Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording device that can use an AC adapter power supply and a battery power supply, and an image communication device equipped with this recording device.

[0002]

2. Description of the Related Art Conventionally, for example, in a recording device mounted on a personal word processor having a charging function, when the word processor is used while being connected to an outlet for home use, AC power is supplied from a household AC100V power supply.
When a word processor is used in the field, for example, a printing operation is performed by a power source (hereinafter, referred to as an AC adapter power source) obtained through an adapter, a power source of, for example, 12 V (hereinafter, referred to as a battery power source) using a precharged battery. The print operation is performed by.

By the way, even in a device capable of using such an AC adapter power supply and a battery power supply, conventionally,
Regardless of the type of power supply used, processing was performed using a fixed printing method.

[0004]

However, in the above-mentioned conventional recording apparatus, when the power consumption greatly changes depending on the black rate of the print data, such as a thermal head printer, the capacity of the battery power source depends on the black rate. In addition, the voltage may be significantly reduced, and stable printing operation may not be performed. Therefore, a method of avoiding the consumption of the battery power source by performing a certain thinning-out process according to the black ratio can be considered.

However, when such a thinning-out process is applied, there is a disadvantage that print data is thinned out when printing is performed by the AC adapter power supply, which causes meaningless deterioration of image quality.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a recording device capable of performing a printing process by an optimal printing method according to the type and state of a power source and an image communication device equipped with the recording device.

[0007]

SUMMARY OF THE INVENTION The present invention relates to a recording apparatus which can use an AC adapter power source and a battery power source,
Whether the AC adapter power supply or the battery power supply is in use is automatically determined, and when the AC adapter power supply is used, printing is performed by a normal method, and when the battery power supply is used, printing is performed by a certain thinning process. It is intended to obtain a high quality printed image by printing with the AC adapter power source while avoiding consumption of the battery power source.

For example, in normal printing, all data is printed regardless of the black rate, and when using a battery power source, the thinning process is performed when the black rate is 50% or more.
Alternatively, in normal printing, when the black ratio is 50% or more, the thinning is performed by changing the thinning condition such that the printing is performed by thinning the entire print regardless of the black ratio when using the battery power source. Power consumption can be reduced.

The type of power source to be used can be determined not only by automatic determination, but also based on the user's power source selection operation. Further, the normal printing method and the thinning method can be selected by the user. Note that specific thinning-out conditions and the like are not limited to the above, and can be appropriately adopted.

Further, according to the present invention, in a recording apparatus which uses a car battery as a power source, a means for switching the printing method according to the capacity of the car battery is provided.

At 07, a recording paper insertion sound for prompting the setting of recording paper is sounded, and the process returns to S105 to determine the elapse of T1 time.

If T1 time has elapsed, S
At 108, DCN is transmitted, and at S109,
Sounds an error sound, lights the error lamp, and returns to the standby state.

Next, FIG. 13 is a flow chart showing details of the copy operation in S33 and S46.

First, when the copy mode is entered, it is determined in S200 whether the BAT / AC signal at the contact portion is 0 or not. FIG. 15 is a circuit diagram showing the principle of detecting a BAT / AC signal.

In FIG. 15, the BAT / AC signal of the main body is pulled up to + 5V and is input to the input port 98 of the CPU 11. When the AC adapter power supply is connected, the BAT / AC signal is input via the contact portion. Since the BAT / AC signal is connected to the ground, the BAT / AC signal = 0.

When the battery power source is connected, the BAT / AC signal is opened via the contact portion, so that the BAT / AC signal = 1 due to the pull-up in the main body portion.

Further, when the car battery power source is connected, when the capacity is large due to the capacity of the car battery, the switch 99 for switching the car battery power source is turned on, and the BAT / AC signal = 0 via the contact portion. When the capacity is small, the car battery power source changeover switch 99 is turned off, and the BAT / AC signal =
It becomes 1.

As described above, the changeover switch 99 is provided in the car battery power source to change the capacity of the car battery to the CPU 11.
Then, the current consumption is switched based on the value specified by the user, and the printing mode to be described later is selected, whereby energy saving based on the user's intention can be realized.

If the BAT / AC signal = 0 in S200, the full print mode is set in S201. If the BAT / AC signal = 1, in S203, it is determined whether or not it is the economy mode. If it is the economy mode, the thinning mode for thinning and printing is set in S205, and if it is not the economy mode, in S204. The mode is set to the thinning printing only when the black ratio of the original is 50% or more.

That is, in the second embodiment, unlike the first embodiment, the normal printing mode for the AC adapter power supply is a printing method in which thinning is performed only when the black ratio is 50% or more, and the battery power supply is used. The print mode for printing (that is, the economy mode) is a printing method in which thinning is performed regardless of the black ratio.

FIG. 22 is a schematic diagram showing an example of an image in the normal print mode and an image in the print mode for the battery power source. As shown in the figure, even in the normal print mode, the portion with a black ratio of 50% or more is printed by thinning. On the other hand, in the print mode for battery power, the entire image is thinned out regardless of the black ratio. The details of the thinning-out are the same as those in the first embodiment, for example.

As described above, S201, S204,
After any mode is set in S205,
In S202, the copying operation is performed, and after the copying operation is completed, the operation returns to the standby state.

The present invention is not limited to the above-mentioned facsimile machine, but can be widely applied to devices using an AC adapter power supply and a battery power supply or a car battery power supply.

[0131]

According to the present invention, by changing the printing method when the AC adapter power source is used and when the battery power source is used, it is possible to reduce the consumption of the battery power source and to secure good quality printing by the AC adapter power source. There is an effect that can be.
