Next, the operation of the ink jet printer system 11 of this embodiment will be described.
When the ink jet printer system 11 is used in a stationary state, first, the ink jet printer 12 is arranged on the ink recovery device 14 and the ink recovery device 14 is mounted on the lower side of the ink jet printer 12. . At this time, the ink recovery device 14 is positioned with respect to the ink jet printer 12 by inserting the first protrusions 15 c into the second recesses 70 a. By this positioning, the ink collection side connection portion 31 is reliably pressed against the ink collection connection member 71, and the ink collection side connection portion 31 and the ink collection connection member 71 are smoothly connected.

  That is, when the ink collection side connection portion 31 is pressed against the ink collection connection member 71 from the state where the ink collection side connection portion 31 and the ink collection connection member 71 are not connected (the state shown in FIG. 5). The ink collection side valve 45 is pushed upward by the insertion body 77 against the urging force of the coil spring 46. At the same time, the ink recovery valve 80 is pushed downward by the recovery lower flange 44 against the urging force of the coil spring 46.

  As a result, the ink collection side connection portion 31 and the ink collection connection member 71 are connected in a state where the ink collection side valve 45 and the ink collection valve 80 are opened (see FIG. 6), and the inside of the cap 29 and the discharge tube 30 are connected. The inside of the ink collecting side connecting portion 31, the inside of the ink collecting connecting member 71, and the inside of the ink collecting tube 74 are in communication with each other.

  When the ink recovery device 14 is mounted on the lower side of the ink jet printer 12, the electrical connection terminal 86 and the electrical connection terminal 84 come into contact with each other, and the ink jet printer 12 and the ink recovery device 14 are electrically connected by this contact. Is done.

  Subsequently, the ink supply device 13 is disposed on the ink jet printer 12 and the ink supply device 13 is mounted on the upper side of the ink jet printer 12. At this time, the ink supply device 13 is positioned with respect to the ink jet printer 12 by inserting the second protrusions 50b into the first recesses 15b. By this positioning, each ink supply connection member 55 is surely pressed against each ink supply side connection portion 28, so that each ink supply side connection portion 28 and each ink supply connection member 55 are smoothly connected. Is done.

  That is, each ink supply connection member 55 is connected to each ink supply side connection portion from the state where each ink supply side connection portion 28 and each ink supply connection member 55 are not connected to each other (the state shown in FIG. 3). When pressed against 28, the ink supply side valve 41 is pushed downward by the insertion body 60 against the urging force of the coil spring 40. At the same time, the ink supply valve 63 is pushed upward against the urging force of the coil spring 64 by the supply upper flange 38.

  Thereby, each ink supply side connection portion 28 and each ink supply connection member 55 are connected in a state where the ink supply side valve 41 and the ink supply valve 63 are opened (see FIG. 4). Accordingly, each supply ink tank 51, each ink supply tube 56, each insertion passage 54a, each ink supply connection member 55, each ink supply side connection portion 28, and each sub ink tank 27 are mutually connected. It becomes a state of communication.

  When the ink supply device 13 is mounted on the upper side of the ink jet printer 12, the charging side connection terminal 83 and the charging connection terminal 85 come into contact with each other, and the ink jet printer 12 and the ink supply device 13 are electrically connected by this contact. Connected. As a result, the ink jet printer 12, the ink supply device 13, and the ink recovery device 14 are electrically connected to each other.

  Then, when the plug 59 is inserted into an unillustrated outlet (power source), power is supplied to the charger 57, whereby the rechargeable battery 36 and the rechargeable battery 76 are charged and power is supplied to the entire inkjet printer system 11. Is done. At this time, the pressure pump 52 is driven for a predetermined time so that ink is replenished (supplied) in each sub ink tank 27 by the amount of ink that can be ejected with the amount of power charged in the rechargeable battery 36. As a result, the ink in each supply ink tank 51 is pressurized for a predetermined time, and the ink is replenished (supplied) in each sub ink tank 27 by the amount of ink that can be ejected with the amount of power charged in the rechargeable battery 36. The

  Thereby, the ink jet printer system 11 can be used in a stationary state. When the ink jet printer 12 prints on the recording paper 20 and the ink in each sub ink tank 27 is consumed, each sub ink has an amount of ink that can be ejected with the amount of power charged in the rechargeable battery 36. The pressure pump 52 is driven so that the ink is replenished (supplied) into the tank 27.

  As a result, the ink in each supply ink tank 51 is pressurized, and each sub ink tank 27 is quickly replenished (supplied). Therefore, the ink jet printer 12 is always in a state where ink is stored in each sub ink tank 27 by the amount of ink that can be ejected by the amount of power charged in the rechargeable battery 36.

  When cleaning the recording head 25, first, the carriage 22 is moved to the non-printing area. Then, the nozzle forming surface 25 a (each nozzle 26) of the recording head 25 is sealed with the cap 29. When the tube pump 75 is driven in this state, the inside of the cap 29 is depressurized, and the thickened ink and air bubbles in each nozzle 26 are sucked from the inside of the cap 29 toward the collection container 72 to enter the collection container 72. To be recovered. The ink collected in the collection container 72 is absorbed and held by the ink absorbing material 73, and then a part of the ink evaporates from the upper end opening of the collection container 72.

  Next, when the inkjet printer 12 is used alone as a portable printer, first, the plug 59 is pulled out from an outlet (power source) (not shown), and the ink supply device 13 is detached from the inkjet printer 12. As a result, the connection state between each ink supply side connection portion 28 and each ink supply connection member 55 is released.

  That is, when each ink supply connection member 55 is pulled out from each ink supply side connection portion 28, the ink supply side valve 41 is pressed against the lower surface of the supply upper flange 38 by the biasing force of the coil spring 40, and the ink supply side valve Each ink supply side connection 28 is closed by 41. At the same time, the ink supply valve 63 is pushed downward by the urging force of the coil spring 64, and both supply holes 61 are closed by the ink supply valve 63. Therefore, evaporation of the ink in each sub ink tank 27 to the outside through each ink supply side connection portion 28 is suppressed, and leakage of the ink in each supply ink tank 51 from the both supply holes 61 to the outside is suppressed. Is suppressed.

  Subsequently, when the ink collecting device 14 is detached from the ink jet printer 12, the connection state between the ink collecting side connecting portion 31 and the ink collecting connecting member 71 is released. That is, when the ink collection connection member 71 is pulled out from the ink collection side connection portion 31, the ink collection side valve 45 is pressed against the upper surface of the collection lower flange 44 by the urging force of the coil spring 46, and the ink collection side valve 45 The ink collection side connection part 31 is closed. At the same time, the ink recovery valve 80 is pushed upward by the urging force of the coil spring 81, and both recovery holes 78 are closed by the ink recovery valve 80. Therefore, leakage of the ink in the cap 29 to the outside through the ink collection side connection portion 31 is suppressed, and entry of foreign matters such as dust into the ink collection connection member 71 from both the collection holes 78 is suppressed. Is done.

  As described above, the ink jet printer 12 is supplied with the ink supply device 13 and the ink recovery device from the ink jet printer 12 as long as the rechargeable battery 36 is charged and each sub ink tank 27 is filled with ink. By detaching 14, it can be used alone as a small portable printer. In this case, as described above, when the rechargeable battery 36 is charged and the ink is supplied to each sub ink tank 27, the ink jet printer 12 is charged with the amount of power charged in the rechargeable battery 36 and each sub ink. This corresponds to the ink supply amount supplied into the tank 27.

  Therefore, the ink jet printer 12 is always in a state where ink is stored in each sub ink tank 27 by the amount of ink that can be ejected with the amount of power charged in the rechargeable battery 36. Therefore, when the amount of power charged in the rechargeable battery 36 becomes zero by performing printing, the ink jet printer 12 also reduces the amount of ink stored in each sub ink tank 27 to zero. As a result, in the ink jet printer 12, it is possible to avoid a situation in which ink remains in each sub ink tank 27 even though the power of the rechargeable battery 36 is lost, so that waste of ink can be suppressed. .

  When the ink jet printer 12 is used alone, the recording head 25 is cleaned by flushing that discharges each ink from the nozzles 26 into the cap 29 independently of printing.

The amount of electric power required for ejecting ink corresponding to the amount of ink supplied is configured. For this reason, when the ink jet printer 12 is used alone, when the power of the rechargeable battery 36 is used up by printing, the ink in each sub ink tank 27 can be used up. Accordingly, it is possible to avoid a situation in which ink remains in each sub ink tank 27 even though the power of the rechargeable battery 36 is exhausted, so that waste of ink can be suppressed.

  In addition, since the ink jet printer 12 does not have a mechanism for supplying ink to each sub ink tank 27 and a mechanism for charging the rechargeable battery 36 in the main body case 15, it can be made small and light. Portability when the rechargeable battery 36 is used alone as a power supply source can be improved. That is, the ink jet printer 12 can be a small portable printer having excellent portability.

  (2) In the ink jet printer 12, the control unit 82 measures the time during which the rechargeable battery 36 is charged, and drives the pressurizing pump 52 for a predetermined time based on the measured time. 27 is configured to adjust the amount of ink supplied to 27. For this reason, the amount of power charged in the rechargeable battery 36 can be reliably matched to the amount of power required for ejecting ink corresponding to the amount of ink supplied to each sub ink tank 27.

  (3) Since each ink stored in each supply ink tank 51 is supplied to each sub ink tank 27 when the ink supply connection member 55 is connected to the ink supply side connection portion 28, each supply ink Each ink stored in the tank 51 can be easily supplied to each sub ink tank 27.

  (4) By pressurizing the ink stored in the supply ink tank 51 by the pressurizing pump, the ink can be pressure-fed to the ink supply connecting member 55 side. Therefore, the ink stored in the supply ink tank 51 can be quickly supplied to the sub ink tank 27.

(5) When the charging connection terminal 85 is connected to the charging side connection terminal 83, the rechargeable battery 36 is charged by the charger 57, so that the rechargeable battery 36 can be efficiently charged.
(6) If the ink jet printer system 11 has one ink supply device 13 and one ink recovery device 14 each having a charging device, the ink jet printer 12 is charged, supplied with ink, and recovered with ink. Can be performed sequentially. For example, if the whole family of four wants to purchase the ink jet printer system 11, if one of the family purchases the ink jet printer system 11, the other three need only purchase the ink jet printer 12. Therefore, the user's economical burden can be reduced.

(7) Further, if the ink supply device 13 and the ink recovery device 14 having the charging device are configured to be able to charge, supply ink, and collect ink to the plurality of ink jet printers 12 at the same time. The convenience of the user when using the ink jet printer 12 can be improved by installing the ink supply device 13 and the ink recovery device 14 having these charging devices in stores in the town. That is, the user can easily charge the ink jet printer 12, supply ink, and collect ink from the ink jet printer 12 even when away from home.

When a negative determination is made in step S15, the control unit 82 executes the process of step S15 again. If the determination in step S15 is affirmative, the control unit 82 turns off the connection switch 90 (step S16) and stops charging the rechargeable battery 36. Thereafter, the control unit 82 ends the ink supply processing routine.

  When the rechargeable battery 36 is charged and the ink is supplied to the sub ink tank 27, the ink supply processing routine of this embodiment is executed, so that the amount of power charged in the rechargeable battery 36 is reduced to the sub ink. The amount of power required to eject ink corresponding to the amount of ink supplied to the tank 27 can be set.
