2. Description of the Related Art Conventionally, a large number of works (chip type electronic parts, etc.) put into a ball of a vibrating ball feeder are aligned and carried in a spiral carrying groove, and the work of the vibrating type is carried out from the circumference of the ball. The balls are arranged so that they can be transferred to the linear conveying groove of the linear feeder, aligned and conveyed in the conveying groove of the linear feeder, and fed from the end of the linear feeder, for example, one by one to the next device in order. A feeder for conveying a work, which is configured by installing a feeder and a linear feeder close to each other, is widely used. However, there is a problem as described below, and a solution thereof has been demanded.

That is, conventionally, since a ball feeder and a linear feeder, which are independent devices each having a vibration source (magnet coil), are installed close to each other as a work transfer device, the vibrations of both are not synchronized, and therefore, If the connection between the two, that is, the end of the spiral feeding groove of the ball feeder and the tip of the linear feeding groove of the linear feeder are too close to each other, a collision due to vibration of each individual occurs, so that the amplitude of each feeder (0. A gap (0.2 to 0.3 x 2 = 0.4 to 0.6 mm) according to 2 to 0.3 mm
Rank) was set.

However, there is a work, such as a chip-type electronic component, which has a length of only 1.00 mm, and is caught or scratched in the gap between the two.
Since the respective ends of the carrying groove collide with the work when the two are transferred due to the non-synchronization of the vibrations of the two, there has been a great drawback in carrying the chip-type electronic component which is particularly susceptible to scratches and impacts.

Further, since the vibrations of both feeders are not synchronized, the work cannot be conveyed smoothly and at high speed, the conveyance efficiency is poor, and since each device is an independent device, a vibration source is required for each and the cost is high. There was also a drawback that it required an installation space.
