Description

The present invention relates to an optical information reader that reads symbols such as barcodes and two-dimensional codes.

It receives light from symbols such as barcodes and QR codes to be read, acquires image data of the symbol with an image sensor, and reads the information according to the symbol by analyzing the image data, such as a handy type. A hand-held optical information reader called is known (for example, Patent Document 1). Such an optical information reader is configured to arrange keys at the bottom of the touch panel. Further, in order to facilitate key operation, the portion where the key is arranged is formed to be narrower than the display portion so as to be suitable for gripping.

However, in this configuration, since the user grips the narrow grip portion with a finger other than the thumb of the handle, it is easy to operate the keys with the thumb, but as a result, the distance between the grip portion and the touch panel becomes long. There was a problem that it was difficult to operate the touch panel with the thumb of the hand.

On the other hand, in order to operate the touch panel, it is necessary to operate the touch panel with the thumb while grasping the back surface of the touch panel above the grip portion, but in this state, the optical information reading device cannot be sufficiently held, which is not possible. It is stable and there is a risk of dropping the optical information reader. Further, if the user's hand is small, the back surface of the touch panel cannot be sufficiently grasped, and the touch panel is placed on the palm, further increasing the sense of instability.

Furthermore, in this state, since the back part of the touch panel above the grip portion is gripped, the distance to the keys arranged at the bottom of the touch panel becomes long, and even if the keys are operated from this state, It becomes difficult for the thumb of the handle to reach. As a result, in some cases, the grip portion must be picked up again for operation, which may take time and effort, or the optical information reading device may be inadvertently dropped when the gripping portion is picked up again.

In this way, in an optical information reader equipped with a key and a touch panel, if the ease of key operation is enhanced, the touch panel operation becomes difficult, and conversely, if the touch panel operation is emphasized, the key operation becomes difficult and the key operation becomes difficult. There was a problem that it was difficult to achieve both operation and touch panel operation.

(Optical information reader 100)

The optical information reading device 100 shown in FIG. 1 is for a user to grasp a bar code or the like with one hand and operate a touch panel or keys. Here, the outline of the optical information reading device 100 will be described, and the description of each member will be described later.

The optical information reading device 100 is provided on a substantially plate-shaped housing 10 having a first main surface 11 and a second main surface 12 facing the first main surface, and the first main surface 11 for information. It includes a touch panel 20 that displays and accepts operation input by the user, and a key arrangement unit 30 in which a plurality of operation keys 31 provided below the touch panel 20 are arranged.

Further, as shown in FIG. 2A, on the second main surface 12 side, a battery accommodating portion 40 provided in a portion corresponding to the key arrangement portion 30, a ring portion 50 provided above the battery accommodating portion 40, and reading. It is provided with an image pickup unit 60 for imaging a target symbol. The housing 10 is provided above the ring portion 50, and forms a protruding portion 61 protruding from the first main surface 11 on the second main surface 12 side. An image pickup unit 60 is provided on the protrusion 61.

The ring portion 50 forms an opening 51 into which a user can insert a finger in the second direction d2 which intersects the first direction d1 which is the alignment direction of the touch panel 20 and the key arrangement portion 30. With such a configuration, when the optical information reading device 100 is used, the user can grip the lower part of the housing 10 including the key arrangement portion 30 and the battery accommodating portion 40 as a grip portion. Then, as shown in FIG. 3, the finger of one hand, for example, the middle finger can be hung on the ring portion 50, and the operation keys and the touch panel can be operated with the thumb of the same hand while stably holding the optical information reading device 100. ..

On the other hand, when the operation of the optical information reading device 100 is completed and the optical information reading device 100 is temporarily placed on a shelf or the like, the first main surface 11 of the housing 10 provided with the touch panel or the like of the optical information reading device 100 is turned to the front side. In other words, it is often mounted with the second main surface side of the housing facing the mounting surface CS. At this time, as shown in FIG. 4, the outer shape of the ring portion 50 brings the ring portion 50 and the protruding portion 61 into contact with the mounting surface CS, and the user inserts one finger into the opening 51 of the ring portion 50. In, a space S1 in which a user can insert another finger of the same hand is formed between the mounting surface CS and the battery accommodating portion 40.

When the space S1 is formed on the back surface of the battery accommodating portion 40 in this way, when the user tries to grip the optical information reading device 100, the grip portion can be easily gripped by the space S1. On the other hand, the conventional plate-shaped barcode reader does not have a ring portion on the back surface portion like the optical information reader of the present embodiment, so once it is mounted, it becomes a mounting surface. In many cases, the back surface of the barcode reader is in general contact with the grip portion, and the grip portion cannot be gripped directly. In this case, when the user grips the barcode reader, it is necessary to lift it with one hand and then grip it with the other hand, or lift it with one hand and then turn the barcode reader and re-grasp it. Is not easy to use. On the other hand, according to the optical information reading device 100 according to the first embodiment, by forming the space S1 on the back surface side of the grip portion, when the mounted optical information reading device 100 is picked up, the space S1 is used. One operation of inserting a finger and directly gripping the grip portion is sufficient, and an easy-to-use environment that does not require an operation such as re-grasping is realized.

Further, in the example of FIG. 4, in the posture in which the optical information reading device 100 is mounted, a space S3 is formed between the ring portion 50 and the protruding portion 61 and also between the mounting surface CS. As a result, the user can insert an index finger or the like into the space S3 when picking up the optical information reading device 100, and can further easily grip the optical information reading device 100.
[Modification 1]

However, the present invention does not limit the installation portion when the optical information reading device 100 is mounted on the mounting surface CS to the above configuration. For example, as shown in FIG. 5 as the optical information reading device 100'according to the first modification, the above-mentioned mounting surface is in a posture in which the ring portion 50 and the lower end portion of the battery housing portion 40 are in contact with the mounting surface CS. A space S2 into which a user can insert a finger may be formed between the battery storage unit and the battery storage unit. Also with this configuration, when the user picks up the optical information reading device 100, the user can similarly insert a finger, for example, a ring finger and a little finger into the space S2 to grip the grip portion. Further, similarly, a space S4 may be formed between the ring portion 50 and the projecting portion 61 and between the mounting surface CS. In this case, since the space S4 can be secured wider than the space S3 described above, there is an advantage that the index finger or the like can be easily inserted into the space S4. On the other hand, since the space S2 is relatively narrower than the space S1, FIG. 4 is preferable when considering the ease of inserting the ring finger or little finger.
(Case 10)

As shown in FIG. 1, the housing 10 according to the optical information reader 100 of the first embodiment has a substantially plate shape having a first main surface 11 and a second main surface 12. Here, the "plate shape" in the present specification includes not only a flat shape of the first main surface 11 and the second main surface 12, but also a shape in which concave portions and convex portions are formed on each main surface. I'm out.

A touch panel 20 for displaying information and receiving operation input by the user is provided on the first main surface 11 side. For the touch panel 20, for example, a display such as a liquid crystal display or an organic EL can be used. Below the touch panel 20, a key arrangement unit 30 in which a plurality of operation keys 31 are arranged is provided. By operating the operation keys 31, the user performs various operations on the display contents on the touch panel 20, and performs various processes such as irradiation and reading of illumination light and aiming light, and image capture.

The shape of the housing 10 is such that the touch panel portion is substantially rectangular when the optical information reading device 100 of FIG. 1 is viewed from the front. Further, the portion of the key arrangement portion 30 is substantially rectangular in width narrower than that of the touch panel 20. If the key arrangement portion 30 is narrower than the touch panel 20 and is used as a grip portion for gripping this portion, it is convenient to carry. However, the housing of the present embodiment is not limited to such a shape. For example, the touch panel 20 and the key arrangement unit 30 may have substantially the same width. Further, the corners of the rectangular shape may be chamfered or a curved portion may be included in a part thereof.
(Battery storage unit 40)

As shown in FIG. 2A, a battery accommodating portion 40 is provided on the second main surface 12 side of the housing 10. Specifically, the battery accommodating portion 40 is provided below the optical information reading device 100 of FIG. 2A, which is a portion corresponding to the key arrangement unit 30 on the second main surface 12. The battery storage unit 40 can have any shape that can store the battery. For example, in the present embodiment, it is formed along the longitudinal direction of the housing 10. Further, the battery accommodating portion 40 forms a partially convex curved surface near the center of the second main surface 12. Since the battery storage unit 40 is provided in a portion corresponding to the key arrangement unit 30, when the user carries the optical information reading device 100 or the like, the optical information reading unit including the battery storage unit 40 and the key arrangement unit 30 is read. In many cases, the lower part of the device 100 is gripped. Therefore, when the battery accommodating portion 40 forms a convex curved surface, when the user grips it, it fits the shape of the hand and can be easily gripped. However, the battery accommodating portion of the present embodiment is not limited to the above shape. For example, it may be a flat surface instead of a convex curved surface.

Further, as shown in FIG. 2A, a protrusion 41 may be provided at the lower end portion of the battery housing portion 40. The protrusion 41 projects in a direction away from the first main surface 11. By providing such a protrusion 41, when the optical information reading device 100 is mounted with the first main surface 11 facing up, the protrusion 41 comes into contact with the mounting surface, and the ring portion 50 and the protrusion 41, which will be described later, provide the protrusion 41. The lower end side of the space S2 in FIG. 5 can be formed slightly wider. As a result, it is possible to easily insert the user's finger into the space S2. However, the battery accommodating portion of the first embodiment is not limited to the embodiment in which the protrusion is formed at the lower end portion, and the protrusion may not be formed. In this case, the configuration of the battery housing can be further simplified.
(Notification unit 80)

A notification unit 80 may be formed above the battery storage unit 40 in FIG. 2A. The notification unit 80 is for notifying whether or not the symbol SB has been successfully read. The notification unit 80 can be formed at any position, but in the optical information reading device 100 according to the first embodiment, it is formed on a flat surface which is a substantially central portion of the second main surface 12. Further, the notification unit 80 is provided with a speaker and is configured to notify the user with a sound such as a buzzer sound or a voice. As a result, the user can aurally confirm whether or not the symbol SB has been successfully read, and it is possible to reduce oversights such as the intention of reading the symbol SB but not reading it. Further, the notification unit 80 may include a vibrator. This makes it possible to notify the user even of vibration.
(Ring part 50)

A ring portion 50 is further provided above the battery accommodating portion 40 in FIG. 2A. The ring portion 50 is a member for the user to hang the finger of one hand and operate the operation key 31 and the touch panel 20 with the thumb of the same hand while stably holding the optical information reading device 100. The ring portion 50 forms an opening 51 into which a user can insert a finger in the second direction d2 which intersects the first direction d1 which is the alignment direction of the touch panel 20 and the key arrangement portion 30. Further, the ring portion 50 does not need to form a completely closed loop, and may have a C-shape in which a gap is partially opened so that a finger cannot be pulled out.

The opening 51 may have an inner diameter that allows an average adult finger to be inserted, and can be designed to have an arbitrary size according to the target user. In the optical information reader 100 according to the first embodiment, the radius is set to about 1 cm as an example. Further, although the shape of the opening 51 is generally circular, it can also be elliptical or polygonal.

The ring portion 50 can be formed at an arbitrary position above the battery housing portion 40. The ring portion 50 of the present embodiment is formed at the position of the center of gravity of the housing 10. By forming the housing 10 at the position of the center of gravity, the housing 10 can be supported in a well-balanced manner when the housing 10 is gripped via the ring portion 50, and the load during use by the user can be reduced. .. Here, the "center of gravity position" in the present specification includes not only the position of the center of gravity in a strict sense but also the concept of the position of the center of gravity or the vicinity of the position of the center of gravity.
(Attachment 52)

As described above, the ring portion 50 can be in any form as long as the user can put his finger on it and operate it while stably holding the optical information reading device 100. In the first embodiment, a part of the ring portion 50 is configured by the attachment 52. As shown in FIG. 6, the attachment 52 is removable from the housing 10. By making the attachment 52 removable, the user can select whether or not to attach the ring portion according to the usage mode and preference, and a convenient environment is realized.
(Attachment body 53)

The attachment 52 includes an attachment main body 53 and a handle 54. The attachment main body 53 has a substantially rectangular shape extended in the second direction d2 with the attachment 52 attached to the housing 10. Further, a pair of engaging portions 55 and 55, which will be described later, are formed at both ends of the attachment main body portion 53, respectively.

As shown in FIGS. 6 and 7, the attachment main body 53 is bent so that both ends are horizontal planes and the intermediate portion sandwiched between the both ends is shaped along the shape of the second main surface 12. You may let me. In the example of the figure, the intermediate portion is curved so as to be slightly raised toward the center so as to follow the shape of the second main surface 12. With such a shape, the attachment 52 can be brought into contact with the second main surface 12 in a planar manner and can be stably attached to the housing 10. However, the shape of the attachment main surface 53 is not limited to the shape along the second main surface 12, and for example, a corner portion or a gap is formed between the second main surface 12 and the attachment main surface 53. It may be a thing. In particular, with the attachment 52 mounted on the housing 10, the attachment body 53 overlaps the notification unit 80 so as to form a gap between the notification unit 80 on the second main surface 12 and the attachment body 53. A dent may be formed in the portion. By doing so, it is possible to avoid a situation in which the speaker portion of the notification unit 80 that emits a buzzer sound or the like is blocked by the attachment 52, and it is possible to reduce the possibility that the buzzer sound or the like transmitted from the notification unit 80 becomes difficult to hear.

When the attachment main body 53 is attached to the housing 10, the attachment opening 56 may be opened at a position corresponding to the notification unit 80. By forming the attachment opening 56, it is possible to further avoid the situation where the attachment main body 53 blocks the speaker of the notification unit 80.

The attachment opening 56 can have an arbitrary shape that exposes the notification unit 80 to some extent. In the first embodiment, the attachment opening 56 has a substantially rectangular shape, but may be, for example, an elliptical shape or a polygonal shape.
(Handle part 54)

The handle portion 54 extends from the substantially central portion of the attachment main body portion 53 in the first direction d1 toward the battery storage portion 40. The handle portion 54 has a substantially arc shape. By forming the arc shape, when the user puts his / her finger on the handle portion 54, the shape follows the user's finger, so that the housing 10 can be held without discomfort. However, the handle portion of the present embodiment is not limited to the arc shape. For example, ones that form corners, ones that are generally linear, and the like can also be used.
(Mounting groove 13)

The attachment attachment portion is a member for attaching the attachment 52 to the housing 10. The attachment attachment portion can be in any form as long as the attachment 52 is attached to the housing. For example, the attachment portion 55 may be sandwiched between the attachment attachment portions, or the attachment attachment portion may be used as a screw or the like to screw the attachment 52 to the housing 10.

In the first embodiment, as the attachment mounting portion, a pair of mounting grooves 13 and 13 are formed on the second main surface 12 as shown in FIG. The pair of mounting grooves 13 and 13 have a shape extending in the first direction d1. Further, the pair of mounting grooves 13 and 13 are both ends of the second main surface 12 along the second direction d2, and are formed between the battery accommodating portion 40 and the image pickup portion 60.

FIG. 8 is a cross-sectional view of the optical information reader 100 showing one aspect of the mounting groove 13 and the attachment 52. As shown in this figure, the pair of mounting grooves 13 and 13 are formed by slightly recessing the second main surface 12 of the housing 10 so as to approach each other in the second direction d2 from both ends of the housing 10. There is. By inserting the pair of engaging portions 55 and 55, which will be described later, into the recessed portions, the attachment 52 can be easily attached to and detached from the housing 10.
(Engagement portion 55)

The pair of engaging portions 55 and 55 shown in FIG. 7 are provided at both ends of the attachment main body portion 53, respectively. The pair of engaging portions 55, 55 may have an arbitrary shape, for example, a rectangular shape, an arc shape, or the like, which can be inserted into the pair of mounting grooves 13 and 13 to mount the attachment 52 on the housing 10. The shape of the engaging portion 55 of the first embodiment is tapered toward the direction of being inserted into the mounting groove 13. Further, as shown in FIGS. 7 and 8, the tip portion 55a of the tapered engaging portion 55 is formed to be inserted into the mounting groove 13 and hooked. As a result, the engaging portion 55 and the groove portion 13 can be engaged with each other as shown in FIG.

As shown in FIG. 9, in the engaging portion 55 engaged with the mounting groove 13, the tip portion 55a functions like a hook. Therefore, even if the attachment 52 is pulled away from the housing 10, that is, in the direction d3 indicated by the arrow in FIG. 9, the attachment 52 can be prevented from coming off the housing 10.

Further, since the engaging portion 55 is tapered and the tip portion 55a is inserted into the mounting groove 13, as shown in FIG. 10, the contact portion of the engaging portion 55 with respect to the mounting groove 13 is generally the tip portion 55a. Is. In this state, when the attachment 52 is rotated in the rotation direction d4 indicated by the arrow, one of the tip portions 55a can be easily removed from the mounting groove 13 as shown in FIG.

Specifically, since the pair of engaging portions 55, 55 have a tapered shape and do not form corners or the like, when the attachment 52 is moved in the rotation direction d4, the pair of engaging portions 55, 55 Are unlikely to come into contact with the mounting groove 13 and get caught, and cannot be easily removed from the mounting groove 13. That is, only by rotating the attachment 52 in the rotation direction d4, one of the engaging portions 55 can be smoothly removed from the mounting groove 13. As a result, the attachment 52 can be easily removed from the housing 10.

In this way, since the attachment 52 is hard to be detached from the housing 10 in the direction d3 away from the housing 10, even if the user inadvertently pulls the attachment 52 when using the optical information reading device 100, the attachment 52 Can be reduced from the possibility that the optics will come off the housing 10.

On the other hand, since the attachment 52 is easily disengaged when rotated in the rotation direction d4, the user accidentally pinches his hand or touches his hand in an unnatural posture when using the optical information reading device 100. Even in such a case, the attachment 52 can be quickly removed from the housing 10. As a result, the optical information reading device 100 can be easily removed from the user's hand, and it is possible to avoid a situation in which the user's hand is burdened and injured in an unreasonable posture.
(Groove 14)

As described above, when the attachment 52 is attached to the mounting groove 13, the opening 51 of the ring portion 50 is formed by the second main surface 12 and the handle portion 54 of the attachment 52. Here, as shown in FIG. 2A, a groove portion 14 extending along the second direction d2 may be formed above the battery housing portion 40. In this case, the inner surface of the groove portion 14 and the handle portion 54 can form an opening 51 of the ring portion 50. By providing the groove portion 14, when the user hangs a finger along the groove portion 14, the user's finger and the housing 10 are engaged with each other via the groove portion 14, and the case where the groove portion 14 is not provided is more stable. It is possible to support the housing 10.

Further, since the groove portion 14 forms a part of the opening 51, the handle portion 54 is recessed inward of the housing 10 as compared with the case where the opening 51 is formed only by the handle portion 54. The amount of protrusion can be reduced, and a more compact optical information reader 100 can be realized.

The groove portion 14 can be in any form as long as the user can operate the operation keys 31 and the touch panel 20 while holding the optical information reading device 100 with one hand. In the first embodiment, it is formed on the upper part of the key arrangement portion 30 on the second main surface 12. Further, it is preferable to form the second main surface 12 at a position corresponding to the vicinity of the connection region between the key arrangement portion 30 and the touch panel 20. As a result, the user can put his / her finger on the groove 14 and operate the touch panel arranged above the key arrangement 30 in a state where the thumb can easily reach the touch panel.

The position where the groove portion 14 is formed may be formed in the vicinity of the position of the center of gravity of the housing 10 in addition to the above-mentioned location. By forming it near the position of the center of gravity, when the user grips the housing 10 through the groove 14, the housing 10 can be supported in a well-balanced manner, and the load during use by the user can be reduced. .. In the optical information reading device 100 according to the first embodiment, the position of the center of gravity of the housing 10 is slightly above the groove portion 14. By moving the center of gravity of the housing 10 closer to the tip portion, when the optical information reading device 100 is mounted on the mounting surface, the head side becomes heavier and the housing 10 can be easily mounted in the posture as shown in FIG. Can be done. As a result, the space S1 is formed, and the user can easily pick up the optical information reading device 100 mounted on the space S1.

The shape of the inner surface of the groove portion 14 can be any shape as long as the user can put a finger on the groove portion 14. For example, in the first embodiment, it has an arc shape. By forming the inner surface of the groove portion 14 in an arc shape, that is, in a shape along the user's finger, the optical information reading device 100 can be used without discomfort when the user puts the finger on the groove portion 14. However, the shape of the inner surface of the groove portion 14 of the present embodiment is not limited to the arc shape, and may be, for example, a corner portion.

The handle portion 54 of the attachment 52 may be formed so as to match the shape of the inner surface of the groove portion 14. For example, when the inner surface of the groove portion 14 is arcuate, the handle portion 54 is also arcuate so that the ring portion 50 can be formed into one substantially annular shape. With such a shape, when the user puts his / her finger on the handle portion 54, the housing 10 can be easily held along the user's finger.

Here, in the optical information reading device 100 of the first embodiment, even when the attachment 52 is not attached (hereinafter, referred to as the first support mode), the user hooks the finger on the groove 14, and the housing 10 and the finger are grooved. It is possible to engage via 14 and stably support the housing 10 along, for example, in the second direction d2. In this case, it is possible to save the trouble of attaching the attachment 52. Further, since the attachment 52 is not attached, the optical information reading device 100 can be made more compact and convenient to carry.

On the other hand, when the attachment 52 is attached (hereinafter referred to as a second support form), the groove portion 14 and the handle portion 54 of the attachment 52 form a ring portion 50 that forms an opening 51 in the second direction d2. Since the user inserts a finger into the ring portion 50 formed by the groove portion 14 and the handle portion 54, the housing 10 is supported more stably than when the attachment 52 is not attached, for example, along the second direction d2. It is possible. Further, the possibility that the optical information reading device 100 may fall from the hand can be reduced as compared with the case where the attachment 52 is not attached. By making the attachment 52 removable, it is possible to easily switch between the first support form and the second support form. As a result, the user can select the support form according to the usage mode and preference, and a user-friendly environment is realized.
[Modification 2]

As described above, in the optical information reading device 100 according to the first embodiment, the groove portion 14 is formed on the second main surface side of the housing 10. However, the optical information reader according to the present disclosure is not limited to the mode in which the groove portion is provided. For example, the housing may not be provided with a groove. Such an example is shown in FIG. 2B as an optical information reader 100'' according to the second modification. As shown in this figure, the housing 10 ″ of the optical information reading device 100 ″ according to the modified example 2 does not have a groove on the second main surface side and is formed as a flat surface or a curved surface of the attachment 52 ″. The ring portion 50'' is formed only by the addition. In this case, the configuration of the housing 10'' can be further simplified.
(Image pickup unit 60)

The optical information reading device 100 of the first embodiment further includes an imaging unit 60 that captures a symbol SB such as a two-dimensional code to be read. As shown in FIG. 12, the imaging unit 60 determines the reading position of the imaging unit 62 for imaging the symbol SB, the lighting module 63 for illuminating the symbol SB, and the optical information reading device 100. It is provided with an aiming module 64 that irradiates the indicated light. The image pickup unit 60 is provided on a protrusion 61, which will be described later.
(Protruding portion 61)

The protruding portion 61 is provided above the ring portion 50 as shown in FIGS. 2A, 4 and the like. The protruding portion 61 projects toward the second main surface 12 of the housing 10 in a direction away from the first main surface 11. The protrusion 61 also forms an inclined surface 65 inclined in a direction away from the ring portion 50 from the second main surface 12. By providing such an inclined surface 65, the angle of the protruding portion 61 can be made to be inclined with respect to the tip surface of the housing 10. As a result, the reading surface of the image pickup unit 60 is tilted diagonally downward to facilitate reading in the posture of holding the optical information reading device 100.

The protrusion 61 is further provided with an optical window 66 on its tip surface. The image pickup unit 60 described above is provided so as to appear from the housing 10 to the outside through the optical window 66 inside the protrusion 61. As a result, the image pickup unit 60 can image the symbol SB diagonally forward and downward through the optical window 66 provided at the tip of the protrusion 61.

FIG. 13 is a schematic view showing a state in which the symbol SB is imaged by the image pickup unit 60 provided on such a protrusion 61. As shown in this figure, when the user images the symbol SB with the optical information reading device 100, the symbol SB to be read is often arranged below the position of the user's hand. Therefore, by projecting the protruding portion 61 forward and diagonally downward with respect to the second main surface 12 via the inclined surface 65, it is possible to read the symbol SB in a natural posture.

As shown in FIG. 14, if the tip surface of the housing 10 is an optical window 66 without providing a protruding portion, it is necessary to greatly bend the wrist in order to direct the imaging unit 60 toward the symbol SB at the time of imaging, and the user needs to bend the wrist significantly. There is a risk of forcing an unreasonable posture. Therefore, by projecting the protruding portion 61 diagonally forward and downward as described above, it is possible to read the symbol SB in a reasonable posture.

Further, by providing the protruding portion 61, as shown in FIG. 4, when the user mounts the first main surface 11 of the housing 10 toward the front side, the ring portion 50 and the protruding portion 61 are mounted on the mounting surface CS. It is possible to form a space S1 in which a user can insert a finger between the mounting surface CS and the battery accommodating portion 40. This makes it easier for the user to put a finger in the space S1 formed on the back surface of the battery storage portion 40 and grip it, and a user-friendly environment is realized. In this way, by inclining the protruding portion 61 via the inclined surface 65, the image pickup unit 60 is inclined to an angle suitable for reading, and a space S1 is formed between the projection portion 61 and the mounting surface CS to form a grip portion. There is an advantage that the configuration can be easily gripped.

Further, when the ring portion 50 and the protruding portion 61 are mounted on the mounting surface CS as shown in FIG. 4, the position on the protruding portion 61 side including the touch panel 20 is lower than the lower end portion of the battery housing portion 40. In other words, the position of the lower end portion of the battery accommodating portion 40 is higher than that in the case where the lower end portion of the battery accommodating portion 40 is mounted on the ring portion 50 and the lower end portion of the battery accommodating portion 40 shown in FIG. As a result, the space S1 is made wider than the space S2, and it is possible to secure a sufficient space in which the user can insert a finger.

On the other hand, if the optical information reader 100 is placed as shown in FIG. 5, the touch panel 20 can be easily seen, but the space S2 becomes narrower, and it becomes more difficult to insert a finger as compared with the case of FIG. .. On the other hand, when the touch panel 20 is placed as shown in FIG. 4, the touch panel 20 becomes difficult to see, but the space S1 becomes wide, and a finger can be inserted to quickly and easily grip the lower end portion of the battery storage portion 40.

The user of the optical information reading device 100 usually does not operate the touch panel 20 once the optical information reading device 100 is mounted. On the other hand, in the work of reading a symbol or the like using the optical information reading device 100, agile operation is often required at the work site. Therefore, when the ease of gripping and the good handling of the optical information reading device 100 are emphasized, it is preferable to place the protruding portion 61 and the ring portion 50 in contact with the mounting surface CS.
(Charging terminal 70)

The optical information reading device 100 of the first embodiment may further include a charging terminal 70 for charging the optical information reading device 100. In the example of FIG. 1, the pair of positive and negative charging terminals 70 is provided above the touch panel 20 and substantially at the tip of the housing 10. Then, as shown in FIG. 15, the tip of the housing 10 including the charging terminal 70 is inserted into the charger 71 to charge the battery. In other words, the optical information reader 100 is set in the charger 71 with the grip portion facing the upper end with the top and bottom turned upside down from the time of use.

In conventional barcode readers and the like, a charging terminal is provided in the grip portion below the housing, and the grip portion is inserted into a charger to charge the battery. Therefore, even if an attempt is made to take out the barcode reader from the charger, it is often difficult to directly grip the grip portion because the grip portion is inserted into the charger. Therefore, first lift the tip including the display part protruding from the charger with one hand, then re-grasp it with the other hand, lift it with one hand, and then change the direction of the barcode reader with the same hand. It was necessary to change hands, such as having to re-hold it.

On the other hand, in the optical information reading device 100 according to the first embodiment, the charging terminal 70 is provided not on the grip portion side but on the touch panel 20 side. Then, the tip portion of the housing 10 including the touch panel 20 and the like is inserted into the charger 71 so that the grip portion including the key arrangement portion 30 and the like protrudes from the charger 71. Therefore, the user can easily grip the protruding grip portion. Further, at this time, by gripping the grip portion with the posture of the forward hand with the thumb side facing downward instead of the reverse hand, the user can use the optical information reading device 100 as it is without re-grasping the grip portion. In this way, the optical information reading device 100 can be smoothly taken out from the charger 71 in one operation, and the reading work can be started as it is, which improves usability.

Further, in a state where the optical information reading device 100 is set in the charger 71 in a posture opposite to that at the time of use, the display of the touch panel 20 is rotated by 180 ° in this posture so that the touch panel 20 can be easily visually recognized. You may do so. For example, the characters and figures of "charging" are displayed on the touch panel 20 by rotating them in a posture with the grip portion side facing up. As a result, even if the optical information reader 100 is set in the charger 71 in the opposite direction, the display will not be difficult to see.
