Description

  The present invention relates to an electronic device having a push button, and more particularly to a mounting structure of a switch corresponding to the push button.

  For example, electronic devices such as portable computers have push buttons such as a power switch button and a click switch button. The push button is arranged on the outer wall of the housing and can be pushed with a fingertip of a hand.

  For example, an electronic device that can reduce the installation space of a push button is provided (see, for example, Patent Document 1). The electronic device described in Patent Literature 1 includes a housing, a push button, and a click switch. The housing includes an outer wall having an opening. The push button has a button body and an arm. One end of the arm is supported by the inner peripheral edge of the opening of the outer wall, and supports the button main body in a displaceable manner. According to such an electronic device, the button body and the arm are held in a positional relationship where they overlap each other, and the installation space for the push button is reduced.

  Here, the user does not always press the center portion of the button body, and often presses the peripheral end portion off the center of the button body. The peripheral end portion of the button body opposite to the portion connected to the arm is a so-called cantilever tip. When the user presses such a peripheral end portion, the button main body is sunk into the casing with the pressed peripheral end portion causing maximum deflection. On the other hand, the central portion of the button body located above the switch has a smaller deflection than the peripheral end portion pressed by the user.

  Therefore, when the user presses the peripheral end portion of the button body, the center portion of the button body is not displaced so as to contact the switch, and there is a possibility that the switch may not be operated normally. In other words, the push buttons and switches as described above may not function uniformly depending on where they are pressed in the button body, and the operability of the push buttons cannot be said to be high.

  An object of the present invention is to obtain an electronic device that improves the operability of a push button.

  In order to achieve the above object, an electronic device according to one aspect of the present invention includes a housing having an opening, a left button provided in the opening, a right button provided in the opening, A left switch that is provided in the housing and faces the left button; and a right switch that is provided in the housing and faces the right button, and each of the left button and the right button is the housing.

  Next, the first and second arms 32 and 33 will be described. The first and second arms 32 and 33 are examples of a support portion supported by the housing 7 and another support portion, respectively. Here, the first and second arms 32 and 33 of the left button 24a will be described. Regarding the right button 24b, it is sufficient to reverse the left and right descriptions of the first and second arms 32 and 33 of the left button 24a. Therefore, the same reference numerals are given to configurations having the same functions, and the description thereof is omitted. To do.

  As shown in FIGS. 2 and 3, the first arm 32 includes a first member 32 a and a second member 32 b. The first member 32a of the left button 24a extends from the left rear portion of the button main body 31 toward the left wall 7c, and is bent in a direction in which the front end portion faces the front wall 7b. The second member 32b of the left button 24a extends from the left front portion of the button main body 31 toward the left wall 7c and is bent in a direction in which the tip portion faces the rear wall 7e.

  The first member 32a and the second member 32b have their front ends integrally coupled to each other, and have a first fixing portion 32c at the joint. The first fixing portion 32c has a slightly larger thickness than the first member 32a or the second member 32b, and a first through hole 32d is provided in the center.

  The second arm 33 includes a third member 33a and a fourth member 33b. The third member 33a of the left button 24a extends from the front left part of the button main body 31 toward the front wall 7b and is bent in a direction in which the tip part faces the right wall 7d. The fourth member 33b of the left button 24a extends from the front right part of the button main body 31 toward the front wall 7b and is bent in a direction in which the tip part faces the left wall 7c. That is, the second arm 33 extends along the direction intersecting the direction facing the first arm 32 from the central portion of the left button 24a.

  The tips of the third member 33a and the fourth member 33b are integrally connected to each other, and the second fixing portion 33c is provided at the connecting portion. The second fixing portion 33c has a slightly larger thickness than the third member 33a or the fourth member 33b, and a second through hole 33d is provided at the center.

  The fourth member 33b of the left button 24a and the fourth member 33b of the right button 24b are connected to each other and formed integrally. A notch 33e is provided at the center of the portion where the left button 24a and the right button 24b are connected. The notch 33 e is notched in an arc shape corresponding to the outer shape of the position adjusting boss 17.

  As shown in FIG. 3, the left and right buttons 24a and 24b are attached to the left and right button attaching portions 16a and 16b by inserting the first support protrusions 20 into the first through holes 32d and the second through holes. This is done by inserting the second support protrusion 21 into 33d. At this time, the position adjustment of the left and right buttons 24a and 24b is favorably performed by placing the notch 33e along the position adjusting boss 17.

  After the first and second support protrusions 20 and 21 are inserted into the first and second through holes 32d and 33d, respectively, the protruding ends of the first and second support protrusions 20 and 21 are connected to the first and second support protrusions 20 and 21, respectively. It welds to the fixing | fixed part 32c, 33c. As a result, one end of the first arm 32 is fixed to the first support protrusion 20, and the first arm 32 is supported by the housing 7. Furthermore, one end of the second arm 33 is fixed to the second support protrusion 21, and the second arm 33 is supported by the housing 7.

  Thereby, as shown in FIGS. 2 and 5, the button main body 31 is supported by the first and second arms 32 and 33 and held by the housing 7. Since the button main body 31 and the arms 32 and 33 have elasticity, the button main body 31 can be displaced between a position away from the switches 25a and 25b and a position touching the switches 25a and 25b. When the user presses the button body 31, the button body 31 is displaced toward the switches 25a and 25b, and the switches 25a and 25b are operated by touching the switches 25a and 25b.

  The first to fourth members 32a, 32b, 33a, 33b have a curved portion 34 in a part thereof. The curved portion 34 is a portion where the first to fourth members 32 a, 32 b, 33 a, 33 b are curved in the thickness direction of the housing 7. Since the first to fourth members 32a, 32b, 33a, 33b have the curved portion 34, the elasticity of the first and second arms 32, 33 is enhanced.

  The housing 7 includes left and right switches 25a and 25b. As shown in FIGS. 4 and 5, the left and right switches 25a and 25b are disposed below the left and right buttons 24a and 24b corresponding to the left and right buttons 24a and 24b, respectively. In other words, the left and right buttons 24a and 24b are arranged on the housing 7 so as to face the switches 25a and 25b so that the switches 25a and 25b can be operated.

  The left and right switches 25 a and 25 b are a kind of contact switch, and include a switch body 41 and a switch top 42. The switch top 42 is provided so as to be displaceable with respect to the switch body 41 at the uppermost part of the left and right switches 25a and 25b. The left and right switches 25a and 25b sense that the switches 25a and 25b are operated when the switch top 42 is pressed in the direction toward the switch body 41.

  As shown in FIG. 4, the left switch 25a is disposed below the pressing protrusion 31c of the left button 24a. The left switch 25a is decentered by a distance s1 from the center A of the button body 31 toward the right wall 7d along the longitudinal direction of the housing 7, and the rear wall 7e along the depth direction of the housing 7. It is provided eccentrically by a distance s2.

  In other words, the left switch 25a is biased away from the first support protrusion 20 of the left button mounting portion 16a and away from the second support protrusion 21 with the center A of the button body 31 as a base point. Has been placed. In other words, the left switch 25a is offset from the center A of the button main body 31 so that the deflection increases in the button main body 31 when the left button 24a is pressed. The left switch 25 a is disposed at a position offset from the center of the left button 24 a away from the first arm 32 and offset away from the second arm 33.

  The right switch 25b is disposed below the pressing protrusion 31c of the right button 24b. The right switch 25b is decentered by a distance s1 from the center A of the button body 31 toward the left wall 7c along the longitudinal direction of the casing 7, and toward the rear wall 7e along the depth direction of the casing 7. The distance s2 is eccentric.

  In other words, the right switch 25b is biased away from the first support protrusion 20 of the right button mounting portion 16b and away from the second support protrusion 21 with the center A of the button body 31 as a base point. Has been placed. More specifically, the right switch 25b is offset from the center A of the button main body 31 so that the deflection increases in the button main body 31 when the right button 24b is pressed. The right switch 25b is disposed at a position offset from the center of the right button 24b away from the first arm 32 and offset away from the second arm 33.

  For example, the left and right switches 25a and 25b according to the present embodiment are arranged eccentrically at substantially the center between the center A of the second opening 15 and the peripheral edge of the second opening 15 along the respective eccentric directions. Yes.

  The left and right switches 25 a and 25 b are mounted on the first circuit board 26. The first circuit board 26 is further electrically connected to the second circuit board 27, and is electrically connected to a main circuit board (not shown) via the second circuit board 27.

Next, the operation of the portable computer 1 will be described with reference to FIGS.
FIG. 6 schematically shows the relationship between the left button 24 a, the left switch 25 a, and the first support protrusion 20. The relationship between the left button 24a, the left switch 25a, and the second support protrusion 21, and the relationship between the right button 24b, the right switch 25b, and the first or second support protrusion 20, 21 are the same.
The button 24a is a cantilever whose one end is supported by the support protrusion 20, and can be displaced along a direction approaching the switch 25a and a direction away from the switch 25a.

  FIG. 7 is a diagram illustrating a state in which the user presses the peripheral end 51 located opposite to the portion connected to the arm 32 in the button main body 31. When the user presses the button 24a, the button 24a is displaced toward the switch 25a due to its own elasticity. When the pressing protrusion 31c of the button body 31 contacts the switch top 42 of the switch 25a, the switch body 41 detects that the button 24b has been pressed and outputs a signal to that effect.

  FIG. 8 is a diagram illustrating a state in which the user has pressed the central portion 52 of the button main body 31. In this case as well, the button body 31 is displaced toward the switch 25a in the same manner as when the peripheral end 51 is pressed. When the pressing protrusion 31c of the button body 31 contacts the switch top 42 of the switch 25a, the switch body 41 senses that the button 24a has been pressed and outputs a signal to that effect.

  According to the portable computer 1 having such a configuration, the switches 25a and 25b can be easily turned on even when the peripheral end of the button body 31 is pushed, and the operability of the buttons 24a and 24b is improved.

In order to obtain a uniform operational feeling over the entire button body 31, it seems to be better to arrange the switches 25 a and 25 b below the center A of the button body 31, for example.
FIG. 11 schematically shows a state in which the switch 25 a is arranged corresponding to the center of the button body 31 and the peripheral end 51 located opposite to the portion connected to the arm 32 in the button body 31 is pushed. FIG. Since the peripheral end portion 51 corresponds to the tip portion of the cantilever, it is more flexible than the central portion 52 of the button main body 31.

  That is, when the user presses the peripheral end portion 51 of the button body 31, the central portion 52 of the button body 31 is not displaced so as to come into contact with the switch 25a, and the switch 25a is not normally operated. In other words, when the peripheral end 51 of the button main body 31 is pressed, the switch 25a is not operated unless it is pressed with a larger stroke than when the central portion 52 of the button main body 31 is pressed.

  On the other hand, the switch 25 a according to the present embodiment is arranged to be decentered with respect to the center A of the button body 31. That is, the switch 25a is eccentric so as to be away from the support protrusion 20 (that is, the fulcrum) with the center A of the button body 31 as a base point.

  Therefore, as shown in FIG. 7, even when the peripheral end 51 of the button main body 31 is pressed, if the button main body 31 is displaced by a distance about the gap between the button main body 31 and the switch 25a, the switch 25a Operated.

  Further, as shown in FIG. 8, even when the center portion 52 of the button body 31 is pressed, the switch 25a is operated if the button body 31 is displaced by a distance about the gap between the button body 31 and the switch 25a. The That is, the switch 25a itself becomes one fulcrum for supporting the button 24a. Thus, the button 24a is in a so-called doubly supported state in which both ends are supported by the support protrusion 20 and the switch 25a. If both ends of the button 24a are supported, when the central portion 52 of the button body 31 is pressed, the button 24a does not bend greatly even if the switch 25a is not disposed below the button 52a. Therefore, the user can stably press the button 24a.

  As described above, by decentering the switch 25a with respect to the center A of the button main body 31, the switch 25a can easily enter evenly regardless of the pressed portion of the button main body 31. In other words, the switch 25a is operated when the button body 31 is pressed with a stroke equal to or less than a predetermined amount regardless of the pressed part of the button body 31.

  The portable computer 1 according to the present embodiment further includes a second arm 33 and a second support protrusion 21 as another arm and another arm support portion. By having the second arm 33 and the second support protrusion 21, the button body 31 is supported from a different direction from the first arm 32, and the button body 31 is held more stably.

  The switches 25a and 25b are eccentric in the opposite direction to both the first support protrusion 20 and the second support protrusion 21 with the center A of the button body 31 as a base point. For example, consider a case where the portable computer has only the first support protrusion 20 and the first arm 32, and the switch 25 a is eccentric only with respect to the first support protrusion 20. In this case, when the right end of the button body 31 is pressed, the switch is stably operated as described above, but the front end or the rear end of the button body 31 is pressed. Sometimes, the central part of the button body 31 is not displaced so much and the operability is not so good.

  However, like the portable computer 1 according to the present embodiment, when the second support protrusion 21 and the second arm 33 are provided and the switches 25a and 25b are also eccentric with respect to the second support protrusion 21, the button The switches 25a and 25b are stably operated even when the front end or the rear end of the main body 31 is pushed, and the operability of the switches 25a and 25b is further enhanced.

  In particular, when the second support protrusion 21 is provided along a direction orthogonal to the direction from the second opening 15 toward the first support protrusion 20, at the entire peripheral end of the button body 31. Operability is improved.

  If the switches 25a and 25b are provided eccentrically with respect to the center A of the second opening 15 up to a substantially central portion between the center and the periphery of the second opening 15, the operability of the buttons 24a and 24b is improved. Since the effect of the present invention of improvement is more easily exhibited, it is preferable.

  Next, a portable computer 61 according to a second embodiment of the present invention will be described with reference to FIG. In addition, the structure which has the same function as the portable computer 1 which concerns on 1st Embodiment attaches | subjects the same code | symbol, and abbreviate | omits the description. The left and right buttons 62a and 62b of the portable computer 61 are supported by the first arm 32, respectively.

  The pressing protrusion 31 c of the left button 62 a is provided eccentric to the center A of the button main body 31 by a distance s 1 toward the right wall 7 d along the longitudinal direction of the housing 7. The pressing protrusion 31c of the right button 62b is provided eccentric to the center A of the button main body 31 by a distance s1 along the longitudinal direction of the housing 7 toward the left wall 7c.

  The left switch 25a is provided eccentrically by a distance s1 from the center A of the button body 31 toward the right wall 7d along the longitudinal direction of the housing 7. In other words, the left switch 25a is arranged to be biased away from the first support protrusion 20 of the left button mounting portion 16a with the center A of the button body 31 as a base point.

  The right switch 25b is provided eccentrically by a distance s1 from the center A of the button body 31 toward the left wall 7c along the longitudinal direction of the housing 7. In other words, the right switch 25b is offset from the center A of the button main body 31 and away from the first support protrusion 20 of the right button mounting portion 16b.

  According to the portable computer 61 having such a configuration, even when the peripheral end of the button body 31 is pressed, the switches 25a and 25b can be easily turned on, and the operability of the buttons 62a and 62b is improved. That is, by decentering the switches 25a and 25b with respect to the center A of the button main body 31, even if the peripheral end portion along the width direction of the casing 7 is pressed in the button main body 31, the stroke is less than a certain amount. The switches 25a and 25b are operated.

  Next, a portable computer 71 according to a third embodiment of the present invention will be described with reference to FIG.
