Abstract

PURPOSE:To save electricity when a printing apparatus is not used by supplying electricity to each part except a printing controlling circuit part by a printing informing signal and stopping the same by a printing finishing signal. CONSTITUTION:When a printing instruction by a printing controlling signal from a data processing device is transmitted to a printing controlling signal circuit part 3, the circuit part 3 generates a printing informing signal to a power source part 5. The power source part 5 turns ON a DC power source on a power line 10 upon receipt of the printing informing signal, so that the DC power is sent to a memory circuit part 1, a printing part 2 and a fan part 4. After the printing information is stored from the data processing device into the memory circuit part 1, the information is sent out as a printing data to the printing part 2. On the other hand, the circuit part 3 generates a controlling signal to the printing part 2 upon receipt of the printing controlling signal from the data processing device, whereby printing, changing of a line of a page, etc., is controlled. When an instruction to finish printing is sent to the printing controlling circuit part 3, the circuit 3 generates a printing finishing signal to the power source part 5.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to t-source control in a printing device.

(Prior Art) A conventional printing device of this type is #f as shown in FIG. In FIG. 2, 30 is a memory circuit section, 31
is a printing control circuit section, 32 is a printing section, 37 is a power supply section, 40
is the fan section.

Conventionally, this camphor printing device is connected to a power line 3 as shown in FIG.
8, the AO power is supplied to the source 37.
When the power is turned on, 00 is sent to each part via the power line 39.
1 [Source supplied.

The system waits for activation from the data processing device.

When activated from the data processing device, print information is stored in the storage circuit section 30 from the signal line 33. On the other hand, the print control signal from the signal line 34 is input to the print control circuit section 31, becomes a control signal on the m & I 36, controls the print m32, and prints the print data from the memory circuit section 30 to the signal line 35. Ru.

(Problem A to be Solved by the Invention) In the conventional printing device described above, the data processing device
I! even when the device is not in use! Since it is necessary to turn on the L source, there is a drawback that unnecessary power is required. Also, since the fan is rotating, it has the disadvantage of being noisy.

An object of the present invention is to eliminate the print control circuit section <q! It is an object of the present invention to provide a printing device configured to eliminate the above-mentioned drawbacks and to suppress wasteful power consumption by turning on the power of the rm in response to a print advance signal and disconnecting it in response to a print end signal.

(Means for Solving Problem A) A printing apparatus according to the present invention is configured to include a storage circuit section, a print control circuit section, a printing section, a fan section, and a power supply section.

The storage circuit section Fi is for storing print information from the data processing device.

The print control circuit unit is for controlling printing based on a print control signal from the data processing device.

The printing section is the ninth section for printing print data.

The fan section is for cooling the electronic circuits of each section.

The power supply section is for constantly supplying power to the printing control circuit section, and for turning on the power to the storage circuit section, printing section, and fan section in response to a print advance signal, and disconnecting power in response to a print end signal.

(Example) Next, one embodiment of the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a printing apparatus according to the present invention. In FIG. 1, 1 is a storage circuit section, 2 is a printing section, 3 is a printing control circuit section, 4 is a fan section, and 5 is a power supply section.

AC power is supplied via the power line 14! is supplied to the image unit 5, and when the AU power is turned on, the power supply unit 5 supplies an initial 1)0 power to the print control circuit unit 3 via the power 1i13. As a result, the print control circuit s3 becomes ready and waits for a print control signal given from the data processing device via the signal [8. At this time, power IIi! 10
The L)-0 power supply supplied by is in the off state.

When an instruction to perform printing is transmitted to the print control circuit section 3 by a print control signal given from the data processing device via the signal line 8, the print control circuit section 3 A print notice signal is sent to the

The power supply @ 5 sets the power 1 [1 on 10] (] power # on in response to the print notice signal on the signal line ll, and supplies power to the memory circuit sections i, - printing section 2.G, and fan section 4. Against L) 0
Supply power.

After that, the data processing device sends a signal 11! After the print information sent out on i16 is stored in the storage circuit section l, it is sent out to the print section 2 from the signal line 7 as print data. On the other hand, in response to the print control signal sent from the data processing device onto the signal line δ, the print control circuit unit 3 sends a control signal to the print s2 via the signal 119t-, and controls printing, line feed, page feed, etc. conduct.

When the print control circuit section 3 is instructed to end printing by the print control signal sent from the data processing device to the signal @8, the print control circuit section 3 sends a print end signal to the power supply section 5 via the signal line 121. Send. In response to the print end signal on the signal line 12, the power supply section 5 turns off the Dog source on the power supply l510, and stops the DC power supply II& to each section K) iv except the print control circuit section 3.

(Effects of the Invention) As explained above, the present invention provides printing! By turning on the power supply in the valley except for the Ij control circuit section in response to the print advance signal and disconnecting it in response to the print completion signal], power can be saved when the printing device is not in use, and fan rotation noise can be prevented. There is.
