Abstract

A portable facsimile equipment having a plurality of power source connecting portions adapted to be selectively connected to plural kinds of power sources. The facsimile equipment is operable in correspondence with the kind of power source connected thereto. A power source kind detector detects the kind of power source connected. A communication mode storing device stores a communication mode corresponding to the power source connected. A communication mode selecting device accesses the communication mode stored in the communication mode storing device according to a signal from the power source kind detector to automatically set the communication mode. A compact battery can be detachably fixed as one of the power sources. An AC power source can be detachably fixed as one of the power sources. A DC power source can also be detachably fixed as one of the power sources.

Claims

1. A portable facsimile equipment having a plurality of power source connecting portions adapted to be selectively connected to plural kinds of power sources, said facsimile equipment being operable in correspondence with the kind of said power source connected, said portable facsimile equipment comprising:

power source kind detecting means for detecting the kind of said power source connected;

communication mode storing means for storing a communication mode corresponding to said power source connected;

communication mode selecting means for accessing said communication mode stored in said communication mode storing means according to a signal from said power source kind detecting means to automatically set said communication mode;

compact battery means for detachably fixing a compact battery as one of said power sources;

AC power source means for detachably fixing an AC power source as one of said power sources;

DC power source means, other than said compact battery means, for detachably fixing a DC power source as one of said power sources;

wherein when said detecting means detects said AC power source is the power source connected, said communication mode selecting means automatically sets a highest communication speed stored in said communication mode storing means.

2. The portable facsimile equipment according to claim 1, wherein said compact battery means comprises at least one rechargeable battery, and further comprising:

battery voltage detecting means for detecting a voltage of said at least one rechargeable battery; and

a charging circuit for charging said at least one rechargeable battery when said AC power source is the power source connected.

3. A portable facsimile equipment having a plurality of power source connecting portions adapted to be selectively connected to plural kinds of power sources, said facsimile equipment being operable in correspondence with the kind of said power source connected, said portable facsimile equipment comprising:

power source kind detecting means for detecting the kind of said power source connected;

communication mode storing means for storing a communication mode corresponding to said power source connected;

communication mode selecting means for accessing said communication mode stored in said communication mode storing means according to a signal from said power source kind detecting means to automatically set said communication mode;

compact battery means for detachably fixing a compact battery as one of said power sources;

AC power source means for detachably fixing an AC power source as one of said power sources;

DC power source means, other than said compact battery means, for detachably fixing a DC power source as one of said power sources;

wherein when said detecting means detects said DC power source is said kind of power source connected, said communication mode selecting means automatically sets a communication speed lower than that adapted for said AC power source.

4. The portable facsimile equipment according to claim 3, wherein said compact battery means comprises at least one rechargeable battery, and further comprising:

battery voltage detecting means for detecting a voltage of said at least one rechargeable battery; and

a charging circuit for charging said at least one rechargeable battery when said AC power source is the power source connected.

5. A portable facsimile equipment having a plurality of power source connecting portions adapted to be selectively connected to plural kinds of power sources, said facsimile equipment being operable in correspondence with the kind of said power source connected, said portable facsimile equipment comprising:

power source kind detecting means for detecting the kind of said power source connected;

communication mode storing means for storing a communication mode corresponding to said power source connected;

communication mode selecting means for accessing said communication mode stored in said communication mode storing means according to a signal from said power source kind detecting means to automatically set said communication mode;

compact battery means for detachably fixing a compact battery as one of said power sources;

AC power source means for detachably fixing an AC power source as one of said power sources;

DC power source means, other than said compact battery means, for detachably fixing a DC power source as one of said power sources;

wherein when said detecting means detects said DC power source is said kind of power source connected, said communication mode selecting means automatically sets a short break allowable time longer than that adapted for said AC power source.

6. The portable facsimile equipment according to claim 5, wherein said compact battery means comprises at least one rechargeable battery, and further comprising:

battery voltage detecting means for detecting a voltage of said at least one rechargeable battery; and

a charging circuit for charging said at least one rechargeable battery when said AC power source is the power source connected.

7. A portable facsimile equipment having a plurality of power source connecting portions adapted to be selectively connected to plural kinds of power sources, said facsimile equipment being operable in correspondence with the kind of said power source connected, said portable facsimile equipment comprising:

power source kind detecting means for detecting the kind of said power source connected;

communication mode storing means for storing a communication mode corresponding to said power source connected;

communication mode selecting means for accessing said communication mode stored in said communication mode storing means according to a signal from said power source kind detecting means to automatically set said communication mode;

compact battery means for detachably fixing a compact battery as one of said power sources;

AC power source means for detachably fixing an AC power source as one of said power sources;

DC power source means other than said compact battery means, for detachably fixing a DC power source as one of said power sources;

wherein when said detecting means detects said compact battery power source is said kind of power source connected, said communication mode selecting means sets a mode such that automatic receiving is inhibited until timer transmission is ended.

8. The portable facsimile equipment according to claim 7, wherein said compact battery means comprises at least one rechargeable battery, and further comprising:

battery voltage detecting means for detecting a voltage of said at least one rechargeable battery; and

a charging circuit for charging said at least one rechargeable battery when said AC power source is the power source connected.
