Description

[Detailed description of the invention] The present invention relates to a cable holding device for an information input device, and in particular, a cable holding device for an information input device for holding a signal input cable connected to a signal detection pen for a pen touch type information input device. Relating to a holding device.

Conventionally, so-called cable holders as cable holding devices have been proposed, for example, in Japanese Utility Model Publication No. 27-1708 and Japanese Utility Model Publication No. 4.
As seen in Japanese Utility Model Publication No. 3-29934 and Japanese Utility Model Application Publication No. 50-12631, various products have been developed depending on the progress.

Among these, for example, a cable holding device related to a tabletop memo stand described in Japanese Utility Model Publication No. 27-1708 fixes an L-shaped bent support rod to the upper end of a column made of a coil spring, and The structure is such that the writing instrument is suspended via a string or the like.

For this reason, it is suitable for writing instruments, etc., where the hanging object is relatively light and has a narrow movement range, but for objects that have a wide movement range and are relatively heavy, even if the L-shaped support rod is enlarged, the support Since the entire structure is made of springs, there is an inconvenience that the hanging object cannot be suspended and locked at all times.On the other hand, if the spring effect of the support is set large to prevent this inconvenience, writing instruments This causes the inconvenience that the essential functions of

Furthermore, the structure described in Japanese Utility Model Publication No. 43-29934 merely holds a part of the handset cable, and therefore is essentially a structure that is not intended to hang the handset at all. It has become.

Furthermore, the one described in Utility Model Application Publication No. 50-12631 is
Since the arm body is fixed, the range of movement of the pen may be restricted.

on the other hand. In order to set the pen to be movable over a wide range, there arises the inconvenience that the cable must be provided longer than necessary.
Similar to the one described in Japanese Patent No. 934, it is limited to simply supporting the cable.

For this reason, in order to make the conventional technology easier to use, the cable must have a large play area, which makes it impossible to prevent pens, telephone receivers, etc. from falling on the sides when dropped. There is this inconvenience.

On the other hand, with pen-touch information input devices, a large amount of information is arranged in a matrix over a wide area on the screen of the information input device, and buttons are pressed to select the required characters, numbers, etc. Since the configuration is such that the position information is selectively selected, the signal detection pen is used to select one after another accurately and quickly, and the relevant position information is input to the information processing device via the input cable, the signal detection pen is first selected. It has become necessary to easily move the device over a wide range, and at the same time, it is required to have good operability because a large amount of information must be input continuously over a long period of time.

On the other hand, in recent years, when an operator inspects a manuscript or replaces a character sheet installed on an input panel, the signal detection pen mentioned above falls from the information input machine body and lands on the floor or other surface. A series of accidents have occurred in which parts of the vehicle collide and are damaged.

For this reason, on the one hand, efforts are being made to make the signal detection pen more robust, and on the other hand, the current situation is that improvements are being made simultaneously to the protection device.

In view of the above, the purpose of the present invention is to improve the operability of an information input device by reducing the play in the signal hole capeple, and to prevent the signal detection pen from accidentally falling from the main body of the information input device, such as from the floor. An object of the present invention is to provide a cable holding device for an information input device that can lock the cable before it collides with the information input device.

The present invention includes a horizontal rod to which a signal input cable is attached at one end, and the other end of the horizontal rod is rotatable so that the one end of the horizontal rod can be rotated up and down in the vertical direction. This support is rotatably planted in the vicinity of the information input panel, and a spring mechanism that biases the upward rotational force of the horizontal rod is installed between the support and the horizontal rod. A stopper is interposed between the column and the horizontal rod to prevent the one end of the horizontal beam from falling downward, and the column support mechanism is provided with a stopper that prevents the column support mechanism from rotating. The purpose of the present invention is to achieve the above object by equipping the device with a return mechanism for returning it to its original position.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

Referring to FIG. 1, numeral 1 indicates a tablet as an input panel of a capacitively coupled information input device, and numeral 2 indicates a tablet support plate.

The tablet 1 has a plurality of signal scanning lines (not shown) orthogonal to each other via an insulating film, and a plurality of key areas IA, IA, formed on each intersection area of each scanning line.
It is equipped with...

Scanning signals are sequentially applied to each scanning line at a predetermined timing, and each of these signals is detected by touching a predetermined key area with a capacitively coupled signal detection pen 3,
Thereby, the positional information of the key area 1A is inputted to the information processing device (not shown) via the signal input cable 4.

As shown in FIG. 1, the tablet support plate 2 is equipped with a cable support device 10 having a substantially inverted shape.

This cable support device 10 includes a pillar 11 that is formed to be rotatable, and a support that connects the tablet 1 from the upper end of the pillar 11.
a horizontal rod 12 protruding in the direction; a spring mechanism 13 installed between the horizontal rod 12 and the support 11;
A column support mechanism 14 that rotatably supports the column 11 is provided.

As shown in FIG. 1, the horizontal rod 12 has cable locking portions 1 having a spiral structure at multiple locations such as the tip button and the center portion.
2A is formed.

The entire horizontal rod 12 is pivotally supported at the tip of the column 11 so as to be movable up and down in the direction of the arrow A shown in FIG. 1, starting from the substantially horizontal position shown in FIG.

Further, the spring mechanism 13 is constituted by a tension spring, and one end thereof is attached to the support column 1 as shown in FIG.
1 and the spring mounting member 1 fixed to the spring mounting member 1.
3A, and the other end thereof is engaged with an extending portion 12B that extends slightly to the right in FIG. 1 of the horizontal rod 12. It has been stopped.

As shown in FIG. 2, a long groove 12C is formed along the horizontal rod 12B in the extended portion 12B of the horizontal rod 12, and a plurality of projections and depressions are provided on the inner lower side of the long groove 12C. This allows the tensile force of the spring mechanism 13 to be arbitrarily set to a predetermined value or to be changed stepwise as necessary.

The horizontal rod 12 and the support 11 specifically refer to the support 11.
are connected to each other via a connecting member 30 fixed to the upper end of the two.

That is, the connecting member 30 is formed into a substantially U-shape as shown in FIG.

A protrusion 30A that protrudes upward forming this U-shape,
30B, the horizontal rod 12 is pivotally supported so as to be rotatable up and down as described above.

The bottom of the valley between the protrusions 30A and 30B of the U-shaped connecting member 30 is such that the left side extending from the axis of the support 11 as a boundary in FIG. 2 is approximately horizontal, and the right side in the figure The structure is inclined diagonally downward to the right.

A horizontal surface 3 buttoned at the bottom of the valley of this U-shaped connecting member 30
Both the 0Ci and the inclined surface 30D have the function of determining the rotation angle range of the horizontal rod 12, that is, the function of a stopper.

Therefore, regardless of the strength of the spring mechanism 13, the horizontal rod 12 can only move within the range shown by the chain line and solid line in FIG.
Its rotation is allowed.

For this reason. Even if the signal input cable 4 button and the signal detection pen 3 attached to the cable 4 accidentally fall from the information input device main body, the horizontal rod 12 will not rotate downward, so This has the advantage of being able to reliably hold the object before it collides with the object.

As shown in FIG. 3, the pillar support mechanism 14 includes a mounting member 20 that has a disk-shaped mounting portion 20A projected onto the tablet support plate 2 and is fixed to the tablet support plate 2 with screws or the like, and A column support plate 21 rotatably mounted on the upper end surface of the member 20 and integrated with the lower end surface of the column.

A case member 22 that restrains the vertical movement of the column support plate 21 and allows rotation of the column 11, and a return spring 23 with a relatively weak reaction force housed in the case member 22. It is configured.

As shown in FIG. 3, the case member 22 has a box-shaped cross section with an open bottom, and a threaded portion 22A is formed inside the open end. It is screwed into a threaded portion formed on the outer periphery, thereby integrating the mounting member 20.

Furthermore, a through hole 22B is provided at the center of the upper end of the case member 22, through which the support column 11 is inserted gently, thereby maintaining the installed state of the support column 11.

In this embodiment, a coil spring is used as the home position return spring 23 housed inside the case member 22.

The lower end of this spring 23, which is buttoned in FIG. It is adapted to be locked in any one of the holes 22C.

The plurality of slots 22C and 222C are each formed on the same circumference, and when an excessive rotational force is applied to the support column 11 from the outside, the locking portion of the upper end of the spring 23 is moved to the adjacent slot. It is now possible to escape to 22C.

This prevents the spring 23 from being damaged by external force, and allows it to gently return to its original position in response to normal external force.

FIG. 4 shows an example in which the spring mechanism 13 is constructed of a leaf spring 43.

Even in this case, substantially the same effects as in the case of the above-mentioned tension spring are provided.

Further, in FIG. 5, the spring mechanism 13 described above is constructed of a tension spring as in the case of FIG. 2.

between the lower end of this tension spring and the support column 11.

As shown in the figure, an initial load adjustment mechanism 40 for adjusting the initial load applied to the tension spring is interposed, and this initial load adjustment mechanism 40 is connected to a screw mechanism 41 and an adabyo 42 that holds the screw mechanism 41. and a spring hook 41B fixed to the upper end of the movable screw rod 41A of the screw mechanism 41,
Adjustment screw 40 for adjusting the vertical movement of the movable threaded rod 41A
It is composed of C.

This has the advantage that the initial load of the spring mechanism 13 can be set to an arbitrary value.

As described above, according to the present invention, the horizontal rod has a signal input cable attached to one end thereof, and the other end of the horizontal rod is arranged so that the one end of the horizontal rod can be vertically rotated. Since a pillar that rotatably supports the end portion is provided and this pillar is rotatably planted near the information input panel, the rotational movement of the pillar and the up-and-down movement of the horizontal rod can cause the signal input Even if the signal detection pen installed at the end of the cable moves over a wide range on the information input panel, the signal detection pen can be sufficiently and easily moved to follow the signal input cable, Since the entire area of the information input panel can be covered by providing a slight amount of play in the signal input cable, the information input operation is obstructed by the play in the signal input cable that is pulled out onto the information input panel as in the past. The inconvenience is significantly improved, and the operability is improved.
At the same time, a spring mechanism for rotating one end of the horizontal rod upward is interposed between the column and the horizontal rod,
A stopper is provided at the connection between the support and the horizontal rod to prevent the one end of the horizontal rod from falling downward, so even if the signal detection pen is accidentally dropped from the information input device main body, Since the horizontal rod is locked to the stopper, the signal detection pen button and the signal input cable have the advantage of being completely locked without colliding with the floor, etc., regardless of their weight. When using this, the horizontal rod itself is always subject to upward rotational force, so there is almost no play in the signal input cable on the information input panel.
In addition, the protruding portion of the column to the right as shown in FIG. Equipped with a mechanism that allows the signal input cable and signal detection pen to always return to their original positions slightly, which is unprecedented in that the operator can speed up information input operations. It would be possible to provide an excellent cable holding device for an information input device.

Although the above embodiment specifically illustrates the case where the present invention is applied to a capacitively coupled information input device, the present invention is not necessarily limited to this, and may be applied to a structure equipped with a signal man lever/pull. If so, it can be applied as is to information input devices of other types.
