PURPOSE:To execute securely a lead-in control by providing a switch lever for obstructing a lead-in, and releasing an engagement with a lead-in plate by an operating lever when a record disk is placed. CONSTITUTION:A switch lever 12 for obstructing a lead-in is supported to be freely rotatable on a sub-panel, and the engaging end 29c of a lead-in plate is engaged with its engaging part 12b, and in its stop state, it is held to an off by depressing a phono motor switch. When a record disk is placed, a record sensor 20 projects to the lower face, and a discriminating plate 19 for the presence or absence of a record and a resetting member 18 are turned clockwise, therefore, the pin 10b of an operating lever 10 moving together with a driving plate 4 presses with the switch lever 12 and turns it counterclockwise, and the lead-in is executed by releasing the engagement with the engaging end 29c. When there is no record, the pin 10b does not press with the lever 12. Therefore, a lead-in control can be executed securely. |
