Abstract: A control device comprising a control unit configured to control regular operation based on operation on a first switch detecting operation in two opposing directions and operation on a second switch detecting touch on an object, wherein the control unit performs control such that the regular operation based on operation on the second switch is not performed until a regular time set between first and second times passes after operation on the first switch is detected, wherein the first time is a time in which a cumulative occurrence rate at which unintended touch on the second switch by a user after operation on the first switch occurs becomes 100% in an experiment carried out in advance, and wherein the second time is a time in which an intended touch on the second switch by the user after operation on the first switch is first detected.

Abstract: An operation device includes an operating portion including plural adjacent operating regions, plural detection portions that are arranged on the operating portion so as to correspond to the plurality of operating regions to detect contact and each output a detection value, and a determination unit that calculates a calculated value from a sum of the obtained detection values and the largest detection value among the obtained detection values, compares the calculated value to a predetermined threshold value, and thereby decides whether or not to display an image on an electrically connected display device, the image being associated with the detection portion that output the largest detection value.

Abstract: An operation device includes a switch row in which operation switches are disposed, an electrostatic detection sensor disposed on an upper side or a lower side of the switch row and configured to detect two-dimensional coordinate values of an object to be detected coming close to the switch row, and a controller including a determination unit configured to determine which of the operation switches of the switch row is close to the object to be detected, based on a detection result of the electrostatic detection sensor.

Abstract: An operation detection device includes a detector configured to detect a detection target that approaches and contacts an operation surface, and a determination unit configured to, in a case where a plurality of detection values of greater than or equal to a proximity threshold value are located at separate positions of the operation surface due to detection of a non-detection target different from the detection target, set setting ranges having a same predetermined size such that the detection values of greater than or equal to the proximity threshold value are centered. The determination unit is configured to regard a detection value of greater than or equal to the proximity threshold value in a setting range having a smallest one of calculation values calculated from the detection values included in the setting ranges as a detection value with which the detection target is detected so as to determine an operation.

Abstract: An operation device includes a first detection-electrode group disposed around an instrument to which the operation device is attached and including multiple detection electrodes disposed in a first direction, a second detection-electrode group including multiple detection electrodes disposed in a second direction intersecting the first direction, and an insulation layer disposed between the first detection-electrode group and the second detection-electrode group so as to insulate and integrate the first detection-electrode group and the second detection-electrode group. A sensor panel includes the first detection-electrode group, the second detection-electrode group, and the insulation layer. The sensor panel has a shape able to be disposed around the instrument.

Abstract: In the field of dental care, diagnoses have been and being made by means of X-ray images, visual observation, explorer, palpation, fluorometery, insertion of a pocket probe and observation, observation by means of a root canal meter and the use of a Doppler flood flowmeter. However, such diagnoses are invasive and not very clear and three-dimensional X-ray CT apparatus that are being used for diagnoses are very large and complex. Additionally, OCT apparatus for obtaining optical tomographys by using reflection light that are being used by ophthalmologists give rise to problems because of the profile of the detection probe and operability when such an apparatus is used in an oral cavity that contains hard tissues such as teeth and soft tissues such as gingiva for dental care. The present invention dissolves the above identified problems and provides a non-invasive and high resolution dental optical diagnostic apparatus.
