The entrance port 110 is formed to have a width (and / or length) less than the width (and / or length) of the paper medium 10, the paper medium 10 placed on top of the entrance port 110 is provided at the top Pressurized by the pressurizing cam member 200 may be entered into the receiving portion 100 through the entrance port (110). The size and shape of the accommodating part 100 may be variously changed according to required conditions and design specifications, and the size and shape of the entrance opening 110 may also be variously changed according to the type of paper medium used.

In addition, the paper medium 10 placed on the entry port 110 may be provided in a sheet unit as well as a stack unit. Preferably, the paper medium may be provided in units of stacks so as to improve the loading speed of the paper medium and to shorten the time required for depositing.

The pressurizing cam member 200 is provided to be eccentrically rotated so as to be adjacent to the upper portion of the entrance port 110, and presses the paper medium 10 placed on the upper portion of the entrance port 110 according to a loading signal and presses the paper medium 10. ) Can be entered into the receiving portion 100 through the entry port (110). The pressure cam member 200 may be formed to have various shapes and structures according to the required conditions and design specifications. For example, the pressurizing cam member may be formed in various shapes such as a triangular cam or a heart cam, and may be formed in any shape other than eccentric rotation.

The loading table 400 may be elevated in a plate shape having a loading surface on the upper side and reciprocating in the up and down direction selectively in the interior of the accommodating part 100. The paper medium entered through the entry port 110 may be loaded. The stack 400 may be sequentially loaded on the upper stacking surface of the table 400.

In addition, the mounting table 400 is configured such that the pressure cam member 200 descends a predetermined section while pressing the paper medium placed on the entrance port 110. That is, the pressing cam member 200 is rotated to press the paper medium and at the same time the mounting table 400 is lowered to allow a predetermined free space to be provided on the upper surface. Preferably, the free space may be provided at a height such that no interference occurs between the mounting table 400 and the paper medium 10 when the paper medium is pressed by the pressure cam member 200.

Such a structure allows the paper medium to be pressurized by the pressurizing cam member 200 and to secure a free space in the upper portion of the mounting table 400 when the paper medium is pressed into the accommodating part 100. It can be easily implemented.

On the other hand, the driving method of the above-mentioned pressure cam member 200 and the mounting table 400 may be variously changed according to the required conditions and design specifications. For example, the pressurizing cam member 200 and the mounting table 400 may be driven independently by different driving sources, or may be connected to each other to be linked with one driving source. Hereinafter, the pressure cam member 200 and the mounting table 400 will be described with an example configured to be connected to each other so as to be driven simultaneously by one driving source.

That is, the pressure cam member 200 and the mounting table 400 can be connected to each other by the drive unit 300, the drive unit 300 is the input shaft 310, the lead screw 350 and the power transmission Means 320 may be configured.

One end of the input shaft 310 is connected to the drive motor (M) and the other end is connected to the pressure cam member 200 to allow the pressure cam member 200 to be rotated by the driving force of the drive motor.

The lead screw 350 is disposed along the lifting direction of the mounting table 400 to be orthogonal to the input shaft 310, the mounting table 400 is coupled to one side of the lead screw 350 to rotate the lead screw 350. Can be lifted.

The power transmission means 320 is provided to connect the input shaft 310 and the lead screw 350 and to transfer the driving force of the input shaft 310 to the lead screw 350. The power transmission means 320 may be configured in various ways and structures according to the required conditions and design specifications.

For example, the power transmission unit 320 is coupled to the input shaft 310, the first bevel gear 330 and the first bevel gear 330 to be integrally coupled to the second screw is integrally coupled to the lead screw 350 It may be configured to include a bevel gear (340). Therefore, when the input shaft 310 is rotated by the driving force of the driving motor, the lead screw 350 is rotated by receiving the driving force of the input shaft 310 through the first bevel gear 330 and the second bevel gear 340. Can be. In the above-described and illustrated embodiments of the present invention, a conventional bevel gear used for power transmission is described as an example of the power transmission means 320. However, in some cases, the bevel gear is used. Instead, the driving force of the input shaft 310 may be transmitted to the lead screw 350 through a combination of a conventional pinion gear and a rack gear, a combination of other gears, or a combination of belts.

On the other hand, the receiving unit 100 may be provided with a sensing means for determining whether the loading amount of the paper medium to be loaded on the mounting table 400 is less than the predetermined reference value, and based on the result determined by the sensing means Accordingly, the control unit 500 for controlling the driving of the pressure cam member 200 and the mounting table 400 may be provided. In addition, as the sensing means, a conventional optical sensor including a light emitting unit and a light receiving unit may be used, and other sensors may be used in some cases.

The structure and manner of the sensing means can be variously changed according to the required conditions and design specifications. For example, the sensing means may include a first sensor S1 disposed at an uppermost position of the mounting table 400 and a second sensor disposed at a lowermost position of the mounting table 400 so as to be spaced downward from the first sensor S1. S2), and the controller 500 drives the pressurizing cam member 200 and the mounting table 400 according to the signals detected by the first sensor S1 and the second sensor S2. Can be controlled. In addition, an optical sensor including a light emitting unit and a light receiving unit may be used as the first sensor S1 and the second sensor S2 as described above.

In the embodiment of the present invention has been described with an example configured to determine the loading amount of the paper medium through the two sensors, three or more sensors may be used in some cases. Of course, it may be configured to determine the loading amount of the paper medium through a single sensor, it is preferable to be configured to detect the loading amount of the paper medium through a plurality of sensors to improve the stability and reliability.

As described above, the control unit 500 determines the loading amount of the paper medium according to whether the detection signal is generated by the first sensor S1 and the second sensor S2, and thus the pressure cam member 200 and the mounting table 400 may be used. Drive can be controlled.

Here, the detection signal is generated by the first sensor S1 or the second sensor S2 (ON) in the sensing medium of the first sensor S1 or the second sensor S2. 400) is located. That is, in this state, as the signal emitted from the light emitting part of the first sensor S1 or the second sensor S2 is blocked by the paper medium or the mounting table 400, the first sensor S1 or the second sensor ( When the light receiving unit signal of S2 is finally recognized as dark and the light receiving unit signal of the first sensor S1 or the second sensor S2 is recognized as dark, the first sensor S1 or It is determined that the detection signal is generated in the second sensor S2.

On the contrary, the detection signal is not generated in the first sensor S1 or the second sensor S2 (OFF) when the paper medium or the paper is loaded on the sensing line of the first sensor S1 or the second sensor S2. It means that the stand 400 is not located. That is, in this state, the signal emitted from the light emitting unit of the first sensor S1 or the second sensor S2 is input to the light receiving unit of the first sensor S1 or the second sensor S2, and finally the first sensor S1 When the light receiving unit signal of the S1 or the second sensor S2 is recognized as a light and the light receiving unit signal of the first sensor S1 or the second sensor S2 is recognized as the light, the first signal is received. It is determined that the detection signal is not generated in the sensor S1 or the second sensor S2.

Therefore, when the detection signal is simultaneously generated by the first sensor S1 and the second sensor S2 (see FIG. 4), the controller 500 determines that the loading amount of the paper medium reaches a preset reference value and pressurizes it. The driving of the cam member 200 and the mounting table 400 may be stopped. On the contrary, when the detection signal is not generated at the same time from the first sensor S1 and the second sensor S2 (see FIG. 5), and the first sensor S1 and the second sensor S2 (see FIG. 5). When the detection signal is generated only in S1) (see FIG. 6), it is determined that the loading amount of the paper medium is lower than the reference value, and the additional loading of the paper medium is performed by driving the pressure cam member 200 and the loading table 400 normally. Let it go.

In addition, the controller 500 generates a detection signal from the second sensor S2 after the loading of the paper medium on the mounting table 400 according to the loading signal, and the detection signal from the first sensor S1. If not generated (see FIG. 7), the loading table 400 may be raised for a predetermined period before the next paper medium is loaded according to the next loading signal.

That is, such a structure makes it possible to compensate that the loading table 400 is abnormally lowered when the paper medium is loaded in a unit smaller than the predetermined stack unit of the paper medium even though the loading amount of the paper medium is lower than the reference value. . For example, in a state in which the stack 400 is set to descend as much as the stack of paper media composed of five sheets, the stack of paper media stack consisting of smaller than five sheets is repeated. Is abnormally lowered compared to the paper medium loading amount. (See FIG. 7) As described above, a detection signal is generated by the second sensor S2 corresponding to a state in which the loading table 400 is abnormally lowered compared to the paper medium loading amount. When the detection signal is not generated by the first sensor S1, the loading table 400 may be raised for a predetermined period before loading the next paper medium according to the next loading signal. Preferably, the mounting table 400 may be raised to a point at which the detection signal is generated (a point at which the detection signal is generated in the first sensor S1) at the uppermost position of the mounting table 400.

Hereinafter, a method of operating the paper medium storage device according to the present invention will be described. In addition, the same or equivalent reference numerals are given to the same or equivalent components as those described above, and detailed description thereof will be omitted.

3 is a block diagram illustrating a method of operating a paper medium storage device according to the present invention, and FIGS. 4 to 7 are views for explaining a method of operating the paper medium storage device according to the present invention.

As shown in these drawings, the operation method of the paper medium storage device according to the present invention using the pressure cam member 200 to press the paper medium placed on the entrance 110 to the inside of the receiving portion 100 ( S10), pressing the paper medium and simultaneously lowering the loading table 400 to provide a free space on an upper surface of the loading surface 400 (S20), the paper on the lower loading table 400 Loading the medium (S30).

First, the accommodating part 100 having an entry port 110 in the upper portion, the pressurization for providing the eccentric rotation to the upper portion of the entry port 110 to press the paper medium placed on the entry opening 110 to the inside of the accommodating portion 100. It is provided with a cam member 200, the paper medium supply device which is provided to be elevated in the receiving portion 100 and includes a mounting table 400 is loaded with the paper medium entered through the entry port 110.

Next, a paper medium in a sheet or stack unit is placed on the entrance port 110 of the accommodating part 100 according to the loading signal.

Next, the pressurizing cam member 200 presses the paper medium placed on the entrance port 110 to the inside of the receiving part 100. In this step (S10) as the pressurizing cam member 200 is disposed to be eccentrically rotated on the entry port 110, the paper medium is pressed and may enter the receiving portion (100).

Next, while pressing the paper medium as described above, the mounting table 400 is lowered to provide a free space on the upper surface of the mounting table 400. (See FIG. 2) That is, in this step (S20) As the pressure cam member 200 rotates and presses the paper medium, the loading table 400 descends and a predetermined free space may be provided on the loading surface. Preferably, the free space may be provided at a height such that no interference occurs between the mounting table 400 and the paper medium when the paper medium is pressed by the pressure cam member 200.

Thereafter, the paper medium entered into the receiving portion 100 through the pressure cam member 200 may be loaded on the loading table 400 lowered for a certain period. In this manner, the paper medium is pressurized by the pressure cam member 200, and when the paper medium is entered into the receiving part 100, the free space can be secured on the upper portion of the mounting table 400, and the paper medium can be loaded and loaded. It can be easily implemented.

In addition, using the pressure cam member 200 to press the paper medium placed on the entry port 110 on the inside of the receiving portion 100 (S10), and press the paper medium and at the same time the mounting table 400 In step (S20) of lowering the mounting table 400 to provide a free space on the upper surface of the loading, the pressurizing cam member 200 and the mounting table 400 is preferably configured to be linked by the same drive source. In some cases, the pressure cam member 200 and the mounting table 400 may be configured to be driven independently by different driving sources in the above-described steps.

After the completion of the loading of the paper medium on the mounting table 400 according to the requested loading signal as described above, it is possible to determine whether the paper medium loading amount is less than the preset reference value, and according to the determined result 200) and whether the mounting table 400 is driven. That is, when it is determined that the paper medium load is insufficient, when the load is low, the pressurizing cam member 200 and the loading table 400 are normally driven, and additional loading of the paper medium can be performed, and the loading amount of the paper medium is set in advance. When the reference value is reached, the driving of the pressure cam member 200 and the mounting table 400 may be stopped.

In addition, in the step of determining whether the loading amount of the paper medium is less than the reference value, the method of determining whether the paper medium loading amount is less than may be implemented in various ways according to the required conditions and design specifications. As an example, whether or not the paper medium load is insufficient may be determined through conventional sensing means such as an optical sensor. That is, the uppermost position of the mounting table 400 through the first sensor S1 disposed at the uppermost position of the mounting table 400 and the second sensor S2 disposed at the lowermost position of the mounting table 400 and By detecting the presence of the detection signal in the lowest position it can be determined whether the paper medium is not loaded.

As described above, it is possible to control the driving of the pressurizing cam member 200 and the mounting table 400 by determining the loading amount of the paper medium according to whether the detection signals from the first sensor S1 and the second sensor S2 are generated. . At this time, the detection signal is generated (ON) in the first sensor (S1) or the second sensor (S2) on the sensing line of the first sensor (S1) or the second sensor (S2) or the paper carrier It means that 400 is located. On the contrary, when the detection signal is not generated in the first sensor S1 or the second sensor S2 (OFF), the paper medium or the sensing medium of the first sensor S1 or the second sensor S2 is turned off. This means that the mounting table 400 is not located.

Therefore, when the detection signal is simultaneously generated by the first sensor S1 and the second sensor S2 (see FIG. 4), the controller 500 determines that the loading amount of the paper medium reaches a preset reference value and pressurizes it. The driving of the cam member 200 and the mounting table 400 may be stopped. On the contrary, when the detection signal is not generated at the same time from the first sensor S1 and the second sensor S2 (see FIG. 5), and the first sensor S1 and the second sensor S2 (see FIG. 5). When the detection signal is generated only in S1) (see FIG. 6), it is determined that the loading amount of the paper medium is lower than the reference value, and the additional loading of the paper medium is performed by driving the pressure cam member 200 and the loading table 400 normally. Let it go.

In addition, after the stacking of the paper medium on the mounting table 400 according to the loading signal, the detection signal is generated in the second sensor (S2), the detection signal is not generated in the first sensor (S1) (Fig. 7), the loading table 400 may be raised for a predetermined period before loading the next paper medium according to the next loading signal.

That is, in this manner, when the paper medium is loaded in a unit smaller than a predetermined stack unit of the paper medium, the loading table 400 may be compensated for being abnormally lowered even though the loading amount of the paper medium is lower than the reference value. . For example, in a state in which the stack 400 is set to descend as much as the stack of paper media composed of five sheets, the stack of paper media stack consisting of smaller than five sheets is repeated. Is abnormally lowered compared to the paper medium loading amount. (See FIG. 7) As described above, a detection signal is generated by the second sensor S2 corresponding to a state in which the loading table 400 is abnormally lowered compared to the paper medium loading amount. When the detection signal is not generated by the first sensor S1, the loading table 400 may be raised for a predetermined period before loading the next paper medium according to the next loading signal. Preferably, the mounting table 400 may be raised to a point at which the detection signal is generated (a point at which the detection signal is generated in the first sensor S1) at the uppermost position of the mounting table 400.
