DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Preferred Embodiment

Please refer to FIG. 1, which shows an automatic machine 10 according to a preferred embodiment of the invention. The automatic machine 10 has a sheet entrance 101 and a coin inlet 102. Examples of such an automatic machine 10 include automatic vending machines, monetary trading machine such as ATM and bill exchangers. The sheets received at the sheet entrance 101 include flat sheets such as bills, tickets, and various kinds of valued certificates.

With reference to FIG. 2, sheets 202 such as bills enter via a sheet inserting mechanism 204, such as an inlet and the connected transmitting track, into the automatic machine 10. The sheets 204 are then examined by a checking mechanism 206 to determine whether they are of a predetermined type of sheets, e.g. checking their face values or whether they are fake. The checking is done by employing such techniques as magnetic ink, hidden magnetic stripes, or optical recognition. Finally, the qualified certain type of sheets are moved from the sheet feeding track to a storing mechanism 208. The above-mentioned action is controlled by a controller 210, which provides control commands to a stepping motor for driving the sheet feeding track or to a program for executing optical recognition.

The storing module 208 in FIG. 2 is further explained with reference to FIG. 3. In the drawing, the storing module 30 contains a pushing block 302 and a sheet cartridge 304. The pushing block 302 has a pushing device 3020, an axle 3025, a base 3024, and several protruding blocks 3026. In addition, the pushing device 3020 has a stepping motor and a control circuit. The control circuit receives a control signal from the automatic machine to control the stepping motor, thereby driving the axle 3025, the base 3024, and the protruding blocks 3026 for moving in the direction of feeding sheets 3028.

Moreover, the sheet cartridge 304 has a first housing 3042, a separator comprised of at least one stop block 3044, and a second housing 3046. The first housing 3042 has a sheet feeding part and an accepting part corresponding to the protruding blocks 3026. The sheet feeding part has a sheet entrance 3043. The accepting part has patterned openings 3041 corresponding to the protruding blocks 3026.

The sheet cartridge 304 is applicable in the automatic machine 10 shown in FIG. 1. Normally, the sheet cartridge 304 is installed inside the automatic machine. In this case, the sheet entrance 3043 faces the sheet feeding track of the automatic device to receive sheets, and the patterned openings 3041 face and correspond to the protruding blocks 3026. When the sheets are loaded full, an operator takes the sheet cartridge 304 off the automatic machine 10 and brings it back to the company to retrieve the sheets stored therein.

A three-dimensional view of the sheet cartridge 304 is shown in FIG. 4, where the numerals refer to the same matters as in FIG. 3. By comparing FIG. 4 with FIG. 3, one can clearly understand the structure of the sheet cartridge 304. To avoid the operator to touch the sheets stored in the sheet cartridge 304, a lock can be installed on the sheet cartridge 304.

With reference to FIGS. 5(a) and 5(b), which show cross-sectional views of FIG. 4 in two different states, with the numerals referring to the same matters in FIG. 5. FIG. 5(a) shows the normal use state of the sheet cartridge 304. From the drawing, one sees that the first housing 3042 and one surface of the stop block 3044 form a temporary space 30421. The second housing 3046 and the other surface of the stop block 3044 form a storage space 30461. The sheets 3047 are normally stored in the storage space 30461.

For the convenience of collecting sheets, an elastic device 30462 is connected between the second housing 3046 and a stop board 30463, the structure of which presses the sheets 3047 between the stop block 3044 and the stop board 30463.

With reference to FIG. 5(b), to protect the sheets stored in the sheet cartridge 304, a lock device 305 is often installed on the sheet cartridge 304. Once the sheet cartridge 304 is brought back to the company and unlocked, it is in the opened state shown in the drawing. In this case, the manager can readily take out neatly collected sheets 3047.

The cooperation between the pushing block 302 and the sheet cartridge 304 is shown in FIGS. 6(a) to 6(c) and FIG. 7. FIGS. 6(a) to 6(c) illustrate three states of interactions between the sheet cartridge 304 and the pushing block 302. FIG. 7 is a schematic flowchart of the process. The same numerals refer to the same or similar structures as in the previous figures and are not described again.

In FIG. 6(a), a sheet 30471 is moved from the sheet entrance of the sheet cartridge 304 to the temporary space 3041 via the sheet feeding track of the automatic machine (step 702). In FIG. 6(b), the protruding blocks 3026 of the pushing block move in the direction of feeding sheets 3028 according to the control command sent out by the controller 210. Since the sheet cartridge 304 has the patterned openings 3041 corresponding to the protruding blocks 3026, the protruding blocks 3026 go through the patterned openings 3041 into the temporary space 3041 as they proceed, pushing the sheets 30471 stored in the temporary space 3041 past the stop block 34 into the storage space 30461 (step 704). At this moment, the sheets 3047 originally between the stop board 30463 and the stop block 3044 are pushed further back.

Afterwards, the protruding blocks 3026 of the pushing block return to their original positions according to a control command. The elastic device 30462 presses against the stop board 30463, pushing the sheets 30471 and other sheets 3047 in the direction opposite to feeding. In this way, the sheets 30471 are smoothly moved from the temporary space 30421 to the storage space 30461 (step 706).

In the following, we use FIGS. 8(a) to 8(c) to describe the structure of the stop block 3044. The same numerals refer to the same or similar structures as in the previous figures and are not described again.

With reference to FIG. 8(a), the stop block 3044 is between the temporary space 30421 and the storage space 30461. After the sheets 30471 enter the temporary space 30421, the protruding blocks 3026 push the sheets 30471 in the sheet feeding direction 3028 to the storage space 30461. The action of the stop block 3044 can be clearly seen in the drawing.

Please refer to FIGS. 8(b) and 8(c), which describe the shape of the stop block from another perspective and the relation between the stop block 3026 and the sheets 30471. In FIG. 8(b), the stop block 3044 is made of two separate plates. In FIG. 8(c), the stop block 3044 is made of three separate plates. In other words, the primary purpose of the stop block 3044 is to let the sheets 30471 stay in the temporary space 30421 or the storage space 30461 when they are not pushed by the protruding blocks 3026. That is, any stop block 3044 in a combination of any shape and any number belongs to the scope of the invention.

Please refer to FIGS. 9(a) and 9(b). Aside from many different variations of the stop block 3044, the patterned openings 3041 may have many different variations too. As long as the patterned openings 3041 match the shapes of the protruding blocks 3026 and are smaller than the size of the sheets, so that the sheets do not move out of the sheet cartridge 304, all the possible modifications belong to the scope of the invention. For example, in FIG. 9(a), the patterned opening 902 of the accepting part of the first housing is a rectangle. In FIG. 9(b), however, the patterned openings 3041 on the accepting part 91 have several geometric shapes or stripes.

While the invention has been described by way of example and in terms of the preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments. To the contrary, it is intended to cover various modifications and similar arrangements as would be apparent to those skilled in the art. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
