A vehicle switch has a case, a movable body, a spring, a magnet, a detector, and an operating shaft. The movable body is reciprocably accommodated in the case. The spring pushes the movable body in a direction away from an internal bottom of the case. The magnet is attached to the movable body. The detector detects a magnetic flux density generated from the magnet. A lower end of the operating shaft is in contact with the movable body. The movable body has a press contact portion with which the operating shaft is in contact at a point or along a line.

Vehicle switch

A vehicle switch includes a magnet mounted to an operating unit accommodated in an external packaging such that the operating unit can move linearly. A magnetic detector is placed so as to receive different strength of the magnetism from the magnet in the two cases that the operating unit is at the upper limit position and at the lower limit position. A control circuit coupled to the magnetic detector opens and closes a switching device in response to strength of the detected magnetism.

Provided is a switch for vehicles, which includes an intermittent driving device connected to a control device which opens and closes a switching device based on the magnitude of the magnetism of a magnet mounted on an operating body. Therefore, the supply of power from a battery to a detection device and the control device is intermittently performed at a predetermined period by the intermittent driving device.

Switch for vehicles

Provided is a switch for vehicles, including a first switching device which performs the electrical connection/disconnection between a battery and a stop lamp and a second switching device connected to a control device which opens and closes the first switching device based on the magnitude of the magnetism of a magnet mounted on an operating body. Various controls such as auto-cruise control and so on as well as the turn on/off of the stop lamp can be simultaneously performed by the one magnet mounted on the operating body of the switch for vehicles.

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.

Rotation angle sensor device for detecting rotation angle of a rotary shaft

A rotation angle detector is simple in structure and is capable of angle detection with a high resolution. First and second detecting units detect rotations of first and second detecting members rotating in association with a rotating member as detection signals in which predetermined waveforms continue. A control unit connected with the first and second detecting units detects a difference between the waveforms output from first and second detecting units as a gradually increasing detection signal and detects a rotation angle of the rotating member from two signals: the gradually increasing detection signal and the waveform output from the first detecting unit.

Rotation angle detector

A printing apparatus has a small size that facilitates replacement of rolled paper, removal of jammed paper, etc., and alleviates the likelihood of a paper jam with a considerably simple structure. The printing apparatus comprises a rolled-paper holder (,), which is provided with a first holder (,) for use in carrying out printing on rolled paper (,), and a second holder (,) for use in setting the rolled paper (,). The rolled paper (,) is moved from the second holder (,) to the first holder (,) as a main body of the apparatus is shifted from a paper setting position to a printing work position, thereby facilitating the setting of the rolled paper (,) and removal of jammed paper, since the rolled paper (,) can be temporarily supported by the second holder (,) in order to provide sufficient work space when replacing the rolled paper (,) or removing jammed paper.
