JPS63116225A - Input pen for electromagnetic tablet - Google Patents

Abstract

PURPOSE:To easily extract and replace spare ink of a ball-point pen by picking the point of the ball-point pen with finger at the time of its replacement by forming a notch part with which the end part of a sliding lever to be operated from the external is locked on an outer case. CONSTITUTION:The sliding lever 10 is fixed on an interlocking rod 6 for holding the spare ink 4 of the ball-point pen and operated from the outside of the case. The end part 10A of the lever 10 is locked on the case 1 and the notch part 14 to be a space required for moving the end part 10A when contacts 7, 8 are closed by the pen pressure of the pen at the time of inputting data is also formed on the case 1. At the time of inputting data, the end part 10A is moved to a prescribed position of the notch part 14 and the contacts are turned on to input the data, and at the time of not data input, the end part 10A is locked on the original position. Since the lever 10 can be slided by operation from the external and projected so that the spare ink can be picked with fingers at the time of replacing the spare ink of the ball-point pen, the spare ink of the ball-point pen can be easily replaced and the handling of the pen can be improved.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an input pen used by replacing the refill of an electromagnetic doublet ballpoint pen in a drawing image input device.
In particular, the present invention relates to the structure of an input pen suitable for replacing refills of ballpoint pens.

[Conventional technology]

FIG. 3 shows the structure of a conventional input pen for an electromagnetic tablet. 1o is a main body case, 11 is an inner case wrapped with a coil 12 that generates a magnetic field on the tablet surface, 13 is a refill for a ballpoint pen, 14 is a coil spring, and 15 is a device that resists the spring force of the coil spring 14 when inputting data. Depending on the pen pressure, contacts 17 and 18 are set to 0N in conjunction with the refill of the ballpoint pen.
- The interlocking rod that turns OFF, and the ballpoint pen refill side of this interlocking rod 15, insert the ballpoint pen refill from the inner cylindrical surface of the ballpoint pen refill to the extent that it can be pulled out by grasping the tip of the ballpoint pen refill with your fingers. A pin 30 with a spring force is fixed on the outside for holding. Reference numeral 19 designates a guide for a connecting rod 15A which is connected to the coil spring 14 and which connects the contact 17 to ensure a gap with the contacts 17 and 18 in addition to the input waiting area. In addition, the coil spring 14 side of this guide is connected to the inner case.
: By doing so, the void is secured. In the input pen configured as described above, the accuracy of human input data decreases as the magnetic field generated by the coil 12 moves away from the tablet input surface. Only had minimal exposure. Incidentally, related input pens of this type include, for example, Japanese Utility Model Application Publication No. 57-194157.

[Problem that the invention seeks to solve]

In the above-mentioned conventional example, no consideration was given to the structure so that the ballpoint pen refill could be easily replaced by grasping it with one's fingers.
I couldn't say that it was easy to use.

An object of the present invention is to provide an input pen that operates in the same manner as the conventional example when inputting data, and that when replacing the refill of a ballpoint pen, the refill of the ballpoint pen can be easily removed and replaced by grasping the tip of the ballpoint pen with a finger. The goal is to provide a structure for

[Means for solving problems]

The above object includes a means for sliding a guide and a connecting rod that move integrally with the refill of the ballpoint pen so that the refill of the ballpoint pen protrudes from the inner case within the inner case when refilling the refill of the ballpoint pen. This is achieved by

[Effect]

In other words, we designed the ballpoint pen refill to slide through the inner case, so the ballpoint pen refill
Be able to grasp it with your fingers. This makes it easy to replace the ballpoint pen's lead when it runs out of ink, improving usability. Also, when inputting data, the end of the lever is locked to the outer case by sliding the guide that secures the gap between the connecting rod and the contact.

As a result, the guide is locked, so that the contact points are turned on and off by the brush stroke applied to the refill of the ballpoint pen.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a main body case, 2 is an inner case wrapped with a coil 3 that generates a magnetic field on the tablet I surface, 4 is a refill for a ballpoint pen, 5 is a coil spring, and 6 is an interlocking rod.
When inputting data against the spring force of the pen, the contacts 7 and 8 are turned ON and OFF in conjunction with the refill of the ballpoint pen by the pressure of the pen. Further, on the ballpoint pen refill side of the interlocking rod 6, there is a cylindrical inner peripheral surface of the ballpoint pen refill for holding the ballpoint pen refill to the extent that it can be pulled out by grasping the tip of the ballpoint pen refill with your fingers. Pin 30 with outward spring force
is fixed. Reference numeral 9 designates a guide for a connecting rod 6A which is connected to the coil spring 5 and which connects the contact 7 to ensure a gap between the contacts 7 and 8 in addition to the input position.

10 is a lever fixed to the interlocking rod 6A and moves the interlocking rod 6 and ballpoint pen refill 4 together; 12' and 13 are elongated holes passing through the case for sliding the levers of the inner case and the outer case; 11 passes through the guide 9 and connects the contacts 7 and 8 to 0N through the pin that fixes the lever and the interlocking rod 6A.
- An elongated hole 14 that secures a gap for turning off is a cut that requires a space for locking the end 10a of the slide lever and allowing one end 10a of the lever to move when the contacts 7 and 8 are closed by the pressure of the pen during data input. It is a missing part. According to this embodiment configured in this way, when inputting data, the end 10a of the lever moves to the position indicated by the dotted line in the notch 14, turns on the contact, and inputs data. When not in use, the end of the lever 10a is locked, as shown in the solid line position.

Furthermore, when refilling a ballpoint pen, the user can slide the lever as shown in FIG. 2 to project the refill of the ballpoint pen to the extent that it can be grasped with one's fingers, which has the effect of easily replacing the refill of the ballpoint pen.

〔Effect of the invention〕

According to the present invention, since the refill for the ballpoint pen can be protruded from the inner case using the lever, the refill for the ballpoint pen can be easily performed, thereby improving usability.
