Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device using a pen-type input member for inputting information.

[0002]

2. Description of the Related Art Conventionally, various input tablets such as a resistance film type or an ultrasonic type have been used in various electronic devices. Some of these devices use an input member (hereinafter referred to as a touch pen) for inputting characters and figures by handwriting and clicking for selection. The touch pen includes a material shape that does not damage the input tablet, a mechanism that keeps the pressure of the pen tip constant, or a vibration device that generates vibration. As described above, since the touch pen is a special pen, if it is lost, a normal writing tool such as a mechanical pencil or a ballpoint pen cannot be used as a substitute, and input with an input tablet becomes impossible. Therefore, a method of semi-fixing the touch pen to the electronic device has been considered in order to prevent loss.

As the first conventional example, there is one having a mounting member on the electronic equipment side (for example, Japanese Patent Laid-Open No. 2-20).
2615). FIG. 15 is a perspective view showing this entire structure. FIG. 16 is a sectional view showing a stored state of the touch pen. FIG. 17 is a sectional view showing a detached state of the touch pen. (36) is a touch pen, and (37) is a main body of an electronic device on which the input tablet (38) is placed. Reference numeral (39) is a cover serving as a mounting member, and a pair of pivotal support portions (40) (4) provided at the rear of the main body (37).
0) allows the input tablet (38) to be rotated so as to cover it. Reference numeral (41) is a recess for accommodating the touch pen (36) and extends between the pair of pivotal support portions. The width of the recess is slightly larger than the width of the touch pen (36), and the length of the recess is slightly longer than the length of the touch pen (36). Reference numeral (42) is a claw portion integrally formed with the cover (39), and when the cover (39) covers the input tablet (38), the claw portion (42) is located outside the storage section (41), The touch pen (36) is stored in the storage section (41) (FIG. 16). When the input tablet (38) is exposed, the claw portion (42) projects into the storage portion (41) through the opening (43), whereby the touch pen (36) is pushed out of the storage portion (41). , It becomes easy to take out the touch pen (36) (FIGS. 15 and 1).
7).

As a second conventional example, Japanese Patent Laid-Open No. 2026/1990
The configuration described in Japanese Patent No. 16 will be described. FIG. 18 is a perspective view showing the overall structure, and FIG. 19 is an exploded perspective view showing the structure of the touch pen. Reference numeral (44) is a touch pen having a coil spring (45) serving as a mounting member, and the coil spring (45) is provided inside the touch pen (44) and is movably supported by the touch pen (44). Is always urged toward the outside of the touch pen (44). (47) is an input tablet (38) and a storage section (4
8) is a main body of an electronic device on which is mounted. The storage part (48) is a recess having a width slightly larger than the width of the touch pen (44) and an extension length shorter than the maximum total length of the touch pen (44) and longer than the minimum total length of the touch pen (44), It has a notch (49) having a width smaller than the diameter of the touch pen (44) at one end thereof. At the time of storage, the pen tip is biased inward and the total length is shorter than the total length of the storage part (48) for insertion. In the storage state, the storage section
Both ends of 8) are constantly urged by the coil springs (45) to prevent the touch pen (44) from being accidentally detached. To take out the touch pen (44), the pen tip is urged inward from the cutout portion (49) and the entire length thereof is made shorter than the total length of the storage portion (48) and lifted.

[0005]

In the case of the above-mentioned first conventional example, when the input tablet (38) is not used for input, the touch pen (3
6) is unnecessary, and it is preferable to place it in the storage part (41), but since the claw part (42) projects into the storage part (41), it is completely inside the storage part (41). Can not be placed and stored. Further, in such a state, the touch pen (36) may be dropped and lost due to a slight inclination of the main body (37).

In the case of the above-mentioned second conventional example, the notch (4
Since the width of 9) is smaller than the diameter of the touch pen (44), it is difficult to take it out with a finger. In addition, coil spring (4
Since the biasing force of 5) is used, the structure of the touch pen (44) becomes complicated and the cost increases.
