  1A and 1B show a state in which a first main body 1 having a liquid crystal display body 3 and a second main body 2 having an operation unit are folded with the liquid crystal display body 3 facing upward.

As shown in FIGS. 1 a, b, c, and d, both main bodies 1 and 2 are connected by a pair of connecting rods 4 and 5.
These connecting rods 4 and 5 are covered on the sides by the main bodies 1 and 2.

  The guide plates 6, 7, 8, and 9 serving as covers are configured integrally with the main bodies 1 and 2, while forming a cantilever beam that is open at the top and bottom.

  That is, slits 10, 11, 12, and 13 are formed, and most of the connecting rods 4 and 5 are inserted into the slits 10, 11, 12, and 13, respectively.

  Since the liquid crystal display 3 is on the upper surface, confirmation of mail reception, confirmation of time, etc. can be performed.

  FIGS. 1c and 1d show a state in which the first main body 1 is slightly slid on the second main body 2, and the function keys 18 are exposed so that a considerable operation is possible.

  As shown in FIGS. 1b and d, the balls 16 and 17 provided in the connecting rods 4 and 5 roll in the guide grooves 14 and 15 provided in the guide plates 6 and 8, and stop in the state shown in FIG. 1d.

  Details will be described later.

Next, as shown in FIGS. 1e and f, the connecting rods 4 and 5 are stretched.
The connecting rods 4 and 5 are formed in a double cylindrical shape and are extendable.
The connecting rod has a stopper in the shortest length so that it does not easily stretch.
In addition, there is a stopper even in the case of the longest length so that it will not fall out.

  When the connecting rods 4 and 5 are fully extended from the state shown in FIGS. 1e and f, the main bodies 1 and 2 can be made straight as shown in FIGS. 2a, b and c.

  Then, by pressing the lever 20 provided on the back surface of the main body 2, the projecting pieces 21 and 22 are fitted into the concave portions of the main body 1.

  In this way, the main bodies 1 and 2 can be firmly coupled by operating the lever 20.

Since the entire operation unit of the main body 2 is exposed, all the functions of the mobile phone can be utilized.
Reference numeral 19 denotes a numeric keypad.

  When the main body 1 is rotated once in the state shown in FIGS. 1e and f and folded, the liquid crystal display body 3 can be accommodated and protected.

  The battery is housed on the main body 2 side, and power is supplied to the main body 1 by placing cables in the connecting rods 4 and 5. The battery may be provided on the main body 1 side.

  As with the power supply line, signals may be exchanged by placing cables in the connecting rods 4 and 5, but wirelessly because the connecting rods must be thickened.

  A transmission / reception unit is provided in each of the main bodies 1 and 2.

  If the wireless system is a Bluetooth system, it is possible to link with an optional product such as a headset. In addition, the Bluetooth method can be used even if there is an obstacle as long as the distance between devices is within 10 m, and the power consumption is small, so it is suitable for a mobile phone.

  Next, a specific configuration of each part will be described.

  First, the mechanism of the connecting portion between the connecting rods 4 and 5 and the main bodies 1 and 2 will be described.

  3a, 3b and 4 show the connecting rod 4 and the guide plate 7 as an example. The other parts have the same mechanism.

  The guide plate 7 is provided with guide grooves 7a (corresponding to 14 and 15 in FIGS. 1b and d). An insertion hole 7b is provided on the bottom surface of the guide groove 7a, and a small insertion hole 7c is provided on the side wall. On the other hand, the connecting rod 4 is provided with a disk body 4 a fixed to the connecting rod 4. A ball 4b (corresponding to 16 and 17 in FIGS. 1b and 1d) is movably inserted into the central hole of the disk body 4a.

  The connecting rod 4 is provided with a recess 4c into which a part of the ball 4b is inserted, and a spring 4d is housed therein to urge the ball 4b toward the guide plate 7 side. A plurality of balls 4e protrude from the periphery of the disk body 4a.

  As shown in FIG. 4, the ball 4e is also urged toward the side wall of the groove 7a of the guide plate 7 by the spring 4f.

  The connecting rod 4 is further provided with a passage 4 g through which a power cable 25 is passed and led to the main body 1. The main body 1 is formed with a slit through which the cable 25 passes.

  The main body 1 and the connecting rod 4 are in slidable contact with a disc body 4 h fixed to the connecting rod 4. Of course, a ball mechanism similar to that on the guide plate 7 side may be provided.

  When the connecting rod 4 is slid from the state of FIG. 3A, that is, the ball 4b moves in the guide groove 7a of the guide plate 7, and the ball 4b is fitted into the fitting hole 7b. By this mechanism, the main body 1 and the main body 2 are fixed to the states of FIGS. 1a and 1b, the states of FIGS. 1c and d, and the state of FIG.

  Further, as shown in FIG. 4, the guide plate 1 and the connecting rod 4 can be held at a constant angle by inserting the ball 4e into the fitting hole 7c. When the connecting rod 4 is rotated and different balls 4e are inserted into the fitting holes 7c, the guide plate 7 and the connecting rod 4 can be held at different angles.

  When the state shown in FIG. 1d is changed to the state shown in FIG. 2c through the state shown in FIG. 1f, the operation can be favorably performed by clicking the ball 4e and the insertion hole 7c.

  As shown in FIG. 5, the connecting rod 4 is fitted with double cylinders 4i and 4j so that the length can be freely adjusted. The protrusion 4m is inserted into the insertion holes 4k, 4l, and is configured to stop at the longest length and the shortest length.

  6A and 6B show the relationship between the lever 20 and the protrusions 21 and 22 and the recesses 26 and 27 into which the protrusions 21 and 22 are fitted.

  7A, 7B, and 7C show a state in which the power cord 25 has a margin in the main body 1 so that the connecting rod 4 is not pulled even if it moves.

  The specific mechanism is not limited to these, and various modifications are possible.

  For example, in FIG. 1, both ends of the connecting rods 4 and 5 are configured to slide with respect to the main bodies 1 and 2, but one end of the connecting rods 4 and 5 is configured to slide with respect to the main body. May be.

  Further, the relationship between the ball 4b and the insertion hole 7b in FIG. 3 may be reversed.

  That is, the ball 4b and the spring 4d are provided on the guide plate 7 side, and the insertion hole 7b is provided on the connecting rod 4 side.

  Similarly, the relationship between the ball 4e and the insertion hole 7c in FIG. 4 may be reversed. That is, the place of the ball 4e is set as the insertion hole 7c, and the ball 4e urged by the spring 4f is provided at the insertion hole 7c. This requires fewer balls 4e and springs 4f.

  By configuring as described above, the main body 1 and the main body 2 can be used with the liquid crystal display body 3 facing upward in a state where the main body 1 and the main body 2 are overlapped as shown in FIG. 1a.

  Further, the liquid crystal display 3 can be used face down.

  Further, as shown in FIG. 1 c, the main body 1 can be slightly slid with respect to the main body 2, and considerable operations can be performed by the function keys 18.

  Furthermore, as shown in FIG. 2, it can be used in a state of being straightened, and can be changed to various use states according to the user's preference.

  Since the power cable can be stored in the connecting rod, the appearance is not deteriorated.

  In addition, if the Bluetooth method is used for signal transmission and reception, it is possible to link with optional products such as headsets, etc. The Bluetooth method can be used even if there is an obstacle if the distance between devices is short, and the power consumption is small. Suitable for mobile phones.

  Moreover, since the connecting rod is covered with the guide plate, the connecting portion of the connecting rod is not damaged by the external pressure.

  Further, since the connecting rod slides on the guide groove of the guide plate by the ball, it is possible to prevent the main bodies from rubbing.

  Furthermore, since the click mechanism is added to the connection mechanism between the connection rod and the main body, the main bodies can be used at various angles.
