DETAILED DESCRIPTION
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”
Referring to FIG. 1, an embodiment of a document storage device for a printer includes a control unit 10 and a document distributing and storage unit 20. The control unit 10 includes a selection interface 11. The selection interface 11 is used to choose a storage position of printed documents. The control unit 10 controls the document distributing and storage unit 20 to store the printed documents in either one destination, a second destination, or a third destination according to the choice in the selection interface 11.
Referring to FIGS. 2 and 3, the document distributing and storage unit 20 includes a document storage rack 30, a transmitting roller 40, a plurality of pressing rollers 50, and a document distributing apparatus 60.
An inner room of the document storage rack 30 is divided by a plurality of partition pieces 35. In one embodiment, there are two partition pieces 35 to divide the inner room of the document storage rack 30 into three storage spaces: a first storage space 31, a second storage space 32, and a third storage space 33. The first storage space 31 is located above the second storage space 32. The third storage space 33 is located below the second storage space 32. A side of the first storage space 31 is equipped with a first protecting door 311. The first protecting door 311 protects the first storage space 31 from any unauthorized access. The first protecting door 311 can only be opened by authorized persons to access and retrieve printed documents in the first storage space 31. A side of the second storage space 32 is equipped a second protecting door 321. The second protecting door 321 protects the second storage space 32 from any unauthorized access. The second protecting door 321 can only be opened by persons who are authorized to access and retrieve printed documents in the second storage space 32. A side of the third storage space 33 defines an opening 331 through which the third storage space 33 can be accessed freely, by any persons.
The transmitting roller 40 transmits the printed document to the document storage rack 30. The plurality of pressing rollers 50 are on the periphery of the transmitting roller 40 and keep the front of the printed document moving around the transmitting roller 40 as it rotates.
The document distributing apparatus 60 is located between the transmitting roller 40 and the document storage rack 30 and is aligned to the document storage rack 30. The document distributing apparatus 60 includes a first distributing roller 61 and a second distributing roller 62. The first distributing roller 61 is connected to a controlling pole 70. The second distributing roller 62 is connected to a stationary pole 621. One end of a connection pole 71 is pivotally connected on a middle portion of the controlling pole 70. Another end of the connection pole 71 is pivotally connected to a bottom end of the stationary pole 621. The controlling pole 70 can be controlled by the control unit 10 to move up and down. Therefore, the first distributing roller 61 moves together with the controlling pole 70 among a first position, a second position, and a third position. At the first position, the first distributing roller 61 is aligned along a tangential line from the transmitting roller 40 to the first storage space 31, to distribute the printed document to the first storage space 31. At the second position, the first distributing roller 61 is aligned along a tangential line from the transmitting roller 40 to the second storage space 32, to distribute the printed document to the second storage space 32. At the third position, the first distributing roller 61 is aligned along a tangential line from the transmitting roller 40 to the third storage space 33, to distribute the printed document to the third storage space 33.
Referring to FIGS. 4 and 5, in work, the printed document is transmitted to the transmitting roller 40 and the plurality of pressing rollers 50. The transmitting roller 40 rotates to bring the front of the printed document around to the second distributing roller 62 and the first distributing roller 61.
When the first distributing roller 61 is located at the first position, the first distributing roller 61 distributes the printed document in the first storage space 31. If an authorized user needs to pick the printed document from the first storage space 31, such authorized user can open the first protecting door 311 by a first key or a first password to fetch the printed document.
When the first distributing roller 61 is located at the second position, the first distributing roller 61 distributes the printed document in the second storage space 32. If an authorized user needs to pick the printed document from the second storage space 32, such an authorized user can open the second protecting door 321 by a second key or a second password to fetch the printed document.
When the first distributing roller 61 is located at the third position, the first distributing roller 61 distributes the printed document in the third storage space 33. The printed document can be accessed by any person without a key or password.
The document storage device can store the printed document in the first storage space 31, or in the second storage space 32, or in the third storage space 33 according to a user's choice in the selection interface 11.
It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
