Claim 9

An apparatus according to claim 7, wherein said display means displays data indicative of the status of said apparatus, including data indicative of apparatus error.

Claim 10

An apparatus according to claim 1, further comprising first display means for displaying which one of the first or second cartridge is loaded.

Claim 11

An apparatus according to claim 1, further comprising second display means for displaying that no cartridge is loaded.

Claim 12

An apparatus according to claim 9 where said first display means displays whether said first or second cartridge provides recording means for copying, reading, printing, or reading and printing.

Claim 13

An apparatus according to claim 10, where said second display means also displays messages as a result of a diagnosis of the apparatus or operational status of said first or second cartridge.

Claim 14

An image recording apparatus comprising: original scanning means for scanning an original image by light exposure; a first cartridge detectably loadable in a holding portion of said apparatus and provided with recording means for recording an image on a sheet by an electrophotographic process, thereby reproducing, on said sheet, an image of the original image scanned by said original scanning means; a second cartridge loadable in the holding portion of said apparatus in place for said first cartridge and provided with converter means for reading image information of the original image and converting the same into an electrical signal and an interface for outputting the electrical signal to an external device; guide means for loading or detaching said first or second cartridge into or from said holding portion; control means for enabling the copying and reading of the original image utilizing commonly said original scanning means when said first cartridge is loaded and when said second cartridge is loaded; and an operational panel including regulating means for manually regulating a density of the copied image when said first cartridge is loaded; a developing bias is controlled in accordance with a signal from the regulating means when said first cartridge is loaded, and wherein a reference level for conversion by the converter means is determined in accordance with a signal from said regulating means when said second cartridge is loaded.

Claim 15

An image recording apparatus comprising: original scanning means for scanning an original image by light exposure; a first cartridge detectably loadable in a holding portion of said apparatus and provided with recording means for recording an image on a sheet by an electrophotographic process, thereby reproducing, on said sheet, an image of the original image scanned by said original scanning means; a second cartridge loadable in the holding portion of said apparatus in place for said first cartridge and provided with converter means for reading image information of the original image and converting the same into an electrical signal and an interface for outputting the electrical signal to an external device; guide means for loading or detaching said first or second cartridge into or from said holding portion; control means for enabling the copying and reading of the original image utilizing commonly said original scanning means when said first cartridge is loaded and when said second cartridge is loaded; and an operational panel including regulating means for manually regulating a density of the copied image when said first cartridge is loaded; a developing bias is controlled in accordance with a signal from the regulating means when said first cartridge is loaded, and wherein a reference level for conversion by the converter means is determined in accordance with a signal from said regulating means when said second cartridge is loaded.

Claim 16

An apparatus according to claim 13, wherein said operational panel further comprises a plurality of key input means for manually inputting processing instructions, and wherein said control means starts the scanning by the original scanning means in response to the operation instruction of one of the key input means when the first cartridge is loaded, and wherein said control means starts the scanning by the original scanning means in response to a read instruction from the external device when the second cartridge is loaded.

Claim 17

An apparatus according to claim 14, wherein the instruction inputted by one of the key input means is effective only when the first cartridge is loaded and non-effective when the second cartridge is loaded.

Claim 18

An apparatus according to claim 13, further comprising first display means for displaying which one of the first or second cartridges is loaded.

Claim 19

An apparatus according to claim 16, further comprising second display means for displaying that no cartridge is loaded.
