Abstract

A module including a circuit board, a conductive displacement section which is arranged along an outer periphery of the circuit board and displaced in response to a switching operation, and an antenna which is arranged on the circuit board along the outer periphery of the circuit board with one end oriented toward a direction of 3 o'"'"'clock or 9 o'"'"'clock and the other end oriented toward a direction of 6 o'"'"'clock or 12 o'"'"'clock.

Claims

1. A module comprising:

a circuit board;

a conductive displacement section which is arranged along an outer periphery of the circuit board and displaced in response to a switching operation;

an antenna which is arranged on the circuit board along the outer periphery of the circuit board with one end oriented toward a direction of 3 o'"'"'clock or 9 o'"'"'clock and the other end oriented toward a direction of 6 o'"'"'clock or 12 o'"'"'clock;

a housing in which the circuit board is arranged; and

a conductive plate for attaching the circuit board to the housing,

wherein the conductive plate is provided with the displacement section,

wherein a connection section which connects the conductive plate and the displacement section is provided between the conductive plate and the displacement section, and

wherein the connection section is arranged crossing a magnetic field of the antenna while corresponding to a longitudinal central portion of the antenna arranged along the displacement section.

2. The module according to claim 1,

wherein the antenna comprises:

a core formed in a bar shape; and

a coil wound around the core,

wherein the magnetic field is generated from the one end toward the other end in a longitudinal direction of the core.

3. The module according to claim 2,

wherein the conductive plate comprises a hook section for attaching the circuit board to the housing, and

wherein the displacement section or the hook section is not arranged on an extension of a central axis of the antenna.

4. The module according to claim 1,

wherein the conductive plate comprises a hook section for attaching the circuit board to the housing, and

wherein the displacement section or the hook section is not arranged on an extension of a central axis of the antenna.

5. The module according to claim 4,

wherein the conductive plate is provided with a clearance section for avoiding overlap with the antenna.

6. The module according to claim 4,

wherein another displacement section which is arranged adjacent to the hook section is provided on the conductive plate while corresponding to the other end of the antenna in a longitudinal direction, and

wherein the antenna is arranged on the circuit board with the extension of the central axis of the antenna being positioned between the hook section and the another displacement section.

7. The module according to claim 1,

wherein the conductive plate is provided with a clearance section for avoiding overlap with the antenna.

8. The module according to claim 1,

wherein a hook section for locking on the housing so as to attach the circuit board to the housing and another displacement section which is arranged adjacent to the hook section are provided on the conductive plate while corresponding to the other end of the antenna in a longitudinal direction, and

wherein the antenna is arranged on the circuit board with an extension of a central axis of the antenna being positioned between the hook section and the another displacement section.

9. The module according to claim 1,

wherein the antenna is obliquely arranged on 7 o'"'"'clock side of the circuit board with the one end being directed toward 8 o'"'"'clock side of the circuit board and the other end being directed toward the 6 o'"'"'clock side of the circuit board.

10. The module according to claim 1,

wherein a battery, a pressure sensor, and a magnetic sensor are arranged in areas which avoid the antenna, on one surface side of the circuit board on which the antenna is arranged.

11. The module according to claim 1,

wherein a movement comprised with a time indication function and a sub-display function, and a display device which electrooptically displays information are arranged on one surface side of the circuit board on which the antenna is not arranged, and

wherein components actualizing the sub-display function and the display device are respectively arranged in areas which avoid the antenna.

12. A timepiece comprising the module according to claim 1.
