Abstract

PURPOSE:To make possible the continuation of a discharge action at the time of cutter operation by allowing the first idler gear to be engaged with a discharge roller gear when a gear support rotates in a normal direction and the second idler gear to be engaged with an auxiliary gear when the gear support rotates to an opposite direction. CONSTITUTION:During normal recording, a motor rotates in a normal direction, and when specified recording is terminated and recording paper is cut, the motor 10 is reversed. Consequently, a platen roller 3 is stopped by a one-way clutch 15, but an intermediate gear 20 rotates to a reverse direction as shown by an arrow direction D. Then a rotary cutter 5 is actuated to cut the recording paper. Simultaneously, torque is given to a gear support 22 in accordance with the rotation of the intermediate gear 20 and the gear support 22 moves. The first idler gear 23 and a discharge roller gear 27 are disengaged and the second idler gear 24 is engaged with an auxiliary gear 28. Consequently, an ejection roller 6 is driven by the intermediate gear 20 through the second idler 24 and the auxiliary gear 28 to rotate in a normal direction as shown by an arrow E. In turn, the recording paper is discharged along with the action of the rotary cutter.

[Detailed Description of the Invention] Industrial Application The present invention relates to a printer using roll paper as recording paper;
0 Related to a cutter for cutting paper and a cutter and ejection roller drive device for driving a paper ejection roller in facsimile, etc. Conventionally, as shown in FIG. 4, as a facsimile machine using roll paper, Recording paper 2 pulled out from roll paper 1,
A known configuration is such that the paper is conveyed while being pressed against a thermal head 4 by a platen roller 3, recorded by the thermal head 4, then cut by a rotary cutter 5, and discharged by a discharge roller 6. In this device, a platen roller 3, a rotary cutter 5, a discharge roller 6
In order to reduce costs, a single motor that can rotate in forward and reverse directions is used to drive the platen row 23 and discharge roller 6, which are operated by a one-way clutch that transmits the rotation of the motor in only one direction. coupled to the motor;
The rotary cutter 5 is connected to the motor via a one-way clutch that only transmits rotation in the opposite direction. Therefore, when the motor rotates in one direction, the rotation is transmitted only to the platen roller 3 and discharge roller 6, and the recording paper 2 is conveyed and discharged. When the motor is rotated in the reverse direction, the rotation is transmitted only to the platen roller 3 and discharge roller 6. 26 was stopped, and only the rotary cutter 5 was rotating to cut the recording paper 2. In the following description, regarding the motor and each roller, the rotation in the recording paper feeding direction is assumed to be normal rotation.

Problems to be Solved by the Invention However, with this configuration, when the motor is reversed to cut the recording paper, the ejection roller is stopped;
During this time, the recording paper is not ejected, and after the paper is cut, the motor is rotated in the normal direction to eject the recording paper, which poses a problem in that it takes time to eject the paper.

To solve this problem, the ejection roller can be configured to continue rotating in the normal direction even when the cutter cuts the recording paper, and for this purpose, the cutter drive motor can be provided separately from the ejection roller drive motor. However, increasing the number of motors used increases costs, so it is not a good idea.

Operation According to the above-described structure, when the motor rotates in the forward direction, the intermediate gear is also driven by the motor and rotates in the forward direction, and this rotation causes the gear holder to rotate in the same direction, thereby causing the first idler gear to rotate. The discharging roller gear meshes with the discharging roller gear, and the discharging roller gear is rotationally driven in the same direction as the rotational direction of the intermediate gear, that is, in the forward direction, via the first idler gear. On the other hand, when the motor rotates in the opposite direction and the intermediate gear rotates in the opposite direction, the rotation causes the gear holder to rotate and the second idler gear to mesh with the auxiliary gear. It is rotationally driven in a direction opposite to the rotational direction of the intermediate gear, that is, in a forward direction, via an auxiliary gear. Thus, the ejection roller connected to the ejection roller gear is rotated in the forward direction and ejects the recording paper, regardless of whether the motor rotates in the forward or reverse direction. On the other hand, the rotary cutter is rotationally driven via the one-way rotation transmission means only when the motor is reversed. Therefore, even when the rotary cutter is operated by rotating the motor in the reverse direction, the ejection roller continues to rotate in the forward direction, making it possible to eject the recording paper while cutting it.
