    摘要: A simplified method of and apparatus for mounting an electronic part such as a transistor on a circuit board. Two or more selected ones of terminals of an electronic part are angularly bent in prior, and when the electronic part is to be mounted on a circuit board, the terminals are forcibly inserted into through-holes of the circuit board to an extent wherein bent portions of the terminals are projected below the circuit board. As a result, if a weak force is applied to pull the part off, the bent portions of the terminals will frictionally engage with edges of the through-holes to prevent the part from being removed from the board.

    摘要: A print ribbon cassette of a simplified construction which can prevent slackening of a print ribbon and normally keep the print ribbon in taut condition for printing. The print ribbon cassette comprises a lock member having a locking position for preventing inadvertent rotation of a feed spool on which a print ribbon to be supplied is wound. The cassette further comprises a ribbon lock control member which is moved between an operative position and an inoperative position in response to a tensile force of a print ribbon applied thereto. In the operative position of the ribbon lock control member, it engages with the lock member and holds the same to the lock position.
