A timepiece which provides a tactile feel in a simple structure and which can suppress inadvertent rotation of a driving crown is to be provided. A wristwatch includes an elastic material winding stem pipe protruding on the outer side of a case and a distal end portion of which is capable of elastic deformation in a radial direction; a shaft member of a driving crown rotatably inserted into the elastic material winding stem pipe; protrusions formed on the peripheral surface of the driving crown; and trough portions formed in the peripheral surface of the elastic material winding stem pipe and configured to be engaged with the protrusions.

There is provided a crown lock mechanism-installed timepiece which enables a lock mechanism to regulate an operation of a crown by using a simple operation. A crown lock mechanism includes a winding stem, a crown, a lock screw ring, an extrusion spring, and a regulator. The winding stem is connected to a corrector lever of a movement. The crown is fixed to the winding stem. The crown is capable of engaging with the lock screw ring, and the crown is supported by the lock screw ring so as to be movable in an axial direction. The extrusion spring biases the lock screw spring toward the crown. The regulator regulates the lock screw ring to be located at a predetermined position against a biasing force of the extrusion spring, and holds the crown engaging with the lock screw ring so as to stay at a normal hand operation position.

A timepiece in which the width of an edge member mounted to a case band while supporting a transparent member is small is provided. A case accommodating a dial is equipped with an edge portion arranged outside a case band of the case, a cylindrical portion arranged inside the case band, and an edge member having a receiving portion. The edge portion supports a transparent member. The cylindrical portion supports the peripheral portion of the dial from the front side of the case and prescribes the display diameter D of the dial. The receiving portion protrudes from the outer periphery of the cylindrical portion or from the cylindrical portion toward the rear surface side of the case. The edge member is mounted to the case band by a drawing-in mechanism equipped with a drawing-in member and a drawing-in screw.

Timepiece

To provide a wristwatch type wireless telephone improved in terms of handling in that there is no need to change the holding state of the wristwatch type wireless telephone when the wristwatch type wireless telephone is used for telephone conversation by being removed from an arm and held in a hand. In a wristwatch type wireless telephone carried by being worn on an arm by binding with an arm band, a sound radiating hole of a mouthpiece and a sound receiving hole of an ear piece are formed in a surface at a back surface, at the arm side in a state of being worn on an arm.

To provide a wrist mounting type electronic apparatus facilitating attachment and detachment thereof. The wrist mounting type electronic apparatus is constituted by a main body bent substantially in an L-like shape and straps comprising a hard material. An inserting portion is provided at a front end of the strap on one side and is inserted into an inserted portion of the pivotable strap on other side. The inserted portion is penetrated with a bar member which is engaged with a small diameter hole of the inserting portion. Thereby, the wrist mounting type electronic apparatus can be mounted to the wrist. A hinge of the strap is provided with a coil spring and a state of opening the strap relative to a cabinet of the main body is maintained so far as the strap is not engaged.

Hinge assembly and wrist mounting-type electronic apparatus utilizing hinge assembly

A hinge assembly has a tubular member having a longitudinal axis, a peripheral surface, and a slot formed in the peripheral surface. A button member extends into the tubular member to undergo sliding movement in an axial direction along the longitudinal axis of the tubular member and to undergo rotational movement relative to the tubular member. A pin member is connected to the button member and extends into the slot of the tubular member to undergo movement therein during sliding and rotational movement of the button member relative to the tubular member. The button member is biased in a preselected direction of rotation relative to the tubular member by a first biasing member. The button member is biased in an axial direction by a second biasing member.

To provide electronic device, which is easily assembled and disassembled. A cup-shaped introduction tube made of a rubber type member is inserted in an introduction hole provided in a watch case. On an outer peripheral surface of the introduction tube, a convex portion having a uniform semi-arch shape in cross-section in an axial direction is integrally formed. A metal pipe is inserted into the introduction tube, and an outer diameter of the metal pipe and an inner diameter of the introduction tube have a relationship of close fit before insertion. Furthermore, at an end portion of the metal pipe, a brim-shaped edge portion is formed. A ring groove is formed on a cup bottom surface of the introduction tube. In the ring groove, an annular O-ring made of a rubber type member is sandwiched. The O-ring has substantially the same inner diameter as the diameter of a shield line, and the O-ring forms a seal surface among the shield line, the metal pipe, and the ring groove in a crushed state. Furthermore, the shield line is inserted in the watch case while passing through the introduction tube, the rigid pipe, and the O-ring.
