Abstract
Abstract A pocket size personal organizer including a CPU for carrying out a data processing operation, an LCD cell for displaying the operation result of the CPU and X- and Y-drivers for driving the LCD cell. The electronic device is separated into a body member and a cover member which are collapsibly connected to each other. The CPU and one of the drivers are arranged in the body member, and the LCD cell and the other driver are arranged in the cover member. An electrical connection between the parts is carried out by heat seal connectors arranged at a hinge bridge portion.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
131 words
A pocketable electronic device, comprising: a main body member; a cover member collapsibly connected to the main body member by a hinge portion; a CPU arranged in the main body member for carrying out a data processing operation; an LCD cell arranged in the cover member for displaying a result of the data processing operation of the CPU; X- and Y- drivers separately arranged in the main body member and the cover member for supplying display drive signals separated in X- and Y-directions to the LCD cell which is arranged in parallel with one of the X- and Y-drivers-drivers in a flat plane in the cover member; and heat seal connector means arranged in a hinge bridge portion which electrically connects the CPU, the LCD cell and the X- and Y-drivers.
Claim 2
Dependent Claim

A pocketable electronic device, comprising: a main body member; a cover member collapsibly connected to the main body member by a hinge portion; a CPU arranged in the main body member for carrying out a data processing operation; an LCD cell arranged in the cover member for displaying a result of the data processing operation of the CPU; X- and Y- drivers separately arranged in the main body member and the cover member for supplying display drive signals separated in X- and Y-directions to the LCD cell which is arranged in parallel with one of the X- and Y-drivers-drivers in a flat plane in the cover member; and heat seal connector means arranged in a hinge bridge portion which electrically connects the CPU, the LCD cell and the X- and Y-drivers.
Claim 3
Dependent Claim
47 words
The electronic device of claim 1, wherein the CPU, the LCD cell and the X- and Y-drivers are arranged so that the CPU and the LCD cell are diagonally opposed in the flat plane and the X- and Y-drivers are also diagonally opposed in the flat plane.
Claim 4
Dependent Claim
72 words
The electronic device of claim 2, wherein, when the cover member is opened away from the main body member in a flat plane, the CPU, the LCD cell and the X- and Y-drivers are arranged in approximately vertexes of a rectangle, and an electrical connection of the adjacent two parts of the CPU, the LCD cell and the X- and Y-drivers is carried out in a two-dimensional manner along approximately direct lines.
Claim 5
Dependent Claim
48 words
The electronic device of claim 1, wherein the CPU and the X-driver for driving segment electrodes of the LCD cell are arranged in the main body member, and the LCD cell and the Y-driver for driving common electrodes of the LCD cell are arranged in the cover member.
Claim 6
Dependent Claim
38 words
The electronic device of claim 1, wherein the heat seal connector means in said cover member side is held to the cover member by a part of an LCD which retains the LCD cell to the cover member.
Claim 7
Dependent Claim
57 words
The electronic device of claim 1, wherein the heat seal connector means in said main body member side is held to the main body member by a heat seal retainer, and the heat seal retainer includes a projection member which extends under a bottom end of a circuit board and which is held by the circuit board.
