Abstract

PURPOSE:To stabilize the travelling of cards being conveyed by arranging a plurality of pairs of rollers such that the respective card conveying surfaces of said rollers are displaced from each other to flatten out the cards. CONSTITUTION:A prefeed roll 4 for sequentially feeding out set apertured cards C, a separate roll 5, an idler 7 and a plurality of pairs of upper and lower feed rolls 8 for sending the card C onto a manuscript base 10 along a chute 9 are provided. Also, the feed roll 8 located in the middle is disposed such that the card conveying surface of the roll 8 is displaced to the other rolls 8. The lower side of the card C passing through these rolls 8 displaced thus relative to each other is corrected with respect to bends so that the passed card C can be conveyed with stable flat condition onto the manuscript base 10.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention primarily relates to an aperture card conveying device in a microcopying machine.

Conventionally used copying machines have been constructed without paying special consideration to the characteristics (particularly moisture content) of the cards used.

Therefore, when a large number of cards are set on the copy machine's camera tray, the cards mentioned above may undergo significant environmental changes (during card production, during storage, etc.) due to the temperature inside the machine, the way the air flows inside the machine, etc. (Due to the difference between the environment and the environment inside the copier), cards that are exposed to
, the card was prone to malfunctioning and damage.

The present invention has been made to address this problem, and its object is to provide a card transport device that stabilizes the running of a transport card within a copying machine.

That is, in the present invention, in the card conveying device of a copying machine, each card conveying surface of a plurality of pairs of conveying rolls is arranged to be displaced from each other, so that the shape of the card being conveyed is corrected. With the above configuration, the warped card is bent in the opposite direction and flattened during travel, and stable card transfer is performed.

Hereinafter, the present invention will be explained based on an embodiment shown in the drawings.

The aperture card conveying device in a microcopying machine includes a card set tray section 1 consisting of an approach plate 3 and a set tray 2 on which a large number of aperture cards and cards are placed, and a card set tray section 1 disposed on the approach plate 3. A pre-feed roll 4 that sequentially feeds out the aperture cards C one by one, a separate roll 5, an idler 7 disposed in contact with the roll 4.5, and an idler 7 disposed opposite to the roll 5. The feed roll 8 is composed of a friction roll 6 and a plurality of pairs of upper and lower feed rolls 8 that feed the aperture card 0 onto the document table 10 along the shoe A9.

Further, among the feed rolls 8, the feed roll 8 located at the center is arranged so that the card transfer surface (the contact surface of the upper and lower rolls) is displaced with respect to the other feed rolls 8.

Thus, the aperture card 0 set on the approach plate 3 warps upward under the influence of the temperature and air flow of the copying machine.

However, since the aperture card C is pressed by the pre-feed roll 4, there will be no conveyance failure at the separate roll 5 portion, and the aperture card C is sequentially transferred from the topmost aperture card 0 to the feed roll 8, and is mutually displaced. By passing through the plurality of pairs of feed rolls 8 arranged, the aperture card C is bent downward and straightened, and after passing, the aperture card C is stably transferred and placed on the document table IO in a flat state.

Note that even if the analog card C set in the copying machine is already warped and deformed, the function of the transport device is activated, so the operator must There is no need to correct the warpage of the analogue card.

Furthermore, in the above embodiment, if the feed roll group is a heat roll, the water content of the curd is removed and the straightening effect is improved. A similar effect can be obtained by attaching a heater to the chute 9 section.
