Abstract

PURPOSE:To permit paper sheets to be taken out and replenished easily and to secure a sensing a sensing function, by causing an auxiliary lever disposed between a pressing plate of accommodated paper sheets and a main sensing lever to be held in abutment in a direction for opening the pressing plate so that the main lever is restricted not to displace to the outside of a prescribed displacing range. CONSTITUTION:When there are bank notes fully accommodated or there is no bank note accommodated, a door 9 of a container is opened clockwise so that a spring 9 of the door 9 and a pressing plate 1 are released together outwardly to permit bank notes 10A in contact with the pressing plate 1 to be taken out. At the time, a contact pin 3b of an auxiliary lever 3 which is pressed to a projecting member 1a of a pressing plate is released from its checked state so that the auxiliary lever 3 is turned counterclockwise and its turning moment causes a main lever to turn clockwise through the contact pin 3b. However, since the main lever does not displace further because it is checked by a guide frame 7. With the arrangement, the main lever does not displace to the outside of a prescribed displacing range, whereby paper sheets can be take out and replenished easily, the main lever is not deformed or damaged and a sensing function is secured.

3. Detailed description of the invention

[Technical field to which the invention pertains]

The present invention relates to a device for detecting when the amount of stacked storage in a storage for paper sheets, mainly banknotes, has reached a predetermined upper/lower limit value, and in particular, the present invention relates to a device for detecting when the stacked storage amount reaches a predetermined upper/lower limit value in a storage for paper sheets, mainly banknotes. , which will not cause any inconvenience.

[Prior art and its problems]

Conventionally, in a general storage mechanism for mainly banknotes,
When the amount of stacked banknotes stored in the storage reaches a "full" state, the stored banknotes must be taken out. In addition, in the case of 1,000 yen bills, especially when dispensed from the stored 1,000 yen bills as change for 5,000 yen or 10,000 yen bills in a vending machine, they must be replenished when they become ``empty.'' . As mentioned above, in order to take out and replenish stored banknotes in a timely manner, it is necessary to constantly detect whether the stored banknotes are "full" or "empty". Hereinafter, a conventional example will be explained with reference to the drawings. Fifth
The figure is a side sectional view of a banknote discrimination/accommodation processing device incorporating a banknote storage mechanism, where 29 is a 1,000 yen banknote storage section, and 30 is a high-value banknote storage section for 5,000 yen and 10,000 yen banknotes. Reference numeral 28 denotes a banknote discrimination section, and when the authenticity and denomination of the banknote are determined as a result of the discrimination here, the banknote is conveyed to and stored in a storage section corresponding to the denomination. If the banknote is not determined to be a genuine banknote, it is returned to the slot. In FIG. 5, the thousand yen bill storage 29 is formed between the right side of the conveyance guide 15 and the left side of the pressing plate 1. That is, the banknotes LQA are stacked and stored between the two sides, and are pressed by the compression spring 2 provided between the pressing plate 1 and the storage m9. Note that the high-value bill storage section 30 is also mechanically exactly the same. Next, the structure of the storage section and the stacking and storing operation of banknotes will be described with reference to the top view of the storage section shown in FIG. 5 and FIG. 6. The same figure (in aJ, the conveyor pulley, conveyor belt,
The banknotes 10 that have been conveyed by a pressing roller or the like are stopped in a narrow gap between the left side of the conveyance guide 15 and the right side of the driven member 16. The IOA is the banknote already stored, as described above. There is a button 17 on the left side of the banknote 10, and this button 17 is driven back and forth in the left-right direction in the figure by a button cam 14a connected to a drive motor 13. Further, the conveyance guide 15 and the driven member 16 are attached to the storage side plate 12, and the storage side plate 12 is guided by a guide rail (not shown) fixed to the base 11 so as to be able to reciprocate in the left and right directions in the figure. Supported. The pusher cam 1 is inserted into the unmarked guide groove of the driven member 16.
A cam pin 14b that moves together with 4a is fitted. A protruding portion 1a is provided in a portion of the pressing plate I that does not come into contact with the banknotes 10A, and a lever 25, which will be described in detail later, is pressed into contact with the right side of the protruding portion 1a. The above is the explanation of the structure. Next, in the storage operation, the drive motor 13 is started from the state shown in the same figure (al), and the driven member 1 is moved by the cam pin 14b.
6 is moved to the left together with the conveyance guide 15. As a result, the state shown in FIG. 1 (1) is reached, and the banknote 10 is pushed rightward by the pusher 17 and comes into contact with the banknote 10A already stored. From this state, the drive motor 13 further rotates, and the driven member 16 is further moved to the left by the cam pin 14b, and the pusher cam 14 is further rotated.
The buttons 17 are each driven to the right by a. tc+ in the figure shows the resulting state. That is, the conveyance guide 15 and the driven member 16 move to the leftmost side in the figure, and the pusher 17 conversely moves to the rightmost side. Then, both ends of the banknote 10 are pulled out from the gap between the conveyance guide 15 and the driven member 16, and return slightly in the direction of the arrow toward the original state of the banknote 10. Next, the conveyance guide 15
and the driven member 16 move to the right, and the pusher 17 moves to the left to return to the state shown in the figure (al).Up to this point, the transported banknotes 10 are stored in the storage cabinet, and the banknotes 1
It becomes 0Δ. Now, the pressing plate 1 changes from the initial position fa) in the same figure with the storage operation, but eventually returns to its original state. Furthermore, the position of the pressing plate 1 in this initial state will be displaced to the right in the figure, depending on the amount of stored banknotes 10A. Therefore, this displacement can be transmitted to the lever 25 that is in contact with the protruding portion 1a of the pressing plate 1, and can be used to detect the storage amount. FIG. 7 is a side view of a storage amount detection device having the above-mentioned lever 25 as a main component, and corresponds to the outer surface viewed from the same direction as in FIG. 5. 1a is a protrusion that protrudes toward the front of the page at the upper end of the pressing plate 1; 25 is a lever;
The lower end portion 25a is rotatably supported around a rotation shaft (not shown), and at the same time receives a moment counterclockwise by a torsion spring 26, and presses into contact with the protruding portion 1a of the pressing plate l. In the figure, the lever 25 indicated by a solid line indicates when there is a considerable amount of banknotes stored, the lever 25 indicated by a dashed dot line indicates when the stored state is "empty", and the lever 25 indicated by a dashed double dot indicates when the stored banknote is stored as described below. Indicates when to remove or replenish banknotes. Further, 8E and 8F are position sensors for the lower limit and upper limit of the banknote storage amount, respectively. These position sensors 8E, 8F operate according to the position of the lever 25, and are, for example, photoelectric switches or switches. FIG. 8 shows that in FIG. 7, the storage 1 door 9 is pressed against the pressing plate 1 in order to take out and replenish the stored banknotes 10A. The lever 25 is shown tilted clockwise together with the spring 2, and the lever 25 is also rotated clockwise together with the protrusion 1a. FIG. 9 is a perspective view mainly showing the movement of the lever 25 mentioned above. The lever 25, which was initially at the position A shown by the dashed-dotted line, is pushed down in the direction of the arrow shown by the dashed-dotted line and comes to the position B shown by the dashed-dotted line for the purpose of removing the stored banknotes 10^. Next, when the press plate 1 is returned to its original position together with the storage 1 door 9 (not shown) after the work, the lever 25 should normally return to the position A indicated by the dashed-dotted line. . However, due to the play between the end 25a of the lever 25 and the rotating shaft or the deformation of the lever 25 itself, the position shown by the solid line may be incorrectly set. In other words, the position sensors 8E, 8F As mentioned above, in this conventional detection 8, it is necessary to tilt the lever 25, which is the main member, outward greatly for handling, so the lever 25 itself may be deformed or The lever 25 is easily damaged (and the connection between the lever 25 and the pressing plate 1 is easily disconnected, resulting in a malfunction in the detection operation. Note that the banknote 1
0 (see FIG. 6), if the pressing plate 1 moves to the left from the position shown in FIG.
It is isolated from 5 and has nothing to do with it, causing no inconvenience.

[Purpose of the invention]

The purpose of this invention is to solve the problems more than the conventional ones, and to solve the problem of inconvenience in handling when taking out and replenishing stored paper sheets due to the presence of a detection device, and To provide a limit detection device for the stacked storage amount of paper sheets, which does not cause deformation or damage, and also does not cause problems in the important detection function.

[Key points of the invention]

The key point of the present invention to achieve the above object is to interpose another auxiliary lever between the holding plate for the stored paper sheets and the detection lever, and to push the holding plate in the direction of opening. If the detection lever is brought into contact with this auxiliary lever, the auxiliary lever will remain even when the pressing plate is opened to take out or replenish paper sheets, and by extension, the detection lever will also remain. It is based on the idea that it can be done□. In other words, the configuration of the present invention is such that storage is performed at an appropriate location on the side of the contact surface of the pressing plate that does not come into contact with the paper sheets, with a force that is smaller than the pressing force of the pressing plate. The support plate is guided and supported so as to be pressed in the direction in which the press plate is opened and in a direction approximately perpendicular to the press plate, and a portion of the plate is auxiliary to protrude outward from the press plate. A main lever that is guided and supported by the pressing plate side surface of the protruding part of this auxiliary lever so as to be pressed in a direction substantially perpendicular to this surface, and that limits deviation of this main lever from a predetermined displacement range. and a position sensor that can respectively detect the upper and lower limits of displacement of the main lever. Therefore, the action of the present invention is that even when the pressing plate is moved in the opening direction, the auxiliary lever and the main lever are in pressure contact with each other, and the guide member restricts the displacement of the main lever from deviating from the predetermined range. Therefore, it remains within the restricted range. Note that when the pressing plate is moved in the opposite direction to the opening direction, the auxiliary lever and the pressing plate move together, but the auxiliary lever and the main lever are separated, and the main lever is restricted as described above. Remain in range position.

[Embodiments of the invention]

An embodiment of the present invention, which is suitable for a banknote discrimination/accommodation processing apparatus, will be described with reference to FIGS. 1 to 4. 1st
The figure is a perspective view of one embodiment, FIG. 2 is a side view and a plan view, FIG. 3 is a side view showing a banknote handling state, and FIG. 4 is a banknote discrimination/storage processing device to which this embodiment is applied. FIG. The general structure of this embodiment will be described with reference to FIG. 1
Reference numeral 1 denotes a base of the banknote discrimination/accommodation processing device, and the illustrated portion corresponds to the outer surface of the banknote storage section. 3 is an auxiliary lever, one end of which is rotatably supported around a rotation shaft 3a;
In addition, a tear spring 4 is provided to receive a counterclockwise moment. Note that the moment caused by the tear spring 4 of the auxiliary lever 3 is determined to be smaller than the moment caused by the spring 2 acting on the pressing plate 1 described in FIG. 5 or FIG. 6. A contact pin 3b is provided at the other end of this auxiliary lever 3. Reference numeral 5 denotes a main lever, one end of which is rotatably supported around a rotation shaft 5a, and a torsion spring 6 is provided to receive a moment in the counterclockwise direction. Note that the moment caused by the torsion spring 6 is determined to be smaller than the moment of the torsion spring 4. Now, the other end of the main lever 5 has a protruding abutment part 5b, and this abutment part 5b abuts against the contact bottle 3b. A guide frame 7 is attached to the base 11 so as to surround the part of the main lever 5 that comes into contact with the contact part 5b. Prevent movement beyond a predetermined range. The position of the blocked main lever 5 is indicated by the dashed line in the figure. Additionally, there are two photoelectric switch type position sensors 8E. 8F are attached to the base 11 so as to sandwich the main lever 5, respectively. The position sensor 8E detects the "empty" state of stored banknotes, and is activated when the main lever 5 is displaced to the left in the figure to a predetermined position. Further, the position sensor 8F similarly detects the "full" state, and is activated when the main lever 5 is displaced to the right in the figure to a predetermined position. From Figure 2 (side view of al) and the same figure (front view of bl),
The detailed configuration of this embodiment will be supplementarily explained. The positional relationship between the banknote pressing plate 1 and the protrusion 1a that protrudes laterally, and the support lever 3 and the main lever 5, which were not described in FIG. The surface side and the contact pin 3b provided on the auxiliary lever 3 are in pressure contact with each other, and the main lever 5 is positioned in contact with the contact pin 3b at a slight distance from the end of the protrusion 1a. It is. In addition, the one indicated by the dashed line in the figure (al) is the same JR as that in Figure 1, and is the position when the main lever 5 is prevented from rotating beyond its predetermined range by the guide frame l. By the way, the "auxiliary displacement member j" in this invention, the "main displacement member" and the "guide member" respectively correspond to the auxiliary lever 3, the main lever 5, and the guide frame 7 in the above-mentioned embodiment. Therefore, the operation of this embodiment is as follows. In Fig. 3, when the stored banknotes become "full" or "empty", the storage 1 door 9 is opened clockwise. The spring 2 attached to the door 9 and the pressing plate 1 are opened to the outside together, and the banknotes 10A stored in contact with the pressing plate 1 can be taken out. The contact pin 3b of the auxiliary lever 3, which was in pressure contact with the protrusion member 1a, is released from its blocking state, and the auxiliary lever 3 rotates counterclockwise, and this rotation moment causes
Via the contact pin 3b, the main lever 5 is rotated clockwise. However, since this rotation is blocked by the guide frame 7, the displacement does not exceed the state shown in the drawing. Note that the moment applied to the pressing plate due to the pressing force of the spring 2 is larger than the moment due to the torsion spring 4 of the auxiliary lever 3, so the position of the pressing plate 1 is not affected by the moment from the auxiliary lever 3. It is determined only by the amount of banknotes stored. Further, in the above description, the moment due to the tear spring 4 of the auxiliary lever 3 is determined to be larger than the moment due to the torsion spring 6 of the main lever 5, but they may be equal or vice versa. That is, in that case, when the storage 1 door 9 is opened, the main lever 5 will push the auxiliary lever 3 to the left, and its movement will be blocked by the left side wall of the guide frame 7 (see Figure 1). . Furthermore, the auxiliary lever 3 and the main lever 5 are arranged as shown in FIG.
Since the contact bin 3b is arranged on the left side of the contact portion 5b as illustrated in FIG. does not cause any inconvenience. This is because, although the pressing plate 1 and the auxiliary lever 3 move together, they are separated from the main lever 5 and have no relation to each other. Note that detection of the upper and lower limits of the banknote storage amount by the position sensors 8E and 8F is performed in the same manner as in the conventional case. FIG. 4 is a side view of the external appearance when this embodiment is applied to a banknote discrimination/accommodation processing apparatus. 1,000 yen bill storage compartment in the middle 19. A high-value bill storage section 20 is arranged at the lower stage. Of course, the detection device itself may be exactly the same for both the 1,000 yen bill storage section 19 and the large amount bill storage section 2°.

【Effect of the invention】

The key point of this invention is that another auxiliary lever is interposed between the holding plate for the stored paper sheets and the main lever for detection, and the holding plate is brought into contact with the opening direction, and the auxiliary lever is used to detect the paper sheets. If the main lever of the bracket is brought into contact with the main lever of the bracket, and the deviation from the predetermined displacement range of the main lever of the bracket is restricted, even if the pressing plate is opened to take out or replenish paper sheets, the auxiliary lever will remain in place. In addition, the main lever for detection can also be left in place. Therefore, the present invention has the following superior effects compared to the conventional one. (1) Since the main lever does not move beyond a predetermined displacement range, the handling of taking out and replenishing the stored paper sheets does not become inconvenient due to the displacement of the main lever. (2) In relation to the previous item, the main lever itself will not be deformed or damaged, and the essential detection ability will not be malfunctioning at all. (3) The structure is simple and easy to manufacture, and the cost increase is small.
