The present disclosure provides an input device that puts signals into equipment in response to turning action and that can come down in thickness along an axis of a rotary shaft. The input device includes a knob configured to be turned, a rotary shaft configured to turn together with the knob, and a flange disposed around an outer peripheral surface of the rotary shaft. The flange is designed to regulate turning of the rotary shaft. The input device further includes an elastic component that is disposed around the outer peripheral surface of the rotary shaft and is fastened to the flange, a rotation controller that permits or inhibits turning of the elastic component, and a detector that detects a rotational state of the rotary shaft.

Input device

A rotation angle detection apparatus includes a main rotatable body, a pair of sub rotatable bodies, and a control circuit. The sub rotatable bodies are rotated in a linked motion with the rotation of the main rotatable body and are overlapped with each other. The control circuit detects a rotation angle from a rotation of one of the sub rotatable bodies, and detects a rotation phase difference between the rotation of one sub rotatable body and the rotation of the other sub rotatable body of the pair of the sub rotatable bodies. From the two detected signals, the control circuit calculates a rotation angle of the main rotatable body.

Rotation angle detection apparatus

The push-type vehicle switch has a case, an actuator, a movable contact, and a cap made of elastic material. The case has an opening and a fixed contact implanted inside thereof. The actuator is contained in the case reciprocably. The movable contact is provided facing the fixed contact and connects to and disconnects from the fixed contact according to reciprocable movement of the actuator. The cap covers the opening of the case.

Push-type vehicle switch

A rotation angle detector is provided with a spring to thrust a rotary body against protrusions formed on an inner wall of an opening via a detector body in a manner to keep the rotary body rotatable without any play in a linked motion with a steering shaft. As a result, the detector can detect rotation angles of the steering shaft with high accuracy.

An antenna includes a first core made of magnetic material, a coil including a conductive wire wound around a predetermined region of the first core, and a second core made of magnetic material. The second core is operable to move an inside of the coil. The antenna has a resonant frequency adjustable over a wide rage.

A roller device includes a motor and a speed reducer inside a cylindrical roller or arranged coaxially, and an electronic apparatus includes a printer using the roller device. This roller device comprises a motor ( ) disposed on a cylindrical roller ( ), a sun gear ( ), planet gears ( ), a first inner tooth gear ( ) provided inside of the cylindrical roller ( ), and a second inner tooth gear ( ) provided inside of a bearing element ( ). The rotation of the bearing element ( ) is suppressed by a predetermined force. Thus the rotation of the motor ( ) is decelerated, and the cylindrical roller is rotated at a reduced speed. By rotating the bearing element with a force greater than a predetermined force, the cylindrical roller can be rotated manually.

Roller device and electronics using the roller device

A drive apparatus for driving an information recording medium encased in a cartridge has a protection element for protecting the recording medium. The drive apparatus has an action member for cooperating with the protection element. The action member is projected out of the apparatus when the cartridge is inserted into the apparatus, and remains in the apparatus when the cartridge is detached from the apparatus. The apparatus comprises a drive unit and a cartridge mounting unit disposed on a base body of the drive unit. The cartridge mounting unit han an operation button disposed at a position which is furthest apart from the attached cartridge and opposite to the base body with respect to the attached cartridge. When the recording medium is a flexible disk, the disk is pressed onto a recording or reproducing head by a pad. An arm for supporting the pad allows the pressure exerted by the pad on the disk to increase with the rotation of the disk.

Apparatus for loading and driving an information recording medium

A compact stepping motor is equipped with at least four stator plates positioned in parallel with each other, a rotor with a rotary axis perpendicular to the stator plates, and at least two energizing coils each positioned between each two of the stator plates. The rotor is positioned out of the energizing coils. The center axes of the coils and the rotary axis of the rotor are in parallel with each other. One coil is positioned between one pair of stator plates and one coil is positioned between the other pair of stator plates and share a common center axis. Circumferentially arranged stator poles extend from each stator plate perpendicularly to the each stator plate so as to surround the rotor at a specified distance.
