FIGS. 11A and 11B are cross-sectional diagrams showing the microswitch provided in the coordinate input device of the second embodiment of the present invention. FIG. 11A is a diagram showing a state where the inscribable sheet material 34 does not exist between the flap part 16 and the operation part 8 a. FIG. 11B is a diagram showing a state where the inscribable sheet material 34 exists between the flap part 16 and the operation part 8 a.
As shown in FIG. 11A, when the flap part 16 is closed when the inscribable sheet material 34 does not exist between the flap part 16 and the operation part 8 a, the contact of the microswitch 36 is not pressed because the contact is placed within the recessed part 37. Therefore, the microswitch 36 is in an OFF state.
FIGS. 14A and 14B are cross-sectional diagrams showing the photocoupler provided in the coordinate input device of the variant of the second embodiment of the present invention. FIG. 14A is a diagram showing a state where the inscribable sheet material 34 does not exist between the flap part 16 and the operation part 8 a. FIG. 14B is a diagram showing a state where the inscribable sheet material 34 exists between the flap part 16 and the operation part 8 a.
The photocoupler 39 includes a light-emitting element 39 a and a light-receiving element 39 b. The light-emitting element 39 a emits light. The light-receiving element 39 b receives light emitted from the light-emitting element 39 a. The light-receiving element 39 b is switched on and off according to the reception of the light. The through-hole 40 in the flap part 16 is positioned so as to oppose the photocoupler 39.
The photocoupler 39 is connected to the control part 38 and switches the detection mode between the relative value mode and the absolute value mode according to the ON/OFF state of the light-receiving element 39 b.
For example, if the light-receiving element 39 b is in the OFF state, that is to say, the inscribable sheet material 34 does not exist on the operation surface 8 a, the detection mode is switched to the relative value mode. In the relative value mode, the points on the coordinate are indicated as relative positions, and the coordinate input device 1 is used as a normal pointing device such as a mouse.
As shown in FIG. 25, the sheet unit 53 includes the PET films 25, 26 and the operation surface 8 b. When a symbol “1” on the operation surface 8 b is pressed down in a direction of an arrow, regions of the PET films 25, 26 corresponding to the symbol “1” will be in contact and the voltage division ratio is altered. The contact position is then detectable by measuring this voltage division ratio.
Program code instructions are stored on the CD-ROM 95 which are read by the CD-ROM drive 72. The instructions are process in the computer main body 98. The CD-ROM 95 corresponds to the “processor readable medium” in claims. The term “processor readable medium” includes any instruction storage device, such as, magnetic disks (floppy disks), optical disks including DVDs, magneto optical disks such as MOs, semiconductor memory cards such as PC cards and other types of computer-readable devices and media.
1. A coordinate input device outputting information to an external device, the coordinate input device comprising:
a coordinate detecting part detecting a position of a touch on an operation surface, as coordinate information, so as to generate a signal corresponding to the coordinate information of said position to be used by the external device; and
a holding part having an opening and being capable of holding an inscribable sheet-like material on said operation surface, said sheet-like material being accessible through said opening,

a processing circuit processing said coordination information;
a holding part having an opening and being capable of holding an inscribable sheet-like material on said operation surface, said sheet-like material being accessible through said opening;
a detecting mechanism detecting a presence or a type of said sheet-like material placed on said operation surface; and
a switching information generating part generating switching information used for switching processing functions in response to a result obtained from said detecting mechanism,
wherein by producing said touch on said operation surface, the signal corresponding to said coordinate information is supplied while preserving inscribed marks corresponding to the touch on the operation surface on said inscribable sheet-like material, and
9. The coordinate input device according to claim 8, wherein said detecting mechanism is provided with a plurality of detecting elements and detects the presence of and, if present, the type of said sheet-like material according to a type of combination of detection states of said detecting elements.
