PURPOSE:To prevent such an accident that a customer has his or her hand caught by a drum by providing a shutter lock mechanism and one driving source which drives the shutter lock mechanism and a shutter opening/closing operation mechanism associatively. CONSTITUTION:When a shutter 13 in a closed state is opened, a motor 69 as the driving source is rotated to drive the shutter opening/closing mechanism simultaneously with the shutter lock mechanism. The shutter lock mechanism is driven to disengage a projection part 63 provided to an arm part 40 from an engagement recessed part 72 which holds the shutter 13 closed, so that the shutter beings to be opened. When the shutter reaches a specific opening position, the motor as the driving source stops rotating and the opening operation of the shutter is completed. At this time, the arcuate engagement part 75 of the shutter lock mechanism engages the projection part 63 of the arm part 40a to hold the shutter open and the restraint part of the shutter lock mechanism restrains the rotation of the drum part 1. Consequently, such an accident that the customer has his or her hand caught by the drum part is prevented.

Here, the banknote retrieval operation according to the above-described configuration will be briefly described below.

When the shutter 13 is opened, the customer inserts the banknotes 12 into the banknote pool section 11 all at once. At this time, bill pressure 1
5 is open, the entrance to the double-feed prevention mechanism is blocked by the center guide 29, and even if coins or foreign objects 26 are accidentally thrown in, they will not enter the double-feed prevention mechanism. Each sensor 35a inputs the banknotes 120 into the banknote pool section 11.

35b and 36a, 36b, the shutter 13 is closed and the motor 2 is activated to take in the bill 12.
1 is rotated and link 20. The bill pressure 15 is pressed against the picker roller 14 via the arm 19. As a result, the center guide 29 is drawn toward the picker roller 14 side and becomes parallel to the bill pressure 15, and the banknotes 12 are pressed against the picker roller 14, and as the picker roller 14 rotates, they are separated and fed. The sheets are separated and fed one by one by a double feeding prevention mechanism including 22 and reverse roller 23, sent to a conveyance path 24, and taken into the apparatus.

Next, the structure and opening/closing operation of the shutter 13 will be explained using FIGS. 9 and 10.

Figure 9 is a side view of the main parts showing the structure of the shutter;
1 indicates the shutter closed state, and ('b) indicates the shutter open state. FIG. 10 is a side sectional view of the main part showing the structure of the shutter locking mechanism shown in FIG. It shows.

The shutter 13 is connected to the shutter arm 4 as shown in FIG.
It is rotatably supported by a fulcrum 41 at the lower end of the
A post 42 formed on the upper part of the four fulcrums engages with a motor 44 via a link 43. 45 is a spring hung on this shutter arm 4o,
The shutter 13 is urged in the closing direction.

Therefore, when the motor 44 rotates in the direction of arrow A, the link 43 rotates upward and separates from the post 42, thereby closing the shutter 13 due to the tension of the spring 45, and conversely, the motor 44 rotates in the direction of arrow B. Then link 4
3 rotates downward and comes into contact with the post 42, and the spring 4
The post 42 is pressed against the tension of 5.
The shutter 13 opens. In this way, the shutter 13 is opened and closed by the rotation of the motor 44. In this device, the 9th
It is possible to stop in two positions: the shutter open state as shown in Figure (a), and the shutter closed state as shown in Figure (b).

Next, the lock structure of this shutter 13 will be explained with reference to FIG.

As shown in FIG. 10, the shutter 13 has a solenoid 4.
A shutter lock 48 is provided via a link 47 and a shutter lock 48, and this shutter lock 48 is rotatably supported around a fulcrum 49, and when one end engages with the rear end of the shutter 13, the shutter lock 48 locks the shutter 13. prevents it from opening easily due to external action. A spring 50 is applied to the shutter lock 48, and urges the shutter lock 48 in a clockwise direction in the figure, that is, in a direction in which it engages with the shutter 3.

As a result, when the solenoid 46 is energized and the shutter lock 48 is rotated in the direction of the half-hour hand in the figure against the tension of the spring 50, the shutter lock 48 and the shutter 13 are rotated.
The shutter 13 is now free to rotate, that is, to open and close.

In this way, the shutter lock 48 allows the shutter 13 to be opened and closed by the action of the solenoid 46, and in this device, as shown in FIG. It can be held in two positions: a locked state in which it cannot be opened, and an unlocked state in which the shutter for inserting banknotes is open, as shown in FIG.

51 is a sensor that detects the position of the shutter lock 48 and detects whether the shutter 13 is in the locked state; 52;
detects the position of the arm of the shutter 13 and releases the shutter 13.
This is a sensor that detects the position of the shutter 13, that is, whether or not the shutter 13 is in an open state.

To explain the opening/closing operation of the shutter 13 with the above-described configuration, first, in the opening operation, the solenoid 46 is set to ONL,
The shutter 13 is unlocked by rotating the shutter lock 48 against the tension of the spring 50 and disengaging it from the rear end of the shutter 13. Thereafter, by rotating the motor 44 shown in FIG. 9 in the direction of arrow A, the link 43 is rotated clockwise and the shutter 13 is opened.

Then, a sensor 52 shown in FIG.
0, the position of the shutter 13 is detected, and if the sensor 52 is turned on, that is, if it is detected that the shutter 13 is in the open state, the rotation of the motor 54 is stopped and the shutter 13 is opened. Stop in open state.

On the other hand, in the shutter closing operation, when the insertion of a bill into the bill pool section 11 is detected and shutter closing is instructed, the link 4 is rotated by rotating the motor 54 in the direction of arrow B in the figure.
Post 42 that was pressed by rotating 3 in the direction of the half-hour hand
Separate from. As a result, the shutter 13 rotates around the fulcrum 41 due to the tension of the spring 45 and closes.

At this time, when the solenoid 46 is turned OFF, it is biased by the spring 50 so that it engages with the rear end side when the shutter 13 is in the clockwise direction in the figure, that is, when the shutter 13 is completely closed. When the tip of the shutter 13 hits the stopper 38 and is completely closed, the shutter lock 48 rotates and engages as described above, the shutter 13 is locked, and the shutter closing operation is completed.

The sensor 51 is set to detect when the shutter lock 48 engages with the shutter 13.

[Problem to be solved by the invention]

However, according to the above-mentioned conventional technology, two types of mechanisms are required: an opening/closing mechanism for opening and closing the shutter and a locking mechanism for locking the shutter, which increases costs and requires the implementation of two mechanisms. Therefore, there was a problem in that the device had to be large-sized.

Furthermore, when opening the shutter, the shutter must first be unlocked, and then the shutter must be opened. In conventional technology, each mechanism has a separate drive source (motor) and is driven by each drive source, so the stability of each mechanism is required for the shutter unlocking operation. It was necessary to ensure a predetermined stabilization time by taking into account the time and variations in the operation of each mechanism.

For this reason, the shutter opening/closing operation time becomes longer, and in a main body device equipped with this shutter opening/closing mechanism, there is a problem in that the processing time becomes longer and, as a result, the device operating rate decreases.

In addition, since a stamping motor is used to drive and hold the drum, if the stamping motor loses its holding power due to a power outage or electrical failure, the drum will be able to rotate freely and the customer will be able to use it when the shaft is open. could get caught in the drum and cause injury.

The present invention has been made in order to solve the above-mentioned problems, and prevents the high cost caused by using a plurality of mechanisms to open and close the shutter and the increase in size of the device due to securing the mounting space. The object of the present invention is to shorten the opening/closing time to shorten the processing time of the device, and to provide a small bill retrieval device with high operating rate.

Furthermore, it is an object of the present invention to provide a highly reliable banknote retrieving device that prevents customers from having their hands caught in the drum.

(Means for Solving the Problems) In order to achieve the above-mentioned objects, the present invention has the following features: 1. A rotatable drum section consisting of a banknote pool section through which customers exchange banknotes and a separation mechanism that separates and feeds banknotes into the device one by one, a drive mechanism that rotates the drum section, and arm sections at both ends. A bill retrieval device including a shutter rotatably supported by a fulcrum provided therein, and a shutter opening/closing mechanism that rotates the shutter to open and close the bill pool portion, wherein the shutter is provided on one of the arm portions. a shutter having a protrusion, an engagement recess that engages with the protrusion to keep the shutter in the closed state, and an arcuate engagement part that engages with the protrusion to keep the shutter in the open state. The device includes a lock mechanism and one drive source that interlocks and drives the shutter lock mechanism and the shutter opening/closing mechanism.

Furthermore, in the present invention, the shutter lock mechanism is provided with a regulating part that regulates rotation of the drum part when the shutter is in an open state.

(Function) With the above configuration, when opening the shutter in the closed state, the motor serving as the drive source is rotated to drive the shutter opening/closing mechanism at the same time as the shutter locking mechanism. As the shutter lock mechanism is driven, the engagement recess that holds the shutter in the closed state is disengaged from the protrusion provided on the arm, and the shutter starts to open.

When the shutter reaches a predetermined opening position, the motor serving as the drive source stops rotating, and the shutter opening operation is completed.

At this time, the arcuate engaging portion of the shutter lock mechanism engages with the projection of the arm portion to maintain the open state of the shutter, and the rotation of the drum portion is regulated by the restriction portion of the shutter lock mechanism.

Furthermore, by rotating the motor serving as the drive source in the opposite direction to that described above, the shutter can be shifted from the open state to the closed state.

Further, this lock bracket 70 has a retaining portion 74 at the upper end portion approximately in the center thereof. This retaining portion 74 is connected to the stud 6 as the gear 650 rotates during the opening operation of the shutter 13.
7 and rotates the lock bracket 70 upward about the fulcrum 71 against the tension of the spring 73.

Reference numeral 75 denotes an arcuate recess formed in an arcuate shape substantially at the lower end of the lock bracket 70, and the shutter 13
When in the open position, it engages the stud 63 of the shutter arm 40 to maintain the position of the lock bracket 70 against the tension of the spring 73.

Reference numeral 76 is a regulating portion that engages with a post 80 provided on the flange 3a to regulate rotation of the drum 1 in the direction of arrow J. Further, the post 81 is in contact with the flange 3a and the drum 1
The rotation in the direction of the arrow ■ is restricted.

A sensor 90 detects the open position of the shutter 13 by detecting the shutter arm 40a, and a sensor 91 detects that the shutter 13 is locked by detecting the free end side of the lock bracket 70.

The shutter opening/closing operation of this embodiment with the above configuration will be explained by adding FIGS. 5 and 6 to FIGS. 1 to 4.

FIG. 5 is a time chart when the shutter is closed, and FIG. 6 is a time chart when the shutter is opened.

First, the positional relationship between the link 62, the lock bracket 70, and the gear 65 when the shutter 13 is closed will be shown.

As shown in FIG. 2, the link 62 has its tip connected to the post 42.
and is spaced apart from the lock bracket 7 in a predetermined relationship.
0, the engaging portion 74 at the center is separated from the stand 67 of the gear 65 by a predetermined gap. Furthermore, the engagement recess 72 at the right end in the figure of the lock bracket 70 is connected to the shutter arm 4.
It is configured to reliably engage with the stud 63 of 0,
This locks the shutter 13.

Also, when the shutter 13 is closed, the lock bracket 7
The regulating portion 76 of 0 and the post 80 of the flange 3a do not engage with each other, and are configured to separate with a predetermined gap so as not to interfere when the drum 1 rotates.

When the shutter 13 is opened from the closed state, the position of the drum 1 is set at the transfer position where the customer receives and receives banknotes. Therefore, by rotating the motor 69 in the direction of arrow C shown in FIG. 1, the gear 65 is rotated in the direction of arrow A. The rotation of the gear 65 rotates the link 62 via the stand 66 in the direction of arrow E, that is, downward about the fulcrum 64, as shown in FIG.

As a result of this rotation, the link 62 comes into contact with the post 42 of the shutter arm 40a, which is spaced apart from its tip by a predetermined distance, as shown in FIG.

Further, due to the rotation of the motor 69, the link 62 is moved to the post 42.
to impose. As a result, the shutter 13 moves in the opening direction, and as shown in FIG.
a to a position where it is detected by the sensor 90 (hereinafter referred to as the shutter opening completion position).

The opening operation of the shutter 13 is completed by detecting the shutter opening completion position and stopping the motor 69.

Note that during this opening operation of the shutter 13, the lock bracket 70 unlocks the shutter 13 by the following operation.

From the closed state of the shutter 13 shown in FIG. 2 to the time when the link 62 shown in FIG. The gear 6 is attached to the engaging portion 74.
The studs 67 of 5 abut and engage, and the further motor 6
9 pushes up this engaging portion 74. As a result, the lock bracket 70 rotates about the fulcrum 71 in the direction of arrow F in the figure, that is, upward. This upward rotation causes the stud 63 of the shutter arm 40a, which was engaged when the shutter 13 was closed, to engage with the engagement recess 7.
2 is disengaged, the shutter 7 13 becomes unlocked and can be opened.

That is, as shown in FIG. 3, when the link 62 comes into contact with the post 42, the engagement between the stand 63 and the engagement recess 72 is completely disengaged, and therefore, as shown in the time chart of FIG. When the shutter 13 starts to open due to the action of the link 62, the shutter 13 is unlocked and the opening operation of the shutter 13 is reliably performed.

In this way, as the opening operation of the shutter 13 progresses, the gear 6
5, the stand 67 that rotates the lock bracket 70 upward is disengaged from the engagement portion 74. As a result, the lock bracket 70 attempts to rotate in the direction of arrow G in FIG. The arcuate engaging portion 75 at the bottom of the lock bracket 70 engages to stop the lock bracket 70 from rotating. The arcuate engaging portion 75 is formed concentrically with the engaging stud 63, and the shutter 1
It is designed not to affect the operation of 3.

When the sensor 90 detects that the shutter 13 has reached the shutter open position shown in FIG.
Complete the opening operation.

Further, as the lock bracket 70 rotates around the fulcrum 71 in conjunction with the opening operation of the shutter 13, the regulating portion 76 of the lock bracket 70 and the post 8 of the flange 3a
0 starts to engage, and completely engages in the state shown in FIG. Therefore, when the shutter 13 is in the open state, rotation of the drum 1 in the direction of arrow J can be restricted. Furthermore, regarding the rotation of the drum 1 in the direction of the arrow 1, the frame 5a
This is regulated by the contact between the boss 8 and the flange 3a.

Next, the closing operation of the shutter 13 will be explained.

To close the shutter 13, in the state shown in FIG. 4, the gear 65 is rotated in the direction of arrow B, opposite to the opening operation, and the link 62 is rotated in the direction of arrow H in the figure.

As a result, the force pressing the post 42 at the tip of the link 62 is gradually released. Since the shutter 13 is urged in the closing direction by the spring 45, as the pressing force from the link 62 is released, the spring 45
5 and moves in the closing direction, and starts the closing operation as shown in the time chart of FIG.

When the tip of the shutter 13 comes into contact with the stopper 38 and the shutter 13 is closed to the state shown in FIG. 2, the tip of the link 62 separates from the post 42, contrary to the shutter opening operation described above.

As the shutter 13 closes, the shutter arm 40a
The stud 63 is removed from the arcuate engaging portion 75 of the lock bracket 70. Therefore, the lock bracket 70 rotates in the direction of arrow G in FIG. 3 due to the tension of the spring 73, and when the shaft 13 moves to the state shown in FIG. The shutter is locked.

In this state, the shutter lock is confirmed by detecting the right end, that is, the free end, of the lock bracket 70 by the sensor 91. As a result, the motor 69 that rotates the gear 65 is stopped, and the closing operation of the shutter 13 is completed.

In the above description, a banknote retrieval device is taken as an example, but the present invention is not limited to this, and it is conceivable that the present invention can be broadly applied to a shutter opening/closing mechanism that requires a locking mechanism.

(Effects of the Invention) As explained above, according to the present invention, a shutter lock mechanism is provided that engages with a protrusion provided on the arm of the shutter to maintain the closed and open states of the shutter. The shutter opening/closing mechanism is linked with a single drive source.

Therefore, when opening and closing the shutter, by rotating one motor, which is the drive source, in a predetermined direction, the shutter locking mechanism and the opening/closing mechanism can be driven simultaneously and continuously. The shutter can be locked and released in conjunction with the shutter.

Therefore, in the present invention, there is no need to provide a plurality of drive sources for opening/closing operations and locking operations, and there is also no need for mounting space, so that it is possible to realize low cost and downsize the mechanism.

Furthermore, in the present invention, when the shutter is in the open state, the rotation of the drum section is regulated by the regulating section provided in the shutter lock mechanism, thereby preventing an accident in which a customer's hand gets caught in the drum section, and improving reliability. A banknote retrieval device with high trajectory can be realized.
