A torsion spring 29 is disposed between the spring accommodating recess 21 c of the upper case 21 and the spring accommodating recess 12 b of the rotor member 12.

(Mechanical key reversing structure)
The key unit 1 configured as described above has a case 20 that supports the rotor member 12 so that it can be reversed left and right with reference to the fully deployed position of the mechanical key 10, and an urging direction based on the fully deployed position of the mechanical key 10. And a torsion spring 29 to be reversed. The mechanical key 10 is supported so as to be rotatable and retractable in the component storage spaces 20a and 20a opened on the left and right side walls of the case 20 with the release button 27 as the rotation center axis.

  As shown in FIGS. 4 and 5, the torsion spring 29 has a substantially cylindrical coil portion 29 a that generates a torsional reaction force and a pair of spring end portions 29 b and 29 b, and the outer periphery of the release button 27. Is inserted into the surface. Each spring end portion 29b is formed by bending in the same direction from both ends of the coil portion 29a, and is arranged in parallel on the same vertical plane.

  In the illustrated example, each spring end portion 29b is arranged in the radial direction of the coil portion 29a. As shown in FIG. 6A, the locking hole 12c of the rotor member 12 and the locking hole 21d of the upper case 21 are provided. It is fixed to.

  The mechanical key 10 is provided with a torsional force that urges the mechanical key 10 in both the clockwise and counterclockwise directions when viewed from the front of the upper case 21 by a single torsion spring 29. The torsion spring 29 generates a torsional reaction force in a direction in which the pair of spring end portions 29b are expanded, and a torsional reaction force in a direction in which the torsion spring 29 is narrowed.

  Accordingly, when the mechanical key 10 is stored in the left component storage space 20a, the spring force of the torsion spring 29 acts in the clockwise direction when viewed from the front of the upper case 21, and therefore the left storage position. The mechanical key 10 can be automatically rotated to the fully deployed position.

  On the contrary, when the mechanical key 10 is stored in the right component storage space 20a, the spring force of the torsion spring 29 acts in the counterclockwise direction when viewed from the front of the upper case 21. The mechanical key 10 can be automatically rotated from the storage position on the right side to the fully deployed position.

  The torsion spring 29 may have a configuration in which, for example, a pair of spring end portions 29b are arranged on the inner side in the circumferential direction or the outer side in the circumferential direction of the coil portion 29a. By adopting the single torsion spring 29, it is possible to reduce the number of components and simplify the configuration.

(Key unit operation)
When the mechanical key 10 of the key unit 1 configured as described above is rotated from the retracted position to the fully deployed position, the release button 27 is pushed against the spring force of the coil spring 28 to release it. The locked state between the restricting protrusion 27a of the button 27 and the restricting recess 12f of the rotor member 12 is released.

  The restricting projection 27a of the release button 27 is held in a state of being engaged with the engaging recess 22d of the lower case 22 even when the pushing operation of the release button 27 is released. The portion 27 a is biased in the fully deployed direction of the mechanical key 10 by the spring force of the torsion spring 29, and elastically contacts the sliding surface 12 d of the rotor member 12 by the spring force of the coil spring 28.

  Accordingly, the rotor member 12 has the mechanical key while sliding the sliding step portion 21a of the upper case 21 and the sliding step portion 22b of the lower case 22 by the spring force of the torsion spring 29 with the release button 27 as the rotation center. 10 protrudes outward from the storage position and automatically rotates to the fully deployed position.

  When the mechanical key 10 reaches the fully deployed position, the spring force of the torsion spring 29 returns from the biased state to the original natural state, and the restricting protrusion 27 a of the release button 27 is moved by the spring force of the coil spring 28 to the rotor member 12. The position is regulated by fitting into the regulation recess 12e. The posture of the mechanical key 10 is maintained by returning the release button 27 to the original position where the release button 27 can be pushed.

  On the other hand, when storing the mechanical key 10 from the fully deployed position to the retracted position, the release button 27 is pushed in against the spring force of the coil spring 28 and the mechanical key 10 is manually rotated from the fully deployed position to the retracted position. By operating, the locked state between the restricting protrusion 27a of the release button 27 and the restricting recess 12e of the rotor member 12 is released.

  As shown in FIG. 6D, the restricting protrusion 27a of the release button 27 is kept engaged with the engaging recess 22d of the lower case 22 even when the pushing operation of the release button 27 is released. Even if the mechanical key 10 is manually rotated toward the retracted position, the restricting protrusion 27a of the release button 27 is elastically applied to the sliding surface 12d of the rotor member 12 by the spring force of the coil spring 28. Contact.

  Accordingly, by manual operation, the rotor member 12 is slid into the sliding step portion 21a of the upper case 21 and the sliding step portion 22b of the lower case 22 against the spring force of the torsion spring 29 with the release button 27 as the rotation center. The mechanical key 10 is rotated from the fully deployed position to the retracted position while being moved.

  When the mechanical key 10 reaches the retracted position, the restricting protrusion 27a of the release button 27 is fitted into the restricting recess 12f of the rotor member 12 by the spring force of the coil spring 28, and the position of the mechanical key 10 is restricted. Retained.

  According to the key unit 1 configured as described above, when the mechanical key 10 is stored in the left component storage space 20a, the mechanical key 10 is moved to the case 20 by the spring force of the torsion spring 29 in the clockwise direction. It automatically rotates from the left storage position to the fully deployed position.

  On the contrary, when the mechanical key 10 is stored in the right part storage space 20 a, the mechanical key 10 is moved from the storage position on the right side of the case 20 by the counterclockwise spring force of the torsion spring 29. It will automatically rotate to the fully deployed position.

(Effect of embodiment)
According to the key unit 1 configured as described above, the following effects can be obtained in addition to the above effects.

  With a simple configuration, the mechanical key 10 can be configured to be horizontally reversible with reference to the fully deployed position of the mechanical key 10.

  Since the mechanical key 10 is configured to be reversible in both left and right directions, it can be used for both left-handed and right-handed operators.

  Although the configuration in which the single restricting protrusion 27a is arranged in the circumferential direction of the release button 27 is illustrated, for example, restricting recesses 12e and 12f of the rotor member 12 are provided corresponding to the storage position and the fully deployed position of the mechanical key 10. If it is, it may be the structure which provided a pair of control protrusion 27a with the phase difference of 180 degrees in the circumferential direction.
