Ml is a motor for the above-mentioned identification conveyance (hereinafter referred to as a first conveyance motor), 5 is a second conveyance means for guiding the banknotes to the first escrow section 4, and Ml is a motor for driving the 2117th conveyance means 5. (hereinafter referred to as a second conveyance motor), 6 is arranged in parallel with the first escrow section 4, and is capable of transferring and storing banknotes temporarily reserved in the first escrow section 4 from the first escrow section 4. Part of the stacker. Further, 7 is a third conveying means provided downstream of the second conveying means 6, formerly its drive motor (hereinafter referred to as the third conveying motor), 8 is a second escro section, and 9 is a second escro section 8. This is a second stacker section into which banknotes temporarily reserved can be transferred from the second escrow section 8 and stored therein.

Furthermore, FIG. 7A shows the configuration of the first escro section 4 and the first stacker part 6, where 10 is the first
The banknotes held in the escrow section 4, IOA, are the banknote bundle 1 held in the accumulated state in the first stacker part 6.
1 is a banknote holding member provided in the storage section 6A of the first stacker part 6, and 12 is a receiving plate that holds the banknote bundle 10A between the banknote bundle 10A and the holding member 11 by means of a spring 13.

In the banknote validating machine and its conveyance device configured in this way, the inserted banknotes are temporarily held in the first escrow section 4. However, if the banknote is a low denomination banknote, when the next banknote is inserted, it is stored in the storage section 68 by the storage operation in the first stacker part 6 described above, and
If the banknote is a high-value banknote, it is further transferred to the second escrow section 8 shown in FIG. 6, after which the next inserted banknote is taken in and guided to the first escrow section 4.

[Problem that the invention seeks to solve]

However, in the conventional paper sheet conveyance system as described above, as shown in FIGS. 8A and 8B, when a banknote is first inserted at time T, the first conveyance motor Ml The bill is conveyed to the first escrow section 4 in cooperation with the second I2 feed motor M2, during which it is identified, and a genuine bill signal VEND is output while it is being held, as shown in (C). Thus, if this preceding banknote is, for example, a low-denomination banknote, and the next succeeding banknote is inserted at time T2, the stacker motor 15 is driven as shown in (D), and the low-denomination banknote is inserted into the first banknote.
While being guided to the stacker part 6, the first transport motor M
l is not driven, and the first transport motor M1 is driven for the first time at the time T when the storage operation is completed, and this second banknote is transferred to the first banknote.
You will be guided to the escrow section 4.

The reason is that if we are currently storing the first sheet at the time T.
When the identification conveyance operation by the first conveyance means 3 is performed between 2 and T, the first escrow section 4 stores the banknotes in the first stacker part 6 during that time, as shown in FIGS. 7B to 7D. This is because the normal transport operation from the first escro section 4 onwards cannot be carried out due to the interruption of the operation.

For this reason, even if a later banknote is inserted, the first escrow section 4
The taking-in operation for banknote identification is not performed until the banknote storing operation in step 1 is completed, and there is a disadvantage that the user is forced to wait for that much wasted time.

The purpose of the present invention is to focus on the above-mentioned conventional problems, and to solve them, when a second or subsequent banknote is inserted,
A control system for a paper sheet conveying device that, when a banknote is detected, immediately takes in and identifies the banknote, and starts storing the banknote in a portion of the first stacker, thereby shortening the interval time between banknote insertion by the user. The goal is to propose the following.

[Means for solving problems]

In order to achieve such an object, the present invention enables paper sheets being conveyed by a conveyance means to be temporarily held in a temporary holding means after being identified by an identification means, and the temporary holding means is capable of storing identified genuine bills. When the preceding sheet is being held in the temporary holding means, the stacker starts the storing operation of the preceding sheet at the same time as the conveying means starts conveying the succeeding sheet, and the storing operation starts. This feature is characterized in that the subsequent paper sheets are controlled so as to arrive at the temporary holding means after waiting for the end of the process.

(Function) According to the present invention, when the next banknote is inserted while the first banknote is held in the first escrow section, the banknote is identified while being conveyed, and the first banknote is simultaneously inserted. The stacker performs a storage operation to store the items in the storage section. If the identification operation for the subsequent banknote is completed before the storage operation for the first banknote is completed, the conveyance of the subsequent banknote is temporarily stopped, and the system waits for the storage operation for the preceding banknote to be completed. This method eliminates the holding time for receiving subsequent banknotes compared to conventional methods.
Accordingly, it is possible to provide the user with the convenience of shortening the waiting time.

〔Example〕

Embodiments of the present invention will be described in detail and specifically below based on the drawings.

FIG. 1 and FIG. 2 show the configuration of a banknote recognition machine and its conveyance device that implement the system according to the present invention.

Also, at time T4, the first
When the stacker motor 15A has finished storing the first banknote, the first transport motor M1 transports the subsequent banknote by 1!, as shown by the broken line in (A). Continuing,
Further, at time T5, the subsequent banknote is guided to the first escrow section 4 and held in cooperation with the second conveyance motor M2, and then a genuine banknote signal is output.

Next, FIG. 5 shows the procedure of the series of control operations described above. First, in step S1, it is determined whether or not a banknote has been inserted, and after waiting for the insertion, in the next step S2, it is determined whether or not a preceding banknote is being held in the first escrow section 4. If it is determined that the bill is on hold, the process proceeds to step S3, where the first conveyance motor M1 is rotated forward to carry out the conveyance of the subsequent banknote, and the first stacker motor 15^ is driven to carry out the preceding banknote. Starts the banknote storage operation. Then, in the next step S4, the banknote is identified, and in step S5 it is determined whether or not it is a genuine banknote.If it is determined that it is not a genuine banknote, the process branches to step S6 and a series of banknote return operations are performed. I do.

If it is determined in step S5 that the banknote is a genuine banknote, it is determined in step S7 whether or not the banknote has been detected by the position detection sensor 20, and after waiting for the detection, the process proceeds to the next step S8 and the first stage is reached. Tsuka motor 15
It is determined whether the storage operation by A has been completed. Here, if it is determined that it has been completed, in step S9, the first conveyance motor Ml is continuously driven in the normal rotation, and the second conveyance motor M2 is cooperated to guide the banknotes to the first escrow section 4,
In the next step 510, the motors M1 and M2 are stopped, and in step 511, a genuine bill signal is output.

On the other hand, if it is determined in step S2 that the preceding bill is not on hold, the process branches to step S12, the first transport motor Ml is driven, and the operations from step 54 onwards are performed. If it is determined in step S8 that the storage operation in the first stacker part 6 is not completed, the first transport motor M1 is temporarily stopped in step S13, and the first stacker motor M1 is stopped in step S14. It is determined whether the normal rotation operation of 15A has timed out. If the time has elapsed here, it is determined that there is a failure and the process proceeds to step 515 to perform abnormality processing. If it is determined that the time has not exceeded, the process returns to step S8 and waits for the storage operation in the first stacker part 6 to be completed, and the operations from step 59 onwards are performed.

〔Effect of the invention〕

As explained above, according to the present invention, after the paper sheets being conveyed by the conveyance means are identified by the identification means, they can be temporarily stored in the escrow section, and the escro section is a stacker in which the identified genuine bills can be stored. When the preceding sheet is being held in the escrow section, the stacker starts the storing operation of the preceding sheet at the same time as the conveying means starts transporting the following sheet, and waits for the end of the storing operation. Since the subsequent paper sheets are controlled to reach the escrow section, the insertion interval time when paper sheets are continuously inserted can be shortened, and it is possible to improve the usability for the user. can.
