【発明の詳細な説明】
本発明は、電子時計用回路基板の新規な改良に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel improvement of a circuit board for an electronic watch.
従来より、リードフレ−ムに樹脂層を形成（トランスフ
アモールド）して回路基板とする技術は知られているが
、アナログ電子時計に必要な歯車は金属製の地板で軸受
されており、回路基板と地板とを重ね配置すると、時計
全体が厚くなってしまうという欠点があった。Conventionally, the technology of forming a resin layer on a lead frame (transfer molding) and using it as a circuit board has been known, but the gears necessary for analog electronic watches are supported by a metal base plate, and the circuit board If the main plate and the main plate were placed one on top of the other, the disadvantage was that the entire watch would become thicker.
本発明は、上記欠点を速やかに解決するための極めて効

たものである。The present invention provides an extremely effective main stage for quickly solving the above-mentioned drawbacks.The present invention provides a very effective main stage for quickly solving the above-mentioned drawbacks. The purpose of this invention is to provide a low-cost circuit board for an electronic watch that is thin and has a small number of parts by forming a bearing of a gear in an exposed portion.
以下、図面に従って本発明を詳細に説明する。Hereinafter, the present invention will be explained in detail with reference to the drawings.

受として作用している。The drawing shows a preferred embodiment of the present invention, in which 1 is a lead frame to which circuit elements are connected, 2 is connected to the lead frame 1 by wire bonding, and 4 is connected to the lead frame 1 via solder 3. capacitor, 5 is IC
A resin layer 6 is molded on a desired portion of the lead frame 1 including the connection portion 2, and a screw pin 6 is connected to the lead frame through the resin layer 5.
If a lead wire such as a motor (not shown) is connected with a screw, conduction can be established, and it can also function as a contact terminal. 7
is a recess formed in the resin layer 5, 8 is a key protrusion of the lead frame 1, 9 is a gear housed in the recess 7, 10 is a hole formed through the lead frame 1 and the resin layer 5, The shaft portion 9a of the gear 9 is inserted into the hole 10, and the exposed portion 8 or hole 10 of the lead frame 1 acts as a bearing for the shaft portion 9a.

とができる。As described above, according to the present invention, a recess for storing a gear and a hole for bearing the gear are formed in the resin layer of the circuit board,
Since the gear is directly supported by the exposed portion or hole of the lead frame, it is possible to provide a circuit board for an electronic timepiece that has a bearing function and is thin and has a small number of parts.
又、従来回路基板に設けられた注油用の穴も不用となり
、孔１０を介して直接注油することができる効果も有す
る。Furthermore, the hole for oiling conventionally provided in the circuit board becomes unnecessary, and there is also the effect that oil can be directly poured through the hole 10.
