The terminal 40 protrudes from the bottom surface 36a while being elastically supported so as to be able to advance and retreat, and has a structure that can be connected (contacted) to the terminal plate 23 regardless of the angle of the tablet 14 that is erected. The terminal 40 is, for example, a terminal for supplying power, and supplies a current from a battery (not shown) mounted on the unit 12 or a power plug connected to the unit 12 to the tablet 14. The terminal 40 may be a USB terminal that can transmit and receive signals simultaneously with power supply.

  As shown in FIG. 3, the angle setting mechanism 34 includes an angle defining member 42 that protrudes forward and backward from the rear wall surface of the groove 36, a detection member 44 that protrudes forward and backward from the bottom surface 36 a of the groove 36, and a detection member 44. And a locking member 46 that permits or prohibits (locks) the forward and backward movement of the angle defining member 42 by operating in conjunction with each other. A pair of angle setting mechanisms 34 are provided, for example, and are provided in the vicinity of both left and right ends of the groove 36 (see FIG. 1).

  The angle defining member 42 is a plate-like structure having a certain width (see also FIG. 1). The angle defining member 42 includes a front-end support portion 42a that advances and retreats in the groove portion 36, a spring attachment portion 42b provided at the rear end, and a rack gear portion 42c formed on the lower surface between the support portion 42a and the spring attachment portion 42b. And have.

  The front end surface of the support portion 42 a is a support surface that supports the back surface of the tablet 14 placed on the placement portion 30. An inclined surface 42d that is gradually inclined toward the tip is formed on the upper surface of the support portion 42a.

  The spring attachment portion 42b is a portion to which the other end of the coil spring 48 having one end fixed to the device housing 26 is attached. The coil spring 48 is a tension spring that constantly urges the angle defining member 42 forward with respect to the device housing 26, that is, in a direction in which the support portion 42 a advances forward in the groove portion 36. Accordingly, the angle defining member 42 is always set to a position where the angle defining member 42 has always advanced forward in the groove 36 by the urging force of the coil spring 48, and is elastically supported so as to be able to advance and retreat relative to the device housing 26. Thereby, the angle definition member 42 can advance and retreat toward the back surface of the tablet 14 placed on the placement unit 30, and can move backward when pressed against the back surface of the tablet 14 (FIG. 3). To FIG. 5).

  The rack gear portion 42c is formed by continuously forming teeth on the lower surface of the angle defining member 42 along the front-rear direction. Each tooth of the rack gear portion 42c can mesh with an engaging portion 50 of a lock member 46 described later. The rack gear portion 42c may be configured by a structure other than the continuously formed teeth (unevenness), for example, a plurality of slits.

  The detection member 44 is a cylindrical pin that is provided on the front end side of the lock member 46 and can be projected and retracted into the groove portion 36, and can detect whether or not the tablet 14 is placed on the placement portion 30. In a state where the tablet 14 is not placed on the placement portion 30, the detection member 44 is in a position protruding upward from the bottom surface 36a of the groove portion 36 as shown in FIG. On the other hand, when the tablet 14 is placed on the placement portion 30, the detection member 44 is moved down by its own weight as shown in FIGS. To work.

  The lock member 46 is a rod-shaped member having a substantially L-shaped side surface shape, and is pivotally supported with respect to the device housing 26 by a rotation shaft 52 provided at a substantially center of the horizontal portion. At the front end of the horizontal portion of the lock member 46, a detection member 44 is provided in a substantially orthogonal posture. The rear end side of the lock member 46 is an engaging portion 50 that protrudes upward, and its tip has a tapered shape that can engage with any tooth of the rack gear portion 42 c of the angle defining member 42. A torsion coil spring 54 is externally attached to the rotating shaft 52. Due to the biasing force of the torsion coil spring 54, the lock member 46 is always biased counterclockwise in FIG. 3, that is, in the direction in which the detecting member 44 advances into the groove 36 and the engaging portion 50 moves away from the rack gear portion 42c. Has been.

  Next, the operation when the tablet 14 is held in a standing posture at a predetermined angle by the stand mechanism 10 will be described with reference to FIGS.

  In a state where the tablet 14 is not stood on the stand mechanism 10, the angle defining member 42 is at the most advanced position in the groove 36 by the biasing force of the coil spring 48 as shown in FIG. The detection member 44 is in a position protruding into the groove 36 by the urging force. For this reason, the engaging part 50 of the lock member 46 is in a position separated from the rack gear part 42c, and the angle defining member 42 is in a freely movable state.

  When the tablet 14 is raised by the stand mechanism 10, the tablet 14 is gripped with the mounting surface 18 a facing down, and the tablet 14 is inserted and placed in the groove portion 36 with a desired standing angle. At the same time, the positioning hole 22 of the tablet 14 is fitted into the positioning protrusion 38 protruding from the bottom surface 36 a, and the terminal plate 23 is brought into contact with the terminal 40.

  For example, as shown in FIG. 4, when the tablet 14 is placed in the groove 36 at an upright angle that rises close to 90 degrees, the angle defining member 42 does not retreat without receiving a pressing force from the tablet 14. Alternatively, the detection member 44 is pushed by the mounting surface 18a of the tablet 14 in a slightly retracted state after being received slightly. Then, the lock member 46 is rotated clockwise around the rotation shaft 52 against the urging force of the torsion coil spring 54 by the detection member 44 moved downward by its own weight, and the engagement portion 50 is moved upward. And meshes with the rack gear portion 42c.

  As a result, the advancing / retreating position of the angle defining member 42 is fixed by the engaging portion 50 of the lock member 46, so that the angle defining member 42 moves the back surface of the tablet 14 at an upright angle of about 90 degrees by the support portion 42 a at the tip. The tablet 14 can be reliably supported, and the tablet 14 is held at the standing angle shown in FIG. At this time, the fitting action of the positioning projection 38 and the positioning hole 22 more reliably regulates the lower edge portion of the tablet 14 from coming out forward of the groove portion 36, and the stability of the tablet 14 is further enhanced. ing.

  Further, for example, as shown in FIG. 5, when the tablet 14 is placed in the groove 36 with the standing angle laid back about 120 degrees, the angle defining member 42 receives the pressing force from the tablet 14 and becomes large. In this state, the detection member 44 is pressed by the mounting surface 18a of the tablet 14. Then, the engaging portion 50 moves upward and meshes with the rack gear portion 42c.

  As a result, the advancing / retreating position of the angle defining member 42 is fixed by the engaging portion 50 of the lock member 46, so that the angle defining member 42 moves the back surface of the tablet 14 at an upright angle of about 120 degrees by the support portion 42 a at the tip. The tablet 14 can be reliably supported, and the tablet 14 is held at the standing angle shown in FIG. Also at this time, the lower edge portion of the tablet 14 is more reliably restricted from moving forward of the groove portion 36 by the fitting action of the positioning protrusion 38 and the positioning hole 22.

  An inclined surface 42d is formed on the upper surface of the support portion 42a of the angle defining member 42. Therefore, even when the mounting surface 18a of the tablet 14 comes into contact with the angle defining member 42 when the tablet 14 is inserted into the groove 36, the mounting surface 18a slides on the inclined surface 42d and retreats. Move. For this reason, it is avoided that the tablet 14 is hooked on the upper surface of the angle defining member 42, and the tablet 14 can be smoothly inserted into the groove 36.

  On the other hand, when removing the tablet 14 from the stand mechanism 10, the tablet 14 may be extracted upward from the groove 36. As a result, the detection member 44 released from the weight of the tablet 14 advances into the groove 36 by the biasing force of the torsion coil spring 54, and the engaging portion 50 is separated from the rack gear portion 42c. Therefore, the angle defining member 42 also advances into the groove 36 by the urging force of the torsion coil spring 54, and the stand mechanism 10 returns to the standby state shown in FIG.

As a result, the stand mechanism 10 (10A) can be used under a wide range of usage conditions, and its versatility and convenience are improved.

  In this case, in the stand mechanism 10 according to the first embodiment, the placement unit 30 has a groove 36 that receives the lower edge of the tablet 14, and the angle setting mechanism 34 is placed on the placement unit 30. An angle defining member 42 that is elastically supported so as to be able to advance and retreat toward the back surface of the tablet 14 and can support the back surface of the tablet 14 by the support portion 42a at the tip portion, and protrudes from the bottom surface 36a of the groove portion 36 so as to be capable of advancing and retreating. And a detection member 44 that is pressed and retracted by the tablet 14 disposed at 36, and a lock member 46 that locks the advancing / retreating position of the angle defining member 42 in conjunction with the retraction of the detection member 44.

  In the stand mechanism 10 </ b> A according to the second embodiment, the mounting portion 60 is provided with a groove portion 66 that receives the lower edge portion of the tablet 14, and rotates within a predetermined angle range by the rotation shaft 70 with respect to the device housing 26. The angle setting mechanism 62 includes a guide portion 72 that elastically supports the holding tray 68 so as to move up and down in a state where the holding tray 68 is urged upward, and the holding tray 68 is provided on the tablet 14. A lock portion 76 that meshes with a gear body 74 provided on the lower surface side of the holding tray 68 and locks the rotation position of the holding tray 68 when pressed by its own weight.

  Therefore, according to these stand mechanisms 10 (10A), the tablet 14 can be held at a desired standing angle with a structure using a simple mechanical mechanism, compared with the case where a complicated mechanical mechanism or control mechanism is used. Thus, it is possible to reduce the size, weight and cost. In this case, in the stand mechanism 10 (10A), the tablet 14 can be raised at a plurality of standing angles corresponding to the number of teeth provided in the rack gear portion 42c (the gear body 74). For this reason, if the number of teeth provided in the rack gear portion 42c (the gear body 74) is changed according to the specifications of the stand mechanism 10 (10A), the settable number of standing angles can be easily changed.

  Also, in such an electronic device (information device set) composed of the tablet 14 and the unit 12 having the stand mechanism 10 (10A), the tablet 14 is turned over when stored or carried, and the display 16 faces the keyboard 24. It is set on the upper surface of the unit 12 as a horizontal posture to be in a closed mode in which the mounting surface 18a is mounted on the attachable / detachable surface 28a of the projecting portion 28 (see the tablet 14b indicated by a two-dot chain line in FIG. 1). Thereby, the tablet 16 and the unit 12 can be integrated in a closed state without exposing the display 16 and the keyboard 24 to the outside, and the information device set can be easily carried. Here, when the tablet 14 is turned upside down to expose the display 16 on the surface, the tablet mode is set, and the tablet 14 can be used while being attached to the unit 12. On the other hand, when the tablet 14 is made to stand at a desired standing angle by the stand mechanism 10 (10A), the notebook mode is set (see the tablet 14a indicated by a two-dot chain line in FIG. 1). Thereby, the keyboard 24 can function effectively as an input means of the tablet 14, and the information device set can be used in the same manner as a general notebook PC.
