The problem with the above-mentioned conventional electronic component supply apparatus is that the cover tape is wound around the outer periphery of the first or second roller for feeding the cover tape, and is stored. There was a problem that it could not be stably pushed into the case.

[0004] That is, the cover tape is very thin, and when the cover tape is fed into the storage case while being sandwiched between the first and second rollers, the cover tape is made of the first or second cover tape. In this state, the tape is wrapped around the roller while being adhered to the second roller, thereby making it impossible to stably push the cover tape into the storage case.

It is an object of the present invention to stably feed the cover tape into the storage case.

[0006]

In order to achieve this object, the present invention provides a feeding means comprising first and second gears provided respectively on the front and back sides of a cover tape. The outer circumference of the first and second gears is provided with inclined teeth inclined with respect to the feeding direction of the cover tape, and the inclined teeth are formed of a harder material than the cover tape.

In other words, according to the above construction, the inclined teeth of the first and second gears are in contact with the cover tape, and the inclined teeth are not continuously in contact with the cover tape but at predetermined intervals. Each time it comes into contact with the cover tape. In addition, since the inclined teeth are inclined with respect to the feeding direction of the cover tape, the teeth are in contact with the cover tape as compared with a general gear in a direction perpendicular to the feeding direction of the cover tape. The abutment dimension to contact is longer, and furthermore, since this inclination is formed by something harder than the cover tape, the cover tape can be provided with irregularities alternately from its front and back surfaces. The cover tape can be reliably fed into the storage case without being wound around the first and second gears.

The above points will now be described in more detail. First, the cover tape is fed by the inclined teeth so that the cover tape can continuously contact the outer peripheral surface of the gear. Because there is no, this first, second
Means that the cover tape hardly adheres to the outer peripheral surface of the gear. Secondly, providing the first and second gears with the inclined teeth means that the inclined teeth contact the cover tape as compared with the case where the teeth in the direction perpendicular to the feeding direction are generally provided. The feed force increases as the contact dimension increases. Thirdly, since the inclined teeth are formed of a harder material than the cover tape, traces of the inclined teeth are alternately formed on the front and back surfaces of the cover tape from the first and second inclined teeth. As a result, the cover tape does not take a shape along the first and second gears, and as a result of these three, the cover tape fed by the first and second gears becomes the first or second gear. 2
Without being wrapped around the gear.
