プリンタの用紙有無検出機構。 A device for detecting the presence or absence of paper set on a platen of a serial printer includes a paper pan provided around the outer periphery of the platen to guide the paper to the platen, and a paper rest arranged with an appropriate gap from the paper pan. a microswitch installed near the paper pan to detect the presence or absence of paper; a swingable microswitch lever that constitutes a part of the microswitch and operates a contact point; and the paper pan and paper rest. The end of the micro switch lever is provided with a through hole drilled in the hole so that the end of the micro switch lever can be engaged from the paper pan to the paper rest, and the end of the micro switch lever is curved into a spherical shape and cut into a cross shape. A paper presence/absence detection mechanism for a printer, characterized in that the paper presence/absence detection mechanism is configured as follows.
