JP-A-7-288860

  However, since the conventional portable terminal device shown in Patent Document 1 is rotatably connected to each other around an axis in a direction perpendicular to the inner surface of the two casings on the closed side, for example, When the external force is applied from the side surface direction of the housing when it is accommodated in the bag or pocket, the two housings may be opened from each other. In this state, there is a possibility that the external housing is damaged when the external force is further applied.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a portable terminal device that can prevent two housings from being unexpectedly opened when carried.

  In order to solve the above problems, the present invention proposes the following means.

  The invention according to claim 1 includes two housings and a connecting portion that connects the two housings so as to be openable and closable, and the connecting portion is provided in one of the two housings. A first rotating part and a second rotating part provided in the other housing, the first and second rotating parts being connected to each other so as to be rotatable around a reference axis, and the first rotating part A first hole that opens on a surface facing the second rotating part is formed in the rotating part, and at least the two casings are closed and / or opened in the second rotating part. A second hole is formed opposite the first hole in a state, and a locking member that is movable in the axial direction of the first hole is provided in the first hole. Is not opposed to the second hole, the locking member is immersed in the first hole, and the first hole is inserted into the second hole. When it is facing, the front end of the locking member is configured to protrude from the first hole into the second hole, and the first hole and the second hole are opposed to each other. And a holding mechanism for holding the locking member in a state where at least a distal end portion of the locking member protrudes into the second hole, and the two housings are closed and / or opened. Detecting means for detecting that the holding member is in a state of being held, and controlling the holding mechanism in accordance with a signal from the detecting means to hold the distal end portion of the locking member in a state of protruding into the second hole. A control unit is provided.

  According to the mobile terminal device of the present invention, when the at least two housings are closed and / or opened, the distal end portion of the locking member is projected from the first hole to the second hole. Therefore, relative rotation of the first and second rotating parts can be suppressed. Therefore, even if an external force is applied from the side of the casing, the relative positions of the two casings are not easily shifted.

  Further, according to the portable terminal device of the present invention, the holding member can hold the locking member so that at least the tip end portion of the holding member protrudes from the first hole to the second hole. The relative rotation of the first and second rotating parts can be completely prevented. As a result, at least two housings can be kept closed and / or opened.

  Further, according to the mobile terminal device of the present invention, when the two casings are closed and / or opened, the control unit controls the holding mechanism based on the signal from the detection means to Since the two housings are fixed to each other so as not to rotate, the two housings do not open each other.

  According to a second aspect of the present invention, in the mobile terminal device according to the first aspect, a tip end portion of the locking member is tapered.

  According to the portable terminal device according to the present invention, the locking member protruding into the second hole can be smoothly immersed in the first hole with the relative rotation of the first and second rotating portions. Can do. Note that when the distal end portion of the locking member of the present invention is tapered, the width of the locking member in the rotational direction of at least the second rotating portion is gradually narrowed in the state of being inserted into the first hole. It is formed in a shape.

  According to a third aspect of the present invention, in the portable terminal device according to the first or second aspect, when the first hole is not opposed to the second hole, the distal end portion of the locking member is moved to the second portion. When the first hole is opposed to the second hole, the tip of the locking member is protruded from the first hole into the second hole. A support mechanism for supporting the locking member is provided.

  According to the portable terminal device of the present invention, when the at least two housings are closed and / or opened, relative rotation of the first and second rotating portions can be suppressed, and a predetermined amount can be determined. By applying a force greater than the value and immersing the locking member into the first hole, the first and second rotating parts are rotated relative to each other, and one casing is rotated with respect to the other casing. Can be made.

  According to a fourth aspect of the present invention, in the portable terminal device according to the third aspect, the support mechanism is an elastic body that supports a rear end portion of the locking member.

  According to the portable terminal device according to the present invention, the support mechanism for the locking member can be easily configured, and an increase in the number of components can be suppressed.

  The holding mechanism is disposed at the rear end of the locking member in the protruding direction to prevent the locking member from retreating, and is separated from the holding position to allow the locking member to retreat. A holding member that is movable between the retracted position and a drive unit that moves the holding member may be used.

  According to the mobile terminal device of the present invention, when the holding member is moved to the holding position by the driving unit, at least the tip of the locking member cannot be retracted from the second hole to the inside of the first hole. Therefore, the relative rotation of the first and second rotating parts is completely prevented by the locking member. Therefore, the relative positional relationship between the two housings can be reliably maintained.

  In addition, when the holding member is moved to the retracted position by the drive unit from this state, the locking member can be retracted into the first hole, so that the locking member is immersed in the first hole. By doing so, the two casings can rotate with respect to each other.

  Moreover, it is good also as having an operation part and a control part which controls the said holding mechanism based on operation of this operation part.

  According to the mobile terminal device according to the present invention, when the user of the mobile terminal device performs a predetermined operation on the operation unit in a state where the two housings are closed or opened, based on an instruction from the control unit, The holding mechanism holds the locking member in a state of protruding from the first hole to the second hole. Thereby, two housings can maintain a relative positional relationship and do not move from a closed state or an open state.

  In this state, when the user performs a predetermined operation on the operation unit, the holding mechanism sets the locking member to be movable in the axial direction of the first hole based on an instruction from the control unit. As a result, the two housings can be rotated with respect to each other, and the two housings can be relatively rotated.

  As described above, according to the first aspect of the invention, when the at least two housings are closed and / or opened, the distal end portion of the locking member is removed from the first hole through the second hole. Since it is made to project into the hole, relative rotation of the first and second rotating parts can be suppressed. For this reason, even if an external force is applied from the side of the casing, the positions of the two casings in the closed state and / or the opened state are not easily shifted. As a result, the two casings can be maintained in a predetermined positional relationship, and in particular when the two casings are carried in a bag in a closed state, the two casings open to each other, and further external force is applied. It is possible to prevent the mobile terminal device from being damaged by the above.

  According to the first aspect of the present invention, the holding member can hold the locking member so that at least the tip end portion of the holding member protrudes from the first hole to the second hole. The relative rotation of the second rotating part can be completely prevented. As a result, when carrying, the two casings do not unexpectedly open each other, and the mobile terminal device can be reliably prevented from being damaged.

  Furthermore, according to the first aspect of the present invention, when the two casings are closed to each other, the holding mechanism fixes the two casings so that they cannot rotate with respect to each other based on an instruction from the control unit. Therefore, when carrying, the two casings are not opened unexpectedly, and damage to the mobile terminal device can be prevented more reliably.

  According to the invention which concerns on Claim 2, the locking member which protrudes in the 2nd hole can be smoothly immersed in the 1st hole with relative rotation of the 1st, 2nd rotation part. .

  According to the third aspect of the invention, when at least two casings are closed and / or opened, relative rotation of the first and second rotating portions can be suppressed and the two casings can be prevented. By applying a force of a predetermined value or more when starting the operation of opening the bodies or closing the body, the tip of the locking member protruding into the second hole is immersed in the first hole and Since the 1st and 2nd rotation parts can be rotated relatively, two cases can be rotated from a closed state and / or an open state, and a click feeling can be obtained.

  According to the invention which concerns on Claim 4, the support mechanism of a locking member can be comprised easily, and the increase in a number of parts can be suppressed.

  In addition, if the locking member is held by the holding member at a position that prevents relative rotation of the first and second rotating portions, the two housings can be reliably fixed to each other so as not to rotate.

  In addition, since the driving unit moves the holding member between the holding position and the retracted position, the two housings can be switched between a state in which the two housings are fixed so as not to rotate and a state in which the two cases can rotate.

  Further, if the holding mechanism is controlled by a user operation of the mobile terminal device, the two housings can be easily switched between a state in which the two housings can rotate and a state in which the two housings do not rotate. it can.

  1 to 7 show one embodiment according to the present invention, and the embodiment described here is a case where the present invention is applied to a mobile phone. As shown in FIGS. 1 and 2, a mobile phone (mobile terminal device) 1 according to this embodiment includes a first casing 2, a second casing 3, and these two casings 2 and 3. It is provided with a connecting portion 4 that is rotatable about an axis (reference axis) L1 that is perpendicular to the surfaces facing each other when they are combined, and that can be opened and closed.

  The inner surface 2a of the first housing 2 is provided with a first operation portion 7 composed of various pressable operation keys such as a call key and an end key, and a microphone 9 is provided at the front end portion 2b. Is provided. The side surface 2c of the first housing 2 is provided with a second operation portion 11 composed of a plurality of pressable operation keys. The second operation portion 11 includes two housings 2, 3 is exposed to the outside regardless of the open / closed state.

  A display unit 13 is provided on a surface 3a of the second casing 3 that faces in the same direction as the inner surface 2a of the first casing 2, and the display unit 13 includes the first and second casings. Regardless of the open / closed state of a few, it is exposed to the outside. In addition, a speaker 15 is provided on the front end portion 3b of the second housing 3 in the surface 3a.

  As shown in FIGS. 3 and 4, the connecting portion 4 includes a first rotating portion 21 provided in the first housing 2 and a second rotating portion 22 provided in the second housing 3. I have. The first and second rotating portions 21 and 22 are formed in a substantially cylindrical shape, and are coupled to each other so as to be rotatable around the axis L1.

  A through hole (first hole) 23 penetrating in the direction of the axis L1 is formed in the first rotating portion 21, and the through hole 23 is movable only in the axial direction of the through hole 23. A stop member 25 is provided. Of the locking member 25, the distal end portion 25a on the second rotating portion 22 side is formed in a convex shape so that the width gradually decreases, and it is preferable to form the distal end portion 25a in a curved surface. .

  The locking member 25 is urged in a direction toward the second rotating portion 22 by a spring (support mechanism) 27. One end of the spring 27 is fixed to the locking member 25, and the other end is fixed to the first housing 2.

  Of the second rotating part 22, a pair of holes (second holes) 29, 29 are formed on the surface 22 b facing the first rotating part 21. In the state where the housings 2 and 3 are closed to each other and the state in which the housings are opened to each other, the housings 2 and 3 are positioned to face the through-holes 23 of the first rotating unit 21.

  In a state in which the two casings 2 and 3 are closed or open from each other, as shown in FIG. 3, the distal end portion 25 a of the locking member 25 is urged by the spring 27 and the second through the through hole 23. Is set so as to protrude and be supported on the rotating portion 22 side. In this state, when the force for relatively rotating the first and second rotating parts 21 and 22 around the axis L1 is smaller than the biasing force of the spring 27, the first and second rotating parts 21 and 22 do not rotate relative to each other. Therefore, when the two casings 2 and 3 are closed and opened, mutual movement of the two casings 2 and 3 is restricted by the urging force of the spring 27.

  In this state, when the first and second rotating parts are rotated with each other by a force exceeding the urging force of the spring 27, the distal end portion 25a of the locking member 25 formed in a curved surface is in the second shape. Since the front end portion 25a is pressed by the surface 22b of the rotating portion 22 and has a narrow width, the locking member 25 can be smoothly inserted into the through hole 23 as shown in FIG. In this state, the first and second rotating parts 21 and 22 can be freely rotated with respect to each other.

  Further, the first housing 2 is provided with a holding member 31 that holds at least the distal end portion 25 a of the locking member 25 in a state of protruding into the hole 29.

That is, as shown in FIG. 3, when the locking member 25 is engaged with the hole 29, there is a gap 33 between the first housing 2 and the rear end of the locking member 25. Yes. The holding member 31 is movable between a holding position that enters the gap 33 and a retracted position that is separated from the gap 33. The holding member 31 is sandwiched between the first casing 2 and the locking member 25 as shown in FIG. In this state, the locking member 25 cannot be immersed in the through hole 23.

  The holding member 31 is formed in a wedge shape, and the locking member 25 is further advanced into the hole 29 when moving to the holding position. Therefore, in this state, the first and second rotating parts 21 and 22 are mutually connected regardless of the magnitude of the force that relatively rotates the first and second rotating parts 21 and 22 around the axis L1. Does not rotate. In other words, the first and second casings 2 and 3 are fixed in a non-rotatable manner (hereinafter referred to as a locked state).

  The movement of the holding member 31 is performed by the principle of an electromagnet. That is, the holding member 31 is made of a magnet, and an electromagnet (driving unit) 35 is disposed adjacent to the holding member 31. Then, by supplying electric power to the electromagnet 35, the holding member 31 is pulled away from the electromagnet 35 and enters the gap 33, or pulled toward the electromagnet 35 and separated from the gap 33. The polarity of the electromagnet 35 is determined based on an instruction from the control unit described later.

  The holding member 31 and the electromagnet 35 constitute a holding mechanism 101 that can hold the locking member 25 in a state of protruding into the hole 29.

  As shown in FIG. 6, the mobile phone 1 includes a detection unit 37 that detects the open / closed state of the two casings 2, 3, a memory unit 39 that stores various information, and a second operation unit. 11, a signal from the detection unit 37, and a control unit 41 that controls the holding mechanism 101 based on various information in the memory unit 39.

  Therefore, for example, when the operation keys of the second operation unit 11 are continuously pressed for a predetermined time in a state where the two casings 2 and 3 are closed, the holding mechanism 101 is based on an instruction from the control unit 41. Electric power is supplied to the electromagnet 35, and the holding member 31 is moved to the holding position to be locked.

  Also, for example, when the two casings 2 and 3 are closed and left for a predetermined time, the control unit 41 measures the elapsed time based on the signal from the detection means 37, and the elapsed time and the memory unit 39. Is compared with the specified time stored in When the elapsed time reaches the specified time, similarly to the above, electric power is supplied to the electromagnet 35 based on an instruction from the control unit 41, and the holding member 31 moves to the holding position and enters the locked state.

  Here, the specified time is the time from when the two casings 2 and 3 are closed to the locked state, and can be arbitrarily set by the user of the mobile terminal device 1. Therefore, for example, the two casings 2 and 3 may be set to be locked at the same time as closing each other.

  In the locked state, the first operation unit 7 is covered by the second housing 3 and thus cannot be operated. In addition, operations for outputting various information stored in the memory unit 39 cannot be performed. All the functions provided in the mobile phone 1 such as a call function are disabled. That is, for example, even if an incoming call signal or mail is received, it is not possible to make a call or check the contents of the mail unless the locked state is released.

  In this state, as shown in FIG. 7, an icon 45 is displayed on the display unit 13 to notify that the lock state is established.

  In order to release this locked state, it is necessary to input a password for permitting the use of the mobile phone 1 in the second operation unit 11 and collate it with the password stored in the memory unit 39.

  That is, when any operation key of the second operation unit 11 is pressed in the locked state, a password input screen is displayed on the display unit 13. On the password input screen, 1 to 0 numeric buttons 46, an enter button 47, and the like are displayed, and these can be selected by the second operation unit 11.

  Here, when the number button 46 or the enter button 47 is selected by the operation key of the second operation unit 11 and the password is input, the password input by the control unit 41 and the password stored in the memory unit 39 are collated. . When the collation results match, electric power is supplied to the electromagnet 35 based on an instruction from the control unit 41, and the locked state described above is released. If both passwords do not match, the locked state is continuously maintained.

  When the locked state is released, the icon 45 disappears from the display unit 13, and the two casings 2 and 3 can be rotated with respect to each other. In addition, various information stored in the memory unit 39 is displayed on the display unit 13, and various functions of the mobile phone 1 such as a call function can be used.

  A method of using the mobile phone 1 configured as described above will be described.

  When the mobile phone 1 is carried, as shown in FIG. 2, the two casings 2 and 3 are in a closed state, and the two casings 2 and 3 cannot be rotated with respect to each other. It is locked. In this locked state, various functions of the mobile phone 1 such as a call function cannot be used.

  Therefore, when using the mobile phone 1 from this state, the locked state is released.

  That is, the operation key of the second operation unit 11 is pressed to display the password input screen on the display unit 13. Next, a password is input in the second operation unit 11 while visually recognizing the display unit 13. If the entered password matches the password stored in the memory unit 39, the locked state is released, the two casings 2 and 3 can be rotated with respect to each other, and the mobile phone 1 Functions can be used, and various types of information stored in the memory unit 39 can be displayed on the display unit 13.

  Even when an external force that rotates the second housing 3 with respect to the first housing 2 is applied in the unlocked state, the external force is smaller than the urging force of the spring 27. Since the front end portion 25a of the locking member 25 is maintained in a state of projecting into the hole 29, the two casings 2 and 3 can be prevented from rotating relative to each other and maintained in a closed state.

  Next, for example, in order to make a call from this closed state, a force larger than the urging force of the spring 27 is applied to rotate the second housing 3 around the axis L1 with respect to the first housing 2. Move. At this time, since the distal end portion 25a of the locking member 25 is formed in a curved surface having a narrow width, the surface 22b of the second rotating portion 22 pushes down the locking member 25 and penetrates the distal end portion 25a. In order to be immersed in the hole 23, the second housing 3 is rotated relative to the first housing 2 by 180 ° around the axis L1 so that the two housings 2 and 3 are opened. Then, the first operation unit 7 is operated to start a call through the microphone 9 and the speaker 15.

  When the use of the mobile phone 1 is finished, the second housing 3 is closed with respect to the first housing 2 and the mobile phone 1 is accommodated in a bag or pocket. In this case, the operation key of the second operation unit 11 is continuously pressed for a predetermined time, or left for a predetermined time to enter a locked state.

  As described above, according to the mobile phone 1, when the two casings 2 and 3 are closed, the user of the mobile phone 1 presses the operation key of the second operation unit 11 to lock the mobile phone 1. It can be. For this reason, it is possible to easily prevent the two casings 2 and 3 from opening unexpectedly in a state where the cellular phone 1 is housed in a bag or pocket, and damage to the cellular phone 1 can be easily prevented.

  Further, even if the user of the mobile phone 1 does not perform the above-described operation, it can be brought into a locked state by leaving the two housings 2 and 3 closed for a predetermined time. That is, since the two casings 2 and 3 can be locked in accordance with the operation of closing each other, the cellular phone 1 can be reliably prevented from being damaged when the cellular phone 1 is carried.

  Furthermore, since the holding member 31 is arranged at the holding position, the locking member 25 is held at a position where relative rotation of the two rotating parts 21 and 22 is suppressed, so that this locked state is reliably realized. be able to.

  Further, by moving the holding member between the holding position and the retracted position by the electromagnet 35, it is possible to easily switch between the locked state and the unlocked state.

  Further, in the locked state, the first operation unit 7 is not operable, and various information stored in the memory unit 39 is not output, and all the various functions provided in the mobile phone 1 are unusable. Furthermore, since this locked state is released according to the password verification result, it is possible to reliably prevent the mobile phone 1 from being used without permission by other people and to protect the privacy.

  Further, since the spring 27 is configured to project the locking member 25 from the through hole 23 of the first rotating portion 21 toward the second rotating portion 22, 2 in the state where the locked state is released. When the two casings 2 and 3 are opened and closed, a click feeling due to the immersion / protrusion of the locking member 25 can be obtained.

  In the above embodiment, the locked state is released only by inputting the password. However, the present invention is not limited to this. For example, by pressing the operation key of the second operation unit 11 for a predetermined time. It may be canceled. In this case, the locked state can be quickly released when an incoming call or mail is received. Further, for example, the lock state may be released based on an incoming call signal or an incoming mail signal.

  Furthermore, the two casings 2 and 3 can be locked only when they are closed to each other. However, the present invention is not limited to this. For example, as shown in FIG. It may be possible to lock the doors when they are open to each other. In this case, when the mobile phone 1 is used, the two casings 2 and 3 are securely held in an open state, so that the second casing with respect to the first casing 2. The operability of the mobile phone 1 can be improved without rotating the 3.

  In this case, the lock state may be set and released not only by the second operation unit 11 but also by the first operation unit 7.

  Furthermore, the input of information such as a password is performed on the first and second operation units 7 and 11, but the present invention is not limited to this. For example, the display unit 13 is a so-called touch panel, and a predetermined position of the display unit 13 is set. Information may be input by touching. In this case, it is not necessary to provide the second operation unit 11, and input of information is facilitated.

  In the locked state, all the functions of the mobile phone 1 such as a call function are disabled. However, the present invention is not limited to this, and some or all of the functions of the mobile phone 1 may be usable.

  Further, the two rotating parts 21 and 22 are superposed in the direction of the axis L1, but the present invention is not limited to this, and the two rotating parts 21 and 22 are connected to each other so as to be rotatable around the axis L1. That's fine. Therefore, for example, as shown in FIG. 8, the second rotating portion 22 formed in a columnar shape may be inserted into the first rotating portion 21 formed in a cylindrical shape. In this configuration, the through hole 23 is formed in a direction orthogonal to the axis L1, and the locking member 25 is movable only in a direction orthogonal to the axis L1.

  Further, when the holding member 31 enters the gap 33, the locking member 25 is further advanced into the hole 29. However, the holding member 31 is not limited to this, and the locking member 25 projects at least into the hole 29. What is necessary is just to hold | maintain in the state which carried out.

  In addition, the holding member 31 is moved by magnetic force, but is not limited thereto, and any member that moves according to an instruction from the control unit 41 may be used. Therefore, for example, the holding member 31 may be moved by the driving force of the motor.

  Further, the holding member 31 is used to realize the locked state. However, the present invention is not limited to this, and the two casings 2 and 3 may be configured to be immovable from each other by the locking member 25. Good. That is, for example, the locking member 25 may be formed of a magnet, and the locking member 25 may be moved between the inside of the through hole 23 and the inside of the hole 29 by the electromagnet 35.

  Further, although the locking member 25 is biased by the spring 27 in a direction in which the locking member 25 protrudes toward the second rotating portion 22, the present invention is not limited thereto, and at least the locking member 25 is moved to the second rotating portion 22. What is necessary is just a support mechanism which supports it so that it may protrude to the side. However, when an elastic body such as the spring 27 is used, the support mechanism of the locking member 25 can be easily configured, and the number of parts of the support mechanism can be reduced. It is preferable to use it.

  Further, the mobile phone 1 is not limited, and for example, a so-called foldable mobile phone in which two housings rotate around an axis parallel to the inner surface of the first housing 2 may be used. In this case, the display unit 13 provided in the second housing 3 may be provided on the inner surface on the side covered with the first housing 2. However, in this case, since the input of the password cannot be confirmed on the display unit 13, for example, a separate display unit may be provided at a position that is always exposed to the outside. It may be limited to 11 simple operations.

  Furthermore, the present invention is not limited to the mobile phone 1 and may be a mobile terminal device in which two casings are connected to each other by a connecting portion and can be freely opened and closed, such as a PDA or a notebook computer.

  As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.
