[Structure of Case 100 for Mobile Information Terminal]
3 (a) and 3 (b) are perspective views of the mobile information terminal case 100 according to the present embodiment. FIG. 3A shows a state in which the case 100 for a mobile information terminal is closed, and FIG. 3B shows a state in which the case 100 for a mobile information terminal is open. The case 100 for a mobile information terminal has a rear cover 101 and a front cover 102.

The rear cover 101 is a protective member that detachably supports the mobile information terminal 200 and covers the back surface of the mobile information terminal 200. The front cover 102 is a protective member that covers the front surface of the mobile information terminal 200, which can hold a business card on the mobile information terminal 200 side when the front cover 102 is closed. A support portion 103 that rotatably supports the front cover 102 is provided on the rear cover 101. By rotating the front cover 102 with the support portion 103 as a base point, the front cover 102 can be switched between an open state and a closed state with respect to the rear cover 101.

When the front cover 102 is closed, the front cover 102 is supported substantially parallel to the rear cover 101. When the front cover 102 is open, the front cover 102 is supported at a predetermined angle of less than 180 degrees with respect to the rear cover 101. That is, when the front cover 102 is open, the business card held by the front cover 102 is fixed at a predetermined angle of less than 180 degrees with respect to the mobile information terminal 200.

The front cover 102 functions as a storage unit that can store a plurality of business cards in a stacked manner. The front cover 102 is provided with a through hole 104 that communicates the inside and the outside of the case 100 for a mobile information terminal.

A first protruding portion 105 and a second protruding portion 106 are provided on the inner wall of the front cover 102. The first projecting portion 105 is a member provided so as to project perpendicularly to the side wall of the front cover 102 (that is, the wall extending along the end portion of the business card). The first protruding portion 105 covers a part of the surface of the business card so as not to hide the characters written on the business card when the business card is imaged. The second projecting portion 106 is a member provided so as to project perpendicularly to the top plate of the front cover 102 (that is, a wall extending along the surface of the business card). The second protrusion 106 covers a part of the end of the business card.

Further, the front cover 102 is provided with an imaging assisting unit 150 for assisting the imaging of the business card held in the front cover 102. The image pickup assisting unit 150 is composed of an external camera that inputs the captured image of the business card held in the front cover 102 to the mobile information terminal 200 and a business card held in the front cover 102 in the camera 230 included in the mobile information terminal 200. Includes at least one with an optical member (eg, a mirror or lens) that guides the light. The detailed configuration of the image pickup assisting unit 150 will be described below with reference to FIGS. 4 and 5.

4, 5 (a) and 5 (b) are cross-sectional views of the mobile information terminal case 100 according to the present embodiment in a state where the business card C is housed. 4, 5 (a) and 5 (b) show the cross section of the line AA in FIG. 3 (b). When the front cover 102 is closed and the front cover 102 is parallel to the rear cover 101 at 0 degrees, the front cover 102 in the open state is greater than 0 degrees and less than 180 degrees with respect to the rear cover 101. It is supported at a predetermined angle.

If the business card C housed in the front cover 102 is supported at a steep angle with respect to the rear cover 101, the distortion of the captured image of the business card C becomes large, and the character information may not be correctly acquired from the captured image. Therefore, in order to improve the accuracy of acquiring character information from the image of the business card C, the front cover 102 is preferably supported at a predetermined angle of 90 degrees or more and 150 degrees or less with respect to the rear cover 101.

The recipient causes the camera 230 of the mobile information terminal 200 or the external camera 151 described later to take an image by performing a predetermined operation on the mobile information terminal 200. The camera 230 or the external camera 151 captures the innermost business card C1 (that is, the side closer to the camera 230 or the external camera 151) among the business cards C housed in the front cover 102, and captures the captured content as an captured image. get. Then, the mobile information terminal 200 displays information related to the business card C1 based on the captured image.

With such a configuration, the mobile information terminal 200 can read the business card C housed in the front cover 102, so that the recipient receives the business card C from the provider and puts it in the case 100 for the mobile information terminal. Information related to business card C can be acquired as a part. Therefore, it is not necessary to bother to put in and take out the business card C for reading.

Of the business cards C housed in the front cover 102, the outermost business card C2 (that is, the side closer to the front cover 102) faces the through hole 104 on the front cover 102. The recipient can take out the business card C2 from the front cover 102 by touching and sliding the business card C2 housed in the front cover 102 through the through hole 104.

The recipient stores his / her business card C in the front cover 102. When exchanging business cards, the recipient takes out the outermost business card C2 as his own business card C and hands it to the provider, and puts the business card received from the provider inside the front cover 102. As a result, the innermost business card C1 becomes the provider's business card C, and imaging by the camera 230 or the external camera 151 becomes possible.

At this time, one recipient's business card C is taken out from the front cover 102, and at the same time, one provider's business card C is added to the front cover 102. That is, the front cover 102 is configured to be shared by the recipient's business card C and the provider's business card C. As a result, the distance between the camera 230 or the external camera 151 and the innermost business card C1 (that is, the provider's business card C) is kept constant, so that changes in the conditions under which the captured image is captured are suppressed and imaging is performed. It is possible to improve the accuracy of acquiring character information from an image.

Since the first protruding portion 105 projects so as to cover a part of the surface of the business card C, when the recipient touches the business card C through the through hole 104, the business card C refers to the top plate of the front cover 102. It is possible to support the business card C so that it is not pushed out in the vertical direction so that the business card C can be stably taken in and out. Since the second protruding portion 106 projects so as to cover a part of the end portion of the business card C, it is possible to prevent the business card C from popping out from the front cover 102 when opening and closing the case 100 for the mobile information terminal.

The first protruding portion 105 may be a transparent plate made of glass, acrylic or the like and covering the entire business card C. In this case, the transparent plate as the first protrusion 105 is provided substantially parallel to the top plate of the front cover 102. The business card C is housed in the space between the top plate of the front cover 102 and the first protrusion 105. The camera 230 or the external camera 151 captures the business card C housed in the front cover 102 via the first protrusion 105. Even in such a configuration, the first protrusion 105 prevents the business card C from being pushed out in the direction perpendicular to the top plate of the front cover 102 when the recipient touches the business card C through the through hole 104. It can be supported and the business card C can be stably put in and taken out.

FIG. 4 shows a case 100 for a mobile information terminal having an external camera 151 as an image pickup assisting unit 150. The external camera 151 is an imaging unit that captures a predetermined imaging range. The external camera 151 is connected to the mobile information terminal 200 attached to the case 100 for the mobile information terminal by wire or wirelessly.

The external camera 151 is provided in the rear cover 101 at a position and orientation in which the characters written on the business card C held on the front cover 102 with the front cover 102 open can be imaged. The mobile information terminal 200 inputs an imaging instruction to the external camera 151 when a predetermined operation is performed on the operation unit 250. The external camera 151 images the business card C according to the imaging instruction received from the mobile information terminal 200, and inputs the captured image of the business card C to the mobile information terminal 200.

In the mobile information terminal 200, the camera 230 is generally provided so as to image the front surface of the mobile information terminal 200. Therefore, as shown in FIG. 4, when the front cover 102 is open, it is difficult for the mobile information terminal 200 to image the business card C held by the front cover 102. On the other hand, the mobile information terminal 200 captures the business card C by using the external camera 151 provided in the case 100 for the mobile information terminal, so that the business card C remains attached to the case 100 for the mobile information terminal. Captured images can be acquired.

FIG. 5A shows a case 100 for a mobile information terminal having a mirror 152 as an image pickup assisting unit 150. The mirror 152 is an optical member that guides the light L reflected on the business card C held by the front cover 102 to the camera 230 of the personal digital assistant 200 with the front cover 102 open. For example, the mirror 152 is a plane mirror provided in the rear cover 101 at a position and orientation for reflecting light L toward the camera 230. As a result, the personal digital assistant 200 can take an image of the business card C reflected on the mirror 152 by using the camera 230 even when the business card C is not in front of the camera 230. The mirror 152 may be stored in a position and orientation different from the state in which the front cover 102 is opened when the front cover 102 is closed.

FIG. 5B shows a case 100 for a mobile information terminal having a lens 153 as an image pickup assisting unit 150. The lens 153 is an optical member that guides the light L reflected on the business card C held by the front cover 102 to the camera 230 included in the personal digital assistant 200 with the front cover 102 open. For example, the lens 153 is a prism lens provided in the rear cover 101 at a position where the light L is refracted toward the camera 230. As a result, the portable information terminal 200 can take an image of the business card C through the lens 153 using the camera 230 even when the business card C is not in front of the camera 230. The lens 153 may be housed in a position and orientation different from the state in which the front cover 102 is opened when the front cover 102 is closed.

In the mobile information terminal 200, the camera 230 is generally provided so as to image the front surface of the mobile information terminal 200. Therefore, as shown in FIGS. 5A and 5B, when the front cover 102 is open, it is difficult for the personal digital assistant 200 to image the business card C held by the front cover 102. On the other hand, the mobile information terminal 200 uses the mirror 152 or the lens 153, which is an image pickup assisting unit 150 provided in the case 100 for the mobile information terminal, to image the business card C, thereby forming the case 100 for the mobile information terminal. The captured image of the business card C can be acquired while it is attached.

[Modification example]
In the examples of FIGS. 3 to 5, the mobile information terminal 200 captures the business card C by using the camera 230 (front camera) that images the front side, but the mobile information terminal 200 is the case 100 for the mobile information terminal. The business card C may be imaged by using a camera 230 (rear camera) that images the back side.

FIG. 6 is a cross-sectional view of the mobile information terminal case 100 according to the modified example of the present embodiment in a state where the business card C is housed. FIG. 6 shows the configuration of a case 100 for a mobile information terminal when the mobile information terminal 200 images a business card C using a camera 230 that images the back side. In this case, the front cover 102 can hold the business card on the side opposite to the mobile information terminal 200 when the front cover 102 is closed.

When the front cover 102 is closed and the front cover 102 is parallel to the rear cover 101 at 0 degrees, the front cover 102 in the open state is greater than 180 degrees and less than 360 degrees with respect to the rear cover 101. It is supported at a predetermined angle. In order to improve the accuracy of acquiring character information from the image of the business card C, the front cover 102 is preferably supported at a predetermined angle of 210 degrees or more and 270 degrees or less with respect to the rear cover 101. That is, when the front cover 102 is open, the business card C held by the front cover 102 is fixed at a position where it can be imaged by the camera 230 of the portable information terminal 200.

In FIG. 6, the lens 153 is provided at a position of covering the camera 230 on the rear cover 101. The lens 153 refracts the light L reflected on the business card C held by the front cover 102 toward the camera 230. In this modification, instead of the lens 153, an external camera 151 or a mirror 152 may be provided on the rear cover 101 as an image pickup assisting unit 150.

In this way, the case 100 for the mobile information terminal holds the business card C on the side opposite to the mobile information terminal 200 on the front cover 102, so that the captured image of the business card C is acquired by using the rear camera of the mobile information terminal 200. Can be made possible.

[Explanation of business card management method]
Hereinafter, the business card management method executed by the business card management system S according to the present embodiment will be described in detail. First, the recipient accommodates the business card received from the provider in the front cover 102 of the case 100 for the mobile information terminal. The recipient performs a predetermined operation (for example, pressing a button) on the operation unit 250 of the mobile information terminal 200, so that the camera 230 or the external camera 151 can take an image of the business card housed in the front cover 102. Let me do it.

In the mobile information terminal 200, the image acquisition unit 211 acquires the captured image captured by the camera 230 or the external camera 151. The transmission unit 212 transmits the captured image acquired by the image acquisition unit 211 to the business card management device 300.

In the business card management device 300, the image receiving unit 311 receives the captured image transmitted by the mobile information terminal 200. The character information acquisition unit 312 performs known character recognition processing such as OCR (optical character recognition) on the captured image received by the image receiving unit 311 to obtain character information indicating the characters written on the business card. It is acquired and stored in the storage unit 320.

Character information includes personal information such as name, affiliation (that is, corporate name, organization name, school name, etc.), telephone number, and e-mail address written on a business card, for example. In addition to personal information, if information such as career information and identification information on SNS (Social Networking Service) is written on the business card, the character information acquisition unit 312 acquires such information as character information. May be good.

The acquisition of character information from the captured image of the business card may be performed by the control unit 210 of the mobile information terminal 200. In this case, the character information acquisition unit 312 acquires the character information by receiving the character information from the mobile information terminal 200.

The additional information acquisition unit 313 acquires additional information related to the character information acquired by the character information acquisition unit 312 when the character information acquisition unit 312 can acquire the character information. The additional information includes historical information related to the character information acquired this time by the character information acquisition unit 312, which indicates the character information acquired in the past from the captured image of the business card of a person different from the business card provider, and the business card provider. Includes at least one of the common information indicating the commonality between the mobile information terminal 200 and the user (that is, the recipient) of the mobile information terminal 200.

As the history information, the additional information acquisition unit 313 has acquired the character information acquisition unit 312 this time among the character information acquired from the business card of a person different from the provider of the current business card stored in the storage unit 320 in the past. Acquires past character information including at least a part of character information (for example, affiliation or domain name of an email address).
