This magazine is mounted on an automatic assembling machine, the tray is moved into the automatic assembling machine as required, and microelectronic components are mounted on the substrate or the like from this tray by using a handling arm.

[0003]

By the way, this type of magazine is provided with a shutter plate or a bar,
This shutter plate or bar prevents the trays contained in the magazine from coming out of the magazine during movement of the magazine or automatic assembly. The shutter plate or bar is manually operated by an operator, and the shutter plate or bar is manually opened after mounting the magazine on the automatic assembly machine. As a result, the tray in the magazine is moved or loaded into the automatic assembly machine. Therefore, there is a problem that the manual opening of the shutter plate or the bar is complicated as the number of magazines increases.

Further, when the magazine is attached to the automatic assembly machine, the magazine is positioned only by aligning the outer periphery of the magazine with the mounting opening of the tray changer of the automatic assembly machine. In such a positioning method, when using a plurality of magazines, it is difficult to obtain the accuracy of mounting each magazine, and the operator's attention is required when mounting the magazines or loading the trays. In particular, when the magazine is moved in the tray changer of the automatic assembling machine, there is a drawback that the magazine is likely to be displaced and that the magazine cannot be moved at high speed.

The present invention has been made in view of the above-mentioned problems, and an operator does not have to open a shutter for keeping a tray in a magazine, and the magazine can be attached to an object such as an automatic assembling machine. It is an object of the present invention to provide a component tray storage magazine for storing a component tray that can be easily and easily positioned.

[0006]

According to the present invention, there is provided a magazine for accommodating trays on which components are mounted, a shutter that is openably and closably attached to the magazine, and the shutter is closed. It has a biasing means for preventing the tray from coming out of the magazine and a positioning means for positioning the magazine with respect to the object to be mounted, and drives the drive unit from the outside against the force of the biasing means. This is achieved by a component tray storage magazine in which the shutter is opened by force and the tray can be taken out from the magazine.

[0007]

According to the above construction, the shutter is always closed. Therefore, in this state, the accommodated tray is stably held in the magazine. Further, the tray can be pulled out or put into the magazine by opening the shutter against the force of the spring, which is the urging means, by the solenoid, which is the external drive unit. Further, the magazine can be reliably positioned by the positioning means with respect to the object to be mounted, for example, the automatic assembly machine. This positioning means is, for example, a positioning hole.
