Summary of the Invention

Problems to be Solved by the Invention

[0004] Incidentally, in recent years, there has been an increasing demand for improved design and information diversity in such badges. For example, since the original character to be displayed is a digital image, there is an expectation that the badge will also display a digital image or an image that is very close to a digital image. However, badges such as those in Patent Documents 4 and 5 only have means for lighting up LEDs or displaying the time, and have not been able to provide a badge that can meet such expectations. Furthermore, even if a liquid crystal or the like capable of displaying an image is provided on the surface of the badge, if a circuit board equipped with the electronic components necessary for image display and a power supply are to be mounted, the thickness of the badge will increase, or the width of the badge will increase, compromising the characteristics of a small and aesthetically pleasing badge. Also, if miniaturization is prioritized, there is a problem that it may not be possible to mount the electronic components necessary for display, or a power supply that can provide sufficient power may not be possible.

[0005] Therefore, this invention provides a badge that is small in size and capable of displaying images. [Means for solving the problem]

[0006] A badge according to the first aspect of the present invention comprises a housing having a display section and a storage section formed inside, The housing comprises a substrate unit housed in the housing and a power supply unit housed in the housing and supplying power to the display unit. The housing has a front section which includes the display unit in at least a portion of it, a rear section which is located on the opposite side of the housing from the front section, and a side wall section which is located between the front section and the rear section and is arranged along the periphery of the front section and the rear section. The substrate unit has a first peripheral edge which runs along a part of the inner surface of the side wall section when viewed in the front-to-back direction, and a second peripheral edge which connects both ends of the first peripheral edge, and an IC chip which is arranged on the substrate and controls the display of the display unit. The power supply unit is located in the housing, in the second region of the housing, when viewed in the front-to-back direction, between a first region where the substrate is located and which is partitioned by the second peripheral edge of the substrate, and a second region other than the first region.

[0007] With this configuration, the circuit board housed in the enclosure is divided into a first region and a second region by a second peripheral edge. In the first region, the first peripheral edge is positioned along the inner surface of the side wall, allowing for effective use of the first region and securing the circuit area necessary for display control of the display unit on the circuit board. Therefore, the area of ​​the first region can be made as small as possible while still securing the area necessary for display control of the display unit, and as a result, the area of ​​the second region can be made as large as possible. Consequently, it is possible to secure the maximum possible space for the power supply unit to supply the power required for the display unit in the second region. For this reason, in the badge with this configuration, the function of displaying an image on the display unit can be secured while making the entire badge smaller.

[0008] Furthermore, in the badge of the second embodiment, the front portion and the rear portion are formed in a circular shape when viewed in the front-to-rear direction, the side wall portion is arranged along the circular periphery of the front portion and the rear portion, and the first periphery of the substrate is formed in an arc.

[0009] With this configuration, when viewed from the front or back, the design is good as a circular badge, and in the space of the housing which is circular when viewed from the front or back, the circuit area necessary for display control of the display unit can be secured on the substrate by a substrate in which the first peripheral edge is formed in an arc shape.

[0010] Furthermore, in the third embodiment of the badge, the power supply unit has a pair of terminals arranged on both sides along the second peripheral portion, and a battery holder capable of housing a battery connected to the pair of terminals.

[0011] With this configuration, the pair of terminals are arranged on both sides along the second periphery, which allows for the largest possible spacing between the terminals where the battery is placed, making it possible to place a battery with the largest possible capacity within the limited space of the second region in the housing.

[0012] Furthermore, in the fourth embodiment of the badge, the battery holder portion is capable of accommodating a battery with a size equivalent to or smaller than that of an AAA battery.

[0013] This configuration allows for the placement of batteries up to the size of an AAA battery, thereby ensuring the necessary power and capacity for the display unit.

[0014] Furthermore, in the fifth embodiment of the badge, the substrate is positioned on the upper side in the vertical direction, and the pair of terminals are provided such that the center of gravity of the battery located in the power supply unit is positioned below the center of gravity of the housing when viewed in the front-to-back direction.

[0015] With this configuration, the circuit board is positioned on the upper side in the vertical direction, allowing the second region where the power supply unit is located to be positioned on the lower side. Furthermore, by positioning the center of gravity of the battery, which is relatively heavy compared to other components and is located in the power supply unit, below the center of gravity of the housing, the overall center of gravity can be placed near or below the center of gravity of the housing when viewed in the front-to-back direction, thereby improving stability when attached to clothing or bags. In addition, when the first region is placed on the upper side and the second region on the lower side and placed on a surface, it becomes easier to place it stably.

[0016] Furthermore, the badge of the sixth embodiment includes an operating section provided on the rear surface, and the operating section and the substrate are arranged to overlap when viewed in the front-to-back direction.

[0017] With this configuration, the control unit and the circuit board are arranged to overlap when viewed from the front to back, allowing the control unit and the electronic components on the circuit board that are connected to the control unit to be installed in a limited space without requiring a complex connection structure.

[0018] Furthermore, in the seventh embodiment of the badge, the substrate has a first surface on which the IC chip is arranged and a second surface located on the opposite side of the first surface, with the first surface facing the rear side.

[0019] According to this configuration, a simpler connection structure can be achieved between the operation unit and the electronic components on the substrate that are coordinated with the operation unit, and it is possible to suppress the complication of the circuit layout between the IC chip that controls the display unit and the electronic components that are coordinated with the operation unit.

[0020] In addition, the badge according to the eighth aspect includes a display wiring that connects between the display unit and the IC chip, and a through hole for the substrate is formed in the substrate that penetrates from the first surface to the second surface and through which the display wiring is inserted.

[0021] According to this configuration, the display unit and the IC chip on the opposite sides with the substrate sandwiched therebetween can be connected by the display wiring passing through the through hole for the substrate.

[0022] In addition, the badge according to the ninth aspect has an operation main body portion that is formed in a circular shape when viewed in the front-rear direction and extends in the front-rear direction, and a ridge portion that protrudes in a direction intersecting the front-rear direction from the operation main body portion and extends in the front-rear direction. A guide hole that penetrates from the accommodation portion to the outside rearward in the front-rear direction is formed in the rear surface portion. The guide hole has an operation main body hole through which the operation main body portion is inserted and a groove portion through which the ridge portion is inserted when viewed in the front-rear direction, and the operation unit can move forward and backward only in the front-rear direction within the guide hole.

[0023] According to this configuration, the operation unit can be moved forward and backward in the front-rear direction within the guide hole in response to an operation input to the operation unit, and thereby the electronic components that detect the operation input on the substrate and the operation unit can be coordinated based on the forward and backward movement of the operation unit. Here, the operation unit has an operation main body portion and a ridge portion. The operation main body portion is inserted into the operation main body hole and can move forward and backward in the front-rear direction, and the ridge portion that protrudes in a direction intersecting the front-rear direction from the operation main body portion can move forward and backward in the front-rear direction within the groove portion. Therefore, as a whole operation unit, while being able to move forward and backward in the front-rear direction, the ridge portion can be locked by the groove portion around the axis in the front-rear direction, thereby preventing rotation or rattling around the axis, and there is no need to separately provide a guiding or anti-rotation member.

[0024] ]The badge according to the tenth aspect has a weight disposed in the second region in the housing portion, and the center of gravity position is located below the center of gravity of the housing when viewed in the front-rear direction.

[0025] According to this configuration, by positioning the center of gravity position of the weight below the center of gravity of the housing, the overall center of gravity can be made near the center of gravity of the housing or below the center of gravity of the housing when viewed in the front-rear direction, and the stability when attached to clothing, a backpack, etc. can be improved. Also, when placing the badge on a surface with the first region on the upper side and the second region on the lower side, it becomes easier to place stably.

[0026] In the badge according to the eleventh aspect, a flat surface portion is formed on a part of the outer surface of the side wall portion on the lower side in the vertical direction.

[0027] According to this configuration, when placing the badge on a surface, by placing the flat surface portion on the surface to be placed, it becomes easier to place stably.

Effect of the Invention

[0028] The present invention can provide a badge that is small and capable of displaying an image.

[0030] Next, embodiments of the present invention will be described based on the drawings. In the embodiments and modified examples described below, corresponding components may be denoted by the same reference numerals and their descriptions may be omitted.

[0031] As shown in Figures 1 to 6, the badge 1 according to this embodiment can be attached to a mounting target part A, such as clothing or a bag, and can display patterns and various information depending on the intended use of the badge 1. Here, in the badge 1, the side on which patterns and information are displayed is defined as the front side X1, and the side attached to the mounting target part A is defined as the rear side X2, with the direction from the front side X1 to the rear side X2 being defined as the front-to-back direction X. Furthermore, the up-and-down direction Z and the left-to-right direction Y are defined according to the direction in which the badge 1 faces when it is attached to a vertical surface.

[0032] Badge 1 comprises a housing 10 with an internal housing section 10A, a circuit board section 50 housed in the housing section 10A, a power supply section 80 housed in the housing section 10A, and an operation section 90. The housing 10 has a display section 11 on its front side X1 in the front-to-back direction X that displays patterns and information. The display section 11 is, for example, a liquid crystal display circuit board. The power supply section 80 supplies power to the display section 11.

[0033] The housing 10 has a front portion 20 located on the front side X1 in the front-rear direction X, a rear portion 30 positioned on the opposite side of the housing portion 10A from the front portion 20, and a side wall portion 40 positioned between the front portion 20 and the rear portion 30 along the periphery 20a, 30a of the front portion 20 and the rear portion 30. In this embodiment, the front portion 20 and the rear portion 30 are formed in a circular shape when viewed in the front-rear direction X. The front portion 20 has an annularly formed frame member 21 and a display portion 11 fitted into the frame member 21.

[0034] The rear portion 30 has a rear main body portion 31 and a lid portion 35 attached to the rear main body portion 31. The rear main body portion 31 has a first portion 32 located on the upper side Z1 in the vertical direction Z and a second portion 33 located on the lower side Z2 in the vertical direction Z. In the housing 10, the first portion 32 constitutes the portion exposed to the rear side X2. The first portion 32 is provided with a mounting portion 32a that extends in the left-right direction Y and protrudes to the rear side X2 in the front-rear direction X. The mounting portion 32a is located on the upper side Z1 in the vertical direction Z. The mounting portion 32a has a through hole 32b that penetrates in the left-right direction Y. A safety pin 95, which is a locking member for attaching to the mounting target portion A, is inserted through the through hole 32b. The first portion 32 also has a guide hole 32c that penetrates outward from the housing portion 10A to the rear side X2 in the front-rear direction X.

[0035] A step equal to the thickness of the lid portion 35 is formed between the first portion 32 and the second portion 33. The lid portion 35 is fitted and attached to the second portion 33. Two claw members 35a protrude toward the first portion 32 from the portion of the lid portion 35 that faces the first portion 32, spaced apart in the left-right direction Y. On the second portion 33 side of the first portion 32, i.e., the portion where the step is formed, fitting holes 31a are formed at positions corresponding to the claw members 35a into which the claw members 35a fit. In other words, the lid portion 35 is attached to the second portion 33 of the rear body portion 31 by the claw members 35a fitting into the fitting holes 31a.

[0036] The second part 33 has an opening 33a that opens to the rear side X2 in the front-rear direction X. The opening 33a is for removing the battery E located in the power supply unit 80, as will be described later. The opening 33a is closed when the cover 35 is attached to the second part 33.

[0037] In this embodiment, the side wall portion 40 is formed in a cylindrical shape. The frame member 21 of the front portion 20 is attached to the front end of the side wall portion 40 by fitting it into a fitting recess 21a formed in the frame member 21. At its rear end, the side wall portion 40 is connected to the peripheral edge 30a of the rear portion 30. In this embodiment, the side wall portion 40 is integrally molded with the rear main body portion 31 of the rear portion 30.

[0038] The operating section 90 is inserted through the guide hole 32c. The operating section 90 has an operating body portion 91 extending in the front-rear direction X, and a protruding ridge portion 92 that protrudes from the operating body portion 91 in a direction intersecting the front-rear direction X and also extends in the front-rear direction X. In this embodiment, the operating body portion 91 is formed in a circular shape when viewed in a cross-sectional view in the front-rear direction X. In this embodiment, the protruding ridge portion 92 is formed in a rectangular shape when viewed in a cross-sectional view in the front-rear direction X, and protrudes from the operating body portion 91 on the lower side Z2 in the vertical direction Z.

[0039] Here, the guide hole 32c formed in the first part 32 has an operating body hole 32d through which the operating body portion 91 is inserted, and a groove portion 32e through which the protruding portion 92 is inserted. When viewed in a cross-sectional view in the front-rear direction X, the guide hole 32c matches the cross-sectional shape of the operating portion 90, and thereby the guide hole 32c guides the operating portion 90 so that it can move back and forth in the front-rear direction X. That is, when viewed in a cross-sectional view in the front-rear direction X, the operating body hole 32d of the guide hole 32c is formed in a circular shape, and the protruding portion 92 is formed in a rectangular shape. The operating body portion 91 of the operating portion 90 and the operating body hole 32d of the guide hole 32c are located between the opening 33a and the mounting portion 32a to which the safety pin 95 is attached. When viewed in a cross-sectional view in the front-rear direction X, the operating body portion 91 of the operating portion 90 and the operating body hole 32d of the guide hole 32c are located above Z1 in the vertical direction Z from the center of the circular housing 10.

[0040] The substrate portion 50 is mounted and fixed on a substrate mounting surface 41 which is a part of the side wall portion 40 and is formed to protrude from the inner surface of the side wall portion 40 and faces the front X1 in the front-rear direction X. The substrate portion 50 includes a substrate 51, an IC chip 52 mounted on the substrate 51 for controlling the display of the display unit 11, a switch 53, a contact sensor 54 for detecting contact of the switch 53, and a connector 55.

[0041] The substrate 51 has a first surface 51a and a second surface 51b. In this embodiment, all electronic components such as the IC chip 52, switch 53, contact sensor 54, connector 55, and printed wiring connecting them are mounted on the first surface 51a. For this reason, no electronic components are mounted on the second surface 51b. Note that the wiring is not shown in the illustration. The first surface 51a faces the rear side X2 in the front-to-back direction X, and the second surface 51b faces the front side X1 in the front-to-back direction X. That is, the first surface 51a faces the rear surface 30 on which the operating section 90 is provided, and the second surface 51b faces the front surface 20 on which the display section 11 is provided. In addition, a through-hole 51c is formed in the substrate 51 that penetrates from the first surface 51a to the second surface 51b.

[0042] The substrate 51 has a first peripheral edge 51d and a second peripheral edge 51e when viewed in the front-to-back direction X. The first peripheral edge 51d is positioned along a part of the inner surface of the side wall 40. Specifically, in this embodiment, the first peripheral edge 51d is positioned along the upper Z1 portion of the inner surface of the side wall 40 in the vertical direction Z. The side wall 40 in this embodiment is formed in a cylindrical shape, and its inner surface is formed in an arc shape when viewed in the front-to-back direction X. In this embodiment, the first peripheral edge 51d is formed in an arc shape so as to conform to the shape of the inner surface of the side wall 40, in other words, to be parallel to it. The second peripheral edge 51e is positioned to connect the two ends 51f and 51g of the first peripheral edge 51d, and in this embodiment, it is formed in a straight line. In this embodiment, the second peripheral edge 51e and the first peripheral edge 51d are connected via a notch 51h. The notch 51h of the substrate 51 is formed in a straight line extending in the vertical direction Z.

[0043] When viewed in the front-to-back direction X, the housing section 10A is divided into a first region P on the upper side Z1 and a second region Q on the lower side Z2 by a virtual line L extending the second peripheral edge 51e in the vertical direction Z. The substrate 51 is located in the first region P. On the other hand, the power supply unit 80 is located in the second region Q.

[0044] The power supply unit 80 has a battery storage section (battery holder) 81 for housing the battery E, and a pair of terminals 82, 82. The battery storage section 81 has a storage recess 81a formed to match the shape of the battery E so that it can accommodate the battery E to be used. The storage recess 81a communicates with the opening 33a of the second part 33 of the rear section 30. Therefore, with the lid 35 removed, the battery E can be inserted into and removed from the storage recess 81a through the opening 33a. When the battery E is placed in the storage recess 81a, the battery storage section 81 is positioned such that, when viewed in the front-to-back direction X, the center of gravity of the battery E is located below the center of gravity of the housing 10 in the vertical direction Z2. The battery storage section 81 is integrally molded with the rear main body section 31 of the rear section 30.

[0045] The battery E used in this embodiment is equivalent to a AAA-type battery. The battery can be either a non-rechargeable or rechargeable battery, and its power and capacity can be appropriately selected within the range that can be accommodated in the 10A storage section. For example, a larger AA-type battery or a battery other than a cylindrical battery may be selected. Batteries equivalent to AAA-type batteries include not only AAA-type batteries but also batteries conforming to "AAA" specifications. In the case of a AAA-type battery, it is cylindrical in shape with positive and negative terminals on the end face. The battery E used in this embodiment, for example, has a diameter of approximately 10.5 mm and a total length of approximately 44.5 mm. The voltage is approximately 1.5V for a dry cell battery and approximately 1.2V for a nickel-metal hydride rechargeable battery.

[0046] The pair of terminals 82, 82 are spaced apart in the left-right direction Y, and can be connected to both terminals of the battery E housed in the battery compartment 81. The pair of terminals 82, 82 extend toward the circuit board 51 and are fixed to the first surface 51a of the circuit board 51. The pair of terminals 82, 82 are electrically connected to the switch 53 and the IC chip 52 via wiring (not shown) arranged on the first surface 51a of the circuit board 51.

[0047] From the display unit 11, a display wiring 12 for supplying power to the display unit 11 and a detection wiring 13 for sending a detection signal for touch operation on the display unit 11 extend. The display wiring 12 is routed through a through-hole 51c in the substrate from the second surface 51b to the first surface 51a. The terminals at the ends of the display wiring 12 are connected to a connector 55 provided on the first surface 51a. In this embodiment, since touch panel operation on the display unit 11 is not used, the ends of the detection wiring 13 are not electrically connected to the substrate 51.

[0048] The IC chip 52 in this embodiment has a non-volatile memory area inside which image data to be displayed on the display unit 11 is pre-recorded. The image data is not particularly limited, but examples include characters, patterns, text information, symbol information, and combinations thereof. In this embodiment, multiple image data is recorded in the IC chip 52. The IC chip 52 operates using power supplied from the power supply unit 80 and performs display control to display the recorded image data on the display unit 11.

[0049] Here, the circuit board 51 and the operating unit 90 are arranged to overlap when viewed in the front-to-back direction X. The switch 53 and the contact sensor 54 are positioned so as to overlap with the operating body 91 of the operating unit 90 when viewed in the front-to-back direction X. The contact sensor 54 is fixed to the first surface 51d of the circuit board 51 at that position. The switch 53 is positioned between the contact sensor 54 and the operating body 91 and is fixed to the first surface 51d of the circuit board 51 so as to straddle the contact sensor 54. Although not shown, the switch 53 is biased to the rear side X2 in the front-to-back direction X, and in its normal position it does not contact the contact sensor 54, but can be pushed to the front side X1 in the front-to-back direction X to advance to an input position where it contacts the contact sensor 54. The front end of the operating body 91 of the operating unit 90 is in contact with the switch 53. When the switch 53 is in the normal position, the rear end of the operating body 91 of the operating section 90 is positioned at the same position as the rear surface of the first portion 32 of the rear surface 30 in the front-rear direction X, or slightly forward X1, that is, slightly recessed relative to the rear surface of the first portion 32.

[0050] In this embodiment, the power can be turned ON / OFF by pressing the operation unit 90 forward in the front direction X1, and allowing a certain period of time to pass while the switch 53 remains in contact with the contact sensor 54, i.e., by long-pressing the operation unit 90. Furthermore, if the switch 53 is released from the contact sensor 54 a short time after contacting it, i.e., by quickly pressing the operation unit 90, the IC chip 52 controls the input image data to the display unit 11, switching from the currently input image data to another image data.

[0051] Furthermore, the badge 1 in this actual form is further equipped with a weight 97. The weight 97 is located in the second region Q within the housing section 10A, and its center of gravity is positioned below the center of gravity of the housing 10 when viewed in the front-to-back direction X.

[0052] As described above, with the badge 1 of this embodiment, the substrate 51 housed in the housing section 10A of the housing 10 has a first peripheral edge 51d positioned along the inner surface of the side wall 40 in the first region P of the second region P, which is divided into a first region P and a second region Q by a second peripheral edge 51e. This effectively utilizes the area of ​​the first region P to secure the circuit layout area necessary for display control of the display unit 11 on the substrate 51. Therefore, the area of ​​the first region P can be made as small as possible while securing the area necessary for display control of the display unit 11, and as a result, the area of ​​the second region Q can be made as large as possible. Consequently, it is possible to secure the maximum space for the power supply unit 80 to supply the power necessary for the display unit 11 in the second region Q. For this reason, with the badge 1 of this configuration, the entire badge 1 can be miniaturized while ensuring the function of displaying an image on the display unit 11.

[0053] Furthermore, when viewed in the front-to-back direction X, the circular badge 1 has good design aesthetics, and the circuit area necessary for display control of the display unit 11 can be secured on the substrate 51 by the substrate 51 in which the first peripheral edge 51d is formed in an arc shape within the space of the circular housing 10A. In the case of modified badges, the first peripheral edge 51d of the substrate 51 can be a shape other than an arc, for example, a polygonal shape composed of multiple straight edges, an ellipse shape, a star shape, and various other shapes can be selected. In addition, even if the shape of the first peripheral edge 51d does not match the shape of the inner surface of the side wall 40, for example, when viewed in the front-to-back direction X, the polygonal first peripheral edge 51d may be arranged to follow the inner surface of the arc-shaped side wall. In this case, increasing the number of sides of the polygon can further enhance the effect. At a minimum, within the housing section 10A, the first peripheral edge 51d of the substrate 51 follows a part of the inner surface of the side wall section 40, thereby effectively utilizing the range of the first region P and securing the circuit layout area necessary for display control of the display unit 11 on the substrate 51.

[0054] Furthermore, since the pair of terminals 82, 82 are arranged on both sides along the second peripheral portion Q, the width between the terminals 82, 82 where the battery E is placed can be made as large as possible, making it possible to place a battery E with the largest possible capacity within the limited space of the second region Q in the housing portion 10A. In addition, by making it possible to place a battery equivalent in size to an AAA battery, the power and capacity required for the display unit 11 can be secured. However, even if the battery size is smaller than that of an AAA battery, it may be adopted from the standpoint of miniaturization if it meets the performance requirements in terms of power supply to the display unit 11 and battery capacity considering usage time.

[0055] Furthermore, because the circuit board 51 is positioned on the upper side Z1 in the vertical direction Z, the second region Q where the power supply unit 80 is located can be positioned on the lower side Z2. By positioning the center of gravity of the battery E, which is relatively heavy compared to other components and is located in the power supply unit 80, on the lower side Z2 relative to the center of gravity of the housing 10, the overall center of gravity can be placed near the center of gravity of the housing 10 when viewed in the front-to-back direction X, or below the center of gravity of the housing 10, thereby improving stability when attached to clothing or bags. Also, when the first region P is positioned on the upper side Z1 and the second region Q on the lower side Z2, it becomes easier to mount it stably. In addition, by using a battery E with a battery size equivalent to an AAA battery and connecting the battery E to the pair of terminals 82, 82 located on both sides along the second peripheral edge 51e, the heavy battery is positioned to extend in the left-to-right direction, resulting in a good overall weight balance. Furthermore, by positioning the center of gravity of weight 97 below the center of gravity of the housing, the overall center of gravity can be placed near the center of gravity of housing 10 when viewed in the front-to-back direction X, or below the center of gravity of housing 10 Z2, thereby improving stability when attached to clothing or bags. In addition, when the first region P is placed on a surface with the upper side Z1 and the second region Q on the lower side Z2, it becomes easier to place it stably.

[0056] Furthermore, when placing the badge on a surface, in addition to the means of adjusting the center of gravity as described above, means such as those shown in Figure 7 may be used to ensure stable placement. Specifically, as shown in Figure 7, in the modified example 1 of the badge 100, a flat portion 101 is formed on a part of the lower Z2 in the vertical direction Z of the outer surface of the side wall portion 40. In this modified example, the flat portion 101 is formed not only on the outer surface of the side wall portion 40, but also on a part of the lid portion 35 connected to the side wall portion 40 and a part of the frame member 21 of the front portion 20. The flat portion 101 protrudes from the side wall portion 40 on both sides in the left-right direction Y, forming a plane that contacts the outer circumferential surface of the frame member 21 at the lowest end of the side wall portion 40. With this configuration, when placing the badge 100 on a surface, placing the flat portion 101 on the surface makes it easier to place it stably. Furthermore, the flat portion is not limited to being formed by protruding from the outer circumferential surface as described above, but may also be formed by cutting out a part of the outer circumferential surface.

[0057] Furthermore, because the operating unit 90 and the circuit board 51 are arranged to overlap when viewed in the front-to-back X direction, the operating unit 90 and the electronic components on the circuit board 51 that are linked to the operating unit 90 can be installed in a limited space without a complex connection structure. In addition, because the first surface 51a on which the IC chip 52 is located faces the rear, the connection structure between the operating unit 90 and the electronic components on the circuit board 51 linked to the operating unit 90, namely the switch 53 and the contact sensor 54, can be made simpler, and the complexity of the circuit arrangement between the IC chip 52 that controls the display unit 11 and the switch 53 and contact sensor 54 linked to the operating unit 90 can be suppressed. Moreover, because the first surface 51a on which the IC chip 52 and other electronic components are located faces away from the display unit 11, electromagnetic compatibility (EMC) between the display unit 11 and the electronic components on the circuit board 51 can be improved, and therefore the distance between the circuit board 51 and the display unit 11 can be minimized, allowing for further miniaturization. Even with this arrangement on the substrate 51, through-holes 51c are formed in the substrate 51, and the display unit 11 and the IC chip 52 on the opposite side of the substrate 51 can be connected by display wiring 12 passing through these through-holes 51c.

[0058] In this embodiment, the image data to be displayed on the display unit 11 is stored in a non-volatile memory located inside the IC chip 52. In this embodiment, the structure does not include external input / output ports such as a USB interface. This allows for a simple configuration, and also restricts the retrieval of stored image data from input / output ports, thereby contributing to the protection of intellectual property related to the images. In this embodiment, the configuration does not include input / output ports, but a configuration with input / output ports is also possible. Furthermore, although the image data is recorded on the IC chip 52, a separate memory may be provided on the substrate, the image data may be recorded in that memory, and the IC chip may read and use the image data from that memory. In addition, in this embodiment, the display unit 11 is a liquid crystal display substrate with touch panel functionality, but since the touch panel functionality is not used, the detection wiring 13 is not connected to the substrate 51. By using a liquid crystal display substrate with touch panel functionality even though the touch panel functionality is not used, costs can be reduced compared to using a liquid crystal display substrate with display functionality only, especially when liquid crystal display substrates with touch panel functionality are cheaper in the market. Furthermore, this embodiment is not limited to a configuration without touch panel functionality; a configuration in which detection wiring 13 is connected to the circuit board 51 to provide touch panel functionality is also possible. Alternatively, a liquid crystal panel display board with only display functionality may be used.

[0059] Furthermore, the operating unit 90, which consists of an operating body portion 91 and a protruding portion 92, and the guide hole 32c, which consists of an operating body hole 32d and a groove portion 32e, allow the operating unit 90 to move back and forth in the front-rear direction X within the guide hole 32c in response to an operation input to the operating unit 90. This enables the operating unit 90 to be linked with an electronic component on the substrate 51 that detects the operation input based on the movement of the operating unit 90. Here, the operating unit 90 has an operating body portion 91 and a protruding portion 92, the operating body portion 91 is inserted through the operating body hole 32d and is able to move back and forth in the front-rear direction X, and the protruding portion 92 that protrudes from the operating body portion 91 in a direction intersecting the front-rear direction X is able to move back and forth in the front-rear direction X within the groove portion 32e. Therefore, while the entire operating section 90 can move back and forth in the front-rear direction X, the protruding ridge 92 is locked by the groove 32e around the axis in the front-rear direction X, preventing rotation and rattling around that axis, and eliminating the need to provide separate guides or rotation-stopping members.

[0060] Furthermore, in this embodiment, the operating section 90 is provided on the rear surface and not on the outer surface of the side wall 40. This reduces the number of parts for operation and suppresses structural complexity. In particular, if operating parts were provided on the side wall 40, a connection structure to the circuit board 51 and wiring would be necessary, but these can be omitted, resulting in a simpler configuration. Also, when a user touches the badge 1, they may grasp the side wall 40, but the absence of operating parts on the side wall 40 helps prevent accidental operation. The rear end of the operating section 90 is at the same position as the rear surface of the rear surface 30 in the front-rear direction X, or slightly recessed from the rear surface, which also helps prevent accidental operation of the operating section 90 provided on the rear surface 30.

[0061] Furthermore, in this embodiment, the structure for connecting the lid portion 35 to the rear body portion 31 is made of two claw members 35a on the lid portion 35 and two fitting holes 31a into which the claw members 35a correspond to each other. This improves the stability when the lid portion 35 is attached to the rear body portion 31 and also allows for a thinner claw member 35a itself.

[0062] Furthermore, without departing from the spirit of the present invention, it is possible to replace the components in the above-described embodiments with well-known components, and the above-described modifications may be combined as appropriate.

[0063] For example, in this embodiment, the housing 10 is composed of a circular front portion 20 and a rear portion 30 when viewed in the front-rear direction, and a cylindrical side wall portion 40 arranged between them, but it is not limited to this. For example, the side wall portion and the rear portion may be formed integrally in a hemispherical shape with respect to the circular front portion.

[0064] Furthermore, although the notch 51h of the substrate 51 is formed in a straight line extending in the vertical direction Z, it is not limited to this, and in Figure 5, it may be connected to the second peripheral edge 51e by extending from the first peripheral edge 51d inward into the housing 10, so that the first peripheral edge 51d and the notch, and the second peripheral edge 51e and the notch, are connected at an obtuse angle. Also, the notch 51h may be formed in a curved shape instead of a straight line. Alternatively, a structure may be provided in which the first peripheral edge 51d and the second peripheral edge 51e are directly connected without a notch. [Explanation of symbols]
