Description

  The present invention relates to an improvement of a banknote handling apparatus equipped in a banknote handling apparatus such as various vending machines having a function of depositing banknotes, a depositing / dispensing apparatus, a change machine, etc. The present invention relates to a bill processing device, a bill handling device, and a lid member opening detection method capable of realizing the function of detecting whether or not a lid member is opened at low cost.

Banknote handling devices such as various vending machines, deposit / withdrawal machines, money changers, and interbank machines used in pachinko amusement halls determine the authenticity and denomination of deposited banknotes, store them in banknote storage, etc. The banknote processing apparatus which performs this process is provided.
FIG. 5 is a schematic diagram showing an example of the arrangement of various sensors provided in the banknote introduction transport path of the conventional banknote processing apparatus. The banknote processing apparatus includes a conveyance member (not shown) such as a conveyance belt that conveys a banknote inserted from the banknote insertion slot 100 into the apparatus along the introduction conveyance path 101, and detects whether or not a banknote is inserted in the banknote insertion slot 100. And an identification sensor 106 that determines the authenticity and denomination of the banknote along the introduction conveyance path 101, and an open / close detection sensor 107 that detects whether the lid member is opened or closed. Further, the banknote handling apparatus includes an apparatus main body 110 having a conveying member on the upper surface, and a lid member 115 that is pivotally supported by an opening / closing shaft 115a provided at one end of the upper surface of the apparatus main body so as to be opened and closed in the vertical direction. Yes. The insertion sensor 105 and the identification sensor 106 are both transmissive sensors, and the light emitting elements 105a and 106a and the light receiving elements 105b and 106b are disposed on the apparatus main body 110 side and the lid member 115 side, respectively. Further, an open / close detection sensor 107 for detecting whether the lid member 115 is opened or closed is disposed on the downstream side of the identification sensor 106. The open / close detection sensor 107 includes a photo interrupter 107a disposed on the lid member 111 side and an apparatus main body. It is comprised from the light-shielding piece 107b arrange | positioned at 110 side. When the insertion sensor 105 is turned on by inserting a bill from the insertion slot 100, a control means (not shown) drives a motor that drives the transport member to transport the bill along the introduction transport path into the apparatus. Further, the control means determines the open / closed state of the lid member 115 based on the detection signal from the open / close detection sensor 107, and takes safety measures such as stopping the driving of the motor that drives the transport member when detecting the opening.

In the conventional banknote handling apparatus, the installation of the opening / closing detection sensor 107 increases the cost, but the opening / closing detection sensor 107 is necessary to prevent the conveyance member from being driven with the lid member opened.
That is, if the open / close detection sensor 107 is not provided, the insertion sensor 105 is first turned on and then the identification sensor 106 is turned on in the process of opening the lid member 115. The change of the sensors 105 and 106 to the ON state at this time indicates that the bills inserted from the insertion slot 100 when the lid member is closed turn on the sensors when the insertion sensor 105 and the identification sensor 106 are sequentially turned ON. There is no change and no change, and the control means cannot distinguish whether the cover member 115 is opened or a bill is inserted only by the detection signals from the sensors 105 and 106. In the case where the sensors 105 and 106 are switched to the ON state in accordance with the receipt of the banknote, it is necessary to continue driving the conveying member, while when the lid member is opened, it is necessary to stop driving the motor. Therefore, the open / close detection sensor 107 is indispensable.
However, as described above, since the open / close detection sensor 107 increases the cost, development of a device configuration that detects the opening of the lid member at low cost has been conventionally required.
Japanese Unexamined Patent Application Publication No. 2007-94807 discloses a bill discriminating apparatus that can also perform opening / closing detection of a lid using a bill detector without providing a dedicated sensor for detecting opening / closing of the lid. . This banknote identification apparatus performs opening / closing detection by patterning the light emission level of a banknote detection unit composed of a transmissive sensor based on the strength of the level.
However, it is clear that the cost is increased in order to realize a software configuration for patterning the light emission level of the bill detector.

And the number of pulses of the motor detected by the motor drive state detection means between the time when the insertion sensor is turned on by the inserted bill and the time when the bill identification sensor is turned on next, When the number of pulses is equal to or less than a predetermined value N, it is determined that the lid member is opened.
Each detection from the insertion sensor and the banknote identification sensor without providing a dedicated detection means for detecting the opening of the lid member, and without patterning the light emission level of the banknote detection section, which is obvious to bring about an increase in cost. It is possible to reliably detect the opening of the lid member based only on the signal.

A bill handling apparatus according to a second aspect of the present invention includes the banknote handling apparatus according to the first aspect.
According to a third aspect of the present invention, there is provided a lid member opening detection method comprising: a main body provided with a conveying member; a lid member pivotally supported to open and close the conveying member; and the lid in a closed state. A bill insertion slot formed between the member and the apparatus main body, an introduction conveyance path for conveying a bill inserted from the bill insertion slot into the apparatus, and the conveyance member provided in the introduction conveyance path are driven. A motor, motor driving state detecting means for detecting the driving state of the motor as the number of pulses, and a light emitting element and a light receiving element which are arranged opposite to each other on the lid member side and the apparatus main body side in the vicinity of the bill insertion slot.

The detected number of pulses of the motor and the number of pulses of the motor detected by the motor drive state detection means between the time when the insertion sensor is turned on by the inserted bill and the time when the bill identification sensor is turned on next time. And when the number of pulses of the former is equal to or less than a predetermined value N, it is determined that the lid member is opened.

  The banknote handling apparatus according to the present invention includes the number of motor pulses detected by the motor driving state detection means between the time when the insertion sensor is turned on by opening the lid member and the time when the banknote identification sensor is turned on. The number of pulses of the former is determined by comparing the number of pulses of the motor detected by the motor drive state detection means between the time when the insertion sensor is turned on by the inserted bill and the time when the bill identification sensor is turned on. Since it is determined that the lid member is opened when the value is N or less, a dedicated opening / closing detection sensor is used to determine whether the lid member forming the insertion port and the introduction conveyance path is opened with the apparatus main body. It can be detected at low cost without using it.

Hereinafter, the banknote processing apparatus (opening detection method of a cover member) of this invention is demonstrated in detail by embodiment shown in drawing.
FIG. 1A is an external perspective view of a banknote handling apparatus according to an embodiment of the present invention, FIG. 2A is a schematic diagram showing the internal configuration of the banknote handling apparatus, and FIG. 1B is a motor and a motor. FIG. 3A is a configuration explanatory diagram of a driving state detection unit, FIG. 3A is a timing chart showing the operation timing of each sensor when a bill is inserted and motor pulses output from the motor driving state detection unit, and FIG. FIG. 4 is a timing chart showing the operation timing of each sensor and the motor pulse output from the motor drive state detection means in the member opening operation process, and FIG. 4 is a flowchart showing each control procedure in the closed state and open state of the lid member.

This banknote processing apparatus 1 is equipped, for example, in a machine between pachinko machines, and has a configuration for storing various banknotes inserted from an insertion port by a user in an internal banknote storage in a stacked state. .
The banknote handling apparatus 1 is vertically moved by an apparatus main body 2 having a conveying member 3 such as a conveying belt on the upper surface, and a rotating shaft 6 provided at one end of the apparatus upper surface so as to open and close the upper surface of the apparatus including the conveying member 3. The lid member 5 that is pivotally supported so as to be opened and closed, the bill insertion slot 10 formed between the lid member 5 in the closed state and the apparatus main body 2, and the banknote S inserted from the bill insertion slot 10 into the apparatus. An introduction conveyance path 15 to convey, a banknote storage 16 that receives a banknote conveyed by the introduction conveyance path 15, a motor 20 that drives the conveyance member 3 provided in the introduction conveyance path 15, and a driving state (rotation) of the motor 20 Number) as a number of pulses, and for detecting bill insertion comprising a light-emitting element 25a and a light-receiving element 25b arranged in opposition to the lid member side and the apparatus main body side in the vicinity of the bill insertion slot 2. The insertion sensor 25, the banknote identification sensor 30 including the light emitting element 30a and the light receiving element 30b arranged to face each other on the lid member 5 side and the apparatus main body 2 side at the downstream side of the insertion sensor 25, and the insertion sensor 25 are turned on. Control means 40 for controlling the start of driving of the motor 20 at the same time, and for determining whether the lid member 5 is opened or closed (whether open or not) based on detection signals from the sensors 25 and 30. Yes.

When the banknote S is inserted from the banknote insertion slot 2 with one end in the longitudinal direction at the head, and the insertion sensor 25 detects the insertion of the banknote and outputs an insertion detection signal to the control means 40, the control means 40 drives the motor 20. Then, the driving of the conveying member 3 is started, and the bill is conveyed along the introduction conveying path 15. This bill is judged by the bill identifying sensor 30 as to the denomination and authenticity, and is stored in the bill storage 16 when it is a genuine bill.
While the lid member 5 is closed, the detection light emitted from the light emitting elements 25a and 30a constituting the sensors 25 and 30 and the light receiving portions of the light receiving elements 25b and 30b are close to each other, and the mutual light Since the axes coincide with each other, each light receiving element normally detects detection light. However, when the lid member 5 is opened by a predetermined angle or more, the light emitting element constituting the insertion sensor 25 on the side close to the bill insertion slot 2. As the distance between the light receiving element 25b increases and the optical axis is displaced, the light receiving level of the light receiving element 25b is lowered and turned on as in the bill detection. On the other hand, when the opening angle of the lid member 5 is further expanded, the positional relationship between the light emitting element 30a and the light receiving element 30b constituting the banknote identification sensor 30 located on the downstream side is shifted and turned on.
The motor drive state detection means 21 detects a pulse plate 22a whose axis is fixed to the output shaft 20a of the motor 20, and a photo interrupter 22b that detects slits formed at a predetermined pitch along the circumferential direction of the pulse plate 22a. And outputs the rotation amount (rotation number) of the motor to the control means 40 as a pulse number.

The control means 40 is in a motor-driven state between the time when the insertion sensor 25 is turned on by the lid member 5 being opened as shown by the broken line in FIG. The number of pulses of the motor 20 detected by the detection means 21 (FIG. 3 (a)) and the motor drive state between the time when the insertion sensor 25 is turned on by the inserted bill and the time when the bill recognition sensor 30 is turned on. The number of pulses of the motor 20 detected by the detection means 21 (FIG. 3B) is compared, and if the former number of pulses is equal to or less than the predetermined value N, it is determined that the lid member 5 has been opened.
According to the inventor's experiment, the number of pulses NB when the lid member was opened was ½ or less of the number of pulses NA due to the passage of bills when the lid member was closed.
This will be further explained based on the flowchart of FIG. 4. In the opening operation process of the lid member 5, first, as shown in step 1, the insertion sensor 25 is in an on state (the same state as when the insertion sensor 25 detects the insertion of a bill). become. When the insertion sensor 25 is turned on, the control means 40 starts driving (forward rotation) of the motor 20, thereby starting to output a pulse signal from the motor driving state detection means 21 (step 2).

Next, an ON signal is output from the banknote identification sensor 30 when the distance between the light emitting element 30a and the light receiving element 30b constituting the banknote identification sensor 30 is widened and the optical axes of each other are shifted (step 3).
The control means 40 uses the time (number of pulses NA) required from when the insertion sensor 25 is turned on when the bill is inserted to when the bill identification sensor 30 is turned on, and for the bill identification after the insertion sensor 25 is turned on when the lid member is opened. The time required for the sensor 30 to turn on (pulse number NB) is compared (step 4), the former pulse number NA> the latter pulse number NB, and the latter pulse number NB is equal to or less than the predetermined value N. In this case, it is determined that the lid member 5 is opened.
As described above, since the period from when the insertion sensor 25 is turned on to when the bill identification sensor 30 is turned on in the process of opening the lid member 5 is a very short time (see FIG. 3B), The number of motor pulses generated is detected in the normal bill insertion operation when the lid member is closed and the leading edge of the bill conveyed after the start of driving the motor reaches the bill recognition sensor 30 and the bill is identified. Compared to the number of motor pulses (FIG. 3A) generated until the sensor for use is turned on, the number of pulses is clearly smaller. For this reason, the case where the cover member 5 is opened and the case where the cover member 5 is in a closed state and a bill is inserted can be clearly distinguished.

When it is determined that the lid member 5 has been opened, the control means 40 performs lid opening detection processing such as stopping the motor (step 6). On the other hand, when it is determined that the lid member is closed, that is, it is a normal bill insertion, the identification sample by the bill identifying sensor 30 is started (step 5).
According to the present invention, the insertion sensor and the banknote identification can be performed without providing a dedicated detection means for detecting the opening of the lid member and without patterning the light emission level of the banknote detection section that is apparent to increase the cost. It is possible to reliably detect the opening of the lid member based only on each detection signal from the sensor for use.
In addition, the banknote processing apparatus 1 of this invention can be applied to banknote handling apparatuses, such as various vending machines, depositing / withdrawing apparatuses, a change machine, and the machine between machines used in a pachinko game hall.
