Description

  The present invention relates to an input device and a portable terminal including the same.

  FIG. 14 is an external view of a conventional mobile terminal 100. As shown in FIG. 14, a conventional portable terminal 100 is integrally provided with an operation unit (also referred to as an input unit; hereinafter the same) 101 as an input device, and in addition, a display unit 102, an audio output unit 103, and an audio input unit 104. Etc.

  In addition, an input key, a function key, a selection key, and an enter key are arranged on the operation unit 101 of the mobile terminal. The input keys are 12 types of keys composed of numeric keys from 0 to 9, * key, and # key. The function key is a key for calling a function such as “clear”, “memo”, and “manner”. When a user performs an operation, a method of holding the portable terminal 100 with one hand and operating an input key, a function key, a selection key, and a determination key with the thumb of the one hand is generally used.

  FIG. 15 is a diagram illustrating main muscles related to finger movements required when the user operates the conventional portable terminal 100. The total finger extensor muscle 200 and the shallow finger flexor muscle 201 are required when the portable terminal 100 is gripped. That is, the total finger extensor muscle 200 is required when extending four fingers other than the thumb, and the shallow finger flexor muscle 201 is a muscle required when bending four fingers other than the thumb. Further, the short thumb extensor 202 and the long thumb flexor 203 are required when operating the input keys on the operation unit 101. That is, the short thumb extensor muscle 202 is required when the thumb is abducted, and the long thumb flexor muscle 203 is a muscle required when bending the thumb.

  That is, the user grasps the portable terminal 100 by activating the total finger extensor 200 and the superficial finger flexor muscle 201, moves the thumb to the input key by activating the short thumb extensor 202, and the long thumb An input key is pressed by activating the flexor 203. As described above, the user performs an input operation mainly using the four types of muscles.

  FIG. 16 is a diagram for explaining a burden placed on the thumb when the portable terminal 100 including the conventional input device is operated. Here, an area far from the base of the thumb is called “area A”, and an area near the base of the thumb is called “area B”.

  FIG. 17 is a diagram illustrating the degree of activity applied to the four muscles when the user operates the mobile terminal 100. The degree of activity is measured as the muscular strength (measured as a voltage value) exerted by the four muscles when the user operates the mobile terminal 100, and as the maximum muscular strength (maximum voluntary contraction force as well as the voltage value) of each muscle. ) Normalized. Here, the average value of the activity levels when four users press a predetermined key ten times continuously is used. It can be said that the closer this value is to 100, the greater the burden on the operation because the user is operating with a force close to the maximum muscular strength. As shown in FIG. 17, the activity level of each muscle when a key in area A in FIG. 16 (for example, numeric key 1) is pressed is determined by the key in area B in FIG. 9) is less than the activity level of each muscle.

  As described above, the conventional mobile terminal 100 does not have a key arrangement that takes into account an area in which the hand / finger performing the operation is easy to operate. In other words, when operating a key in a region far from the base of the thumb, the burden on the hand / finger to be operated is relatively small, but the closer the key is to the base of the thumb, the closer to the hand / finger. It takes a big burden. Further, when the input key is disposed below the base of the thumb, in order to operate the input key, the thumb must be largely abducted while holding the terminal with four fingers other than the thumb, The burden on the four muscles increases. For this reason, the greater the number of key operations, the greater the burden on the hands and fingers performing the operation, which may cause mental and physical fatigue. In addition, if fatigue has accumulated in the hand or finger performing the operation, there is a possibility of dropping and damaging the portable terminal.

  This problem has remarkably emerged as a large number of keys are arranged in a narrow area of the portable terminal as the portable terminal has become smaller and more multifunctional in recent years. In particular, in character input operations such as e-mail, as the number of characters that can be sent by e-mail increases, the possibility of causing mental and physical fatigue has increased. In view of this, there has been proposed a compact information equipment terminal that improves the operability of the input key and reduces finger fatigue even when the key operation is performed for a long time (see Patent Document 1).

FIG. 18 is a diagram showing a small information device terminal 300 disclosed in Patent Document 1. The small information device terminal 300 has at least a display 301 and input keys 302 on the front surface. The input key 302 is disposed relatively above the display 301 when the small information device terminal 300 is held with one hand. For this reason, when the small information device terminal 300 is held with one hand, the thumb naturally comes close to the input key 302, so that the burden on the hand or finger performing the operation can be reduced.
JP 2002-27059 A

  However, when the small information device terminal 300 disclosed in Patent Document 1 is held with one hand, the display 301 is disposed under the input key 302, so that depending on the position of the input key 302, the operating hand or finger In some cases, the display content of the display 301 may be hidden. Specifically, if the upper left input key 302 in FIG. 18 is operated with a thumb that is normally used, the base of the thumb may cover and hide the screen. Therefore, the user must operate the thumb with an unnatural motion to prevent such a situation, and the mental and physical burdens are not alleviated so much.

  The above-mentioned problem is that not only a mobile terminal but also a mobile phone or a remote controller, for example, must be operated with one hand, space is limited for miniaturization, and an input key is arranged on the edge of the base The same thing happened in the device.

  The present invention solves the above-described problems, and provides an input device that can reduce the operational burden without requiring excessive movement of the hand or thumb that performs the operation when operating the input key. For the purpose.

  In order to achieve the above object, an input device according to the present invention is an input device for inputting information, and has a base having an input unit for inputting information, and a grip position of the device for separating the input unit from the input unit. A gripping member. As a result, since the grip position of the device is separated from the input unit, it is possible to reduce the burden on the hand or thumb that performs the operation, and it is possible to improve the operability. In addition, since the gripping member for improving the operability is provided separately from the base body, there is an effect that the downsizing of the apparatus is not limited.

  Here, the gripping member may be provided so as to be able to appear and retract on the base body by a pull-out type, a detachable type, a rotary type, a slide type, or a foldable type. Accordingly, the size can be reduced by a pull-out type, a detachable type, a rotary type, a slide type, or a foldable type.

  The gripping member may be formed as a substantially U-shaped member, and the base may have a substantially U-shaped storage portion that stores the gripping member. As a result, the gripping member can be accommodated in the base body without affecting the arrangement of other members, so that it is possible to avoid an increase in the thickness of the apparatus.

  The input device may further include an adjustment unit that adjusts the degree to which the gripping member is separated from the input unit. This makes it possible to flexibly adjust the form of the input device according to the size of each user's hand, finger length, etc., so the user should take a gripping posture that does not place a burden on the hand or finger. Will be able to.

  The gripping member may be provided at one end of the base body close to the input unit. As a result, when the input device is held with one hand, the display unit is arranged above the input unit, so that it is possible to avoid the problem that the display content of the display unit is hidden by the hand or finger operating the input unit. It becomes.

  The base may include a display unit that displays information, and the gripping member may be configured to be disposed at one end of the base far from the display unit. As a result, when the input device is held with one hand, the input unit is arranged below the display unit, so that it is possible to avoid a problem that the display content of the display unit is hidden by a hand or a finger operating the input unit. It becomes.

  The base may include a display unit that displays information, and the gripping member may be configured to be disposed on the opposite side of the display unit with the input unit interposed therebetween. As a result, when the input device is held with one hand, the display unit is arranged on the opposite side across the input unit, so that the display content of the display unit is hidden by the hands and fingers operating the input unit. It becomes possible.

  Note that the present invention can be realized not only as such an input device, but also as a portable terminal including characteristic means included in such an input device.

  As is clear from the above description, according to the input device according to the present invention, since the grip position of the device is separated from the input unit, it is possible to reduce the burden on the hand or finger performing the operation and to improve the operability. It becomes possible to improve. In addition, since the gripping member for improving the operability is provided separately from the base body, there is an effect that the downsizing of the apparatus is not limited.

  For example, even when operating a device in which a plurality of input keys are arranged in a small area, such as a miniaturized portable terminal, the user can put a burden on the hand or finger by pulling out the gripping member. It becomes possible to take a gripping posture that does not apply. For this reason, the operability can be improved by reducing the burden on the hand or finger performing the operation, and the user can operate comfortably.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the drawings. In the following drawings, the same elements will be described using the same reference numerals.

(First embodiment)
1st Embodiment is described using FIG.1, FIG.2, FIG.3 and FIG.

  FIG. 1 is an external view of a portable terminal 1 including an input device 2 according to the first embodiment of the present invention. The mobile terminal 1 is a communication terminal with a built-in antenna. That is, it has functions for realizing telephone calls, mail transmission / reception, Internet connection, etc., and can communicate with other terminals and base stations. When using a mail transmission / reception function, an Internet connection function, or the like, characters can be input using the input device 2. The mobile terminal 1 includes a voice output unit 3, a voice input unit 4, a display unit 5, and a drawer switch 6 on the front surface. The audio output unit 3 is a speaker or the like that outputs audio. The voice input unit 4 is a microphone or the like for inputting voice. The display unit 5 is a liquid crystal display or the like that displays various types of information, and displays information such as characters as shown in FIG. The drawer switch 6 will be described later.

  The input device 2 provided in the portable terminal 1 includes a character input key 7, a function call key 8, a direction key 9, and an enter key 10. The character input keys 7 are 12 types of keys for inputting characters, numbers, and symbols. The function call key 8 is a key for calling each function (such as a mail function, a call function, a Web function, and a clear function) of the mobile terminal 1. The direction key 9 is a key for selecting a desired function or character from a plurality of functions or characters. The determination key 10 is a key for determining selection by the direction key 9. Using this input device 2, the user calls a desired function or inputs characters.

  FIG. 2 is a diagram showing an area where the burden on the hand and thumb is large and small when the user operates the mobile terminal 1 including the input device 2 according to the first embodiment of the present invention with the right hand. . As shown in FIG. 2, when operating the character input key 7 in the area A (for example, the character input key for inputting 1, 2, 4, 5, 7, * shown in FIG. 1), the thumb is extended. Therefore, the burden on the hand and thumb is small. On the other hand, when operating the character input key 7 in the region B (for example, the character input key for inputting 3, 6, 8, 9, 0, # shown in FIG. 1), the thumb is bent and is cramped. Because of the posture, the burden on the thumb is large. When a long-time operation or a mail with a large number of characters is created, the thumb repeatedly bends and stretches, further increasing the operation burden.

  FIG. 3 is an external view when the drawer member 11 of the portable terminal 1 provided with the input device 2 in the first embodiment of the present invention is pulled out. Since the drawer member 11 has a strength that does not change its shape even when it is gripped, the user can perform key operations while holding the drawer member 11. Here, the drawer member 11 is an example of a gripping member in the present invention.

  The pull-out member 11 is pulled out from the base portion 12 by depressing the pull-out switch 6, and is disposed at one end portion of the base portion 12 close to the input portion (one end portion of the base portion 12 far from the display portion 5). Here, the input unit is a group of keys such as a character input key 7, a function call key 8, a direction key 9, and an enter key 10. The base portion 12 is the mobile terminal 1 excluding the drawer member 11. As shown in FIG. 3, since the input unit is provided below the display unit 5 and the display unit 5 is provided above the input unit, one end (display) of the base unit 12 close to the input unit is provided. The one end part of the base part 12 far from the part 5 corresponds to the lower end part of the base part 12 in FIG. If the drawer member 11 is arranged at the lower end portion of the base portion 12 in this way, a gripping member is provided separately from the base portion 12 provided with the key. As a result, it is not necessary to operate the key near the lower end of the base 12 in a bent state toward the base of the thumb as in the prior art, and the operability is improved.

  Further, the drawer member 11 is disposed at one end of the base 12 close to the input unit, thereby avoiding a problem that the display content of the display unit 5 is hidden by a hand or a finger operating the input unit. It becomes possible. In particular, when the drawer member 11 is disposed on the opposite side of the display unit 5 with the input device 2 interposed therebetween as shown in FIG. It is possible to operate without performing an unnatural operation that puts a burden on the finger.

  FIG. 4 shows a state where the user operates the portable terminal 1 with the right hand while the drawer member 11 of the portable terminal 1 having the input device 2 according to the first embodiment of the present invention is pulled out. It is a figure showing the area | region with a large burden, and a small area | region. As shown in FIG. 4, when the user grips the drawer member 11, the position of the input device 2 is disposed at an upper portion relative to the user's hand or thumb. Accordingly, the number of character input keys 7 arranged in the region B near the base of the thumb is reduced, and the number of character input keys 7 arranged in the region A far from the base of the thumb is increased. In other words, the frequency with which the character input key 7 arranged in the area B is operated is lowered, and the frequency with which the character input key 7 arranged in the area A is operated is increased.

  As already described, the burden on the hand and thumb when operating the character input key 7 in the area A is small, and the burden on the hand and thumb when operating the character input key 7 in the area B is large. Therefore, if the drawer member 11 is operated with the drawer member 11 being pulled out, the burden on the hand or finger performing the operation can be reduced compared to the case where the drawer member 11 is operated without being pulled out.

  FIG. 5 is a diagram illustrating an internal structure of the mobile terminal 1 including the input device 2 according to the first embodiment of the present invention. FIG. 5A shows a state before the drawer member 11 is pulled out. FIG. 5B shows a state after the drawer member 11 is pulled out.

  As shown in FIG. 5A, the drawer member 11 is formed as a substantially U-shaped member. As shown in FIG. 5B, a storage groove (storage portion) 11 a for storing the substantially U-shaped drawer member 11 is formed on the side surface of the base portion 12. When the drawer member 11 is stored in the storage groove 11 a, the side surface of the base portion 12 is covered with the drawer member 11. Accordingly, the user can fix the base portion 12 with one hand and pull out the drawer member 11 with the other hand. Such a substantially U-shaped drawer member 11 can be stored in the base portion 12 of the mobile terminal 1 without affecting the arrangement of other members. For this reason, even if the portable terminal 1 is provided with the drawer member 11, the thickness does not increase as compared with the conventional portable terminal. Therefore, it is possible to reduce the burden on the hands and fingers performing the operation while maintaining the downsizing of the conventional portable terminal. In addition, although the said storage groove | channel 11a provided in the side surface of the base | substrate part 12 was shown as an example of the storage part of this invention, the storage part may be comprised in the base | substrate part 12. FIG.

  FIG. 6 is a diagram illustrating the structures of the base body portion 12 and the drawer member 11 of the mobile terminal 1 including the input device 2 according to the first embodiment of the present invention. FIG. 6A is a front view and a side view of the base portion 12. FIG. 6B is a front view and a side view of the drawer member 11.

  The base portion 12 and the drawer member 11 are coupled by a slide mechanism (adjustment portion) 13. The slide mechanism 13 has convex portions 14 and 15 on both sides of the base portion 12 and the drawer member 11, respectively. By engaging the convex portion 14 of the base portion 12 and the convex portion 15 of the drawer member 11, the drawer member 11 can be pulled out from the base portion 12 step by step. As a result, the length with which the drawer member 11 is pulled out from the base portion 12 can be flexibly adjusted according to the size of each user's hand, the length of the finger, and the like. For this reason, it is possible to reduce the burden on the hand or finger performing the operation according to the size of the user's hand or finger.

  In the present embodiment, the drawer member 11 and the slide mechanism 13 are configured as described above. However, the present invention is not limited to this configuration, and the drawer member 11 is pulled out from the base portion 12 step by step. Any configuration can be used.

  FIG. 7 is a diagram illustrating a state in which the drawer member 11 is pulled out by pressing the drawer switch 6 of the portable terminal 1 including the input device 2 according to the first embodiment of the present invention. FIG. 7A shows a state before the drawer switch 6 is pressed. FIG. 7B shows a state after the drawer switch 6 is pressed.

  As shown in FIG. 7A, when the user depresses the drawer switch 6 in a state where the drawer member 11 is housed in the base portion 12 of the portable terminal 1, the drawer member as shown in FIG. 11 is automatically pulled out from the base portion 12. Accordingly, since the user can save time and effort to manually pull out the drawer member 11 from the base portion 12, it is possible to further reduce the burden on the user during operation. As described above, a configuration using an elastic body such as a spring is typical as a configuration in which the drawer member 11 is automatically pulled out by pressing the drawer switch 6. That is, when the drawer member 11 is housed in the base portion 12, the spring is fixed in a contracted state, and when the drawer switch 6 is pressed, the fixed state is released and the spring is extended to extend the drawer member. 11 is pulled out from the base portion 12.

  As described above, according to the mobile terminal 1 including the input device 2 in the first embodiment of the present invention, when the drawer switch 6 is pressed to pull out the drawer member 11 and grip the drawer member 11, character input is performed. Since the key 7 and the like are arranged in an area where the hand and fingers are not burdened, the user can perform key operations without burdening the hands and fingers, improving operability and comfortable operation.

  In the present embodiment, the voice input unit 4 is disposed on the base unit 12 of the mobile terminal 1, but the voice input unit 4 may be disposed on the drawer member 11. With such a configuration, even when a call is made using a miniaturized portable terminal, the user can place the voice input unit 4 near the mouth by pulling out the drawer member 11 and is comfortable. Calls are possible.

  In the present embodiment, the drawer member 11 is pulled out from the base portion 12 by depressing the drawer switch 6. However, the drawer member 11 is pulled out from the base portion 12 by sliding the drawer switch 6. It is good also as a structure.

  Moreover, the apparatus provided with the input device 2 of the present invention is not limited to a portable terminal. Needless to say, the present invention can be applied to a device that holds a device with one hand and operates with a finger of one hand, such as a remote controller used for operation of a television or audio.

  The drawer member 11 in the present embodiment is an example of a gripping member according to the present invention. The gripping member is a member for separating the grip position (described later) of the device from the input unit. As described above, the input unit is a group of keys such as the character input key 7, the function call key 8, the direction key 9, and the decision key 10. Therefore, it can be said that the grip member is a member for separating these key groups from the grip position. As the input unit, a touch sensor, a wheel, a jog dial, or the like can be used. In this case, the grip member is a member for separating the touch sensor, the wheel, the jog dial, and the like from the grip position.

  FIG. 8 is a diagram for explaining a grip position. FIG. 8A shows a state in which the portable terminal 1 in a state where the drawer member 11 is not pulled out is gripped with the right hand. On the other hand, FIG. 8B shows a state in which the mobile terminal 1 in a state where the drawer member 11 is pulled out is gripped with the right hand. As shown in this figure, when the mobile terminal 1 is operated with the right hand, since the key operation is performed using the thumb of the right hand while the mobile terminal 1 is held with the right hand, the palm at the base of the thumb of the right hand is the base portion 12. Or it will contact the holding member 11. In the present invention, the contact position 30 is referred to as a “grip position”. FIG. 8A shows a state before the grip position is moved away from the input unit (input key), the drawer member 11 is not pulled out, and the grip position is on the base 12 and is the same as the input key. Becomes a height position. On the other hand, FIG. 8B shows a state after the grip position is moved away from the input unit (input key). The drawer member 11 is pulled out, and the grip position is positioned below the input key. Thus, if the drawer member 11 is used, the input key can be separated from the grip position.

  Of course, how to hold the mobile terminal 1 may differ depending on the user. For example, when the user operates the portable terminal 1 with the left hand, the grip position appears on the left side, but the other points are the same as when operated with the right hand. That is, FIG. 9A shows a state before the grip position is moved away from the input unit (input key), the drawer member 11 is not pulled out, and the grip position is at the same height as the input key. . On the other hand, FIG. 9B shows a state after the grip position is moved away from the input unit (input key). The drawer member 11 is pulled out, and the grip position is positioned below the input key.

  The present invention is effective when the portable terminal 1 or the like is grasped for the purpose of operation, and is not effective when grasped for other purposes (for example, the purpose of carrying). In other words, the portable terminal 1 may be gripped for the purpose of carrying it, but the grip position in that case is not the “grip position” as used in the present invention. The “grip position” in the present invention is a position where the palm of the base of the thumb gripped for the purpose of operation comes into contact with the base portion 12 or the gripping member 11.

  Here, the pull-out type gripping member is illustrated, but the form in which the gripping member is projected and retracted from the base portion 12 is not limited to the pull-out type. That is, the gripping member can be made to appear and disappear from the base portion 12 by a detachable type, a rotary type, a slide type, or a foldable type.

  FIG. 10 is a diagram illustrating the mobile terminal 1 that employs the detachable gripping member 11. 10A shows a state before mounting the gripping member 11, FIG. 10B shows a state in the middle of mounting the gripping member 11, and FIG. 10C shows the gripping member 11 completely. It shows the state of wearing. Convex portions 22 are formed inside both end portions of the substantially U-shaped gripping member 11, and concave portions 21 into which the convex portions 22 are fitted are formed on the side surfaces of the base portion 12. In order to facilitate attachment / detachment of the gripping member 11, the gripping member 11 preferably has moderate elasticity. Thus, even when the configuration in which the gripping member 11 is detachable is employed, the same effect as that in the case of employing the configuration in which the gripping member 11 is projected and retracted can be obtained. In addition, when the portable terminal 1 is not operated, it is only necessary to remove the gripping member 11, so that not only the portable terminal 1 can be reduced in size but also can be reduced in weight. Although the substantially U-shaped holding member 11 is assumed here, the shape of the holding member 11 is not particularly limited.

  FIG. 11 is a diagram illustrating the mobile terminal 1 that employs the rotary gripping member 11. 11A shows a state before the gripping member 11 appears, FIG. 11B shows a state in the middle of the appearance of the gripping member 11, and FIG. 11C shows the gripping member 11 completely. The state which appeared in is shown. As described above, when the configuration in which the gripping member 11 protrudes and retracts is employed, the same effect as that in the case where the configuration in which the gripping member 11 protrudes and retracts is employed can be obtained. Here, the plate-like gripping member 11 is assumed, but the shape of the gripping member 11 is not particularly limited.

  FIG. 12 is a diagram illustrating the mobile terminal 1 that employs a sliding gripping member 11 at the bottom of the base body 12. 12A shows a state before the gripping member 11 appears, FIG. 12B shows a state in the middle of the gripping member 11, and FIG. 12C shows the gripping member 11 completely. The state which appeared in is shown. Thus, even when the configuration in which the gripping member 11 is projected and retracted is employed, the same effect as that in the case of employing the configuration in which the gripping member 11 is projected and retracted can be obtained. Here, the plate-like gripping member 11 is assumed, but the shape of the gripping member 11 is not particularly limited. Moreover, although the holding member 11 is provided at the bottom of the base portion 12, it may be configured to be housed inside.

  FIG. 13 is a diagram illustrating the mobile terminal 1 that employs the foldable gripping member 11. FIG. 13A shows a state before the gripping member 11 appears, FIG. 13B shows a state in the middle of the appearance of the gripping member 11, and FIG. The state which appeared in is shown. As described above, even when the configuration in which the gripping member 11 is folded up and down is employed, the same effect as that in the case of employing the configuration in which the gripping member 11 is projected and retracted can be obtained. Here, the plate-like gripping member 11 is assumed, but the shape of the gripping member 11 is not particularly limited.

  The input device according to the present invention has a feature that reduces a burden on a hand or a finger that performs an operation, and is useful as an input device for a mobile phone.
