Power supply unit having transformer-mounted substrate, and recording apparatus including power supply unit

摘要

A power supply unit including a components-mounted substrate on which a transformer is mounted, comprises a containing means including locking members for immobilizing and locking said components-mounted substrate in a direction parallel to the components-mounted surface of said components-mounted substrate, and integral restraining members that is integrally provided with said containing means to receive an impact force when an impact load is applied in a direction substantially orthogonal to said components-mounted surface, and/or restaining members which are part of said components-mounted substrate or said transformer to receive an impact force when the impact load is applied in a direction substantially orthogonal to said components-mounted surface, thus allowing said components-mounted substrate to be displaced and absorb an impact, and restraining a displacement whose magnitude is equal to or larger than a given magnitude so as to disperse the load. <IMAGE>
