Abstract

PURPOSE:To save a useless space, and to set this mechanism at the arbitrary position of a device by providing a pen holder whose one edge is supported to be freely rotable, and a means which ejects the pen by rotating the pen holder upward, in a housing. CONSTITUTION:A semi-cylindrical pen holder 12 is equipped with a shaft 12a and a lever 12b at one edge, and supported by the shaft 12a so as to be freely rotable in housing 10. A T-shaped ejecting nob 13 is equipped with a pin 13a at its lower edge, part 13b which stops the ejection of a pen 11, at one edge of the upper part, and safety lug 13c having the top end of a spring-shaped at its other edge, and supported so as to be slidable on the housing. Then, by making the ejecting nob 13 slide, the lever 12b of the pen holder 12 is pulled through an ejecting link 14, and the pen holder 12 is rotated, so that the pen 11 can be ejected. Thus, the pen housing and ejecting mechanism are united, so that the useless space generated at the time of setting it at an information processor can be saved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pen storage / eject mechanism. More specifically, the present invention relates to a mechanism for accommodating and ejecting a stylus pen accommodated in a device used in a pen input type information processing device such as a system electronic notebook or a clipboard type personal computer.

Conventionally, a touch panel has been used as a man-machine interface to an information processing apparatus. In a device using the touch panel, a stylus pen is used as a means for inputting characters and inputting handwritten figures. In this case, from the viewpoint of portability of the device, the stylus pen must be able to be stored in the device, and when the stylus pen is used, it can be easily taken out from the device, and when not in use, be sure not to pop out. In addition, it is necessary to prepare a mechanism on the information processing device side that can be easily accommodated in the device.

2. Description of the Related Art FIGS. 4 and 5 are views showing a conventional pen storage / ejection mechanism. FIG. 4 (a) is a perspective view of an information processing apparatus, and FIG. 4 (b) is a Z direction in FIG. 4 (a). FIG. 5 is a sectional view taken along line XX of FIG. 4 (b). As shown in FIG. 4A, the pen storing / ejecting mechanism 1 is provided in the peripheral area of the device other than the display unit 3 and the operating unit 4 of the information processing device 2. As shown in FIG. 5 can be stored.

The operation of the pen storing / ejecting mechanism will be described with reference to FIG. First, when a stylus pen (hereinafter referred to as pen) 5 is pressed in the direction of arrow A from the state shown in FIG. 1A, the pen 5 is rotatably supported by a shaft 6 and a spring 7
The projection 8a of the eject knob 8 which is urged in the direction of arrow B is pressed to rotate the eject knob 8 counterclockwise. (B) When the pen 5 reaches the bottom as shown in the figure,
The projection 8a is detached from the pen 5 and returns to its original state, the pen 5 is completely accommodated as shown in the figure, and the projection 8a stops the pen 5 from coming off and holds it.

When ejecting the pen 5, the lever 8b of the eject knob 8 is pushed down to rotate the eject knob 8 in the clockwise direction as shown in FIG. 7C, and the pen receiving portion 8c curved in a J shape. Push the pen 5 upward with. Then, when the eject knob 8 is returned to its original state while the pen 5 is in the upper position, the pen 5 will move to the projection 8a of the eject knob and the edge 9 of the housing cover 9 as shown in FIG.
It is supported by a and is kept in a completely ejected state.

[0006]

[Problems to be Solved by the Invention]
In the eject mechanism, because of the position of the eject knob 8, the eject knob must always be arranged in the peripheral portion of the device.
It limits the flexibility of layout design of each unit and parts when designing the device. Further, since the movement direction of the eject knob 8 is a direction perpendicular to the central axis of the pen 5, the space between the pen 5 and the inner surface of the device cannot be effectively used,
It is also a factor that hinders ultra-high-density mounting.

The present invention is intended to realize a pen storage / eject mechanism which can be installed at an arbitrary position of the apparatus while saving a wasteful space.
