Abstract

PURPOSE:To protect the edge of an apertured original card from damage, by making a resistance roll of a material of low frictional resistance and by moving down and stopping the resistance roll and operating a right and left resistor in the final stage of resistance action. CONSTITUTION:When the front end of a card (a) is moved to the position A of a sensor, a separating roller 2 is stopped and feed rollers 9 and a resistance roller 3 are driven and a card hold-down member 4 is opened. When the front end of the card (a) is moved to a position B, the resistance roller 3 is moved down so that the card is conveyed while being pinched between the roller and a platen 5. When the front end of the card is moved to a position C, the roller 3 is moved up and a right and left resistor 8 is operated. After that, the roller 3 is moved down and stopped and the card hold-down member 4 is closed to hold the card (a) down. Because of the first resistance action in the front-to-rear direction before the operation of the right and left resistor 8, the card (a) is stipped upstream to a stopper so that the card is protected from damage. The roller 3 is not rotated in the second half of its descent during the second resistance action in the front-to-rear direction, so that the card (a) and the roller slip relative to each other. Since the friction on the roller 3 is low, the card (a) is not damaged.

Description

[Detailed description of the invention] Regarding the strike method.

Conventionally, to set a manuscript in @completion, you have to do it manually, or Iji. In the case of a standard type with a relatively thick bucket such as an aperture card, it was automatically set on the manuscript table by making contact with the first class vc of the strut horn provided on the manuscript table, but these methods took a long time to operate. There was no definitive method because the cresest was not consistent, and the edge of the aperture card was damaged in the case of automatic installation.

The present invention is a registration control method that uses an automatic setting method and does not damage the edges of the Ano 4 Chua card.

Figure 1 shows a schematic view of the mechanism (111) until the aperture card is set on the document table, and Figure 2 shows the plan view of the card registration mechanism in the document table. This is a book that charts the following.A large number of originals are stacked on a tray L, separated by a sorting roller 2, sent seven sheets at a time to the original platen, and automatically registered. Ingchart shows only 7 pieces.

First, when stacking and setting the document tray IK document card a,
As shown in FIG. 3, after 0.5 to 7 seconds, the feeding operation of the seven cards toward the document table 5 is started. When the tip of the card reaches the @l sensor position indicated by A, it is a sleeve:
The feed roller 2 is stopped, the feed roller 9 is driven, and then the registration roller 8 is driven. The presser foot 4 is lowered so that the card can be inserted into the document table 5.

When the card passes through the feed roller 9 and is transported to a certain position (indicated by 8), the solenoid is driven and the registration roller 8 is lowered, and this roller 8 and the feed end of the document table 5 are moved. A card is sandwiched between the two and moved forward to be placed on the document table. This resist roll 8
The falling time is 0.4C seconds. Since card feeding by the registration roll 8 causes slippage, the time required for the card to be completely placed on the document table may vary somewhat depending on the card. Therefore, a third sensor V was placed at the end of the document table! i (This position is indicated by C) When this sensor detects the tip of the card and detects a fist that substantially raises the card onto the document table 5, the above 0. The registration roll 8 is made to rise up without waiting for q seconds.

Since the lowering of the registration roll 8 is relatively slow, it is important to provide an idle time for Q and / before the next operation. Q, one second later, the side register lenoid 6 is energized, and the lenoid operation of the card in the left and right direction from the side edge of the document table is performed. After 0.2 seconds, the registration roll 8 is lowered again while the registration operation in the left and right direction is being performed, and the front and rear registration is again performed for 0 seconds. Next, the driving of the registration roller 8 is stopped, and the power is turned off to the card presser release solenoid 7, and the card presser 4 is closed to press the card so that it does not move. Taking into account the time delay between the stop of the reno roller and the activation of the card holder, after 0.2 seconds, the power to the side registration lens nod 8 and the solenoid for lowering the registration roller are stopped, and the document platen of the card is stopped. The resist action is completed.

A feature of the method of the present invention is that the front and rear registrations of the previous card are performed in separate steps.

To put it in a positive light, the 7th card feed to the manuscript table 5 7Δ
When driving, stop at a position 2III or more away from the mother. If you use the conventional resist method to make this stone SVC@*, the edge of the card will often be damaged, and the edge of the card should not come into contact with the strut horn 9, leaving enough room to avoid friction during the next left and right resist operation. This is to prevent damage to the edges caused by this and to make it easier for the card to move left and right. In the second back and forth registration operation, the amount of advance is approximately gO.
■ is set. In the second half of the second registration roller descent, the registration roller 8 does not rotate and the card and the registration roller 8 slip, and the left and right registration operations are performed. This means that the edge of the card will never come into contact with a stone or stone, there will be no damage to the edge of the card, and there is no risk that the card will become free and shift due to mechanical vibration or the like. Therefore, the material of the resist roll 8 has a friction coefficient of 0. /-0
, 't utilizes urethane.
