COIN HANDLING APPARATUS

Abstract: A coin handling apparatus (20, 50) having a coin discriminating means (21, 51) and a plurality of coin retaining means (22, 23, 24, 25, 52, 53, 54, 55) wherein at least one (25a, 29a, 55a, 59a) of coin outlets is disposed on the side surface (39, 69) of the coin discriminating means. Since the number of coin outlets being disposed on the bottom surface of the coin discriminating means (21, 51) is decreased, the width of the coin discriminating means can be decreased and the size of the means can be made small. The space defined by the decrease of the size can be utilized as a space for extending an auxiliary coin retaining means (26, 56), thereby increasing the capacity for change to be retained.

Description: The present invention relates to a coin handling apparatus which may be built into a vending machine etc., and which discriminates between deposited coins and retains an accepted coin. The conventional coin handling apparatus is constructed of, for instance, a coin discriminating device 1, a plurality of coin retaining tubes 2, 3, 4 and 5 and auxiliary coin retaining tubes 6 and 7 as shown in FIGS. 6, 7A and 7B (for example, Japanese Utility Model Publication SHO 60-44162). Coin discriminating device 1 has a coin inlet 8 at the upper portion thereof and a plurality of coin outlets 2a, 3a, 4a and 5a and a coin outlet 9 for an unacceptable coin (for example, a metal slug) on the bottom surface thereof. In the coin discriminating device 1, coin validation coils 10 detecting the authenticity of a deposited coin and the type of the coin, a coin chute 11 constituting a coin path for the deposited coin and distributing gates 13, 14 and 15 for distributing the destination of the coin according to the type of the coin detected by the coin validation coils are provided. Coin retaining tubes 2, 3, 4 and 5 retain, for example, 10 yen coins 16, 50 yen coins 17, 100 yen coins 18 and 500 yen coins 19, respectively, and auxiliary coin retaining tubes 6 and 7 can retain a large number of coins for giving change. As shown in FIG. 7A, a coin deposited into coin inlet 8 is tested by coin validation coils 10 in accordance with the authenticity and type thereof during passage through coin chute 11, and an unacceptable coin (a rejected coin) is returned through coin outlet 9 to a return opening (not shown). An acceptable coin is distributed to a corresponding coin path by distributing gates 13, 14 and 15 and then it passes through one of coin outlets 2a, 3a, 4a and 5a and falls into one of coin retaining tubes 2, 3, 4 and 5. In such a conventional apparatus, however, since all of coin outlets 2a, 3a, 4a and 5a and rejected coin outlet 9 are arranged on the bottom surface of coin discriminating device 1, the width W₁ of the coin discriminating device cannot be decreased to a great extent. Although it might seem possibe to arrange the coin outlets in two lines on the bottom surface in order to decrease the width W₁, in this case it is technically difficult to dispose coin paths from distributing gates 13, 14 and 15 to coin outlets 2a, 3a, 4a and 5a without interference with each other in discriminating device 1 and also to dispose coin paths from the coin outlets to coin retaining tubes 2, 3, 4 and 5 without interference with each other. Amongst such coin handling apparatuses, there is one which has an overflow switching mechanism switching a coin path communicating with a coin retaining tube to an overflow coin path communicating with a cash box when the coin retaining tube is filled with coins. For example, JP-A-61-237190 and JP-A-52-43497 disclose such a type of coin handling apparatus, and any one of the apparatuses disclosed in these publications has a coin discriminating device at the upper portion thereof and coin retaining tubes at the lower portion thereof. The apparatus disclosed in the former publication has four gates as coin distributing means, and a deposited coin is distributed to a rejected coin path, one of the acceptable coin paths or an overflow coin path communicating with a cash box by operation of the four gates according to the combination of opening or closing of the respective gates. The apparatus disclosed in the latter publication has three gates distributing unacceptable coins and acceptable coins and overflow sensors attached to respective coin retaining tubes, and when one of the coin retaining tubes is filled with coins, the overflow sensor detects it and the coin path to the coin retaining tube is switched to a coin path communicating with a cash box by the operation of the gates. In the apparatus disclosed in JP-A-61-237190, however, since four gates and four solenoids driving the gates are required and distributing means for distributing the overflow coins to the overflow coin path communicating with a cash box is disposed in the coin discriminating device, there is a certain limit to the extent to which the width of the coin discriminating device can be decreased. In the apparatus disclosed in JP-A-52-43497, since the gate distributing the overflow coin to the overflow path communicating with a cash box is provided in the coin discriminating device and the coin path downstream of the above distributing gate is also formed in the coin discriminating device, also there is an unsatisfactory limit to the extent to which the width of the coin discriminating device can be decreased. It would be desirable to provide a coin handling apparatus which can be made smaller, particularly of which the width can be decreased, thereby permitting an increase in the capacity of the coin retaining means and increasing the number of coins which can be retained. A coin handling apparatus according to the present invention comprises a coin discriminating means which is provided at an upper portion of the coin handling apparatus, the coin discriminating means having a coin testing means for detecting the type of a deposited coin, a distributing means for distributing a deposited coin to a destination according to the type of the coin detected by the coin testing means and a plurality of coin outlets to one of which the coin distributed by the distributing means is guided, and a plurality of coin retaining means which is provided at a lower portion of the coin handling apparatus, each of the coin retaining means communicating with a corresponding coin outlet of the coin outlets, each of the coin retaining means retaining therein the coin accepted by the coin discriminating means in accordance with the type of the accepted coin; and wherein at least one of the plurality of coin outlets is disposed on a side surface of the coin discriminating means. In embodiments where the coin handling apparatus further comprises a switching means for switching a coin path communicating with one of the coin retaining means to an overflow path communicating with a cash box when the number of coins retained in the coin retaining means reaches a given number, the overflow path extending from the distributing means is desirably the same as the path for the largest coins, and leads to another distributing means for distributing the largest coins to a coin path communicating with the coin retaining means for the largest coins, and overflow coins to a coin path communicating with the cash box. This futher distributing means is provided on the common path at a position outside of the coin discriminating means. In the coin handling apparatus, since a specific type of coins among the coins discriminated by the coin discriminating means are led to a coin retaining means through the coin outlet disposed on the side surface of the coin discriminating means, the number of the coin outlets on the bottom surface of the coin discriminating means can be decreased by the number of the coin outlets disposed on the side surface as compared with that in the conventional apparatus. As a result, the coin discriminating means can be made smaller in width. A certain space can be saved by making the coin discriminating means smaller, and for instance, if an auxiliary coin retaining means is extended into this space, the capacity of the retaining means for changes can be increased. In the coin handling apparatus wherein overflow coins are sent to a cash box, we can remove the need to provide a special overflow path in the coin discriminating means by making the overflow path in common with the coin path for the largest coin. Therefore, the size of the coin discriminating means itself can be decreased. Moreover, the size can be further decreased by disposing a distributing means for distributing the largest coin and the overflow coin on the common path at a position outside of the coin discriminating means. As a result, also in this type of coin handling apparatus, a certain space can be saved in the apparatus and an auxiliary coin retaining means can extend into the space. Some preferred exemplary embodiments of the invention will now be described with reference to the accompanying drawings which are given by way of example only, and thus are not intended to limit the present invention, and in which: FIG. 1 is an elevational view of a coin handling apparatus according to a first embodiment of the present invention; FIG. 2A is an elevational view of a coin discriminating means of the apparatus shown in FIG. 1, showing the inside mechanism of the coin discriminating means; FIG. 2B is a side view of the coin discriminating means shown in FIG. 2A; FIG. 2C is a bottom view of the coin discriminating means shown in FIG. 2A; FIG. 3 is a schematic perspective elevational view of a coin handling apparatus according to a second embodiment of the present invention; FIG. 4 is a sectional view of the apparatus of FIG. 3 taken along line IV-IV in FIG. 3; FIG. 5 is a sectional view of the apparatus of FIG. 4 taken along line V-V in FIG. 4; FIG. 6 is an elevational view of the conventional coin handling apparatus; FIG. 7A is an enlarged elevational view of the coin discriminating device of the apparatus shown in FIG. 6, showing the inside mechanism of the device; and FIG. 7B is a bottom view of the coin discriminating device shown in FIG. 7A. FIGS. 1, 2A, 2B and 2C illustrate a coin handling apparatus according to a first embodiment of the present invention. A coin handling apparatus 20 comprises a coin discriminating device 21 as a coin discriminating means disposed on the upper portion thereof and a plurality of coin retaining tubes 22, 23, 24 and 25 as coin retaining means and auxiliary coin retaining tubes 26 and 27 on the lower portion thereof. In the coin discriminating device 21, a coin inlet 28 having a hopper-like shape is provided on the top portion thereof and three coin outlets 22a, 23a and 24a are formed on the bottom surface thereof as shown in FIG. 2C. A coin outlet 25a for a 500 yen coin which is the largest coin and a coin outlet 29a for an unacceptable coin are formed in a line in the horizontal direction on a side surface 39 of the coin discriminating device 21 in this embodiment. A coin chute 31 as a coin path for a coin deposited into the coin inlet 28 is provided in the upper portion in the coin discriminating device 21. Two coin validation coils 30a and 30b are disposed above the chute 31, as coin testing means. The coin validation coils 30a and 30b magnetically detect the material and shape etc. of a coin passing through the chute 31 and detect the authenticity and the type of the coin. A plurality of distributing gates 33, 34 and 35 are arranged in the vertical direction on a portion of the exit side of the chute 31, as distributing means for distributing the destination of the deposited coin. Coin paths 22b, 23b, 24b, 25b, and 29b extend from distributing gates 33, 34 and 35 to coin outlets 22a, 23a, 24a and 25a and unacceptable coin outlet 29a, respectively. The distributing gates 33, 34 and 35 are opened and shut by solenoids 36, 37 and 38, respectively. The coin having passed through the coin validation coils 30a and 30b is led to one of coin outlets 22a, 23a, 24a, 25a and 29a through one of coin paths 22b, 23b, 24b, 25b and 29b via operation of distributing gates 33, 34 and 35. The combination of opening and shutting of the gates 33-35 is controlled according to the signal from the coin validation coils. Coin retaining tubes 22, 23, 24 and 25 have inside diameters substantially corresponding to the diameters of respective coins 42, 43, 44 and 45 to be accepted. Only coin retaining tube 25 for 500 yen coins is disposed behind coin retaining tubes 22, 23 and 24 and the upper portion of the tube 25 is curved and connected to coin outlet 25a on the side surface 39 of coin discriminating device 21. Unacceptable coin outlet 29a is connected to a discharging path 29 for unacceptable coins and the discharging path is connected to an appropriate return opening to a customer (not shown). Auxiliary coin retaining tubes 26 and 27 for retaining change therein are disposed on both sides of coin retaining tubes 22, 23 and 24. In contrast with the apparatus shown in FIG. 6, the left auxiliary coin retaining tube 26 has the same height as that of the right auxiliary coin retaining tube 27. Auxiliary coin retaining tubes 26 and 27 retain mainly 10 yen coins which are most frequently used as change. Change falls down to a change return mechanism 40 from the bottoms of the auxiliary coin retaining tubes in order. The change return mechanism 40 has the conventional structure. In the above coin handling apparatus, a coin deposited into coin inlet 28 passes through coin chute 31, and the authenticity of the coin is tested and the type of the coin is detected by coin validation coils 30a and 30b during passage. Then the coin is sent to one of five coin paths 22b, 23b, 24b, 25b and 29b by distributing gates 33, 34 and 35. An unacceptable coin, such as a metal slug or foreign coin, is returned through coin path 29b, coin outlet 29a and discharging path 29. A 10 yen coin 42 is led into coin retaining tube 22 through coin path 22b and coin outlet 22a. A 50 yen coin 43 is led into coin retaining tube 23 through coin path 23b and coin outlet 23a. A 100 yen coin 44 is led into coin retaining tube 24 through coin path 24b and coin outlet 24a. A 500 yen coin 45 is led into coin retaining tube 25 through coin path 25b and coin outlet 25a disposed on the side surface 39 of coin discriminating device 21. The operation of distributing gates 33, 34 and 35 is controlled, for example, as shown in Table 1. In Table 1, mark "o" shows the on state of a solenoid, and mark "x" shows the off state of a solenoid. A solenoid which has been turned on returns to its off state in a short period of time under the control of a timer.

Therefore, a space can be defined at a portion facing the side surface 39 of coin discriminating device 21. In this embodiment, auxiliary coin retaining tube 26 is extended up into this space and the capacity of the tube can be increased. Of course, the number of the coin outlets to be formed on the side surface 39 may be changed according to requirements. FIGS. 3-5 illustrate a coin handling apparatus according to a second embodiment of the present invention. Also in this embodiment coin handling apparatus 50 has a coin discriminating device 51 on the upper portion thereof and a plurality of coin retaining tubes 52, 53, 54 and 55, auxiliary coin retaining tubes 56 and 57 and a discharging chute 59 for unacceptable coins on the lower portion thereof. A coin inlet 58 having a hopper-like shape is provided on the top portion of the coin discriminating device 51. In the coin discriminating device 51, a coin chute 61 for deposited coins, coin validation coils 60a and 60b, three distributing gates 63, 64 and 65 and coin paths 52b, 53b, 54b, 55b and 59b extending from the distributing gates are provided. The coin validation coils 60a and 60b magnetically detect the material and shape etc. of the deposited coin passing through the chute 61 and detect the authenticity and the type of the coin. The distributing gates 63, 64 and 65 switch the coin paths 52b, 53b, 54b, 55b and 59b via the on-off operation of solenoids 66, 67 and 68 according to the type of the coin. In this embodiment, a coin outlet 55a of the coin path 55b for a largest coin and a coin outlet 59a of the coin path 59b for an unacceptable coin are disposed on the side surface 69 of the coin discriminating device 51. Coin retaining tubes 52, 53, 54 and 55 are disposed corresponding to the coin outlets of the coin paths 52b, 53b, 54b and 55b, respectively, and retain 10 yen coins, 50 yen coins, 100 yen coins and 500 yen coins, respectively. Auxiliary coin retaining tubes 56 and 57 are disposed on both sides of the coin retaining tubes 52, 53 and 54 and coins for change, mainly 10 yen coins 81 (FIG. 5), are manually put therein. Chute 59 for unacceptable coins (rejected coins) is connected to the coin outlet 59b and the lower portion of the chute is connected to a return opening (not shown). Although all the coin retaining tubes are shown in a line in FIG. 3 in order to make it easy to understand the routes of respective coins, actually unacceptable coin chute 59, auxiliary coin retaining tube 56 and coin retaining tube 55 for 500 yen coins are arranged in the thickness direction of the coin handling apparatus 50 and similarly auxiliary coin retaining tube 57 and a coin path 71 communicating with a cash box 77 are arranged in the same direction, as shown in FIGS. 4 and 5. The shape of the section of coin retaining tube 55 is almost the same as that of coin path 55b and the coin retaining tube can retain a 500 yen coin 82 therein with the coin substantially vertical. These arrangements and the structure of the tube can make the size of the apparatus fairly small. A change return mechanism 80 which is well known is provided below coin retaining tubes 52, 53, 54 and 55 and auxiliary coin retaining tubes 56 and 57 and the mechanism returns coins for change from the bottoms of the tubes in order. Overflow sensors 72, 73, 74 and 75 are attached on the upper portions of coin retaining tubes 52, 53, 54 and 55, respectively. Each overflow sensor detects the state that the corresponding coin retaining tube is filled with coins, and then, the coin path to the coin retaining tube is switched to coin path 71 communicating with cash box 77. Overflow path 76 for overflowed coins diverges from coin path 55b for the largest coin (500 yen coin) and is connected to coin path 71 communicating with cash box 77. On the divergent point, a distributing gate 78 for distributing the largest coin and the overflowed coin is provided, and a solenoid 79 for driving the gate is connected to the gate. Namely, coin path 55b from distributing gate 64 to distributing gate 78 constitutes a common coin path for the largest coins and for the overflowed coins. The distributing gate 78 is disposed on the common path at a position outside of coin discriminating device 51. A coin path 53c diverges from coin path 53b for 50 yen coins at a position above coin retaining tube 53. At the divergent point a distributing plate (not shown) having a hole or a slit for a coin to be distributed is provided. The coin path 53c is connected to coin path 71 and a 10 yen coin or 100 yen coin misled to coin path 53b can be sent to the coin path 71 through the coin path 53c. In the above coin handling apparatus 50, a coin deposited into coin inlet 58 is tested for the authenticity and type thereof by coin validation coils 60a and 60b during passage through coin chute 61. Then the coin is sent to one of the coin paths 52b, 53b, 54b, 55b and 59b by distributing gates 63, 64 and 65 according to the signal from the coin validation coils. Distributing gate 78 is controlled according to the signals from overflow sensors 72, 73, 74 and 75. Table 2 shows the modes of operation of the distributing gates 63, 64, 65 and 78. In Table 2, mark "o" shows the on state of a solenoid and mark "x" shows the off state of a solenoid. A solenoid which has been turned on returns to its off state in a short period under the control of a timer.

Acceptable coins are distributed as follows. When the deposited coin is a 500 yen coin, distributing gates 63 and 78 operate and the coin is led into coin retaining tube 55 through coin path 55b. When the deposited coin is a 100 yen coin, distributing gates 63 and 65 operate and the coin is led into coin retaining tube 54 through coin path 54b. When the deposited coin is a 50 yen coin, distributing gates 63 and 64 operate and the coin is led into coin retaining tube 53 through coin path 53b. When the deposited coin is a 10 yen coin, distributing gates 63, 64 and 65 operate and the coin is led into coin retaining tube 52 through coin path 52b. When coin retaining tube 52 is filled with 10 yen coins, overflow sensor 72 detects this state and coin path 52b is switched to coin path 55b as a coin path for overflow 10 yen coins. In this condition, only distributing gate 63 opens, and the next 10 yen coin is sent to cash box 77 through coin paths 55b, 76 and 71. With other coin retaining tubes 53, 54 and 55, the procedure is similar. In the coin handling apparatus 50, since the coin path for overflowed coins and the coin path 55b for the largest coins are constituted as a common path, the number of coin paths to be formed in the coin discriminating device 51 is not increased even if an overflow path is provided in the device. Therefore, the coin discriminating device 51 can be small even though the device has the distributing function for overflowed coins. Moreover, since the distributing gate 78 for distributing the overflow coins and the largest coins led along the common path 55b is disposed outside of coin discriminating device 51, the device further can be made smaller. As a result, a space 90 (FIG. 3) can be defined on a portion facing the side surface 69 of the device. The space 90 can be utilized to extend auxiliary coin retaining tube 56 upward as shown with a two-dot line in FIG. 3, and the capacity of the tube can be increased. In this case, distributing gate 78 and solenoid 79 therefor are disposed behind the extended tube.
