An arrival detection sensor 26 detects the front end of the bill P conveyed while being guided by the first and second conveyance guides 18a and 18b, and corresponds to the protruding portions 23 on both sides, and its feeding direction. Downstream of the banknotes P provided on the transport line of the protrusion 23 (referred to as virtual lines set parallel to each other along the feed direction on the transport surfaces 19a and 19b) and fed by the feed roller 15. The distance until the rear end is at the deposit / withdrawal port 2, that is, the distance along the conveyance line from the bottom surface of the deposit / withdrawal port 2, is set at a position where the length of the banknote P in the feeding direction is shorter than one.

  As shown in FIG. 2, the arrival detection sensor 26 of the present embodiment is disposed opposite to each other across a transmission hole 27 that transmits light from the light emitting portion 26a provided in each of the first and second transport guides 18a and 18b. It is an optical sensor formed by the light emitting part 26a and the light receiving part 26b, and the position where the light transmitted through the transmission hole 27 is blocked by the front end of the bill P is arranged to be the above position. Yes.

In addition, a pair of conveyance roller 20 is provided in the downstream of the arrival detection sensor 26, and becomes a structure which conveys the banknote P which passed the arrival detection sensor 26 further downstream.
Deposit / withdrawal processing of banknotes P with no folds by the banknote deposit / withdrawal apparatus 1 is performed as follows.
In the case of deposit processing, when a transaction with a customer is started and banknotes P are loaded all at once with the shutter 1a of the deposit / withdrawal port 2 opened, the shutter 1a is closed and the deposit / withdrawal port 2 is opened. The bills P are separated and fed one by one by the feeding unit 12, and are conveyed while being guided by the pair of conveyance guides 18 and delivered to the first conveyance path 8a.

At the time of the feeding operation of the deposit bill, the folded bill is detected in this embodiment, and the folded bill is returned to the deposit / withdrawal port 2 to prompt the customer to correct the fold and re-insert it. However, as will be described in detail later, the entire operation of the banknote depositing / dispensing apparatus 1 in the case of the banknote P without a fold will be described first.
The banknote P delivered to the first transport path 8a is transported in the feeding direction by the first transport path 8a and sent to the discrimination unit 3, and the discrimination unit 3 discriminates the correctness of the banknote P, the denomination, and the like. , And conveyance anomalies such as chain and skew are detected.

As a result, the banknote P with an unknown denomination or the banknote P in which the conveyance abnormality is detected is sent back to the deposit / withdrawal port 2 as a deposit reject banknote through the second transport path 8b, and is distinguished from the inserted banknote P and accumulated. Is done.
Moreover, the banknote P discriminated from the non-withdrawal denomination, and the banknote P discriminated from the non-withdrawal denomination denominated by the shape recognition of the outer shape of the banknote P although the denomination is discriminated, 1 is sent to the temporary holding unit 4a by the one conveyance path 8a and temporarily held.

On the other hand, the banknotes P, which are suitable for withdrawal with a denomination target and are distinguished from a genuine note suitable for taking-in processing into the apparatus, are temporarily held by the first transport path 8a. To be temporarily held in denomination.
When all the banknotes P inserted into the deposit / withdrawal port 2 are paid out and the discrimination is completed, the shutter 1a is opened and the deposit reject banknote is returned to the customer.

When the transaction is confirmed, the banknotes P accumulated in the temporary holding sections 4a to 4d are taken into the corresponding banknote storage sections 5a to 5d and stored in denominations.
In the case of a withdrawal process, when a transaction with a customer is started, a bill P is fed out from the bill storage units 5b to 5d, and the bill P is transported through the first transport path 8a in the direction opposite to the feeding direction. It is sent to the discriminating unit 3 and the conveyance abnormality such as discrimination, denomination, chaining, skewing, etc. is detected.

As a result, a partially broken or missing banknote (a banknote stored in the banknote storage units 5b to 5d by replenishment or the like) or a banknote P in which a transport abnormality is detected is a third transport path as a withdrawal reject banknote. 8c and is stored in the reject banknote storage 6 by the third transport path 8c.
The banknote P, which has been identified as a genuine note by the discrimination unit 3 and whose denomination has been determined, is conveyed by the first conveyance path 8a and accumulated in the deposit / withdrawal port 2.

When banknotes P corresponding to the denomination and amount specified in advance by the customer are accumulated at the deposit / withdrawal port 2, the shutter 1a is opened and paid out to the customer.
When the customer forgets to remove the banknote P, the banknote P is sent to the second transport path 8b side in the deposit / withdrawal port 2 and fed out to the second transport path 8b, and the discrimination section from the first transport path 8a. 3 is sent to and stored in the banknote storage unit 7 forgotten by the fourth transport path 8d.

In the above deposit processing, an operation when a folded bill is inserted will be described.
In FIG. 2, the bills P inserted into the deposit / withdrawal port 2 by the customer are accumulated in a standing position in the deposit / withdrawal port 2, and the uppermost bill P is pressed against the pickup roller 13 by the bill holder 14, and the pickup roller 13 and the feeding roller 15 and the gate roller 16 are separated one by one and fed downstream.

At this time, the time (arrival time) from when a monitoring sensor (not shown) detects the front end of the bill P fed by the feeding roller 15 and the gate roller 16 until the arrival detection sensors 26 on both sides detect the front end of the bill P. ) Is counted, and the posture and conveyance state of the banknote P can be detected from the arrival time.
That is, when the bill P is skewed, a time difference occurs in the arrival times detected by the left and right arrival detection sensors 26, and the skew of the bill P is detected when the time difference is equal to or greater than a predetermined time difference. The

By the way, the banknote P which a customer throws in is the banknote P with the folding fold as shown in FIG. 7, ie, the longitudinal direction of the banknote P is halved, and the fold mountain 30 and the fold valley 31 which were further halved are asymmetrical. There are many four-fold folded bills, and when such folded bills are transported downstream, there is a risk that many bill jams will occur, particularly in the transport path 8 that curves the bills P outward.
For example, in the branch part 10b which branches the banknote P conveyed by the 1st conveyance path 8a to the temporary storage part 4a etc., as shown in FIG. 6, the banknote P conveyed in the arrow D direction protrudes outside. In the case where the switching blade 11 guides downward in FIG. 5 as described above, the front end of the folded pile 30 of the folded paper money conveyed in the D direction is being guided downward along the curved guide surface 11a. When the paper is conveyed corresponding to the boss portion 11c, the folded mountain 30 is conveyed so as to rise to the upper side of the conveying path 8 as shown in FIG. 6, and collides with the boss portion 11c to generate a bill jam. To do.

The operation in the present embodiment when such a broken paper banknote with the possibility of banknote jam has been conveyed will be described with reference to FIGS.
FIG. 8 is an explanatory view showing a state when the folded paper money passes through the gap between the protruding portions, and FIG. 9 is an explanatory view showing a detection state by the arrival detection sensor of the folded paper money in the skew state.
As shown in FIG. 8, banknotes P formed with left-right asymmetrical folding folds as shown in FIG. 7, which are fed out from the deposit / withdrawal port 2, are provided on the first and second transport guides 18a and 18b, respectively. When the ridges 30 are guided by the upstream inclined surface 23a of the protruding portion 23 and pass through the gap between the upper surfaces 24, the folds 30 are respectively opposed to the spaces narrowed by the upper and lower protruding portions 23 in FIG. The sheet is conveyed downstream while being subjected to conveyance resistance by rubbing the upper surface 24.

  At this time, in the case of a left-right asymmetric folded paper money, the left and right transport resistances are different, for example, when the transport resistance with the right protrusion 23 is large and the left transport resistance is small, as shown in FIG. Thus, the conveyance speed on the right side is slowed down or stopped, but the left side proceeds at a normal speed, so that the banknote P rotates in the direction of arrow E around the right protrusion 23 and the banknote P is skewed. The arrival front sensor 26 detects the arrival of the front end on the left side of the bill P.

When the time difference of arrival times detected by the arrival detection sensors 26 provided downstream of the left and right protrusions 23 is equal to or greater than a predetermined time difference, the banknote P having a strong conveyance resistance such as a folded paper bill is detected. Can do.
As described above, the feeding portion 12 of this embodiment has the pickup roller 13, the feeding roller 15, and the guide roller 17 arranged at the center in the direction perpendicular to the feeding direction, and the protruding portion 23 is located on both the left and right sides of these conveying members. As shown in FIG. 8, it receives a relatively strong conveyance resistance on either the left or right side as shown in FIG. It is considered to increase the sensitivity of detection by causing motion.

  In the above description, an example in which only the right side of the bill P to be fed is delayed has been described, but the arrival of the bill P is detected by the left and right arrival detection sensors 26 even when the conveyance speed has dropped or stopped on both the left and right sides. By monitoring the time and detecting that the arrival time of the unfolded banknote P that smoothly passes through the protrusion 23 is detected, it is possible to detect that the folded banknote has been conveyed.

When the feeding of the folded paper money is detected as described above, the paper money P that is in a badly transported state is returned to the deposit / withdrawal port 2 in order to request the customer to correct the deformation or re-insert the stock. .
That is, the banknote presser 14 is retracted in a direction in which the pressure on the pickup roller 13 is loosened, and the feeding roller 15 and the guide roller 17 are rotated in the reverse direction. At this time, as shown in FIG. 9, by setting the installation position of the arrival detection sensor 26 in the feeding direction to be shorter than the length in the feeding direction of one banknote P from the bottom surface of the deposit / withdrawal port 2, The bill P can be returned to the deposit / withdrawal port 2 while the back surface of the end overlaps the front surface of the uppermost bill P of the bill P remaining in the deposit / withdrawal port 2. Therefore, it is possible to perform an orderly return operation without causing banknote jam.

  As explained in detail above, in the present embodiment, the feeding portion that feeds the banknote P from the deposit / withdrawal port that receives the banknote P is provided with a feeding roller that can rotate forward and reverse, and the fed banknote P is guided from both the front and back sides. Protrusion is provided on the downstream side of the feeding roller of the pair of transport guides, and the folds or folds of the folded bills pass through the protrusion while passing through the transport resistance, and downstream of the protrusion. Since the arrival time of the banknote P is detected by the installed arrival detection sensor, even if it is a folded paper banknote that is difficult to detect, the conveyance resistance when the banknote P passes through the protruding part at the time of feeding is used. When this is detected, the feeding roller can be reversed to return the banknote P to the deposit / withdrawal port, and the folded paper banknote with the possibility of banknote jam can be returned to the customer. Correct the trap and re-throw Effect that only the bill P in a good state can be transported downstream of the feeding portion, and a deposited bill handling mechanism with less device down and reduced obstacles such as bill jam can be provided. Is obtained.

  In the present embodiment, as shown in FIG. 2, the protruding portion 23 is described as being disposed so as to face the inside of the pair of conveyance guides 18, but the present invention is not limited to this. The same effects can be obtained in the following embodiments.

FIG. 10 is an explanatory view showing the side of the deposited banknote handling mechanism of the second embodiment.
In addition, the same part as the said Example 1 attaches | subjects the same code | symbol, and abbreviate | omits the description.
The transport surface 19a of the first transport guide 18a of the present embodiment is formed on the concave curved surface described in the switching blade 11 of the first embodiment in which the surface facing the feed roller 15 is formed so as to cover the feed roller 15. The upstream inclined surface 23a and the downstream inclined surface 23b are formed on the conveying surface 19a, which is a concave curved surface, on the downstream side of the clamping portion formed by the feeding roller 15 and the gate roller 16, as in the first embodiment. A truncated pyramid-shaped protrusion 23 is provided.

The arrangement of the protrusions 23 in the direction perpendicular to the feeding direction, that is, in the left-right direction is the same as that in the first embodiment, but the protrusions 23 on the second conveyance guide 18b side and the guide rollers 17 are omitted.
Further, the position of the arrival detection sensor 26 is arranged at the same position as in the first embodiment on the downstream side along the conveyance line of the protruding portion 23 formed in the first conveyance guide 18a.

  In the above configuration, when the folded bill is fed from the deposit / withdrawal port 2, the front end of the bill P fed out as shown in FIG. 10 is guided to the conveying surface 19a having a concave curved surface, and the protruding portion 23, and the front end of the bent mountain 30 collides with the upstream slope 23a of the protruding portion 23 so as to get over the protruding portion 23 and be conveyed downstream. However, at this time, the conveyance resistance is caused by the bending resistance due to the sudden change of direction. Is added to the bill. In this case, the bending resistance increases as the banknote P has a sharp bend 30 as shown in FIG.

  An unfolded flat banknote P also collides with the protrusion 23 in the same manner, but the conveyance resistance due to bending is relatively small. That is, the upstream slope 23a of the protrusion 23 is formed as a gentle slope so as to minimize the transport resistance of the flat bill P without folding, and the transport surface 19b of the second transport guide 18b from the upper surface 24 of the protrusion 23. Similar to the case described in the first embodiment, the distance indicated by L in FIG. 10 is set to a value that provides a sufficient conveyance resistance when the folded paper currency passes as in the case of the first embodiment. Can be performed.

  As described above, in the present embodiment, a pair that feeds the banknote P from the front and back sides of the feeding section that feeds the banknote P from the deposit / withdrawal port that receives the banknote P and includes a feeding roller that can rotate forward and backward. A concave curved surface formed so as to cover the feeding roller is formed on the conveyance surface of the conveyance guide on the side facing the feeding roller of the conveyance guide, and a protrusion is provided on the concave curved surface, Since the folded valley portion passes over the protruding portion while receiving the conveyance resistance due to the bending resistance, the arrival detection sensor installed downstream of the protruding portion detects the arrival time of the bill P. The same effect as in Example 1 can be obtained.

FIG. 11 is an explanatory view showing the side of the deposited banknote handling mechanism of the third embodiment.
In addition, the same part as the said Example 1 attaches | subjects the same code | symbol, and abbreviate | omits the description.
The projecting portion 23 of the present embodiment is installed with its position shifted in the feeding direction, and the projecting portion 23 provided on the transport surface 19a of the first transport guide 18a is the transport surface 19b of the second transport guide 18b. It is arrange | positioned upstream from the protrusion part 23 provided in this.

Further, the position of the arrival detection sensor 26 is arranged at the same position as in the first embodiment on the downstream side along the conveyance line of the protruding portion 23 formed in the second conveyance guide 18b.
According to said structure, compared with the case where the upper surface 24 of the protrusion part 23 is made to oppose with the 1st and 2nd conveyance guides 18a and 18b shown in Example 1, the position of the extension direction of the protrusion part 23 is provided. By shifting the gap, the gap between the conveyance surfaces 19a and 19b is not suddenly narrowed by the gap between the opposed upper surfaces 24, and the concern that the sensitivity of detection based on the conveyance resistance is excessively increased is eliminated. It is possible to reliably detect a folded bill while avoiding various fluctuations.

  Even in such a configuration, the same effects as those of the first embodiment can be obtained.
