated 'high cost and difficult to handle. Please refer to Fig. 2, which is a schematic view of another conventional paper feed cassette 20 of the printer. As disclosed in U.S. Patent No. 6,042,103, 7 1313224 (taken the button) on the side panel of the frame; the fine wheel 105 2 is in the movable mode. The guiding module 1G6 is provided in a movable manner. (i.e., the guide groove) is driven to rotate on the second rotating shaft 丨04 while the article feeder 107 is moving. Referring to Figs. 3 and 4®, the lean/face feeding member 107 is fed from the object feeding position 乂7. The object map shown in Fig. 3 is the object-feeding position of the guide groove provided by the guide plate 1G6. Sliding causes the platen cam (10) to be forced to rotate R1 in the second direction of the clock, as shown in Fig. 1 2 3, the first position, the a position, and the read position 1G6b. New meaning, the first position of the present invention - the position of the leg is clearly returned to the first position - the person familiar with the technology can easily derive the first position to purchase less than the second position after reading the content disclosed in this month 4, the embodiment of 106b, therefore, any first positional position of the wrist is not horizontal to the second position" is the spirit of the financial approval. Lin implements the shot, the plate cam 1〇5 series presents an "L," shape, and has another When a force is applied, the force exerts a force on the object carrier plate ι〇3 when the R1 is rotated clockwise. 1 U—\曰 is larger than the elastic force F1 provided by the elastic member 1〇1, so that the object carries 2 plates. 103, the first rotating shaft 1〇2 is rotated and pressed down. Finally, when the object feeding device 7 moves to the object placement position & and stops, the 1313224 of this embodiment rotates, and the sliding end l〇5a is fixed to the guiding module 1〇6. The second positioning position 106b of the guiding groove' makes the platen cam 105 unable to rotate, and at this time, the object bearing plate 103 cannot be lifted and will just assume a substantially horizontal state, so that the user can conveniently place the object 103a. The object carrying plate 1 〇 3 is placed, as shown in Fig. 5, which is shown in Fig. 5, which is the object feeding device of the object carrying device (10) of the present invention, which is located at the object placing position & schematic diagram. On the other hand, please refer to Figs. 3 and 6 simultaneously. Fig. 6 is a schematic view showing the movement of the article feeder 107 shown in Fig. 3 from the object placement position X2 to the object feeding position & As described above, when the object feeder 1〇7 is placed at the object placement position Χ2, the user can place the article 103a on the article carrier board 1〇3, after which the user reverses the object feeder 107 to the opposite side. When the other direction 〇2 of the direction D1 is moved, the sliding end l〇5a of the platen cam 105 slides from the second positioning position 106b of the guiding groove provided by the guiding module 1〇6 to the first positioning position 1〇6a. The platen cam 105 is forced to rotate & in the counterclockwise direction along the second rotating shaft 104. Since the first positioning position 106a is higher than the second positioning position, the force applying end 105b of the platen cam 1〇5 in the counterclockwise direction is gradually increased as the direction & The elastic force Fi provided by the element 101 causes the object carrying plate 1〇3 ✓a to rotate on the first rotating shaft 102 (clockwise direction). Finally, when the object feeder I. When moving in the direction D2 to the object feeding position & and stopping, the biasing end i 〇 5b of the platen cam 105 of the present embodiment will rise to a predetermined position, and the sliding end 1 will stop at the guiding provided by the guiding module 106. a first positioning position l〇6a of the slot, wherein the predetermined position is designed such that the sliding end 1〇5& does not contact the object 1〇3a to 11 1313224 to cause the pickup roller 108 in the printer (eg, the third The figure shows) normal operation. * "Unexpectedly, the guide module 1〇6 of the present invention is limited to the use of the guide groove to drive the cam 1〇5, and other mechanisms may be applied to drive the platen cam, for example, in its case 'guide 敝 1 () 6 and It is also within the scope of the present invention to detect the moving position of the object feeder 107 and generate a control signal to a motor to drive the rotation of the platen cam 105. The above is only a preferred embodiment of the present invention. The embodiment shows the scope of the solution and the scope of the invention according to the scope of the patent application of the present invention.
