In addition, support 24 is provided with two

conveying rollers

22 and 23, and described support is spaced apart side part 26, the 26 ' formation that part 25 is fixed together by two.Two

conveying rollers

22 and 23 that are carved with the groove line in the axial direction have a gear 27 and 28 in each side, and described gear can mesh with tooth bar 14.In addition, a plurality of pin rods 29 that play axle effect are arranged between two side parts 26,26 ', and tape roll 30 is arranged on the pin rod rotatably.Pin rod 29 plays a part the attaching parts between distance piece and two the side parts 26,26 ' simultaneously.Support 24 is as plug-in card spare, thereby can change support after tape roll 30 is used up.Relative enclosure wall 3 ' is provided with a slightly crooked throw of lever 32 that has as the triangle cutter 33 of cutting member.The following rib 36 of the conduct control rocking bar of throw of lever 32 is resisted against on the boss 37 of gear 38, on the axle 39 of the enclosure wall 3 ' that described gear 38 is hubbed on equally.The inboard of gear 38 is provided with a pin rod 41, this pin rod utilize a tensioning spring 42 by pretension on another pin rod 43 of enclosure wall 3 '.When gear 38 breaks away from tooth bar 14 ' (Fig. 1), tensioning spring 42 retractions.When gear 38 is rotated about 180 ° by tooth bar 14 ' (Fig. 2), tensioning spring 42 is in the maximum tension state, and when gear 38 broke away from tooth bar 14 ', gear 38 returned its initial position (Fig. 1) again.

Shown in Fig. 3 to the guiding control of the adhesive tape (being shown in broken lines among the figure) of tape roll 30.Wherein, conveying

roller

22 and 23 passes through its gear 27 and 28 by tooth bar 14 clickwises, thereby makes adhesive tape 45 by the vertical warpage of 47 quilts of the warpage roller between two conveying rollers 22 and 23.Wherein, second conveying roller 23 has two annular grooves 48 (Fig. 4), therefore forms an annulus 49 in the centre.First conveying roller 22 only has an annular groove 51, and this annular groove cooperates with annulus 49 and slightly with overlap mode the latter covered.Warpage roller 47 has the annular protrusion 52 of a centre, makes adhesive tape 20 be converted into V-shape in the vertical.Can be clear that support 24 in Fig. 3, this support is for inserting the plug-in card spare structure in the casing 2.

Utilize the course of conveying of two

conveying rollers

22 and 23 shown in Fig. 5.Handle 8 is in initial position in Fig. 5 a, is promptly upwards pressed (arrow A) by pressure spring.Wherein, tooth bar 14 breaks away from the gear 27 and 28 of two conveying rollers 22 and 23.Because the L shaped side part 9 of handle 8 is positioned near the enclosure wall 3 that is omitted in the drawings, so part tooth bar 14 is shown in broken lines among the figure.When handle 8 is pushed downwards (Fig. 5 b), tooth bar 14 is placed and two gears 27 and 28 ingear states by rocking

bar

13 and 20, thereby makes conveying

roller

22 and 23 clickwises and adhesive tape 45 is carried.When handle 8 was pressed to the below fully, tooth bar 14 still kept and gear 27 and 28 engagements.Have only when handle 8 is released and is moved up by pressure spring, tooth bar 14 just and gear 27 and 28 break away from, promptly gear 27 and 28 stops operating and transferring adhesive tape 45 no longer.

Handle 8 by on (Fig. 5 a) when downwards (Fig. 5 c) is mobile, is then carried by the adhesive tape or the tape of conveying

roller

22 and 23 pairs of accurate fixed length.And can handle 8 be discharged, thereby tooth bar 14 and gear 27 and 28 are broken away from midway location (Fig. 5 b).When handle 8 is pushed once more, therefore long adhesive tape will be transferred out downwards.By repeatedly pushing the adhesive tape that can obtain random length.

Cutting process at length is shown in Fig. 6.Similar with tooth bar 14, the tooth bar 14 ' of this moment is moved down by handle 8.As shown in FIG., tooth bar 14 ' only has tooth at hypomere, and described tooth can mesh with gear 38.In nethermost position (Fig. 6 c), the tooth of tooth bar 14 ' meshes with gear 38 all the time, thereby tension spring 42 is strained fully.When this moment handle 8 is discharged, the throw of lever 32 that the gear 38 that then has a boss 37 continues clickwises and has a triangle cutter 33 is popped up, thereby makes 45 on adhesive tape be cut (Fig. 6 d).Because adhesive tape 45 is converted into V-arrangement by warpage roller 47 in advance.So on the band that is cut, form linear incision.If at this moment at midway location (Fig. 6 b) handle 8 is discharged, then throw of lever 32 can't be rebounded, and this is because gear 38 and boss thereupon 37 are rotated again, thereby causes band not to be cut.So, by conveying

roller

22 and 23 and the cooperation of not driven cutter 33 can determine from the length of the band of the shortest length (once pushing) beginning.Described identical with Fig. 5, tooth bar 14 ' also can all have tooth on whole length.On the other hand, tooth bar 14 and 14 ' also can be one-body molded with L type spare 9 and 9 ', wherein can save the pin rod 12 and first rocking bar 13.

Obviously, above-mentioned tape dispenser 1 is only by considerably less component set-up for the professional, thereby saved material widely and reduced cost.Another advantage of this tape dispenser 1 is use continuing such as the primary members such as casing 2 with handle 8 and cutting member 33, and the needs replacing only to be plug-in card spare or the support 24 that has tape roll 30.Thereby can further reduce the burden that environment is caused.Also can utilize again plug-in card spare or support 24 in addition.
