Abstract
Abstract An automatic adhesive transfer device using an adhesive tape is used to bond desired portions of paper or the like in offices, home, schools, etc. In the device, an adhesive tape roll, which is formed by winding an adhesive tape comprising a double-side release paper with an adhesive coating thereon, with the adhesive coated surface on the outer side, is loaded in a casing. In the use of the device, the adhesive tape roll can be rotated only in the direction of adhesive transfer and at a rotational speed suitable therefor. The device is thus not damaged by applying force to it in the opposite direction i.e., a rotation-blocked direction. In addition, it is possible to transfer the adhesive to a desired location accurately at all times.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
178 words
An automatic adhesive transfer device, comprising: a casing; adhesive tape comprising double-sided release paper in the form of an adhesive tape roll having an outer side surface coated with adhesive, said adhesive tape roll being rotatably mounted in said casing; said casing having a bottom having an opening exposing said outer side surface of said adhesive tape coated with adhesive and a top having an exit for discharging a used portion of said double-sided release paper; a ratchet mechanism including a ratchet mechanism member connected with one of said adhesive tape roll and said casing and a ratchet pawl engaging said ratchet mechanism member so as to allow rotation of said adhesive tape roll in only a direction of adhesive transfer connected with the other of said adhesive tape roll and said casing; and a tape cutter disposed adjacent to said exit, said tape cutter having an upper end cutter blade for cutting of said used portion of said double-sided release paper and an urging part urging said used portion of said double-sided release paper in said casing.
Claim 2
Dependent Claim
178 words
An automatic adhesive transfer device, comprising: a casing; adhesive tape comprising double-sided release paper in the form of an adhesive tape roll having an outer side surface coated with adhesive, said adhesive tape roll being rotatably mounted in said casing; said casing having a bottom having an opening exposing said outer side surface of said adhesive tape coated with adhesive and a top having an exit for discharging a used portion of said double-sided release paper; a ratchet mechanism including a ratchet mechanism member connected with one of said adhesive tape roll and said casing and a ratchet pawl engaging said ratchet mechanism member so as to allow rotation of said adhesive tape roll in only a direction of adhesive transfer connected with the other of said adhesive tape roll and said casing; and a tape cutter disposed adjacent to said exit, said tape cutter having an upper end cutter blade for cutting of said used portion of said double-sided release paper and an urging part urging said used portion of said double-sided release paper in said casing.
Claim 3
Dependent Claim
52 words
The automatic adhesive transfer device of claim 1, wherein said adhesive tape roll is mounted on and rotatable with a hollow adhesive tape roll core, said ratchet mechanism member is integral with said hollow adhesive tape roll core and said pawl projects from said casing into engagement with said ratchet mechanism member.
Claim 4
Dependent Claim
26 words
The automatic adhesive transfer device of claim 2, wherein said hollow adhesive tape roll core is rotatably mounted on a tape roll shaft on said casing.
Claim 5
Dependent Claim
38 words
The automatic adhesive transfer device of claim 2, wherein said hollow adhesive tape roll core has a plurality of ridges on an outer periphery thereof wedged into engagement with an inner peripheral surface of said adhesive tape roll.
Claim 6
Dependent Claim
32 words
The automatic adhesive transfer device of claim 2, wherein said casing has a recess having a peripheral surface from which said pawl projects, said ratchet mechanism member being received in said recess.
Claim 7
Dependent Claim
37 words
The automatic adhesive transfer device of claim 1, wherein said ratchet mechanism member has teeth on a peripheral surface thereof directed in one direction and said pawl is directed in a direction opposite to said one direction.
Claim 8
Dependent Claim
79 words
The automatic adhesive transfer device of claim 1, wherein said adhesive tape roll has an adhesive-free edge portion and a release paper discharging member is disposed in said casing downstream of said exit in the direction of rotation of said adhesive tape roll, said release paper discharging member being held in contact by gravity with said adhesive-free edge portion of said adhesive tape roll to prevent the used portion of said double-sided release paper from remaining in said casing.
Claim 9
Dependent Claim
