Abstract

PURPOSE:To miniaturize a recorder of facsimile, etc. by connecting a paper feed motor to an automatic cutter via a unidirectional clutch. CONSTITUTION:A paper feed motor 11 is connected to an automatic cutter 12 via a unidirectional clutch 28, and at the same time a control means 32 is connected to the motor 11. The motor 11 is revolved forward to shift the recording paper 2 forward by an extent corresponding to the distance between a recording part and the cutter 12 as well as the moving time required from the waiting position of a rotary blade 15 through the cutting position. Then the motor 11 is revolved backward to actuate the blade 15 with connection of the clutch 28. At the same time, the front edge part of the paper 2 which is cut by the blade 15 is sent backward to a place near the recording part.

Description

[Detailed description of the invention] Technical field The present invention relates to a recording device such as a facsimile.

BACKGROUND ART Conventional recording devices such as facsimile machines are equipped with a dedicated motor to operate the cutter, which has drawbacks such as higher costs, increased assembly man-hours, and larger devices. be.

SUMMARY OF THE INVENTION The present invention includes: a platen roller that presses continuous recording paper against a recording section of a recording head; a paper feed motor that drives the platen roller to transport the continuous recording paper; In a recording device such as a facsimile machine, which has a rotary automatic cutter that cuts at both the flow side and the
A paper feed motor and a self-help cutter are connected via a one-way clutch, and a control means is connected to the paper feed motor,
After recording is completed, the paper feeding motor is rotated in the forward direction to forward the recording paper by a distance corresponding to the distance between the recording section and the automatic cutter and the travel time of the rotary blade from the standby position to the cutting position. Reversing the paper feed motor and connecting the one-way abrasion clutch to cause the rotary blade to cut the rotary blade, and to feed the front 14 pieces of recording paper cut by the rotary blade back to the vicinity of the recording section. Accordingly, the paper feed motor is also used as a drive source for the self-contained cutter, and a dedicated drive source for the automatic cutter is omitted. Furthermore, by utilizing the fact that the paper feed motor switches to the reverse direction when the recording paper is fed backwards to engage and release the one-way clutch, the automatic cutter can be easily operated without using an expensive electromagnetic clutch or the like. It can connect and disconnect power.

The recording paper motor rotates forward and reverse at appropriate timing.

Next, the configuration of the =S notation means g34 is taxed together with the operation of the device.

- In the standby state, in the above apparatus, the front end of the continuous recording paper (2) is located near the recording section (6a), as shown in FIG.

In the standby state, the control means (3rd step starts 1d start signal (Sl)
) In the above device, the drive signal fij (S 2 ) is output from both sub-means, and the continuous recording paper (2) is recorded with an image in the recording section (6a) and is fed forward. Part (6a)

During normal feeding in 2), since the one-way clutch +2111 is disconnected, the self-help cutter H does not operate, and its rotary blade (I5) does not move from the standby position 1.

When the forward feeding of the recording paper (2) ends and reaches the downhill position shown in FIG. However, the recording paper (2) is fed backward, and the one-way clutch (c) becomes a connecting path, and the L!1 rolling blade αb) is turned to the turn end via this clutch 028+. Recording paper (2) is written on the edge of page 2 (2a or the above-mentioned Komisoftai pIi section) and is said to have been taken by people.
The turning blade (I5) is in cutting position i! It reaches c- and is cut.

The recording paper (2) that was cut at Jino at Miyako was sent back to Jo,
At the same time, the rotating blade 05) was also rotated clockwise, and finally, the recording paper (2) was moved by the distance (a) and the rotary blade returned to the standby position. In the state shown in FIG. 3, the motor body is turned on (S2) and the reverse rotation signal (S3) is stopped.

In addition, in the device M, when the grating roller (lO) is rotating in the normal direction, the one-way clutch V is disconnected and the rotary blade (15) in a free state is moved to the standby position (from the barrel to the lO). There is a risk of misalignment, but for ξ misalignment, the click member operated by a cam etc. is replaced with a rotary blade
It is good to be associated with.

And ψJ Me, In the table, the first detection means (9)
K detects whether or not the recorder's roll paper (2) is set, and the second detector 19 (19) detects whether or not the recorder's roll paper (2) is set.
The system detects abnormalities such as when the paper is fed backwards too much and the next forward feed is not possible, or when the recording paper (2) jams due to the self-cutter a smell, and takes control of the erasure control. Then, the device is stopped and a different hanging display section (not shown) is energized.

Possibility of use on local chestnuts The present invention can be used in a distribution device such as a facsimile equipped with a mackerel J cutter.
