Japanese Patent Laid-Open No. 10-62568

  In solar cell watches that have been increasing in recent years, rechargeable storage batteries (secondary batteries) are used. This storage battery does not require battery replacement, and usually does not require the user to remove the battery from the watch module. However, since the power generation by the solar battery is not performed for a long time, and the pointer is stopped when the voltage of the storage battery is lowered (in an analog timepiece), the battery may be similar to a watch using a primary battery depending on the user. I misunderstood it was over and tried to change the battery myself. In that case, if you replace the secondary battery with the primary battery by mistake, the primary battery without the charging function will be charged and there is a risk of damage to the human body due to damage to the primary battery. is there. The conventional battery retainer structure as shown in FIG. 3 does not consider such a problem and is designed on the assumption that there is a battery replacement. Therefore, the user can easily remove the battery. The present invention has been made in view of such problems, and provides a battery holding structure in which a user cannot easily remove a battery. The user mistakenly reassembles a secondary battery into a primary battery. Is to prevent that.
