Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a medium positioning mechanism that also serves as a width adjusting mechanism for transporting media having different widths to a predetermined position, such as a passbook used in an automatic transaction apparatus of a financial institution.
[0002]
[Prior art]
In an automatic transaction apparatus installed in a financial institution or the like, in order to read and print a magnetic stripe provided on a medium such as a passbook, a width adjusting mechanism that abuts the medium against a reference surface is mounted.
This width-shifting mechanism is to straighten the medium by pushing the medium against the reference surface by a clamp arm or the like from the opposite side to the reference surface provided on one side in the medium transport direction. The medium is transported in a direction perpendicular to the abutting direction, and after stopping at a predetermined position, a printing operation or the like is performed.
[0003]
[Problems to be solved by the invention]
However, in the conventional media width adjusting mechanism, due to a difference in the thickness or length of the medium to be handled, after the width is adjusted, the operation is performed while the medium is transported to the printing position in the direction perpendicular to the width adjusting movement direction. There has been a problem that the end face of the medium is distorted due to being carried or conveyed while the pressed medium is bent.
[0004]
For example, in Japanese Patent Application Laid-Open No. 11-11746, after the medium is width-adjusted by the width-adjusting member and clamped by the conveying roller, the medium is conveyed after returning the width-adjusting member. Since the width adjusting member is returned, the deflection of the medium is released and the edge of the medium is not deviated. However, it is expected that the medium deviates from the abutting reference during conveyance, and normal printing cannot be performed. There was a problem. The present invention aims to realize a medium positioning mechanism that solves both of these problems.
[0005]
[Means for Solving the Problems]
This is a medium positioning mechanism on the transport path, and the medium is moved in the direction perpendicular to the transport direction by pressing the medium from the opposite side of the transport reference plane and the transport reference surface on one side of the medium transport direction. The media pressing guide, the bump detection sensor provided on the transport reference surface side that detects that the medium is pressed against the transport reference surface, and the media received from the insertion port of the transport path. Medium pressing guide driving means for driving from the standby position until detection by the abutting detection sensor and holding the transport position returned from the pressing position to a predetermined width.
[0006]
As a result, the passbooks having different widths can be surely brought closer, and the passbook being conveyed to the printing position can be prevented from being skewed and positioned correctly, and the passbook end face can be prevented from being loosened.

FIG. 2 is a side view corresponding to FIG. 1, and shows a state in which the medium pressing guide 3, the pressing guide drive motor mounting member 5, the pulse motor 7, the motor bearing gear 8, and the like are assembled from the side. Laura.
FIG. 3 shows an outline of the unitary structure of the pressing guide 3, in which a horizontal plane and a right end vertical plane are integrally formed, a hollow notch 12 is provided at a central portion of the horizontal plane, and a gear is provided at one end thereof. The rack 9 which meshes with is engraved. Further, four shafts 13 are fixed at positions near the four corners of the upper surface.
[0010]
FIG. 4 shows a schematic structure of a single unit of the pressing guide drive motor mounting member 5. At four corners, screw holes for mounting are formed in bent portions in order to fix the supporting side surface 6 of FIG. In addition, a long and narrow slide groove 14 is cut at two positions on the front and back of the drawing on the horizontal plane, so that one set of two shafts of the media pressing guide can move left and right along this groove. It has become.
[0011]
Next, as shown in FIG. 2, the front and back shafts on the upper surface of the medium pressing guide 3 have a set of two shafts on the front side and the rear side of the narrow guide groove of the pressing guide drive motor drive member. The medium pressing guide 3 is supported in such a manner as to hang from the pressing guide drive motor drive mounting member 5 by fitting the E ring 15 into the E groove cut on the side surface of the shaft after the groove 14 is fitted. It can move freely along the slide groove 14 from side to side.
[0012]
Further, a part of the horizontal surface of the medium pressing guide 3 is cut into a rectangular shape, and a rack 9 is provided at one end of the notch 12 of the hollow portion, while a pulse motor is provided on the horizontal surface of the pressing guide drive motor mounting member 5. 7 and the motor bearing gear 8 are attached, and the medium pressing guide 3 is driven by meshing with the rack 9.
The medium pressing guide 3 presses the medium from the standby position (home position), which is the maximum width, from the opposite side of the conveyance reference side surface 2, aligns one side of the medium 4 with the reference side surface 2, and the distance from the reference side surface 2 is the medium. A position where the width is equal to or smaller than the width of 4 and a position where the medium pressing guide 3 is returned and a position which is equal to or slightly wider than the width of the medium 4 is set as a predetermined width as the transport position. It can be stopped at each position. Here, when assuming a bankbook of a financial institution as a medium, the predetermined width is considered to be, for example, a length of about +0.5 mm for the width of the bankbook, and the setting up to about +1.5 mm can be driven and controlled by a pulse motor. To do. After the medium is set at the reference position in the left-right direction, the medium is sandwiched between the upper and lower transport rollers 16 in the transport path and driven in the front-rear direction.
[0013]
FIG. 5 is an enlarged view of the medium abutting detection unit. The pressing position indicates that the medium 4 has been pressed against the conveyance reference side surface 2 by the medium pressing guide 3, and the abutting detection member 10 attached to the conveyance reference side surface 2 is pressed against the medium, causing the abutting detection sensor 11 to be pressed. By being inserted and blocking the light, the driving of the pulse motor 7 is stopped.
Next, the operation of the above configuration will be described. When the medium 4 is set at the home position of the transport path 1 from the insertion port, the medium pressing guide 3 waiting at the standby position is moved to the pressing guide drive motor mounting member 5. The attached pulse motor 7 is driven to engage with the rack 9 through the motor bearing gear 8 to move the medium 4 to the pressing position. As a result, the medium 4 is bent and its one end face comes into contact with the reference side face 2 to correct the skew. Next, by driving the pressing guide drive motor in the reverse rotation direction, the medium pressing guide 3 is moved to a transport position that is the same as or slightly wider than the width of the medium 4 and stopped. As a result, the bending of the medium 4 is eliminated, and the skew and right / left positions of the medium are corrected to obtain a normal state.
[0014]
Thereafter, the medium is transported to the printing position by the transport roller 16 and returns to the original position after the printing is completed. During this time, the medium pressing guide stops at the transport position. At the same time as the medium is ejected, the medium pressing guide returns to the standby position, whereby the medium width adjusting operation of the medium 4 is completed.
[0015]
【The invention's effect】
As described above, according to the present invention, the medium pressing guide driving means reliably moves the media of different widths, and the pressing guide is moved in the reverse direction by the amount of bending by which the flexible medium is pressed excessively. Until the medium is transported to the print position, the pressing guide also serves as the transport path and maintains the same position, so that the transport path width is maintained optimally, and the medium rebounds after the width is adjusted. Therefore, the transport load is reduced, the skew of the medium being transported can be prevented, and there is no deflection of the medium. Can be realized.
