2. Description of the Related Art Conventionally, a technique for joining a liquid crystal display substrate and another circuit board using a pressure contact type connector in an electronic device including a liquid crystal display unit has been provided. For example, the configuration of Patent Document 1 discloses a configuration in which a pattern formed on a flexible printed circuit board and a transparent electrode of a liquid crystal display unit are electrically connected by a pressure contact type connector.
JP-A-11-52881

  By the way, the pressure contact type connector used for joining the liquid crystal display substrates as described above is generally configured to be sandwiched between two substrates arranged substantially in parallel as in Patent Document 1. That is, a configuration in which a terminal arranged at one end portion of the pressure contact type connector is pressed by a pattern portion of a liquid crystal display substrate and a terminal arranged at the other end portion is pressed by a pattern portion of another circuit board is common.

  However, in the case where the liquid crystal display substrate and the circuit substrate that is electrically connected to the liquid crystal display substrate cannot be arranged in parallel, or the demerit is caused by arranging them in parallel, the substrate surfaces of both substrates intersect (for example, orthogonal). It is desirable to arrange so that. However, when arranged in this way, the pressure contact type connector cannot be held between the two substrates, and the pattern portion on the substrate cannot be stably pressed by the terminals of the pressure contact type connector, and it becomes difficult to ensure the conduction between the two substrates.

  On the other hand, when the liquid crystal display substrate and the circuit board to be connected are arranged in an intersecting state as described above, a small intermediate substrate arranged in parallel with the liquid crystal display substrate is separately provided between the liquid crystal display substrate and the circuit substrate. A method of providing electrical connection between the liquid crystal display substrate and the circuit board by connecting the intermediate board and the circuit board is also conceivable. However, if the connection is made in two stages in this way, the number of parts increases, the cost increases, and the required installation space also increases.

  The present invention has been made based on the above circumstances, and even when the liquid crystal display substrate and the circuit board are arranged in the main body case so as to cross each other, the pressure contact type connector and both the boards are arranged. It is an object of the present invention to provide a configuration capable of appropriately achieving the conduction.

<Invention of Claim 1>
According to the first aspect of the present invention, when the liquid crystal display board and the circuit board are arranged in the main body case in the direction intersecting each other, both ends of the pressure contact type connector are pressed by the circuit board and the liquid crystal display board, respectively. Thus, the pressure contact type connector can be held by the guide portion.

<Invention of Claim 2>
According to invention of Claim 2, a liquid crystal display substrate and a circuit board can be efficiently arrange | positioned in the orthogonal direction. On the other hand, when the liquid crystal display substrate and the circuit board are arranged in an orthogonal state as described above, the pressure contact type connector cannot be sandwiched between the liquid crystal display substrate and the circuit board.

By utilizing this, it is possible to appropriately guide the respective end portions of the pressure contact type connector in a direction orthogonal to the respective substrates. In addition, since a curved wall having a curved wall surface facing the outer surface of the bent portion of the pressure contact connector is formed adjacent to the first guide wall and the second guide wall, the pressure contact connector is held by the guide portion. Can be guided smoothly, and the curved surface can be used to generate a pressing force at both ends.

<Invention of Claim 5>
According to the invention of claim 5, since the light emitting element for the backlight for the liquid crystal display substrate is arranged on the circuit board, it is not necessary to separately arrange the backlight substrate in parallel with the liquid crystal display substrate, and the number of components is reduced. Reduction and cost reduction can be effectively realized.

<Invention of Claim 6>
According to the invention of claim 6, since the light emitting element mounted on the circuit board is configured to irradiate light to the lateral side along the board surface of the liquid crystal display board, the circuit board arranged orthogonally is used. Thus, the liquid crystal display substrate can be irradiated with light in a compact and efficient manner.

That is, the one end side portion 31 is guided along the first wall surface 61A. The second guide wall has a second wall surface 62 </ b> A that faces the outer surface 32 </ b> B of the other end portion 32 of the press-contact connector 30 and is orthogonal to the substrate surface 10 </ b> A of the liquid crystal display substrate 10. The other end side portion 32 is guided along the second wall surface 62A.

Further, even in the case where they are arranged so as to cross each other, the pressure contact type connector 30 is guided by the guide portion 60 so that both end portions of the pressure contact type connector 30 are pressed by the circuit board 20 and the liquid crystal display substrate 10 respectively. Since it is held, both substrates can be appropriately conducted using the pressure contact type connector 30.

  Specifically, the liquid crystal display substrate 10 and the circuit substrate 20 are efficiently arranged in an orthogonal state. On the other hand, when the liquid crystal display substrate 10 and the circuit board 20 are arranged in an orthogonal state in this way, it becomes difficult to hold the pressure contact type connector 30 between the liquid crystal display substrate 10 and the circuit board 20, and therefore both ends of the pressure contact type connector are used. It becomes difficult to press the respective parts against the liquid crystal display substrate 10 and the circuit substrate 20 to achieve conduction.

And the circuit board 20 sandwich the one end portion 31 and the other guide portion and the liquid crystal display substrate 10 sandwich the other end portion 32. This is a preferred example in which the end can be stably pressed against the substrate.

  In the guide portion 60, a first guide wall 61 having a first wall surface 61 </ b> A that faces the outer surface of the one end portion 31 of the folded pressure contact connector 30 and is orthogonal to the substrate surface 20 </ b> A of the circuit board 20, and a pressure contact connector Since the second guide wall 62 having the second wall surface 62A facing the outer surface of the other end portion 32 of the liquid crystal display 30 and orthogonal to the substrate surface 10A of the liquid crystal display substrate 10 is formed, the bent pressure contact type connector is formed. The return force of 30 can be used to guide each end of the press-connecting connector 30 in a direction orthogonal to each board.

  In addition, a curved wall 63 having a curved wall surface 63A facing the outer surface of the bent portion 33 of the press contact connector 30 is formed adjacent to the first guide wall 61 and the second guide wall 62. 30 can be guided smoothly when the guide portion 60 is held, and a pressing force can be generated at both end portions by utilizing the curved surface.

  Since the light emitting element 22 for the backlight with respect to the liquid crystal display substrate 10 is arranged on the circuit board 20, it is not necessary to separately arrange the backlight substrate in parallel with the liquid crystal display substrate 10, thereby reducing the number of parts and the cost. It can be realized effectively.

  Since the light emitting element 22 mounted on the circuit board 20 is configured to irradiate light to the direction side along the substrate surface 20A of the circuit board 20, the liquid crystal display board 10 is used by using the circuit boards 20 arranged orthogonally.
