[0003] [Patent Document 1] US2021 / 0111580 Summary of the Invention [Problem to be solved by the invention]
[0004] However, in the example where the power receiving coil is provided in the head section, the head section becomes large, resulting in poor balance of the code reader.Furthermore, in the example where the power receiving coil is provided in the foot section, in order to have the power receiving coil face the power transmitting coil of the stand from above, it is necessary to support the code reader upright while placing the bottom surface of the foot section where the power receiving coil is provided on the stand, which makes the support of the code reader unstable.
[0005] This invention has been made in consideration of the above-mentioned problems, and aims to reduce the size of the head part of a code reading device having a receiving coil for wireless charging, and to enable wireless charging of the code reading device while stably supporting the code reading device. [Means for solving the problem]
[0006] The code reading device according to the present invention is a code reading device that has a power transmission unit incorporating a power transmission coil and can be wirelessly charged by the power transmission coil of a stand that can be installed on a horizontal surface, and is equipped with a head unit incorporating a light receiving sensor, a grip unit extending in the axial direction from the head unit, a grip end unit provided at the end of the grip unit on the opposite side of the head unit in the axial direction, and a power storage unit, and the grip unit has a trigger switch for starting detection by the light receiving sensor, which is provided between the head unit and the grip end unit on the detection area side of the light receiving sensor, The end portion has a grip end bottom surface that intersects with the axial direction, a grip end front surface that extends from the grip end bottom surface toward the trigger switch, and a receiving unit that has a built-in receiving coil and is provided on the front surface of the grip end, and in the first form in which the code reading device is placed on a stand installed on a horizontal surface, the head portion and the receiving unit are supported vertically by the stand, the receiving unit is adjacent to the transmitting unit from above in the vertical direction, the receiving coil faces the transmitting coil, and wireless charging is performed from the transmitting coil to the storage unit via the receiving coil.
[0007] The code reading system according to the present invention is a code reading system comprising: a code reading device having a head portion incorporating a light receiving sensor, a grip portion extending axially from the head portion, and a power storage portion; and a stand having a power transmission portion incorporating a power transmission coil and capable of being installed on a horizontal surface, wherein the code reading device has a grip end portion provided at the end of the grip portion on the opposite side to the head portion in the axial direction, and the grip portion has a trigger switch for starting detection by the light receiving sensor, the trigger switch being provided between the head portion and the grip end portion on the detection area side of the light receiving sensor. The grip end portion has a grip end bottom surface that intersects with the axial direction, a grip end front surface that extends from the grip end bottom surface toward the trigger switch, and a power receiving unit that has a built-in power receiving coil and is provided on the grip end front surface, and in a first form in which the code reading device is placed on a stand installed on a horizontal surface, the head portion and the power receiving unit are supported vertically by the stand, the power receiving unit is adjacent to the power transmitting unit from above in the vertical direction, the power receiving coil faces the power transmitting coil, and wireless charging is performed from the power transmitting coil to the power receiving coil.
[0008] In the present invention (code reader and code reading system) configured as described above, the power receiving unit incorporating the power receiving coil is provided on the front surface of the grip end, not in the head unit, thereby avoiding an increase in the size of the head unit due to the provision of the power receiving coil. Furthermore, in the first mode in which the code reader is placed on a stand placed on a horizontal surface, the head unit and the power receiving unit are supported vertically by the stand. In other words, by supporting the code reader at two locations, the head unit and the power receiving unit, the stand can stably support the code reader. Furthermore, by supporting the power receiving unit on the stand and approaching the power transmitting unit of the stand from above, wireless charging is possible. As a result, the size of the head unit of the code reader, which has a power receiving coil for wireless charging, can be reduced, and the code reader can be wirelessly charged while stably supported. [Effects of the Invention]
[0009] With the present invention configured in this manner, it is possible to reduce the size of the head portion of the code reading device, which has a receiving coil for wireless charging, and to wirelessly charge the code reading device while stably supporting the code reading device.

[0011] Fig. 1 is a side view showing a schematic configuration of a code reading device, and Fig. 2 is a block diagram showing an outline of the electrical configuration of the code reading device of Fig. 1. Here, in a state in which the code reading device 1 faces the surface Wf of the workpiece W to read the code attached to the surface Wf of the workpiece W with the code reading device 1, a front-to-rear direction Dfs is shown where appropriate, with the side of the workpiece W relative to the code reading device 1 being the front side Sf and the side opposite the workpiece W relative to the code reading device 1 being the rear side Sb.
[0012] As shown in FIG. 1 , the code reading device 1 includes a head portion 11, a grip portion 12, and a grip end portion 13. The grip portion 12 extends in an axial direction Da that intersects with the front-to-rear direction Dfs between the head portion 11 and the grip end portion 13. In other words, the head portion 11 is provided at one end of the grip portion 12, and the grip end portion 13 is provided at the other end (the end opposite to the one end) of the grip portion 12. The head portion 11 has a head body 111, the grip portion 12 has a grip body 121, and the grip end portion 13 has a grip end body 131, and the head body 111, the grip body 121, and the grip end body 131 form a housing 14 that houses the various components built into the code reading device 1.
[0013] The head body 111 of the head unit 11 has an opening 112 on the front side Sf, and when reading a code, the opening 112 faces the surface Wf of the workpiece W. The head unit 11 has an illumination unit 2 (FIG. 2) that irradiates the surface Wf of the workpiece W with illumination light Li, and an imaging unit 3 that captures reflected light Lr from the surface Wf using a light-receiving sensor 31 to generate a code image Ic. The illumination unit 2 and the imaging unit 3 are housed within the head body 111. The light-receiving sensor is not particularly limited, and at least one of an area sensor, a line sensor, and a laser light-receiving element can be used. The illumination light Li is irradiated onto the surface Wf of the workpiece W through the opening 112 from the illumination unit 2. The reflected light Lr is generated by reflecting the illumination light Li on the surface Wf of the workpiece W, and the reflected light Lr enters the light-receiving sensor 31 of the imaging unit 3 from the surface Wf of the workpiece W through the opening 112.
[0014] The light receiving sensor 31 included in the imaging unit 3 focuses the reflected light Lr onto a solid-state imaging element using a focusing lens, which is an objective lens facing the surface Wf of the workpiece W. The solid-state imaging element generates a code image Ic by receiving the reflected light Lr focused by the focusing lens. The optical axis of this light receiving sensor 31 (i.e., the optical axis Ac of the focusing lens of the light receiving sensor 31) is parallel to the aforementioned front-to-rear direction Dfs.
[0015] The grip portion 12 has a trigger switch 122 provided on the front side Sf of the grip body 121. A user can operate the trigger switch 122 with a finger while holding the grip body 121 in his / her hand.
[0016] The code reading device 1 also includes a controller 4 that controls each part of the code reading device 1, and a memory unit 5 that stores data used and generated in the code reading device 1. The controller 4 and memory unit 5 are housed in a housing 14. The controller 4 is a processor, i.e., a CPU (Central Processing Unit). The memory unit 5 is a storage device such as a ROM (Read Only Memory) or RAM (Random Access Memory).
[0017] The controller 4 causes the lighting unit 2 to perform an illumination operation of irradiating the surface Wf of the workpiece W with illumination light Li, and causes the imaging unit 3 to perform an imaging operation of receiving reflected light Lr with a solid-state imaging element and generating a code image Ic. Furthermore, the controller 4 acquires the code image Ic generated by the imaging unit 3 and decodes the code image Ic. Thus, code reading is performed through a series of operations, including the illumination operation by the lighting unit 2, the imaging operation by the imaging unit 3, and the decoding by the controller 4. For example, the controller 4 performs code reading when it detects a user's operation of the trigger switch 122. The code reading result, i.e., the decoding result Rd obtained by the controller 4 decoding the code image Ic, is stored in the memory unit 5. The code reading device 1 transmits the decoding result Rd stored in the memory unit to an external host or the like via a communication means (not shown) such as WLAN.
[0018] The code reading device 1 also includes a power supply unit 7 housed in the housing 14. The power supply unit 7 has a battery 71 that stores power, and the battery 71 supplies power to the illumination unit 2, the imaging unit 3, the controller 4, the storage unit 5, and the trigger switch 122. That is, the illumination unit 2, the imaging unit 3, the controller 4, the storage unit 5, and the trigger switch 122 each operate using power supplied from the battery 71. That is, the battery 71 constitutes a power storage unit.
[0019] Fig. 3 is a side view showing an example of a specific external configuration of a code reader, and Fig. 4 is a perspective view showing an example of a specific external configuration of a code reader. In Fig. 3, components housed in the housing 14 of the code reader 1 are indicated by dashed lines.
[0020] As described above, the grip body 121 of the grip portion 12 extends in the axial direction Da between the head body 111 of the head portion 11 and the grip end body 131 of the grip end portion 13. The grip body 121 is inclined in the front-to-rear direction Dfs so as to move toward the rear side Sb as it moves away from the head body 111. In other words, the grip body 121 is inclined toward the rear side Sb with respect to the head body 111. The grip body 121 extends from the end of the rear side Sb of the head body 111, and the head body 111 protrudes from the grip body 121 toward the front side Sf (in other words, toward the trigger switch 122).
[0021] The grip end body 131 of the grip end portion 13 protrudes from the grip body 121 of the grip portion 12 toward the trigger switch 122. The trigger switch 122, which is disposed on the front side Sf of the grip body 121, is provided at the end of the grip body 121 on the head body 111 side.
[0022] The grip end body 131 also has a bottom surface 132 and a front surface 133. The bottom surface 132 is provided at the end of the grip end body 131 on the opposite side from the grip body 121 in the axial direction Da, and the front surface 133 extends from the end of the front side Sf of the bottom surface 132 toward the trigger switch 122 in the axial direction Da (in other words, toward the grip body 121). The bottom surface 132 is provided so as to intersect with the axial direction Da, and the end of the bottom surface 132 on the front surface 133 side is chamfered so as to bend toward the front surface 133. The front surface 133 is also provided so that the end of the front surface 133 on the trigger switch 122 side is located on the forward side Sf of the end of the front surface 133 on the opposite side from the trigger switch 122.
[0023] A power receiving unit 72 of the power supply unit 7 is provided facing this front surface 133. This power receiving unit 72 is housed inside the grip end main body 131. The power receiving unit 72 also incorporates a power receiving coil 721 for receiving power transmitted wirelessly, and the power receiving coil 721 faces the front surface 133 from inside the grip end main body 131. The power received by the power receiving coil 721 is transmitted from the power receiving coil 721 to the battery 71 and stored in the battery 71.
[0024] Furthermore, as shown in Fig. 4, the code reader 1 is equipped with a finger bar 15 that is detachably attached to the housing 14. Next, the configuration of the finger bar 15 and the configuration for attaching the finger bar 15 to the housing 14 will be described using Figs. 5, 6, and 7 in combination. Here, Fig. 5 is a perspective view showing the configuration of the finger bar, Fig. 6 is a perspective view showing the attachment portion of the finger bar provided in the head portion, and Fig. 7 is a perspective view showing the attachment portion of the finger bar provided in the grip end portion.
[0025] The finger bar 15 has a stay plate 16 extending from the grip end portion 13 to the head portion 11 on the front side Sf of the grip portion 12. This stay plate 16 is provided at a distance from the grip portion 12 in the front-to-rear direction Dfs. One end 161 of the stay plate 16 is supported by the head portion 11, and the other end 162 (opposite to the one end) of the stay plate 16 is supported by the grip end portion 13. Specifically, the end 161 of the stay plate 16 is detachably attached to an attachment portion 114 provided at the end of the front side Sf of the head main body 111, and the end 162 of the stay plate 16 is detachably attached to an attachment portion 134 provided at the end of the front side Sf of the grip end main body 131.
[0026] As shown in FIG. 4, the slide claw 17 is built into the end of the stay plate 16 on the end 161 side. The stay plate 16 is provided with an opening 163 on the front side Sf, and the slide claw 17 is exposed to the front side Sf through the opening 163. Therefore, a user can operate the slide claw 17 through the opening 163. The slide claw 17 is slidable relative to the stay plate 16 between a protruding position where it protrudes from the end 161 of the stay plate 16 and a retracted position where it is retracted from the end 161 of the stay plate 16 and fits inside the stay plate 16. As shown in FIG. 6, the mounting portion 114 of the head body 111 has a pair of engagement holes 115. The pair of engagement holes 115 are open on the surface of the head body 111 facing the grip end body 131. The slide claws 17, which face the pair of engagement holes 115 from the grip end body 131 side, engage with the pair of engagement holes 115 when positioned in the protruding position, and disengage from the pair of engagement holes 115 when positioned in the retracted position.
[0027] As shown in Fig. 5, a pair of engagement protrusions 164 is provided on the end 162 of the stay plate 16. In contrast, as shown in Fig. 7, the mounting portion 134 of the grip end body 131 has a pair of engagement holes 135. The pair of engagement holes 135 are open on the surface of the grip end body 131 facing the head body 111. The pair of engagement protrusions 164 of the stay plate 16 can be engaged with and disengaged from the pair of engagement holes 135 of the grip end body 131 from the grip end body 131 side.
[0028] The finger bar 15 also has a support plate 18 that extends from a middle portion 165 between ends 161 and 162 of the stay plate 16 to the rear side Sb (in other words, toward the grip body 121). As shown in FIG. 5, an engagement hole 182 is formed at the end 181 of the rear side Sb of the support plate 18. A support portion 123 is formed on the front side Sf of the grip body 121, and the engagement hole 182 of the support plate 18 can be engaged with and disengaged from the front side Sf of the support portion 123 of the grip body 121. This support portion 123 is formed on the grip end body 131 side of the trigger switch 122.
[0029] Therefore, the user The pair of engagement protrusions 164 on the end 162 of the stay plate 16 are engaged with the pair of engagement holes 135 of the grip end body 131, While the slide claws 17 are positioned at the storage position, the ends 161 of the stay plate 16 are opposed to the pair of engagement holes 115 of the head body 111, and the engagement holes 182 of the support plate 18 are fitted into the support portions 123, Slide the slide claw 17 from the retracted position to the extended position. By carrying out the above procedure, the finger bar 15 can be attached to the housing 14 of the code reader 1.
[0030] As described above, the stay plate 16 is spaced apart from the grip body 121 on the front side Sf, and spaces S1 and S2 are provided between the stay plate 16 and the grip body 121. Here, space S1 is provided closer to the head body 111 than the support plate 18, and space S2 is provided closer to the grip end body 131 than the support plate 18. Therefore, a user can hold the grip portion 12 with their hand by inserting, for example, their index finger into space S1 and their middle finger, ring finger, and little finger into space S2. Furthermore, the trigger switch 122 faces the space S1 from the grip body 121 side, and the user can operate the trigger switch 122 with their index finger inserted into space S1. The finger bar 15 allows a user to carry items other than the code reader 1 while holding the code reader 1 in their hand, thereby improving the gripping performance of the code reader 1.
[0031] Furthermore, the finger bar 15 has a plurality of mounting holes 166 that penetrate the stay plate 16. Therefore, by inserting screws into the mounting holes 166 and threading them into a support base that is provided separately from the code reading device 1, the finger bar 15 can be fastened to the support base. In other words, the user can use the code reading device 1 with the code reading device 1 fixed to the support base.
[0032] 4 and 6, the head unit 11 of the code reading device 1 has a hook portion 19. The hook portion 19 is provided to hook onto a stand (described later) when the head unit 11 is in a vertical position where it is positioned above the grip end portion 13. The hook portion 19 is provided at the end of the front side Sf of the head body 111 so as to protrude from a peripheral edge 113 of the opening 112 toward the opening 112. In particular, it protrudes from the peripheral edge 113 into the opening 112 at a hook position 116 at the end of the opening 112 opposite the grip end body 131 (in other words, the upper end of the opening 112 when in a vertical position).
[0033] The position of the hooking portion 19 is not limited to this, and depending on the type of code reading device 1, the hooking portion 19 is provided at a position different from the hooking position 116 on the periphery 113 of the opening 112. That is, in other types of code reading devices 1, hooking positions 117 are provided at the ends of the front side Sf of both sides of the head main body 111 of the head unit 11, and the hooking portions 19 are provided so as to protrude laterally from the head main body 111 at each hooking position 117.
[0034] Fig. 8 is a perspective view showing the stand for the code reading device, and Fig. 9 is a side view showing the stand for the code reading device. In Fig. 9, components built into the stand 9 are shown by dashed lines. Here, the configuration of the stand 9 will be described using a state in which the stand 9 is placed on a flat installation surface P.
[0035] The stand 9 has a base portion 90 extending in an extension direction De parallel to the installation surface P, and a contact surface 901 parallel to the extension direction De provided on the base portion 90 comes into contact with the installation surface P. The stand 9 also has a head mounting portion 91 and a grip end mounting portion 93 that face the head portion 11 and the grip end portion 13, respectively, of the code reading device 1 placed on the stand 9. In other words, the head mounting portion 91 is provided at one end of the base portion 90 in the extension direction De, and the grip end mounting portion 93 is provided at the other end (opposite to the one end) of the base portion 90 in the extension direction De.
[0036] The head mounting portion 91 has a head-facing surface 911 that faces, from the front side Sf, an end of the front side Sf of the head unit 11 of the code reading device 1 placed on the mounting base 9, and a pair of wall portions 912 that stand upright from both ends of the head-facing surface 911 in a width direction Dw perpendicular to the extension direction De. The pair of wall portions 912 stand upright from the head-facing surface 911 on the opposite side from the installation surface P (in other words, on the opposite side from the base portion 90). The pair of wall portions 912 are spaced apart in the width direction Dw and are arranged receding in the width direction Dw from the approach path Q of the head unit 11 that is placed on the head mounting portion 91 from the opposite side of the grip end mounting portion 93 in the extension direction De. The pair of wall portions 912 position the head unit 11 placed on the head mounting portion 91 so as to face the head-facing surface 911.
[0037] The stand 9 also has a support block 94 that protrudes from the head-opposing surface 911 of the head mounting portion 91 to the opposite side of the installation surface P. The support block 94 has an engaging member 941 and a block main body 942, and the engaging member 941 protrudes from the block main body 942 to the opposite side of the grip end mounting portion 93 in the extension direction De. The engaging member 941 engages with the hook portion 19 of the hook position 116 provided on the head portion 11 that faces the head-opposing surface 911. More specifically, as shown in FIGS. 8 and 9 , in a vertical installation mode in which the stand 9 is installed on the installation surface P (vertical surface) that is provided in the up-down direction of the paper, i.e., the vertical direction, the engaging member 941 engages with the hook portion 19 of the hook position 116 from below, and the code reading device 1 is supported in the vertical direction against gravity by the engaging member 941.
[0038] As described above, depending on the type of code reader 1, the hooking portion 19 is provided at hooking position 117 rather than at hooking position 116. The stand 9 is also configured to support the hooking portion 19 at hooking position 117 so that it can support the code reader 1 regardless of the type of code reader 1. That is, a pair of engaging members 951 that protrude inward are provided on the inner walls of the pair of wall portions 912. In the vertical installation mode, each engaging member 951 engages with the hooking portion 19 at each hooking position 117 from below, and the code reader 1 is supported vertically against gravity by the engaging members 951.
[0039] The grip end mounting portion 93 has a grip end opposing surface 931 that faces, from the front side Sf, the front surface 133 of the grip end portion 13 of the code reading device 1 placed on the mounting base 9. In a side view from the width direction Dw, the grip end opposing surface 931 is inclined with respect to the installation surface P. More specifically, the grip end opposing surface 931 is inclined so as to move away from the installation surface P as it moves away from the head mounting portion 91 in the extension direction De. The grip end mounting portion 93 also has a pair of wall portions 932 that stand upright from both ends of the grip end opposing surface 931 in the width direction Dw. The pair of wall portions 932 stand upright from the grip end opposing surface 931 on the side opposite to the installation surface P (in other words, the side opposite to the base portion 90), and position the front surface 133 of the grip end portion 13 placed on the grip end mounting portion 93 so as to face the grip end opposing surface 931. The pair of wall portions 932 are spaced apart in the width direction Dw, and a slit 933 is provided in the width direction Dw between the pair of wall portions 932. In other words, the slit 933 is a hole that opens in the direction in which the grip end opposing surface 931 is inclined with respect to the installation surface P.
[0040] Furthermore, the stand 9 includes a power transmission unit 96 provided to face the head-facing surface 911. This power transmission unit 96 is housed in the grip end mounting portion 93. The power transmission unit 96 also includes a power transmission coil 961 for wirelessly transmitting power, and the power transmission coil 961 faces the grip end-facing surface 931 from inside the grip end mounting portion 93.
[0041] The front surface 133 of the grip end portion 13 placed on the grip end mounting portion 93 comes into contact with the grip end facing surface 931 of the grip end mounting portion 93. As a result, the power transmitting coil 961 provided on the grip end facing surface 931 of the grip end mounting portion 93 faces the power receiving coil 721 provided on the front surface 133 of the grip end portion 13, and power can be supplied wirelessly from the power transmitting coil 961 to the power receiving coil 721.
[0042] The stand 9 also has a cable connector 967 provided between the grip end mounting portion 93 and the base portion 90. A cable insertion port that opens on the opposite side of the head mounting portion 91 in the extension direction De is provided for this cable connector 967, and a cable inserted into the cable insertion port can be connected to the cable connector 967. An example of such a cable is a USB (Universal Serial Bus) cable.
[0043] The stand 9 can be used in both a vertical installation form shown in Fig. 10 and a horizontal installation form shown in Fig. 11. Fig. 10 is a side view showing the stand installed in the vertical installation form, and Fig. 11 is a side view showing the stand installed in the horizontal installation form. In Figs. 10 and 11, the code reading device 1 facing the stand 9 for placement on the stand 9 is also shown.
[0044] 10, the stand 9 is installed on an installation surface P (vertical installation surface) parallel to the vertical direction Z (in other words, the vertical direction). As described above, the hooking portion 19 is provided at the hooking position 116 or the hooking position 117 depending on the type of code reading device 1. Meanwhile, the stand 9 is provided with an engaging member 941 and an engaging member 951 with which the hooking portion 19 can engage.
[0045] In the first hooking state in which the hooking portion 19 at the hooking position 116 is engaged with the engaging member 941, the code reading device 1 is supported by the engaging member 941 against gravity while hanging from the engaging member 941. In other words, the hooking position 116 where the hooking portion 19 engages with the engaging member 941 becomes a support point that supports the code reading device 1 against gravity. With the code reading device 1 supported at the hooking position 116 in this way, the head unit 11 is placed on the head mounting portion 91, and the grip end unit 13 is placed on the grip end mounting portion 93. The head unit 11 placed on the head mounting portion 91 is positioned by a pair of walls 912 so as to face the head facing surface 911. Furthermore, the grip end portion 13 placed on the grip end placing portion 93 is supported by a pair of wall portions 932 so as to face the grip end opposing surface 931, and the front surface 133 of the grip end portion 13 comes into contact with the grip end opposing surface 931. In this first hooking state, in the side view shown in Fig. 10, the center of gravity of the code reading device 1 is biased toward the opposite side of the stand 9 in the horizontal direction X from the hooking position 116, which is the support point of the code reading device 1. Therefore, a moment M is generated on the front surface 133 of the grip end portion 13, urging the front surface 133 toward the grip end opposing surface 931.
[0046] Furthermore, in the second hooking state in which the hooking portion 19 at the hooking position 117 is engaged with the engaging member 951, the code reading device 1 is supported by the engaging member 951 against gravity while hanging from the engaging member 951. In other words, the hooking position 117 where the hooking portion 19 engages with the engaging member 951 becomes a support point that supports the code reading device 1 against gravity. With the code reading device 1 supported at the hooking position 117 in this way, the head unit 11 is placed on the head mounting portion 91, and the grip end unit 13 is placed on the grip end mounting portion 93. The head unit 11 placed on the head mounting portion 91 is positioned by a pair of wall portions 912 so as to face the head facing surface 911. Furthermore, the grip end portion 13 placed on the grip end placing portion 93 is supported by a pair of wall portions 932 so as to face the grip end opposing surface 931, and the front surface 133 of the grip end portion 13 comes into contact with the grip end opposing surface 931. In this second hooking state, in the side view shown in Fig. 10, the center of gravity of the code reading device 1 is biased toward the opposite side of the stand 9 in the horizontal direction X from the hooking position 117, which is the support point of the code reading device 1. Therefore, a moment M is generated on the front surface 133 of the grip end portion 13, urging the front surface 133 toward the grip end opposing surface 931.
[0047] That is, in the first and second hooking states, a moment M acting on the front surface 133 of the grip end portion 13 urges the front surface 133 toward the grip-end-facing surface 931. This ensures reliable proximity between the power receiving unit 72 provided on the front surface 133 and the power transmitting unit 96 provided on the grip-end-facing surface 931. In this specification, proximity means close enough that charging can begin between the power receiving unit 72 and the power transmitting unit 96. In addition, while the power receiving unit 72 and the power transmitting unit 96 are in contact with each other in this embodiment, this is not a limitation. For example, a protrusion (not shown) may be provided on the grip-end-facing surface 931 to provide a gap (e.g., approximately 5 mm) between the power receiving unit 72 and the power transmitting unit 96 that allows charging. As a result, the power receiving coil 721 and the power transmitting coil 961 are brought into close proximity, allowing power to be supplied wirelessly from the power transmitting coil 961 to the power receiving coil 721.
[0048] 11 , the stand 9 is installed on an installation surface P (horizontal installation surface) parallel to the horizontal direction X. The code reading device 1 is then placed on the stand 9 from above. That is, the head unit 11 is placed on the head mounting portion 91 from above and is supported by the head mounting portion 91 in the vertical direction Z against gravity, and the grip end portion 13 is placed on the grip end mounting portion 93 from above and is supported by the grip end mounting portion 93 in the vertical direction Z against gravity. In other words, the weight of the grip end portion 13 acting on the front surface 133 of the grip end portion 13 presses the front surface 133 against the grip end opposing surface 931. This ensures reliable proximity between the power receiving unit 72 provided on the front surface 133 and the power transmitting unit 96 provided on the grip end opposing surface 931. As a result, power receiving coil 721 and power transmitting coil 961 can be brought close to each other, and power can be supplied wirelessly from power transmitting coil 961 to power receiving coil 721.
[0049] As described above, the code reader 1 has the finger bar 15 that extends from the grip end portion 13 toward the head portion 11 on the trigger switch 122 side (front side Sf) of the grip portion 12. In addition, spaces S1 and S2 for the user's hands holding the grip portion 12 are provided between the finger bar 15 and the grip portion 12. The finger bar 15 has an attachment hole 166 for attaching the code reader 1 to a support stand that is provided separately from the code reading system consisting of the code reader 1 and the stand 9.
[0050] Furthermore, when the code reader 1 is placed on the stand 9 that is installed vertically or horizontally, the head portion 11 and the grip end portion 13 contact the head mounting portion 91 and the grip end mounting portion 93 of the stand 9, respectively, and the finger bar 15 is located between the grip portion 12 and the stand 9 and contacts or is separated from the stand 9. In this way, interference between the finger bar 15 and the stand 9 prevents the head portion 11 or the grip end portion 13 from floating above the stand 9. As a result, reliable proximity between the power receiving portion 72 provided on the front surface 133 and the power transmitting portion 96 provided on the grip end-opposing surface 931 is ensured.
[0051] The stand 9 is equipped with an advancing / retracting mechanism that advances and retracts engaging members 941 and 951 for supporting the code reader 1. Figures 12A, 12B, and 12C are diagrams that schematically show an example of a mechanism that advances and retracts the engaging members that support the code reader 1. These engaging members 941 and 951 function to support the code reader 1 in the vertical installation mode, and therefore the description of Figures 12A to 12C will be given assuming that the stand 9 is installed in the vertical installation mode.
[0052] FIG. 12A shows an advancing / retreating mechanism 97 that moves the engaging member 941 forward and backward in the vertical direction Z relative to the block main body 942. The advancing / retreating mechanism 97 is housed in the head mounting portion 91. As shown in the "Side View" section of FIG. 12A, the advancing / retreating mechanism 97 has an advancing / retreating member 971. The advancing / retreating member 971 has an upright portion 972 that stands in the vertical direction Z and a support portion 973 that supports the upright portion 972 from the side, and the engaging member 941 is provided at the upper end of the upright portion 972. The advancing / retreating mechanism 97 also has an eccentric cam 974 that supports the advancing / retreating member 971 from below. As shown in the "Front View" section of FIG. 12A, the eccentric cam 974 is rotatable 90 degrees around a rotation center C, and contacts the support portion 973 of the advancing / retreating member 971 from below with a peripheral surface 975 whose distance from the rotation center C changes depending on the rotation angle around the rotation center C. The advancing and retreating mechanism 97 also has a compression spring 976 that biases the support portion 973 from the opposite side (upper side) of the eccentric cam 974 toward the eccentric cam 974 side (lower side).
[0053] In this configuration, when the rotation angle of the eccentric cam 974 is angle C1, the eccentric cam 974 pushes the engaging member 941 upward in the figure against the biasing force of the compression spring 976, causing the engaging member 941 to rotate about the rotation shaft 977, and the engaging member 941 is positioned at a retracted position retracted into the support block 94. When the rotation angle of the eccentric cam 974 is angle C2, the biasing force of the compression spring 976 pushes the engaging member 941 downward in the figure, causing the engaging member 941 to rotate about the rotation shaft 977, and the engaging member 941 is positioned at an advanced position protruding upward from the support block 94. When the engaging member 941 is pressed by an external force in the extended position, the spring 976 is compressed, allowing the engaging member 941 to move to the retracted position. This allows the code reading device 1 to be removed from and attached to the stand 9.
[0054] FIG. 12B shows an advancing / retreating mechanism 98 that moves a pair of engaging members 951 forward and backward in the horizontal direction X relative to a pair of wall portions 912. The advancing / retreating mechanism 98 is housed in the head mounting portion 91. As shown in FIG. 12B, the advancing / retreating mechanism 98 has a pair of advancing / retreating members 981 that are spaced apart in the horizontal direction X. The advancing / retreating members 981 extend in the horizontal direction X, and an engaging member 951 is attached to the outer end of each of the pair of advancing / retreating members 981 so that the engaging member faces inward. The advancing / retreating members 981 are also formed with a spring storage slit 982 that extends in the horizontal direction X. The advancing / retreating mechanism 98 also has an eccentric cam 984 that is provided between the pair of advancing / retreating members 981 in the horizontal direction X. As shown in FIG. 12C, the eccentric cam 984 is provided coaxially with the eccentric cam 974 and is rotatable around a rotation center C that is common to the eccentric cam 974. Furthermore, rotary levers attached coaxially to the eccentric cams 974, 984 are provided on the back surface of the base portion 90 (the surface opposite the head-facing surface 911), and when a user rotates the rotary lever, the eccentric cams 974, 984 rotate integrally with the rotary lever. The eccentric cam 984 contacts the inner ends of each of the pair of advancing and retreating members 981 at a peripheral surface 985 whose distance from the rotation center C changes depending on the rotation angle around the rotation center C. Furthermore, the advancing and retreating mechanism 98 has a compression spring 986 arranged in a spring housing slit 982 provided in the advancing and retreating member 981, and the compression spring 986 biases the advancing and retreating member 981 toward the eccentric cam 984 from the opposite side of the eccentric cam 984. This compression spring 986 is provided for each of the pair of advancing and retreating members 981.
[0055] In this configuration, when the rotation angle of the eccentric cam 984 is angle C1, the eccentric cam 984 presses the engaging member 951 outward against the biasing force of the compression spring 986, and the engaging member 951 is located at a retracted position retracted into the wall portion 912. On the other hand, when the rotation angle of the eccentric cam 984 is angle C2, the advancing / retreating member 981 is pressed inward by the biasing force of the compression spring 986, and the engaging member 951 is located at an advanced position protruding inward from the wall portion 912. When the engaging member 951 is pressed at the advanced position by an external force, the spring is compressed, and the engaging member 951 is moved to the retracted position. This makes it possible to remove the code reading device 1 from and attach it to the stand 9.
[0056] 13 is a block diagram showing the configuration of the power supply unit of the code reader 1. The power supply unit 7 includes a charging IC 73, which controls the battery 71 to store the power received by the power receiving unit 72 from the power transmitting unit 96 and the supply of the power stored in the battery 71 to each unit of the code reader 1. The power supply unit 7 also includes a load switch 74, a main power supply 75, and a power-saving mode management circuit 76. The power-saving mode management circuit 76 turns the load switch 74 on and off in response to commands from the controller 4 (CPU). When the power-saving mode management circuit 76 turns the load switch 74 on, the charging IC 73 supplies power extracted from the battery 71 to the main power supply 75 via the load switch 74. When the power-saving mode management circuit 76 turns the load switch 74 off, the power supply from the charging IC 73 to the main power supply 75 is cut off.
[0057] The main power supply 75 supplies power from the charging IC 73 to the illumination unit 2, the imaging unit 3, and the controller 4, allowing the illumination unit 2, the imaging unit 3, and the controller 4 to operate using this power. The power supply unit 7 may also include a supercapacitor (SCAP) 77. For example, when the code reader is used in a low-temperature environment, the resistance of the battery 71 increases. Therefore, the SCAP 77 is used as an assist power source when a large current is temporarily required. In this case, the battery 71 and the SCAP 77 form a power storage unit. In another embodiment, only the SCAP 77 may be provided instead of the battery 71. In this case, the SCAP 77 forms the power storage unit. Because the power supplied from the charging IC 73 to the main power supply 75 is limited, any surplus power during charging is stored in the SCAP 77. In this embodiment, power from the charging IC 73 is stored in the SCAP 77, so the SCAP 77 can also be used in applications where the supplied power is limited, such as USB power supply.
[0058] The power supply unit 7 also has a charging LED 78, and the lighting state of the charging LED 78 is controlled by the charging IC 73 according to the charging status of the battery 71. For example, when charging of the battery 71 is complete, the charging IC 73 lights the charging LED 78 in green, and when charging of the battery 71 is incomplete, the charging IC 73 lights the charging LED 78 in red.
[0059] Furthermore, the power supply unit 7 has a continuous power supply 79. The charging IC 73 supplies power taken from the battery 71 to the continuous power supply 79. The continuous power supply 79 also supplies the power supplied from the charging IC 73 to the power saving mode management circuit 76, the charging LED 78, the trigger switch 122, and the display SP, allowing the power saving mode management circuit 76, the charging LED 78, the trigger switch 122, and the display SP to operate using this power.
[0060] In this configuration, when the power-saving mode management circuit 76 turns off the load switch 74, the power supply to the main power supply 75 is cut off, and the operation of the illumination unit 2, the imaging unit 3, and the controller 4 is stopped (power-saving mode). Meanwhile, even in the power-saving mode, power is still supplied from the charging IC 73 to the continuous power supply 79, allowing the power-saving mode management circuit 76, the charging LED 78, the trigger switch 122, and the display SP to operate. When the power-saving mode management circuit 76 detects that the trigger switch 122 or the display SP has been operated by the user, it turns on the load switch 74 and starts supplying power to the main power supply 75. That is, when the power-saving mode management circuit 76 detects an operation on a user-operable user-operable unit (trigger switch 122, display SP), it stops the power-saving mode and starts supplying power to the main power supply 75. The specific user-operated unit is not limited to this example and can be modified as appropriate.
[0061] 14 is a flowchart showing an example of power supply control executed by the code reader. In step S101, the charging IC 73 determines whether the code reader 1 is placed on the stand 9 based on whether power is being supplied to the power receiving unit 72. If it is determined that the code reader 1 is placed on the stand 9 (YES in step S101), the controller 4 determines whether the user has continued to operate the trigger switch 122 and the display SP for a first waiting time (e.g., 10 minutes) (step S102).
[0062] If the trigger switch 122 and the display SP are operated during the first standby time ("NO" in step S102), the process proceeds to the normal operation mode in step S105. On the other hand, if the trigger switch 122 and the display SP are not operated during the first standby time ("YES" in step S102), the power saving mode is executed (step S103). That is, the controller 4 transmits a power saving mode execution command to the power saving mode management circuit 76, and the power saving mode management circuit 76 turns off the load switch 74 upon receiving this command. Then, when the power saving mode management circuit 76 detects an operation of the trigger switch 122 or the display SP ("YES" in step S104), it turns on the load switch 74 and starts supplying power to the main power supply 75 (step S105, normal operation mode).
[0063] Furthermore, if it is determined in step S101 that the code reading device 1 is not placed on the stand 9 (if "NO" in step S101), the controller 4 determines whether or not the user has not operated the trigger switch 122 and the display SP continuously for a second waiting time (e.g., 90 minutes) longer than the first waiting time (step S106). If the trigger switch 122 and the display SP have been operated during the second waiting time (if "NO" in step S106), the process proceeds to step S105. On the other hand, if the trigger switch 122 and the display SP have not been operated during the second waiting time (if "YES" in step S106), the power saving mode is executed (step S103).
[0064] According to this control, when the code reading device 1 is not placed on the stand 9, it is highly likely that the code reading device 1 is in use, and therefore the code reading device 1 can be prevented from frequently switching to the power saving mode. Furthermore, when the code reading device 1 is placed on the stand 9, the code reading device 1 can be quickly switched to the power saving mode, thereby shortening the time required to charge the battery 71.
[0065] In the embodiment configured as described above, the power receiving unit 72 incorporating the power receiving coil 721 is provided on the front surface 133 of the grip end portion 13 (front surface of the grip end) rather than on the head unit 11, thereby preventing the head unit 11 from becoming larger due to the provision of the power receiving coil 721. Furthermore, in a horizontal installation configuration (first configuration) in which the code reading device 1 is placed on a stand 9 installed on a horizontal installation surface P (horizontal plane), the head unit 11 and the power receiving unit 72 are supported vertically by the stand 9. In other words, by being supported at two locations, the head unit 11 and the power receiving unit 72, the code reading device 1 can be stably supported by the stand 9. Furthermore, by bringing the power receiving unit 72 close to the power transmitting unit 96 of the stand 9 from above while being supported by the stand 9, wireless charging can be performed. As a result, it is possible to reduce the size of the head portion 11 of the code reading device 1, which has a receiving coil 721 for wireless charging, and to wirelessly charge the code reading device 1 while stably supporting the code reading device 1.
[0066] Providing the power receiving unit 72 on the front surface 133 of the grip end portion 13 also has the following advantage. That is, a configuration in which the power receiving unit 72 is provided on the bottom surface 132 is also conceivable. However, in such a configuration, the wall portion provided on the stand 9 to support the power transmitting coil 961 facing the bottom surface 132 becomes large, and there is a risk that the large wall portion will interfere with the grip end portion 13 when the grip end portion 13 is placed on the grip end placing portion 93. In contrast, by providing the power receiving unit 72 on the front surface 133 of the grip end portion 13, there is no need to provide such a large wall portion, and the grip end portion 13 can be easily placed on the grip end placing portion 93.
[0067] The stand 9 can be placed on a vertical installation surface P (vertical surface) and has a head mounting portion 91 on which the head unit 11 is placed. The head unit 11 has a hook portion 19 (first mating portion) provided at the end on the detection area side (front side Sf; if the light receiving element 31 constitutes a camera, this means the field of view side of the camera) of the light receiving element 31. The head mounting portion 91 also has engagement members 941, 951 (second mating portions) that engage with the hook portion 19 when the code reading device 1 is placed on the stand 9. In the vertical installation configuration (second configuration) in which the code reading device 1 is placed on the stand 9 installed on a vertical installation surface P, a moment M originating from the hook portion 19 engaged with the engaging member 941 (or 951) urges the power receiving unit 72 in a direction toward the power transmitting unit 96, causing the power receiving unit 72 to come into contact with the power transmitting unit 96, and the power receiving coil 721 faces the power transmitting coil 961, thereby wirelessly charging the battery 71 from the power transmitting coil 961 via the power receiving coil 721. In this configuration, when the code reading device 1 is hooked onto the stand 9 installed on the vertical installation surface P, a moment M is generated that urges the power receiving unit 72 in a direction toward the power transmitting unit 96. Therefore, simply by performing the simple task of hanging the code reading device 1 on the stand 9, the power transmitting unit 96 and the power receiving unit 72 can be reliably brought into contact with each other, and wireless charging of the code reading device 1 can be performed.
[0068] The stand 9 also has a head mounting portion 91 on which the head unit 11 is placed, and the head mounting portion 91 has a wall portion 912 for positioning the head unit 11 placed on the head mounting portion 91. When the head unit 11 is placed on the head mounting portion 91 of the stand 9 from above in the vertical direction Z with the stand 9 placed on a vertical installation surface P, the wall portion 912 is provided at a position retracted from an approach path Q along which the head unit 11 enters the head mounting portion 91. With this configuration, the head unit 11 can be easily placed on the head mounting portion 91 without being interfered with by the wall portion 912.
[0069] The stand 9 also has a grip end placing portion 93 on which the grip end portion 13 is placed, and the grip end placing portion 93 is inclined with respect to the installation surface P when the stand 9 is placed on a horizontal installation surface P, and has a grip end facing surface 931 (inclined surface) that is inclined with respect to the installation surface P when the stand 9 is placed on a vertical installation surface P. The power transmission unit 96 is provided on this inclined grip end facing surface 931. With this configuration, even if a foreign object adheres to the power transmission unit 96, the foreign object can fall along the inclination of the grip end facing surface 931 on which the power transmission unit 96 is provided. As a result, it is possible to prevent the foreign object from affecting wireless charging.
[0070] Specifically, the stand 9 has a head mounting portion 91 for mounting the head unit 11. In contrast, the grip end opposing surface 931, in a side view, is inclined in a direction away from the installation surface P on which the stand 9 is installed as it moves away from the head mounting portion 91. By inclining the grip end opposing surface 931 in this way, foreign matter adhering to the power transmission unit 96 can be dropped naturally by gravity.
[0071] The grip end placing portion 93 also has a wall portion 932 for positioning the grip end portion 13 placed on the grip end placing portion 93, and the wall portion 932 is provided with a slit 933 (hole) that opens in the direction in which the grip end opposing surface 931 is inclined. By providing the slit 933 in this manner, foreign matter can be naturally dropped from the power transmitting portion 96 through the slit 933 by gravity.
[0072] The code reader 1 also has a finger bar 15 extending from the grip end portion 13 toward the head portion 11 on the trigger switch 122 side (front side Sf) of the grip portion 12, and spaces S1, S2 for the user's hands holding the grip portion 12 are provided between the finger bar 15 and the grip portion 12. The finger bar 15 has mounting holes 166 for mounting to a support base (supporting portion) provided separately from a code reading system consisting of the code reader 1 and the stand 9. When the code reader 1 is placed on the stand 9, the head portion 11 and the grip end portion 13 contact the head mounting portion 91 and the grip end mounting portion 93 of the stand 9, respectively, and the finger bar 15 is located between the grip portion 12 and the stand 9 and is in contact with or separated from the stand 9. With this configuration, the code reader 1 can be placed on the stand 9 without interference from the finger bar 15.
[0073] The code reading device 1 also has a controller 4 (processor) for controlling the light receiving sensor 31, a charging IC 73 (detection circuit) for detecting the start of wireless charging of the battery 71, and a power saving mode management circuit 76 (control circuit) for supplying power transmitted from the power receiving coil 721 to the controller 4. When the charging IC 73 detects the start of wireless power supply to the battery 71 ("YES" in step S101), the power saving mode management circuit 76 (control circuit) reduces the amount of power supplied to the controller 4 (step S103). With this configuration, when the code reading device 1 is placed on the stand 9 and wireless power supply starts, the power supply to the controller 4 is cut off, thereby reducing unnecessary power consumption and shortening the time required for charging. Note that in the power saving mode 103, instead of cutting off the power supply to the controller 4, the controller 4 may be transitioned to an idle state to reduce power consumption of the controller 4.
[0074] Furthermore, even if the charging IC 73 detects the start of wireless charging of the battery 71, the power saving mode management circuit 76 continues to supply power to the trigger switch 122 from the continuous power source 79. When the trigger switch 122 is activated (i.e., operated), the power saving mode is canceled, thereby enabling the controller 4 to control the light receiving sensor 31 (steps S104 and S105). With this configuration, operating the trigger switch 122 makes it easy to switch from the energy saving mode to the normal operation mode.
