[0002]

2. Description of the Related Art Conventionally, as a pen storing mechanism of this type,
As shown in FIGS. 6 and 7, a spring 7b is housed in the input pen 7, and when the input pen 7 is housed in the recess 6a provided on the case 6 housing the body of the electronic device by the spring 7b. The tip 7a can be stored in the main body.

When the input pen 7 is housed in the recess 6a of the case 6, the pen tip 7a is pressed against the side wall 6b of the recess 6a in the direction of the arrow H to compress the spring 7b and move the pen tip 7a. It will be stored in the main body of. At this time, the main body of the input pen 7 is swung in the direction of arrow I around the tip of the pen tip 7a, and the input pen 7 is housed in the recess 6a.

In this case, the total length of the input pen 7 is shorter than the total length L of the concave portion 6a because the pen tip 7a is stored in the main body by compressing the spring 7b, and the input pen 7 can be stored sufficiently. Here, the total length 1 of the input pen 7 in the normal state is longer than the total length L of the recess 6a.

After the input pen 7 is housed in the recess 6a, the pen tip 7a jumps out from the tip of the input pen 7 inside the recess 6a by the reaction force of the compressed sprink 7b. Therefore, the input pen 7 is depressed by the reaction force of the spring 7b.

[0006]

In the conventional pen storage mechanism described above, the input pen is stored and held in the concave portion of the case by the spring inserted in the input pen, so that the input cannot be inserted in the pen. When a method, for example, an electromagnetic induction method is used for a tablet, it is necessary to provide a circuit, a power source, and a switch for generating electromagnetic waves inside the pen, and thus the above-mentioned storage and holding method cannot be applied.

Further, since the input pen is held only by the frictional force generated between both ends of the input pen and the recess due to the reaction force of the spring built in the input pen, the input pen can be securely fixed. It is difficult and the input pen may come off from the recess and be lost during movement of the case.

Further, in order to store and hold the input pen, the pen tip must be pressed against the side wall of the recess and then stored, and when the input pen is taken out, the fingertip must be put in and taken out from the gap of the recess, so that the operability is poor.

Therefore, an object of the present invention is to solve the above problems and to eliminate the risk of the input pen being lost irrespective of the internal structure of the input pen and the movement of the main body of the apparatus. To provide a pen storage mechanism.

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of one embodiment of the present invention.
In the figure, a housing 1 accommodates a main body of an electronic device using a pen-type input member as a pointing device. In addition, a cylindrical storage space for storing the pen 2, which is a pen-type input member, is provided inside the housing 1.

A lock 3 is attached to the storage opening of the pen 2 in the storage space of the housing 1 so that the opening diameter of the storage opening can be freely changed. The lock 3 is stored by a spring 4 for biasing the lock. Is urged toward the storage opening so that the opening diameter of the pen is smaller than the maximum diameter of the pen 2. Here, a torsion coil spring is used as the lock biasing spring 4.

A pen discharge spring 5 is stored in the storage space of the housing 1, and the pen 2 is stored in the storage space against the biasing force of the pen discharge spring 5. Become. After the pen 2 is stored, the opening diameter of the storage opening of the storage space becomes smaller than the maximum diameter of the pen 2 by the lock 3 and the spring 4 for biasing the lock, so that the pen 2 pops out of the housing 1. There is no.

Therefore, when the lock 3 is moved so as to increase the opening diameter of the storage port after the pen 2 is stored in the storage space against the biasing force of the spring 5 for discharging the pen, the pen in the storage space is moved. 2 is discharged from the storage space by the reaction force of the spring 5 for discharging the pen. Here, a compression coil spring is used as the spring 5 for discharging the pen.

2 to 5 are views showing a process of storing the pen 2 in the pen storing mechanism according to the embodiment of the present invention. The operation of storing the pen 2 in the pen storing mechanism will be described with reference to FIGS. 1 to 5.

In a state where the pen 2 is not inserted into the storage opening 1a of the storage space of the housing 1, the lock biasing spring 4 receives a torsion moment, and the lock 3 is locked by the lock biasing spring 4. Since the reaction force is applied in the direction of arrow A, the lock 3 is urged toward the storage opening 1a to make the opening diameter of the storage opening 1a smaller than the maximum diameter of the pen 2 (see FIG. 2).

In the above state, when the pen 2 is inserted from the pen tip into the storage opening 1a in the direction of the arrow B, the lock 3
Moves in the direction of arrow C along the tapered portion of the pen 2 against the reaction force of the lock biasing spring 4. At this time, as the lock 3 moves in the direction of arrow C, the storage opening 1

Further, the pen 2 is housed inside the housing 1 by the lock 3 and the spring 4 for biasing the lock and the spring 5 for ejecting the pen, and the pen 2 is secured by the lock 3 and the spring 4 for biasing the lock. Since it does not jump out of the housing 1, the pen 2 does not get lost even when the housing 1 is moving. By using a torsion coil spring as the spring 4 for biasing the lock, the mechanism for fixing the pen 2 in the storage space can be made thin, and the space for the pen storage mechanism can be reduced.

Further, when the pen 2 is stored in the storage space, since the lock 3 is moved by utilizing the tapered portion of the pen 2, the pen 2 is stored by simply inserting the pen 2 from the storage opening 1a and pushing it in. It can be fixed in the space, and the operability when the pen 2 is stored can be improved.

Furthermore, when the pen 2 is taken out from the storage space, simply moving the lock 3 causes the pen 2 to move.
Is discharged from the storage space by the spring 5 for discharging the pen, so that the operability when the pen 2 is taken out can be improved.

Therefore, the pen 2 can be prevented from being lost regardless of the internal structure of the pen 2 and even when the housing 1 for accommodating the main body of the apparatus is being moved. It is possible to provide an excellent pen storage mechanism.
