Description

The present invention relates to an electronic stamp device.

In recent years, electronic stamp devices have become increasingly popular as a means of presenting coupons and electronic tickets, for example. When an electronic stamp is stamped on the screen of a mobile communication terminal or the like, the electronic stamp device displays an image or other indication on the screen that the stamp has been stamped. Electronic stamp devices are not only used for presenting coupons, but are also expected to be used in a wide range of fields, such as toys, in the future.

As described in Patent Document 1 below, an electronic stamp has multiple protrusions made of a conductive material, which come into contact with the screen when stamped. The screen on which the electronic stamp is stamped is, for example, a capacitive touch panel. With this configuration, it is possible to detect stamping on the screen and display an image, etc., on the screen.

Japanese Patent Application Laid-Open No. 2017-182381

Depending on the application of the electronic stamp device, it may be possible to prepare multiple types of electronic stamps in advance and display different images on the screen when stamping each stamp. However, if multiple electronic stamps are prepared, component costs will increase and storing and managing the electronic stamps will become more complicated.

For example, it would be possible to provide a selector switch on the electronic stamp or display device, and change the image displayed when stamping depending on the state of that switch. However, in this case, the structure of the electronic stamp, etc. would become too complicated, and the cost of parts would increase.

The objective of the present invention is to provide an electronic stamp device that has a simple configuration yet allows users to select from multiple types of images to display when stamping.

The electronic stamp device according to the present invention comprises an electronic stamp, a display unit where the stamp is applied and displays an image when the stamp is applied, and a control unit that controls the operation of the display unit. The control unit has a determination unit that determines the orientation of the applied electronic stamp, a selection unit that selects an image to be displayed on the display unit from among multiple candidates according to the orientation determined by the determination unit, and a processing unit that performs processing to display the image selected by the selection unit on the display unit.

If the electronic stamp device is configured in this way, the user can switch the image displayed when stamping simply by changing the orientation of the electronic stamp. Since there is no need to provide a mechanism such as a selector switch to allow the user to select an image from multiple candidates, the structure of the electronic stamp device does not become complicated.

This invention provides an electronic stamp device that has a simple configuration yet allows users to select from multiple types of images to display when stamping.

This embodiment will now be described with reference to the accompanying drawings. To facilitate understanding, identical components in each drawing will be designated by the same reference numerals whenever possible, and duplicate explanations will be omitted.

The electronic stamp device 10 according to this embodiment is a toy for children, and includes an electronic stamp 20 and a display device 40. The configuration and functions of the electronic stamp device 10 described below can also be used for purposes other than toys. One example of a use of such an electronic stamp device is to stamp "used" on a coupon on a mobile device presented by a customer in a store, etc.

The electronic stamp 20 is used as a so-called "stamp" and is held by the user when stamping, with part of it pressed against (i.e., stamped on) the display unit 410, which will be described later. The specific configuration of the electronic stamp 20 will be described later.

The display device 40 is a thin computer device also known as a "tablet terminal." A display unit 410 is provided on the top surface of the display device 40. The display unit 410 is a capacitive touch panel screen, and is a rectangular screen as shown in FIG. 1. When a conductor with a large capacitance, such as a human body, touches the display unit 410, the display device 40 detects this and can determine the position where the conductor touched, or display a specific image at that position on the display unit 410. The display unit 410 is the part where an imprint is made by the electronic stamp 20, and where an image is displayed when the imprint is made.

A control unit 450 (not shown in Figure 1, see Figure 5) is provided inside the display device 40 to control the overall operation of the device, including the display unit 410. When a user holds the electronic stamp 20 and presses its bottom surface against the display unit 410, the control unit 450 detects this and displays the image 50 in the same position on the display unit 410. The configuration of the control unit 450 and the specific content of the processing performed by the control unit 450 will be described later.

The specific configuration of the electronic stamp 20 will be described with reference to Figure 2 and other figures. Figure 2 is a perspective view of the electronic stamp 20 viewed from above. Figure 3 is a view of the electronic stamp 20 viewed from the bottom. Figure 4 is a cross-sectional view showing the internal configuration of the electronic stamp 20, partially illustrating the cross section IV-IV in Figure 3.

As shown in Figures 2 and 3, the electronic stamp 20 comprises a case 200, a conductive member 300, and a bottom plate 220.

The case 200 is the component that forms the outer shape of the electronic stamp 20 and is a container that houses the conductive member 300 inside. The case 200 is made of an insulating material such as resin. The case 200 is roughly cuboid in shape. As shown in Figure 3, an opening is formed in the bottom portion of the case 200, and this opening is covered by the bottom plate 220, which will be described later.

As shown in FIG. 2 , a rectangular opening 215 is formed on each of the four side surfaces of the case 200. This allows the surface of the conductive member 300 housed inside to be exposed to the outside through each opening 215. When a user holds the electronic stamp 20 to make a stamp, the user's finger comes into contact with the surface of the conductive member 300 through one of the openings 215.

The top surface 210 of the case 200 is the surface that will be on the upper side when a stamp is made, i.e., the surface that will be located opposite the display unit 410. Four designs 211, 212, 213, and 214 are drawn on the top surface 210 in a circular pattern. In this embodiment, design 211 is a heart, design 212 is a clover, design 213 is a diamond, and design 214 is a spade. These are merely examples, and the designs drawn on the top surface 210 may be different. As will be explained later, these designs 211 and the like correspond to images that will be displayed on the display unit 410 when a stamp is made.

The conductive member 300 is a conductive member, such as a conductive resin. The conductive member 300 is housed inside the case 200 and the bottom plate 220, and as mentioned above, a portion of it is exposed to the outside through the opening 215.

The conductive member 300 has three protrusions 311 formed on it that protrude toward the bottom plate 220 (i.e., downward). In this embodiment, each of the protrusions 311 is cylindrical, but may have other shapes. When viewed from the bottom side as shown in Figure 3, the protrusions 311 are located near three of the four corners of the rectangular case 200, and are not located near the remaining corner. Each of the protrusions 311 is exposed to the outside through an opening 223 formed in the bottom plate 220, which will be described next.

The bottom plate 220 is a plate-like member arranged to cover the conductive member 300 from below. Like the case 200, the bottom plate 220 is formed of an insulating material such as resin. The bottom plate 220 has the aforementioned openings 223 formed in positions corresponding to the protrusions 311. When viewed from the bottom side as in Figure 3, each opening 223 is formed in an area that includes the entire protrusion 311 directly below it.

The bottom plate 220 has a flat portion 221 and an inclined portion 222. The flat portion 221 occupies the majority of the bottom plate 220 and is parallel to the top surface 210 of the case 200. The flat portion 221 is the portion that faces the display unit 410 when the electronic stamp 20 is imprinted, i.e., the portion that is generally parallel to the display unit 410, and corresponds to the "flat portion" in this embodiment.

The inclined portions 222 are portions that are inclined relative to the top surface 210 of the case 200. The inclined portions 222 are provided near each of the four corners of the bottom plate 220. Three of the four inclined portions 222 have the openings 223 described above formed in them. As shown in Figure 4, the inclined portions 222 are inclined so that they approach the inside (i.e., the top surface 210) as they move toward the distal end.

Figure 4 (A) shows the state of the bottom plate 220 and other components before stamping, i.e., when the electronic stamp 20 has not yet come into contact with the display unit 410. One end of a rod-shaped support 224 extending inward is connected to the center of the flat plate portion 221. The support 224 is inserted into a through-hole 312 formed in the conductive member 300, and is held in a state in which it can move up and down in Figure 4. However, the end of the support 224 on the top surface 210 side is prevented from coming off by a mechanism (not shown), so the bottom plate 220 will not come off the electronic stamp 20.

In Figure 4, the surface of the conductive member 300 designated by the reference numeral "310" is the surface facing the flat plate portion 221; hereinafter, this surface will also be referred to as "surface 310." Surface 310 is parallel to the upper surface 210 and the flat plate portion 221, and is the surface on which the respective protrusions 311 are provided. When the electronic stamp 20 is imprinted, surface 310 faces the display unit 410 via the flat plate portion 221. Surface 310, like the flat plate portion 221, corresponds to the "flat portion" in this embodiment.

A support surface 201, which is a surface parallel to the top surface 210, is formed on the inside of the case 200, and the tip of the inclined portion 222 is in contact with the support surface 201. In the state shown in Figure 4(A), the tip of the protrusion 311 is located inside the flat portion 221. Therefore, when the electronic stamp 20 is used to imprint, the flat portion 221 is the first to come into contact with the display unit 410.

After the flat portion 221 comes into contact with the display portion 410, if the user presses the electronic stamp 20 further toward the display portion 410 (i.e., downward), the portion of the bottom plate 220 near the inclined portion 222 elastically deforms, and the flat portion 221 moves closer to the conductive member 300. Eventually, as shown in Figure 4(B), the outer surface of the flat portion 221 and the tip surfaces of the protrusions 311 are positioned on the same plane. Although the display portion 410 is not shown in the figure, in the state shown in Figure 4(B), the tip surfaces of each protrusion 311 are in contact with the display portion 410.

At this time, part of the conductive member 300 is in contact with the user's hand, and the other part, the protrusion 311, is in contact with the display unit 410. Therefore, the control unit 450 can detect that the conductive member 300 has come into contact with the display unit 410, i.e., that a stamp has been made.

When the stamping is complete and the electronic stamp 20 is removed from the display unit 410, the bottom plate 220 returns to the state shown in Figure 4 (A).

The configuration of the control unit 450 will be described with reference to Figure 5. As previously mentioned, the control unit 450 is a part that controls the operation of the entire display device 40, including the display unit 410. The control unit 450 is configured as a computer system that includes a CPU, ROM, RAM, etc. (not shown). The control unit 450 has the following functional elements: a stamp detection unit 451, a determination unit 452, a selection unit 453, a processing unit 454, and a memory unit 455.

The stamp detection unit 451 is a part that performs processing to detect stamping of the electronic stamp 20. When the electronic stamp 20 is stamped, the stamp detection unit 451 detects this and also detects the position where the stamp was made on the display unit 410. The "position where the stamp was made" refers to the respective positions of the three protrusions 311 that come into contact with the display unit 410. Note that the detection method used by the stamp detection unit 451 can be a conventional detection method used on a touch panel screen, so a detailed description of this method will be omitted.

Hereinafter, the center of the upper surface 210 will also be referred to as "center C1" (see FIG. 2).
When the electronic stamp 20 is rotated around an axis that passes through the center C1 and is perpendicular to the top surface 210, the orientation of the electronic stamp 20 changes accordingly. When the "orientation" of the electronic stamp 20 is defined in this way, the determination unit 452 is a part that performs processing to determine the orientation of the affixed electronic stamp 20.

As explained with reference to Figure 3, in this embodiment, protrusions 311 are provided near three of the four corners of the rectangular case 200. Therefore, if the positions of the three protrusions 311 that come into contact with the display unit 410 when a stamp is made are known, the orientation of the electronic stamp 20 in that state will be uniquely determined. Therefore, the determination unit 452 is configured to determine the orientation of the electronic stamp 20 based on the positions of the protrusions 311 detected by the stamp detection unit 451.

Note that the number and arrangement of the protrusions 311 may differ from that of this embodiment, provided that the correspondence between the position of each protrusion 311 and the orientation of the electronic stamp 20 when imprinting is uniquely determined. Such an arrangement of the protrusions 311 can be described as having one-fold symmetry or one-fold rotational symmetry with respect to an axis that passes through the center C1 and is perpendicular to the top surface 210.

The selection unit 453 is a part that performs processing to select an image to be displayed on the display unit 410 according to the "orientation" of the electronic stamp 20 determined by the determination unit 452. The "image" here refers to the image that is displayed on the display unit 410 at the position where the stamp is stamped when the stamp is made. In this embodiment, four candidates are prepared in advance as the image to be displayed on the display unit 410, and only one image selected from these candidates by the selection unit 453 is displayed on the display unit 410.

The heart image 50 shown in Figure 1 is one of these candidates. In this embodiment, four images - a heart, a clover, a diamond, and a spade - are prepared in advance as the candidates. These four candidates correspond to the four designs 211, 212, 213, and 214 depicted on the top surface 210. In other words, designs corresponding to the image candidates displayed on the display unit 410 are depicted on the top surface 210 in a circular arrangement. The correspondence between the orientation of the electronic stamp 20 when imprinting and the image selected by the selection unit 453 will be explained later.

The processing unit 454 is a part that performs processing to display the image selected by the selection unit 453 on the display unit 410. The processing unit 454 displays the image selected by the selection unit 453 at the position on the display unit 410 where the stamp was made. The image remains displayed on the display unit 410 even after the electronic stamp 20 is moved away from the display unit 410.

The memory unit 455 is a non-volatile storage device provided in the control unit 450, such as an SSD. The memory unit 455 stores programs and data necessary for the processing performed by the control unit 450. The data stored in the memory unit 455 includes, for example, image data displayed on the display unit 410.

The specific details of the processing executed by the control unit 450 will be explained with reference to the flowchart in Figure 6. The series of processing shown in Figure 6 begins execution immediately after the electronic stamp 20 is applied.

The first step S01 of this process involves obtaining the center position of the stamp. The "center position of the stamp" refers to the position of a point on the display unit 410 that is directly below the center C1 of the electronic stamp 20 when the display unit 410 is viewed along its normal direction. The center position of the stamp can be obtained based on the positions of the respective protrusions 311 when the stamp is made.

In step S02 following step S01, it is determined whether the center position of the stamp is within a predetermined range of the display unit 410. The "predetermined range" is the range surrounded by the dotted line marked with the letter "D" in Figure 7. Hereinafter, this range will also be referred to as "range D."

Here, the long side along the horizontal direction of the display unit 410 is side 411, and the short side along the vertical direction of the display unit 410 is side 412. The distance from range D to side 411 is T, and the distance from range D to side 412 is also T.

7, if the length of one side of the image 50 displayed on the display unit 410 when the seal is stamped is L, the following formula (1) holds between L and T. In other words, T and the range D are set so that the following formula (1) holds.
T=L/2 ^1/2 ...(1)

The above T is the length from the center C2 of the image 50 to the corner, i.e., the length equal to x shown in Figure 7.

In this embodiment, when an imprint is made using the electronic stamp 20, the image 50 is displayed in a position where the center C2 of the image 50 is directly below the center C1 of the electronic stamp 20. In other words, the center position of the imprint and the center C2 of the image 50 are aligned.

In step S02 of Figure 6, if the center position of the stamp is outside range D, the process shown in Figure 6 ends without performing the process of displaying an image on the display unit 410.

The reason for this will be explained. In this embodiment, the display unit 410 is configured to display the image 50 at an angle that matches the orientation of the electronic stamp 20 at the time of imprinting. Therefore, depending on the orientation of the electronic stamp 20, the image 50 may be displayed at an angle so that the diagonal line corresponding to x in Figure 7 is parallel to the side 411. In this case, if the center position of the imprint is outside of range D, part of the image 50 will extend outside the display unit 410, and the entire image 50 cannot be displayed.

Therefore, in this embodiment, if the position of the electronic stamp 20 when it is stamped (i.e., the center position of the stamp) is outside the range D of the display unit 410, the processing unit 454 does not perform processing to display the image 50 on the display unit 410. This makes it possible to display the entire image 50 in the same position as the stamped location, regardless of the orientation of the electronic stamp 20 when it is stamped.

Note that if there is no problem with only a portion of image 50 being displayed, the processing of step S02 in Figure 6 does not need to be performed.

If, in step S02, the center position of the stamp is determined to be within range D, the process proceeds to step S03. In step S03, the determination unit 452 calculates the angle of the electronic stamp 20 when the stamp was made.

Figure 8 shows the electronic stamp 20 and display unit 410 when a seal is applied. DR1 shown in the figure is parallel to the planar portion of the electronic stamp 20 (flat portion 221 and surface 310) and represents a virtual direction fixed relative to the electronic stamp 20. Here, DR1 is the direction from the center C1 perpendicular to the side near the design 211. Because DR1 is a virtual direction fixed relative to the electronic stamp 20, it changes depending on the orientation of the electronic stamp 20. DR1 corresponds to the "first direction" in this embodiment.

DR2 shown in FIG. 8 is parallel to the top surface of the display unit 410 and represents a virtual direction fixed relative to the display unit 410. Here, the direction parallel to the side 411 and running from the left side to the right side in FIG. 8 is taken as DR2. Because DR2 is a virtual direction fixed relative to the display unit 410, it does not change depending on the orientation of the electronic stamp 20. DR2 corresponds to the "second direction" in this embodiment.

In step S03 of Figure 6, the angle θ between DR1 and DR2 is calculated and acquired as the "angle of the electronic stamp 20." This process is performed by the determination unit 452. The angle θ can be calculated based on the positions of the protrusions 311 that contact the display unit 410 when the stamp is imprinted.

The determination unit 452 determines the orientation of the electronic stamp 20 based on the angle θ described above. In this embodiment, the angle θ is used as an index that indicates the orientation of the electronic stamp 20 itself.

In step S04 following step S03, the selection unit 453 selects an image to be displayed on the display unit 410. Figure 9 shows a map indicating the correspondence between the angle θ calculated in step S03 and the image to be displayed. This map is created in advance and stored in the memory unit 455. The selection unit 453 selects an image by referring to this map.

As shown in Figure 9, if the angle θ is greater than or equal to -45 degrees and less than 45 degrees, an image of a spade is selected. If the angle θ is greater than or equal to 45 degrees and less than 135 degrees, an image of a heart is selected. If the angle θ is greater than or equal to 135 degrees and less than 225 degrees, an image of a clover is selected. If the angle θ is greater than or equal to 225 degrees and less than 315 degrees, an image of a diamond is selected.

When the angle θ is greater than or equal to -45 degrees and less than 45 degrees, the spade symbol 214 is located at the farthest position from the user's perspective. In other words, the spade image selected at this time is the image corresponding to the symbol 214 located at the farthest position from the user's perspective. The same applies when the angle θ is other values. In other words, the heart image selected when the angle θ is greater than or equal to 45 degrees and less than 135 degrees is the image corresponding to the symbol 211 located at the farthest position from the user's perspective. The clover image selected when the angle θ is greater than or equal to 135 degrees and less than 225 degrees is the image corresponding to the symbol 212 located at the farthest position from the user's perspective. The diamond image selected when the angle θ is greater than or equal to 225 degrees and less than 315 degrees is the image corresponding to the symbol 213 located at the farthest position from the user's perspective.

In this way, the selection unit 453 of this embodiment is configured to select, when a stamp is made, the image to be displayed on the display unit 410, which corresponds to the design 211, etc., that is located at the farthest back as seen from the user.

After an image is selected in step S04 of FIG. 6, the process proceeds to step S05. In step S05, the processing unit 454 performs processing to display the image selected in step S04 on the display unit 410. As previously mentioned, the position at which the image is displayed is the position at which the stamp was made. The image is also displayed tilted appropriately to match the orientation of the electronic stamp 20 at the time of stamping. For example, if the angle θ is 30 degrees, the image of a spade corresponding to design 214 is displayed tilted 30 degrees to the left. If the angle θ is 60 degrees, the image of a heart corresponding to design 211 is displayed tilted 30 degrees to the right.

As described above, with the electronic stamp device 10 according to this embodiment, the user can switch the image displayed when stamping simply by changing the orientation of the electronic stamp 20. Since there is no need to provide a mechanism such as a selector switch to allow the user to select an image from multiple candidates, the structure of the electronic stamp device 10 does not become complicated.

In this embodiment, four candidate images are prepared in advance for display on the display unit 410, and four corresponding designs 211 are drawn on the top surface 210. The number of candidate images displayed on the display unit 410 may be three or less, or five or more. In either case, the same number of designs corresponding to the candidate images are drawn on the top surface 210. In this case, it is preferable that the shape of the case 200 when viewed from above (i.e., the shape of the top surface 210) be a polygon corresponding to the number of designs. For example, if there are five designs, the top surface 210 should be a pentagon. In this case, the image displayed when stamping can be changed every time the angle θ changes by 72 degrees (= 360 degrees / 5). The same applies to cases where the number of designs is other than five. In either case, the design drawn on the top surface 210 only needs to correspond to the image, and does not have to be the same as the image.

Other advantages will now be explained. As explained with reference to Figure 4, when stamping is performed on the electronic stamp 20, the flat plate portion 221 comes into contact with the display unit before the protrusion 311. The flat plate portion 221 corresponds to the "contact portion" in this embodiment.

When stamping, the inclined portion 222 functions as a leaf spring, urging the flat portion 221 toward the display unit 410. The user stamps while applying force against the elastic force of the inclined portion 222, causing the protrusion 311 to contact the display unit 410. The inclined portion 222 corresponds to the "urging portion" in this embodiment. In this embodiment, the flat portion 221, which is the contact portion, and the inclined portion 222, which is the urging portion, are integrated with each other. The "urging portion" may be a leaf spring as in this embodiment, but may also be other elastic members (for example, a spiral spring, a member that uses air pressure, an iron spring, etc.).

In this configuration, if the user simply places the electronic stamp 20 on the display unit 410, the protrusion 311 will not come into contact with the display unit 410, so no stamping will occur and no image will be displayed on the display unit 410. This makes it possible to prevent stamping from occurring against the user's intention.

The present embodiment has been described above with reference to specific examples. However, the present disclosure is not limited to these specific examples. Design modifications to these specific examples made by a person skilled in the art as appropriate are also included within the scope of the present disclosure as long as they comprise the features of the present disclosure. The elements of the above-mentioned specific examples, as well as their arrangement, conditions, shape, etc., are not limited to those exemplified and can be modified as appropriate. The elements of the above-mentioned specific examples can be combined in different ways as appropriate, as long as no technical contradictions arise.
