As shown in fig. 3, before the sheet processing apparatus 1 of the present embodiment is operated, the platen protrusion 1220 of the platen lever body 122 is located at the home position P1. As shown in fig. 4, when the solenoid valve body 1231 is in the energized state, the solenoid valve body 1231 drives the solenoid push rod 1232 to move toward the first direction D1, that is, to move toward the paper placing platform 100, and the solenoid push rod 1232 simultaneously compresses the spring 1233 toward the first direction D1 and drives the link 1241 to swing about the positioning shaft PA of the supporting frame 121 as the fulcrum, that is, the link 1241 is driven to perform a motion manner such as a seesaw, so that the first rod portion R1 of the link 1241 moves toward the first direction D1, the second rod portion R2 of the link 1241 moves toward the second direction D2 opposite to the first direction D1, that is, moves away from the paper placing platform 100, when the second rod portion R2 of the link 1241 moves toward the second direction D2, the second rod portion R2 simultaneously stretches the spring link 2 to generate an elastic restoring force for the spring link 2 to drive the paper pressing rod 124122 to move toward the second direction D2 through the elasticity of the spring link 1242, and the paper pressing projection 1220 is moved in a direction to approach the paper placing table 100. It should be noted that, in order to clearly express the linkage relationship of the elements of the paper pressing device 12, no paper is placed on the paper placing platform 100 in fig. 4, and therefore the paper pressing protrusion 1220 of the paper pressing rod 122 is directly contacted with the paper placing platform 100 at last, but actually, when a plurality of paper sheets are placed on the paper placing platform 100, the paper pressing protrusion 1220 of the paper pressing rod 122 moves to a position where it is contacted with the paper sheets (as shown in the target position P2 in fig. 2).
As shown in fig. 3, when the solenoid valve body 1231 is switched to the non-energized state when the energized state is changed, at this time, the originally compressed spring 1233 is released, the elastic restoring force generated after the release of the spring 1233 drives the electromagnetic push rod 1232 to move toward the second direction D2, that is, to move away from the paper placing platform 100, and the electromagnetic push rod 1232 drives the connecting rod 1241 to swing with the positioning shaft PA of the supporting frame 121 as a fulcrum, so that the first rod portion R1 of the connecting rod 1241 moves toward the second direction D2, the second rod portion R2 of the connecting rod 1241 moves toward the first direction D1, and when the second rod portion R2 of the connecting rod 1241 moves toward the first direction D1, the second rod portion R2 drives the spring connecting rod 1242 to move toward the first direction D1, and the spring connecting rod 1242 drives the paper pressing rod 122 to move toward the first direction D1 and return the paper pressing protrusion 1220 to the initial position P1.

The sensor 126 is disposed on the supporting frame 121 and located at one side of the platen 122. When the paper pressing protrusion 1220 moves from the start position P1 to the target position P2 to contact the paper P and the stacking height H of the paper P is less than the predetermined height, the shielding piece 1222 of the paper pressing rod 122 is located within the sensing range of the sensor 126, and the paper P is transported to the binding device 13 on one side of the paper platform 100 by a transport mechanism (not shown) on the paper platform 100 for binding. When the platen protrusion 1220 moves from the start position P1 to the target position P2 to contact the sheets P and the stacking height H of the sheets P is greater than the preset height, the mask 1222 of the platen body 122 is not located within the sensing range of the sensor 126 (similar to the relative position between the mask 1222 and the sensor 126 shown in fig. 2), and at this time, the sheets P are transported to the outside by a transport mechanism (not shown) located on the sheet placement platform 100 without performing a sheet binding operation. In the present embodiment, the sensor 126 is, for example, an infrared sensor, but the invention is not limited to the type of the sensor 126, and the type of the sensor 126 can be changed according to the actual requirement. The infrared sensor includes a sensing signal emitter 1261 and a sensing signal receiver 1262 opposite to each other, and the sensing range is defined between the sensing signal emitter 1261 and the sensing signal receiver 1262.
In summary, the keyboard device according to the embodiment of the invention flattens the paper on the paper platform by the paper pressing device and senses the stacking height of the paper, and the paper pressing device mainly comprises the paper pressing rod, the driving component and the linkage component, and the driving component and the linkage component drive the paper pressing rod to move linearly up and down, so that the curled paper is not kicked out by the paper pressing rod during the linear movement process, thereby facilitating the subsequent flattening of the paper and sensing the stacking height of the paper, and the paper stacking operation is not affected by the paper pressing rod during the linear movement process.
