Claims
- 1. An electronic apparatus connected to an external apparatus to perform a predetermined process, said electronic apparatus being equipped with a chargeable battery from which a power is supplied to respective units of said electronic apparatus, and being initialized by an initialization signal from the external apparatus, comprising:
- instruction means for instructing a charge for said battery;
- charging means for performing the charge for said battery in accordance with an instruction from said instruction means; and
- control means for inhibiting a response to the initialization signal while said charging means performs the charge for said battery.
- 2. An apparatus according to claim 1, wherein in response to the initialization signal during non-charge for said battery, said control means to interrupt a process now in execution and performs an initialization by an interruption process.
- 3. An apparatus according to claim 2, wherein said control means inhibits the interruption by said initialization signal.
- 4. An apparatus according to claim 1, wherein said control means has means for inhibiting entrance of the initialization signal during the charge for said battery.
- 5. An apparatus according to claim 1, wherein said control means controls operations of the respective units of said electronic apparatus.
- 6. An apparatus according to any one of claims 1 to 5, wherein said electronic apparatus is an ink jet printer which records an image on a recording material by ejecting an ink.
- 7. An apparatus according to claim 6, wherein the ink is ejected by causing a status variation of the ink using thermal energy.
- 8. An electronic equipment which receives power from a chargeable battery, comprising:
- process means for conducting a predetermined process;
- control means for controlling said process means, wherein said control means generates a signal of a predetermined period in normal operation, and does not generate the signal of the predetermined period in abnormal operation;
- signal output means for outputting a charge instruction signal for instructing charging by receiving the signal of the predetermined period from said control means; and
- charging means for charging the battery in response to the charge instruction signal from said signal output means.
- 9. An apparatus according to claim 8, wherein said process means includes means for recording an image on a recording medium in accordance with data.
- 10. An apparatus according to claim 9, wherein said recording means records an image by ejecting ink droplets in accordance with the data.
- 11. An electronic equipment which receives power from a chargeable battery, comprising:
- process means for conducting a predetermined process in accordance with data inputted from an external apparatus;
- control means for controlling said process means, wherein said control means outputs an instruction signal for instructing charging, and conducts a predetermined initialization process in accordance with an initialization signal from said external apparatus;
- charging means for charging the battery in accordance with the instruction signal; and
- inhibit means for inhibiting the predetermined initialization process based on the initialization signal during the charging of said battery.
- 12. An apparatus according to claim 11, wherein in response to the initialization signal during non-charge for said battery, said control means interrupts a process now in execution and performs said predetermined initialization process by an interruption process.
- 13. An apparatus according to claim 12, wherein said inhibit means inhibits the interruption process by said initialization signal.
- 14. An apparatus according to claim 11, wherein said inhibit means has means for inhibiting entrance of the initialization signal during the charge for said battery.
- 15. An apparatus according to claim 8, wherein said process means comprises record means for recording an image on a recording medium in accordance with the data.
- 16. An apparatus according to claim 15, wherein said record means records an image on the recording medium by ejecting ink droplets in accordance with the data.
- 17. An apparatus according to claim 16, wherein said record means ejects ink droplets from at least one ink orifice by causing a change in ink state using thermal energy.
- 18. An apparatus according to claim 8, wherein said signal output means outputs the charge instruction signal during receiving of the signal of predetermined period, and does not output the charge instruction signal after the signal of predetermined period is not received.
- 19. An apparatus according to claim 8 or claim 18, wherein said charging means is provided with a switching means for switching in accordance with the charge instruction signal outputted from said signal output means, between a state of the supply of a charge current to the battery and a state of the cut-off of the charge current to the battery.
- 20. An apparatus according to claim 8 or claim 18, wherein said charging means comprises a charging circuit for charging said battery, and a switching circuit for performing a switching operation between a state of supply of power to said charging circuit and a state of the cut-off of the power to said charging circuit, said switching circuit performing the switching operation in accordance with the charge instruction signal outputted from said signal output means.
- 21. An apparatus according to claim 10, wherein said record means ejects ink droplets by causing a change in ink state using thermal energy.
