ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a twin-shaft swinging type coin-identifying/receiving device.
2. Description of the Prior Art
FIG. 6
shows a conventional coin receiving device of a public phone, vending machine, etc. In such coin receiving device, two gate boards
33
,
34
are respectively pivotally mounted at incoming ends of two coin exits
31
,
32
for closing the coin exits
31
,
32
at normal time. A pivot shaft
35
is disposed on outer side of the coin receiving device and two swinging members
36
,
37
are pivotally connected with the pivot shaft
35
. The two swinging members
36
,
37
are operated respectively by the stems
381
,
391
of two cylinder-type electromagnetic valves
38
,
39
to swing up and down. The gate boards
33
,
34
are coupled with and driven by the swinging members
38
,
39
to deflect and selectively open one of the coin exits
31
,
32
, permitting an inserted coin to drop out therefrom.
According to the above arrangement, the two swinging members
38
,
39
are pivotally connected with the same pivot shaft
35
and leant against each other. Under such circumstance, no matter which swinging member
36
or
37
is drivingly swung by the electromagnetic valve
38
or
39
, the pivot shaft
35
will be worn and the other swinging member
36
or
37
will be also worn. Therefore, after a period of use, the pivot shaft
35
and the two swinging members
36
,
37
will be quickly worn out. This will lead to shaking of the swinging members in operation. Also, the excessively large gap will result in inaccurate operation and thus the two gate boards
33
,
34
can be hardly driven. Therefore, the using life of the device will be shortened.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide a twin-shaft swinging type coin-identifying/receiving device including: an identifying device including a base board section and a guide board section resiliently pivotally mounted on one side of the base board section, the base board section and the guide board section defining therebetween a coin slide way, an identifying member being mounted on at least one side of the identifying device for identifying whether a coin sliding through the coin slide way is a true one or a fake one; and a receiving device installed at a bottom end of the identifying device. The receiving device is formed with an internal guide way for accepting the coin dropping from the identifying device. A bottom end of the guide way is communicated with both a first and a second coin releasing ways. Two projecting pivot shafts are radially disposed on outer side of the receiving device. Two swinging members are respectively pivotally mounted on the pivot shafts. The swinging members are respectively operated and swung by two swinging type electromagnetic valves so as to drivingly rotate two gate boards pivotally mounted at incoming ends of the first and second coin releasing ways and thus open or close the first and second coin releasing ways, whereby the coin can be guided to drop out from the first or second coin releasing way.
The present invention can be best understood through the following description and accompanying drawings wherein:
