In the fourth invention, in the pair of slide units, the holding portions protruding from each bar can simultaneously hold the electrodes of the plurality of thin batteries.

In the fifth invention, the tip of the holding section is tapered. In the sixth aspect, a pair of slide units each having two bars slidable by a drive source and having a holding portion protruding from these bars are provided corresponding to the electrodes of the thin battery. The slide of the slide unit is slid so that a plurality of sets of the sandwiching portions sandwich the plurality of electrodes of the thin battery with each other, and a contact provided on the sandwiching surface contacts the electrodes. Thus, an electrode contact method for a thin battery is provided.

(Operation) In the first invention, a slide unit having two parallel bars and a holding portion protruding from these bars is provided, and a pair of the slide units correspond to two electrodes of a thin battery. Installed. When one or both of the two crosspieces are slid by the driving source, the holding portions move so as to approach or separate from each other, and when approaching, the two holding portions form a set, and the electrodes of the thin battery are connected. It can be sandwiched and can be energized by the contact.

Since the electrode is held between the two holding portions protruding from the two crosspieces, even when the electrode is thin and easy to fall, the electrode is securely held and the contact of the contact can be stabilized. Since each of the holding portions is one set, if a plurality of sets are provided, it is possible to switch the energization to a plurality of batteries at the same time. The two bars may be slid so that one of the protruding holding portions is fixed and the other is approaching, and both holding portions are slid in the direction of approaching each other. Is also good. In this case, contact or separation can be performed in a short time.

The driving source may be a cylinder, solenoid, or other mechanical mechanism. In the second invention, the structure is simplified by using the air cylinder as a driving source. In the third invention, when the positions of the electrodes of the slide unit and the thin battery are distant from each other, one of the two is moved by the drive source so that the holding portions of each set can hold the electrodes. In general, it is easier to drive the slide unit.

According to the fourth aspect of the invention, in a pair of slide units, a plurality of sets of two holding portions are provided as one set and correspond to electrodes of a plurality of thin batteries, so that energization of a plurality of batteries can be simultaneously controlled. . In the fifth aspect of the present invention, the tip of the holding portion is tapered so that even if the electrode is about to fall, the electrode can be supported and held by the tapered portion, and more reliable contact can be guaranteed.

In the sixth aspect of the present invention, a pair of slide units having one or both slidable two bars and having a holding portion protruding from these bars are arranged corresponding to the electrodes of the thin battery. Accordingly, by sliding one or both of the two bars, and the two holding portions as a set to hold the electrode of the thin battery by a plurality of sets of holding portions, the contact contacts the electrode, It is now possible to reliably turn on and off the battery at the same time.

[0013] Compared to the conventional clipping of the electrode with a clip, it operates more quickly, and at the same time, it is possible to make contact with a large number of contacts. If the contacts are used in the four-terminal method, a more reliable contact effect can be obtained.
