Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a seal verification device for verifying whether a seal used by a customer at the time of a transaction at a financial institution such as a bank is the same as a registered seal. .
[0002]
[Prior art]
The seal inquiry system currently used by financial institutions obtains images of customer seals with an image scanner, etc. at the time of opening an account, etc., which is filed as registered seal data and managed by the host computer at the financial institution's center. However, an account number etc. is added to each registered seal data as a code when making a file, and when a transaction seal verification is necessary, a staff member of a financial institution uses the input means such as a keyboard to By inputting the code, the target registered seal data is read and the image of the actual seal is displayed on the screen of the display unit of the seal verification device. This seal image and the form presented by the customer (for example, payment bill) Compared with the imprint of the check target stamped on the banknote or passbook).
[0003]
Also, add image acquisition means such as a video camera or image scanner to the seal verification device, acquire the imprint of the verification target stamped on the form presented by the customer at the transaction, and register the image Devices that are displayed side by side on the screen of a display device together with an image based on seal data, or are displayed in a superimposed manner have also been put into practical use.
[0004]
[Problems to be solved by the invention]
However, the conventional techniques described above have the following problems.
First, in the case of a device that displays only the image based on the registered seal data on the display unit, if the stamp content of the seal is complicated, the image based on the registered seal data displayed on the display unit and the seal on the form are visually checked. Depending on the display position on the display unit, the stamp position on the form, etc., it becomes extremely difficult to distinguish the delicate marking contents.
[0005]
In addition, when an image acquisition unit such as a video camera or an image scanner is added to configure a seal stamp verification apparatus, it is possible to easily perform verification of seal stamps with complicated stamp contents, but the apparatus is expensive and financial institutions It is not suitable for installation in a narrow space such as a counter on the first line.
Accordingly, the present invention realizes a stamp verification apparatus that can easily perform verification of a stamp with complicated stamp contents, is inexpensive, can be used in a small installation space, and can be easily manufactured. It is intended.

The optical system unit 2 includes a horizontal form placing table 3 on which a form is placed, a mounting portion 4 provided so as to stand vertically on the rear end side of the form placing table 3, and A half mirror 5 provided on the front side of the mounting portion 4 is provided, and this half mirror 5 is fixedly supported via a support member so as to form an angle of 45 degrees with respect to the form mounting table 3 and the mounting portion 4. ing.
[0009]
FIG. 2 is a perspective view of the display unit 1. As shown in FIG. 2, the display unit 1 is provided with two positioning grooves 6a and 6b having a V-shaped cross section on the upper surface thereof. Two positioning protrusions having a V-shaped cross section corresponding to 6b are provided on the bottom surface of the mounting portion 4 of the optical system unit 2 shown in FIG. The unit 1 is turned upside down and placed in the mounting portion 4 so that the screen faces the half mirror 5, and positioning is performed by fitting the positioning grooves 6 a and 6 b of the display unit 1 to the positioning protrusions of the mounting portion 4. By that, it is to be worn.
[0010]
FIG. 3 is a diagram for explaining detection means (detection circuit) for detecting the attachment / detachment of the display unit 1. In the figure, reference numerals 7a and 7b denote positioning protrusions of the mounting portion 4, and electrodes are provided on the surfaces of the positioning grooves 6a and 6b of the display unit 1. 8a and 8b are provided, and electrodes 9a and 9b are provided on the surfaces of the positioning projections 7a and 7b.
Here, the electrodes 8a and 8b are each pulled up by the reference potential VEE, and the electrodes 9a and 9b are respectively set to the GND level.
[0011]
Therefore, when the display unit 1 is in a single state, the electrodes 8a and 8b are in an open state, so that a state pulled up with the reference potential VEE, that is, a high level signal appears on the signal lines ST1 and ST2, and the display unit When 1 is mounted on the mounting portion 4 of the optical system unit 2, the positioning grooves 6a and 6b are fitted into the positioning protrusions 7a and 7b, respectively, so that when the electrodes 8a and 8b come into contact with the electrodes 9a and 9b, a low level signal is generated. Appearing on the signal lines ST1 and ST2, the attachment / detachment of the display unit 1 is thereby detected.
[0012]
FIG. 4 is a block diagram showing a control system in the display unit 1.
In the figure, 10 is an image memory for storing registered seal data transferred from a file (not shown), 11 is a display unit for displaying an actual-size seal image based on the registered seal data, 12 is a display unit controller, and 13 is a display unit 1. A control unit (CPU) that controls the whole, the control unit 13 reads the registered seal data stored in the image memory 10, writes the read registered seal data to the display unit controller 12, and displays the seal image on the display unit 11. It is to be controlled to project.
[0013]
FIG. 5 is an explanatory diagram showing a method for reading registered seal stamp data from the image memory 10.
In the image memory 10, registered seal data is developed as X0 to Xn in the main scanning direction and Y0 to Ym in the sub-scanning direction as shown in the figure, and the control unit 13 selects the image according to the usage mode of the display unit 1. The registered seal stamp data is read from the memory 10 in the X0 → Xn (normal mode) direction in the main scanning direction, or is read in the Xn → X0 (reverse mode) direction.
[0014]
FIGS. 6A and 6B are diagrams each showing a display form of the read registration seal data.
When the control unit 13 reads the registered seal data from the image memory 10 in the X0 → Xn direction in the main scanning direction, the seal image based on the registered seal data is displayed in a normal state as shown in FIG. .
[0015]
On the other hand, when the control unit 13 reads the registered seal data from the image memory 10 in the Xn → X0 direction in the main scanning direction, the seal image is displayed in a state where the left and right sides are reversed as shown in FIG. .
Next, the operation of the above configuration will be described.
First, the present stamp verification apparatus has two usage methods: a case where the display unit 1 is used alone and a case where the display unit 1 is used in combination with the optical system unit 2.
[0016]
The display unit 1 is used alone, for example, when a stamp with simple stamp contents is collated, and the display unit 1 is used in a normal state as shown in FIG.
In this state, when a staff member who operates the seal verification device looks at the form submitted by the customer and enters a code such as an account number, the entered code is transferred to the host computer at the center of the financial institution by the control unit 13, and the host The corresponding registered seal data is read from the file by the computer and sent to the control unit 13.
[0017]
The registered seal stamp data is temporarily stored in the image memory 10 and the controller 13 recognizes the mode, which will be described below, between the normal mode and the reverse mode.
That is, when the display unit 1 is used alone, the electrodes 8a and 8b provided in the positioning grooves 6a and 6b of the display unit 1 are open as described with reference to FIG. 3, and are pulled with the reference potential VEE. Since the high level signal appears on the signal lines ST1 and ST2, the control unit 13 determines that the display unit 1 is not mounted on the mounting unit 4 of the optical system unit 2 based on the high level signal, and the normal mode. Recognize that
[0018]
As a result, the control unit 13 reads the registered seal data from the image memory 10 in the direction of X0 → Xn in the main scanning direction and in the direction of Y0 → Ym in the sub-scanning direction as shown in FIG. 6 is displayed on the display unit 11 as a normal image as shown in FIG. 6A, the clerk compares the displayed image with the imprint of the check target stamped on the form presented by the customer, and verifies the seal. I do.
[0019]
On the other hand, when the display unit 1 is used in combination with the optical system unit 2, for example, a seal with a complicated stamp content is collated. As described above, the display unit 1 is turned upside down and placed on the form placement table 3. The display unit 1 is placed in a vertical position so as to form a right angle, and the positioning grooves 6a and 6b of the display unit 1 are fitted into the positioning protrusions 7a and 7b of the mounting unit 4 for positioning.
[0020]
As a result, the display unit 1 is mounted in the mounting unit 4. In this state, the attendant looks at the form submitted by the customer and inputs a code such as an account number using a keyboard (not shown). The data is transferred to the host computer at the center of the financial institution by the control unit 13, and the corresponding registered seal data is read from the file by the host computer and sent to the control unit 13, and then stored in the image memory 10.
[0021]
Here, the display mode is recognized by the control unit 13.
In this case, the positioning grooves 6a and 6b are fitted into the positioning protrusions 7a and 7b, respectively, so that the electrodes 8a and 8b and the electrodes 9a and 9b come into contact with each other, and a low level signal appears on the signal lines ST1 and ST2. Based on the level signal, the control unit 13 determines that the display unit 1 is mounted on the mounting unit 4 of the optical system unit 2, and recognizes that the display unit 1 is in the inversion mode.
[0022]
As a result, the control unit 13 reads the registered seal data from the image memory 10 in the direction of Xn → X0 in the main scanning direction and in the direction of Y0 → Ym in the sub-scanning direction as shown in FIG. 6 is displayed as an image with the left and right sides reversed as shown in FIG.
Since the display unit 1 is mounted on the mounting unit 4 with the display unit 1 turned upside down as described above, the image of the display unit 1 is displayed as an upside down image. Since the left and right are further reversed by being reflected on the half mirror 5 of the optical system unit 2, when the half mirror 5 is viewed from above toward the front of the optical system unit 2, the image can be seen in a normal shape.
[0023]
FIG. 7 is an explanatory diagram showing the re-inversion of the image at this time. The image displayed on the display unit 1 is an upside down image as shown in FIG. When viewed from above, the left and right sides are further reversed, and when viewed from above, the image becomes normal as shown in (b).
14 is a form presented by the customer, and this form 14 is placed on the form placement table 3 of the optical system unit 2 by an attendant.
[0024]
The imprint of the check mark stamped on this form is normal as shown in (c), and even when looking into the half mirror 5 from above, it looks in the normal form as shown in (d) through the half mirror 5. Therefore, the seal image based on the registered seal data projected on the half mirror 5 and the seal stamp are superimposed on the form 14, and the attendant collates the seal.
[0025]
FIG. 8 is an explanatory diagram of detection means (detection circuit) for detecting attachment / detachment of the display unit 1. In this example, the positioning grooves 6a and 6b and the positioning projections 7a and 7b have electrodes 8a and 8b as shown in FIG. The electrodes 9a and 9b are not provided, and switches 15a and 15b are provided in the positioning grooves 6a and 6b instead.
Here, the electrodes 8a and 8b are each pulled up by the reference potential VEE, and the electrodes 9a and 9b are respectively set to the GND level.
[0026]
In this case, when the display unit 1 is in a single state, the switches 15a and 15b are not pressed and are in an open state, so that a state pulled up by the reference potential VEE, that is, a high level signal appears on the signal lines ST1 and ST2. When the display unit 1 is mounted on the mounting portion 4 of the optical system unit 2 and the positioning grooves 6a and 6b are fitted to the positioning projections 7a and 7b, the switches 15a and 15b are pressed by the positioning projections 7a and 7b. Therefore, a low level signal appears on the signal lines ST1 and ST2.
[0027]
Therefore, the control unit 13 can recognize whether the display unit 1 is attached or detached based on these signals, and can recognize the normal mode or the reverse mode.
According to the first embodiment described above, for example, when collating a stamp with simple stamp contents, the collation can be performed by using the display unit alone, and a stamp with complicated stamp contents can be collated. In this case, by attaching the display unit to the mounting part of the optical system unit, it is possible to easily check the seal of complicated stamp contents using the half mirror of the optical system unit. Since it is easy, it is excellent in handleability.
[0028]
In addition, the optical system unit having a half mirror is less expensive than combining image acquisition means such as a video camera or an image scanner, and the optical system unit can be configured in a small size corresponding to the display unit, so it does not take up space. For this reason, it can sufficiently cope with a narrow installation space such as a first-line counter of a financial institution.
[0029]
Furthermore, when the display unit is mounted on the mounting part of the optical system unit, a means for detecting it is provided, and the normal display and the reverse display are automatically switched based on the output of the detection means. The clerk does not need to specify the display mode and is excellent for operation students.
Next, a second embodiment will be described.
[0030]
FIG. 9 is a schematic side view showing the second embodiment, FIG. 10 is a perspective view of the display unit 1 in the second embodiment, and FIG. 11 is a plan view of the form mounting table 3 in the second embodiment. It is.
The basic configurations of the display unit 1 and the optical system unit 2 in the second embodiment are the same as those in the first embodiment, but differ in the following points.
[0031]
First, a maintenance mode is added as a display mode of the display unit 1 in addition to the normal mode and the inversion mode, and this maintenance mode has a function of displaying, for example, a well-shaped reference pattern 16 as shown in FIG.
That is, the data of the reference pattern 16 is stored in the image memory 10 shown in FIG. 4, and the control unit 13 reads the data from the image memory 10 and displays it on the display unit 11 in the maintenance mode. .
[0032]
Also, as shown in FIG. 11, a reference pattern 17 having the same shape is provided in advance on the upper surface of the document mounting table 3 of the optical unit 2 by stamping or printing. This reference pattern 17 is printed on a sticker and maintained. It is also possible to affix to the form mounting table 3 in the mode.
Further, the half mirror 5 of the optical unit 2 is provided so as to be movable in the vertical direction with respect to the mounting portion 4 together with the support member, and a moving mechanism for moving the half mirror 5 and the support member integrally up and down. 18 is provided.
[0033]
For example, the moving mechanism 18 is provided with a pinion (gear) integrated with the operation knob on the front end side of the mounting portion 4, a rack that meshes with the pinion is fixed to the support member of the half mirror 5, and the operation knob is manually operated. Then, by rotating the pinion, the half mirror 5 can be moved up and down integrally with the supporting member via the rack. In addition, a toothed pulley and a toothed belt are combined. Any thing can be adopted.
[0034]
Since the second embodiment having such a configuration is the same as the first embodiment except that the display mode is designated as the normal mode using the keyboard when the seal unit is collated with the display unit 1 alone, the description thereof will be given. Is omitted.
When the display unit 1 is used in combination with the optical system unit 2, the display unit 1 is mounted on the mounting portion of the support member 23 in the optical system unit 21, and the display unit 1 is set to the adjustment mode using a keyboard (not shown). A reference pattern 16 is displayed on the unit 1.
[0035]
When the half mirror 5 is looked into from the upper side toward the front of the optical system unit 2 in this state, the reference pattern 16 displayed on the display unit 1 is displayed on the half mirror 5 so that it can be visually checked. The reference pattern 17 is visible through the half mirror 5.
FIG. 12 shows the reference pattern 16 and the reference pattern 17 at this time.
[0036]
Therefore, in this state, if the distance L1 from the display unit 1 to the half mirror 5 and the distance L2 from the half mirror 5 to the form mounting table 3 are the same, the reference pattern 16 of the display unit 1 displayed on the half mirror 5 is displayed. The reference pattern 17 on the form placement table 3 that can be seen through the half mirror 5 has almost the same size, and the reference patterns 16 and 17 overlap and match.
[0037]
However, if the distances L1 and L2 are different, the sizes of the reference pattern 16 and the reference pattern 17 will also appear different. In this case, the operation knob of the moving mechanism 18 is manually operated to rotate the pinion. The half mirror 5 is moved up and down in the direction of the arrow A shown in FIG. 12 together with the support member by the action of the pinion and the rack so as to adjust the distances L1 and L2 to be the same.
[0038]
The adjustment of the stamp after the adjustment is performed in the same manner as in the first embodiment. In this case, the image of the seal stamp based on the registered seal stamp data and the shadow of the checked stamp on the form are the same size, so that the clerk has high accuracy. Matching can be performed easily.
According to the second embodiment described above, the same effects as those of the first embodiment can be obtained, the display unit has a function of displaying a reference pattern, and the same reference pattern is provided on the form placement table. Since the moving mechanism that moves the half mirror of the optical system unit up and down integrally with the support member is provided, the distance from the display unit to the half mirror and the distance from the half mirror to the document mounting table can be easily made equal. This makes it possible to make the image of the registered seal data and the shadow of the check mark on the form the same size. Since the distance from the half mirror and the distance from the half mirror to the document mounting table can be easily adjusted, high assembly accuracy is not required. Production to ease it is possible.
[0039]
Next, a third embodiment will be described.
FIG. 13 is a schematic side view showing the third embodiment. This third embodiment is obtained by adding a light source 19 to the configuration of the first embodiment.
The light source 19 is for illuminating the form 14 placed on the form mounting table 3, and a fluorescent lamp or the like is used to support the half mirror 5 so as to be positioned on the lower surface side of the half mirror 5. It is attached to the support member.
[0040]
In the third embodiment having such a configuration, the seal is collated in the same manner as in the first embodiment. However, the display unit 1 is mounted on the mounting portion 3 of the optical system unit 2 so that the seal is printed. When collating, the attendant looks into the half mirror 5 so as to cover the upper part of the optical system unit 2, so that the light from the room light 20 from the overhead direction is blocked and the form placed on the form placement table 3. Insufficient light quantity for 14 may make it difficult to see the imprint of the checked mark stamped on the form 14.
[0041]
Therefore, in the third embodiment, since the form 14 on the form placement table 3 can be sufficiently illuminated by turning on the light source 19, it is possible to eliminate the difficulty of seeing the imprint of the check mark.
According to the third embodiment described above, since the optical system unit is provided with a light source that illuminates the form 14 placed on the form placement table 3, it is stamped on the form 14 at the time of seal verification. It is possible to perform collation in a good state without making it difficult to see the imprint of the collation mark.
[0042]
Next, a fourth embodiment will be described.
FIG. 14 is a schematic side view showing the fourth embodiment.
In the figure, reference numeral 1 denotes a display unit, which is basically the same as that of the first embodiment, but does not have a positioning groove on the upper surface, and detects attachment / detachment to an optical system unit described later. It does not have a circuit or a switch.
[0043]
Therefore, switching between the normal mode and the reverse mode of the display unit 1 is designated by a staff using a keyboard (not shown).
Reference numeral 21 denotes an optical system unit. The optical system unit 21 includes a form holding part 22 for inserting and holding the form 14, a support member 23 having the lower part as a mounting part for the display unit 1 and fixedly supporting the half mirror 5, and an optical system unit. A stand portion 24 is provided on the lower surface of the support member 23 so as to keep 21 at a constant angle.
[0044]
Here, it is assumed that the display unit 1 is mounted on the mounting unit with the upper surface facing forward, and at that time the display unit 1 and the form holding unit 22 form an angle of about 90 degrees, and the half mirror 5 Are fixedly supported so as to form an angle of 45 degrees with respect to the display unit 1 and the form holder 22 mounted on the mounting portion of the support member 23.
[0045]
In the third embodiment having such a configuration, when collating a seal with the display unit 1 alone, it is performed in the same manner as in the first embodiment except that the display mode is designated as the normal mode using the keyboard board.
When the display unit 1 is used in combination with the optical system unit 21, the display unit 1 is mounted on the mounting portion of the support member 23 in the optical system unit 21, and the display mode is designated as the reverse mode using the keyboard.
[0046]
As a result, the seal image based on the registered seal data is displayed on the display unit 1 in a horizontally reversed form, so that the clerk inserts the form 14 presented by the customer into the form holding unit 22 and holds it. The half mirror 5 is looked at from diagonally upward so as to face the front of the form, and the seal image is superposed on the form 14 with the seal image based on the registered seal data projected on the half mirror 5 and the seal is collated.
[0047]
At this time, the light of the room light from the overhead direction is not obstructed, and the form 14 is illuminated by the light of the room light, so that the imprint of the check mark is not difficult to see. According to the fourth embodiment described above, the same effects as those of the first embodiment can be obtained, and when the display unit is used in combination with the optical system unit, the seal is the half mirror 5 from above. There is no need to look into the form, and the form is illuminated by the light of the room light, so that it is possible to perform collation in a good state and no light source or power source is required compared to the third embodiment. The configuration is simplified and the increase in cost can be prevented.
[0048]
【The invention's effect】
As described above, the present invention can perform verification using a display unit alone when verifying a stamp with a simple stamp content, and also display a seal when verifying a stamp with complicated stamp content. By attaching the unit to the mounting part of the optical system unit, it is possible to easily perform verification of seals with complicated stamp contents using the half mirror of the optical system unit, and also to attach the display unit. Is easy, so that it is possible to obtain an excellent handleability.
[0049]
In addition, the optical system unit having a half mirror is less expensive than combining image acquisition means such as a video camera or an image scanner, and the optical system unit can be configured in a small size corresponding to the display unit, so it does not take up space. As a result, it is possible to sufficiently cope with a narrow installation space such as a first-line counter of a financial institution.
[0050]
Furthermore, when the display unit is mounted on the mounting part of the optical system unit, a means for detecting it is provided, and the normal display and the reverse display are automatically switched based on the output of the detection means. There is no need for the attendant to specify the display mode, and it is possible to obtain an effect that the operation staff is excellent.
