〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Second
FIG. 3 is a view showing a paper crushing apparatus with a storage mechanism according to an embodiment of the present invention, and FIG. The same reference numerals indicate the same objects throughout the drawings.

In FIG. 2, the information reading means 200 in FIG.
An image scanner 4 is provided as a memory, a memory 6 and a secondary storage device 7 are provided as information storage means 300 in FIG. 1, and a paper crushing means 400 in FIG.
A shredder unit 5 is provided, a tractor unit 3 is provided as a transport unit 500 in FIG. 1, a communication interface 8 is provided as a communication unit 600 in FIG. 1, and a control unit 1 for controlling each unit is provided. Is provided.

2 and 3, the user of the paper crusher with the storage mechanism inserts the paper to be crushed into the paper insertion unit 2 for one sheet.

The paper insertion unit 2 monitors whether or not the paper to be ground is inserted by, for example, a light emitting diode and a photocoupler, and when the paper insertion is detected, notifies the control unit 1 of the insertion of the paper. (Step S1 in FIG. 3).

Upon receiving the paper insertion notification from the paper insertion unit 2, the control unit 1 activates the tractor unit 3 and conveys the paper to be crushed inserted into the paper insertion unit 2 to a readable position of the image scanner 4 (step S2). ).

The image scanner 4 optically reads the information described on the paper conveyed by the tractor unit 3 and transfers the read information to the control unit 1 (step S).
3).

The control unit 1 sequentially accumulates the read information transferred from the image scanner 4 in the memory 6 and, when all the read information for one sheet has been accumulated in the memory 6 (step S4), further controls the tractor unit 3. The paper is driven to transport the paper to be crushed to the shredder unit 5.

The shredder unit 5 crushes the paper conveyed by the tractor unit 3 (Step S6).

The control unit 1 monitors the storage state of the read information in the memory 6, and determines that there is still room in the storage area and that the information to be read from the next sheet can be stored (step S1).
6) The paper insertion unit 2 determines whether the next paper is inserted.
And if it is inserted (step S
7) Repeat step S3 and subsequent steps again.

On the other hand, in step S6, when it is determined that the storage area of the memory 6 has already been filled with the read information and there is no room for storing information to be read from the next sheet, or in step S7.
When the next sheet is not inserted into the sheet insertion unit 2, the control unit 1 stops the tractor unit 3 (step S8), extracts the read information stored in the memory 6, The data is stored in the floppy disk mounted on the storage device 7 (step S9).

In this process, the control unit 1 monitors the storage state of the read information in the secondary storage device 7, and when the read information extracted from the memory 6 exceeds the storage capacity of the floppy disk (step S10), the control unit 1 The user of the paper crusher is notified that the read information to be stored exceeds the storage capacity of the floppy disk (step S11).

By exchanging the floppy disk mounted in the secondary storage device 7, the user who has learned that the storage capacity has been exceeded can store the read information from the crushed paper, and can store new read information.

When the user wishes to reproduce the read information from the crushed paper, the user removes the attached floppy disk from the secondary storage device 7, attaches it to a separately provided word processor or the like, and displays it on the display. Alternatively, a printout is performed by a printer device provided with the word processor.

When a word processor of this type is connected to the communication interface 8 of the paper crusher with a storage mechanism, the control unit 1 extracts read information from the secondary storage device 7 and connects via the communication interface 8. It can also be transferred to a word processor and output.

As is apparent from the above description, according to the present embodiment, the information described on the paper to be ground is read by the image scanner 4 before the grinding, is stored in the memory 6, and is stored in the secondary storage device 7. Since the floppy disk is stored in the attached floppy disk, the floppy disk can be reproduced later by attaching the floppy disk to a separately provided word processor or transferring the stored information to a word processor connected via the communication interface 8. Become.

2 and 3 are merely examples of the present invention, and the reproduction of read information is limited to, for example, a word processor provided separately or connected via a communication interface 8. There is no need to transmit to various necessary information output devices to execute reproduction, etc.
Many other variations are considered, but the effects of the invention remain the same in each case.
