A printer (10) has a body (11) with a solenoid assembly that includes a swingable plate (42). The swingable plate (42) can change posture between an engaged posture (S2), where the swingable plate (42) is electromagnetically attracted to a solenoid (412) and an engagement release posture (S1), where the solenoid (412) is demagnetized so that the swingable plate (42) is moved back by a coil spring (43) to perform a given operation. A noise reduction structure reduces a hitting sound of the swingable plate (42) relative to a stopper in connection with the change from the engaged posture (S2) to the engagement release posture (S1). In the noise reduction structure, the solenoid assembly is mounted to a drive plate (30) fixed to a frame of the body (11), and a positioning protrusion (212b) integrated with a 3-dimensional frame (20) is used as the stopper.
In an apparatus having an apparatus body provided with a solenoid assembly which includes a flapper designed to be changed in posture between an electromagnetically attracted posture where a solenoid is magnetized and thereby the flapper is electromagnetically attracted to the solenoid and a release posture where the solenoid is demagnetized and thereby the flapper is moved back by given biasing means and stopped by contact with a given stopper, a noise reduction structure for reducing hitting sound of the flapper relative to the stopper in connection with the postural change from the an electromagnetically attracted posture to the release posture, wherein:
