Abstract

A printer of the present invention allows a plurality of sheet feeding apparatuses, each having a particular sheet feed speed range adaptive to a plurality of print speeds, to be selectively connected thereto. When any one of the sheet feeding apparatuses is connected to the printer, a controller automatically sets a print speed range on the printer in accordance with print speed range information corresponding to the sheet feeding apparatus.

Claims

1. A printer to which a plurality of sheet feeding apparatuses, each having a particular number of sheet feed speeds, are connectable, said printer comprising:

apparatus selecting/changing means for allowing any one of the plurality of sheet feeding apparatuses to be selected or changed;

print speed display means;

print speed selecting/changing means for allowing anyone of a plurality of print speeds to be selected or changed; and

control means for displaying on said print speed display means a print speed matching a highest sheet feed speed available with the sheet feeding apparatus selected.

2. The printer as claimed in claim 1, wherein said print speed display means displays the print speed in terms of a number of print speeds for a unit time.

3. The printer as claimed in claim 1, further comprising a control panel with which said apparatus selecting/changing means, said print speed display means and said print speed selecting/changing means are integrally constructed.

4. The printer as claimed in claim 1, wherein said apparatus comprises a stencil printer.

5. A printer to which a plurality of sheet feeding apparatuses, each having a particular number of sheet feed speeds, are connectable, said printer comprising:

apparatus selecting/changing means for allowing any one of the plurality of sheet feeding apparatuses to be selected or changed;

print speed display means;

print speed selecting/changing means for allowing anyone of a plurality of print speeds to be selected or changed; and

control means for automatically changing, when the sheet feeding apparatus once selected is changed to another sheet feeding apparatus, and if a print speed matched with a previous sheet feeding apparatus is a highest print speed, said print speed to a highest print speed matching said another sheet feeding apparatus.

6. The printer as claimed in claim 5, further comprising a control panel with which said apparatus selecting/changing means, said print speed display means and said print speed selecting/changing means are integrally constructed.

7. The printer as claimed in claim 5, wherein said apparatus comprises a stencil printer.

8. A printer to which a plurality of sheet feeding apparatuses, each having a particular sheet feed speed range adaptive to a plurality of print speeds, are selectively connectable, said printer comprising:

storing means for storing beforehand print speed range information each matching the sheet feed speed range of a particular sheet feeding apparatus; and

control means for selecting, when any one of said sheet feeding apparatuses is connected to said printer, a print speed range of said printer in accordance with the print speed range information corresponding to said sheet feeding apparatus connected to said printer.

9. The printer as claimed in claim 8, wherein a highest speed of the print speed range is variable in matching relation to the sheet feeding apparatus or a sheet discharging apparatus connected to said printer.

10. The printer as claimed in claim 8, further comprising connection identifying means for identifying at least one of the sheet feeding apparatus and a sheet discharging apparatus connected to said printer, said control means setting the print speed range in accordance with the print speed range information corresponding to at least one of said sheet feeding apparatus and said sheet discharging apparatus.

11. The printer as claimed in claim 10, wherein said connection identifying means comprises a connection identifying circuit configured to identify connection and a type of at least one of the sheet feeding apparatus and the sheet discharging apparatus connected to said printer by communicating with said at least one apparatus.

12. The printer as claimed in claim 10, wherein said connection identifying means comprises selecting means configured to select information of at least one of the sheet feeding apparatus and the sheet discharging apparatus stored in said storing means beforehand.

13. The printer as claimed in claim 12, further comprising alarm display means, said control means causing, when the print speed range selected by said selecting means and a print speed range corresponding to at least one of the sheet feeding apparatus and the sheet discharging apparatus connected to said printer do not match each other, said alarm display means to urge an operator of said printer to change said print speed range selected by said selecting means.

14. The printer as claimed in claim 8, wherein said printer comprises a stencil printer.

15. A printer to which a plurality of sheet discharging apparatuses, each having a particular sheet discharge speed range adaptive to a plurality of print speeds, are selectively connectable, said printer comprising:

storing means for storing beforehand print speed range information each matching the sheet discharge speed range of a particular sheet discharging apparatus; and

control means for selecting, when any one of said sheet discharging apparatuses is connected to said printer, a print speed range of said printer in accordance with the print speed range information corresponding to said sheet discharging apparatus connected to said printer.

16. The printer as claimed in claim 15, wherein a highest speed of the print speed range is variable in matching relation to the sheet discharging apparatus or a sheet feeding apparatus connected to said printer.

17. The printer as claimed in claim 15, further comprising connection identifying means for identifying at least one of the sheet discharging apparatus and a sheet feeding apparatus connected to said printer, said control means setting the print speed range in accordance with the print speed range information corresponding to at least one of said sheet discharging apparatus and said sheet feeding apparatus.

18. The printer as claimed in claim 17, wherein said connection identifying means comprises a connection identifying circuit configured to identify connection and a type of at least one of the sheet discharging apparatus and the sheet feeding apparatus connected to said printer by communicating with said at least one apparatus.

19. The printer as claimed in claim 17, wherein said connection identifying means comprises selecting means configured to select information of at least one of the sheet discharging apparatus and the sheet feeding apparatus stored in said storing means beforehand.

20. The printer as claimed in claim 19, further comprising alarm display means, said control means causing, when the print speed range selected by said selecting means and a print speed range corresponding to at least one of the sheet discharging apparatus and the sheet feeding apparatus connected to said printer do not match each other, said alarm display means to urge an operator of said printer to change said print speed range selected by said selecting means.

21. The printer as claimed in claim 15, wherein said printer comprises a stencil printer.
