Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a marking device for facsimiles, copying machines, etc.

BACKGROUND TECHNOLOGY Conventionally, facsimile reading devices and automatic document feeders of copying machines have been equipped with marking devices that stamp "completed" etc. on the originals in order to ensure that the originals have been sent or copied. be. However, when looking at this method, the document is stamped by temporarily stopping its feeding at the time of stamping, which wastes feeding time. Also, Heisei 11
Some stamps (simple stampers) with a J-shaped stamping surface are driven directly by an lenoid, but they make noise and the edges of the stamp are unclear, making them unsuitable for printing fine letters.Especially for facsimiles, When stamping on the reading side of a document using flat 11F type bottom-side scanning, with a stamp impregnated with ink in the flat 11F format, the ink will not come out unless it is always facing downward and facing upward only when stamping.

Machine 4'! 'I become complicated.

1 self 9 The present invention was made in view of these points.

It is an object of the present invention to provide a simple marking device i'i: capable of stamping a document without stopping the feeding of the document.

composition An embodiment of the present invention will be explained based on the drawings.

This embodiment is applied to a flat bottom scanning type facsimile machine, in which original transport rollers (3) and (4) are provided in front and behind a tag glass (2) that has a convex position on the reading section (1). ing. These document conveyance rollers (3) and (4) are driven by a motor (not shown) via a deceleration pulley, a belt, etc.
The driven rollers (5) (6) are connected to each other and are in opposing contact with the upper part.Then, an upper guide plate (7 bar 8), a lower guide plate (9) α0, etc. are provided, and the document conveying roller A document conveyance path (19) is formed between the document conveyance roller (3) and the driven roller (5). (
1) When the light is sent at time t, it is illuminated by the fluorescent light J0 and read by a reading element (not shown) via the mirror Oψ.

Therefore, the document conveying roller (3) of the document conveying roller (4)
) side, a stamp roller 05j is provided facing the feed path θυ. This stamp roller O
Q is formed of resin, metal, etc.
A stamp aη having a fan-shaped large diameter part with the same diameter as the stamp roller 4 is formed on both ends of the stamp aη, and a stamp aη having a fan-shaped large diameter part is formed at both ends thereof, and further between this 727900 and at a position f/j−. The protruding document conveyance roller (3) from the large diameter portion (47 has the same diameter as the stamp a) is formed.
A cleaning wheel (1') serving as a stamp stand member is disposed facing above the stamp roller α. This cutting wheel is supported rotatably by the platen (A) while being pressed downward, and has a length of 7 langes (αl) and is set to be long. Then, there is an insertion hole G below the stamp roller 4! Four parts C formed in a part of the mantle
An ink roller (c) which is regulated at p position M by Q and is rotatable about a shaft (c) is provided at IL. The length of this ink roller (c) is shorter than the length of the 7 langes (a'h), and the length of the ink roller (c) is shorter than the length of the 7 langes (a'h). A sensor e71 is provided near the document conveying roller (3) and driven roller (5) to detect the leading and trailing edges of the document.

Here, looking at the rotational force transmission system for the stamp roller α, the gear (
C) and gear 0 (L) fixed on the shaft are intermediate gear C3.
]), and the stamp roller 4 is set to rotate in the same direction at the same linear speed as the original conveyance roller 4. By the way, 1 in gear
)) is rotatable with respect to the shaft (c), and rotates together with the shaft (c) with the clutch mechanism 0 in a connected state. That is, a winding drum wheel 0] is fixed to one end of the shaft (c), a clutch spring O◆ is attached to its periphery, and the horn (34) of the clutch spring 0 is connected to a gear (a).
The other horn (34) is locked in the sleeve (35) of the sleeve for one-turn clutch.The outer periphery of this sleeve (34) is locked in the sleeve (35). An actuator (solenoid 1.37) is provided to switch the clutch mechanism 0 on and off. In other words, the actuator cQt is connected to the fulcrum 0→
It is rotatable around the center and is biased to lock onto the stepped part of the sleeve (p).
Due to the suction operation of the solenoid 0'i), the clutch mechanism 0' is disengaged from the stepped portion (35) and placed in the engaged state.

In such accommodations, the solenoid O'i)
is not energized and the clutch mechanism Q→ is in the disconnected state, so under the regulation of gear (c) skin (29), the stamp θ odor of the stamp roller αυ is not as shown in Fig. 4 (-1). At this time, the lower end of the director 0'Jl protrudes by 11 from the lower surface of the upper guide plate (8), and the stamp roller 0υ end is retracted by 12 from the lower guide plate (tq+ upper surface), and the distance between the two is Since a large gap is formed between the two, there is no problem in reading and conveying the original 9'4.

When the trailing edge of the original document is detected by the sensor Qθ9, the sensor Qθ9 is detected according to the distance from the preset Vθ position to the stamp position and the wire ring of the document transport roller (4) as shown in the figure. The issue from the 1111th section of the system is
Taking into consideration the start-up time of solenoid 0'7), set the stamp so that the center of the stamp is approximately 5 cylinders from the rear edge of the document.
The solenoid 07) is energized at a predetermined timing. Here, when using a step motor, the rear end detection signal from the sensor Qθ is detected by the solenoid Q7).
The energization deviation is good. In this case, +IJ! of the document transport roller (4)! There is no problem even if the speed changes.On the other hand, when feeding at a constant speed using a synchronous motor, a DC motor, etc., the detection signal of sensor Cd/7 is determined by the p counter. It is a good idea to energize the frenoid zero power without any delay.

In any case, when the solenoid (+i) is energized at a predetermined timing and the actuator OQ is rotated and disengaged from the step (3 moments), the clutch mechanism 0 becomes in the mesh state υ, the gear (c) , the stamp roller α starts rotating through the intermediate gear 0υ and the gear OQ and enters the stamping operation.During this rotation, the stamp θ line presses into contact with the ink roller ψυ as shown in the 41st ffil (At), and ink is supplied. In other words, the ink roller (c) does not constantly contact the stamp Q information, but only temporarily during the rotation of the stamp operation, and the ink roller (c) does not come into contact with the stamp Q information. The deformation in (c) is prevented.Then, as the rotation of the stamp row 200 progresses and the stamp 0 groan reaches the ritual 0 trowel position, i'l', Figure 4 (d)
While pushing the octagonal spear upwards so that the amount of bow is 44, stamp [vrJ, etc.] on the rear edge of the manuscript side of the manuscript. It will be done. At this time, since the stamp 0 is rotating at the same linear speed as the document conveying roller (4), the stamp can be stamped without stopping the document 0 in any way. Since the stamp rm only needs to have 9 resin or metal stamps, the edges of the stamp are clear and suitable for fine letters. By the way, before the stamp 0 smoke for sealing, as shown in FIG. 4(C), 7 lunges αη
The distance between the two is 71 inches, and the distance between the two is only 13 inches, and the vertical movement of the manuscript is restricted, so the sharp stamp is 11 inches north.

In this way, when the stamping is completed, the actuator is turned on again.
When Q engages with the stepped portion (3!) of the sleeve Q, clutch mechanism 1 clutch 4 becomes disconnected, and the stun roller type J
etc., the state returns to the state shown in FIG. 4 (α). .

In this embodiment, the stamp is stamped on the rear edge of the document Q, but it is also possible to detect the leading edge of the document (6) with a sensor and print the stamp on the leading edge of the document in synchronization with this. can.

Effects The present invention is constructed as described above, and the stamp roller method is used to stamp a document without completely stopping the feed of the document. It is possible to make the edges of the stamp clear and to make it suitable for small letters.
