The specific embodiment

Existing conjunction with figs. explanation the preferred embodiments of the present invention.

Consult Fig. 2, guide device 100 of the present invention is arranged on the business machine 1.Guide device 100 is to be used for pushing away flat correcting and to import a recording medium P to business machine 1.Recording medium P can be paper, transparency, egative film, photograph or envelope etc.

Consult Fig. 3 A and Fig. 3 B, guide device 100 mainly includes a rotating shaft 110, and keeps out element 120, a guide element 130, a sliding members 140, a roller 150, a friction element 160, one first spring 170, one second spring 175, a pallet 180 and a setting element 190.

Shown in Fig. 2, Fig. 3 A and Fig. 3 B, rotating shaft 110 is arranged on the business machine 1, and has a protuberance 111, a first end 112 and a second end 113, and simultaneously, the cross sectional shape of rotating shaft 110 is cross haply.

Keeping out element 120 is arranged on the first end 112 of rotating shaft 110,130 of guide elements are arranged on the second end 113 of rotating shaft 110, and guide element 130 is fixed on the business machine 1, simultaneously, shown in Fig. 3 B, guide element 130 also has the guidance part 131 of a strip.

Sliding members 140 is to be located in the rotating shaft 110 in the mode of sliding, and is adjacent to guide element 130, simultaneously, also has a sliding tray 141 and a guiding groove 142 on the outer surface of sliding members 140.Guiding groove 142 can be divided into shape groove 142a and oblique groove 142b two parts always again, and oblique groove 142b connects straight shape groove 142a, and extends to outside the sliding members 140.Specifically, sliding tray 141 slides on the guidance part 131 of guide element 130, and straight shape groove 142a and oblique groove 142b then slide on the protuberance 111 of rotating shaft 110.

Roller 150 also is located in the rotating shaft 110 with sliding type, and is keeping out between element 120 and the sliding members 140, and roller 150 is mainly used to leader record medium P to business machine 1.Especially, shown in Fig. 3 B, the inner section shape of roller 150 is corresponding to the star section shape of rotating shaft 110, and therefore, after roller 150 was located in the rotating shaft 110, it only can slide in rotating shaft 110, and can not relatively rotate by countershaft 110.

Friction element 160 is coated on the outer surface of roller 150, and can be made by the material that rubber etc. has a great friction coefficient, to increase its grasping force to recording medium P.

First spring 170 is arranged on keeps out between element 120 and the roller 150, and second spring 175 then is arranged between roller 150 and the sliding members 140.In the present embodiment, first spring 170 can be the spring with identical coefficient of elasticity with second spring 175.It should be noted that when sliding members 140 when rotating shaft 110 is slided, first spring 170 and second spring 175 can be compressed, thereby second spring 175, roller 150 and first spring 170 are slided in rotating shaft 110.

As shown in Figure 2, pallet 180 is arranged on the business machine 1, and is positioned under the roller 150 (friction element 160), with carrying recording medium P.Setting element 190 is formed on the side of pallet 180, and it can be used as the correcting benchmark of recording medium P.

In addition, as shown in Figure 2, also be provided with a detector 16 on the pallet 180 of business machine 1, whether it can be used for detection record medium P and is positioned on the pallet 180.

In addition, as shown in Figure 4, business machine 1 also has a cam 17, a gear train 18 and a motor (not shown).Gear train 18 is connected in the rotating shaft 110 of cam 17 and guide device 100, cam 17 roof pressure pallets 180.Motor connects gear train 18, with drive gear set 18, cam 17 and rotating shaft 110.

Next the function mode of guide device 100 will be described.

At first, consult Fig. 4, the user utilized the transmission of motor and gear train 18 earlier before placing recording medium P, made cam 17 rotate to discharge pallet 180 by the direction shown in the arrow A, and at this moment, pallet 180 will upwards rise by the direction shown in the arrow B.Then, recording medium P is placed on the pallet 180.Then, as shown in Figure 5, utilize the transmission of motor and gear train 18 again, make cam 17 by arrow A ' shown in direction rotate, so that press down pallet 180, at this moment, pallet 180 by arrow B ' shown in be directed downwards rotation, and recording medium P is by sliding under the direction shown in the arrow C under the roller 150 (friction element 160), simultaneously, rotating shaft 110 and roller 150 (friction element 160) also will rotate according to a first direction (clockwise direction) owing to the transmission of motor and gear train 18, get back to the home position to guarantee roller.Then, as shown in Figure 6, utilize the transmission of motor counter-rotating and gear train 18 again, cam 17 is rotated according to the direction shown in the arrow A, rise so that pallet 180 makes progress according to the direction shown in the arrow B, at this moment, the friction element 160 on the recording medium P contact roller 150.Simultaneously, as shown in Figure 6, rotating shaft 110 and roller 150 (friction element 160) are also pressed a second direction (counterclockwise) rotation owing to the transmission of motor counter-rotating and gear train 18, so that grasp the action of recording medium P.Shown in Fig. 7 A, the straight shape groove 142a of sliding members 140 slides earlier on the protuberance 111 of rotating shaft 110, and at this moment, the roller 150 in the rotating shaft 110 (friction element 160) only rotates and do not move, and enters in the business machine 1 so that recording medium P guided a little.When rotating shaft 110 turns to 160 when spending from 0 degree, shown in Fig. 7 B, the protuberance 111 of rotating shaft 110 enters to the oblique groove 142b of sliding members 140 from the straight shape groove 142a of sliding members 140.Then, shown in Fig. 7 C, after rotating shaft 110 is rotated above 160 degree, the oblique groove 142b of sliding members 140 slides on the protuberance 111 of rotating shaft 110, at last, the slip away protuberance 111 of rotating shaft 110 of the oblique groove 142b of sliding members 140, at this moment, sliding members 140 is because the guiding restriction of the guidance part 131 of guide element 130 and the pushing of protuberance 111 that be subjected to rotating shaft 110, and push second spring 175 by the direction translation shown in the arrow D, the roller 150 and first spring 170, and then make roller 150 (friction element 160) to rotate simultaneously and axially movable mode promotes to be positioned at recording medium P on the pallet 180, so that recording medium P carries out correcting by the setting element 190 that is positioned on pallet 180 sides, then, the recording medium P after correcting can successfully be inputed in the business machine 1.Be noted that at this, though the axial displacement of sliding members 140 is fixed, but guide device 100 can be looked the actual crooked or thickness degree of recording medium P and adopt first spring 170 and second spring 175 with different coefficient of elasticity, to adjust the distance that moves axially of roller 150.

Then, utilize the transmission of motor and gear train 18 again, cam 17 presses down pallet 180 with rotation, so that recording medium P breaks away from roller 150.At last, rotating shaft 110 and roller 150 (friction element 160) rotate according to first direction (clockwise direction) owing to the transmission of motor and gear train 18 more again, make roller 150 and sliding members 140 can by the elastic force of second spring 175 and first spring 170 push and translation gliding to its home position, wherein, the protuberance 111 of rotating shaft 110 will enter among the oblique groove 142b and straight shape groove 142a of sliding members 140 successively again.

In addition, when the detector on the pallet 180 16 detected recording medium P once again, guide device 100 just repeated above-mentioned steps, so that push away flat correcting and import recording medium P to business machine 1.

Though the present invention discloses with preferred embodiment; but be not in order to limit the present invention; any those skilled in the art can make and changing and retouching not breaking away from the spirit and scope of the invention, so protection scope of the present invention is defined with accompanying claims.
