Description

DETAILED DESCRIPTION OF THE INVENTION The present invention can be used in combination with a conventional electrophotographic copying machine,
The present invention relates to a document feeding device for copying, for rapidly copying a large number of handprints, etc.

Although there has traditionally been a strong demand for obtaining copies of manuscripts such as bills drawn at banks, etc. from various administrative aspects, there is no copying machine or manuscript feeding device suitable for solving this demand. It has not been realized yet.

For this reason, the current situation is that the large number of bills that are issued each day are manually placed one by one on the document table of an electrophotographic copying machine to make copies.

As a result, it was extremely inefficient and became a tedious job for several female bank employees. SUMMARY OF THE INVENTION It is an object of the present invention to improve the current state of the art as described above, to save labor, and to provide a document feeding device for copying bills, etc., which can copy a large amount of bills, etc. with high efficiency.

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a plan view of an embodiment of an apparatus for dispensing documents such as bills according to the present invention, and FIG. 2 is a sectional view thereof.

The document feeding device of the present invention is used in combination with a normal copying machine, and when the copying machine is switched to continuous copying mode,
Place documents such as bills one by one on the document table of the electrophotocopying machine.
Copying is performed by feeding sheets one by one.

As shown in the drawings, the document feeding device of this embodiment can be roughly divided into a feeding tray 7, a copying section 8 which is continuously fixed to the downstream side of the feeding tray 7, and a copying section 8 located downstream of the copying section 8. , and a discharge tray 9 detachably attached thereto.

The document feeding device of the present invention can be used as an accessory device for a normal electrophotographic copying machine equipped with a copy start signal generating device and a copy completion signal generating device.

The feeding tray 7 includes a storage chamber 11 in which a plurality of bills, etc. 10 are stacked and accommodated, and an opening 12 is formed in the bottom surface of the storage chamber 11, and a first roller 13 for feeding out faces the opening 12.

This first roller 13 is driven by a first drive motor 15 via a transmission member 14 such as a belt or chain, and a clutch 17.

The first motor 15 is a reversible rotary motor, and is started to be driven in response to a copy completion signal, for example, when a copy completion signal is generated in synchronization with the copy cycle of the electrophotographic copying machine described above.
The first roller 13 is rotated counterclockwise in FIG. By rotating the first roller 13 in the counterclockwise direction,
One of the documents 10, such as a handprint, located at the lowest position in the storage chamber 11 is bent downward.

And, due to the curved part, the reversing micro switch 16
is operated, causing the first motor 15 to rotate in the reverse direction. As a result, the first roller 13 is also rotated clockwise in FIG. , and is sent to the copying section 8 by passing under the front shelf 11a.

In the copying section 8, as described above, the first roller 13
One sheet of original 10 sent by the controller operates the first microswitch 21.

When the first micro switch 21 is actuated by the document 10, the clutch 17 is disconnected, the first roller 13 is free to rotate, and the first motor 15 is stopped from being driven. start.

A second roller 22 located close to the first microswitch 21 is driven by the second motor 23.

As a result, the document 10 is further sent to the right (downstream side) in the copying unit 8 in FIGS. 1 and 2 by the second roller 22. When the rear end of the document 10 passes through and ends, the pressure on the first microswitch 21 by the document 10 is released.

The signal generated at this time stops the driving of the second motor 23, and transmits the copy start signal to the electrophotographic copying machine to start the copying operation. In addition, at this time, the second
The document 10 sent by the roller 22 is moved to the third roller 25 which is in a stopped state so that the document 10 is exactly positioned at a predetermined location of the exposure window 24 provided in the document placement section on the electrophotographic copying machine.
It is stopped and positioned by

In this state, the original 10 is copied by a well-known method.

The copy completion signal of the electrophotographic copying machine is sent to the third roller 25.
The signal is transmitted to the third motor 26, which drives the motor, and starts the motor. As the third roller 25 rotates, the document is sent further to the right in FIG.
Continue driving the motor 26.

On the other hand, the fourth motor 29 that drives the fourth roller 27, which is disposed on the right side (downstream side) of the third roller 25 and is driven at a higher speed than the third roller 25, is also activated by the copy completion signal. Ru. One drive of the fourth roller 27 is also continued by the operation of the second micro switch 30. The trailing edge of the document 10, which is sandwiched between the fourth roller 27 and the driven roller 28 that is pressed against it and moves to the right, passes the second microswitch 30 and releases its pressure. Then, the driving of the third motor 26 is stopped.

However, the driving of the fourth motor 29 is not stopped immediately, but is continued for a short time by an appropriate delay circuit (not shown).

As a result, the fourth roller 27 and the driven roller 28
The rotation continues, and the document 10 is sent to a discharge tray 9 which is removably attached to the copying section 8. As a result, the copied originals 10 are stored in the ejection tray 9 in a pile. After that, the first motor 15 and the first roller 13
The same operation is repeated by the rotation of the .

In this manner, when the final document 10 is fed from the delivery tray 7, the stop microswitch 18 is activated.

Therefore, when the second microswitch 30 is released from being pressed, the main switch (not shown) or a switch connected in series thereto is automatically opened to stop the operation of the entire device. The micro switch 19 is used to automatically stop the apparatus when a paper jam occurs in the document 10 during continuous feeding.

Since the present invention has the above-mentioned configuration, the exposure window of the copying document feeder in which a large number of manuscripts such as handprints are accumulated and housed in the storage chamber is placed on the document mounting table of the electrophotographic copying machine, and the electronic When the photocopier's selector switch is set to the continuous copying side and the main switch is closed, the documents stacked in the storage chamber are automatically sent one by one from the bottom to the copying section. is stopped at a predetermined position above the exposure window, and copied by an electrophotographic copying machine.

When one sheet of copying is completed, the original is sent to the ejection tray, and the next original is sent from the storage chamber to the exposure window in sequence.

By repeating these operations, all manuscripts such as handprints are automatically copied, and the operator does not have to do anything during this time, which contributes to labor savings.

Note that by placing a plurality of copying document feeding devices according to the present invention in parallel on the document table of an electrophotographic copying machine, multiple documents such as handprints can be copied simultaneously, making the work more efficient. It can also be taken as a thing.
