摘要:
A pin platen mechanism includes coiled springs mounted in respective retaining holes formed in a sprocket wheel for biasing respective sprocket pins to the outside at all times. A cam groove in a cam member has freely fitted therein projections of the sprocket pins. A wider part of the cam groove enables the pins to be withdrawn inwardly only when necessary.
