DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus such as a portable computer having a pen for inputting information by hand.

[0002]

2. Description of the Related Art In order to realize easy-to-use operability, various types of portable information processing apparatuses used for business or personal information management adopt a pen input method.

This type of information processing apparatus has a flat box-shaped casing. The housing has an upper wall and a peripheral wall connected to a peripheral edge of the upper wall, and a display opening is formed in the upper wall. A liquid crystal display device is housed inside the housing. The liquid crystal display device has a display screen for displaying various information such as a schedule and an address, and a tablet is arranged on the display screen. The tablet has a transparent input screen, and the input screen is exposed to the outside of the housing through the display opening.

[0004] The input screen is provided with various icons for switching functions and display modes and a handwriting input area. Therefore, various editing or input operations can be performed by pressing a desired icon on the input screen with a pen or by inputting information such as characters and figures by hand in the input area.

[0005] By the way, a pen-input type information processing apparatus includes:
A pen storage unit is provided for storing the pen in a removable manner. The pen housing is formed inside the housing and has an insertion opening opened in the peripheral wall of the housing.
A lock mechanism is provided at the end of the pen housing facing the insertion slot. The lock mechanism includes a chuck that removably grips the pen tip of the pen, and an ejection spring that pushes the pen toward the insertion slot.

[0006] When the pen is inserted into the pen receiving portion from the insertion slot, the pen tip of the pen hits the chuck, which grips the pen tip and compresses the ejecting spring. As a result, the pen is locked in the pen housing so as not to be taken out.

To remove the pen from the pen housing, the end of the pen facing the insertion slot is pressed with a fingertip, and the pen is pushed into the pen housing. By this pressing, the chuck is moved in a direction of detaching from the pen tip, the lock of the pen is released, and the pen is forcibly pushed out toward the insertion slot by the restoring force of the compressed spring.

[0008] As a result, the end of the pen opposite to the pen tip protrudes out of the housing, so that the end of the pen can be grasped by hand and the pen can be easily removed from the pen housing. Can be taken out.

[0009]

In the conventional information processing apparatus, when the pen is to be taken out of the pen housing, the pen is forcibly pushed out of the insertion slot by the restoring force of the spring. The pen may jump out of the insertion slot too much. Therefore, there is a problem that the pen falls out of the housing and the pen is lost or damaged due to this.

Further, when the information processing device is stored in a bag or the like and carried, if the pen is pressed undesirably, the pen may come out of the insertion slot by any chance,
In this regard, there is still room for improvement.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an information processing apparatus capable of preventing a pen from jumping out of a pen housing and preventing the pen from being lost or damaged. I do.

[0012]

According to an aspect of the present invention, there is provided an information processing apparatus, comprising: a housing having a pen housing portion and an insertion port connected to the pen housing portion; A pen for inputting information that is removably inserted into the pen housing portion of the housing through the insertion slot; installed at the end of the pen housing portion facing the insertion slot, and is inserted when the pen is inserted into the pen housing portion.

The pen is arranged at a pen shaft having a pen tip and an end of the pen shaft opposite to the pen tip, and is positioned near the insertion opening when the pen is inserted into the pen housing. A clip that can be elastically deformed in a direction that comes into contact with and separates from the outer peripheral surface of the pen shaft, and the pen housing portion enters a gap between the pen shaft and the clip when the pen is inserted, It is characterized in that the pen has a stopper which is detachably hooked to the clip when pushed out toward the insertion opening via a spring.

[0013] In order to achieve the above object, the present invention is directed to claim 7.
The information processing device described in (1) above has a housing having an upper wall on which an input screen for inputting information by hand is arranged, and a peripheral wall connected to a peripheral portion of the upper wall; and presses the input screen of the housing. A pen which is provided inside the housing and has an insertion opening opened in the peripheral wall, and a pen housing portion into which the pen is removably inserted through the insertion opening; The pen is installed at the end of the pen housing facing the insertion slot, locks the pen so that it cannot be removed when the pen is inserted into the pen housing, and inserts the pen by the urging force of the spring when the pen is unlocked. And a lock mechanism having an eject function for pushing out toward the mouth. The pen is arranged at a pen shaft having a pen tip and an end of the pen shaft opposite to the pen tip, and is positioned near the insertion opening when the pen is inserted into the pen housing. A clip that can be elastically deformed in a direction that comes into contact with and separates from the outer peripheral surface of the pen shaft,
In addition, the pen housing portion enters the gap between the pen shaft and the clip when the pen is inserted, and is detachably hooked on the clip when the pen is pushed out toward the insertion port via a spring. It is characterized by having a stopper.

In such a configuration, when the lock of the pen by the lock mechanism is released, the pen is pushed toward the insertion port by the urging force of the spring. On this occasion,
Since the stopper of the pen housing is inserted into the gap between the pen shaft and the clip, when the pen is forcibly pushed out toward the insertion slot as described above, the positional relationship between the stopper and the clip is relatively determined. The stopper is caught by the clip when the pen shaft changes to a certain extent and is pushed out of the insertion slot to some extent.

Therefore, the pushing of the pen by the spring is stopped, and the pen is kept in a state where the end of the pen shaft on the clip side protrudes from the insertion opening. Therefore, even when the pen is to be taken out with the insertion opening obliquely downward, the pen does not jump out of the housing due to excessive momentum, and loss or damage of the pen can be prevented beforehand. .
