## Abstract

A portable electric apparatus includes an LCD panel for displaying and obtaining information by using a pen member. The apparatus provides for a storage portion of the pen member on the surface of the portable electric apparatus. The storage portion provides for a holding member which holds the pen member in a stable manner. The holding member is made of an elastic material and covers the pen member in the storage portion. The pen member has a flat oval shape in cross-section so as to be stable when stored in the storage portion.

## Claims

### Claim 1

A portable electric apparatus processing input information and displaying results of said information processing, which comprises:
a panel member displaying processing results and information for said portable electric apparatus;
a pen member inputting said information to said panel member;
a storage member located on a surface of said portable electric apparatus, said storage member storing said pen member therein wherein said storage member has a guide rail guiding said pen member; and
a holding member holding said pen member on the surface of the portable electric apparatus.

### Claim 2 (depends on 1)

A portable electric apparatus recited in claim 1 wherein said holding member provide is formed of a material which covers a surface portion of said storage portion.

### Claim 3 (depends on 1)

A portable electric apparatus recited in claim 1 wherein said pen member is oval shaped in cross section.

### Claim 4 (depends on 3)

A portable electric apparatus recited in claim 3 wherein said pen member has a flat surface of a predetermined length in proximity with a rear end of said pen member.

### Claim 5 (depends on 1)

A portable electric apparatus recited in claim 1 wherein said storage member has a recess with which said pen member engages.

### Claim 6 (depends on 1)

A portable electric apparatus recited in claim 1 wherein said rail further has a notch which is engageable with said pen member.

### Claim 7 (depends on 2)

A portable electric apparatus recited in claim 2 wherein said holding member is engageable with an end portion of said storage member.

### Claim 8

A portable electric apparatus processing input information and displaying results of said information processing, which comprises:
a panel member displaying processing results and obtaining information for said portable electric apparatus;
a pen member inputting said information to said panel member, said pen member further comprising a guide portion guiding storage of said pen member;
a storage member provided on a surface of said portable electric apparatus, said storage member storing said pen member in the storage member, corresponding to said guide portion; and
a holding member holding said pen member in said storage member, said holding member being made of an elastic material.
