DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0031] The following is the description of an embodiment of the present invention as carried out on a Cellphone handset. However, the sliding mechanism according to the present invention can be carried out on personal digital assistants (PDA) such as ZAURUS (trade mark), electric calculators, pocket computers, handheld gaming devices, ash trays, lid for case, and the like. [0032] The drawings describe in detail a mode of carrying out the present invention with reference to FIGS. 1 9. The indicative symbol 2 in FIGS. 1 to 3 in particular represents for example the transmitting part of a Cellphone handset 1 that constitutes the first case. On the surface of this first case 2, a microphone part 2 a and a keyboard part 2 b are provided, and superposed and slidably fixed in the longitudinal direction on the first case 2 is, for example, the receiving part of the Cellphone handset 1 constituting the second case 3. On the surface of this second case 3, a speaker part 3 a and a display part 3 b are provided. Incidentally, the indicative symbol 4 represents an antenna. This antenna 4, fixed on the first case 2, can also be fixed on the second case 3. [0033] As shown in FIG. 4, particularly on both sides of the upper surface of the first case 2, racks 2 c and 2 c are provided, and grooves 2 d and 2 d engaging therewith are also provided. On both sides of the bottom of the second case 3, sliding parts 3 c and 3 c are provided in roughly C section in sliding contact with the racks 2 c and 2 c, and these sliding parts 3 c and 3 c are engaged slidably with the engaging grooves 2 d and 2 d. [0034] Then, the indicative symbol 7 represents a sliding module. This sliding module 7, as FIG. 5 shows particularly, are fixed on the back of the upper cover 2 e of the first case 2, and the fixing pin 9 provided so as to protrude from the slider 8 slidably housed in the sliding case 5 that constitutes the sliding module 7 protrudes upwards through a guiding long hole 28 provided in the upper cover 2 e, and this fixing pin 9 is fixed on the bottom cover 3 d of the second case 3 through a fixing screw 12. [0035] And the method of fixing the sliding module 7 to the upper cover 2 e is, as FIG. 5 shows in particular, to form a catching part 2 g on the back of the upper cover 2 e, to provide locking concaves 2 h and 2 h on the front part and the rear part of this catching part 2 f, and to insert fit both ends of the sliding module 7 received by the catching part 2 g in the locking concaves 2 h and 2 h. [0036] The construction of this sliding module 7 is shown in particular in FIGS. 6 to 9. According to the drawings, the indicative symbol 10 represents a locking plate, and locking slips 10 b, 10 b . . . are provided on a plurality of rising slips 10 a, 10 a . . . rising at fixed intervals from the surrounding members, and locking convexes 10 c and 10 d are provided in an orthogonal direction to the locking plate on both ends in its longitudinal direction. [0037] Incidentally, although the figures show an embodiment with only one sliding module 7 mentioned above, two or more of them can be used. [0038] The indicative symbol 11 represents a sliding cover. A plurality of locking holes 11 b, 11 b . . . engaging with the locking slips 10 b, 10 b . . . are provided on the hanging slips provided around it, and the locking plate 10 is covered with the sliding cover 11 and each locking slip 10 b is engaged with each locking hole 11 b to build a solid structure. [0039] In the sliding case 5 constituted by the locking plate 10 and the sliding cover 11, a plate-shaped slider 8 is fixed slidably, and this slider 8 include convexes 8 a and 8 b formed at the center thereof and in the direction orthogonal to the slider 8 on both ends in the longitudinal direction. This slider 8 is also fixed with pressurized contact by a leaf spring 14 between the locking plate 10 and the sliding cover 11 constituting the sliding case 5. And as shown in FIG. 8 in particular, the locking convexes 10 c and 10 d of the locking plate 10 and the convexes 8 a and 8 b of the slider 8 constitute the locking means 15. [0040] As described above, a fixing pin 9 is fixed to this slider 8 through the leaf spring 14. This fixing pin 9 pierces through a guiding long hole 11 c provided on the sliding cover 11 and another guiding long hole 2 f provided on the upper cover 2 e of the first case 2 to thrust out. And the fixing pin 9 is fixed, as described above, by a fixing screw 12 on the bottom cover 3 d on the side of the second case 3. In this way, the engaging grooves 2 d and 2 d, the sliding parts 3 c and 3 c, and the sliding module 7 constitute the sliding mechanism 6. [0041] And now the functions of the sliding mechanism according to the present invention will be described below. When the first case 2 and the second case 3 are in a closed position of both of them lying one on the other, the convex 8 a provided on one end of the slider 8 in the sliding case 5 is engaged with the locking convex 10 c provided at one end of the locking plate 10, and both are in a locked state. [0042] Therefore, unless an outside force is applied, the first case 2 and the second case 3, in other words the transmitting part and the receiving part do not slide naturally. When the object of carrying out the present invention is a Cellphone handset as shown in the figure, the first case 2 constituting the transmitting part and the second case 3 constituting the receiving part are in this state constituted in a compact form, can be easily stored and held, present no risk of the operating keys being pressed while the whole product is carried, and in addition enables anyone to view the image and information displayed on the display device 3 b provided on the second case 3 side in this state. And due to the engagement of the sliding parts 3 c and 3 c with the engaging grooves 2 d and 2 d, the first case 2 and the second case 3 are inseparably engaged mutually by this engaging means other than the sliding module 7. [0043] And when the first case 2 and the second case 3 are made to slide relatively further in the longitudinal direction, the convex 8 a of the slider 8 is unlocked from the locking convex 10 c of the locking plate 10, and the slider 8 in the sliding case 5 slides in the sliding case 5 by pressurized contact due to the elasticity of the leaf spring 14. Therefore, the first case 2 and the second case 3 can be made to slide mutually to stop at any desired position. [0044] When the first case 2 and the second case 3 are made to slide further relatively, the convex 8 b provided at another end of the slider 8 engages with the locking convex 10 d provided at another end of the locking plate 10, and at the same time a side of the fixing pin 9 enters into contact with an end of the guiding long hole 11 c provided on the sliding cover 11, and here again the first case 2 and the second case 3 are mutually locked. [0045] In this state, the keyboard part 2 b of the transmitting part becomes exposed, and the whole set is ready to be used as a Cellphone handset. Or, even if the first case 2 and the second case 3 are not made to slide completely, sometimes the whole set is ready to be used. Moreover, even if an outside force is applied to bend the second case 3 to the back at this state, the first case and the second case are mutually engaged by the sliding parts 3 c and 3 c engaged with the engaging groove 2 d and 2 d, and therefore the load in this bending direction does not weigh only on the sliding case 5. [0046] Then, when the first case and the second case are made to slide each other and then are led to return to the superposed position, the convex 8 b of the slider 8 is again disengaged from the locking convex 10 d of the locking plate 10, and the first case 2 and the second case 3 slide stoppably at any desired position, and the convex 8 a of the slider 8 and the convex 10 c of the locking plate 10 return to their engaging position to be locked here. Then, the side of the fixing pin 9 gets into contact with an end of the guiding long hole 11 c. However, it is possible to choose steps to ensure that an end of the slider 8 get into contact with an end of the sliding case 5 as a discretionary stopper measure at the position where the slider 8 is locked. And the guiding long hole 11 c provided on the sliding cover 11 side may be provided on the locking plate 10 side. [0047] FIG. 10 shows another embodiment of the locking means, and the locking means 20 in this embodiment derives its locking action from the engagement of the concaves 21 a provided on both sides of both ends of the slider 21 with the convexes 22 a provided on the sides of the locking plate 22. [0048] In each of the embodiments described above, however, the convexes and concaves provided in the locking plate may be provided on the sliding cover side, and the leaf spring 13 may intervene between the locking plate and the slider. [0049] FIG. 11 shows another embodiment of the sliding mechanism, and shows a case of reversing the position of the engaging grooves and the sliding parts provided in the first case 23 and the second case 24 from that of the embodiment 1, wherein the engaging grooves 25 are provided in the second case 24 and the sliding parts 26 engaged with these engaging grooves 25 are provided on the first case 23 side. [0050] The object of the present invention can be achieved by such a way of carrying out. [0051] FIG. 12 is shows still another embodiment of the sliding mechanism, wherein the engaging member 31 in which the engaging grooves 30 and 30 are provided and the sliding members 33 and 33 in each of which a sliding part 32 is provided are made of separate materials from the first case 34 and the second case 35. [0052] The object of the present invention can be achieved by such a way of carrying out. [0053] The present invention can be carried out for slidably connecting mutually the first case and the second case of a Cellphone handset constituting a type of mobile terminal, other personal digital assistants (PDA) such as ZAURUS (trade mark), electronic calculators, pocket computers, handheld gaming devices, ash trays, lids for case and the like. [0054] The foregoing invention has been described in terms of preferred embodiments. However, those skilled, in the art will recognize that many variations of such embodiments exist. Such variations are intended to be within the scope of the present invention and the appended claims.
