ABSTRACT:
Disclosed are an image control device and a data input device, which comprises an apparatus housing section for removably housing a portable coordinate input apparatus having a control face and a light emitting element, a key control section having many keys, and a light receiving element; in the apparatus housing section are disposed a movable mounting base which is movable between an upper limit position and a lower limit position, so that when the portable coordinate input apparatus is inserted and housed in the apparatus housing section, the movable mounting base is engaged and held in the lower limit position, where the entire upper surface of the portable coordinate input apparatus is nearly flush with the control face of the key control section; and on the other hand, when the portable coordinate input apparatus is removed from the apparatus housing section, the movable mounting base moves up to the upper limit position and a part of the lower surface of the portable coordinate input apparatus becomes nearly flush with the control face of the key control section.
