Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a thickness detecting apparatus,

The present invention relates to a thickness detecting apparatus and a financial instrument using the same.

The medium thickness sensing device is a device for sensing the thickness of a medium to be conveyed to judge whether the medium is true or not. Since the thickness of the medium is constant, it is possible to determine the authenticity by sensing the thickness of the medium.

The prior art includes a light emitting portion, two light receiving portions and a circular thin film, and detects the thickness of the light receiving portion due to the change of the light amount while the thin film moves mechanically when the medium enters.

However, such a conventional technique has a problem that the reliability of the sensor is degraded if the position of the screen is not perpendicular to the center of the light receiving portion.

The present invention provides a thickness detecting apparatus capable of increasing the reliability of the detecting function of detecting the thickness of a medium to be transported.

In one example, the thickness detecting apparatus includes a light emitting sensor unit that emits light, a light emitting unit that emits light emitted from the light emitting sensor unit and is spaced apart from the light emitting sensor unit, And an amount of light transmitted from the light emitting sensor unit to the light receiving sensor unit as it moves together with the detection roller is provided between the light emitting sensor unit and the light receiving sensor unit, And a curtain film member for changing the curtain film member at a predetermined ratio.

According to the present invention, since the thickness of the medium is detected by the rate of change of the amount of light detected by the light receiving sensor section, the reliability of the medium thickness detecting function is enhanced.

According to the present invention, the number of sensors can be reduced as compared with existing sensors, so that the unit price can be lowered and the assembly can be facilitated.

According to the present invention, there is an advantage that the initial position adjustment is not required since the initial value of the sensor module increases proportionally to the entry of the medium regardless of the position.

According to the present invention, there is an advantage that the position of the clipping plate, which is a problem of the related art, does not have to be adjusted to come to the center of the sensor.

According to the present invention, since thickness detection is performed with the ratio of the amount of change of the amount of light, there is an advantage that it is not sensitive to changes in the light emission over time of the sensor.

According to the present invention, there is an advantage of being insensitive to vibration as compared with existing sensors.

Hereinafter, such a thickness detecting apparatus will be described in detail. In the following, it is assumed that the sensing object of the thickness detecting device is the medium. However, this assumption is only for convenience of explanation, and the sensing object of the thickness detecting apparatus according to the present invention is not limited to the medium.

FIG. 2 is a schematic view of a main portion of a thickness detecting apparatus according to an embodiment of the present invention, and FIG. 3 is a sectional view of a thickness detecting apparatus according to an embodiment of the present invention, And the configuration of the member is enlarged and simplified from the side.

2 to 3, the thickness detecting apparatus according to the present invention is a thickness detecting apparatus including a detecting roller 100 whose position is moved as the medium M passes through, A light receiving sensor unit 230 for sensing the light emitted from the light emitting sensor unit 210 and a light receiving sensor unit 230 for receiving the light emitting sensor unit 210 and the light receiving sensor unit 230, And the amount of light transmitted from the light emitting sensor unit 210 to the light receiving sensor unit 230 changes as the detection roller 100 moves along with the detection roller 100, Member (110).

The thickness detecting apparatus of the present invention includes a frame 1 and a support roller 300 rotatably installed on the frame 1 to support the medium M and facilitate the conveyance of the medium M do.

The detection roller 100 forms a roller portion 101 at a lower portion and a support 103 at an upper portion of the roller portion 101. The roller portion 101 is inclined at a predetermined angle from the support 103, To the frame (1).

The detection roller 100 is moved upward by the roller unit 101 due to the thickness of the measurement object medium M that is in close contact with the upper side of the support roller 300 and is transported to the upper side of the support roller 300, The curtain wall member 110 is moved in the advancing direction or advancing direction of the medium M in proportion to the length of the support base 103 with respect to the rotation axis 105 as the roller unit 101 moves upward, Direction.

At this time, the end of the support 103 moves in proportion to the thickness of the medium M.

The curtain wall member 110 is installed at an end of the supporting frame 103 so that the curtain wall member 110 moves as the supporting frame 103 moves.

As shown in FIG. 3, the skin member 110 is positioned between the light-emitting sensor unit 210 and the light-receiving sensor unit 230 so as to be spaced apart from each other.

As the curtain wall member 110 moves, the amount of light emitted from the light emitting sensor unit 210 is detected by the light receiving sensor unit 230 at a constant rate.

That is, the curtain wall member 110 located between the light emitting sensor part 210 and the light receiving sensor part 230 blocks a part of the light emitted from the light emitting sensor part 210, The amount of light received by the light receiving sensor unit 230 changes at a certain rate when the curled elastic member 110 moves in proportion to the thickness of the medium M to be sensed.

On the other hand, a portion indicated by a dotted line in FIG. 3 is an optical path of the above-mentioned light emitting light.

4 is a front view of only the slit member of the thickness detecting apparatus according to the embodiment of the present invention.

4, a plurality of slits 111 are formed in parallel on a wide surface of the slimming member 110 according to an embodiment of the present invention. The plurality of slits 111 are formed on the slimming member 110, May be formed so that the length gradually becomes shorter or shorter from one side to the other side. At this time, the width of the slit 111 may be constant.

The shape of the slit 111 is formed based on the movement amount of the curled elastic member 110 based on the thickness change of the detection subject medium and the performance of the light emission sensor part 210 and the light reception sensor part 230 good.

That is, when the size of the slit 111 is excessively large, there is no change in the amount of light received by the light receiving sensor 230 during the minute movement of the curtain wall member 110, The amount of light received by the light receiving sensor unit 230 may not change when the thin film member 110 is moved slightly.

Further, even when the number of the slits 111 passing the light emitted from the light emitting sensor unit 210 is small, there is no change in the amount of light received by the light receiving sensor unit 230.

Therefore, it is preferable to form the slit 111 based on at least one of the measurement resolution performance, the movement amount of the slit film member 110, and the initial position of the glass film member 110.

5 is an enlarged front view of a slit of a thickness detecting apparatus according to another embodiment of the present invention.

5, a plurality of slits 111 are formed in parallel on a wide surface of a slimming member 110 according to another embodiment of the present invention. The slits 111 are formed on the slimming member 110, The width may be gradually widened or narrowed from one side to the other side.

The slit 111 allows light emitted from the light emitting sensor unit 210 to pass therethrough and the light receiving sensor unit 230 located on the opposite side of the light emitting sensor unit 210 passes through the slit 111 The amount of light sensed by the light receiving sensor unit 230 can be changed at a predetermined ratio when the curtain wall member 110 moves.

For example, in the case of ordinary paper money, the thickness of one sheet is about 0.1 mm. If the resolution of the sensor is set to 0.01 mm in thickness and 0.5 mm in maximum thickness, it is sufficient to design the ratio of the amplifying lever so that the curled elastic member 110 has the maximum amount of movement for the medium M having a thickness of 0.5 mm. If the number of the slits 111 is about 100 in the step 50, there is a movement of two slits 111 in one step of 0.01 mm. At this time, about 20 slits (111) move relative to the initial position when one bill is inserted. Therefore, the sensor module including the light emitting sensor unit 210 and the light receiving sensor unit 230 increases the value at the time of entering the medium M from the initial value, regardless of the position, so that the initial position adjustment is unnecessary. Therefore, it is not necessary to adjust the position of the clearance A film member 110, which was a problem in the related art, to be located at the center between the light emitting sensor part 210 and the light receiving sensor part 230.

Accordingly, the lamp chamber member 110 is installed such that the light emitted from the light emitting sensor unit 210 covers at least a part of the amount of light received by the light receiving sensor unit 230 at the initial position and the maximum moving distance.

Meanwhile, the ratio of the amplifying lever can be adjusted by adjusting the length of the support member 103 corresponding to the amplifying lever to adjust the amount of movement of the elastic member 110 when the medium M is to be detected.

That is, when the change amount of the thickness of the detection target medium M is large, the movement amount of the curled elastic member 110 according to the thickness of the medium M can be reduced to increase the thickness detection range of the measurable medium M, It is possible to measure the thickness of the medium M more accurately by increasing the amount of movement of the glass film member 110 even when the thickness variation of the media M is small.

FIG. 6 is a plan view showing only a main portion of a thickness detecting apparatus according to another embodiment of the present invention. FIG.

6, the curtain wall member 110 may be made of transparent or semitransparent glass, plastic or the like that can transmit light, and may be thicker or thinner from one side to the other side .

According to another embodiment of the present invention, the light is transmitted through the skin member 110, and the thickness of the skin member varies from one side to the other side, thereby varying the amount of transmitted light.

Therefore, when the curtain wall member 110 moves, the light emitted from the light emitting sensor unit 210 is transmitted through the curtain wall member 110 or the difference in the amount of light transmitted through the curtain wall member 110 The amount of light sensed by the light receiving sensor unit 230 can be changed at a predetermined ratio.

At least one of the width and height of the slit 111 and the thickness of the slit member 110 may be changed at a certain ratio.

6, a portion indicated by a dotted line is a path of light transmitted from the light emitting sensor unit 210 to the light receiving sensor unit 230.

FIG. 7 is a use state view showing only the main portion in the order of (a), (b), and (c) in order to sequentially show the operation of the thickness detecting apparatus according to the embodiment of the present invention, (A), (b), and (c).

As shown in Fig. 7, the position of the curtain film member 110 before the medium M enters the thickness detecting device of the present invention is shown in Fig. 7 (a).

7 is a path of light transmitted from the light emitting sensor unit 210 to the light receiving sensor unit 230. As shown in FIG.

When one piece of medium enters the thickness detecting apparatus of the present invention, the curtain wall member 110 moves as shown in FIG. 7 (b).

In addition, when two media enter the thickness detecting device of the present invention, the curtain wall member 110 moves as shown in FIG. 7 (c).

The amount of light sensed by the light receiving sensor unit 230 when the curtain wall member 110 moves as shown in FIGS. 7A, 7B, and 7C changes at a constant rate with reference to FIG. 8 .

That is, the light receiving amount sensed by the light receiving sensor unit 230 increases proportionally with the thickness of the medium M, so that the thickness of the medium M can be calculated by measuring the amount of change in the light receiving amount of the light receiving sensor unit 230. On the other hand, the amount of received light of the light receiving sensor unit 230 may be reduced depending on the shape of the slit 111. [

The difference in the amount of light received by the light receiving sensor unit 230 when the medium is in the 1-day mode and the 2-day mode is k times as large as the size proportional constant of the slit 111, .

The initial light receiving amount of the light receiving sensor 230 may vary depending on the initial position of the curled elastic member 110, but the change ratio of the light receiving amount sensed by the light receiving sensor 230 is constant depending on the thickness of the medium , It is not necessary to manually adjust the position of the curled elastic member 110 to match the initial value. The change ratio of the amount of received light detected by the light receiving sensor unit 230 per one piece of media is the same regardless of the position of the curled elastic member 110 because the size of the slit 111 is constantly increased Because.

7 to 8, when the size proportional constant of the slit 111 is k, the amount of light received by the light receiving sensor unit 230 at the positions (b) and (c) is (b) = (a) - (a) = (k-1) (a) where k (a) and (b) - (b) = (k-1) (b) where the position of the curled elastic member 110 is located at any position The change ratio of the amount of received light of the light receiving sensor unit 230 per one medium is equal to (k-1).

Therefore, since the change in the amount of light received by the light-receiving sensor unit 230 per one medium is large and the change ratio is constant, the discriminating power of the medium thickness becomes large, and the false rate is reduced.

As described above, according to the thickness detecting apparatus of the present invention, since the shape of the glass film member 110 is changed from circular to slit type so that only one light receiving sensor can be used, the number of sensors can be minimized, This is advantageous.

In addition, there is an advantage in that it is not necessary to adjust the separate sensor board and bracket to align the curtain wall member 110 with the center.

Further, since the thickness of the medium M is detected by the ratio of the amount of change of the amount of light sensed by the light-receiving sensor unit 230, there is an advantage that the light-emitting sensor unit 210 is not sensitive to changes with time.

In addition, there is an advantage that it is not influenced by the vibration as compared with the conventional art.
