Description

  The present invention relates to a touch pen for performing input on a touch panel display screen, and an electronic apparatus including the touch pen.

  In various portable electronic devices such as smartphones, tablet computer devices, portable game machines, etc., in which the monitor screen is a touch panel type, as an input means for inputting information and performing operations, A touch pen can be used.

  In order to accommodate such a touch pen when not in use, some electronic devices themselves have a space for accommodating the touch pen. Here, in a simple stick-shaped touch pen, it is necessary to provide a storage space having a size equivalent to the entire length of the touch pen in the electronic device. However, if priority is given to the length of the touch pen, the size of the electronic device is increased. If the length of the touch pen is set in accordance with the size of the electronic device, there is a tendency that the touch pen is too short and difficult to use.

Therefore, it is conceivable that the touch pen itself can be expanded and contracted, the touch pen is extended when used, and the touch pen is contracted when not used and stored in the storage space of the electronic device.
Patent Documents 1 and 2 disclose a configuration in which an extendable touch pen is held in a hole or a recess formed in a casing of an electronic device as such a configuration.

JP 2001-142626 A Japanese Patent Laid-Open No. 6-324882

  However, in the configuration described in Patent Document 1, the touch pen is stored in the storage space in a contracted state, and in use, the touch pen needs to be extended after the touch pen is taken out from the storage space. Further, even when stored, the touch pen must be retracted and then stored in the storage space. That is, the storing / removing operation to / from the storage space and the extending / contracting operation of the touch pen must be performed separately, which is troublesome.

  On the other hand, in the configuration described in Patent Document 2, when not in use, the contracted touch pen is held in a recess formed on the surface of the housing by engaging a hook provided on the touch pen. When using the touch pen, when the touch pen is contracted to disengage the hook from the recess, the touch pen is extended by the spring. Therefore, the storage / removal operation and the expansion / contraction operation of the touch pen are performed during movement, and the above problem can be avoided.

However, in either configuration of Patent Documents 1 and 2, the touch pen must be in a state in which a part of the outer peripheral surface of the touch pen is exposed in a storage space or a recess formed on the surface of the electronic device.
In order to accommodate the entire touch pen in the casing of the electronic device, it is conceivable to provide a hole continuous in the axial direction of the touch pen in the casing, and insert the touch pen into the hole to accommodate the hole. In the configuration described in No. 2, since the touch pen cannot be locked in the hole, the above configuration cannot be employed.
An object of the present invention made there is a touch panel and an electronic device that can be accommodated by inserting and retracting a telescopic touch pen into a hole formed in an electronic device, and that can be easily and reliably taken out and stored. Is to provide equipment.

The present invention employs the following means in order to solve the above problems.
In other words, the touch pen of the present invention includes a tubular member and a pen shaft that can be freely moved in and out of the tubular member, and the pen shaft projects from the contracted state in which the pen shaft is housed in the tubular member. A telescopic touch pen that can be expanded and contracted between the extended state, an urging member that urges the pen shaft in a direction protruding from the tubular member, and the pen shaft is housed in the tubular member A contraction lock mechanism for locking the pen shaft to the cylindrical member when in the contracted state; and an extension lock mechanism for locking the pen shaft to the cylindrical member in the extended state in which the pen shaft protrudes from the cylindrical member; The extension lock mechanism is provided on one of the pen shaft and the cylindrical member, and is locked to a locked portion formed on the other of the pen shaft and the cylindrical member. It penetrates the inside and outside, and one end protrudes from the outer peripheral surface of the cylindrical member. An unlocking member that releases the locking of the locking member to the locked portion by pressing the locking member locked to the locked portion by the other end positioned at It is characterized by that.

  The present invention is an electronic device having a touch panel display screen, and includes a touch pen as described above and a hole that is formed in a housing of the electronic device and is inserted and accommodated in a contracted state. It can also be characterized.

According to the present invention, the pen shaft is locked in the contracted state housed in the cylindrical member by the contraction lock mechanism, and the pen shaft is locked in the extended state protruding from the cylindrical member by the extension lock mechanism. Thereby, the touch pen can be expanded and contracted.
Such a touch pen is inserted into a hole of an electronic device or the like in a contracted state and accommodated, and when it is taken out from the hole, it is in an expanded state so that the touch pen can be accommodated without increasing the size of the electronic device or the like. The touch pen can be used in an extended state with ease of use.
The extension lock mechanism locks the pen shaft to the cylindrical member by locking the locking member to the locked portion in the extended state in which the pen shaft is protruded from the cylindrical member. When the locking member is pressed by the locking release member, the locking of the locking member to the locked portion is released, and the pen shaft can be stored in the cylindrical member.
Since one end of the unlocking member protrudes from the outer peripheral surface of the cylindrical member, when the touch pen is inserted into a hole of an electronic device or the like, the one end of the unlocking member interferes with the inner peripheral surface of the hole. Thus, the locking release member can be moved toward the inside of the cylindrical member, and thereby the locking of the locking member to the locked portion can be released. As described above, the extended touch pen can be shifted to the contracted state only by inserting the touch pen into the hole, and the touch pen can be easily and reliably stored.
When the touch pen housed in the hole in the contracted state is taken out, the pen shaft protrudes from the cylindrical member by the urging member if the locking of the pen shaft to the cylindrical member by the contraction lock mechanism is released, and thereby the hole is Since the touch pen comes out from, the touch pen can be easily taken out.
In this way, the telescopic touch pen can be inserted and accommodated in a hole formed in the electronic device, and the removal and storage operations can be easily and reliably performed.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a best mode for carrying out a touch pen and an electronic device according to the invention will be described with reference to the accompanying drawings. However, the present invention is not limited only to these examples.
1 and 2 are cross-sectional views illustrating the configuration of a touch pen 20 for performing input on a touch panel display screen of a housing 10 of various electronic devices such as a smartphone, a tablet-type electronic device, and a portable game machine. is there.

  The touch pen 20 is inserted and accommodated in a hole 11 formed in the housing 10 of the electronic device and extending in one direction. The touch pen 20 can be expanded and contracted, and as shown in FIG. 2, when it is stored in the hole 11, it is contracted, and as shown in FIG. 1, it is extended when it is taken out from the hole 11 and used. .

As shown in FIG. 1, the touch pen 20 includes a cylindrical outer sleeve (cylindrical member) 30 and a pen shaft 40 provided in the outer sleeve 30 so as to be able to advance and retreat in the axial direction. 40 is advanced and retracted along the axial direction in the outer sleeve 30 and protrudes and retracts with respect to the outer sleeve 30, whereby the contracted state and the extended state are switched.
The touch pen 20 has a contraction lock mechanism 50 for locking the pen shaft 40 in a state where the pen shaft 40 is accommodated in the outer sleeve 30, and locks the pen shaft in a state where the pen shaft 40 protrudes from the outer sleeve 30. And an extension lock mechanism 60.
Hereinafter, these configurations will be described in detail.

  The outer sleeve 30 has a cylindrical shape, one end of which is an opening 31, and the other end is closed by an end plate 32. The end plate 32 has a through hole 33 into which an operation switch (switch) 57 described later is inserted.

  The pen shaft 40 has one end side (hereinafter sometimes referred to as a tip side) as a tapered pen tip portion 41 whose outer diameter decreases as it goes to the tip, and the other end side (hereinafter referred to as this). Is sometimes referred to as a rear end side), a rear end face 42 facing the end plate 32 is formed. A shaft spring (biasing member) 43 made of a coil spring or the like is provided between the rear end face 42 and the end plate 32 in a compressed state, and the pen shaft 40 protrudes from the opening 31 of the outer sleeve 30. Is energized.

  The rear end side of the pen shaft 40 is a small diameter portion 44 whose outer diameter is smaller than the front end side. On the outer peripheral surface of the small-diameter portion 44, a locking recess 51 that constitutes the contraction locking mechanism 50 is formed. Further, a recess 61 constituting the extension lock mechanism 60 is formed on the outer peripheral surface of the intermediate portion between the front end side and the rear end side of the pen shaft 40.

The contraction lock mechanism 50 includes a lock member 53 rotatably provided on a rotation shaft 52 fixed to the inner peripheral surface of the outer sleeve 30, and an operation switch 57.
The lock member 53 is rotatably supported on the side close to the end plate 32 by the rotary shaft 52, and the distal end portion 53 a near the opening 31 has a center side of the outer sleeve 30, that is, the small diameter portion 44 side of the pen shaft 40. A locking claw 54 extending toward the top is formed.
The locking claw 54 engages with the locking recess 51 when the locking member 53 rotates about the rotation shaft 52 and the tip 53a moves in a direction approaching the pen shaft 40. It is possible to stop.

  The lock member 53 is provided with a biasing member 55 such as a spring that biases the tip 53 a in a direction approaching the pen shaft 40 between the tip 53 a and the inner peripheral surface of the outer sleeve 30. .

  A rear end portion of the lock member 53 has an arm 56 that extends from the portion supported by the rotary shaft 52 toward the pen shaft 40.

The operation switch 57 is a disk-shaped operation portion 57a disposed on the outer side (rear) of the outer sleeve 30 with respect to the end plate 32, and extends in the axial direction of the outer sleeve 30 from the operation portion 57a to the front. And a shaft portion 57b extending through a through hole 33 formed in the end plate 32 to a space in which the pen shaft 40 in front of the end plate 32 is accommodated.
A biasing member 58 such as a coil spring is provided between the operation portion 57 a of the operation switch 57 and the end plate 32, and the operation switch 57 is moved from the end plate 32 by the biasing member 58. It is urged toward the separating direction, that is, backward.

  In the contracted state in which the pen shaft 40 is accommodated in the outer sleeve 30 as shown in FIG. 2 and FIG. When the tip 53a of the lock member 53 is pressed toward the pen shaft 40 by the urging member 55, the state in which the pen shaft 40 is locked to the outer sleeve 30 is maintained.

  As shown in FIG. 4, when the operation portion 57a of the operation switch 57 is pressed to the end plate 32 side in the contracted state, the operation switch 57 moves to the end plate 32 side and the shaft portion 57b protrudes from the end plate 32. The amount increases. The arm 56 of the lock member 53 is pressed by the tip portion of the shaft portion 57 b, and the lock member 53 rotates as the rotation shaft 52. As a result, the distal end portion 53 a is separated from the pen shaft 40 against the urging force of the urging member 55. As a result, the locking claw 54 is removed from the locking recess 51, and the locked state of the pen shaft 40 to the outer sleeve 30 is released. Then, the pen shaft 40 is pressed by the biasing force of the shaft spring 43, and the pen shaft 40 protrudes from the outer sleeve 30.

  Thus, the contraction lock mechanism 50 can lock the pen shaft 40 in the contracted state accommodated in the outer sleeve 30. Further, the pen shaft 40 can be protruded from the outer sleeve 30 by the operation of the operation switch 57 to be in the extended state.

As shown in FIG. 5, the extension lock mechanism 60 includes a locking member 62 provided so as to be able to appear and retract in the recess 61, and a release switch (locking release member) 63 provided on the outer sleeve 30 side.
The locking member 62 has an L-shaped cross section having a base portion 62a having a thickness that can be accommodated in the recess 61, and a locking claw 62b protruding from the rear end portion of the base portion 62a toward the outer sleeve 30 side. It is made into a shape.
An urging member 64 such as a spring is provided between the base portion 62 a and the recess 61. By this urging member 64, the locking member 62 is urged toward the outer peripheral side in the radial direction of the outer sleeve 30 from the concave portion 61, that is, the side that protrudes from the concave portion 61 to the outer peripheral side and approaches the outer sleeve 30.

On the inner peripheral surface of the outer sleeve 30, a locking recess (locked portion) is provided at a position facing the locking claw 62 b of the locking member 62 when the pen shaft 40 is extended from the outer sleeve 30. 65 is formed.
By inserting the locking claw 62b of the locking member 62 biased to the outer peripheral side by the biasing member 64 into the locking recess 65, the pen shaft 40 moves in the axial direction relative to the outer sleeve 30. It is restrained and locked in the extended state protruding from the outer sleeve 30.

  The outer sleeve 30 is formed with a through-hole 66 that penetrates the outer sleeve 30 at a position facing the base portion 62 a of the locking member 62 when the pen shaft 40 is extended from the outer sleeve 30. Yes. A release switch 63 for releasing the lock of the pen shaft 40 by the locking member 62 is provided in the through hole 66.

  The release switch 63 has a columnar shape having an axis in a direction penetrating the inside and outside of the outer sleeve 30 (the radial direction of the outer sleeve 30), an outer peripheral end (one end) 63 a positioned on the outer peripheral side of the outer sleeve 30, and the outer sleeve 30. Between the inner peripheral end (the other end) 63b located on the inner peripheral side of this, there is a flange portion 63c protruding to the outer peripheral side orthogonal to the axis of the release switch 63.

  On the other hand, the through-hole 66 of the outer sleeve 30 is formed with a recess 67 that accommodates the flange portion 63 c at an intermediate portion between the outer peripheral side and the inner peripheral side of the outer sleeve 30. In the recess 67, the dimension in the direction connecting the outer peripheral side and the inner peripheral side of the outer sleeve 30 is set to be larger than the thickness of the flange portion 63c. As a result, the flange portion 63 c is movable within the range of the recess 67 in the direction connecting the outer peripheral side and the inner peripheral side of the outer sleeve 30 (the radial direction of the outer sleeve 30). That is, the release switch 63 is movable within a certain stroke range along the direction connecting the outer peripheral side and the inner peripheral side of the outer sleeve 30.

  In the release switch 63, the inner peripheral end 63 b of the outer sleeve 30 is a diameter-expanded portion 63 d that is enlarged in a direction orthogonal to the axis of the release switch 63. The enlarged diameter portion 63d is adapted to abut against the base portion 62a of the locking member 62 when the pen shaft 40 is in the extended state protruding from the outer sleeve 30.

  In the release switch 63, a chamfered portion (inclined surface) 63m inclined at, for example, 45 ° with respect to the insertion direction of the touch pen 20 into the hole 11 is formed on the front end side of the outer peripheral end portion 63a of the outer sleeve 30. .

  In order to increase the frictional resistance on the surface of such a release switch 63, the entire release switch 63 may be formed of a rubber-based material, or at least the surface of the outer peripheral end 63a may be coated with a rubber-based material or the like. good.

  In such an extension lock mechanism 60, as shown in FIG. 1, when the pen shaft 40 is in the extended state protruding from the outer sleeve 30, the locking recess 65 formed on the inner peripheral surface of the outer sleeve 30 The locking claw 62b of the locking member 62 biased to the outer peripheral side by the biasing member 64 is inserted. As a result, the pen shaft 40 is locked to the outer sleeve 30 and its movement in the axial direction is restricted. In this way, the pen shaft 40 is locked in the extended state protruding from the outer sleeve 30. In this state, the release switch 63 is pressed to the outer peripheral side of the outer sleeve 30 by the base portion 62 a of the locking member 62, and the outer peripheral end portion 63 a protrudes from the outer sleeve 30 to the outer peripheral side.

  In this extended state, when the release switch 63 is pushed into the inner peripheral side of the outer sleeve 30, the locking member 62 is pushed toward the pen shaft 40. Then, the locking claw 62b and the locking recess 65 are unlocked, and the restriction of the pen shaft 40 in the axial direction of the outer sleeve 30 is released. As a result, the pen shaft 40 can be accommodated in the outer sleeve 30.

  As shown in FIG. 1, when the pen shaft 40 is housed in the outer sleeve 30 and inserted into the hole 11, the base 62 a of the locking member 62 is housed in the recess 61. In this state, the release switch 63 is configured such that the outer peripheral end portion 63 a hits the inner peripheral surface of the hole 11 and the inner peripheral end portion 63 b hits the outer peripheral surface of the pen shaft 40. Further, the release switch 63 is set to have a length in the radial direction of the outer sleeve 30 so that the outer peripheral end portion 63a exerts a certain or greater frictional force at the portion where the outer peripheral end 63a abuts the hole 11.

Next, a method for storing and taking out the touch pen 20 as described above from the housing 10 of the electronic device will be described.
The touch pen 20 as described above is housed in a contracted state in which the pen shaft 40 is housed in the outer sleeve 30 in the hole 11 formed in the housing 10 of the electronic device, as shown in FIG. In this contracted state, as described above, in the touch pen 20, the locking claw 54 is locked to the locking recess 51, and the tip 53 a of the lock member 53 is pressed toward the pen shaft 40 by the urging member 55. Thus, the locked state is maintained.
In this state, the operation portion 57 a of the operation switch 57 located at the rear end portion of the touch pen 20 is exposed from the hole 11 to the outer peripheral portion of the housing 10.

When the user takes out the touch pen 20 from the hole 11, as shown in FIG. 3, the operation part 57 a of the operation switch 57 exposed on the outer peripheral part of the housing 10 is pushed toward the inside of the hole 11. Then, the operation switch 57 moves to the end plate 32 side, and the arm 56 of the lock member 53 is pressed by the distal end portion of the shaft portion 57b. Thereby, the locking member 53 rotates as the rotating shaft 52, and the locking state of the locking claw 54 and the locking recess 51 is released.
Then, the pen shaft 40 is pressed by the biasing force of the shaft spring 43, and the pen shaft 40 protrudes from the outer sleeve 30. The protruding pen shaft 40 hits the bottom 11 a of the hole 11, and the reaction force causes the outer sleeve 30 of the touch pen 20 to protrude from the hole 11 to the outer peripheral side of the housing 10.

  At this time, the outer peripheral end 63a of the release switch 63 comes into contact with the inner peripheral surface of the outer sleeve 30 and exhibits a frictional force. Accordingly, it is possible to give a sense of resistance to the operation when the outer sleeve 30 of the touch pen 20 protrudes from the hole 11 and to prevent the touch pen 20 from inadvertently jumping out of the hole 11.

  The user holds the outer sleeve 30 protruding from the hole 11 and pulls out the touch pen 20 from the hole 11. In this state, as shown in FIG. 1, the pen shaft 40 is extended from the outer sleeve 30 by the urging force of the shaft spring 43, and the locking recess 65 formed on the inner peripheral surface of the outer sleeve 30 is in the extended state. The locking claw 62b of the locking member 62 biased to the outer peripheral side by the biasing member 64 is inserted. As a result, the pen shaft 40 is locked in the extended state protruding from the outer sleeve 30. In this state, the user can use the touch pen 20 to input information and input operations on the display screen of the electronic device.

When the touch pen 20 is accommodated in the hole 11, the user inserts the touch pen 20 into the hole 11 from the pen tip 41 side. Then, as shown in FIG. 6, the outer peripheral end 63 a of the release switch 63 protruding from the outer sleeve 30 to the outer peripheral side hits the opening peripheral edge 11 b of the hole 11. Since the chamfered portion 63m is formed in the release switch 63, when the touch pen 20 is further inserted into the hole 11 with the chamfered portion 63m abutting against the opening peripheral edge portion 11b, as shown in FIG. The release switch 63 is pushed into the inner peripheral side of the outer sleeve 30. Here, it is preferable to form a chamfered portion (inclined surface) 11m that is inclined with respect to the insertion direction of the touch pen 20 into the hole 11 so that the release switch 63 can be smoothly pushed.
When the release switch 63 is pushed into the inner peripheral side of the outer sleeve 30, the locking member 62 is pushed into the pen shaft 40, and the engagement between the locking claw 62b and the locking recess 65 is released. Then, the pen shaft 40 can slide in the axial direction with respect to the outer sleeve 30. In this state, when the touch pen 20 is further pushed into the hole 11, the pen tip 41 hits the bottom 11 a of the hole 11 and the pen shaft 40 is accommodated in the outer sleeve 30.

As shown in FIGS. 2 and 3, the locking claw 54 of the lock member 53 is opposed to the locking recess 51 formed in the rear end portion of the pen shaft 40 inserted into the outer sleeve 30. In this position, the locking claw 54 engages with the locking recess 51 because the tip 53a of the locking member 53 is pressed toward the pen shaft 40 by the biasing member 55.
In this state, the release switch 63 is sandwiched between the inner peripheral surface of the hole 11 and the outer peripheral surface of the pen shaft 40, whereby the contracted touch pen 20 is restrained while being inserted into the hole 11.

As described above, the touch pen 20 includes the contraction lock mechanism 50 that locks the pen shaft 40 to the outer sleeve 30 in the contracted state in which the pen shaft 40 is housed in the outer sleeve 30, and the pen shaft 40 from the outer sleeve 30. By including an extension lock mechanism 60 that locks the pen shaft 40 to the outer sleeve 30 in the protruding extended state, the pen shaft 40 can be extended and contracted.
The extension lock mechanism 60 pushes the release switch 63 whose one end protrudes toward the outer periphery of the outer sleeve 30 toward the inner side of the outer sleeve 30, thereby locking the pen shaft 40 to the outer sleeve 30. The locking member 62 is operated and the locking with the outer sleeve 30 is released. Thereby, the touch pen 20 in the stretched state is inserted into the hole 11, and the release switch 63 is pressed by the interference with the hole 11, thereby unlocking the stretched state and contracting the touch pen 20. .
That is, the touch pen 20 can be contracted simply by inserting the touch pen 20 into the hole 11, and the touch pen 20 can be smoothly inserted and contracted into the hole 11 without taking time and effort. It can be carried out.

  Further, the touch pen 20 inserted into the hole 11 in the contracted state is held in the hole 11 by the release switch 63 of the extension lock mechanism 60 being pressed against the inner peripheral surface of the hole 11, and the contraction lock mechanism 50. Thus, the pen shaft 40 is maintained in the contracted state housed in the outer sleeve 30. Thereby, in order to hold the touch pen 20 in the hole 11, it is not necessary to perform any particular operation, and it is only necessary to insert the touch pen 20 into the hole 11, and the touch pen 20 is stored in the housing 10 of the electronic device. Operation can be performed easily and reliably.

Furthermore, when the touch pen 20 held in the hole 11 in the contracted state is taken out, if the operation switch 57 is pushed in, the lock in the contracted state is released, and the touch pen 20 is extended by the biasing force of the shaft spring 43 and comes out of the hole 11. Accordingly, the touch pen 20 can be easily and reliably removed from the housing 10 of the electronic device.
In this manner, the telescopic touch pen 20 can be inserted and accommodated in the hole 11 formed in the electronic device, and the take-out and storage operations can be easily and reliably performed.

  Further, the release switch 63 is formed of a rubber-based material as a whole, or a coating made of a rubber-based material or the like is applied to the surface of the release switch 63 so that the touch pen 20 suddenly exits from the hole 11. Can be prevented from jumping out, and smooth movement with resistance can be achieved.

Similarly, for example, the lock member 53 of the contraction lock mechanism 50 is provided on the pen shaft 40 side, and the position of the pen shaft 40 is fixed by fitting the lock member 53 on the outer sleeve 30 side when the touch pen 20 contracts. Such a structure may be used.
Furthermore, the structure for preventing the touch pen 20 from coming out of the hole 11 regardless of the user's intention when the touch pen 20 is stored may be a method other than that shown in the embodiment. For example, a protrusion may be provided on the outside of the touch pen 20 and a recess may be provided in the hole 11 so that the protrusion fits into the recess and is fixed when the touch pen 20 is stored.
In addition, the structure for contracting the touch pen 20 may be a structure other than that shown in the embodiment. For example, in the embodiment, the touch pen 20 has a two-stage configuration of the pen shaft 40 and the outer sleeve 30. However, the touch pen 20 is further divided into three stages or more so that the entire touch pen 20 is further contracted. But it ’s okay.
In addition to this, as long as it does not depart from the gist of the present invention, the configuration described in the above embodiment can be selected or changed to another configuration as appropriate.
