JP 2000-124620 A.

As shown in FIGS. 2 to 6 , the conventional “electronic device with a display” includes a display unit 12 whose one end is pivotally supported by a housing 11 and a sliding surface provided on the display unit 12. 12c, 12d and a brake piece 13 fixed to the housing 11 and pressed against the sliding surfaces 12c, 12d. When the display unit 12 is tilted about the support shaft 11a , the sliding surface 12c, the friction caused by 12d and friction braking members 13, the display unit 12 is configured to be tilted in a stable operation.

The sliding surface 12c formed by two concentric arcs, to form a non-braking portion 12e by expanding 12d partially, the angle at which the display unit 12 does not require a braking force, the non-braking portion 12e This releases the braking force.

Then, in the non-braking portion 12e of the display unit 12, by engaging the fixing claw 11b projecting from from the housing 11 to the fixing claw 12f of the display unit 12 side with respect to the housing 11 so that the display unit 12 is not rattle The display unit 12 is fixed.

  In recent years, electronic devices of this type tend to be smaller in size, and the display means tend to be larger in order to display more information or to make information easier to see.

When a large display means is attached to a housing of a downsized electronic device, a part of the display means protrudes from the housing. As in this for the electronic apparatus equipped with a conventional display device, non-in brake unit 12e of the display unit 12 by the fixing claw 11b which was so fixed to the housing 11, fixing claws on the housing 11 side of the display unit 12 The space for installing 11b cannot be secured, or the fixing claw 11b can be provided only in the vicinity of the shaft support portion of the display unit 12 .

However, the display unit 12 during non-braking of the display unit 12 can not be fixed to the housing 11, or move the housing 11 during use of electronic devices, when used over an electronic device to a wall, the display unit 12 is rattling There are problems such as loss of luxury.

Further, when the fixing claw 11b for fixing the display unit 12 is provided in the vicinity of the shaft support portion, a large holding force cannot be obtained for the fixing claw 11b. Therefore, in an electronic device using the large display unit 12 in particular, the display unit 12 There is a problem that it cannot be fixed securely.

  The present invention has been made in order to improve such a conventional problem, and an object of the present invention is to provide an electronic device in which the display means can be securely fixed in the storage position.

The electronic device according to the present invention includes a display means pivotally attached to a casing so as to be mounted in a standing position and a storage position, and a sliding surface provided on a rotating portion of the display means. A pair of concentric arc-shaped ribs to be formed, and a guide groove between the pair of arc-shaped ribs, both ends of which are closed by stoppers, and which fits a brake provided on the housing side when provided in an arc-like rib of the inner side of the pair of arcuate ribs, and the locking portion protruding locking the sliding of the brake shoe when the display means it is turned in the storage position, the locking A brake notch that cuts out a part of the arc-shaped rib outside the pair of arc-shaped ribs at a position substantially opposite to the portion, and the brake element fitted into the guide groove by the notch is the display When the means is rotated to the storage position, it slides on the sliding surface of the arc-shaped rib. When the brake member moves over the locking portion and the display means reaches the storage position, the sliding surface of the inner arc-shaped rib, the stopper, and the locking are generated. The movement is restricted by contacting the outer peripheral surface of the brake element at three points with the portion .

With this configuration, when the display means is in the storage position, the brake means is locked by the three points of the sliding surface, the stopper, and the locking portion, and the display means is not rattled, so that the sense of quality may be impaired. In addition, since the locking portion is provided on the sliding surface, there is no need to provide a fixing means such as a fixing claw at a position away from the pivoting portion of the display means. Even if the electronic device partially protrudes from the housing, the display means stored in the storage position can be securely fixed.

In addition , since appropriate friction is obtained in the display means by the friction between the braking element sliding on the sliding surface and the sliding surface, the display means can be smoothly tilted, and the display means is displayed after adjusting the angle to an easy-to-see position. Even if the hand is released from the means, the display means is held at the adjustment position by the frictional force of the sliding surface and the brake, so that the angle of the display means does not change into a flood.

  Further, since the brake element can be inserted between the sliding portions from the notch portion formed at the position facing the locking portion, the display means can be easily assembled.

  The electronic device according to the present invention is such that the braking element is formed of an elastic body, and the braking element is attached to the support rod by being inserted from the distal end side of the tapered supporting rod having a gradually increasing diameter on the distal end side. .

  With such a configuration, the brake element can be attached by press-fitting the brake element from the front end of the support rod, so that the assembling work is facilitated and there is no fear of the brake element dropping off from the support rod.

  In the electronic device of the present invention, a support rod for supporting the brake element is provided by protruding from an elastic rib having elasticity in the axial direction of the support rod.

  With this configuration, the elastic rib is elastically deformed when the brake element gets over the engaging part, and the brake element easily gets over the engaging part, so that the operability is improved and the brake element is worn or damaged early. Since it does not do, durability is also improved.

In the electronic device of the present invention, when the display means is in the storage position, the brake means is locked by the three points of the sliding surface, the stopper, and the locking portion, and the display means is not rattled. Since the locking portion is provided on the sliding surface, it is not necessary to provide a fixing means such as a fixing claw at a position away from the pivoting portion of the display means. Even in the case of an electronic device in which a part of the display means protrudes larger than the housing, the display means stored in the storage position can be securely fixed.

  Embodiments of the present invention will be described in detail with reference to the drawings.

It is an operation explanatory view.

  The electronic device shown in FIG. 1 has a housing 1 formed of synthetic resin.

  The case 1 is composed of an upper case 1a and a lower case 1b. An operation panel 1c having a plurality of push buttons 2 on the upper surface of the upper case 1a, and a handset placed on the side of the operation panel 1c. A portion 1d is provided, and the handset 3 is detachably placed on the handset placement portion 1d.

  An antenna 5 for wireless communication with a slave unit (not shown) is rotatably attached to the side surface of the housing 1 opposite to the handset placement unit 1d. At the rear of the operation panel 1c, a display means mounting portion 1f is formed by recessing the upper surface of the upper housing 1a.

  As shown in FIG. 2, the display means mounting portion 1f is surrounded on three sides by a front wall 1g and both side walls 1h, and a pair of pins 1i is located on the upper side of both side walls 1h at a position close to the front wall 1g. Are projecting horizontally so as to face each other, and the display means 4 is pivotally attached to these pins 1i.

  The display means 4 has a case 4a that is substantially equal to the width of the display means mounting portion 1f and has a depth that is almost twice as long, and displays various information such as numbers, symbols, and images on the front surface of the case 4a. A display panel 4b made of a liquid crystal display or the like is attached, and various function buttons 4c are provided on the lower side of the display panel 4b.

  The case 4a of the display means 4 is composed of an upper case 4d and a lower case 4e formed of synthetic resin, and pin holes 4f drilled on both lower sides of the upper case 4d are on both sides of the display means mounting portion 1f. It is fitted to a pin 1i projecting from the wall 1h, so that the upper part of the display means 4 protruding rearward from the display means mounting portion 1f can be tilted up and down around the pin 1i. It has become.

  Further, a braking member 6a of the braking means 6 that generates friction when the display means 4 is tilted protrudes from the back surface of the lower case 4e.

  As shown in FIG. 3, the braking member 6a is formed of a plate having a substantially half-moon shape, and a pair of concentric arc-shaped ribs 6c and 6d centering on the pin 1i project from the side surface of the braking member 6a. The opposing surfaces of the arc-shaped ribs 6c and 6d are sliding surfaces 6e, and a guide groove 6f is formed between the arc-shaped ribs 6c and 6d. In addition, a brake element 6j provided on the housing 1 side is fitted.

  Both end sides of the guide groove 6f are closed by stoppers 6g and 6h connecting the ends of the arc-shaped ribs 6c and 6d, and the brake element 6j is brought into contact with the stoppers 6g and 6h. The means 4 can be stopped at the standing position and the stowed position. When the display means 4 is at the stowed position, a part of the arc-shaped rib 6d located on the outside is provided on the stopper 6h side where the brake element 6j comes into contact. A notch 6i is formed by notching.

  The notch 6i is formed to fit the brake element 6j in the guide groove 6f of the brake member 6a when the display means 4 is attached to the display means attachment part 1f of the housing 1. On the sliding surface 6e of the arc-shaped rib 6c that is positioned, a protruding locking portion 6k protrudes at a position substantially opposite to the end of the cut-out arc-shaped rib 6d.

  On the other hand, the display means mounting portion 1f of the housing 1 has a bottom so that the braking member 6a of the braking means 6 does not interfere with the bottom wall 1m of the display means mounting portion 1f when the display means 4 is tilted around the pin 1i. A notch hole 1n is formed in the wall 1m, and a support rod 6m for supporting the brake element 6j is provided in a horizontal direction on the side surface of the elastic rib 1p provided substantially perpendicular to the side of the notch hole 1n. Yes.

  The elastic rib 1p is integrally formed with the upper housing 1a and is elastically deformable in the axial direction of the support rod 6m. The support rod 6m protruding from the elastic rib 1p has a tip as shown in FIG. The side is formed in a tapered shape having a diameter gradually increasing, so that the brake element 6j fitted to the support rod 6m is prevented from coming off.

  The brake element 6j is made of a cylindrical body having a diameter slightly larger than the width of the guide groove 6f formed in the brake member 6a, and is entirely formed of elastic rubber or synthetic resin, and is fitted in the guide groove 6f. At this time, the outer peripheral surface is pressed against the sliding surfaces 6e of the arc-shaped ribs 6c and 6d by its own elasticity.

  Next, the operation of the electronic apparatus constructed as described above will be described. The display means 4 mounted on the display means mounting portion 1f of the upper housing 1a is moved from the storage position shown in FIG. 10 to the standing position shown in FIGS. When the electronic device is placed on a desk or the like and used, information such as characters and images displayed on the display panel 4b of the display means 4 may be difficult to see at the storage position.

  In that case, the upper part of the display means 4 protruding from the display means mounting portion 1f is lifted by hand, and the display means 4 is tilted upward about the pin 1i pivotally attached to the display means 4, and displayed on the display panel 4b. The angle of the display means 4 is adjusted so that the information can be easily seen.

  At this time, the brake element 6j fitted in the guide groove 6f of the braking means 6 is pressed against the sliding surface 6e of the arc-shaped ribs 6c and 6d by its own elasticity, and slides on the brake element 6j. Since friction is generated in the display unit 4 due to friction with the moving surface 6e, the tilting operation of the display unit 4 can be performed smoothly, and even if the hand is released from the display unit 4 at an arbitrary adjustment angle, the display unit 4 slides. Since the display means 4 is held at that position by the frictional force with the surface 6e, the angle of the display means 4 can be adjusted steplessly, and the adjustment position does not change excessively.

  On the other hand, when the display means 4 is stored from the upright position to the storage position after use of the electronic device, or when the display means 4 is stored in the storage position so that the electronic device is attached to a wall surface or the like, the upper portion of the display means 4 is moved backward. By pressing, the display means 4 is rotated to the storage position around the pin 1i.

  As a result, the brake element 6j in the guide groove 6f moves relative to the upper side of the guide groove 6f as shown in FIG. 8, and the locking portion 6k protruding from the sliding surface 6e of the arcuate rib 6c on the inner side. Reaches the brake 6j.

  When the display means 4 is further pressed in this state, the brake 6j is strongly pushed downward by the lock 6k when the brake 6j gets over the lock 6k. Since the moving surface 6e is a notched portion 6i that is notched, the elastic rib 1p on which the support rod 6m that supports the brake element 6j protrudes is elastic toward the opposite side of the brake element 6j as shown in FIG. Deform.

  As a result, the locking portion 6k can easily get over the brake 6j, so that the display means 4 can be stored in the storage position with a small operating force, and in the state where the display means 4 is stored in the storage position, FIG. As shown in FIG. 10, the elastic rib 1p returns to the original position, and as shown in FIG. 10, the sliding surface 6e of the inner arc-shaped rib 6c, the stopper 6h, and the locking portion 6k are the outer peripheral surface of the brake element 6j. The movement of the display means 4 is restricted by contact with the display means, so that the display means 4 stored in the storage position does not rattle.

  In the above-described embodiment, an example in which a fixed telephone is used has been described. However, a facsimile having display means may of course be used.

In the electronic device according to the present invention, when the display means is in the storage position, the brake means is locked by the three points of the sliding surface, the stopper, and the locking portion, and the display means does not rattle. As the display means is not damaged, it is not necessary to provide a fixing means such as a fixing claw at a position distant from the pivoting part of the display means by providing a locking portion on the sliding surface, and therefore the display means is enlarged. Even if the display means is an electronic device in which a part of the display means protrudes larger than the housing, the display means stored in the storage position can be securely fixed. It can be applied to all electronic devices having
