There is provided a semiconductor pressure sensor which improves the sensor sensitivity and is excellent in the withstand pressure characteristic and the temperature characteristic. In the semiconductor pressure sensor in which a diaphragm is formed by a cavity provided on one of top and bottom surfaces of a silicon substrate and a plurality of piezoresistors is disposed in the diaphragm edge, a recess which has a larger area than the planar shape of the diaphragm and whose entire edge is located outward from the diaphragm edge in plan view is provided in a protective film which covers the entire surface of the silicon substrate on the diaphragm side. The protective film located on the diaphragm is preferably formed of SiO2.

An inclined surface-equipped lens includes a first inclined surface and a second inclined surface inclined relative to a plane perpendicular to an optical axis, and a corner portion formed by the first inclined surface and the second inclined surface being in contact with each other. Each inclined surface makes a predetermined inclination angle with the plane perpendicular to the optical axis, and the corner portion is located out of the optical axis and raised outward.

An intermediate transfer medium conveying device conveys an intermediate transfer medium by a drive force of one DC motor, in a normal feed direction where the intermediate transfer medium is wound on a winding reel and in a reverse feed direction where the intermediate transfer medium is wound on a feeding reel. The intermediate transfer medium conveying device includes a winding shaft that drives the winding reel during normal feed where the intermediate transfer medium is conveyed in the normal feed direction, a feeding shaft driving the feeding reel during reverse feed where the intermediate transfer medium is conveyed in the reverse feed direction, transmission means for normal feed that transmits a drive force of the DC motor to the winding shaft during the normal feed, and transmission means for reverse feed that transmits a drive force of the DC motor to the feeding shaft during the reverse feed.

After a lead block, which is assembled by fitting a required number of pin terminals into an insulating support member, is connected to an end portion of a flat cable, the lead block is mounted on a lower connector holding portion of a rotary connector. The lower connector holding portion is formed of downward protruding portions of an outer cylindrical portion and a lower cover that are snap-fitted to each other. The downward protruding portion includes a receiving recess, and the downward protruding portion includes a holding wall portion. Tip portions of the pin terminals are inserted into insertion holes of the holding wall portion, so that the lead block is mounted. While stopper portions of the pin terminals are interposed between the holding wall portion and an outer wall of the support member, the support member is disposed so as to be positioned the receiving recess.

A switch apparatus includes first, second, third, and fourth movable contacts held by a slider and sliding on a circuit board in conjunction with the rotational operation of an operation knob, and a belt-like common fixed contact, an auto fixed contact, a down fixed contact, and an up fixed contact provided on the circuit board. The auto fixed contact, down fixed contact, and up fixed contact are distributed on a straight line parallel to the common fixed contact. The third and fourth movable contacts are normally in sliding contact with the common fixed contact.

A connection portion extends from an operation substrate, and a retaining groove of an elastic body is retained in a retaining hole of the connection portion. When a shaft portion of a retaining member is inserted into a through hole of the elastic body and screwed into an internally-threaded hole of a panel, an upper elastic portion of the elastic body is interposed between the connection portion and a support portion of the panel, and a lower elastic portion of the elastic body is interposed between the connection portion and an facing member. When an operation surface of the operation substrate is pressed, the connection portion rotates in a direction and the upper elastic portion and the lower elastic portion of the elastic body are compressed, whereby an appropriate operation reaction force and an elastic return force can be exerted.

A switching substrate on which switching portions are mounted is attached at an angle to a case. The length in the pressing direction of a first push button of a push button unit is larger than the length in the pressing direction of a second push button. A first contact portion about which the push button unit rotates when the first push button is pressed and a second contact portion about which the push button unit rotates when the second push button is pressed are at substantially the same height from the surface of the switching substrate. Therefore, the rotation angle when a first operating surface is pressed can be made equal to the rotation angle when a second operating surface is pressed.

A lens unit includes a lens holder of stainless steel and a converging lens fixed to a lens holding hole of the lens holder. The lens holder is formed by pressing, or stamping from a metal plate, made of a compressed stainless steel plate material, having a predetermined thickness with a narrow tolerance. Upon stamping, the metal plate is fractured, thus forming an outer tapered surface at one end of the outer surface of the lens holder. When the outer surface and the rear end surface of the lens holder are allowed to abut against a positioning recess in order to position the lens holder, the outer tapered surface is opposed to the corner of the positioning recess.

The present invention provides a high-frequency circuit capable of acquiring the original transmission characteristics of a filter by preventing capacitive coupling between input and output terminals of the filter externally attached to the integrated circuit and effectively using a mounting space. The high-frequency circuit includes a rectangular integrated circuit 10 having two long sides 10a and 10b and two short sides 10c and 10d and a SAW filter 15, disposed to be adjacent to the short side 10d of the integrated circuit 10, having input terminals 24a and 24b disposed on the long side 10a side and output terminals 28a and 28b disposed on the other long side 10b side. IC output terminals 22a and 22b connected to input terminals 24a and 24b of the SAW filter 15 are disposed on a position of one long side 10a of the integrated circuit 10 on the SAW filter 15 side, and IC input terminals 26a and 26b connected to output terminals 28a and 28b of the SAW filter 15 are disposed on a position of the other long side 10b of the integrated circuit 10 on the SAW filter 15 side.
