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 include, for example, Japanese Utility Model Publication No. 27-1708 and Japanese Utility Model Publication No. 4.
Various types have been developed depending on the intended use, as shown in Japanese Utility Model Publication No. 3-29934 and Japanese Utility Model Application Publication No. 12631/1983.

Among these, for example, a cable holding device related to a tabletop memo stand described in Japanese Utility Model Publication No. 27-1708 fixes a support rod bent in a single character shape to the upper end of a support column made of a coil spring, and also fixes the support rod bent in a single character shape to the upper end of the support rod made of a coil spring. 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 to be large in order to prevent this inconvenience, This causes an inconvenience in that the original function of the writing instrument or the like is hindered.

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 make the pen 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 such conventional technology, in order to make it easier to use, the cable has to have a large play area, which makes it impossible to prevent damage when a pen or telephone receiver falls. There is an inconvenience.

On the other hand, with a peso touch type information input machine, a large amount of information is spread over a wide area on the information input machine's panel.
They are arranged in a J-box shape, and the characters or numbers required are selectively selected from among them, and the signal detection pen is used to touch them one after another accurately and quickly, and the relevant position information is sent via the input cable. Since the signal is input to a processing device, it is necessary to easily move the signal detection pen over a wide range, and at the same time, it is easy to operate because a large amount of information is input continuously over a long period of time. is required to be.

On the other hand, in recent years, when an operator inspects a document or replaces a character sheet placed on an input panel, the signal detection pen mentioned above falls from the information input machine body and lands on the floor or on the floor. Accidents in which parts collide with other parts and are damaged are occurring one after another.

For this reason, on the one hand, efforts are being made to make signal detection pens more robust, and on the other hand, improvements regarding their protection devices are currently underway at the same time.

In view of the above, the purpose of this invention is to improve the operability of an information input device by reducing the play in the signal input cable, 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 with a signal input goofle attached to one end thereof, and the other end of the horizontal rod is rotatable so that the one end of the horizontal rod can be vertically rotated. This support is rotatably planted near 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. In order to achieve the above object, a stopper is provided at the connecting portion between the column and the horizontal rod to prevent the one end of the horizontal rod from falling downward.

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

In 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 1A 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 cage support device 10 includes a pillar 11 that is formed to be rotatable, and a supporter 11 that extends from the upper end of the pillar 11 to the tablet 1 .
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 is provided with cable locking portions 1 having a spiral structure at multiple locations such as its tip and center.
2A is formed.

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

Further, the spring mechanism 13 is constituted by a tension spring, and one end of the spring mechanism 13 is connected 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 is locked to the pillar by the spring attachment piece 13B, and the other end is slightly extended to the right of the horizontal rod 12 in FIG. 1. It is locked to.

As shown in FIG. 2, a long groove 12C is formed in the extended portion 12B of the horizontal rod 12 along the horizontal rod 12B, and a plurality of projections and depressions are provided on the inner lower side of the long groove 12C. The tensile force of the spring mechanism 13 can be arbitrarily set to a predetermined magnitude or can 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 approximately horizontal on the left side in FIG. The structure has a downward KM slope.

Horizontal surface 3 facing the valley bottom of this U-shaped connecting member 30
0C and the inclined surface 30D both have a function of determining the rotation angle range of the horizontal rod 12, that is, a function as 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.

Therefore, even if the signal input cable 4 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. This has the advantage that it can be held securely before it collides with the floor or the like.

The pillar support mechanism 14 is as shown in FIG.

A mounting member 20 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 the mounting member 20 is rotatably placed on the upper end surface of the mounting member 20. a column support plate 21 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 110; and a case member 22 that is housed in the case member 22. The home position return spring 23 has a relatively weak reaction force.

The case member 22 is as shown in FIG.

It is formed into a box-shaped cross section with an open bottom, and a threaded portion 22A is formed inside the open end, and this threaded portion 22A is screwed into a threaded portion formed on the outer periphery of the mounting member 20. It is designed to be integrated into 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.

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

The lower end of this spring 23 in FIG. 3 is locked to the support column 11, while the upper end of the spring 23 shown in FIG. It is designed to be locked in one place.

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.

As shown in the figure, an initial load adjustment mechanism 40 for adjusting the initial load applied to the tension spring is provided, and this initial load adjustment mechanism 40 is called a spring mechanism 41.

It is composed of an adapter 42 that holds this screw mechanism 41, a spring hook 41B fixed to the upper end of the movable screw rod 41A of the screw mechanism 41, and an adjustment screw 40C that adjusts the vertical movement of the movable screw rod 41A. It is something.

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, there is a horizontal rod to which a signal input cable is attached at one end, and a horizontal rod that is arranged such that the one end of the horizontal rod can vertically move up and down. A support that rotatably supports the other end is provided, and this support is rotatably planted near the information input panel, so that the signal can be input by the rotational movement of the support and the up-and-down movement of the horizontal rod. Even if the signal detection pen installed at the end of the signal input 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 not hindered by the play in the signal input cable pulled out onto the information input panel as in the past. This inconvenience has been significantly improved, resulting in improved operability.
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, and
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 that they are 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 the play of the signal input cable on the information input panel is almost eliminated.
In addition, the protruding portion of the support column in the right direction as viewed in Fig. 1 is set to be small, making it easier to handle as a whole and reducing its weight, thereby significantly improving operability. A cable holding device for an input device can be provided.

In addition, 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 any structure equipped with a signal input cable. For example, it can be applied as is to information input devices of other types.
