Description

  The present invention relates to an imaging apparatus, and more particularly, to a stand-type imaging apparatus used for imaging a form or the like at a window of a financial institution.

  At a counter of a financial institution such as a bank, for example, a stand-type imaging device (OHR: Over Head Reader) is widely used as a device that can read a medium such as a form or a license (for example, Patent Document 1). reference).

  This stand-type imaging device is a non-contact type scanner in which a medium that is an imaging target is placed on a mounting table, and is imaged by a camera from a distant upper part, and an image read by the imaging device is a character recognition Used for applications such as authentication.

  Such a stand-type image pickup device picks up an image by placing a medium such as a document on the mounting table, but in order to prevent the form from sticking to the mounting table when the medium is placed on the mounting table, the surface is A sheet that is not mirror-like is attached to the mounting table. As this sheet, for example, a cloth fabric in which nylon fibers are plain-woven is used. As a result, the contact area with the medium is greatly reduced, so that when preparing for imaging, the medium can be easily moved to a predetermined imaging position while sliding on the sheet.

  Further, since the sheet is stuck on the flat surface of the mounting table, the sheet is used in a state of protruding from the surface of the mounting table by the thickness. For this reason, while the imaging operation is repeated, the end face of the cut portion of the sheet fabric may come into direct contact with or be caught by the clothing, and the end face of the sheet fabric may fray or peel off from the mounting table. is there. On the other hand, a plurality of peeling prevention members are installed on the outer periphery of the sheet to protect the end face of the sheet fabric.

JP 2010-177844 A

  However, the peeling prevention member not only interferes when the form is placed at a predetermined position on the sheet, but also picks up the image at the time of imaging, and therefore prevents peeling from the image data taken by image processing each time the image is taken. The image data of the member for use is deleted. Such image processing has a problem that not only the form image capturing speed is delayed but also the image data of the peeling preventing member may not be completely deleted.

  Even if a peeling prevention member is installed, the sheet fabric may be torn or the exposed end surface of the sheet fabric frayed or peeled off if it is used for a long time or is used frequently. Rehabilitation is required. However, it is necessary to perform this sheet repositioning accurately without any marks on the flat surface of the mounting table. Therefore, it is difficult to align the position when attaching the sheet, and it can only be performed by specialized maintenance personnel. Therefore, there was a problem that the maintenance cost was high.

  It is an object of the present invention to provide an imaging apparatus that prevents fraying of the end face of a sheet fabric due to normal use, eliminates the use of a peeling prevention member, and facilitates sheet repositioning work.

  In order to achieve the above object, an imaging apparatus as shown below is provided. The imaging device includes a mounting table and a sheet. The mounting table has a rectangular outer shape, and has a groove provided on the inner surface along the outer periphery on the surface facing the imaging unit. The sheet has a rectangular placement plane portion on which a medium for imaging is placed and a hanging portion bent in the same direction on four sides of the outer periphery thereof, and the hanging portion is loosely fitted in a groove portion of the placing table. The mounting plane part is affixed to the central plane part of the mounting table surrounded by the groove part.

  According to one aspect, in the state where the hanging portion where the outer periphery of the sheet is bent is inserted into the groove formed in the mounting table, the end surface of the sheet is not exposed by sticking the sheet to the mounting table, and a form or the like There is an advantage that fraying caused by contact can be prevented.

Hereinafter, embodiments will be described in detail with reference to the drawings.
FIG. 1 is a perspective view illustrating a schematic configuration example of an imaging apparatus. The imaging device 10 includes a mounting table 11, a sheet 12, a support unit 13, an imaging unit 14, and a butting member 15.

The mounting table 11 is a table for mounting a medium to be imaged when a medium such as the form 16 is imaged, and has a rectangular outer diameter.
The sheet 12 is a member that is affixed to the surface of the upper surface facing the imaging unit 14 of the mounting table 11 and is formed of a material having appropriate friction and elasticity. Since the sheet 12 is on the upper surface of the mounting table 11, the operator can easily place the form 16 at a predetermined position while sliding the form 16.

The support unit 13 is a rod-like member that is erected on one corner of the mounting table 11, and supports the imaging unit 14 on the top thereof.
The imaging unit 14 is provided on the side facing the mounting table 11, that is, downward, in the vicinity of the tip of the beam portion that extends from the upper end of the support unit 13 to the upper center of the mounting table 11. The imaging unit 14 is, for example, a CCD (Charge-Coupled Device) camera that can acquire a two-dimensional image. In addition, the beam part extended from the support part 13 is provided with the illuminating device for making it illuminate at the time of imaging of a medium as needed.

  The abutting member 15 is a member for abutting the edge of the form 16 to position the form 16 with respect to the imaging unit 14, and in the illustrated example, three pieces are provided along two adjacent sides of the sheet 12. It is installed on the mounting table 11.

  The form 16 is a paper medium in which information is entered. The form 16 is placed on the placement surface of the sheet 12 affixed to the placement table 11. At this time, the operator brings the two sides of the form 16 into contact with the inside of the abutting member 15, so that the form 16 is a reference position scanned by the imaging unit 14 and the scanning direction or the direction orthogonal thereto. It will be positioned accurately in the state directed in the direction to do.

2A and 2B are diagrams showing a specific example of the mounting table, in which FIG. 2A is a perspective view of the mounting table, and FIG. 2B is a partial enlarged view of a part a in FIG. FIG. 3 is a plan view of the mounting table.
As shown in FIG. 3, the mounting table 11 includes an outer peripheral part 110 and a central flat part 111 disposed inside the outer peripheral part 110. In the illustrated example, the outer peripheral portion 110 is formed with a support portion connecting portion 112 for connecting the support portion 13 at the upper left position in the drawing.

  The mounting table 11 also has a sheet insertion part 114 between the outer peripheral part 110 and the central flat part 111 as shown in FIG. The sheet insertion part 114 is a groove provided around the outer periphery of the outer periphery 110 along the outer periphery. Here, the central plane portion 111 of the mounting table 11 is an area where the sheet 12 is affixed, and the sheet insertion portion 114 formed on the outer periphery thereof is a portion into which the outer periphery of the sheet 12 is inserted. Since the central plane portion 111 of the mounting table 11 is an area to which the sheet 12 is affixed, it is formed lower than the upper surface of the outer peripheral portion 110 by the thickness of the sheet 12, and the sheet 12 is affixed to the central plane portion 111. The upper surfaces of the outer peripheral portion 110 and the sheet 12 are flush with each other.

  The mounting table 11 further has an air vent hole 115 and a thrust member insertion hole 116 in the central plane portion 111 of the mounting table 11. A plurality of air vent holes 115 are formed in a discrete manner over the entire surface of the central flat surface portion 111. The air vent hole 115 is a through-hole for drawing air from the air reservoir generated between the sheets 12 to the central plane portion 111 of the mounting table 11 to the lower surface side of the mounting table 11. On the other hand, the thrust member insertion holes 116 are formed at positions close to the four corners of the central flat surface portion 111. In the example shown in the figure, the thrust member insertion hole 116 is formed at one place on the lower right side of the central plane portion 111, but may be provided at a plurality of places. The thrust member insertion hole 116 is for inserting a stick-shaped thrust member from the lower surface side of the mounting table 11 to lift the sheet 12 from the center plane portion 111 when the sheet 12 is peeled from the center plane portion 111. .

  The mounting table 11 is also provided with an abutting member installation portion 117 on two adjacent sides of the central plane portion 111, in the illustrated example, on the upper side and the left side of the central plane portion 111. The abutting member installation portion 117 is an area where the abutting member 15 is installed, and the abutting member 15 is fitted into a fixing hole 118 in which a projection (not shown) is formed in the abutting member installation portion 117. Fixed by.

  The mounting table 11 including the outer peripheral portion 110, the central flat portion 111, the support connecting portion 112, the sheet insertion portion 114, the air vent hole 115, the thrust member insertion hole 116, the butting member installation portion 117 and the fixing hole 118 is as follows. For example, it is integrally formed by aluminum die casting.

4A and 4B are diagrams showing a specific example of the sheet, in which FIG. 4A is a perspective view of the sheet, and FIG. 4B is a partially enlarged view of a portion b of FIG. FIG. 5 is a cross-sectional view showing an example of a laminated structure of sheets.
As shown in FIGS. 4 (A) and 4 (B), the sheet 12 is arranged in the same direction on the central mounting plane portion 120 attached to the central plane portion 111 of the mounting table 11 and on the four sides of the outer periphery thereof. Then, it has the drooping portion 121 bent at a right angle downward. The sheet 12 also has a notch 122 at a position corresponding to the abutting member 15 so that the sheet 12 does not interfere with the abutting member 15 when being stuck to the central flat portion 111 of the mounting table 11.

  The sheet 12 has a laminated structure of a plurality of materials. In the example shown in FIG. 5, the sheet 12 has a nylon plain woven rubberized sheet 123, a double-sided adhesive tape 124, a polyester sheet 125, and a detachable sheet in order from the side facing the imaging unit 14, in other words, the side on which the medium is placed. The laminated structure is a double-sided adhesive tape 126.

  The nylon plain woven rubberized sheet 123 is a sheet in which rubber is bonded to the back surface of a plain woven fabric of nylon fibers, and the nylon fibers are exposed on the surface so that slippage is good when contacting the form 16. ing. This nylon plain woven rubberized sheet 123 is provided with a double-sided pressure-sensitive adhesive tape 124 and a polyester sheet 125 between them in order to improve the adhesiveness to the releasable double-sided pressure-sensitive adhesive tape 126 that is directly bonded to the central plane part 111 of the mounting table 11. Is inserted.

  The releasable double-sided adhesive tape 126 is adhered to the entire back surface of the sheet 12, but when the hanging part 121 is inserted into the sheet insertion part 114, a part other than the sheet insertion part 114 is inserted in the middle. In order to avoid inadvertent adhesion, it is not always necessary to provide the hanging part 121. The illustrated laminated structure is an example of a cloth composite material that forms the sheet 12, and may be formed of a material other than the illustrated material.

  FIG. 6 is a plan view showing a state where the sheet is stuck on the mounting table. 7 is a cross-sectional view taken along the line X-X in FIG. 6, where (A) shows a state before the sheet is attached to the mounting table, and (B) is a partially enlarged view of a portion d in (A). It is sectional drawing. 8 is a cross-sectional view taken along the line XX in FIG. 6, where (A) shows a state where a sheet is attached to the mounting table, and (B) is a partially enlarged cross section of part e in (A). FIG.

  When the sheet 12 is stuck on the central flat surface portion 111 of the mounting table 11, the hanging portion 121 of the sheet 12 is aligned with the sheet insertion portion 114, and the hanging portion 121 is dropped into the sheet insertion portion 114 as it is. The portion 120 is rubbed over the entire surface from above. Here, since the sheet 12 is bent at four angles at right angles and the thin sheet 12 is in a state of being waisted, the hanging part 121 can be easily removed by an external force when inserted into the sheet insertion part 114. Can not be bent. Thereby, the positioning of the hanging part 121 to the sheet insertion part 114 can be performed accurately and easily.

  When the hanging part 121 of the sheet 12 is inserted into the sheet insertion part 114, the hanging part 121 is loosely fitted to the sheet insertion part 114 as shown in FIG. That is, the depth of the sheet insertion part 114 is deeper than the height of the hanging part 121 in the hanging direction, the hanging part 121 is slightly inside the outer peripheral wall 114a, and is sufficiently outside the inner peripheral wall 114b. . For this reason, when the sheet 12 is inserted into the sheet insertion portion 114 with the drooping portion 121 inserted into the sheet insertion portion 114, the outer peripheral surface of the drooping portion 121 extends to the outer peripheral wall 114 a of the sheet insertion portion 114. The sheet 12 can be positioned easily and accurately simply by matching. When the hanging part 121 of the sheet 12 is pushed in this state, the hanging part 121 is inserted into the sheet insertion part 114 while sliding on the outer peripheral wall 114a of the sheet insertion part 114. Further, the sheet 12 can be accurately oriented by matching the notch 122 of the sheet with the abutting member 15 of the mounting table 11.

  The mounting table 11 is formed such that the central flat portion 111 is lower than the surface of the outer peripheral portion 110 outside the sheet insertion portion 114 by the thickness of the sheet 12. Thereby, after sticking the sheet | seat 12 to the center plane part 111 of the mounting base 11, the surface of the sheet | seat 12 and the surface of the outer peripheral part 110 become the same height. For this reason, when the operator moves the form 16, the possibility that the form 16 is caught on the sheet 12 is reduced.

  As described above, the hanging portion 121 that is the end portion of the sheet 12 is loosely fitted to the sheet insertion portion 114, so that the end surface of the sheet 12 faces into the sheet insertion portion 114 and the form 16 or the like is in direct contact. There is nothing. Therefore, the end surface of the sheet 12 can be completely prevented from being frayed. Similarly, the sheet 12 can be prevented from peeling off. Since the peeling of the sheet 12 can be prevented, it is not necessary to install the peeling preventing member on the mounting table 11.

  The sheet 12 is not frayed from the end face even when the imaging device 10 is used for a long time, but the nylon fiber is cut by a hard and pointed object hitting the blade or touching the blade. May become fuzzy. In such a case, the sheet 12 needs to be replaced. Hereinafter, a procedure for peeling the sheet 12 from the mounting table 11 prior to the replacement of the sheet 12 will be described.

  FIG. 9 is a diagram illustrating an example of use of the thrust member insertion hole. When exchanging the sheet 12 affixed to the mounting table 11, it is necessary to first peel off the sheet 12 from the mounting table 11. At this time, the thrust member insertion hole 116 formed in the central flat portion 111 of the mounting table 11 is used. That is, the thrust member is inserted into the thrust member insertion hole 116 from the lower surface side of the mounting table 11. In the example shown in the drawing, a writing instrument 300 that is close to the user such as a pencil is illustrated as a stick-like protruding member. By inserting the writing instrument 300 as a thrust member into the thrust member insertion hole 116, the sheet 12 is pushed up against the surface of the detachable double-sided pressure-sensitive adhesive tape 126 side. Since the thrust member insertion hole 116 is located at a position close to the sheet insertion portion 114, the sheet 12 peels from the sheet insertion portion 114 side. When the sheet 12 is further pushed up by the writing instrument 300 as a thrust member, a part of the hanging part 121 of the sheet 12 comes out from the sheet insertion part 114. Next, the releasable double-sided adhesive tape 126 of the sheet 12 is gradually peeled off from the central flat part 111 of the mounting table 11 by pulling up the hanging part 121 of the sheet 12 that has come out of the sheet insertion part 114. Eventually, the sheet can be completely peeled off from the mounting table.

  As a result, the sheet 12 can be peeled off and the above-mentioned pasting can be performed without relying on specialized maintenance personnel, so that even a general operator can perform the sheet 12 replacement work. Cost can be reduced.

Note that the writing instrument 300 is an example of a thrust member, and any other tool that can penetrate the thrust member insertion hole 116 may be used as the thrust member.
By inserting the thrust member into the thrust member insertion hole 116, the sheet 12 affixed to the mounting table 11 is lifted, so that the operator can easily attach and detach the sheet 12 and the convenience is improved.

In this way, the imaging apparatus 10 can improve the work efficiency of form imaging and reduce maintenance costs.
The image pickup apparatus of the present invention has been described based on the illustrated embodiments. However, the present invention is not limited thereto, and the configuration of each unit can be replaced with any configuration having the same function. Moreover, other arbitrary structures may be added.
