Title: Ophthalmic device
Inventor: KATOU KOUKI
IPC: A61B3/10
Filed: 1995-02-28
Abstract: PURPOSE: To provide an efficient measurement while preventing misoperation and reduce burdens to an operator and a subject, by receiving a scattered light of a target forming means which is reflected by eyelids, by detecting the presence of eyelid or not from received light amount, and by stopping initiation of operation when the eyelids are detected. CONSTITUTION: Light bundles ejected from light sources 10 and 20 do not focus into image and are reflected on an eyelid surface when cornea Ec is covered by the eyelid by means of blinking of a test eye. This scattered light is incident into each detecting optic system through the same pathway as the reflected light of the cornea Ec. A measurement stopping signal is outputted to a measurement control system 31 when the output is larger than a standard value by comparing the output signal of a receiving element 16 with the standard value, by means of a stopping signal generating system 33. A trigger signal is stopped to be generated and the operation of a measurement system 32 is stopped regardless of input of alignment completion signal from a position operating system 30, when this stopping signal is received by the measurement control system 31.

Title: Keyboard device
Inventor: SAITO TOSHIMITSU
IPC: G06F3/02
Filed: 1987-03-25
Abstract: PURPOSE:To ensure the application of a keyboard in common to the processing of different types of documents by inhibiting the code corresponding to an operated additional key in case the document soft indication contents show a set state of the document soft for application at one side. CONSTITUTION:When the foreign language soft correspondence set by the operation of a conventional key 2 not a KANA (Japanese syllabary) character key 3 is decided, a process is carried out to produce a key code corresponding to the foreign language soft via a keyboard for overseas use.
