The ink jet printer is provided with a carriage having a recording head mounted on the lower surface and reciprocating in the main scanning direction. An ink cartridge is loaded on the carriage, and a small substrate is provided as an electronic substrate that detects information such as the remaining amount of ink in the ink cartridge and transmits the detected information to the main substrate in the printer body.

  In this case, unless the ink cartridge is correctly and securely loaded into the carriage, accurate information cannot be transmitted to the small substrate. Therefore, as shown in Patent Document 1, a positioning portion is provided in the ink cartridge, or as shown in Patent Document 2.

In this case, since the mounting position of the small board is required to be constant, the size of the receiving recess formed on the carriage side is set to be relatively strict. May be scraped by a part of the receiving recess or the terminal of the connector to cause a contact failure. In addition, since the small board was inserted so as to be inserted, it is difficult to determine whether or not it was set at the correct position. At the time of insertion, the small substrate may be deformed and damaged.

FIG. 6 is a longitudinal side view showing the periphery of the small substrate installation site in an enlarged manner, and FIG. 7 is a plan view of the carriage shown by cutting the periphery of the small substrate installation site. 8 is a cross-sectional view taken along the line AA in FIG. 7, and FIG. 9 is a perspective view showing two types of small substrates having different shapes of engaging projections.

  The electronic substrate positioning apparatus 1 according to the present invention engages with an engaging convex portion 32 provided by extending and forming a part of a lower side of a small substrate 30 as an electronic substrate, and an engaging convex portion 32. A receiving recess 33 for receiving the small substrate 30 in a relatively permissive state without strict alignment is provided. As shown in FIG. 9 (a), two engagement convex portions 32 are provided, both of which have different width dimensions and are arranged asymmetrically in the right and left, so that incorrect mounting is possible with the front and back being mistaken. It has a prevented structure.

  The receiving recess 33 is formed so that the dimension in the depth direction is considerably larger than the thickness of the small substrate 30 so that the small substrate 30 can be accommodated with a margin. For example, four pressure connectors 34 are disposed on the inner surface of the receiving recess 33 in correspondence with the number of ink cartridges C provided for four colors. Further, at the bottom of the receiving recess 33, the small substrate 30 is positioned in the width direction by engaging with the engaging convex portion 32, and the lower side of the small substrate 30 where the engaging convex portion 32 is not formed. Engagement ribs 36 for positioning the small substrate 30 in the height direction by abutting on the small substrate 30 are provided.

  That is, two engagement ribs 36 are provided, and the inner side surface of the upper portion of the engagement rib 36 is engaged with the outer sides of the left and right engagement projections 32 provided on the small substrate 30. Thus, the small substrate 30 is positioned in the width direction, and the upper end surface of the engagement rib 36 is brought into contact with the lower side 35 of the outer small substrate 30 in the engagement projection 32 where the engagement projection 32 is not formed. Thus, the small substrate 30 is positioned in the height direction.

  The receiving recess 33 is provided with a pressing means for pressing the set small board 30 to the pressing connector 34. In this embodiment, a spacer 31 is provided as an example of the pressing means. The spacer 31 has a role of pressing the surface of the small substrate 30 set in the receiving recess 33 and pressing the contact 38 provided on the back surface of the small substrate 30 against the press contact terminal 39 of the press contact connector 34. Yes. As the spacer 31, a synthetic resin material having appropriate elastic force and rigidity can be used as an example.

  The spacer 37 is an unevenly shaped product having a substantially rectangular shape when viewed from the front, and a pressing rib 40 extending in the vertical direction is press-contacted to the inner surface of the spacer 31 at a position substantially coincident with the center of the press-connecting connector 34. Four are formed corresponding to the number of connectors 34. Further, four pressing ridges 41 extending in the vertical direction are formed on the inner wall surface on the front side of the receiving recess 33 at a position substantially coincident with the center of the press contact connector 34 corresponding to the number of press contact connectors 34. .

  The pressing ribs 40 and the pressing ridges 41 are provided in order to always obtain a strong pressing state between the pressing connector 34 and the small board 30 without depending on the bending deformation of the spacer 31 or the like. Further, the upper portion of the back surface of the spacer 31 has a right triangle shape in a side view, and is provided with a pushing inclined rib 42 that acts like a wedge. The push-in inclined rib 42 has a role of preventing an increase in a pressing force of the small board 30 against the press-connecting connector 34 and an accidental drop and displacement of the small board 30.

  Next, the electronic substrate positioning method of the present invention performed using the electronic substrate positioning apparatus 1 having such a configuration will be described. The electronic substrate positioning method of the present invention is used when the small substrate 30 as the electronic substrate is mounted in the receiving recess 33. The electronic substrate positioning method is executed in two steps: a first step of dropping the small substrate 30 into the receiving recess 33 and a second step of pressing the dropped small substrate 30 against the pressure contact connector 34.

  The first step is executed by dropping the small substrate 30 into the receiving recess 33 relatively without any particular strict alignment. Then, the dropped small substrate 30 is set in the receiving recess 33 in a state where the positioning is performed in the width direction and the height direction by the engaging action of the engaging protrusion 32 and the engaging rib 36. Further, the erroneous mounting of the small substrate 30 with the wrong side is prevented by the erroneous mounting preventing structure of the engaging convex portion 32 and the engaging rib 36.

  The second step is executed by inserting the spacer 31 into the remaining space formed outside the spacer 31 in the receiving recess 33. That is, when the spacer 31 is inserted into the remaining space, the spacer 31 presses the surface of the small substrate 30 via the pressing rib 40. Further, the spacer 31 also receives a pressing force from the inner wall surface on the front surface side of the receiving recess 33 by abutting against the pressing ridge 41, so that the small substrate 30 moves to the back side by these pressing forces, and the small substrate 30 The contact 38 on the back surface comes into contact with the press contact terminal 39 of the press contact connector 34, and an electrically conductive state is formed between the small substrate 30 and the press contact connector 34.
