Description

  The present invention relates to an optical information reader.

  A bar code handy terminal is known as a typical example of an optical information reader. A barcode handy terminal, which is a portable optical information reader, is used for reading a barcode attached to a product or its packaging box in a factory, a warehouse, or the like. The bar code handy terminal emits a laser beam, scans the bar code with this laser beam, reads it, and displays the reading result on the display.

  The optical information reading device disclosed in Patent Document 1 includes an inner frame and a substrate that are installed inside the front case and the rear case constituting the housing. When the rear case is viewed from above, the board is first installed in the rear case, and then the internal frame is installed thereon. Patent Document 1 proposes forming a buffer rib on the rear case in order to protect the display attached to the inner frame. The buffer rib elastically supports the inner frame when a force that pushes down the display incorporated in the inner frame, that is, a force that displaces the display in the direction of the rear case, acts on the display.

JP 2009-63802 A

  In conventional portable optical information readers, a sufficient clearance is generally set between the ceiling or side wall of the rear case and the internal frame. However, when the optical information reader drops from its side or top surface at a speed higher than expected, even if a sufficient clearance is set, the internal frame is displaced or deformed by the impact, and the display is passed through the internal frame. The structure included the possibility of impact. In particular, at a work site such as a warehouse where the optical information reader is used, an operator working at a high place may accidentally drop the optical information reader. Depending on the collision speed and the location of the collision, there is a risk of causing a display failure.

  An object of the present invention is to provide an optical information reading apparatus capable of protecting a display from an impact when an impact is applied to the optical information reading apparatus.

  It is a further object of the present invention to provide an optical information reader capable of protecting a display from an impact when an impact is applied to the side wall of the optical reader.

By installing the battery pack 28 in the battery receiving recess 29 of the rear case 21, the battery pack 28 is connected to the battery terminal board 27 of the barcode handy terminal 100. The barcode handy terminal 100 is driven by the electric energy of the battery pack 28 that is electrically connected.

  A terminal window 31 is formed at the lower end of the rear case 21, and the terminal board 33 incorporated in the terminal holder 32 is attached to the lower end of the rear case 21 so as to face the terminal window 31. Terminals (not shown in the drawing for drawing reasons) provided in the terminal holder 32 are exposed to the outside through the terminal window 31, and are connected to the outside through the terminal window 31 through a cradle 34 (FIG. 20) described later. The battery pack 28 can be charged by the charging units 95 and 96 (FIG. 20). Reference numeral 36 in FIG. 2 indicates a terminal holder tape.

  A battery terminal pressing member 42 is installed on the rear case 21 via a battery protection tape 40 and a battery terminal cushion 41 in association with the battery terminal board 27, and the battery terminal pressing member 42 is screwed to the rear case 21. Thus, the battery terminal holding member 42 restricts the terminal portion 27a of the battery terminal board 27 from being displaced away from the rear case 21. A vibrator 44 is disposed on the side of the battery terminal board 27, and the vibrator 44 is attached to the rear case 21.

  A scanner filter 46 is attached to the reading window 25 of the rear case 21 from the outside of the rear case 21. On the other hand, a scanner holder 48 attaches an O-ring 49 to the rear case 21 via a rear cushion 47 inside the rear case 21. Screwed through.

  A scanner module 50 is mounted on the scanner holder 48. The laser light emitted from the scanner module 50 is guided to the reading window 25 and the light returning from the barcode attached to the object is guided to the scanner module 50. A reflection mirror 51 is assembled to the scanner holder 48.

  The scanner module 50 includes a semiconductor laser light emitting element, a photodiode as a light receiving element, a galvano mirror, a scanner substrate, and the like, as in the prior art, and oscillates laser light emitted from the semiconductor laser light emitting element at a predetermined cycle. The light is reflected by the galvanometer mirror and emitted toward the bar code through the reading window 25, and the bar code is scanned. The light returned from the bar code is taken into the scanner module 50 and received by the photodiode. When the photodiode receives light, the received light signal is amplified by the light receiving circuit and the amplifier circuit of the scanner substrate. The scanner substrate is provided with a mirror driving circuit, and the galvano mirror is driven by the mirror driving circuit, and the galvano mirror performs the above-described swinging motion.

  Reference numeral 53 in FIG. 2 indicates a first scanner cushion. The scanner cushion 53 is disposed in front of the scanner holder 48, and the scanner cushion sheet metal 54 positioned in front of the scanner cushion 53 is screwed to the scanner holder 48.

  A second scanner cushion 55 is positioned in front of the scanner cushion metal plate 54, and a main board 57 is disposed in front of the second scanner cushion 55. The main board 57 has almost the same size as the LCD 10 described above, and the main board 57 is provided with a main circuit having a relatively large circuit scale including a control CPU and a memory. The overall control and the reading process of the acquired barcode are performed, the reading result is stored in a memory (not shown), and a signal to be displayed on the LCD 10 is generated.

  The main board 57 is fixed to the scanner holder 48 using a screw common to the LCD holder 60 positioned in front of the main board 57. That is, the LCD holder 60 is screwed to the scanner holder 48 with the main board 57 sandwiched therebetween. The LCD 10 is tightly fitted to the LCD holder 60.

  In other words, in the present embodiment, the LCD holder 60 is fixed to the scanner holder 48 so that the main board 57 is interposed, and the scanner holder 48 is fixed to the rear case 21. As described above, in this embodiment, the LCD holder 60 is fixed to the rear case 21 via the scanner holder 48, but the present invention is not limited to this, and may be directly fixed to the rear case 21, or You may fix to the front case 20 facing the rear case 21. That is, it may be fixed directly or indirectly to the casing of the barcode handy terminal 100.

  A key board 61 is disposed below the main board 57, and a main key top 62 in front of the key board 61 is screwed to the key board 61. The main key top 62 is provided with the above-described operation unit 11, that is, the menu key 12, the trigger key 13, the numeric keypad group 17 and the like (FIG. 1).

  The front case 20 is assembled to the rear case 21 incorporating the above-described components via the main packing 22 described above. Prior to this, an LCD front cushion 63 is disposed in the peripheral portion of the LCD 10, and this LCD front cushion. The LCD 10 is pressed by the front case 20 by 63. The front case 20 is assembled with a light transmissive front panel 64 and a front seat 65 on the front surface thereof.

  FIG. 3 is a perspective view of the above-described LCD holder 60 viewed obliquely from the front, and FIG. 4 is a front view thereof. The LCD holder 60 is a synthetic resin molded product. The LCD holder 60 has a rectangular frame shape in plan view, a side member 66 that is a pair of frame structural elements located on the left and right side edges thereof, that is, a member 66 that extends along the left and right side walls of the front case 20, The cross member 85 which is a frame component which connects the upper end parts of the side member 66 is included. By connecting the ends of the side members 66 to each other with the cross member 85, it is possible to suppress displacement in the direction in which the side members 66 approach each other when subjected to an external impact. The pressure applied to the display from the member 66 can be reduced.

  The side member 66 is provided with a plurality of elastic protrusions 67 spaced apart in the longitudinal direction on the outer surface thereof. In addition, two inner protrusions 68 that protrude toward the center of the LCD holder 60 are formed on each side member 66 on the inner side surfaces of the pair of side members 66. The inner protrusion 68 fixes the LCD 10. In the embodiment, two independent standing walls 69 are formed in the longitudinal direction of each side member 66, and the inner protrusion 68 is formed on the standing wall 69. Is formed. When the LCD 10 is mounted on the LCD holder 60, the upright wall 69 is elastically deformed, and the LCD 10 is detachably fixed by the inner protrusion 68 by the elastic force.

  The elastic protrusion 67 extending in the lateral direction from the side member 66 toward the side wall of the front case 20 is configured by a rib extending inclined with respect to the vertical direction of the side wall of the front case 20. In other words, the elastic protrusion 67 of this embodiment is configured by a rib that is inclined at an angle of less than 90 ° with respect to the longitudinal axis of the side member 66 and extends outward. When the LCD holder 60 is attached to the rear case 21 (via the scanner holder 48), the tip of the elastic protrusion 67 is in pressure contact with the side wall of the front case 20, and the elastic protrusion 67 is slightly bent and deformed. Thereby, for example, when a person who operates the barcode handy terminal 100 drops the barcode handy terminal 100, for example, the shock when the barcode handy terminal 100 is dropped from the side surface of the barcode handy terminal 100 is absorbed by the deformation of the elastic protrusion 67. Can do. Thereby, it is possible to reduce the transmission of the impact from the LCD holder 60 to the LCD 10.

  5 to 7 exemplify modified examples of the elastic protrusion 67. The elastic projection 70 of the first modification shown in FIG. 5 extends from the side member 66 once in the vertical direction and then bends to extend parallel to the longitudinal axis of the side member 66, and then toward the side member 66. The front end surface of the front case 20 is in pressure contact with the side wall of the front case 20. The elastic protrusion 71 of the second modification shown in FIG. 6 has an elliptical shape in plan view. The elastic protrusion 72 of the third modified example shown in FIG. 7 has a shape obtained by notching the tip portion of the elliptical elastic protrusion 71 of the second modified example. As can be seen from the elastic protrusions 70 to 72 of the first to third modifications and the elastic protrusion 67 included in the embodiment, the side wall of the front case 20 is elastically contacted by bending deformation and / or elasticity of physical properties. Of course, any shape can be adopted as long as it is a projection that can be applied, but it may be a projection that can elastically contact the side wall of the front case 20 with springy physical properties.

  Further, in the present embodiment, since a plurality of elastic protrusions 67 and 70 to 72 are formed apart from each other in the longitudinal direction of the side member 66, the weight of the entire elastic protrusion is reduced (and consequently the bar code handy terminal 100 is reduced in weight). The shock absorption can be performed with good balance in the longitudinal direction of the side member 66. However, the present invention is not limited to this, and a single elastic protrusion having an arbitrary shape may be formed at a predetermined position of the side member 66. Further, in this embodiment, the elastic protrusion is formed by extending a part of the side member 66, but a configuration in which the elastic protrusion is attached to the side member 66 as a separate member is also conceivable. .

  The assembly of the scanner module 50 will be described with reference to FIGS. 8 and 9 are partial views of the upper end portion of the rear case 21, that is, the portion where the scanner module 50 is disposed as viewed from above. Referring to FIG. 8, two struts 74 arranged diagonally are formed on the upper end portion of rear case 21, and screw holes that are open upward are formed on the upper end surface thereof. Prior to assembling the scanner holder 48, the O-ring 49 described above is placed on the upper end surface of the column 74, and the scanner holder 48 is placed thereon. As can be seen from FIG. It is fixed to the column 74, that is, the rear case 21 by a screw 76. In the figure, reference numeral 77 denotes a washer interposed between the scanner holder 48 and the screw head of the screw 76.

  A plurality of screw holes are formed in the front surface of the scanner holder 48, and three first screw holes 78 (FIG. 9) spaced from each other so as to cover the scanner module 50 are used to connect the second scanner cushion 55 to the scanner. The scanner holder 48 is formed to be fixed to the front surface of the holder 48 with screws 79 (FIG. 10). As can be seen from FIG. 10, the second scanner cushion 55 has a size that can cover almost the entire area of the front surface of the scanner holder 48.

  On the front surface of the scanner holder 48, second screw holes 80 (FIG. 9) are formed at the four corners, and four screws 81 (FIG. 11) to be screwed into the four screw holes 80 are provided as main parts. The main board 57 and the LCD holder 60 are rigidly fixed to the scanner holder 48 by inserting predetermined openings of the board 57 and the LCD holder 60. That is, the LCD holder 60 and the main board 57 are fastened to the scanner holder 48 by the common screw 81 in a state where the main board 57 is sandwiched between the scanner holder 48 and the LCD holder 60. As a result, as shown in FIGS. 18 and 19, the scanner holder 48, the main substrate 57, and the LCD holder 60 are integrated. Thereby, not only the impact absorption to the LCD holder 60 but also the impact absorption to the scanner holder 48 and the impact absorption to the main board 57 can be performed simultaneously.

  The LCD 10 accommodated in the LCD holder 60 is connected to the main substrate 57 by the flexible substrate 10a (FIGS. 12 and 18) as in the conventional case, and the scanner module 50 accommodated in the scanner holder 48 is similar to the conventional case. It is connected to the main board 57 by another flexible board. Since the scanner holder 48 is fixed to the rear case 21 via the O-ring 49 as described above, the elastic protrusions 67 and 70 to 72 (FIGS. 3 and 5 to 7) described above are not necessarily included in the front case. It is not necessary to be in pressure contact with the 20 side walls. When the LCD holder 60 is assembled to the rear case 21, the elasticity 67, 70 to 72 may be in contact with the side wall of the front case 20. Thereby, the assembly ease at the time of assembling the LCD holder 60 to the rear case 21 can be improved. It may be in a state slightly separated from the side wall of the front case 20 (FIG. 12).

  The main board 57 can be substantially integrated with the scanner module 50 by fixing the main board 57 rigidly to the scanner holder 48 containing the scanner module 50. Therefore, even if the impact when the barcode handy terminal 100 is dropped or handled roughly is input to the rear case 21, the scanner module 50 and the main board 57 behave substantially in the same manner. The load applied to the terminal portion 83a that electrically connects the flexible substrate 83 (FIG. 2) extending from the scanner holder 48 can be reduced. Therefore, wear of the terminal portion 83a can be prevented.

  FIG. 13 is a vertical cross-sectional view of the upper end portion of the barcode handy terminal 100, that is, the portion where the scanner module 50 is mounted, and is a view of the LCD 10 facing down. It is desirable to take measures to avoid damaging the LCD 10 when dropped in this state. As described above, since the LCD front cushion 63 (FIGS. 13 and 2) is interposed between the LCD 10 and the front case 20, the LCD front cushion 63 can absorb an impact.

  In addition, since the main board 57 located behind the LCD holder 60 is fixed to the rear case 21 via the scanner holder 48, the electronic components mounted on the main board 57 are prevented from applying a load to the LCD 10 due to an impact. it can. In addition to this, referring to FIG. 13, the height dimension H1 of the cross member 85 extending in the transverse direction at the end of the LCD holder 60 is set larger than the thickness dimension H2 of the LCD 10 (H1> H2). ). Thus, when the LCD 10 is fitted in the LCD holder 60 and the LCD 10 is attached to the normal position of the LCD holder 60, the reference symbol G in FIG. 13 indicates the front case 20 side end and the LCD 10 in the height direction of the cross member 85. The gap between the surfaces of the By providing this gap G, it is possible to prevent an impact from being applied directly to the LCD 10 when the barcode handy terminal 100 is dropped from the front side.

  FIG. 14 is a cross-sectional view showing a portion of the rear case 21 to which the battery terminal board 27 is attached. As described above, the battery terminal board 27 (FIG. 2) is attached to the middle portion in the longitudinal direction of the rear case 21. When the barcode handy terminal 100 falls with the LCD 10 facing down, the terminal portion of the battery terminal board 27 is placed. 27a behaves in a direction away from the rear case 21. Therefore, as described above, the terminal portion 27a is fixed in position by the battery terminal pressing member 42. With reference to FIG. 2, the battery terminal pressing member 42 has a shape surrounding the terminal portion 27 a from above, and the battery terminal pressing member 42 is screwed to the rear case 21. As can be clearly seen from FIG. 14, the battery terminal pressing member 42 has not only the terminal portion 27a but also an end for supporting the end of the battery pack 28 engaged with the terminal portion 27a. The terminal part 27a and the end of the battery pack 28 can be supported by the battery terminal pressing member 42 against an impact when the handy terminal 100 is dropped.

  15 and 16 are partial cross-sectional views of different portions of the barcode handy terminal 100 cut along the transverse direction. As described above, the LCD holder 60, the main board 57, and the scanner holder 48 are integrated by the screws 81. The integrated LCD holder 60, main board 57, and scanner holder 48 are fixed to the rear case 21 with screws 76 through the O-ring 49 (FIG. 2) (FIG. 9). A rear cushion 47 (FIG. 2) is interposed between the scanner holder 48 and the rear case 21. From this, it is possible for the rear cushion 47 and the O-ring 49 to suppress the impact from being transmitted to the entire integrated LCD holder 60, main board 57, and scanner holder 48. In addition, as shown in FIG. 16, the LCD holder 60 is attached to the rear case 21 with the end 60 a or the protrusion of the LCD holder 60 placed on the stepped portion 21 a formed on the side wall of the rear case 21. Is preferred. According to this, since the impact when the barcode handy terminal 100 drops from the back surface can be distributed to the LCD holder 60 in addition to the rear cushion 47 and the O-ring 49, the main board 57, The scanner holder 48 can be more reliably protected.

  When the barcode handy terminal 100 falls from its upper end surface, that is, the top surface, the main board 57 may interfere with the top wall of the rear case 21. Conventionally, the upper end face of the main board 57 is used as the top wall of the rear case 21. The measures to keep away from as much as possible were adopted. On the other hand, in the embodiment, the upper end surface of the main board 57 is designed to be as close as possible to the top wall of the rear case 21, and a slight gap between the upper end face of the main board 57 and the top wall of the rear case 21 is designed. A silicon rubber plate 87 is interposed as a cushioning material in the gap. The silicon rubber plate 87 has a flat shape, alleviates transmission of an impact caused by dropping of the barcode handy terminal 100 to the upper end surface of the main substrate 57, and suppresses relative displacement of the upper end surface of the main substrate 57. It is preferable to have a thickness that can fill a gap between the upper end surface of the main board 57 and the top wall of the rear case 21.

  A plurality of display LEDs 88 are mounted side by side on the upper end portion of the main board 57 shown in FIG. The light emitted from the display LED 88 causes the LED window 90 (FIG. 1) at the upper end of the front case 20 to emit light through an opening 89 formed at the upper end of the LCD holder 60 shown in FIG. An LED lens 91 is attached to the upper end opening 89 of the LCD holder 60 (FIG. 2), and the LED lens 91 is a molded product of silicon rubber.

  The LED lens 91 is a molded product of silicon rubber, and the LED lens 91 preferably has a shape including the silicon rubber plate 87 described above. That is, it is preferable that the silicon rubber plate 87 interposed between the upper end surface of the main substrate 57 and the top wall of the rear case 21 constitutes an extended portion of the LED lens 91.

  Since the silicon rubber plate 87 is interposed as a cushioning material in the slight gap between the upper end surface of the main board 57 and the top wall of the rear case 21 as described above (FIG. 17), the barcode handy terminal 100 is The impact when falling from the upper end surface, that is, the top surface can be absorbed by the silicon rubber plate 87. Further, since the size of the gap can be reduced as much as possible by interposing the cushion material, the entire barcode handy terminal 100 can be reduced in size.

  Referring to FIG. 20, the barcode handy terminal 100 according to the embodiment can communicate with the server 92 via the RS-232 cable 93 or the USB cable 94, and can communicate with the server 92 by being placed on the cradle 34. is there. The barcode handy terminal 100 can be charged without removing the battery pack 28 simply by being placed on the barcode handy terminal charging unit 95. Further, the battery pack 28 can be charged by removing the battery pack 28 from the barcode handy terminal 100 or placing the spare battery pack 28 in the battery pack charging unit 96. Furthermore, the dry battery pack 97 can be mounted on the barcode handy terminal 100.

  Although the barcode handy terminal 100 of the embodiment is applied to reading a one-dimensional code (so-called barcode), the present invention is not limited to the one-dimensional code. The present invention can also be suitably applied to an optical information reader that reads a matrix code such as a QR code or a two-dimensional code such as a stack code in which a plurality of one-dimensional barcodes are stacked one above the other. Accordingly, the “bar code” used in this specification and claims should be understood to have a broad meaning recognized by those skilled in the art, that is, a meaning including a one-dimensional code and a two-dimensional code, unless otherwise specified. .
