Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a banknote validating machine used in automatic vending machines, currency exchange machines, etc., and particularly relates to a banknote validating machine equipped with a mechanism to prevent banknotes from being pulled out.

[Prior Art] Generally, a banknote validating machine that identifies the authenticity of banknotes is
A banknote running path formed between an upper running board and a lower running board, and an upper roller and a lower roller that sandwich and transport the banknotes supplied to the running path from above and below;
and an identification sensor installed in the middle of the banknote running path to identify the authenticity of the banknote conveyed by each roller, and when the banknote is determined to be genuine by the recognition sensor, an external interface is sent to the banknote. It is now possible to supply products by outputting an identification signal.

However, in the case of such a banknote validating machine,
Banknotes may be withdrawn due to fraudulent activity. For this reason, the conventional banknote validator has a structure in which a pull-out prevention lever is provided on either the upper running plate or the lower running plate, located in the middle of the bill running path.

[Problem that the invention attempts to solve]

However, since the withdrawal prevention lever according to the above-mentioned conventional technology is provided at only one location in the middle of the banknote travel path, there is a problem that fraudulent acts may be possible at the time when the identification signal is output from the identification sensor. .

The present invention was developed in view of these problems, and includes disposing pull-out prevention levers that can open and close the banknote travel path at a predetermined distance in the travel direction, respectively, on the upper and lower sides of the banknote travel path. By arranging each of the pull-out prevention levers, the rotation direction of each pull-out prevention lever is reversed, so that even if one of the pull-out prevention levers is passed in the opposite direction, the other pull-out prevention lever will not be rotated. Therefore, it is an object of the present invention to provide a banknote validator that can prevent banknotes from being pulled out and improve the reliability of measures to prevent banknotes from being pulled out.

[Means for solving problems]

In order to solve the above problems, the configuration adopted by the present invention includes a banknote running path formed between an upper running board and a lower running board, and a banknote feeding path that is sandwiched between upper and lower sides of the banknote running path. In a banknote validating machine comprising an upper roller and a lower roller to be conveyed, and an identification sensor provided in the middle of the banknote running path to identify the authenticity of the banknotes conveyed by the respective rollers, the banknote running path is An upper pull-out prevention lever is located on the upper travel plate, and a lower pull-out prevention lever is located on the lower travel plate, located downstream of the identification sensor in the travel direction, and spaced apart from each other by a predetermined distance in the travel direction. springs are provided in the upper pull-out prevention lever and the lower pull-out prevention lever so that the banknote travel path is closed at all times and that the banknote travel path is opened only when the banknote is passed; A member is provided, and a passage detection sensor is provided on one or both of the upper withdrawal prevention lever and the lower withdrawal prevention lever, and the identification sensor determines that the bill is genuine, and the passage detection sensor determines that the bill is genuine. After confirming passage, it is configured to output an identification signal to the outside.

[Effect]

With the above configuration, when a banknote moves through the banknote running path and comes into contact with the upper pull-out prevention lever and the lower pull-out prevention lever, each lever opens the banknote run path against the spring member, allowing the banknote to pass. When a banknote passes through each withdrawal prevention lever, each lever is biased by a spring member to close the banknote travel path and prevent the banknote from being pulled out.

Further, the passage detection sensor detects when a banknote passes through either one or both of the upper withdrawal prevention lever and the lower withdrawal prevention lever. Then, after the identification sensor determines that the banknote is genuine and the passage detection sensor confirms that the banknote has passed, an identification signal is output to the outside.

Therefore, when the banknote 10 passes through the banknote running path 3, the lever piece 26B of the lower withdrawal prevention lever 26 rotates in the clockwise direction C' against the compression spring 26C, thereby preventing the banknote 10 from passing. However, when an attempt is made to pull out the passed banknote 10, the lever piece 26B locks the banknote 10 and prevents the banknote 10 from being pulled out.

Reference numeral 27 indicates a passage detection sensor that outputs a bill passage signal when the lever piece 26B rotates in the clockwise direction C'. The passage detection sensor 27 is connected to each identification sensor 1 along with the passage detection sensor 25 described above.
As a result of the determinations in steps 1 to 14, when a bill is determined to be a genuine bill and a bill passage signal is output from these passage detection sensors 25 and 27, the bill is configured to output an identification signal to the external interface. ing.

The present embodiment is configured as described above, and its operation will be described next.

First, when the banknote 10 is inserted into the banknote running path 3, the upper rollers 4, 5, 6 and the lower rollers 7, 8, 9 work together to run the banknote 10 in the running direction A. Authenticity and denomination are sequentially identified by sensors 11 to 14. If it is a counterfeit ticket, it will be returned in the return direction A'.

On the other hand, if it is a genuine bill, it reaches the upper withdrawal prevention lever 23 located downstream of the identification sensors 13 and 14, and rotates the lever piece 23B in the counterclockwise direction B'.
It passes through the position of the lever piece 23B. At this time,
A bill passage signal is output from the passage detection sensor 25 by the detection lever piece 24 . In addition, 10 banknotes
travels and reaches the lower pull-out prevention lever 26,

A passage detection sensor 25 is provided which outputs a bill passage signal when the detection lever piece 24 provided at A is rotated in the opening direction (counterclockwise direction B'), and the lever piece 26B of the lower withdrawal prevention lever 26 is A passage detection sensor 27 is provided that outputs a bill passage signal when the passage detects sensor 27 rotates in the opening direction (clockwise direction C'). Since the configuration is configured to output 10 identification signals, each pull-out prevention lever 23,
26, it is possible to output a signal indicating that the banknote is a genuine banknote while preventing the banknote 10 from being pulled out, thereby effectively eliminating fraud.

Furthermore, as a result of this configuration, since the bill identification signal is output from each passage detection sensor 25, 27 almost simultaneously with the operation of each withdrawal prevention lever 23, 26 in the opening direction, a person who does not intend to withdraw the bill 10 It is possible to promptly supply products, etc.

Furthermore, each pull-out prevention lever 23, 26
are each compression spring 23C, 26C as a spring member.
Therefore, since the inside of the banknote running path 3 is always closed and the banknote running path 3 is opened when a banknote passes, the spring force of each compression spring 23C, 26C and the banknote 1 are
The bill running path 3 can be reliably opened and closed with only a moving force of 0, and the mechanism can be simplified. As a result,
Compared to the case where an actuator such as an electromagnet is used, wiring work and the like are not required, and not only can manufacturing be performed easily, but also energy saving can be achieved.

In addition, in the above embodiment, each pull-out prevention lever 2
3 and 26 may have the vertical relationship reversed, and each of the pull-out prevention levers 23 and 26 may have the same shape,
Either one of the configurations may be adopted. On the other hand, although the passage detection sensor 25 is actuated by providing the detection lever piece 24 on the upper withdrawal prevention lever 23, the passage detection sensor 25 may be actuated by the lever piece 23B. In addition, a passage detection sensor 2 is provided for each pull-out prevention lever 23, 26.
Although 5 and 27 are provided, it is also possible to provide a structure in which these are provided only on one side.

[Effect of idea]

The present invention has been described in detail above, and includes an upper pull-out prevention lever and a lower pull-out prevention lever on the upper and lower sides of the bill running path, which normally closes the bill running path and opens the bill running path only when the bill passes. Since the levers are provided, the banknotes can be easily passed through the levers to the downstream side in the running direction, and the rotating directions of the levers are opposite to each other.
It is possible to reliably prevent banknotes from being pulled out. Furthermore, since the levers are disposed at a predetermined distance apart in the running direction, it is possible to more effectively prevent the withdrawal of banknotes, thereby increasing the effect of preventing fraud.

Further, a passage detection sensor is provided on either or both of the upper withdrawal prevention lever and the lower withdrawal prevention lever, and after the identification sensor determines that the bill is genuine and the passage detection sensor confirms passage,
Since the identification signal is output to the outside, the banknote cannot be removed after the identification signal of the banknote is output, and fraudulent acts can be reliably excluded. On the other hand, since it is possible to detect the passage of a banknote almost simultaneously with the activation of each withdrawal prevention lever and output an external identification signal indicating that the banknote is a genuine banknote, products, etc. can be promptly supplied to those who do not intend to withdraw the banknote. It can be carried out.

Further, since each pull-out prevention lever is provided with a spring member and the spring member opens and closes each pull-out prevention lever, the pull-out prevention mechanism can be simplified and easily manufactured.
