  A computer that is an example of an electronic apparatus according to the first embodiment will be described in detail with reference to the drawings.

  As shown in FIGS. 1 to 3, the computer 22 of the first embodiment has a housing 24. The case 24 is a rectangular parallelepiped box-shaped member in the example illustrated in FIGS. 1 to 3.

  The housing 24 accommodates a substrate on which a processor, a control circuit, a main storage device, and the like are mounted, an auxiliary storage device, a connection terminal, and the like. Input / output devices such as a display, a keyboard, and a mouse can be connected to the connection terminal. Furthermore, the structure which is provided with the terminal for networks and can be connected to a network may be sufficient.

  In the housing 24, the front surface 24F has a rectangular shape, and for example, a connection terminal is provided. The casing 24 can be placed on the installation surface SF (see FIG. 3) so that the front surface 24F is vertically oriented, so-called vertical placement. For example, FIG. 1 shows a state in which the casing 24 is placed vertically. On the other hand, FIG.2 and FIG.3 is the state which the housing | casing 24 inclined in the width direction (arrow W direction) from the vertical state.

  Hereinafter, the vertical direction, the width direction, and the depth direction of the casing 24 mean the vertical direction, the width direction, and the depth direction when the casing 24 is placed vertically, and in the drawings, arrows U, W, and W, respectively. Shown by arrow D. In FIGS. 2 and 3, since the casing 24 is inclined, the direction indicated by the arrow W is also in a state (not parallel) with a predetermined angle with respect to the installation surface SF.

  When the housing 24 is placed vertically, the two surfaces located on the sides, ie, both sides in the width direction (arrow W direction), when viewed from the front surface 24F in the direction of arrow A1, are side surfaces 24S.

  An auxiliary leg 26 is provided in the housing 24. The auxiliary leg 26 is an example of a protruding member. In the present embodiment, two auxiliary legs 26 are provided on the entire side surface 24S, with two auxiliary legs 26 spaced apart in the depth direction (arrow D direction). As will be described later, the auxiliary legs 26 function in an auxiliary manner so as to support a part of the load of the housing 24 and suppress the falling of the housing 24 when the housing 24 is tilted.

  A rotating shaft 28 is provided on the auxiliary leg 26. The auxiliary leg 26 is attached to the housing 24 so as to be rotatable about a rotation shaft 28.

  As shown in FIG. 2, the casing 24 is provided with a base 29 extending in the vertical direction. The base 29 is a substantially U-shaped member whose horizontal cross section is open to the side surface 24S. Inside the base 29 is a housing recess 30 that houses the auxiliary leg 26. The auxiliary leg 26 moves between the accommodation position SP shown in FIG. 1 and the protruding position TP shown in FIGS. 2 and 3 by rotation about the rotation shaft 28 and movement in the vertical direction.

  The auxiliary leg 26 is in a so-called flush state in which the outer surface 26G of the auxiliary leg 26 is located on the same plane as the side surface 24S of the housing 24 at the storage position SP. On the other hand, at the protruding position TP, the lower end 26 </ b> B side of the auxiliary leg 26 protrudes from the side surface 24 </ b> S of the housing 24.

  As shown in FIGS. 4 and 5, the rotating shaft 28 has a columnar shaft body 32, and a pair of rectangular parallelepiped slide pieces 34 provided on both sides in the longitudinal direction of the shaft body 32. have.

  The housing 24 is formed with a pair of slide grooves 36 on both sides of the housing recess 30 to hold the slide piece 34 slidable in the vertical direction. The slide groove 36 is an example of a slide member.

  In a state where each of the slide pieces 34 is held in the corresponding slide groove 36, the longitudinal direction of the shaft body 32 coincides with the depth direction of the housing 24 (the direction of arrow D in FIGS. 1 and 2). In this state, when the slide piece 34 slides in the vertical direction, the shaft main body 32 also slides in the vertical direction. The slide range in the vertical direction of the shaft body 32 is limited to a range in which the slide piece 34 can slide within the slide groove 36.

  As shown in FIGS. 2 to 4, a link 38 is bridged between the auxiliary leg 26 and the housing 24. A leaf spring 40 is disposed between the housing 24 and the link 38. The leaf spring 40 is an example of a first biasing member.

  The leaf spring 40 biases the link 38 in the direction of arrow F1 (see FIG. 2). As a result, the auxiliary leg 26 receives a force in the direction of rotation from the accommodation position SP to the protruding position TP (arrow R2 direction) via the link 38. However, the auxiliary leg 26 is locked at the accommodation position SP in a normal state by a lock member 42 described later.

  When the auxiliary leg 26 is rotated from the state where the auxiliary leg 26 is in the housing position SP toward the protruding position TP around the rotation shaft 28, the rotation shaft 28 slides downward by the link 38. Compared with the structure in which the rotating shaft 28 does not slide downward, when the rotating shaft slides downward in this manner, the position of the lower end 26B of the auxiliary leg 26 at the protruding position TP is low. Note that the protruding amount of the auxiliary leg 26 from the housing 24 is limited to a predetermined range when the slide piece 34 contacts the lower end of the slide groove 36.

  Lock members 42 are provided in the housing 24 so as to correspond to the auxiliary legs 26, respectively.

  As shown in FIGS. 4, 6, and 7, the lock member 42 includes a first cylinder 44 and a second cylinder 46. In the present embodiment, the first cylinder 44 and the second cylinder 46 are formed in a cylindrical shape, and the first cylinder 44 is accommodated coaxially inside the second cylinder 46. A common center line of the first cylinder 44 and the second cylinder 46 is defined as a center line CL-1.

  In each of the first cylinder 44 and the second cylinder 46, one end portion in the axial direction is closed by the bottom plates 44B and 46B, respectively, but the other end portions are open portions 44A and 46A. In the first cylinder 44 and the second cylinder 46, the open portions 44 </ b> A and 46 </ b> A are arranged in a direction facing the upper portion of the auxiliary leg 26 in the depth direction (arrow D direction).

  Inside the first cylinder 44, a lock piece 48 is accommodated on the open portion 44A side, and a rotating body 50 is disposed on the bottom plate 44B side.

  The rotating body 50 is a cylindrical member and is disposed coaxially with the first cylinder 44. The rotating body 50 is rotatable in the direction of arrow R3 (see FIG. 7) around the center line CL-1 in the first cylinder 44.

  A weight member 52 extends downward from the rotating body 50. The weight member 52 includes an arm portion 54 that passes through the through holes 44 </ b> C and 46 </ b> C of the first cylinder 44 and the second cylinder 46, and a weight main body 56 provided at the lower end of the arm portion 54. Due to the gravity acting on the weight body 56, the rotator 50 rotates around the center line CL-1 so that the weight body 56 is positioned below.

  A predetermined gap is generated in the circumferential direction of the rotating body 50 between the through holes 44 </ b> C and 46 </ b> C and the arm portion 54. The rotating body 50 can rotate in the range of this gap.

  The lock piece 48 is a cylindrical member, and an inclined surface 58 is formed on the lower side of the distal end portion 48T facing the auxiliary leg 26.

  On the outer peripheral surface of the lock piece 48, a protrusion 60 is formed along the axial direction. The ridge 60 is accommodated in a concave groove 62 formed on the inner peripheral surface of the first cylinder 44. As a result, the lock piece 48 cannot be rotated in the direction of the arrow R3 and is guided so as to slide without play in the direction of the arrow S3. The protrusion 60 and the groove 62 are an example of a first rotation suppressing member.

  The lock piece 48 slides between the engagement position KP shown in FIG. 4 and the engagement release position RP shown in FIG. At the engagement position KP, the tip end portion 48T of the lock piece 48 is engaged with the lower side of the slide piece 34 of the rotary shaft 28, and prevents the rotary shaft 28 from sliding downward. On the other hand, the lock piece 48 releases the engagement of the slide piece 34 at the engagement release position RP, and the rotary shaft 28 is slidable downward.

  As shown in FIG. 12, when the slide piece 34 tries to rise from a state below the lock piece 48, it comes into contact with the inclined surface 58 from below. When the slide piece 34 tries to rise further in this state, the upward force applied from the slide piece 34 is converted into a force in the disengagement direction (leftward in FIG. 12) by the inclined surface 58. That is, the lock piece 48 is pushed toward the disengagement position RP by being pushed by the rising slide piece 34.

  A tension coil spring 64 is disposed between the rotary member 50 and the lock piece 48. The tension coil spring 64 applies a spring force in the direction toward the disengagement position RP (arrow F2 direction) to the lock piece 48, and is an example of a second urging member.

  A holding member 66 is provided in the first cylinder 44. The holding member 66 includes a rotating body 50, a first protrusion 66 </ b> A formed on a surface of the lock piece 48 facing the rotating body 50, and a second member formed on the surface of the rotating body 50 facing the lock piece 48. And projection 66B.

  The holding member 66 has a state in which the tip of the second protrusion 66B is in contact with the tip of the first protrusion 66A (see FIG. 8) and a state in which the second protrusion 66B is separated from the first protrusion 66A depending on the rotation angle of the rotating body 50. (See FIG. 10).

  As shown in FIG. 8, when the tip of the second protrusion 66B is in contact with the tip of the first protrusion 66A, the lock piece 48 is maintained at the engagement position KP against the spring force of the tension coil spring 64. On the other hand, as shown in FIG. 10, when the second protrusion 66B is separated from the first protrusion 66A, the lock piece 48 is moved to the engagement release position RP by the spring force of the tension coil spring 64.

  As shown in FIG. 1, the relative positions of the first protrusion 66A and the second protrusion 66B are in contact with each other at the angle of the rotating body 50 when the housing 24 is not inclined. As shown in FIG. 2, the second protrusion 66 </ b> B is set apart from the first protrusion 66 </ b> A at the angle of the rotating body 50 with the housing 24 tilted.

  In the second cylinder 46, a compression coil spring 68 is disposed between the bottom plate 44B of the first cylinder 44 and the bottom plate 46B of the second cylinder 46. The compression coil spring 68 applies a spring force to the first cylinder 44 in the direction in which the lock piece 48 moves toward the engagement position KP (the direction of the arrow F3).

  As shown in FIG. 4, the first cylinder 44 is formed with a protrusion 44 </ b> D that enters the through hole 46 </ b> C of the second cylinder 46. The protrusion 44D is opposed to the inner edge 46D of the through hole 46C of the second cylinder 46. The inner edge 46D is an edge part on the open part 46A side in the through hole 46C.

  Thereby, the movement range of the first cylinder 44 in the direction of arrow F3 is limited to a predetermined range. Specifically, when the lock piece 48 moves in the direction of arrow F2 and is in the disengagement position RP, the movement range of the first cylinder 44 in the direction of arrow F3 is such that the lock piece 48 reliably rotates the rotary shaft 28 (slide It is limited to the range where the engagement is released from the piece 34). In other words, since the first cylinder 44 does not protrude excessively in the direction of the arrow F3, a structure that can reliably disengage the lock piece 48 moved in the direction of the arrow F2 from the rotary shaft 28 (slide piece 34) is realized. The That is, the protrusion 44D is an example of a limiting member.

  On the outer peripheral surface of the first cylinder 44, a protrusion 70 is formed along the axial direction. The protrusion 70 is accommodated in a concave groove 72 formed on the inner peripheral surface of the second cylinder 46. Thus, the first cylinder 44 is not rotatable in the direction of the arrow R3 and is guided to slide in the direction of the arrow S3 without backlash. The protrusion 70 and the groove 72 are an example of a second rotation suppressing member.

  Next, the operation of this embodiment will be described.

  As shown in FIG. 1, when the vertically placed casing 24 is not tilted, the rotating body 50 takes a predetermined rotation angle by the gravity acting on the weight member 52. In this state, as shown in FIG. 8, the tip of the first projection 66A and the tip of the second projection 66B are in contact with each other. Even when the spring force of the tension coil spring 64 is received, the lock piece 48 maintains the engagement position KP. As shown in FIG. 4, since the lock piece 48 is engaged with the slide piece 34, the rotating shaft 28 does not move downward. The spring force of the leaf spring 40 acts in a protruding direction with respect to the auxiliary leg 26 via the link 38, but the slide piece 34 does not move downward, so that the auxiliary leg 26 also maintains the accommodation position.

  As shown in FIG. 2, when the vertically placed casing 24 is tilted, the rotating body 50 rotates with respect to the casing 24 due to the gravity acting on the weight member 52. In this state, as shown in FIG. 10, the second protrusion 66B is separated from the first protrusion 66A. Due to the spring force of the tension coil spring 64, the lock piece 48 moves to the disengagement position RP. As shown in FIG. 9, since the lock piece 48 is not engaged with the slide piece 34 of the rotating shaft 28, the rotating shaft 28 is slidable downward.

  In this state, the auxiliary leg 26 rotates about the rotation shaft 28 in the direction of the arrow R2 (toward the protruding position) by the spring force of the leaf spring 40 as shown in FIG. Since the link 38 is spanned between the auxiliary leg 26 and the housing 24, the rotation shaft 28 slides downward as the auxiliary leg 26 rotates.

  The sliding of the rotary shaft 28 is restricted by the slide piece 34 coming into contact with the lower end of the slide groove 36. In this state, as shown in FIG. 2, the auxiliary leg 26 is in the protruding position TP. Therefore, even if the casing 24 is tilted, the auxiliary legs 26 support the casing 24, so that the casing 24 can be prevented from falling.

  In order to return the auxiliary leg 26 from the protruding position TP to the accommodation position SP, first, the casing 24 is returned to a state where it is not inclined (vertically placed state). The rotating body 50 is rotated by the gravity acting on the weight member 52 and the tip of the first projection 66A and the tip of the second projection 66B come into contact with each other, so that the lock piece 48 moves to the engagement position KP.

  In this state, the auxiliary leg 26 is pushed from the protruding position TP to the accommodation position SP against the spring force of the leaf spring 40. Since the casing 24 and the auxiliary leg 26 are connected by the link 38, the rotating shaft 28 moves upward. Then, as shown in FIG. 12, the slide piece 34 of the rotating shaft 28 contacts the inclined surface 58 of the lock piece 48.

  When the auxiliary leg 26 is further pushed to the accommodation position SP, the slide piece 34 pushes the lock piece 48 upward. The inclined surface 58 converts the upward force acting from the slide piece 34 into a force in the disengagement direction. For this reason, the lock piece 48, the rotating body 50, and the first cylinder 44 move in the disengagement direction against the spring force of the compression coil spring 68. Then, as shown in FIG. 13, when the lock piece 48 is retracted from the slide range of the slide piece 34, the slide piece 34 slides upward from the lock piece 48.

  As shown in FIG. 14, when the slide piece 34 is positioned above the lock piece 48, the lock piece 48, the rotating body 50, and the first cylinder 44 move in the direction of arrow F <b> 3 by the spring force of the compression coil spring 68. Then, the lock piece 48 reaches the engagement position KP.

  In this embodiment, as can be seen from the above description, when the auxiliary leg 26 is moved from the accommodation position SP to the protruding position TP, the auxiliary leg 26 is moved to the protruding position TP by the spring force of the leaf spring 40 (an example of a biasing member). ing. For example, as compared with a structure in which the auxiliary leg 26 is moved to the protruding position by gravity acting on the auxiliary leg, the auxiliary leg 26 is surely moved to the protruding position TP in a short time, so that the effect of suppressing the fall of the casing 24 is high.

  In addition, the auxiliary leg 26 reliably takes the protruding position TP when the housing 24 is inclined. Thus, since the effect of suppressing the fall of the casing 24 is not left to the judgment of the user of the computer 22, the fall of the casing 24 can be reliably suppressed.

  In a state where the auxiliary leg 26 is in the accommodation position SP, the auxiliary leg 26 does not protrude from the housing 24. Therefore, the auxiliary leg 26 does not get in the way, and the use environment of the computer 22 is good.

  The auxiliary leg 26 is maintained attached to the housing 24 by the rotation shaft 28 and the link 38. For example, when the casing 24 is used in a vertical position, it is not necessary to attach the auxiliary legs 26 to the casing 24, and the work load when using the computer 22 does not increase.

  The auxiliary leg 26 is rotatably attached to the housing 24 by a rotation shaft 28. That is, the auxiliary leg 26 can be moved between the accommodation position SP and the protruding position TP with a simple structure by rotating around the rotation shaft 28.

  The rotating shaft 28 slides in the vertical direction of the casing 24 placed vertically. When the auxiliary leg 26 is at the protruding position TP, the auxiliary leg 26 is also moved downward by sliding the rotating shaft 28 downward. Since the lower end of the auxiliary leg 26, that is, the portion that supports the load of the inclined casing 24 is located below, the load of the casing 24 can be supported by the auxiliary leg 26 with the inclination angle of the casing 24 being small.

  A link 38 is spanned between the housing 24 and the auxiliary leg 26. Therefore, the rotary shaft 28 can be moved downward when the auxiliary leg 26 moves to the protruding position TP. In other words, it is possible to realize a structure in which the auxiliary leg 26 moves to the protruding position TP as the rotary shaft 28 moves downward.

  In the present embodiment, the leaf spring 40 is used as an example of the urging member. That is, the auxiliary leg 26 can be moved from the housing position SP to the protruding position TP with a simple structure using the leaf spring 40 without using a drive source such as a motor or an actuator.

  The leaf spring 40 may be bridged between the casing 24 and the auxiliary leg 26, but in the above embodiment, it is bridged between the casing 24 and the link 38. Since the end portion 24 </ b> A (see FIG. 11) on the housing 24 side of the link 38 does not slide with respect to the housing 24, the attachment state of the leaf spring 40 to the link 38 is stabilized.

  The lock member 42 may lock the auxiliary leg 26 itself in a state where the auxiliary leg 26 is in the accommodation position SP. However, in this embodiment, the locking leg 42 prevents the downward movement of the rotary shaft 28, thereby preventing the auxiliary leg 26. 26 is locked at the storage position SP. Since the locking member 42 does not directly lock the auxiliary leg 26, the influence on the shape and moving range of the auxiliary leg 26 is small, and the degree of freedom of the shape and moving range of the auxiliary leg 26 is high.

  The lock member 42 has a lock piece 48 that can move between the engagement position KP and the engagement release position RP. When the lock piece 48 moves to the engagement release position RP, the lock of the rotary shaft 28 by the lock member 42 can be released. Although the lock piece 48 is biased to the disengagement position by the tension coil spring 64, the lock piece 48 can be maintained at the engagement position KP by the holding member 66. When the holding of the lock piece 48 by the holding member 66 is released, the lock piece 48 can be reliably moved to the engagement release position RP by the spring force of the tension coil spring 64.

  The holding member 66 includes a rotating body 50, a first protrusion 66 </ b> A formed on the lock piece, and a second protrusion 66 </ b> B formed on the rotating body 50. Substantially, if two protrusions are formed on the rotating body 50 and the lock piece 48, the lock piece 48 can be held and released at the engagement position KP, and the structure is simple. Further, by rotating the rotating body 50, the lock piece 48 can be held and released from the engagement position KP, and a complicated mechanism does not have to be used.

  The lock piece 48, the tension coil spring 64, and the rotating body 50 are accommodated in the first cylinder 44. That is, the lock piece 48, the tension coil spring 64, and the rotating body 50 can be integrally held by the first cylinder 44.

  A protrusion 60 is formed on the lock piece 48, and this protrusion 60 is engaged with the concave groove 62 of the first cylinder 44. Thereby, it can suppress that the lock piece 48 rotates with respect to the 1st cylinder 44 in the circumferential direction. Further, the lock piece 48 can be guided so as to move without play between the engagement position KP and the engagement release position RP.

  The first cylinder 44 is biased in the direction of arrow F3 (see FIG. 7) by the spring force of the compression coil spring 68. The arrow F3 direction is a direction in which the lock piece 48 moves to the engagement position KP. That is, the lock piece 48 can be reliably moved to the engagement position KP by the spring force of the compression coil spring 68.

  Moreover, the movement range of the first cylinder 44 that receives the spring force of the compression coil spring 68 is such that when the lock piece 48 is in the disengagement position RP, the lock piece 48 is reliably engaged from the rotary shaft 28 (slide piece 34). Limited to the range to be released. Therefore, the lock piece 48 can be reliably separated from the slide piece 34 by returning the auxiliary leg 26 from the protruding position TP to the accommodation position SP.

  The first cylinder 44 and the compression coil spring 68 are accommodated in the second cylinder 46. That is, the first cylinder 44 and the compression coil spring 68 can be integrally held by the second cylinder 46.

  A protrusion 70 is formed on the first cylinder 44, and the protrusion 70 is engaged with the concave groove 72 of the second cylinder 46. Thereby, it can suppress that the 1st cylinder 44 rotates with respect to the 2nd cylinder 46 in the circumferential direction (arrow R3 direction of FIG. 6). Further, the first cylinder 44 can be guided so as to move in the direction of the arrow axis (the direction of the arrow S3 in FIG. 6) without rattling.

  The lock piece 48 is formed with an inclined surface 58. Thereby, the lock piece 48 can be moved to the disengagement position RP using the force acting on the lock piece 48 from the slide piece 34 moving upward. The lock piece 48 can be moved to the disengagement position RP by the operation of moving the auxiliary leg 26 from the protruding position TP to the accommodation position SP, and the operability is excellent.

  In the above embodiment, the casing 24 has a rectangular parallelepiped box shape. For this reason, when the casing 24 is placed vertically, the casing 24 becomes vertically long, that is, a posture that is longer in the vertical direction than in the horizontal direction, so that it is easy to fall down. Since the auxiliary leg 26 is provided on the side surface 24S located on the side when the casing 24 is placed vertically, the auxiliary leg 26 can be prevented from being overturned in the vertically placed state.

  In addition, as a structure for moving the auxiliary leg between the housing position and the protruding position with respect to the housing 24, a structure other than the above embodiment can be adopted. For example, a structure in which the auxiliary leg is rotated by a vertical rotation axis in a vertically placed housing may be used. In this structure, the auxiliary leg rotates in the horizontal direction with respect to the vertically placed housing, and moves between the housing position and the protruding position.

  In addition, in a vertically placed housing, the auxiliary leg may slide in the horizontal direction to move between the storage position and the protruding position.

  In the above description, the computer 22 having the housing 24 is described as an example of the electronic device, but the electronic device is not limited thereto. For example, the electronic device may be an external storage device, a display, a speaker, or the like. Furthermore, the electronic device may be a server rack on which one or a plurality of servers are mounted.

  The embodiments of the technology disclosed in the present application have been described above. However, the technology disclosed in the present application is not limited to the above, and can be variously modified and implemented in a range not departing from the gist of the present invention. Of course.
