Description

This invention relates to an optical information reading device that optically reads optical information such as information codes.

In recent years, concerns about viral infections have increased, and the spread of infection within healthcare facilities, in particular, has become a major problem. Optical information reading devices such as barcode readers used in medical settings can also potentially become carriers of bacterial and viral infections. Therefore, for reading devices used in medical settings, it is necessary to perform wipe-down disinfection, at least on the gripping part that the user holds, to prevent infection and maintain cleanliness.

Japanese Patent Application Publication No. 06-251180

Incidentally, in optical information reading devices that are equipped with a trigger switch or the like that is pressed to start the reading process, the trigger switch or the like is configured to be exposed from the housing that constitutes the outer casing. In such a configuration, since the operating part of the trigger switch or the like is a driven mechanism, wiping away bacteria and viruses from the driving part takes time, and there is a problem that the wiping and disinfection will be insufficient. Furthermore, even if the driving part is eliminated by providing touch electrodes on both sides of the housing to detect when the user's finger touches it, as in the barcode reader disclosed in Patent Document 1, grooves or steps are formed between the outer edges of the touch electrodes exposed from both sides and the surrounding housing, so the aforementioned problem of wiping and disinfection cannot be fully solved.

This invention was made to solve the above-mentioned problems, and its objective is to provide a configuration that allows for easy wiping and disinfection of the gripping portion on which the operating means are provided.

To achieve the above objective, the invention described in claim 1 of the claims is:
A reading unit (41, 43) that optically reads optical information (C),
A housing (11) that forms a housing space for housing the reading unit by assembling multiple cases (20, 30),
An optical information reading device (10, 10a to 10c) comprising,
A gripping portion (31) that is held by the user is formed as part of the housing,
The gripping portion is provided with a predetermined operating surface (34) that the user touches when starting a predetermined process related to the reading portion, and a detection unit (45) is provided at a position on the inner side of the gripping portion relative to the predetermined operating surface to detect when the predetermined operating surface is being touched .
The reading unit optically reads the optical information through a reading opening formed in the housing.
The housing is provided with an extension that extends from between the lower edge of the reading opening on the gripping side and the gripping part, in the direction toward the reading opening.
The optical information reading device is characterized in that, when placed on a predetermined surface with the upper edge of the reading opening and the tip edge of the extension facing downwards, the position of each component within the housing is adjusted such that the center of gravity of the optical information reading device projected onto the predetermined surface falls within the range enclosed by the contact area between the upper edge and the predetermined surface and the contact area between the tip edge and the predetermined surface .
The symbols within the parentheses above indicate the correspondence with the specific means described in the embodiments described later.

In the inventions of claims 1 , 2, and 4 , a gripping portion that is held by the user is formed as part of the housing, the gripping portion is provided with a predetermined operating surface that the user touches when starting a predetermined process related to the reading portion, and a detection unit is provided at a position on the inner side of the gripping portion relative to the predetermined operating surface for detecting when the predetermined operating surface is being touched.

This allows the detection unit to be used as an operating means by the user, and since the detection unit is located on the inner surface of the gripping part, the predetermined operating surface and its surroundings can be constructed solely from the outer surface of the housing, which is free of grooves, steps, and other irregularities. Therefore, an optical information reading device can be realized that allows for easy wiping and disinfection of the gripping part on which the operating means is provided.

In the invention of claim 4 , the gripping portion is formed by one of the multiple cases in a part where there are no joints between the cases. As a result, the joints between the cases can be eliminated from the gripping portion, making it easier to wipe and disinfect the gripping portion.

In the invention of claim 4 , the detection unit is composed of a piezoelectric sensor capable of detecting strain occurring on a predetermined operating surface. This allows the user to press the predetermined operating surface with their finger even while holding the gripping part, thereby improving work efficiency for tasks such as reading.

In the invention of claim 4 , the thickness of the case of the part constituting a predetermined operating surface is formed to be thinner than the thickness of the case of the other parts. As a result, the detection unit can more easily detect when the predetermined operating surface is being touched, thereby improving the detection accuracy of the detection unit, i.e., the operability of the device.

In the invention of claim 6, a vibrating part is provided at a position on the inner side of the gripping part relative to a predetermined operating surface. This vibrates to a predetermined state when the detection unit detects that the predetermined operating surface is being touched. As a result, when the user touches the predetermined operating surface to initiate the predetermined process, the vibrating part vibrates to the predetermined state, allowing the user to obtain a tactile sensation corresponding to that vibration.

In the invention of claim 7, a magnet is provided on the mounting surface of the mounting platform on which the optical information reading device is placed, and a magnet is also provided at a position on the inner surface of the housing that faces the mounting surface when the device is placed. As a result, when the optical information reading device is placed on the mounting platform, the magnet on the mounting surface and the magnet on the inner surface of the housing attract each other and secure the device. This eliminates the need for uneven surfaces or other features to engage and secure the optical information reading device to the mounting platform, making it easy to wipe and disinfect the area on the mounting platform where the device is placed.

In the invention of claim 8, since the part of the housing facing the mounting surface is not a gripping part, the gripping part does not come into contact with the mounting base during mounting, thus allowing the gripping part to be kept cleaner.

In the invention of claim 9, the predetermined operating surface is formed such that its central portion protrudes outward relative to its outer periphery, and the detection unit is configured to detect distortion occurring in the outer periphery. This makes it easier for the finger to contact the predetermined operating surface at its central portion during operation, compared to the case where the predetermined operating surface is formed in a flat shape. Furthermore, even though the central portion protrudes outward, the detection unit can detect distortion occurring in the outer periphery, so the detection accuracy does not decrease.

In the invention of claim 10, the housing is provided with a projection that protrudes inward at a position on the inner side of the central part of a predetermined operating surface, and the detection unit is configured to detect the strain occurring on the predetermined operating surface according to the amount of inward deformation of the projection. Since the central part deforms the most when the predetermined operating surface is touched, the amount of inward movement of the projection located on the inner side of this central part can be increased, thereby improving the detection accuracy of the detection unit, i.e., the operability of the device.

In the invention of claim 1 , the housing is provided with an extension that extends from between the lower edge of the reading opening on the gripping side and the gripping part in the direction toward the reading opening. The positions of the components within the housing are adjusted so that when the optical information reading device is placed on a predetermined surface with the upper edge of the reading opening and the tip edge of the extension facing downwards, the center of gravity of the optical information reading device projected onto this predetermined surface falls within the range enclosed by the contact area between the upper edge and the predetermined surface and the contact area between the tip edge and the predetermined surface. As a result, the optical information reading device can be placed on a desk or the like with the upper edge of the reading opening and the tip edge of the extension facing downwards, depending on the extension length of the extension, and in this placed state, the gripping part does not come into contact with the desk or the like, so the gripping part can be kept cleaner.

In the invention of claim 11 , the housing is formed with sound-emitting holes for releasing a predetermined sound emitted by a sound-producing unit provided inside the housing to the outside, and the double-sided tape used to adhere a sheet to the housing to close the sound-emitting holes has an opening larger than the sound-emitting holes. As a result, even when a sheet is adhered to the housing using double-sided tape to close the sound-emitting holes in order to maintain cleanliness, the double-sided tape does not cover the sound-emitting holes, so the reduction in sound pressure of the predetermined sound released to the outside can be suppressed compared to the case where the double-sided tape also covers the sound-emitting holes.

The invention of claim 12 is provided with a notification unit that notifies cleaning instruction information prompting cleaning of the optical information reading device at a predetermined timing. This not only makes it easier to perform the cleaning work at an appropriate timing, but also helps prevent the cleaning work from being forgotten.

In the invention of claim 13 , the notification unit notifies cleaning instruction information upon receiving instructions from a higher-level terminal, so the higher-level terminal can easily adjust the timing of notifying the cleaning instruction information.

In the invention of claim 14 , worker information identifying the worker who performed the cleaning work is acquired by the acquisition unit, and this acquired worker information is stored in the storage unit along with information related to the cleaning work. As a result, not only can work history and the like be easily managed based on the information stored in the storage unit, but the timing of notifying the cleaning instruction information can also be easily adjusted to match the actual work situation.

In the invention of claim 15 , the detection result of the cleaning work detection unit, which can detect when cleaning work has been performed on the optical information reading device, is stored in the storage unit. This makes it possible to record a more reliable work history and to adjust the timing of notifying the cleaning instruction information according to the actual situation.

In the invention of claim 16 , at least a portion of the information stored in the storage unit is transmitted to a higher-level terminal, and the notification unit notifies cleaning instruction information upon receiving instructions from the higher-level terminal. As a result, the higher-level terminal can easily grasp the work history related to the optical information reading device under management, and can appropriately adjust the timing of notifying the cleaning instruction information in accordance with the actual work situation.

In the invention of claim 17 , when patient information identifying the patient is read from optical information by the reading unit, the patient's body temperature is measured by the body temperature measurement unit, and the determination unit determines whether or not the patient has a fever based on the measurement result from the body temperature measurement unit. As a result, not only can the patient's body temperature be measured with an optical information reading device that allows for easy wiping and disinfection, but it is also possible to easily determine whether or not the patient has a fever, thereby reducing the burden on nursing care for the patient.

In the invention of claim 2 , the housing is provided with an extension portion that extends in a thin plate shape from between the lower edge on the gripping side of the reading opening and the gripping portion, in the direction toward the reading opening, and a coil for wireless power transmission is arranged within this extension portion. In this way, since the coil for wireless power transmission is arranged within the extension portion that extends in a thin plate shape, the heat generated in the coil during power transmission is dissipated from the surface of the extension portion on the reading opening side and the surface on the gripping portion side, respectively. As the extension length of the extension portion increases, the heat dissipation area by the surface on the reading opening side and the surface on the gripping portion side increases, so the heat dissipation performance of the heat generated by the coil for wireless power transmission can be improved according to the extension length of the extension portion.

In the invention of claim 3 , the coil for wireless power transmission is bonded to the inner surface of the housing portion constituting the extension, which is on the reading side. When power is supplied by placing the gripping side surface of the extension (hereinafter also referred to as the mounting side) on the charging surface of the charger, the mounting side has poor heat dissipation due to its proximity to the charging surface, while the heat dissipation of the reading side surface of the extension (hereinafter also referred to as the anti-mounting side) is not affected by the charging surface. Therefore, by bonding the coil for wireless power transmission to the inner surface of the housing portion constituting the extension, which is on the reading side, the heat generated in the coil for wireless power transmission during charging is more easily transferred to the anti-mounting side, which has better heat dissipation, thus further improving the heat dissipation effect of the thin plate-shaped extension.

[First Embodiment]
A first embodiment of the optical information reading device of the present invention will be described below with reference to the drawings.
The optical information reading device 10 according to this embodiment is configured as a portable reading device that optically reads optical information such as information codes (for example, barcodes and QR codes (registered trademarks)).

As shown in Figures 1 to 4, the housing 11 constituting the outer casing of the optical information reading device 10 is configured to form a housing space for various electronic components by assembling an upper case 20 in which the reading opening 21 is formed and a lower case 30 in which a gripping portion 31, which is held by the user, is formed. The upper case 20 is provided with a guide 22 extending in the direction in which the reading opening 21 faces (hereinafter also referred to as the forward or front direction) to facilitate the orientation of the reading opening 21 towards the information code. The upper surface of this guide 22 is parallel to the combined surface of the upper case 20 and the lower case 30.

The lower case 30 is formed so that the assembly portion 32, which is assembled below the upper case 20 such as the guide 22, and the gripping portion 31, which constitutes the portion of the lower case 30 below the assembly portion 32, are integrated. The gripping portion 31 is formed without grooves or other features on its outer surface to facilitate wiping and disinfection, and the connection portion with the assembly portion 32 is also formed to be smoothly curved.

An operating base 33 is provided on the gripping portion 31, located below the guide 22 and at a position accessible to the fingers while gripping the gripping portion 31, so as to protrude smoothly forward. This operating base 33 is configured such that its flat front surface functions as an operating surface 34 that deforms when pressed (hereinafter also referred to as the reading start operation) to initiate the reading process for reading information codes. Specifically, to make the operating surface 34 easily deformable, the operating base 33 is formed such that the thickness (wall thickness) t of the lower case 30 of the part constituting the operating surface 34 is thinner than the thickness of the lower case 30 of the other parts. For example, if the thickness of the lower case 30 of the other parts is approximately 1.5 to 2 mm, the thickness t of the lower case 30 of the part constituting the operating surface 34 is approximately 0.7 to 1.5 mm.

Next, the electrical configuration of the optical information reading device 10 will be explained with reference to the drawings.
As shown in Figure 5, the optical information reading device 10 includes a control unit 41 consisting of a CPU, a storage unit 42 consisting of ROM, RAM, non-volatile memory, etc., an imaging unit 43 configured as a camera equipped with a light receiving sensor (e.g., a C-MOS area sensor, a CCD area sensor, etc.), an illumination unit 44 that irradiates illumination light toward the imaging field of view of the imaging unit 43, a detection unit 45 that detects a reading start operation on the operating surface 34, a communication unit 46 configured as a communication interface for wireless communication with external devices such as a mounting base 100 such as a cradle or a higher-level terminal 1 such as a management server, and a buzzer 47 capable of emitting buzzer sounds such as beeps and alarms. At least some of these various electronic components are housed in a housing space formed by the upper case 20 and lower case 30 of the housing 11. For example, the imaging unit 43 and the illumination unit 44 are housed in the upper case 20 such that the imaging unit 43 has an imaging range in front of it via the reading opening 21, and the illumination unit 44 irradiates illumination light toward the imaging field of view via the reading opening 21.

The detection unit 45 is a piezoelectric sensor (piezoelectric element sensor) for detecting strain occurring in the operating surface 34. As shown in Figure 6, it is positioned on the inner side of the gripping portion 31 relative to the operating surface 34, and is supported (clamped) by the support plate 35. The detection unit 45 is configured to output a predetermined operation detection signal to the control unit 41 when the strain of the operating surface 34 exceeds a predetermined value, indicating that a reading start operation has been performed.

Specifically, for example, as shown in Figure 7(A), if the distortion detected by the detection unit 45 is less than a predetermined value because the operating surface 34 is not distorted, the operation detection signal is not output to the control unit 41, as it is assumed that a reading start operation has not been performed on the operating surface 34. On the other hand, as shown in Figure 7(B), if the distortion detected by the detection unit 45 is greater than or equal to the predetermined value because the operating surface 34 is distorted by a predetermined amount or more, the operation detection signal is output to the control unit 41, as it is assumed that a reading start operation (see arrow F in Figure 7(B)) has been performed on the operating surface 34. Note that, for convenience, in Figures 7(A) and (B), the parts housed on the inner surface of the gripping portion 31 are omitted from the illustration, except for the detection unit 45.

The control unit 41, upon receiving the detection signal from the detection unit 45, initiates a reading process using the captured image of the information code C (see Figure 5) captured by the imaging unit 43. This reading process decodes the data recorded in the information code C using a predetermined decoding method. The reading results obtained through this reading process are wirelessly transmitted to a higher-level terminal via the communication unit 46 at a predetermined timing. The control unit 41, together with the imaging unit 43, corresponds to an example of a "reading unit" that optically reads optical information such as the information code C, and is housed in the housing space formed by the casing 11.

As described above, in the optical information reading device 10 according to this embodiment, the gripping portion 31, which is held by the user, is formed as part of the lower case 30 that constitutes the housing 11. The gripping portion 31 is provided with an operating surface 34 that the user touches when starting the reading process, and a detection unit 45 is provided at a position on the inner side of the gripping portion 31 relative to the operating surface 34 to detect when the operating surface 34 is being touched.

This allows the detection unit 45 to be used as an operating means by the user, and since the detection unit 45 is provided on the inner surface of the gripping unit 31, the operating surface 34 and its surroundings can be constructed solely from the outer surface of the lower case 30, which is free of grooves, steps, etc. Therefore, an optical information reading device can be realized that allows for easy wiping and disinfection of the gripping unit 31 where the operating means is provided.

In particular, the gripping portion 31 is formed in a location where there are no joints between the cases, as determined by the lower case 30. This eliminates the joints between the cases from the gripping portion 31, making it easier to perform wipe-cleaning and disinfection of the gripping portion 31.

Furthermore, since the detection unit 45 is composed of a piezoelectric sensor capable of detecting distortion occurring on the operating surface 34, the user can press the operating surface 34 with their finger even while holding the gripping unit 31, thereby improving the efficiency of tasks such as reading.

Furthermore, the detection unit 45 is not limited to being composed of a piezoelectric sensor; it may also be composed of other detection means capable of detecting when the operating surface 34 is being touched, such as a capacitive sensor capable of detecting changes in capacitance occurring on the operating surface 34. When the detection unit 45 is composed of a capacitive sensor in this way, there is no need to form the gripping portion 31 and housing 11 so that the operating surface 34 deforms to a predetermined state due to user operation. Therefore, variations in dimensional accuracy required for the gripping portion 31 and housing 11 can be reduced.

Furthermore, the thickness t of the lower case 30 of the part constituting the operating surface 34 is formed to be thinner than the thickness of the lower case 30 constituting the other parts (see Figure 7). This makes it easier for the detection unit 45 to detect when the operating surface 34 is being touched, thereby improving the detection accuracy of the detection unit 45, and thus the operability of the device.

Furthermore, the operating surface 34 on the inner side of the detection unit 45 is not limited to being a flat surface located in front of the gripping unit 31; for example, it may be configured as a curved surface located in front of the gripping unit 31. Also, the operating surface 34 may be provided on one of the left-right surfaces perpendicular to the front-rear direction of the gripping unit 31, as exemplified by the lower case 30a of the optical information reading device 10a in Figure 8. This one surface may be configured as a curved surface, or it may be formed as a smoothly protruding flat surface, such as the operating base 33.

Furthermore, the operating surfaces 34 may be provided on each of the left and right surfaces of the gripping portion 31. In this case, where a pair of operating surfaces 34 are provided on the left and right sides of the gripping portion 31, the detection unit 45 can detect when the fingers holding the gripping portion 31 touch each operating surface 34, thereby indicating the start of the reading operation.

[Second Embodiment]
Next, an optical information reading device according to a second embodiment of the present invention will be described with reference to the drawings.
This second embodiment differs from the first embodiment in that it provides the user with a tactile sensation during operation. Therefore, components that are substantially the same as those in the first embodiment are denoted by the same reference numerals, and their descriptions are omitted.

As shown in Figure 9, in this embodiment, a vibration actuator 51 is provided at a position on the inner side of the gripping portion 31 relative to the operating surface 34. When the detection unit 45 detects that the operating surface 34 is being touched, a vibration actuator 51 is provided that vibrates to a predetermined state in accordance with the control unit 41.

As a result, when the user touches the operating surface 34 to initiate the reading process, the vibration actuator 51 vibrates to a predetermined state, allowing the user to experience a tactile sensation corresponding to the vibration. The vibration actuator 51 may be configured to vibrate using, for example, an ERM (Electromagnetic Resonance) method, an LRA (Laser Raising) method, or a piezoelectric method.

Furthermore, the characteristic configuration of this embodiment, which provides a tactile sensation through the vibration actuator 51, can be applied to other embodiments as well.

[Third Embodiment]
Next, an optical information reading device according to a third embodiment of the present invention will be described with reference to the drawings.
This third embodiment differs from the first embodiment in that magnets are used to fix the device to the mounting base in order to facilitate the wiping and disinfection process. Therefore, components that are substantially the same as those in the first embodiment are denoted by the same reference numerals, and their descriptions are omitted.

When a portable reader or similar device is placed on a charging base such as a cradle, it is conceivable to provide interlocking grooves or other protrusions on both the reader/device and the base to secure it in place. However, the presence of these grooves or protrusions makes wiping and disinfecting the device time-consuming, posing a problem in that it cannot be easily performed.

Therefore, as shown in Figure 10, on the mounting table 100a on which the optical information reading device 10b according to this embodiment is placed, a magnet 102 is provided at a position on the inner surface side of the mounting surface 101. Furthermore, on the optical information reading device 10b, a magnet 52 is provided at a position on the inner surface side of the part of the housing 11 that faces the mounting surface 101 when the device is mounted. In this embodiment, an extension portion 12 is formed by the guide 22 of the upper case 20 and the forward-extending portion of the assembly portion 32 in the lower case 30. This extension portion 12 is a portion that extends in a substantially thin plate shape from between the lower edge of the reading opening 21 on the gripping portion side and the gripping portion 31 in the direction toward the reading opening 21, and is the part of the housing 11 that faces the mounting surface 101 when mounted. The magnet 52 is provided at a position on the inner surface side of this extension portion 12.

As a result, when the optical information reading device 10b is placed on the mounting base 100a, the magnet 102 on the mounting surface 101 and the magnet 52 on the extension 12 attract each other, fixing them in place. Therefore, the need for protrusions or other irregularities to engage and fix the optical information reading device 10b to the mounting base 100a is eliminated, making it easier to wipe and disinfect the area on the mounting base 100a where the device is placed.

In particular, as can be seen from Figure 10, the portion of the housing 11 that faces the mounting surface 101 during placement is the extension portion 12, not the gripping portion 31. Therefore, the gripping portion 31 does not come into contact with the mounting base 100a during placement, allowing the gripping portion 31 to be kept cleaner.

Furthermore, the magnet 52 used for mounting and fixing is not limited to being positioned on the inner surface of the extension portion 12; it may also be positioned on the inner surface of the portion of the housing 11 facing the mounting surface when placed on the mounting base.

Furthermore, the characteristic configuration of this embodiment, which utilizes a magnet 52 for mounting and fixing, can also be applied to other embodiments.

[Fourth Embodiment]
Next, an optical information reading device according to a fourth embodiment of the present invention will be described with reference to the drawings.
This fourth embodiment differs from the first embodiment in that a predetermined operating surface is formed to facilitate contact with the user's fingers during operation. Therefore, components that are substantially the same as those in the first embodiment are denoted by the same reference numerals, and their descriptions are omitted.

As shown in Figure 11(A), the operating surface 34a according to this embodiment is formed such that its central portion 34b protrudes outward relative to the outer peripheral portion 34c. The detection unit 45 according to this embodiment is configured, for example, by a piezoelectric sensor, to detect strain occurring in the outer peripheral portion 34c.

This makes it easier for the finger to contact the operating surface 34a at its central portion 34b during operation, compared to when the operating surface 34 is formed in a flat shape. Furthermore, even if the central portion 34b protrudes outward, the detection unit 45 can detect the distortion occurring in the outer peripheral portion 34c, thus preventing a decrease in detection accuracy.

Furthermore, as a modification of this embodiment, the operating surface 34a may be provided on each of the left and right surfaces perpendicular to the front-rear direction of the gripping portion 31, as illustrated in Figure 11(B). Alternatively, the operating surface 34a may be provided on one of the left and right surfaces perpendicular to the front-rear direction of the gripping portion 31.

Furthermore, the characteristic configuration of this embodiment, in which the operating surface 34a is formed such that the central portion 34b protrudes outward relative to the outer peripheral portion 34c, can also be applied to other embodiments.

[Fifth Embodiment]
Next, an optical information reading device according to a fifth embodiment of the present invention will be described with reference to the drawings.
In this fifth embodiment, the center of gravity is adjusted so that the gripping portion 31 can be placed facing upwards, which is the main difference from the first embodiment. Therefore, components that are substantially the same as those in the first embodiment are denoted by the same reference numerals, and their descriptions are omitted.

When a portable reader or similar device is placed on a designated surface such as a desk surface S, a portion of the gripping part may come into contact with the desk surface S and become soiled.

Therefore, in this embodiment, the optical information reading device 10 is designed to be placed on a desk surface S with the gripping portion 31 facing upwards. The center of gravity G is adjusted to allow placement on the desk surface S by utilizing the extension portion 12 that extends from between the lower edge of the reading opening 21 (the gripping portion side) and the gripping portion 31 in the direction the reading opening 21 faces.

Specifically, as shown in Figures 12 and 13, in this embodiment, when the optical information reading device 10 is placed on the desk surface S with the upper edge 21a of the reading opening 21 and the tip edge 12a of the extension portion 12 facing downwards, the positions of the various electronic components within the housing 11 are adjusted so that the center of gravity G of the optical information reading device 10 projected onto the desk surface S falls within the area enclosed by the contact points between the upper edge 21a and the desk surface S and the contact points between the tip edge 12a and the desk surface S (see reference numeral L1 in Figure 12 and reference numeral L2 in Figure 13).

This allows the optical information reading device 10 to be placed on the desk surface S with the upper edge 21a of the reading opening 21 and the tip edge 12a of the extension 12 facing downwards. In this placement, the gripping portion 31 does not come into contact with the desk surface S, thus allowing the gripping portion 31 to be kept cleaner.

In particular, in this embodiment, the extension length of the extension portion 12 is set such that, in the above-described position, the extension direction of the gripping portion 31 relative to the desk surface S is approximately 45°. This not only improves the stability of the posture in the above-described position, but also makes it easier to grasp the gripping portion 31 from that position.

Furthermore, the characteristic configuration of this embodiment, which adjusts the center of gravity G so that the gripping portion 31 can be placed with the gripping portion facing upwards, can also be applied to other embodiments.

[Sixth Embodiment]
Next, an optical information reading device according to a sixth embodiment of the present invention will be described with reference to the drawings.
This sixth embodiment differs from the first embodiment in that the sound emission holes are closed to suppress a decrease in the sound pressure of the buzzer sound emitted to the outside. Therefore, components that are substantially the same as those in the first embodiment are denoted by the same reference numerals, and their descriptions are omitted.

As shown in Figure 14, the upper case 20 of the housing 11 has a sound vent 13 formed therein for emitting the buzzer sound emitted by the buzzer 47 located inside the housing 11 to the outside. To maintain cleanliness, this sound vent 13 is sealed by a sheet material such as a PET sheet (hereinafter also simply referred to as sheet 53) attached to the upper case 20 using double-sided tape 54. The buzzer 47 can be considered an example of a "sound-producing unit" located inside the housing 11 that emits a buzzer sound at a predetermined pitch.

In this embodiment, to suppress the decrease in sound pressure of the buzzer sound emitted to the outside through the sound emission hole 13, an opening 54a larger than the sound emission hole is formed in the double-sided tape 54, as shown in Figure 15.

This means that even when the sheet 53 is attached to the housing 11 using double-sided tape 54 to cover the sound vent 13, the double-sided tape 54 does not cover the sound vent 13. Therefore, compared to the case where the double-sided tape also covers the sound vent 13, the reduction in the sound pressure of the buzzer sound can be suppressed.

Furthermore, the characteristic configuration of this embodiment, in which an opening 54a larger than the sound-emitting hole 13 is formed in the double-sided tape 54 used to adhere the sheet 53, can also be applied to other embodiments.

[Seventh Embodiment]
Next, an optical information reading device according to a seventh embodiment of the present invention will be described with reference to the drawings.
This seventh embodiment differs from the first embodiment in that it provides a predetermined notification to prevent forgetting cleaning tasks such as wiping and disinfecting. Therefore, components that are substantially the same as those in the first embodiment are denoted by the same reference numerals, and their descriptions are omitted.

While cleaning tasks such as wiping and disinfecting the optical information reading device 10 need to be performed regularly, it is also necessary to prevent these tasks from being forgotten.

Therefore, in this embodiment, assuming that information regarding the cleaning work schedule is pre-stored in the storage unit 42, cleaning instruction information prompting the cleaning work is notified at a predetermined timing corresponding to that work schedule. This cleaning instruction information can be notified audibly using the buzzer sound of the buzzer 47 or voice guidance from a speaker (not shown in the figure). Furthermore, the cleaning instruction information may be notified visually, for example, using the LED 47a provided on the upper case 20, as illustrated in Figure 16, or using vibration from the vibration actuator (vibration unit) 51 or light emission from LEDs belonging to the lighting unit 44. Also, the cleaning instruction information may be notified at the time when the cleaning work should begin, or it may be notified at a predetermined time after the cleaning work should begin. The buzzer 47, LED 47a, speaker, etc., can be considered examples of "notification units" that notify the cleaning instruction information.

By disseminating cleaning instruction information in this way, it becomes easier to perform cleaning tasks at the appropriate time, and it also helps prevent tasks from being forgotten.

Furthermore, the cleaning instruction information described above is not limited to being notified in accordance with the work schedule information pre-stored in the memory unit 42; it may also be notified in accordance with instructions received from the host terminal 1 via the communication unit 46. This allows the host terminal 1 to easily adjust the timing of notifying the cleaning instruction information. The cleaning instruction information may, for example, be received from the host terminal 1 via the mounting base 100 when the device is placed on the mounting base 100, or it may be received directly from the host terminal 1 at a predetermined timing using wireless communication or the like.

Furthermore, by acquiring worker information that identifies the worker who performed the cleaning work, this acquired worker information may be stored in the storage unit 42 along with information related to the cleaning work. This allows for easy management of work history and other data based on the information stored in the storage unit 42, and also allows for easy adjustment of the timing of the notification of the cleaning instruction information to match the actual work situation. Note that worker information can be acquired, for example, by reading the information code containing the worker information using the reading process described above. In this configuration, the control unit 41 and imaging unit 43, which function as "reading units," can correspond to an example of an "acquisition unit" that acquires worker information.

Furthermore, a cleaning work detection unit capable of detecting when cleaning work has been performed on the optical information reading device 10 may be provided, and the detection result of this cleaning work detection unit may be stored in the storage unit 42. As the cleaning work detection unit, for example, a sensor (for example, a sensor with the same function as the piezoelectric sensor used in the detection unit 45) can be used, located in a place where pressure is applied when the housing 11 is wiped during cleaning. Alternatively, for example, a temperature sensor capable of detecting the temperature drop when the housing 11 is wiped with alcohol may be used as the cleaning work detection unit, or an alcohol sensor may be used as the cleaning work detection unit. This allows for a more reliable record of the work history and enables adjustment of the timing of the notification of the cleaning instruction information according to the actual situation.

Furthermore, as described above, at least a portion of the work history and other data stored in the memory unit 42 may be transmitted to the host terminal 1 via the communication unit 46. The host terminal 1 may then notify the cleaning instruction information in response to instructions received from the host terminal 1 via the communication unit 46. This allows the host terminal 1 to easily grasp the work history related to the optical information reading device 10 being managed, and to appropriately adjust the timing of notifying the cleaning instruction information according to the actual work situation.

Furthermore, the characteristic features of this embodiment, such as the notification of cleaning instruction information to encourage cleaning work, can be applied to other embodiments as well.

[Eighth Embodiment]
Next, an optical information reading device according to the eighth embodiment of the present invention will be described with reference to the drawings.
This eighth embodiment differs from the first embodiment in that it is configured to determine whether a patient whose body temperature has been measured is experiencing a fever. Therefore, components that are substantially the same as those in the first embodiment are denoted by the same reference numerals, and their descriptions are omitted.

As shown in Figure 17, the optical information reading device 10c according to this embodiment is configured to include a temperature measurement unit 48 capable of measuring a patient's body temperature. The temperature measurement unit 48 is an infrared radiation thermometer, positioned within the housing 11, and configured to measure the body temperature of the patient's body part towards which the reading opening 21 is directed.

In this embodiment, patient information identifying a patient and their average body temperature information are linked and stored in a database in the storage unit 42. An information code Ca, which encodes the patient information, is displayed on the patient's wristband WB. Therefore, as illustrated in Figure 18, by starting the reading process with the reader 21 pointed towards the patient's wristband WB, the patient information is read from the information code Ca, and the body temperature measurement unit 48 measures the patient's body temperature near their wrist.

Furthermore, in the fever determination process performed by the control unit 41, the average body temperature information associated with the patient information read from the information code Ca is compared with the measurement result of the body temperature measurement unit 48 to determine whether or not the patient has a fever. Note that the reading of the information code Ca and the measurement of body temperature by the body temperature measurement unit 48 may be performed with a single pressing operation on the operating surface 34, or the patient information may be read from the information code Ca captured by the first pressing operation, and then the body temperature measurement by the body temperature measurement unit 48 may be performed with a second pressing operation. Also, the control unit 41 that performs the fever determination process may correspond to an example of a "determination unit" that determines whether or not the patient has a fever.

This allows for easy measurement of a patient's body temperature using the optical information reading device 10c, which facilitates wipe-and-disinfection. Furthermore, it makes it easy to determine whether the patient has a fever, thereby reducing the burden on nursing care.

Furthermore, patient information and the patient's average body temperature information may be stored in a database on the host terminal 1. In this case, by transmitting the read patient information and the measurement results from the body temperature measurement unit 48 to the host terminal 1, the host terminal 1 can determine whether the patient has a fever and receive the determination result from the host terminal 1.

Furthermore, patient information may include medical record information that should be used for medication decisions regarding that patient, and information to assist in medication decisions may be provided by utilizing this medical record information and the measurement results from the temperature measurement unit 48.

Furthermore, the characteristic configuration of this embodiment, which determines whether a patient whose body temperature has been measured is experiencing a fever, can also be applied to other embodiments.

[Ninth Embodiment]
Next, an optical information reading device according to the ninth embodiment of the present invention will be described with reference to the drawings.
This ninth embodiment differs from the first embodiment in that the coil for wireless power transmission is bonded to the inner surface on the reading side within an extension that extends in a thin plate shape. Therefore, components that are substantially the same as those in the first embodiment are denoted by the same reference numerals, and their descriptions are omitted.

As shown in Figure 19, a coil member for wireless power transmission (hereinafter also simply referred to as coil 49) is arranged inside the extension 12, which extends in a substantially thin plate shape in the direction facing the reading opening 21 from between the lower edge of the reading opening 21 on the gripping side and the gripping part 31.

As described above, since the coil 49 is positioned within the extension portion 12 that extends in a thin plate shape, the heat generated in the coil 49 during power transmission is dissipated from the reading side surface (hereinafter also referred to as the anti-mounting side 12b) and the gripping side surface (hereinafter also referred to as the mounting side 12c) of the extension portion 12. As the extension length of the extension portion increases, the heat dissipation area provided by the anti-mounting side 12b and the mounting side 12c increases, thus improving the heat dissipation performance of the coil 49 according to the extension length of the extension portion 12. Furthermore, the heat generated in the coil 49 is less likely to be transmitted to various electronic components housed in different parts of the housing 11 from the extension portion 12.

In particular, in this embodiment, the coil 49 is bonded to the inner surface 12d of the housing portion constituting the extension 12, which is on the reading side, using a highly thermally conductive adhesive 55, but not to the inner surface of the housing portion constituting the extension 12, which is on the gripping side. When power is supplied by placing the mounting side 12c of the extension 12 on the charging surface of the mounting base 100, which functions as a charger, the mounting side 12c has poor heat dissipation due to its proximity to the charging surface, while the heat dissipation of the opposite side 12b of the extension 12 is not affected by the charging surface. Therefore, by bonding the coil 49 to the inner surface 12d on the reading side, the heat generated in the coil 49 during charging is more easily transferred to the opposite side 12b, which has better heat dissipation, thus further improving the heat dissipation effect of the thin plate-shaped extension 12.

Furthermore, the characteristic configuration of this embodiment, in which the coil 49 for wireless power transmission is arranged within the extension portion 12 that extends in a thin plate shape, can also be applied to other embodiments.

[Tenth Embodiment]
Next, an optical information reading device according to the tenth embodiment of the present invention will be described with reference to the drawings.
In this tenth embodiment, the main difference from the fourth embodiment is that a protrusion is provided at a position on the central inner side of the operating surface. Therefore, components that are substantially the same as those in the fourth embodiment are denoted by the same reference numerals, and their descriptions are omitted.

As shown in Figure 20(A), the gripping portion 31 of the housing 11 according to this embodiment is provided with a projection 36 that protrudes inward at a position on the inner surface side of the central portion 34b of the operating surface 34a. The detection unit 45 according to this embodiment is configured to detect the strain generated in the operating surface 34a according to the amount of inward deformation of the projection 36.

When the operating surface 34a is touched, the central portion 34b deforms the most. Therefore, the inward movement of the protrusion 36 located on the inner surface of this central portion 34b can be increased, thereby improving the detection accuracy of the detection unit 45, and thus the operability of the device.

Furthermore, the outer peripheral portion 34c, which acts as the pivot point for deformation when the operating surface 34a is touched, is thinner than the central portion 34b due to the protrusion 36. This makes the operating surface 34a more easily deformable, thus further improving the detection accuracy of the detection unit 45. On the other hand, the thickness of the central portion 34b of the housing 11 increases. Compared to the case where the entire operating surface 34a is a thin-walled portion due to the absence of the protrusion 36, the resin flow during resin molding near the operating surface 34a improves, suppressing molding defects.

As a modification of this embodiment, an elastic member 37, such as a rubber member, may be interposed between the protruding portion 36 and the detection portion 45, as illustrated in Figure 20(B). This allows the stress transmitted to the detection portion 45 to be adjusted according to the thickness and elastic force of the elastic member 37. For example, excessive pressing force can be absorbed by the elastic member 37, preventing damage to the detection portion 45.

Furthermore, the characteristic configuration of this embodiment, in which a protrusion 36 is provided at a position on the central inner side of the operating surface, can be applied to other embodiments as well. For example, it can be applied to an operating surface 34 in which the central portion does not protrude outward. Also, characteristic configurations such as a modified version of this embodiment, in which an elastic member 37 is interposed between the protrusion 36 and the detection portion 45, can also be applied to other embodiments as well.

[Embodiment No. 11]
Next, an optical information reading device according to the 11th embodiment of the present invention will be described with reference to the drawings.
This eleventh embodiment differs from the third embodiment in that a pair of magnets arranged with different polarities in the insertion and removal direction are used for mounting and fixing. Therefore, components that are substantially the same as those in the third embodiment are denoted by the same reference numerals, and their descriptions are omitted.

In the configuration described in the third embodiment above, where the optical information reading device 10b is placed on the mounting base 100a at a predetermined position (the position most suitable for charging, etc.) by utilizing the attractive force between the magnet 52 of the optical information reading device 10b and the magnet 102 of the mounting base 100a, it is necessary to appropriately adjust the attractive force. If the attractive force between magnet 52 and magnet 102 is too strong, the force required to remove the optical information reading device 10b from the mounting base 100a will increase. Conversely, if the attractive force is too weak, the holding force using the magnets will be weakened.

In particular, the attractive force in the direction perpendicular to the opposing direction (the left-right direction in the example of Figure 10) is about 20-30% weaker than the attractive force in the opposing direction (the up-down direction in the example of Figure 10). Therefore, if the attractive force is weakened to the point where it is easy to remove, there is a possibility that the optical information reading device 10b may shift from its predetermined position or detach from the mounting base 100a if an external force perpendicular to the opposing direction—in this embodiment, an external force along the mounting surface 101—acts.

Therefore, in the optical information reading device 10d and mounting base 100b according to this embodiment, as illustrated in Figures 21 and 22, a pair of magnets arranged with different polarities in a predetermined direction along the mounting surface 101 (hereinafter also referred to as the insertion/removal direction) are used to hold the optical information reading device 10d in the predetermined position relative to the mounting base 100b.

Specifically, in the optical information reading device 10d, four magnets 52a to 52d of the same size are provided at the four corners of the rectangular area on the inner surface below the extension portion 12 that faces the mounting surface 101. The magnets 52a and 52b on the gripping portion side are arranged so that the mounting surface 101 side is the south pole, and the magnets 52c and 52d on the opposite gripping portion side are arranged so that the mounting surface 101 side is the north pole. Magnets 52a and 52c are positioned as a pair of magnets with different polarities, separated by a predetermined distance in the insertion/removal direction (for example, a distance of about 1 times the insertion/removal length of magnet 52a). Similarly, magnets 52b and 52d are positioned as a pair of magnets with different polarities, separated by the same predetermined distance in the insertion/removal direction. The predetermined interval may be set to a distance of approximately 0.5 to 2 times the insertion/removal length of magnet 52a, depending on the magnetic force and shape of each magnet 52a to 52d. Furthermore, in Figure 22 and Figure 24 (described later), for the sake of explanation, the "S" pole (facing the mounting surface 101) is indicated for magnets 52a and 52b, and the "N" pole (facing the mounting surface 101) is indicated for magnets 52c and 52d.

Furthermore, on the mounting base 100b, with respect to the optical information reading device 10d placed in the predetermined position, a magnet 102a is positioned on the inner surface of the mounting surface 101, facing magnet 52a, with the magnet 52a side being the north pole; a magnet 102b is positioned facing magnet 52b, with the magnet 52b side being the north pole; a magnet 102c is positioned facing magnet 52c, with the magnet 52c side being the south pole; and a magnet 102d is positioned facing magnet 52d, with the magnet 52d side being the south pole.

As a result, even when an external force (a rightward external force in Figure 23) acts on the optical information reading device 10d to pull it out along the insertion/removal direction, the attractive forces of magnets 52a and 102a, the attractive forces of magnets 52c and 102c, and the repulsive forces of magnets 52c and 102a act to counteract the external force, as illustrated in Figure 23. At the same time, the attractive forces of magnets 52b and 102b, the attractive forces of magnets 52d and 102d, and the repulsive forces of magnets 52d and 102b act to counteract the external force. Furthermore, in Figure 23, for the sake of explanation, the "S" pole (facing the mounting surface 101) is indicated for magnet 52a, the "N" pole (facing the mounting surface 101) is indicated for magnet 52c, the "N" pole (facing magnet 52a) is indicated for magnet 102a, and the "S" pole (facing magnet 52c) is indicated for magnet 102c.

Furthermore, even if an external force (a leftward external force in Figure 23) is applied to the optical information reading device 10d in the insertion/removal direction, the attractive forces of magnets 52a and 102a, the attractive forces of magnets 52c and 102c, and the repulsive forces of magnets 52a and 102c will act to counteract the external force. Simultaneously, the attractive forces of magnets 52b and 102b, the attractive forces of magnets 52d and 102d, and the repulsive forces of magnets 52b and 102d will act to counteract the external force.

In this way, by using a pair of magnets arranged so that their polarities differ in the insertion and removal directions for attraction between the optical information reading device 10d and the mounting base 100b, the attractive and repulsive forces generated as described above can be used as a holding force to counteract the external forces. Therefore, a strong holding structure resistant to external forces in the insertion and removal directions can be achieved without excessively increasing the magnetic attraction force.

Furthermore, as a modified example of this embodiment, as illustrated in Figure 24, even in an arrangement where magnets 52b and 52d are swapped with magnets 102b and 102d compared to Figure 22, the pair of magnets arranged so that their polarities differ in the insertion/removal direction can be used for attraction between the optical information reading device 10d and the mounting base 100b, thus achieving the above-mentioned effect.

Furthermore, the characteristic configuration of this embodiment, which utilizes a pair of magnets arranged so that their polarities differ in the insertion and removal directions for mounting and fixing, can also be applied to other embodiments.
