Data input pen-based information processing apparatus

An information apparatus comprising:

• a first casing having information inputting means, display means and electrically connecting means;
• and
• a second casing having electrically connecting means,
• wherein both of said first casing and said second casing have attaching means, whereby said first casing and said second casing are attachable to each other, and
• wherein at least one of said first casing and said second casing has cover means for covering the electrically connecting means of the at least one of said first casing and said second casing, said cover means being movable so as to permit interconnection of the electrically connecting means of the first and second casings in association with an operation of attaching said first casing and said second casing.

An information apparatus comprising:

• an input pen for inputting information;
• a casing having an input panel to which information is input via said input pen;
• a pen holder, attached to said casing, for holding said input pen;
• a cord for connecting said input pen with said casing;
• and
• N(N.gtoreq.1) hook units for hooking said cord, said N hook units being provided to hook said cord adjacent to a perimeter of said casing.

An information apparatus comprising:

• a first casing having information inputting means, display means and electrically connecting means;
• and
• a second casing having electrically connecting means,
• wherein both of said first casing and said second casing have attaching means whereby said first casing and said second casing are attachable to each other, and
• wherein said electrically connecting means of said first casing and said electrically connecting means of said second casing are interconnectable at different positions in association with an operation of attaching said first casing and said second casing.

An information apparatus comprising:

• a first casing having information inputting means, display means and electrically connecting means;
• and
• a second casing having electrically connecting means,
• wherein both of said first casing and said second casing have attaching means, whereby said first casing and said second casing are attachable to each other,
• wherein said information apparatus further comprises detaching means for detaching said first casing and said second casing from each other, and
• wherein said attaching means provides two manners of attaching said first casing and said second casing in terms of relative directions, wherein said first casing has a substantially rectangular surface, and wherein a first portion of said attaching means is used for one of the two manners of attaching and a second portion of said attaching means is used for another of the two manners of attaching, the first portion and the second portion being arranged in positions so that the first portion substantially coincides with the second portion when the first portion is rotated substantially 90.degree. about an intersecting point of two straight lines, each extending at 45.degree., respectively, from two vertices of a shorter side of the substantially rectangular surface of said first casing.
