DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As an embodiment of an information processing apparatus according to the present invention, an application example to a small-type word processor or a personal computer will be described below with reference to the drawings.
FIGS. 1 to 3 are perspective views showing a form in which a display screen is rotated vertically and horizontally from a landscape orientation to a portrait orientation in a text creation device such as a word processor. Various input keys 11 for creating texts and figures are provided as standard on the upper surface key input section of the device main body 10, and are stored by closing the device main body 10 from above with a display case 30, which is a display case according to the present invention. A relatively small model called a laptop or notebook which sometimes protects the input key 11 is shown. The display case 30 has, for example, a built-in liquid crystal display (LCD) or the like, and has a display screen 31 on the front side for displaying input images of texts and figures. The apparatus may be of a printer-integrated type in which a printing device 12 is arranged at the rear of the device main body 10.

[0007] A pair of bearings provided on both sides of the input key 11 of the main body 10 are provided with a bracket 20 as a support member according to the present invention.
1, 21 are pivotally supported and are connected in such a manner that the butterfly can be opened freely. The display case 30 is supported on the front side of the bracket 20 and moves from the horizontal position at the first fixed position shown in FIG. 1 to the vertical position at the second fixed position shown in FIG.
Can be turned around. Moreover, the bracket 20
Is operated to open the butterfly with respect to the device main body 10, so that the display case 30 functions as a lid member to close and protect the input key 11 with this operation.

FIG. 5 is a rear view of FIG. 1 showing a state where the display case 30 is in the first fixed position in the horizontal position, and FIG. 6 is directed from the first fixed position to the second fixed position. FIG. 7 shows a rear view of FIG. 2 in the middle of turning, and FIG. 7 shows a rear view of FIG. 3 in a second fixed position in the vertical posture. As shown in the drawings, in the present embodiment, a plurality of turning shafts referred to in the present invention are provided on the display case 30 side, and a plurality of guide grooves corresponding thereto are provided on the flat bracket 20 side. Further, the number of the rotation support shafts can be any of a two-axis configuration using two rotation support shafts and a three-axis configuration using three rotation support shafts. Hereinafter, the display rotation mechanism using the three-axis configuration will be described in detail.

In the bracket 20 formed in a flat shape,
A first guide groove 22 extending in the horizontal and horizontal directions of the device, a second guide groove 23 which is curved with a predetermined curvature R and extends obliquely upward, and in a vertical and vertical direction of the device in a direction perpendicular to the first guide groove 22. Extending third guide grooves 24 are respectively formed. The shape and arrangement position of these first to third guide grooves 22 to 24 are such that the display case 30 moves from the horizontal posture (first fixed position) to the vertical posture (second fixed position).
Alternatively, it is formed so as to correspond to a trajectory that turns vertically and horizontally in the opposite direction. In the case of the first guide groove 22, the first turning support shaft 32 described below operates by drawing a trajectory by linear reciprocating movement in the left-right direction in the drawing, so that it can be guided to cope with the vertical and horizontal turning of the display case 30. It is formed by the groove length L _1. In the case of the second guide groove 23, the second turning support shaft 3
3 guide the are formed with a curvature R and the arcuate groove length L ₂ may correspond to vertical and horizontal turning of the display case 30. In the case of the third guide groove 24, since the third turning support shaft 34 operates by drawing a trajectory by reciprocating motion in the vertical and vertical directions in the figure, the third turning groove 34 can guide the third turning groove 34 to cope with the vertical and horizontal turning of the display case 30. It is formed with a length L _3.

A display case 30 is supported on the flat front side of the bracket 20, and as shown in FIGS.
The first to first guides which are engaged with and guided by the third guide grooves 22 to 24.
Third turning support shafts 32 to 34 are provided to protrude. The inter-axis distance of each rotation support shaft is set to P ₁ and P ₂ .

As shown in FIG. 8, which is a rear view of the bracket 20, the first to third turning support shafts 32 to 34 engaged with the first to third guide grooves 22 to 24 have the same structure as shown in FIGS. As shown in FIG. 11, the flange-shaped flange members 25, 26, and 44 having diameters sufficiently larger than the widths of the respective guide grooves are formed by the stopper screws 2.
7, 28, 45 (see FIG. 5), and the first to third turning shafts 32 to 3 are connected by the flange members 24, 25, 44.
4 is prevented from dropping from the first to third guide grooves 22 to 24.

The third guide groove 24 and the third
In the third axis portion composed of the turning support shaft 34, the movable rod 40 shown in FIG.
Is arranged. The movable rod 40 has a spring guide portion 41 extending in a straight bar shape, and the spring guide portion 41 is inserted into a through hole 24 a (see FIG. 13) provided at the lower end of the third guide groove 24 so as to be vertically Sliding in the direction is possible. The upper end of the movable rod 40 is a push-up portion 42 having a concave surface 43 so that the movable rod 40 can contact the third rotation support shaft 34 from below. Since the above-mentioned flange-like flange 44 is connected to the third turning support shaft 34 with the stop screw 45, the upper end pushing-up portion 42 of the movable rod 40 is covered from above, so that it can be prevented from falling off from the third guide groove 24. It has become.

As is apparent from FIGS. 13 and subsequent figures, a coil spring 47 as an elastic member, which is a gist of the present invention, is elastically attached around the axis of the movable rod 40.
The movable rod 40 is moved from the compressed state shown in FIG.
4 is urged in the direction of pushing up. In other words, at the first fixed position in FIG. 13 in which the display screen 31 of the display case 30 is in the horizontal posture, the movable rod 40 is pushed up to move the display case 30 through the third rotation support shaft 34.
Is biased in a direction of turning toward the second fixed position in the vertical posture. Further, at the second fixed position where the movable rod 40 has reciprocated up and down, the coil spring 47 is compressed again as shown in FIG. That is, the coil spring 47 urges the display case 30 to rotate from the horizontal posture (the first fixed position) to the vertical posture (the second fixed position) via the movable rod 40, and conversely, the vertical posture (the second fixed position). From the horizontal position (the first fixed position), which is the original return position.

Further, in the embodiment, the display case 30 has a click sensation at the positions where the display case 30 reaches the horizontal position and the vertical position, respectively, with the vertical movement of the movable rod 40. A possible elastic part 48 is provided, and a convex part 49 is provided so as to protrude from the outer surface of the elastic part 48. The bracket 20 is provided with a pair of concave members 29, 29 to which the convex portions 49 are engaged and disengaged, which are fixed on both sides of the third guide groove 24 with a set screw 29 a.

In addition to the above configuration, although not shown, the display case 30 is positioned and locked with respect to the bracket 20 in a horizontal position (first fixed position) or a vertical position (second fixed position). Lock means can be provided. Further, as a positioning structure at both lock positions, a stopper 39 is formed on the back surface of the display case 30 so as to protrude therefrom as shown in FIGS. At the upper end of the bracket 20. Further, switching from the horizontal position to the vertical position (second fixed position)
, A switching circuit can be provided to switch the input format of the display screen 31 from the landscape display mode to the portrait display mode or vice versa each time the switching is performed.

With the above configuration, the information processing apparatus according to the embodiment operates as follows. As shown in FIGS. 1 and 5, when the display screen 31 is in the landscape orientation, the display case 30 is locked so as to prevent turning. The lock is released, and the display case 30 is rotated by manual operation, for example, clockwise as shown in FIG. That is, as shown in FIG. 5, when the display case 30 is in the locked state, the stopper 39 on the rear surface is in contact with the upper end locking recess 20a of the bracket 20 and is held at the first fixed position in the horizontal posture. In this locked state, the movable rod 40 is
The third turning support shaft 34 on the side is pressed down in a compressed state against the coil spring 47 (FIG. 13).
reference).

When the lock of the display case 30 is released, the movable rod 40 is pushed up by the elastic extension force of the coil spring 47 and pushes up the third turning support shaft 34 on the display case 30 side, thereby moving the display case 30 clockwise. (In the counterclockwise direction in FIG. 5 as viewed from the rear) and flip up with an appropriate force to rotate. The turning by the flip-up is an initial operation, which reduces the burden of starting the turning by manually operating the display case 30 and assisting the initial turning force (hop-up operation). Subsequently, when the display case 30 is turned, as shown in FIG.
Is guided from the left to the right in the figure the direction to move the groove length L ₁ by 2, groove length obliquely upward-sloping second turning shaft 33 is guided by the second guide groove 23 curved Figure L Move ₂

As shown in FIGS. 3 and 7, when the display case 30 is turned by 90 ° to reach the second fixed position in which the display screen 31 is in the vertical posture, the movable rod 40 which has reciprocated up and down once at this stage is a coil spring. The coil spring 47 is pressed down again by the third turning support shaft 34 in a state in which the coil spring 47 is compressed (see FIG. 15). This second
The display case 30 is positioned by the lock means even in the home position.

On the other hand, when returning the display case 30 in the locked state at the second fixed position in the vertical position to the first fixed position in the horizontal position again, when the lock is released, the display case 30 is moved to the third turning support shaft 34 at that moment. Is pushed down by the elastic extension force of the coil spring 47 via the. The turning operation for returning the display case 30 to the first fixed position is performed in exactly the same procedure as described above. At the moment when the display case 30 is in the horizontal position of the first fixed position, the descent impulse including the weight of the display case 30 is added. The coil spring 47 is buffered by compression (FIGS. 5 and 1).
3). The same applies to the buffering action of the coil spring 47 even at the moment of reaching the vertical position.

From the first fixed position in the horizontal position to the second position in the vertical position
At the time of the turning operation to the home position or the reverse direction, the sense of positioning the display case 30 at each home position is determined when the projection 49 on the outer periphery of the flanged flange 44 engages with the recess 29 on the bracket 20 side. It can be recognized with an elastic click feeling.

As the information processing apparatus of the present invention, a series of operations from the first fixed position in the horizontal position of the display case 30 to the second fixed position in the vertical position is performed by the first to third turning supports as in the embodiment. A turning locus based on three axes 32 to 34 is a basic configuration. However, as described above, this can also be achieved with a two-axis configuration. However, when the display case 30 is manually operated with a three-axis turning locus, a very smooth turning operation with respect to the bracket 20 can be obtained. It is superior to two axes, such as the freedom of installing the mechanism of the hop-up operation (two axes is also possible) that helps reduce the burden of the initial turning force by using one of the above Has been established by the inventors. However, even in the case of two axes, if an elastic member such as the coil spring 47 acts on one of the axes, an appropriate braking action acts on the operation of the display case 30 during vertical and horizontal rotation, and furthermore, The operability can be improved by, for example, assisting the turning force.

In the case of the present invention, as in the embodiment, the display case 30 serves as the
The desktop type of a relatively large model in which the display case shifts from a horizontal position to a vertical position with respect to a bracket fixed to the device main body, without being limited to a laptop type in which the device main body 10 is closed by a hinge connection of 0. Application to is also possible.

[0023]

As described above, in the information processing apparatus according to the present invention, the operation of turning the display case (display case) from the horizontal position to the vertical position or the opposite direction with respect to the support member (bracket) is performed. For example, the trajectory operation by the three-axis configuration of the first to third rotation support shafts and the smooth operation are performed by the support of the rotation of the elastic member to the coil spring and the like, so that the operability can be remarkably improved, and the rotation of the display screen can be achieved. It is effective for OA equipment such as a word processor or a personal computer having a mechanism.
