DETAILED DESCRIPTION OF PREFERRED EMBODIMENT
In the following description, reference is made to the accompanying drawings which form a part hereof, and which is shown, by way of illustration, an embodiment of the present invention. It is understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention.
The preferred embodiment of the present invention discloses apparatus for an operator of a coin changer having a removable cassette to easily load or to modify the coin store types when there is insufficient lighting. A light source illuminates the coin stores when the cassette is moved out of its dispensing position for hand loading or for making changes to the coin stores. Other sound and light effects are available to the operator to make sure that the set up was complete.
Throughout this application the term “user” is defined to be an owner of a device that includes a coin changer, such as a vending machine. “User” also encompasses the owner's agents or employees or anyone else acting to service or otherwise resupply the device that includes the coin changer. The term “user” is to be interpreted broadly, but it specifically excludes anyone whose primary or sole purpose is to insert money into the machine as payment for products or services.
Referring to FIG. 1, there is shown a perspective view of the coin changer housing 100 with its coin acceptor 102, a coin intake funnel 104, a light source 105 and its payout base 108. An aperture 107 is used to send an infrared beam out to the cassette (106 in FIG. 2) and, when the cassette is in position, provides a return path through an aperture 109 to a photo sensor. In normal operation, the cassette 106 is inserted into the area above the payout base 108, in an operating position.
In FIG. 2, the coin changer housing 100 is attached to the coin cassette 106. In FIG. 2, the coin cassette 106 is shown rotated away from the housing 100 on two hinges 109. The coin cassette 106 comprises six coin stores 110, 112, 114, 116, 118, and 120. The light source 105 illuminates the coin stores, which in the most preferred embodiment are clear tubes, when the cassette 106 is moved out of its operating position.
Referring to FIG. 3, the coin cassette 106 comprises two supporting halves 132 and 134. In FIG. 3 the two supporting halves 132 and 134 are shown separated thereby revealing a light directing device 142. The light directing device 142 is preferably a prism. When the cassette 106 is in the operating position, the light directing device 142 directs a light beam from the aperture 107 through the light directing device 142 and back to the aperture 109 behind which a photo sensor is located. When the cassette 106 is not in the operating position, the light directing device 142 will not be in alignment with either or both of the apertures 107 and/or 109 and the light from the aperture 107 will not be directed back to the aperture 109 and the photo sensor. The light source 105 is turned on by a controller operating the coin changer when the optic path is interrupted. As a result, a light source 105 is automatically illuminated whenever a technician has removed the coin cassette 106. The light source 105 also provides an indication to a technician whether the two halves 132 and 134 have been properly aligned and configured with respect to one another and whether the cassette 106 has been properly and aligned and configured with respect to the changer housing 100.
The two supporting halves 132 and 134 of the cassette 106 are releasably fastened together by the magnets 138 and ferrous pieces 140 respectively connected thereto.
FIG. 4 shows the acceptor portion 102 of the coin changer comprising a keypad-display module 200. When a sorting gate portion 400 is rotated, an audible signal generator 300 is visible. The audible signal generator 300 can be any known sound generating device, such as an electromagnetic speaker having a voice coil or a piezoelectric device. In the most preferred embodiment, the audible signal generator 300 can be used to provide an audible indication that the cassette 106 has been properly placed back in its operating position. It can also be used to provide a different audible indication upon the existence of an error and can also provide an audible indication of the type of error, such as through different tones or through different series of tones.
FIG. 5 is a view of the keypad display module 200 showing the keypad controls 502 and the display 504. A user will activate the keys and use the display as a feedback to communicate instructions to the coin changer that configure its operation. For example, as shown in the flow chart of FIG. 6, using the keypad controls 502, the user can toggle the operation of the audible signal generator 300 to enable or disable audible sounds. Audible signals are generally considered useful, however, sometimes due to surrounding conditions a user may chose to disable audible sound.
Audible and visual indications through the light source 105 and the audible signal generator 300 can also be implemented with autotest features of a coin changer. FIG. 7 shows the changer activity when the user selects the changer auto-test mode of operation. The user could select this mode of self diagnostic in which the changer will automatically move from test to test in steps with results of every step shown on the display 504. Other test modes could also be selected, e.g. one test at a time, when the changer will perform a self check of one feature only and wait for another command from the user.
FIG. 8 shows the “warning” and “out of service” messages that are displayed on the display portion of the keypad-display module 200. Other messages could also be introduce at a later time as user defined messages.
The coin changer of the preferred embodiment incorporates a range of features to assist the user. The coin storage cassette is illuminated when not in its operating position. When the cassette is attempted to be returned to the operating position, but is not sited properly, the illumination remains on and an audible sound is turned on to alert the user. The display shows the message “error” until the condition is removed. When the un-sited condition is removed, the sound and the illumination will be turned off, and the display will clear the message “error”.
Other conditions may activate the audible and visual feedback to alert the user that the changer is in a non-ready state.
Using the keypad controls 502 of the keypad-display module 200 of FIG. 5 and the sequence of entries as shown in the table of FIG. 7 the user could set up an auto-test mode of the changer. The changer enters a self diagnostic mode with multiple steps. The display portion of the keypad-display module reports the status of each of the steps. FIG. 8 shows the different types of messages possible. There are two types of messages: warnings, when the error is not essential and the changer remains functional and “out of service” if the error is critical and the changer is not operational. All warnings and out of service messages are accompanied by an audible beep and illumination from the cassette light source. In FIG. 6 a sequence of keys allows the user to enable or disable sound or illumination feedback.
The forgoing description of the preferred embodiment of the invention has been presented for the purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Many modifications and variations are possible in light of the above teaching. It is intended that the scope of the invention be limited not by the details of the embodiments presented in this description. The above specification, examples, and data provide a complete description of the manufacture and use of the invention. Many embodiments of the invention can be made without departing from the spirit and scope of the invention.
