Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a shutter mechanism applied to a medium processing device such as a passbook printer used in a financial institution.

2. Description of the Related Art In a passbook printer provided in an automatic transaction device used in a financial institution, etc., in order to prevent external influences after inserting a passbook serving as a recording medium from an insertion slot, the printer is usually provided with a printer. A shutter mechanism is provided in the insertion opening, and simplification of the configuration is demanded.

[0003]

2. Description of the Related Art Conventionally, as a printer for printing on a recording medium such as a passbook and a slip, a printer having a transmission type sensor for detecting the presence or absence of a recording medium at an insertion slot is known. In response to a signal from this sensor, the shutter of the insertion slot is opened, and during printing, image reading, and the like after the recording medium is inserted, in order to prevent another passbook or the like from being inserted from the insertion slot. Then, the shutter of the insertion port is closed, and the locked state is established.

[0004]

The above-mentioned transmission type sensor is usually protected by a transparent member such as glass. However, since the transmission type sensor is provided outside the shutter, dust and the like tend to adhere thereto. If the cleaning is not performed periodically, the transparent member may be blocked by dust or the like, causing a malfunction.

On the other hand, the conventional shutter mechanism has a problem that the lock is required to be performed in a state where the shutter is closed and the configuration is complicated.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a shutter mechanism which is not easily affected by dust and the like and can detect a recording medium with high reliability.

Another object of the present invention is to provide a shutter mechanism suitable for simplifying the structure.

Another object of the present invention is to provide a transaction apparatus having such a shutter mechanism.

[0009]

According to the present invention, according to the present invention, a recording medium transport path comprising a pair of plate members opened and closed by a shutter, and the pair of plate members from an opening formed in one of the pair of plate members. A weight-shaped actuator protruding between members, urging means for urging the actuator in a direction protruding between the pair of plate members from the opening, and the urging means for urging the actuator by passing a recording medium And a shutter mechanism provided with a shielding plate that is vertically displaced with the displacement when displaced against the urging force, and an optical sensor that detects the displacement of the shielding plate.

In the configuration of the present invention, when a recording medium such as a passbook passes through the transport path, the conical actuator is displaced by the passage of the recording medium, and accordingly, the shielding plate is displaced in the vertical direction. The vertical displacement of the shielding plate is detected by an optical sensor. Since this optical sensor can be provided inside the apparatus and its optical axis can be set horizontally, dust and the like hardly adhere to the light projecting portion or the light receiving portion of the optical sensor, and a highly reliable recording medium can be used. Detection becomes possible.

[0011]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a transaction apparatus to which the present invention can be applied. The apparatus main body 2 of the apparatus includes an insertion slot 6 for guiding a passbook 4 as a recording medium into a printer provided inside the apparatus main body 2, an insertion slot 8 for a card, a bill payment outlet 10, A bill insertion slot 12, operation buttons 14, and a display panel are provided.

This transaction apparatus is for performing transactions such as depositing and withdrawing transactions, bookkeeping, balance inquiry, and transfer at a bank, for example, without the intervention of bank staff. This type of transaction apparatus is provided with a shutter mechanism so that a recording medium such as a passbook can be inserted when necessary, and that the recording medium is not inserted when unnecessary. For transactions that require bookkeeping, the shutter is opened to allow the insertion of a passbook, and during transactions that do not require bookkeeping, or while a recording medium (passbook) is already being inserted and processed, the shutter is closed and the recording medium is inserted. Prohibits the insertion of.

FIG. 2 shows an internal side view of a main part of the apparatus shown in FIG. A recording medium transport path 22 is provided inside the apparatus at the insertion port 6.
The sensor S, the shutter 24, and the magnetic reader 10 are arranged in this order from the insertion port 6 side along the transport path 22.
4. The image reader 106 and the printer 107 are provided in this order.

When the customer inserts the passbook in the direction of the arrow through the insertion slot 6, the passbook is transported in the transport path 22 by rollers (not shown), and the account number and the like recorded on the magnetic stripe of the passbook are read by the magnetic reader 104. . As a result, after the validity of the passbook is confirmed, pages and printable lines are further confirmed by the image reader 106, and the printer 1
In step 07, unregistered data sent from a computer (not shown) together with the current transaction data is printed on the passbook.
When printing is completed, the passbook is conveyed in the conveyance path 22 in the reverse direction and is carried out of the insertion slot 6.

FIG. 3 shows an internal side view near the insertion slot. A pair of plate members 18 and 2 are inserted from the insertion port 6 toward the inside of the apparatus.
A recording medium transport path 22 composed of zeros is formed. In this embodiment, a rotary shutter 24 is provided in the middle of the plate member 20 located on the upper side.

FIG. 3A shows a state where the shutter 24 is closed, and FIG. 3B shows a state where the shutter 24 is opened. The open shutter 24 is at a position where the closed shutter 24 is rotated by 90 degrees. A drive mechanism including an automatic lock function of the shutter 24 will be described later.

When such a rotary shutter 24 is used, the shutter 24 forms a part of the recording medium conveyance path when the shutter 24 is opened, so that the recording medium is not easily jammed in the conveyance path. That is, since the non-rotating shutter is normally driven in a direction perpendicular to the conveyance path, it is necessary to provide an opening for the shutter in the conveyance path, and this opening tends to be clogged with the recording medium. By causing the closed shutter to form a part of the transport path as in the example, the clogging of the recording medium is prevented.

FIG. 4 is a front view near the insertion slot. The configuration and operation of the sensor that detects the passage of the recording medium will be described with reference to FIGS.

An opening 18A is formed on each side of the plate member 18 in the recording medium insertion direction, and a triangular pyramid-shaped actuator 26 projects into the transport path 22 from the opening 18A. The actuator 26 is supported by the plate member 1 by the support member 28.
8, and a leaf spring 30 is provided on the bottom of the plate member 18. The actuator 26 receives the elastic restoring force of the leaf spring 30 via the support member 28, and the actuator 26 is constantly urged upward by this force.

A shielding plate 32 is provided at both ends of the leaf spring 30, and an optical sensor 34 such as a photo interrupter is provided to detect the displacement of the shielding plate 32.

The optical sensor 34 has an optical axis in a direction perpendicular to the paper surface of FIG. 4, and the shielding plate 32 blocks the optical axis of the optical sensor 34 so that the vertical movement of the actuator 26, that is, the passage of the recording medium, is prevented. Is detected.

In this embodiment, a depression 20A is formed in a portion of the plate member 20 corresponding to the top of the actuator 26, and the top of the triangular pyramid-shaped actuator 26 is located in the depression 20A. The reason for this is to increase the displacement of the actuator 26 even when the recording medium whose passage is to be detected is thin, thereby improving the detection capability.

Since such a triangular pyramid-shaped actuator is used, when the passbook is inserted and the passbook comes into contact with the inclined portion of the triangular pyramid, a force is generated that pushes the actuator downward, so that the actuator is moved downward. Falling,
An optical sensor detects this. Further, since a pair of actuators are provided on both sides in the width direction of the insertion slot, even if the passbook is inserted with a slight inclination, it can be detected.

As the shape of the actuator 26, another pyramid or a cone may be adopted instead of the triangular pyramid. The reason why such a conical actuator 26 is used is to easily displace the actuator 26 in the vertical direction as the sheet passes through the transport path 22.

According to the present embodiment, the optical sensor 34 can be provided inside the apparatus, and its optical axis can be set in the horizontal direction. It is difficult for sensor troubles to occur due to the adhesion of water. Therefore, a highly reliable recording medium can be detected.

FIGS. 5 to 8 are a front view, a top view, a rear view, and a side view, respectively, of the shutter mechanism employed in this embodiment.

A frame 36 having a substantially U-shaped cross section
A shutter shaft 38 is rotatably supported at both ends of the shutter shaft 38, and a comb-shaped shutter 24 is fixed to a substantially central portion of the shutter shaft 38. At one end of the shutter shaft 38, a shutter plate 42 that rotates integrally with the shutter 24 is provided.

As in this embodiment, the shutter 24 is formed in a comb-like shape, and when the shutter 24 is in the open state, the uneven portions of the comb-like shape of the shutter 24 are formed in the plate member 20. In addition, the gap between the shutter 24 and the plate member 20 is formed by keeping the surface of the shutter 24 in the open state on the transfer path side and the surface of the plate member 20 on the transfer path on the same plane. The end of the passbook does not get into.

At the upper part of the frame 36, a solenoid 44 is provided as a power source for performing linear motion. Reference numeral 46 denotes a link plate provided to be swingable about a shaft 48 fixed to the frame 36. The link plate 46 has a shaft guide 50 that is curved and opened in a substantially U-shape so as to be concave toward the solenoid 44.

Another link plate 54 is provided on the upper portion of the frame 36 so as to be swingable about a shaft 56. The link plate 54 has a shaft 58 that fits loosely into the shaft guide 50.

Reference numeral 60 denotes a link rod whose both ends are connected to the solenoid 44 and the link plate 46. The link rod 60 converts a linear motion of the solenoid 44 into a swinging motion of the link plate 46.

Reference numeral 62 denotes another link rod whose both ends are connected to the link plate 54 and the shutter plate 42, respectively.
Indicates the swing motion of the link plate 54 by the shutter plate 4.
2 rotation motion.

Next, the opening operation of the shutter will be described with reference to FIG. As shown in (A), when the linear motion of the solenoid 44 is transmitted to the link plate 46 as shown by the arrow A, the link plate 46 rotates in the direction of the arrow B, and accordingly comes to rest. The shaft 58 integral with the link plate 54 is guided in a shaft guide 50 formed on the link plate 46.

When the link plate 46 is further rotated, as shown in FIG.
(B), when the shaft 58 reaches the lower end of the shaft guide 50, the rotational force of the link plate 46 moves the link plate 54 through the shaft guide 50 and the shaft 58 in the clockwise direction in the figure. Act to rotate.

The rotational movement of the link plate 54 is converted into the rotational movement of the shutter plate 42 by a link rod 62 (see, for example, FIG. 5).
4 is opened.

Next, the principle of achieving auto-locking (a function in which the closed shutter cannot be forcibly opened) with the shutter 24 closed will be described with reference to FIG. When a force is applied to force the closed shutter 24 to open, the force acts on the link plate 54 via the link rod 62 as shown by an arrow D (see FIG. 10A). With this force, the link plate 5
4 tries to rotate clockwise in the figure. This force is transmitted to the link plate 46 via the shaft 58 and the shaft guide 50.

The force P applied to the link plate 46 can be divided into a force P2 toward the rotation center of the link plate 46 and a force P1 in a direction perpendicular thereto. The force for rotating the link plate 46 is P1, but as shown in FIG. 10B, the trajectory C1 of the shaft 58 and the trajectory C2 of the shaft guide 50 do not coincide with each other. Generates a drag to crush the shaft 58. For this reason, even if it tries to rotate the link plate 54, the link plate 46 prevents the rotation, and as a result, the link plates 46 and 54 do not rotate, and the auto-lock is achieved. Therefore, the shutter does not open when an external force is applied.

Such an automatic lock is made possible by the fact that the shaft guide 50 which is curved and opened in a substantially U-shape so that the link plate 46 becomes concave toward the power source.
It is because it has.

The above-mentioned sensor is provided at the preceding stage of the above-mentioned shutter. When it is necessary to insert a passbook, when this sensor detects the passbook, the shutter is opened, the passbook is inserted, and the inserted passbook is taken into the apparatus. Thereafter, the shutter is closed, thereby preventing another passbook from being inserted.

In this embodiment, since the power transmission between the solenoid 44 as the power source and the main part of the shutter mechanism is performed only by the link rod 60, the power source and the main part are separated from each other. And the degree of freedom in designing the device is increased. Further, since the opening and closing operation of the shutter and the automatic lock can be performed by one power source, the size of the apparatus can be easily reduced.

As shown in FIG. 8, the shutter plate 42 has a shutter stopper 42 as a protrusion on its outer periphery.
A and 42B, and the frame 36 has a frame stopper 36A along the rotation locus of the shutter stoppers 42A and 42B. According to this configuration, the shutter stoppers 42A and 42B come into contact with the frame stopper 36A, so that the shutter plate 42 and the shutter 2
4 can be restricted. The restricted rotation range is, for example, 90 degrees.

In the embodiment described above, a solenoid that performs a linear motion is employed as a power source for driving the shutter, but the present invention is not limited to this. That is, the drive shaft of a power source that performs a rotary motion such as a motor is directly connected to the link plate 46, thereby
May be swung. Also in this case, the force for opening the shutter 24 from the outside is prevented from being transmitted to the power source, so that the opening operation of the shutter and the automatic locking can be performed by one power source.
