Abstract

PURPOSE:To attain miniaturization of the titled recorder by using a drive motor so as to drive selectively a platen roller and a cutter. CONSTITUTION:One pulse motor 26 is used as a power source for the platen roller 23 and the cutter 24 and a clutch member 30a to drive the both selectively is provided. The clutch member is docked to a gear 34 through unexcitation of a solenoid except the period operating the cutter 24 and a torque of a pulse motor 26 is delivered to the platen roller 23. When the recording is finished and a recording paper sheet 21a is placed to the cutter 24, a control circuit energizes the solenoid. Thus, a clutch member 30a is docked to a disc upper link 35, resulting that the torque of the motor 26 is switched from the platen roller 23 to the cutter driver.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a recording device equipped with a platen roller that conveys recording paper and a cutter that cuts the recording paper conveyed by the platen roller. relates to an improvement of a drive mechanism for driving a platen row 2 and a cutter.

[Technical background of the invention]

Facsimile recording devices generally employ rolled recording paper as the recording paper. In such a recording device, when a portion of the received information is recorded, the recorded portion is cut by a cutter and discharged to a stacker.

FIG. 5 shows such a conventional recording device. In this recording apparatus, a recording paper roll 1, a thermal tray 2, a platen roller 3, a cutter 4, and a tray 5 are arranged in this order, and the recording paper 1a fed out from the recording paper roll 1 is transferred to the platen roller 3, the recorded portion is cut by a cutter 4, separated from the recording paper roll 1, and stored in a stacker 5. In this recording apparatus, /IP pulse motors 6 and 102>f are used as power sources for the platen roller 3 and cutter 4, respectively. The power of the pulse motor 6 is provided by a pulley 7 fixed to the shaft 6a of the mother lune motor, a pulley 8 fixed to the shaft 3a of the platen row 23, and a belt 9 wound between these gooliffs and 8. The power of the pulse motor 10 is transmitted to the platen row 23 by the power transmission mechanism, and the power of the pulse motor 10 is transmitted to the link 11 fixed to the shaft 10aK of the 74' pulse motor, the link 12 fixed to the swinging blade (not shown) of the cutter 4, and these links. The force is transmitted to the oscillating blade 4 by a power transmission mechanism consisting of a link 13 engaged with 11.12.

[Problems with background technology]

By the way, in the conventional recording apparatus, since the drive timing of the platen roller 3 and the swinging blade of the cutter 4 are different,
As mentioned above, two pulse motors 6.10 were used to drive them.

However, arranging a respective drive motor for each driven element in this way reduces the cost of the device;
This was also a factor that hindered miniaturization and weight reduction.

[Purpose of the invention]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a recording device that can reduce the cost, size, and weight of the device.

In this recording apparatus, a single 79 mm motor 26 is used as a power source for the platen roller 23 and cutter 24, and a gear 27 is fixed to its shaft 26m. In addition, in this recording device, a shaft 29 is installed in the frame 28 in parallel with the shaft 26m of the drive motor 26, and on this shaft 29, a club and a chimenpa 30 are rotatable and slidable in the axial direction. It is located in This clutch member 30 has a gear 30a formed on its side, an annular 1% 30b, and a dog 30c on its side.
, 30d are formed. And clutch member 3
The gear 30a of 0 is meshed with the gear 27, and the annular groove 30a is meshed with the gear 27.
One end of an arm 32 operated by a solenoid 31 is fitted into b.

This solenoid 31 is in a de-energized state, and the sugering 33
The arm 32 is held in the position shown in FIG. 2 by the biasing force, and when excited, the arm 32 is moved to the right in FIG.

Further, on the shaft 29, a gear 34 forming an end element of a power transmission mechanism for the platen roller and a disc-shaped link 35 forming an end element of a power transmission mechanism for a cutter are attached to a clutch member 30.
It is arranged so that it is sandwiched between the two. The gear 34 and the link 35 are loosely fitted to the shaft 29 so as not to be movable in the axial direction. Also, gear 34 and link 3

The operation of the recording apparatus will be explained below.

In this recording apparatus, the solenoid 26 is in a non-energized state except during the period when the force and the output 24 are operated, so that the solenoid 26 is dog-coupled to the gear 34 as shown in FIG.

Now, when a recording start signal is input to the control circuit (not shown) of the recording device, the pulse motor 26 is activated based on the signal.
rotates in the forward direction (arrow A direction). The rotational force of this /4′ motor 26 is transmitted through the gear 27, clutch member 30,
The signal is transmitted to the platen row 223 via the gears 34 and 36, and rotates the platen row 223 in the forward direction (direction of arrow B).

Therefore, the recording paper 21 fed out from the recording paper roll z1
a is conveyed in the forward direction (in the direction of arrow C) by the platen row 223. Further, a recording signal is inputted to the control circuit (not shown), and based on the signal, the thermal head 2 is
2 is driven. Therefore, the recorded images are sequentially recorded on the recording paper 21a. When a portion of the recording is completed, an end signal is input to a control circuit (not shown), and the pulse motor 26 is further rotated by a predetermined amount, and the recording paper 21a is
The cutter 24 is stopped when the cutter 24 is positioned at the location to be cut. When the recording paper 21m is positioned on the cutter 24, the solenoid r931 is energized by the control circuit.
Accordingly, the clutch member 30 is moved from the state shown in FIG. 2 to the state shown in FIG. It is separated from the plate-like link 35. Next, the ankle motor 26 is rotated in the forward direction (direction of arrow A). Therefore, pulse motor 2
The rotational force of 6 is transmitted through the gear 27, the clutch member 30, the disc-shaped link 35, the link 38, and the link 37.
The signal is transmitted to the swinging blade (not shown) of No. 4, and drives the swinging blade. As a result, the recording paper 21m is cut. The recording paper 21b cut in this way is discharged onto the tray 25.

When the swinging blade (not shown) of the cutter 24 reaches the standby position again, the control circuit (not shown) activates the tq rusmo.
126u is stopped, and then the solenoid 31 is demagnetized. Therefore, the clutch member 30
3 returns to the state shown in FIG. 2, and the brake arm 39 again comes into contact with the surface of the disc-shaped link 35. Next, the control circuit (not shown)
The pulse motor 26 is reversed. Therefore, the rotational force of this Girnu motor 26 is
the platen row 22 via the gear 30, gear 34, and gear 36.
3 is reversed, and the recording paper 21& is conveyed in the opposite direction (the direction opposite to arrow C). Then, the platen roller 23 is stopped just before the leading edge of the recording paper 21m reaches the thermal head 22.

With this recording device, by repeating the above operations,
The next page and subsequent pages are recorded.

In the above embodiment, the power of the pulse motor 26 is directly transmitted to the crane and chimenpa 3o, but in the present invention,
The present invention is not limited to such a mechanism, and for example, the mechanism of the other embodiment shown in FIG. 4 may also be employed.

In the embodiment shown in FIG. 4, a shaft 29 is rotatably disposed on the frame 28, a gear 40 is fixed to the shaft 29, the gear 40 is meshed with the gear 27 of the pulse motor 26, and the clutch Member 30 is splined to shaft 29.

Therefore, in this embodiment, the power of the pulse motor 26 is transmitted to the clutch member 30 via the gear 27, the gear 40, and the shaft 29.

Furthermore, in the present invention, the rotating shaft 29 shown in FIG.

In this way, the shaft 29 is rotated directly by the pulse motor 26, so that no gears 27,40 are required.

〔Effect of the invention〕

As described above, in the recording apparatus according to the present invention, the platen roller, force, and force drive, which conventionally required two motors, can be performed with one motor, thereby reducing the price of the recording apparatus and making it more compact.
