Magento自定义管理页面，其URL位于adminpath之外

I am trying to build a custom Magento module which creates an admin page in Magento. I have everything working fineexcept the admin page url is domain.com/index.php/module/controllername/function/ when it should be domain.com/index.php/adminpath/module/controllername/function/

    <Module>
            <use>admin</use>
            <args>
                <module>Developer_Module_Adminhtml</module>
                <frontName>Module</frontName>
            </args>
        </Module>

    </routers>
    <!--<routers>
       <adminhtml>
            <args>
                <module>
                    <Developer_Module after="Mage_Adminhtml">Developer_Module_Adminhtml</Developer_Module>
                </module>
            </args>
       </adminhtml>
    </routers>-->

And my admin menu link is

<menu1 translate="title" module="Module">
            <title>Developer</title>
            <sort_order>60</sort_order>
            <children>
                <menuitem1 module="Module">
                    <title>Page Link</title>
                    <action>module/function</action> //setting this adminhtml/module/function just gives 404 but changes url to what i want
                </menuitem1>
            </children>                
        </menu1>

So i'm wondering how i set my module to be within the standard admin path properly?
