Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an automatic transaction device for performing cash transactions, and particularly to a shutter structure of a transaction opening provided on an operation surface.

(Prior Art) A conventional automated teller machine for automatic cash transactions will be described with reference to FIGS. 3 and 4.

FIG. 3 is an external perspective view of an automatic transaction device according to the prior art, and FIG. 4 is a cross-sectional view taken along the line AA in FIG. 3.

In FIG. 3, the customer inserts a magnetic card (not shown) or a magnetic passbook (not shown) into the card insertion slot 1 or passbook insertion slot 2, and presses the input key 4 according to the instructions on the display device 3 attached to the operation surface 8. By inputting the desired transaction type, amount, etc., the cash transaction was carried out through the transaction opening 5. The transaction opening 5 is configured to be closed by a shutter 6 during maintenance operations by maintenance personnel, and a display board 7 is provided on the surface of the shutter 6 to indicate to the customer that the transaction is to be canceled.

In FIG. 4, a deposit/withdrawal machine unit 9, which is one of the functional units, is provided inside the horizontal operation surface 8.
Can move in the direction. As the deposit/withdrawal machine unit 9 moves, the shutter 6 expands and contracts. The shutter 6 has shutter plates 10a, 10b, 10c, and 10d.
Make the ends into a comb shape and round them by curling, etc.
Shafts 11a, 11b, 11c, 11d, 11
It is constructed by connecting with e. Therefore, the shutter plate 10 can freely rotate around each shaft. The shafts 11a and 11c can slide on a frame (not shown) in the direction of arrow B-C.
1e is fixed to the frame. Further, the shafts 11b and 11d are provided with a shutter plate 10a,
A torsion coil spring (not shown) is attached as a biasing member so that 10b, 10c, and 10d expand to close the transaction port 5. The solid line in FIG. 4 shows the relationship between the cash depositing and dispensing machine unit 9 and the shutter 6 during maintenance operations, and the shutter plates 10a, 10b, 10
c and 10d are expanded by the biasing force of a torsion coil spring (not shown) to block the transaction opening 5, and the display board 7 indicates to the customer that the transaction should be cancelled. The two-dot chain line in the figure shows a state in which the maintenance operation has been completed and the deposit/disburse machine unit 9 has been moved in the direction of arrow C and stopped at the set position where transactions from the transaction opening 5 are possible. Deposit/withdrawal machine unit 9
When moving in the direction of arrow C, the left free end of the shutter 6 is pushed against the biasing force of a torsion coil spring (not shown), and the shutter 6 is folded along a frame (not shown).

(Problems to be Solved by the Invention) However, the automatic transaction device is used by a large number of people, and from an ergonomic point of view, it is preferable for the operating section to face the operator as shown in FIG. This is because by having an inclined surface facing the operator, the operator can see the characters on the display device and input keys just by bending his or her head slightly, and because the characters are easier to see, there are fewer malfunctions. Become.

By the way, if the operating surface is tilted, the transaction section of the deposit/withdrawal machine unit must be set in the set position without any gaps with the transaction opening of the operation section. The same slope must be provided for both. On the other hand, the shutter must be parallel to the operating surface. Then, even if the cash depositing and dispensing machine unit is moved in the direction of arrow C, the left free end of the shutter does not come into contact with the cash depositing and dispensing machine unit, and the shutter cannot be folded due to movement of the cash depositing and dispensing machine unit. Therefore, to fold the shutter, touch the left free end of the shutter,
A problem arises in that another drive means is required, in which the force acts parallel to the operating surface.

This invention does not require any other drive means to fold the shutter even if the operating section is tilted.
It is an object of the present invention to provide a mechanism for folding a shutter by moving a depositing and dispensing machine unit, similar to the prior art.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides an automatic transaction device in which the functional unit is provided with an abutting portion at one end on the shutter side, and the shutter is arranged approximately in the direction in which the shutter plate is folded. A pair of parallel crank mechanisms are arranged in parallel and opposite to each other on the inside of the operation surface with the transaction opening in between, and the shutter plate and shaft are shared by each of the pair of parallel crank mechanisms forming a link and shaft close to the transaction opening. One end of the shutter is fixed, a contact plate is provided at the other end, and the contact part of the functional unit is applied by the biasing force of the biasing member provided between the shutter plate and the shaft. This is what they were brought into contact with.

(Operation) Since the present invention is constructed as described above, the abutting portion of the functional unit is brought into contact with the abutting plate at the free end of the shutter, and the functional unit is moved from one side to the other until it is in the set position where transactions are possible. When the functional unit moves to , the contact portion of the functional unit slides along the contact plate of the shutter while resisting the biasing force of the biasing member. Then, while sliding, the force in the moving direction is resolved into a component force in the direction of the inclined surface of the operating surface and a component force in the direction perpendicular to the inclined surface, and the parallel crank mechanism is folded by the component force in the direction of the inclined surface. As a result, the shutter plate forming the link near the transaction opening is also folded. Further, when the functional unit is moved from the set position to one side, the shutter plate expands due to the biasing force of the biasing member, thereby also extending the parallel crank mechanism. Therefore, the automatic transaction device of the present invention can fold the shutter plate by moving the functional unit, eliminating the need for any other driving means.

(Example) An example of the present invention will be described with reference to the drawings.

Note that elements common to each drawing are given the same reference numerals. FIG. 1 is a sectional view of an automatic transaction device according to the present embodiment, in which the operating surface of the conventional example shown in FIG. 4 is an inclined operating surface, and the shutter is replaced with the shutter of the present invention. A transaction port 5 is provided on the operation surface 8a, and a shutter 12 and a deposit/withdrawal machine unit 9 are arranged inside the operation surface 8a. The shutter 12 connects the abutment plate 18 provided at one end to the cash deposit/withdrawal machine unit 9.
The links 14c and 14d at the other end are fixed to a frame (not shown) substantially at right angles to the operation surface 8a. Further, both ends of the shafts 13a and 13c of the shutter 12 are supported by grooves of a frame (not shown), and both ends of the shaft 13a slide in the grooves in the direction of arrow FG. Also, shaft 13
Both ends of b are not supported by the grooves of the frame (not shown) and are in contact with the lower surface of the frame, so when the shutter plates 17a and 17b are expanded, the central part of the shutter 12 moves in the direction of arrow I. I'm feeling a little depressed. FIG. 2 is a perspective view showing the shutter structure of FIG. 1. The shutter 12 has a link 14a,
14b, 14c, 14d, 14e, 14f and shutter plates 17a, 17b and links 15a, 1
5b, 15c, 15d to the shafts 13a, 13
The distances between the shafts on opposite sides of b, 13c, 13d, 13e, and 13f are equal, and each shaft is rotatably connected. Therefore, the shutter 12 has links 14c, 14b, 14c, 15a, 15b.
and a ladder-like parallel crank mechanism 19 formed from shutter plates 17a and 17b, and link 1.
4d, 14e, 14f, 15c, 15d and the ladder-shaped parallel crank mechanism 20 formed from the shutter plates 17a, 17b.
b, 13c, 13d, 13e, and 13f are connected as constituent and shared elements. Further, the link portion on the other end side of the shutter 12 is connected to links 14a, 14.
A contact plate 18 that is brought into contact with the deposit/disburse machine unit between f
is fixed. Further, a torsion coil spring 21 is attached to the center of the shaft 13b, and both ends of the torsion coil spring 21 are connected to the shutter plates 17a,
17b, and is always biased in the directions of arrows D and E.

Next, the action will be explained. Since the parallel crank mechanisms 19 and 20 perform the same operation, the action will be explained based on the movement of the parallel crank mechanism 19.

When the deposit/withdrawal machine unit 9 moves in the direction of arrow C, the roller 22 moves against the contact plate 18 of the shutter 12 while rotating in the direction of arrow J. Also, at this time,
The roller 22 pushes the contact portion of the contact plate 18 with a force K directed in the direction of arrow C, but this force K is decomposed into a component force M directed in the direction of arrow J and a component force L directed in the direction of arrow G. do.

The component forces L and M are expressed by the inclination angle θ of the operation surface 8a as follows.

L=Kcosθ M=Ksinθ Since the inclination angle θ is around 10°, L>M The relationship is as follows.

As a result, component force M in the direction of arrow J is applied to link 14a.
is pushed in the direction of arrow J, but the shaft 13a does not move in the direction of arrow J because it is made to move only in the direction of arrow G-F by a groove in the frame (not shown). Also, the component force L in the direction of arrow G pushes the link 14a in the direction of arrow G, but since the shutter 12 is slightly sunken in the direction of arrow I at the center, the link 14b moves in the direction of arrow I due to the characteristics of the parallel crank mechanism. The link 14a moves in the direction of arrow G while resisting the urging force of the torsion coil spring 21. When the deposit/withdrawal machine unit 9 moves from the transaction opening 5 to the set position where transactions can be made,
The shutter 12 is in the state shown by the two-dot chain line. When maintenance personnel move the deposit/withdrawal machine unit 9 in the direction of arrow B during maintenance operations, the shutter plates 17a,
17b is expanded by the biasing force of the torsion coil spring 21, the link 14b moves in the direction of arrow H, and the link 14a moves in the direction of arrow F. When the deposit/disbursement machine unit 9 reaches the maintenance operation position, the display board 7 at the transaction opening 5 displays a message indicating that the transaction has been canceled.

(Effects of the invention) Since the present invention is configured as described above, it produces the effects described below.

The functional unit is provided with an abutting part, and the shutter plate that folds along the operating surface is equipped with a parallel crank mechanism with an abutting plate on the free end side, so that even if the operating surface is sloped, the functional unit can be easily operated. The shutter plate can be opened and closed by movement, and a force is applied parallel to the operating surface, eliminating the need for a driving means to open and close the shutter plate.

Therefore, it is possible to tilt the operation surface without the need for the above-mentioned drive means and the control unit that controls it, and the characters on the display device and input keys are easy to see, and the automatic transaction is excellent in operability and design. equipment can be provided.
