Description
本發明與手持式條碼掃描器有關，特別是指一種手持式條碼掃描器。 The present invention relates to hand-held bar code scanners, and more particularly to a hand-held bar code scanner.
目前在市面上的產品包裝上面都會印製有條碼，藉由一條碼掃描器的掃描且搭配一辨識系統的處理之後，即可將該條碼所代表的產品名稱、貨號，以及價格等產品資訊讀取出來，進而達到快速、方便且正確的自動化商品管理。 At present, barcodes are printed on the product packaging on the market.

為了詳細說明本發明之結構、特徵及功效所在，茲列舉三較佳實施例並配合下列圖式說明如後。 For a detailed description of the structure, features, and advantages of the present invention, three preferred embodiments are illustrated and described in conjunction with the following drawings.
請參閱第二及三圖，為本發明第一較佳實施例所提供之手持式條碼掃描器10，包含有一主機本體20、一握把30、一按鍵單元40，以及一磁性觸發單元50。 Referring to the second and third figures, a handheld barcode scanner 10 according to a first preferred embodiment of the present invention includes a main body 20, a grip 30, a button unit 40, and a magnetic trigger unit 50.
主機本體20的內部具有一驅動電路板22，在本實施例中，驅動電路板22的表面設置有一導電彈片24，當導電彈片24受壓至與驅動電路板22形成電性導通時，驅動電路板22即可驅動一掃描單元(圖中未示)進行掃描動作。 The main body of the main body 20 has a driving circuit board 22. In the embodiment, the surface of the driving circuit board 22 is provided with a conductive elastic piece 24. When the conductive elastic piece 24 is pressed to be electrically connected to the driving circuit board 22, the driving circuit is driven.

握把30以其頂端可分離地連接於主機本體20之底 面，用以方便使用者握持來操控主機本體20進行掃描動作，同時握把30的態樣亦可依照個人喜好或實際需要來進行更換，以提升更換握把30的靈活度。 The grip 30 is detachably coupled to the bottom of the main body 20 with its top end The surface is used to facilitate the user to control the main body 20 to perform the scanning operation, and the grip 30 can be replaced according to personal preference or actual needs, so as to improve the flexibility of replacing the grip 30.
按鍵單元40具有一按鍵41及一擺臂42。按鍵41以其一端藉由一樞軸412樞設於握把30，使得按鍵41可受外力按壓而以樞軸412為中心產生偏轉，而且，按鍵41自其內側面突伸出一頂推部414；擺臂42在本實施例中具有一轉軸部422、一第一臂部424，以及一第二臂部426，其中，轉軸部422樞設於握把30，第一臂部424以其底端連接轉軸部422，第二臂部426以其頂端連接轉軸部422且與第一臂部424之間具有一夾角θ，此外，第二臂部426之底端具有一長槽428，用以供按鍵41之頂推部414可滑移地連接。藉此，當按鍵41受外力作用按壓時，擺臂42會受到按鍵41之頂推部414的推動而產生偏擺。 The button unit 40 has a button 41 and a swing arm 42. The button 41 is pivoted at one end thereof to the grip 30 by a pivot 412, so that the button 41 can be deflected by the external force to be deflected about the pivot 412, and the button 41 protrudes from the inner side thereof by a pushing portion. In this embodiment, the swing arm 42 has a shaft portion 422, a first arm portion 424, and a second arm portion 426, wherein the shaft portion 422 is pivotally mounted to the grip 30, and the first arm portion 424 is The bottom end is connected to the rotating shaft portion 422. The second arm portion 426 is connected to the rotating shaft portion 422 at its top end and has an angle θ with the first arm portion 424. Further, the bottom end of the second arm portion 426 has a long groove 428. The pushing portion 414 for the button 41 is slidably coupled. Thereby, when the button 41 is pressed by an external force, the swing arm 42 is pushed by the pushing portion 414 of the button 41 to generate a yaw.
磁性觸發單元50具有一第一磁鐵52、一第一感磁元件54，以及一容置座56。第一磁鐵52固定於擺臂42之第一臂部424的頂端，使得第一磁鐵52可隨著擺臂42同步作動；第一感磁元件54設於主機本體20內且被導電彈片24給頂抵住，在本實施例中，第一感磁元件54可為磁鐵、鐵片或其他能被磁力所吸引的物件；導電彈片可為金屬彈片或印有導電材料的塑膠彈片；容置座56固定於驅動電路板22之表面，用以供第一感磁元件54容設在內。 The magnetic trigger unit 50 has a first magnet 52, a first magnetic sensitive component 54, and a receiving seat 56. The first magnet 52 is fixed to the top end of the first arm portion 424 of the swing arm 42 such that the first magnet 52 can be synchronized with the swing arm 42; the first magnetic sensitive component 54 is disposed in the main body 20 and is given by the conductive elastic piece 24. In the embodiment, the first magnetic sensing component 54 can be a magnet, an iron piece or other object that can be attracted by a magnetic force; the conductive elastic piece can be a metal elastic piece or a plastic elastic piece printed with a conductive material; 56 is fixed to the surface of the driving circuit board 22 for receiving the first magnetic sensing element 54.
當使用者尚未按壓按鍵41時，如第三圖所示，第一感磁元件54與第一磁鐵52之間是相互錯開，所以第一感磁 元件54是被導電彈片24所頂抵著，此時的驅動電路板22並不會被驅動。一旦使用者按壓按鍵41之後，如第四圖所示，擺臂42會被按鍵41之頂推部414給推動而產生偏擺，在擺臂42偏擺的過程中會將第一磁鐵52帶動至與第一感磁元件54相互對應的位置，此時的第一感磁元件54會藉由第一磁鐵52的吸力來克服導電彈片24的彈力，並且將導電彈片24抵壓至與驅動電路板22形成電性導通，如此即完成驅動電路板22的觸發而可透過掃描單元進行掃描動作。 When the user has not pressed the button 41, as shown in the third figure, the first magnetic sensitive element 54 and the first magnet 52 are mutually staggered, so the first magnetic field is The element 54 is abutted against the conductive elastic piece 24, and the drive circuit board 22 at this time is not driven. Once the user presses the button 41, as shown in the fourth figure, the swing arm 42 is pushed by the pushing portion 414 of the button 41 to generate a yaw, and the first magnet 52 is driven during the yaw of the swing arm 42. To the position corresponding to the first magnetic sensitive element 54, the first magnetic sensitive element 54 at this time overcomes the elastic force of the conductive elastic piece 24 by the suction force of the first magnet 52, and presses the conductive elastic piece 24 to the driving circuit. The board 22 is electrically connected, so that the triggering of the driving circuit board 22 is completed and the scanning operation can be performed through the scanning unit.
另一方面，在本實施例中，握把30內具有一擋壁32，擋壁32之表面設有一第二感磁元件34，例如磁鐵、鐵片或其他能被磁力所吸引的物件，此外，按鍵單元40更具有一第二磁鐵43及一彈性件44，第二磁鐵43設於按鍵41之內表面，彈性件44設於握把30之第二感磁元件34與按鍵單元40之第二磁鐵43之間，用以提供彈力將第二感磁元件34與第二磁鐵43相互分離。在按鍵41受按壓時，如第四圖所示，握把30之第二感磁元件34與按鍵單元40之第二磁鐵43會相互吸引，並且在吸引的過程中壓縮彈性件44，如此可以讓使用者以手部按壓按鍵單元40時有明確的按壓感受。當然，握把30之第二感磁元件34、按鍵單元40之第二磁鐵43，以及按鍵單元40之彈性件44可依實際需要而不設置。 On the other hand, in the present embodiment, the grip 30 has a retaining wall 32 therein, and the surface of the retaining wall 32 is provided with a second magnetic sensitive component 34, such as a magnet, an iron piece or other object that can be attracted by a magnetic force. The button unit 40 further has a second magnet 43 and an elastic member 44. The second magnet 43 is disposed on the inner surface of the button 41. The elastic member 44 is disposed on the second magnetic component 34 and the button unit 40 of the grip 30. The second magnets 43 are provided to provide elastic force to separate the second magnetic sensitive element 34 from the second magnet 43. When the button 41 is pressed, as shown in the fourth figure, the second magnetic sensitive component 34 of the grip 30 and the second magnet 43 of the key unit 40 are attracted to each other, and the elastic member 44 is compressed during the suction process, so that The user has a clear pressing feeling when the button unit 40 is pressed by the hand. Of course, the second magnetic sensitive component 34 of the grip 30, the second magnet 43 of the button unit 40, and the elastic member 44 of the button unit 40 can be disposed without actual needs.
然而，本發明之結構可有不同的變化，如第五圖所示，本發明第二較佳實施例所提供之擺臂66同樣具有一第一 臂部662及一第二臂部664，但省略轉軸部的設計，第一臂部662之頂端供第一磁鐵52固定，第二臂部664自第一臂部662之底端傾斜地延伸而出且以其末端與按鍵64之內側面形成連接。藉此，當按壓按鍵64之後，如第六圖所示，擺臂66會隨著按鍵64之樞轉而產生偏擺，並在偏擺的過程中將第一磁鐵52帶動至與第一感磁元件54相互對應的位置，此時的第一感磁元件54同樣會藉由第一磁鐵52的吸力來克服導電彈片24的彈力，並且將導電彈片24抵壓至與驅動電路板22形成電性導通，藉以完成驅動電路板22的觸發動作。 However, the structure of the present invention may have different variations. As shown in the fifth figure, the swing arm 66 provided by the second preferred embodiment of the present invention also has a first The arm portion 662 and the second arm portion 664 are omitted, but the design of the shaft portion is omitted. The top end of the first arm portion 662 is fixed to the first magnet 52, and the second arm portion 664 is obliquely extended from the bottom end of the first arm portion 662. And the end thereof is connected to the inner side surface of the button 64. Thereby, after pressing the button 64, as shown in the sixth figure, the swing arm 66 will yaw with the pivoting of the button 64, and drive the first magnet 52 to the first sense during the yaw. The position of the magnetic element 54 corresponding to each other, the first magnetic sensitive element 54 at this time also overcomes the elastic force of the conductive elastic piece 24 by the suction force of the first magnet 52, and presses the conductive elastic piece 24 to form electricity with the driving circuit board 22. The conduction is performed to complete the triggering action of the driving circuit board 22.
再如第七圖所示，本發明第三較佳實施例所提供之握把82的擋壁822設置一金屬彈片(Metal Dome)84來取代第一實施例中所採用的第二感磁元件34，按鍵86之內側面具有二頂推部862，864，其中一頂推部862用以頂抵擺臂88之第二臂部882的底端，另外一頂推部864用以抵壓金屬彈片84，此外，第一感磁元件92在本實施例中採用霍爾感測器而與驅動電路板80形成電性連接，用以感測第一磁鐵90的位置。藉此，當尚未按壓按鍵86時，如第七圖所示，第一感磁元件92可以感測到第一磁鐵90的位置，所以不會產生任何訊號至驅動電路板80，一旦按壓按鍵86之後，擺臂88會被按鍵86之頂推部862給推動而產生偏擺，如第八圖所示，並在偏擺的過程中將第一磁鐵90移動至第一感磁元件92所無法感測到的位置，此時的第一感磁元件92便會傳輸訊號至驅動電路板80來完成觸發動作。 另一方面，在按鍵86樞轉的過程中，按鍵86之頂推部864會逐漸抵壓金屬彈片84，直到將金屬彈片84抵壓至與握把82之擋壁822的表面產生接觸為止，以達到增加按壓手感的效果。當然，握把82之金屬彈片84與按鍵86之頂推部864可依照實際需要而不設置。 As shown in the seventh embodiment, the retaining wall 822 of the grip 82 provided in the third preferred embodiment of the present invention is provided with a metal dome 84 instead of the second magnetic component used in the first embodiment. 34, the inner side of the button 86 has two pushing portions 862, 864, wherein a pushing portion 862 is used to abut the bottom end of the second arm portion 882 of the swing arm 88, and another pushing portion 864 is used for pressing the metal The elastic piece 84, in addition, the first magnetic sensitive element 92 is electrically connected to the driving circuit board 80 in the present embodiment by using a Hall sensor for sensing the position of the first magnet 90. Thereby, when the button 86 has not been pressed, as shown in the seventh figure, the first magnetic sensitive component 92 can sense the position of the first magnet 90, so no signal is generated to the driving circuit board 80, once the button 86 is pressed. Thereafter, the swing arm 88 is pushed by the pushing portion 862 of the button 86 to generate a yaw, as shown in the eighth figure, and the first magnet 90 is moved to the first magnetic sensor 92 during the yaw. The sensed position, at this time, the first magnetic sensitive component 92 transmits a signal to the drive circuit board 80 to complete the triggering action. On the other hand, during the pivoting of the button 86, the pushing portion 864 of the button 86 gradually presses the metal dome 84 until the metal dome 84 is pressed against contact with the surface of the retaining wall 822 of the grip 82. In order to increase the effect of pressing the hand. Of course, the metal dome 84 of the grip 82 and the pushing portion 864 of the button 86 can be disposed according to actual needs.
綜上所陳，本發明之手持式條碼掃描器利用磁效應來作為觸發動作的設計，可以讓主機本體與握把之間不需要開設出相互對應的穿孔，以確實達到增加結構強度及提升防水性的目的。 In summary, the hand-held barcode scanner of the present invention utilizes the magnetic effect as a triggering action design, so that there is no need to open corresponding punches between the main body and the grip to achieve an increase in structural strength and waterproofing.
