[0004] [Patent Document 1] U.S. Patent No. 7,195,169 Summary of the Invention [Problem to be solved by the invention]

[0005] In the optical information reader described in Patent Document 1, after a trigger is operated to capture an image, a key arrangement unit is operated to process the captured information. The trigger is operated while holding the handle with one hand, whereas the key arrangement unit is operated while supporting it with the other hand.

[0006] Therefore, with the optical information reader described in Patent Document 1, it is not easy to switch from operating the trigger to operating the key arrangement portion, as it requires both hands.

[0007] The present invention has been made in view of the above-mentioned problems, and has an object to provide an optical information reader that allows an operator to easily switch between operating the trigger and operating the key arrangement section. [Means for solving the problem]

[0008] According to one aspect of the present invention, an optical information reading device is a device that captures an image of a symbol to be read and reads information from the captured symbol. The optical information reading device includes an imaging unit, a reading unit, and a housing. The imaging unit captures an image in a predetermined direction. The reading unit reads information from the symbol from the image generated by the imaging unit. The imaging unit and the reading unit are disposed inside the housing. The housing has a first main surface and a second main surface opposite the first main surface. The first main surface has a display unit that displays information and a key arrangement unit located on the opposite side of the display unit in the predetermined direction. The optical information reading device further includes a grip unit, a trigger, and a finger insertion space. The grip unit is provided on the second main surface on the predetermined direction side of the key arrangement unit. The trigger is provided on the grip unit. When the trigger is pressed in a pressing direction, which is opposite the predetermined direction, the imaging unit starts capturing an image. The finger insertion space is formed between the housing and the grip unit. The finger insertion space extends in a direction along the display unit, intersecting the predetermined direction. [Effects of the Invention]

[0009] According to the optical information reader of the present invention, it is possible to easily switch between operating the trigger and operating the key arrangement portion. [Brief explanation of the drawings]

[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters, and description thereof will not be repeated.

[0012] In the following description, terms indicating positions or directions, such as "upper", "lower", "left", and "right", may be used. These terms are used for convenience to facilitate understanding of the embodiments, and unless otherwise clearly stated, do not relate to the directions in which the devices are actually implemented. <Embodiment 1>

[0013] Hereinafter, an optical information reader 100 according to a first embodiment of the present invention will be described with reference to the drawings. First, an outline of the optical information reader 100 according to the first embodiment will be described with reference to Fig. 1. Fig. 1 is a perspective view of the optical information reader 100 according to the first embodiment as viewed from above.

[0014] 1, the optical information reading device 100 is a device that captures an image of a symbol S to be read and reads information from the captured symbol S. The optical information reading device 100 includes an aimer light emitting unit 3, an imaging unit 4, a reading unit 5, a push button 6, a first switch 1, a second switch 2, and a control unit 7.

[0015] The aimer light emitting unit 3 emits aimer light L in a predetermined direction C. The imaging unit 4 captures an image in the predetermined direction C. The reading unit 5 reads information of the symbol S from the image generated by the imaging unit 4. The push button 6 can be pressed in a pressing direction P.

[0016] The first switch 1 is activated when the push button 6 is pressed a first amount in the pressing direction P. The second switch 2 is activated when the push button 6 is pressed a second amount that is greater than the first amount in the pressing direction P.

[0017] The control unit 7 controls the aimer light emitting unit 3 and the imaging unit 4. When the first switch 1 is actuated, the control unit 7 causes the aimer light emitting unit 3 to emit aimer light L. When the second switch 2 is actuated, the control unit 7 causes the imaging unit 4 to capture an image.

[0018] With the above-described configuration, when the push button 6 is pressed to a first pressing amount, the aimer light L is emitted. Then, when the push button 6 is pressed further to a second pressing amount, an image is taken. Therefore, the optical information reader 100 can intuitively perform the irradiation of the aimer light L and the subsequent image taking.

[0019] The aimer light L is a light for aiming, and may also be called an aimer, aiming, or aiming light.

[0020] The optical information reader 100 will be described in detail below with reference to FIG.

[0021] As shown in Fig. 1, the optical information reader 100 further includes a housing 8. The housing 8 has an aimer light emitting unit 3, an imaging unit 4, a first switch 1, and a second switch 2 disposed therein. The housing 8 has a light-transmitting unit 9. The light-transmitting unit 9 allows the aimer light L from the aimer light emitting unit 3 to pass from the inside of the housing 8 to the outside.

[0022] The first switch 1 and the second switch 2 are farther from the light-transmitting section 9 than the aimer light emitting section 3 and the imaging section 4. In other words, the aimer light emitting section 3 and the imaging section 4 are closer to the light-transmitting section 9 than the first switch 1 and the second switch 2.

[0023] Since the aimer light emitting unit 3 and the imaging unit 4 are closer to the light transmitting unit 9 than the first switch 1 and the second switch 2, the aimer light L from the aimer light emitting unit 3 and the imaging by the imaging unit 4 are not obstructed by the first switch 1 and the second switch 2. Therefore, the optical information reading device 100 can emit the aimer light L and then capture the image with high accuracy.

[0024] The reading unit 5 and the control unit 7 may also be arranged inside the housing 8. The reading unit 5 and the control unit 7 are also arranged at positions that do not interfere with the aimer light L from the aimer light emitting unit 3 and the imaging by the imaging unit 4.

[0025] The light-transmitting portion 9 is not particularly limited as long as it transmits light. The light-transmitting portion 9 is, for example, an opening formed in the housing 8.

[0026] The optical information reader 100 may include a handle 30 (also called a grip) provided on a housing 8, and a trigger 6 provided on the handle 30. The housing 8 may have a key arrangement section 12. The push button 6 is, for example, the trigger 6 or a key arranged on the key arrangement section 12.

[0027] Hereinafter, with reference to Figs. 1 and 2A to 2C, a mechanism for operating the first switch 1 and the second switch 2 by the force with which the push button 6 is pressed will be described.

[0028] Fig. 2A is a partial cutaway view of the push button 6 before it is pressed in by a first amount, Fig. 2B is a partial cutaway view of the push button 6 after it has been pressed in by the first amount, and Fig. 2C is a partial cutaway view of the push button 6 after it has been pressed in by a second amount.

[0029] 1, the optical information reader 100 further includes a force transmission member 40. The force transmission member 40 is a member that transmits the force exerted when the push button 6 is pressed to the first switch 1 and the second switch 2 as a force for operating the first switch 1 and the second switch 2. The force required to turn on the first switch 1 and the second switch 2 is called the operating force.

[0030] As shown in FIG. 2A, the force transmission member 40 includes, for example, a trigger rod 41, a linear cam 42, and a plunger 44.

[0031] The trigger rod 41 is connected to the push button 6 and can move together with the push button 6 in the pushing direction P and the opposite direction. The trigger rod 41 is biased in the direction opposite to the pushing direction P by a spring 49.

[0032] The linear cam 42 is connected to the trigger stick 41 and can move together with the push button 6 and the trigger stick 41 in the pushing direction P and the opposite direction. The linear cam 42 has a cam surface facing the first switch 1 and the second switch 2. The cam surface is inclined so that it approaches the first switch 1 and the second switch 2 on the side opposite to the pushing direction P.

[0033] The pusher 44 is restricted from moving in the pushing direction P and the opposite direction, and is arranged so as to be able to move freely toward the first switch 1 and the second switch 2 and in the opposite direction. The pusher 44 constitutes a follower of the linear cam 42. That is, the pusher 44 moves forward and backward relative to the first switch 1 and the second switch 2 by moving along the cam surface of the linear cam 42.

[0034] As shown in FIG. 2A, if the push button 6 is not pressed down to the first pressing amount, the pusher 44 will not protrude until the first switch 1 and the second switch 2 are actuated.

[0035] 2B, when the push button 6 is pressed down to the first pressing amount, the trigger stick 41 and the linear cam 42 also move to the first pressing amount in the pressing direction P. The movement of the linear cam 42 causes the pusher 44 to protrude along the cam surface toward the first switch 1 and the second switch 2. This protrusion causes the pusher 44 to activate the first switch 1.

[0036] 2C, when the push button 6 is pressed down to the second pressing amount, the trigger stick 41 and the linear cam 42 also move in the pressing direction P by the second pressing amount. The movement of the linear cam 42 causes the pusher 44 to protrude further along the cam surface toward the first switch 1 and the second switch 2. This protrusion causes the pusher 44 to activate the second switch 2. Note that when the first switch 1 and the second switch 2 are arranged adjacent to the push button 6, this is not limited to the example shown in FIGS. 2A to 2C, and the force transmission member 40 may be provided adjacent to the push button 6 on the side of the pressing direction P, or may be formed integrally with the push button 6.

[0037] The following describes in detail the first switch 1 and the second switch 2. First, with reference to Fig. 3A to Fig. 3C, a case where the first switch 1 and the second switch 2 are one tactile switch will be described.

[0038] Figure 3A is a cross-sectional view of the tactile switch when neither the first switch 1 nor the second switch 2 is actuated. Figure 3B is a cross-sectional view of the tactile switch when the first switch 1 is actuated. Figure 3C is a cross-sectional view of the tactile switch when the second switch 2 is actuated.

[0039] As shown in FIG. 3A, one tactile switch has a first metal dome 73, a first fixed contact 74, a second metal dome 75, a second fixed contact 76, and a third fixed contact 77.

[0040] The first metal dome 73 is electrically connected to the first fixed contact 74. The first metal dome 73 is not electrically connected to the second metal dome 75 when not pressed.

[0041] The second metal dome 75 is electrically connected to the second fixed contact 76. The second metal dome 75 is not electrically connected to the third fixed contact 77 when not pressed.

[0042] 3B, when the first metal dome 73 is pressed, it is electrically connected to the second metal dome 75. Therefore, the first metal dome 73, the first fixed contact 74, and the second metal dome 75 constitute the first switch 1.

[0043] 3C , when the first metal dome 73 is further pressed, it electrically connects the second metal dome 75 to the third fixed contact 77. Therefore, the second metal dome 75, the second fixed contact 76, and the third fixed contact 77 constitute the second switch 2.

[0044] The first switch 1 and the second switch 2 of the tactile switch shown in Figures 3A to 3C share a common actuation direction A. Similarly, the first switch 1 and the second switch 2 shown in Figures 4 to 8B described below share a common actuation direction A.

[0045] The common actuation direction A allows for proper transmission of the force applied to the push button 6 and the force that activates the first switch 1 and the second switch 2. Therefore, the optical information reader 100 can irradiate the aimer light L and then capture an image with high accuracy.

[0046] Next, preferred examples of the first switch 1 and the second switch 2 will be described with reference to Figures 4 and 5. Figure 4 is a cross-sectional view of the first switch 1 and the second switch 2 arranged in series. Figure 5 is an exploded perspective view (left) and a cross-sectional view (right) of the first switch 1 or the second switch 2.

[0047] 4, the first switch 1 and the second switch 2 are independent switches. Therefore, the durability of the first switch 1 and the second switch 2 is high. As a result, the optical information reader 100 has independent, highly durable switches, which can reduce the occurrence of breakdowns even when used frequently.

[0048] The switches of the optical information reader 100, which is a handheld terminal or the like, are pressed much more frequently than those of devices equipped with tactile switches (such as digital cameras). Therefore, the optical information reader 100 is required to have higher durability than digital cameras or the like. Therefore, the optical information reader 100 can meet the required high durability by being equipped with independent first and second switches 1 and 2 rather than tactile switches.

[0049] 4, the first switch 1 and the second switch 2 are arranged in series along an actuation direction A, which is the direction for actuation. Therefore, when either the first switch 1 or the second switch 2 is pressed in the actuation direction A, the first switch 1 or the second switch 2 is actuated according to the amount of pressing. As a result, the optical information reader 100 can be made smaller because the mechanism for actuating the first switch 1 and the second switch 2 is simplified.

[0050] The actuation force of the first switch 1 is smaller than the actuation force of the second switch 2. Therefore, when the first switch 1 and the second switch 2, which are arranged in series, are pressed by the pusher 44, the first switch 1 is actuated first, and then the second switch 2 is actuated.

[0051] The point in time when the first switch 1 is actuated, that is, when the force pressing the first switch 1 reaches the actuation force of the first switch 1, is the point in time when the push button 6 is pressed a first depression amount. The point in time when the second switch 2 is actuated, that is, when the force pressing the second switch 2 reaches the actuation force of the second switch 2, is the point in time when the push button 6 is pressed a second depression amount.

[0052] 4 and 5, the first switch 1 has a first circuit board 61 and a first movable part 71. The first circuit board 61 is electrically connected to operate the first switch 1. The first movable part 71 is moved in an operating direction A to electrically connect the first circuit board 61.

[0053] The second switch 2 has a second circuit board 62 and a second movable part 72. The second circuit board 62 operates the second switch 2 when it is electrically connected. The second movable part 72 operates the second circuit board 62 when it moves in an operating direction A. The first movable part 71 and the second movable part 72 face each other.

[0054] The above-described configuration allows for a simple arrangement of the first switch 1 and the second switch 2. Therefore, the optical information reader 100 can be made smaller due to the simple arrangement of the first switch 1 and the second switch 2.

[0055] As shown in FIG. 5, the first switch 1 and the second switch 2 each have mounting bases 51, 52, metal domes 61A, 62A, edge fixed contacts 61B, 62B, central fixed contacts 61C, 62C, a cover plate 54, push plates 71A, 72A, and a film 53. On the mounting bases 51 and 52, metal domes 61A and 62A, edge fixed contacts 61B and 62B, center fixed contacts 61C and 62C, a film 53, and a cover plate 54 are arranged.

[0056] The metal domes 61A and 62A are electrically connected to the edge fixed contacts 61B and 62B. When not pressed, the metal domes 61A and 62A are not electrically connected to the central fixed contacts 61C and 62C. When pressed, the metal domes 61A and 62A deform, and are therefore electrically connected to the central fixed contacts 61C and 62C.

[0057] The cover plate 54 holds the push plates 71A and 72A in the center. When pressed, the push plates 71A and 72A deform, thereby pressing the metal domes 61A and 62A via the film 53.

[0058] The metal dome 61A, edge fixed contact 61B, and center fixed contact 61C of the first switch 1 constitute a first circuit board 61. The first circuit board 61 is in a conductive state when the metal dome 61A is also electrically connected to the center fixed contact 61C in the first switch 1. The push plate 71A of the first switch 1 constitutes a first movable part 71.

[0059] The metal dome 62A, edge fixed contact 62B, and center fixed contact 62C of the second switch 2 constitute the second circuit board 62. The second circuit board 62 is in a conductive state when the metal dome 62A is also electrically connected to the center fixed contact 62C in the second switch 2. The push plate 72A of the second switch 2 constitutes the second movable part 72.

[0060] Next, another example of the first switch 1 and the second switch 2 arranged in series will be described with reference to Fig. 6 and Fig. 7. Fig. 6 is a cross-sectional view of another example of the first switch 1 and the second switch 2 arranged in series. Fig. 7 is a cross-sectional view of yet another example of the first switch 1 and the second switch 2 arranged in series.

[0061] As shown in Fig. 6, the mounting base 51 of the first switch 1 and the push plate 72A of the second switch 2 face each other. The push plate 71A of the first switch 1 can be pressed by the plunger 44. The first switch 1 and the second switch 2 shown in Fig. 6 may be arranged in a reversed manner. That is, although not shown, the push plate 71A of the first switch 1 and the mounting base 52 of the second switch 2 may face each other, and the push plate 72A of the second switch 2 may be arranged in a manner that can be pressed by the plunger 44.

[0062] As shown in Fig. 7, the mounting base 51 of the first switch 1 and the mounting base 52 of the second switch 2 face each other. The push plate 71A of the first switch 1 can be pressed by the plunger 44. The first switch 1 and the second switch 2 shown in Fig. 7 may be arranged in a reversed order. That is, although not shown, the push plate 72A of the second switch 2 may be arranged in a manner that can be pressed by the plunger 44.

[0063] 6 and 7, the first switch 1 and the second switch 2 are simply arranged, similar to the configuration shown in Fig. 4. Therefore, the optical information reader 100 can be made smaller due to the simply arranged first switch 1 and second switch 2.

[0064] The first switch 1 and the second switch 2 in the examples shown in Figures 4, 6, and 7 are all arranged in series. The first switch 1 and the second switch 2 in the example shown in Figure 4 do not require high precision for the mounting bases 51, 52 compared to the first switch 1 and the second switch 2 in the examples shown in Figures 6 and 7, making them easier to manufacture.

[0065] Next, a first switch 1 and a second switch 2 arranged in parallel will be described with reference to Figures 8A and 8B. Figure 8A is a cross-sectional view of the first switch 1 and the second switch 2 arranged in parallel. Figure 8B is a cross-sectional view of another example of the first switch 1 and the second switch 2 arranged in parallel.

[0066] 8A and 8B, the first switch 1 and the second switch 2 are arranged in parallel in a direction perpendicular to the actuation direction A. Therefore, the first switch 1 and the second switch 2 can be made thinner. As a result, the optical information reader 100 can be made smaller in size due to the first switch 1 and the second switch 2 that can be made thinner.

[0067] When the first switch 1 and the second switch 2 are arranged in parallel, the pusher 44 has a first pushing portion 45 that pushes the first switch 1 and a second pushing portion 46 that pushes the second switch 2. The pusher 44 is configured so that the first pushing portion 45 pushes the first movable portion 71 first, and the second pushing portion 46 pushes the second movable portion 72 later. In other words, the distance between the second pushing portion 46 and the second movable portion 72 is longer than the distance between the first pushing portion 45 and the first movable portion 71.

[0068] Specifically, as shown in FIG. 8A, the first switch 1 and the second switch 2 are arranged on a common surface, and the second pressing portion 46 is shorter than the first pressing portion 45. Alternatively, as shown in FIG. 8B, the surface on which the first switch 1 is arranged protrudes 59 toward the plunger 44 more than the surface on which the second switch 2 is arranged, and the first pressing portion 45 and the second pressing portion 46 have the same length. With the configurations shown in FIGS. 8A and 8B, for example, even if the first switch 1 and the second switch 2 are the same type of switch and the actuation forces of the first switch 1 and the second switch 2 are the same, the first switch 1 will actuate first, and the second switch 2 will actuate later. Note that by supporting the mounting base 51 of the first switch 1, which will actuate first, with an elastic member having a stronger resilience than the metal dome 61A, the possibility of the first switch 1 being damaged by additional force applied to the first switch 1 before the second switch 2 is actuated can be reduced.

[0069] 8A and 8B, any configuration may be used as long as the first switch 1 is actuated by a first depression amount and the second switch 2 is actuated by a second depression amount. For example, if the actuating force of the first switch 1 is smaller than the actuating force of the second switch 2, the first switch 1 will actuate first and the second switch 2 will actuate later, even if the first switch 1 and the second switch 2 are arranged on the same plane and the lengths of the first pressing portion 45 and the second pressing portion 46 of the plunger 44 are the same.

[0070] When the first switch 1 and the second switch 2 are arranged in parallel, the difference between the first and second depression amounts can be easily increased by making the distance between the second pressing portion 46 and the second movable portion 72 longer than the distance between the first pressing portion 45 and the first movable portion 71.

[0071] Hereinafter, with reference to FIG. 9 and FIGS. 10A to 10C, a mechanism for providing tactile feedback to the user that the push button 6 has been pressed by the first pressing amount will be described.

[0072] Fig. 9 is a partial cutaway view showing the tactile feedback mechanism 80. Fig. 10A is a cross-sectional view taken along line XX in Fig. 9, showing the state before the push button 6 is pressed down a first amount. Fig. 10B is a cross-sectional view taken along line XX in Fig. 9, showing the state after the push button 6 has been pressed down a first amount. Fig. 10C is a cross-sectional view taken along line XX in Fig. 9, showing the state after the push button 6 has been pressed down a second amount.

[0073] 9, the optical information reader 100 further includes a tactile feedback mechanism 80. The tactile feedback mechanism 80 is connected to the push button 6. The tactile feedback mechanism 80 may be indirectly connected to the push button 6 (via the trigger stick 41 or the like), or may be directly connected to the push button 6 (although not shown).

[0074] 10A to 10C, the tactile feedback mechanism 80 has a first member 81 and a second member 82. The first member 81 and the second member 82 can fit together. The first member 81 and the second member 82 fit together when the push button 6 is pressed a first pressing amount.

[0075] When the push button 6 is pressed by the first pressing amount, the first member 81 and the second member 82 fit together, and tactile feedback due to the fitting is transmitted to the push button 6. Therefore, the optical information reader 100 can use the tactile feedback mechanism 80 to provide tactile feedback to the user that the push button 6 has been pressed by the first pressing amount.

[0076] The tactile feedback mechanism 80 further includes a leaf spring holder 89. The leaf spring holder 89 is connected to the push button 6 either indirectly or directly.

[0077] The first member 81 is a pair of leaf springs. The first member 81, which is a pair of leaf springs, is held by a leaf spring holder 89. Therefore, when the push button 6 is pressed, the first member 81 moves together with the leaf spring holder 89 in the pressing direction P. The first member 81 has a double bent portion 81A in each of the pair of leaf springs. These double bent portions 81A are bent so as to approach each other.

[0078] The second member 82 is a block that guides the first member 81, which is a pair of leaf springs. The second member 82 has an expanded portion 83, a recessed portion 84, and a parallel portion 85. The expanded portion 83 is a portion whose width increases toward the pushing direction P side. The recessed portion 84 is connected to the portion of the expanded portion 83 where the width is greatest. The parallel portion 85 is connected from the recessed portion 84 to the pushing direction P side.

[0079] As shown in FIG. 10A, when the push button 6 is not pressed, or when the push button 6 is pressed but does not reach the first pressing amount, the double bent portion 81A is guided to the widened portion 83.

[0080] 10B, when the push button 6 is pressed down to the first pressing amount, the double bent portion 81A passes over the widened portion 83 and enters the recessed portion 84. When the double bent portion 81A enters the recessed portion 84, that is, when the first member 81 and the second member 82 are fitted together, an impact (tactile feedback) caused by the fitting is transmitted to the push button 6 via the leaf spring holder 89.

[0081] 10C , when the push button 6 is pressed further beyond the first pressing amount, the double bent portion 81A leaves the recessed portion 84 and is guided into the parallel portion 85. Although not shown, a separate recessed portion may be formed in the second member 82 into which the double bent portion 81A enters when the push button 6 is pressed in the pressing direction P by the second pressing amount. When the push button 6 is pressed in the pressing direction P by the second pressing amount, the double bent portion 81A enters the separate recessed portion, providing further tactile feedback to the push button 6.

[0082] Next, a tactile feedback mechanism 80 different from that shown in FIGS. 10A to 10C will be described with reference to FIGS. 11A to 11C.

[0083] Figure 11A is a cross-sectional view of another example of haptic feedback mechanism 80, showing a state corresponding to Figure 10A. Figure 11B is a cross-sectional view of another example of haptic feedback mechanism 80, showing a state corresponding to Figure 10B. Figure 11C is a cross-sectional view of another example of haptic feedback mechanism 80, showing a state corresponding to Figure 10C.

[0084] 11A, the first member 81 has outwardly bent portions 81B on each of a pair of leaf springs. These outwardly bent portions 81B are bent so that they move away from each other towards their tips.

[0085] The second member 82 has a small-width parallel portion 86 and an inclined portion 87. The small-width parallel portion 86 is located on the opposite side of the pushing direction P. The inclined portion 87 is connected to the small-width parallel portion 86 on the side of the pushing direction P. The surface of the inclined portion 87 is aligned with the surface of the outwardly bent portion 81B.

[0086] As shown in FIG. 11A, when the push button 6 is not pressed in, or when the push button 6 is pressed in but does not reach the first pressing amount, the outwardly bent portion 81B is guided by the narrow parallel portion 86.

[0087] 11B, when the push button 6 is pressed down to the first depression amount, the bent portion of the outwardly bent portion 81B reaches the boundary between the narrow-width parallel portion 86 and the inclined portion 87, so that the first member 81 and the second member 82 fit together. If the push button 6 is pressed down further, the bent portion of the outwardly bent portion 81B is guided by the inclined portion 87, and the force required to press the push button 6 increases. This increase in force (tactile feedback) is transmitted to the push button 6 via the leaf spring holder 89.

[0088] 11C, when the push button 6 is further pressed and exceeds the first pressing amount, the outwardly bent portion 81B leaves the boundary and is guided to the inclined portion 87. Therefore, the force required to press the push button 6 after exceeding the first pressing amount (FIG. 11C) is significantly greater than the force required to press the push button 6 up to the first pressing amount (FIG. 11A).

[0089] The case where the optical information reader 100 is an attachment type will be described below with reference to Fig. 12. Fig. 12 is an exploded perspective view of the attachment type optical information reader 100 as viewed from above.

[0090] The optical information reader 100 further includes a main body 98 and a detachable part 90. The detachable part 90 is detachable from the main body 98.

[0091] At least the first switch 1 and the second switch 2 are disposed in the main body 98. The main body 98 has a communication hole 99. The communication hole 99 communicates with the first switch 1 and the second switch 2 from the outside.

[0092] At least the push button 6 is disposed on the detachable part 90. The detachable part 90 has a protruding part 44 that protrudes when the push button 6 is pressed in the pressing direction P. The protruding part 44 is, for example, a pusher 44.

[0093] When the push button 6 is pushed in the pushing direction P by a first pushing amount with the detachable part 90 attached to the main body part 98, the protruding part 44 protrudes through the communicating hole 99 until the first switch 1 is activated. When the push button 6 is pushed in the pushing direction P by a second pushing amount with the detachable part 90 attached to the main body part 98, the protruding part 44 protrudes through the communicating hole 99 until the second switch 2 is activated.

[0094] The optical information reader 100 includes a main body 98 and a detachable part 90, allowing the user to select the main body 98 or detachable part 90 that is most suitable for use. Furthermore, the optical information reader 100 has the components that require waterproofing arranged in the main body 98, thereby improving waterproofing.

[0095] An optical information reader 100 without a grip part 30 will be described below with reference to Fig. 13. Fig. 13 is an exploded side view of the optical information reader 100 without a grip part 30.

[0096] 13, the housing 8 has a first main surface 10 and a second main surface 20 that is the surface opposite to the first main surface 10. The first main surface 10 and the second main surface 20 are not necessarily limited to flat surfaces, and may be curved surfaces or surfaces with irregularities.

[0097] The first main surface 10 has a display section 11 and a key arrangement section 12. The display section 11 displays information. The key arrangement section 12 is located on the opposite side of the display section 11 in the predetermined direction C.

[0098] A push button 6 is arranged on the second main surface 20. The push button 6 is a trigger 6 that is pressed in the opposite direction to the predetermined direction C. In the example shown in FIG. 13, the optical information reader 100 is an attachment type that includes a main body 98 and a detachable part 90. The side of the detachable part 90 that is attached to the main body 98 also constitutes the second main surface 20.

[0099] The push button 6 is the trigger 6, and since there is no grip portion 30, the area to be gripped is the periphery of the key arrangement portion 12. Therefore, the optical information reader 100 can eliminate the need to change grip from operating the trigger 6 to operating the key arrangement portion 12.

[0100] 13, the optical information reader 100 further includes a trigger guard 60 around the trigger 6. A finger is placed on the trigger guard 60 when operating the key arrangement section 12. Therefore, by including the trigger guard 60, the optical information reader 100 can improve operability and portability.

[0101] The optical information reader 100 shown in Fig. 13 does not have a grip part 30 and differs from the optical information reader 100 shown in Fig. 12 and up in the arrangement of the push button 6 which is the trigger 6. Other than the arrangement of the grip part 30 and the push button 6, the optical information reader 100 shown in Fig. 13 is the same as the optical information reader 100 shown in Fig. 12 and up.

[0102] The optical information reader 100 shown in FIG. 13 is not limited to an attachment type having a main body 98 and a detachable part 90, but may be an integrated type. <Embodiment 2>

[0103] An optical information reader 100 according to a second embodiment of the present invention will be described below with reference to the drawings. First, an outline of the optical information reader 100 according to the second embodiment will be described with reference to Fig. 14. Fig. 14 is a perspective view of the optical information reader 100 according to the second embodiment as viewed from above.

[0104] 14, the optical information reading device 100 is a device that captures an image of a symbol S to be read and reads information from the captured symbol S. The optical information reading device 100 includes an imaging unit 4, a reading unit 5, and a housing 8.

[0105] The imaging unit 4 captures an image in a predetermined direction C. The reading unit 5 reads information on the symbol S from the image generated by the imaging unit 4.

[0106] The housing 8 has the imaging unit 4 and the reading unit 5 disposed therein. The housing 8 has a first main surface 10 and a second main surface 20 opposite to the first main surface 10.

[0107] The first main surface 10 has a display section 11 and a key arrangement section 12. The display section 11 displays information. The key arrangement section 12 is located on the opposite side of the display section 11 in the predetermined direction C.

[0108] The optical information reader 100 further includes a grip portion 30, a trigger 6, and a finger insertion space 29.

[0109] The grip portion 30 is provided on the second main surface 20 on the side of the key arrangement portion 12 in the predetermined direction C. The trigger 6 is provided on the grip portion 30. The trigger 6 starts capturing images with the imaging unit 4 when pressed in a pressing direction P, which is the opposite direction to the predetermined direction C. A finger insertion space 29 is formed between the housing 8 and the grip portion 30. The finger insertion space 29 extends in a direction along the display unit 11, intersecting the predetermined direction C.

[0110] With the above-described configuration, when switching from operating the trigger 6 to operating the key arrangement portion 12, the finger is inserted into the finger insertion space 29. Therefore, the optical information reader 100 can easily switch from operating the trigger 6 to operating the key arrangement portion 12.

[0111] Next, with reference to FIGS. 15A to 15D, the changing of the optical information reader 100 will be specifically described.

[0112] 15A to 15D are all perspective views of the optical information reader 100 viewed from above. FIG. 15A shows a state in which the trigger 6 is being operated. FIG. 15B shows a first stage in which the user changes his / her grip from operating the trigger 6 to operating the key arrangement portion 12. FIG. 15C shows a second stage in which the user changes his / her grip from operating the trigger 6 to operating the key arrangement portion 12. FIG. 15D shows a state in which the key arrangement portion 12 is being operated.

[0113] 15A, when the trigger 6 is operated with the index finger, the grip portion 30 is gripped with the remaining four fingers and the palm. In this state, the trigger 6 can be operated.

[0114] 15B, in order to change grip, the index finger is inserted into finger insertion space 29. Then, as shown in FIG. 15C, with the index finger still in finger insertion space 29, the remaining four fingers and the palm are opened from grip portion 30.

[0115] 15D, the index finger remains in the finger insertion space 29, and the remaining four fingers and palm grasp the periphery of the key arrangement portion 12. In this state, the key arrangement portion 12 can be operated.

[0116] 15A to 15D, the gripping can be changed using only one hand, without the need for the other hand. The movement for changing the grip is completed by simply moving the index finger from the trigger 6 to the finger insertion space 29 (FIGS. 15A and 15B), opening the remaining four fingers and palm from the gripping portion 30 (FIG. 15C), and gripping the periphery of the key arrangement portion 12 with the remaining four fingers and palm (FIG. 15D).

[0117] The arrangement of the finger insertion space 29 will be described in detail below with reference to Fig. 16. Fig. 16 is a perspective view of the optical information reader 100 as seen from above.

[0118] 16, the second main surface 20 has a corresponding surface 21 that corresponds to the key arrangement portion 12. The finger insertion space 29 includes a point where a plane along the corresponding surface 21 and an axis 30A of the grip portion 30 intersect.

[0119] The above-described configuration brings the center of gravity of the housing 8 closer to the finger insertion space 29. Therefore, the optical information reader 100 can be made more stable when it is changed over.

[0120] The axis 30A of the grip portion 30 is the centroid of the cross section of the grip portion 30. The plane along the corresponding surface 21 and the axis 30A of the grip portion 30 do not necessarily have to be perpendicular to each other, but may intersect.

[0121] The finger insertion space 29 is located between the key arrangement portion 12 and the trigger 6 in the predetermined direction C. In other words, the finger insertion space 29 is located on a path along which a finger moves from the trigger 6 to the key arrangement portion 12 in the predetermined direction C.

[0122] The above-described configuration makes it possible to move a finger in stages from the trigger 6 through the finger insertion space 29 to the key arrangement section 12 in the predetermined direction C. Therefore, the risk of the optical information reader 100 being dropped when it is changed over can be reduced.

[0123] The finger insertion space 29 is located on the axis 30A of the grip part 30 between the key arrangement part 12 and the trigger 6. In other words, the finger insertion space 29 is located on the axis 30A of the grip part 30 on the path along which the finger moves from the trigger 6 to the key arrangement part 12.

[0124] The above-described configuration makes it possible to move a finger in stages on the axis 30A of the grip part 30 from the trigger 6 through the finger insertion space 29 to the key arrangement part 12. Therefore, the risk of the optical information reader 100 being dropped when it is changed over can be reduced.

[0125] Next, another example of the finger insertion space 29 will be described with reference to Fig. 17. Fig. 17 is a perspective view of the optical information reader 100 as seen from above.

[0126] 17, the optical information reader 100 is of an attachment type. That is, the optical information reader 100 further includes a main body 98 and a detachable part 90. The detachable part 90 is attachable to and detachable from the main body 98.

[0127] At least the housing 8 is disposed in the main body 98. At least the grip portion 30 and the trigger 6 are disposed in the detachable portion 90. The finger insertion space 29 is formed by attaching the detachable portion 90 to the main body 98.

[0128] The optical information reader 100 includes a main body 98 and a detachable part 90, allowing the user to select the main body 98 or detachable part 90 that is most suitable for use. Furthermore, the optical information reader 100 has the components that require waterproofing arranged in the main body 98, thereby improving waterproofing.

[0129] Although not shown, finger insertion space 29 may be formed in detachable part 90 rather than being formed by attaching detachable part 90 to main body part 98. By forming finger insertion space 29 in detachable part 90, even if a finger is placed in finger insertion space 29, no force is generated to separate main body part 98 and detachable part 90.

[0130] The detachable part 90 has a protrusion 44 that protrudes when the trigger 6 is pushed in the pushing direction P. The main body part 98 has a communication hole 99 through which the protrusion 44 can pass. When the trigger 6 is pushed in the pushing direction P with the detachable part 90 attached to the main body part 98, the protrusion 44 protrudes through the communication hole 99 until the imaging part 4 captures an image.

[0131] Even in the attachment-type optical information reader 100, the protrusion 44 and the communication hole 99 simplify the configuration for capturing an image using the trigger 6. Therefore, the optical information reader 100 can have a simple configuration.

[0132] The second main surface 20 has a battery storage section 23 at a position corresponding to the key arrangement section 12. The detachable section 90 has a cover section 93. The cover section 93 covers the battery storage section 23 when the detachable section 90 is attached to the main body section 98.

[0133] The cover part 93 of the detachable part 90 covers the battery storage part 23, eliminating the need for an additional battery cover to cover the battery storage part 23. Therefore, the optical information reader 100 can reduce the number of parts.

[0134] The cover part 93 preferably not only covers the battery storage part 23 but also fits into the battery storage part 23. The cover part 93 has a battery fitting part 92 for fitting into the battery storage part 23. By fitting the cover part 93 into the battery storage part 23, the optical information reader 100 can firmly attach the detachable part 90 to the main body part 98.

[0135] The detachable portion 90 has a first fitting portion 91 and a second fitting portion 92. The first fitting portion 91 fits into a portion of the second main surface 20 that corresponds to the display portion 11. The second fitting portion 92 fits into a portion of the second main surface 20 that corresponds to the key arrangement portion 12. The finger insertion space 29 is located between the first fitting portion 91 and the second fitting portion 92. The finger insertion space 29 is located between the first fitting portion 91 and the second fitting portion 92, so that the stability of the optical information reader 100 can be improved.

[0136] The second fitting portion 92 may be, for example, the battery fitting portion 92 or may be provided at a position different from the battery fitting portion 92.

[0137] The finger insertion space 29 is a (closed) space that intersects with the predetermined direction C and completely surrounds the periphery in a direction along the display unit 11. Since the finger insertion space 29 is a closed space, the stability of the optical information reader 100 can be improved.

[0138] The housing 8 further has a storage section 22 provided on the second main surface 20. The storage section 22 stores the imaging section 4. The finger insertion space 29 is surrounded by the storage section 22 on the predetermined direction C side.

[0139] Other examples of the finger insertion space 29 will be described below with reference to Fig. 18 and Fig. 19. Fig. 18 is a perspective view of the optical information reader 100 with the finger insertion space 29 open, viewed from the side above. Fig. 19 is a perspective view of the optical information reader 100 with the finger insertion space 29 located near the trigger 6, viewed from the side above.

[0140] 18, finger insertion space 29 is not a closed space, but a space that is open in predetermined direction C. That is, finger insertion space 29 is not enclosed on the predetermined direction C side.

[0141] Since the finger insertion space 29 is an open space, it is possible to insert a finger into the finger insertion space 29 from the opened predetermined direction C. Therefore, the optical information reader 100 can easily be switched from operating the trigger 6 to operating the key arrangement section 12.

[0142] The storage section 22 on the predetermined direction C side from the finger insertion space 29 is made small so as not to close the finger insertion space 29, and is disposed at the end of the housing 8 on the predetermined direction C side.

[0143] 19, the grip portion 30 has an extension member 33 that is a member that extends toward the housing 8. The extension member 33 closes the insertion space 29 on the side of the predetermined direction C. The trigger 6 is disposed on the extension member 33.

[0144] With the above-described configuration, the finger insertion space 29 is located near the trigger 6. Therefore, the optical information reader 100 can be easily switched from operating the trigger 6 to operating the key arrangement section 12.

[0145] The optical information reader 100 that is easy to carry will be described below with reference to Fig. 20. Fig. 20 is a side view of the optical information reader 100.

[0146] Before describing the optical information reader 100 shown in FIG. 20, the problems with conventional optical information readers will be described.

[0147] In conventional optical information readers, the end of the grip 30 is either empty or has a member that cannot be used to hook fingers. As a result, when carrying a conventional optical information reader, the end of the grip 30 cannot be used to hook fingers, requiring both hands, which is inconvenient for users. In other words, conventional optical information readers have the problem of being difficult to carry. The technical concept of the optical information reader 100 shown in FIG. 20 solves this problem.

[0148] 20, the optical information reader 100 further includes a folded portion 31. The folded portion 31 is provided on the opposite side of the grip portion 30 from the housing 8. The folded portion 31 forms an acute angle θ with the grip portion 30.

[0149] The folded portion 31 forms an acute angle θ with respect to the grip portion 30, so that fingers can be hooked on the folded portion 31. Therefore, the optical information reader 100 can be easily carried.

[0150] The folded portion 31 forms an acute angle θ with the grip portion 30 means that the axis 31A of the folded portion 31 and the axis 30A of the grip portion 30 form the acute angle θ. The axis 31A of the folded portion 31 is the centroid of the cross section of the folded portion 31. The axis 30A of the grip portion 30 is the centroid of the cross section of the grip portion 30.

[0151] It is not necessary for the entire folded portion 31 to form an acute angle θ with the grip portion 30; it is sufficient if only a part of the folded portion 31 (preferably the tip portion 32 of the grip portion 30) forms the acute angle θ with the grip portion 30.

[0152] The optical information reader 100 having the folding unit 31 described above is not limited to a handheld terminal, but also includes a handheld scanner. A handheld scanner does not have the display unit 11 and the key arrangement unit 12. That is, the optical information reader 100 including a handheld scanner has the following features.

[0153] "An optical information reading device that captures an image of a symbol to be read and reads information about the imaged symbol, an imaging unit that captures an image in a predetermined direction; a reading unit that reads information about the symbol from an image captured by the imaging unit; a housing in which the imaging unit and the reading unit are disposed; a grip portion provided on the housing; a trigger provided on the gripping portion, the trigger starting image capture by the image capture unit when the trigger is pushed in a pushing direction that is the opposite direction to the predetermined direction; a folded portion provided on the opposite side of the housing in the grip portion; Furthermore, The folded portion forms an acute angle with the gripping portion. <Embodiment 3>

[0154] Hereinafter, an optical information reader 100 according to a third embodiment of the present invention will be described with reference to the drawings. First, an outline of the optical information reader 100 according to the third embodiment will be described with reference to Fig. 21. Fig. 21 is a perspective view of the optical information reader 100 according to the third embodiment as viewed from below.

[0155] 21, the optical information reading device 100 captures an image of a symbol S to be read and reads information from the captured symbol S. The optical information reading device 100 includes an imaging unit 4, a reading unit 5, and a housing 8.

[0156] The imaging unit 4 captures an image in a predetermined direction C. The reading unit 5 reads information on the symbol S from the image generated by the imaging unit 4. The imaging unit 4 and the reading unit 5 are disposed inside the housing 8. The housing 8 has a first main surface 10 having a display unit 11 that displays information, and a second main surface 20 opposite the first main surface 10.

[0157] The optical information reader 100 further includes a grip unit 30, a push button 6, a first light-emitting unit 101, and a control unit 7. The grip unit 30 extends from an end 11E of the display unit 11 on the opposite side of the predetermined direction C. When the push button 6 is pressed in a pressing direction P, the imaging unit 4 starts capturing an image.

[0158] The first light-emitting unit 101 is provided on at least one of the side surfaces 64, 66 connecting the first main surface 10 and the second main surface 20, and the second main surface 20. The control unit 7 causes the first light-emitting unit 101 to emit light based on the status of reading by the reading unit 5.

[0159] In the optical information reading device 100, the first light-emitting unit 101 is provided on the side surface 64, 66 and / or the second main surface 20, so that the user can grasp the reading status even when in a position where the user cannot see the first main surface 10.

[0160] 21 is provided on the second main surface 20. The grip portion 30 provided on the second main surface 20 extends from an end 11E of the display unit 11 on the opposite side of the predetermined direction C. In other words, the grip portion 30 faces the end 11E of the display unit 11 on the opposite side of the predetermined direction C.

[0161] The optical information reader 100 does not need to include the grip portion 30 shown in Fig. 21. In such an optical information reader 100, the periphery of the key arrangement portion 12 becomes the portion to be gripped (i.e., the grip portion), as shown in Fig. 13, for example. The periphery of the key arrangement portion 12 (the grip portion) also extends from the end portion 11E of the display portion 11 on the opposite side of the predetermined direction C. In other words, the periphery of the key arrangement portion 12 (the grip portion 30) also faces the end portion 11E of the display portion 11 on the opposite side of the predetermined direction C.

[0162] 21, the first light-emitting unit 101 is located on the side of the grip unit 30 in the predetermined direction C. By being located on the side of the grip unit 30 in the predetermined direction C, the first light-emitting unit 101 is less likely to be hidden by the hand holding the grip unit 30. Therefore, the optical information reading device 100 can easily grasp the reading status.

[0163] The first light-emitting unit 101 is provided on the side surfaces 64, 66 that connect the first main surface 10 and the second main surface 20. Since the first light-emitting unit 101 is provided on the side surfaces 64, 66, the optical information reading device 100 allows the user to grasp the reading status even when in a position where the user cannot see the first main surface 10 and the second main surface 20.

[0164] The side surfaces 64, 66 on which the first light-emitting unit 101 is provided include the side surface 64 in the predetermined direction C and the side surface 66 in a direction perpendicular to the predetermined direction C and along the display unit 11. In order to improve visibility, the first light-emitting unit 101 is preferably provided on the side surface 66 in a direction perpendicular to the predetermined direction C and along the display unit 11.

[0165] Each of the side surfaces 64, 66 may not be a single surface, but may be divided into a surface on the first main surface 10 side and a surface on the second main surface 20 side. In this case, the first light-emitting portion 101 is preferably provided on the surface on the second main surface 20 side to improve visibility.

[0166] The first light-emitting unit 101 is provided on the second main surface 20. Since the first light-emitting unit 101 is provided on the second main surface 20, the optical information reading device 100 allows the user to grasp the reading status even when the user is in a position where the first main surface 10 and the side surfaces 64, 66 cannot be seen.

[0167] Next, the first light-emitting unit 101 will be described in detail with reference to Fig. 22 and Fig. 23. Fig. 22 is a perspective view of the optical information reader 100 as seen from the image-captured side and the second main surface 20 side. Fig. 23 is a rear view of the optical information reader 100 as seen from the second main surface 20 side.

[0168] 22, the first light-emitting unit 101 provided on the side surface 66 is positioned outward from the first main surface 10. The first light-emitting unit 101 positioned outward from the first main surface 10 can also be seen from the first main surface 10. Therefore, the optical information reader 100 can improve visibility.

[0169] The housing 8 further has a storage section 22 provided on the second main surface 20. The storage section 22 stores the imaging section 4. The second main surface 20 has a pair of steps 24. The pair of steps 24 reach the storage section 22 in both directions along the display unit 11, perpendicular to the predetermined direction C. The first light-emitting unit 101 is located at the pair of steps 24.

[0170] By positioning the first light-emitting unit 101 at the pair of steps 24, the arrangement of the first light-emitting unit 101 effectively utilizes the shape of the housing 8. Therefore, the optical information reader 100 can be made smaller.

[0171] 22 and 23, the first light-emitting units 101 provided on the side surfaces 66 are positioned in both directions along the display unit 11, perpendicular to the predetermined direction C. Therefore, as seen by a user holding the grip unit 30, the first light-emitting units 101 are positioned on the left and right sides of the housing 8. That is, if the user holds the grip unit 30 in his / her right hand, he / she can see the left first light-emitting unit 101, and if the user holds the grip unit 30 in his / her left hand, he / she can see the right first light-emitting unit 101. As a result, the optical information reading device 100 can easily grasp the reading status.

[0172] The inside of the housing 8 will be described below with reference to Fig. 24. Fig. 24 is a partially cutaway rear view in which the vicinity of the first light-emitting unit 101 in Fig. 23 is partially cut away.

[0173] 24, the first light-emitting unit 101 has a light-emitting element 111 and a diffusing member 110. The light-emitting element 111 emits light. The diffusing member 110 diffuses the light from the light-emitting element 111. Therefore, the optical information reading device 100 can improve visibility because the light emitted by the first light-emitting unit 101 is diffused light.

[0174] The surface of the diffusing member 110 that diffuses light is curved. The curved portion of the diffusing member 110 corresponds to the portion from the side surface 66 to the second main surface 20 of the housing 8. Therefore, the diffusing member 110 diffuses light efficiently. As a result, the optical information reader 100 can improve visibility.

[0175] The diffusion member 110 is made of, for example, rubber or resin such as plastic, etc. The diffusion member 110 is preferably milky white in order to further improve visibility.

[0176] The optical information reader 100 further includes a main board 107. The control unit 7 is mounted on the main board 107. The first light emitting units 101 are disposed on both ends of the main board 107.

[0177] The light-emitting element 111 of the first light-emitting unit 101 arranged at one end of the main substrate 107 and the light-emitting element 111 of the first light-emitting unit 101 arranged at the other end of the main substrate 107 emit light in directions away from each other.

[0178] With the above-described configuration, the optical information reader 100 can improve visibility even with a small number of light-emitting elements 111. Since the arrangement of the first light-emitting unit 101 on the main board 107 is restricted in order to accommodate electronic components such as an antenna, it is effective to be able to reduce the number of light-emitting elements 111 of the first light-emitting unit 101.

[0179] The main substrate 107 has a white member 112. The white member 112 is a portion onto which light from the light emitting element 111 is irradiated. By having the white member 112 on the main substrate 107, the light from the light emitting element 111 is reflected by the white member 112. Therefore, the optical information reader 100 can improve visibility.

[0180] The white member 112 is, for example, a white silk screen print. The white member 112 may be replaced with another member having a higher light reflectance than the white member 112.

[0181] White member 112 has one-end side white member 113 arranged at one end of main substrate 107, and other-end side white member 114 arranged at the other end of main substrate 107. One-end side white member 113 and other-end side white member 114 have shapes and areas such that the amount of light emitted by first light-emitting unit 101 is equal at one end and the other end of main substrate 107.

[0182] Therefore, the amount of light emitted by the first light emitting portion 101 is equal at one end and the other end of the main substrate 107. As a result, the optical information reader 100 can improve visibility.

[0183] The first light-emitting unit 101 has a plurality of light-emitting elements 111 (for example, light-emitting diodes). The plurality of light-emitting elements 111 included in one first light-emitting unit 101 each emit light of a different color. The first light-emitting unit 101 emits light of a different color at one end and the other end (asymmetric), but the amount of light emitted at one end and the other end can be made equal by adjusting the shape and area of ​​the white member 112.

[0184] Here, the fact that the light intensity at one end and the other end of the first light-emitting unit 101 is equal does not necessarily mean that the light intensity is exactly the same, but it is acceptable to the extent that the user perceives the light intensity as being the same.

[0185] The colors of light emitted from each of the plurality of light emitting elements 111 may be, for example, three colors such as the three primary colors of light (red, green, and blue), two colors, or four or more colors.

[0186] Hereinafter, a further configuration of the optical information reader 100 will be described with reference to Fig. 25. Fig. 25 is a partially cutaway perspective view of the optical information reader 100.

[0187] 25, the optical information reader 100 further includes a second light-emitting unit 102 provided on the first main surface 10. Therefore, the optical information reader 100 can improve visibility by using the first light-emitting unit 101 and the second light-emitting unit 102.

[0188] The optical information reading device 100 further includes a communication unit 117 capable of communicating with an external device G. The control unit 7 causes the first light-emitting unit 101 to emit light in response to communication from the external device G. Therefore, the highly visible first light-emitting unit 101 emits light in response to communication with the external device G. As a result, even if the optical information reading device 100 is lost, it can be easily found by having the external device G cause the first light-emitting unit 101 to emit light.

[0189] It is preferable that the control unit 7 also causes the second light-emitting unit 102 to emit light in response to communication from the external device G. Therefore, even if the optical information reading device 100 is lost, it can be easily found by having the external device G cause the first light-emitting unit 101 and the second light-emitting unit 102 to emit light.

[0190] The external device G is an external host or the like that can communicate with the communication unit 117. The external device G is not particularly limited as long as it is other than the optical information reader 100 and can communicate with the communication unit 117.

The scope of the present invention is indicated by the claims, not by the above description, and is intended to include all modifications within the meaning and scope equivalent to the claims. Of the configurations described in the embodiments, those other than those described as one aspect of the present invention in the "Means for Solving the Problems" are optional configurations and can be deleted or modified as appropriate.
