Provided are a laser-bonded component and a production method for same that ensure sufficient bonding strength using little laser energy and which cause little increase in surrounding temperature. A nickel layer, being a surface layer, is formed having sufficient thickness on the upper surface of a copper plate that is uppermost amongst at least two superposed copper plates, a laser is irradiated from above the nickel layer, a re-solidification section formed by fusing and alloying the copper in the copper plates and the nickel in the nickel layer is formed through to inside the bottommost copper plate, and the copper plates are bonded together. The re-solidification section having high breaking strength is formed by the alloying of the nickel and the copper. As a result, the copper plates can be bonded with a small welding surface area and little laser energy.

A compact cash register comprises a first member for freely adjusting the visual angle of the same. The first member is connected to a second member of a casing of the compact cash register so as to provide in order to adjust the visual angle of the cash register. The first member comprises a ball biased continuously by a spring. The second member includes a cavity formed on the surface of a cover of the casing. The connection between the first member and the second member allows the compact cash register to be supported obliquely. The connection may be formed as a ratchet mechanism, a pivotal mechanism and the like. The casing comprises at least two compartments each containing the compact cash register and cash, the two compartments being adjacent to each other.
