Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a conveyance device in a facsimile machine or the like.

[Prior art]

2. Description of the Related Art Conventionally, for example, in a facsimile machine, a paper feed section for rolled recording paper is provided with a transport roller including a pair of rollers, and the transport roller is configured to feed and transport the recording paper toward the recording section. In this case, when setting the roll recording paper, the leading edge of the paper is inserted between the transport rollers, so
It is necessary to release the pair of transport rollers from each other. However, since pressure is applied to the conveyor roller pair by a spring or the like to generate a clamping conveyance force, when releasing the separation, it is necessary to separate the pair against the pressure of the spring or the like and maintain it. It's bad and requires a lot of force.

〔the purpose〕

This invention has been made in view of the above points, and aims to provide a conveying device that can easily perform separation operation for releasing the separation and maintain it while ensuring the clamping and conveying force.

[Structure] An embodiment of this invention will be described based on the drawings. This embodiment is applied to a facsimile, and an outline of the facsimile is shown in FIG. first,
The recording paper 3 pulled out from the recording paper roll body 2 supported by the spool 1 is clamped by the conveyance roller 4, and by manual rotation of the recording paper 3, passes between the guide plates 5 and 6 and is transferred to the recording section by the thermal head 7 and the platen roller 8. reach While being recorded by a thermal head 7 in this recording section, the recording paper 3 is conveyed by a platen roller 8, cut by cutter units 9 and 10, and discharged by a paper discharge roller 11.

Here, the recording paper roll body 2 and the conveyance roller 4 are combined into a unit by a storage case 12 as shown in FIGS. 2 and 3.
can be freely pulled out from the facsimile main body. That is, the recording paper roll body 2 is rotatably dropped into the storage case 12 via the spool 1 and held therein. The conveyance roller 4 is composed of a pair of rollers, a magnetic rubber roller 4a and a metal roller 4b, and a knob 13 is provided on the shaft of the metal roller 4b. Further, the magnetic rubber roller 4a is attached to a bracket 1 which is rotatable around a fulcrum 14.
5, so that it can move toward and away from the metal roller 4b. A grip portion 16 is formed at the upper end of this bracket 15. Metal guide plates 17 and 18 are provided between the conveyance roller 4 and the guide plates 5 and 6. Metal guide plate 17
The tip end is a manual cutter 17a, and the rear end is a holding part 17b extending upward near the magnetic rubber roller 4a.

In this configuration, the recording paper 3 is
The recording paper 3 is conveyed to the recording section by the rotation of the conveying roller 4.
The sandwiching and conveying force is ensured by the magnetic force of the magnetic rubber roller 4a on one side and the metal roller 4b on the other side, so that reliable conveyance is achieved.

Therefore, when replacing the recording paper roll 2, the storage case 12 is pulled out from the facsimile main body, and a new recording paper roll 2 is set.
Then, in order to insert and set the leading end of the magnetic rubber roller 4a into the conveyance roller 4, the magnetic rubber roller 4a is released from the metal roller 4b by lifting the grip portion 16. In this separation release operation, when the magnetic rubber roller 4a starts to separate from the metal roller 4b, the magnetic force between the two rapidly decreases, so the operability is good.
The released magnetic rubber roller 4a can be easily held by suctioning and holding the holding portion 17b of the metal guide plate 17 as shown in FIG. In this state, insert the leading edge of the recording paper 3 between the magnetic rubber roller 4a and metal roller 4b, return the magnetic rubber roller 4a, and then cut the leading edge of the recording paper 3 with the manual cutter 17a to complete the insertion set. After the operation is completed, it is only necessary to attach the storage case 12.

〔effect〕

Since this device is constructed as described above, the clamping and conveying force of the conveying rollers is sufficiently secured under the magnetic force, and when the separation is released, this magnetic force is rapidly reduced, so that the release operation is easy and the released state is maintained. can also be easily held using a metal guide plate.
