[0022] Next, the implementation manners will be described with reference to the accompanying drawings.

[0023] Hereinafter, the accompanying drawings used are for ease of explanation. It should be noted that the embodiments described below do not unduly limit the content recited in the claims. In addition, not all of the structures described below are essential components.

[0024] In addition, for ease of explanation, the names of the constituent parts are sometimes labeled with numbers such as first and second. However, this numbering is for facilitating the designation of each constituent part.

[0025] The electrical structure of the mobile printer 1 will be described.

[0026] Figure 1 is a diagram showing the electrical structure of the mobile printer 1. The mobile printer 1 in the present embodiment is a so-called thermal printer that heats the surface of thermal paper as a recording medium by a thermal head having a plurality of heating elements, thereby printing desired characters, images, etc. on the recording medium. In addition, in Figure 1 , in addition to the mobile printer 1 of the present embodiment, as an external device that supplies driving power from the outside of the mobile printer 1, a commercial power supply 2, a first power supply circuit 3, and a power transmission unit 4 are also illustrated.

[0027] Here, in the present embodiment, a case where the mobile printer 1 is a thermal printer having a thermal head as a print head is shown. However, as another example, the mobile printer 1 may be an inkjet printer having an inkjet head as a print head.

[0028] The commercial power supply 2 generates a power supply voltage signal Vac that is an AC voltage of a commercial frequency, and supplies it to the first power supply circuit 3 and the power transmission unit 4, respectively.

[0029] The first power supply circuit 3 converts the supplied power supply voltage signal Vac into a first DC voltage signal Vdc1 having a specified voltage value, and supplies it to the mobile printer 1. That is, driving power corresponding to the first DC voltage signal Vdc1 is supplied to the mobile printer 1. Such a first power supply circuit 3 is configured to include a converter circuit such as a flyback circuit, for example.

[0030] The power transmission unit 4 includes a power transmission circuit 5 and a power transmission coil 6. The power transmission circuit 5 converts the frequency of the power supply voltage signal Vac supplied from the first power supply circuit 3 into a high-frequency voltage signal of 100 kHz to 250 kHz, and outputs the converted voltage signal as a power transmission signal Vpt to the power transmission coil 6. Such a power transmission circuit 5 is configured to include, for example, a converter circuit that converts the power supply voltage signal Vac into a DC voltage, and an inverter circuit that converts the DC voltage into the high-frequency power transmission signal Vpt. The power transmission coil 6 outputs a magnetic field Pmg corresponding to the input power transmission signal Vpt. In addition, by the mobile printer 1 receiving this magnetic field Pmg, driving power corresponding to the magnetic field Pmg is supplied to the mobile printer 1.

[0031] That is, drive power corresponding to the first DC voltage signal Vdc1 output from the first power supply circuit 3 provided outside and drive power corresponding to the magnetic field Pmg output from the power transmission unit 4 can be supplied to the mobile printer 1 of the present embodiment. In addition, the mobile printer 1 is driven by the drive power corresponding to the first DC voltage signal Vdc1 or the drive power corresponding to the magnetic field Pmg. It should be noted that Figure 1 illustrates a case where drive power is supplied based on both the first DC voltage signal Vdc1 output from the first power supply circuit 3 and the magnetic field Pmg output from the power transmission unit 4. However, drive power can also be supplied to the mobile printer 1 based on only one of the first DC voltage signal Vdc1 output from the first power supply circuit 3 and the magnetic field Pmg output from the power transmission unit 4. Moreover, the structure can be as follows: in addition to the first DC voltage signal Vdc1 output from the first power supply circuit 3 and the magnetic field Pmg output from the power transmission unit 4, drive power is also supplied to the mobile printer 1 by a different method.

[0032] As Figure 1 shown, the mobile printer 1 includes a power supply unit 10, a control unit 20, a print head 30, a conveyance unit 40, and a cutting unit 50.

[0033] The power supply unit 10 includes a first connector CN1, a second connector CN2, a power receiving module 11, a power supply switching circuit 12, a battery module 13, and a second power supply circuit 14.

[0034] The first DC voltage signal Vdc1 output from the first power supply circuit 3 is supplied to the mobile printer 1 via the first connector CN1. The first DC voltage signal Vdc1 is input to the power supply switching circuit 12. As the first connector CN1 to which the first DC voltage signal Vdc1 is supplied in this way, a USB-Type-C socket connector having a shape that can mount a cable conforming to the USB-Type-C standard is used. That is, the power supply unit 10 includes a first connector CN1, which is a USB-Type-C socket connector to which the first DC voltage signal Vdc1 based on the power supply voltage signal Vac is supplied.

[0035] Here, in the first connector CN1 that is a USB-Type-C socket connector, in addition to the first DC voltage signal Vdc1, a communication signal for performing communication conforming to the USB (Universal Serial Bus) standard between the mobile printer 1 and an external device can also be input. In this case, the mobile printer 1 can also include a USB communication driver for controlling communication conforming to the USB standard.

[0036] Moreover, the first DC voltage signal Vdc1 input to the first connector CN1, which is a USB-Type-C socket connector, can also be a voltage signal compliant with the USB-PD (USB-Power Delivery) standard that can supply driving power of about 15W. In other words, the first connector CN1, which is a USB-Type-C socket connector, can input a voltage signal corresponding to the USB-PD standard, and can also input power of about 15W. In this case, the mobile printer 1 can also include a USB-PD driver for controlling the power supply compliant with the USB-PD standard.

[0037] The power receiving module 11 receives the magnetic field Pmg output by the power transmitting unit 4. In addition, the power receiving module 11 generates a second DC voltage signal Vdc2 corresponding to the magnetic field Pmg and outputs it to the power supply switching circuit 12. Specifically, the power receiving module 11 includes a power receiving coil 110 and a power receiving circuit 120. The power receiving coil 110 generates a high-frequency power receiving signal Vpr corresponding to the magnetic field Pmg by being supplied with the magnetic field Pmg, and outputs it to the power receiving circuit 120. The power receiving circuit 120 rectifies and smoothes the supplied high-frequency power receiving signal Vpr, and by controlling the voltage value, converts it into a second DC voltage signal Vdc2 with a specified voltage value and supplies it to the power supply switching circuit 12. That is, the power receiving module 11 includes a power receiving coil 110 that receives the power transmission signal Vpt based on the power supply voltage signal Vac as the power receiving signal Vpr in a non-contact manner, and a power receiving circuit 120 that converts the power receiving signal Vpr received by the power receiving coil 110 into the second DC voltage signal Vdc2, and receives the signal based on the power supply voltage signal Vac from the outside of the mobile printer 1 through non-contact power supply. Thus, the power output by the power transmitting unit 4 is transmitted to the mobile printer 1 in a non-contact manner. Here, the power receiving circuit 120 can also perform at least any one of rectification, smoothing, and voltage value control of the power receiving signal Vpr, and can also perform all of rectification, smoothing, and voltage value control.

[0038] In this way, in the present embodiment, non-contact power supply is performed from the power transmission coil 6 to the power receiving coil 110. In addition, the power generated in the power receiving coil 110 can be transmitted to the battery module 13.

[0039] Here, from the perspective of portability, the mobile printer 1 is required to be small and lightweight. Therefore, in the mobile printer 1, from the perspective of realizing contactless power reception in a small, lightweight, and low-cost manner, it is preferably implemented by electromagnetic induction. Specifically, a contactless power supply method that conforms to the wireless power supply standard Qi standard and can supply power of about 15 W is preferred. In other words, the power receiving module 11 of the mobile printer 1 preferably corresponds to the wireless power supply standard Qi standard and can receive power of about 15 W. Thus, contactless power supply to the mobile printer 1 can be performed without compromising the portability of the mobile printer 1. It should be noted that contactless power supply is sometimes referred to as wireless power supply, wireless charging, wireless transmission method, etc.

[0040] A first DC voltage signal Vdc1 supplied via the first connector CN1 and a second DC voltage signal Vdc2 output from the power receiving circuit 120 are input to the power supply switching circuit 12. The power supply switching circuit 12 outputs one of the first DC voltage signal Vdc1 and the second DC voltage signal Vdc2 as a power supply DC voltage signal Vch to the battery module 13 via the second connector CN2. Such a power supply switching circuit 12 can be constituted by a wired "OR" circuit, for example.

[0041] That is, when only the first DC voltage signal Vdc1 is input to the power supply switching circuit 12, the power supply switching circuit 12 outputs the first DC voltage signal Vdc1 as the power supply DC voltage signal Vch to the battery module 13. When only the second DC voltage signal Vdc2 is input to the power supply switching circuit 12, the power supply switching circuit 12 outputs the second DC voltage signal Vdc2 as the power supply DC voltage signal Vch to the battery module 13. When the first DC voltage signal Vdc1 and the second DC voltage signal Vdc2 are input to the power supply switching circuit 12, the power supply switching circuit 12 selects only one of the first DC voltage signal Vdc1 and the second DC voltage signal Vdc2, or combines the first DC voltage signal Vdc1 and the second DC voltage signal Vdc2, and outputs it as the power supply DC voltage signal Vch to the battery module 13.

[0042] The battery module 13 holds charges corresponding to the power supply DC voltage signal Vch based on at least one of the first DC voltage signal Vdc1 and the second DC voltage signal Vdc2, and outputs a battery DC voltage signal Vbat corresponding to the held charge amount from the second connector CN2 to the second power supply circuit 14.

[0043] Here, in the mobile printer 1 in the present embodiment, as Figure 1As shown, the power supply DC voltage signal Vch output by the power supply switching circuit 12 is input to the battery module 13, and the battery module 13 outputs the battery DC voltage signal Vbat based on the input power supply DC voltage signal Vch to the second power supply circuit 14. That is, the voltage signal output by the power supply switching circuit 12 is input to the second power supply circuit 14 via the battery module 13. Thus, the battery module 13 functions as a stabilization circuit that reduces the possibility of fluctuations in the voltage value of the voltage signal supplied to the second power supply circuit 14, and the operation of the second power supply circuit 14 is stable. As such a battery module 13, for example, a lithium-ion secondary battery can be used.

[0044] The second power supply circuit 14 generates a drive voltage signal Vd with a specified voltage value by boosting or bucking the voltage value of the supplied battery DC voltage signal Vbat, and outputs it to the control unit 20. Here, in Figure 1 it is shown that the second power supply circuit 14 generates one drive voltage signal Vd and outputs it to the control unit 20. However, the second power supply circuit 14 may also generate a plurality of drive voltage signals Vd corresponding to the operating voltages of the structures of the control units 20 to which the drive voltage signal Vd is supplied, and output them to the corresponding structures of the control units 20.

[0045] It should be noted that the electrical structure of the power supply unit 10 is not limited to Figure 1 the structure shown. For example, it may also be that the power supply switching circuit 12 that inputs the first DC voltage signal Vdc1 and the second DC voltage signal Vdc2 infers the amount of charge stored in the battery module 13 by detecting the voltage value of the battery DC voltage signal Vbat output by the battery module 13. When it is determined that sufficient charge is stored in the battery module 13, the supplied first DC voltage signal Vdc1 and second DC voltage signal Vdc2 are output to the second power supply circuit 14 without passing through the battery module 13. When it is determined that sufficient charge is not stored in the battery module 13, the supplied first DC voltage signal Vdc1 and second DC voltage signal Vdc2 are output to both the battery module 13 and the second power supply circuit 14, thereby concurrently charging the battery module 13 and supplying a voltage signal to the second power supply circuit 14. Moreover, when neither the first DC voltage signal Vdc1 nor the second DC voltage signal Vdc2 is supplied to the power supply switching circuit 12, the power supply switching circuit 12 may also output the battery DC voltage signal Vbat output by the battery module 13 to the second power supply circuit 14.

[0046] That is, the power supply switching circuit 12 can also switch the voltage signal supplied to the second power supply circuit 14 to the first DC voltage signal Vdc1, or to the second DC voltage signal Vdc2, or to the battery DC voltage signal Vbat, according to the amount of charge stored in the battery module 13 and the presence or absence of supply of the first DC voltage signal Vdc1 and the second DC voltage signal Vdc2.

[0047] The control unit 20 includes a control circuit 21, a non-volatile memory 22, a reception buffer 23, a print head drive control unit 24, a recording paper conveyance control unit 25, and a recording paper cutting control unit 26.

[0048] The control circuit 21 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and other peripheral circuits (not shown). The drive voltage signal Vd output from the power supply unit 10 and print data (not shown) including image information formed on the recording medium are input to the control circuit 21. Further, the control circuit 21 drives using the drive voltage signal Vd as an operation voltage, and controls each unit of the mobile printer 1 including the non-volatile memory 22, the reception buffer 23, the print head drive control unit 24, the recording paper conveyance control unit 25, and the recording paper cutting control unit 26, based on the print data.

[0049] The non-volatile memory 22 includes semiconductor storage elements such as an EEPROM (Electrically Erasable Programmable Read-Only Memory) or a flash memory, and a storage medium such as a hard disk. In the non-volatile memory 22, various data can be rewritten and stored under the control of the control circuit 21.

[0050] The reception buffer 23 includes a temporary storage area such as a RAM, and is formed of, for example, a semiconductor storage device. In the reception buffer 23, various information such as instructions related to printing, such as print data, is stored under the control of the control circuit 21.

[0051] In the print head drive control unit 24, a first control signal Ctr1 generated by the input control circuit 21 based on print data and a drive voltage signal Vd output by the power supply unit 10 are input. In addition, at a timing specified by the first control signal Ctr1, the print head drive control unit 24 generates a head drive signal Sdr based on the drive voltage signal Vd and outputs it to the print head 30. That is, the drive voltage signal Vd output by the power supply unit 10 is supplied to the print head 30 via the control unit 20. In other words, the power supply unit 10 supplies the drive voltage signal Vd to the print head 30 via the control unit 20. The print head 30 includes a plurality of resistors 32 arranged along a direction orthogonal to the transport direction of the recording medium. By supplying the head drive signal Sdr output by the print head drive control unit 24 to each of the plurality of resistors 32, the resistors 32 generate heat.

[0052] In the recording paper transport control unit 25, a second control signal Ctr2 generated by the input control circuit 21 based on print data and a drive voltage signal Vd output by the power supply unit 10 are input. In addition, at a timing specified by the second control signal Ctr2, the recording paper transport control unit 25 generates a medium transport signal Str based on the drive voltage signal Vd and outputs it to the transport unit 40. That is, the drive voltage signal Vd output by the power supply unit 10 is supplied to the transport unit 40 via the control unit 20. In other words, the power supply unit 10 supplies the drive voltage signal Vd to the transport unit 40 via the control unit 20. The transport unit 40 includes a transport motor 42 for transporting the recording medium in the transport direction. By supplying the medium transport signal Str output by the recording paper transport control unit 25 to the transport motor 42, the transport motor 42 is driven, and along with the drive of the transport motor 42, the recording medium is transported along the specified transport direction.

[0053] In the recording paper cutting control unit 26, a third control signal Ctr3 generated by the input control circuit 21 based on print data and a drive voltage signal Vd output by the power supply unit 10. At the timing specified by the third control signal Ctr3, the recording paper cutting control unit 26 generates a medium cutting signal Sct based on the drive voltage signal Vd and outputs it to the cutting unit 50. That is, the drive voltage signal Vd output by the power supply unit 10 is supplied to the cutting unit 50 via the control unit 20. In other words, the power supply unit 10 supplies the drive voltage signal Vd to the cutting unit 50 via the control unit 20. The cutting unit 50 includes a cutting motor 52 for cutting the recording medium at a specified timing. The medium cutting signal Sct output by the recording paper cutting control unit 26 is supplied to the cutting motor 52, so that the cutting motor 52 is driven. Along with the driving of the cutting motor 52, a movable blade 56 described later is driven in a manner of sliding toward a fixed blade 54 described later. Thereby, the recording medium is pressed against the fixed blade 54, and the recording medium is cut to a specified size.

[0054] Here, in the present embodiment, Figure 1 shows a mechanical part including a print head 30, a conveyance unit 40, and a cutting unit 50 as a mechanical unit UN1.

[0055] In addition, the mechanical unit UN1 may also include, for example, a gear train connected to the conveyance motor 42, or one or more of the print head 30, etc.

[0056] It should be noted that the structure of the mechanical unit UN1 is not necessarily limited to this example. For example, it may also include the conveyance motor 42 and have other structures.

[0057] In addition, the structure of the control unit 20 is not necessarily limited to this example. The control unit 20 may, for example, also include a wiring board for controlling the conveyance motor 42 and the print head 30, and may also include terminals such as USB terminals that can be connected to external devices.

[0058] It should be noted that this wiring board may also be referred to as a control board, etc.

[0059] In the mobile printer 1 configured as described above, based on the drive voltage signal Vd output by the power supply unit 10, the control circuit 21 starts to operate. In addition, the control circuit 21 generates a first control signal Ctr1, a second control signal Ctr2, and a third control signal Ctr3 based on the input print data and outputs them to the print head drive control unit 24, the recording paper conveyance control unit 25, and the recording paper cutting control unit 26.

[0060] Accordingly, the recording medium is conveyed along the conveyance direction, and in synchronization with the conveyance of the recording medium, the resistor 32 generates heat. As a result, a desired position on the recording medium is heated, and desired characters, images, etc. are formed on the recording medium. In addition, the recording medium on which characters, images, etc. are formed is cut to a specified size. Accordingly, the recording medium of the specified size on which desired characters, images, etc. are formed is discharged from the mobile printer 1.

[0061] As described above, the mobile printer 1 of the present embodiment includes: a print head 30 that prints on a recording medium; a conveyance unit 40 that conveys the recording medium to the print head 30; a cutting unit 50 that cuts the recording medium; a control unit 20 that controls the operations of the print head 30, the conveyance unit 40, and the cutting unit 50; and a power supply unit 10 that supplies a drive voltage signal Vd to the print head 30, the conveyance unit 40, and the cutting unit 50. In addition, through the control of the control unit 20, the conveyance unit 40 conveys the recording medium to the print head 30, and the print head 30 supplies heat to the conveyed recording medium. As a result, a desired image is formed on the recording medium that is thermal paper. After that, the recording medium on which the image is formed is cut to a desired size by the cutting unit 50. As a result, the recording medium of the desired size on which the image is formed is discharged from the mobile printer 1.

[0062] The configuration of the mobile printer 1 will be described.

[0063] Then, the configuration of the mobile printer 1 will be described.

[0064] Figure 2 It is a perspective view of the mobile printer 1 when the cover 312 is closed.

[0065] Figure 3 It is a perspective view of the mobile printer 1 when the cover 312 is open.

[0066] Here, in the following description, the X direction, the Y direction, and the Z direction that are orthogonal to each other are used. In addition, in the following description, sometimes the starting point side of the arrow indicating the X direction in the drawing is referred to as the -X side, the front end side is referred to as the +X side, the starting point side of the arrow indicating the Y direction in the drawing is referred to as the -Y side, the front end side is referred to as the +Y side, the starting point side of the arrow indicating the Z direction in the drawing is referred to as the -Z side, and the front end side is referred to as the +Z side.

[0067] As Figure 2 and Figure 3As shown, the mobile printer 1 has a housing 100. The housing 100 includes: a first surface 101 and a second surface 102 that are disposed opposite to each other in the direction along the Z-axis; a third surface 103 and a fourth surface 104 that are disposed opposite to each other in the direction along the Y-axis; and a fifth surface 105 and a sixth surface 106 that are disposed opposite to each other in the direction along the X-axis. Specifically, in the housing 100, the first surface 101 and the second surface 102 are disposed opposite to each other such that the first surface 101 is on the -Z side and the second surface 102 is on the +Z side in the direction along the Z-axis, the third surface 103 and the fourth surface 104 are disposed opposite to each other such that the third surface 103 is on the -Y side and the fourth surface 104 is on the +Y side in the direction along the Y-axis, and the fifth surface 105 and the sixth surface 106 are disposed opposite to each other such that the fifth surface 105 is on the +X side and the sixth surface 106 is on the -X side in the direction along the X-axis. Thus, the first surface 101, the second surface 102, the third surface 103, the fourth surface 104, the fifth surface 105, and the sixth surface 106 form a receiving space for accommodating various structures inside the housing 100. In addition, the first surface 101 is provided so as to be rotatable about the end on the +X side as a rotation axis. Thus, a part of the receiving space formed by the first surface 101, the second surface 102, the third surface 103, the fourth surface 104, the fifth surface 105, and the sixth surface 106 can be opened and closed. Here, in the following description, the receiving space formed by the first surface 101, the second surface 102, the third surface 103, the fourth surface 104, the fifth surface 105, and the sixth surface 106 is sometimes referred to as the receiving space of the housing 100.

[0068] As Figure 3 shown, a roll paper R is accommodated in the receiving space of the housing 100. The roll paper R is a so-called roll paper formed by winding the aforementioned recording medium, and in the present embodiment, it is a thermal roll paper formed by winding a thermal paper as the recording medium. Here, in the following description, the recording medium constituting the roll paper R is sometimes referred to as the recording paper P.

[0069] It should be noted that the roll paper R can also be referred to as a winding body or the like, for example.

[0070] In addition, as Figure 3As shown, a paper pressing roller 48 and a gear 46 are provided at the -X side end of the first surface 101. The paper pressing roller 48 includes a rotating shaft along the Y direction and is arranged to be rotatable. The gear 46 is fixed to the +Y side end of the paper pressing roller 48. When the first surface 101 closes the accommodation space of the housing 100, the paper pressing roller 48 and the gear 46 configured as described above are accommodated in this accommodation space. At this time, the gear 46 passes through the opening 44 of the housing 100 and contacts the conveying motor 42 accommodated in the accommodation space of the housing 100. Thus, when the conveying motor 42 is driven by the medium conveying signal Str output by the control unit 20, this driving force is transmitted to the paper pressing roller 48 via the gear 46, and the paper pressing roller 48 is driven.

[0071] In addition, as Figure 2 and Figure 3 shown, the operation unit UI is located on the sixth surface 106 of the housing 100. The operation unit UI functions as a user interface for receiving the operation information of the user. In addition, by the user operating the operation unit UI, the mobile printer 1 performs a prescribed action including a printing process.

[0072] It should be noted that the user can also be referred to as a customer, etc.

[0073] In addition, the first connector CN1, which is set to be at least partially exposed outside the housing 100, is located on the third surface 103 of the housing 100. As described above, the first connector CN1 is a USB-Type-C socket connector, and supplies the first DC voltage signal Vdc1 as driving power to the mobile printer 1. In addition, when USB communication conforming to the USB communication standard of USB-Type-C can be performed with the first connector CN1, the mobile printer 1 is communicably connected to an external device such as a host computer via the first connector CN1. Thus, in addition to the operation of the above-described operation unit UI, the user can also cause the mobile printer 1 to perform a prescribed action including a printing process by operating an external device communicably connected via the first connector CN1.

[0074] Here, in the present embodiment, the housing 100 is composed of a housing 311 and a cover 312.

[0075] In addition, in the mobile printer 1, a detachable belt clip 313 is provided on the second surface 102 of the housing 311.

[0076] The belt clip 313 has a mounting portion that can be detachably mounted on a prescribed portion of the user or the user's clothes, etc. This prescribed portion can also be, for example, a belt, or clothes such as pants other than the belt.

[0077] As for the structure for detachably fixing the second surface 102 of the housing 311 and the belt clip 313, there is no particular limitation. For example, as a structure that can be easily detached and attached without using tools, a structure using a magnetic connector, a snap member, etc. can also be used. The magnetic connector utilizes magnetism, and the snap member uses an insertion utilizing the elasticity of resin, etc. As the magnetic connector, for example, a combination in which magnets are provided on both sides of the housing 311 and the belt clip 313 can also be used, or a combination in which a magnet is provided on one side of the housing 311 and the belt clip 313 and a metal is provided on the other side can also be used.

[0078] It should be noted that the housing 311 and the belt clip 313 can also be fixedly connected in a non-detachable manner, for example, by screw fastening that requires tools.

[0079] Here, there is no particular limitation on the position where the belt clip 313 is arranged relative to the housing 311, and various positions can also be adopted.

[0080] In the present embodiment, in the X direction, the operation unit UI is arranged on one side of the housing 311, and the belt clip 313 is arranged on the same side as the operation unit UI. The operation unit UI can also be, for example, an operation panel operated by the user.

[0081] It should be noted that as another example, in the case where the operation unit UI is arranged on the fourth surface 104 of the cover 312, the belt clip 313 can also be arranged on the other side in the X direction.

[0082] Here, the mobile printer 1 according to the present embodiment is a printing device driven by a battery such as a battery pack, and is assumed to be used in various scenarios.

[0083] For example, it is assumed that the user temporarily takes the mobile printer 1 outside a store, etc., or uses it outdoors for most of the time, etc. In this case, it is desired that the user uses the mobile printer 1 hands-free, and a scenario where the mobile printer 1 is mounted on the user's belt, etc. is assumed.

[0084] Then, an example of the internal structure of the mobile printer 1 will be described.

[0085] Figure 4A It is a cross-sectional view showing an example of the internal structure of the mobile printer 1. In Figure 4A It shows the same XYZ as Figure 2 and Figure 3 the same.

[0086] As Figure 4AAs shown, in the accommodation space of the housing 100, there are accommodated a first wiring board 80, a paper pressing roller 48, a print head 30, a cutting motor 52, a fixed blade 54, a movable blade 56, a power receiving module 11, and a roll paper accommodation section 60.

[0087] It should be noted that the roll paper accommodation section 60 may also be referred to as a winding body accommodation section or the like, for example.

[0088] In addition, regarding the wiring connected to the power receiving coil 110 of the power receiving module 11, the illustration is omitted in Figure 4A and will be described using Figure 4B for explanation.

[0089] The first wiring board 80 is located in the region on the +X side of the accommodation space of the housing 100 and is near the fifth surface 105 of the housing 100. Various circuits and electronic components including the power supply switching circuit 12 included in the aforementioned power supply unit 10, the second power supply circuit 14, the control circuit 21 included in the control unit 20, the non-volatile memory 22, the reception buffer 23, the print head drive control section 24, the recording paper conveyance control section 25, and the recording paper cutting control section 26 are provided on the first wiring board 80. That is, the control unit 20 is provided on the first wiring board 80. It should be noted that in the present embodiment, the case where the first wiring board 80 is constituted by one board is described, but the first wiring board 80 may also be configured to include a plurality of boards.

[0090] The paper pressing roller 48, the print head 30, the cutting motor 52, the fixed blade 54, and the movable blade 56 are located in the region on the -X side of the accommodation space of the housing 100 and are near the sixth surface 106 of the housing 100.

[0091] Specifically, the paper pressing roller 48 is located at the -X side end of the first surface 101 and is arranged such that the rotation axis is substantially parallel to the Y direction. In addition, the print head 30 is provided on the -X side of the paper pressing roller 48 so as to face the paper pressing roller 48. Further, the recording paper P wound as a roll paper R is clamped by the paper pressing roller 48 and the print head 30 which are arranged to face each other.

[0092] Here, as described above, the paper pressing roller 48 is driven along with the driving of the conveying motor 42. Therefore, the recording paper P clamped by the paper pressing roller 48 and the print head 30 is conveyed in a manner of being pulled out from the roll paper R along with the driving of the paper pressing roller 48. In addition, the recording paper P pulled out from the roll paper R is discharged to the outside of the mobile printer 1 from the discharge port 160 located on the +Z side of the housing 100. That is, the conveying motor 42, the gear 46, and the paper pressing roller 48 pull out the recording paper P from the roll paper R and convey the recording paper P to the discharge port 160 via the print head 30. The structure including the conveying motor 42, the gear 46, and the paper pressing roller 48 corresponds to the aforementioned conveying unit 40. In other words, the conveying unit 40 pulls out the recording paper P from the roll paper R and conveys the recording paper P to the print head 30.

[0093] The fixed blade 54 and the movable blade 56 are arranged on the upstream side of the paper pressing roller 48 and the print head 30 and on the downstream side of the discharge port 160 along the conveying direction of the recording paper P. At this time, the conveying path of the recording paper P is located between the fixed blade 54 and the movable blade 56. Specifically, the fixed blade 54 and the movable blade 56 are located on the +Z side of the paper pressing roller 48 and the print head 30 and on the -Z side of the discharge port 160. At this time, the fixed blade 54 is located on the +X side of the conveying path of the recording paper P, and the movable blade 56 is located on the -X side of the conveying path of the recording paper P.

[0094] In the present embodiment, the conveying path of the recording paper P is set from the time point when the recording paper P passes through the print head 30 to the time point when it exits from the discharge port 160.

[0095] In addition, the cutting motor 52 is located near the movable blade 56. The cutting motor 52 is driven by being supplied with the medium cutting signal Sct output by the recording paper cutting control unit 26. Along with the driving of the cutting motor 52, the movable blade 56 slides toward the fixed blade 54 in a manner of moderately rubbing against the fixed blade 54. As a result, the recording paper P conveyed along the conveying path between the fixed blade 54 and the movable blade 56 is pressed against the fixed blade 54. As a result, the recording paper P is cut. After that, the cut recording paper P is discharged to the outside of the mobile printer 1 via the discharge port 160. That is, the cutting motor 52, the fixed blade 54, and the movable blade 56 cut the recording paper P conveyed by the conveying unit 40. The structure including the cutting motor 52, the fixed blade 54, and the movable blade 56 corresponds to the aforementioned cutting unit 50. In addition, the cutting unit 50 cuts the recording paper P by pressing the movable blade 56 against the fixed blade 54.

[0096] Here, when the cutting unit 50 cuts the recording paper P, the recording paper P only needs to be pressed against either the fixed blade 54 or the movable blade 56. Therefore, the cutting unit 50 can also be configured to press the recording paper P against either the fixed blade 54 or the movable blade 56 by applying a force by a user or the like. That is, the cutting unit 50 can also cut the recording paper P when the recording paper P is pressed against the fixed blade 54 or the movable blade 56. In addition, when the cutting unit 50 has this configuration, the cutting unit 50 can also be configured to include only one of the fixed blade 54 or the movable blade 56.

[0097] Here, the fixed blade 54 and the movable blade 56 repeatedly cut the recording paper P. Therefore, it is required that the fixed blade 54 and the movable blade 56 maintain high cutting performance even when repeatedly pressed against the recording paper P. Such fixed blade 54 and movable blade 56 are preferably made of a metal that is suitable for the strength and properties of the blade and is easy to process the blade edge suitable for the blade. For example, it is preferably made of iron, steel, stainless steel, etc. In addition, as long as the fixed blade 54 and the movable blade 56 can cut the recording paper P when pressed against the recording paper P, the blade edges of the fixed blade 54 and the movable blade 56 can be linear, and can also be serrated. By making the blade edges of the fixed blade 54 and the movable blade 56 linear, the possibility of generating paper dust on the cut surface of the recording paper P is reduced. On the other hand, by making the blade edge of the fixed blade 54 or the movable blade 56 serrated, the fixed blade 54 or the movable blade 56 can cut the recording paper P with a smaller force, improving the convenience for the user.

[0098] It should be noted that, for example, the mobile printer 1 can also be configured to have a manual cutting machine near the discharge port 160.

[0099] The roll paper R wound with the recording paper P is accommodated in the roll paper accommodating portion 60 in an inserted manner. Such a roll paper accommodating portion 60 includes a partition portion 61, and is located between the first wiring board 80 and the paper pressing roller 48, the print head 30, the cutting motor 52, the fixed blade 54, and the movable blade 56 in the direction along the X direction. Specifically, the roll paper accommodating portion 60 is composed of a first a partition portion 61a, a second b partition portion 61b, and a third c partition portion 61c that are part of the partition portion 61. In addition, when the roll paper R is accommodated, the roll paper accommodating portion 60 is disposed in the accommodation space of the housing 100 such that the first a partition portion 61a, which is part of the partition portion 61, is located between the accommodated roll paper R and the first wiring board 80, the second b partition portion 61b, which is part of the partition portion 61, is located between the accommodated roll paper R and the cutting motor 52, and the third c partition portion 61c, which is part of the partition portion 61, is located between the accommodated roll paper R and the second surface 102.

[0100] Here, within the partition wall portion 61 included in the roll paper accommodating portion 60, the c-th partition wall portion 61c located between the accommodated roll paper R and the cutting motor 52 constitutes a part of the conveyance path for conveying the recording paper P. Thereby, miniaturization of the mobile printer 1 can be achieved.

[0101] In Figure 4A it shows the axis of rotation of the roll paper R, that is, the axis R1 along the Y direction. The roll paper R rotates about the axis R1, and thereby the recording paper P is pulled out from the roll paper R.

[0102] The power receiving module 11 is provided on the lid body 313.

[0103] The power receiving coil 110 receives the magnetic field Pmg of the high-frequency power transmission signal Vpt output based on the power transmission unit 4. That is, a magnetic field Pmg is formed around the power receiving coil 110.

[0104] In addition, as Figure 4A shown, the housing 100 has a battery accommodating portion 70 for accommodating the battery module 13. The battery accommodating portion 70 is a concave space, which is located on the +X side relative to the power receiving module 11 and on the -Z side of the first wiring board 80, and opens on the -Z side of a part of the second surface 102. That is, the battery accommodating portion 70 is provided outside the housing 100. Therefore, there is the second surface 102 forming the battery accommodating portion 70 between the battery module 13 accommodated in the battery accommodating portion 70, the first wiring board 80 accommodated in the accommodation space of the housing 100, and the roll paper accommodating portion 60. In other words, there is the second surface 102 between the battery module 13 and the first wiring board 80, and there is the second surface 102 between the battery module 13 and the roll paper accommodating portion 60.

[0105] In addition, a part of the second connector CN2 provided on the first wiring board 80 is exposed on the +Z side surface of the battery accommodating portion 70. Further, when the battery module 13 is accommodated in the battery accommodating portion 70, an unillustrated electrode of the battery module 13 is electrically connected to the second connector CN2. Thereby, the first wiring board 80 and the battery module 13 are electrically connected via the second connector CN2.

[0106] As described above, in the mobile printer 1, at least a part of the power supply unit 10 including the roll paper accommodating unit 60, the print head 30, the conveying unit 40, and the power receiving module 11, and the control unit 20 provided on the first wiring board 80 are accommodated in the accommodation space formed inside the housing 100, and the battery module 13 is accommodated in the battery accommodation unit 70 provided outside the housing 100. In other words, the housing 100 includes a first surface 101, a second surface 102, a third surface 103, a fourth surface 104, a fifth surface 105, and a sixth surface 106, and is provided to cover at least a part of the roll paper accommodating unit 60, the print head 30, the conveying unit 40, the cutting unit 50, the power supply unit 10, and the control unit 20. Thereby, the housing 100 reduces the possibility of applying an impact from the outside to the roll paper accommodating unit 60, the print head 30, the conveying unit 40, the cutting unit 50, and the power supply unit 10 of the mobile printer 1.

[0107] In such a mobile printer 1, among the roll paper accommodating unit 60, the print head 30, the conveying unit 40, the cutting unit 50, and the control unit 20 accommodated in the accommodation space of the housing 100, the control unit 20 is located near the fifth surface 105, the print head 30, the conveying unit 40, and the cutting unit 50 are located near the sixth surface 106, and in the direction along the direction from the fifth surface 105 toward the sixth surface 106, the roll paper accommodating unit 60 is located between the control unit 20 and the print head 30, the conveying unit 40, and the cutting unit 50. That is, with respect to the roll paper accommodating unit 60, the conveying unit 40, and the control unit 20, they are located in the order of the control unit 20, the roll paper accommodating unit 60, and the conveying unit 40 in the direction along the direction from the fifth surface 105 toward the sixth surface 106. With respect to the roll paper accommodating unit 60, the cutting unit 50, and the control unit 20, they are located in the order of the control unit 20, the roll paper accommodating unit 60, and the cutting unit 50 in the direction along the direction from the fifth surface 105 toward the sixth surface 106. With respect to the roll paper accommodating unit 60, the print head 30, and the control unit 20, they are located in the order of the control unit 20, the roll paper accommodating unit 60, and the print head 30 in the direction along the direction from the fifth surface 105 toward the sixth surface 10. In other words, the shortest distance between the control unit 20 and the fifth surface 105 is shorter than the shortest distance between the control unit 20 and the sixth surface 106, the shortest distance between the conveying unit 40 and the fifth surface 105 is longer than the shortest distance between the conveying unit 40 and the sixth surface 106, the shortest distance between the cutting unit 50 and the fifth surface 105 is longer than the shortest distance between the cutting unit 50 and the sixth surface 106, and the shortest distance between the print head 30 and the fifth surface 105 is longer than the shortest distance between the print head 30 and the sixth surface 106.

[0108] Accordingly, the head drive signal Sdr, the medium conveyance signal Str, and the medium cut-off signal Sct output by the control unit 20 are all transmitted from the fifth surface 105 side to the sixth surface 106 side in the accommodation space of the housing 100. Accordingly, the possibility of noise being superimposed on the head drive signal Sdr, the medium conveyance signal Str, and the medium cut-off signal Sct is reduced, and the possibility of malfunction occurring in the mobile printer 1 is reduced by the mutual cancellation of the head drive signal Sdr, the medium conveyance signal Str, and the medium cut-off signal Sct.

[0109] Figure 4B FIG. is an example showing a schematic configuration of the mobile printer 1 in a state where the cover 312 is opened with respect to the housing 311. It should be noted that in Figure 4B shows the same XYZ as Figure 2 and Figure 3

[0110] In Figure 4B a schematic configuration relationship of a part of the components of the mobile printer 1 is shown. Figure 4B The arranged positions of the respective components shown are schematic positions for explanation and are not necessarily precise.

[0111] It should be noted that in the example of Figure 4A in order to avoid complicating the drawing, the drawing of a part of the components shown in Figure 4B is omitted, however, the components shown in Figure 4B are also provided in Figure 4A

[0112] In the housing 311, a control unit 20, a mechanical unit UN1, and a roll paper R are provided, and a battery module 13 is installed.

[0113] The -Z side surface of the housing 311 is the second surface 102, and the +Z side surface of the housing 311 is the seventh surface 511.

[0114] The +Z side surface of the cover 312 is the first surface 101, and the -Z side surface of the cover 312 is the eighth surface 521.

[0115] Here, in a state where the cover 312 is closed with respect to the housing 311, the seventh surface 511 of the housing 311 and the eighth surface 521 of the cover 312 face each other.

[0116] It should be noted that the seventh surface 511 on the +Z side of the housing 311 is, for example, a virtual plane. Actually, based on the perspective of observing the housing 311 in the direction from the +Z side to the -Z side, there are internal structural components of the housing 311 that form a concave-convex structure.

[0117] ​​The lid body 312 has a first end portion E1 as the end portion on the -X side and a second end portion E2 as the end portion on the +X side.

[0118] In the present embodiment, a first rotatable portion 411 is provided at the second end portion E2 of the lid body 312, and the lid body 312 is supported by the first rotatable portion 411 so as to be rotatable relative to the housing 311. The first rotatable portion 411 is provided, for example, inside the housing 311.

[0119] Here, the first rotatable portion 411 may be, for example, a hinge or the like.

[0120] In the present embodiment, the power receiving module 11 is disposed inside the belt clip 313. In the present embodiment, when viewed along the Z direction, although the components of the belt clip 313 overlap, the power receiving module 11 is disposed inside the outermost component that is farthest from the housing 311.

[0121] The mobile printer 1 includes a first wiring 412 that electrically connects the power receiving module 11 and the battery module 13.

[0122] In the present embodiment, the first wiring 412 extends in such a manner as to pass through the inside of the belt clip 313 and enter the inside of the housing 311 until it reaches the battery module 13 pulled into the inside of the housing 311.

[0123] In the present embodiment, as Figure 4B shown, in a state where the lid body 312 is in the open position, it is possible to take out the roll paper R from the roll paper accommodating portion 60 and mount the roll paper R on the roll paper accommodating portion 60. Further, as Figure 4A shown, in a state where the lid body 312 is in the closed position, a discharge port 160 is formed.

[0124] Figure 4C is a diagram showing an example of the back side of the mobile printer 1. It should be noted that in Figure 4C , the same XYZ as Figure 2 and Figure 3 is shown.

[0125] Here, in the present embodiment, for the sake of convenience of explanation, the second surface 102 of the housing 311 on the side where the belt clip 313 is provided is referred to as the back side, but it is not necessarily limited thereto.

[0126] In Figure 4C , the second surface 102 of the housing 311 of the mobile printer 1, the belt clip 313, and the battery module 13 accommodated in the battery accommodating portion 70 are shown.

[0127] In addition, in Figure 4CIn [the figure], a first connection position 313a indicating the position where the second surface 102 of the housing 311 of the mobile printer 1 is connected to the tape cassette 313 is shown.

[0128] Here, in the present embodiment, a structure in which the battery module 13 is provided on the second surface 102 on the -Z side of the mobile printer 1 is shown. However, as another example, a structure in which the battery module 13 is provided on the third surface 103 on the -Y side or the fourth surface 104 on the +Y side of the mobile printer 1 may also be adopted.

[0129] In the present embodiment, the battery module 13 is detachable from the battery housing portion 70 of the housing 311 of the mobile printer 1. In the present embodiment, the battery module 13 has a structure that is detachable from the battery housing portion 70 in a specified insertion / removal direction.

[0130] When the battery module 13 is installed in the battery housing portion 70, the circuit terminals of the battery module 13 are electrically connected to the circuit terminals inside the mobile printer 1.

[0131] Figure 4D It is a figure showing an example of the arrangement position of the power receiving module 11 when using the protective cover 321. Note that in Figure 4D [the figure], [the XYZ] same as Figure 2 and Figure 3 is shown.

[0132] Here, Figure 4D the example of

[0133] In Figure 4D [the figure], an example of the situation when observing the tape cassette 313 from the perspective of observing the +Z side from the -Z side is shown.

[0134] The power receiving module 11 is provided on the surface on the -Z side of the tape cassette 313.

[0135] The power receiving module 11 may also be attached to the surface on the -Z side of the tape cassette 313 with an adhesive or the like, for example. In this case, as an example, the power receiving coil 110 constituting the power receiving module 11 may also be attached to the surface on the -Z side of the tape cassette 313.

[0136] In addition, in Figure 4D [the figure], a case where a protective cover 321 covering the power receiving module 11 is provided is shown. In this example, the protective cover 321 has a transparent component structure and does not contact the power receiving module 11. In the present embodiment, the protective cover 321 is used to protect the wiring.

[0137] In Figure 4DIn the example, a first a-wiring 412a is shown as a part of the first wiring 412 connected to the power receiving module 11 and exposed to the outside. In this example, the first a-wiring 412a is also covered by the protective cover 321 and does not contact the protective cover 321.

[0138] Here, various forms can be adopted as the form of the protective cover 321, such as its shape or material.

[0139] It should be noted that the protective cover 321 may not necessarily be provided.

[0140] A specific example of the structure of the power receiving module 11 will be described.

[0141] Then, by using Figure 5 A specific example of the structure of the power receiving module 11 will be described.

[0142] Figure 5 FIG. is a diagram showing an example of the structure of the power receiving module 11. As Figure 5 shown, the power receiving module 11 includes a power receiving coil 110 and a power receiving circuit 120.

[0143] The power receiving coil 110 receives, in a non-contact manner, a magnetic field Pmg corresponding to a power transmission signal Vpt based on a power supply voltage signal Vac from a power transmission unit 4 provided outside the mobile printer 1 as a power receiving signal Vpr. Such a power receiving coil 110 has an annular coil 111 that transmits the power receiving signal Vpr corresponding to the magnetic field Pmg, and a molding member 112 provided to cover the annular coil 111.

[0144] The annular coil 111 includes a conductor such as copper formed in an annular shape. A third end TM1 as one end of the conductor and a fourth end TM2 as the other end are electrically connected to the power receiving circuit 120. In addition, a current corresponding to the magnetic field Pmg generated around the annular coil 111 flows in the annular coil 111. That is, a potential difference corresponding to this current is generated between the third end TM1 and the fourth end TM2 of the annular coil 111. The power receiving coil 110 outputs the potential difference generated between the third end TM1 and the fourth end TM2 of the annular coil 111 to the power receiving circuit 120 as the power receiving signal Vpr.

[0145] In addition, the molding member 112 provided to cover the annular coil 111 maintains the shape of the annular coil 111 and functions as an insulator, which reduces the possibility of a short-circuit abnormality occurring between the structures of the mobile printer 1 and the annular coil 111 due to impacts generated by contact between the annular coil 111 and various parts of the mobile printer 1. As a result, the possibility of a change in the characteristics of the annular coil 111 is reduced, and the power receiving sensitivity based on the magnetic field Pmg of the power receiving coil 110 is improved.

[0146] Such a power receiving coil 110 includes: a coil region 114 where a loop coil 111 for transmitting a power receiving signal Vpr is located; a coil inner region 113 located inside the coil region 114; and a coil outer region 115 located outside the coil region 114.

[0147] The power receiving circuit 120 converts the power receiving signal Vpr output from the power receiving coil 110 into a second DC voltage signal Vdc2 and outputs it. Specifically, the power receiving circuit 120 includes a voltage conversion circuit 121, a connector 122, and a second wiring board 123 on which the voltage conversion circuit 121 and the connector 122 are provided.

[0148] The voltage conversion circuit 121 includes: a rectifying circuit that rectifies the high-frequency power receiving signal Vpr; a smoothing circuit that smooths the rectified voltage output by the rectifying circuit; and a voltage conversion circuit that outputs the smoothed voltage output by the smoothing circuit as the second DC voltage signal Vdc2 by transforming the voltage value to a specified voltage value. In addition, the second DC voltage signal Vdc2 output by the voltage conversion circuit 121 is transmitted in the second wiring board 123 and output from the power receiving module 11 via the connector 122.

[0149] As described above, in the power receiving module 11, the power receiving coil 110 receives a voltage signal based on the magnetic field Pmg, and the power receiving module 11 outputs the power receiving signal Vpr corresponding to the magnetic field Pmg to the power receiving circuit 120. The power receiving circuit 120 generates the second DC voltage signal Vdc2 with a specified voltage value based on the power receiving signal Vpr output by the power receiving coil 110 and outputs it from the connector 122.

[0150] The power receiving module 11 configured as such receives the magnetic field Pmg output from the power transmission unit 4 provided outside the mobile printer 1 in a non-contact manner.

[0151] An example of the alignment between the power receiving coil 110 and the power transmission coil 6 will be described.

[0152] Using Figure 6A and Figure 6B , an example of the alignment between the power receiving coil 110 and the power transmission coil 6 is shown. In this example, for simplicity of illustration, a case where the shape of the coil is disc-shaped is illustrated, but the shape of the coil can be any shape.

[0153] Figure 6A is an exploded view showing an example of the power receiving coil 110.

[0154] In this example, the power receiving coil 110 is formed by overlapping a first magnetic array 611, a first coil 612, a magnetic shield 613, and a metal shield 614.

[0155] Here, the first coil 612 is a planar coil in which a conductor is wound in concentric circles.

[0156] The magnetic shielding member 613 is made of a material such as iron and is a planar plate.

[0157] The metal shielding member 614 is made of copper, for example, and is a planar plate.

[0158] The magnetic shielding member 613 and the metal shielding member 614 have the same or similar planar shapes, and the first coil 612 has the planar shape included in the regions of the planar shapes of the magnetic shielding member 613 and the metal shielding member 614.

[0159] The first magnetic array 611 has a circumferential planar shape along a circumference that is more outside than the region of the planar shape of the first coil 612. In this example, instead of being connected at one part of the circumference, it has two ends at that part.

[0160] For example, the unconnected region of such a first magnetic array 611 can also be used for passing the wire of the coil or the wiring connected to the wire.

[0161] In this example, the first magnetic array 611 is disposed at a position adjacent to the first coil 612. It should be noted that the magnet of the first coil 612 and the first magnetic array 611 can be separated, for example.

[0162] Figure 6B It is a diagram showing an example of the alignment of the power receiving coil 110 and the power transmitting coil 6.

[0163] In Figure 6B , it is schematically illustrated, and the schematic appearances of the power receiving coil 110 and the power transmitting coil 6 are shown for explanation.

[0164] In addition, in Figure 6B , in order to easily observe the power receiving coil 110 and the power transmitting coil 6, they are shown separated to the extent that they do not overlap in the drawing.

[0165] It should be noted that in this embodiment, the structure of the power transmitting coil 6 is shown to be the same as that of the power receiving coil 110, but other structures can also be adopted.

[0166] In Figure 6B , an example of the arrangement relationship between the power receiving coil 110 and the power transmitting coil 6 is shown.

[0167] The power transmitting coil 6 is composed of a combination of the second coil 621, the second magnetic array M1, etc. The second coil 621 and the second magnetic array M1 in the power transmitting coil 6 correspond to the first coil 612 and the first magnetic array 611 in the power receiving coil 110.

[0168] When non - contact power supply is performed from the power - transmitting coil 6 to the power - receiving coil 110, the planar surface of the power - transmitting coil 6 and the planar surface of the power - receiving coil 110 are opposed to each other.

[0169] In addition, in this example, the first magnetic array 611 of the power - receiving coil 110 and the second magnetic array M1 of the power - transmitting coil 6 are positioned by the force of magnetic attraction between the two in a state where they are exactly opposed to each other. As a result, the first coil 612 of the power - receiving coil 110 and the second coil 621 of the power - transmitting coil 6 are positioned to be exactly opposed to each other.

[0170] Here, as a structure for aligning the power - receiving coil 110 and the power - transmitting coil 6, other structures can also be adopted.

[0171] It should be noted that if non - contact charging is performed without aligning the power - transmitting coil 6 and the power - receiving coil 110, there may be a situation where the coil positions do not match each other, and there may be a situation where power loss increases and heat is generated due to the positional deviation between the coils.

[0172] In response to this, when the power - transmitting coil 6 and the power - receiving coil 110 are aligned by magnets, for example, even if the user does not pay attention to the positions of the coils relative to each other, the positional relationship between the coils can be made the optimal configuration.

[0173] As described above, in the mobile printer 1 according to the present embodiment, the power - receiving coil 110 is provided on one side of the tape holder 313, and non - contact power supply can be achieved in a state where the tape holder 313 is installed. Thus, the constraints on the arrangement of the power - receiving coil 110 can be eliminated.

[0174] Here, in the mobile printer 1 according to the present embodiment, for example, not only the usage mode in a state of being placed on the ground is considered, but also the usage mode in a state of being attached to pants or the like using the tape holder 313 is envisioned. Therefore, when non - contact power supply is adopted for the mobile printer 1, assuming that the power - receiving coil 110 is provided on the second surface 102 of the housing 311, it is possible that there may be an interference between the tape holder 313 and the power - receiving coil 110. However, in the present embodiment, such a problem can be eliminated.

[0175] It should be noted that the posture of using the mobile printer 1 is not particularly limited. For example, it can be placed on a table or the like with the second surface 102 where the battery is set as the lower surface, or it can also be used in a posture where the sixth surface 106 or the fifth surface 105 of the mobile printer 1 is the upper surface in a state where the tape holder 313 is used.

[0176] As a structural example, the printing device includes a housing 311, a cover 312, a battery housing portion 70, a battery, a tape holder 313, and a power - receiving module 11.

[0177] Here, in the present embodiment, the small mobile printer 1 is an example of a printing device. Further, in the present embodiment, the battery module 13 is an example of a battery.

[0178] The housing 311 has a roll paper accommodating portion 60 for accommodating roll paper.

[0179] The lid 312 is connected to the housing 311 and opens and closes the roll paper accommodating portion 60.

[0180] A battery accommodating portion 70 is formed in the housing 311.

[0181] The battery is accommodated in the battery accommodating portion 70.

[0182] The tape holder 313 is attached to the housing 311.

[0183] The tape holder 313 includes a power receiving module 11 that receives a power transmission signal Vpt from the outside by non-contact power supply through the power receiving coil 110 and supplies power to the battery.

[0184] Therefore, in the printing device, since the power receiving coil 110 of the power receiving module 11 is provided in the tape holder 313, the configuration restrictions of the power receiving coil 110 can be eliminated.

[0185] In the printing device, for example, a power receivable area is provided on the side of the tape holder 313.

[0186] Here, the power receivable area is an area that can receive power non-contact from the power transmission coil 6 through the power receiving coil 110 of the power receiving module 11. For example, it may be an area near the surface of the tape holder 313 on the -Z side.

[0187] Further, in the printing device, since the power receiving coil 110 is provided in the tape holder 313, for example, the necessity of removing the tape holder 313 during non-contact charging can also be eliminated.

[0188] It should be noted that the roll paper R accommodated in the roll paper accommodating portion 60 is pulled out to become the recording paper P.

[0189] Further, in the present embodiment, when the lid 312 is opened with respect to the housing 311, there is also an opening 44 for pulling out the recording paper P from the roll paper.

[0190] Further, the power receiving coil 110 may be provided inside the tape holder 313, for example, or may be provided on the outer surface of the tape holder 313. In the present embodiment, the power receiving module 11, or at least the power receiving coil 110 of the power receiving module 11 is provided inside the tape holder 313, or on the outer surface on the Z side, or on the outer surface on the +Z side. In this case, it can also be considered that the power receiving module 11, or at least the power receiving coil 110 of the power receiving module 11 is integrated with the tape holder 313.

[0191] It should be noted that since the clip 313 has a built-in power receiving coil 110 or the like, it can also be enlarged. In this case, the coil surface for non-contact charging in the clip 313 can be formed into a relatively large plane, and in addition, a stable surface can be ensured when placed on a table or the like.

[0192] For example, the printing device can be used not only by being moved, but also by being placed on a plane such as a table like a stationary printer for use. In this case, when the printing device is set on a table or the like, if the printing device is set via the clip, the possibility of an unstable setting can be considered. However, if the clip 313 is enlarged, a stable setting state can be ensured.

[0193] When power is supplied from the power transmission coil 6 to the power receiving coil 110, for example, it can be formed into a state where the power transmission coil 6 or the unit portion including the power transmission coil 6 does not contact the outer surface of the clip 313, or it can be formed into a state where they contact. The distance between the power transmission coil 6 and the power receiving coil 110 is a distance at which appropriate power transmission and reception can be performed.

[0194] As a structural example, in the printing device, the clip 313 is connected to the second surface 102 which is the second surface of the housing at the second surface of the housing, and this second surface of the housing is different from the seventh surface 511 which is the first surface of the housing where the cover 312 is arranged relative to the housing 311.

[0195] Therefore, in the printing device, the power receiving coil 110 of the power receiving module 11 and the battery are arranged on different surfaces, and the power receiving module 11 and the battery are not connected through the cover 312. Thus, in the printing device, for example, compared with the wiring path when the clip is connected to the cover 312, the wiring path of the first wiring 412 can be shortened.

[0196] It should be noted that the structure related to this structural example may not necessarily be used.

[0197] As a structural example, in the printing device, the clip 313 is detachable.

[0198] Therefore, in the printing device, the user can easily remove and install the clip 313 as needed, and the convenience of the user can be improved.

[0199] Here, the structure may be as follows: when the power receiving coil 110 is arranged on the clip 313, for example, contact terminals are respectively arranged on the clip 313 and the housing 311, and when the clip 313 and the housing 311 are installed, the contact terminals of each other are electrically connected.

[0200] It should be noted that the structure related to this structural example may not necessarily be used.

[0201] As a structural example, in a printing apparatus, a positioning member is provided in a tape holder 313, and the positioning member can be connected to a first magnet of a power transmission coil 6 that generates a magnetic field Pmg based on a power transmission signal Vpt.

[0202] Here, Figure 6B in the example of, the second magnetic array M1 of the power transmission coil 6 is an example of the first magnet, and the first magnetic array 611 of the power reception coil 110 is an example of the positioning member.

[0203] Therefore, in the printing apparatus, it is possible to easily align the coils of the power transmission coil 6 and the power reception coil 110 with each other using magnets. For example, even when the cover body 312 is the upper surface, it is possible to eliminate the need to invert the printing apparatus for contactless charging.

[0204] Figure 6B in the example of, a case where the positioning member of the power reception coil 110 is made of a magnet is shown. However, the positioning member may also be made of metal.

[0205] In addition, in this example, a case where the positioning member is provided in the power reception coil 110 is shown. However, as another example, the positioning member may be provided in the tape holder 313.

[0206] It should be noted that the structure related to this structural example may not necessarily be used.

[0207] As a structural example, in a printing apparatus, a protective cover body 321 is provided on the tape holder 313.

[0208] Therefore, in the printing apparatus, it is possible to shorten a first wiring line 412 between the power reception coil 110 of the power reception module 11 and the battery, and it is possible to suppress transmission loss.

[0209] Here, in the printing apparatus, for example, the first wiring line 412 connecting the power reception module 11 and the battery may also be provided between the tape holder 313 and the protective cover body 321.

[0210] It should be noted that the structure related to this structural example may not necessarily be used.

[0211] As a structural example, in a printing apparatus, when viewed from the insertion / removal direction of the battery with respect to the housing 311, a first connection position 313a of the tape holder 313 with the housing 311 does not overlap with the battery.

[0212] Therefore, in the printing apparatus, it is a structure in which the connection point of the tape holder 313 with the housing 311 does not overlap with the battery, and it is possible to prevent the tape holder 313 from interfering with the insertion / removal of the battery.

[0213] In addition, in the printing apparatus, shortening the first wiring 412 between the power receiving coil 110 of the power receiving module 11 and the battery can suppress transmission loss.

[0214] It should be noted that the structure related to this configuration example may not necessarily be used.

[0215] Here, in the present embodiment, the case where the belt clip 313 is attached to the -X side of the housing 311 in the X direction is shown. However, as another example, a structure in which the belt clip 313 is attached to the +X side of the housing 311 may also be adopted. In this case, for example, the power receiving coil 110 is close to the battery, and the shortest distance between the connection position of the belt clip 313 and the housing 311 and the battery is shorter than the shortest distance between the connection position of the belt clip 313 and the housing 311 and the roll paper accommodating portion 60. Thereby, the first wiring 412 between the power receiving coil 110 of the power receiving module 11 and the battery can be shortened, and transmission loss can be suppressed.

[0216] As described above, the embodiments have been described in detail with reference to the drawings. However, the specific structure is not limited to this embodiment, and includes designs and the like within the scope not departing from the gist of the present disclosure.
