Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a banknote recognition apparatus for identifying the authenticity of a banknote, and more particularly to a banknote insertion opening / closing mechanism of the banknote identification apparatus.
[0002]
[Prior art]
In vending machines, banknote change machines and the like that can use banknotes, banknote identification devices are generally installed in order to identify the authenticity of inserted banknotes and to eliminate illegal ones. In such a bill recognition device, a bill is inserted from a bill insertion slot, and this bill is then identified by a bill recognition sensor while being conveyed along a predetermined conveyance path by a bill conveyance mechanism.
[0003]
Since the banknote insertion opening is open to the outside of the banknote recognition device, rainwater, dust, etc. may intrude into the banknote insertion opening as it is and may adversely affect the banknote transport mechanism, banknote identification sensor, etc. is there. As a technique for preventing this point, JP-A-8-63640 discloses the following mechanism for opening and closing the bill insertion slot.
[0004]
That is, this mechanism opens and closes the bill insertion slot by rotating up to 180 degrees while changing the center from the first shaft portion, the second shaft portion, and the first shaft portion to the second shaft portion. It is comprised from the insertion port door and the spring which always urges | biases an insertion port door to a close direction. The banknote insertion slot is opened by slightly rotating the insertion slot door in the opening direction with a finger from the closed state covered with the insertion slot door, thereby enabling the insertion of banknotes. By turning 180 degrees to the maximum open state, the banknote can be inserted most easily.
[0005]
The insertion port door also has a second shaft portion between 80 degrees and 180 degrees in the rotation from the closed state to the maximum open state with the first shaft portion between 0 degrees and about 80 degrees. It is designed to rotate in two stages while shifting the center of rotation.
[0006]
[Problems to be solved by the invention]
However, in the conventional insertion port opening / closing mechanism, there are two shaft portions that are the center of rotation of the insertion port door.
[0007]
Accordingly, an object of the present invention is to provide a banknote recognition apparatus having an insertion opening / closing mechanism that is simple in structure and advantageous in cost.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, in the present invention of claim 1, in the banknote identification device provided with a banknote insertion slot into which a banknote is inserted and an insertion slot opening / closing mechanism for opening and closing the banknote insertion slot, the insertion slot The opening / closing mechanism includes a single shaft portion, an insertion port door that opens and closes the bill insertion port by rotating about 180 degrees around the shaft portion, and a coiled spring that biases the insertion port door in the closing direction. The support part which supports the central-axis direction approximate center part of a shaft part via a spring is provided above the bill insertion slot.
[0009]
According to the present invention, the insertion slot door rotates about 180 degrees around a single shaft portion so that the bill insertion port can be opened and closed, so the number of parts is reduced compared to a conventional mechanism having two shaft portions. As a result, the cost can be reduced.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
1 to 4 relate to one embodiment of the present invention, FIG. 1 is an overall perspective view of a bill recognition device, FIG. 2 is an exploded perspective view of an insertion port opening / closing mechanism, and FIGS. 3 and 4 are insertion port doors. It is side explanatory drawing which shows roughly the closed state and maximum open state of this.
[0011]
The bill recognition device 1 includes a device main body 10 in which a bill conveyance mechanism, a bill recognition sensor (none of which is shown), and the like, and a front mask portion 20 attached to the front side of the device main body 10 are provided. A banknote insertion slot 21 (see FIGS. 2, 3, and 4) is opened on the surface (hereinafter referred to as “mask surface”) 20 a of the front mask portion 20, and an insertion for opening and closing the banknote insertion slot 21 is performed. The mouth opening / closing mechanism 30 is arranged as follows.
[0012]
That is, as shown in an exploded view in FIG. 2, the insertion port opening / closing mechanism 30 includes a shaft member 31, an insertion port door 32 that rotates around the shaft member 31 to open and close the bill insertion port 21, and an insertion port door. It is comprised from the spring 33 as an elastic member which always urges | biases 32 to a close direction. The mask surface 20 a is provided with a shaft support portion 34 that supports both ends of the shaft member 31 and a spring support portion 35 that supports the spring 33. The insertion slot door 32 has a shaft passing portion 32 a through which the shaft member 31 is passed, a spring receiving portion 32 b that receives both ends of the spring 33, and a knob that is pinched when a person inserting a bill opens the insertion slot door 32. A portion 32c is provided. The engagement between the shaft member 31 and the shaft support portion 34 is performed by press-fitting the groove 31a of the shaft member 31 into a flange 34a projecting on the inner side of the left shaft support portion 34, thereby improving the assemblability of the shaft member 31. It is improving.
[0013]
As shown in FIG. 3, the insertion slot door 32 is normally in a closed state covering the banknote insertion slot 21, thereby reliably preventing intrusion of rainwater, dust and the like from the banknote insertion slot 21. And when inserting a banknote (not shown) from the banknote insertion slot 21, the knob part 32c of the insertion slot door 32 in a closed state is pinched with a finger, and the insertion slot door 32 is resisted against the bias of the spring 33. It rotates in the opening direction to uncover the bill insertion slot 21 by the insertion slot door 32. The insertion port 32 can be rotated in the opening direction until it is limited by the mask surface 20a, as shown in FIG. The angle to the state is 180 degrees. Further, during the rotation of 180 degrees, the center of rotation of the insertion port door 32 is always the shaft member 31. When the finger is released from the insertion port door 32 in the maximum open state, the insertion port door 32 automatically returns to the closed state, which is the initial state, by the bias of the spring 32. At this time, since the insertion opening door 32 is set to a size that does not protrude from the mask surface 20a, it is not easily damaged by an external force. Further, since the shaft member 31 is thin and easily deformed, the shaft member 31 is effectively prevented from being deformed by being supported from above and below by the four spring support portions 35 via the spring 33.
[0014]
As described above, in the present embodiment, the insertion port door 32 can be rotated 180 degrees around the single shaft member 31, so that the structure is simple and the cost can be reduced.
[0015]
【The invention's effect】
As described above, according to the first aspect of the present invention, the insertion slot door can be rotated approximately 180 degrees around a single axis portion to open and close the bill insertion slot. The number of parts can be reduced and the cost can be reduced as compared with the conventional insertion port opening / closing mechanism having the.
