Description

[Detailed Description of the Invention] [Field of the Invention] The present invention relates to a paper sheet discharging device, and particularly to a banknote discharging machine used in a teller device of a financial institution such as an automatic teller machine.

[Prior art and its problems]

(Prior Art) In conventional paper sheet discharging devices, there is a demand for a single discharging device capable of discharging different types of paper sheets. For example, a banknote dispensing machine installed in a financial institution or the like needs to discharge a plurality of types of banknotes. Such a bill dispensing machine is equipped with a plurality of bill cartridges classified for each denomination, and
2. Description of the Related Art A bill discharging device is known that discharges bills of desired denominations from respective bill cartridges. Such a banknote discharging device is equipped with a detection sensor that detects whether or not a banknote cartridge is attached, and in addition to these sensors, a discharge sensor that indicates that a banknote has been discharged from each cartridge and a sensor along the banknote passage path are installed. A large number of sensors are provided to check the passage of banknotes.

(Problems to be Solved by the Invention) In such a conventional banknote dispensing machine, each cartridge requires at least two sensors for detecting attachment of the cartridge and passage of a banknote. Therefore, since a large number of sensors are used in the banknote dispensing machine, the structure is complicated, and assembly and maintenance and inspection are time-consuming. Furthermore, since the number of sensors increases, it is difficult to reduce the cost of the bill dispensing machine.

[Technical issues]

The present invention was developed in view of the shortcomings of the conventional paper sheet discharging device, and the present invention uses a sensor that detects the presence or absence of a cartridge and a sensor that detects the passage of paper sheets for each cartridge. Therefore, the technical challenge is to reduce the number of sensors.

[Structure and effect of the idea]

(Means for Solving the Problems) The paper sheet discharging device according to the present invention includes a plurality of cartridges attached to the main body and holding paper sheets of each type, and a plurality of cartridges arranged in the vicinity of the paper sheet entrance/exit of each cartridge. A photoelectric switch is provided at each of the photoelectric switches and has a pair of light emitters and receivers facing each other across the paper path, and is movably held between the light path of the light emitter and receiver of each photoelectric switch to keep the photoelectric switch in a light-shielding state. a plurality of sensor covers that are energized so as to be displaced as each cartridge is attached to set the respective photoelectric switches in a light-receiving state; a sheet discharge means that discharges sheets of paper from each cartridge; A mounting detection means detects the mounting of a cartridge by the change of a photoelectric switch from a light-shielding state to a light-receiving state, and a paper leaf ejection means ejects paper sheets in a state after the mounting detection means detects the mounting of each cartridge. It is characterized by comprising passage detection means for detecting the passage of a paper sheet based on a change in a predetermined time from a light receiving state to a light blocking state of a photoelectric switch attached to each cartridge as the cartridge operates. .

(Function) In the paper sheet discharging device according to the present invention, when the photoelectric switch installed in front of the cartridge is in a light-shielding state, it is determined that the cartridge is not installed. If the cartridge is in this state, it is assumed that the cartridge is installed and processing can proceed. Further, when the cartridge is installed, the photoelectric switch is in a light receiving state, and operates the paper sheet ejecting means to eject paper sheets in response to an external ejection command. At this time, the photoelectric switch is blocked from light for a predetermined period of time by the paper ejected from the cartridge that holds the paper, and this action allows you to judge whether or not the paper has passed correctly. be.

(Effects) Therefore, in the present invention, since one photoelectric switch can be used to check the attachment and detachment of a cartridge and the ejection of a bill, the number of photoelectric switches can be reduced. Therefore, the structure of the paper sheet discharging device can be simplified, and assembly and maintenance and inspection work can be simplified. As a result, it is also possible to reduce the price of the paper sheet discharging device itself.

[Explanation of Examples]

(Configuration of Embodiment) FIG. 1 is a side view of a main part of a banknote dispensing machine showing an embodiment of the present invention. In this figure, four bill cartridges 1, 2, 3, and 4 and a collection box cartridge 5 are installed in a bill dispensing machine while being guided by rails (not shown). The following banknote cartridges 1~
4 will be explained only for banknote cartridge 1. As shown in detail in FIGS. 2a and 2b, a lever 1a is provided at the tip of the banknote cartridge 1, and a banknote 1b of a desired denomination is loaded inside the lever 1a between a presser plate 1c and a feeding roller 1d.
The pressing plate 1c always presses the banknote 1b toward the delivery roller 1d by means of a spring (not shown). The feeding roller 1d is provided with a small distance from the opposing fixed roller 1e, and feeds out the banknotes 1b one by one by rotating in the direction shown by the arrow. The fixed roller 1e is held so that it can rotate only in the direction of the arrow, and prevents several bills from being fed out at the same time. 1f and 1g are an out-of-bill forecast sensor and an out-of-bill sensor, respectively, and 1h is a denomination setting switch for setting the denomination of the cartridge.

FIG. 2a is a top view showing the tip of the banknote cartridge 1, and FIG. 2b is a side view thereof. A sensor cover 6 is provided at a position facing the lever 1a and is pressed by the lever 1a. The sensor cover 6 is a flat plate having notches at its corners, and is rotatably held around a shaft 6a. The sensor cover 6 is normally pressed in the direction of arrow A by a spring 11 to the position shown by the solid line where it contacts the stopper 12, and when the banknote cartridge 1 is attached, the sensor cover 6 is pressed against the lever 1a against the elastic force of the spring 11. Rotate in the direction of arrow B to the position shown by the broken line. Here, a sensor S1 is provided, which is a photoelectric switch having a light projector and a light receiver on the upper and lower sides of the sensor cover 6, respectively, and arranged so that the sensor cover 6 blocks light from its optical path. If the banknote cartridge 1 is not installed, the sensor S
The light of S1 is blocked by the sensor cover 6 and enters the on state (light blocking state). When the bill cartridge 1 is attached, the sensor cover 6 rotates and the light hits the sensor S1, and the sensor S1 becomes the off state (light receiving state). becomes.
Further, when the feeding roller 1d is energized and the banknote is discharged from the banknote cartridge 1, the banknote is conveyed through the path 13 shown in FIG. 2b. The light emitter and the light receiver face each other across the path 13, and because they block light when the banknote passes between the sensors S1, the sensor S1 is in an on state (light blocking state) during that time. Sensor S1 can therefore be used as a banknote release sensor and a release counter. Furthermore, when the banknotes are ejected from the banknote cartridge 1 and transported normally, the sensor S1 remains on for approximately a certain period of time;
If a bill gets jammed at the outlet, the on state will continue. Therefore, jamming of banknotes can be detected based on the time during which the sensor S1 is turned on.

There is also a lever 5a at the tip of the collection box cartridge 5.
and a sensor cover 10 are provided, and the sensor S5 is in an on state (light-shielding state) when the collection box cartridge 5 is not attached.
If it is attached, it will be in the off state (light receiving state), and when it is recovered, it will be in the on state (light blocking state) for a certain period of time. Also, passage sensors S6, S7, S8, S9, S1 detect passage of banknotes and jamming of banknotes along the banknote passage route.
0 is set. The thickness detection section 14 detects the thickness of banknotes, and checks if the banknotes are sent in duplicate. The temporary holding section 15 temporarily holds the banknotes until all the banknotes to be ejected at the same time are sent from the conveying means, and when all the banknotes have been conveyed, all the held banknotes are released from the discharge port 16. do. S11 is a release sensor, S12
is the holding sensor. Separator 1 is used for banknotes that are poorly conveyed or that are caught in the conveyance mechanism.
7 and are collected into the collection box cartridge 5 through the collection sensor S5. 18 is a cover sensor composed of a micro switch and the like. A cover 19 that covers the back of all cartridges is attached to this bill ejecting machine. The cover 19 is normally closed and is opened when the bill cartridges 1 to 4 or the collection box cartridge 5 are attached or detached. The cover sensor 18 is connected to this cover 1.
The open/closed state of 9 is detected.

Next, the structure of this banknote dispensing machine will be explained with reference to the block diagram of FIG. Various sensors S1
The outputs of ~S12, 1f~4f, 1g~4g and denomination setting switches 1h~4h are sent to an arithmetic processing unit (hereinafter referred to as CPU) 21 via a reading circuit 20.

Connected to the bill dispensing machine are a terminal controller 26 that gives commands to the bill dispensing machine from the outside via a transmission control circuit 25, and an operation panel 27 that has a keyboard and display means and gives various data such as amount of money to the bill dispensing machine. has been done. The CPU21 is a read-only memory (hereinafter referred to as ROM)
According to the arithmetic processing procedure stored in the random access memory (hereinafter referred to as RAM) 28, the motor of the conveyance system is activated via the motor drive circuit 30 to eject the type and quantity of banknotes temporarily stored in the random access memory (hereinafter referred to as RAM) 29. 31, driving and controlling the fan 32 and driving the clutch 34 via the clutch driving circuit 33;
Controls the rotation of each roller. The feeding rollers 1d to 4d, the fixed rollers 1e to 4e, the motor drive circuit 30, the motor 31, the clutch drive circuit 33, and the clutch 34 in each banknote cartridge 1 to 4,
forms a paper sheet discharging means for discharging paper sheets from the banknote cartridges 1 to 4. As shown in the figure, the RAM 29 is provided with a cartridge table 29a that stores denomination data given from the denomination setting switches 1h to 4h of each banknote cartridge 1 to 4. Here, data indicating that banknote cartridge 1 is loaded with 500 yen bills, banknote cartridge 2 with 1,000 yen bills, banknote cartridge 3 with 5,000 yen bills, and banknote cartridge 4 with 10,000 yen bills is stored. .

(Operation) Next, the operation of the bill dispensing machine of this embodiment will be explained with reference to a flowchart. Numbers indicated using leader lines indicate operation steps of the CPU 21. FIG. 4 is a flowchart showing the operation of the banknote dispensing machine after power is turned on. In this figure, after the power is turned on, a check of the arithmetic and control unit, such as a thumb check, is performed (step 40), and if normal, the clutch, etc. of the bill ejection machine is initialized in step 42, and if there is an error, an error code is displayed. Stop (step 43). If it is normal, the conveying section of the banknote dispensing machine is further operated for a certain period of time (step 44), and banknotes that may remain in each sensor section are collected into the collection box cartridge 5. Subsequently, passage sensors S6 to S10 and release sensor S1
1. Check the holding sensor S12. If there are banknotes left, an error code to that effect is displayed in step 47, and if there are no banknotes, the banknote cartridges 1 to 4 are stored in step 48.
The presence or absence of the collection box cartridge 5 is checked. In this case, the sensors S1 to S5 are used as sensors for determining whether or not the banknote cartridges 1 to 4 and the collection box cartridge 5 are attached to predetermined positions. As shown in Figure 7a and b, the cartridge 1
At time _t1 when the sensors S1 to S4 are attached, the sensors S1 to S4 are attached.
is in the off state. Similarly, when the collection box cartridge 5 is installed, the sensor S5 is turned off. When sensors S1 to S4 are on and sensor S
If 5 is on, banknote cartridges 1 to 4 are selected respectively.
Alternatively, it is determined that the collection box cartridge 5 is not installed, and an error code is displayed to that effect (step 49), and the operation is stopped. Steps 48-5
At 0, the CPU 21 operates as an attachment detection means for detecting attachment of the cartridges 1 to 5. When the sensors S1 to S5 are off, the banknote cartridges 1 to 4 and the collection box cartridge 5 are installed, so the machine enters an idle state. The idle state is a state in which the banknote dispensing machine is checking its status and waiting for a command to dispense the bill.

In step 51, the passing sensors S6 to S1
0. Check the status of release sensor S11 and holding sensor S12. If these are on, the remaining banknotes are displayed as an error code (step 53), and if they are off, the sensors S1 to S5 are further checked (step 54). If these are on, an error code is displayed to indicate that the cartridge or collection box is not attached, as in step 49 (step 56), and if they are off, the presence or absence of a withdrawal command is checked (step 57). If there is no withdrawal command, return to step 51, and continue to step 51 until there is a withdrawal command.
Repeat steps 57 to 57.

FIG. 5 is a flowchart showing the bill discharging operation, and when a withdrawal command is issued, steps 58 and 60 are performed.
At this point, the sensors S6 to S11 and S1 to S5 are checked. If no banknotes remain and the banknote cartridges 1 to 4 and the collection box cartridge 5 are properly installed, one banknote is ejected from the designated banknote cartridge in step 62 and step 64. It is then checked in step 65 whether the banknotes have been successfully ejected from the banknote cartridge. In this case too, the sensor S
1 to S4, and if the on-time is less than the specified value (step 66), as in the operation from time _t2 to _t3 in FIG. The counter is counted up (step 67) and steps 64 to 67 are repeated until the requested amount has been released. Step 69
, the sensors S1 to S4 have passed a specified time,
If the power is turned off at time _t5 as shown in FIG. 7a, it is determined that two bills have been ejected in succession, an error code to that effect is displayed, and the operation is stopped (step 70). . In steps 65-70, the CPU
Reference numeral 21 operates as a passage detection means for detecting passage of banknotes based on the operating time of the sensor. On the other hand, as shown in FIG. 7B, if the on state continues after time _t4 and the switch does not turn off, the state of the cover sensor 18 is checked in step 71. If the cover 19 is open, it is determined that the cartridge has been removed, an error code to that effect is displayed (step 72), and the operation is stopped. On the other hand, if the cover is closed, it is determined that a banknote has become jammed, an error code to that effect is displayed (step 73), and the operation is stopped.

When collecting banknotes, the banknotes are collected from the temporary holding section 15 in step 74, as shown in the flowchart of FIG. and passing sensor S
9. The collection sensor S5 confirms the passage of banknotes. If the sensors S9 and S5 turn on and off in step 76, passage can be confirmed, and if they do not change from on to off, it is assumed that the banknotes have become jammed during collection, and an error code is displayed to that effect. In this case, the collection sensor S5 is used as a banknote passage sensor. In steps 75-77
The CPU 21 operates as a passage detection means for detecting passage of banknotes.

Although the present embodiment has been described using a bill dispensing machine as an example, the present invention is not limited to bill dispensing devices, and can be applied to various paper dispensing devices such as copying machines.
