1. Field of the Invention
The present invention relates to a coin slope for guiding an ejected coin to a coin receiver.
2. Description of the Related Art
A coin slope includes a sloping surface which makes an ejected coin slide down Lo a coin receiver by its own weight. A conventional coin slope is used as a part of various machines. In Japanese Laid-Open Publication No. 2000-132729 and Japanese Laid-Open Publication No. 2000-339525, a coin slope provided to a vending machine is described. A sloping surface of this coin slope receives a coin ejected from one side of this sloping surface and guides this coin to a coin receiver.
When ribs are provided to a sloping surface of a coin slope in order to reduce a contact resistance against a coin, a problem described below occurs.
However, the coin C which freely falls from directly above the coin slope 1 drops in a gap between the longwise ribs 3 without lying on the longwise rib 3 and rolls down, as shown in
For solving the problem described above, a bumping wall 5 may be provided right in front of coin receiver 4. The rolling coin C bumps against the bumping wall 5.
Accordingly, it is an object of the present invention to prevent a coin which drops in a gap between longwise ribs and rolls down to a coin receiver from jumping out of the coin receiver without providing a bumping wall against which the rolling coin bumps right in front of the coin receiver.
According to one aspect of the present invention, a coin slope includes a sloping surface which slopes downward; longwise ribs which are provided to be adjacent to each other on the sloping surface, and which extend from an upper area of the sloping surface to a lower area of the sloping surface; and a diagonal rib which diagonally crosses a direction orthogonal to a direction of a gravitational force on the sloping surface and which is not taller than the longwise ribs.
According to another aspect of the present invention, a coin slope includes a sloping surface which slopes downward; longwise ribs which are provided to be adjacent to each other on the sloping surface, and which extend from an upper area of the sloping surface to a lower area of the sloping surface; and an interference member which is not taller than the longwise ribs and which includes a slope connected to two adjacent longwise ribs.
According to another aspect of the present invention, a method includes installing a coin ejecting machine which includes a coin outlet through which a coin is ejected; and installing a coin slope in a position to which a coin ejected through the coin outlet falls down. The coin slope includes: a sloping surface which slopes downward; longwise ribs which are provided to be adjacent to each other on the sloping surface, and which extend from an upper area of the sloping surface to a lower area of the sloping surface; and a diagonal rib which diagonally crosses a direction orthogonal to a direction of a gravitational force on the sloping surface and which is not taller than the longwise ribs.
According to a further aspect of the present invention, a method includes installing a coin ejecting machine which includes a coin outlet through which a coin is ejected; and installing a coin slope in a position to which a coin ejected through the coin outlet falls down. The coin slope includes: a sloping surface which slopes downward; longwise ribs which are provided to be adjacent to each other on the sloping surface, and which extend from an upper area of the sloping surface to a lower area of the sloping surface; and an interference member which is not taller than the longwise ribs arid which includes a slope connected to two adjacent longwise ribs.
A more complete appreciation of the present invention and many of the attendant advantages thereof will be readily obtained as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings, wherein:
The first embodiment of the present invention is explained based on
The self-checkout system 11 includes an attendant terminal 501 which is a kind of a personal computer and the self-checkout terminals 101 which are assigned to the attendant terminal 501. The self-checkout terminal 101 is includes a settlement terminal 201 and a weighing apparatus 301. The settlement terminal 201 performs a merchandise sales data processing based on merchandise codes inputted through a barcode scanner 203 (see
An outside part of the settlement terminal 201 is a housing 202 which houses various units of the settlement terminal 201. The housing 202 includes a base housing 202a which is laid out on a floor, a small upper housing 202b which is laid out on a back side area of a top surface of the base housing 202a, a right housing 202c which is laid out on a right side of the upper housing 202b, and a door panel 202d which is laid out on a front face of the right housing 202c. A basket placement table 102 for placing a basket BK in which items to be purchased by a customer are put is laid out on a left side of the base housing 202a. The basket placement table 102 has a frame 103 on its top surface. The frame 103 positions the basket BK.
Various user interfaces are laid out on the housing 202 (above all, the upper housing 202b) to make it possible for a customer who faces a front face of the self-checkout terminal 101 to operate the self-checkout terminal 101.
The barcode scanner 203 is provided to the upper housing 202b. The barcode scanner 203 scans merchandise codes of various items. An LCD 210 is provided to the upper housing 202b. The LCD 210 has the touch panel 211 on its display surface.
An indicating pole 217 which indicates a present condition of the self-checkout terminal 101 stands on a top surface of the upper housing 202b. The standing area of the indicating pole 217 is a back side area of the LCD 210. A light emitting unit 218 which emits blue light and red light selectively is provided to a top of the indicating pole 217.
The right housing 202c houses a coin unit 221 (see
A receipt outlet 208 is provided to an area above the bill inlet 215 and of the front face of the door panel 202d. The receipt printer 251 (see
The weighing apparatus 301 is provided to an area which is at a left side of the base housing 202a and a front side of the right housing 202c. The weighing apparatus 301 includes a weighing plate 303 which is on a top of the weighing apparatus housing 302 and a pair of bag holding frames 304 which are on the top of the weighing plate 303. The bag holding frames 304 face each other. A top surface of the weighing plate 303 is a placement table 303a. The bag holding frames 304 stand on the placement table 303a. The upper part of each of the bag holding frames 304 is bent inside for the upper part to be a bag holder 314 on which a handle of a bag like a plastic bag is hung.
The weighing apparatus 301 inside includes a loadcell unit (not shown) which weighs items placed on the weighing plate 303 and sends an output signal. The output signal sent by the loadcell unit is amplified by an amplifier (not shown). The amplified output signal is converted into a digital signal by an analog-digital converter (not shown). An operation part (not shown) makes a weight analysis based on the digital signal and sends weight data as a result of the weight analysis to the settlement terminal 201 through a sending part (not shown).
Next, various units the right housing 202c houses are explained.
The coin unit 221, the bill recycling machine (not shown), and the receipt printer 251 are unitized into the inner unit 204. The inner unit 204 is stored in the right housing 202c. A slide rail mechanism 230 makes it possible to pull the inner unit 204 from the right housing 202c and to push the inner unit 204 into the right housing 202c. The bill recycling machine is provided to a left side of the coin unit 221 adjacently when seen from the front side of the self-checkout terminal 101, though the bill recycling machine is hidden by the coin unit 221 in
A positional relationship between the coin inlet 213 which is provided to the door panel 202d and an entry part 213a of the coin unit 221 is explained. When the coin unit 221 is pushed into the right housing 202c and the door panel 202d is shut, a coin which is inserted into the coin inlet 213 falls down to the entry part 213a and enters the coin unit 221 through the entry part 213a.
A positional relationship between the coin receiver 416 which is provided to the door panel 202d and a coin passing gate 415 of the coin slope 401 described below is explained. When the coin unit 221 is pushed into the right housing 202c and the door panel 202d is shut, a coin which passes the coin passing gate 415 falls down to the coin receiver 416.
The coin unit 221 includes a coin recycling machine 222 and an extra tube 223 which are unitized. Coins of type “X” can be put in the coin recycling machine 222, and the coin recycling machine 222 ejects the coins. The extra tube 223 ejects coins of type “Y”. The coin recycling machine 222 is provided to a front side of the extra tube 223 adjacently.
The entry part 213a which opens upward is provided to a front side of an upper side of the coin recycling machine 222 in order to induct a coin C into the coin recycling machine 222. A coin outlet 222a (see
The four extra tubes 223 are provided for respective coin types with their axial direction being vertical. The top part of each of the extra tubes 223 is opened to be an intake part 223b which permits an intake of the coin C into the extra tube 223. The coin C which is taken through the intake part 223b is ejected through an extra tube coin outlet 223c which is provided to an under part of the extra tube 223 by an ejection mechanism (not shown) which ejects the coin C according to a control from a controller (riot shown) of the settlement terminal 201. On condition that the coin C of type “Y” not stored in the coin recycling machine 222 is stored in the extra tube 223 preliminarily, the extra tube 223 ejects the coin C according to a control from the controller of the settlement terminal 201.
The coin slope 401 is provided to a position to which the coin C ejected through the coin outlet 222a or the extra tube coin outlet 223c falls down and which is at an underside of the coin unit 221. The coin slope 401 makes the ejected coin C slide down by its own weight to the coin receiver 416 with the door panel 202d shut.
The coin slope 401 is not provided to an underside of the sub coin outlet 222b of the coin recycling machine 222. The coin C ejected through the sub coin outlet 222b falls down to an area underside of the coin slope 401 without being disturbed. On the area, a coin storing case 231 which can store coins is laid out. So, the coin of type “Y” ejected through the sub coin outlet 222b will be stored in the coin storing case 231.
Next, the coin slope 401 is further explained based on
Side surface parts 412 are provided to both sides of the sloping surface 411. The side surface part 412 prevents the coin C from dropping out of the coin slope 401. The sloping surface 411 and the side surface part 412 are connected by a curved surface part 413. The corner of the curved surface part 413 is rounded off. A front face panel 414 like a double-deck panel member is provided to a front side (left lower side in
As shown in
The sloping surface 411 is further explained. As shown in
The diagonal rib 431 forms an arrow pointing to the coin receiver 416. That is, as shown in
The diagonal rib 431 is further explained. Two ribs inclined from a side part of the sloping surface 411 to a center part of the sloping surface 411 are connected to each other at the center part so as to form an arrow. In this, the diagonal rib 431 gets across the longwise rib 421. The diagonal rib top surfaces 431a have the same height as the longwise rib top surfaces 421a. The diagonal ribs 431 are provided along a longer direction of the sloping surface 411 at regular intervals (see
The diagonal rib side surface 431b connected to the diagonal rib top surface 431a has an arc-like base which runs along the sloping surface 411 and the longwise rib side surface 421b.
Next, a case that the coin C ejected through such as the extra tube 223 is made to slide down to the coin receiver 416 by the coin slope 401 is explained. For example, when the coin C is ejected through the extra tube coin outlet 223c, the ejected coin C slides down by its own weight with its one surface on the virtual plane which is made by the longwise rib top surface 421a (see
Sometimes, the ejected coin C drops in a gap between the two longwise ribs 421 and stands on the sloping surface 411 between the two longwise ribs 421 without lying on the longwise rib top surface 421a.
The coin C which drops in the gap between the two longwise ribs 421 rolls down by its own weight on the sloping surface 411 along the longwise rib 421. The coin C which is ejected through the extra tube coin outlet 223c falls down to an upper side of the sloping surface 411. Therefore, if the diagonal rib 431 had been not provided, the coin C would rush to the coin receiver 416 and would jumps out of the coin receiver 416.
However, in the first embodiment, the diagonal rib 431 is provided to a position where the diagonal rib 431 interferes with a trajectory of the coin C which rolls down between the two longwise ribs 421. Therefore, the coin C which rolls down between the two longwise ribs 421 bumps against the diagonal rib 431. Because the diagonal rib 431 diagonally crosses a direction of the coin C -movement, an edge of a one side of the coin C bumps the diagonal rib 431, first. So, a lower edge of the coin C is pushed by the diagonal rib 431 from outside. And, an upper edge of the coin C falls down outward (a direction of an arrow in
As described above, according to the first embodiment, the ejected coin C slides down by its own weight lying on the longwise rib top surface 421a without rolling down on the sloping surface 411. So, the coin C is prevented from rushing to the coin receiver 416 and jumping out of the coin receiver 416.
The diagonal rib 431 should be a member which diagonally crosses the longwise rib 421 from one side of the sloping surface 411 to the other side, and it is riot limited to a member which forms an arrow.
In the case that the present example of the diagonal rib 431 is provided, the ejected coin C slides down by its own weight lying on the longwise rib top surfaces 421a without rolling down on the sloping surface 411. So, the coin C is prevented from rushing to the coin receiver 416 and jumping out of the coin receiver 416.
Next, a second embodiment of the present invention is explained based on
In the second embodiment, as a plurality of the interference members 531 are provided linearly, it is like a rib orthogonal to a longer direction of the longwise rib 421. Then, as shown in
As described above, according to the second embodiment, the ejected coin C slides down by its own weight lying on the longwise rib top surface 421a without rolling down on the sloping surface 411. So, the coin C is prevented from rushing to the coin receiver 416 arid jumping out of the coin receiver 416.
In the first embodiment and the second embodiment, the example of the application to the coin slope 401 which is provided to the self-checkout terminal 101 is shown. But, the present invention may be applicable to a coin slope provided to another coin ejecting machine (for example, a beverage vending machine, a parking ticket vending machine, etc).
Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
