Problems to be solved by the invention

[0003] However, in the above-described mobile phone, the slide cover is simply attached to the housing (equipment main body) so that it can be opened and closed. Therefore, the opening / closing operation can be performed with one hand. Usually difficult to do, you have to do it with both hands. However, it is often desirable to provide a structure that can easily open and close the slide cover with one hand, even if you want to operate it with only one hand, such as when receiving a call, when you receive a call! Ru

[0004] In general, a portable product needs to be carried and carried, and therefore it is desired to be small and thin. Therefore, as described above, it is possible to provide a slide cover moving mechanism, for example, a slide unit, which enables the portable product itself to be reduced in size and thinned by simply making it possible to easily open and close the slide cover with one hand. It is desired.

[0005] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a portable product provided with a slide cover, in particular, a portable product in which a slide cover can be easily opened and closed. The present invention is to provide a slide unit that can be suitably used for portable products and that enables the portable product itself to be reduced in size and thickness.

Means for solving the problem

[0006] The slide unit of the present invention includes a fixed plate, a movable plate slidably attached to the fixed plate, and a linear or thin plate attached between the fixed plate and the movable plate. And an elastic member. The elastic member is formed into a corrugated shape, and the movable plate moves so that the attachment portion of the elastic member to the movable plate approaches the attachment portion of the elastic member to the fixed plate. While elastically deforming, the attachment portion of the elastic member to the movable plate passes through the reversal point of the elastic member to return elastically, and urges the movable plate in the moving direction.

[0007] According to this slide unit, since it is basically composed of a fixed plate, a movable plate, and an elastic member, the overall structure is simple, and the unit itself can be made smaller and thinner. It is also possible to reduce the size and thickness of products using this unit. In addition, the movable plate is configured to be urged in the moving direction by the inertial restoring force of the elastic member by passing the reversal point of the elastic member. Therefore, the movable plate can be easily moved without requiring a complicated mechanism. It is possible to move.

[0008] In the slide unit, it is preferable that the elastic member has a loop portion wound at least once around a crest or trough in the corrugation.

In this way, the elastic member has the loop portion at the peak or valley of the corrugation that becomes wider or narrower due to inertial deformation and elastic return, so that the elastic member can be easily expanded and contracted. , Its durability will be high.

[0009] Further, in the slide unit, the elastic member also has two spring material forces, and these spring materials are respectively disposed on both sides of the center line along the moving direction of the movable plate. It is preferable.

In this way, it is possible to arrange other components between the spring members, and therefore it is possible to add functions without impairing the size and thickness of the slide unit.

[0010] Further, the slide unit is formed on one of the fixed plate and the movable plate. The movable plate is slidable with respect to the fixed plate by guiding the engaging plate formed on the other inside the groove-shaped guide groove. Preferably, the engaging plate is formed with a bulging portion that bulges due to its surface force and contacts the inner wall surface of the guide groove.

In this way, when the engaging plate relatively moves in the guide groove, the bulging portion provided in the engaging plate is in contact with the inner wall surface of the guide groove. Therefore, the movable plate slides smoothly with respect to the fixed plate.

The fixed plate of the slide unit is attached to one of the outer surface of the device body and the inner surface of the slide cover, and the movable plate of the slide unit is attached to the other of the outer surface of the device body and the inner surface of the slide cover. It is done.

[0012] According to this portable product, since the slide unit is provided between the outer surface of the device main body and the inner surface of the slide cover, as described above, the slide unit is made smaller and thinner.

The portable product itself is also made smaller and thinner. Further, as described above, since the slide unit can easily move the movable plate without requiring a complicated mechanism, the portable product including the slide unit is particularly slid. The cover can be opened and closed easily.

The invention's effect

[0013] In the slide unit of the present invention, the unit itself can be reduced in size and thickness, so that a product using the slide unit can be reduced in size and thickness. Also, by passing the reversal point of the elastic member, the movable plate is biased in the moving direction of the movable plate by the inertial restoring force of this elastic member! /, Thus requiring a complicated mechanism The movable plate can be easily moved without any trouble. Therefore, in products using this slide unit, for example, by attaching a moving member such as a slide cover to the movable plate, this moving member can be easily moved with one hand, thus improving its operability. can do. In the portable product of the present invention, as described above, the portable product itself can be made smaller and thinner by making the slide unit smaller and thinner.

BEST MODE FOR CARRYING OUT THE INVENTION

[0017] The present invention is described in detail below.

1 and 2 show an example of a mobile phone as a portable product equipped with the slide unit of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a diagram showing an embodiment. The mobile phone 1 also functions as a device main body 2, a slide cover 3 attached to the device main body 2, and a slide unit 20 provided between the device main body 2 and the slide cover 3.

[0018] The device body 2 has a substantially rectangular parallelepiped housing shape, has an antenna 4 on the upper end surface, and has a reception unit 5, a display unit 6, a key operation unit 7, and a transmission unit 8 on the front surface (outer surface). In order from the top to the bottom. A fixed plate 21 of the slide unit 20 is attached to the front surface (outer surface) of the device main body 2 below the transmitter section 8.

[0019] The slide cover 3 is made of grease formed and arranged so as to cover at least a part of the key operation unit 7 and the like of the device body 2, and includes a cover plate 3a covering the key operation unit 7 and the like, and a cover plate 3a It consists of side plates 3b formed on both sides. A movable plate 22 of a slide unit 20 is attached to the slide cover 3 on the inner surface of the cover plate 3a. Under such a configuration, the slide cover 1 is attached to the device body 2 via the slide unit 20.

The slide unit 20 is an embodiment of the slide unit of the present invention. As shown in FIG. 3A, the fixed plate 21 and the movable plate 22 slidably attached to the fixed plate 21 are provided. And an elastic member 23 composed of a pair of spring members 23a attached between the fixed plate 21 and the movable plate 22. The fixing plate 21 is attached to the front surface (outer surface) of the device body 2 as described above. The fixing plate body 24 is formed by bending both ends of the plate material substantially at right angles, and a pair of thin plates 24. It also serves as a force with the pair of panel fixing portions 25 formed inside the plate portion 24a.

[0021] The fixing plate body 24 is formed with a plurality of holes 24b for screwing, and screws (not shown) are inserted into the holes 24b. The fixed plate 21 is fixed to the device body 2 as described above by screwing the inserted screw into a screw hole (not shown) formed in the front surface (outer surface) of the device body 2.

As shown in FIG. 3B, the panel fixing portion 25 is partially bent so that the tip side is lifted to the movable plate 22 side. As shown in FIG. 3A, a mounting pin 25a for attaching the spring material 23a is attached to the lifted tip portion! One end portion (attachment portion) 23b of a spring material 23a is attached to the attachment pin 25a.

[0022] On the outer side of the thin plate portion 24a of the fixed plate main body 24, the end is bent upward, and further on the outer side. As a result, the rail 24c is formed. A stopper pin 26 is attached to one end of these rails 24c, that is, the end opposite to the tip of the thin plate portion 24a (the upper end side of the mobile phone 1). A stopper 24d is formed at the distal end of the thin plate portion 24a by raising the thin plate portion 24a toward the movable plate 22 side.

[0023] The movable plate 22 has a shape in which both ends of a plate member in which a plurality of screw fastening holes 22a are formed are bent at a substantially right angle. By screwing into a screw hole (not shown) formed on the inner surface of the force bar 3, the force bar 3 is attached to the inner surface of the slide cover 3 as described above. A plurality of engaging portions 27 that are engaged with the rail 24c in a state of sandwiching the rail 24c are formed on the outer side of the movable plate 22 by hemming bending. With such a configuration, the movable plate 22 can smoothly move in the length direction of the rail 24c by the engagement portion 27 being guided by the rail 24c of the fixed plate 21. In particular, since the engaging portion 27 is formed with a hemming bending force, it is guided to the rail 24c without rattling.

[0024] However, since the movable plate 22 has the stopper pin 26 attached to one side of the fixed plate 21 and the stopper 24d formed on the other side as described above, the stopper pin 26 and the stopper 24d are formed. You can only move between and / or! Therefore, since the movable plate 22 is prevented from being detached from the fixed plate 21, the slide cover 3 to which the movable plate 22 is attached is set so as not to be detached from the device body 2 to which the fixed plate 21 is attached. Move only the stroke that has been moved.

[0025] Mounting pins 28 are attached to the movable plate 22 on both sides, that is, on portions where the engaging portions 27 are formed. The other end portion (attachment portion) 23c of the spring material 23a is attached to the attachment pin 28. The mounting pin 28 on the movable plate 22 side is mounted outside the mounting pin 25a on the fixed plate 21 side. Therefore, when the movable plate 22 moves relative to the fixed plate 21, the mounting pin 25a does not interfere with the mounting pin 28.

[0026] The spring member 23a constituting the elastic member 23 is made of a metal such as stainless steel or high-tensile steel, or is made of a synthetic resin or the like. In this embodiment, a metal wire is formed into a corrugated shape. Is used. Although there is no particular limitation on the shape of the waveform, in this embodiment, a W shape is used in plan view as shown in FIG. 3A. That is, this embodiment The spring material 23a of the state is formed by forming two ridges and one trough on one side, and conversely forming one ridge and two troughs on the other side. . In particular, in the present embodiment, a loop portion 29 formed by winding a wire around the ridge (or valley) located at the center is formed. As will be described later, the loop portion 29 is a degree to which the peak portion (or valley portion) of the central portion becomes wider or narrower when the spring material 23a elastically deforms and returns elastically as the movable plate 22 moves. Therefore, by winding the wire around here, the spring material 23a can be easily expanded and contracted, and the durability of the spring material 23a is enhanced.

As described above, one end 23 b of the spring material 23 a is attached to the mounting pin 25 a of the fixed plate 21, and the other end 23 c is attached to the mounting pin 28 of the movable plate 22. The end portion (one end portion 23b or the other end portion 23c) attached to the mounting pin 25a (28) is formed by winding the wire rod once (or a plurality of times) in the same manner as the loop portion 29, and the mounting pin 25a ( It can be pivotally attached to 28). Therefore, since both end portions of the spring material 23a can be rotated with respect to the mounting pins 25a (28), the spring material 23a itself can also be rotated with respect to the mounting pins 25a and 28.

That is, when the movable plate 22 is moved to the state shown in FIG. 4 when the movable plate 22 is moved, the spring material 23a has the other end 23c side force attached to the mounting pin 28 of the movable plate 22. The outside of the one end portion 23b is rotated around the one end portion 23b attached to the mounting pin 25a of the fixing plate 21. Looking at this movement relatively, in other words, one end 23b side force attached to the mounting pin 25a of the fixed plate 21 and the other end 23c attached to the mounting pin 28 of the movable plate 22 Rotate inside end 23c. When moved from the state shown in FIG. 4 to the state shown in FIG. 3A, the other end 23c side on the movable plate 22 side rotates in the opposite direction.

[0029] At this time, as the movable plate 22 moves, the distance between the one end 23b and the other end 23c of the spring member 23a (the distance between the mounting pin 25a and the mounting pin 28) changes. The spring material 23a expands and contracts according to the amount of change. That is, when the movable plate 22 is moved from the state shown in FIG. 3A to the state shown in FIG. 4, the spring member 23a is displaced as shown in FIG. Fig. 5 schematically shows the relative movement (displacement) of the spring material 23a. The other end 23b attached to the mounting pin 25a of the fixed plate 21 is the moving side, and the movable plate 22 The one end 23c attached to the mounting pin 28 is the fixed side. The curve on the right side of Fig. 5 shows the spring material 23a and The change in the Y direction of the load applied to the mounting pin 25a by the spring material 23a as the mounting pin 25a moves is shown.

[0030] Here, the operation of the spring member 23a will be described. First, in the state shown in FIG. 3A, the spring member 23a is W-shaped as shown by a solid line a in FIG. In this state, the panel member 23a is biased in the direction of expanding the waveform by the elastic return force, that is, in the direction of separating the mounting pin 25a relative to the mounting pin 28. In this state, as shown in FIG. 3A, since the movable plate 22 is in contact with the stopper 24d, it is not moved further to the stopper 24d side.

[0031] In FIG. 5, the direction in which the mounting pin 25a moves relative to the mounting pin 28 (moving direction of the movable plate 22) is the Y direction, and the direction orthogonal to the Y direction is the X direction. In the state shown in FIG. 3A, the load (biasing force) applied to the mounting pin 25a in the Y direction by the spring material 23a is G1, as shown in FIG. Therefore, in order to move the mounting pin 25a relative to the mounting pin 28, it is necessary to relatively apply a force exceeding G1 to the mounting pin 25a. That is, by applying a force exceeding G1 to the movable plate 22, the movable plate 22 moves against the urging force of the spring material 23a. Actually, since two spring members 23a are provided between the fixed plate 21 and the movable plate 22, in order to move the movable plate 22, a force twice as large as G1 is required. However, for the sake of simplifying the explanation with respect to Fig. 5, we will consider one non-metallic material 23a as described above.

[0032] When a force exceeding G1 is relatively applied to the mounting pin 25a, the one end 23b of the spring member 23a approaches the other end 23c. Then, as the distance between them becomes shorter, the panel material 23a is compressed and elastically deformed. Then, as shown by a broken line b in FIG. 5, when one end 23b of the spring material 23a comes closest to the other end 23c, the spring material 23a moves the movable plate 22 relative to the fixed plate 21, that is, Y Force (G1) biased in the direction becomes zero. This position is the reversal point at which the spring material 23a is reversed. In this way, when one end 23b of the spring material 23a is brought closer to the other end 23c, G1 gradually decreases, so that the movable plate 22 can be moved easily, that is, smoothly. I understand.

[0033] When the force is further applied to the mounting pin 25a, one end 23b (relatively the other end 23c) of the spring member 23a passes through the reversal point, so that the spring member 23a is attached. Pin 25a Causes elastic return in the same direction as the force applied to. The movable plate 22 is biased in the moving direction by the spring material 23a. Therefore, the movable plate 22 is automatically moved by the urging force of the spring material 23a without applying a force toward the movable plate 22 forward in the moving direction. When such movement proceeds, the movable plate 22 comes into contact with the stopper pin 26 as shown in FIG. 4, and the movement of the movable plate 22 stops. At this time, the spring material 23a is in a state indicated by a broken line c in FIG. 5, and a load (biasing force) in the Y direction indicated by G2 is applied to the mounting pin 25a by the spring material 23a. Since G2 is a force in the opposite direction to G1, the spring member 23a indicated by the broken line b in FIG. 5 urges the movable plate 22 in the direction opposite to the state indicated by the solid line a.

[0034] When the moving distance L of the mounting pin 25a in the Y direction is longer than the distance W between the mounting pin 25a and the mounting pin 28 in the X direction shown in FIG. 5, the loop portion 29 is formed. The angle θ 1 at the valley is increased. Therefore, if the spring material 23a is designed so that the difference (θ 1 Θ 2) between the angle θ 1 and the angle Θ 2 at the inversion point indicated by the broken line b in FIG. The life of the spring material 23a can be extended. The lengths of the sides 11, 12, 13, and 14 constituting the spring member 23a are determined according to the required moving distance L (stroke) and loads G1 and G2. The inversion point can be adjusted by appropriately changing the lengths of the sides 11, 12, 13, and 14.

[0035] For comparison, FIG. 6 shows a case where a generally L-shaped spring material 30 is used as a spring material. The curve on the right side of FIG. 6 shows the change in the magnitude in the Y direction of the load applied to the mounting pin by the spring material 30 as the spring material 30 and the mounting pin shown on the left side of the figure move. Even in the spring material 30 shown in FIG. 6, the smaller the difference (Θ 3 Θ 4) between the angle Θ 3 in the state indicated by the solid line d and the angle Θ 4 at the reversal point indicated by the broken line e, is smaller. Durability is increased and the life of the spring material 30 is extended.

The spring material 30 shown in FIG. 6 has a larger Θ 3 than the spring material 23a shown in FIG. Therefore, a force that bends the spring material 30 in the loop portion 31 is greatly applied until the reversal point is reached, so that the durability of the loop portion 31 is deteriorated. Since the angle difference (0 3-0 4) is larger than that of the spring material 23a shown in FIG. Therefore, it can be seen that the spring material 23a of the present embodiment shown in FIG. 5 is particularly excellent in durability as compared with a general spring material. [0036] In the mobile phone 1 having the slide unit 20 having such a configuration force, the slide cover 3 is opened as shown in Fig. 1 in the state of use, and accordingly, the transmitter 8 and the key operation unit 7 is exposed without being covered by the slide cover 3. In this state, as shown in FIG. 3A, the slide unit 20 is in a state where the movable plate 22 biased by the spring material 23a is in contact with the stopper 24d side.

[0037] To end use and close the slide cover 3, for example, with the mobile phone 1 held in one hand, slide the slide cover 3 toward the antenna 4 with the thumb of the hand. Then, as the slide cover 3 moves, the movable plate 22 moves. At this time, in the initial stage of movement, the spring member 23a is elastically deformed as described above. In particular, when the attachment portion of the spring member 23a to the movable plate 22, that is, the other end portion 23c of the spring member 23a passes through the reversal point, the spring member 23a has been subjected to elastic deformation until then. It turns around and causes elastic recovery. Thereafter, the movable plate 22 easily moves due to the urging force generated by the elastic restoring force of the spring member 23a, and moves until it comes into contact with the stopper pin 26 as shown in FIG. 3B. In this way, the slide cover 3 also slides smoothly, and closes in a state of covering the transmission section 8 and the key operation section 7 as shown in FIG.

[0038] After the slide cover 3 is closed in this manner, when the slide cover 3 is used again, the slide cover 3 is slid to the side opposite to the antenna 4 with a thumb or the like. Then, in the slide unit 20, the movable plate 22 moves in the opposite direction to the previous one, and again moves until the movable plate 22 contacts the stopper 24d as shown in FIG. 3A. As described above, the slide cover 3 is opened as shown in FIG. 1, and the transmitter section 8 and the key operation section 7 are exposed.

[0039] Since the slide unit 20 in such a mobile phone 1 is composed of the fixed plate 21, the movable plate 22, and the elastic member 23 composed of a pair of spring members 23a, the entire unit has a simple configuration. It is smaller and thinner. Therefore, the mobile phone 1 using the slide unit 20 can be reduced in size and thickness.

Further, since the movable plate 22 is configured to be urged in the moving direction of the movable plate 22 by the elastic restoring force of the elastic member 23 by passing the reversal point of the elastic member 23, a complicated mechanism is required. The movable plate 22 can be easily moved without any trouble. Therefore, in the mobile phone 1 using the slide unit 20, the slide cover 3 is attached to the movable plate 22. Therefore, the slide cover 3 can be easily moved with one hand, and therefore the operability can be improved.

[0040] Further, since the loop portion 29 is formed at the peak (valley) in the waveform of the spring material 23a, the panel material 23a can be easily elastically deformed and elastically restored, and can be easily expanded and contracted. 2 3a durability can be increased.

Further, since the elastic member 23 is formed by the two spring members 23a, another component, such as a flexible substrate, can be disposed between the spring members 23a and 23a. Accordingly, other functions can be added without impairing the downsizing / thinning of the slide unit 20.

[0041] In the mobile phone 1, the slide unit 20 is downsized and thinned as described above, and thus the mobile phone 1 itself is downsized and thinned. Further, as described above, the slide unit 20 can easily move the movable plate 22 without requiring a complicated mechanism. Therefore, since the mobile phone 1 having the slide unit 20 can be easily opened and closed with one hand, the operability is improved.

In the above-described embodiment, the force with the fixed plate 21 of the slide unit 20 attached to the front surface (outer surface) of the device main body 2 and the movable plate 22 of the slide unit 20 attached to the slide cover 3 is described here. There is no limit. That is, the movable plate 22 of the slide unit 20 may be attached to the device body 2 side, and the fixed plate 21 of the slide unit 20 may be attached to the slide cover 3 side.

[0043] FIGS. 7A, 7B, and 8 are views showing other embodiments of the slide unit of the present invention. In these drawings, reference numeral 40 denotes a slide unit. The main difference between the slide unit 40 and the slide unit 20 lies in the configuration of a mechanism for moving (sliding) the movable plate relative to the fixed plate, and the other configurations are basically the same as those of the slide unit 20.

That is, the slide unit 40 is attached between the fixed plate 41, the movable plate 42 slidably attached to the fixed plate 41, and between the fixed plate 41 and the movable plate 42 as shown in FIG. 7A. And a pair of spring members 43a and an elastic member 43 made of 43a. The fixed plate 41 is, for example, attached to the front surface (outer surface) of the device body 2 in the mobile phone 1 shown in FIGS. 1 and 2, or attached to the inner surface of the slide cover 3, so that both ends of the plate material are almost perpendicular to each other. The fixed plate main body 44 in a bent shape and a pair of thin plates of the fixed plate main body 44 It consists of a pair of panel fixing | fixed part 45 formed inside the part 44a.

[0044] A plurality of screw holes 44b are formed in the fixing plate main body 44, and screws (not shown) are inserted into these holes 44b. When the screw inserted through the hole 44b is screwed into, for example, a screw hole (not shown) formed in the device main body 2 or the slide cover 3, the fixing plate 41 is fixed to the device main body 2 or the slide as described above. Fixed to cover 3.

As shown in FIG. 7B, the panel fixing portion 45 is partially bent so that the tip side is pulled down to the movable plate 22 side. As shown in FIG. 7A, an attachment pin 45a for attaching the spring material 43a is attached to the lowered tip portion, and one end (attachment portion) of the spring material 43a is attached to the attachment pin 45a. 43b is installed.

[0045] Further, the fixed plate main body 44 is bent at the outer side of the thin plate portion 44a with its end bent downward (toward the back side of the mobile phone 1) and further bent outward. As a result, an engagement plate 44c that engages with a later-described guide groove is formed. As shown in FIG. 8, the engaging plate 44c is formed with a plurality of bulged portions 44d that bulge in one surface force arch shape of the outer edge and abut against the inner wall surface of the guide groove. Yes. These bulging portions 44d are formed by drawing and have panel properties that urge in the bulging direction.

A notch 46 is formed on the distal end side (the lower side of the mobile phone 1) of the thin plate portion 44a. In the notch 46, a stopper 46a bent downward (toward the back side of the mobile phone 1) is formed. As shown in FIG. 7A, a stopper 47 formed by bending a part downward is formed on the inner side of the thin plate portion 44a near the position where the panel fixing portion 45 is formed. .

[0047] The movable plate 42 has a shape in which both ends of a plate member on which a plurality of screw holes 42a are formed are bent at substantially right angles, and a screw (not shown) threaded through the hole 42a is, for example, 1, by screwing into the inner surface of the slide cover 3 of the mobile phone 1 shown in FIG. 2 or a screw hole (not shown) formed on the front surface (outer surface) of the device body 2, It can be attached or attached to the front (outside) of the device body 2. As shown in FIG. 7B, a groove is formed on the outer side of the movable plate 42 by bending both ends of the plate material substantially at a right angle. A guide groove 48 is formed. The guide groove 48 relatively guides the above-described engagement plate 44c along the length direction.

[0048] With such a configuration, the movable plate 42 is movable in the length direction of the engagement plate 44c by the guide groove 48 being guided along the engagement plate 44c. The bulging portion 44 formed on the engaging plate 44 c is bulged so as to abut on one side wall surface (inner wall surface) of the guide groove 48. Therefore, when the engagement plate 44c moves relatively inside the guide groove 48, the bulging portion 44d abuts against and presses against the side wall surface of the guide groove 48. Therefore, between the engagement plate 44c and the guide groove 48, Therefore, the movable plate 42 can slide smoothly with respect to the fixed plate 41.

[0049] A stopper pin 49 is fixed to the movable plate 42 by a cash mechanism on the side where the guide groove 48 is formed. A stagger piece 50 is formed on the inner side of the distal end portion of the thin plate portion 44a by bending. As shown in FIG. 7A, movement of the movable plate 42 relative to the fixed plate 41 is restricted by the stopper pin 49 provided on the movable plate 42 coming into contact with the stopper 46a of the fixed plate 41. Yes. When the stopper piece 50 of the movable plate 42 contacts the stopper 47 of the fixed plate 41, movement on the other side is restricted. Therefore, the movable plate 42 is restricted in the movement range with respect to the fixed plate 41 and is not detached from the fixed plate 21.

[0050] Mounting pins 51 are attached to the movable plate 42 on both sides, that is, on the side where the guide groove 48 is formed. The other end portion (attachment portion) 43c of the spring material 43a is attached to the attachment pin 51. Since the mounting position of the mounting pin 51 on the movable plate 42 side is outside the mounting position of the mounting pin 45a on the fixed plate 41 side, when the movable plate 42 moves relative to the fixed plate 41, The attached pin 51 does not interfere with the mounting pin 45a!

[0051] Like the spring material 23a in the slide unit 20, the spring material 43a constituting the elastic member 43 is W-shaped in plan view as shown in FIG. 7A. A loop portion 52 is formed at the center of the spring material 43a.

Accordingly, even in the slide unit 40 of the present embodiment, the operation relating to the elastic member 43 (spring material 43a) and the action effect obtained by this operating force are the same as those of the slide unit 20. [0052] Further, in the slide unit 20 described above, the engaging portion 27 is formed by hemming bending, so that the rail 24c is held without rattling, as shown in FIG. 3B. In this way, a portion crushed by the hemming bending cage is formed outside the rail 24c, and this portion results in a slight increase in the width of the slide unit 20. On the other hand, the slide unit 40 of the present embodiment has a guide that does not rattle between the guide groove 48 by forming the bulging portion 44d on the engaging plate 44c that is not hemmed as described above. The engagement plate 44c can be smoothly moved relative to the groove 48. Therefore, in the slide unit 40, the width can be particularly narrowed and the size can be further reduced. Therefore, the portable product using the slide unit 40 can be miniaturized.

In the above embodiment, the elastic member is formed by two spring members, but the present invention is not limited to this, and the elastic member is formed by one or three or more spring members. Can do. In addition, the spring materials (elastic members) 23a and 43a may have various shapes other than the W shape as long as they are corrugated.

[0054] In each of the above-described embodiments, the mobile phone 1 configured to cover the operation unit such as the key operation unit 7 with the slide cover 3 is shown as the portable product of the present invention. However, the present invention is not limited thereto. For example, the present invention can be applied to, for example, a mobile phone having a configuration in which a functional unit such as a camera unit or a flash is covered with a slide cover, or a digital camera having a configuration in which a lens unit is covered with a slide cover.

[0055] While preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments. Additions, omissions, substitutions, and other modifications can be made without departing from the spirit of the present invention. The present invention is not limited by the above description, but only by the scope of the appended claims.

Industrial applicability

[0056] According to the slide unit of the present invention, the unit itself can be reduced in size and thickness, so that a product using the slide unit can be reduced in size and thickness.

Also, by passing the reversal point of the elastic member, it is possible to reduce the inertia by the inertial restoring force of the elastic member. Thus, the movable plate is configured to be urged in the moving direction, so that the movable plate can be easily moved without requiring a complicated mechanism. Therefore, in a product using a slide unit, for example, by attaching a moving member such as a slide cover to the movable plate, the moving member can be easily moved with one hand, and thus the operability thereof can be improved. I'll do it.
