  • the staple guide plate 41 rotates through the link 43 about the pin 42 to close a bag receiving section 51.
  • the driver 49 withdraws and its wing 50 causes the pusher 44 to retreat against the force of the spring 48, whereby the staple guide plate 41 is rotated to open the bag receiving section 51.
  • the device according to the present invention is constructed and operated as described above and because of the wide opening in the bag receiving section, it makes it possible not only to smoothly insert and remove the bag thereinto and therefrom but also to keep the bag in the predetermined sealing position by holding the same by closing the staple guide plate.
  • the tracks of the staple guide groove which are parallel and straight enable the swift and light movement of the staple.
  • the opening and closing of the staple guide plate and the cutting-off and driving of the staple are all achieved by only rotating the operation handle, whereby the sealing operation is effected continuously and automatically.
  • the bag is perfectly water-tightly sealed by staple without being damaged by the projected inner edges of the staple guide plate and clincher arm plate during the inserting, sealing and removing operations.
  • FIG. 12 and other succeeding drawings illustrate still another embodiment of the staple magazine 6.
  • Reference numeral 61 designates a delivery hole provided by perforating square the body 2 above the driver groove 7 in order to send out the staple into the groove 7.
  • Item 63 is a magazine holder which is a resilient tubular body with a square cross-section and a longitudinal slot 64. The two adjoining sides of the holder 63 swell inwards to form small projections 65 and 65', while the lower end of one side thereof is extended and bent to form a fitting member 66 adapted to be fixed at one side of a hole 68 made, immediately above the delivery hole 61, in a guide plate 67 mounted on the body 2.
  • Item 69 is a chute-like magazine for accomodating staples, channel-shaped in section.
  • a staple guide 70 On its inside is provided a staple guide 70, which is also channel-shaped in section, with its one side 70 being fixed to one side 69 of the magazine 69 so that a bar of channel-shaped staples A may be accommodated in a space 71 between the magazine 69 and the staple guide 70.
  • the opposite lower ends of said magazine 69 are provided with channel-shaped notches 72 and 7 2, while the adjoining two sides of the same swell outwards, near the lower end, to form small projections 73 and 73 protruding outwards.
  • the magazine is installed in the following manner.
  • the magazine 69 is inserted from above into the magazine holder 63 until its tip reaches, beyond the small projections 65 and 65' and through the hole 68, the delivery hole 61 in the body 2, the notches 72 and 72 at the lower end of the magazine 69 come into engagement with the stop projections 62 and 62' in the delivery hole 61.
  • said small projections 65 and 65 and the small projections 73 and 73 on the magazine 69 exert such forces as to expand the magazine holder 63 so that the magazine 69 may be firmly held by the elasticity of the holder, thereby accomplishing the assembly.
  • the device can be made compact for carrying convenience because the magazine 69 is detachable from the body 2.
  • the magazine 69 When the magazine 69 is installed, the lower end thereof does not project into the driver groove 7 in such a manner as to prevent the operation of the driver 4, since it is engagedly disposed above the delivery hole 61.
  • the magazine holder 63 accurately guides the magazine 69 to the delivery hole 61, and the small projections on the holder 63 and magazine 69 expand the tubular holder so that the magazine 69 is firmly held due to the action of elasticity. So the magazine is securely engaged and held without coming off even if it is subjected to vibration or contact with any other article during the sealing operation.
  • the staple A is automatically supplied to the driver groove 7 without requiring the installation of any particular equipment, since it drops into place due to its own weight. Furthermore, it is possible to watch the consumption of staples, thereby preventing the blank driving, since one side of the magazine 69 is cut open. As is evident from the above, this invention offers various excellent results.
