Referring to fig. 1, a schematic side sectional view of a conventional printing device is shown. The printing apparatus 1 includes a printing apparatus housing 10, a paper feed cassette 11, a printing module 12, a first paper feed path 13, a plurality of first paper feed roller groups 14, and a stapling apparatus 15. The printing device housing 10 has an upper surface 101 and a paper outlet 102, and the paper outlet 102 is exposed on the upper surface 101. The paper feed cassette 11 is provided in the printing apparatus housing 10, on which a plurality of sheets of paper P can be placed. The first paper feeding channel 13 is disposed in the printing device housing 10 and between the paper feeding cassette 11 and the paper outlet 102, and is capable of passing through a plurality of sheets of paper P. The first roller sets 14 are disposed on the first paper feeding path 13, and function to feed the sheets P in the paper feeding cassette 11 to the paper outlet 102. The printing module 12 is disposed on the first sheet feeding path 13 and functions to print an image on a plurality of sheets P. The binding device 15 is disposed on the upper surface 101 of the printing device housing 10 and covers the paper outlet 102, and the binding device 15 includes a binding module 151, a binding cassette 152, a second paper feeding channel 153, and a plurality of second paper feeding roller groups 154.
In the binding device 15, the second paper feeding channel 153 contacts with the paper outlet 102 on the printing device housing 10, so that the second paper feeding channel 153 is engaged with the first paper feeding channel 13 to allow the multiple sheets of paper P to pass through. The plurality of second sheet feeding roller groups 154 are disposed on the second sheet feeding path 153, and function to feed the sheets P from the first sheet feeding path 13 to the staple tray 152. The binding cassette 152 functions to hold a plurality of sheets of paper P, and the binding module 151 is located at one side of the binding cassette 152, for binding the plurality of sheets of paper P located on the binding cassette 152. The printing device 1 with the binding device 15 can utilize the binding device 15 to bind the plurality of sheets of paper P after the printing of the printing module 12 is completed, so that a user does not need to wait for the printing of the plurality of sheets of paper P to be completed and then manually bind, thereby saving the time waiting for printing and saving the manual binding operation.
In the process of binding the sheets of paper P by the binding device 15, the second paper feeding roller set 154 close to the binding cassette 152 must have a moving function, and when the two rollers in the second paper feeding roller set 154 are separated, a space is formed for the sheets of paper P to pass through and the binding operation can be performed. After the stapling operation is completed, the two rollers in the second feeding roller set 154 near the stapling cassette 152 move to clamp the sheets P, so as to feed the sheets P away from the stapling device 15.

The first roller set 281 is connected to the paper discharging control module 29, and the second roller set 282 is located at one side of the first roller set 281 and connected to the paper discharging control module 29. The first gear set 283 is connected to the first roller set 281 and the second roller set 282, and is capable of driving the first roller set 281 and the second roller set 282 to rotate respectively. The first power element 284 is coupled to the first gear set 283 and functions to provide a first power to the first gear set 283 when driven.

According to the movement of the first connection portion 291 and the second connection portion 292, the first roller set 281 and the second roller set 282 are driven to move respectively, so that the state of the paper discharging roller module 28 can be changed.
Referring to fig. 3, fig. 4, and fig. 5, fig. 5 is a schematic structural diagram of a paper discharge control module of a printing apparatus according to another view angle in a preferred embodiment of the invention. The switching gear 294 is connected to the switching member 293 in an engaging manner, and is rotatable to drive the switching member 293 to move relative to the paper placing plate 27. The second gear set 295 is meshed with the shift gear 294, which drives the shift gear 294 to rotate. The second power element 296 is connected to the second gear set 295, which may be configured to provide a second power to the second gear set 295 and the switching gear 294 when driven, such that the switching gear 294 moves the switching element 293 relative to the paper placing plate 27. In the preferred embodiment, the first power element 284 and the second power element 296 are motors, which are used for illustration only and not limitation.
The switching element 293 includes a main body 2931, a first extension piece 2932, and two extension pieces 2933. The body 2931 has a saw tooth bar 2931A that is engageable with the switching gear 294 so that the switching element 293 is movable relative to the paper placing plate 27. The first extension piece 2932 is disposed on the first end of the body 2931 and is located on the first side of the body 2931, wherein the first extension piece 2932 has a first protrusion 2932A, which extends into the first sliding slot 2911 and is movable in the first sliding slot 2911. The second extension piece 2933 is disposed on the first end of the body 2931 and is located on the second side of the body 2931, wherein the second extension piece 2933 has a second protrusion 2933A that protrudes into the second sliding slot 2921 and is movable in the second sliding slot 2921. When the switching element 293 moves relative to the paper placing plate 27, the first protrusion 2932A abuts against the inner wall of the first sliding groove 2911 to drive the first connection portion 291 to move. On the other hand, the second protrusion 2933A abuts against the inner wall of the second sliding groove 2921, so as to drive the second connecting portion 292 to move.
During the movement of the switching element 293, when the first boss 2932A is moved to the first position P1 of the first chute 2911 and the second boss 2933A is moved to the third position P3 of the second chute 2921, the paper discharge roller module 28 is in a released state, and the first roller set 281 is away from the second roller set 282, as shown in fig. 3. When the first boss 2932A is moved to the second position P2 of the first chute 2911 and the second boss 2933A is moved to the fourth position P4 of the second chute 2921, the paper discharge roller module 28 is in a paper discharge state, and the first roller set 281 is close to the second roller set 282, as shown in fig. 6.
In order to ensure the normal operation of the paper discharging roller module 28, the printing apparatus 2 of the present invention further includes a position sensing module 20, which is close to the switching element 293, and which is configured to detect the position of the switching element 293 and calculate the moving speed of the switching element 293, so as to determine whether the paper discharging control module 28 is operating normally. The position sensing module 20 detects the position of the switching element 293 to determine, so the switching element 293 further includes a third extension piece 2934 disposed on the second end of the body 291 and close to the position sensing module 20.
On the other hand, the position sensing module 20 includes a light emitting element 201, a sensing element 202, and a control unit 203. The light-emitting element 201 is positioned proximate to the third extension piece 2934 and on a first side of the third extension piece 2934 and functions to generate a light beam. The sensing element 202 is close to the third extension piece 2934 and is located on the second side of the third extension piece 2934, and functions to output a corresponding signal according to whether the light beam is received. When the discharge roller module 28 is in the released state or the discharge state, the sensing element 202 may receive the light beam, that is, the third extension piece 2934 is moved to a position away from the position sensing module 20. When the discharge roller module 28 is in the switching state (i.e. changed to the release state or the process between the discharge states), the third extension piece 2934 shields the light beam, so that the sensing element 202 cannot receive the light beam.
The control unit 203 is connected to the sensing element 202, and has a function of determining whether the paper discharge control module 28 is operating normally or not according to the received first control signal and the second control signal, wherein the control unit 203 can know the time when the sensing element 202 cannot receive the light beam, and thus can calculate the moving speed of the switching element 293. In the preferred embodiment, the light emitting device 201 is a light emitting diode, the sensing device 202 is a light receiver, and the control unit 203 is a microprocessor.
Next, the operation of the printing apparatus 2 of the present invention will be described. When the printing apparatus 2 is driven, the paper discharge control module 29 operates: the second power element 296 drives the second gear set 295 to rotate and drive the shift gear 294 to rotate. The switching gear 294 drives the switching element 293 to move relative to the paper placing plate 27 through the sawtooth bar 2931A. In the moving process of the switching element 293, the first protrusion 2932A abuts against the inner wall of the first sliding groove 2911 to move to the first position P1, so as to drive the first connection portion 291 to move, and the second protrusion 2933A abuts against the inner wall of the second sliding groove 2921 to move to the third position P3, so as to drive the second connection portion 292 to move. The first roller set 281 is far away from the second roller set 282, so that the paper discharging roller module 28 is in a released state. This ensures that the discharge roller module 28 is in a released state.
On the other hand, the plurality of sheet feed rollers 23 near the sheet feed cassette 21 send the sheet P on the sheet feed cassette 21 into the sheet feed path 22, and the sheet P is fed to a position near the printing module 24 by the operation of the plurality of sheet feed rollers 23. When the sheet P passes through the printing module 24, the printing module 24 performs a printing operation on the sheet P. Next, the paper P continues to travel in the paper feed path 22 and is fed to the paper placing plate 27 by the plurality of paper feed rollers 23. At this time, the paper discharging roller module 28 is in a released state, the plurality of paper feeding rollers 23 can feed a plurality of sheets of paper P, such that a first end of the plurality of sheets of paper P passes through the first roller set 281 and the second roller set 282 and is close to the finishing module 25, and a second end of the plurality of sheets of paper P is located on the paper placing plate 27.
Next, the finishing module 25 performs a finishing operation on the plurality of sheets P, and the binding module 30 performs a binding operation on the plurality of sheets P that are finished. After the sheets P are bound, the sheet discharging control module 29 controls the sheet discharging roller module 28 to change to the sheet discharging state, and the operation thereof is as follows: the second power element 296 drives the second gear set 295 to rotate and drive the shift gear 294 to rotate. The switching gear 294 drives the switching element 293 to move relative to the paper placing plate 27 through the sawtooth bar 2931A. In the moving process of the switching element 293, the first protrusion 2932A abuts against the inner wall of the first sliding groove 2911 to move to the second position P2, so as to drive the first connection portion 291 to move, and the second protrusion 2933A abuts against the inner wall of the second sliding groove 2921 to move to the fourth position P4, so as to drive the second connection portion 292 to move. When the first post 2932A is moved to the second position P2 and the second post 2933A is moved to the fourth position P4, the first and second extending pieces 2932 and 2933 are respectively abutted by the first and second posts 2932A and 2933A without moving relative to the paper placing plate 27. In short, the first extension piece 2932 and the second extension piece 2933 can be locked by the mechanism member without moving, and therefore, the paper discharge control module 29 of the present invention can be locked without using a stronger power element.
Thus, the first roller set 281 is close to the second roller set 282, so that the paper discharging roller module 28 is in a paper discharging state. The multiple sheets P are located between the first roller set 281 and the second roller set 282. That is, the first roller set 281 and the second roller set 282 clamp the sheets P, and the paper discharging roller module 28 operates to make the first roller set 281 and the second roller set 282 feed the sheets P from the paper placing plate 27 to the paper discharging tray 26. The above is the operation of the printing apparatus 2 of the present invention.
It should be noted that the printing apparatus of the present invention is not limited to the printing apparatus having the binding module therein, but is not limited thereto.
According to the above-mentioned disclosure, the printing device and the paper discharging control module of the present invention can utilize the paper discharging control module to change the state of the paper discharging roller module, so as to control the positions of the first roller set and the second roller set, so as to ensure that the first roller set and the second roller set are controlled to clamp the paper when the paper is required to be fed. Or when the paper needs to pass through, a gap is formed between the first roller set and the second roller set so as to allow the paper to pass through. Therefore, the printing device and the paper discharge control module can change the positions of the first roller group and the second roller group through a simple mechanical structure, so as to solve the problem that the prior printing device is easy to cause paper feed failure. When the paper discharging control module is in a paper feeding state, the first extension piece and the second extension piece can be locked and not moved, and a powerful power element is not needed as in the prior art.
The above description is for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention as claimed, and all other equivalent changes and modifications that may be made without departing from the spirit of the invention disclosed herein are intended to be included in the claims of the present invention.
