Then, the rectifier 215 rectifies the input audio signal and outputs the rectified audio signal to the input port of the CPU 18. Further, the filter 212 extracts only an audio frequency component signal (audio signal) from the input signal, and converts the extracted audio signal through a rectifier 213 into a C signal.
Output to the input port 24 of the PU 18.

Next, the operation of the recording apparatus having the above configuration will be described.
This will be described with reference to the flowcharts shown in FIGS. Here, in the reciprocating operation of the recording head 9,
A so-called one-way printing operation in which a printing operation is performed only during forward movement (when moving in the PT direction shown in FIG. 1) will be described.

The CPU 18 monitors reception of data transmitted from the host computer 17 via the interface 22. When there is a received signal, the transmitted data is temporarily stored in the data memory 21 (steps 1 and 2), and thereafter, the operation of detecting the environmental sound around the recording apparatus main body and the motor speed are performed according to the flowchart shown in FIG. A setting operation is performed (step 3).

That is, the CPU 18 performs sampling and AD conversion on the environmental sound signal input to the input port 24 from the microphone 210 via the audio input circuit 200 (step 601), and determines the end of the AD conversion. (Step 602), the digitized environmental sound signal is referred to (Step 603), and the motor speed Tm10 of the CR motor M1 suitable for the digitized environmental sound signal when the carriage moves forward is set (Step 604). ). Here, the set motor speed Tm10
Changes according to the level of the environmental sound.
The speed is set to be low when the environmental sound is loud, and to be high when the environmental sound is low.

In the above step 601, the environmental sound of the apparatus is converted into a digital quantity by one detection. However, sampling is performed a plurality of times in consideration of measurement accuracy, and data verification and average values are performed. Needless to say, it may be calculated by

In the recording operation, the CPU 18 first activates the motor drive circuit 29a via the output port 29 to drive the CR motor M1 in the forward direction, thereby causing the carriage 6 located at the home position to move forward. Start (Step 4). At the same time, the CPU 18 activates the drive circuit 26 to supply a prescribed heat pulse to the recording head 9 and heats the electrothermal transducer 11 in the recording head 9 to generate bubbles in the ink as described above. The ink is ejected from the ink ejection port 10 by the pressure to perform a one-dot recording operation. The width of the heat pulse, that is, the waiting time t1 from the start of heating of the electrothermal transducer 11 to the stop of heating is measured by a timer provided by hardware or software (steps 5 to 8).

In this way, every time a one-dot recording operation is performed, the dot counter provided in the working memory 20 increases the count value by one (step 9). Then, it is determined whether or not the count value has reached the prescribed number of dots to be formed in one forward period (one scanning period) of the recording head 9 (whether or not the recording cycle counter is full) (step 10). If the number of specified dots has not been reached, the process returns to step 4 and the operations from step 4 to step 9 are repeated.

If it is determined in step 10 that the count value of the dot counter has reached the specified number of dots, the count value of the dot counter is cleared (step 11).

Thereafter, the CPU 18 detects the environmental sound and sets the motor speed in accordance with the detected environmental sound in the same manner as described above in accordance with the flowchart shown in FIG.
However, here, the motor speed TM of the paper feed motor M2
2 and the motor speed TM11 at the time of carriage return movement by the carriage motor M1 are set (step 12).

Thereafter, the CPU 18 controls the motor drive circuit 29
a, the LF motor M2 is driven through the motor drive circuit 29a to feed the recording medium S by one line in the main scanning direction (step 13).
The motor M1 is driven to return the carriage 6 to the home position (carriage return (step 1
4)). Thereafter, the line counter provided in the working memory 20 increments the count value by one each time a recording operation for one line is performed (step 1).
5) The operations of steps 4 to 15 are repeated until the count value reaches a predetermined specified number of lines (step 16), and the recording operation ends when the specified number of lines is reached.

As described above, in the first embodiment, when the ambient sound around the apparatus main body is low and the apparatus is in a quiet state such as at night, the motor speeds of the CR motor M1 and the LF motor M2 are reduced. In addition, the driving noise of the motor, which is a noise source of the recording apparatus, is greatly suppressed, and the deterioration of the acoustic environment is greatly reduced. In particular, in the above embodiment, the CR motor M1 at the time of carriage return is used.
Since the LF motor speed TM11 is also changed in accordance with the environmental sound, the quietness can be maintained more reliably.

Further, in the busy state of the daytime, the motor speed of the CR motor M1 is increased to the maximum source within a range not exceeding the loud environmental sound, so that the daytime work can be performed quickly and efficiently. You can proceed to.

By the way, in the above embodiment, the detection of the environmental sound around the recording apparatus main body is detected by the microphone 210, and the driving speed of the motor is controlled based on the detection result. However, the detection accuracy of the environmental sound becomes extremely important.

For this reason, in the second embodiment of the present invention, in order to always maintain the detection accuracy of the environmental sound properly, before the above-described step 3 in FIG. 5, the environmental sound detection as shown in FIG. Verification operation is performed.

That is, the CPU 18 determines in step 701
Receives, via the input port 24, an environmental sound signal input from the microphone 210 via the audio input circuit 200, performs sampling and AD conversion of the received signal, and outputs the digitized actual environmental sound data. Compare with the specified environmental sound data set assuming a quiet time in advance, and if the actual environmental sound is larger than the specified environmental sound,
Since it is determined that the environmental sound exceeds the quiet state and is in a noisy state (step 704), the subsequent verification operation steps are not performed, and the process proceeds to step 705 to elapse the time set in advance by the timer. Then, the operation from step 701 to step 705 is repeated until the environmental sound is reduced.

In the above steps 701 and 706, the environmental sound of the apparatus is converted into a digital amount by one detection. However, sampling is performed a plurality of times in consideration of measurement accuracy, and data verification and averaging are performed. Needless to say, it may be calculated by

Thereafter, if it is determined in step 705 that the environmental sound is in the silent range, the process proceeds to step 706, and the buzzer is driven (step 706). In this buzzer driving state, the CPU 18 proceeds to steps 707 to 707.
709 converts the environmental sound input from the microphone 210 via the audio input circuit 200 into a digital signal, and digitizes the environmental sound data at the time of actual buzzer driving and the setting set in advance assuming the buzzer driving. The error is calculated by comparing with the environmental sound data. If the error is within a certain error range, it is determined that the environmental sound detection has been properly performed, and the process proceeds to the next step, ie, step 3 or step 12, and the above-described environmental sound detection operation is performed. And setting of motor speed.

In the above steps 701 and 706, the environmental sound of the apparatus is converted into a digital quantity by one detection. However, sampling is performed a plurality of times in consideration of measurement accuracy, and data verification and average value are performed. Needless to say, it may be calculated by

If it is determined in step 10 that the calculated error is within a certain error range, it is determined that a normal detection operation is not being performed, and the motor speed is determined. Without performing the setting operation of
The recording operation is stopped (step 711), and a predetermined display operation is performed on a predetermined display unit (step 722).

As described above, in the second embodiment, it is possible to determine whether or not the environmental sound detection operation is being performed properly, so that the setting operation of the motor speed according to the environmental sound can be appropriately performed. It is possible to more reliably prevent the environment from deteriorating due to noise during the recording operation.

In each of the above embodiments, not only the motor drive control during the forward movement of the carriage 6 but also the motor drive control and the LF motor drive control during the backward movement are performed. Although an extremely good noise prevention effect can be obtained, only one of the motor speed at the time of the forward movement of the carriage 6, the motor speed at the time of the backward movement, and the motor speed of the LF motor M2 is controlled. May be executed, and according to this, the recording operation speed can be maintained while reducing noise.

(Others) The present invention is applicable not only to an ink-jet recording apparatus but also to a recording apparatus employing a thermal transfer method or another recording method. In addition to the so-called bubble jet method in which bubbles are generated in the ink by such thermal energy and the ink is ejected by the pressure of the bubbles, a piezoelectric element is used in the ink flow path of the ink head, and the driving of the piezoelectric element The present invention is also applicable to a device that discharges ink.

However, in the bubble jet method as described above, since the state of the ink is changed by thermal energy such as an electrothermal converter or laser light, an excellent effect can be obtained in the recording apparatus. That is, according to such a method, it is possible to achieve higher density and higher definition of recording.

The typical configuration and principle are described in, for example, US Pat. Nos. 4,723,129 and 4,740.
It is preferable to use the basic principle disclosed in the specification of Japanese Patent No. 796. This method is a so-called on-demand type,
Although it can be applied to any type of continuous type, in particular, in the case of the on-demand type, it can be applied to a sheet holding liquid (ink) or an electrothermal converter arranged corresponding to the liquid path. By applying at least one drive signal corresponding to the recorded information and giving a rapid temperature rise exceeding the nucleate boiling, heat energy is generated in the electrothermal transducer, and film boiling occurs on the heat acting surface of the recording head. Liquid (ink) corresponding to this drive signal on a one-to-one basis.
This is effective because air bubbles inside can be formed. The liquid (ink) is ejected through the ejection opening by the growth and contraction of the bubble to form at least one droplet. When the drive signal is formed into a pulse shape, the growth and shrinkage of the bubble are performed immediately and appropriately, so that the ejection of liquid (ink) having particularly excellent responsiveness can be achieved, which is more preferable. As this pulse-shaped drive signal, those described in U.S. Pat. Nos. 4,463,359 and 4,345,262 are suitable. Further, if the conditions described in US Pat. No. 4,313,124 relating to the temperature rise rate of the heat acting surface are adopted, more excellent recording can be performed.

As the configuration of the recording head, in addition to the combination of a discharge port, a liquid path, and an electrothermal converter (a linear liquid flow path or a right-angled liquid flow path) as disclosed in the above-mentioned respective specifications, U.S. Pat. No. 4,558,333 and U.S. Pat. No. 44,558 which disclose a configuration in which a heat acting portion is arranged in a bending region.
A configuration using the specification of Japanese Patent No. 59600 is also included in the present invention. In addition, Japanese Unexamined Patent Application Publication No. 59-123670 discloses a configuration in which a common slit is used as a discharge portion of an electrothermal converter for a plurality of electrothermal converters, and an aperture for absorbing a pressure wave of thermal energy is provided. The effect of the present invention is effective even if the configuration is based on JP-A-59-138461, which discloses a configuration corresponding to a discharge unit. That is, according to the present invention, recording can be reliably and efficiently performed regardless of the form of the recording head.

Further, the present invention can be effectively applied to a full-line type recording head having a length corresponding to the maximum width of a recording medium on which a recording apparatus can record. Such a recording head may have a configuration that satisfies the length by a combination of a plurality of recording heads, or a configuration as one integrally formed recording head.

In addition, even in the case of the serial type as described above, the recording head fixed to the apparatus main body or the electric connection with the apparatus main body and the ink from the apparatus main body when attached to the apparatus main body. The present invention is also effective when a replaceable chip-type recording head that can be supplied or a cartridge-type recording head in which an ink tank is provided integrally with the recording head itself is used.

Further, it is preferable to add ejection recovery means for the recording head, preliminary auxiliary means, and the like as the configuration of the recording apparatus of the present invention since the effects of the present invention can be further stabilized. If these are specifically mentioned, the recording head is heated using capping means, cleaning means, pressurizing or suction means, an electrothermal transducer, another heating element or a combination thereof. Pre-heating means for performing the pre-heating and pre-discharging means for performing the discharging other than the recording can be used.

The type and number of recording heads to be mounted are not limited to those provided for only one ink corresponding to a single color ink, and for a plurality of inks having different recording colors and densities. A plurality may be provided. That is, for example, the printing mode of the printing apparatus is not limited to a printing mode of only a mainstream color such as black, but may be any of integrally forming a printing head or a combination of a plurality of printing heads. The present invention is also very effective for an apparatus provided with at least one of the recording modes of full color by color mixture.

In addition, in the embodiment of the present invention described above, the ink is described as a liquid. However, an ink which solidifies at room temperature or lower and which softens or liquefies at room temperature may be used. In general, the ink jet method generally controls the temperature of the ink itself within a range of 30 ° C. or more and 70 ° C. or less to control the temperature so that the viscosity of the ink is in a stable ejection range. Sometimes, the ink may be in a liquid state. In addition, in order to positively prevent the temperature rise due to thermal energy by using the energy of the state change from the solid state of the ink to the liquid state, or to prevent the ink from evaporating, the ink is solidified in a standing state and heated. May be used. In any case, the application of heat energy causes the ink to be liquefied by the application of the heat energy according to the recording signal and the liquid ink to be ejected, or to start to solidify when reaching the recording medium. The present invention is also applicable to a case where an ink having a property of liquefying for the first time is used. In such a case, the ink
JP-A-54-56847 or JP-A-60-7
As described in Japanese Patent Publication No. 1260, it is also possible to adopt a form in which the sheet is opposed to the electrothermal converter in a state where it is held as a liquid or solid substance in the concave portion or through hole of the porous sheet. In the present invention, the most effective one for each of the above-mentioned inks is to execute the above-mentioned film boiling method.

In addition, the form of the ink jet recording apparatus of the present invention is not limited to those used as image output terminals of information processing equipment such as computers, copying apparatuses combined with readers and the like, and facsimile apparatuses having a transmission / reception function. It may take a form.
