Description of the invention (j Background of the invention The present invention relates to recording equipment, which can be driven by a rechargeable battery. The description of the relevant technology is in recording equipment, such as printers, facsimile devices, etc. Information 'is driven by the energy generating member of the recording head, and records the image containing the dot pattern on recording paper, such as paper, plastic film, etc. These recording devices are classified into inkjet devices, line point devices, and thermal devices according to their respective recording methods. Device, etc. In an inkjet recording device, droplets of a recording liquid (ink) are ejected from an ejection port of a recording head, and the ejected droplets are attached to a recording material, such as paper, to perform recording. The inkjet recording head (which uses thermal energy to eject ink droplets) has the advantage that small recording heads can be easily obtained because the ejection ports can be arranged at high density. Therefore, this type of recording head is most suitable for small recording equipment that is easy to mention Although recording equipment generally uses AC power as its main power source, it is mentioned that small-scale recording equipment makes use of Two power sources, namely an AC adapter and a rechargeable battery. When the power of the recording device is provided by the battery, it becomes difficult to drive the device because the output voltage of the battery decreases as the remaining power of the battery decreases. For example, if the 'device abruptly stops during the recording operation, the received recording information is lost. In the case of an inkjet recording apparatus, the ink ejection port of the recording head may be closed without a cover member.

Description of the invention (% Therefore, when the power of the recording equipment, especially the inkjet recording equipment, is provided by the battery, a device shall be provided to charge the battery when the power of the battery falls below a predetermined threshold; Rechargeable battery. In ordinary recording equipment with rechargeable battery and battery charging function, the operation mode of the device is switched from manual to print mode, that is, normal recording mode and a battery charging mode. However, the structure that needs to be manually switched between the print mode and the charging mode requires cumbersome manual operations, resulting in the inability to effectively use the device. If the recording operation and the charging operation are performed in parallel, the device can be effectively used because There is no need to perform a manual switching operation. However, this device requires a large-capacity battery, which can perform recording operations and charging operations in parallel, resulting in an increase in the size and cost of the recording equipment. Moreover, in such recording equipment, it is generally detected during charging. The battery voltage and charging current are measured, and analog to digital conversion is performed by detecting, for example, a fully charged state. However, during the recording operation, when driving a motor and a print head, these components are required. Drive the current, so the status of the signal will fluctuate. If the analog-to-digital conversion circuit operates in this state, the accuracy of the conversion result will be reduced, which will cause the charging control to be unstable. To solve this problem, a method may be considered in which the current consumption in the device is detected, and the charging is automatically performed only when the detected current consumption is below a predetermined threshold. However, a device needs to be set up for this purpose to detect the current consumption in the device very accurately1 leading to an increase in the volume and cost of the device. Moreover, due to the voltage drop caused by the current-sense resistor, the battery voltage dropped below the minimum available 値 at an earlier stage, resulting in a reduction in electricity per charging operation ^ 1¾ Ί κ%.

In the configuration described above, MPU2 is connected to a host device, such as a computer, via PPI, and controls the processing procedures of the programs stored in ROM 5 according to the commands and recorded information signals sent by the host device, and The recording data stored in RA Μ 3 controls the recording operation. Next, the power supply unit 24 will be described in detail with reference to the block diagram shown in FIG. 2. In FIG. 2, an AC adapter 19 and a rechargeable battery 20 are used as power sources to drive the inkjet recording apparatus. A power switch 2 1 selects one of the above two power sources, and should preferably include a DC plug. When the DC plug of the AC adapter 19 is inserted into the DC socket 21, a contact piece 2 1 a is opened, so the AC adapter 19 supplies power. When the DC plug of the AC adapter 19 is not inserted, the contact piece 21a is closed, so the negative electrode of the battery 20 is grounded to GND, and the battery 20 is supplied with power. An input voltage detection circuit 23 detects the output voltage of the supplied power and sends an output signal to the input A / D port of the MPU 2. In this embodiment, a simple input voltage detection circuit 23 is used, which includes a resistor divider to generate a signal representing the detected voltage, and this input is input to MPU2. However, any other suitable method, such as a method using an A / D converter, or a method using a comparator may be considered. MP U 2 receives the output signal from the input voltage detection circuit 23 on the A / D port. By identifying the input voltage, it can be determined whether the supplied power is from the AC adapter 19 or from the rechargeable battery 2 0 . This decision is based on the fact that the voltage from the AC adapter 19 is slightly higher than the voltage from the battery 20, and the paper is owed to you.

Description of the invention (, 〇—Power circuit 2 2 is at the output port of MP U 2. Under the control of 1, the DC output 1 from the power supply is converted to a voltage suitable for driving individual units of the inkjet recording device. A logic power M V ccl is also supplied to the M PU 2 and is even supplied in the power-off mode. The logic voltage Vees and the head voltage Vh are supplied to logic units other than MPU2, such as RAM3, etc., and to the recording head 12 and are only supplied in the power-on mode (that is, the state of recording or waiting for recording). The motor voltage V pp is supplied Go to motors 8, 10, and i 3 (shown in Figure 1). A charging circuit 2 5 charges the rechargeable battery 20 under the control of the output port ◦ 2 of MPU 2. When the AC adapter When the 19 DC plug is pulled out, the charging circuit 2 5 is short-circuited, because The contact sheet 2 1 a is closed. It is explained that the control program using software is used to automatically switch the operation mode between the print mode and the charging mode of the rechargeable battery 20 in the inkjet recording device having the above-mentioned structure. Fig. 3 is a flowchart showing the procedure for charging the MPU 2 of the recording device of this embodiment. In Fig. 3, when the recording device is started, it is determined at step S1 ◦ 1 whether there is a recording command from the main device. If the decision result is negative, the program proceeds to step S 1 ◦ 2, where 'determines whether the recording head is covered. This decision is made by checking the cover flag (this is opened and closed by M pu 2 because MPU 2 controls the cover motor 1 3 'As above) to execute.

At step 104, it is determined whether the AC adapter provides power according to the output signal 1 from the input voltage detection circuit 23. If the result determined in step S 104 is positive, the program proceeds to step s 105, where 'the battery is determined to be charged according to the output signal from the input voltage detection circuit 23 (for example, Check if it is fully charged). If the result of decision at step S 105 is positive, the program proceeds to step S 106, where the charging circuit 25 is controlled to automatically start charging and display charging, and the mode is switched to the charging mode. Or continue charging mode. If the result of the decision at step S 105 or step S 104 is negative, then the program proceeds to step S 107, where the charging is interrupted or stopped and the display of charging is stopped, and the program returns to step S101. In step S103, it is determined whether the time after the request for recording processing has been terminated exceeds a predetermined time, i.e., whether a timeout has occurred. If the decision result in step S 103 is negative, the program returns to step s 1 0 1. If the result of the decision in step S103 is affirmative ', the process proceeds to step S108, where the MPU2 performs a process of closing the cover. Then, in step S109, a cover flag is set. The above procedure of closing the cover when a time-out occurs is called an automatic capping process, which is a familiar concept to prevent the recording head from being clogged when a recording operation is not performed. If the result of the decision at step s 1 ο 1 is affirmative ', the process proceeds to step S 1 10, where it is determined whether or not the recording head is covered according to the covered flag. If the decision result at step s 1 1 0 is negative, that is, if the cover is opened, the procedure proceeds to step s 1 1 5. Such as the decision at step s 1 1 0 to complete the paper music.

If the decision in step S 1 1 1 is negative, the program proceeds to step S 1 1 3, where the cover opening operation is performed. After the flag is reset in step S 1 1 4 The program proceeds to step S 1 1 5. Here, the recording operation is performed according to the recording command from the host device. When the recording operation is completed, the program returns to step S 1 0. If waiting for the next recording command from the host device If a time-out occurs during this period, the cover is closed, and if necessary, the charging operation is resumed, as described above in step S 1 0 2_s 1 009. To encompass the above, in steps S 1 0 1 and s 1 1 0 — 1 1 5, because the print mode is executed, the charging operation is not performed. In steps S101, S102, S103, S108 1 and S10 9, when it is determined that an interruption or the print mode is terminated, the cover closing operation is performed. In steps S101, S102, and S104 — 107, the charging mode switching is performed. As described above Since charging is performed only when the cover is closed, charging can be prevented when the motor and recording head are driven for recording, and therefore, automatic charging is performed with less charging time. Moreover, since the motor and recording head are not affected Charging occurs at the time of driving, so the control is not affected by the noise generated by the driving current of the motor and the recording head, and the accuracy of the detection of the fully charged state is improved.

Description of the invention (1) Recording command of the device, but the recording command can be replaced by a self-test recording command. Of course, the flowchart can also be used for the recording command in step S 101. Situations requiring replacement, where Open the cover temporarily, such as a command to clean the recording head, a command to replace the ink cartridge, a command to start the device, a command to turn off the power to the device, etc .; and the procedure of step S 1 1 1 is The program corresponding to the relevant command is replaced. That is, even if the charge skip control is not performed on the driving requirements of the above-mentioned motor or recording head, the charge skip control can be surely achieved by determining whether the cover is closed. Therefore, the burden of software is small. Moreover, whether the recording head is in the returned position is determined according to whether the cover is closed or not. Therefore, a dedicated sensor is not required to be installed, and therefore the cost does not increase. Although in the above embodiment, whether the recording head is in the retracted position is determined according to whether the cover is closed or not, it is also possible to directly determine whether the recording head is in the retracted position by setting a retracted position sensor. In this case, for example, a home position sensor 7 (shown in Fig. 1) can be used as this sensor. The present invention can of course be applied to a recording device other than an inkjet recording device, using a return position sensor. As described above, according to the present invention, since a device is provided to control the charging function according to the return information indicating whether the recording head is in the retracted position, charging can be prohibited while the motor and the recording head are being driven. Thereby, switching between recording operation and charging operation can be performed automatically without increasing the size and cost of the device. The present invention is particularly applicable to inkjet recording heads and recording equipment, in which thermal energy is generated by using an electrothermal converter, an electro-radiation beam, etc. to change the ejection or ejection-^ This order (please read the notes on the back t, then fill in t Page) Printed by the Consumers' Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs This paper is printed in accordance with the Chinese National Standard (CNS) A4 (210X 297 mm) 4.12894 A7 _______ _________ B7 5. Invention 1 Mao Ming (2) The state of the ink. This is because of the use of these devices, recording of high-density image elements and resolution is possible. (¾ first read the back and pay attention to the #item and then the secret) The typical structure and operating principle of this type of device should be as shown in US Patent Nos. 4,723,129 and 4,740,796 . This principle and structure can be applied to so-called commanded recording systems and continuous recording systems. However, it is especially applicable to the commanded type, because the principle is that at least one driving signal is applied to a liquid (ink) holding plate or an electrothermal converter placed on a liquid channel, and the driving signal is sufficient to cause the temperature to rise rapidly beyond the accumulation The boiling point, thereby, provides thermal energy from the electrothermal converter, and generates film boiling on the heating portion of the recording head, so that bubbles can be generated in the liquid (ink) corresponding to each drive signal. By the bubble's expansion and contraction, the liquid (ink) is ejected through the ejection port to generate at least one droplet. The driving signal should be pulse waveform 1 because the bubble can expand and contract in such a way, and therefore, the liquid (ink) can be ejected by the rapid response. The driving signal of the pulse waveform should preferably be published in full patents 4,4 6 3, 3 5 9 and 4,345 1 262. Moreover, the temperature increasing rate of the heating surface is preferably as published in the full patent No. 4, 3. 1 3 ′ 1 2 4. The structure of the recording head can be as shown in U.S. Patent Nos. 4,5,5,3,3,3 and 4,459,600. Among them, the heating part is placed in the curved part, and the ejection outlet, the liquid channel, and the electrothermal converter The combined structure can be published as the aforementioned patent. Moreover, the present invention can be applied to the structure published in Japanese Published Patent Application No. 1 2 3 6 70/1 9 8 4 in which a common gap is used as the ejection outlets of a plurality of electrothermal converters, and it can be applied to Japanese published applications Book 1 3 8 4 6 1/1 9 8 No. 4 structure 'ϋϋΰΓϊκ'Γϋί) Λ4 叱 指 (2! 〇 × 297 public expense) 4 & 1 屮 ίι'; Μ. Ί ΙΊ: 412894 13 A 7 B7, in which an opening corresponding to the ejection part is configured to absorb the pressure wave of thermal energy. This is because the present invention can perform a recording operation reliably and efficiently regardless of the type of the recording head. The present invention can be applied to a tandem recording head, in which the recording head is fixed on the main assembly; a replaceable block recording head, which is electrically connected to the main device, and can be filled with ink when it is on the main assembly; Or cartridge-type recording head with integrated ink container. A recovery device and / or auxiliary device for pre-operation should be provided because it can further stabilize the effect of the present invention. Examples of this device include the cover of the recording head Device Placement, depression or suction device, and pre-heating device, this can be an electrothermal converter, an additional heating element, or a combination thereof. Moreover, the device for performing pre-spraying (not used for recording operation) can stably record operation. The mounting variation of the recording head may include a single recording head corresponding to a single-color ink, or a plurality of recording heads corresponding to a plurality of ink materials having different recording colors or densities. The present invention can also be effectively applied to a recording head having At least one monochrome mode of black, a multi-color mode of ink materials of different colors, and a full-color mode in which various colors are mixed-the device 'this can be an integrally formed recording unit, or a combination of multiple recording heads. Moreover, although the above Note that liquid ink is used, but it is also possible to use ink materials that are solid at room temperature but liquid at room temperature. Because the ink of this recording device should be kept in the temperature range of 30 ° C and 70 ° C 'Stable ink viscosity' produces stable jets, so when the recording signal of the present invention is applied, the ink in this temperature range is liquid.

Description of the invention (4) A7 Π7 ′ consumes heat energy and rises to high temperature due to heat energy and its evaporation. ‘When the ink is liquefied, and when the recording material is reached, the present invention also allows the ink material to be a solid material, or a heat exchanger. The inkjet recording output terminal is familiar with the information sending from the drawings, and the charging operation or the best, although it has been referenced and is not limited to the patented here, the improved liquefaction ink begins to solidify and can be applied to porous plates such as Japan The equipment of the above-mentioned technology can be used in the same way as the image and receiving power. The technology mode is not the details or scope described here. The patent / 19 is most effective as an information reader. Biography expresses its key points. The nodules of the table, and the surroundings of the ink from the solid to the liquid, really prevent the ink level. Another ink material is cured when it is left to prevent the situation, and water can be ejected in response to the application of a recording signal to generate thermal energy. Another ink material may be an ink material which is liquefied by thermal energy. Such a through-hole or notch remains liquid in application No. 56847/85. The face of the plate is a thin film boiling system. Processing device, a copying device such as a computer or other combination, or as a real machine = individual components for the structure and operation of the recording device. The invention is illustrated by implementing the invention, but this application is intended to cover The following application is modified or changed. 1-! . τΛί ^ I ί Order ί HI J a * (Read next to me first and then note ^^ item and ^ write this page) i.?. 乂 ’j
