It can be drained to 1llll+.

The driving side and the driven side of the mixing roller 11111 (11111) are constructed so as to be interlocked by a power transmission means such as a belt.In addition, the carriage 10 is moved along the guide shaft 1 in the backward direction of iiJ in Fig. 1. Then, reading and recording are performed in the forward movement, and when returning, the document or recording paper is conveyed and fired.The speed is also a matter of the reading accumulation time, the recording paper n + waiting time, and the contact η of the thermal loop and the recording paper. Because of this, the speed of the carriage is slow during the forward movement] and faster during the return (the speed is μ7 times the speed of the previous IIL11).

As explained above, the conventional device includes the document iS feeding roller drive in the C take-up device 6 and the reciprocating four-heave drive of the carry large 10, the small iC edge paper feed in the recording section. There is a material part for each motor in the course of the roller drive, and even if this is not the case, the conventional device 1 has at most a TC recording device 1-C and an Ir, L carriage 10.
The main scanning and conveyance of the recording paper (image setting) are performed by one motor, that is, when the carriage 10 returns, the 0' cam and the 0' slide 111 are valved, and 4 (Hot transfer)
The mechanism for printing is 1, and the facsimile-related device 6 is 0.
A single motor is used to transport the original and the recording paper.9"6
f was 9.11 and v'C did not stagnate.

1. The object of the present invention was developed in view of the fact that the complexity of each driving means in the conventional device as described above has an impact on the price of the camera. By implementing a method in which Gi is added to each drive means using only one motor, the number of component parts such as motors and electromagnetic cranks is reduced, and the number of components is increased from 1 to 11 (1 + Ili), and the motor load is reduced. It is an object of the present invention to provide a drive device for the facun milli scanning r11+s which brings about equalization and improvement of the feed shield assistance.

Embodiment 11. Recording according to the present invention is better than when reading (when transmitting). ′Jl (
By greatly reducing the moving distance of the carriage at the time of receiving (vi), the driving force for transporting the recording paper is increased by the carriage position 1fVC.
By fully engaging the release trigger, a single motor is used to perform main running and feeding of originals and recording paper without using an electromagnetic clutch or solenoid. Therefore, in addition to driving the gear ridge in a reciprocating manner, in the Carino/Kako 1 (forwarding) and recording (receiving) processes, the storage rollers Vc and J are used to drive the original and the 8C recording paper, respectively. Two sets of accumulating mechanisms are provided, and the locking device of each accumulating mechanism is released at the end of the punch, but the range of carriage movement in the recording process is greater than that in the reading process. By increasing the length, although the original feed roller 90-ra is always driven, the recording paper feed roller is VC-driven so that it is driven only during aC recording.

The present invention will now be described in accordance with the implementation sequence.

FIGS. 3(a) and 3(b) are explanatory diagrams showing the energy storage mechanism and the distance (h) of the device embodying the present invention. Since the configuration is the same as that for the recording paper feed roller VC,
The energy storage mechanism that opposes the hC recording paper feed p roller V and the W rock removal groove will be explained.

As shown in FIG. 2, the carriage 10 is driven by a single stepping motor 1 with a reversing N-hi and a variable rotation speed characteristic.
1, the drive pulley 14. The primary general feed belt 13 stretched between the driven wheelies 15 is operated by the pick-up rotation of the motor IL at L6, and the main carriage 101 (1) is guided by the guide soft as shown by the arrow E11. It moves back and forth in the scanning direction and performs the necessary reading and recording during that time.
Fig. 3 (a) (b) When the scanning unit drive device rJ and the key/ring 10 are moved forward (main scanning) by the c゛゛゛゛゛ batten book execution row.
3. The driving (demarcation blue) thread VC is connected to a means such as a spring charge.
It is so constructed that it is released at the end of the recording process, and the driving force used to convey the document or recording paper is used for conveying the document or recording paper.

Fig. 3(a) shows the main structure of the carriage 100 as seen from the horizontal and right angle direction with respect to the scanning force rotation.Although not shown in Fig. 7JZ, the front 3α carriage has two parts such as 7J\1- in Fig. 2. It was fixed on a conveyor belt stretched between pulleys,
It reciprocates in the direction of the arrow, and an L-shaped bar B is mounted 24 on the front side, and one end of the lever B protrudes outside the upper part of the carrying carriage IO at a position 11tl+, and the bent end has the following features:
When the toggle spring 25 is tensioned between the main shaft of the carrier and the lever B, the toggle spring 25 is engaged with a stopper 26 which is constantly protruding from the carrier in order to control the swinging range of the lever B.

At the left and right ends of the carriage 10 in the scanning direction (in FIG. 3(a)), stoppers 28 and 29 are provided on the main body of the device at long distances close to the scanning distance of the hollow carriage, and stoppers 28 and 29 are provided on the main body of the device to prevent the carriage from moving forward. When the stopper moves at l near the turning point of the movement, the stopper becomes L-shaped and the leg of bar B ■IS1
That is, the lever 13 is engaged between the lever 24 and the receiving part of the toggle spring 25, and the lever 13 is rotated around the support shaft [24] in the M1 direction by 6' against the elasticity of the lever spring. As a result of -f:, when the gear ridge 10 returns to the left position 1d, the L-shaped bar B rotates counterclockwise, and one end is placed outside the upper part of the carriage 10 11111. As you approach the right end position, the stone side 29V rotates clockwise,
Protrusion Q: The protrusion is close to the upper part of the gear ridge body and cannot be engaged with the side edge of lever A, which will be described later.
occupy

The locus of the protruding end of the lever B in the forward movement of the carriage 10 is shown in FIG. 3(b).As shown in FIG. It is in a position where it engages with the side edge, and as the carriage 10 moves forward, the entire 11111 edge of the lever A is suppressed from sliding, and is rotated about the lever Ai axis 30'f in the anti-training direction.

Note that the elongated lever A is locked near the υ angle of its head surface to the tension spring 31, and is biased to rotate clockwise around the shaft 30, while the rotation is restricted by the entire strike lever 32. ing.

By the way, when the carriage 1.0 moves to the right,
As mentioned above, due to the engagement of the upwardly protruding tip of the L-shaped bar B with the lever A, the lever A is rotated in the counterclockwise direction around -1130, but the lever is not in this rotated state. In order to hold the lever C, as shown in FIG. Lever C engages with the L-shaped outer edge of lever A, and lever B moves lever A counterclockwise (Fig. 3 (b).
)) Due to the rotation, it is rotated clockwise around the shaft 39, and eventually the lever A is disengaged from the outside and is brought into line with the stopper 40 by the action of the spring 330.
．． 1, and as a result, even if lever B is rotated in the force direction at time δ] and the engagement between lever B and lever is disengaged, the engagement of lever C with the upper end of lever C will cause its release. It is often held in IN.

Next, in the reading of the carriage 10 and the recording valley end process, the carriage 10 and the right side abutment 4 of the lever C are engaged,
Lever A2 is rotated in the direction of the singing force (Fig. 3 (a)) against the spring 33vC, and lever A by the upper end of <-C
Clockwise rotation (Fig. 3 (b)) Since the blocking action is released, the lever 8 is rotated in the special training direction (1st rule on the near side in Fig. 3 (a)) in Fig. 3 (b). Motion - no. At the end of the L-shaped printing bar A opposite to the shaft 30, there is a support shaft 34Q valve and a recording paper main drive roller 7? A radiant lever D is connected to the ratchet wheel 35 for full rotation (see Fig. 4), and the rotation of the lever A causes the ratchet wheel 35 to rotate one bottle at a time. By one movement of the carriage 10, the recording paper 5 is transported by the necessary width for the next recording. In addition, ratchet wheel 3
5, as shown in FIG. 4, a roller 36 for stably stopping the ratchet wheel 35 is supported by a leaking lever Ek 37, and levers D, E,! 1) The spring 38 is tensioned and installed in (1).

Furthermore, in the present invention, since the carriage movement range during recording is larger than that during reading, the lever A, which is the energy storage mechanism for driving the document feeder 90-3, is activated during reading scanning. 1 can be released, but the lever A of another energy storage mechanism for driving the recording paper feed roller 7 is locked, so the recording paper 5 is released during reading (transmission).
is never transported. In addition, since the gear ridge movement range is larger during recording (reception) than during reading, each lever A of both energy storage mechanisms is activated so that the document is transported at the same time as the recording paper is transported. However, even if the document feed roller does not rotate all the time, there is no problem because the situation that must be avoided, such as the recording paper being conveyed wastefully during reading, does not occur.

Next, we will clarify its effects.

The movement of the carriage 10 during recording is made longer than that during reading by increasing the length of the p end V, as shown in Fig. 3 (
When the carriage 10 is moved at the dashed-dotted line position l shown by the solid line in a), the lever A is on the other side of the paper, that is, as shown in FIG. 3(b).
It is lifted counterclockwise (centering on the support 30) and held in the lifted state (dotted chain line) by the lever OK.In this state, within the range of carriage movement during reading, press the recording paper lever C. The engagement between the lever A and the lever A will not be disengaged. Therefore, when the lever A is rotated, the lever D and the ratchet wheel 35 act as the recording paper J. At the end of the movement of step 10, the carriage 10 pushes the lever C of the reading unit 1 and moves the lever [11] as shown by the dashed line l) in FIG.
1139 in the clockwise direction, lever Q
+! l: Lever A (7) m When the engagement is outward, the lever AH rotates with the force of the spring 31 about 4'll + 30i in the same manner as the clock. Accordingly, the lever D connected to one end of the lever A by the support shaft 34 is pulled downward as shown in FIG. 4, causing the ratchet wheel 35 to rotate.

Since the document feed roller 3 is connected to the ratchet wheel 35, the document feed roller 3 is connected to the end of the gear ridge movement.
will be driven. Similarly, during recording, the energy storage mechanism is released f' and the recording paper feed roller 7 is driven, but in this case, the energy storage mechanism of the document feed roller 3 is also divided by 110 by lj'f. Since the recording paper feed roller 7
The feed roller 3 is also driven. Effect: In the present invention, the distance the carriage moves during recording (receiving) is longer than that during reading (transmission), and the trigger for releasing the driving force for conveying the i1e recording paper is determined by the gear ridge drop. Since it is V-shaped, it is possible to stop the recording paper drive when loading VC1♂ without using an electromagnetic clutch or solenoid, and moreover, the main scanning and feeding of the original and recording paper can be performed with a single motor.

Note that the document feed roller 2.3 and the recording paper feed rollers 6, 7
1 drive, levers A, B, C, D.

There are two sets of ratchet wheels 35, etc., and the document feed roller is driven at the end of the gear/movement section at the end of reading, so it can be used even when the carriage movement is large. However, there is no document in the document feed roller even if it is being driven at times other than sending (reading).
As explained above, according to the present invention, it is only necessary to provide the mechanical parts for one motor, so the control is also done by r1.
11 units, and since the transport driving force is accumulated during forward movement, there is also a load range, making it possible to reduce the price. In addition, when using a clutch, there is no risk of errors due to response load, slippage, etc., and the feed accuracy can be increased to 1°.
