DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stamping device for stamping a stamp or a bill (hereinafter referred to as "stamp") attached or printed on a conveyed postal matter, and more particularly to a paper stamping device. It is possible to imprint over a wide range of leaves,
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet stamping device capable of stamping while avoiding a destination portion.

[0002]

2. Description of the Related Art Conventionally, even when a portion to be stamped of a conveyed sheet is present at a position slightly deviating from a predetermined range, the sheet is accurately rejected without being rejected. There has been a paper sheet stamping apparatus capable of stamping a sheet (for example, Japanese Utility Model Laid-Open No. 59-162273).

[0003] This conventional sheet stamping apparatus will be described with reference to FIGS. 9 and 10.

First, a two-dimensional image input unit 102 detects the leading end of a sheet 113 conveyed on the conveying path 101 by a photoelectric sensor (not shown), and detects the leading end of the sheet 113 at the detected timing. Enter image data. Then, the fee amount stamp surface detection unit 103 detects the position of stamps on the paper sheet 113,
The number, type, etc. of the stamps are detected, the sticking position information of the stamps is determined, and the sticking position information is stored in the register 301.

Next, the leading end of the sheet 113 passing through the two-dimensional image input unit 102 is detected by the photoelectric sensor 106, and the moving time of the sheet 113 from the photoelectric sensor 106 is counted by the counter circuit 107. The photoelectric sensor 106 and the position where the sheet 113 is to be stamped by the stamper 111 are set in advance.
01 and the counter circuit 10
7 based on the movement time counted in step 7
Is determined. The stamper driving circuit 109 operates at the determined driving timing, and the sheet 113 is accurately stamped by the stamper 111 at the position where the stamps are attached.

Here, the stamping device 111 is a rotary stamping means as shown in FIG. That is, the shaft member 304
, A cylindrical marking member 303 having an imprint formed thereon is attached thereto, and this shaft member is connected to a rotation driving means such as a motor (not shown). The rotation driving means rotates the cylindrical marking member 303. It is a rotary hub type that stamps and stamps.

[0007]

The width and length of the postmarks for postmarking stamps affixed on paper sheets are determined to be optimum values in view of the size of the stamps, legibility of human beings, and the like. Therefore, the size of the stamper is naturally limited.

In the conventional sheet stamping apparatus, the stamping range where stamping can be performed in the short side direction of the sheet is, as shown in FIGS. 10 and 11, from the lower end of the conveying path 101 to the stamping device. Due to the fixed distance C up to 111 and the width of the stamping device limited by the width D of the postmark mark, it is limited to the range A.

Further, the stamping range of the stamps which can be stamped in the long side direction of the paper sheet is controlled by controlling the stamping device so that the postmark can be applied to the stamps even if it is a little. Even if the change is dealt with, the length E is substantially limited to the range B because the length E of the postmark mark is limited.

Therefore, stamps pasted in a range other than the range A cannot be stamped in the short side direction of the paper sheet, and the stamps in the long side direction of the paper sheet fall in the range B. There is a problem that stamp processing cannot be performed on stamps pasted in a range other than the range B if at least one is pasted.

[0011] Further, simply trying to expand the range in which a stamping process can be performed on a sheet using a plurality of stamping devices, address information or the like is described on the sheet. Postmark marks overlap. Therefore, there is a problem that it is very difficult to perform a process of automatically sorting sheets based on the destination information.

[0012]

Further, the address detection unit 104 detects the presence / absence of address information described on the sheet 113, the described position (address location information), and the like based on the image data input by the two-dimensional image input unit 102. Then, it outputs the address position information to the position information detection unit 105. The position information detection unit 105 detects a stampable area on the paper sheet 113 avoiding the address portion based on the stamp position information and the address position information, and determines a stamp position on the paper sheet 113. Then, it outputs the stamp position information on the stamp position to the stamp control unit.
The counter circuit 107 is configured such that the photoelectric sensor 106
The counting is started at the timing of detecting the tip of No.3.

A method of detecting stamps, a method of detecting stamps by detecting a color frame of the stamps, and, for stamps having phosphorescence / fluorescence characteristics, detecting the phosphorescence / fluorescence characteristics. Accordingly, a method of detecting stamps or the like is used, but any of the methods is a well-known means, and a detailed description thereof will be omitted. In addition, in order to detect all kinds of stamps without fail, it is conceivable to use a plurality of stamps and fee stamp detecting means together with the above three detecting means.

As the address detecting unit 104, for example, a method disclosed in Japanese Patent Publication No. Hei 5-1074 can be used. In this method, information such as a character string is divided into blocks based on input image data under certain conditions.
Then, the obtained block is scored based on a predetermined address reliability determination requirement to detect the address position. Here, the address position information detected by the address detection unit 104 and the stamp position information detected by the fee amount stamp surface detection unit 103 are indicated by xy coordinate values based on the circumscribed frame of the paper sheet 113. Can be.

As shown in FIG. 2, a plurality of stamping devices 111 and 112 of a rotary hub type are installed at different heights in the direction perpendicular to the direction in which the sheets 113 are conveyed. The stampers 111 and 112 are independently driven and controlled by the stamper driving circuits 109 and 110.

Next, the operation of the first embodiment will be described with reference to the drawings.

First, when a sheet 113 is conveyed along the conveyance path 101, it passes through the two-dimensional image input unit 102. In the two-dimensional image input unit 102, two-dimensional image data of the paper sheet 113 is input at a timing when a photoelectric sensor (not shown) detects the leading end of the paper sheet 113. And

At the same time, based on the two-dimensional image data, the address detection unit 104 detects the position where the address is described (address position information). Then, the position information detecting unit 105 detects a sealable area on the sheet 113 based on the stamp position information and the address position information,
Further, the position where the postmark is actually made is determined.

Next, when the photoelectric sensor 106 detects the leading end of the paper sheet 113, the counter circuit 107 starts counting. The timing of counting in the counting circuit is set in advance, and therefore, the distance by which the sheet 113 is conveyed during one count is determined. The count value of the count circuit is sequentially output to the stamp control circuit 108, and the stamp control circuit 108 detects the position of the conveyed sheet 113 based on the count value.

In the stamp control circuit 108, a sheet 113 detected by the count value output from the count circuit is used.

The operation timing is determined independently, and according to the operation timing,
The respective stamper driving circuits 109 and 110 are operated. Then, the plurality of stampers 111 and 112 stamp on the sheet 113 in accordance with the operation timings of the corresponding stamper drive circuits 109 and 110.

In this embodiment, as shown in FIG. 2, a plurality of rotary hub type stampers 111 and 112 are installed so as to have different heights in the direction perpendicular to the transport direction of the paper sheet 113. However, the sealers 111 and 112 are not limited to this example.

For example, as shown in FIG. 3, a plurality of rotary hub type stampers 111 and 112 can be installed at different positions in the conveying direction of the paper sheet 113. For example, as shown in FIG. 3, when a plurality of stamps and the like are affixed in series to the transport path 101, in a configuration in which only one conventional rotary hub type stamper is installed, the stamper is used. The paper sheet 113 is conveyed during one rotation for imprinting the first stamp or the like, and it is difficult to perform a plurality of postmarks by rotating one stamper twice or more. Was. On the other hand, a plurality of rotary hub type stampers 11
According to a configuration in which the stampers 1 and 112 are installed at different positions with respect to the transport path 101, the stampers 111 and 112 are driven independently, so that stamping can be performed accurately.

Further, as shown in FIG. 4, an ink-jet type stamping device 114 can be used as the stamping means. That is, the paper sheets 11 are vertically moved from above the transport path 101.
A number of nozzles are arranged by the height of 3, and based on the stamping position on the paper sheet 113 detected by the position information detecting unit 105, only the ink droplets at the required positions are skipped from the nozzles and stamped. This ink-jet type stamping device 114
Is used, the stamping can be performed continuously over a wide area without the time loss that the stamping cannot be performed until the disc is rotated once if the stamping is performed once like the rotating hub method.

As shown in FIG. 5, a rotary hub type stamping device 111 and an ink jet type stamping device 114 can be used in combination as the stamping means. Then, as shown in FIG. 6, the station name and date are stamped by a rotary hub type stamping device 111, and a bar mark for the purpose of preventing the reuse of stamps is pressed by an ink jet type stamping device 114. If this is the case, the structure will not be relatively complicated, and the control of the ink jet will be simple.

Next, a second embodiment of the present invention will be described with reference to the drawings.

In the second embodiment, the number of stamping devices to be installed is reduced by half, and only one surface can be stamped by the stamping device. For that purpose, based on the two-dimensional image data of the paper sheet, a surface (hereinafter referred to as a front surface) and a surface (hereinafter referred to as a back surface) of the paper sheet on which stamps and addresses are present are detected, Means for changing the direction of the paper sheet in the transport path is provided so that the surface of the paper sheet always comes to the surface that can be stamped by the stamping device.

FIG. 7 is a block diagram showing the configuration of the second embodiment of the present invention. Since the configuration of the second embodiment is almost the same as that of the first embodiment, the description of the overlapping parts will be omitted. .

As the front / rear surface detecting means, there are publicly known methods such as judging the surface on which the stamps are detected by the charge amount stamp surface detecting unit 103 as the front surface, and judging the surface on which the address position information is detected by the address detecting unit 104 as the front surface. Means may be used. The direction changing unit 202 is configured to execute the stamping unit 1 based on the detection result of the front / back surface detecting unit 201.
The direction of the paper sheet 113 is changed so that the surface of the paper sheet 113 comes to the surface that can be imprinted by 11 and 112. The data conversion unit 203 outputs the stamp position information detected by the fee amount stamp surface detection unit 103 when the direction change unit 202 changes the direction of the paper sheet 113 based on the detection result of the front / back surface detection unit 201. Data conversion is performed between the address information and the address position information detected by the address detection unit 104. The position information detection unit 105 detects a stampable area on the paper sheet 113 while avoiding the address portion, based on the post-conversion stamp position information and the address position information output from the data conversion unit 203. The stamp position on the sheet 113 is determined, and the stamp position information on the stamp position is output to the stamp control unit. Here, the sealers 111 and 112
May be used by any of the stamping means shown in FIGS. 2 to 5, but may be installed so that only one side of the sheet 113 can be stamped.

Next, the operation of the second embodiment will be described with reference to FIGS.

First, when a sheet 113 is conveyed along the conveying path 101, it passes through the two-dimensional image input unit 102.
