A wall portion on the plate surface side to which the case 12 is connected is configured as an attachment wall portion 66a, and the case 12 can be attached to and detached from the attachment wall portion 66a.

  The guide portion 50 functions to connect the case 12 to the attachment portion 66 of the attachment member 60 in a detachable manner and to guide the case 12 so that the posture of the case 12 with respect to the attachment portion 66 becomes a predetermined posture at the time of the connection. To do. The guide portion 50 includes two case-side connecting portions (first case-side connecting portion 51 and second case-side connecting portion 52) provided on the case 12 and two attaching portions 66 provided on the attaching member 60. It is provided with attachment member side connection parts (the 1st attachment member side connection part 53 and the 2nd attachment member side connection part 54), and two case side connection parts and two attachment member side connection parts are connected, respectively. Thus, the attachment member 60 and the case 12 are coupled.

  The two case side coupling parts are composed of a first case side coupling part 51 and a second case side coupling part 52 configured as magnets, and the two mounting member side coupling parts are arranged on the first mounting member side configured as magnets.

  The first case side connecting portion 51 and the first mounting member side connecting portion 53 have different polarities, and the first case side connecting portion 51 and the first mounting member side connecting portion 53 are connected to each other by suction. It has become. For example, the first case side connecting portion 51 is configured as a permanent magnet whose surface portion is configured as an N pole, and the first mounting member side connecting portion 53 is configured as a permanent magnet whose surface portion is configured as an S pole. They are sucked together when their surface portions face each other. Moreover, the polarity of the 2nd case side connection part 52 and the 2nd attachment member side connection part 54 mutually differs, and these 2nd case side connection parts 52 and the 2nd attachment member side connection part 54 are mutually attracted | sucked and connected. It is the composition which becomes. For example, the second case side connecting portion 52 is configured as a permanent magnet whose surface portion is configured as an S pole, and the second mounting member side connecting portion 54 is configured as a permanent magnet whose surface portion is configured as an N pole. They are sucked together when their surface portions face each other.

  The reading apparatus 10 configured as described above can continuously read the information code every time a predetermined trigger condition is satisfied or after a predetermined start condition is satisfied. For example, when the operation switch is pressed, the imaging start trigger is used, and after the operation switch is pressed, the imaging process is continuously performed by the imaging unit 23, and the information code is read each time the information code enters the imaging range. It may be. Alternatively, reading may be started on the condition that a predetermined state is detected by a sensor different from the operation switch 42. For example, a known proximity sensor that detects the proximity of an object in the forward direction of the case 12 may be provided, and when the object approaches, an illumination light source or an imaging unit may be operated to perform imaging and decoding. Alternatively, the voice input from the microphone is analyzed, and it is determined whether or not the voice corresponds to the predetermined voice (for example, whether or not a volume of a predetermined amount or more is detected or whether or not a voice having a predetermined waveform is detected). do it. This determination process may be performed by the reading device 10 or an external device.

(Main effects of this configuration)
According to this configuration, it is possible to realize a configuration in which the information code reader 10 can be worn and used without being held by a hand. Furthermore, in this configuration, since the case side can be detached while the part to be worn on the body (the body wearing part 62) is attached to the body, the removal work can be facilitated. Furthermore, since the body mounting portion 62 has a flexible structure that can be bent and deformed, the degree of freedom when mounting on the body is increased.

  The body wearing part 62 is configured to be maintained in a predetermined shape in a natural state when worn, and is configured to be elastically deformable. Since the body mounting portion 62 that is to be maintained in the prescribed shape by the elastic restoring force is attached in this way, it is easy to omit complicated tying work and the like when attaching to the body, thereby further facilitating the mounting. be able to.

  Moreover, the body mounting part 62 is comprised as an ear hooking part hung on a user's ear. In this configuration, since the reading device 10 is attached to the ear, the movement of the face and the entire reading device 10 are interlocked, and the reading direction can be easily determined according to the movement of the user's face. Further, since the attachment position is the ear, it is easy to wear even when other wearing tools (such as a helmet or glasses) are used.

  Further, the case 12 is detachably connected to a predetermined mounting portion 66 of the mounting member 60, and the posture of the case 12 with respect to the mounting portion 66 at the time of the connection is a predetermined posture (specifically, the user P's A guide unit 50 is provided for guiding the face so that the reading port 14 faces in the direction in which the face faces (the side in which the line of sight faces). In this configuration, in a configuration in which the reader 10 can be used by being attached to the body without being grasped by the hand, the case side can be easily detached from the body and can be easily reattached after the removal. The structure which can be performed to can be implement | achieved. In particular, at the time of remounting, the case 12 is guided more accurately by the guide portion 50 so that the posture of the case 12 becomes a predetermined posture with respect to the mounting portion 66 that is left attached to the user. It becomes easy to mount quickly so as to be in the position and orientation.

  In this configuration, the “predetermined posture” of the case 12 defined by the guide portion 50 is such that, for example, the longitudinal direction of the mounting portion 66 and the longitudinal direction of the case 12 coincide as shown in FIG. The side connecting portions and the attachment member side connecting portions are in contact with or close to each other.

  The guide portion 50 includes at least two case-side coupling portions provided in the case 12 and at least two attachment member-side coupling portions provided in the attachment portion 66 of the attachment member 60. The attachment member 60 and the case 12 are connected by connecting the case side connection portion and the two attachment member side connection portions, respectively. Thus, it is the structure connected so that two connection parts (case side connection part) provided in case 12 may match with at least two connection parts (attachment member side connection part) defined in attachment member 60. Therefore, it becomes easier to set the case 12 more accurately so that the direction of the case 12 faces a desired direction.

  Moreover, the guide part 50 has the one side magnet provided in one of the case 12 and the attachment part 66, and the magnetic body provided in the other of the case 12 and the attachment part 66 and attracted by the one side magnet. According to this configuration, the case 12 can be guided to a predetermined position of the mounting member 60 by using the attractive force generated between the one-side magnet and the other-side magnetic body, and the burden of alignment and connection is further reduced. can do.

  In the above configuration, the first case side connecting portion 51 and the second case side connecting portion 52, and the first mounting member side connecting portion 53 and the second mounting member side connecting portion 54 are all constituted by magnets. However, for example, the first case side connecting portion 51 and the second case side connecting portion 52 are constituted by magnets (one side magnet), and the first mounting member side connecting portion 53 and the second mounting member side connecting portion 54 are made of iron or the like. You may comprise by the well-known magnetic body. Alternatively, the first case side connecting portion 51 and the second case side connecting portion 52 are made of a magnetic material such as iron, and the first mounting member side connecting portion 53 and the second mounting member side connecting portion 54 are magnets (one side magnets). ). Alternatively, the first case side connecting portion 51 and the second mounting member side connecting portion 54 are configured by magnets, and the second case side connecting portion 52 and the first mounting member side connecting portion 53 are configured by a magnetic material such as iron. Also good.

  Specifically, two case side connection parts consist of the 1st case side connection part 51 and the 2nd case side connection part 52 which are comprised as a magnet, and two attachment member side connection parts are comprised as a magnet. It consists of a first attachment member side connection portion 53 and a second attachment member side connection portion 54. And the polarity of the surface part of the 1st case side connection part 51 and the polarity of the surface part of the 1st attachment member side connection part 53 are mutually different, These 1st case side connection part 51, the 1st attachment member side connection part 53, Are sucked to each other, for example, connected so that the surface portions are in contact with each other. Moreover, the polarity of the surface part of the 2nd case side connection part 52 and the polarity of the surface part of the 2nd attachment member side connection part 54 are mutually different, These 2nd case side connection part 52 and the 2nd attachment member side connection part 54, Are sucked to each other, for example, connected so that the surface portions are in contact with each other. Further, the surface portion of the first case side connecting portion 51 and the surface portion of the second mounting member side connecting portion 54 have the same polarity, and the surface portion of the second case side connecting portion 52 and the first mounting member side connecting portion are connected. The surface portion of the portion 53 has the same polarity.

When the attachment member side connecting portions 54) are in the opposing positional relationship, the case 12 can be accurately guided to the predetermined position of the guide portion 50 by using the suction force generated at each connecting position. On the contrary, the connection parts which do not correspond (that is, the first case side connection part 51 and the second attachment member side connection part 54, the second case side connection part 52 and the first attachment member side connection part 53) are the surface parts. Since they have the same polarity, even if the connection is attempted in such a direction as to face each other (reverse direction), the surface portions repel each other at each position and are not connected. Therefore, in the case of the normal orientation as shown in FIG. 10, it becomes easier to align the case 12 with the mounting member 60 more accurately and quickly, and abnormal connection in the reverse direction can be more reliably prevented. it can.

  The attachment member 60 includes a base portion 65 connected to the attachment portion 66, and a body attachment portion (user attachment portion) 62 extends from the base portion 65. The case 12 includes an opposing wall portion (attached portion) 12 a connected to the attaching portion 66 by the guide portion 50. Furthermore, a displacement adjustment unit 64 that can change the displacement of the mounting portion 66 with respect to the base portion 65 is provided. In this configuration, the displacement adjusting unit 64 can adjust the displacement of the mounting portion 66 with respect to the base portion 65 (specifically, the posture of the mounting portion 66 with respect to the base portion 65). Fine adjustment is facilitated so that the orientation of the imaging unit 23 when attached to the unit 66 becomes a more desirable direction.

  Further, in this configuration, the battery 49 is accommodated in the case 12. In this configuration, since the power source exists in the case 12, the information code can be continuously read without receiving external power supply while the case 12 is removed from the mounting member 60.

[Modification 2 of the first embodiment]
Next, Modification Example 2 of the first embodiment will be described.
The portable information code reader 10 according to the second modification has the same configuration as the representative example or the first modification of the first embodiment except for the magnet. Specifically, only the combination of the polarities of the surface portions of the first case side connecting portion 51, the second case side connecting portion 52, the first mounting member side connecting portion 53, and the second mounting member side connecting portion 54 is the first.

[Fourth Embodiment]
Next, a fourth embodiment will be described with reference to FIGS.
The portable information code reader 410 according to the fourth embodiment is different from the first embodiment or the modified example of the first embodiment only in the configuration of the mounting member, and other than that of the first embodiment or the first embodiment. It is the same as the modified example. Specifically, only the base portion and the body mounting portion are different from the first embodiment or the modified example of the first embodiment, and the other portions are the same as the modified example of the first embodiment or the first embodiment. For example, the apparatus main body 11 is the same as that of the first embodiment.

  The attachment member 460 used in the fourth embodiment has the same structure of the attachment portion 466 as the attachment portion 66 used in the first embodiment. On the other hand, the body mounting portion 462 (user mounting portion) is configured as a band member that is hung on the user's arm or finger, unlike the body mounting portion 62 used in the first embodiment. The body mounting portion 462 is configured in a substantially annular shape as a whole, with a pair of curved portions 462a and 462b arranged to face each other. And the front-end | tip part of a pair of curved part 462a, 462b is arrange | positioned facing each other, and the clearance gap is formed between front-end | tip parts. In the case where the body mounting portion 462 is configured to be approximately the size of a general finger, an attachment member is attached to the user's finger by holding the finger between the curved portions 462a and 462b and holding it in a ring shape. 460 can be installed. In addition, when the body wearing part 462 is configured to have a general wrist size, the wrist is placed between the curved parts 462a and 462b and held in a bracelet so that the user's arm is secured. The attachment member 460 can be attached.

  In this configuration, since the apparatus main body 11 is attached to a finger or an arm, it is easy to be interlocked with the movement of the hand while realizing a configuration that can be operated without being gripped by the hand.

  In any configuration of the fourth embodiment, the configuration of the opposing wall portion, the configuration of the mounting wall portion, and the configuration of the guide portion may be the same as those of the second embodiment or the third embodiment. .

[Modification Example of Fourth Embodiment]
In the modified example of the fourth embodiment, the mounting member 60 (FIG. 8, etc.) of the first embodiment and the mounting member 460 (FIG. 14, FIG. 15, etc.) of the fourth embodiment can be used. .

  In this configuration, the configuration of the apparatus main body 11 is the same as that of the first embodiment. In this configuration, the apparatus main body 11 also captures the image of the information code captured by the imaging unit 23 that captures the information code and the imaging unit 23. A processing unit for processing and a case 12 for holding the imaging unit 23 and the processing unit are provided. Each attachment member includes a user mounting portion and an attachment portion to which the case 12 is attached and detached, and is configured as a separate body from the case 12.

  In this configuration, a plurality of types of attachment members 60 and 460 can be attached to the user, and the case 12 is connected to the attached attachment member regardless of which attachment member is attached to the user. It is possible. In this case, the attachment member 60 and the attachment member 460 may be used alternatively, and both the attachment members 60 and 460 are attached, and the case 12 is attached to one of the attachment members. Also good.

  In this configuration, any one of a plurality of types of attachment members 60 prepared in advance can be selected and used, and can be mounted at an appropriate position according to the use situation. In addition, when using any type of mounting member 60, the case side can be used in common, so there is no need to prepare a case side structure for each type of mounting member 60, reducing the number of parts and cost. It becomes easy to reduce.

  In this configuration, when the case 12 is coupled to any one of the plurality of types of mounting members 60 and 460, the type of the mounting portion to which the case 12 is coupled may be determined. .

  For example, the mounting member 60 is configured such that a protrusion is provided at the position of the alternate long and short dash line A shown in FIG. 8 and the mounting member 460 is also provided with a protrusion at the position of the alternate long and short dash line B shown in FIG. The first hole and the second hole may be formed so as to correspond to the position A and the position B, respectively. For example, when the case 12 is attached to the attachment member 60, the protrusion formed at the position A is configured to be inserted into the first hole formed in the case 12. When the case 12 is mounted, the protrusion formed at the position B may be inserted into the second hole formed in the case 12. In this case, when a sensor for detecting the insertion of the protrusion into the first hole and the insertion of the protrusion into the second hole is provided, and the insertion of the protrusion into the first hole is detected by the sensor. Is determined to be attached to the attachment member 60, and if the insertion of the protrusion into the second hole is detected, it may be determined to be attached to the attachment member 460. In this configuration, the above-described sensor corresponds to an example of an attachment detection unit. The sensor and control circuit correspond to an example of a determination unit.

  Further, the apparatus main body 11 may perform a corresponding process according to the type determined by the determination unit. For example, when the determination unit detects that the case 12 is attached to the attachment member 60, the reading mode is set to the first mode, and the determination unit indicates that the case 12 is attached to the attachment member 460. If detected, the mode can be switched so that the reading mode is the second mode. In this case, for example, in the first mode when worn on the ear, an auto sense mode may be employed in which imaging processing is continuously performed and reading processing is automatically performed every time an information code is captured. Further, the second mode when worn on a finger or an arm may be a mode in which a reading process is performed each time the operation switch 42 is pressed. In this configuration, the control circuit 40 corresponds to an example of a setting change unit. The control circuit 40 corresponds to an example of a response processing unit, and functions to perform response processing according to the type determined by the determination unit.

  In this configuration, while using a plurality of types of mounting members 60, a configuration in which the case 12 can be used in common is realized, and on the case side, the type of the mounted mounting member 60 is determined and matched to that type. Can be performed.

  Note that the method of determining the type of the attachment member connected to the case 12 is not limited to this method. For example, the user may be able to input information on the type of attachment member into the case 12. Alternatively, each attachment member may be provided with a communication means so that a signal specifying its type can be transmitted from each attachment member to the case 12 side.

[Fifth Embodiment]
Next, a second embodiment will be described with reference to FIG.
The portable information code reader 510 according to the fifth embodiment includes a configuration of a mounting member 560 (specifically, a configuration of a base unit 565 that connects the mounting unit 66 and the body mounting unit 62 (user mounting unit)). (Specifically, the configuration of the displacement adjustment unit 564) is different from the first embodiment, and other than that is the same as the first embodiment. Accordingly, the rest of the description is the same as that of the first embodiment, and a detailed description thereof is omitted. For example, the same apparatus main body 11 as the first embodiment is used for the apparatus main body 11. In addition, the mounting portion 66 is the same mounting portion 66 as that of the first embodiment, and the body mounting portion 62 is also the same body mounting portion 62 as that of the first embodiment. In FIG. 16, the apparatus main body 11 is omitted.

  The displacement adjustment portion 564 used in the fifth embodiment is configured as a ball joint that connects the body mounting portion 62 side and the attachment portion 66 side with a spherical pair structure. In this configuration, the orientation of the attachment portion 66 relative to the base portion 565 can be changed three-dimensionally by connecting the base portion 565 and the attachment portion 66 with a spherical pair structure.

  In any configuration of the fifth embodiment, the configuration of the opposing wall portion, the configuration of the mounting wall portion, and the configuration of the guide portion may be the same as those of the second embodiment or the third embodiment. . Further, the structure of the base portion of the fifth embodiment may be applied to the fourth embodiment or a modification of the fourth embodiment.

[Sixth Embodiment]
Next, a sixth embodiment will be described.
A portable information code reader 610 according to the sixth embodiment is, for example, as shown in FIG. The configuration of FIG. 17 is a more specific example of the configuration of the first embodiment, and substantially includes all the features of the first embodiment. The features of the sixth embodiment can be applied to any of the above-described or later-described embodiments, and an example applied to the configuration of the first embodiment will be representatively described below. Moreover, in FIG. 17 etc., the same code | symbol as 1st Embodiment is attached | subjected about the part similar to 1st Embodiment, and detailed description is abbreviate | omitted.

  As shown in FIG. 17, in the portable information code reader 610 of this configuration, a magnetic sensor 601 is provided as one of the sensor units 46 assembled to the case 12. The magnetic sensor 61 functions as an attachment detection unit that detects that the case 12 is attached to the attachment member 60, and is configured by a known magnetic sensor such as a Hall element.

  In the example of the first embodiment, as described above, the two attachment member side connection portions (the first attachment member side connection portion 53 and the second attachment member side connection portion) made of permanent magnets are assembled to the attachment member 60. 54). The magnetic sensor 601 is disposed at a position that is affected by magnetism from at least one of the attachment member side coupling portions when the apparatus main body 11 is attached to the attachment member 60. In the example of FIG. When attached to the attachment member 60, the magnetic sensor 601 faces and approaches the second attachment member-side connecting portion 54. When the second attachment member side connecting portion 54 is not approaching (for example, when the case 12 is largely separated from the attachment member 60 as shown in FIG. 17), the magnetic sensor 601 has a first signal (non-detection). Signal). On the other hand, when the 1st case side connection part 51 and the 2nd case side connection part 52 connect with the 1st attachment member side connection part 53 and the 2nd attachment member side connection part 54, respectively, ie, the 2nd attachment member side connection part. When 54 approaches the magnetic sensor 601, a second signal (detection signal) different from the first signal (non-detection signal) is output. For example, when the surface portion of the second attachment member side coupling portion 54 has an N pole, the magnetic sensor 601 outputs a predetermined detection signal (an output signal exceeding a certain voltage level), for example, when the N pole approaches. What is necessary is just to comprise so that it may output. In this case, when an output signal exceeding a certain voltage level is issued from the magnetic sensor 601, the control circuit 40 determines “attached state”, and the output signal from the magnetic sensor 601 exceeds a certain voltage level. If not, it can be determined as “non-attached state”.

  Also, in the portable information code reader 10 of this configuration, for example, setting information as shown in FIG. 18A is stored in the memory 35 in advance, and the setting change process is performed according to the flow as shown in FIG. It has become. This setting change process is started after a start condition such as power-on is established, and can be performed in parallel with other processes. In this setting change process, after the process is started, the intensity of the output from the magnetic sensor 601 (for example, the output voltage level) is confirmed (S10), and it is determined whether or not the output intensity exceeds a certain level (S11). When the output intensity exceeds a certain level (that is, when the case 12 is attached to the attachment member 60), the process proceeds to Yes in S11, and the attachment state is set according to the setting information of FIG. Perform the combined settings. In the example of FIGS. 18A and 19, since it is determined that the volume is set to a low level in the “attached state”, the volume of a speaker, a buzzer, or the like when proceeding to Yes in S <b> 11. Is set to a small level (S12). The setting made in S12 corresponds to an example of the first setting. Conversely, when the output intensity confirmed in S10 does not exceed a certain level (that is, when the case 12 is in a detached state in which the case 12 is detached from the attachment member 60), the process proceeds to No in S11, and FIG. Set according to the removal status according to the setting information. In the example of FIGS. 18A and 19, since it is determined that the volume of the speaker, the buzzer, and the like is set to a high level (a level higher than the “small level”) in the detached state, the process proceeds to S11. If yes, the volume of the speaker, buzzer, etc. is set to a high level (S13). Note that the setting made in S13 corresponds to an example of a second setting.

  Note that the setting example illustrated in FIG. 18A is merely an example, and may be any example as long as the setting can be changed between a state where the case is attached to the attachment member and a state where the case is removed. For example, when the case 12 is attached to the attachment member 60 as shown in FIG. 18B, the vibration of a known vibrator provided in the case 12 is set to a predetermined small level, and the case 12 is attached to the attachment member 60. When the vibrator is removed from the vibrator, the vibration of the vibrator may be set to a predetermined large level larger than the small level. Alternatively, as shown in FIG. 18C, a known vibrator provided in the case 12 is turned off (operation stopped state) in the attached state, and the vibrator is turned on (operation permitted state) in the detached state. You may make it set.

  In this configuration, the control circuit 40 corresponds to an example of a setting change unit, and the portable information code reader is detected when the magnetic sensor 601 (attachment detection unit) detects that the case 12 is attached to the attachment member 60. The setting of the portable information code reader 10 is set to a predetermined first setting when the magnetic sensor 601 (attachment detection unit) does not detect the state where the case 12 is attached to the attachment member 60. Functions as a two-setting.

  In addition, the example of the attachment detection part shown here is an example to the last, and the structure shown in the modification of 4th Embodiment may be sufficient as an attachment detection part. That is, the attachment of the case to the mounting member may be detected by a method such as the modified example of the fourth embodiment. Moreover, it is not restricted to these examples, You may provide well-known proximity sensors, such as a pressure sensor and a photoelectric sensor, in one of an attachment member or a case, and may detect the proximity | contact of a case with respect to an attachment member.

According to this configuration, since the attachment member 760 is attached in a form supported by both ears, stability at the time of wearing increases, and it becomes easier to link the movement of the face and the case more stably. In addition, since the case 712 can be indirectly attached to the ear, the case 712 can be easily attached to the human body even when other wearing tools (such as a helmet or glasses) are used.

  In addition, a magnet is disposed on one of the case 712 and the attachment portion 766, and an attracting portion (for example, a magnet or other magnetic body) attracted by the magnet is disposed on the other, and the case is attached to the right mounting portion. When the case 712 is attached to the left attachment portion 780, the case 712 is attached to the left attachment portion 780. When the case 712 is attached to the left attachment portion 780, the case 712 and the right attachment portion 770 are held. 780 is held by the suction of the magnet and the suction portion. According to this configuration, even when the case 712 is attached to the right side of the face or the left side, the case 712 is easily attached using the attractive force of the magnet. In addition, the case can be easily removed and replaced from the mounting portion 766.

  Further, in the case 712, a holding portion (guide groove 713) configured to be able to be fitted to a held portion (surface portions 772, 782) formed in the attachment portion 766 is formed, and the case 712 is attached to the attachment portion 766. When attached to the holder, the holding portion and the held portion are configured to be fitted. In this configuration, when the case 712 is attached to the attachment portion 766, the case 712 can be held at least in a fitted state, so that the case 712 is not easily displaced.

  Specifically, as shown in FIGS. 32 and 34, a guide groove 713 having a pair of wall portions 713 a and 713 b facing each other is formed in the case 712. The attachment portion 766 includes held portions (surface portions 772 and 782) that are disposed and held between the pair of wall portions 713 a and 713 b in the guide groove 713 when the case 712 is attached to the attachment portion 766.

The polarity of each surface portion of the connecting portion 783b is the same. The polarity of the surface portion of the second case side connecting portion 752 is different from the polarity of the surface portions of the second right connecting portion 773b and the second left connecting portion 783b, and the first right connecting portion 773a and the first left connecting portion 783a. It is the same as the polarity of the surface part.

In this configuration, whether the case is mounted on the right side or the left side of the face, the case can be guided more strongly and more accurately to an appropriate position by using the force with which the magnets attract at least two positions. It is possible to reduce the burden of alignment and connection. Furthermore, even when the case is attached to the right side of the face or the left side, when the connection parts that do not correspond are attached so as to match each other, the connection parts that do not correspond have the same polarity. The connecting parts repel each other at the position, and are not connected. Therefore, whether the case is mounted on the right side or the left side of the face, it is easier to align the case with the mounting portion more accurately and quickly when it is in the correct orientation. This abnormal connection can be prevented more reliably.

In addition, the attachment portion is supported by being supported on one of the user's ears, a front extending portion extending from the supported portion, a holding portion connected to the front extending portion and holding the case At the time of attachment when the attachment portion is attached to the user, the front extension portion is arranged to extend to the front side of the supported portion, and is held at a position in front of the ear hole of the ear that supports the supported portion. The part is arranged.

The holding portion includes a back surface portion facing the user's face at a position before the ear canal and a surface portion disposed on the opposite side of the back surface portion, and is configured to hold the case by the surface portion. ing.
In this configuration, since the case is held by the surface portion arranged at a position away from the user's face, the case held by the surface portion does not block the user's ear canal, and the user can hear surrounding sounds. It becomes easy to hear.

In addition, a lead-out hole that leads out sound is formed in the wall portion of the case that is attached to the attachment portion. When the case is attached to the attachment portion, it is led out by a covering portion that forms a part of the attachment portion. At least a part of the hole is covered, and when the case is removed after being detached from the attachment portion, a portion of the lead-out hole that is covered by the covering portion at the time of attachment is exposed.
In this configuration, when the case is placed near the face, the sound can be relatively suppressed by closing the outlet hole, even when the sound source is near the user's ear, It can suppress that a loud sound reaches a user too much. On the other hand, when the case is not worn easily away from the face, the sound can be made relatively loud by exposing the lead-out hole, even if the sound source is some distance away from the user's ear Makes it easier for people to reach.

The second left connecting part 783b may be the same magnet as in the seventh embodiment.

  In 7th Embodiment and other embodiment, the structure which attaches a case to a right attachment part was illustrated by connecting at least 2 case side connection parts and at least 2 right side connection parts as a 1st guide part, respectively. However, in any configuration, the case may be a configuration in which the case is attached to the right mounting portion by connecting the three or more case side connecting portions and the three or more right connecting portions. In addition, as the second guide portion, the configuration in which the case is attached to the left-side mounting portion by connecting the two case-side connecting portions and the two left-side connecting portions, respectively, but in any configuration, there are three or more cases The case may be configured such that the case is attached to the left mounting portion by connecting the side connecting portion and the three or more left connecting portions. Moreover, the structure which attaches a case to a right mounting part by connecting one case side connection part and one right side connection part may be sufficient. Moreover, the structure which attaches a case to a left side mounting part by connecting one case side connection part and one left side connection part may be sufficient.

  In the seventh embodiment and other embodiments, as the first guide portion, at least two case side connection portions and at least two right side connection portions are respectively connected by magnets, and the case is attached to the right mounting portion. Although illustrated, at least two case side connection parts and at least two right side connection parts may be connected by a fitting structure or a locking structure. Moreover, at least two case side connection parts and at least two right side connection parts may each be configured in a sheet shape, and each case side connection part may be connected to a corresponding right connection part with a hook-and-loop fastener structure. In addition, as the second guide part, the configuration in which the case is attached to the left mounting part by connecting the two case side connecting parts and the two left side connecting parts, respectively, is illustrated. The left connecting portion may be connected by a fitting structure or a locking structure. Further, at least two case-side connecting portions and at least two right-side connecting portions may each be configured in a sheet shape, and each case-side connecting portion may be connected to the corresponding left-side connecting portion with a hook-and-loop fastener structure.

  In the configuration of the seventh embodiment and other embodiments, the portion to which the case is attached (the surface portion 772 and the surface portion 782 in the seventh embodiment) is the portion to be attached to the body (the right ear attachment portion 762a and the left in the seventh embodiment). The ear mounting portion 762b) may be configured to be displaceable. For example, the rear surface portion 771 and the front surface portion 772 fixed to the right ear attachment portion 762a are separated, and the front surface portion 772 is separated from the rear surface portion 771 by a ratchet structure (structure similar to FIG. 10) or a spherical pair structure (FIG. The structure may be displaceable by the same structure as in FIG. Similarly, the back surface portion 781 and the front surface portion 782 fixed to the left ear mounting portion 762b are separated, and the front surface portion 782 is separated from the back surface portion 781 by a ratchet structure (structure similar to FIG. 10) or a spherical pair structure ( It may be displaceable by the same structure as in FIG.

  In the seventh embodiment, the right ear mounting portion is illustrated as the right ear mounting portion 762a. However, any configuration that can be attached to the right ear is acceptable. For example, the configuration may be such that the same ear insertion part as in the first embodiment is inserted into the ear hole of the right ear and attached, or the right ear is sandwiched. Or you may use together the structure attached to a right ear, the structure inserted in the ear hole of a right ear, and the right ear. For example, the right ear mounting portion 762a (right ear hooking portion) of the seventh embodiment and the ear insertion portion of the first embodiment may be used together or attached to the right ear. Moreover, although the left ear hook part was illustrated as a left ear attachment part, what is necessary is just a structure which can be attached to a left ear. For example, a configuration in which the same ear insertion portion as that in the first embodiment is inserted into the ear hole of the left ear and attached may be used, or a configuration in which the left ear is sandwiched may be used. Or you may use together the structure attached to a left ear, the structure inserted in the ear hole of a left ear, and the structure attached on both sides of a left ear. For example, the left ear attaching portion 762b (left ear hooking portion) of the seventh embodiment and the ear insertion portion of the first embodiment may be used together and attached to the left ear.

  The seventh embodiment exemplifies a configuration that is not attached when the right ear side or the left ear side is attached in the opposite direction (that is, when an incompatible connecting portion is to be attached). The idea is not limited to the example of the seventh embodiment. For example, in the configuration of the seventh embodiment, only the second case side connecting portion 752, the first right side connecting portion 773a, and the first left side connecting portion 783a may be replaced with a magnetic material such as iron. Or in the structure of 7th Embodiment, you may replace only the 1st case side connection part 751, the 2nd right side connection part 773b, and the 2nd left side connection part 783b with magnetic bodies, such as iron. Also in this case, if the left and right sides are attached in the opposite direction, the magnets will repel each other and will not be mounted.

  In the seventh embodiment, when the case 712 is attached to the attachment member 760, the lead-out holes 720 are all covered by the covering portion (surface portion 772 or surface portion 782) that forms part of the attachment member 760, and the case 712 is covered. In this example, when removing the mounting member 760 from the mounting member 760, the lead hole 720 exposes a portion (that is, all the leading holes 720) covered with the covering portion (the surface portion 772 or the surface portion 782) during mounting. Not limited to. For example, when the case 712 is attached to the attachment member 760, only a part of the outlet hole 720 is covered by the covering portion (surface portion 772 or surface portion 782), and when the case 712 is removed from the attachment member 760, the case 712 is removed. In the lead-out hole 720, a portion (that is, a part of the lead-out hole) covered with the covering portion (surface portion 772 or surface portion 782) at the time of attachment may be exposed.

  In the seventh embodiment and other configurations to which the same configuration is applied, the case 712 can be held with respect to the mounting member 760 by a magnet. In this configuration, if a stationary attachment member is provided separately from the attachment member 760 and a structure (for example, a structure similar to the surface portion 772 and the surface portion 782) is provided on the attachment member, the device The main body 711 can be detached from the attachment member 760 and attached to a bare stationary attachment member to be used as a fixed scanner.

  In the seventh embodiment and other configurations to which the same configuration is applied, a mounting portion can be freely prepared by a third party such as a user by disclosing the mounting portion shape and the position and structure of the permanent magnet to the third party. Will be able to.

  In the seventh embodiment, the first case side connection part, the second case side connection part, the first right side connection part, the second right side connection part, the first left side connection part, and the combination of the polarities of the second left side connection part are exemplified. However, it is not limited to this example. For example, the polarity of the surface portion of the first case side connecting portion 751 and the polarity of the surface portion of the second case side connecting portion 752 may be the same polarity (for example, both are N poles). In this case, the polarity of the surface portion of the first right connecting portion 773a and the polarity of the surface portion of the second right connecting portion 773b are the same polarity (for example, both are S poles), and the surface portion of the first left connecting portion 783a is The polarity and the polarity of the surface portion of the second left connecting portion 783b may be the same polarity (for example, both are S poles). In this configuration, the polarity of the magnet is unified at a plurality of positions on the case 712 side, and the polarity of the magnet is also unified in each of the right side mounting portion 770 and the left side mounting portion 780, so the case 712 is mounted on the right side of the face. Even if it is attached to the left side, the structure is strong against displacement. That is, when the case 712 is attached to the right attachment portion 770 or the left attachment portion 780, the suction force is easily maintained even if the case 712 is slightly deviated from the normal position. In particular, in the configuration of the seventh embodiment, as shown in FIG. 32, a plurality of case-side coupling portions are arranged in a direction intersecting the longitudinal direction of the case 712 (specifically, a vertical direction orthogonal to the longitudinal direction). Therefore, the magnetic force of one case side connection part is easy to reach close to the other case side connection part. In such a configuration, if the polarity of one case side connecting portion and the other case side connecting portion is reversed, the mounting member side connecting portion to be attached to one case side connecting portion at the time of mounting is the other case. If they are displaced so as to approach the side connecting portion, they repel each other, and such a repulsive force tends to hinder smooth connection. On the other hand, according to the said structure, such a repulsion can be suppressed and it becomes easy to connect a case to an attachment member smoothly.
