Description

An embodiment of the present invention relates to a coin roll opening device.

2. Description of the Related Art Conventionally, in retail stores, coin rolls in which a plurality of coins of the same denomination are packed in a bar shape (cylindrical shape) are used for replenishing change. Since the coin roll is wrapped in a resinous film, paper, or the like, it is necessary to tear open the wrapping before using the coins. For this reason, for example, there is known an example in which a coin roll is inserted into a hole provided with a cutter, and the cutter is used to tear a film, paper, or the like to open the coin roll (for example, Patent Literature 1).

However, in such a coin roll opening device, it is necessary to periodically replace the blade in order to maintain the sharpness of the cutter. In addition, since a cutter is used, there is a possibility that the body may come into contact with it by mistake.

SUMMARY OF THE INVENTION An object of the present invention is to provide a coin-roll opening device that does not require replacement of parts and can easily open a coin-roll.

A coin roll opening device of an embodiment includes an opening, a hole, a contact portion, and a pressure receiving portion. A coin roll in which a plurality of coins are wrapped in a bar shape is inserted into the opening. The hole can insert a coin roll to a depth corresponding to the coin roll, and when the coin roll is inserted, the movable hole moves to a position corresponding to the thickness of the coin roll while contacting the coin roll. Equipped with walls . The contact portion is formed in the hole and restricts movement of the coin roll in a direction other than the insertion direction. The pressure receiving portion is formed in the vicinity of the opening, and receives a pressing force in a direction substantially orthogonal to the direction of the coin roll against one end side of the coin roll that is not inserted into the hole.

(Description of the function of the coin roll opening device)
As shown in FIG. 1( a ), the coin-roll opening device 10 has a hole 24 having an opening 22 in a substantially rectangular parallelepiped casing 20 . The housing 20 is formed by joining a housing 20a and a housing 20b by adhesion, screwing, or the like. The opening 22 is formed at the joint between the housing 20a and the housing 20b and has a shape (for example, a substantially circular shape) into which the metal roll 90 can be inserted. The hole portion 24 is formed from the opening portion 22 toward the inside of the housing 20 so that the metal roll 90 can be inserted up to a position corresponding to approximately half the length of the metal roll 90 . A specific internal structure of the hole portion 24 will be described later. For the sake of the following description, the direction in which the hole 24 of the coin-roll opening device 10 extends is defined as the X-axis, the width direction of the coin-roll opening device 10 is defined as the Y-axis, and the height direction of the coin-roll opening device 10 is defined as the Z-axis. Set the XYZ coordinate system to be

As shown in FIG. 1B, a metal roll 90 can be inserted into the hole 24 that continues to the opening 22 of the housing 20 . The coin roll 90 is formed by stacking a plurality of coins 93 of the same denomination in a cylindrical shape and wrapping them with a film 92 . Here, the coin 93 is an example of a coin. The coin roll 90 is generally a bar-shaped package of coins used as currency or medals used in game machines or the like. In this embodiment, for example, a coin roll 90 in which fifty coins 93 are stacked will be described as an example.

With the metal roll 90 inserted into the hole 24 , the direction of the arrow F shown in FIG. A pressing force is applied in an orthogonal direction (Z-axis negative direction). Then, as shown in FIG. 1C, the film 92 wrapping the metal roll 90 is opened at the position of the opening 22 of the hole 24 . The detailed opening mechanism will be described later.

When the metal roll 90 is unsealed, of the film 92 wrapping the metal roll 90, the film 92 on the Z-axis negative side remains partially uncut (residual film portion 94). In this way, the coin roll 90 is separated into a coin-roll piece 90x that hangs outside the housing 20 and a coin-roll piece 90y that remains inside the hole 24 . The housing 20 has an abutting portion 26 against which the metal bar piece 90x abuts. The abutting portion 26 is formed so as to be substantially flush with the surface formed by the peripheral edge of the opening 22, and is abutted against the side surface of the metal bar piece 90x. In the example of FIG. 1C , the abutting portion 26 is the outer peripheral surface of the housing 20 that continues from the periphery of the opening 22 . In order to unseal the film 92 with certainty, it is desirable that the metal bar piece 90x and the metal bar piece 90y after being opened form an angle of approximately 90 degrees. That is, it is desirable that the insertion direction of the metal roll 90 and the surface formed by the abutting portion 26 form an angle of approximately 90 degrees.

The operator who has opened the coin roll 90 takes out the coin roll piece 90x and the coin roll piece 90y from the housing 20 by grasping the coin roll piece 90x and pulling it out from the hole 24 . Subsequently, the operator pulls the coin-roll piece 90x and the coin-roll piece 90y to open the coin-roll piece 90x and the coin-roll piece 90y from the position of the remaining film portion 94, respectively, and takes out the coin.

(Description of the internal structure of the coin roll opening device)
Next, the internal structure of the coin-roll opening device 10 will be described with reference to FIGS. 2 and 3. FIG. FIG. 2 is an XZ cross-sectional view of a part of the coin-roll opening device 10 taken substantially at the center of the hole 24. As shown in FIG.

The hole 24 is formed following the opening 22, allows the metal roll 90a to be inserted to a depth corresponding to the metal roll 90a, and has a diameter corresponding to the thickness of the metal roll 90a. In the coin-roll opening device 10 shown in FIG. 4, the hole 24 is formed in a substantially circular shape. Inside the hole 24, a first bottom 28a, a second bottom 28b, and a third bottom 28c are formed stepwise. The first bottom portion 28 a is formed at a depth D<b>1 from the opening 22 . The second bottom portion 28b is formed at a depth D2 from the opening 22. As shown in FIG. The third bottom portion 28c is formed at a depth D3 from the opening 22. As shown in FIG.

The diameter d1 of the first bottom portion 28a is set to d1=27 mm, for example. A diameter d2 of the second bottom portion 28b is set to d2=24 mm, for example. A diameter d3 of the third bottom portion 28c is set to d3=21.5 mm, for example. That is, the metal roll 90 having a diameter of d3 or less can be inserted up to the position of the third bottom portion 28c. Also, the metal roll 90 having a diameter of d3 to d2 (d3<d2) can be inserted up to the position of the second bottom portion 28b. A metal roll 90 having a diameter of d2 to d1 (d2<d1) can be inserted up to the position of the first bottom portion 28a.

Coins used in Japan include 1-yen coins (20.0 mm in diameter), 5-yen coins (22.0 mm in diameter), 10-yen coins (23.5 mm in diameter), and 50-yen coins (21.0 mm in diameter). , 100 yen coin (22.6 mm in diameter), and 500 yen coin (26.5 mm in diameter). Small (thin) 1-yen coins and 50-yen coins can be inserted up to the position of the third bottom portion 28c. A 5-yen coin, a 10-yen coin, and a 100-yen coin having an intermediate diameter can be inserted up to the position of the second bottom portion 28b. A 500-yen coin with a large diameter (thick) can be inserted up to the position of the first bottom portion 28a. Hereinafter, for convenience of explanation, the coin roll 90 of 1 yen coins and the coin roll 90 of 50 yen coins will be referred to as a coin roll 90a. The coin roll 90 of 5 yen coins, the coin roll 90 of 10 yen coins, and the coin roll 90 of 100 yen coins are referred to as a coin roll 90b (not shown). The coin roll 90 of 500-yen coins is called a coin roll 90c (not shown). Note that FIG. 2 shows an example in which the metal roll 90a is inserted to the position of the third bottom portion 28c.

The depth D1 of the first bottom portion 28a, the depth D2 of the second bottom portion 28b, and the depth D3 of the third bottom portion 28c are respectively determined by the depth of the hole portion 24 when the metal roll 90 is inserted deep into the hole portion 24. It is desirable to set the length of the side inserted into 24 and the length of the portion not inserted into hole 24 to be substantially equal. For example, D1=30 mm, D2=40 mm, and D3=50 mm. By setting the depths D1, D2, and D3 of the hole 24 in this manner, the length of the portion of the coin roll 90 that is not inserted into the hole 24 is approximately half the length of the coin roll 90. Therefore, when the coin roll 90 is unsealed, it is easy to apply a pressing force to the portion protruding from the housing 20 , that is, the side of the coin roll 90 that is not inserted into the hole 24 .

A bending member 30 having an opening area slightly smaller than the area of the opening 22 is installed near the opening 22 . The bending member 30 is a plate-like member made of metal such as iron.

In the state shown in FIG. 2, of the metal rolls 90a inserted into the holes 24, a pressing force is applied in the direction of arrow F, which is substantially perpendicular to the direction of the metal rolls 90a, to the end of the metal roll 90a that is not inserted into the hole 24. Then, the metal bar 90a contacts the wall surface of the hole 24 at the contact portion 27 in the vicinity of the third bottom portion 28c. That is, the contact portion 27 is formed in the hole portion 24 and restricts movement of the metal bar 90a in directions other than the insertion direction. Further, the metal bar 90a comes into contact with the bending member 30 at the pressure receiving portion 32, as shown in FIG. That is, the pressure receiving portion 32 is formed in the vicinity of the opening 22 and receives a pressing force in a direction substantially perpendicular to the direction of the metal roll 90a against one end side of the metal roll 90a that is not inserted into the hole 24 . Note that the shape of the pressure receiving portion 32 is determined by the shape of the bending member 30 . That is, the pressure receiving portion 32 may be brought into contact with the outer surface of the metal roll 90a at one point, or may be brought into contact with a portion of an arc formed by the outer surface of the metal roll 90a in a curved shape.

Next, the cross-sectional shape of the hole portion 24 will be described with reference to FIG. 3 is a YZ sectional view showing the internal structure of the hole portion 24 of the coin-roll opening device 10 shown in FIG. 2, and FIG. 3(a) is an AA sectional view. FIG. 3(b) is a cross-sectional view taken along line BB. FIG. 3(c) is a sectional view taken along the line CC.

As shown in FIG. 3A, the hole 24 has a first bottom 28a, a second bottom 28b, and a third bottom 28c formed stepwise. The first bottom portion 28a is a region of the width (d1-d2)/2 of the peripheral portion of the hole portion 24 having the diameter d1. Then, the metal roll 90c (not shown) can be inserted up to the position of the first bottom portion 28a. The area inside the first bottom portion 28a has a substantially circular shape, and this area has an area through which the coin roll 90a (see FIG. 2) and the coin roll 90b (not shown) can pass.

Further, as shown in FIG. 3B, the second bottom portion 28b is a region of the peripheral width (d2-d3)/2 of the hole portion 24 having the diameter d2. Then, the metal roll 90b (not shown) can be inserted up to the position of the second bottom portion 28b. The area inside the second bottom portion 28b has a substantially circular shape, and this area has an area through which the metal roll 90a (see FIG. 2) can pass.

As shown in FIG. 3(c), the third bottom portion 28c is the area of the hole portion 24 with a diameter d3 and has a substantially circular shape. Then, the metal roll 90a (see FIG. 2) can be inserted up to the position of the third bottom portion 28c.

(Description of the action of the coin roll opening device)
Next, the operation of the coin-roll opening device 10 will be described with reference to FIG. FIG. 4 is an XZ sectional view of the coin-roll opening device 10 showing a state in which the coin-roll 90a is opened.

When a further pressing force is applied to the metal roll 90a in the direction of arrow F shown in FIG. The pressing force applied in the direction of arrow F (see FIG. 2) is concentrated at a point 32a (see FIG. 2) opposite to the point where the metal roll 90a contacts the pressure receiving portion 32. As shown in FIG. When a further pressing force is applied, the tensile force of the film 92 wrapping the metal bar 90a cannot withstand the force that moves the metal bar 90a to the negative side of the Z axis, and the film 92 breaks at the point 32a.

That is, when a pressing force is applied in a direction substantially perpendicular to the direction of the metal roll 90a to the one end side of the metal roll 90a that is not inserted into the hole 24, the point where the pressing force is applied acts as a force point. The point of the metal bar 90a that contacts the hole 24 at the contact portion 27 acts as a fulcrum. Further, the point of contact with the bending member 30 in the pressure receiving portion 32 acts as a point of action. As a result, a force in the direction of bending the metal roll 90a can be applied to the metal roll 90a. The breakage of the film 92 at the point 32a is propagated in the direction perpendicular to the direction of the metal bar 90a (approximately the negative direction of the Z-axis), so the film 92 is broken along the Z-axis. Then, the side surface of the metal roll 90a bends and moves to a position where it abuts against the outer surface of the housing 20, that is, the abutting portion 26. As shown in FIG.

In this manner, the metal roll 90a can be unsealed at the position of the bending member 30. FIG. Since the breakage of the film 92 stops when the metal-roll piece 90x hits the abutting portion 26, the metal-roll piece 90x and the metal-roll piece 90y are connected by the residual film portion 94 that remains unbroken. state. Incidentally, if the housing 20 has sufficient strength to withstand the bending of the metal roll 90a, the bending member 30 may not be installed.

Note that the direction of the pressing force applied to the metal roll 90a is not always constant. When the direction of the pressing force changes, the position of the contact portion 27 changes within the inner wall of the hole portion 24 according to the direction of the pressing force. As the position of the contact portion 27 changes, the position of the pressure receiving portion 32 also changes.

Also, the depth to which the metal roll 90a is inserted is not always constant. When the depth into which the metal bar 90a is inserted changes, the position of the contact portion 27 changes within the inner wall of the hole portion 24 accordingly. As the position of the contact portion 27 changes, the position of the pressure receiving portion 32 also changes.

In order to effectively transmit the pressing force to the metal bar 90a and easily open the metal bar 90a, the position of the contact portion 27 formed by contacting the tip of the metal bar 90a is It is desirable that the coin roll 90a does not move due to slippage or the like until the coin roll 90a is unsealed. Therefore, it is desirable that the inner wall of the hole 24, particularly the region where the contact portion 27 may be formed, is given a satin finish, for example, so as to have an anti-slip effect.

The case where the coin roll 90a is unsealed has been described above, but the unsealing mechanism is the same for the coin rolls 90b and 90c (not shown).

(Explanation of modification of embodiment)
In the embodiment described above, the hole 24 has a cross-sectional area that decreases in a stepped manner toward the back (X-axis negative direction), but the shape of the hole 24 is not limited to this. do not have.

FIG. 5 is an XZ cross-sectional view and a YZ cross-sectional view showing a modification of the hole portion 24 of the coin-roll opening device 10. As shown in FIG. In particular, FIG. 5(a) shows an example in which a hole portion 24a is formed by eliminating the step of the inner wall lower portion 34, which is the inner wall on the Z-axis negative direction side, of the hole portion 24 described in the embodiment. FIG. 5(b) shows an example in which rib-like bottom portions 38a and 38b are formed on the inner wall upper portion 36a of the hole portion 24a to form the hole portion 24b. FIG. 5C shows an example in which the inner wall upper portion 36b, which is the inner wall on the positive side of the Z-axis with respect to the hole portion 24a, is formed as a hole portion 24c whose cross-sectional area decreases in a conical shape toward the inner side. be.

According to the hole portion 24a of FIG. 5(a), as shown in the DD cross-sectional view (YZ cross-sectional view) taken along the cutting line DD of the XZ cross-sectional view of FIG. There are no steps. Therefore, when the metal roll 90 is inserted through the opening 22, the metal roll 90 can be inserted deep into the hole 24a while being brought into contact with the inner wall lower portion 34. As shown in FIG. Therefore, it becomes easier to insert the metal roll 90 .

According to the hole portion 24b of FIG. 5B, since there is no step in the inner wall lower portion 34, when inserting the coin roll 90 from the opening 22, the coin roll 90 can be easily inserted. Furthermore, according to the hole portion 24b, since the rib-shaped bottom portions 38a and 38b are formed on the inner wall upper portion 36a, the weight of the housing 20 can be reduced compared to the hole portion 24 described above.

According to the hole portion 24c of FIG. 5C, the cross-sectional area of the hole portion 24c becomes smaller in the shape of a cone toward the inner side. It can be inserted all the way into the hole 24c while making contact with 36b or the inner wall lower portion 34. As shown in FIG. Therefore, it becomes easier to insert the metal roll 90 .

The coin-roll opening device 10 may be manufactured in the form shown in FIG. , a drawer device, a register stand, or the like.

As described above, according to the coin-roll opening device 10 , the direction of the coin-roll 90 inserted from the opening 22 into the hole 24 is substantially perpendicular to the direction of the coin-roll 90 . By applying a pressing force in the direction of the pressing force, the tip of the metal roll 90 comes into contact with the position of the hole portion 24 according to the direction of the pressing force, thereby restricting the movement of the metal roll 90 in a direction other than the insertion direction. A contact portion 27 is formed. A pressure receiving portion 32 that receives the pressing force is formed near the opening 22 at a position corresponding to the direction of the pressing force against one end of the metal roll 90 and the position of the contact portion 27 . The formed abutting portion 27 acts as a fulcrum and causes a force corresponding to the applied pressing force to act on the pressure receiving portion 32 which is the point of action, thereby tearing the film 92 wrapping the metal bar 90 . Therefore, the coin roll 90 can be easily opened. In addition, since the coin-roll opening device 10 does not use a part such as a cutter that requires replacement, there is no need to replace the part.

Further, according to the coin-roll opening device 10, the hole portion 24 has a shape in which the cross-sectional area decreases in a stepwise manner toward the inner side. Therefore, when the metal rolls 90 (90a, 90b, 90c) having different thicknesses are inserted into the hole portion 24, the metal rolls 90 are reliably inserted to positions corresponding to the thicknesses, and the contact portion 27 is moved. can be formed.

Then, according to the coin-roll opening device 10, the hole portion 24c has a shape in which the cross-sectional area decreases in the shape of a cone toward the inner side. Therefore, when the metal bars 90 (90a, 90b, 90c) having different thicknesses are inserted into the hole 24c, the metal bars 90 can be easily inserted while being in contact with the wall surface of the hole 24c. In FIG. 5(c), the inner wall upper portion 36b and the inner wall lower portion 34 may be exchanged so that the inner wall upper portion is parallel to the X-axis and the inner wall lower portion is an inclined surface that is lower in the positive direction of the X-axis. When the hole portion 24c having such a shape is formed, the metal bar piece 90y (see FIG. 4) remaining in the hole portion 24c slides down toward the positive direction of the X-axis, that is, toward the opening portion 22. can be made easy to take out the metal bar piece 90y.

(Second embodiment)
Next, a second embodiment will be described. FIG. 6(a) is an external perspective view of a coin roll opening device 10a of the second embodiment. FIG. 6(b) is an external perspective view showing a state in which the coin roll 90 is inserted into the coin roll opening device 10a. FIG. 6(c) is an external perspective view showing a state in which the coin roll 90 is opened by the coin-roll opening device 10a.

As shown in FIG. 6(a), the coin-roll opening device 10a has an opening 22a and a hole 25 continuing to the opening 22a. The opening 22 a is formed so as to have an opening on the positive Y-axis side of the housing 21 in addition to the positive X-axis side of the housing 21 . The opening 22a allows the metal roll 90 to be inserted into the hole 25 not only from the positive direction of the X-axis, but also from the side of the metal-roll 90, that is, from the positive direction of the Y-axis.

The internal shape of the hole portion 25 is the same as that of the hole portion 24 described in the first embodiment. That is, the metal rolls 90 having different thicknesses can be inserted to a depth corresponding to each metal roll 90 . A bending member 30a is installed at the end of the opening 22a on the positive side of the X axis. The bending member 30a is U-shaped to match the shape of the opening 22a. The internal shape of the hole portion 25 may be the shape shown in FIG.

A metal roll 90 is inserted into the hole 25, as shown in FIG. 6B, for example. By applying a pressing force from the direction of the arrow F to the inserted coin roll 90 in the same manner as in the first embodiment, the coin roll opening device 10a has a contact portion 27 and a pressure receiving portion (not shown in FIG. 6). 32 are formed. Then, the coin roll 90 is unsealed as shown in FIG. 6(c). The unsealed coin roll 90 is divided into a coin roll piece 90x and a coin roll piece 90y, as in the first embodiment. Then, the metal bar piece 90x and the metal bar piece 90y are connected by the remaining film portion 94. As shown in FIG.

The unsealed coin roll 90 is taken out through the opening 22a. At that time, the coin roll 90 may be taken out from the positive direction of the X-axis or from the positive direction of the Y-axis. In FIG. 6A, the hole 25 is formed in the direction (horizontal direction) extending along the Y-axis from the opening formed in the positive direction of the Y-axis. It may be formed with an inclination so as to As a result, the coin roll 90 inserted into the hole 25 slides down along the slope in the negative Y-axis direction, so that the inserted coin-roll 90 is less likely to fall out of the opening in the positive Y-axis direction. Further, the surface of the hole portion 25 that continues to the opening of the housing 21 on the positive side of the X axis may be an inclined surface that becomes lower toward the positive side of the X axis. In this case, as described above, the coin-roll piece 90y remaining in the hole 25 slides down in the positive direction of the X-axis, making it easier to take out the coin-roll piece 90y after opening.

As described above, according to the coin-roll opening device 10a, the opening 22a is formed so that the coin-roll 90 can be inserted into the hole 25 even from the side. Therefore, insertion of the metal roll 90 becomes much easier. Furthermore, according to the coin-roll opening device 10a, scraps of the film 92 accumulated inside the hole portion 25 and dust accumulated inside the hole portion 25 can be easily cleaned.

(Third embodiment)
Next, a third embodiment will be described. FIG. 7(a) is an external perspective view of a coin roll opening device 10b of the third embodiment. FIG. 7(b) is an XZ sectional view of the coin-roll opening device 10b. FIG. 7(c) is an external perspective view of the metal-roll pressing piece 40a.

As shown in FIG. 7( a ), the coin-roll opening device 10 b has a substantially rectangular housing 23 with a hole 44 having an opening 22 . The housing 23 is formed by joining a housing 23a and a housing 23b by bonding, screwing, or the like. The opening 22 is formed at the joint between the housing 23a and the housing 23b, and has a shape (for example, a substantially circular shape) into which the metal roll 90 can be inserted. The hole portion 44 is formed from the opening 22 toward the inside of the housing 23 , and inserts the coin roll 90 (not shown) to a depth corresponding to the coin roll 90 , for example, approximately half of the coin roll 90 . It is possible to insert up to a position corresponding to the length. A specific internal structure of the hole portion 44 will be described later. For the following explanation, the direction in which the hole 44 of the coin-roll opening device 10b extends is defined as the X-axis, the width direction of the coin-roll opening device 10b is defined as the Y-axis, and the height direction of the coin-roll opening device 10b is defined as the Z-axis. Set the XYZ coordinate system to be

As shown in FIG. 7(b), inside the hole portion 44, a metal-roll pressing piece 40a is provided on the housing 23a side. Further, a metal-roll pressing piece 40b (see FIG. 8) is provided on the housing 23b side. The coin-roll holding piece 40a and the coin-roll holding piece 40b have the same shape and are installed facing each other.

The coin-roll holding piece 40a has an inner wall 43a as shown in FIG. 7(c). The inner wall 43a has a concave shape whose diameter gradually decreases from the X-axis positive side toward the X-axis negative side. The shape of the inner wall 43a is the same as the shape of the hole portion 24c (see FIG. 5C), and guides the inserted metal roll 90 to a position corresponding to the thickness of the metal roll 90. As shown in FIG. Note that a metal bar holding piece 40b (see FIG. 8A) provided inside the housing 23b also has an inner wall 43b (see FIG. 8A) having the same shape.

A sliding portion 41a and a sliding portion 42a are formed at upper and lower positions in the Z-axis direction of the metal bar pressing piece 40a. The sliding portion 41a and the sliding portion 42a are respectively fitted into groove portions 29a and 31a formed inside the housing 23a. The sliding portions 41a and 42a function as guide members when the metal bar holding piece 40a is slid in the Y-axis direction inside the housing 23a.

A bottom surface 48 a is formed at the deepest position of the hole portion 44 . A bending member 30 is provided in the vicinity of the opening 22 in the same manner as the coin-roll opening device 10 of the first embodiment.

A metal roll 90 is inserted into the hole 44 from the opening 22 . Then, the tip side of the inserted metal roll 90 is inserted up to the position of the bottom surface 48a. At this time, if a pressing force is applied to one end of the metal roll 90 that has not been inserted into the hole 44 , the leading end of the metal roll 90 that has been inserted into the hole 44 abuts against the inner wall of the hole 44 . A contact portion 27 (see FIG. 4) is formed. At this time, a pressure receiving portion 32 (see FIG. 4) for unsealing the metal roll 90 is formed at the end portion of the bending member 30 .

Next, the internal structure of the hole portion 44 will be described with reference to FIG. FIG. 8(a) is a YZ sectional view (EE sectional view of FIG. 7(b)) of the coin-roll opening device 10b. FIG. 8(b) is an XY cross-sectional view (FF cross-sectional view of FIG. 7(b)) of the coin-roll opening device 10b.

As shown in FIGS. 8(a) and 8(b), the coin-roll holding piece 40a and the coin-roll holding piece 40b are installed with the inner walls 43a and 43b facing each other. Note that the coin bar pressing pieces 40a and 40b are examples of movable wall portions.

As shown in FIG. 8(a), a spring 50a, which is an elastic body, is connected between the surface of the metal bar holding piece 40a on the Y-axis negative side and the housing 23a. A spring 50b, which is an elastic body, is connected between the surface of the metal bar holding piece 40b on the positive side of the Y axis and the housing 23b. Springs 50a and 50b are, for example, metal springs. The coin-roll holding piece 40a and the coin-roll holding piece 40b are pressurized by the springs 50a and 50b, respectively, and are held in contact with each other.

The sliding portion 41a and the sliding portion 42a provided on the metal bar holding piece 40a are fitted into the groove portions 29a and 31a as described above. The sliding portions 41a and 42a are guided by the groove portions 29a and 31a to allow the metal bar pressing piece 40a to slide in the Y-axis direction. A sliding portion 41b and a sliding portion 42b provided on the metal bar pressing piece 40b are fitted into the grooves 29b and 31b, respectively. The sliding portions 41b and 42b are guided by the groove portions 29b and 31b to allow the metal bar pressing piece 40b to slide in the Y-axis direction.

As shown in FIG. 8B, the inner wall 43a of the coin-roll pressing piece 40a and the inner wall 43b of the coin-roll pressing piece 40b gradually decrease in diameter in the negative direction of the X-axis. When a metal bar 90 (not shown) is inserted through the opening 22, the metal bar 90 abuts against the inner wall 43a and the inner wall 43b. Move toward the negative side of the axis. At this time, the coin-roll holding pieces 40a and 40b receive the elastic force of the springs 50a and 50b, respectively, so as to guide the insertion of the coin-roll 90. As shown in FIG.

Next, the operation when coin rolls 90a and 90c having different thicknesses are inserted into the coin-roll opening device 10b will be described with reference to FIG. FIG. 9(a) is an XY cross-sectional view (FF cross-sectional view of FIG. 7(b)) showing a state in which a thin metal roll 90a is inserted into the coin-roll opening device 10b. FIG. 9(b) is an XY cross-sectional view (FF cross-sectional view of FIG. 7(b)) showing a state in which a thick coin roll 90c is inserted into the coin-roll opening device 10b.

As shown in FIG. 9A, when a thin coin roll 90a is inserted into the coin-roll opening device 10b, the tip of the coin-roll 90a enters the housings 23a and 23b while abutting against the inner walls 43a and 43b. do. At this time, the metal roll 90a applies a force to open the inner walls 43a and 43b in the Y-axis direction. The coin-roll pressing piece 40a moves in the Y-axis negative direction due to this pushing-open force. At this time, the sliding portions 41a and 42a (see FIG. 7B) provided at the upper and lower positions in the Z-axis direction of the metal bar pressing piece 40a move the groove portions 29a and 31a of the housing 23a (see FIG. 8A). slide along. Therefore, the coin-roll holding piece 40a moves in the Y-axis negative direction according to the insertion position of the coin-roll 90a while maintaining its posture. Then, the metal bar holding piece 40a is pressed in the positive direction of the Y-axis by the elastic force of the spring 50a. Therefore, the coin-roll holding piece 40a moves to a position where the force pushed in the Y-axis negative direction by the coin-roll 90a and the force pushed in the Y-axis positive direction by the spring 50a are balanced.

The coin-roll pressing piece 40b having the inner wall 43b also moves inside the housing 23b in the same manner as the coin-roll pressing piece 40a. That is, the coin-roll holding piece 40b receives a force that pushes it open in the positive direction of the Y-axis as the coin-roll 90a is inserted. At this time, the sliding portions 41b and 42b (see FIG. 8A) provided at the upper and lower positions in the Z-axis direction of the metal bar pressing piece 40b move the grooves 29b and 31b (see FIG. 8A) of the housing 23b. slide along. Therefore, the coin-roll holding piece 40b moves in the positive direction of the Y-axis according to the insertion position of the coin-roll 90a while maintaining its posture. Then, the metal bar holding piece 40b is pressed in the Y-axis negative direction by the elastic force of the spring 50b. Therefore, the coin-roll holding piece 40b moves to a position where the force pushed in the positive direction of the Y-axis by the coin-roll 90a and the force pushed in the negative direction of the Y-axis by the spring 50b are balanced.

The tip of the inserted metal bar 90 a reaches the bottom surfaces 48 a and 48 b of the hole 44 . The bottom surface 48b is the bottom surface of the hole 44 formed on the housing 23b side. At this time, the inner wall 43a and the inner wall 43b are in a state of being pushed apart, but since the springs 50a and 50b act on the inner walls 43a and 43b in the direction of pinching the metal roll 90a, the metal roll 90a rattles. It is gripped by the coin-roll pressing pieces 40a and 40b.

When the metal roll 90a is inserted up to the bottom surfaces 48a and 48b, as described in the first embodiment, the metal roll 90a is positioned at one end of the metal roll 90a that is not inserted into the hole 44. A pressing force is applied in a direction substantially orthogonal to the direction of , that is, substantially in the negative direction of the Z-axis. Then, the tip of the metal bar 90a contacts the inner wall of the hole 44 to form the contact portion 27 (not shown in FIG. 9A). The opening 22 side of the metal bar 90 a abuts on the bending member 30 to form a pressure receiving portion 32 . With the abutting portion 27 and the pressure receiving portion 32 formed in this manner, if a further pressing force is applied, the metal roll 90 a is unsealed at a position corresponding to the abutting portion 27 and the pressure receiving portion 32 .

On the other hand, as shown in FIG. 9(b), when a thick coin roll 90c is inserted, the coin-roll pressing pieces 40a and 40b operate similarly. In this case, since the metal roll 90c is thicker than the metal roll 90a, the amount of movement of the metal roll pressing pieces 40a and 40b is greater than in the case of FIG. 9(a). However, even in this case, the tip of the metal roll 90c is inserted up to the positions of the bottom surfaces 48a and 48b. Then, in the same manner as described above, when a pressing force directed in a direction substantially perpendicular to the direction of the metal roll 90c is applied to the one end of the metal roll 90c that is not inserted into the hole 44, the contact portion 27 ( ) and the pressure receiving portion 32 are formed, and the metal roll 90 c is unsealed at a position corresponding to the contact portion 27 and the pressure receiving portion 32 .

As described above, according to the coin-roll opening device 10b, when the coin-roll 90 is inserted, the hole portion 44 moves to a position corresponding to the thickness of the coin-roll 90 while contacting the coin-roll 90. The metal bar pressing pieces 40a and 40b (movable walls) are provided. Therefore, the tip of the metal roll 90 (90a, 90b, 90c) can be inserted to the position of the bottom surfaces 48a, 48b of the hole 44 regardless of the thickness of the metal roll 90 (90a, 90b, 90c). Therefore, the length of the portion of the metal roll 90 inserted into the hole 44 protruding from the opening 22 is approximately equal regardless of the thickness of the metal roll 90. The metal roll 90 can be unsealed with approximately the same pressing force.
