Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a roll-up recording paper used in a recorder.

[Technical background of the invention and its problems] There is a recorder that reuses the used core as the core for winding the recorder when the recording paper is used up. If a fixing device is used to fix the starting end of the recording paper to the core, the fixing device is attached as an accessory to each roll of recording paper. However, there is a high risk of forgetting to attach the fixing tool or losing the powder on the user's side.

[Purpose of invention]

The object of the present invention is to provide a roll-up type recording paper that eliminates the problem of forgetting to attach a fixing device and the loss of powder on the user's side.

[Summary of the idea]

The present invention has a tubular shape, and has a pair of rotational force transmission notches cut into each end with a predetermined length and width from the end, and has a common plane that includes the center line of the circumferential width of each pair of notches. a winding core having a pair of slits formed in the center in the longitudinal direction and having a predetermined length and width symmetrically with the tube axis so that the center line of the width in the circumferential direction coincides with the plane; A pipe wall having a tubular shape having an inner diameter to fit in, having a length substantially equal to the winding core and having a predetermined central angle, has an opening cut out over the entire length of the pipe, and a plane that bisects the central angle of this opening. The center line of the width in the circumferential direction is located at the top, a notch is formed at both ends of the tube that is wider than the notch and approximately equal in length, and the center line in the longitudinal direction is wider than the slit. a fixing tool in which slits of approximately equal length are formed, and the fixing tool is placed over the core so that the notch and the slit are aligned with each other, so that the end portion of the recording paper is inserted into the slit of the fixing tool. Wrap the recording paper several times around the outer surface of the fixing device, passing through the slits of the opposing core and reaching the outer surface of the core, and fixing it to the combined body of the core and the fixing device. This is a roll-up type recording paper that is wound around a bonded body for a predetermined length.When manufacturing the recording paper, a fixing device is placed over the core and the recording paper is rolled up as part of the core. There is no need to forget to attach the fixing device, and when the recording paper is used up, the fixing device and core come out combined, so there is no chance of powder being lost.

[Example of idea]

Embodiments of the present invention will be described below with reference to the drawings.

An embodiment of the roll-up type recording paper according to the present invention is shown in FIGS. 1 and 2. In FIG. 1, the winding core 1 has a tubular shape, and a pair of rotational force transmission notches 2A, 2B and 3A, 3B are formed at both ends of the core by a predetermined length and width. A pair of slits 4A and 4B are formed symmetrically with respect to the tube axis, with the center line of the circumferential width coincident with the center line of the pipe in the longitudinal direction. It is formed to have a predetermined length and width. The winding core 1 is made of synthetic resin, for example.

The fixture 5 has a tubular shape with an inner diameter that fits around the core 1, has a length that is almost equal to the core 2, and has an opening 6 in which a tube wall having a predetermined center angle is removed over the entire length of the tube.
In addition, the center line of the circumferential width is located on a plane that bisects the central angle of the opening 6, and the notches 2A, 2B, and 3 are formed at both ends of the tube, respectively.
Notches 7 and 8 are formed which are wider than the slits 4A and 3B and have approximately the same length, and a slit 9 which is wider than the slits 4A and 4B and approximately the same length is formed at the center in the longitudinal direction. . The fixture 5 is made of, for example, synthetic resin with high elasticity.

As shown in FIG. 2, the fixing device 5 is placed over the core 1 so that the notches and slits are aligned with each other, and the end portion 10 of the recording paper 10 is
a reaches the outer surface of the core 1 from the slit 9 of the fixture 5 through the opposing slits 4A and 4B of the core 1, and then folds back and wraps the recording paper 10 around the outside of the fixture 5 several times to close the core. 2 and fixture 5, and a winding machine rotates the assembly of core 2 and fixture 5 to wind the recording paper to a predetermined length to complete a roll-up type recording paper.

Note that the slit 9 and notch 7 of the fixture 5,
8 has a width larger than each of the slits 4A, 4B and notches 2A, 2B, 3A, 3B of the core 1, so the relative positional relationship between the core 2 and the fixture 5 is adjusted by the tension at the beginning of winding. Although misalignment may occur, this can prevent damage to the recording paper. Furthermore, the notches 7 and 8 of the fixture are provided so as to engage with the protrusion of the driver of the winding machine together with the notches 2A and 3A of the winding core 1, so that either of the fixtures 5 is prevented.

[Effect of idea]

As described in detail above, according to the present invention, the tube has an opening having a predetermined center angle over the entire length, and a notch for transmitting rotational force at both ends, and a cutout at a predetermined center in the longitudinal direction. A fixing tool having slits of the same size as each other is fitted to a winding core having a pair of notches at each end and a pair of slits symmetrical to the tube axis in the center in the longitudinal direction, and the notches and slits are matched to each other. The end of the recording paper was passed through a slit and folded back to form a bonded body, and the fixed recording paper was wrapped around the bonded body for a predetermined length to create a roll-up type recording paper. Since the recording paper is rolled up as part of the core, there is no need to forget to attach the fixing device, and when the recording paper is used up, the fixing device and the core come out combined, so the core can be It can be reused as a core for winding the recorder, and the fixing device can be used as a fixing device for the starting end of a new recording paper installed, and therefore,
This eliminates the possibility of the user losing the fixing tool.
