[0027] An example of an embodiment of an electronic device 10 according to the technique of the present disclosure will be described with reference to the accompanying drawings.

[0028] In the following description, for convenience of explanation, the width direction, front-rear direction, and height direction of the electronic device 10 are indicated by three arrows, X, Y, and Z. First, the height direction is indicated by arrow Z, and the direction indicated by arrow Z is the upward direction of the electronic device 10, and the opposite direction is the downward direction. The width direction is indicated by arrow X perpendicular to arrow Z, and the direction indicated by arrow X is the rightward direction of the electronic device 10, and the opposite direction is the leftward direction. The front-rear direction is indicated by arrow Y, which is perpendicular to arrows Z and X, and the direction indicated by arrow Y is the forward direction of the electronic device 10, and the opposite direction is the rearward direction. Furthermore, in the following description, expressions using sides, such as upper side, lower side, left side, right side, front side, and rear side, have the same meaning as expressions using directions.

[0029] First Embodiment As an example, as shown in FIG. 1, the electronic device 10 has, for example, a printer function. The electronic device 10 is, for example, a portable electronic device. The electronic device 10 is, for example, a mobile printer. For ease of explanation, the following embodiment will be described using a mobile printer 11 as an example. The electronic device 10 is an example of an "electronic device" according to the technology of the present disclosure.

[0030] The mobile printer 11 is capable of communicating with external devices. In the example shown in FIG. 1, the mobile printer 11 is capable of communicating with a smartphone 100. The communication method may be, for example, wireless communication (e.g., Bluetooth (registered trademark)), but wired communication may also be used. The mobile printer 11 receives image data IM sent from the smartphone 100 and prints the subject image represented by the received image data IM onto a film F. The film F is, for example, a film containing a photosensitive material (so-called instant film).

[0031] The mobile printer 11 includes an exterior body 12. In the example shown in FIG. 1, the exterior body 12 has a rectangular parallelepiped housing structure with its longitudinal direction in the X direction. The exterior body 12 houses electronic components and the like for realizing the printer function and other functions of the mobile printer 11. Furthermore, for example, the printed film F is discharged from an outlet 14 provided on the left side surface of the exterior body 12. The exterior body 12 is an example of an "exterior body" according to the technology of the present disclosure.

[0032] A display unit 16 is formed on the exterior body 12. The display unit 16 displays at least one of letters, symbols, and figures on the surface of the exterior body 12. In the example shown in FIG. 1, the display unit 16 is formed on the top surface 12A of the exterior body 12. In the example shown in FIG. 1, the display unit 16 displays the letters "ABCD." The content displayed by the display unit 16 may be, for example, a company name, a product name, a person's name, a catchphrase, a logo, and / or a pictogram. The content displayed by the display unit 16 may also be, for example, a symbol (for example, an arrow indicating the film ejection direction) or a figure (for example, a power button mark) for explaining the operation of the mobile printer 11. The display unit 16 is an example of a "display unit" according to the technology of the present disclosure.

[0033] 2, as an example, a linear striped pattern is formed on exterior body 12 along the longitudinal direction (here, the X direction). Specifically, a striped pattern consisting of periodic concaves and convexes is formed on the surface of exterior body 12. Below, the striped pattern will be described using upper surface 12A of the surfaces of exterior body 12 as an example, but it goes without saying that similar striped patterns may also be formed on other surfaces of exterior body 12.

[0034] When viewed in a cross section normal to the longitudinal direction (when viewed in a transverse cross section), protrusions 18 are formed periodically on top surface 12A of exterior body 12. When viewed in a transverse cross section, protrusions 18 have a triangular shape, and the vertices are continuous along the longitudinal direction, forming a linear striped pattern. In this way, the periodic presence of protrusions 18 forms a striped pattern consisting of periodic projections and recesses.

[0035] Here, display unit 16 displays at least one of letters, symbols, and figures by virtue of a difference in three-dimensional shape from its surroundings on the surface of exterior body 12. In the example shown in FIG. 2, display unit 16 is convex toward the outside (here, the upper side) of exterior body 12 relative to its surroundings. This results in a difference in three-dimensional shape from its surroundings. Specifically, in the striped pattern described above, the portion corresponding to display unit 16 is a protrusion 20 that is higher than the protrusions 18 present in the surroundings. That is, in the example shown in FIG. 2, the difference in three-dimensional shape is the difference in the height of the convex portions of the striped pattern.

[0036] The difference in three-dimensional shape between the display unit 16 and the other areas causes a difference in the way natural light (here, ambient light) is reflected. In this way, the difference in three-dimensional shape from the surroundings makes the display unit 16 visually recognizable (here, the letters ABCD appear to stand out).

[0037] As an example, as shown in FIG. 3 , the exterior body 12 is configured to include a first member 22 and a second member 24 disposed adjacent to the first member 22. The first member 22 is, for example, a cover member that forms the upper side of the exterior body 12, and the second member 24 is, for example, a cover member that forms the lower side of the exterior body 12. The mobile printer 11 is provided with a light-emitting unit 26 inside the exterior body 12. The light-emitting unit 26 is provided inside the exterior body 12 at a position facing the display unit 16. The light-emitting unit 26 is capable of transmitting light L through the exterior body 12 to the outside. The emitted light L is, for example, light having a wavelength in the visible light range. The light-emitting unit 26 is an example of a "light-emitting unit" according to the technology of the present disclosure.

[0038] In the example shown in FIG. 3 , the light-emitting unit 26 includes, for example, LED (Light Emitting Diode) light sources 26A-26C. The LED light sources 26A-26C are arranged linearly inside the exterior housing 12, starting from the right side. Here, an example in which three LED light sources 26A-26C are arranged has been described. However, this is merely an example, and two or fewer, or four or more, LED light sources may be arranged. The spacing, position, and arrangement of the LED light sources (e.g., arranged circumferentially or at the vertices of a square) may also be set appropriately. Each of the LED light sources 26A-26C includes an RGB light-emitting element, and the color and light intensity of the emitted light L can be changed by controlling the light-emitting mode of each light-emitting element. The LED light sources 26A-26C are an example of an “LED light source” according to the technology of the present disclosure.

[0039] 3, the light-emitting unit 26 is housed inside a first member 22 that constitutes an upper portion of the exterior body 12. The first member 22 has an abutting portion 23 that abuts against the second member 24. Specifically, the first member 22 has a bottom plate portion 22A that is a plate-shaped portion having a thickness in the height direction, and a side wall portion 22B that stands upright along the height direction from the periphery of the bottom plate portion 22A. Here, when the first member 22 and the second member 24 are combined, the side wall portion 22B stands upright toward the second member 24. As will be described in detail later, the side wall portion 22B abuts against the second member 24 and also functions as the abutting portion 23.

[0040] Light-emitting unit 26 is provided at a position facing the inner surface of bottom plate portion 22A. Emitted light L from light-emitting unit 26 passes through bottom plate portion 22A and is emitted to the outside of exterior body 12. Here, the transmission of emitted light L includes the emitted light L being scattered in exterior body 12 and being emitted to the outside. Here, because exterior body 12 is made of a resin material, the emitted light L is scattered when passing through bottom plate portion 22A, and the emission range of emitted light L to the outside is expanded.

[0041] Furthermore, a space 28 capable of accommodating a film F is formed in the second member 24 that constitutes the lower portion of the exterior body 12. The film F is accommodated inside the space 28 via a cover (not shown). Here, for convenience of explanation, a single film F is depicted, but it goes without saying that multiple films F may be accommodated in the space 28. The space 28 is openable to the lower surface of the exterior body 12. In other words, a light-emitting unit 26 is provided at a position facing a display unit 16 formed on the surface of the exterior body 12 opposite the side where the film F is accommodated (here, the upper surface). The second member 24 also has a shape similar to that of the first member 22.

[0042] 4, the transmissive portion 36, which is a region through which the emitted light L passes through the exterior body 12, is determined by the distance between the light-emitting portion 26 and the inner surface of the exterior body 12 and the spread angle of the emitted light L. Specifically, the transmissive portion 36 is determined by the distance between the LED light sources 26A to 26C of the light-emitting portion 26 and the inner surface 22A1 of the bottom plate portion 22A and the spread angle of the emitted light L from the LED light sources 26A to 26C. In other words, the first member 22 of the exterior body 12 has the transmissive portion 36 that transmits the emitted light L from the light-emitting portion 26. The transmissive portion 36 is an example of a "transmissive portion" according to the technology of the present disclosure.

[0043] In the mobile printer 11, the light-emitting unit 26 may be illuminated (e.g., lit or flashing). This can notify the user of the operating status of the mobile printer 11 and improve the user experience (e.g., increase the enjoyment the user feels when using the device). When the exterior body 12 of the mobile printer 11 is viewed in plan (here, from above), the light emitted by the light-emitting unit 26 overlaps the display unit 16 (i.e., the light-emitting unit 26 faces the display unit 16). In this case, the light emitted by the light-emitting unit 26 makes the display unit 16 difficult to see. In other words, when the light-emitting unit 26 emits light, the emitted light L that passes through the exterior body 12 becomes more visible, while the reflected light from the display unit 16 (e.g., reflected light due to differences in the three-dimensional shape of the display unit 16 from its surroundings) becomes less visible. As a result, the visibility of the display unit 16 decreases.

[0044] Therefore, as shown in FIG. 5 as an example, in this embodiment, a difference is made in the transmittance of light L emitted from the light-emitting unit 26 between a region of the exterior body 12 corresponding to the display unit 16 and the surrounding region. Specifically, a transmission suppressing layer 30 containing a material with lower light transmittance than the surrounding region is formed on the inner surface of the exterior body 12. More specifically, in the first member 22 of the exterior body 12, the transmission suppressing layer 30 is formed on the inner surface 22A1 of the bottom plate portion 22A. The transmission suppressing layer 30 is formed in the region corresponding to the display unit 16. The region corresponding to the display unit 16 is, for example, the back surface of the display unit 16 and has the same size as the display unit 16. In the example shown in FIG. 5, transmission suppressing layers 30A, 30B, 30C, and 30D are formed, each having a shape obtained by inverting the letters "ABCD" displayed on the display unit 16. The region corresponding to the display unit 16 does not have to be the same size as the display unit 16, and the size may be changed as appropriate.

[0045] The transmission suppression layers 30A, 30B, 30C, and 30D are formed on the inner surface 22A1 of the first member 22 by printing. Specifically, the transmission suppression layers 30A, 30B, 30C, and 30D are formed by printing using paint containing a material that absorbs wavelengths in the visible light range. For example, the transmission suppression layers 30A, 30B, 30C, and 30D are printed using black paint. A portion of the emitted light L is absorbed or reflected due to interaction with the transmission suppression layer 30. In this way, transmission of the emitted light L in the area corresponding to the display unit 16 is suppressed.

[0046] As described above, the light-emitting unit 26 is disposed at a position facing the display unit 16. Furthermore, a transmission suppressing layer 30 is formed inside the exterior body 12 in a region corresponding to the display unit 16. Therefore, the transmission of part of the emitted light L from the light-emitting unit 26 is suppressed by the transmission suppressing layer 30. Here, the black paint contained in the transmission suppressing layer 30 absorbs part of the emitted light L. Furthermore, in the example shown in FIG. 5 , when the first member 22 is viewed from the inside surface side (here, when viewed from below), the transmission suppressing layers 30A, 30B, 30C, and 30D have shapes that are each a reversed version of the letters "ABCD." Therefore, the emitted light L is suppressed from transmitting through the exterior body 12 in the regions that have the shapes that are each a reversed version of the letters "ABCD."

[0047] As an example, as shown in Fig. 6, in the mobile printer 11, when the light-emitting unit 26 emits light, as described above, the transmission of the emitted light L is suppressed by the transmission suppressing layer 30 provided in the area corresponding to the display unit 16. This makes it difficult for the emitted light L to transmit through the display unit 16, making it easier to view the display unit 16. In the example shown in Fig. 6, the transmission suppressing layer 30 has a shape in which each of the letters "ABCD" is reversed, making it easier to view the letters "ABCD" on the display unit 16.

[0048] This allows the area corresponding to display unit 16 to be distinguished from other areas due to differences in the degree of visual recognition, making it easy to recognize display unit 16 even when light-emitting unit 26 provided inside exterior body 12 is lit. Furthermore, within the area illuminated by emitted light L, the content displayed by transmission-suppressing layer 30 (here, the letters "ABCD") appears as a shadow, improving the design.

[0049] Incidentally, the portion of exterior body 12 facing light-emitting unit 26 is required to contain a material with relatively high transparency in order to transmit light L emitted from light-emitting unit 26. On the other hand, the portion opposite the portion facing light-emitting unit 26 is required to contain a material with relatively low transparency. This is to prevent unnecessary external light from entering the interior of exterior body 12.

[0050] When two types of components with different optical properties (e.g., optical transparency) are combined to form exterior body 12, the difference in optical properties makes it obvious that they are separate components at the contact point. As a result, exterior body 12 as a whole lacks unity, and the appearance may be impaired.

[0051] Therefore, as an example, as shown in FIG. 7 , the thickness of the coating film 32 is adjusted in the first member 22 of the exterior body 12. The first member 22 has the coating film 32 and a base 34. The coating film 32 is formed on the surface of the base 34. The base 34 is formed including a translucent material. Here, the translucent material is a material that transmits light while scattering it. The base 34 is, for example, a milky white resin. The coating film 32 is formed by adhering paint to the surface of the base 34, and the type of paint is appropriately selected depending on the color variation of the exterior body 12. As described above, the emitted light L from the light-emitting unit 26 is emitted to the outside through the first member 22. By forming the first member 22 from a translucent material, the emitted light L is more easily emitted to the outside of the exterior body 12, making the emitted light L more easily visible. The coating film 32 is an example of a “coating film” according to the technology disclosed herein.

[0052] The coating film 32 has a thickness t1 on the side wall portion 22B of the first member 22. On the other hand, the coating film 32 has a thickness t2 on the bottom plate portion 22A of the first member 22. The thickness t1 of the coating film 32 on the side wall portion 22B is thicker than the thickness t2 of the coating film 32 on the bottom plate portion 22A. In other words, in the transmission portion 36 (see FIG. 4) of the bottom plate portion 22A through which the emitted light L passes, the thickness t2 of the coating film 32 is thinner than the thickness t1 of the coating film 32 on the side wall portion 22B.

[0053] Specifically, the thickness t1 of the coating film 32 on the side wall portion 22B is 1.5 times or more the thickness t2 of the coating film 32 on the bottom plate portion 22A. More specifically, the thickness t1 is, for example, about 20 μm, and the thickness t2 is, for example, about 10 to 12 μm.

[0054] The second member 24 has a bottom plate portion 24A and a side wall portion 24B extending vertically from the periphery of the bottom plate portion 24A. The second member 24 is formed of a non-transparent material. Here, the non-transparent material is a material that blocks light. Specifically, the non-transparent material is, for example, a material in which titanium oxide particles are dispersed in a resin that serves as a base material. That is, the second member 24 is formed of, for example, a resin containing titanium oxide. As described above, the second member 24 has a space 28 formed therein in which the film F is housed. Because the second member 24 is formed of a non-transparent material, external light is prevented from entering the interior of the second member 24.

[0055] The first member 22 and the second member 24 are joined adjacent to each other. The first member 22 abuts against the second member 24 via the abutment portion 23. In the example shown in FIG. 7, the side wall portion 22B of the first member 22 abuts against the side wall portion 24B of the second member 24. That is, in the first member 22, the side wall portion 22B serves as the abutment portion 23. Specifically, the lower surface of the side wall portion 22B of the first member 22 and the upper surface of the side wall portion 24B of the second member 24 are in contact with each other. As described above, the thickness t1 of the coating film 32 on the side wall portion 22B is greater than the thickness t2 of the coating film 32 on the bottom plate portion 22A. That is, the thickness t1 of the coating film 32 on the abutment portion 23 is greater than the thickness t2 of the coating film 32 on the transmission portion 36.

[0056] The first member 22 and the second member 24 are joined together with the side wall portion 22B and the side wall portion 24B in contact with each other. The joining method of the first member 22 and the second member 24 is not particularly limited, and may be, for example, a mechanical fastening method that combines a fixing means in which fixing claws are fitted into holes with screws, or they may be joined together with an adhesive, ultrasonic welding, or the like.

[0057] 8, consider a case where the thickness t1 of the coating film 32 on the side wall portion 22B of the first member 22 (hereinafter simply referred to as coating film thickness t1) is thinner than the thickness t2 of the coating film 32 on the bottom plate portion 22A of the first member 22 (hereinafter simply referred to as coating film thickness t2). In this case, the difference in light transmittance between the first member 22 and the second member 24 at the contact portion (here, the side wall portion 22B and the side wall portion 24B) makes it clear that they are separate parts.

[0058] 8, consider a case where the coating thickness t1 of the side wall portion 22B of the first member 22 is thicker than the coating thickness t2 of the bottom plate portion 22A of the first member 22. In this case, the light transmittance of the side wall portion 22B of the first member 22 becomes closer to that of the side wall portion 24B of the second member 24, making the difference between the first member 22 and the second member 24 less noticeable. As a result, the overall appearance of the exterior body 12 becomes more unified, improving its appearance.

[0059] Next, the electrical hardware configuration of the mobile printer 11 according to this embodiment will be described. As an example, as shown in FIG. 9, the mobile printer 11 includes a control device 40. The control device 40 controls the overall operation of the mobile printer 11. The control device 40 includes a processor 42, storage 44, a RAM (Random Access Memory) 46, and an external I / F (interface) 48. The processor 42, RAM 46, storage 44, and external I / F 48 are connected to a bus 49. The processor 42 is an example of a "processor" according to the technology of the present disclosure. The control device 40 is an example of a "computer" according to the technology of the present disclosure.

[0060] A memory is connected to the processor 42. The memory includes a storage 44 and a RAM 46. The processor 42 has, for example, a CPU (Central Processing Unit). Note that the processor 42 may be provided with a GPU (Graphics Processing Unit) dedicated to image processing, separate from the CPU.

[0061] The RAM 46 is a memory that temporarily stores information and is used as a work memory by the processor 42. The RAM 46 may be, for example, a dynamic random access memory (DRAM) or a static random access memory (SRAM).

[0062] The storage 44 is a non-volatile storage device that stores various programs, various parameters, etc. Examples of the storage 44 include flash memory (e.g., an EEPROM (Electrically Erasable and Programmable Read Only Memory) and an SSD (Solid State Drive)) and / or an HDD (Hard Disk Drive). Note that the flash memory and HDD are merely examples, and at least one of a flash memory, an HDD, a magnetoresistive memory, and a ferroelectric memory may be used as the storage 44.

[0063] The external I / F 48 controls the exchange of various information with devices that exist outside the control device 40. The external I / F 48 is connected to the light emitting unit 26, the reception device 38, and the detection unit 50 so as to be able to communicate with them.

[0064] The light-emitting unit 26 is capable of emitting light L having various emission colors and emission intensities according to parameter settings. Specifically, as described above, the mobile printer 11 includes an LED light source 26A, an LED light source 26B, and an LED light source 26C as the light-emitting unit 26. The LED light source 26A is composed of an R (red) light-emitting element 27A, a G (green) light-emitting element 27B, and a B (blue) light-emitting element 27C. The light intensity and emission color of the LED light source 26A are adjusted by changing the parameter settings related to the light emission of each light-emitting element of the LED light source 26A.

[0065] Similarly, the LED light sources 26B and 26C are each composed of an R (red) light-emitting element 27A, a G (green) light-emitting element 27B, and a B (blue) light-emitting element 27C. In the following description, when there is no need to distinguish between the R (red) light-emitting element 27A, the G (green) light-emitting element 27B, and the B (blue) light-emitting element 27C, they may be simply referred to as "light-emitting element 27."

[0066] The light intensity and emitted color of the LED light sources 26B and 26C are also adjusted by changing the parameter settings of the light emitting element 27. As a result of adjusting the light intensity and emitted color of the LED light sources 26A to 26C, the light emitting unit 26 emits the emitted light L.

[0067] The light emitting element 27 is an LED that emits pulsed light in response to a drive pulse that is periodically input. Parameters of the light emitting element 27 include a light emission time determined by the duty ratio of the drive pulse and / or the number of repetitions of the drive pulse.

[0068] The detection unit 50 is capable of detecting information related to the exterior body 12 of the mobile printer 11. In the example shown in Fig. 9, an optical sensor 51 is shown as the detection unit 50. The optical sensor 51 is a sensor that can detect, for example, the color and illuminance of light incident on a light receiving element.

[0069] As described above, the light-emitting unit 26 can be made to emit light to notify the user of the operating status of the mobile printer 11 or to improve the user experience. In this case, the light L emitted from the light-emitting unit 26 is affected by the state of the exterior body 12. For example, suppose that white light is emitted from the light-emitting unit 26 when the exterior body 12 is red. In this case, even though the user intends to see white light, the emitted light L passes through the red exterior body 12 and is therefore perceived by the user as reddish. In this way, the state in which the user perceives the emitted light L changes from the intended state. Here, the state in which the user perceives the emitted light L includes the color of the emitted light L perceived by the user and the intensity (e.g., brightness) of the emitted light L perceived by the user.

[0070] In view of these circumstances, in the mobile printer 11 according to this embodiment, in the control device 40, the processor 42 reads the control program 44A from the storage 44 and executes the read control program 44A on the RAM 46. As a result, the processor 42 operates as an acquisition unit 42A and a light source control unit 42B. The control program 44A is an example of a "program" according to the technology of the present disclosure.

[0071] As an example, as shown in FIG. 10 , in the processor 42, the acquisition unit 42A acquires exterior body information 52 from the storage 44. The exterior body information 52 is information about the exterior body 12. The exterior body information 52 includes information about the exterior body 12 itself and information about the surroundings of the exterior body 12. The exterior body information 52 includes exterior body color information 54. The exterior body color information 54 is information about the color of the exterior body 12. The exterior body color information 54 is stored in the storage 44, for example, during the manufacturing stage of the mobile printer 11. Also, for example, the exterior body color information 54 may be obtained by the detection unit 50 detecting the color of the exterior body 12. Furthermore, when the exterior body 12 is replaced, the exterior body color information 54 may be updated by reading a non-contact storage medium (not shown) provided in the exterior body 12 with a non-contact reading device (not shown). Then, the acquisition unit 42A outputs the exterior body color information 54 to the light source control unit 42B. The exterior body information 52 is an example of "exterior body information" according to the technology of the present disclosure, and the exterior body color information 54 is an example of "exterior body color information" according to the technology of the present disclosure.

[0072] The light source control unit 42B executes control to adjust the light emission mode of the light-emitting unit 26 based on the exterior body information 52. Specifically, the light source control unit 42B acquires exterior body color information 54 from the acquisition unit 42A. The light source control unit 42B also executes control to adjust the light emission mode of the light-emitting unit 26 according to the color of the exterior body 12 indicated by the exterior body color information 54. Here, the control of the light emission mode includes control of the light emission color of the light-emitting unit 26 and control of the amount of light emitted by the light-emitting unit 26. The control of the light emission mode also includes control of whether the light-emitting unit 26 emits light (for example, lights up or blinks), or control of which of the multiple LED light sources 26A to 26C to emit light or in what order to emit light.

[0073] Specifically, light source control unit 42B executes control to set parameters. More specifically, light source control unit 42B acquires setting table 56 from storage 44. Setting table 56 is a table in which the color of exterior body 12 is used as input information and parameters of the light emission conditions of light-emitting unit 26 are used as output information. Setting table 56 is obtained, for example, in a sensory test using an actual device, by adjusting the emitted light color according to the color of exterior body 12 and setting light L transmitted through the exterior body as a reference color.

[0074] 10, when the input information in setting table 56 indicates red or blue as the color of exterior body 12, parameters of each of LED light sources 26A-26C are shown as corresponding output information. The parameters include the duty ratio (ratio of pulse width to pulse interval) of the drive pulse of each of light-emitting elements 27 of R (red), G (green), and B (blue) constituting each of LED light sources 26A-26C, and the total light-emitting time T of each of LED light sources 26A-26C. Although not shown, parameters for colors of exterior body 12 other than red and blue are also held in setting table 56.

[0075] The light source control unit 42B uses the setting table 56 to read out parameters of the LED light sources 26A-26C based on the exterior body color information 54. Specifically, it reads out parameters of the LED light sources 26A-26C that correspond to the color of the exterior body 12 indicated by the exterior body color information 54. The light source control unit 42B then sets the read-out parameters of the LED light sources 26A-26C. Specifically, it sets the duty ratios of the drive pulses of the R (red), G (green), and B (blue) light-emitting elements 27 that make up each of the LED light sources 26A-26C, and also sets the total light emission time T of each of the LED light sources 26A-26C. In this way, the light source control unit 42B executes control to adjust the light emission modes of the LED light sources 26A-26C.

[0076] Adjusting the duty ratio of the drive pulse of the light-emitting element 27 of each color means adjusting the light emission amount per unit time of the light-emitting element 27 of each color. By combining the light emission amounts of the light-emitting elements 27 of each color, it is possible to produce light of various colors as LED light sources 26A to 26C, which are a collection of light-emitting elements 27 of each color.

[0077] For example, if the light emission intensity of the R (red) light-emitting element 27 is relatively increased, the light of the LED light sources 26A-26C will become redder, and if the light emission intensity of the B (blue) light-emitting element 27 is relatively increased, the light of the LED light sources 26A-26C will become bluer. By equalizing the light emission intensity of each light-emitting element 27, the light of the LED light sources 26A-26C will become white light. Furthermore, by finely adjusting the light emission intensity of each color light-emitting element 27, it is possible to create light of a wider variety of colors. Furthermore, by making each of the LED light sources 26A-26C emit light of a different color, it is possible to change the color of each region of each LED light source 26A-26C. In this way, by adjusting the light intensity ratio of the light emitted by the R (red), G (green), and B (blue) light-emitting elements 27 in the LED light sources 26A-26C and changing the light emission color of each LED light source 26A-26C, it is possible to emit emitted light L according to the color of the exterior body 12.

[0078] For example, when the color of the exterior body 12 is red and it is desired to emit white light (i.e., when the intended emitted color is white), the light emission amount of the R (red) light-emitting element 27 is relatively reduced to make the color of the emitted light L transmitted through the exterior body 12 closer to white. Also, when the color of the exterior body 12 is blue and it is desired to emit white light (i.e., when the intended emitted color is white), the light emission amount of the B (blue) light-emitting element 27 is relatively reduced to make the color of the emitted light L transmitted through the exterior body 12 closer to white.

[0079] Note that, although an example in which parameters are set using setting table 56 has been given here, this is merely one example. Instead of setting table 56, parameters may be set using a parameter derivation formula (not shown) that expresses setting table 56 as a function. The parameter derivation formula is an arithmetic formula in which a value indicating the exterior body color is an independent variable and the value of the parameter is a dependent variable.

[0080] The light source control unit 42B determines whether the timing for the light emitting unit 26 to emit light has arrived. Examples of timing for the light emitting unit 26 to emit light include when the mobile printer 11 is running, when communicating with an external device, or when printing on the film F. If the timing for the light emitting unit 26 to emit light has arrived, the light source control unit 42B causes the LED light sources 26A to 26C to emit light. As described above, the light emission mode of each of the LED light sources 26A to 26C is adjusted according to the color of the exterior body 12. The light L emitted from the light emitting unit 26 passes through the exterior body 12. When the light L that has passed through the exterior body 12 is perceived by the user's eye E, the light L is perceived in a state close to the intended emitted color.

[0081] Next, the light emission control process in the mobile printer 11 according to this embodiment will be described with reference to Fig. 11. Fig. 11 is a flowchart showing an example of the light emission control process. The flow of the light emission control process shown in Fig. 11 is an example of a "control method" according to the technology of the present disclosure.

[0082] 11 as an example, first, in step ST12, the acquisition unit 42A acquires exterior body information 52 from the storage 44. The exterior body information 52 includes exterior body color information 54. After the processing of step ST12 is executed, the light emission control processing proceeds to step ST14.

[0083] In step ST14, the light source control unit 42B controls the light emission mode of the light-emitting unit 26 in accordance with the exterior body information 52 acquired in step ST12. Specifically, the light source control unit 42B acquires the setting table 56 from the storage 44, and sets parameters for each of the LED light sources 26A to 26C using the acquired setting table 56. After the processing of step ST14 is executed, the light emission control processing proceeds to step ST16.

[0084] In step ST16, the light source control unit 42B determines whether or not the light emission timing of the light emitting unit 26 has arrived. If the light emission timing has arrived in step ST16, the determination is affirmative, and the light emission control process proceeds to step ST18. If the light emission timing has not arrived in step ST16, the determination is negative, and the light emission control process proceeds to step ST16 again.

[0085] In step ST18, the light source control unit 42B causes the light emitting unit 26 to emit light. After the process of step ST18 is executed, the light emission control process proceeds to step ST20.

[0086] In step ST20, the light source control unit 42B determines whether or not a condition for terminating the light emission control process (hereinafter referred to as the "termination condition") has been satisfied. One example of the termination condition is that an instruction to terminate the light emission control process has been accepted by the acceptance device 38. In step ST22, if the termination condition has not been satisfied, the determination is negative, and the light emission control process proceeds to step ST12. In step ST20, if the termination condition has been satisfied, the determination is positive, and the light source control process terminates.

[0087] As described above, the electronic device 10 according to the first embodiment includes the exterior body 12 and the light-emitting unit 26. The light-emitting unit 26 is provided inside the exterior body 12. The light-emitting unit 26 is capable of emitting light L to the outside by collapsing the exterior body 12. The electronic device 10 also includes a processor 42, in which an acquisition unit 42A acquires exterior body information 52. The light source control unit 42B executes control to adjust the light emission mode of the light-emitting unit 26 based on the acquired exterior body information 52. This adjusts the light emission mode of the light-emitting unit 26 depending on the state of the exterior body 12. This makes it easier to bring the visible state of the light L transmitted through the exterior body 12 closer to a pre-designed state, compared to a case where the light emission mode is always the same even when the state of the exterior body 12 changes.

[0088] Furthermore, in electronic device 10 according to the first embodiment, exterior body information 52 includes exterior body color information 54, which is information about the color of exterior body 12. Control executed by light source control unit 42B includes control to adjust the emitted color of light-emitting unit 26 based on exterior body color information 54. This adjusts the emitted color of light-emitting unit 26 according to the color of exterior body 12, making it easier to bring the perceived color of light L transmitted through exterior body 12 closer to a pre-intended state, compared to a case where the emitted color is always the same even when the color of exterior body 12 changes.

[0089] Furthermore, in electronic device 10 according to the first embodiment, a striped pattern consisting of periodic projections and recesses is formed on the surface of exterior body 12, and the differences in the three-dimensional shape of display unit 16 are the differences in height of the protruding portions of the striped pattern. When a striped pattern is formed on the surface of exterior body 12 to enhance design, display unit 16 is formed by the differences in height of the three-dimensional shape. In this case, emitted light L is more likely to transmit through the valleys of the projections and recesses of the striped pattern, but in this configuration, the light emission mode of light-emitting unit 26 can be adjusted, making it easier to recognize light L that has transmitted through exterior body 12.

[0090] Furthermore, in the electronic device 10 according to the first embodiment, a display unit 16 is formed on the exterior body 12. The display unit 16 displays at least one of letters, symbols, and figures by using a three-dimensional shape that differs from its surroundings on the surface of the exterior body 12. The display unit 16 is also provided in a position facing the light-emitting unit 26. When the display unit 16 displays letters or the like by using a three-dimensional shape that differs, differences in the transmittance of light L in the exterior body 12 are likely to occur. In this configuration, the light emission mode of the light-emitting unit 26 can be adjusted, making it easier to recognize the light L that has passed through the exterior body 12.

[0091] Furthermore, in the electronic device 10 according to the first embodiment, the exterior body 12 has a coating film 32 formed on the outside, and the thickness t1 of the coating film 32 in the transmission portion 36 through which light from the light-emitting portion 26 passes is set to be thinner than the thickness t2 of the coating film 32 in other regions. Even if the thickness t2 of the coating film 32 is made thinner to facilitate the transmission of light L emitted from the light-emitting portion 26, this configuration makes it easier to recognize the light L that has passed through the exterior body 12.

[0092] Furthermore, in the electronic device 10 according to the first embodiment, the light-emitting unit 26 includes LED light sources 26A to 26C, and the control by the light source control unit 42B includes control for adjusting the light emission modes of the LED light sources 26A to 26C. This allows the light emission mode to be adjusted by adjusting the light emission time determined by the duty ratio of the LED drive pulse and the number of repetitions of the drive pulse, making it easy to adjust the light emission mode of the LED light sources 26A to 26C.

[0093] (First Modification) In the first embodiment described above, an example was given in which the light-emitting mode of the light-emitting unit 26 was adjusted in accordance with the exterior body color information 54, but the technology of the present disclosure is not limited to this. In this first modified example, the light-emitting mode of the light-emitting unit 26 is adjusted in accordance with the transmitted light color information 58 and the transmitted light intensity information 60.

[0094] 12, in the processor 42, the acquisition unit 42A acquires the exterior body information 52 from the storage 44. In this first modified example, the exterior body information 52 includes transmitted light color information 58 and transmitted light intensity information 60. The transmitted light color information 58 is information relating to a change in the color of the light L transmitted through the exterior body 12. Specifically, the transmitted light color information 58 is information that can identify the degree of change in the color of the light L transmitted through the exterior body 12 relative to the color of the light L emitted from the light-emitting unit 26 (hereinafter also simply referred to as the "color change rate").

[0095] Furthermore, the transmitted light intensity information 60 is information relating to changes in the intensity of the light L transmitted through the exterior body 12. Specifically, the transmitted light intensity information 60 is information that can identify the degree of change (hereinafter simply referred to as the "intensity change rate") in the intensity (e.g., luminance) of the light L transmitted through the exterior body 12 relative to the light L emitted from the light-emitting unit 26. The color change rate and the intensity change rate are affected by, for example, the material of the exterior body 12, the type of paint, the thickness of the coating film 32, and the surface shape of the exterior body 12. The transmitted light color information 58 is an example of "transmitted light color information" according to the technology of the present disclosure, and the transmitted light intensity information 60 is an example of "transmitted light intensity information" according to the technology of the present disclosure.

[0096] The transmitted light color information 58 and the transmitted light intensity information 60 are stored in the storage 44, for example, during the manufacturing stage of the mobile printer 11. The transmitted light color information 58 and the transmitted light intensity information 60 are obtained, for example, by measuring the color and brightness of transmitted light using a color luminance meter in a test using an actual device and determining the rate of change relative to the intended emitted color and brightness. The acquisition unit 42A then outputs the transmitted light color information 58 and the transmitted light intensity information 60 to the light source control unit 42B.

[0097] The light source control unit 42B acquires transmitted light color information 58 and transmitted light intensity information 60 from the acquisition unit 42A. Furthermore, the light source control unit 42B executes control to adjust the light emission mode of the light emitting unit 26 in accordance with the color change rate indicated by the transmitted light color information 58 and the intensity change rate indicated by the transmitted light intensity information 60.

[0098] Specifically, the light source control unit 42B executes control to set parameters. More specifically, the light source control unit 42B acquires the light emission mode derivation formula 62 from the storage 44. The light emission mode derivation formula 62 is an arithmetic expression in which the color change rate and the intensity change rate are independent variables and the values ​​of parameters (e.g., the duty ratio of the drive pulse and the total light emission time T) are dependent variables. The light emission mode derivation formula 62 is obtained, for example, by adjusting the light emission color and light emission amount according to the measurement results of transmitted light in a sensory test using an actual device, to match the light emission color and brightness to the intended light emission color and brightness.

[0099] For example, when the color change rate of the exterior body 12 tends to decrease the red component, and when it is desired to emit white light (i.e., when the intended emitted color is white), the light emission amount of the R (red) light emitting element 27 is relatively increased to bring the color of the emitted light L transmitted through the exterior body 12 closer to white. Also, for example, when the intensity change rate of the exterior body 12 tends to decrease the intensity of the light L by about 10%, the light emission amount of each light emitting element 27 is increased by about 10% to bring the luminance of the emitted light L transmitted through the exterior body 12 closer to the intended value.

[0100] Although the light emission mode derivation formula 62 is used to set the parameters, this is merely an example, and a derivation table may also be used. The derivation table is a table that uses the color change rate and intensity change rate as input information and the parameter values ​​as output information.

[0101] When the light emission timing of the light-emitting unit 26 arrives, the light source control unit 42B causes the LED light sources 26A to 26C to emit light. As described above, the light emission mode of each of the LED light sources 26A to 26C is adjusted according to the color change rate and the intensity change rate. When the light L transmitted through the exterior body 12 is perceived by the user's eye E, the light L is perceived in a state close to the intended light emission mode.

[0102] As described above, in the electronic device 10 according to the first modification, the exterior body information 52 includes transmitted light color information 58. The control by the light source control unit 42B includes control for adjusting the emitted color of the light-emitting unit 26 based on the transmitted light color information 58. This adjusts the emitted color according to the color change rate of the light L transmitted through the exterior body 12, allowing the color of the light L transmitted through the exterior body 12 to be closer to the intended color than when the emitted color is always the same. For example, if the exterior body 12 has color variations, and the appearance of the color of the light L changes depending on the color of the exterior body 12, it would be necessary to provide a different description of the color of the light L for each color variation. This configuration allows the color of the light L transmitted through the exterior body 12 to be closer to the intended color, reducing the complexity of the description. Furthermore, this reduces the variation in the appearance of the emitted color of the product, contributing to improved quality.

[0103] Furthermore, in electronic device 10 according to the first modification, package information 52 includes transmitted light intensity information 60. Control by light source control unit 42B includes control to adjust the amount of light emitted by light-emitting unit 26 based on transmitted light intensity information 60. This adjusts the amount of light emitted in accordance with the rate of change in the intensity of light L transmitted through package 12, making it possible to bring light L transmitted through package 12 closer to the intended light intensity (e.g., luminance) compared to when the amount of light emitted is always the same.

[0104] Although the first modified example has been described with reference to an example in which the light-emitting mode of the light-emitting unit 26 is adjusted based on both the transmitted light color information 58 and the transmitted light intensity information 60, the technology of the present disclosure is not limited to this. For example, the embodiment may be such that only the emitted color of the light-emitting unit 26 is adjusted based on the transmitted light color information 58, or such that only the amount of light emitted by the light-emitting unit 26 is adjusted based on the transmitted light intensity information 60.

[0105] Second Embodiment In the first embodiment, an example in which the light emission mode is adjusted in accordance with the exterior body information 52 has been described, but the technology of the present disclosure is not limited to this. In the second embodiment, the light emission mode of the light-emitting unit 26 is adjusted based on ambient light information 64.

[0106] As an example, as shown in FIG. 13 , the mobile printer 11 includes a light sensor 51. The light sensor 51 detects ambient light (i.e., external light) around the exterior body 12 via a light receiving element. The light sensor 51 then outputs ambient light information 64 to the processor 42 based on the detection result. The ambient light information 64 is information related to the ambient light around the exterior body 12. The ambient light information 64 is an example of "ambient light information" according to the technology of the present disclosure. The ambient light information 64 includes ambient light color information 66 and ambient light intensity information 68. The ambient light color information 66 is information indicating the color of the ambient light. The ambient light intensity information 68 is information indicating the brightness around the exterior body 12 (i.e., the illuminance of the ambient light).

[0107] In the processor 42, the acquisition unit 42A acquires ambient light color information 66 and ambient light intensity information 68 as ambient light information 64 from the light sensor 51. Then, the acquisition unit 42A outputs the ambient light color information 66 and the ambient light intensity information 68 to the light source control unit 42B.

[0108] The light source control unit 42B acquires ambient light color information 66 and ambient light intensity information 68 from the acquisition unit 42A. The light source control unit 42B executes control to adjust the light emission mode of the light-emitting unit 26 based on the ambient light information 64. Specifically, the light source control unit 42B executes control to adjust the light emission mode of the light-emitting unit 26 in accordance with the color of the ambient light indicated by the ambient light color information 66 and the surrounding brightness indicated by the ambient light intensity information 68.

[0109] Specifically, the light source control unit 42B executes control to set parameters. More specifically, the light source control unit 42B acquires a light emission mode derivation formula 70 from the storage 44. The light emission mode derivation formula 70 is an arithmetic expression that uses the color and illuminance of ambient light as independent variables and the values ​​of parameters (e.g., the duty ratio of the drive pulse and the total light emission time T) as dependent variables. The light emission mode derivation formula 70 is obtained, for example, by adjusting the light emission color and light emission amount according to the measurement results of ambient light in a sensory test using an actual device.

[0110] For example, when the red component of the color of the ambient light exceeds a threshold (for example, indoors under red lighting or outdoors under the setting sun), and white light is to be emitted (i.e., the intended emitted color is white), the light emission amount of the R (red) light-emitting element 27 is relatively increased. This makes it possible to make the color of the emitted light L transmitted through the exterior body 12 closer to white, even in reddish ambient light. Also, for example, when the brightness of the ambient light exceeds a threshold, the light emission amount of each light-emitting element 27 is increased, thereby making the light amount of the emitted light L transmitted through the exterior body 12 closer to the intended value. This makes it easier to see the light emitted by the light-emitting unit 26, even in a dazzling environment such as sunlight.

[0111] Although the light emission mode derivation formula 70 is used to set the parameters, this is merely an example, and a derivation table may also be used. The derivation table is a table that takes the color and brightness of the ambient light as input information and the parameter values ​​as output information.

[0112] When the light emission timing of the light-emitting unit 26 arrives, the light source control unit 42B causes the LED light sources 26A to 26C to emit light. As described above, the light emission mode of each of the LED light sources 26A to 26C is adjusted according to the color and brightness of the ambient light. When the light L transmitted through the exterior body 12 is perceived by the user's eye E, the light L is perceived in a state close to the intended light emission mode.

[0113] As described above, in the electronic device 10 according to the second embodiment, the acquisition unit 42A in the processor 42 acquires ambient light information 64, which is information about the ambient light around the exterior body. The control by the light source control unit 42B includes control to adjust the light emission mode of the light-emitting unit 26 based on the acquired ambient light information 64. This adjusts the light emission mode according to the ambient light around the exterior body 12, so that light L transmitted through the exterior body 12 can be made closer to the intended recognition state compared to when the light emission mode is always the same even when the ambient light changes.

[0114] Furthermore, in electronic device 10 according to the second embodiment, ambient light information 64 includes ambient light intensity information 68. Control by light source control unit 42B includes control to adjust the amount of light emitted by light-emitting unit 26 based on ambient light intensity information 68. This adjusts the amount of light emitted according to the brightness around exterior body 12, so that light L transmitted through exterior body 12 can be made closer to the intended luminance, compared to when the amount of light emitted is always the same even when the brightness of the ambient light changes.

[0115] Furthermore, in electronic device 10 according to the second embodiment, ambient light information 64 includes ambient light color information 66. Control by light source control unit 42B includes control to adjust the emitted color of light-emitting unit 26 based on ambient light color information 66. This adjusts the emitted color to match the color of the ambient light around exterior body 12, making it possible to make light L transmitted through exterior body 12 closer to the intended emitted color compared to when the emitted color is always the same even when the color of the ambient light changes.

[0116] Note that, in the second embodiment, an example has been described in which the light-emitting mode of the light-emitting unit 26 is adjusted based on both the ambient light color information 66 and the ambient light intensity information 68, but the technology of the present disclosure is not limited to this. For example, an embodiment may be such that only the emission color of the light-emitting unit 26 is adjusted based on the ambient light color information 66, or an embodiment may be such that only the amount of light emitted by the light-emitting unit 26 is adjusted based on the ambient light intensity information 68.

[0117] <Third embodiment> In the first embodiment described above, an example was described in which exterior body color information 54 was used as exterior body information 52 and the light emission mode was adjusted based on the exterior body color information 54, but the technology of the present disclosure is not limited to this. In the third embodiment, the exterior body information 52 includes information related to the movable part 72 of the exterior body 12.

[0118] As an example, as shown in Fig. 14, the exterior body 12 includes a movable part 72. The movable part 72 forms part of the exterior body 12 and is movable relative to the main body of the exterior body 12. In the example shown in Fig. 14, the movable part 72 is a cover member 72A provided at a position facing the light-emitting unit 26. The cover member 72A can be opened and closed freely, and when the cover member 72A is in an open state, the light-emitting unit 26 is exposed to the outside of the exterior body 12. The cover member 72A is, for example, a slide cover.

[0119] The mobile printer 11 also includes a contact sensor 74. The contact sensor 74 detects the position of the movable part 72. In the example shown in FIG. 14, the contact sensor 74 detects whether the cover member 72A is in the open position. The contact sensor 74 is, for example, a mechanical switch that is turned on when the cover member 72A is in the open position and turned off when the cover member 72A is in the closed position. The contact sensor 74 outputs information about the movable part 72 based on the detection result as the exterior body information 52. That is, in this embodiment, the exterior body information 52 includes information about the movable part 72. In the example shown in FIG. 14, the contact sensor 74 outputs cover open / close information 76 to the processor 42. The cover open / close information 76 is information indicating the open / close state of the cover member 72A. The cover open / close information 76 is an example of "information about the state of the movable part of the exterior body" according to the technology of the present disclosure. The cover member 72A is an example of a "cover member" according to the technology of the present disclosure.

[0120] In the processor 42, the acquisition unit 42A acquires cover opening / closing information 76 as information relating to the movable unit 72 from the contact sensor 74. Then, the acquisition unit 42A outputs the cover opening / closing information 76 to the light source control unit 42B.

[0121] The light source control unit 42B acquires cover open / close information 76 from the acquisition unit 42A. The light source control unit 42B also executes control to adjust the light emission mode of the light emitter 26 according to the open / close state of the cover member 72A indicated by the cover open / close information 76. Specifically, the light source control unit 42B executes control to set parameters using a setting table 78. The mode of parameter control is the same as in the first embodiment described above, and therefore details will be omitted. Also, while an example in which parameters are set using the setting table 78 has been given here, this is merely an example, and it goes without saying that a light emission mode derivation formula may also be used.

[0122] For example, when the cover member 72A is open, the amount of light emitted by the light-emitting element 27 is relatively reduced. This allows the amount of emitted light L to approach an intended value even when the emitted light L is directly visible to the user.

[0123] When the light emission timing of the light-emitting unit 26 arrives, the light source control unit 42B causes the LED light sources 26A to 26C to emit light. As described above, the light intensity of each of the LED light sources 26A to 26C is adjusted depending on whether the cover member 72A is open or closed. Therefore, when the light L is perceived by the user's eye E, the light L is perceived in a state close to the intended light intensity.

[0124] As described above, in electronic device 10 according to the third embodiment, exterior body information 52 includes information about the state of movable part 72 of exterior body 12. Control by light source control unit 42B includes control to adjust the light emission mode of light-emitting unit 26 based on the information about the state of movable part 72. As a result, the light emission mode is adjusted according to the state of movable part 72 of exterior body 12, and light L emitted from light-emitting unit 26 can be made closer to the intended recognition state compared to when the light emission mode is always the same even when the state of movable part 72 changes.

[0125] Furthermore, in electronic device 10 according to the third embodiment, movable unit 72 is cover member 72A provided in a position facing light-emitting unit 26 on exterior body 12. Control by light source control unit 42B includes control to adjust the amount of light emitted by light-emitting unit 26 depending on whether cover member 72A is open or closed. This adjusts the amount of light emitted in accordance with whether cover member 72A of exterior body 12 is open or closed, making it possible to bring light L emitted from light-emitting unit 26 closer to the intended luminance compared to when the amount of light emitted is always the same regardless of whether cover member 72A is open or closed.

[0126] In the third embodiment, the cover member 72A is used as the movable portion 72, but the technology of the present disclosure is not limited to this. For example, the movable portion 72 may be a switch member or the like.

[0127] <Fourth embodiment> In the first embodiment described above, an example was described in which exterior body color information 54 was used as exterior body information 52 and the light emission mode was adjusted based on the exterior body color information 54, but the technology of the present disclosure is not limited to this. In the fourth embodiment, exterior body information 52 includes orientation information 82 that is information indicating the orientation of the electronic device 10.

[0128] As an example, as shown in FIG. 15 , the mobile printer 11 includes an attitude sensor 80. The attitude sensor 80 detects the attitude of the mobile printer 11. The attitude sensor 80 is, for example, an inertial sensor and an acceleration sensor. The attitude sensor 80 outputs attitude information 82 as the exterior body information 52. That is, in this embodiment, the exterior body information 52 includes the attitude information 82. The attitude information 82 is information indicating the attitude of the electronic device 10 (here, the mobile printer 11). The attitude of the electronic device 10 includes rotation angles about central axes in the front-to-back, left-to-right, and up-to-down directions from a reference position where the state of the electronic device 10 is placed on a horizontal surface. The attitude of the electronic device 10 also includes the movement speed of the electronic device 10 in each of the front-to-back, left-to-right, and up-to-down directions. The attitude information 82 is an example of “attitude information” according to the technology of the present disclosure.

[0129] In the processor 42, the acquisition unit 42A acquires the orientation information 82 from the orientation sensor 80. Then, the acquisition unit 42A outputs the orientation information 82 to the light source control unit 42B.

[0130] The light source control unit 42B acquires the attitude information 82 from the acquisition unit 42A. The light source control unit 42B also executes control to adjust the light emission mode of the light emitting unit 26 according to the attitude of the mobile printer 11 indicated by the attitude information 82.

[0131] Specifically, the light source control unit 42B executes control to set parameters. More specifically, the light source control unit 42B acquires a light emission mode derivation formula 84 from the storage 44. The light emission mode derivation formula 84 is an arithmetic expression in which a value indicating the attitude of the electronic device 10 (e.g., a rotation angle on the X, Y, and Z axes) is an independent variable, and the values ​​of parameters (e.g., a duty ratio of a drive pulse and a total light emission time T) are dependent variables. The light emission mode derivation formula 84 is obtained, for example, by adjusting the light emission color and light emission amount according to the attitude of the electronic device 10 in a sensory test using an actual device. Note that, although an example in which parameters are set using the light emission mode derivation formula 84 has been given here, this is merely an example, and it goes without saying that a derivation table may also be used.

[0132] For example, if the electronic device 10 is turned upside down, the light emission by the light-emitting unit 26 is stopped. This makes it easier for the user to recognize that the orientation of the electronic device 10 is different from the intended orientation. Also, for example, if the electronic device 10 is tilted, the light emission intensity of the LED light sources 26A to 26C is changed in sequence in accordance with the tilt of the light-emitting unit 26 (for example, the light emission intensity decreases as the tilt decreases). This makes it possible to visually present the movement of the electronic device 10 by the light emission of the light-emitting unit 26, which is entertaining to the user and improves the user experience.

[0133] As described above, in the electronic device 10 according to the fourth embodiment, the exterior body information 52 includes posture information 82 that indicates the posture of the electronic device 10. The control by the light source control unit 42B includes control to adjust the light emission mode of the light-emitting unit 26 based on the posture information 82. This adjusts the light emission mode in accordance with the posture of the electronic device 10, thereby improving the user experience compared to when the light emission mode is always the same regardless of changes in posture.

[0134] Furthermore, it goes without saying that the techniques disclosed in the above-described embodiments and the first modified example may be implemented in appropriate combinations.

[0135] (Second Modification) In the second modified example, in addition to the exterior body information 52 of each of the above embodiments, the exterior body information 52 includes operation status information 86 that indicates the operation status of the electronic device 10.

[0136] As an example, as shown in FIG. 16 , assume that the user presses the power button 19 with a finger F1. In this case, operating state information 86 is output from the power button 19 to the processor 42. Here, the operating state information 86 is information indicating that the power of the electronic device 10 (here, the mobile printer 11) has been turned on. In this embodiment, the exterior body information 52 includes the operating state information 86. In the processor 42, the acquisition unit 42A acquires the operating state information 86 of the mobile printer 11. Then, the acquisition unit 42A outputs the operating state information 86 to the light source control unit 42B. The operating state information 86 is an example of the “operating state information” according to the technology of the present disclosure.

[0137] The light source control unit 42B acquires the operating state information 86 from the acquisition unit 42A. The light source control unit 42B also executes control to adjust the light emission mode of the light-emitting unit 26 according to the operating state of the mobile printer 11 indicated by the operating state information 86. Specifically, the light source control unit 42B executes control to set parameters using a light emission mode derivation formula 88. The mode of parameter control is the same as in the fourth embodiment described above, and therefore details will be omitted. Note that, although an example in which parameters are set using the light emission mode derivation formula 88 has been given here, this is merely an example, and it goes without saying that a derivation table may also be used.

[0138] For example, when the power is turned on, the light-emitting unit 26 emits white light until the startup of the electronic device 10 is completed. This makes it easier for the user to visually recognize that the electronic device 10 is starting up. Furthermore, by visually representing the startup of the electronic device 10 by the light-emitting unit 26 emitting light, it is possible to provide an interesting feeling to the user, thereby improving the user experience.

[0139] As described above, in the electronic device 10 according to the second modification, the exterior body information 52 includes operating state information 86 that indicates the operating state of the electronic device 10. The control by the light source control unit 42B includes control to adjust the light emission mode of the light-emitting unit 26 based on the operating state information 86. This adjusts the light emission mode according to the operating state of the electronic device 10, thereby improving the user experience compared to when the light emission mode is always the same even when the operating state changes.

[0140] Although the second modified example has been described with reference to an example in which the power is ON as the operating state of the electronic device 10, the technology of the present disclosure is not limited thereto. For example, if the electronic device 10 has a battery, the operating state of the electronic device 10 may include the remaining battery charge. In this case, the remaining battery charge may be indicated by the light emitted by the light-emitting unit 26. For example, if the remaining battery charge is equal to or less than a threshold, the light-emitting unit 26 may emit red light. Furthermore, if the electronic device 10 has a printer function, the operating state of the electronic device 10 may include the progress of the printing function. In this case, the multiple LED light sources 26A-26C may be sequentially lit along the ejection direction while the printed film F is being ejected. Furthermore, the operating state of the electronic device 10 may include the communication state of the electronic device 10. In this case, the communication speed of the electronic device 10 may be indicated by the amount of light emitted by the light-emitting unit 26.

[0141] In the above-described embodiments, the display unit 16 is provided on the upper surface 12A of the exterior body 12, but the technology of the present disclosure is not limited to this. The display unit 16 may be provided on another surface of the exterior body 12. Furthermore, a plurality of display units 16 may be provided on the surface of the exterior body 12.

[0142] Although the above-described embodiments have been described with reference to exemplary embodiments in which the transmission suppressing layer 30 is formed by printing, the technology of the present disclosure is not limited thereto. The transmission suppressing layer 30 may be formed by attaching a sealing member (not shown). Specifically, in the first member 22 of the exterior body 12, a sealing member is attached to the inner surface 22A1 of the bottom plate portion 22A. The sealing member has, for example, a laminated structure and includes an adhesive layer, the transmission suppressing layer 30, and a coating layer. The sealing member is attached to the exterior body 12 via the adhesive layer. The transmission suppressing layer 30 corresponding to the content displayed on the display unit 16 is formed on the adhesive layer. The transmission suppressing layer 30 contains a material that absorbs wavelengths in the visible light range. The transmission suppressing layer 30 is protected by the coating layer. By attaching the sealing member, the transmission suppressing layer 30 is formed in the region corresponding to the display unit 16. This results in a difference in transmittance of the emitted light L emitted from the light-emitting unit 26 between the region corresponding to the display unit 16 and the surrounding region. As a result, the permeation suppressing layer 30 can be formed by simply attaching a sealing member, which can contribute to reducing the manufacturing costs of the electronic device 10.

[0143] In addition, in the above-described embodiments, the three-dimensional shape of the display unit 16 is described as being convex relative to the surrounding area, but the technology of the present disclosure is not limited to this. For example, the three-dimensional shape of the display unit 16 may be concave relative to the surrounding area, or the surrounding area may be roughened and the display unit 16 may have a smooth surface.

[0144] In addition, in the above-described embodiments, the transmission suppression layer 30 is formed by printing, but the technology of the present disclosure is not limited to this. For example, the transmission suppression layer 30 may be formed by partially molding a resin that is difficult for light to transmit, or by attaching a light-blocking cover that is a separate part from the exterior body 12 to the inside.

[0145] Furthermore, in the above-described embodiments, an example in which transmission of the emitted light L is suppressed in the region corresponding to the display unit 16 has been described, but the technology of the present disclosure is not limited to this. For example, a mode in which transmission of the emitted light L is promoted in the region corresponding to the display unit 16 may also be adopted. Specifically, the transmission of light in the region corresponding to the display unit 16 may be promoted by forming a transmission suppressing layer 30 in a portion other than the region corresponding to the display unit 16. In this way, a difference in light transmittance is created between the region corresponding to the display unit 16 and the surrounding area.

[0146] In addition, in each of the above embodiments, an example in which a striped pattern having periodic irregularities is formed on the surface of the exterior body 12 has been described, but the technology of the present disclosure is not limited to this. The surface of the exterior body 12 may have a structure other than a striped pattern that enhances the design, or may be a smooth surface.

[0147] In addition, in the above-described embodiments, the first member 22 and the second member 24 have symmetrical shapes when viewed in cross section, but the technology of the present disclosure is not limited to this. For example, the first member 22 may have a side wall portion 22B, and the second member 24 may be a plate-shaped member. In this case, the end face of the side wall portion 22B abuts against the periphery of the second member 24.

[0148] In addition, in each of the above embodiments, the exterior body 12 has been described as having a rectangular parallelepiped shape, but the technology of the present disclosure is not limited to this. For example, the exterior body 12 may have a square shape, a spherical shape, or a cylindrical shape.

[0149] In addition, in the above-described embodiments, the electronic device 10 is described as a mobile printer 11, but the technology of the present disclosure is not limited to this. The electronic device 10 may be, for example, a portable electronic device such as an instant camera, a digital camera, a smartphone, a tablet device, a notebook computer, or a mobile battery. The electronic device 10 may also be a stationary electronic device such as a desktop computer, a printer, a television, or a display.

[0150] In addition, in the above embodiments, the film F is a so-called instant film containing a photosensitive material, but the technology of the present disclosure is not limited to this. For example, photographic paper containing a heat-sensitive material may be used instead of the film F.

[0151] In addition, in each of the above embodiments, the light-emitting unit 26 is configured with an LED light source, but the technology of the present disclosure is not limited to this. For example, the light-emitting unit 26 may be configured with an organic EL (Electro-Luminescence) light-emitting element.

[0152] In addition, in each of the above-described embodiments, the coating film 32 is thickened on the entire side wall portion 22B, but the technology of the present disclosure is not limited to this. The coating film 32 may be thickened on the half of the side wall portion 22B facing the second member 24.

[0153] In addition, in the above-described embodiments, the coating film 32 is thinned overall on the bottom plate portion 22A, but the technology of the present disclosure is not limited to this. The coating film 32 may be thinned in an elliptical region including the transmission portion 36, or may be thinned only in the region corresponding to the transmission portion 36.

[0154] In addition, in the above-described embodiments, the base 34 of the first member 22 is made of a translucent material, but the technology of the present disclosure is not limited to this. For example, the base 34 may be made of a transparent material. However, as described above, it is preferable that the base 34 be made of a translucent material, as this makes it easier to adjust the appearance using the coating film 32.

[0155] Furthermore, in the above-described embodiments, the second member 24 is described as being made of a non-transparent resin, but the technology of the present disclosure is not limited to this. For example, the second member 24 may also be configured with a coating film (e.g., a coating film containing titanium oxide) formed on a substrate made of a translucent material. However, as described above, it is preferable that the second member 24 be made of a non-transparent material in order to prevent external light from entering.

[0156] Furthermore, in the above-described embodiments, an example in which the control program 44A is stored in the storage 44 has been described, but the technology of the present disclosure is not limited to this. For example, the control program 44A may be stored in a storage medium (not shown) such as an SSD or a USB (Universal Serial Bus) memory. The storage medium is a portable, computer-readable, non-transitory storage medium. The control program 44A stored in the storage medium is installed in the electronic device 10. The processor 42 executes a light emission control process in accordance with the control program 44A.

[0157] Furthermore, the control program 44A may be stored in a storage device such as another computer or server connected to the electronic device 10 via a network, and the control program 44A may be downloaded and installed in the electronic device 10 in response to a request from the electronic device 10. In other words, the program described in this embodiment (i.e., the program product) may be provided on a recording medium or may be distributed from an external computer.

[0158] In addition, in each of the above embodiments, the processor 42, storage 44, and RAM 46 of the electronic device 10 are exemplified as a computer, but the technology of the present disclosure is not limited to this, and devices including an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), and / or a PLD (Programmable Logic Device) may be applied instead of a computer. Furthermore, a combination of a hardware configuration and a software configuration may be used instead of a computer.

[0159] The hardware resources for executing the light emission control processes described in the above embodiments can be various processors, as listed below. Examples of processors include a CPU, which is a general-purpose processor that functions as a hardware resource for executing processes by executing software, i.e., a program. Examples of processors include dedicated electronic circuits, such as FPGAs, PLDs, or ASICs, which are processors with circuit configurations designed specifically for executing specific processes. Each processor has built-in or connected memory, and executes processes using the memory.

[0160] The hardware resource that executes the light emission control process may be configured with one of these various processors, or may be configured with a combination of two or more processors of the same or different types (for example, a combination of multiple FPGAs, or a combination of a CPU and an FPGA). Also, the hardware resource that executes the light emission control process may be a single processor.

[0161] As an example of configuring a system using a single processor, first, one processor is configured by combining one or more CPUs and software, and this processor functions as a hardware resource that executes the light emission control process. Second, there is a form in which a processor is used that realizes the functions of the entire system, including multiple hardware resources that execute the light emission control process, on a single IC (Integrated Circuit) chip, as typified by SoC (System-on-a-chip). In this way, the light emission control process is realized using one or more of the above-mentioned various processors as hardware resources.

[0162] More specifically, the hardware structure of these various processors can be an electronic circuit that combines circuit elements such as semiconductor devices. The above process is merely an example. It goes without saying that unnecessary steps may be deleted, new steps may be added, or the order of processing may be rearranged, without departing from the spirit of the invention.

[0163] The above-described description and illustrations are a detailed explanation of the parts related to the technology of the present disclosure and are merely an example of the technology of the present disclosure. For example, the above description of the configuration, functions, actions, and effects is an explanation of an example of the configuration, functions, actions, and effects of the parts related to the technology of the present disclosure. Therefore, it goes without saying that unnecessary parts may be deleted, new elements may be added, or replacements may be made to the above-described description and illustrations within the scope of the gist of the technology of the present disclosure. Furthermore, to avoid confusion and facilitate understanding of the parts related to the technology of the present disclosure, the above-described description and illustrations omit explanations of common technical knowledge that do not require particular explanation to enable the implementation of the technology of the present disclosure.

[0164] In this specification, "A and / or B" is synonymous with "at least one of A and B." In other words, "A and / or B" means that it may be only A, only B, or a combination of A and B. Furthermore, in this specification, the same concept as "A and / or B" is also applied when three or more things are expressed connected by "and / or."
