  • Fig. 3 shows an example of a liquid jet recording apparatus to which the present invention is applied.

  • a recording sheet 515 which is a recording material, is fed while being held at a position where it faces the discharge opening array 513 by rollers 516 and 517.
  • the recording head 507 when the recording head 507 is to be mounted on the carriage 501, the recording head 507, together with the ink tank 514, is first inserted into the mounting portion 501A in a state where the pressing pin 511 is retracted from the mounting portion 501A.

  • the above-described arrangement ensures highly accurate positioning of the recording head relative to the carriage.
  • the pushing force P applied to the recording head 507 when it is mounted on the mounting portion 501A of the carriage 501 is dispersed into three portions: a pressure P1 which connects the connectors with each other, and pressures P2 and P3 which bring the contact surfaces 507A and 507B into contact with the contact surfaces 506A and 506B, respectively.
  • these pressures P1, P2 and P3 may not be obtained adequately, e.g., pressures P2 and P3 may be sufficient whereas pressure P1 applied to the electrical connecting portions may be too little.
  • pressure P1 may be sufficient whereas pressures P2 and P3 may be too little.
  • pressures P1, P2 and P3 may be increased at the same time by increasing the force P. However, this requires a stronger structure and a larger amount of force to mount the recording head on and to remove it from the carriage, and thus reduces operability of the apparatus.

  • both the pressing force required for positioning the recording head and the pressing force required for electrical connection can be generated and uniformly distributed by one pressing force generating means.
  • the minimum pressing force can be effectively utilized, eliminating any need for an increase in the pressing force generated by the pressing force generating means. This leads to a reduction in deformation of the carriage caused by an increased pressing force and to the capability of use of a lightweight resin as the material for the associated components.
  • a connector on a body is made movable.
  • the connector on the body is fixed by a positioning means.
  • fixing of the body connector is released, and the body connector is thereby made movable relative to the body so as to achieve highly accurate positioning of the recording head.

More specifically, when the cartridge C is to be mounted on a mounting portion 2f of the carriage 2, the cartridge C is first located just above the mounting portion 2f, and then moved downward so as to insert the recording head 1 between a front end portion 2g and a rear end portion 2h of the mounting portion 2f, as shown in Fig. 9B.
  • This allows the contact surfaces 1a and 1b of the recording head to come into contact with the contact surfaces 2a and 2b, thereby horizontally positioning the recording head 1 relative to the carriage 2.

  • the connector 6 is mounted on the connector holder 40 with a backlash (a play) therebetween by means of a tension spring 41 which urges the connector 6 in the direction indicated by the arrow B.
  • Reference numerals 1e and 1f denote rough guides for guiding the recording head 1 when it is inserted into the carriage 2.
  • the cartridge C is removed from the carriage 2 in the following manner.
  • Fig. 9A shows a state where the recording head (cartridge C) is released from its positioned state
  • Fig. 9B shows a state where the recording head (cartridge C) is being removed from the carriage 2.
  • the lever 7, which will be described later, is operated and the connector holder 40 is thereby moved in the rightward direction, as shown in Fig. 9A, so as to release the recording head 1 from its fixed state.
  • the connector holder 40 is moved in the rightward direction, the recording head 1 abuts against the rough guides 1e and 1f and is thereby restricted from moving further to the right.
  • the body connector 6 is separated from the head connector 5, and at the same time the pressing pin 10 is separated from the recording head 1 and thereby releases the recording head 1 from its positioned state (as shown in Fig. 9A).
  • the connector 6 is weakly urged in the rightward direction (in the direction indicated by the arrow B) by the elastic force of the tension spring 41, and engagement shafts 6a, 6b and 6c of the body connector 6 are thereby fitted into engaging portions 40b, 40la and 40ma of engagement hole 40a and two engagement holes (40l and 40m) for positioning the connector 6.

  • the body connector 6 is roughly positioned as a consequence of the fitting of the engagement shaft 6a into the fitting portion 40b.
  • the connector holder 40 is moved rightwardly by a distance l , as shown in Fig. 10B (this movement of the connector holder 40 is achieved by the pivot of the lever 7, as will be described later). Movement of the connector holder 40 by this distance l allows the engagement shaft 6a to be separated from the fitting portion 40b. This results in releasing of the body connector 6 from its positioned state (it is to be noted that the body connector 6 is movable when it is in the state shown in Fig. 10A).
  • the body connector 6 is engaged with the head connector 5 more firmly than it is urged by the tension spring 41, so it is released from the connector holder 40, i.e., the connector 6 is disengaged from the connector holder 40.
  • the engagement shaft 6a is loosely fitted into the large diameter portion 40c with a gap g therebetween. This means that, while the body connector 6 is in engagement with the head connector 5, the body connector 6 is disengaged from the connector holder 40. Therefore, the cartridge C (the recording head 1) is positioned relative to the carriage 2 only by the pressing force of the pressing pin 10, which ensures accurate positioning of the recording head 1 relative to the carriage 2.
  • Fig. 10C shows a fitting state of the engagement shaft 6a into the engagement hole 40a which is obtained when the cartridge C (the recording head 1) is removed (released).
  • the lever 7, which is in its vertical position is pivoted counterclockwise and is thereby positioned in its horizontal position so as to move the connector holder 40 rightwardly.
  • the body connector 6 is engaged with the head connector 5 firmly, as the connector holder 40 moves rightwardly, a left edge L of the engagement hole 40a abuts against the engagement shaft 6a, and then pushes the engagement shaft 6a in the direction indicated by the arrow b (see Fig. 10C).
  • the body connector 6 is disengaged (released) from the head connector 5.
