Description

media processing device

The present invention relates to a media processing device that puts the media to be processed such as passbooks into the insertion port of the device, and the media is transported to a printing position and processed by printing.

In the existing media processing device, once the media is put into the conveying path entrance of the device, it is automatically conveyed to the printing position by the conveying roller. However, in this case, there is a problem that when the medium is put in obliquely, since it is conveyed while being oblique, printing is also performed obliquely. In this regard, Japanese Patent Application Laid-Open Publication No. 6-71961 discloses a technique in which an optical sensor detects irregularities in a sheet of paper, and a roller rotates to adjust the sheet of paper against a guide rail, thereby adjusting the medium to be aligned with the guide rail. The printing direction is parallel. In addition, in Japanese Patent Publication No. Sho 61-206680, a technique is disclosed, that is, as a mechanism for conveying a medium, before magnetic reading, there are two media on the same axis in a direction at right angles to the medium insertion direction. A roller mechanism that moves the media closer to the guide rails, and the media is transported in parallel to the printer position. In addition, in the device described in Japanese Patent Application Laid-Open No. 1-242355, there is disclosed a technology that selectively nips and releases the media to the discharge rollers outside the device. In addition, in the device described in Japanese Patent Application Laid-Open No. Hei 5-201078, the lateral movement wheel arranged as a mechanism for transporting the medium operates along a direction at right angles to the reference guide rail and in the medium thickness direction. The upper also acts in the direction of depressing the medium to push the recording medium against the reference rail prior to magnetic reading. In addition, in the passbook processing device described in International Publication No. 9812052, as a printer with an adjustment mechanism, a mechanism for adjusting the inclination of the medium is provided by controlling the rotation of the loaded medium around a certain static point. . Here, the rotation control mechanism is arranged on the left and right, and the rotation in two directions is performed by turning right and turning left. That is to say, this mechanism for adjusting the media is equipped with a metal arm protruding from the center of rotation, and a soft material installed at its front end to give the media friction and move the media closer to the horizontal guide rail. The rotating arm, the motor that rotates the rotating arm, and the belt that connects the motor and the rotating arm and transmits the rotational driving force, since the rotating arm rotates in the counterclockwise direction, it interferes with the pressing guide rail of the pressing medium and the pressing guide rail moves upward. The medium is adjusted to a certain position due to the friction force of the material at the front end of the arm moving closer to the horizontal guide rail.

Among the conventional media processing devices described above, the device described in Japanese Patent Application Laid-Open No. Hei 6-71961 has a complicated structure for adjustment. In addition, although the device described in Japanese Patent Application Laid-Open No. Hei 1-242355 is effective for continuous paper processing on rollers, it cannot move cut paper such as passbooks or vouchers closer to the direction of the horizontal guide rail. And Japanese Patent Application Laid-Open No. 61-206680 communique and the device described in Japanese Patent Laid-Open No. 5-202078 communique, for such long summons of A4 size, be difficult to move near horizontal guide rail in a short time. In addition, in the passbook processing device described in International Publication No. 9812052, complex mechanism control is performed, and there is a problem in the media adjustment mechanism.

The object of the present invention is to provide a media processing device that can adjust these media to a certain level of the reference guide rail in a short time with a simple structure even when media of various lengths and thicknesses are placed in the device. position, followed by media inhalation.

In addition, another object of the present invention is to provide a book processing device capable of adjusting media according to the type of media being transported.

In order to achieve the above object, the media processing device of the present invention is equipped with at least one pair of conveying rollers that clamp the inserted medium and convey it, and a printer that prints on the medium conveyed by the conveying rollers is used to control the media conveyed by the aforementioned conveying rollers. The reference guide rail at the end of the medium conveyed by the roller is arranged near the reference guide rail, and the horizontal sensor for detecting the presence or absence of the aforementioned medium in the vicinity of the reference guide rail has an elastic body in a protruding shape, so that the aforementioned media moves toward the aforementioned reference guide rail. A plurality of shifting rollers moved closer to one side, a release lever for releasing the gripping of the medium by the conveying rollers, and when the medium is not detected by the lateral sensor after the medium is inserted, the releasing lever is controlled to release the conveying The clamping of the aforementioned media by the rollers, the control circuit that controls the aforementioned shifting rollers to move the aforementioned media closer to the side of the aforementioned transverse guide rail; and the aforementioned plurality of shifting rollers are arranged at different distances from the aforementioned reference guide rail, and the rotation phases are different .

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Although the media processed by the media processing device in the present invention mainly include booklet-like folded things such as passbooks, or ordinary ordinary paper such as receipts, in this embodiment, a passbook will be used as an example to describe .

Fig. 1 is an external view of a passbook processing device as an embodiment of the present invention viewed obliquely from the front, and further shows a partial internal perspective view.

In FIGS. 1 and 2 , the passbook 6 is aligned with the conveyance path formed by the upper conveyance path 5 and the lower conveyance path 3 , is inserted from the front insertion port 36 of the passbook processing device 40 , and is conveyed in the direction of the arrow 38 .

The conveying rollers for conveying are made of elastic body such as rubber, and are composed of A driving roller 13 and B driving roller 16 contacting from below the passbook 6, and pressing rollers 11, 33 contacting from above the passbook 6. In addition, the passbook 6 is conveyed to the printer 14 for printing processing by being sandwiched between the A driving roller 13 and the pressing roller 11 .

The reference guide rail 4 is provided so as to align the ends of the passbook 6 being transported, which are parallel to the insertion direction. In addition, as a sensor for detecting the inserted or transported passbook 6, there is a horizontal sensor 7 arranged near the reference guide rail 4 to detect whether there is a passbook 6 near the reference guide rail 4, and a front sensor 8 for detecting whether the passbook 6 is conveyed to the front. The presence/absence sensor 26 which detects whether the passbook 6 is inserted. Each sensor detects the presence of a passbook when it is dark, and detects the absence of a passbook when it is bright.

FIG. 2 shows an internal configuration diagram of the passbook processing device 40 . The passbook 6 is inserted through the insertion port 36, and is conveyed along the conveyance path composed of the lower conveyance path 3 and the upper conveyance path 5 shown in FIG. 1 (direction of arrow 38 in FIG. 1). Through the clamping of the A driving roller 13 and the pressing roller 11, and the clamping of the B driving roller 16 and the pressing roller 33, the rotational power is transmitted to the passbook 6 by the friction between the passbook 6 and each roller, thereby carrying out the delivery of the passbook 6 . The A driving roller 13 and the B driving roller 16 are connected with the conveying motor 31 via the belt 32, the power of this conveying motor 31 is transmitted to the A driving roller 13 and the B driving roller 16, and the rotational power is transmitted to the bankbook 6 so that the bankbook 6 is transport.

Between the insertion opening 36 and the A drive roller 13, the presence/absence sensor 26 for detecting presence/absence of the passbook 6 is provided. 1 and 2 , when the passbook 6 covers the presence/absence sensor 26 from the insertion opening 36 , the presence/absence sensor 26 detects the passbook 6 . As soon as the presence sensor 26 detects the passbook 6, the control circuit 27 described below drives the transport motor 31 based on this detection signal. Thereby, the passbook 6 is transported in the direction of the arrow 38 in FIG. 1 , that is, from the left side (front of the passbook processing device 40 ) to the right side (rear of the passbook processing device 40 ) in FIG. 2 .

Likewise, a front sensor 8 is provided between the A drive roller 13 and the print head 14 . When the passbook 6 conveyed from the insertion opening 36 passes through the installation position of the front sensor 8, the front sensor 8 detects the passbook 6. When the passbook 6 is detected by the front sensor 8, the control circuit 27 (refer to FIG. 6 ) described below stops the transport motor 31 . At this position, although the passbook 6 is clamped by the A driving roller 13 and the pressing roller 11 , it is not clamped by the B driving roller 16 and the pressing roller 33 .

FIG. 3 is a mechanism diagram of the roller lifting mechanism 35 that releases the pinching of the passbook 6 by the pressing roller 11 and the drive roller 13 in the passbook processing device 40 . In FIG. 3 , the roller lifting mechanism 35 shows a state in which the passbook 6 is sandwiched between the pressing roller 11 and the driving roller 13 . The pressing roller 11 is attached to a shaft 12 extending in the lateral direction of the passbook processing device 40 . In addition, a release lever 9 with a D-shaped cut surface 9 a is installed along a direction perpendicular to the shaft 12 . As shown in FIG. 5 , a D-shaped cut surface 9 a , which is a part of the release lever 9 , is arranged to come to the lower side of the shaft 12 . Release lever 9 is connected to electromagnet 18 via pulley 17 by steel wire rope 10. As soon as the electromagnet 18 is energized, the steel rope 10 is stretched, and the release lever 9 connected with the steel rope 10 rotates in the direction of the arrow 22 (counterclockwise). Once the release lever 9 rotates, the D-shaped cut surface 9a as a part of the release lever 9 also rotates counterclockwise, and the D-shaped cut surface 9a lifts the shaft 12 on which the pressing roller 11 is installed. In this way, the clamping of the passbook 6 by the pressing roller 11 and the driving roller 13 is released.

4A, 4B, 4C, and FIGS. 5A and 5B are structural diagrams of the media shifting mechanism 34 for adjusting the inclination of the passbook 6 in the passbook processing device 40 . The medium displacement mechanism 34 is produced by the displacement rollers 1, 2 of elastic bodies (rubber, etc.) with protruding shapes that transmit the frictional force to the passbook 6 and make the passbook 6 move closer to the reference guide rail 4, and are used to make these displacements The motor 20 of the rotational driving force for the rotation of the rollers 1 and 2, the gear train 37 for power transmission between the shift rollers 1 and 2 and the motor 20, and the position sensor 21 for detecting the number of rotations of the shift rollers 1 and 2 constitute . There are two shifting rollers 1, 2 in this embodiment, and the installation distances of these to the reference guide rail 4 are different, and the rotation phases of the elastic bodies in the shape of protrusions in contact with the passbook 6 are different. These two points are structural features in the present invention.

In addition, the passbook 6 is always pressed against the lower conveying path 3 with a weak force by the pressing ball 36a. The pressing ball 36 is configured to be movable up and down.

Here, since the elastic bodies of the shift rollers 1 and 2 on the lower conveying path 3 contact the passbook 6, a concave shape 38a is formed, so they contact the passbook 6 in a slightly bent state. By bending the elastic body in this way, a stable media displacement force can be generated even for various media such as thick bankbooks and thick and thin slips. That is to say, there is such an effect that, for media with strong rigidity (such as passbooks with a thick thickness), the displacement force of the media is suppressed by bending the elastic body, and for media with low rigidity (such as vouchers with weak rigidity) , by flexing the elastomer, and the subpoena also flexes to suppress the media displacement force. In this way, by suppressing the medium displacement force to a low value, there is an effect of eliminating jamming due to excessive displacement.

Next, FIGS. 4B and 4C show phase diagrams of shift rollers. After the position sensor 21 detects the shift roller at the position of the shift roller of FIG. 4B , the bankbook 6 is moved in the lateral direction at the position of FIG. 4A , and the approaching action is ended at the position of the shift roller of FIG.

In addition, FIG. 5A is a plan view of FIG. 4A. FIG. 5A shows that the displacement roller 1 of the medium displacement mechanism 34 is disposed closer to the reference rail 4 than the displacement roller 2 . In addition, because the rotation phase of the displacement roller 1 and the displacement roller 2 differs by a predetermined value, for example, first the displacement roller 1 acts on the passbook 6 to become the state (I) of FIG. Become (II) state of Fig. 5B, so can more effectively carry out the adjustment to reference guide rail 4 of the long media etc. of lengthwise direction, as shown in Fig. 5B, can produce displacement force so that be in the bankbook of A state can become The state of B and C.

FIG. 7 shows the workflow from insertion of the passbook 6 into the passbook processing apparatus to completion of the approaching operation, and FIG. 8 is a diagram showing a condition table of the driving speed of the motor 20 of the medium shift mechanism 34 .

First, when the horizontal sensor 7 detects the passbook 6 (step 701), since the passbook 6 is normally put in along the reference guide rail 4, the shift rollers 1 and 2 do not start, and the passbook is not adjusted. In addition, when the passbook is put into proficiency, that is, as a result of several times of learning to put the passbook into the suction port, if it is put in under the normal state, if there is an instruction not to use the adjustment part 34 (step 701), the same procedure is performed. processing. When the passbook 6 is not detected by the horizontal sensor 7, or there is no start indication of the adjustment unit 34, the electromagnet 18 shown in Fig. 3 is energized (step 702), because the steel wire rope 10 shown in Fig. 23 directions are stretched, so release lever 9 and rotate toward arrow 22 directions. By the rotation of the release lever 9, the D-shaped cut portion 9a of the release lever 9 is also rotated, and the shaft 12 becomes a lifted state at the corners of the D-shaped cut surface. Therefore, since the shaft 12 is pushed up toward the arrow 21, the pressing roller 11 attached to the shaft 12 is also pushed up. Through this action, the clamping of the passbook 6 by the pressing roller 11 and the driving roller 13 is released.

When the pressing roller 11 is lifted, the motor 20 is driven (step 703), and this power is transmitted to the shift rollers 1 and 2 through the gear train 37, and the shift rollers 1 and 2 rotate clockwise. At this time, the passbook 6 is detected by the horizontal sensor 7 (step 704 ), which shows that the left end of the passbook 6 moves closer to the reference guide rail 4 .

Next, by the position sensor 21 installed near the displacement rollers 1, 2, the passing of the protrusions of these displacement rollers 1, 2 is detected (step 705), and the control circuit 27 mentioned below confirms that each time the rollers move The rotation is over. Therefore, the horizontal sensor 7 and the position sensor 21 respectively detect the passbook 6 and the shift rollers 1, 2, and the information is notified to the control circuit 27, and the motor 21 is stopped according to the instruction from the control circuit 27 (step 706). Furthermore, the electromagnet 18 shown in FIG. 3 becomes de-energized (step 707). The state of this step 707 is a state in which the passbook moves closer to the reference guide rail 4, and the passbook 6 is clamped by the pressing roller 11 and the A driving roller 13.

In addition, as shown in FIG. 8, by changing the driving speed of the motor 20 according to the rigidity of the inserted medium, thereby adjusting the medium displacement force, it is possible to move closer to the reference rail efficiently. For example, in the case of a passbook (A in the figure), a strong displacement force is applied by making the speed high, and in the case of a small slip (B in the figure), for example, the displacement force is set to a medium level by setting the speed at a medium level. For example, in the case of a large bill (C in the figure), the displacement force is suppressed by bending the elastic bodies of the displacement rollers 1 and 2 at a low speed. The specification of the driving speed of the motor 20 may also be specified by inputting from an input mechanism not shown (for example, a keyboard, a touch panel, etc.).

Moreover, as shown in FIG. 8, if the driving speed conditions of the motor 20 are tabulated in advance, the speed most suitable for the processing medium can be selectively implemented, and the movement to the reference guide rail 4 more suitable for the medium actually used can be realized. close action. It is also possible to store this table in advance in an unillustrated storage unit of the control circuit 27 so that the drive speed of the motor 20 can be determined in correspondence with the speed input and specified by the above-mentioned input means.

If the adjustment of passbook ends, then passbook 6 is transported to the printing position of printer 14, after printing, transport motor 31 is driven along with the opposite direction when passbook 6 is inserted, thereby passbook 6 is moved towards the insertion port 36 of Fig. 2 Direction delivered and discharged.

Fig. 6 is a block diagram of the control system of the passbook processing device in Fig. 1 . A control circuit (for example, CPU) 27 receives respective detection outputs from the lateral sensor 7, the front sensor 8, the presence/absence sensor 26, and the position sensor 21, and outputs control instructions corresponding to them. That is, when the passbook 6 is detected by the presence/absence sensor 26 , the control circuit 27 controls the transport motor drive circuit 28 to drive the transport motor 31 . When the horizontal sensor 7 does not detect the passbook, the control circuit 27 controls the electromagnet drive circuit 30 to start the electromagnet 18 to release the clamping force of the passbook 6, and controls the motor drive circuit 29 to start the motor 20 simultaneously.
