In addition, since there is no need for an installation space for a dedicated unlocking restricting member, the overall size of the timepiece module 12 can be reduced.

In this case, in this timepiece module 12, each of the first to third connectors 24 to 26 has a connector main body 27 and a lock lever 28, and the board insertion portion 27a of the connector main body 27 is provided with the first to third connection boards 20 to 26. 22 is inserted, and in this state, the lever main body 28a is rotated about the support shaft 28b of the lock lever 28, and the first to third connection boards 20 to 22 are pressed against the inner surface of the board insertion portion 27a. - The third connection boards 20 to 22 can be securely fixed to the connector main body 27 .

In addition, in the timepiece module 12 of this wristwatch, when the lock levers 28 of the first to third connectors 24 to 26 are locked, the battery 14 is arranged close to each lock lever 28 in a non-contact state. As a result, even if the lock levers 28 of the first to third connectors 24 to 26 try to rotate around the support shafts 28b due to an impact or the like, the lock levers 28 abut against the battery 14. It is possible to reliably and satisfactorily regulate the 3-connectors 24 to 26 so that the locked state by the lock levers 28 is not inadvertently released.

In this case, in the timepiece module 12 of this wristwatch, the battery storage section 15 for storing the battery 14 is provided with the housing 13 which is a battery holding member provided corresponding to the first to third connectors 24 to 26. , the battery housing portion 15 of the housing 13 can reliably positionally regulate the battery 14 in a state corresponding to the first to third connectors 24 to 26 .

In this case, in this timepiece module 12, the lower surface of the battery 14 housed in the battery housing portion 15 of the housing 13 is pressed by the battery holding plate 16, and the upper surface of the battery 14 is an electrode plate 30 provided on the circuit board. , so that when the lock levers 28 of the first to third connectors 24 to 26 are in the locked state, the upper surface of the battery 14 approaches the lock levers 28 in a non-contact state, That is, they can be arranged accurately and favorably with a slight gap S.

Furthermore, in this timepiece module 12, a plurality of the first to third connectors 24 to 26 are provided corresponding to the periphery of the battery 14 housed in the battery housing portion 15 of the housing 13, so that one battery 14 , the release of the locked state by the lock levers 28 of the first to third connectors 24 to 26 can be reliably and satisfactorily regulated. Therefore, it is not necessary to individually regulate the release of the locked state by the lock lever 28 of each of the first to third connectors 24 to 26, so that the number of parts can be further reduced and the overall size of the timepiece module 12 can be reduced. can be improved.

In the above-described embodiment, the first to third connectors 24 to 26 are configured to lock the first to third connection boards 20 to 22 to the connector body 27 by rotating the lock lever 28. However, the present invention is not limited to this, and may have a structure in which the first to third connection boards 20 to 22 are locked to the connector main body 27 by sliding a lock lever, for example. In this case, the sliding of the lock lever may be restricted by the outer peripheral edge of the battery 14 .

Furthermore, in the above-described embodiments, the case of application to a wristwatch has been described, but the present invention does not necessarily have to be a wristwatch, and can be applied to various types of timepieces such as travel watches, alarm clocks, table clocks, and wall clocks. can. Moreover, the present invention does not necessarily have to be a watch, and can also be applied to electronic devices such as mobile phones and portable terminals.

Although one embodiment of the present invention has been described above, the present invention is not limited to this, and includes the invention described in the claims and their equivalents.
The invention described in the claims of the present application will be additionally described below.
