In, the antenna 102 is built in the band 8 by the packing 2 with built-in antenna. Packing 2 with built-in antenna
Is held between the side 1 and the back lid 3 (see FIG. 1). The antenna 102 is connected to the receiving circuit 104 in the side 1 via the antenna connecting portion 103. The receiving circuit 104 outputs a signal to the arithmetic circuit 105 by a radio wave signal from the antenna 102. The arithmetic circuit 105 arithmetically processes the signal from the receiving circuit 104 and displays various kinds of information on the display element 106. The arithmetic circuit 105 also causes the display element 106 to display time information in accordance with a signal from the clock circuit 110.

FIG. 5 is a plan view showing the embodiment of FIG. 2 with the back cover removed. FIG. 6 is an enlarged cross-sectional view showing the mutual relationship of the packing 2 with a built-in antenna, the back cover 3, the band 8 and the like of the embodiment of FIG. FIG. 7 is a plan view of the back cover according to the present invention.

It is fitted into the packing concave portion 14 provided on the side 1 corresponding to the packing convex portion 5. The side recesses 14 on the side 1 are arranged at intervals of two places on both end surfaces of the back opening on the side 1. Further, the packing protrusions 5 provided at four positions of the packing 2 with a built-in antenna are provided at positions corresponding to the side recesses 14 provided on the circular flat surface of the side 1, and two positions are provided at both end faces in the band direction. The packings 5 are arranged at intervals, and the packing protrusions 5 are fitted into the side recesses 14 to prevent deformation of the packing 2 with a built-in antenna.

In FIG. 6, the back cover projection 6 is provided on the end face in the longitudinal direction of the back cover 3 along the outer shape of the end face in the longitudinal direction of the back cover as shown in FIG. It is provided in a linear shape that stands upright in the direction of 1. In addition, the back cover projection aligning groove 12 provided on the packing 2 with built-in antenna corresponds to the projection 6 of the back cover (see FIG. 6 and FIG. 7) on the outside of the packing protrusion 5 provided on the packing 2 with built-in antenna. It is provided in a linear shape orthogonal to the longitudinal direction of the side 1. With this configuration, when assembled, the back cover projection 6 is embedded in the back cover projection alignment groove 12 of the antenna built-in packing 2 to fix the antenna built-in packing. As a result, the packing 2 with a built-in antenna is further pressed by the back cover 3 to prevent plastic deformation.

As shown in FIG. 5, the storage section 7 is provided on the back surface (arm side) of the band 8. The storage portion 7 stores the antenna built-in portion 11. The antenna built-in portion 11 extends to either one of the upper and lower bands attached to the side 1 of the antenna built-in packing 2.

The storage portion 7 is a rectangular pocket-shaped storage portion which protects the antenna built-in portion 11 and has an integral structure with a band which is a watch exterior component.

[0016]

According to the present invention, in a wristwatch type electronic device having circuit wiring in the band, an antenna member guided from the inside of the case in the band direction of the waterproof rubber packing inserted over the entire circumference of the overlapping portion of the case and the back lid is provided. Since it is configured to be built in, it has the following effects. (1) Unlike conventional wristwatch type electronic devices having circuit wiring in the band, connector packing is not required. (2) It suffices to form a portion for housing the antenna, and complicated molding such as band integral molding is not required. (3) Since it is possible to rotatably support the band without fixing the band to the case with screws, the wearability of the band is improved.
