Utility Model Content

[0003] The main purpose of this invention is to provide a mechanism to prevent multiple card insertions and a self-service terminal device, which aims to reduce malfunctions of the self-service terminal device during the card recycling process.

[0004] To achieve the above objectives, the present invention proposes an anti-multiple card insertion mechanism, which is applied to a self-service terminal device. The self-service terminal device includes a housing and a card dispensing slot located on the housing. The anti-multiple card insertion mechanism includes:

[0005] An outer cover is fixed to the surface of the housing and covers the card retrieval opening. The outer cover and part of the housing enclose an installation space. The outer cover is also provided with a card retrieval slot, which communicates with the installation space and is positioned opposite to the card retrieval opening.

[0006] A door stop switch is provided within the installation space, and the door stop switch can move relative to the housing to open or close the card retrieval port;

[0007] A contact switch is provided within the installation space, with a portion of the contact switch located on the side of the door stop switch near the card slot;

[0008] When a card is inserted into the card slot, the contact switch contacts the card, and the blocking switch opens the card slot according to the contact signal of the contact switch; after the card enters the card slot, the blocking switch closes the card slot.

[0009] In one embodiment of this utility model, the door stop switch includes:

[0010] An electromagnet, with a guide and limiting part, is also provided on the side of the electromagnet;

[0011] A door stop plate, which is rotatably disposed within the installation space, has a limiting section and a door stop section. The limiting section is disposed near the guide limiting part, and the door stop section is disposed near the card retrieval port.

[0012] The electromagnet attracts or releases the gate plate according to the signal of the contact switch, and the guide and limiting part guides and limits the movement of the gate plate so that the gate section moves to below the card retrieval port to open the card retrieval port.

[0013] In one embodiment of this utility model, the gate switch includes a second reset member, which is connected to the gate plate and the housing respectively. When the electromagnet releases the limiting segment, the second reset member drives the gate plate to reset.

[0014] In one embodiment of the present invention, the gate plate further includes a fixed section, the limiting section and the gate section are respectively connected to both ends of the fixed section, and together with the fixed section form a first receiving groove;

[0015] The gate switch also includes a first rotating shaft, the limiting section and the gate section are respectively disposed in the first shaft hole, the first rotating shaft passes through the first shaft hole and is fixed to the housing, the second reset member is sleeved on the surface of the first rotating shaft and accommodated in the first receiving groove, and the two ends of the second reset member elastically abut against the limiting section and the gate section respectively.

[0016] In one embodiment of this utility model, the contact switch includes:

[0017] A signal sensing device includes a sensing structure disposed in the installation space, wherein a sensing groove is formed on the surface of the sensing structure, and a signal transmitter and a signal receiver are disposed on the side of the sensing groove.

[0018] A contact structure is rotatably disposed within the installation space. The contact structure includes a contact element and a signal blocking element. The signal blocking element is connected to the contact element, and one end of the signal blocking element extends into the sensing groove. A portion of the contact element is located on the side of the door stop switch closer to the card retrieval slot.

[0019] The card is inserted into the card slot and abuts against the contact part to drive the contact member to rotate relative to the housing, thereby causing the signal blocking member to move to separate from the sensing slot, so that the signal sensing device can receive the card insertion signal.

[0020] In one embodiment of this utility model, the contact switch further includes a fixing base, the fixing base is fixed to the housing, and the sensing structure is fixed to the surface of the fixing base;

[0021] And / or, the contact structure further includes a fixing member, one end of which is fixed to the housing via a second rotating shaft, and the contact member is connected to the fixing member via a third rotating shaft.

[0022] In one embodiment of this utility model, the contact member includes a first connecting part, a second connecting part, a third connecting part, and a contact part that are bent in sequence. The first connecting part, the second connecting part, and the third connecting part form a second receiving groove. The first connecting part and the third connecting part are respectively provided with a third shaft hole. The third rotating shaft passes through the third shaft hole and is connected to the fixing member. The contact part is located on the side of the door stop switch near the card retrieval groove.

[0023] The contact switch further includes a third reset member, which is sleeved on the surface of the third rotating shaft, and the third reset member also elastically abuts against the first connecting part and the third connecting part;

[0024] The end of the signal blocking component away from the sensing groove is sleeved on the surface of the third rotating shaft;

[0025] When the card separates from the contact part, the third reset member drives the contact member to reset the signal blocking member.

[0026] In one embodiment of this utility model, the contact portion is arranged in an arc shape.

[0027] In one embodiment of this utility model, the side of the contact portion is further bent to form a guide surface.

[0028] This utility model also provides a self-service terminal device, which includes a mechanism to prevent multiple card insertions.

[0029] The anti-multiple card insertion mechanism proposed in this utility model is applied to self-service terminal equipment, specifically during the card receiving state of the self-service terminal equipment. When a card needs to be received, the user inserts a card into the self-service terminal equipment from the external card slot. A card receiving signal is obtained through contact with the card via a contact switch. At this time, the gate switch opens the card receiving slot based on the card receiving signal obtained from the contact switch, allowing the card to enter the internal transmission channel of the self-service terminal equipment through the card receiving slot. Since the card is now fully inside the card receiving slot, but the self-service terminal equipment has not yet completed card retrieval, to prevent the user from inserting another card into the card slot, thus avoiding congestion in the transmission channel near the card receiving slot, the gate switch quickly closes the card receiving slot based on the contact switch signal after the card separates from the contact switch. This prevents the user from inserting multiple cards into the self-service terminal equipment in a short period of time before the card is fully retrieved, thus ensuring the normal operation of the self-service terminal equipment.

[0047] Self-service terminals, with their real-time card issuance and dispensing capabilities, allow users to obtain cards instantly and have been widely used in various settings, significantly enhancing the user experience. In some situations, self-service terminals can also collect already issued cards for reuse. However, in practical applications, during the card collection process, issues can arise where a new card is inserted before the previous one has been completely collected, potentially causing card malfunctions during the collection process.

[0048] To achieve the above objectives, the present invention proposes an anti-multiple card insertion mechanism 300.

[0049] Reference Figures 1 to 6 The anti-multiple card insertion mechanism 300 proposed in this utility model is applied to a self-service terminal device 100. The self-service terminal device 100 includes a housing 10 and a card dispensing slot 12 disposed on the housing 10. The anti-multiple card insertion mechanism 300 includes:

[0050] An outer cover 45 is fixed to the surface of the housing 10 and covers the card retrieval opening 12. The outer cover 45 and part of the housing 10 enclose an installation space. The outer cover 45 is also provided with a card retrieval slot 451, which communicates with the installation space and is positioned opposite to the card retrieval opening 12.

[0051] A door stop switch 30 is provided in the installation space. The door stop switch 30 can move relative to the housing 10 to open or close the card retrieval port 12.

[0052] A contact switch 40 is provided in the installation space, and part of the structure of the contact switch 40 is located on the side of the door stop switch 30 near the card slot 451;

[0053] When card 90 is inserted into the card slot 451, the contact switch 40 contacts card 90, and the blocking switch 30 opens the card slot 12 according to the contact signal of the contact switch 40; after card 90 enters the card slot 12, the blocking switch 30 closes the card slot 12.

[0054] The anti-multiple card insertion mechanism 300 proposed in this utility model is applied to a self-service terminal device 100. The self-service terminal device 100 includes a housing 10, within which an installation cavity 11 is formed. A transmission channel 14 is provided within the installation cavity 11, and a card dispensing slot 12 is also provided on the housing 10. The installation cavity 11 contains a card holder 50, a card dispensing mechanism 70, a cam mechanism 80, a card distance adjustment mechanism 83, a transmission mechanism 60, etc.

[0055] During card dispensing, the card-dispensing mechanism 70 dispenses the card 90 from the card outlet at the bottom of the card compartment 50, allowing the card 90 to enter the transmission channel 14 through the outlet. Under the action of the transmission mechanism 60, the card 90 is then transported to the card retrieval slot 12. Part of the card 90 protrudes from the card retrieval slot 451 at the card retrieval slot 12 for easy card retrieval by the user. The card compartment 50, cam mechanism 80, transmission mechanism 60, and card-dispensing mechanism 70 are all existing technologies; therefore, their structures and working principles will not be described in detail here.

[0056] When card 90 needs to be retrieved, the user inserts card 90 into card slot 451. The barrier switch 30 opens card retrieval port 12 via a contact signal from contact switch 40, allowing card 90 to pass through card retrieval port 12 and enter transmission channel 14, thus enabling the self-service terminal device 100 to perform card retrieval. The anti-multiple card insertion mechanism 300 proposed in this invention specifically functions during the card retrieval state of the self-service terminal device 100. When card retrieval is required, the user inserts card 90 into the self-service terminal device 100 from the external card slot 451. The contact switch 40 contacts card 90 to obtain a card retrieval signal. At this time, the barrier switch 30 opens card retrieval port 12 based on the card retrieval signal obtained from contact switch 40, allowing card 90 to enter the transmission channel 14 inside the self-service terminal device 100 via card retrieval port 12. At this time, since card 90 has been fully inserted into card retrieval slot 12, but the self-service terminal equipment 100 has not yet completed the retrieval of card 90, in order to prevent the user from inserting card 90 into card retrieval slot 451 again, which would cause congestion in the conveying channel near card 90, the barrier switch 30 quickly closes card retrieval slot 12 according to the signal from the contact switch 40 after card 90 is separated from the contact switch 40. This prevents the user from inserting multiple cards 90 into the self-service terminal equipment 100 in a short period of time before the barrier card 90 is fully retrieved, thus ensuring the normal operation of the self-service terminal equipment 100.

[0057] Reference Figures 1 to 6 In one embodiment of this utility model, the door stop switch 30 includes:

[0058] Electromagnet 31, guide and limit part 311 The side of the electromagnet 31 is also provided with a guide and limit part 311;

[0059] A door stop plate 32 is rotatably disposed within the installation space (not shown in the figure). The door stop plate 32 has a limiting section 321 and a door stop section 323. The limiting section 321 is disposed near the guide limiting part 311, and the door stop section 323 is disposed near the card retrieval port 12.

[0060] The electromagnet 31 attracts or releases the gate plate 32 according to the signal of the contact switch 40. The guide and limit part 311 guides and limits the movement of the gate plate 32 so that the gate section 323 moves to the bottom of the card retrieval port 12 to open the card retrieval port 12.

[0061] In one embodiment of this utility model, the electromagnet 31 controls the barrier plate 32 by energizing or de-energizing it. The barrier plate 32 has a clearance groove at its end corresponding to the guide limiting part 311, which also forms a U-shaped groove. The end of the barrier plate 32 is inserted into the U-shaped groove, and a limiting shaft 3111 is also provided on the guide limiting part 311, which passes through the clearance groove. When the electromagnet 31 is energized, it attracts the barrier plate 32 to drive it to rotate. The guide limiting part 311 guides and limits the movement direction of the barrier plate 32, causing it to move to below the card retrieval slot 12, thereby opening the card retrieval slot 12 and allowing the card 90 to pass through the card retrieval slot 12 into the transmission channel 14 inside the self-service terminal device 100.

[0062] Reference Figures 1 to 6 In one embodiment of the present invention, the gate switch 30 includes a second reset member 33, which is connected to the gate plate 32 and the housing 10 respectively. When the electromagnet releases the limiting segment 321, the second reset member 33 drives the gate plate 32 to reset.

[0063] In one embodiment of this utility model, the second reset member 33 is a torsion spring, which is used to drive the door stop plate 32 to reset in the opposite direction of the opening direction. The torsion spring abuts against both the door stop plate 32 and the housing, thereby driving the door stop plate 32 to move away from the electromagnet 31 after the magnetism of the electromagnet 31 disappears, thus maintaining the closed latch 12 state.

[0064] Reference Figures 3 to 6 In one embodiment of this utility model, the gate plate 32 further includes a fixed section 322, the limiting section 321 and the gate section 323 are respectively connected to the two ends of the fixed section 322, and together with the fixed section 322, form a first receiving groove; the gate switch 30 further includes a first rotating shaft 35, the limiting section 321 and the gate section 323 are respectively disposed in a first shaft hole, the first rotating shaft 35 passes through the first shaft hole and is fixed to the housing 10, the second reset member 33 is sleeved on the surface of the first rotating shaft 35 and accommodated in the first receiving groove, and the two ends of the second reset member 33 elastically abut against the limiting section 321 and the gate section 323 respectively.

[0065] In one embodiment of this utility model, the fixing section 322, the limiting section 321, and the blocking section 323 of the blocking plate 32 are an integral structure. The fixing section 322, the limiting section 321, and the blocking section 323 respectively form a right-angle structure, so that the blocking plate 32 roughly encloses and forms a U-shaped first receiving groove, which provides space for the installation of the second reset member 33. The first rotating shaft 35 passes through the limiting section 321 and the blocking section 323 respectively and is fixed to the housing 10, thereby realizing the relative rotational connection of the blocking door.

[0066] Using an electromagnet 31 and a second reset element 33 to control the opening or closing of the baffle plate 32 can achieve rapid response, reduce errors, and improve reliability.

[0067] Reference Figures 3 to 6 In one embodiment of this utility model, the contact switch 40 includes:

[0068] The signal sensing device 41 includes a sensing structure 413 disposed in the installation space. A sensing groove 4131 is formed on the surface of the sensing structure 413. A signal transmitter and a signal receiver are provided on the side of the sensing groove 4131.

[0069] The contact structure 43 is rotatably disposed within the installation space. The contact structure 43 includes a contact member 433 and a signal blocking member 435. The signal blocking member 435 is connected to the contact member 433, and one end of the signal blocking member 435 extends into the sensing groove 4131. A portion of the structure of the contact member 433 is located on the side of the door stop switch 30 near the card retrieval slot 451.

[0070] The card 90 is inserted into the card slot 451 and abuts against the contact part 4334 to drive the contact member 433 to rotate relative to the housing 10, thereby causing the signal blocking member 435 to move to separate from the sensing slot 4131, so that the signal sensing device 41 can receive the card insertion signal.

[0071] In one embodiment of this utility model, the signal sensing structure 413 can be a photoelectric sensor, i.e., a device that converts light signals into electrical signals using the photoelectric effect. The photoelectric sensor can be a through-beam photoelectric sensor, consisting of a transmitter and a receiver. The transmitter emits a light beam, and the receiver receives the light beam. When an object blocks the light beam, the sensor outputs a signal. Alternatively, the photoelectric sensor can also be a reflective photoelectric sensor, where the transmitter and receiver are integrated into the same device. The emitted light beam is reflected by a reflector (such as a reflector or the surface of an object) and then received by the receiver. The sensing structure 413 is connected to the housing 10 via a mounting base 411, wherein the sensing structure 413 is fixed to the surface of the mounting base 411.

[0072] The contact structure 43 is located on one side of the sensing structure 413. The contact structure 43 includes a contact member 433 and a fixing member 431. The contact member 433 is rotatably connected to the housing 10 through the fixing member 431. The contact member 433 includes a first connecting part 4331, a second connecting part 4332, a third connecting part 4333, and a contact part 4334, which are bent in sequence. The first connecting part 4331, the second connecting part 4332, and the third connecting part 4333 form a second receiving groove. The first connecting part 4331 and the third connecting part 4333 are respectively provided with a third shaft hole. The third rotating shaft 437 passes through the third shaft hole (not shown in the figure) and is connected to the fixing member 431. The contact part 4334 is located on the side of the door stop switch 30 near the card retrieval slot 451. The contact portion 4334 is arc-shaped, and its side is bent to form a guide surface. This allows the card 90 to make smooth and seamless contact with the contact portion 4334, preventing jamming during contact between the contact member 433 and the card 90. The contact switch 40 also includes a third reset member 436, which is a torsion spring. The third reset member 436 is sleeved on the surface of the third rotating shaft 437 and elastically abuts against the first connecting portion 4331 and the third connecting portion 4333. The end of the signal blocking member 435 away from the sensing groove 4131 is sleeved on the surface of the third rotating shaft 437. During the insertion of card 90, card 90 applies external force to contact member 433, causing contact member 433 to rotate relative to the housing, while simultaneously squeezing third reset member 436. When card 90 separates from contact member 4334, the external force disappears, and third reset member 436 drives contact member 433 to move signal blocking member 435 back into sensing slot 4131.

[0073] This utility model also proposes a self-service terminal device 100, which includes an anti-multiple card insertion mechanism 300. The specific structure of the self-service terminal device 100 is as described in the above embodiments. Since the self-service terminal device 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0074] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
