る。The amount of ascent or descent of the hydraulic cylinder (6) performed by one oil feeding by the oil feeding piston (8) is made to coincide with the thickness of one substrate (i). Therefore, when the trolley device (A) is used for supply, a predetermined number of unprocessed substrates (i) are placed on the mounting plate (2) located at the lowest position.
Each time the uppermost substrate (i) is picked up one by one by the vacuum pad (j) of the substrate transfer device from the state where the substrates are stacked and placed, one placing plate (2) is placed on each substrate (i). The thickness of the substrate (1) is increased by a certain amount so that the uppermost part of the stacked substrates (1) is kept at a constant height.

る。On the other hand, when the trolley device (A) is used for collection, the substrate (i) processed by the vacuum pad (i) is placed one by one on the mounting surface (23) located on the upper layer again. At the same time when they are stacked, the mounting plates (2) are lowered by the thickness of one substrate (i), and the uppermost part of the stacked substrates (i) is used when the trolley device (A) is used for supply. It is kept at the same level as the height of the top of the substrate (i).

ことができる。As described above, by keeping the uppermost part of the substrates (i) stacked on the trolley device (A) used for supply or recovery at the same level, the lower position of the vacuum pad (j) of the substrate transfer device can be set. The delivery level of the substrate (i) at the time of supply or recovery can be matched, and the delivery of the substrate (i) by the vacuum pad (j) can be reliably performed.

ることが可能である。Thus, according to the trolley device (A) configured as described above,
The substrate (i) can be freely moved while being mounted on the mounting plate (2). Therefore, when the trolley device (A) is used for supply, a predetermined number of substrates (i) are stacked on the mounting table (2) to be replenished and then transported to the base (3) below the supply position. The supply can be started as it is, and after the predetermined number of substrates are collected from the transfer device at the collection position, the collected processed substrates (i) are placed on the mounting plate (2) for a predetermined period. Can be transported to the storage place.
従って、従来の様に基板の補給と回収の度に大変に重い
基板（ｉ）の束を積み降ろしする必要がなくなり、基板
（ｉ）の補給と回収作業を楽に行なうことができるもの
である。Therefore, it is not necessary to load and unload a very heavy bundle of substrates (i) each time the substrate is replenished and collected, which makes it possible to easily perform the substrate (i) replenishment and collection work.
上記した様に、台車装置（Ａ）は、基板搬送装置に対
し、基板（ｉ）の供給用として、又は回収用として単独
に使用することができるが、同じ台車装置（Ａ）を２台
用意し、その一台を供給用として、もう一台を回収用と
して同時に使用することもできる。As described above, the trolley device (A) can be independently used for supplying or collecting the substrate (i) to the substrate transfer device, but two same trolley devices (A) are prepared. However, one of them can be simultaneously used for supply and the other for recovery.
この様に使用すれば、供給用の台車装置（Ａ）から供給

る。When used in this way, both the supply and recovery trolley devices (A) are processed in a state where the predetermined number of substrates (i) supplied from the supply trolley device (A) are processed and then all are recovered by the recovery trolley device. ), The switching mechanism (b) switches the switching valve (9) to automatically convert supply for collection and conversely for collection to supply. It can be used efficiently by exchanging with the recovery position.
