JPS5840173B2 - Aperture card ejection device in enlarger printer or reader printer - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an aperture card ejecting device for an enlarge printer or a reader printer.

Aperture card ejection, in which the aperture cards holding the film are sequentially ejected to a stacker after microfilm scanning is completed in an enlarger printer that enlarges and prints microfilm images or a reader printer equipped with a reading device. The device is well known.

A conventional ejecting device of this type has a pair of ejecting rollers that can come into contact with each other or be separated from each other, and the aperture card that has been scanned is held between the rotating ejecting rollers and sent to a stacker.

However, this device requires a complicated conveyance mechanism to convey the card from the discharge roller to the stacker, which has the disadvantage of complicating the structure of the entire discharge device.

The present invention aims to eliminate the above-mentioned drawbacks and to provide an aperture card ejecting device that can be particularly advantageously attached to a printer of a type that scans an aperture card in its short side direction. An example will be described according to the drawings.

In FIG. 1, the aperture card 1 is transferred from a card feeding hopper (not shown) in the long side direction of the card, that is, in the first direction.
The sheets are fed one by one in a direction perpendicular to the plane of the drawing and are stopped between two pressure plates 2 and 2' that constitute the scanning device.

These pressure plates 2, 2' are pivoted to each other at their lower parts, and when the card 1 is located between them, the two pressure plates 2, 2'
are pressed together and clamp the card 1.

Next, the card 1 is held between the pressure plates 2, 2' roller 9 and the pressure roller 18, and the card 1 is continuously conveyed upward between the belt 6 and the guide plate 19.
The card is further fed between the cards and is finally discharged into the card stacker 4.

The cards stored in the stacker 4 are in the same order and front and back as they were when loaded into the hopper.

When the card 1 begins to be held between the guide roller 9 and the fixed roller 18, the pressure plate 2.2' simultaneously descends downward.

At this time, press the pressure plate 2 so that the next card can enter between the pressure plates.
is an open S.

In the above embodiment, the guide roller 9 is made swingable relative to the roller 18, but it is also possible to fix the guide roller 9 and make the roller 18 contactable with and separated from the guide roller 9.

Further, the stacker 4 is not limited to the illustrated position, but may be placed, for example, on the left side in FIG. ) can also be configured to be discharged.

As described above, according to the present invention, the belt is wound around the guide roller, and this belt is connected to the pair of rollers 9 and 18.
It serves to transport cards from the stacker to the stacker.
It is possible to reduce the manufacturing cost of the device without requiring a complicated card transport mechanism as in the past.

Further, although the apparatus according to the present invention can be conveniently applied to a printer that scans a card in the direction of its short side, it is also applicable to a printer that scans a card in the direction of its long side.

The present invention can also be applied to a reader printer in the same manner as the above embodiments.

Claims (1)

[Claims] 1 In the aperture card ejecting device of an enlarger printer or reader printer, where the aperture card is held and moved by the same pressure plate of the scanning device during exposure and the peripheral pressure plate opens after exposure and ejects the aperture card, at least one ejecting belt placed over a guide roller located at () and another guide roller, means for driving the belt, and disposed at a position facing the guide roller located near the card ejecting side. The guide roller and the card pressure contact roller located on the card ejection side are separated from each other when the aperture card is exposed, and the card is disposed between them when the aperture card is ejected. The aperture card ejection device is characterized in that it is accessible to the user.
