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 right side connecting portion 73a is configured as a permanent magnet whose surface portion is configured as an S pole. When the surface portions of each other face each other, they suck each other. Moreover, the polarity of the 2nd case side connection part 52 and the 2nd right side connection part 73b mutually differs, and these 2nd case side connection part 52 and the 2nd right side connection part 73b become a structure which attracts | sucks and mutually connects. ing.

In the above example, the first case side connecting portion 51 has a surface portion configured as an N pole, and the second right connecting portion 73b also has a surface portion configured as an N pole. Sometimes they are repelling each other. In addition, since the second case side connecting portion 52 has a surface portion configured as an S pole, and the first right side connecting portion 73a also has a surface portion configured as an S pole, the surface portion is repelled when the surface portions face each other. It comes to meet each other.

It has a configuration. 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 left side connecting portion 83a is configured as a permanent magnet whose surface portion is configured as an S pole. When the surface portions of each other face each other, they suck each other. Further, the polarities of the second case side connecting portion 52 and the second left side connecting portion 83b are different from each other, and the second case side connecting portion 52 and the second left side connecting portion 83b are sucked and connected to each other. ing. For example, the second case side connecting part 52 is configured as a permanent magnet whose surface part is configured as an S pole, and the second left side connecting part 83b is configured as a permanent magnet whose surface part is configured as an N pole. When the surface portions of each other face each other, they suck each other.

  Further, the first case side connecting portion 51 and the second left side connecting portion 83b have the same polarity, and the second case side connecting portion 52 and the first left side connecting portion 83a have the same polarity. In the above-described example, the first case-side connecting portion 51 has a surface portion configured as an N pole, and the second left connecting portion 83b also has a surface portion configured as an N pole. Sometimes they are repelling each other. Further, the second case side connecting portion 52 has a surface portion configured as an S pole, and the first left side connecting portion 83a also has a surface portion configured as an S pole. Therefore, the second case side connecting portion 52 is repelled when the surface portions face each other. It comes to meet each other.

  Such a guide portion 50 allows the case 12 to be attached to each mounting portion 66, and the orientation of the case 12 (that is, the orientation in the reading direction) is stabilized at the time of attachment. Further, the mounting portion 66 and the guide portion 50 extend at least the front side portion of the case 12 (an extension portion extending forward from the portion supported by the mounting portion 66 in the case 12) from the user's ear. The case 12 can be attached to the user's ear by the configuration.

  Further, the side wall portion (opposing wall portion 12a) on the user side of the case 12 is configured to be fitted to the right fitting portion (surface portion 72) formed in the right mounting portion 70, and the left mounting portion 80. A stepped portion 13 (fitting portion) having a shallow bottom hole shape (specifically, a shape recessed on the inner side of the case) configured to be fitted to the left-side fitting portion (surface portion 82) formed in FIG. When the case 12 is attached to the right mounting portion 70, the step portion 13 (fitting portion) and the right fitted portion (surface portion 72) are fitted, and the case 12 is attached to the left mounting portion 80. When attached, the stepped portion 13 (fitting portion) and the left fitted portion (surface portion 82) are fitted. And two case side connection parts 51 and 52 are arranged at the bottom of the step part 13 having a concave shape, and the surface part 72 or the surface part 82 enters the inside of the recess of the step part 13 during fitting, It is adapted to come into contact with the bottom of the step portion 13. Thereby, not only the position holding by the magnet but also the position holding by fitting is performed, and the case 12 is difficult to be largely displaced at the time of mounting. In particular, the structure is highly effective in suppressing displacement when the first operation unit 42a or the second operation unit 42b is pressed.

  In addition, a plurality of lead-out holes 20 for leading out sound are formed in the wall portion (opposing wall portion 12a) on the side attached to the mounting member 60 in the case 12. The lead-out hole 20 functions as a sound emission hole for leading to the outside the sound emitted from the sound generation unit 44 (speaker or the like: FIG. 2) provided inside the case 12. In this configuration, when the case 12 is attached to the attachment member 60, at least a part (for example, all of the lead-out holes 20) is covered by a covering part (specifically, the surface parts 72 and 82) that forms a part of the attachment member 60. ) Is covered, and when the case 12 is removed from the attachment member 60, the lead hole 20 is exposed at the portion covered by the covering portion when attached. For example, as shown in FIG. 3 and the like, when the case 12 is attached to the right mounting portion 70, the entire surface of the lead-out hole 20 is covered with the surface portion 72 of the right mounting portion 70 so that sound emission is suppressed. It has become. On the other hand, when the attachment state is released and the case 12 is detached from the right side mounting portion 70, the lead hole 20 is exposed at the portion covered by the surface portion 72 when attached. The same applies to the left side, and when the case 12 is attached to the left side mounting part 80, the entire surface of the outlet hole 20 is covered by the surface part 82 of the left side mounting part 80 so that sound emission is suppressed. . On the other hand, when the attachment state is released and the case 12 is detached from the left mounting portion 80, the portion covered by the surface portion 82 at the time of attachment in the lead-out hole 20 is exposed. Note that the position of the two-dot chain line 66a in FIG. 13 is a position that contacts the surface portion 72 or the surface portion 82 when the case 12 is attached to the mounting portion 66 and is covered by the surface portion 72 or the surface portion 82.

  In this configuration, as shown in FIGS. 12 to 14, the apparatus main body 11 can be removed from the attachment member 60, and the apparatus main body 11 can be used or maintained separately from the attachment member 60. And this apparatus main body 11 becomes a structure by which the holding member 90 holding the cable 92 was attached with respect to the case 12, and this holding member 90 can be attached or detached like FIG. 9, FIG. It has become a structure. Further, the holding member 90 is formed with a cable support portion 91 that is fitted to the cable 92 and supports the cable 92. As shown in FIG. 14, the cable 92 is detached from the cable support portion 91 and used. As shown in FIGS. 17 and 20, the cable 92 can be held and used by the cable support portion 91 and can be managed. Further, in this configuration, as shown in FIG. 21, the cable support portion 91 is arranged at a position directly behind the attached portion (the portion held by the attachment member 60 in the case 12), and the cable 92 is connected by the cable support portion 91. Since the moment is held in the vicinity of the center, even if the cable 92 is pulled, the orientation of the case 12 is unlikely to change as indicated by the arrow.

  When the reading device 10 is attached to the user, as shown in FIGS. 18 and 19, the attachment member 60 is first put on both ears of the user, and then, for example, as shown in FIGS. If the apparatus main body 11 is attached to any one of the left mounting portions 80, it can be attached quickly and easily. Further, the present invention is not limited to this method, and the reader 10 may be attached to the user after being assembled as shown in FIG.

  The reading apparatus according to this configuration is not limited to the mounting method and the usage method as shown in FIGS. 3 and 8 and can be used in various usage methods. For example, the external device D (FIG. 22) connected to the cable 92 may be used on the waist as shown in FIG. 3, or may be used by being attached to other parts of the user. For example, the external device D may be used in a trouser pocket.

  Further, in this configuration, as shown in FIG. 22, the cable 92 is detachably attached to the external device D (external device used when reading work is used), and as shown in FIG. It can be connected to an external device PC that is removed from the external device D and different from the external device D. Although there are various functions of the external device D, it may function as a supply source for supplying power to the device body 11, and information from the device body 11 (decoded data when the information code is decoded by the device body 11) May function as a storage medium for storing. Alternatively, a control circuit such as a CPU may be mounted on the external device D, and the code image captured by the imaging unit 23 may be decoded by the external device D.

  Next, the reading process of the information code C by the reading device 10 according to this configuration will be described. The reading device 10 can perform the information code reading process continuously every time a predetermined trigger condition is satisfied or after a predetermined start condition is satisfied. For example, when the operation switch 42 is pressed as a trigger to start imaging, the imaging unit 23 continuously performs imaging processing after the operation switch 42 is pressed, and the information code enters the imaging range of the imaging unit 23 every time. The information code may be read.

  The trigger for starting imaging by the imaging unit 23 is not limited to the above-described method using the operation switch 42. For example, reading may be started on the condition that a predetermined state is detected by a sensor unit 46 different from the operation switch 42. As a specific example, a known proximity sensor that detects the proximity of an object in the forward direction of the case 12 is provided, and imaging is performed by operating the illumination light source 21, the marker light irradiation unit 98, and the imaging unit 23 when the object approaches. An example of performing decryption is given. 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. In this case, this determination process may be performed by the reading device 10 or an external device.

  In the reading device 10, as the reading process starts, the imaging unit 23 continuously captures an imaging range and performs an image capturing process. In this process, a predetermined analysis process is performed on each captured image that is continuously captured, and an attempt is made to recognize one or more types of information codes that are determined in advance. For example, when a known QR code (registered trademark) is scheduled to be read, detection of the position detection pattern is attempted and a contour of the information code is recognized by a known method defined by the QR code. Then, the control circuit 40 performs a known decoding process on the information code C recognized in this way, and decodes the information code C. If the decoding is successful, storage of the decoded decoded data, processing for transmitting the decoded decoded data to an external device, notification of successful decoding, and the like are performed. When decoding fails, a predetermined error notification (for example, error notification by a predetermined buzzer sound) or the like may be performed.

  In this configuration, the control circuit 40 corresponds to an example of a “processing unit”, and is configured to perform predetermined processing on an image captured by the imaging unit 23. In the above-described example, the information code decoding process is exemplified as the “predetermined process” performed by the control circuit 40 corresponding to the “processing unit”, but the predetermined process may be any process for the captured image. For example, it may be a storage process in which an image of an information code is stored in the memory 35, and a decoding result when decoding of the information code is attempted (decoded data obtained by decoding, history data indicating that decoding has failed, etc.) May be stored in the memory 35, or the decoding result may be sounded and notified by the sound generator 44 or the like. Alternatively, the predetermined process may be a process of transmitting a captured image of the information code to an external device away from the case 12, and a process of transmitting the above-described decoding result for the information code to the external device. It may be.

(Setting process)
Next, the setting process performed by the reading device 10 will be described.
In this configuration, the apparatus main body 11 is configured with the configuration in which the above-described imaging unit 23, control circuit 40 (processing unit), and the like are held in the case 12. On the other hand, the attachment member 60 attached to the user's body or the user's attachment is provided as a separate body from the apparatus main body 11 and includes an attachment part 66 (attachment part) to which the apparatus main body 11 is attached and detached. The apparatus main body 11 can be attached to and detached from a plurality of attachment portions (the right attachment portion 70 and the left attachment portion 80). Furthermore, a mounting state detection unit that detects the mounting state of the apparatus main body 11 attached to the mounting unit 66 (attachment unit), and a setting switching unit that switches settings in the apparatus main body 11 based on the detection result of the mounting state detection unit. And are provided. Hereinafter, specific contents of the wearing state detection unit and the setting switching unit will be mainly described.

  As described in the basic configuration, the reading device 10 is provided with a mounting portion 66 as a mounting portion in the mounting member 60 as shown in FIG. 1 and the like, and this mounting portion 66 is a right mounting portion as a first mounting portion. 70 and a left side mounting portion 80 as a second attachment portion. The apparatus main body 11 can be mounted on either the right side mounting part 70 or the left side mounting part 80. In this configuration, as shown in FIG. 24A, when the apparatus main body 11 is attached to the right attachment portion 70 (first attachment portion), a predetermined first attachment state is obtained as shown in FIG. (See also FIG. 5 etc.) When the apparatus main body 11 is attached to the left mounting portion 80 (second attachment portion) as shown in FIG. 25 (A), a predetermined first as shown in FIG. 25 (B). 2 is put on (see also FIG. 7 and the like).

  The apparatus main body 11 includes a predetermined first operation unit 42a in which one or a plurality of first operation areas are configured as a plurality of operation units that can be externally operated, and one or more different from the first operation unit 42a. The second operation part 42b in which the second operation region is configured is provided. In the example shown in FIG. 24, FIG. 25, and the like, the first operation unit 42a in which one operation region is configured by one push button, and the second operation unit in which one operation region is configured by one push button. Although 42b is illustrated, it is not limited to this example. For example, the first operation unit may be configured with a plurality of operation areas configured by a plurality of operation switches, and the second operation unit may be configured with a plurality of operation areas configured by a plurality of operation switches. Good.

  As shown in FIG. 24B, when the apparatus main body 11 is attached to the right attachment part 70 (first attachment part) in the first attachment state, the first operation part 42a becomes the second operation part. It arranges above 42b. Further, as shown in FIG. 25B, when the apparatus main body 11 is mounted in the second mounting state with respect to the left mounting section 80 (second mounting section), the second operation section 42b is replaced with the first operation section. It becomes the structure arrange | positioned above 42a. The first mounting state is a normal mounting state when the apparatus main body 11 is mounted on the right mounting portion 70 (first mounting portion). Specifically, the magnet 51 and the magnet 73a are close to each other. In this state, the magnet 52 and the magnet 73b are attracted to each other while being attracted to each other. The second mounting state is a normal mounting state when the apparatus main body 11 is mounted on the left mounting portion 80 (second mounting portion). Specifically, the magnet 51 and the magnet 83a are attracted while being close to each other. The magnet 52 and the magnet 83b are in close contact with each other.

  On the premise of such a basic configuration, the sensor unit 100 and the control circuit 40 corresponding to the mounting state detection unit are configured so that the mounting state of the apparatus main body 11 attached to the mounting unit 66 (mounting unit) is the first mounting state or the first mounting state. It is detected which of the two wearing states. Specifically, the attachment member 60 is provided with a magnet unit including one or a plurality of magnets (for example, magnets 73a, 73b, 83a, 83b), and the sensor unit 100 including one or a plurality of sensors as an attachment state detection unit. Is provided. In this configuration, the relative positional relationship of the sensor unit 100 with respect to the magnet unit changes according to the mounting state of the apparatus main body 11 with respect to the mounting unit 66 (mounting unit). The mounting state of the apparatus main body 11 is detected based on the magnetic detection result.

  More specifically, as shown in FIG. 24A, the right mounting portion 70 (first mounting portion) is provided with a first magnet portion (for example, a plurality of magnets 73a and 73b) made of one or a plurality of magnets ( As shown in FIG. 25A, the left mounting portion 80 (second mounting portion) is provided with a second magnet portion (for example, a plurality of magnets 83a and 83b) made of one or more magnets. (See also FIG. 10). Then, as shown in FIG. 24B, when the apparatus main body 11 is mounted in the first mounting state with respect to the right mounting portion 70 (first mounting portion), the right mounting portion 70 (first mounting portion). The relative position of the sensor unit 100 with respect to the magnet unit (for example, the plurality of magnets 73a and 73b) disposed in the first position is the first relative position. Specifically, the positional relationship is such that the magnet 73 a is close to the magnetic sensor 101 and the magnet 73 b is close to the magnetic sensor 102. On the other hand, as shown in FIG. 25B, when the apparatus main body 11 is mounted in the second mounting state with respect to the left mounting portion 80 (second mounting portion), the left mounting portion 80 (second mounting portion) The relative position of the sensor unit 100 with respect to the magnet units (for example, the plurality of magnets 83a and 83b) is the second relative position. Specifically, the positional relationship is such that the magnet 83 a is close to the magnetic sensor 101 and the magnet 83 b is close to the magnetic sensor 102. Thus, the arrangement of the magnets close to the sensor unit 100 is different between the first mounting state and the second mounting state, and the influence of magnetism on the sensor unit 100 is different.

  The sensor unit 100 includes a plurality of magnetic sensors 101 and 102, and the sensor unit 100 is configured when the apparatus main body 11 is mounted on the right mounting unit 70 (first mounting unit) in the first mounting state. A first magnetic detection result is obtained by the magnetic sensors 101 and 102. That is, in the magnetic sensor 101, a detection signal greatly influenced by the magnetic force from the magnet 73a is generated, and in the magnetic sensor 102, a detection signal greatly influenced by the magnetic force from the magnet 73b is generated. On the other hand, when the apparatus main body 11 is attached to the left attachment part 80 (second attachment part) in the second attachment state, the second magnetic detection result is obtained by the magnetic sensors 101 and 102 constituting the sensor part 100. can get. That is, in the magnetic sensor 101, a detection signal greatly influenced by the magnetic force from the magnet 83a is generated, and in the magnetic sensor 102, a detection signal greatly influenced by the magnetic force from the magnet 83b is generated. The mounting state detection unit detects the first mounting state when the sensor unit 100 obtains the first magnetic detection result, and detects the second mounting state when the sensor unit obtains the second magnetic detection result. It is configured to detect.

  For example, in this configuration, the magnetic force of the magnet 73a is very large, and the magnetic force of the magnet 73b is significantly smaller than that of the magnet 73a. On the other hand, the magnetic force of the connecting portion 83a is relatively small, and the magnetic force of the connecting portion 83b is significantly larger than that of the connecting portion 83a. In such a configuration, when the apparatus main body 11 is mounted on the right mounting portion 70 as shown in FIG. 24, a large magnetic force is detected by the magnetic sensor 101, and the magnetic sensor 102 detects the amount detected by the magnetic sensor 101. Even a small magnetic force will be detected. On the other hand, when the apparatus main body 11 is mounted on the left mounting portion 80 as shown in FIG. 25, a small magnetic force is detected by the magnetic sensor 101, and the magnetic sensor 102 has a magnetic force larger than the amount detected by the magnetic sensor 101. Will be detected. Therefore, in such a configuration, when the magnetic force detected by the magnetic sensor 102 is larger than the magnetic force detected by the magnetic sensor 101, the control circuit 40 determines that the first wearing state is detected, and the magnetic sensor 101 detects it. When the magnetic force detected by the magnetic sensor 102 is smaller than the applied magnetic force, the control circuit 40 may determine the second mounting state. As described above, the control circuit 40 and the sensor unit 100 corresponding to the mounting state detection unit detect the mounting state of the apparatus main body 11 based on the detection result of the sensor unit 100.

Next, the setting switching process will be described. This setting switching process can be executed by the control circuit 40 using, for example, the detection of either the first mounting state or the second mounting state as a trigger.
The control circuit 40 functions as a setting switching unit and operates to switch the setting in the apparatus main body 11 based on the detection result in the mounting state detection unit. Specifically, when the control circuit 40 functions as a function allocation unit and the first mounting state is detected by the mounting state detection unit, the functions of the plurality of operation units 42a and 42b are set to the first setting, and the mounting state detection unit When the second wearing state is detected, the functions of the plurality of operation units 42a and 42b are set to the second setting.

  For example, when the first wearing state is detected by the wearing state detecting unit by the above-described method, the control circuit 40 corresponding to the function assigning unit assigns the first function to the first operating unit 42a and the second operating unit 42b. A second function is assigned to. There are various examples of the first function, and examples thereof include a function of performing a trigger operation as a trigger for starting imaging. There are various examples of the second function, such as a function of performing a selection operation other than the trigger operation. In this example, it is possible to give a trigger by pressing the first operation unit 42a in the first wearing state, and various selections can be made by pressing the second operation unit 42b. Conversely, a trigger can be given by pressing the second operation unit 42b in the second wearing state, and various selections can be made by pressing the first operation unit 42a.

  The combination of the first function and the second function is not limited to this example. For example, the first function may be a trigger operation input function, and the second function may be a power on / off function. Alternatively, the first function may be a cancel operation input function, and the second function may be a power on / off function or the like. The first function is not limited to one type of operation content, and may be a plurality of functions including, for example, a trigger operation function and a power on / off operation function. Similarly, the second function is not limited to one type of operation content, and may be, for example, a plurality of functions including a selection operation function and various determination functions.

  Note that the memory 35 stores, as setting information, data specifying what function the first function is and what function the second function is, and the first wearing state is detected. In this case, the operation is performed according to the setting information. The setting information can be rewritten by the external device PC when the case 12 is connected to the external device PC such as a computer as shown in FIG.

  On the other hand, when the second wearing state is detected by the wearing state detecting unit, the control circuit 40 corresponding to the function assigning unit assigns the second function to the first operating unit 42a and the first function to the second operating unit 42b. Assign. For example, if the first function is a function that performs the trigger operation described above, this function is realized by the second operation unit 42b. If the second function is a function that performs a selection operation, this function is the first function. This is realized by one operation unit. In this case, it is possible to give a trigger signal by pressing the second operation unit 42b in the second mounting state, and various selections can be made by pressing the first operation unit 42a. In such an example, the first function is executed by the upper operation unit and the second function is executed by the lower operation unit in both the first wearing state and the second wearing state. Even if the configuration is reversed upside down, the vertical relationship of the functions of the operation unit can always be maintained in the same manner.

Furthermore, a mounting state detection unit that detects a mounting state of the device main body 11 attached to the mounting unit, and a setting switching unit that switches settings in the device main body 11 based on the detection result of the mounting state detection unit. Therefore, the setting in the apparatus main body 11 can be switched according to the mounting state. Therefore, compared to a configuration in which the setting is fixed uniformly regardless of the wearing state, the degree of freedom of setting is increased and the convenience for the user is easily improved.

  Specifically, a plurality of operation units 42a and 42b provided in the apparatus main body 11 so as to be externally operable are provided, and the setting switching unit is configured to operate the plurality of operation units 42a and 42b based on the detection result of the mounting state detection unit. 42b has a function assigning unit for assigning a function to each of 42b. According to this configuration, in the configuration including the plurality of operation units 42 a and 42 b, the functions of the plurality of operation units 42 a and 42 b can be set according to the mounting state of the apparatus main body 11.

More specifically, the attachment member 60 is provided with a right attachment portion 70 as a first attachment portion and a left attachment portion 80 as a second attachment portion as attachment portions, and the apparatus body 11 is attached to the right attachment portion 70 ( It is configured to be in a predetermined first mounting state when attached to the first mounting portion), and to be in a predetermined second mounting state when the apparatus main body 11 is attached to the left side mounting portion 80 (second mounting portion). . Then, the mounting state detection unit detects whether the mounting state of the apparatus main body 11 attached to the mounting unit is the first mounting state or the second mounting state, and the function allocation unit performs the first operation by the mounting state detection unit. The functions of the plurality of operation units 42a and 42b are set to the first setting when the mounting state is detected, and the functions of the plurality of operation units 42a and 42b are set to the second setting when the second mounting state is detected by the mounting state detection unit. It is configured to be set.

A second operation unit 42b. When the apparatus main body 11 is attached to the right attachment part 70 (first attachment part) in the first attachment state, the first operation part 42a is disposed above the second operation part 42b, and the apparatus body When 11 is attached to the left attachment part 80 (second attachment part) in the second attachment state, the second operation part 42b is arranged above the first operation part 42a. Further, the function assigning unit assigns the first function to the first operation unit 42a and assigns the second function to the second operation unit 42b when the first wearing state is detected by the wearing state detection unit, and detects the wearing state. When the second mounting state is detected by the unit, the second function is assigned to the first operation unit 42a and the first function is assigned to the second operation unit 42b.
According to this configuration, the apparatus main body 11 is placed in the first mounting state in which the first operation unit 42a is disposed above the second operation unit 42b, and the second operation unit 42b is disposed above the first operation unit 42a. It is possible to switch to and use the second mounted state. On the other hand, in this configuration, the vertical relationship between the first operation unit 42a and the second operation unit 42b is reversed between the first mounting state and the second mounting state, but the operation unit is relatively higher by the function assignment unit. The first function can be assigned to the control unit and the second function can be assigned to the operation unit which is relatively lower. Therefore, in either the first wearing state or the second wearing state, the upper side is used as the first function. The lower side can be used as the second function.

Further, in this configuration, the attachment member 60 is provided with a magnet portion made of one or a plurality of magnets (for example, magnets 73a, 73b, 83a, 83b), and the mounting state detection portion is a sensor portion made of one or more sensors. 100, and the relative positional relationship of the sensor unit 100 with respect to the magnet unit changes according to the mounting state of the apparatus main body 11 with respect to the mounting unit. The mounting state detection unit is configured to detect the mounting state of the apparatus main body 11 based on the detection result of the sensor unit 100.
According to this configuration, the mounting state of the apparatus main body 11 can be detected with a simpler configuration using the magnet unit and the sensor unit 100.

More specifically, the right mounting portion 70 (first mounting portion) is provided with a first magnet portion (for example, a plurality of magnets 73a and 73b) made of one or a plurality of magnets, and the left mounting portion 80 (second mounting portion). Part) is provided with a second magnet part (for example, a plurality of magnets 83a, 83b) made of one or a plurality of magnets. The wearing state detection unit includes a sensor unit 100. When the apparatus main body 11 is attached to the right attachment part 70 (first attachment part) in the first attachment state, a magnet part (for example, a plurality of magnet parts) disposed on the right attachment part 70 (first attachment part) is mounted. The relative position of the sensor unit 100 with respect to the magnets 73a and 73b) is the first relative position, and the apparatus main body 11 is mounted on the left mounting unit 80 (second mounting unit) in the second mounting state.

The mounting state detection unit is configured to detect the mounting state of the apparatus main body 11 based on the detection result of the sensor unit 100.
According to this configuration, the apparatus main body 11 is attached to any of the attachment parts while realizing a configuration in which the attachment position of the apparatus main body 11 can be switched in at least two attachment parts (the first attachment part and the second attachment part). It can be detected with a simpler configuration using the magnet unit (for example, magnets 73a, 73b, 83a, 83b) and the sensor unit 100.

It becomes easy to more accurately detect whether the state is the state based on the magnetic detection result in the sensor unit 100.

[Second Embodiment]
In the second embodiment, only the configuration of the sensor unit and the method for determining the mounting state in the control circuit are different from those of the first embodiment, and other than that is the same as the first embodiment. Therefore, detailed description of the other same parts is omitted, and the same parts as those in the first embodiment shown in the drawings are denoted by the same reference numerals and detailed description thereof is omitted.

  Also in this configuration, the apparatus main body 11 is configured with the configuration in which the imaging unit 23 and the control circuit 40 (processing unit) described above are held while being accommodated in the case 12. On the other hand, the attachment member 60 attached to the user's body or the user's attachment is provided as a separate body from the apparatus main body 11 and includes an attachment part 66 (attachment part) to which the apparatus main body 11 is attached and detached. The apparatus main body 11 can be attached to and detached from a plurality of attachment portions (the right attachment portion 70 and the left attachment portion 80). Furthermore, a mounting state detection unit that detects the mounting state of the apparatus main body 11 attached to the mounting unit 66 (attachment unit), and a setting switching unit that switches settings in the apparatus main body 11 based on the detection result of the mounting state detection unit. And are provided. Hereinafter, specific contents of the wearing state detection unit and the setting switching unit will be mainly described.

  Also in this example, the reading device 10 is provided with a right mounting portion 70 as a first mounting portion and a left mounting portion 80 as a second mounting portion in the mounting member 60, and the apparatus main body 11 is mounted on the right side. It can be mounted on both the portion 70 and the left mounting portion 80. When the apparatus main body 11 is attached to the right attachment part 70 (first attachment part) as shown in FIG. 26A, a predetermined first attachment state is established as shown in FIG. When the apparatus main body 11 is attached to the left attachment portion 80 (second attachment portion) as shown in (A), a predetermined second attachment state is obtained as shown in FIG.

  Also in this example, the apparatus main body 11 includes a predetermined first operation unit 42a in which one or a plurality of first operation areas are configured as a plurality of operation units that can be externally operated, and the first operation unit 42a. There is provided a second operation unit 42b in which one or a plurality of different second operation areas are configured. As shown in FIG. 26B, when the apparatus main body 11 is attached to the right attachment part 70 (first attachment part) in the first attachment state, the first operation part 42a becomes the second operation part. When the apparatus main body 11 is mounted in the second mounting state with respect to the left mounting portion 80 (second mounting portion) as shown in FIG. 27B, the second operation portion is disposed above 42b. 42b is arranged above the first operation portion 42a.

  On the premise of such a basic configuration, the sensor unit 200 and the control circuit 40 corresponding to the mounting state detection unit are configured so that the mounting state of the apparatus body 11 attached to the mounting unit 66 (mounting unit) is the first mounting state or the second mounting state. Detect which of the states. Even in this configuration, the attachment member 60 is provided with a magnet portion including one or a plurality of magnets (for example, magnets 73a, 73b, 83a, and 83b), and the sensor portion 200 is provided as the mounting state detection portion. And since the relative positional relationship of the sensor part 200 with respect to a magnet part changes according to the mounting state of the apparatus main body 11 with respect to the mounting part 66 (attachment part), a mounting state detection part is a detection result in the sensor part 200. Based on this, the mounting state of the apparatus main body 11 is detected.

  More specifically, as shown in FIG. 26A, the right mounting portion 70 (first mounting portion) is provided with a first magnet portion (for example, a plurality of magnets 73a and 73b) made of one or a plurality of magnets ( As shown in FIG. 27A, the left mounting portion 80 (second mounting portion) is provided with a second magnet portion (for example, a plurality of magnets 83a and 83b) made of one or more magnets. (See also FIG. 10). As shown in FIG. 26B, when the apparatus main body 11 is mounted in the first mounting state with respect to the right mounting portion 70 (first mounting portion), the right mounting portion 70 (first mounting portion). The relative position of the sensor unit 200 with respect to the magnet unit (for example, the plurality of magnets 73a and 73b) disposed in the first position is the first relative position. Further, as shown in FIG. 27B, when the apparatus main body 11 is attached to the left attachment portion 80 (second attachment portion) in the second attachment state, the left attachment portion 80 (second attachment portion) is attached. The relative position of the sensor unit 200 with respect to the magnet unit to be arranged (for example, the plurality of magnets 83a and 83b) is the second relative position. Thus, the arrangement of the magnets close to the sensor unit 200 is different between the first mounting state and the second mounting state, and the influence of magnetism on the sensor unit 200 is different.

  The sensor unit 200 includes a plurality of induced current generation units 201 and 202. The induced current generators 201 and 202 are circuits that generate an induced current according to the proximity or separation of the magnets. In this configuration, when the apparatus main body 11 is mounted on the right mounting section 70 (first mounting section) in the first mounting state, the induced current generating sections 201 and 202 are in the first current state, and the apparatus main body 11 is on the left side. When the mounting portion 80 (second mounting portion) is mounted in the second mounting state, the induced current generating units 201 and 202 are in the second current state. Specifically, the magnetic force of the magnet 73a is very large, and the magnetic force of the magnet 73b is significantly smaller than that of the magnet 73a. On the other hand, the magnetic force of the connecting portion 83a is relatively small, and the magnetic force of the connecting portion 83b is significantly larger than that of the connecting portion 83a. In such a configuration, when the apparatus main body 11 is mounted on the right mounting unit 70 as shown in FIG. 26, the amount of current generated by the induced current generating unit 201 becomes large, and the current generated by the induced current generating unit 202 The amount is smaller than that. On the other hand, when the apparatus main body 11 is mounted on the left mounting portion 80 as shown in FIG. 27, the amount of current generated by the induced current generating unit 201 becomes smaller and the amount of current generated by the induced current generating unit 202 is smaller than that. Also grows. Therefore, in such a configuration, when the amount of current generated by the induced current generating unit 201 is larger than the amount of current generated by the induced current generating unit 202 (in the first current state), the control circuit 40 performs the first mounting. When the amount of current generated by the induced current generating unit 201 is smaller than the amount of current generated by the induced current generating unit 202 (in the case of the second current state), the control circuit 40 determines that the current state is the second wearing state. do it. As described above, the control circuit 40 and the sensor unit 200 corresponding to the mounting state detection unit detect the mounting state of the apparatus main body 11 based on the detection result of the sensor unit 200.

  As described above, in this configuration, the apparatus main body 11 can be switched to any mounting portion while realizing a configuration in which the mounting position of the device main body 11 can be switched in at least two mounting portions (the first mounting portion and the second mounting portion). It can be more easily detected whether it is in the attached state based on the current state in the induced current generation units 201 and 202.

[Third Embodiment]
Next, a third embodiment will be described with reference to FIGS.
In the third embodiment, only the configuration of the sensor unit and the method for determining the mounting state in the control circuit are different from those of the first embodiment, and other than that is the same as the first embodiment. Therefore, detailed description of the other same parts is omitted, and the same parts as those in the first embodiment shown in the drawings are denoted by the same reference numerals and detailed description thereof is omitted.

  In this configuration, the sensor unit 300 and the control circuit 40 constitute a mounting state detection unit. The sensor unit 300 is configured as one or a plurality of press detection units (specifically, the shaft unit 301 and the pressure sensor 303), and the mounting unit 66 (attachment unit) includes a press detection unit (specifically, Is formed with a detected part 310 having a pressing part 312 capable of pressing the shaft part 301) forming a part of the pressing detection part and a retracting part 311 for retracting so as to reduce the pressing state of the pressing detection part. .

  Specifically, as shown in FIG. 30A, a retracting portion 311 configured as a hole is formed near the center of the magnet 73a, and the apparatus main body 11 is attached to the right mounting portion 70 (first mounting portion). When the sensor unit 300 is mounted in the first mounting state, the position of the detected part 310 with respect to the sensor unit 300 is the first relative position as shown in FIG. Is obtained. At this first relative position, a part of the shaft portion 301 that constitutes the sensor unit 300 (pressing detection unit) enters the retreating portion 311, so that the pressure applied to the pressure sensor 303 by the shaft portion 301 becomes relatively small. . On the other hand, when the apparatus main body 11 is attached to the left attachment part 80 (second attachment part) in the second attachment state, the position of the detected part 310 relative to the sensor part 300 is as shown in FIG. The second relative position is obtained, and the second press detection result is obtained by the sensor unit 300. In this configuration, the retraction part 311 is not formed near the magnet 83a, and the shaft part 301 constituting the sensor part 300 (press detection part) is pushed by the pressing part 312 at the first relative position. Therefore, the pressure applied to the pressure sensor 303 by the shaft portion 301 is relatively increased.

  The wearing state detection unit detects the first wearing state when the first press detection result is obtained by the sensor unit 300, and the second wearing state when the second press detection result is obtained by the sensor unit 300. Is detected. The first pressure detection result is, for example, a result that the pressure detected by the pressure sensor 303 is equal to or lower than a predetermined threshold, and the second pressure detection result is, for example, the result that the pressure detected by the pressure sensor 303 exceeds a predetermined threshold. It is. The setting in the apparatus main body 11 when the first mounting state is detected and the setting in the apparatus main body 11 when the second mounting state is detected are the same as in the first embodiment.
