Description

  The present invention relates to a medium processing apparatus having a width adjusting mechanism for positioning a medium when a paper sheet medium is conveyed.

Some medium processing apparatuses perform printing, reading / writing of magnetic data, and the like on a medium.
In such a medium processing apparatus, the printing position and magnetic data writing position are determined from the upper end or lower end, the left end or the right end of the medium, so that printing is performed at an accurate position or reading / writing of magnetic data is performed. In this case, it is necessary to accurately position the medium with respect to the print head or the magnetic head.

Generally, positioning in the vertical (front-rear) direction is performed by controlling the conveyance position of the medium, and positioning in the orthogonal direction is performed by abutting the medium against a reference surface provided on the side surface of the conveyance path. .
For this reason, a medium processing apparatus that performs printing or reading / writing of magnetic data includes a width adjusting mechanism that determines a position in a direction orthogonal to the medium conveyance direction. In general, the width adjusting mechanism 100 is disposed in the middle of the conveyance path 101 as shown in FIG. 6 (see, for example, Patent Document 1 and Patent Document 2).

  In addition, the width adjusting method of the width adjusting mechanism includes (1) a method in which the roller provided in the conveyance path is raised and the side surface of the medium is struck to abut the medium against the reference surface, and (2) provided in the conveyance path. (3) A method in which the medium side is abutted against the reference surface by transporting the medium longitudinally and laterally by the roller in the width adjusting mechanism. (4) A system in which the side surface of the medium is abutted against the reference surface by the inclined surface provided by the tapered roller provided in the width adjusting mechanism, and (5) the inclined surface supplied by the roller provided in an inclined manner in the width adjusting mechanism. There is a method of abutting the side surface of the medium with the reference surface.

In these methods, generally, a sensor is used to monitor whether or not the medium has hit the reference surface, and when the sensor satisfies the setting condition, the processing is completed as a width adjustment OK.
In the above methods (1) and (2), when it is determined that the medium does not hit the reference surface (width alignment NG), a retry process is possible. If it is determined that they are abutting (width alignment OK), the width alignment processing is completed and transported to the next process.

When the specified number of retries is over due to the width adjustment NG, processing such as returning or taking in the medium is performed, and printing or reading / writing of magnetic data is not performed. Therefore, the process for this medium is not established.
In the methods (3), (4), and (5), the width adjusting process is performed by passing through the width adjusting mechanism from one direction. If the medium is not completely aligned (width alignment NG), the transport direction is reversed for retry, and the width alignment mechanism is passed from the opposite direction. I will return. Therefore, even if it passes through the width adjusting mechanism for the second time, only the same processing as that for the first time is performed, and the width adjustment is not achieved and the result is NG.

In the above-described conventional techniques (3), (4), and (5), when the width adjusting mechanism becomes NG after passing through the width adjusting mechanism from one direction, the width adjusting process is performed by passing the width adjusting mechanism again. There is a problem that you can not do.
An object of the present invention is to solve such a problem.

  Therefore, the present invention is a medium processing apparatus in which a width adjusting mechanism for determining a position in the (right and left) direction orthogonal to the medium conveying direction is arranged in the conveying path, and is in a loop shape returning from the rear of the width adjusting mechanism to the preceding conveying path. It is characterized in that a circulating conveyance path is provided.

  According to the present invention, a width adjusting mechanism is provided in the circulation conveyance path, and the medium of the width adjustment NG is conveyed in one direction, and returned to the circulation conveyance path again so that the width adjustment processing can be performed. An effect is obtained that it is possible to retry a plurality of width adjusting processes.

  Embodiments according to the present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory diagram illustrating the first embodiment.
In the figure, there are a first transport path 1 through which a medium inserted from an insertion port (not shown) is transported in the direction of arrow A and a second transport path 2 to transport to the next process. A circulating conveyance path 3 is provided in a loop shape (the same structure is obtained even if the loop-shaped circulation conveyance path 3 is connected to the first conveyance path 1). A switching blade 5 is provided at a branching portion 4 between the first conveyance path 1 (circulation conveyance path 3) and the second conveyance path 2. By this switching blade 5, one is the conveyance path 2 and the other is circulation. It switches to the conveyance path 3. The conveyance path 2 conveys the medium in the direction of arrow B and delivers it to the next step, and the circulation conveyance path 3 is a route that conveys the medium in the direction of arrow C and leads to the junction 6 of the preceding conveyance path 1.

A width adjusting mechanism 7 is provided in the first conveyance path 1 (circulation conveyance path 3). The width adjusting mechanism 7 provided here may be any type of width adjusting mechanism.
According to such a configuration, the medium that has been transported in the direction of the arrow A along the first transport path 1 passes through the merging portion 6 to the width adjusting mechanism 7 of the first transport path 1 (circulation transport path 3). It is conveyed and a width adjustment process is performed. Here, when it is determined that the width adjustment is OK by a sensor (not shown) in the width adjustment mechanism 7, the switching blade 5 is switched to the direction of the broken line and the medium is conveyed in the direction of arrow B of the second conveyance path 2. , Passed to the next step.

When it is determined that the width is shifted NG, the switching blade 5 is switched to the direction of the solid line shown in the figure, and the medium is transported in the direction of the arrow C of the circulation transport path 3 and returns to the junction 6.
Again, the medium is transported to the width adjusting mechanism 7 to perform the width adjusting process, and it is determined by the sensor whether the width adjusting process is OK or NG. In the case of width alignment OK, the switching blade 5 is returned to the direction of the broken line, and the conveyance path 2 is conveyed in the direction of arrow B. In the case of width alignment NG, it is conveyed again to the circulation conveyance path 3 and a series of retries is repeated.

Note that the number of retries is set in advance, and if it does not result in a width adjustment even after repeating the specified number of times, the retry is stopped and the medium is returned as an abnormal medium to complete a series of processes. .
According to the present embodiment described above, the width adjusting mechanism is provided in the conveyance path (in the circulation conveyance path), and the medium of the width adjustment NG is returned to the conveyance path through the circulation conveyance path so that the width adjustment process can be performed again. This has the effect that it is possible to retry a plurality of width adjusting processes.

2 and 3 are explanatory views showing the second embodiment.
The first embodiment has a configuration in which the position of the width adjusting mechanism 7 in the circulation conveyance path 3 is positioned at a position before the switching operation of the switching blade 5. In this embodiment, the width adjustment mechanism 7 in the circulation conveyance path 3 is arranged. In this configuration, the position of the mechanism 7 is located at a position after the switching operation of the switching blade 5.
In the figure, a medium inserted from an insertion port (not shown) is transported in the direction of arrow A, and between the first transport path 1 where the monitoring sensor 8 is arranged and the second transport path 2 transported to the next process. A loop-shaped circulation conveyance path 3 is provided, and a switching blade 5 is provided at a branching portion 4 between the circulation conveyance path 3 and the conveyance path 2. With this switching blade 5, one is a conveyance path 2 and the other is a circulation conveyance. It is designed to switch to road 3. The conveyance path 2 conveys the medium in the direction of arrow B and delivers it to the next step, and the circulation conveyance path 3 is a route that conveys the medium in the direction of arrow C and leads to the junction 6 of the preceding conveyance path 1.

A width adjusting mechanism 7 is provided in the circulation conveyance path 3. The width adjusting mechanism 7 provided here may be any type of width adjusting mechanism.
According to such a configuration, the medium conveyed to the conveyance path 1 passes through the monitoring sensor 8 and determines whether the width is adjusted OK or NG.
When the monitoring sensor 8 determines that the width adjustment is OK, the switching blade 5 is switched to the broken line state as shown in the drawing, the medium is conveyed in the direction of arrow B of the conveyance path 2, and is transferred to the next step.

If the monitoring sensor 8 determines that the width is shifted NG, the switching blade 5 is switched to the solid line state as shown in the figure, and the medium is transported in the direction of the arrow C of the circulating transport path 3. The sheet is conveyed to the shifting mechanism 7 and a width shifting process is performed. Whether the width adjusting process is OK or NG is determined by a sensor (not shown) in the width adjusting mechanism 7.
The medium is transported to the branching section 4 when the above determination is either OK or NG. In the case of OK, the switching blade 5 is switched to the direction of the broken line, and the medium is moved in the direction of arrow B of the transport path 2. It is conveyed and delivered to the next process.

  When it is determined that the width is shifted NG, the switching blade 5 is switched to the direction of the solid line, the medium is transported in the direction of the arrow C of the circulating transport path 3, and the medium is transported again to the width shifting mechanism 7 of the circulating transport path 3. Then, the width adjusting process is performed, and it is determined by the sensor whether the width adjusting process is OK or NG. In the case of width alignment OK, the conveyance path 2 is conveyed in the direction of arrow B, and in the case of width alignment NG, a series of retries in which the width alignment process is performed by being conveyed again to the width alignment mechanism 7 of the circulation conveyance path 3 is repeated.

Note that the number of retries is set in advance, and if it does not result in a width adjustment even after repeating the specified number of times, the retry is stopped and the medium is returned as an abnormal medium to complete a series of processes. .
In the above configuration, the monitoring sensor 8 does not have to be arranged in the conveyance path 1, and in that case, the width adjusting mechanism 7 provided in the circulation conveyance path 3 is always passed by passing the circulation conveyance path 3 once. Thus, the width alignment OK and NG can be monitored by a sensor (not shown) in the width alignment mechanism 7, and a retry can be performed when the width alignment is NG.

  According to the above-described embodiment, the monitoring sensor 8 is arranged in the conveyance path 1 and the position of the width adjusting mechanism 7 in the circulation conveyance path 3 is located at a position after the switching operation of the switching blade 5. Since the medium judged to be width-aligned by the monitoring sensor 8 is transported to the transport path 2 without passing through the width-spacing mechanism 7 and delivered to the next process, the transport distance can be shortened to shorten the processing time. it can.

Further, since the width adjusting process is not performed on the medium whose width is OK, the medium is not damaged during the processing.
Further, even when the monitoring sensor 8 is not provided, by arranging the width adjusting mechanism 7 in the circulation conveying path 3, the direction of the width adjusting mechanism 7 can be freely arranged with respect to the entire conveying directions A and B. Can do.

4 and 5 are explanatory views showing the third embodiment.
In the present embodiment, the width adjusting mechanism is configured in a curved shape, and the width adjusting mechanism 7 is configured in a curved shape, without being limited to the circulation conveying path or the conveying path. The shape of the conveyance path at the place where the width adjusting mechanism 7 is arranged is also a curved shape including an annular shape.
The arrangement position of the width adjusting mechanism is the same as that in each of the embodiments described above, and accordingly, the medium transport operation is also as described above.

According to the above-described embodiment, the medium is curved along the curved shape of the width-shifting mechanism during the width-shifting process by the width-shifting mechanism. It becomes difficult to bend compared to the shape, and the medium can be surely made wider.
Further, by making the width adjusting mechanism in a curved shape, the length of the width adjusting mechanism can be shortened, and the conveying path is also shortened in a curved shape, so that the apparatus can be miniaturized.

  In this embodiment, the medium is described as being conveyed from the direction of arrow A to the direction of arrow B. However, the present invention is not limited to this, and the medium is conveyed from the direction of arrow B to the direction of arrow A, and the width is similarly adjusted. You can also. In this case, a switching blade is required on the merging portion side.
